  The present invention adds a new node called Proxy-MSC (Proxy-Mobile Switching Center) (corresponding to the proxy switch of the present invention) in a core network in circuit switching without changing the existing node. It is characterized by the ability to add new services.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
(First embodiment)
FIG. 1 is a conceptual diagram of a network in circuit switching.

  In the conceptual diagram of FIG. 1, configuration 1 shows the configuration of a conventional network, and configuration 2 shows the configuration of the network of the present invention.

  In the configuration 1 shown in FIG. 1, an HLR (Home Location Register) 50, an MSC (Mobile Switching Center) a41, a VLR (Visitor Location Register) a61, a BSS (Base Station Sub-System) a21, a BSS b22, MT (Mobile Terminal) 5 is provided.

  On the other hand, in the configuration 2 showing the present invention, a proxy-MSC 30 that is a new node is added to the conventional configuration 1 along with the VLR c63 like the conventional MSC a41 shown in the configuration 1. It has become.

  Thereby, as shown in the configuration 2, the present invention is characterized in that the Proxy-MSC 30 accompanied by the VLR c63 is added.

  Each subscriber is classified into a conventional MSC b42 accommodating user and a proxy-MSC 30 accommodating user of the present invention based on the subscriber profile held by the HLR 50.

  Here, in the subscriber profile, the mobile terminal MT5 or 10 mobile identification number, the location registration area number (LAI), which will be described later, and the contents for receiving various services are described as information related to the subscriber's terminal. The accommodation user of the conventional MSC b42 receives only the service related to the call, and the accommodation user of the Proxy-MSC 30 of the present invention can also receive a new service such as a short message.

  Further, a location registration area number (LAI), which will be described later, is described every time it is registered in the HLR 50 and is updated periodically.

  The present invention relates to a network configuration, and a service called a short message is a service that is not included in an existing network, and exemplifies a network configuration when providing as a new service.

  However, the service according to the present invention is an exemplification, and the service is not limited to a service related to a call or a short message shown in the first embodiment.

  In the configuration 1 showing the configuration of the conventional network, the location registration request and the transmission request of the MT5 in the area of the MSC a41 are transmitted to the MSC a41 via the BSS a21 or the BSS b22. .

  Here, the location registration request means that the MT 5 itself always communicates with the base station in order to inform the communication carrier which base station area it is in, and this communication is called location registration. The request is called a location registration request.

  The call origination request refers to requesting communication to start a telephone call or a short message.

  Therefore, in the configuration 1, when the MSC a41 receives the MT5 location registration request, the MSC a41 registers the location with the HLR 50, acquires the subscriber profile from the HLR 50, and stores it in the VLR a61. .

  As a result, the MSC a41 can register the position of the MT5 located in the area of the MSC a41 in the HLR 50 and provide a service related to the call based on the subscriber profile stored in the VLR a61.

  On the other hand, the Proxy-MSC 30 having the configuration 2 according to the present invention transmits a location registration request or a transmission request transmitted by the MT 10 via the BSS c23 or the BSS d24 at the time of location registration or transmission in the Proxy-MSC 30 area. All are transmitted to the Proxy-MSC 30 which is its own station.

  The Proxy-MSC 30 performs location registration with the HLR 50 in response to a location registration request by the MT 10, acquires a subscriber profile from the HLR 50, and determines a service applied to the subscriber by the subscriber profile.

  That is, when the subscriber is a Proxy-MSC accommodating user (a user who receives provision of a new service), call processing is executed by the Proxy-MSC 30, while the subscriber is an MSC accommodating user (providing an existing service). In the case of a user), the location registration request or the transmission request from the BSS c23 or the BSS d24 is directly transferred to the MSC b (corresponding to the exchange of the present invention) 42 through the newly provided Proxy-MSC 30. Then, call processing is executed in the MSC b42.

  In this way, for the MSC accommodating user, by executing the call processing with the existing MSC b42, the conventional service is provided from the MSC b42 via the Proxy-MSC 30, whereas the Proxy-MSC accommodating user is provided. By executing call processing with the Proxy-MSC 30 to a user, it is possible to provide a new service without changing the existing node.

  Accordingly, the BSS c23 or the BSS d24 is always connected to the Proxy-MSC 30 and relays a location registration request and a transmission request to the HLR 50 via the Proxy-MSC 30.

Note that the MT 10 receives radio waves from the BSS c23 and the BSS d24, and periodically makes a location registration request by associating an LAI described later with a mobile identification number.
(First embodiment)
FIG. 1 is a conceptual diagram of a network configuration. HLR50, VLR a61, VLR b62, VLR c63, MSC a41, MSC b42, BSS a21, BSS b22, BSS c23, BSS d24, MT5 and MT10 shown in configurations 1 and 2 are well known to those skilled in the art. Further, since it is not directly related to the present invention, its detailed description is omitted.

  The configuration 1 shown in FIG. 1 is a conventional network configuration, whereas the configuration 2 is a network configuration when a Proxy-MSC (Proxy-Mobile Switching Center) 30 is added.

  The embodiment of Configuration 1 will be described. The MSC a41 has a VLR a61. When MT5 is transmitted by a subscriber, a call request is notified to the MSC a41 via the BSS a21, and the subscription registered in the VLR a61. Call processing is performed by comparing the user profile with the LAI.

  On the other hand, the example of the configuration 2 will be described. The Proxy-MSC 30 holds an LAI (Local Area Identity) (a location registration area number accompanying a location registration request to be described later) different from the MSC b42. In cooperation with the HLR 50 and VLR c63, the subscriber profile has a function of determining whether the subscriber is an MSC-accommodating user or a Proxy-MSC accommodating user, which will be described later.

  Here, this LAI is the identification number of the location registration area assigned to each BSS in the reception area monitored by the Proxy-MSC 30, and when the MT 10 makes a call, the LAI and the mobile identification number of the MT 10 Reaches the Proxy-MSC 30 via the BSS c23 or BSS d24, and collates the LAI assigned to the MT 10 with the LAI described in the subscriber profile, so that which node (ie, Proxy-MSC 30 or It is determined whether the mobile terminal uses MSC b42).

  Specifically, the mobile identification number of MT10 and the LAI of BSS c23 or BSS d24 are encoded (associated) in MT10, registered in the HLR 50 by the location registration request, and recorded in the subscriber profile. The node (Proxy-MSC 30 or MSC b 42) to be applied is determined based on the location registration result returned to the Proxy-MSC 30 and the subscriber profile.

  Here, the node is a unit that is connected by a link and constitutes a network. Here, the node indicates the Proxy-MSC 30 or the MSC b42.

  If the subscriber is an MSC accommodating user, the signal is transferred to the MSC b42, and the subsequent call processing is performed at the MSC b42.

  In this case, the MSC b42 regards the Proxy-MSC 30 as one of the BSSs and registers it, so that the MSC b does not need to perform special processing associated with the addition of the Proxy-MSC 30.

  If the subscriber is a Proxy-MSC accommodating user, the subsequent call processing is executed in the Proxy-MSC 30.

  As described above, the Proxy-MSC 30 manages the location registration requests of all MTs 10, and by the subscriber profile acquired from the HLR 50, the proxy-MSC 30 can use a service such as a short message or a user who can use the service or a service related to a call. It is determined whether the user is an accommodated MSC b42 user.

  With the above functions, it is possible to provide either an existing service or a new service for each subscriber based on the subscriber profile.

  Further, when the Proxy-MSC does not exist in the area as in Configuration 1, both the MSC accommodating user and the Proxy-MSC accommodating user perform call processing with the existing MSC a41.

In the above embodiment, Proxy-MSC 30 and VLR c63 are handled as separate nodes. However, the function of VLR c63 may be built in Proxy-MSC 30 and handled as the same node.
(Description of operation)
In the first embodiment of the present invention, at the time of location registration (attachment) (the location registration is performed by the above-described location registration area number (ie, LAI), sometimes simply referred to as “attach”), the location registration ( Each operation at the time of transmission at the time of LA change (to be described later) will be described using the sequences shown in FIGS.

  First, a position registration (attach) processing sequence when the Proxy-MSC 30 exists in the area will be described with reference to FIGS. 2 and 3.

  FIG. 2 is a sequence showing a location registration (attach) process in a Proxy-MSC accommodating user.

  The MT 10 transmits a location registration request to the BSS 20 at the start of the attach operation (100 in FIG. 2). Upon receiving the location registration request, the BSS 20 transmits a location registration request to the Proxy-MSC 30 (101 in FIG. 2), and the Proxy-MSC 30 transmits a location registration instruction to the HLR 50 (102 in FIG. 2).

  The HLR 50 that has received the location registration instruction, after performing location registration, returns the result to the Proxy-MSC 30 as a location registration result notification (103 in FIG. 2) and also sends the subscriber profile.

  The Proxy-MSC 30 registers the location registration result and the subscriber profile as user information in the VLR associated with the own station (104 in FIG. 2), and then determines from the subscriber profile that the user is a proxy-MSC accommodating user ( 105 in FIG.

  Here, the subscriber profile describes contents that the MT 10 can receive a service, for example, describes that a service such as a short message can be received.

  In step 105, based on the contents described in the subscriber profile, it is determined whether the MT 10 is the accommodating user of the MSC 40 (corresponding to the MSC b42 in FIG. 1) or the Proxy-MSC 30.

  As a result, the Proxy-MSC 30 determines that it is a user accommodated by the Proxy-MSC 30 and a user of a new service based on the contents described in the subscriber profile.

  In this case, the Proxy-MSC 30 transmits a location registration response to the BSS 20 (106 in FIG. 2), and the BSS 20 that receives the response transmits a location registration response to the MT 10 (107 in FIG. 2). The attach process is complete.

  On the other hand, FIG. 3 is a sequence showing a location registration (attach) process in the MSC accommodating user.

  The MT 10 transmits a location registration request to the BSS 20 at the start of the attach operation (200 in FIG. 3). Upon receiving the location registration request, the BSS 20 transmits a location registration request to the Proxy-MSC 30 (201 in FIG. 3), and the Proxy-MSC 30 transmits a location registration instruction to the HLR 50 (202 in FIG. 3).

  The HLR 50 that has received the location registration instruction, after performing location registration, returns the result to the Proxy-MSC 30 as a location registration result notification (203 in FIG. 2) and sends the subscriber profile.

  The Proxy-MSC 30 registers the location registration result and the subscriber profile as user information in the VLR associated with the own station (204 in FIG. 3), and then determines from the subscriber profile that the user is an MSC accommodating user (FIG. 3). 205).

  Here, the subscriber profile describes contents that the MT 10 can receive services. For example, as a service related to a telephone, a call transfer service (transfers an incoming telephone call to another telephone), a calling number Only available services related to calls such as display / non-display and three-party calls are described.

  In step 205, based on the description contents of the subscriber profile, it is determined whether the MT 10 is an accommodation user of the MSC 40 (corresponding to the MSC b42 in FIG. 1) or the Proxy-MSC 30.

  Accordingly, the Proxy-MSC 30 determines that it is a user accommodated in the MSC 40 and a user of an existing service, based on the contents described in the subscriber profile.

  In this case, the Proxy-MSC 30 transmits a location registration request to the MSC 40 (206 in FIG. 3), and the MSC 40 receiving it transmits a location registration instruction to the HLR 50 (207 in FIG. 3).

  Since the location registration of the user has already been completed, the HLR 50 transmits a user information deletion request to the Proxy-MSC 30 that registered the user information in 204 of FIG. 3 (207 in FIG. 3).

  The Proxy-MSC 30 deletes the user information from the VLR (corresponding to the VLR c63 in FIG. 1) attached to the local station (209 in FIG. 3), and then transmits a user information deletion response to the HLR 50 (in FIG. 3). 210). The HLR 50 that has received the user information deletion response performs location registration, and returns the result as a location registration result notification to the MSC 40 (corresponding to the MSC b42 in FIG. 1) (211 in FIG. 3) and the subscriber. Send a Profile.

  The MSC 40 registers the location registration result and the subscriber profile as user information in the VLR (corresponding to VLR b62 in FIG. 1) (212 in FIG. 3), and then sends a location registration response (213 in FIG. 3) to the Proxy-MSC 30. Send.

  The Proxy-MSC 30 transmits a location registration response to the BSS 20 (214 in FIG. 3). Upon receiving the response, the BSS 20 transmits a location registration response to the MT 10 (215 in FIG. 3). Complete.

  When the Proxy-MSC 30 server does not exist in the area, the MSC 40 performs a conventional attach process.

  As described above, when the Proxy-MSC 30 corresponding to the new node receives a location registration request from the MT 10, the Proxy-MSC 30 instructs the HLR 50 to perform location registration, and corresponds to the VLR associated with the Proxy-MSC 30 (corresponding to the VLR c63 in FIG. 1). ) To register the location registration result and the subscriber profile.

  On the other hand, even if MT 10 corresponds to an existing node, the location registration result and the subscriber profile are registered in the VLR (corresponding to VLR b62 in FIG. 1) attached to the MSC 40 via the Proxy-MSC 30. Be able to.

  As described above, the present invention has the following effects.

  The first effect is that by adding a Proxy-MSC having a function as a proxy server, it is possible to add a new function that does not exist in the existing MSC without changing other nodes.

The second effect is that an MSC and a Proxy-MSC are installed in the same area, and an accommodation destination is set for each user, so that different services can be provided for each user.
(Second embodiment)
Next, a location registration (LA change) processing sequence using FIGS. 4 and 5 will be described.

  Here, the above-described LA (Location Area) change refers to changing the position registered in the HLR 50 by moving from the location where the MT 10 is located.

  Here, the LA is controlled by the Proxy-MSC 30 or the MSC 40 in the mobile communication network system, and a service area is configured by a plurality of LAs.

  4 and 5, New Proxy-MSC 30 and New MSC 40 are respectively Proxy-MSC (corresponding to Proxy-MSC 30 in FIG. 1) and MSC (corresponding to MSC b42 in FIG. 1) existing in the destination LA. .) The OLD MSC and the OLD Proxy-MSC 50 are MSC or Proxy-MSC in which the MT 10 is accommodated before movement.

  FIG. 4 is a sequence showing a location registration (LA change) process in a Proxy MSC accommodating user.

  When the area movement is performed in the state where the position registration (attachment) is performed, the MT 10 transmits a position registration request to the BSS 20 (301 in FIG. 4). When the BSS 20 that has received the location registration request transmits a location registration request to the New Proxy-MSC 30 (302 in FIG. 4), the New Proxy-MSC 30 includes the mobile identification number of the MT 10 and the LAI (the aforementioned location registration area number). After specifying the Old MSC (or Old Proxy-MSC) 45 before LA change from the server, request an authentication information (303 in FIG. 4), and after receiving the authentication information response from the Old MSC (or Old Proxy-MSC) 45 (304 in FIG. 4), the New Proxy-MSC 30 issues a location registration instruction to the HLR 50 (305 in FIG. 4).

  In this case, the MT 10 is detected when the LA monitored by the Proxy-MSC 30 in FIG. 1 and the Proxy-MSC (not shown) monitoring the adjacent LA form a network, so that the LAI changes the area. Also, the movement of MT10 can be recognized.

  Since the location registration of the user has already been completed, the HLR 50 transmits a user information deletion request to the Old MSC (or Old Proxy-MSC) 45 (306 in FIG. 4), and then the Old MSC (or Old Proxy-MSC). ) 45 deletes the user information (307 in FIG. 4) from the VLR (VLR b62 or VLR c63 in FIG. 1) attached to the own station, and then returns a user information deletion response to the HLR 50. (308 in FIG. 4).

  After performing the location registration, the HLR 50 returns the result to the New Proxy-MSC 30 as a location registration result notification (309 in FIG. 4) and sends the subscriber profile.

  The New Proxy-MSC 30 registers the location registration result and the subscriber profile as user information in the VLR (corresponding to the VLR c63 in FIG. 1) attached to the own station (310 in FIG. 4), and then from the subscriber profile. It is determined that the user is a Proxy-MSC accommodating user (311 in FIG. 4).

  Here, the subscriber profile describes contents that the MT 10 can receive a service, for example, describes that a service such as a short message can be received.

  In step 311, based on the contents described in the subscriber profile, it is determined whether the MT 10 is an accommodating user of the MSC 40 (corresponding to the MSC b42 in FIG. 1) or the Proxy-MSC 30.

  As a result, the Proxy-MSC 30 determines that it is a user accommodated by the Proxy-MSC 30 and a user of a new service based on the contents described in the subscriber profile.

  In this case, the New Proxy-MSC 30 transmits a location registration response to the BSS 20 (312 in FIG. 4), and the BSS 20 that receives the response transmits a location registration response to the MT 10 (313 in FIG. 4). The LA change process is completed.

  On the other hand, FIG. 5 is a sequence showing a location registration (LA change) process in the MSC accommodating user.

  In the New Proxy-MSC 30, a sequence (from 401 in FIG. 5 to FIG. 5) until the location registration result and the subscriber profile are registered as user information in the VLR (corresponding to VLR c 63 in FIG. 1) attached to the own station. 410) is the same as the sequence in FIG. 4 (301 in FIG. 4 to 310 in FIG. 4), and thus the description thereof is omitted.

  When the New Proxy-MSC 30 determines that it is an MSC-accommodating user from the subscriber profile (411 in FIG. 5), it transmits a location registration request to the New MSC 40 (412 in FIG. 5).

  Here, the subscriber profile describes contents that the MT 10 can receive services. For example, as a service related to a telephone, a call transfer service (transfers an incoming telephone call to another telephone), a calling number Only available services related to calls such as display / non-display and three-party calls are described.

  In step 411, based on the description contents of the subscriber profile, it is determined whether the MT 10 is an accommodating user of the MSC 40 (corresponding to the MSC b42 in FIG. 1) or the Proxy-MSC 30.

  As a result, the Proxy-MSC 30 determines that it is a user accommodated in the MSC 40 and a user of an existing service, based on the contents described in the subscriber profile.

  The New MSC 40 makes an authentication information request to the New Proxy-MSC 30 (413 in FIG. 5) and receives an authentication information response from the New Proxy-MSC 30 (414 in FIG. 5), and then issues a location registration instruction to the HLR 50. Perform (415 in FIG. 5).

  Since the HLR 50 has already completed the location registration of the user, when the user information deletion request is transmitted to the New Proxy-MSC 30 (416 in FIG. 5), the New Proxy-MSC 30 transmits the VLR associated with its own station (see FIG. 5). After the user information is deleted (417 in FIG. 5), a user information deletion response is returned to the HLR 50 (418 in FIG. 5).

  After performing the location registration, the HLR 50 returns the result as a location registration result notification to the New MSC 40 (419 in FIG. 5) and sends the subscriber profile.

  The New MSC 40 registers the location registration result and the subscriber profile as user information in the VLR (corresponding to the VLR b62 in FIG. 1) attached to the own station (420 in FIG. 5), and then stores the location in the New Proxy-MSC 30. A registration response is transmitted (421 in FIG. 5).

  The New Proxy-MSC 30 transmits a location registration response to the BSS 20 (422 in FIG. 5), and the BSS 20 that receives it transmits a location registration response to the MT 10 (423 in FIG. 5). Processing is complete.

  Therefore, when the Proxy-MSC 30 does not exist in the movement destination area, the conventional location registration (LA change) process is performed.

  As described above, even when the location registration is changed, the New Proxy-MSC 30 corresponding to the new node has the location information in the VLR (corresponding to the VLR c63 in FIG. 1) attached to the New Proxy-MSC 30. On the other hand, even if it corresponds to an existing node, the VLR associated with the New MSC 40 after the position change (corresponding to VLR b62 in FIG. 1) via the New Proxy-MSC 30. The location information can be registered in the.

Accordingly, in the present invention, even if the location registration is changed, the network can be switched appropriately, and the service can be provided without changing the core network.
(Third embodiment)
Next, a transmission sequence will be described with reference to FIGS.

  FIG. 6 is a sequence showing a calling process in the Proxy-MSC accommodating user.

  In FIG. 6, the MT 10 transmits a call request to the BSS 20 at the time of call (501 in FIG. 6). Upon receiving the call request, the BSS 20 transmits the call request to the Proxy-MSC 30 (502 in FIG. 6). Therefore, it is determined that the type is Proxy-MSC (503 in FIG. 6).

  At this time, the presence / absence of the subscriber profile is determined by comparing the LAI sent by the transmission of the MT 10 with the LAI described in the subscriber profile to determine whether or not they have the same area number.

  Here, since the LAI described in the subscriber profile is the same as the LAI sent by the transmission of MT10, it is determined that there is a subscriber profile corresponding to MT10.

  In this case, the proxy-MSC 30 continuously performs call processing for outgoing calls (504 in FIG. 6), thereby completing a series of outgoing call processing.

  FIG. 7 is a sequence showing a calling process in the MSC accommodating user.

  In FIG. 7, the MT 10 transmits a call request to the BSS 20 at the time of call (601 in FIG. 7). Upon receiving the call request, the BSS 20 transmits a call request to the Proxy-MSC 30 (602 in FIG. 7). Since there is no subscriber profile, it is determined that the type is MSC (603 in FIG. 7).

  At this time, the presence / absence of the subscriber profile is determined based on whether or not the same area number is obtained by comparing the LAI sent by the transmission of MT 10 with the LAI described in the subscriber profile in the same manner as described above. The

  Here, since the LAI described in the subscriber profile and the LAI sent by the transmission of MT10 are different, it is determined that there is no subscriber profile corresponding to MT10.

  In this case, the Proxy-MSC 30 transmits a call request to the MSC 40 (604 in FIG. 7). By executing the call processing for the outgoing call in the MSC 40 (605 in FIG. 7), a series of outgoing call processing is completed.

  As described above, when the location registration is completed in the Proxy-MSC 30 or the MSC 40, the subscriber profile exists in the VLR (corresponding to the VLR b62 or VLR c63 in FIG. 1) associated with the station. Thus, by always accessing the Proxy-MSC 30 that manages the new node, it is not necessary to change the network configuration of the existing node, and it is registered in the VLR (corresponding to the VLR b62 or VLR c63 in FIG. 1). By comparing the subscriber profile with the LAI of the MT 10, it is possible to perform a calling process from the Proxy-MSC 30 or the MSC 40 according to the service.

  Since the operation at the time of incoming call is not different from the conventional operation, it will be omitted.

  In the first embodiment according to the present invention, the case where the new service of Proxy-MSC 30 is applied to a short message has been described. However, the present invention is not limited to this, and the same service as MSC 40 is implemented. Or other different types of new services.

  In this case, by implementing a service similar to the MSC 40, the existing service can be enhanced and the LA can be expanded. Furthermore, since services similar to those of the MSC 40 can be provided together by new services, the provided services can be expanded.

  The network shown in the first embodiment of the present invention is not limited to the MSC network using the MSC 40 or the like, but is an IP (Internet) configured by an exchange such as a SGSN (Serving GPRS Switching Node). Protocol) network, and any form that can configure the network is acceptable.

  In this case, the node to be added may be switched by determining whether to provide a new service or to provide an existing service. By making RA (Routing Area) corresponding to LA correspond to an area change, A new service corresponding to the IP network can be provided.
