Multimedia service processing system, data sending method, data receiving method and terminal

Abstract

The invention discloses a multimedia service processing system, a data sending method, a data receiving method and a terminal. The multimedia service processing system comprises an application processor side and a processor side. The application processor side comprises a first multimedia data engine, a first IMS (IP Multimedia Subsystem) stack, a first network bridge, a first modem and a first router. The processor side comprises a second multimedia data engine, a second IMS stack, a second network bridge, a second modem and a second router. The application processor side and the processor side forward data through the first network bridge and the second network bridge. One of the application processor side and the processor side is a registration side according to a connection state when a session is established, and the other side is a non-registration side. The registration side finishes registration through adoption of the contained first IMS stack or the second IMS stack. Data and signals of the non-registration side are forwarded to the registration side through the first router and the second router. According to the technical scheme of the invention, the efficiency and flexibility of an IMS system are improved.

Description

technical field [0001] The invention relates to the field of Internet communication, in particular to a multimedia service processing system, a data sending and receiving method and a terminal. Background technique [0002] The IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) is proposed by the 3GPP standard organization on the basis of the R5 version, and is a general network architecture for providing multimedia services on an IP-based network. IMS has become the core network standard architecture in the all-IP era because it supports multiple access and rich multimedia services. With the maturity of technology, IMS has become the mainstream choice in the field of fixed voice, and has also been determined as the standard architecture of mobile voice by 3GPP and GSMA. [0003] In the prior art, VoIP (Voice over Internet Protocol, VoIP) digitizes an analog voice signal (Voice), and transmits it in real time on an IP data network (IP Network) in the form of a data pack...

AI Technical Summary

Problems solved by technology

[0004] However, the disadvantage of the single-side IMS stack mode in the prior art is that the load of the IMS stack will be relatively high, and the efficiency of the IMS system will be reduced; the single-stack mode usually uses a coprocessor (Coprocessor, CP). The routing of data and signaling will be more frequent, causing a certain load on the system and reducing the flexibility of the system
