Single-carrier frequency broadcast structure and method for implementing its business transmission

Abstract

This invention discloses an independent carrier frequency structure, in which, independent carrier-fequency broadcast network and mobile comunication network are connected by gateway, when a stream media service is transmitted, the BM-SC in the independent network utilizes a mobile communication network to distribute the service to node BNB in the independent network by the gateway, node BNB processes the stream media service and sends it to the UE. This invention also discloses a method for transmitting service of the independent broadcast structure.

Description

technical field [0001] The invention relates to multicast / broadcast technology, especially to a single carrier frequency broadcast architecture and a method for realizing service transmission. Background technique [0002] Multicasting and broadcasting are techniques for delivering data from one source to multiple destinations. In a traditional mobile communication network, a cell multicast service or a cell broadcast service (CBS, Cell Broadcast Service) allows low bit rate data to be sent to all users through a cell shared broadcast channel, and this service belongs to a message service. [0003] Now, people's demand for mobile communication is no longer satisfied with telephone and message services. With the rapid development of the Internet (Internet), a large number of mobile multimedia services have emerged. Some of these mobile multimedia services require multiple users to receive the same data at the same time, such as video on demand, TV broadcasting, video confere...

AI Technical Summary

Problems solved by technology

[0011] 1) Since the networking scheme of the single-carrier broadcast network is separated from the existing mobile communication network, the existing single-carrier broadcast network cannot utilize the network resources of the existing mobile communication network, but needs to re-establish a communication network to transmit broadcast services , thereby increasing the network construction cost;

[0012] 2) Since the independent carrier-frequency broadcast network has no uplink resources, the types of services broadcast are limited. For example, interactive services are difficult to implement in the existing independent carrier-frequency broadcast network, and multicast services cannot be realized

[0013] 3) The charging mechanism is single, only the monthly subscription system can be used, and the flexible billing based on traffic cannot be used
