Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a restricted ground identification device and, more particularly, to a connection restricted control method that can perform economical and simple traffic control in a traffic control system.

In the conventional connection restriction control system, the traffic control system connected to the exchanges of each telephone office in multiple closed number areas automatically detects the congestion status of each subscriber accommodated in each exchange, and detects abnormalities. In order to prevent calls from being received to the subscriber or tenant where congestion has occurred, the traffic control system connects the same subscriber or tenant to each exchange within the closed number area under the control of the traffic system. Send the regulation number. Each exchange receives this connection regulation number and writes it into the memory of the regulation ground identification device. At each exchange,
In order to restrict calls to destinations with connection restriction numbers, a restriction ground identification device identifies the relevant outgoing call, and the outgoing call is restricted at the originating station.

On the other hand, when making a call to a subscriber or tenant within a certain closed number area, even if it is a local call, a connection can be established even if the call is made by adding an area code. That is, even long-distance calls (with an added area code) may end up within the local office. Therefore, even if only local outgoing calls or long distance outgoing calls are restricted, calls can still be made using the other dial, and outgoing calls are not restricted.

Therefore, in the past, it was necessary to identify whether or not the connection restriction number was within the closed number area, and if it was within the closed number area, two restriction numbers were set, one for local calls and one for long distance calls. Ta. Therefore, two regulation identification circuits are required to regulate one subscriber or one tenant, which is uneconomical.

An object of the present invention is to provide a simple and economical connection regulation control method by reducing the required memory and the size of the collation and regulation judgment circuit by half by setting only one regulation number for the same subscriber or tenant. It is in.

According to the present invention, the above purpose is to receive connection restriction numbers sent from a traffic control system that is provided for each exchange and automatically detects the congestion state of each exchange, in order to restrict calls to connection restriction numbers. , in a restricted ground identification device that matches a selection signal from an originating subscriber accommodated in each exchange with the connection restriction number, a memory for setting and storing the connection restriction number, and a selection signal and the setting stored in the memory at the time of outgoing connection. The verification circuit receives the local number of the outgoing call within the closed number area from the common control device of the exchange, identifies that the call is a local outgoing call, and checks the closed number. means for adding the area code of the area, and by setting one restriction number in the memory for one restriction target, outgoing calls corresponding to the restriction number are restricted, and means for adding the area code in the memory. By setting a significant number for only the upper digits and leaving the remaining area code and city code parts blank, if a connection restriction number that includes multiple closed number areas is set, long-distance calls For calls, blank fields are not checked, only significant digits are checked, and for local calls, all digits of the added area code are checked against all digits of the set area code, including the blank parts. This can be achieved by having a means for restricting outgoing calls and not restricting outgoing calls within the local area.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a connection restriction control system according to an embodiment of the present invention. In Figure 1, 1
is a receiving unit that receives signals from a traffic control system that operates subscriber connection regulation, 2 is a restricted ground identification equipment (RCIE), 3 is a translator or marker of the common control section of the crossbar switch, and 4 is a
RCIE input section, 5 is scanning section, 6 is data editing section,
7 ₁ to 7 _o are memory for storing regulation numbers, 8 ₁ to 8 _o
9 is the area code addition part that is particularly required in the present invention; 10 is the RCIE
This is shown in the output section of

In Figure 1, the common control unit (TLR or SM)
When the RCIE 2 is activated, the RCIE 2 sequentially takes in information from the common control unit (TLR or SM) through the input unit 4 as scanned by the scanning unit 5. Then, the information edited by the data editing unit 6 is compared with the regulation number preset in the memory units 7 ₁ to 7 _o , and the regulation determining unit 8 ₁ to 8 _o determines whether or not to impose the regulation, and outputs the information. From section 10, the common control section (TLR
or SM) Give instructions to 3.

In this case, for 1 regulated subscriber or tenant,
Two types of activation are possible for outgoing calls from within a closed number area. One is to initiate a local call without an area code, and the other is to initiate a long-distance call with an area code. In order to regulate this using one regulation number, the number set in the memory section was designed to include the area code. Therefore, for calls without an area code, it is necessary to add the area code and perform verification. To do this, use the area code addition section 9.
has been established. If activation without area code is received from common control unit (TLR or SM) 3, input unit 4
This is identified by the area code addition unit 9, the area code addition unit 9 is activated, and the area code is imported from the area code addition unit 9 before the information from the common control unit (TLR or SM) 3 is imported. When the process is finished, information from the common control unit (TLR or SM) 3 is taken in. By performing this operation, it is possible to perform verification using the same information as information that includes an area code. However, in this case, as shown in Figure 7, the closed number area ABC
If the restriction number "A" that includes ADE and ADE is set, calls from the subscriber TELA in the closed number area ABC to the subscriber TELC in the closed number area ADE are of course restricted; number area ABC
Calls from TELA to TELB will also be regulated. The purpose of setting the restriction number A is originally to restrict calls to the area including the area code A, and in most cases there is no need to restrict the connection between TELA and TELB. For this reason, in the case of activation by a local outgoing call, we adopted a system in which regulation is performed on the condition that the added area code and regulation number completely match.
In Figure 7, closed number area ABC is the area code
This is a subscriber area with ABC, TELA is subscriber A in this area, and TELB is subscriber B in this area. closed number area
ADE is a subscriber area with area code ADE,
TELC is subscriber C in this area, closed number area FGH
is the subscriber area with area code FGH,
TELD is subscriber D within this area. Calls that originate from TELA and arrive at TELB are called calls that end within a closed number area (there are local calls and long-distance calls), and calls that originate from TELA and arrive at TELC or TELD. Such calls are called calls that do not end within the closed number area (long-distance calls).

Figures 2 to 5 show how to verify numbers using this method.
This will be explained using figures.

FIG. 2 shows a verification method in the case of activation by a local outgoing call. A is the information from the common control unit (TLR or SM), B is the added area code, C is the information after the area code is added, and D is the setting number. For example, if the regulation number "0abcdefghj" in the closed number area "abc" is set in advance, a verification method is shown when starting a local outgoing call "1defghj" thereafter. That is, add B to A in Figure 2, make it into a C, and compare it with D.

FIG. 3 shows a verification method in the case of activation by a long-distance call.

i is information from the common control unit (TLR or SM),
B is the setting number. In this case, Fig. 3 shows the verification method when starting a long-distance call "0abcdefghj" when the same number as in Fig. 2 is set.
Match A and B as they are.

FIG. 4 shows a verification method in the case of activation by a long-distance call when the regulation number "0a" that includes the closed number area "abc" is set. A is information from the common control unit (TLR or SM), B is the setting number. To explain this with reference to the configuration diagram of the present invention shown in FIG. 1, the data A arrives at the collation and determination section 8 from the common control section 3 via the input section 4, the scanning section 5, and the data editing section 6.
Note that T/L is information for identifying a local call or a long distance call, and A to J are connection destination numbers. B is set in advance in the memory unit 7', and the collation and regulation determination unit 8 collates and compares it with B. In this case, when the regulation number "0a" that includes the closed number area "abc" is set, the verification and regulation determination section 8 verifies A and B as they are when activated by the outgoing long distance call "0abcdefghj". Note that a blank field "" is set for regulation numbers (setting numbers) that do not require verification.
That is, the digits of setting numbers B to J are not verified. In other words, if only a matches, it is restricted. Regarding the regulation method, a regulation instruction is given to the common control unit 3 via the output unit 10.

FIG. 5 shows a verification method in the case of activation by a local call when the regulation number "0a" which includes the closed number area "abc" is set.

i is information from the common control unit (TLR or SM),
B is the additional area code, C is the information after the area code is added,
D is the setting number. In this case, Figure 5 shows a local outgoing call "1x" when the same number as in Figure 4 is set.
×××××” is the verification method at startup, which adds B to A, forms C, and matches it with D.
To explain with reference to the configuration diagram of the present invention shown in the figure, B is an area code that is additionally set by the area code addition section 9. Even if the call is within a closed number area, the area code corresponding to that area is added. D is set in advance in the memory section 7, and the comparison and regulation determination section 8 performs a comparison with C. In this case, since "0abc" and "0a〓〓" are compared, there is a mismatch and no regulation is performed.

Figure 6 shows the verification method when activated by a local call when the regulation number “0a” that includes the closed number area “abc” and the regulation number “0abcdefghj” in the closed number area “abc” are set at the same time. shows. A is the information from the common control unit (TLR or SM), B is the information after adding the area code "abc", and C and D are the setting numbers. In this case, FIG. 6 shows the verification method at the time of activation by a local call "1defghj" when the same number C as in FIG. 4 and the number D as in FIG. 3 are set.
Add the area code "abc" to A and make it into a B and match it with C and D. When checking with C, “0abc” and “0a〓〓” are checked, so there is a mismatch, but when checking with D, there is a match, so restrictions are applied. To explain this using the configuration diagram of the present invention shown in FIG. 1, the steps from A to B are the same as those shown in FIG.
Two regulation setting numbers C and D are set in advance, and the comparison and regulation determination section 8 performs two types of comparison comparisons: B and C and B and D.

As explained above, according to the present invention, by setting one restriction number, it is possible to restrict two types of outgoing calls to one subscriber or tenant, thereby halving the size of the memory and the verification and restriction determination section. , has economic effects. Further, since the number can be uniformly set without identifying whether the regulation number is within the self-closed number area or not, processing is simplified.
