Abstract

A roaming mobile communication system in which a roaming incoming call to a moving subscriber can be connected to a mobile communication network adopting a different roaming number assigning system. In order to connect an incoming call to a moving subscriber, the mobile communication system connects a first mobile communication network to a second mobile communication network through an interwork location register. The first mobile communication network is the network to which the in-area location register of the in-area network, where the moving subscriber exists when the incoming call is connected to the moving subscriber, allocates temporarily a roaming number. The second mobile communication network is the network to which the gate location register of the in-area network, where the moving subscriber exists when the location of the moving subscriber is registered, allocates temporarily a roaming number. The interwork location register is used for registering the location of the moving subscriber who is roaming and for allocating the roaming number when the incoming call is connected.

Description

TECHNICAL FIELD The present invention relates to a single-porting mobile communication system for performing single-porting between mobile communication networks. And methods. 2. Description of the Related Art In mobile communication, which has been spreading in recent years, multiple carriers have been using systems such as NTT, J-TACS, N-TACS, GSM, and PDC. Different communication methods are adopted respectively. Then, when the mobile subscriber moves to such a service provider of another carrier, it is possible to make and receive calls from this different service area. As a service, so-called roaming is available. A roaming mobile subscriber can make an incoming connection wherever it is. Are known . In other words, the method in which the visited location register of the visited network temporarily assigns a roaming number at the time of incoming connection, and the location of the gateway in the visited network This is a method in which the register assigns a roaming number when registering a location.

First, the former of the above-mentioned conventionally known methods, This section describes the method by which the location register in the area network temporarily assigns a mouthing number when an incoming connection is established. Fig. 1 shows the configuration of a mobile communication system for explaining this method, and Figs. 2 and 3 show the control method. In each of these figures, the VMSC (Visited Mobile Switching Center) is the serving exchange, the VLR (Visited Location Register) is the serving location register, and the HLR (Home Location Register). Is a home location register, and GMSC (Gateway Mobile Switching Center) is a gateway exchange. Solid lines indicate communication lines, and broken lines indicate control lines.

As shown in Fig. 2, when a mobile subscriber moves to a control area of a serving switching center VMSC2 (1), a location registration request is issued.

Step (2) is performed for the serving switching center VMSC2. Upon receiving the location registration request (2), the serving switching center VMSC2 sends a location registration request to the serving location register VLR2.

Execute (3). Upon receiving the location registration request (3), the located location register VLR2 usually searches for the information of the mobile subscriber and updates the location information. However, the current location register VLR 2 does not store the information of the subscriber who has requested location registration for the first time, and therefore stores the information of that subscriber. And secure the location information of the subscriber. In addition, the visited location register VLR 2 is used for the home location register HLR, which constantly stores the subscriber information of the subscriber. The exchange number of the serving switching center VMSC 2 and the serving location The identification number of the star VLR 2 is notified (4). The home location register HLR stores the identification number of the serving exchange and the identification number of the serving location register (5) o

Next, when an incoming call is made to the mobile subscriber, as shown in Figure 3, the incoming call is called an IAM (Initial Address Message) according to the subscriber's subscriber number, as shown in Figure 3. Then, it is routed to the gateway exchange GMSC of the mobile communication network to which the subscriber subscribes. The gateway switching center GMSC requests the home location register HLR for information for routing the mobile subscriber's incoming call (2). Upon receiving the routing information request (2) from the gateway switching center GMSC, the home location register HLR searches for the information of the subscriber, and searches for the existing exchange. Know the identification number of the station VMSC 2 and the identification number of the location register VLR 2 in the service area. In addition, the home location register HLR sends the subscriber's incoming call to the serving location register VLR2. Request the assignment of a roaming number for routing (3). Upon receiving the oral number assignment request (3), the location location evening VLR 2 temporarily roams the subscriber. Assign a number (4) and use the home location register.

Return to HLR (5) 0 Home Location Register

The HLR notifies the roaming number to the gateway exchange GMSC (6). The gateway exchange GMSC uses the roaming number Therefore, the incoming call is routed to the serving switching center VMSC 2 as IAM (7).

Next, the latter method, which is known from the past, is a method in which the location register of the visited network assigns a roaming number at the time of location registration. Is explained. Fig. 4 shows the configuration of a mobile communication system for explaining this method, and Figs. 5 and 6 show the control method. In each of these figures, the GLR (Gateway Location Register) is the relevant P location register.

In addition, as long as the mobile subscriber moves within the mobile communication network to which the subscriber subscribes, the location information of the subscriber is updated in each home location register HLR. In order for mobile subscribers to move to and communicate with a mobile communications network to which the mobile subscriber has not subscribed, the mobile subscriber must first roam with that mobile communications network. You need to make a contract.

As shown in FIG. 5, when the mobile subscriber 60 moves to the mobile communication network 11 with the roaming contract (1), the mobile subscriber network 60 is located in the mobile communication network 11. A position registration request is made to the exchange VMSC 44 (2). Upon receiving the location registration request (2), the serving exchange VMSC 44 executes the location registration request (3) to the gateway location register GLR31. Upon receiving the location registration request (3), the gateway location register GLR 31 does not store the information of the subscriber who has requested location registration for the first time. Secures an area to store the information of the subscriber, and talks to that subscriber Assign a number (4). In addition, the gateway location register GLR 31 is connected to a home location-location register HLR 20 that constantly stores the subscriber information of the subscriber. On the other hand, the roaming number is notified (5), and the home location register HLR 20 stores the roaming number (6).

Next, when an incoming call is made to the mobile subscriber 60, as shown in Fig. 6, according to the subscriber's subscriber number, the incoming call is made as an IAM and the incoming It is routed to the gateway exchange GMSC 50 of the mobile communication network 10 to which the subscriber subscribes (1). The gateway switching center GMSC 50 requests the home location register HLR 20 for information to route the mobile subscriber 60's incoming call. (2) When the home location register HLR 20 receives the routing information request (2) from the gateway exchange GMSC 50, the home location register HLR 20 receives the request. The subscriber information is searched, and if the roaming number is stored, the roaming number is returned to the gateway exchange GMSC 50 (3). According to this roaming number, the gateway exchange GMSC 50 sends an incoming call to the gateway exchange GMSC 51 of the mobile communication network 11 in which the subscriber is located as an IAM. Perform routing (4). The gateway exchange GMSC 51 of the mobile communication network 11 in which the subscriber is located sends the incoming call of the mobile subscriber to the relevant location register GLR 31. Request information for routing (5) o The gateway location register GLR31 returns the location information of the subscriber to the gateway exchange GMSC 51 (6). The gateway switching center GMSC 51 performs a general call based on the received location information to reach the mobile subscriber 60.

However, in the conventional method described with reference to FIGS. 1 to 6, the location network of the visited network (that is, the mobile communication network at the roaming destination) is used. A communication network (Fig. 1 and Fig. 3) that uses a method in which a location register temporarily assigns a roaming number when an incoming connection is established, and a gateway location of a visited network A mobile subscriber roams between a mobile communication network (Fig. 4 and Fig. 6), which uses a method in which a register assigns a roaming number when registering a location. In this case, there is no way to assign a mouthing number to the mobile subscriber because the method of assigning a roaming number is different between the two mobile communication networks. As a result, there was a drawback that mobile participants could not roam.

On the other hand, the conventional roaming method is a personal mobile communication system in which the subscriber number assigned to the subscriber and the mobile station number assigned to the mobile station can be arbitrarily assigned. There is personal roaming that can be realized only between mobile communication networks.

Referring to FIG. 7, personal roaming control for performing personal roaming in such a personal mobile communication network. The method will be described.

In FIG. 7, the mobile communication network 411 that supports the personal mobile communication system is identified by the subscriber number PID4. Subscriber information P — user home location register holding data 4 HLR — P (Home Location Register for Personal mobility). 4 1 2 and mobile device number TID 4 The mobile device home location register that holds the mobile device information T-data 4 of the mobile device identified by the HLR — T (Home Location Register for Terminal mobility) 4 13 The mobile communication network 111 that supports the personal mobile communication system has subscriber information R-P of the roaming user identified by the subscriber number PID4. — User gateway that holds data 1 Location register GLR-P (Gateway Location Register for Personal mobility) 1 1 2 and mobile device identified by mobile device number TID 1 Mobile device home location register HLR — T (Horn e L ocation Register for Terminal mobility)

In FIG. 7, when a user of the mobile communication network 411 moves to the mobile communication network 111 (S31), the user roams to the mobile communication network 111. In this case, it is necessary to notify subscriber number PID 4 and mobile device number TID 1 of mobile device 115 to mobile communication network 111, which is the destination network, and register it (S 3 2). In this case, as a means for the user to notify the subscriber number PID 4 to the mobile communication network 111 via the mobile device 115, the user uses the subscriber number PID. Possess the user device that memorized 4 and load the user device. By attaching to the mobile terminal 1 15 of the mobile communication network 111 which is the destination network, the subscriber number PID 4 is automatically notified to the mobile communication network 111. A method is conceivable. As another means, it is also possible for the user to explicitly notify the roaming destination mobile communication network 111 via a dial or the like. .

By such means, the user can transfer the subscriber number PID 4 and the mobile station number TID 1 via the mobile station 115 to the mobile communication network 111 1 as a roaming destination network. , The combination of the subscriber number PID 4 and the mobile device number TID 1 is registered in the user gateway location register 112 of the mobile communication network 111 (S 3 3). Then, the user gateway location register 111 uses the subscriber number PID 4 as a key, and the user home of the mobile communication network 411 as the user's home network. The subscriber information is queried to the location register 412 (S334). In response to this inquiry, the user home accession register 4 12 outputs the subscriber information P — data 4, and the mobile communication network 11 1 outputs the subscriber information P — data 4 4 is registered as the roaming subscriber information R — P — datal in the user gateway location register 1 1 2 corresponding to the subscriber number PID 4 (S 3 5 ) o

By the above processing, the subscriber information of the user of the mobile communication network 411 is transferred to the mobile communication network 1 1 1, so that the user can make a call on the mobile communication network 1 1 1 Then, personal roaming is completed. In this way, personal roaming control can be performed between mobile communication networks that support the personal mobile communication system, but it is possible for the user to perform personal roaming control. If the home network does not have the personal mobile communication function, the location register GLR — P of the gateway of the roaming destination network is the user's home network. Even if the home location register HLR of the home network is directly contacted, the home location register integrates the subscriber information and the mobile device information. The problem is that it is not possible to retrieve and respond to subscriber information only, and to perform personal roaming. . DISCLOSURE OF THE INVENTION Accordingly, the purpose of the present invention is to provide a mobile subscriber roaming between communication networks employing different roaming number assignment schemes. Another object of the present invention is to provide a roaming mobile communication system and a method for enabling a roaming incoming connection between networks.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, mobile communication systems and methods according to the first and second embodiments of the present invention will be described.

FIG. 10 shows a configuration of a mobile communication system according to the first and second embodiments of the present invention.

In this mobile communication system, the first mobile communication network 210 temporarily stores the calling number at the time of the incoming connection when the current location register of the local network is connected. This is a mobile communication network that adopts the allocation method.The second mobile communication network 211 is a gateway to the visited network. The location register roams when the location is registered. A mobile communication network that uses a method of assigning numbers

In FIG. 10, ILR is an interworking schedule register which is a feature of the present invention, where VMSC is the local paternity office and VLR is the local area. Russia Ke one sheet Yo emissions re g data, HLR ho over-time opening to case Shi Yo emissions re g evening, GMSC the gateway exchange, GLR is ₀ 0 in the barrier Russia Ke one sheet Yo emissions re g evening Solid lines indicate communication lines, and broken lines indicate control lines.

As shown in FIG. 10, the inter-location register ILR 25 1 is a home location network of the first mobile communication network 210. While connected to the HLR 220 and the location register VLR 2 3 2 32, the home network of the second mobile communication network 2 1 1 Can register 2 2 1 and gateway register GLR 2 4 1 and It is connected .

FIG. 11 shows the location registration control method of the first embodiment and the incoming call control method in the mobile communication system shown in FIG.

As shown in FIG. 11, when the mobile subscriber 280 of the first mobile communication network 210 moves to the second mobile communication network 211 with a roaming contract, The mobile subscriber notifies the mobile communication network that the mobile subscriber has moved in the network in which the mobile subscriber is located (ie, the second mobile communication network 211). Execute the roaming position registration for In other words, when the mobile subscriber 280 moves to the mobile communication network 211 with a roaming contract (1), the serving switching center VMSC 273 of the mobile communication network is used. A location registration request (2) is made to the request. Upon receiving the security registration request (2), the serving switching center VMSC 273 sends the security registration request (3) to the gateway location register GLR241. Execute . Upon receipt of the location registration request (3), the gateway location register GLR 241 does not store the information of the subscriber who has requested location registration for the first time. Therefore, an area for storing the information of the subscriber is secured, and a roaming number is assigned to the subscriber (4).

In addition, the barrier location register GLR2 41 is connected to the interface location register ILR2 51 by this location. -Notify the mining number (5). The interworking location register ILR 251 stores this roaming number (6) and adds the subscriber's address. The home location register HLR 220 of the first mobile communication network 210, which constantly stores the subscriber information, receives its own (that is, i) Notify the identification number of the inter- work location register ILR2 51 (7). Then, the home location register HLR 220 is an identification number of the notified inter-work location register ILR 25 1. Is recorded as the identification number of the location register of the subscriber (8).

Next, an incoming call control is performed when an incoming call is generated to a mobile subscriber 280 of the first mobile communication network 210, which is roaming to the second mobile communication network 211. This will be described with reference to FIGS.

In this case, first, according to the subscriber number of the subscriber, the incoming call is the gateway switching center GMSC of the first mobile communication network 210 with which the subscriber subscribes as IAM. Routing is performed up to 26 1 (1). The gateway exchange GMSC 261 routes the incoming call of the mobile subscriber to the home location register HLR 220 of the first mobile communication network 210. Request information to be performed (2). Upon receiving the routing information request (2) from the gateway exchange GMSC 261, the home location register HLR 220 receives the subscriber information. To find the identification number of the location register of the subscriber. In this example, the identification number of the visited location register is the identification number of the inter-work location register ILR251. In addition, the home location register HLR 220 is used for the location register (i.e., the interworking location register). For the location register ILR 2 5 1), the incoming call of the subscriber is routed to the exchange of the mobile communication network where the subscriber is located. Request the allocation of a roaming number (3). Upon receiving the request for assigning a roaming number, the interworking location register ILR2 51 has already issued a roaming request to the subscriber. Since the storage number is stored (4), the stored roaming number is returned to the home location register HLR220.

(5) o

The home location register HLR 220 notifies the gateway switching center GMSC 261 of the mouth number (6), and the gateway switching center GMSC 26 1 The incoming call is routed as an IAM according to the roaming number (7), so that the incoming call is transferred to the mobile communication in which the subscriber is located. It reaches the gateway exchange GMSC 262 of the network.

The gateway exchange GMSC 262 routes the incoming call of the mobile subscriber 280 to the gateway exchange register GLR 241 to the serving exchange. Request information to be performed (8). Upon receiving the routing information request (8) from the gateway switching center GMSC 262, the gateway location register GLR2 41 receives the subscriber information. And returns the location information of the subscriber to the gateway exchange GMSC 262 (9). The gateway exchange GMSC 262 receives the A paging is performed based on the information and the call is received by the mobile subscriber 280 (10).

In the first embodiment, the interworking location register ILR 25 1 is located in the area where the first mobile communication network 210 is located. The location register acts like a home location register from the viewpoint of the second mobile communication network 211, but is actually an interface.ー Work location register ILR 25 1.

Next, FIG. 13 shows the location registration control method of the second embodiment in the mobile communication system shown in FIG. 10, and FIG. 14 shows the location registration control method shown in FIG. The incoming call control method of the second embodiment in the communication system is shown.

As shown in Fig. 13, when the mobile subscriber 2 82 of the second mobile communication network 211 moves to the first mobile communication network 210 with a roaming contract. The mobile subscriber 282 moves on the network in which it is located (i.e., the first mobile communication network 210) by moving the mobile subscriber itself. Performs roaming location registration to notify the communication network. In other words, when the mobile subscriber 282 moves to the mobile communication network 210 with a roaming contract (1), the mobile switching center VMSC 27 of the mobile communication network is used. A location registration request (2) is made for (1). Upon receiving the location registration request (2), the serving switching center VMSC 271 executes the location registration request (3) to the serving location register VLR231. .

Location register VLR2 3 1 When the request (3) is received, the information of the subscriber who has requested location registration for the first time is not stored, so an area for storing the information of the subscriber is secured, and the subscriber is requested to store the information. Useful location information. In addition, the location register VLR 231, which is located, is located relative to the location register ILR 251, which is located in the area. The identification number of the exchange and the identification number of the location register in the service area are notified (4).

The interworking location register ILR 251 stores the identification number of the serving switching center and the identification number of the serving location register. (5) Then, the fact that the subscriber number is roaming on the first mobile communication network 210 is stored, and the second mobile communication network 2 is stored. By notifying the home location register HLR 2 21 of 1 to its own identification number, the subscriber can similarly perform the first mobile communication. The network 210 is notified that it is roaming (6). The home location register HLR 2 21 of the second mobile communication network 21 1 stores the identification number of the inter-work location register. By remembering, it is remembered that the subscriber is roaming to the first mobile communication network 210 (7) o

Next, an incoming call control is performed when an incoming call is made to a subscriber 2882 of the second mobile communication network 211, which is roaming to the first mobile communication network 210. This will be described with reference to FIG.

In this case, first, according to the subscriber number of the subscriber, The incoming call is routed as an IAM to the gateway switching center GMSC 262 of the second mobile communication network 211 with which the subscriber subscribes (1). The gateway exchange GMSC 262 sends the incoming call of the mobile subscriber to the home location register HLR 221 of the second mobile communication network 211. Request information for routing (2).

The home location register HLR2221 requests routing information from the gateway exchange GMSC262.

When (2) is received, the information of the subscriber is searched and it is known that the subscriber is roaming to the first mobile communication network 210. Furthermore, the home location register HLR 22 1 is connected to the inter-work location register ILR 25 1 by the A request is made to assign a roaming number for routing the incoming call of the subscriber to the exchange of the mobile communication network where the subscriber is located (3).

The interworking location register ILR2 51 receiving the roaming number assignment request (3) is the first mobile communication network 210. A request for a roaming number is made to the current location register VLR231 (4). The location register, VLR 231, temporarily assigns a roaming number to the subscriber.

(5), this roaming number is notified to the interwork location register ILR2 51 (6).

The interworking location register ILR 25 1 stores the notified roaming number in the second mobile communication network 2 1 1. The home location register HLR 22 1 is notified (7), and the home location register HLR 22 1 The switching center GMSC 26 2 is notified of this roaming number (8). The gateway exchange GMSC 262 routes the incoming call as an IAM according to this oral number, and this is the subscriber's serving exchange VMSC 271. (9).

In this second embodiment, the interworking location register ILR 2 51 is located at the home as viewed from the first mobile communication network 210. The location register, when viewed from the second mobile communication network 211, operates like a gateway location register, but is actually an interworker.
