Multicast broadcast service dispatching method

Abstract

This invention puts forward a multicast broadcast business scheduling method including: S202, appointing a primary base station in a multicast broadcast business region, and a scheduling framing unit of the station is responsible for finishing the schedule of multicast service in the entire region and transmitting the schedule andcontrol information of the service to other base stations in the multicast service region, S204, the scheduling and framing units of all base stations in the region carry out unified schedule together with single-cast connected control information based on the multicast control information and schedule information to execute single-cast schedule and MAC PDU, 206, the base station finishes framing of the physical layer and transmits it to at least one terminal.

Description

technical field [0001] The present invention relates to a wireless communication system, in particular to a multicast broadcast service scheduling method. Background technique [0002] MBS (Multicast and Broadcast Service, Multicast Broadcast Service) is an important function of a wireless communication system defined by the IEEE802.16e protocol. MBS is divided into two situations: single base station access and multi-base station access. The former refers to the multicast broadcast service in a base station, and the latter refers to the fact that all terminals registered to the multicast broadcast content at the network level can receive MBS services under the MBS area. A multicast broadcast service that is transmitted synchronously by all base stations on the downlink connection. The MBS involved in this article is the multicast broadcast service of multiple base stations. [0003] FIG. 1 is a block diagram of an end-to-end WiMAX network system in the NWG (Network Workin...

AI Technical Summary

Problems solved by technology

[0009] This patent can realize unified MBS service scheduling within the MBS Zone, and support all base stations under the MBS Zone to transmit the same data synchronously, thereby realizing the capability of MBS macro diversity. However, since unicast scheduling is completed on the base station, multiple The broadcast scheduling is completed at the access network gateway, so this solution also leads to the repeated implementation of the scheduling function in multiple places, and the unified scheduling of unicast and multicast broadcast services cannot be realized
