Method of transmitting multimedia broadcast/multicast service in IP wireless access network

Abstract

The present invention discloses a method which issues a multi-media broadcast or multicast serving (MBMS) service in an IP radio access network (RAN). The method comprises that a radio network controller sends sending control information to a correspondent base station, and the base station issues the (MBMS) service data from the radio network controller and sent in a multicast form at the Iub interface according to the received sending control information. Since the MBMS service data is issued by adopting the multicast form in an IP bearing network, for the same MBMS service, the radio network controller just needs to issue once to all the base stations, the base station gets the MBMS service data from the assigned position in the network according to the received sending control information, and the MBMS service data is issued through an appointed channel which is used to send the MBMS service data at the correspondent primary area. In this way, for the same MBMS service data, the RNC just needs to issue once to all the NodeB which are controlled by the radio network controller (RAN). The bandwidth of the Iub interface is greatly saved, the burden of the network is lightened, and the investment of the operator is reduced.

Description

Method for issuing multimedia broadcast / multicast service in IP wireless access network technical field The present invention relates to broadcast / multicast technology, in particular to a method for sending Multimedia Broadcast / Multiple Broadcast Service (MBMS, MediaMultipleBroadcastService) services through an Iub interface in an Internet Protocol (IP) Radio Access Network (RAN). Background technique Multicasting and broadcasting are techniques for delivering data from one source to multiple destinations. 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 conferencing, online education, and interactive games. Compared with general data services, these ...

Problems solved by technology

From the point of view of the existing methods of issuing MBMS services through the Iub interface, for the same MBMS service data, each NodeB or even each cell under the jurisdiction of each NodeB must be sent once, which greatly wastes bandwidth, increases the burden on the network, and improves operator's investment
