Description

Method, device and system for realizing mobile communication service

technical field

The present invention relates to the technical field of communication, in particular to a method, device and system for realizing mobile communication services. the

Background technique

With the development and popularization of mobile communications, people's desire to choose a phone number has become increasingly strong, and operators have gradually taken this service as an important item in the quality of service. From a technical point of view, an HLR (Home Location Register, home location register) governs the IMSI (International Mobile Station Identity, International Mobile Subscriber Identity) and DN (Directory Number, phone number) of a specific number, that is, the user in the HLR Both IMSI and DN must be numbers within the jurisdiction of the HLR. When the user buys a mobile phone number or changes a SIM (Subscriber Identity Module, Subscriber Identity Module) card or UIM (UserIdentity Model, Subscriber Identity Module) card, the mobile phone number and the SIM card or UIM card must belong to the same HLR. The mobile subscriber identification code is not the same in different communication systems, for example, in GSM (Global System for Mobile communication, Global System for Mobile Communications), WCDMA (Wireless Code Division Multiple Access, wireless code division multiple access Access), TD_SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) or LTE (Long Term Evolution, long-term evolution) is called the International Mobile Subscriber Identity, expressed in IMSI; in CDMA communication, it is called the mobile user The identification code is represented by MIN; in the IMS (IP Multimedia subsystem, IP Multimedia Subsystem) system, it is represented by IMPI (IP Multimedia Private Identity, IP Multimedia Private Identity); although it is called and represented in different systems The methods are different, but they are all SIM card/USIM card/UIM card/ISIM card user identifiers in the network, which we collectively refer to as mobile subscriber identification codes here. the

In this way, there will be multiple HLRs in a city or a local network or a country without long-distance or roaming charges. When a user purchases a number or changes a card, the operator needs to find out the SIM card or UIM card that belongs to the same HLR as the phone number. , because the mobile subscriber identification code is stored in the SIM card or UIM card. This requires each business hall of the operator to reserve the SIM cards or UIM cards of each HLR, which causes a large waste of the operator's management costs and is also very difficult to manage. For example, when there are dozens of HLRs in a city, or hundreds or thousands of HLRs in a country, this kind of card management is very difficult and the cost is extremely high, so many operators can only reduce the service quality for customers at the cost of To reduce management costs and difficulties, that is, the SIM cards or UIM cards of each HLR can only be reserved in special business halls (such as the general business halls of provincial capital cities). the

Detailed ways

Analysis of the cause of this problem is related to the binding of the current authentication center and HLR. HLR and AC (Authentication Center, authentication center) are configured together. One AC belongs to one HLR, and the authentication center and HLR are bound to each other. The binding relationship between the IMSI and the HLR is caused, because in the existing system, the authentication center and the HLR are bound together for use. the

Now simply dividing the authentication center and HLR into two entities will also bring some new problems. For example, authentication requests need to be routed to AUC, location updates need to be routed to HLR, and the routing information used by the two messages is exactly the same. It is addressed by IMSI, and CN 200910163064.2 can be used to solve the addressing problem, but there are certain hidden dangers in reliability and waste of signaling resources in a large number of message forwarding. the

In the technical solution provided by the embodiment of the present invention, the AC is separated from the home location center (HLR or HSS), and the relationship between the AC and the home location center is one-to-many or many-to-many. At this time, for MSC/ VLR (Visited Mobile Switching Center/Visitor Location Register, mobile switching center/user location register), SGSN (Service GPRSSupporting Node, serving GPRS support node), CSCF (Call Session Control Function, call session control function), MME (Mobile Management Entity, Mobility ManagementEntity) or AAA server (Authentication, Authorization and Accounting, authentication, authorization and accounting), when it is necessary to address the HLR or HSS, the address information of the HLR or HSS can be obtained from the AC, and the ONE HLR or ONE HSS can be reached As a result, the coupling between the card and the home location center device is completely untied. the

It should be noted that the card in the embodiment of the present invention may specifically be a SIM card, a UIM card, a USIM card, or an ISIM card, and the like. the

In addition to storing the user's authentication data, the authentication center also needs to store the address information of the home location center corresponding to the currently used mobile subscriber identification code, such as the HLR GT address. the

Further, before the authentication center receives the authentication request message sent by the session control entity, the method also includes:

The session control entity uses the mobile subscriber identification code addressing mode to translate the destination address corresponding to the mobile subscriber identification code into the address of the authentication center (this translation action can be the session control entity or other entities on the network, Such as STP/ENUM/DNS/SLF, etc.), routing the authentication request message to the authentication center. the

In a specific application scenario, the session control entity addressing the home location center according to the received address information of the home location center includes:

When the session control entity sends a location update request or a registration request, it uses the address information of the home location center carried in the authentication response message to route the location update request to the home location center. the

As shown in Figure 1, a method for implementing a mobile communication service provided by the embodiment of the present invention, the authentication center stores the address information of the home location center corresponding to the mobile user identification code, and the method includes:

Step 101: the authentication center receives the authentication request message sent by the session control entity, and the authentication request message carries the mobile user identification code of the user terminal;

Step 102: The authentication center returns an authentication response message to the session control entity according to the mobile user identification code, and the authentication response message carries the address information of the home location center corresponding to the mobile user identification code of the user terminal , so that the session control entity addresses the home location center according to the received address information of the home location center. the

In the embodiment of the present invention, the AC carries the address of the home location center of the user terminal in the authentication response message, and the session control entity (in different systems, corresponding to different network entities, called different), use this address as the address of the home location center for addressing. the

In a specific application scenario, the session control entity uses the MSID to address the message sent to the AC, and uses the received home location center address to address the message sent to the home location center (since the message is already in the authentication response message The address of the home location center corresponding to the mobile subscriber identification code is obtained, so that the original IMSI/IMN/IMPI addressing mode can be changed, and the obtained address of the home location center can be used for addressing). Such a card belongs to which HLR or HSS can be specified, just need to tell the address of the HLR or HSS to the AC to which the card belongs, so as to realize the decoupling between the card and the home location center, which is convenient for the operator More flexible number allocation, card replacement, card replacement, and even remote card replacement greatly reduce the difficulty and cost of card management. At the same time, there is no hidden danger of reliability caused by signaling forwarding, and the waste of signaling circuitous resources. question. the

The authentication center and the mobile location center are separated from each other, and the relationship between the two is one-to-many or many-to-many. the

Under different network architectures, the session control entity includes Mobile Switching Center/Visitor Location Register MSC/VLR, Serving GPRS Support Node SGSN, Call Session Control Function CSCF, Mobility Management Entity MME or Authentication Authorization and Charging AAA. the

The home location center is HLR or HSS (Home Subscriber Server, Home Subscriber Server). the

Those skilled in the art can understand that the mobile subscriber identification code can be IMSI, MIN or IMPI. the

As shown in Figure 2, taking the location update process as an example, in another implementation method of mobile communication services provided by the embodiment of the present invention, the authentication center stores the address information of the home location center corresponding to the mobile subscriber identification code, and the Methods include:

Step 201: The visited MSC/VLR sends an authentication request message to the authentication center, and the authentication request message carries the mobile subscriber identity code IMSI of the user terminal;

In this step, the mode of addressing with the mobile subscriber identity code IMSI (the addressing with the mobile subscriber identity code can specifically be addressing with IMSI as GT) can be used to translate the destination address corresponding to the international mobile subscriber identity code IMSI into authentication The address of the center, so that the authentication request message can be routed to the authentication center after the authentication center is separated from the home location center. the

Step 202: the authentication center returns an authentication response message to the visited MSC/VLR, and the authentication response message carries the home location center address corresponding to the mobile subscriber identity code IMSI (in the embodiment of the present invention, the home location center can be HLR);

The visited MSC/VLR records the address information of the home location center corresponding to the mobile subscriber identification code carried in the authentication response message. the

It should be noted that the authentication center stores the corresponding relationship between the mobile subscriber identity IMSI and the home location center. the

It should also be noted that the purpose of steps 201 and 202 is to return the home location center address corresponding to the mobile subscriber identity code IMSI of the user terminal to the visited MSC/VLR by the authentication center. The embodiment of the present invention takes the location update process as an example for illustration , but it is not limited to the above location update process. Those skilled in the art can understand that the authentication request message is addressed to the authentication center by using the mobile user identification code, and other location updates, registration, unstructured, etc. need to go to the home location The center's request message is addressed to the home location center by using the home location center address information. That is to say, after the separation of the AC and the home location center, the mobile subscriber identification code can be used as the addressing basis of the AC, and is no longer suitable as the addressing basis of the home location center. In some session control entities, the mobile subscriber identification code is still used as the home location According to the addressing basis of the center, the AC can forward the non-authentication message to the home location center corresponding to the mobile user identification code according to the technology in CN 200910163064.2. The specific details will not be detailed here, see CN 200910163064.2 for details. the

Step 203: When the MSC/VLR initiates a location update request to the home location center, the MSC/VLR addresses the address of the home location center carried in the authentication response message as the destination address;

It should be noted that the embodiment of the present invention takes location update as an example for illustration, and the destination address of the location update request message is changed to the address of the home location center carried in the authentication response message. Those skilled in the art can understand that the present invention is also applicable to other communication processes (such as registration processes), that is, modifying the destination address of the home location center request message to the home location center address carried in the authentication response message. the

Step 204: After receiving the location update request message, the home location center may process it according to the existing flow, and return a location update response to the MSC/VLR. the

It should be noted that, in the embodiment of the present invention, the operation can be carried out according to the following principle: for the message routed by the user number MSISDN, the AC will not be involved, and can be processed in the manner of the prior art; the message routed to the AC Use the mobile subscriber identification code to address; after authentication, the route to the home location center uses the home location center address carried in the authentication response message for addressing. Specifically, session control devices such as MSC, VLR, and SGSN send location updates and other messages previously addressed to the home location center with the mobile subscriber identification code, the destination address is filled with the home location center address returned by the AC in the authentication response message. the

In the embodiment of the present invention, the authentication center is separated from the home location center. The authentication center stores the address information of the home location center corresponding to the mobile subscriber identification code, and the home location center corresponding to the mobile subscriber identification code is included in the authentication response message. The address information returned to MSC/VLR (under other network architectures, the session control entity here can also be SGSN, CSCF, MME or AAA), so that MSC/VLR can use the home location corresponding to the mobile subscriber identification code The address information of the center is used as the destination address to initiate operations such as location updates to the home location center, which realizes the decoupling between the card and the home location center, and facilitates more flexible number allocation, card replacement, card replacement, and even remote card replacement for operators. , which greatly reduces the difficulty and cost of card management, and at the same time, there is no hidden danger of reliability caused by signaling forwarding, and the problem of resource waste due to signaling detours. the

Fig. 3 is the implementation method of another kind of mobile communication service adopted by the embodiment of the present invention, applied to the SAE network architecture, the address information of the HSS corresponding to the mobile subscriber identification code is stored in the authentication center, and the method includes:

Step 301: MME sends an AIR authentication request message to the authentication center, and the authentication request message carries the mobile user identification code of the user terminal;

In this step, the destination address corresponding to the mobile subscriber identification code can be translated into the address of the authentication center, so that the authentication request message can be routed to the authentication center after the authentication center is separated from the home location center. the

Step 302: The authentication center returns an AIA authentication response message to the MME, and the authentication response message carries the address of the home location center corresponding to the mobile subscriber identification code (specifically, the home location center in the embodiment of the present invention can be HSS);

It should be noted that the authentication center stores the address information of the HSS using the mobile subscriber ID (it can be realized by storing the correspondence between the mobile subscriber ID and the HSS). the

It should also be noted that the purpose of steps 201 and 202 is to return the HSS address corresponding to the mobile subscriber identification code of the user terminal to the MME by the authentication center. The embodiment of the present invention uses the location update process as an example for illustration, but is not limited to the above-mentioned As for the location update process, those skilled in the art can understand that the authentication process in other scenarios such as location registration can achieve the above purpose. the

Step 303: When the MME initiates a location update request to the HSS, the MME uses the HSS address carried in the authentication response message as the destination address of the location update request message;

Step 304: After receiving the location update request message, the home location center may process it according to the existing flow, and return a location update response to the MME. the

The embodiment of the present invention is aimed at the SAE network architecture, the authentication center is separated from the HSS, the address information of the HSS corresponding to the mobile subscriber identification code is stored in the authentication center, and the authentication center stores the address information of the HSS corresponding to the mobile subscriber identification code in the authentication response message. The address information of the card is returned to the MME, so that the MME can use the address information of the home location center corresponding to the mobile subscriber identification code as the destination address to initiate operations such as location update to the HSS, which realizes the decoupling between the card and the HSS, and is convenient for operators. More flexible number allocation, card replacement, card replacement, and even remote card replacement greatly reduce the difficulty and cost of card management. At the same time, there is no hidden danger of reliability caused by signaling forwarding, and the waste of signaling circuitous resources. question. the

Further, when a user terminal accesses a network such as WIFI, WIMAX, EVDO, or fixed broadband, the AAA server in the network performs authentication and authorization operations. The embodiment of the present invention can also be applied to the above-mentioned scenario, and the implementation process is similar to that in FIG. 3 , except that the session control entity is the AAA server at this time. the

When the AAA server initiates an authentication request, it obtains the address information of the HSS from the authentication center. Specifically, the scenario where the 3GPP AAA server initiates an authentication request can be: when a new set of authentication information for a given user terminal needs to be delivered from the HSS, the authentication request is initiated by the 3GPP AAA server; a new trust Or when a non-trusted non-3GPP/IP access user accesses the 3GPP AAA server for authentication, or when one of the users registered with the 3GPP AAA server needs a new set of authentication information, the 3GPP AAA server will also initiate the authentication Request; when the 3GPP AAA server detects that the VPLMN or the access network has changed, the authentication request will be initiated by the 3GPP AAA server. the

When the AAA server sends a registration request to the HSS, it uses the HSS address carried in the authentication response message as the destination address of the registration request message, and routes the registration request to the HSS. Specifically, the following scenarios require the 3GPP AAA Server to actively initiate a registration request message:

1) For a given non-3GPP user, to register the current 3GPP AAA server address in the HSS. 3GPP AAA Server prepares to delete non-3GPP user access information (for example: STa, SWm, S6b session is terminated) or OCS (Online Charging System) initiates a disconnection, 3GPP AAA server notifies HSS of an upcoming disconnection process , at this time the HSS registers the non-3GPP user;

2) After a new user is authenticated by the 3GPP AAA server, the 3GPP AAA server initiates a registration request message. the

3) In order to download the user service list to the 3GPP AAA server when needed. Due to some reasons, the subscription data of a user is lost. At this time, the 3GPP AAA server needs to initiate a registration request message to the HSS. the

Fig. 4 is the implementation method of another kind of mobile communication service adopted by the embodiment of the present invention, applied to the IMS network architecture, the address information of the HSS corresponding to the mobile subscriber identification code is stored in the authentication center, including:

Step 401: The serving CSCF sends an AIR authentication request message to the authentication center, and the authentication request message carries the mobile user identification code of the user terminal;

In this step, the destination address corresponding to the mobile subscriber identification code can be translated into the address of the authentication center, so that the authentication request message can be routed to the authentication center after the authentication center is separated from the home location center. the

Step 402: The authentication center returns an AIA authentication response message to the serving CSCF, and the authentication response message carries the address of the home location center corresponding to the mobile subscriber identification code (specifically, the home location in the embodiment of the present invention The center can be HSS);

It should be noted that the authentication center stores the address information of the HSS using the mobile subscriber ID (it can be realized by storing the correspondence between the mobile subscriber ID and the HSS). the

It should also be noted that the purpose of steps 201 and 202 is to return the HSS address corresponding to the mobile subscriber identification code of the user terminal to the serving CSCF by the authentication center. The embodiment of the present invention uses the registration process as an example for illustration, but is not limited to the above For the registration process, those skilled in the art can understand that the authentication process in other scenarios can achieve the above purpose. the

Step 403: When the serving CSCF initiates a registration request to the HSS, the serving CSCF uses the HSS address carried in the authentication response message as the destination address of the registration request message;

Step 404: After receiving the registration request message, the HSS may process it according to the existing flow, and return a registration response to the serving CSCF. the

The embodiment of the present invention is aimed at the IMS network architecture, the authentication center is separated from the HSS, the address information of the HSS corresponding to the mobile subscriber identification code is stored in the authentication center, and the authentication center sends the HSS corresponding to the mobile subscriber identification code in the authentication response message The address information returned to the serving CSCF, so that the serving CSCF can use the address information of the home location center corresponding to the mobile subscriber identification code as the destination address to initiate operations such as registration requests to the HSS, realizing the decoupling between the card and the HSS, and facilitating Operators are more flexible in assigning numbers, changing cards, making up cards, and even making up cards in different places, which greatly reduces the difficulty and cost of card management, and at the same time, there are no hidden dangers of reliability and signaling circuitous resources caused by signaling forwarding. waste problem. the
