Embodiment 1

[0103] In this embodiment, it is assumed that the user terminal roams and has access to the home network, that is, the user has selected the P-CSCF of the home network for service processing, and the visited network and the home network of the user terminal are both IMS networks, and The IP CAN of the visited network is a GPRS network; the service request initiated by the user terminal is an emergency service request.

[0104] FIG. 4 is a flowchart of a method for a user to access a network in Embodiment 1 of the present invention. As shown in Figure 4, the method includes:

[0105] Step 401, the user terminal sends an emergency service request to the home network;

[0106] In this step, since the user terminal has selected the P-CSCF1 of the home network, when the user terminal initiates an emergency service request, the emergency service request will pass through the P-CSCF of the home network to the call session function of the home network; the emergency service request s...

Embodiment 2

[0136]In this embodiment, another method for users to access the network is provided. First, the user terminal initiates an attach request for attaching to the IP access network, and the IP access network returns a list of available access network elements through the attach request response, including One or more access network elements and their attributes, the attributes include: location information of network elements and / or capability information of network elements and / or service capabilities supporting different types of terminals, etc. Select an access network element that can meet the capabilities required by the user service, and the user terminal initiates an access request to it, such as sending a SIP registration message.

[0137] For example, users always need to initiate emergency services, and emergency services can only be provided through the P-CSCF of the visited location. Therefore, the user selects a P-CSCF of the visited location from the access network e...

Embodiment 3

[0163] Open Mobile Alliance (Open Mobile Alliance, OMA) Device Management / Client Provisioning (Device Management / Client Provisioning, DM / CP) can perform terminal device management and firmware update, and the interface with the user terminal can be a hypertext transfer protocol ( Hypertext Transfer Protocol, HTTP), Wireless Session Protocol (Wireless Session Protocol, WSP), Object Exchange Protocol (Object Exchange protocol, OBEX) or Synchronization Mark-up Language (SyncML), etc.

[0164]In this embodiment, another method for users to access the network is provided. First, the device management function based on the OMA DM / CP standard of the network is used to return a list of available access network elements for the user terminal, including one or more The access network element and its attributes, the attributes include: the location information of the network element and / or the capability information of the network element and / or the service capability supporting different...

Abstract

The invention disclose a method to access the network for user, in the invention, the terminal accesses the network which can require the user service according to requirement for property of net element, and it can realize the user service, and the service can be executed normally. The invention also provides a system for user terminal to access the network, and the system includes user terminal and service network.

Description

technical field [0001] The present invention relates to the service realization technology in the communication system, in particular to a method and system for realizing the user's access to the network in the next generation network for service realization. Background technique [0002] The IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) is a subsystem supporting IP multimedia services proposed by the 3rd Generation Partnership Project (3GPP) in Release 5. The core feature of the IMS is that the use of the Session Initiation Protocol (Session Initiation Protocol, SIP) has nothing to do with access. IMS is a multimedia control / call control platform in the packet domain, which supports session and non-session multimedia services, and provides a general service platform for future multimedia applications. For detailed definitions of IMS networks, please refer to relevant 3GPP standards. [0003] In the IMS network, various business forms can be provided. Emergency bu...
