Embodiment Construction

[0025] A system and method for allocating adaptive broadcast-multicast wireless resources provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] image 3 An adaptive broadcast-multicast wireless resource allocation system according to an embodiment of the present invention is shown, such as image 3 As shown, the distribution system includes a mobile terminal, an operation and maintenance module (O&M) and a multi-cell multicast coordination entity (MCE). Wherein, the mobile terminal is located in the Broadcast Multicast Service Single Frequency Network (MBSFN), and the Multi-Cell Multicast Coordination Entity (MCE) is used to report the service reception status reported by each terminal in the MBSFN to the operation and maintenance module (O&M). Unicast and broadcast multicast load conditions and perform corresponding broadcast and multicast scheduling according to the designated broad...

Abstract

The invention provides a self-adaptive allocation system and a self-adaptive allocation method for broadcasting multicast radio resources. A multi-cell multicast coordination entity receives a user requirement for broadcasting multicast service; an operation maintenance module selects a proper unicast and multicast broadcasting resource division proportion according to the user requirement for the broadcasting multicast service received by the multi-cell multicast coordination entity, and the unicast user load condition; and the multi-cell multicast coordination entity self-adaptively allocates resources for the broadcasting multicast service based on the broadcasting multicast resource division proportion divided by the operation maintenance module. Due to the combination of actual requirement change of the unicast and multicast broadcasting users, the multi-cell multicast coordination entity flexibly triggers the operation maintenance module to perform corresponding unicast and multicast resource division. Therefore, the occurrence of conditions of resource waste and data packet loss is effectively reduced, and the service provision capacity of the system is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, the present invention relates to an adaptive broadcast multicast wireless resource allocation system and method. Background technique [0002] As the multimedia capabilities of mobile terminal devices become stronger and stronger, consumers are more and more interested in using services such as multimedia or mobile TV on mobile terminals. In Release 6 of the 3rd Generation Partnership Project (3GPP) , the low spectral efficiency of 0.02-0.2 (bit / s / Hz) in the broadcast multicast service (MBMS) can no longer meet the increasing user needs. In addition, under the pressure of other mobile phone broadcasting technologies (such as DVB-H and MediaFLO) in the market, 3GPP put forward new requirements for the E-MBMS evolution technology of the next generation wireless access network at the RAN28 plenary meeting, which needs to An evolution technology (LTE, Lo...
