Problems solved by technology

However, the relevant information of the IMS domain obtained through registration may also change, for example, S-CSCF exits the service, Service-Route information changes, etc. Currently, when the registration information is abnormal (may be caused by the change of the IMS domain), it cannot be detected by the user. It is known that it will not actively initiate the re-registration process. At this time, the abnormality of the registration information may affect the normal operation of the business, resulting in a decrease in system performance.

Embodiment 1

[0044] In this embodiment, after the user registers, when the AGCF finds that the information obtained through registration is abnormal, it can take the initiative to re-register on behalf of the user, so as to regain valid registration information and continue to provide effective business services for the user. The user registration method of this embodiment is described in detail below, including:

[0045] Step 1. During the validity period of the registration, if the registration information is abnormal, the call cannot continue to use this information to provide subsequent services for the user, such as the S-CSCF network abnormality obtained through registration, Service-Route change, P-Associated-URI (in the IMS domain A header field of the SIP protocol stores the public user identity (PUI) information identifying an AGCF user in the IMS domain, and this information is used to determine the identity of the user in the IMS domain when the user registers and calls) change...

Embodiment 2

[0050] Image 6 It is a detailed flowchart of the user registration method in the AGCF system according to the second embodiment. The specific steps are as follows:

[0051] step 1: figure 2 After the described process is completed, the CS domain user gateway successfully registers with the AGCF and obtains valid registration information, such as Service-Route, calling S-CSCF, and P-Associated-URI. During the validity period of the registration, if the registration information has not changed, it will not be re-registered;

[0052] Step 2: One or more users (virtual users, one-to-one corresponding to the entity users under the user gateway) in the AGCF detect that the registration information is abnormal, such as calling the S-CSCF to exit the service, Service-Route change, etc.

[0053] Step 3: The AGCF initiates a user registration process to the I-CSCF for the abnormal user detected.

[0054] Step 4: The AGCF receives the registration response 3xx / 4xx / 5xx / 6xx messages ...

Abstract

The present invention provides a user registration method and device in an access control gateway functional system, the method comprising: the user registers successfully in the I-CSCF network element through the AGCF entity; the AGCF entity detects that the registration information of the user has occurred If it is abnormal, the user initiates re-registration with the I-CSCF network element. The present invention solves the problem of system performance degradation due to abnormal registration information in related technologies, and ensures that in the case of abnormal registration information, re-registration can be actively initiated to obtain effective business resources, satisfying the user's follow-up business functions, thereby effectively reducing the number of users due to registration information. Information abnormality affects the user's business use.

Description

technical field [0001] The present invention relates to the communication field, in particular to a user registration method and an AGCF entity in an Access Gateway Control Function (AGCF for short) system. Background technique [0002] AGCF is the European Telecommunications Standards Institute / European Telecommunications Standards Institute (ETSI) Telecom and Internet Converged Services and Advanced Network Protocol (Telecommunications and Internet converged Services and Protocols for Advanced Networking, referred to as TISPAN) NextGeneration Network (NextGenerationNetwork, The functional entities stipulated in the NGN framework are located in the Public Switched Telephone Network / Integrated Services Digital Network Emulation subsystem (referred to as PES). AGCF is the first connection point of Residential Gateway (RG for short) and Access Gateway (AG for short), as a control media gateway entity (MediaGateway Controller, MGC for short), providing PSTN for traditional anal...
