Embodiment Construction

[0034] For user equipment, terminal capability refers to an attribute of the terminal device, which is used to indicate the possibility of the device to generate or process a specific message content type, which can be negotiated during certain sessions. Examples of some basic capabilities are as follows: Does it support: audio, video, messaging, automatic devices, mobility, specific SIP methods (such as INVITE, CANCEL, etc.), presence status (PRESENCE), and supported languages ​​(such as English) , Chinese, etc.), the basic category of the device (such as desktop, portable or mobile phone, etc.). When a certain ability value changes from nothing to nothing, or from nothing to nothing, it is the terminal ability that has changed.

[0035] The present invention proposes a method to solve the problem of how to instantly notify related nodes in the network when a user has registered on the network but has not established a session when the ability changes. By immediately triggering t...

Abstract

The method includes following steps: when the terminal capacity changes, the subscriber equipment stops the current set login and refresh timer at client-side, and sends the login request message carrying new terminal capacity message to network; the network analyzes the login request message, and stores the new terminal capacity message; then the current login and refresh timer at network side set for the subscriber is stopped. The new login and refresh timer at network side starts for the subscriber; the response message carrying new login and refresh timer message is sent to subscriber equipment; according to the message about the new login and refresh timer in the response message, the login and refresh timer at network side is set again.

Description

Technical field [0001] The invention relates to a network using the SIP protocol, including an IP Multimedia Subsystem (IMS) network, and particularly refers to a method for notifying the network of the change of the terminal capability when the terminal capability changes in the IP Multimedia Subsystem (IMS). Background technique [0002] With the development of broadband networks, mobile communications will not only be limited to traditional voice communications. Multimedia services that combine multiple media types such as audio, video, pictures, and text will be gradually developed. Through cooperation with Presence and SMS The combination of data services such as WEB (web page) browsing, location information, PUSH (push service), file sharing, etc., can meet various needs of users, such as: [0003] Message service: instant message and chat room, multimedia short message; [0004] Video business: entertainment, multimedia information, daily communication; [0005] E-commerce...
