Description

User registration processing method, device and system

Technical field

The present invention relates to the field of communications, and in particular to a user registration processing method, apparatus, and system.

Background technique

The IP Multimedia Core Subsystem (IMS) is an IP-based network architecture proposed by the 3rd Generation Partnership Project (3GPP) to build an open and flexible network. The business environment supports multimedia applications and provides users with rich multimedia services.

In the IMS service system, the control layer and the service layer are separated. The control layer does not provide specific services, and only provides necessary triggering, routing, and accounting functions to the service layer.

FIG. 1 is a schematic diagram of a basic IMS architecture defined by the 3GPP in the related art. As shown in FIG. 1 , the service triggering and control function in the control layer is implemented by a Call Session Control Function (CSCF). Call session control functions are divided into: proxy call session control function (Proxy-CSCF, referred to as P-CSCF), query call session control function (Interrogating-CSCF, referred to as I-CSCF) and service call session control function (Serving-CSCF, referred to as S-CSCF) three types.

The business layer is composed of a series of application servers (Application Servers, referred to as ASs), which can provide specific business services. The control layer (S-CSCF) controls the service trigger according to the subscription information of the user, and invokes the service on the AS to implement the service function.

The user's subscription data is stored in the home subscription server (HSS). When the user registers with the IMS, the subscription data is downloaded from the HSS to the S-CSCF to which the user is registered.

The end-to-end device in the session is called a user equipment (User Equipment, UE for short) and is responsible for the interaction with the user. Some UEs have multiple access networks, including packet switching through 3GPP (Packet Switch, referred to as For the PS) domain access network, access the network through other non-3GPP PS domains. Each user is assigned at least one SIP URI, called IMS public user identity (IMPU). The format is as follows sip:xyz@abc.com.

2 is a flowchart of IMS registration in the related art. As shown in FIG. 2, the process includes the following steps:

Step 201: The UE sends a SIP registration request message to the P-CSCF.

Step 202: After receiving the SIP registration request message, the P-CSCF sends the message to the I-CSCF of the home IMS network.

Step 203: After receiving the SIP registration request message, the I-CSCF initiates an inquiry to the HSS.

Step 204: If the user has not registered at the IMS, the HSS will return an S-CSCF list; if the user has already registered at the IMS, the HSS will return the S-CSCF currently registered by the user;

Step 205: If the I-CSCF receives the S-CSCF list, the I-CSCF selects an S-CSCF; the I-CSCF sends a registration request to the S-CSCF;

Step 206: The S-CSCF sends a Cx-put/Cx-pull message to the HSS.

Step 207: The HSS checks the status of the user. If the user does not register, sets the user status to registered, and records the registered S-CSCF name. The HSS returns the user's subscription data to the S-CSCF;

Step 208: The S-CSCF performs a service control operation according to the subscription information of the user.

Step 209: If the registration is successful, the S-CSCF returns a 200 OK message to the I-CSCF.

Step 210: The I-CSCF forwards the 200ok message to the P-CSCF.

Step 211: The P-CSCF forwards the 200ok message to the UE.

Step 212: The S-CSCF initiates a third-party registration message to the AS according to the subscription data.

Step 213: The AS returns a 200 ok message to the S-CSCF. Steps 212-213 are an example of step 208.

With the emergence of enterprise networks, there has been a wild registration technology. Enterprise network users, usually the user part of their IMPU has the same prefix, such as the IMPU of the mx company in the operator ddx account, the user part starts with mxcorp, such as sip:mxcorp.John@ddx.com, sip:mxcorp. Ms@ddx.com. When the enterprise network connects to the IMS network through IP-PBX, IP-PBX can register all users of the enterprise network to the IMS at one time with an IMPU containing a wildcard, such as sip:mxcorp@ddx.com. Each user of the subsequent enterprise network can call directly without having to register separately. FIG. 3 is a flowchart of a wildcard registration in the related art. As shown in FIG. 3, the process includes the following steps:

Step 301: The IP-PBX sends a SIP registration request message to the IBCF/P-CSCF by using the wildcard IMPU.

Step 302: After receiving the SIP registration request message, the P-CSCF sends the I-CSCF to the IMS network.

Step 303: After receiving the SIP registration request message, the I-CSCF initiates an inquiry to the HSS.

Step 304: If the user has not registered at the IMS, the HSS will return an S-CSCF list; if the user has already registered with the IMS, the HSS will return the S-CSCF currently registered by the user;

Step 305: If the I-CSCF receives the S-CSCF list, the I-CSCF selects an S-CSCF; the I-CSCF sends a registration request to the S-CSCF;

Step 306: The S-CSCF sends a Cx-put/Cx-pull message to the HSS.

Step 307: The HSS finds that this is a wildcard registration, and all relevant users are set to be registered, and the registered S-CSCF name is recorded. The HSS returns the subscription data of all users to the S-CSCF;

Step 308: The S-CSCF performs a service control operation according to the subscription information of the user.

Step 309: If the registration is successful, the S-CSCF returns a 200 OK message to the I-CSCF.

Step 310: The I-CSCF forwards the 200ok message to the IBCF/P-CSCF.

Step 311: The IBCF/P-CSCF forwards the 200ok message to the IP-PBX.

Step 312: The S-CSCF initiates a third-party registration message to the AS according to the subscription data.

Step 313: The AS returns a 200 ok message to the S-CSCF. It should be noted that steps 312-313 are an example of step 308.

Regardless of the method, in the related art, each user's data is required to be configured in the HSS. However, with the development of third-party (such as a business, a website, etc., especially the emergence of WebRTC technology, the above technology can not meet the demand.

1) If the operator can assign one or several number segments to a third party, such as 1895000xxxx assigned to a third party; or the third party IMPU has a common prefix, such as sip:mxcorp above. However, in the IMS network HSS, each user data cannot be configured. The maintenance of third-party user data is done by third parties themselves. This kind of demand is very common in reality. For example, operator A accesses IMS to a website xyz user, and its user's IMPU has a common prefix sip:xyz. However, for various reasons, how many users are there, the complete IMPU of each user, the HSS of the carrier network is not, or is incomplete.

2) Each user needs to access a fixed P-CSCF when registering, and the network will assign an S-CSCF. For the enterprise network, the IP-PBX accesses the IMS network through the IBCF/P-CSCF. The network often allocates an S-CSCF to serve a specific enterprise network user. After the registration is complete, the S-CSCF also knows which IBCF to pass. /P-CSCF is connected to the enterprise network. Then, for the above-mentioned third parties, such as websites, there are many users. The performance of assigning a fixed S-CSCF cannot meet the requirements; at the same time, it is used to be scattered everywhere, there is no unified portal like IP-PBX, and access to P-CSCF is different. The existing enterprise network registration method cannot meet the demand. In addition, for a specific user, in the above registration process, as shown in step 204 of FIG. 2, the registered S-CSCF cannot be recorded in the HSS.

Therefore, in the related art, the performance of assigning a unified S-CSCF to a registered user of a third-party user cannot meet the requirements, and the manner of unified registration cannot be realized due to the dispersion of the user.

Step S1601: The UE sends a SIP registration request message to the P-CSCF.

Step S1602: After receiving the SIP registration request message, the P-CSCF sends the message to the I-CSCF of the home IMS network.

Step S1603: The I-CSCF queries the TPUD for the registration status of the user. In this embodiment, the user has registered, and the TPUD sends the S-CSCF registered by the user to the I-CSCF. Optionally, the I-CSCF can be configured to identify which registrations are third-party users that require special handling. If it is a normal user, the I-CSCF no longer queries and directly executes the existing registration process;

Step S1604: The I-CSCF sends a registration request to the S-CSCF.

Step S1605: The S-CSCF updates the registration information to the HSS (same step S1507, step S1508);

Step S1606: The S-CSCF performs a service control operation according to the subscription information of the user.

Step S1607: The registration is successful, and the S-CSCF returns a 200 OK message to the I-CSCF.

Step S1608: The I-CSCF forwards the 200ok message to the P-CSCF.

Step S1609: The P-CSCF forwards the 200ok message to the UE.

Step S1610: The S-CSCF initiates a third party registration message to the AS according to the subscription data.

Step S1611: The AS sends a registration related information message to the TPUD, and the TPUD record saves the registration status of the user, and the corresponding S-CSCF;

Step S1612: The AS returns a 200ok message to the S-CSCF.

Steps S1610 to S1612 are optional. As an optimization, they may not be executed.

17 is a flow chart of logout of a user according to a preferred embodiment of the present invention. As shown in FIG. 17, the process includes the following steps:

Step S1701: The S-CSCF receives the logout request; there are many ways to log out, the user initiates, and the network initiates. This patent is concerned only with the processing after the S-CSCF receives the logout request. During the simplification, the process begins after the S-CSCF receives the logout request. The rest are related to the above related technologies;

Step S1702: The S-CSCF cancels the registration of the user to the HSS (same as the related technology);

Step S1704: The S-CSCF returns 200 ok;

Step S1705: The S-CSCF initiates a third party logout to the AS;

Step S1706: The AS initiates a logout to the TPUD, and the TPUD deletes the registration status of the user and the saved S-CSCF information.

Step S1707: The AS returns 200 ok to the S-CSCF.
