Description

  The present invention relates to a call connection control system, a home location register, an exchange, and a mobile terminal device in a mobile communication service in which a plurality of telephone numbers are assigned to a single mobile terminal device.

If you have signed up for multiple mobile terminal devices in the same household, for example, your father will use your mobile terminal device only on weekdays, while your daughter will use your mobile terminal device only on holidays, There is a proposal to deal with a situation in which the basic fee is uneconomical without being reduced or exempted (see, for example, Patent Document 1).
Patent Document 1 can reduce the burden on both the telecommunications carrier side and the subscriber side when the subscriber has a usage contract for a plurality of mobile terminal devices to which different telephone numbers are assigned. Various communication systems have been proposed.

This Patent Document 1 includes an alternative communication permission unit that enables a plurality of mobile terminal devices to selectively communicate with each other. It is disclosed that a process of switching a mobile terminal device capable of communication is executed only when it is received from a mobile terminal device capable of communication.
Since only one of the mobile terminal devices can be selectively communicated, the congestion of the line can be suppressed, and therefore the capital investment cost on the operator side can be reduced. As a result, it is said that the basic charge when one subscriber contracts with a plurality of mobile terminal devices can be set at a relatively low charge.

In addition, when multiple subscriber numbers are used with the same mobile terminal device, it is possible to use a phone number with a different service content in a normal mobile terminal device, and it is possible to make a call from any phone number easily. There is also a proposal related to a communication system of a mobile terminal device (for example, see Patent Document 2).
In Patent Document 2, a main telephone number and a sub telephone number are registered in a database in advance, and a plurality of telephone numbers with different service contracts can be used properly by appropriately changing outgoing registration, and the mobile terminal device Does not require special functions. Furthermore, it is supposed that the charging condition and the incoming condition can be set to desired conditions.

Furthermore, in a mobile phone communication system that constantly assigns and operates a plurality of telephone numbers to a single mobile terminal device, if there is a change in the use of a plurality of telephone numbers, it is possible to appropriately respond to this change. A mobile communication system has been proposed (see, for example, Patent Document 3).
In Patent Document 3, a base station manages outgoing and incoming calls by a mobile terminal device using a mobile communication system that communicates with the mobile terminal device via a single wireless interface. It respond | corresponds to the change regarding proper use.

Currently, in 3GPP (3rd Generation Partnership Project), which is a standard for mobile communication systems, one IMSI (International Mobile User Identity) recorded in a SIM (Subscriber Identification Module) of one mobile terminal device is used. It is stipulated that multiple telephone numbers can be registered.
When a plurality of telephone numbers are registered in one mobile terminal device in accordance with the above 3GPP regulations, when a telephone number other than the telephone number permitted for packet connection is used. There is also a proposal regarding a communication control method capable of performing packet communication by connecting to a service provider (see, for example, Patent Document 4).

  In Patent Document 4, when the telephone number permitted by the service provider for packet connection with the mobile terminal device is different from the notification number of the mobile terminal device, the control node obtains the telephone number from the roaming communication control device. By doing so, it is possible to perform packet communication even for a service provider that permits packet connection only to one telephone number among a plurality of telephone numbers registered in one mobile station. Technology is disclosed.

It is a block diagram showing the mobile terminal device as one embodiment of this invention.

Hereinafter, the present invention will be clarified by describing embodiments of the present invention in detail with reference to the drawings.
(Configuration of call connection control system)
FIG. 1 is a conceptual diagram showing the configuration of a call connection control system as one embodiment of the present invention. In this conceptual diagram, the infrastructure that is not directly related to the elements constituting the present invention is not shown. As is well known, the establishment of mobile communication involves the intervention of a base station or other infrastructure that is responsible for signal transmission in the radio section, but these points that are obvious to those skilled in the art will not be specifically mentioned below.

  1, the call connection control system 100 includes a first home location register (hereinafter referred to as a first HLR) 110, a second home location register (hereinafter referred to as a second HLR) 120, A first exchange (a node including a function of the exchange and hereinafter referred to as a first MSC / VLR) 130, and a second exchange (a node including a function of the exchange and hereinafter referred to as a second MSC / VLR). 140 is included.

The first HLR 110 and the second HLR 120 in the call connection control system 100 are connected to the customer management system 101, and data on various items related to the subscriber contract are input from the customer management system 101.
The first HLR 110 is installed corresponding to a first telephone number among a plurality of telephone numbers associated with a mobile terminal apparatus (hereinafter, referred to as first mobile terminal apparatus as appropriate) 151. In the registration information holding unit 111, data representing the other-device independent communication mode license agreement 112, the subscriber profile 113, and the corresponding telephone number (first telephone number) 114 are registered.

The registration information holding unit 111 further includes an IMSI holding unit 115, which holds the subscriber's IMSI (International Mobile Subscriber Identity) based on the other-device independent communication mode license agreement 112.
The second HLR 120 is installed corresponding to the second telephone number among the plurality of telephone numbers associated with the mobile terminal device 151. In the registration information holding unit 121, data representing the other-device independent communication mode license agreement 122, the subscriber profile 123, and the corresponding telephone number (second telephone number) 124 are registered.

In this example, a virtual IMSI holding unit 125 is further set in the registration information holding unit 121 described above, and a virtual IMSI that is a virtual subscriber IMSI based on the other-device independent communication mode license agreement 122 is set here. Is retained. The virtual IMSI is set from the above-described customer management system 101 when the other device independent communication mode license agreement is concluded.
Here, the other-device independent communication mode license agreement means that a plurality of telephone numbers are associated with one corresponding mobile terminal device and one of the plurality of telephone numbers is used by the one mobile terminal device ( For example, it is a contract or information for permitting another device independent communication mode in which another phone number (for example, the second phone number) different from the first phone number is used independently by the other mobile terminal device.

  On the other hand, the first MSC / VLR 130 includes a call connection control unit 131. The call connection control unit 131 uses the other mobile terminal device 152 based on the other device independent communication mode license agreement 112 when the other device independent communication mode is selected from the corresponding mobile terminal device 151. The call connection control relating to the number (second telephone number) is executed independently of the call connection control relating to one telephone number (first telephone number) used in the one mobile terminal device 151.

  In the call connection control system 100 of this example, the second MSC / VLR 140 has the same configuration as the first MSC / VLR 130 described above. That is, the call connection control unit 141 includes the other mobile terminal based on the other device independent communication mode license agreement when the other device independent communication mode is selected in the corresponding mobile terminal device. The call connection control related to the other telephone number used in the apparatus is executed independently of the call connection control related to the one telephone number used in the one mobile terminal apparatus.

In the above-described configuration, when the first mobile terminal device 151 is located at a point where communication is performed due to the involvement of the first MSC / VLR 130, when making a call to the mobile terminal device (not shown) of another subscriber Then, call connection (outgoing) is performed via the first MSC / VLR 130 and the known GMSC (Gateway Mobile Switching Center) 160. In FIG. 1, this path is indicated by a solid arrow.
Further, on the same assumption as described above, when there is an incoming call from another subscriber to the first mobile terminal device 151, the call passes through the GMSC 160 and then passes through the first MSC / VLR 130 with reference to the first HLR 110. Connection (incoming) is made. In FIG. 1, this path is indicated by a broken arrow.

(Operation of call connection control system)
Next, the operation of the call connection control system of FIG. 1 will be described with reference to a sequence chart. In each of the following sequence charts, the first mobile terminal apparatus 151 is represented as a first UE, the second mobile terminal apparatus 152 is represented as a second UE, and in the description performed with reference to these sequence charts, the first UE and the first UE 2UE name is used.
FIG. 2 is a sequence chart showing an operation in the case where the first mobile terminal apparatus in FIG. 1 is set to a multiple number mode in which communication can be performed using any predetermined number of telephone numbers. Here, it is assumed that the first HLR and the second HLR already hold the contract in the above-described multi-number mode (the contract information).

Based on a user operation on the first UE, a mode switching signal to be set to the multi-number mode is sent from the first UE to the second HLR via the first MSC / VLR (step S201).
The second HLR receives the signal in step S202 and switches the setting to the above-described multi-number mode (step S203). Then, a mode switching permission response for permitting switching to the multi-number mode is returned to the first UE via the first MSC / VLR (step S204).
1st UE receives the response of step S205, and transfers to the state which operate | moves in the above-mentioned multiple number mode. When the transition is completed, the first UE can make and receive calls using either the first telephone number or the second telephone number.

On the other hand, FIG. 3 is a sequence chart showing an operation when the second mobile terminal apparatus (second UE) in FIG. 1 is set to the other-device independent communication mode.
As described above, the other-device independent communication mode refers to one telephone number that is associated with one corresponding mobile terminal apparatus and that is used by the one mobile terminal apparatus among the plurality of telephone numbers. This is an operation mode in which another telephone number (for example, the second telephone number) different from (for example, the first telephone number) is used independently by the other mobile terminal device.
Here, it is assumed that the first HLR and the second HLR already hold the contract of the other-device independent communication mode (the contract information).

A mode switching signal to the other-device independent communication mode is issued from the first UE (step S301), and transmitted to the second HLR via the first MSC / VLR (step S302).
When the second HLR receives the mode switching signal to the other device independent communication mode in step S302, the second HLR itself switches the setting to the other device independent communication mode (step S303).
Then, another device independent communication mode permission response for permitting switching to the other device independent communication mode is issued to the first MSC / VLR (step S304), and the other device independent communication mode permission response is sent to the first MSC / VLR. It is emitted toward 2MSC / VLR (step S305).

The first MSC / VLR transfers the other-device independent communication mode permission response received in step S304 to the first UE (step S306).
The second MSC / VLR forwards the other-device independent communication mode permission response received in step S305 to the second UE (step S307).
Thus, the first UE can make and receive calls using the first telephone number, and the second UE can make and receive calls using the second telephone number independently of the first UE. That is, the first UE and the second UE can perform transmission / reception in the other-device independent communication mode.

  On the other hand, FIG. 4 is a sequence chart showing an operation when performing location registration in a state where the first mobile terminal apparatus (first UE) in FIG. 1 is set to the multi-number mode. In the case of FIG. 4 as well, as described above with reference to FIG. 2, it is assumed that the first HLR and the second HLR already hold the above-described multi-number mode contract (the contract information). Further, in the following sequence chart, for convenience, the first telephone number in FIG. 1 is referred to as “A number” and the second telephone number is referred to as “B number”.

When a terminal connection / location registration request is transmitted from the first UE to the first MSC / VLR (step S401), the first MSC / VLR that has received the request transmits a location registration request toward the first HLR (step S402).
In response to the location registration request in step S402, the first HLR determines whether or not a regular contract in the multiple number mode is concluded (step S403).
When it is confirmed in step S403 that a regular contract is concluded, the subscriber profile is downloaded to the first MSC / VLR (step S404). In this step S404, the IMSI of the A number, the IMSI of the B number, the A number (that is, the first telephone number), and the code indicating that the regular contract of the multi-number mode is concluded from the first HLR to the first MSC. / VLR.

In response to the transfer of data (code) in step S404, the first MSC / VLR holds the IMSI of the A number, the A number (that is, the first telephone number), the profile, and the like (step S405).
Based on the data (code) held in step S405, the first MSC / VLR determines that location registration relating to the B number (that is, the second telephone number) is necessary in light of the contract information (step S406).
Based on the determination in step S406, the first MSC / VLR is associated with the second HLR with a BSI IMSI and a code indicating that a legitimate contract for the B number (ie, the second telephone number) has been concluded. Thus, a location registration request is issued (step S407).

The second HLR receives the location registration request in step S407 and performs mode determination (step S408).
If it is determined in step S408 that the multi-number mode is selected, the subscriber profile is downloaded to the first MSC / VLR (step S409). In step S409, the IMSI of the B number, the B number (that is, the second telephone number), and the code indicating that the regular contract is concluded are transmitted from the second HLR to the first MSC / VLR.

In response to the transfer of data (code) in step S409, the first MSC / VLR holds the B number IMSI, the B number (that is, the second telephone number), the profile, and the like (step S410).
As a result, through steps S405 and S410, the first MSC / VLR retains the IMSI, phone number, profile, etc. for both the A and B phone numbers, and can make and receive calls with any phone number. .

The first MSC / VLR receives the transfer of data (code) in step S409, and holds these data in step S410, and issues a download completion response to the first HLR (step S411).
In response to the response in step S411, the first HLR returns a location registration update completion response to the first MSC / VLR (step S412).
In response to the response of step S412, the first MSC / VLR transfers a location registration update completion response to the first UE (step S413).

FIG. 5 is a sequence chart showing an operation when performing location registration in a state where the first mobile terminal apparatus (first UE) in FIG. 1 is set to the single number mode. Here, the single number mode is a mode in which a predetermined one telephone number is used in one mobile terminal device.
When a terminal connection / location registration request is transmitted from the first UE to the first MSC / VLR (step S501), the first MSC / VLR that has received the request transmits a location registration request toward the first HLR (step S502).

In response to the location registration request in step S502, the first HLR determines whether or not a regular contract in the single number mode has been concluded (step S503).
When it is confirmed in step S503 that a regular contract is concluded, the subscriber profile is downloaded to the first MSC / VLR (step S504). In this step S504, the IMSI of the A number, the IMSI of the B number, the A number (that is, the first telephone number), and a code indicating that the regular contract is concluded are transmitted from the first HLR to the first MSC / VLR. Is done.

In response to the transfer of data (code) in step S504, the first MSC / VLR holds the IMSI of the A number, the A number (that is, the first telephone number), the profile, and the like (step S505).
Based on the data (code) held in step S505, the first MSC / VLR determines that location registration relating to the B number (that is, the second telephone number) is necessary in light of the contract information (step S506).
Based on the determination in step S506, the first MSC / VLR is associated with the second HLR with a BSI IMSI and a code indicating that a legitimate contract for the B number (ie, the second telephone number) has been concluded. The location registration request is issued (step S507).

The second HLR performs mode determination in response to the location registration request in step S507 (step S508).
If it is determined in step S508 that the single number mode is selected, the subscriber profile is downloaded to the first MSC / VLR (step S509). However, when the single number mode is selected in the first UE, in this step S509, null data (indicated as “Null” in the figure) simply imitating the format of the profile data is changed from the second HLR to the first MSC / VLR. Sent.

Even if the data (code) is transferred in step S509, the first MSC / VLR is in the single number mode, so the first MSC / VLR displays the B number IMSI, the B number (that is, the second telephone number), the profile, and the like. The holding is not performed (step S510... Virtual step shown by broken lines).
As a result, even after passing through step S505 and step S510 (virtual step), the first MSC / VLR retains the IMSI, telephone number, profile, etc. only for the A number, and can make and receive calls only with the A number. is there.

When the first MSC / VLR receives the transfer of data (code) in step S509, the first MSC / VLR issues a download completion response to the first HLR (step S511).
In response to the response in step S511, the first HLR returns a location registration update completion response to the first MSC / VLR (step S512).
In response to the response in step S512, the first MSC / VLR transfers a location registration update completion response to the first UE (step S513).

FIG. 6 is a sequence chart showing a situation where location registration using the second mobile terminal device (second UE) is not performed in a state where the first mobile terminal device (first UE) is set to the multi-number mode. It is.
As illustrated in FIG. 6, it is assumed that the “multi-number mode” is selected in the first UE. In this state, when a terminal connection / location registration request is transmitted from the second UE to the second MSC / VLR. The second MSC / VLR that has received this (Step S601) transmits a location registration request to the second HLR (Step S602).

In response to the location registration request in step S602, the second HLR determines whether or not a regular contract in the multi-number mode has been concluded (step S603).
When it is confirmed in step S603 that a regular contract has been concluded, the subscriber profile is downloaded to the second MSC / VLR (step S604). However, when the multiple number mode is selected in the first UE, in this step S604, null data (indicated as “Null” in the figure) that simply imitates the format is transmitted from the second HLR to the first MSC / VLR.

Even if the data (null data) is transferred in step S604, if the multi-number mode is selected for the first UE, the second MSC / VLR does not hold the profile (step S605: virtual illustrated in broken line). Step). Therefore, when the first UE is in the multi-number mode, transmission / reception on the second UE side is not possible.
FIG. 7 shows that when the first mobile terminal device (first UE) is set to the other-device independent communication mode, the second mobile terminal device (second UE) independently registers the location using another telephone number. It is a sequence chart showing the condition where is performed.

As shown in FIG. 7, it is assumed that the “other device independent communication mode” is selected in the first UE, and in this state, the terminal connection / location registration request is transmitted from the second UE to the second MSC / VLR. Then (Step S701), the second MSC / VLR that has received this transmits a location registration request to the second HLR (Step S702).
In response to the location registration request in step S702, the second HLR determines whether or not a regular contract in the other-device independent communication mode is concluded (step S703).

When it is confirmed in step S703 that the regular contract is concluded, the subscriber profile is downloaded to the second MSC / VLR (step S704). In step S704, the IMSI of the B number, the B number (that is, the second telephone number), and a code indicating that the regular contract is concluded are transmitted from the second HLR to the second MSC / VLR.
In response to the transfer of data (code) in step S704, the second MSC / VLR holds the BSI IMSI, the B number (that is, the second telephone number), the profile, and the like (step S705). Accordingly, the second UE side can perform transmission / reception using the B number independently of the first UE. That is, the other device independent communication mode is realized.
