Problems solved by technology

[0022] The present invention provides a method for IMS user registration, which is used to solve the problem that the prior art only provides a method of initiating registration with the SIPURI logo as the basic logo, the user has no choice, and the implementation is relatively complicated in order to meet the requirements of traditional user terminals and user habits.
[0023] The present invention also provides a method for IMS session connection, which is used to solve the problems of number conversion and intercommunication that may exist in the prior art, and the need for ENUM resolution and DNS resolution in the connection process, which makes the connection more complicated.

example 1

[0075] Example 1: The database in the Home Subscriber Server (HSS) is not modified, and the E.164 identifier is converted into an identifier in the SIP URI format to complete authentication and registration. The specific processing steps of this example are as follows:

[0076] S101. A user initiates a registration request using an E.164 identifier as a basic identifier.

[0077] Since the existing protocol stipulates that the SIP URI is the basic identifier of the IMS, and the E.164 identifier is the subordinate identifier, in order to implement the present invention, the E.164 identifier is defined as the basic identifier.

[0078] In this way, the user can use the E.164 identifier as the basic identifier to initiate a registration request to the network side. S102. The IMS terminal converts the E.164 identifier into an identifier in SIP URI format, and adds the identifier in SIPURI format to the registration request message.

[0079] The IMS terminal uses the conversion m...

example 2

[0092] Example 2: modify the database in the HSS, and convert the E.164 identifier into an identifier in SIP URI format to complete authentication and registration. The specific processing steps of this example are as follows:

[0093] S201. The user initiates a registration request using the E.164 identifier as a basic identifier.

[0094] Since the existing protocol stipulates that the SIP URI is the basic identifier of the IMS, and the E.164 identifier is the subordinate identifier, in order to implement the present invention, the E.164 identifier is also defined as the basic identifier.

[0095] In this way, the user can use the E.164 identifier as the basic identifier to initiate a registration request to the network side.

[0096] S202. The IMS terminal converts the E.164 identifier into an identifier in SIP URI format, and adds the identifier in SIPURI format to the registration request message.

[0097] The IMS terminal uses the conversion module to add a domain name...

example 3

[0110] Example 3: Convert the E.164 identifier into an identifier in TEL URI format to complete authentication and registration. The specific processing steps of this example are as follows:

[0111] S301. The user initiates a registration request using the E.164 identifier as a basic identifier.

[0112] Since the existing protocol stipulates that the SIP URI is the basic identifier of the IMS, and the E.164 identifier is the subordinate identifier, in order to implement the present invention, the E.164 identifier is also defined as the basic identifier.

[0113] In this way, the user can use the E.164 identifier as the basic identifier to initiate a registration request to the network side.

[0114] S302. The IMS terminal converts the E.164 identifier into an identifier in TEL URI format, and adds the identifier in SIP URI format to the registration request message. (Refer to the protocol for the conversion method: RFC2806)

[0115] S303. The P-CSCF acquires the address o...

Abstract

The invention relates to a method for registering user in IP multimedia subsystem, for solving the present technique which can only register with the SIP URI mark as base mark. The inventive method comprises: user uses E.164 mark as basic mark to initialize register request; IMS terminal transforms said E.164 mark into the register mark meeting SIP protocol, and adds the register mark into the register request message; the network device of IMS network, based on said register request message, completes the priority identification and register.

Description

technical field [0001] The invention relates to a 3G wireless network, in particular to an IP multimedia terminal and a method for user registration and session connection in the system. Background technique [0002] The IP Multimedia Subsystem (IMS) is a subsystem superimposed on the packet network by the 3rd Generation Partnership Project (3GPP). The IMS uses the packet domain as the bearer channel for its control signaling and media transmission, and introduces the Session Initiation Protocol (SIP) as a service control protocol. Provide rich multimedia services by separating service control from bearer control. [0003] In IMS applications, in order to complete the registration function of the user (UE) and the calling and called services, 3GPP defines two public identities: [0004] 1. Public User Identity (IMPU): Users use the IMPU to communicate. Each IMS user has one or more IMPUs. The IMPU has a Session Initiation Protocol Universal Resource Identifier (SIP URI) ...
