DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a telephone system in which a number dialed from a low-priority general telephone is registered in advance in a telecommunications network during outgoing and incoming switching at an originating exchange installed in the telecommunications network. If it is a number, the present invention relates to a priority connection method of a telephone in an intelligent network in which a priority level is raised even for a call to an outgoing connection restriction destination and the call is communicated as a priority call.

[0002]

2. Description of the Related Art Congestion in an electronic exchange installed in a telecommunications network is described in "To understand the NTT communication network" (Ohm Co., Ltd.). The system is roughly divided into three types.

[0003] The incoming call congestion is broadly classified into subscriber congestion in which calls to specific subscribers are concentrated and regional congestion in which calls to specific areas are concentrated due to a call in a disaster or the like. ,
The occurrence of congestion is detected, the subscriber and the area that are causing the congestion are detected, and the originating exchange side regulates outgoing connection of calls to the congested subscriber and the congested area.

In outgoing connection regulation, calls to the destination of congestion from emergency telephones such as police and fire departments and public telephones having high publicity are regulated more slowly than calls from general telephones, that is, priority is given to priority. Communication is secured by raising the level.

For this reason, if a disaster occurs near the home when the user is away from home due to work or business trip, and the exchange accommodating the home telephone is congested by the incoming call due to local congestion,
Outgoing exchanges restrict outgoing calls to congested areas, so even if you try to call home to check the safety of your family at home in such a situation, calls from ordinary telephones will not be accepted. Since connection is restricted, it is necessary to make a call from a public telephone having high publicity.

However, it is very inconvenient to search for a public telephone when it is necessary to check the safety of a family as soon as possible.

Therefore, Japanese Patent Laid-Open Publication No. 3-19560 discloses a method of treating a specific call from a general telephone without restricting outgoing / incoming connections and treating the same call as from a public telephone. Priority subscriber connection control method '' is applied to outgoing connection regulation from general telephones, that is, outgoing connection regulation of non-priority calls with low priority level. The called telephone number of the called subscriber is registered in the exchange, and if the called telephone number dialed from the general telephone is in the outgoing / inbound restricted area, the registered called telephone number of the specific called subscriber is registered. If a match is found, the connection operation is performed as a priority call, so that a specific call from a general telephone can be excluded from outgoing connection restrictions and treated in the same way as when a call is made from a public telephone. Possible That.

However, with only the above method, if calls treated as priority calls from general telephones are concentrated from all over the country, regulation of exchanges which are congested does not work, causing further congestion in the incoming system. There is a risk that it will.

As a solution to such a problem, the priority level of a priority call from a general telephone is raised over a priority call from a public telephone, and a call from a public telephone is treated as a conventional priority call. Calls to specific telephone numbers and calls from emergency telephones such as police and fire departments can be dealt with as top priority calls, and finer outgoing connection control according to the priority level can be dealt with. However, if a call treated as the highest priority call from the same general telephone is permitted many times by the above method, the priority call from the public telephone is squeezed, and the publicity of the public telephone may be impaired.

As a solution to this, Japanese Patent Laid-Open Publication No. Hei 5-22413
Number of calls that allow outgoing / exiting to a regulated destination as a priority call for a specific call from a general telephone by applying the “terminating restriction device in exchange” disclosed in Japanese Patent Publication No. The problem can be solved by setting an upper limit value for.

[0011]

However, if it is attempted to secure a specific call to an area where connection is restricted even from a general telephone by using the above-mentioned two conventional techniques, the originating exchange side is required. Since it is necessary to register the incoming telephone number of the above-mentioned specific called party with respect to the specific telephone, there is a problem that the general telephones and calling exchanges that can make outgoing calls as the highest priority call are limited.

In addition, when a specific telephone number is registered as a highest priority call in a public telephone, the specific telephone number cannot be registered due to the public nature of the public telephone. There is a problem that you can not.

In the method disclosed in Japanese Patent Laid-Open Publication No. Hei 5-22413, in which the number of call counters is initialized at regular intervals, the larger the number of call counters to be initialized, the more the initial setting is required. There is a problem that the number of processes increases and the effect on the processing capability of the system increases.

The present invention has been made in order to solve such a problem, and it is possible to register in a telecommunications network in advance regardless of whether a calling telephone is from a general telephone or a public telephone. For a specific telephone number from a specified subscriber number, even if calls to that area are outgoing and outgoing, the call of the specific telephone number is passed as a priority call, and furthermore, incoming call congestion occurs. It is an object of the present invention to provide a telephone priority connection method that can minimize the influence on the incoming call exchange.

[0015]

In order to achieve the above object, the present invention provides an intelligent network for providing an advanced communication service by separating a telecommunications network into a service operation layer, a service control layer, and a service management layer. The priority connection service is defined as one service, and the "contract subscriber number" of the subscriber who contracts the priority connection service, and the "priority connection destination subscriber number" which is treated as a priority call even when the outgoing connection is restricted. Is registered in the database provided in the service control hierarchy with the "subscriber subscriber number" as a search key and the configuration of the database searched by the contract subscriber number. In the element, the number of times the priority connection is permitted is stored so as not to exceed the upper limit of the number of calls for which the priority connection is permitted within a certain time determined by the system. A priority connection call number counter and an initial priority connection timestamp for storing a time at which priority connection is first permitted to determine whether a predetermined time has elapsed are provided and accommodated in the service operation hierarchy. "Service identification number" determined by the system from the subscriber
When the above "contract subscriber number" and "priority connection destination subscriber number" determined at the time of the service contract are dialed, an inquiry is made to the service control layer as to whether or not the priority connection is permitted. The service control layer determines whether the dialed "subscriber subscriber number" and "priority connection destination subscriber number" are registered in the database, and if they are registered, the "priority connection call" Number Counter "
And the “first time priority connection timestamp”, it is determined whether or not the number of calls that allow the priority connection within a predetermined time predetermined in the system is within the upper limit value, and only when the number is within the upper limit value, The priority connection call counter is updated and a response indicating that the priority connection service is permitted is returned. Otherwise, a response indicating that the priority connection service is not permitted is returned, and as a result of the inquiry, the priority connection service is permitted. When a response is received, even a general telephone with a low priority level is treated as a priority call.

[0016] In addition to the "subscriber subscriber number" and the "priority connection destination subscriber number", a plurality of users can receive a preferential connection service with the same contract content for one subscriber. A plurality of “user identification numbers” are provided, and a database configuration that can manage a “priority connection call counter” and “first priority connection timestamp” for each user identification number,
It is characterized in that the number of calls for which priority connection is permitted within a fixed time is controlled for each user identification number.

Further, for a priority connection service contractor who has once been able to make a call, even if the priority connection call counter exceeds the upper limit of the number of calls permitted to perform priority connection within a certain time determined by the system. Even if there is no call, control is performed such that the priority connection service is not permitted within a certain period of time after a successful call.

[0018]

According to the present invention, the "subscribed subscriber number" of the subscriber who has previously contracted the priority connection service in the telecommunications network.
And the "priority subscriber number", which is treated as a priority call even when outgoing and incoming calls are restricted, so that no matter which general telephone is used to make a call, If the user number and the priority connection destination subscriber number are dialed, the call of the priority connection destination subscriber number can be connected as a priority call even if a call to the area is under outgoing connection restriction.

In addition, since the number of calls to be connected as priority calls within a certain period of time is limited for each priority connection service contractor, the influence on the terminating exchange which is congested by the terminating system can be minimized.

Further, by controlling the number of calls for which the preferential connection is permitted for each "user identification number", the preferential connection is not biased to a specific user, and a plurality of users can perform the preferential connection under the same conditions. Service is available.

In particular, according to the present invention, by controlling not to allow the priority connection service within a certain period of time from the success of the call, it is possible to reduce the number of calls to the incoming congested ground.
It is possible to increase the possibility that a user who has not successfully made a call will have a successful call.

Furthermore, since whether or not a predetermined time has elapsed is determined for each request when a request for the priority connection service is generated, it is not necessary to initialize all call counters at regular intervals, and the number of calls can be reduced. Since the processing required for the initial setting of the counter is dispersed, the influence on the processing capacity of the system can be reduced.

[0023]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the illustrated embodiments.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In FIG. 1, the service management device 108 corresponds to the service management layer 109 in the intelligent network, the service control device 103 and the database 102 correspond to the service control layer 101 in the intelligent network, and the exchange 112 and the switching network 116 are intelligent. This corresponds to a service operation layer 111 in the network, and the service control device 103 and the exchange 112 are connected by a signaling network 110.

The service control unit 103 includes a database access unit 104, a priority connection service permission determination unit 10
5. Communication control unit 106, priority connection service registration unit 107
It is composed of

The exchange 112 is connected to the communication control unit 11.
3. Priority connection service operation unit 114, exchange operation unit 115
The exchange operation unit 115 includes many telephones 1
17 are connected.

FIG. 2 is a diagram showing the configuration of the database 102 provided in the service control layer 101. The database 102 is searched by the contracted subscriber number 201 of the subscriber who has contracted the priority connection service, and stores a telephone number of a destination to be connected with priority specified at the time of the service contract. A priority connection call counter 203 for storing the number of calls for which priority connection is permitted so as not to exceed the upper limit of the number of calls for which priority connection is permitted within a certain time determined by the system; The first priority connection time stamp 204 stores the time at which the priority connection was first permitted to determine whether or not the priority connection was permitted.

The contracted subscriber number 201 of the subscriber who has contracted the priority connection service and the priority connection destination subscriber number 202 which is the telephone number of the destination to which the connection is preferentially made are provided by the service management device 108 at the time of the service contract. The notification is sent to the priority connection service registration unit 107 of the control device 103, and the database 10 is notified via the database access unit 104.
2 is stored.

When the subscriber of the telephone set 117 uses the priority connection service, a "service identification number" determined by the system, which indicates the priority connection service.
And "contract subscriber number 201" and "priority connection destination subscriber number 20" registered in database 102 at the time of contract.
This is realized by dialing "2".

When these series of numbers are dialed in from telephone set 117, notification is given from exchange operation unit 115 of exchange 112 to priority connection service operation unit 114, and service control unit 103 is transmitted by communication control unit 113 via signal network 110. From the communication control unit 106 to the priority connection service allowance determination unit 105 is notified of the "contract subscriber number" and the "priority connection destination subscriber number" dialed by the calling subscriber,
The priority connection service permission determination unit 105 issues a request to determine whether the number is a number permitted for the priority connection service.

In the priority connection service permission determination unit 105,
Database 1 via database access unit 104
02 to determine whether or not the notified number can be preferentially connected.
Return the determination result to 2.

Priority connection service control unit 1 of exchange 112
In 14, it is determined whether or not to connect as a priority call based on the determination result, and the call connection operation is entrusted to the switching operation unit 115.

The switching operation unit 115 performs outgoing connection restriction processing according to the prior art. However, in the case of a priority call, the outgoing connection restriction is not performed. Requests telephone 117 to be called.

FIG. 3 is a flowchart showing a processing flow of the priority connection service permission determination unit 105 of the service control device 103.

In FIG. 3, it is checked whether or not the contracted subscriber number 201 notified from the exchange 112 is registered in the database 102 (step 301). Is set (step 314), and the exchange 112 is notified.

However, when the subscriber number 201 notified from the exchange 112 is registered in the database 102, the subscriber number 20 is stored in the database 102.
1 is used as a search key to extract the priority connection destination subscriber number 202 (step 302), and it is determined whether the priority connection destination subscriber number notified from the exchange 112 matches the priority connection destination subscriber number 202. (Step 303) If the values do not match, "non-permissible" is set as the determination result (Step 31).
4) Notify the exchange 112.

If it is determined in step 303 that they match, the priority connection call number counter 203 is extracted from the database 102 (step 304), and it is determined whether or not the extracted priority connection call number counter 203 is "0" (step 304). Step 30
5) In the case of "0", since it is the first connection request, "1" is added to the priority connection call counter 203 (step 306). Next, the current time is set in the first priority connection time stamp 204 of the database 102 (step 30).
7) Finally, "acceptable" is set as the determination result (step 3).
18) Notify the exchange 112.

In step 305, the priority connection call number counter 2
03 is not "0", the database 10
2, the first priority connection time stamp 204 is extracted (step 309), and it is determined whether or not a fixed time determined by the system has elapsed (step 310).
If it is determined that the predetermined time has elapsed, priority connection is possible again, so that the priority connection call number counter 203 indicates "
"0" is set (step 311), "1" is added to the priority connection call counter 203 (step 306), and the current time is set to the first priority connection time stamp 204 (step 307). Is set to "permitted" (step 308), and the exchange 112 is notified.

If it is determined in step 310 that the predetermined time has not elapsed, the priority connection call number counter 203 determines whether or not the number is equal to or less than an upper limit value that allows connection within a predetermined time (step 312). If the value is equal to or more than the value, "non-permissible" is set as the determination result (step 314), and the exchange 11
Notify 2.

If it is determined in step 312 that the value is less than the upper limit value, "1" is added to the priority connection call counter 203 (step 313), and "permitted" is set in the determination result (step 308). Notify 112.

FIG. 4 is a flowchart showing a processing flow of the priority connection service operation unit 114 of the exchange 112.

The priority connection service operation unit 114 inquires of the service control unit 103 whether or not the number information dialed by the calling subscriber can receive the priority connection service (step 401), and determines the result (step 401). Step 402).

When the result of the determination is "acceptable", the switching operation unit 115 is notified of the highest priority call (step 403).

However, if the judgment result is "non-permissible",
It is determined whether the telephone dialed by the subscriber is a public telephone or a general telephone (step 404). If the telephone is a public telephone, the switching operation unit 115 is set as a priority call as in the prior art.
(Step 405), and in the case of a general telephone, notifies the switching operation unit 115 as a non-priority call as in the prior art (step 406).

In the switching operation unit 115, outgoing / incoming connection control using a priority level according to the prior art is performed.

As described above, the "contracted subscriber number" of the subscriber who contracts the priority connection service, the "priority connection destination subscriber number" treated as a priority call, and the number of times of performing the priority connection are stored. A database 102 composed of a “priority connection call counter” and a “first priority connection timestamp” storing the time of the first priority connection is provided, and a “service identification number” and a “contract subscription” are provided by the subscriber. If the "user number" and the "priority connection subscriber number" are dialed, it is determined whether the "contract subscriber number" and the "priority connection subscriber number" are registered in the database 102. And if it is registered, it is determined whether or not the number of calls that allow priority connection within a certain time is within the upper limit,
By permitting the priority connection service only when it is within the upper limit, if you dial the contracted subscriber number and the priority connection destination subscriber number from any general telephone, Even if a call to the area is under outgoing connection restriction, a call with the priority connection destination subscriber number can be connected as a priority call.

In addition, since the number of calls to be connected as priority calls within a certain period of time is limited for each priority connection service contractor, the influence on the terminating exchange which is congested by the terminating system can be minimized.

Further, since it is determined for each request when a request for the priority connection service has occurred, whether or not a certain time has elapsed, it is not necessary to initialize all the call number counters every certain period, and the call number counter is not required. Since the processing required for the initial setting is dispersed, the influence on the processing capacity of the service control device can be reduced.

In the example of FIG. 4, the embodiment in which the three priority levels of the highest priority, the priority, and the non-priority are set has been described. Even when the control is performed with one priority level, it can be easily handled by treating the portion treated as the highest priority call in step 403 as a priority call.

FIG. 5 is a diagram showing another example of the configuration of the database 102 provided in the service control hierarchy 101.

The difference from the configuration of the database 102 shown in FIG. 2 is that a plurality of users can receive a priority connection service with the same contract content for one contractor.

In the database configuration shown in FIG. 5, the contract subscriber number 201 and the priority connection destination subscriber number 202 are the same as those in the database configuration shown in FIG. A user A identification number 501, a user B identification number 502, a user C identification number 503, and a user D identification number 504 are provided so that the service can be simultaneously received. Register any number of.

Further, in order to manage the upper limit value of the priority connection within a fixed time for each user, the user A priority connection call number counter 505 and the user A first time Priority connection timestamp 506,
User B priority connection call number counter 507, User B first priority connection time stamp 508, User C priority connection call number counter 509, User C first priority connection time stamp 5
10, User D priority connection call number counter 511, User D
As a database configuration to which the first priority connection time stamp 512 is assigned, the priority connection service permission determination shown in FIG. 3 is performed for each user identification number.

When the subscriber of the telephone set 117 uses the priority connection service, in addition to the “service identification number”, the “contract subscriber number” 201, and the “priority connection destination subscriber number” 202, the “use” Person identification number "501, 502, 50
Dial 504 for dialing.

Then, in the processing of the priority connection service determination unit shown in FIG. 3, it is determined whether or not the user identification number dialed matches the user identification number registered in the database 102, and it does not match. In that case, the priority connection service is not allowed.

As described above, by controlling the number of calls for which the preferential connection is permitted for each "user identification number", the preferential connection is not biased to a specific user, and a plurality of users can be controlled under the same condition. You can receive priority connection service.

In the above embodiment, the calling subscriber dials the "contract subscriber number". However, the priority connection service contractor uses the "contract subscriber number" declared at the time of the contract. When receiving the priority connection service from the same telephone, if the originating telephone is an analog telephone, the subscriber number of the telephone originating at the local exchange where the analog telephone is accommodated is known, and the priority connection is made from the digital telephone or the mobile telephone. When receiving services,
Since the subscriber number is notified from the calling telephone to the local exchange, there is no need for the caller to dial the "contract subscriber number".

For this reason, a service identification number different from the above-described “service identification number” is provided, and whether or not the “subscriber subscriber number” is dialed is determined by the local exchange side, and the “subscriber subscriber number” is determined. When the "number" is not the "service identification number", the effect of the present invention does not change even if a method of assigning the "contract subscriber number" on the subscriber exchange side and notifying the service control apparatus 103 is adopted.

In the above embodiment, as can be seen from the flowchart of the priority connection service operation unit 114 shown in FIG.
06, step 313), priority connection call number counter 203
In the switching operation unit 115, "1" is added to the priority connection call number counter 203 immediately before transition to the call.

For this reason, even after a call can be made with the priority connection destination subscriber, the upper limit value of the number of calls permitted to perform a priority connection within a predetermined time determined by the system is set to the priority connection call number counter 2.
Until the number exceeds 03, the priority connection service can be received any number of times within the range not exceeding the upper limit value, and there is a possibility that the number of calls to the ground due to congestion of the incoming system does not decrease.

Therefore, once the priority connection service contractor has successfully made a call, the priority connection call number counter 20
3 does not exceed the upper limit of the number of calls that allow priority connection within a certain period of time defined by the system,
By not allowing the priority connection service within a certain period of time from the success of the call, it is possible to reduce calls to the destination congested ground.

A database 102 for realizing this.
6 is shown in FIG.

In FIG. 6, a priority connection success display 601 indicates that the call between the priority connection service subscriber and the priority connection destination subscriber has succeeded, and the time at which the call succeeded is the priority connection success time. It is stored in the stamp 602.

FIG. 7 is a sequence diagram showing the flow of the priority connection service when the call is successful.

The originating subscriber is “service identification number”, “contract subscriber number” 201, “priority connection destination subscriber number” 20
When the originating exchange 112 makes a dial call (step 701), the originating exchange 112 makes an inquiry to the service control device 103 as to whether or not priority connection is permitted (step 702).

The service control unit 103 determines whether or not the priority connection is permitted (step 703), and returns a response indicating whether or not the priority connection is permitted to the originating exchange 112 (step 70).
4).

The originating exchange 112 sets a priority level based on the inquiry result shown in FIG.
(Step 705).

When the called subscriber answers (step 70)
6) A response is returned to the originating exchange (step 707).

When the originating exchange 112 detects a response, the service control unit 103 is notified of the priority connection success (step 708), and the service control unit 103 sets a priority connection success display 601 of the database 102 (step 709). , Then the priority connection success timestamp 60
2 is set to the current time (step 710), and a call between the calling subscriber and the called subscriber is started (step 71).
1).

FIG. 8 shows the priority connection service permission determining unit 10.
5 is a flowchart showing a process of determining whether or not a priority connection service call is successful within a predetermined time determined by the system; FIG. 304 ) is performed immediately before step 301).
Some of the processing flows after step 303 and step 305 are omitted.

To determine whether or not the call of the priority connection service is successful, first, a priority connection success indication 601 is determined (step 801), and if unsuccessful, a process of extracting the priority connection call number counter 203 is performed. Is done.

On the other hand, if successful, the priority connection success time stamp 602 is extracted (step 80).
2) It is determined whether or not a fixed time determined by the system has elapsed (step 803).

If it is determined that the predetermined time has elapsed, "unsuccessful" is set in the priority connection success display 601 (step 804), and the priority connection call number counter 203
Is set to "0" (step 805), and the process of extracting the priority connection call number counter 203 (step 306) is performed.

If it is determined in step 805 that the predetermined time has not elapsed, "non-permissible" is set in the determination result, the transmission switching center 112 is notified, and the process is terminated (step 80)
6).

As described above, for the priority connection service contractor who has made a call once, even if the priority connection call number counter 203 is set to the upper limit of the number of calls permitted to perform priority connection within a predetermined time set by the system. Even if the call does not exceed, by controlling not to allow the priority connection service within a certain period of time from the success of the call, it is possible to reduce calls to the incoming system congestion ground, The possibility of a successful call can be increased.

It is needless to say that the present embodiment can control each user identification number by providing a priority connection success indication and a priority connection success time stamp for each user identification number, as in FIG.

In each of the above embodiments, the "service identification number", "contracted subscriber number", "priority connection destination subscriber number", and "user identification number" dialed by the subscriber.
Are received by the exchange 112 and then the service control apparatus 103 is inquired about the permission judgment of the priority connection service. However, depending on the interface conditions between the exchange 112 and the service control apparatus 103, for example, When the exchange 112 receives the "service identification number", the exchange 112 notifies the service control apparatus 103, and the service control apparatus 103 instructs the exchange 112 to enter "contract subscriber number" and "priority connection destination subscriber number". , The effect of the present invention does not change even if a sequence of sequentially receiving “user identification numbers” is adopted.

Also, the system does not have a fixed upper limit for the number of calls for which priority connection is permitted within a certain period of time as a fixed value, but contracts a different upper limit for each contracted subscriber. The effect of the present invention does not change even if the number of calls is controlled within a predetermined time based on the value.

It is also possible to have a plurality of priority connection destination subscriber numbers. In the case of the database configuration of FIG.
The priority connection call number counter 203 and the first priority connection time stamp 20 correspond to each priority connection destination subscriber number 202.
5 and the database configuration shown in FIG. 5, and in the case of the database configuration of FIG. 5, similarly, the "user A priority connection call number counter 505" corresponding to the user identification number is changed to the "user D first connection time stamp 51
The data up to "2" can be easily realized by making a database configuration having a plurality of surfaces corresponding to the priority connection destination subscriber number 202.

Further, the originating exchange 102 determines whether or not the priority connection destination subscriber number dialed from the originating subscriber is a call to the outgoing connection restricted destination. The effect of the present invention does not change even if a method of inquiring of the service control apparatus 103 as to whether or not priority connection is permitted is employed.

[0082]

As described above, according to the present invention, the "contracted subscriber number" of the subscriber who has previously contracted the priority connection service in the telecommunications network and the priority call even if the outgoing connection is restricted. In order to register the "priority access subscriber number", the exchange accommodating the registered priority access destination subscriber number will be congested by the receiving system, and the outgoing exchange will restrict the outgoing connection. Even when the call is made, even if the calling telephone is a general telephone with a low priority level, dialing the contracted subscriber number and the priority connection destination subscriber number will result in a call from a high-priority public telephone. Connection processing can be performed at the same or higher priority level as the outgoing call, and the number of calls connected as priority calls within a unit time is limited. It is possible to reduce the force.

Further, according to the method of registering a plurality of “user identification numbers”, when a specific user uses the service up to an upper limit value which allows a priority connection within a predetermined time, another method is used. It is possible to avoid the problem that the user has to wait until a certain time elapses.

Further, an area for information indicating whether or not the priority connection has succeeded is provided, and for the priority connection service contractor who has been able to make a call once, even if the priority connection call number counter is set to a certain value determined by the system. Even if the upper limit of the number of calls for which priority connection is permitted within the time limit does not exceed the upper limit of the number of calls for which priority connection is permitted, by not allowing the priority connection service within a certain period of time from the success of the call, the call to the incoming congestion ground is prevented. It is possible to reduce the number of calls and increase the possibility of a successful call for a user who has not successfully made a call.

Therefore, it is extremely effective for confirming safety at the time of disaster such as an earthquake.
