Description

technical field [0001] The invention relates to the communication field, in particular to a calling system and method. Background technique [0002] In the specifications that have been released or are being formulated by major standard organizations, how to realize the combination of ONLY service and user status in 3G networks such as Internet Protocol Multimedia Subsystem (IMS) is still a blank field. In the existing applications, only focus on the user's state presentation part or focus on the one number service, and neither of them are applied in the 3G network. [0003] In addition, existing technologies that are relatively close to the present invention exist in the following patent documents: Chinese patent application No. CN200610035074 "A User State Presentation Method and System" and patent No. CN200510063698 "A User State Presentation System and method" and the Chinese patent "a call processing and telephone terminal" with the patent number CN200510048296.

Problems solved by technology

[0004] Among them, CN200610035074 and CN200510063698 have the following disadvantages at the same time: they only define that the user's status presentation is a method for each terminal to observe each other's status, but are limited to the definition between the user's status release and presentation, and do not include the user's status combined with call

CN200510048296 defines a method of calling and state in PSTN network, this method needs to use specific telephone terminal, and the called number is fixed, can only modify the leaving state, has limitations, and because it does not take into account the function, so that the convenience and various functions brought by the IMS network have not been well applied

[0005] It can be seen that the calling terminal of the calling user in the current IMS cannot automatically and efficiently call the called terminal according to the user status of the called user, the call success rate is low, and user satisfaction is seriously reduced
