The network switching system 100 includes a network provided by a home-side carrier 1, a network provided by a switched-to carrier 2, and a user terminal (UE: User Equipment) 150 within the coverage area of these networks. Prepare. According to the present disclosure, in mobile phone, data communication services, etc., even when the service of the home-side telecommunications carrier 1 contracted by the user cannot be used due to alliances between telecommunications carriers, the user terminal 150 can If it is within the coverage area of another telecommunications carrier 2, the service provided by the home-side telecommunications carrier 1 can be continuously used. The user does not need to have a separate service contract with the other telecommunications carrier 2 to switch to.

The telecommunications carrier 1 is a home-side carrier with which the user of the user terminal 150 has a service contract. The telecommunications carrier 1 includes an integrated data management server 122 having a UDR (Unified/User Data Repository), a subscriber server 124 for managing subscriber information of the telecommunications carrier 1, and a communication control server 126. , and a base station 128 . The telecommunications carrier 2 is a switching carrier with which the user does not have a service contract. The carrier 2 includes at least a unified data management server 142 with a UDR (Unified/User Data Repository) and a subscriber server 144 . Although the telecommunications carrier 2 is affiliated with the telecommunications carrier 1, the integrated data management server 142 does not hold the subscriber information of the users contracting with the telecommunications carrier 1. FIG. Hereinafter, when there is no need to distinguish between the integrated data management server 122 and the integrated data management server 142, they may simply be referred to as an integrated data management server. Moreover, when there is no need to distinguish between the subscriber server 124 and the subscriber server 144, they may simply be referred to as a subscriber server.

The configuration of FIG. 1 is exemplary, is not limited to this configuration, and can include other incidental elements. For example, in the illustration, there is one carrier (communication carrier 2) to which switching is to be made, but there may be more than one. The integrated data management servers 122, 142, the subscriber servers 124, 144, the communication control server 126, and the base station 128 are respectively one, but they are logically or physically one device, or It may be implemented using multiple devices. That is, the functions may be concentrated in one device, or the functions may be distributed among a plurality of individual devices. For example, although there is one communication control server 126 and one base station 128, a plurality of communication control servers 126 and base stations 128 may be arranged. Further, although integrated data management server 122 (142) and subscriber server 124 (144) are shown as separate devices, subscriber server 124 (144) is integrated data management server 122 (142). It may be configured to accommodate functionality.

The user terminal 150 uses the communication service (mobile phone, data communication service, etc.) provided by the carrier 1 through the first route 162 configured by the network 120 of the carrier 1 under normal conditions. In an "abnormal state" where a failure or the like occurs in a part of the network 120 of the telecommunications carrier 1 (integrated data management server 122), the user terminal 150 is connected to the part of the network 120 of the telecommunications carrier 1 in which an abnormality has occurred. to the network 140 of carrier 2. After switching, the user terminal 150 connects to the communication service provided by the telecommunications carrier 1 through the second route 164 configured by the network 120 of the telecommunications carrier 1 and the network 140 of the telecommunications carrier 2, in which no abnormality has occurred. and continue to use the “equivalent communication service”. The user of the user terminal 150 can use the network 120 of the communication carrier 1 and the network 140 of the communication carrier 2 to provide the same communication service as the communication service provided by the communication carrier 1 without being aware of the occurrence of an abnormality. Available through a combined network.

Here, "normal" means a state in which the network 120 of the communication carrier 1 is normal.

In addition, "at the time of abnormality" is a state in which there is an abnormality in the network 120 of the telecommunications carrier 1, and temporary It means a state in which the integrated data management server 122 on the home side cannot be accessed.

"Equivalent communication service" is a service that can be provided in common by the communication carrier 1 and the communication carrier 2, and includes at least a part of the communication service provided by the communication carrier 1. The "equivalent communication service" includes, for example, at least part of emergency call origination, general call origination, SMS service, data communication service, and the like. "Comparable communication service" does not include additional network services provided independently by Carrier 1 or Carrier 2.

Various programs can be stored in various memories such as ROM and RAM, and recording media such as HDD (storage).

The SIM 152 installed in the user terminal 150 stores the contract profile of the user contracting with the telecommunications carrier 1 . The subscription profile of the SIM 152 stores the user's subscriber information, including the subscriber identification number (IMSI: International Mobile Subscriber Identity) assigned to the mobile phone line contract, the subscriber user's telephone number (MSISDN: Mobile Subscriber Identity). International Subscriber Directory Number) and SIM card number (ICCID: Integrated Circuit Card Identifier).

The user of the user terminal 150 only needs to have a contract with the telecommunications carrier 1 and does not need to have a contract with the telecommunications carrier 2 . When an abnormality is detected in the network 120 of the carrier 1, based on the contract profile stored in the SIM 152 of the user terminal 150, the user's temporary contract profile information 400 is transferred to the integrated data management system of the carrier 2. Created on server 142 . In addition, location management information 500 including the address of the communication control server 126 to which the subscriber server 144 is connected is created in the integrated data management server 142 of the telecommunications carrier 2 . The user terminal 150 can use the communication service of the communication carrier 2 when the temporary contract profile information 400 and the location management information 500 are created.

(Integrated data management servers 122, 142)
The integrated data management server 122 can be implemented by an information processing device with a known configuration. The integrated data management server 122 is a computer or a server computer located on the cloud. The integrated data management server 122 is a computer having hardware resources such as a CPU (processor), ROM (Read Only Memory), RAM (Random Access Memory), and HDD (Hard Disk Drive). The CPU executes various programs stored in the storage unit. Thus, information processing by software is realized using hardware resources. Various programs can be stored in various memories such as ROM and RAM, and recording media such as HDD (storage).

The unified data management server 122 has a UDR (Unified/User Data Repository). The integrated data management server 122 stores a collection of information on subscribers contracting with the telecommunications carrier 1 organized so that it can be retrieved or stored in the UDR.

The integrated data management server 142, like the integrated data management server 122, stores a collection of information of subscribers who subscribe to the telecommunications carrier 2 arranged so that they can be retrieved or stored in UDR. The integrated data management server 142 further temporarily stores the temporary contract profile information 400 for the subscriber of the telecommunications carrier 1 and the location management information including the address of the communication control server 126 to which the subscriber server 144 is connected. 500 can be stored. Integrated data management server 142 manages communication service types provided to UE 150 based on temporary contract profile information 400 . The integrated data management server 142 manages the address of the communication control server 126 of the carrier 1 in which the UE 150 is located, based on the location management information 500 . The subscriber information, temporary contract profile information 400, and location management information 500 are stored in a memory or storage that is a storage unit. Details of the temporary contract profile information 400 and the location management information 500 will be described later with reference to FIGS. 4 and 5, respectively.

(Subscriber servers 124, 144)
The subscriber server 124 manages contract information and authentication information of users subscribing to the system provided by the telecommunications carrier 1, and notifies the communication control server 126 of these information upon location registration.

(Communication control server 126)
The communication control server 126 manages location registration of the user terminal 150, calling, handover between base stations, and the like. Further, the communication control server 126 decides to change the subscriber server 124 to be connected to the subscriber server 144 in response to the detection of the abnormality. The communication control server 126 stores in advance route information 300 that defines the address of the subscriber server 144 to be connected in the event of an abnormality. Switch from subscriber server 124 to subscriber server 144 . Details of the route information 300 will be described later with reference to FIG.

It is assumed that the communication carrier 1 and the communication carrier 2 comply with the same communication standard (for example, the 4th Generation (4G) communication standard or the 5th Generation (5G) communication standard). When the system 100 complies with the 4G communication standard, the subscriber servers 124 and 144 are HSS (Home Subscriber Server) and the communication control server 126 is MME (Mobility Management Entity) 118 . When the system 100 conforms to the 5G communication standard, the subscriber servers 124, 144 are UDM (Unified Data Management) and the communication control server 126 is AMF (Access and Mobility Management Function).

FIG. 2 is a sequence diagram of a system 100 for switching networks according to one embodiment of the present disclosure. In this embodiment, when an abnormality occurs in a part of the network 120 of the telecommunications carrier 1 (integrated data management server 122), the abnormality is detected and the part of the network 120 of the telecommunications carrier 1 in which the abnormality occurs part is switched to carrier 2's network 140 .

Prior to the processing, it is assumed that the user terminal 150 uses only the network 120 provided by the telecommunications carrier 1, that is, uses various communication services via the first route 162. FIG. In addition, it is assumed that the communication control server 126 registers in advance the route information 300 for specifying the connection destination when the communication control server 126 is abnormal and when it is normal.

FIG. 3 exemplifies the data structure of route information 300 registered in the storage unit of the communication control server 126. As shown in FIG. As shown in FIG. 3, the "route information" includes the subscriber identification number, the address of the subscriber server 124 of the telecommunications carrier 1 which is the connection destination during normal operation, and the communication carrier's address which is the connection destination during abnormal conditions. It contains an item with the address of the subscriber server 144 . Both a normal connection destination and an abnormal connection destination are assigned to one subscriber identification number. There may be a plurality of addresses of the subscriber server 144, which is the connection destination in the event of an abnormality. If there is more than one, the "route information" may further include an item of priority. A plurality of addresses of the subscriber server 144, which are connection destinations in the event of an abnormality, can be prioritized, and connection destinations can be assigned in descending order of priority. In the event of a disaster, anomalies may occur in multiple telecommunications carriers. By assigning a plurality of addresses to connection destinations in the event of an abnormality, when an abnormality occurs in the communication carrier with the highest priority, it is possible to allocate the communication carrier with the next priority.

Processing begins in step S202. In step S<b>202 , the subscriber server 124 performs a health check to monitor the state of the integrated data management server 122 . A health check of the integrated data management server 122 is performed periodically.

In step S204, when an abnormality occurs in the integrated data management server 122, in step S206, the subscriber server 124 acquires a health check result indicating an abnormality from the integrated data management server 122, or obtains a health check response from the integrated data management server 122 in step S206. get no response. In step S208, when the subscriber server 124 acquires a health check result indicating an abnormality or detects that there is no response to the health check result, the subscriber server 124 determines that the integrated data management server 122 has an abnormality. Next, in step S210, the subscriber server 124 transmits to the communication control server 126 an abnormality occurrence notification indicating that an abnormality has occurred.

In step S<b>212 , the communication control server 126 turns on an abnormality occurrence flag indicating that an abnormality has occurred and stores it in the storage unit of the communication control server 126 .

In step S<b>214 , the communication control server 126 receives the location registration request signal from the user terminal 150 via the base station 128 . The location registration request signal includes the subscriber identification number read from SIM 152 of user terminal 150 . In this example, the subscriber identification number of the user terminal 150 is assumed to be "aa" for convenience of explanation. Note that in this disclosure, when the same signal is transmitted through more than one node, it may be represented as one step. For example, in step S214, the transmission of the location registration request signal from the user terminal 150 to the base station 128 and the transmission of the location registration request signal from the base station 128 to the communication control server 126 are represented by one step. Note that the processing shown in FIG. 2 is merely exemplary, and the order thereof may be changed, and processing may be added. For example, step S214 may not be after step S212, but may be before step S218 (eg, before step 202).

In step S216, the communication control server 126 determines that there is a failure in the first route 162 and that the first route 162 needs to be switched to another route if the abnormality flag is ON. The communication control server 126 uses the subscriber identification number as a key to identify the connection destination of the communication carrier 2 of the communication control server 126 . The communication control server 126 reads, from the route information 300 (FIG. 3), the address of the subscriber server 144, which corresponds to the subscriber identification number of the user terminal 150 and is the connection destination in the event of an abnormality. In the example of FIG. 3, the subscriber server address of the connection destination at the time of abnormality corresponding to the subscriber identification number "aa" is the address "BBB" of the subscriber server of the second business operator and the address of the subscriber server of the third business operator. It is "CCC" of the server. In the example of FIG. 3, "1" has the highest priority, and as the value increases from 2 to 3, the priority decreases in order. The communication control server 126 identifies the address "BBB" of the subscriber server 124 of the carrier 2, which has the highest priority.

Returning to FIG. 2, in step S218, the communication control server 126 inquires of the user terminal 150 about the telephone number based on the subscriber identification number included in the location registration request signal.

In step S220, the user terminal 150 reads from the SIM 152 the contract profile corresponding to the subscriber identification number "aa".

By the way, the integrated data management server 122 of the telecommunications carrier 1 stores a contract profile that associates the subscriber identification number of the user terminal 150 with the telephone number and the like. However, if an abnormality occurs in the integrated data management server 122 of the telecommunications carrier 1, the integrated data management server 122 cannot access the contract profile for the subscriber identification number. Under such circumstances, in order to provide the user terminal 150 with a communication service equivalent to the communication service of the telecommunications carrier 1 via the second route 164, the telecommunications carrier 2 must set You need to create a contract profile. A temporary contract profile is created in accordance with the processing from step S222 to step S228 below.

In step S222, the user terminal 150 sends the telephone number associated with the user terminal 150 included in the subscription profile to the communication control server 126 along with the subscriber identification number.

Next, in step S224, the communication control server 126 adds the telephone number obtained in step S222 and an emergency parameter indicating that an abnormality has occurred to the location registration request signal obtained from the user terminal 150, and updates the location registration request signal. create a location registration request signal.

In step S226, the communication control server 126 updates the integrated data management server 142 of the telecommunications carrier 2 via the subscriber server 144 of the telecommunications carrier 2 at the address ("BBB") specified in step S216. location registration request signal.

Next, in step S228, the integrated data management server 142 of the communication carrier 2 determines whether the updated location registration request signal includes an emergency parameter, and if the emergency parameter is included, the updated location registration request Based on the signal, temporary contract profile information 400 and in-range management information 500 are created and stored in the storage unit.

Temporary contract profile information 400 includes information necessary for continuing to provide communication services equivalent to those provided by carrier 1 .

FIG. 4 illustrates the data structure of temporary contract profile information 400 registered in the storage unit of integrated data management server 142 . Temporary contract profile information 400 is created to allow user terminal 150 to temporarily use network services provided by carrier 2 . As shown in FIG. 4, the "temporary contract profile information" includes a subscriber identification number, a telephone number, and a service type that the carrier 1 provides to the user terminal 150 and that the carrier 2 can also provide. including the items of Here, the service type includes at least some items such as emergency call origination, general call origination, SMS service, and data communication service.

The location management information 500 includes the address of the communication control server 126 where the UE 150 corresponding to the subscriber identification number of the communication carrier 1 is located. The integrated data management server 142 of the communication carrier 2 uses the location management information 500 to manage the location information of the user terminal 150 managed by the communication carrier 1 corresponding to the subscriber identification number "aa".

FIG. 5 exemplifies the data structure of the location management information 500 registered in the storage unit of the integrated data management server 142. As shown in FIG. As shown in FIG. 5, the "location management information" includes items of a subscriber identification number and the address of the communication control server where the UE 150 is located.

Returning to FIG. 2, in step S230, the integrated data management server 142 of the telecommunications carrier 2 notifies the subscriber server 144, the communication control server 126, and the base station of the completion of location registration of the user terminal 150. 128 to the user terminal 150 .

In step S232, upon obtaining the location registration completion notification, the user terminal 150 can use the communication service specified by the temporary contract profile information 400 via the second route 164. FIG.

According to the present disclosure, even if a failure or the like occurs in part of the network 120 of the telecommunications carrier 1 (integrated data management server 122), the user terminal 150 can provide a communication service equivalent to the communication service provided by the telecommunications carrier 1. can be used using the network system provided by the telecommunications carrier 2. A user of the user terminal 150 can use the network system provided by the telecommunications carrier 2 without being aware of the occurrence of an abnormality and without making a service contract with the telecommunications carrier 2 .

FIG. 6 is a sequence diagram of a system 100 for switching networks according to an embodiment of the present disclosure. In the present embodiment, when a part of the network 120 of the telecommunications carrier 1 (the integrated data management server 122) returns to normal, the Return the connection destination to the network 120 .

Processing begins in step S602. In step S<b>602 , the subscriber server 124 regularly performs health checks to monitor the state of the integrated data management server 122 . In step S606, when a health check result indicating normality is obtained, or when a response to the health check is returned from the integrated data management server 122, in step S608, the subscriber server 124 changes the integrated data management server 122 from an abnormal state to a normal state. Determine that the state has returned. Next, in step S610, the subscriber server 124 sends a notification to the communication control server 126 that it has returned to normal.

In step S<b>612 , the communication control server 126 turns off the abnormality occurrence flag indicating that the communication control server 126 has returned to normal, and stores the flag in the storage unit of the communication control server 126 . Turning off the abnormality flag indicates that the first route 162 is normal. Therefore, the communication route of the user terminal 150 is returned from the temporary second route 164 in the abnormal state to the first route 162 in the normal state.

In step S 614 , the communication control server 126 receives the location registration request signal from the user terminal 150 via the base station 128 . The location registration request signal includes the subscriber identification number read from the SIM of user terminal 150 .

In step S616, if the abnormality occurrence flag is off, the communication control server 126 returns the first route 162 to normal, and returns the route from the abnormal second route 164 to the normal first route 162. The communication control server 126 identifies the connection destination of the communication carrier 1 of the communication control server 126 based on the subscriber identification number acquired in step S614. The communication control server 126 reads, from the route information 300 (FIG. 3), the address "AAA" of the subscriber server, which is the connection destination during normal operation, corresponding to the subscriber identification number of the user terminal 150.
