Problems solved by technology

The two operations have a large similarity, resulting in repeated communication overhead and lack of efficiency
There are many network elements involved in message processing and message forwarding in the whole process, which will cause the whole registration process to take too long and reduce user perception

Embodiment Construction

[0051] Embodiments of the present invention provide an IMS registration method and device, which are used to simplify the IMS registration process, reduce the processing load of network elements, and improve user perception.

[0052] The embodiment of the present invention proposes a scheme for optimizing the IMS registration process by analyzing the functions of each network element and message interaction sequence in the IMS registration process. Through this, the two stages of the original IMS registration process are analyzed. In the home network, the authentication control function is forwarded from the S-CSCF to the P-CSCF to complete, and when the UE enters the IMS network, the user's legality is authenticated. If it is illegal, the user will be eliminated directly. If the P-CSCF successfully authenticates the user, it will add the "Authentication Success Flag (Authentication Success Flag)" extension header in the registration request REGISTER, that is, carry the indic...

Abstract

The invention discloses an IMS (Information Management System) registration method and device, which is used for simplifying IMS registration flows, and reducing the processing load of the network elements, so as to promot the user perception. The IMS registration method comprises the following steps: when a P-CSCF (Proxy-Call Session Control Function) receives a registration request message sent by UE (User Equipment), the P-CSCF judges whether the UE belongs to a home network or not; when the UE belongs to the home network, the P-CSCF carries out legitimacy authentication to the UE; and when the authentication to the UE is successful, the P-CSCF sends the new registration request message of the UE to an S-CSCF (Serving-Call Session Control Function), wherein the registration request message carries indication information that the legitimacy authentication to the UE is successful.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to an IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) registration method and device. Background technique [0002] The existing IMS registration process usually consists of two stages. The first stage is how the network challenges the user, and the second stage is how the user equipment (User Equipment, UE) responds to the challenge and completes the registration. Each stage is initiated by the UE sending a registration request message, through the proxy call session control entity (Proxy-CSCF, P-CSCF), querying call session control entity (Interrogating-CSCF, I-CSCF), serving call session control entity (Serving -CSCF, S-CSCF), home subscription data server (Home Subscriber Server, HSS) and other network elements to exchange messages. [0003] In the entire registration process, due to the large number of network elements involved and the complex mess...
