The IMS (IP Multimedia Subsystem), proposed by the 3GPP/3GPP2 (3rd Generation Partnership Project/3rd Generation Partnership Project 2) and based on SIP (Session Initiation Protocol), provides the feasibilities for multimedia of the next generation wireless network.
CAMEL protocal has introduced the third stage too, namely CAMEL Phase3. CAMEL3 begins to support GPRS conversation and PDP (Packet Data Protocol) context, increased the CAP interface of gprsSSF and gsmSCF, make the range of application of CAMEL business expand to the business of the data.

The cooperation framework is based on Teamwork theory and the rational BDI model, which presents the whole cooperative problem solving process from the team formation to the result evaluation. In the implementation of MBOS, an agent architecture named AGENTFRAME and its corresponding mechanisms including a multiple threads control mechanism and a conversation management method are proposed.
This paper analyzes various error resilience tools and their functions, and presents 2 error resilience strategies for 3G mobile streaming video services and mobile conversational services.
Rate-distortion optimized frame dropping and scheduling for multi-user conversational and streaming video
We propose a Rate-Distortion (RD) optimized strategy for frame-dropping and scheduling of multi-user conversational and streaming videos.
We consider a scenario where conversational and streaming videos share the forwarding resources at a network node.
For streaming video, a big buffer is used as the associated delay constraint of the application is moderate and a very small buffer is used for conversational video to ensure that the forwarding delay of every packet is limited.
