同步调度方法 Synchronization scheduling method

技术领域 FIELD

[0001] 本发明涉及通信领域,尤其涉及同步调度方法。 [0001] The present invention relates to communication field, and particularly relates to a synchronous scheduling method. 背景技术 Background technique

[0002] 随着通信技术发展,可以提供的移动数据速率越来越高,移动业务的应用形式也越来越多样化,除了满足电话、消息和手机上网浏览等业务外,还涌现出了大量的高带宽多媒体业务,如视频会议、电视广播、视频点播、广告、网上教育、互动游戏等。 [0002] With the development of communication technology, mobile data rates can be provided by increasing the application form mobile services are increasingly diverse, in addition to meeting the phone, messaging and mobile Internet browsing outside the business, but also the emergence of a large number of high-bandwidth multimedia services such as video conferencing, TV broadcasts, video on demand, advertising, online education, and interactive games. 其中有一类业务具有一个共同的特点:要求多个用户同时收到相同的业务。 One type services have a common characteristic: requires multiple users simultaneously receive the same service. 如天气预报、新闻、广告、资讯、 电视等。 Such as weather, news, advertising, information, television. 为了有效地利用移动网络资源,引入多媒体广播多播服务(Multimedia Broadcast MulticastService,以下简称MBMS),即在移动网络中提供一个数据源向多个用户发送数据的点到多点业务,实现移动核心网和接入网资源共享,提高网络资源的利用率,尤其是宝贵的空口接口资源。 For efficient use of mobile network resources, the introduction of multimedia broadcast multicast service (Multimedia Broadcast MulticastService, hereinafter referred to as the MBMS), i.e., a data source sends data to a plurality of user-to-multipoint services in a mobile network, the core network for mobile share and access network resources, improve network resource utilization, especially valuable air interface resources.

[0003] 为了提高小区容量,充分利用空口资源没,MBMS业务需要进行软合并,这就要求小区间的媒体数据在空口一致,且时间差(简称Delta CFN),保证在一个传输时间间隔(transmission time interval以下简称TTI)加一个时隙(以下简称Slot)内。 [0003] In order to improve cell capacity, full use of air interface resources not, the MBMS service requires soft combining, which requires the media data between the cells in the air same port, and the time difference (referred to as Delta CFN), to ensure that a transmission time interval (transmission time interval hereinafter referred to as TTI) plus one slot (hereinafter referred to as slot) inside. 引入MBMS 后,用户面的协议栈发生了变化,支持软合并的多个小区共享分组数据汇聚协议(packet data convergence protocol,以下简称PDCP)和无线链路控制(radio link control,以下简称RLC)实体,每个小区使用各自的MBMS的媒体接入控制(medium access control forMBMS,以下简称MAC-m)以及各自的帧协议(frame protocol,以下简称FP)。 After the introduction of the MBMS, user plane protocol stack changes, multiple cells support soft combining shared packet data convergence protocol (packet data convergence protocol, hereinafter referred to as PDCP) and radio link control (radio link control, hereinafter referred to as RLC) entity each MBMS cell using respective media access control (medium access control forMBMS, hereinafter referred to as MAC-m) and the respective protocol frames (frame protocol, hereinafter referred to as FP). 这样就有个问题:虽然在PDCP/RLC层面保证了小区间MBMS数据的同步,但是每个小区在MAC_m、FP 层面还是各自调度,这样就没法保证不同小区的空口无线帧的时差在ΙΤΤΙ+lSlot范围内。 Thus there is a problem: while in PDCP / RLC level to ensure the synchronization between MBMS data cell, each cell or each scheduling MAC_m, FP level, thus failing to ensure that the difference of different air interface cell radio frames ΙΤΤΙ + lSlot within range. 而FP的节点同步和传输信道同步,只能保证无线网络控制器(radio network controller, 以下简称RNC)和节点B(以下简称Node B)在Iub 口地面资源的同步,保证不了同一业务的数据在各个小区的FP也是同步的。 FP node and the synchronization channel transmission synchronization, only to ensure that the radio network controller (radio network controller, hereinafter referred to as RNC) and Node B (hereinafter referred to as Node B) in the Iub interface resource synchronization ground, can not guarantee that the data in the same service FP are synchronized with each cell. 因此,必须提供一种方式保证业务数据在不同小区的MAC-m和FP层面的同步。 Thus, a way must be provided to ensure the synchronization service data in different cells and FP MAC-m level.
