Description

多播组播业务的实现方法 Multicast implementation Multicast service

技术领域 FIELD

本发明涉及多播组播业务技术领域,特别是指一种多播组播业务的实现方法。 The present invention relates to an MBMS technology, and particularly the method for implementing multicast service refers to a multicast.

背景技术 Background technique

在3GPP系统的一些应用场合中,需要NodeB向小区覆盖范围内的多个用户发送相同的数据信息,即多播组播业务。 In some applications the 3GPP system, the NodeB needs to transmit the same data to a plurality of users within the cell coverage, i.e. MBMS. 在现有3GPP系统中,通常采用专用物理信道或下行公共物理信道的方式来实现。 In the conventional 3GPP system, usually a downlink dedicated physical channel or physical common channel manner.

下面对这两种方式分别进行简要说明: Here are these two ways brief description:

首先,采用专用物理信道实现多播组播业务的方式具体是指:NodeB为接收特定频道业务的各个用户分配供其各自使用的专用物理信道,在所分配的专用物理信道上传送该频道的相同的业务数据。 First, using a dedicated physical channel implementation MBMS specifically refers to: NodeB for a dedicated physical channel each use is allocated to each user to receive a particular channel service, transmits the same to the channel in the dedicated physical channel allocated business data. 也就是说,即使多个用户共享一个频道的业务信息,也需要通过多个专用信道来传送数据。 That is, even if a plurality of users to share business information channel, also need to transmit data via a plurality of dedicated channels. 这种方式实现简单,比较适用于多播组播业务用户数不太大的情况,当多播组播业务用户数较大时,会消耗大量的码资源和功率资源。 Simple, more suitable for MBMS the number of users is not large, when the number of large MBMS user will consume a large amount of code resources and power resources in this way.

其次,采用下行公共物理信道实现多播组播业务的方式具体包括:在NodeB側采用固定的发射功率发送业务数据,所有用户在相同的下行公共物理信道上接收相同的多播组播业务数据。 Secondly, the downlink common physical channel implementation of the MBMS comprises: a fixed transmission power in the NodeB side transmits service data, all users in the same downlink common physical channel receive the same MBMS data. 这种方式较之前述方式的优点是码资源利用率高,而且在通常情况下,为了保证绝大多数用户获得服务,发射功率基于网络规划中用户传播环境最差的情况进行设置,因此发射功率通常设置得较高。 In this manner the advantages of the embodiment are compared with high resource utilization code, but under normal circumstances, in order to ensure that the vast majority of users access to services, the transmit power is set based on the worst user in the network planning propagation environment, the transmission power so usually set too high. 这样一来,该方式就比较适用于用户数较大且部分用户分布在信道条件较差环境中的情况。 Thus, this method is more suitable for a larger portion of the user and the distributed environment poor channel condition in the case of the number of users. 而对于用户数不大且大多数用户分布在信道条件较好区域的情况来说,使用该方式无疑会造成发射功率的巨大浪费。 For small number of users and the majority of users spread across the channel conditions better regional situation, the use of which way it will cause a huge waste of transmit power. 由此可见,在通过以上两种方式实现多播组播业务时均存在资源不合理利用的问题。 Thus, irrational use of resources are a problem at the time of MBMS achieved by the above two methods.

发明内容 SUMMARY

有鉴于此,本发明的主要目的在于提供两种多播组播业务的实现方法, 实现保证业务质量的同时,解决现有多播组播业务实现方法中资源不合理利用的问题。 In view of this, the main object of the present invention is to provide two methods of MBMS, the guarantee of the quality of service at the same time, solve the problems of the prior MBMS realization in irrational use of resources.

而且,在上述NodeB通过HS-DSCH传输多播组播业务数据时,由于既传送多播组播业务数据的系统位数据,又传送多播组播业务数据的校验位数据,因此可以实现当UE根据接收到的系统位数据不能正确获取业务数据时, 可以进一步根据校验位数据来获取正确的业务数据。 Further, when the above-described MBMS NodeB HS-DSCH data transmitted through the transmission system since both the bit data of the MBMS data, and transmitting the multicast data parity bit multicast service data, can be achieved when the UE upon receiving the systematic bit data can not be acquired service data correctly, to obtain the correct further service data according to parity data. 另外,在通过HS-DSCH 传输业务数据的系统位数据和校验位数椐时,可以将系统位数据和校验位数据分别设置在固定的TTI位置进行传送,从而减小格式信息所占用的资源量,并且可以在多小区情况下,实现不同小区数据的软合并,提高系统增益。 Further, when the bit data through the system and check bits noted in the HS-DSCH transmission of service data, the system may be bit data and parity data are arranged in a fixed position transmission TTI, thereby reducing the occupied format information resources, and may be in a multi-cell case, to achieve soft combining data of different cells, to improve the system gain.

步骤203: NodeB通过HS-DPCCH接收UE发送的反馈信息,并根据该反馈信息判断是否存在需要重传的频道数据,如果是,则执行步骤204;否则,执行步骤205。 Step 203: NodeB receives the feedback information through the HS-DPCCH sent by the UE, based on the feedback information and determines whether there is the channel data to be retransmitted, if yes, execute step 204; otherwise, step 205 is executed.
