Example Embodiment

[0040] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] At present, there are a variety of wireless broadcast and multicast network structures. In order to simplify network design and realize convenient communication, at the same time, heterogeneous wireless broadcast and multicast networks and even heterogeneous broadband cellular mobile networks can be organically combined. The invention innovatively proposes a multi-domain wireless broadcast multicast network system based on collaborative technology, which is composed of three parts: a basic coverage domain, a relay enhanced domain, and an extended service domain.

[0042] See figure 1 , Specifically introduce the structure and composition of the network. It takes the wireless broadcast multicast single frequency network as the core, expands the coverage of...

Abstract

A multi-domain radio broadcast multicast network system based on a cooperative communication technology and a method thereof. The system comprises a basic overlay domain, a relay enhancement domain and an expanded service domain. The basic overlay domain composed of a radio broadcast multicast single frequency network is taken as a core, the overlay range of the radio broadcast multicast single frequency network is expanded by the relay enhancement domain so as to realize seamless overlay of the radio broadcast multicast single frequency network and a homogeneous radio broadcast multicast network and accomplish a fusion of the radio broadcast multicast single frequency network and an heterogeneous radio broadcast multicast network. The system acquires a diversity-multiplexing gain of radio transmission by the cooperative communication technology, thus solving a bottle-neck problem of radio broadcast data service transmission among different domains. The method and the system can expand the overlay range of the radio broadcast multicast network, enhance system capacity and service quality, realize convenient networking, and satisfy high-quality and high-speed transmission demand of the next generation of the radio broadcast multicast.

Description

technical field [0001] The invention relates to a cooperative technology-based multi-domain wireless broadcast multicast network system and method aimed at broadcast multicast service transmission, and belongs to the technical field of wireless broadcast and multicast communication. Background technique [0002] Wireless broadcast and multicast is a technology that transmits the same data from one data source to multiple targets through network resource sharing. With the development of mobile communication technology, wireless broadcast and multicast services based on mobile terminals have developed rapidly. At present, there are mainly three types of networks that can provide various types of broadcast and multicast services: [0003] (1) Realized by digital terrestrial broadcasting system, including DVB-H (Digital Video Broadcasting-Handheld) standard in Europe, ISDB-T standard in Japan and my country Mobile Multimedia Broadcasting (CMMB) standard proposed by China.
