Method and system for realizing personalized service in packet service

Abstract

The invention relates to the mobile communication field, discloses a method and system for implementing individualized services in group service, making it still able to implement individualized services of group service when terminals do not support the ability of carrying media in SIP messages. In the invention, service subscriber configures individualized data by individualized server and as requesting group service, sends request information to AS, and the AS obtains the configured individualized data from the individualized server according to the request information and adds these individualized data by preset policies into the request information, and then sends this request information to the called user. After this, AS returns request response information to the caller, where the request response information carries the corresponding individualized data obtained from the individualized server and added by the preset policies.

Description

[0001] Technology area [0002] The invention relates to the field of mobile communication, in particular to group services. Background technique [0003] The Internet Protocol Multimedia Core Network Subsystem (IP Multimedia Subsystem, referred to as "IMS") is a third-generation partnership project (3 rd Generation Partnership Project, referred to as "3GPP") defines an Internet Protocol (Internet Protocol, referred to as "IP") multimedia subsystem in the Wideband Code Division Multiple Access (WCDMA) network, is The third generation mobile communication (The Third Generation, referred to as "3G") mobile network implements packet voice (Voice over IP, referred to as "VoIP") and packet data, and provides a unified target network for multimedia services and applications. [0004] IMS uses the IP packet domain as the bearer channel for its control signaling and media transmission, and uses the Session Initiation Protocol (SIP) as the protocol for call control signaling to reali...

Problems solved by technology

[0015] In practical applications, the above solution has the following problems: the operation is complicated, and it takes up more air interface resources. When the sending terminal does not support the ability to carry media in SIP messages, it is impossible to realize the personalized service of the group business.

[0016] The main reason for this situation is that the user needs to specify the specific media contained in the request when initiating a business request for personalized services, and for infrequently changing personalized data, such as ringtones and group logos, such operations quite complicated

[0017] Since the sender sends the content of the media itself or the link of the media to the AS through the air interface, more air interface resources are occupied. For personalized data that does not change frequently, the air interface resources are repeatedly occupied, resulting in a waste of air interface resources.

[0018] Since the sender terminal does not support the ability to carry media in SIP messages, personalized data cannot be carried in the sent request message, and personalized services for group services cannot be realized
