技术领域 FIELD

[0001] 本发明属于通信领域,尤其涉及宽带码分多址(Wideband Code DivisionMultiple Access, WCDMA)移动通信系统中,控制多媒体广播组播业务(MultimediaBroadcast Multicast Service, MBMS)频率层汇聚的方法及系统。 [0001] The present invention belongs to the field of communications, in particular (Wideband Code DivisionMultiple Access, WCDMA) wideband code division multiple access mobile communication system according to the control multimedia broadcast multicast service (MultimediaBroadcast Multicast Service, MBMS) Method and system for frequency layer convergence.

背景技术 Background technique

[0002] MBMS业务是一种共享网络资源,从一个数据源向多个目标传送数据的技术。 [0002] MBMS service is a shared network resource, technical data is transferred from one data source to multiple targets. 为了有效地利用移动网络资源,第三代伙伴组织计划(Third Generation PartnershipProjects, 3GPP)在R6版本中提出了MBMS业务,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,实现网络资源共享,提高网络资源的利用率,尤其是提高了宝贵的空中接口资源的利用率。 In order to effectively utilize mobile network resources, the Third Generation Partnership Program Organization (Third Generation PartnershipProjects, 3GPP) proposes MBMS service in R6 version, which provides a data source in the mobile network to send data to multiple users multipoint business, to share network resources, improve the utilization of network resources, in particular to improve the utilization of valuable air interface resources. MBMS不仅能实现纯文本低速率的消息类组播和广播,而且还能实现高速多媒体业务的组播和广播,提供多种丰富的视频、音频和多媒体业务,这无疑顺应了未来移动数据发展的趋势,为移动通信的发展提供更好的业务前景。 MBMS not only can achieve a low rate of plain text messages multicast and broadcast, but also to achieve high-speed multicast and broadcast multimedia services, offers a variety of rich video, audio and multimedia services, which undoubtedly conforms to the development of future mobile data trend, providing better business prospects for the development of mobile communications.

[0003] 图1是MBMS业务系统的结构模型图,该MBMS业务系统包括用户设备101 (UserEquipment, UE),分别通过Uu接口102和Um接口103接入到通用地面无线接入网 [0003] FIG. 1 is a structural model diagram of MBMS service system, the MBMS service system includes a user equipment 101 (UserEquipment, UE), respectively, over the Uu interface 102 and the Um interface 103 access to a universal terrestrial radio access network

104 (Universal Terrestrial Radio Access Network, UTRAN)和GSM/EDGE 无线接入网 104 (Universal Terrestrial Radio Access Network, UTRAN) and GSM / EDGE Radio Access Network

105 (GSM/EDGE Radio Access Network,GREAN)。 105 (GSM / EDGE Radio Access Network, GREAN). 而GSM/EDGE 无线接入网105 与GPRS 服务支持节点106 (Serving General Packet Radio Service Support Node, SGSN)通过Iu/Gb接口107连接。 And GSM / EDGE radio access network 105 and the serving GPRS support node 106 (Serving General Packet Radio Service Support Node, SGSN) via Iu / Gb interface 107. 小区广播中心108 (Cell Broadcast Center, CBC)作为通用地面无线接入网104 和GPRS 网关支持节点/ 端点段111 (General Packet Radio Service GatewaySupport Node/Termination Point Fragement,GGSN/TPF)共同的小区广播中心。 Cell Broadcast Center 108 (Cell Broadcast Center, CBC) as universal terrestrial radio access network 104 and the gateway GPRS support node / end segment 111 (General Packet Radio Service GatewaySupport Node / Termination Point Fragement, GGSN / TPF) common cell broadcast center. 归属位置寄存器109 (Home Location Registrar, HLR)接入到GPRS服务支持节点106。 The home location register 109 (Home Location Registrar, HLR) access to the serving GPRS support node 106. 服务提供商/组播广播中心110和开放业务接入/业务使用者系统114 (Open Service Access/ServiceConsumer System, 0SA/SCS)均接入到广播组播业务中心115 (Broadcast MulticastService Center,BM-SC)。 Service provider / multicast broadcast center 110 and the Open Service Access / service user system 114 (Open Service Access / ServiceConsumer System, 0SA / SCS) have access to the broadcast multicast service center 115 (Broadcast MulticastService Center, BM-SC ). 该MBMS业务系统外接入到公用数据网络116 (Public DataNetwork, PDN)以及其他移动网络的服务提供商/组播广播中心117,公用数据网络116可以是Internet网络。 The outer MBMS service system access to the public data network 116 (Public DataNetwork, PDN) and other mobile network service provider / multicast broadcast center 117, public data network 116 may be the Internet. 图1中的Gmb 112、Gi 113参考点为广播组播业务中心115与GGSN/TPF111之间的接口,其中,Gmb 112接口提供控制面功能,Gill3接口提供用户面功能。 FIG 1 Gmb 112, Gi 113 the reference point as an interface between the broadcast multicast service center 115 and the GGSN / TPF111, wherein, Gmb 112 interface provides a control plane function, Gill3 interface provides the user plane function.

[0004] 广播组播业务中心115是新增的移动网功能实体,它是内容提供者的入口,用于授权和在移动网中发起MBMS承载业务,并按照预定时间计划传送MBMS内容。 [0004] The broadcast multicast service center 115 is a new mobile network functional entity, which is the content provider inlet for authorizing and initiating MBMS bearer service in the mobile network, and transmitting the MBMS content according to a predetermined program time. 对于已有的WCDMA分组网功能实体:GPRS网关支持节点105、GPRS服务支持节点106、无线接入网(Radio Access Net, RAN)以及用户设备101也需要增加MBMS相关功能和过程。 For the existing WCDMA packet network functional entities: GPRS gateway support node 105, GPRS support node 106, radio access network (Radio Access Net, RAN) and user equipment 101 may also need to increase the MBMS-related functions and processes.

[0005] MBMS业务在RAN中发送时,可以同时在多个频点上发送,而且在每个频点上的内容是相同的,如果将多个频点上接收同一个MBMS业务的UE都汇聚到其中的一个频率层上,其他频率层就可以不分配该MBMS业务的资源。 [0005] When the MBMS service transmitted in the RAN may be simultaneously transmitted on multiple frequency points, and at each frequency the content is the same, if receiving the same MBMS service the UE converge multiple frequencies a frequency layer to which, on the other frequency layer of the MBMS service can not be allocated resources. 为此,MBMS引入了频率层汇聚的技术,即在频率资源许可的情况下,RAN使用单独频点承载MBMS业务,并在其他频点上通知UE汇聚到指定的频点去接收MBMS业务,从而大大节省无线资源,减少由于MBMS占用资源而对小区内的其他业务造成影响。 For this reason, the introduction of MBMS frequency layer convergence technology, i.e., in the case where frequency resources permit, the RAN using a separate frequency to bear MBMS service and notifies the UE converging to the specified frequency to receive MBMS services on other frequencies, thereby saves radio resources, reduce the MBMS footprint and impact on other businesses in the area.

[0006] 频率层汇聚是一种无线资源优化管理的方法,根据业务属性、业务的服务区域以及用户分布等的不同,有些业务可能需要进行频率层汇聚,而有些业务为了保证所有的UE都能正常的接收,则不能进行频率层汇聚。 [0006] frequency layer convergence is a wireless resource optimization of management methods, depending on the service attributes, service areas and distribution business and other users, some businesses may need to make frequency layer convergence, and some businesses in order to ensure that all of the UE can normal reception frequency layer convergence can not be performed. RAN作为提供承载的部分,并不知道业务层面的信息,因此由核心网(Core Network,CN)来决定MBMS业务是否需要进行频率层汇聚比较合理,而频率层汇聚的操作由RAN来执行,即RAN根据各频点中无线资源的实际情况来选择业务汇聚的频点。 RAN provided as part of the carrier did not know information service level, thus determined by the core network (Core Network, CN) whether an MBMS service needs to be reasonable frequency layer convergence, and the frequency layer convergence operation performed by the RAN, i.e., RAN frequency selected service convergence according to the actual situation of the radio frequency resources.

[0007] 根据目前3GPP协议,SGSN在MBMS会话开始流程中可以要求RAN禁止频率层汇聚,则RAN在建立MBMS承载时不做频率层汇聚,如果SGSN未对频率层汇聚做任何要求,则由RAN决定是否进行频率层汇聚。 [0007] According to the current 3GPP protocol, SGSN in the MBMS session start process may require the prohibited frequency layer convergence RAN, the RAN is not established when the frequency layer convergence MBMS bearer if the SGSN does not make any frequency layer convergence of the claim, by RAN determine whether the frequency layer convergence.

[0008] 图2示出了现有技术中控制MBMS业务的频率层汇聚的方法流程,包括以下步骤: [0008] FIG. 2 shows a prior art control the MBMS frequency layer convergence procedure method, comprising the steps of:

[0009] 步骤201中,BM-SC决定发起MBMS会话开始流程,通知下游的GGSN节点会话开始,该会话开始通知中不携带频率层汇聚指示信息。 [0009] In step 201, BM-SC decides to initiate a MBMS session start procedure, inform GGSN node downstream of the start of the session, the session start notification does not carry the information indicating frequency layer convergence.

[0010] 步骤202中,GGSN节点建立MBMS承载上下文后,通知下游的SGSN节点会话开始,该会话开始通知中不携带频率层汇聚指示信息。 [0010] In step 202, GGSN node establishes the MBMS bearer context, SGSN node notifies the downstream session starts, the session start notification does not carry the information indicating frequency layer convergence.

[0011] 步骤203中,SGSN节点建立MBMS承载上下文后,根据一定的规则设置频率层汇聚指示信息,如果禁止频率层汇聚,则设置指示信息为禁止频率层汇聚,否则不设置频率层汇聚指示信息。 [0011] Step 203, SGSN node establishes MBMS the bearer context, the convergence indication information according to a certain rule setting frequency layer, if the prohibited frequency layer convergence, the set indication information to disable the frequency layer convergence, or not to set the frequency layer convergence indication information . 协议未定义SGSN节点设置频率层汇聚指示信息的具体规则,由SGSN节点自定义实现。 Protocol defined SGSN node sets the frequency layer convergence of the indication information specific rules, implemented by a custom SGSN node.

[0012] 步骤204中,SGSN节点通知下游的RAN会话开始,会话开始通知中可能携带频率层汇聚指示信息。 [0012] In Step 204, SGSN downstream node informs RAN session start, a session start notification may carry information indicative of the frequency layer convergence. 如果SGSN禁止频率层汇聚,则会话开始通知中携带频率层汇聚指示信息且指示为禁止频率层汇聚,否则会话开始通知中不携带频率层汇聚指示信息。 If the SGSN prohibit frequency layer convergence, the session start notification carries information indicating frequency layer convergence and indicating to prohibit frequency layer convergence, otherwise the session start notification does not carry the frequency layer convergence instructions.

[0013] 步骤205中,RAN根据会话开始通知中的频率层汇聚指示信息做不同处理,若指示信息禁止频率层汇聚,则执行步骤206 ;而若会话开始通知中未携带频率层汇聚指示信息,则执行步骤207。 [0013] In step 205, RAN aggregation indicating the frequency layer session start notification information do different processing, if the information indicating the prohibited frequency layer convergence, step 206 is performed; and when the session start notification does not carry the frequency layer convergence indication information, step 207 is executed.

[0014] 步骤206中,RAN建立MBMS承载时不进行频率层汇聚。 [0014] Step 206 is not performed when the frequency layer convergence RAN to establish MBMS bearers.

[0015] 步骤207中,RAN建立MBMS承载时自行决定是否进行频率层汇聚,可以汇聚,也可以不汇聚。 [0015] In Step 207, when the MBMS bearer establish RAN to decide whether a frequency layer convergence, convergence may, or may not converge.

[0016] 由此可以见,在现有技术中由SGSN节点设置频率层汇聚指示信息,而SGSN节点是不能获得业务层面的完整信息,也不能获得RAN侧无线资源的实际使用情况的,因而由SGSN节点进行MBMS业务的频率层汇聚判决是不合适也不准确的,这很可能产生错误的频率层汇聚控制,对不能进行频率层汇聚的业务执行了频率层汇聚而导致部分UE无法接收业务,或者对需要频率层汇聚的业务未执行频率层汇聚而浪费了RAN侧的无线资源,降低了无线资源的使用效率。 [0016] It can be see, converge in the prior art is provided by the SGSN node information indicating frequency layer, the SGSN node can not obtain complete information on the operational level, the actual use can not be obtained RAN side radio resources, thus the SGSN nodes of the MBMS frequency layer convergence judgment is inappropriate and inaccurate, it is very likely wrong frequency layer convergence control can not be performed on the frequency layer convergence of business and led to some frequency layer convergence UE can not receive the service, or the need for frequency layer convergence service convergence layer performs a frequency not wasted radio resources of the RAN side, decreasing the efficiency of use of radio resources.
