Description

一种广播/組播业务控制信息的传输方法 A broadcast / multicast service control information transmission method

技术领域 FIELD

本发明涉及广播/组播服务技术,特别涉及基于单栽波实现广播/组播业务中的一种广播/组播业务控制信息的传输方法。 The present invention relates to a broadcast / multicast service technology, and more particularly to a single plant based on the method for transmitting broadcast waves implement a broadcast / multicast service / multicast service control information.

背景技术 Background technique

组播和广播是一种从一个数据源向多个目标传送数据的技术。 Multicast and broadcast are techniques for transferring data from a data source to multiple targets. 在传统移动通信网络中,小区组播业务或广播业务(CBS, Cell Broadcast Service )允许低比特率数据通过小区共享广播信道向所有用户发送,此种业务属于消息类业务。 In the conventional mobile communication network, a multicast service or a cell broadcast service (CBS, Cell Broadcast Service) allows low bit rate data through a cell shared broadcast channel to all users, messaging services such service belongs.

现在,人们对移动通信的需求已不再满足于电话和消息业务,随着因特网(Internet)的迅猛发展,大量移动多媒体业务涌现出来。 Now, the demand for mobile communications are no longer satisfied with telephone and message service, along with the Internet (Internet) the rapid development of a large number of mobile multimedia services emerge. 其中一些移动多媒体业务要求多个用户能同时接收相同数据,例如视频点播、电视广播、视频会议、 Some mobile multimedia services require multiple users to simultaneously receive the same data, such as video on demand, television broadcast, video conference,

网上教育、互动游戏等。 Online education, and interactive games. 这些移动多媒体业务与一般的数据业务相比,具有数据量大、持续时间长、时延敏感等特点。 Compared with the general data traffic of these mobile multimedia services, having a large amount of data, long time duration, delay sensitive and so on. 目前的网际协议(IP)組播和广播技术只适用于有线IP通信网络,不适用于移动通信网络,因为移动通信网络具有特定的网络结构、功能实体和无线接口,这些都与有线通信IP网络不同。 The current Internet Protocol (IP) multicast and broadcast IP technology is only applicable to a wired communication network, not applicable to a mobile communication network, since the mobile communication network has a specific network structure, function entities and wireless interfaces, which are wired communication with the IP network different.

为了有效地利用移动通信网络资源,第三代移动通信全球标准化组织(3GPP)提出了移动通信网络的MBMS,从而在移动通信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,尤其是空口接口资源。 To effectively utilize mobile communication network resources, the third generation mobile communication global standardization organization (3GPP) proposes an MBMS mobile communication network, thereby providing a data source sends data to a plurality of user-to-multipoint service in a mobile communication network , to share network resources, improve the utilization of network resources, especially air interface resources. 3GPP提出的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,这无疑顺应了未来移动数据发展的趋势。 MBMS 3GPP proposed not only to achieve a low rate of plain text messages multicast and broadcast, but also to achieve high-speed multicast and broadcast multimedia services, which undoubtedly conforms to the development trend of mobile data in the future.

图1为支持广播/组播业务的无线网络结构示意图,如图l所示,现有3GPP 中,支持广播/组播业务的无线网络实体为广播/组播业务服务器(BM-SC), BM-SC通过Gmb接口或Gi接口与关口GPRS支持节点(GGSN, Gateway GPRS Support Node)相连, 一个BM-SC可与多个GGSN相连;GGSN通过Gn/Gp 接口与服务GPRS支持节点(SGSN, Serving GPRS Support Node)相连,—个GGSN可与多个SGSN相连;SGSN可通过Iu接口与通用移动通信系统(UMTS ) 陆J4无线接入网(UTRAN )相连,然后UTRAN通过Uu接口与UE相连,SGSN 也可通过Iu/Gb接口与全球移动通信系统增强无线接入网(GERAN )相连,然后GERAN通过Um接口与UE相连。 1 a schematic configuration diagram of a wireless network to support broadcast / multicast service, as shown in FIG. L, the existing 3GPP, supporting broadcast / multicast service in a wireless network entity as a broadcast / multicast service server (BM-SC), BM -SC through Gmb interface or Gi interface with a gateway GPRS support node (GGSN, Gateway GPRS support node) connected to a BM-SC may be connected with a plurality of GGSN; GGSN via Gn / Gp interfaces with serving GPRS support node (SGSN, serving GPRS Support Node) is connected, - a GGSN may be connected to a plurality of SGSN; SGSN may be connected via an Iu interface with the universal mobile Telecommunications system (UMTS) terrestrial radio access network J4 (UTRAN), and is connected to UTRAN via the Uu interface and UE, SGSN also may be enhanced by wireless Iu / Gb interface and the GSM access network (GERAN) is connected, and then connected via GERAN Um interface and the UE. 其中,GGSN和SGSN属于无线网主备中核心网(CN)内的节点。 Wherein, GGSN and SGSN nodes within the wireless network belonging standby core network (CN).

从图1给出的网络结构可以看出,为了支持MBMS业务,在第三代移动通信系统中增加了移动网功能实体—广播组播业务中心,即BM-SC,所述BM-SC 为内容提供者的入口,用于授权和在移动网中发起MBMS业务,并按照预定时间计划传送MBMS内容。 Given network structure can be seen from Figure 1, in order to support the MBMS service, the mobile network function entity increase in the third generation mobile communication system - broadcast multicast service center, i.e. BM-SC, the BM-SC content provide access to those who, for authorizing and initiating MBMS service in the mobile network, and transmits MBMS content according to a predetermined schedule. 此外,在UE、 UTRAN、 GERAN、 SGSN、 GGSN等功能实体上增加了与MBMS相关的功能。 In addition, in the UE, UTRAN, GERAN, SGSN, GGSN and other functional entities associated with increased MBMS function.

MBMS包括组播模式和广播模式,其中组播模式需要用户签约相应的組播组,进行业务激活,并产生相应的计费信息。 MBMS includes multicast mode and broadcast mode, the multicast mode requires the user subscription corresponding multicast group, a service activation, and generates corresponding billing information. 由于组播模式和广播模式在业务需求上存在不同,导致各自的业务流程也不同,如图2和图3所示,图2为MSMS组播模式的业务流程示意图,图3为MSMS广播模式的业务流程示意图。 Since the multicast mode and broadcast mode exists on a different business requirements, leading to their different business processes, as shown in FIG. 2 and FIG. 3, FIG. 2 MSMS multicast mode is a schematic of a business process, FIG. 3 is a broadcast mode MSMS business process schematic.

如图2所示,MBMS组播业务涉及的处理过程包括:签约(Subscription )、 月艮务宣告(Service announcement )、用户力口入(Joining )、会话开始(Session Start )、 MBMS通知(MBMS notification )、数据传送(Data transfer )、会话结束(Session Stop)和用户退出(Leaving)。 2, the process of MBMS multicast service includes: subscription (Subscription), Burgundy monthly service announcement (Service announcement), force the user into the mouth (Joining), a session start (Session Start), MBMS notification (MBMS Notification ), data transmission (data transfer), the end of the session (session Stop) and user exits (Leaving). 其中,签约过程用来建立用户与业务提供者之间的关系,让用户预先订阅所需的MBMS服务;服务宣告过程用于由BM-SC宣告当前能提供的服务,即通知用户MBMS业务的相关信息;用户加入过程即MBMS业务激活过程,UE在加入过程中,通知网络自身愿意成为当前组播组的成员,才姿收对应MBMS业务的数据,该加入过程会在网络和加入组播组的UE中创建记录UE信息的MBMS UE上下文;会话开始过程中,BM-SC准备好数据传输,通知网络建立相应核心网和接入网的承载资源;MBMS通知过程 Among them, the contracting process used to establish the relationship between the user and the service provider, allowing users to subscribe in advance the required MBMS service; service announcement process can be used to declare the services currently provided by the BM-SC, notify the user of the MBMS service-related information; the user process that is adding the MBMS service activation process, UE in the accession process, notify the network itself willing to become members of the current multicast group before they pose to close the corresponding MBMS service data, the process will be added to the network and join a multicast group create a record of the UE, UE information MBMS UE context; session start process, BM-SC is ready to transmit data, the network notifies the core network and the establishment of appropriate bearer resources of the access network; the MBMS notification procedure

用千由RNC通知UE MBMS组播会话即将开始;在数据传送过程中,BM-SC 通过会话开始过程中建立的承载资源将数据传输给UE, MBMS业务在UTRAN 和UE间传输时有两种模式:点对多点(PTM)模式和点对点(PTP)模式, PTM净莫式通过MBMS点到多点业务信道(MTCH )发送相同的凄t据,所有加入组播业务或对广播业务感兴趣的UE都可以接收,PTP模式通过DTCH逻辑信道发送数据,只有相应的一个UE可以收到;会话结束过程用于将会话开始过程建立的承载资源释放;用户退出过程使组内的订户离开组播组,即用户不再接收组播数椐,该过程会将相应MBMS UE上下文删除。 The RNC notifies the UE in thousands MBMS multicast session is about to begin; during data transfer, the bearer resources established by the BM-SC a session start procedure of the data transmission to the UE, when the MBMS transmission between UTRAN and the UE has two modes : multipoint (PTM) mode and a point to point (PTP) mode, the PTM MBMS point-by Morse net traffic channel (MTCH) transmit the same data desolate t, all participating multicast service or the broadcast service of interest UE can receive, the PTP mode by a logical channel DTCH data transmission, only a corresponding UE can receive; will release the end of the session for a session start process of establishing the bearer resources; a user exit procedure enables subscribers to leave a multicast group within a group , i.e. the user no longer receives the multicast noted in the number, the process will delete the corresponding MBMS UE context.

如图3所示,MBMS广播业务涉及的处理过程与MBMS组播业务类似, 只是在会话开始之前,不需要执行签约过程和用户加入过程,并且,在会话结束之后,不需要执行用户退出过程。 3, the MBMS broadcast service is similar to the process according to the MBMS multicast service, just before the session starts, the user need not be performed during the addition and the contracting process, and, after the end of the session, the user exits the procedure need not be performed.

在MBMS PTM传输模式中,相关的无线控制信息包括业务信息、接入信息、无线承载信息、频率层收敛(FLC)信息等,都由无线资源控制(RRC) 层通过逻辑信道,如MBMS点到多点控制信道(MCCH)发送。 In the PTM MBMS transmission mode, the control information includes associated radio service information, access information, radio bearer information, frequency layer convergence (FLC) information, by radio resource control (RRC) layer through a logical channel, such as MBMS point multipoint control channel (MCCH) sent. 通常,MCCH 信息是基于固定调度的方式来传送的,并且,为了提高可靠性和稳定性,UTRAN 会重复发送MCCH信息。 Typically, MCCH information is scheduled based on a fixed manner to the transmission, and, to improve reliability and stability, the UTRAN can repeat the MCCH information is transmitted. 图4为MCCH信息的传输调度图,如图4所示,重复发送MCCH信息的周期为重复周期(RP),完整的MCCH信息会根据重复周期被周期性的发送。 FIG 4 is a transmission scheduling of the MCCH information, shown in Figure 4, the MCCH information is repeatedly transmitted cycle repetition period (the RP), complete MCCH information is periodically transmitted according to a repetition period. 修改周期(MP)则被定义为整数倍的重复周期,在每一个修改周期内都要对MCCH信息进行修改。 Modification period (MP) is defined as an integer multiple of the repetition period of the MCCH information to be modified in every modification period. MBMS的接入信息可以根据接入信息周期被周期性的发送,并且,接入信息周期是重复周期的整数分割。 MBMS access information may be periodically transmitted in accordance with the access info period, and the access info period repetition period is an integer division. MCCH 调度对于所有业务是一致的。 MCCH scheduling for all services is the same.

MCCH信息又分成关键信息和非关键信息,其中,关键信息由MBMS邻小区信息(MBMS neighboring cell information )、MBMS业^/言息(MBMS service information )、 MBMS无线承栽信息(MBMS radio bearer information )組成,以重复周期和修改周期周期性地传输,关键信息在每个修改周期中不能改变;非关键信息是指MBMS接入信息(MBMS access information), 是在接入周期j进行传输的,接入信息可在任何时间修改,图4中黑色填充的方块代表变化信息。 MCCH information is divided into critical information and non-critical information, wherein the key information from the MBMS neighbor cell information (MBMS neighboring cell information), MBMS industry ^ / statement message (MBMS service information), MBMS radio bearing plant information (MBMS radio bearer information) composition, the modification period and repetition period to be transmitted periodically, the key information can not be changed in each modification period; refers to non-critical information is MBMS access information (MBMS access information), j is transmitted in an access cycle, then the information may be modified at any time, in FIG. 4 filled in black squares represent change information.

目前,MBMS系统是3GPP Release6版本的一个重要属性,换句话说就是, MBMS技术是附属于现有3G系统的,MBMS业务是通过现有的传输信道和物理信道来承载的,使用现有的频率和带宽等。 Currently, an important attribute of the MBMS system is 3GPP Release6 version, in other words, the MBMS belongs to the prior art 3G system, the MBMS service through the existing transmission channels and physical channels to carry using conventional frequency and bandwidth. 具体来说,参见图5所示,MBMS 业务的4是供可分为三个阶段(phase ): In particular, referring to FIG. 5, it is available for the MBMS service 4 can be divided into three phases (phase):

第一阶段是会话开始之前的时段,在此阶段,网络不提供任何MBMS业务, 用户可能在不断尝试读取MBMS通知信息,此阶段中,用户可以在任何时间加入任4可业务。 The first stage is a period before the start of the session, at this stage, the network does not provide any MBMS service, the user may continue to attempt to read the MBMS notification information, in this stage, the user may be added to any service at any time 4.

第二阶段是UTRAN从核心网接收到会话开始(Session Start)到UTRAN 为该业务建立无线承载(RB)为止。 The second stage is from the core network to the UTRAN receives a session start (Session Start) for the service to the UTRAN to establish a radio bearer (RB) so far. 在此阶段UTRAN会通知用户接收MBMS 业务以及对MBMS业务^^行计数(counting)过程,以^J夬定承载类型。 At this stage the UTRAN informs the user receiving the MBMS service and the MBMS ^^ line count (Counting) process to a given bearer type Jue ^ J. UE 在此阶段可以响应counting,接收MCCH控制信道以获取相关控制信息。 UE can respond at this stage counting, for receiving the MCCH control information related to the control channel.

第三个阶段是MBMS最为重要的阶段,在此阶段,用户开始接收MBMS 业务,直至UTRAN从核心网获得会话停止(Session Stop )。 The third stage is the most important stage MBMS, at this stage, the user starts receiving the MBMS service, UTRAN obtained until the session is stopped (Session Stop) from the core network.

在上述过程中,UTRAN是通过MBMS控制信道MCCH向UE发送MBMS 控制信息的。 In the above procedure, UTRAN sending MBMS control information to the UE by MBMS control channel MCCH. 由于现在的R6 MBMS是与WCDMA系统使用同一个载波频段(筒称载频),因此,MCCH信道上控制信息的传输是通过现有3G网络的载波频段进行的,即UE不存在选择载波频段接收MBMS控制信息的问题。 Because now R6 MBMS is a WCDMA system uses the same carrier frequency (carrier frequency, said cartridge), therefore, the MCCH is a channel for transmission of control information through the existing 3G network the carrier frequency, i.e., the UE selects carrier band reception absent MBMS control information in question.

具体的MBMS控制信息的描述,及其传输和UE接收方法如下: Specific description of the MBMS control information, and transmitting and receiving UE follows:

无论UE处于何种状态(idle, URA—PCH, CELL—PCH, CELL—FACH and CELL—DCH),只要是UE加入了MBMS业务,那么都需要接收与其业务相关的MCCH上承载的控制信息。 Regardless of the state control information is carried on as long as the UE joins the MBMS service, you will need to receive the MCCH associated with the business in the UE (idle, URA-PCH, CELL-PCH, CELL-FACH and CELL-DCH),.

如上所述,控制信息中分为关键信息和非关键信息。 As described above, the control information is divided into critical information and non-critical information. 其中接入信息是非关键信息,按照自己特有的接入信息周期传输;其它关键MCCH控制信息是周期传输的,周期包括修改周期和重复周期。 Wherein the access information is non-critical information, the access information of their own unique transmission cycle; other critical MCCH control information transmission period, a modification period and a repetition period includes period.

如果业务使用PTM承载方式传输的话,用户还需要接收MSCH信道,其上的传输具体在SCCPCH物理信道上传输的MBMS业务的调度信息。 If the PTM bearer mode transmission service, then the user also needs to receive channel MSCH, transmission on a specific SCCPCH scheduling information in the MBMS service transmitted on the physical channel.

UTRAN传输MBMS控制信息是以特殊的顺序进行的,以保证用户以最少的时间捕获MCCH上承栽的MBMS控制信息,以及不接收不需要的控制信息。 UTRAN transmits MBMS control information is carried out in a particular order to ensure that the user capture minimum time commitment planted on the MCCH MBMS control information, and control information do not receive unnecessary. UE需要接收的MCCH上承载的MBMS控制信息如图6所示,包含如下信 MBMS bearer UE needs to receive the MCCH control information shown in FIG. 6, comprising the letter

由于MBMS系统涉及到的业务类型相当多,从背景业务比如软件下载, 到实时业务,比如视频浏览等。 Since the MBMS system involves quite a lot of business types, such as software downloaded from the background traffic, real-time services, such as video browsing. 随着业务提供商(SP)的逐渐增多,业务数目会不断增大。 With the service provider (SP) is gradually increased, the number of traffic will continue to increase. 而目前MBMS是现有WCDMA系统的增强,它使用了现有WCDMA的资源,即使用了现有的传输信道和物理信道。 MBMS is present, enhance existing WCDMA system, which uses the existing resources WCDMA, i.e. using a conventional transport channels and physical channels. 其后果在于MBMS 占用了大量的现有无线资源。 The consequence is that MBMS take up a lot of existing wireless resources. 这样影响就存在于两方面: 一是现有的业务会受到极大的影响;而是MBMS可同时提供的业务类型受到了极大地限制。 This influence exists in two aspects: First, the existing business will be greatly affected; but at the same time MBMS service type provided by a greatly limited.

A^v目前来看,单独为MBMS分配一个下行载波是非常必要的。 A ^ v now, a separately allocated for the MBMS downlink carrier is necessary. 一方面可以解放现有系统的资源,便于系统的资源有效利用;另一方面从运营商的角度来讲,可以获得的利益远大于为设立单独载波频段付出的代价。 On the one hand we can liberate the resources of the existing system, to facilitate the efficient use of system resources; on the other hand from the operator's point of view, can get benefits far outweigh the cost for the establishment of a single carrier frequency band to pay.

因此引入新的载波频段承载MBMS业务,并与原有的MBMS载波协调工作将是一个解决空口对MBMS业务容量限制的好方法。 Therefore, the introduction of new carrier frequency carrying MBMS service, and with the original MBMS carrier coordination would be a good way to air interface for MBMS service capacity constraints resolved. 但是基于单载波 But based on a single carrier

频段MBMS系统的MBMS业务控制信息的发送和UE接收过程则还没有一个明确的实施过程。 MBMS system band control information for MBMS service transmission process and the UE has not received an explicit implementation.

具体实施方式 Detailed ways

为使本发明的目的、技术方案及优点更加清楚明白,以下参照附图并举实施例,对本发明进一步详细说明。 For purposes of this invention, the technical solution and merits thereof more apparent, with reference to the accompanying drawings and the following embodiments, the present invention is further described in detail.

本发明的这种广播/组播业务控制信息的传输方法,在为广播/组播分配专用载波频段的系统中,网络侧在广播/组播专用载波频段和/或非广播/组播专用载波频段上向UE发送广播/组播控制信息;准备接收广播/组播业务的UE,根据广播/組播控制信息在哪个载波频段上传输的情况,在广播/组播专用载波频段和/或到非广播/组播专用载波频段上接收广播/组播控制信息。 This invention is broadcast / multicast service control information transmission method, the system is a broadcast / multicast allocating a dedicated carrier frequency band, the dedicated carrier network in a broadcast / multicast dedicated carrier frequency band and / or non-broadcast / multicast transmitting the broadcast frequency bands to UE / multicast control information; ready to receive a broadcast UE / multicast service, the information transmission control in accordance with carrier band on which broadcast / multicast, broadcast / multicast dedicated carrier frequency band and / or to receiving a broadcast on a non-broadcast / multicast dedicated carrier frequency / multicast control information.

通常在为广播/组播业务分配专用载波频段的系统中,UE先获知广播/组播专用载波频段的信息。 Typically in a broadcast / multicast service carrier frequency band allocation system in a dedicated, UE to know the broadcast / multicast information-dedicated carrier frequency band. 在本发明中,UE可以预先记录广播/组播专用载波频段信息;还可以由网络侧在非广播/组播专用载波频段上,向UE发送广播/组 In the present invention, UE can be pre-recorded broadcast / multicast information dedicated carrier frequency bands; may also be on a non-broadcast / multicast dedicated carrier frequency band, transmit the broadcast to the UE by the network side / group

播普用载波频段信息,比如:网络侧可以在广播信道或控制信道上,按照广播信道或控制信道的传输周期,定时向UE发送广播/组播专用载波频段信息。 Pu broadcast band information carrier, such as: the network side may be on a broadcast channel or control channel, transmission period according to a control channel or a broadcast channel, the timing transmitting broadcast / multicast information dedicated carrier frequency band to the UE. 然后,UE可以根据记录的或接收到的该广播/组播专用载波频段信息,在需要时, 到广播/组播专用载波频段上接收MBMS控制信息。 Then, the UE may or recording the received broadcast / multicast information dedicated carrier frequency band, when necessary, to receive the MBMS control information on the broadcast / multicast dedicated carrier frequency.

本发明中,UE可以有多种方式获知控制信息在哪个载波频段上传输的情况。 In the present invention, UE can be a variety of ways known transmission control information on which carrier band. 例如以下三种方式: For example, the following three ways:

一、 UE根据接收控制信道的情况,来获知控制信息在哪个载波频段上传输的情况。 A, the UE according to the reception of the control channel, to know the information transmission control in which the carrier band. 具体来说,如果UE处于非广播/组播专用载波频段时,可以先在非广播/组播专用载波频段的控制信道上接收广播/组播业务控制信息,如果没有收到,则再到广播/组播专用载波频段的控制信道上接收广播/组播业务控制信息。 Specifically, if the UE is in a non-broadcast / multicast dedicated carrier frequency band to be broadcast on a control channel received first non-broadcast / multicast dedicated carrier frequency band / multicast service control information, and if not received, then the broadcast / multicast control channel on a dedicated carrier frequency band receiving broadcast / multicast traffic control information. 如果UE处于广播/组播专用载波频段时,可以先在广播/组播专用载波频段的控制信道上接收广播/组播业务控制信息,如果没有收到,则再到非广播/组播专用载波频段的控制信道上接收广播/组播业务控制信息。 If the UE is in a broadcast / multicast dedicated carrier frequency band to be broadcast on a control channel received first broadcast / multicast dedicated carrier frequency band / multicast service control information, and if not received, then the non-broadcast / multicast dedicated carrier receiving a broadcast on a control channel frequency bands / multicast service control information. 这种方式下,UE比较盲目,有时需要在非广播/组播专用载波频段和广播/组播专用载波频段之间多次来回切换,可能会浪费UE的系统资源。 In this way, more blind UE, it is sometimes necessary non-broadcast / multicast dedicated carrier frequency band and the broadcast / multicast a plurality of times back and forth between a dedicated carrier frequency band, the UE may waste system resources.

二、 网络侧与UE预先设定在广播/组播专用载波频段和/或非广播/组播专用栽波频段上发送广播/组播控制信息,UE记录该设定;UE根据记录的设定, 获知控制信息在哪个载波频段上传输的情况,到对应的载波频段上接收广播/ 组播业务控制信息。 Second, the network side and the UE is set in advance on the broadcast / multicast dedicated carrier frequency and / or broadcast / multicast transmission dedicated frequency wave planted broadcast / multicast control information, recording the setting UE; UE recording setting learns the information transmission control in which the carrier band, carrier band to a corresponding receiving broadcast / multicast traffic control information. 这种方式下,UE接收的情况比较固定,如果网络侧改变频率下发广播/组播业务控制信息,需要UE.同时改变,实现不够灵活。 In this manner, the UE receives a relatively fixed situation, if the network side changes made broadcast frequencies / multicast service control information, UE needs. Changed simultaneously achieve not flexible enough.

三、 网络侧在非广播/组播专用载波频段和/或广播/组播专用载波频段上, 向UE发送在哪个载波频段上发送广播/组播控制信息的指示;UE根据该指示获知控制信息在哪个栽波频段上传输的情况,到对应的载波频段上接收广播/ 组播业务控制信息。 Third, the network side in the non-broadcast / multicast dedicated carrier frequency band and / or broadcast / multicast dedicated carrier frequency is sent to the UE sends a broadcast / multicast control instruction information on which carrier frequency; UE based on the control information indication informed which case planted in wave band transmission, to the corresponding carrier band receiving broadcast / multicast traffic control information. 这种方式下,网络侧只需向UE发送一个指示,如果网络侧改变频率下发广播/组播业务控制信息,UE只要根据指示改变即可,因此实现灵活,不需要多次在非广播/组播专用载波频段和广播/组播专用载波频段之间来回切换,减少UE的系统资源浪费。 In this way, the network side transmits to the UE an indication only, if the broadcast / multicast service control information sent by the network side changes the frequency, as long as the UE according to an instruction to change, and therefore flexible, does not require multiple non-broadcast in / dedicated carrier frequency band and the multicast broadcast / multicast switch back and forth between the dedicated carrier frequency band, to reduce waste of system resources of the UE. 实际应用中,建议采用这种方式。 Practical applications, it is recommended this way.

本发明既可以应用在多媒体广播/组播业务(MBMS)中也可以应用在非多媒体的广播/组播业务中,处理方式相同。 The present invention can be applied both in a multimedia broadcast / multicast service (MBMS) may also be used in non-multimedia broadcast / multicast service, the same treatment.
