本发明涉及通信领域， 尤其涉及一种多媒体广播多播业务的测量上报 方法及系统。 背景技术
长期演进（Long Term Evolution, LTE ) 网络， 如图 1所示， 由演进全 球陆地无线接入网 (Evolved Universal Terrestrial Radio Access Network, E-UTRAN)和演进分组交换中心 （ Evolved Packet Core, EPC )组成， 网络 呈现扁平化。 EUTRAN通过 S1接口与 EPC相连。 其中， EUTRAN由多个 相互连接的演进基站 （Evolved NodeB, eNB )组成， 各个 eNB之间通过 X2接口连接； EPC由移动性管理实体（ Mobility Management Entity, MME ) 和服务网关实体 ( Serving Gateway, S-GW )组成。
为了有效地利用移动网络资源， 3GPP (3rd Generation Partnership Project, 第三代合作伙伴计划）提出了多媒体广播多播业务（Multimedia Broadcast Multicast Service, MBMS ), 并在 LTE系统中提出了增强的演进 型 MBMS业务 E-MBMS ( Evolved MBMS ), 在 LTE系统中 E-MBMS的逻 辑架构如图 2所示， MBMS业务在核心网中由 E-MBMS网关负责处理， 它 由控制面和用户面功能组成， 这两部分功能可能实现于不同的网络实体。 E-UTRAN分别与 MBMS用户面和控制面连接， 其中多小区 /多播协同实体 ( Multi-cell/multicast Coordination Entity, MCE )是接入网为实现多小区传 输（即使用 MBSFN传输方式） 而引入的逻辑实体， MCE既可以作为某些 功能实体（如 eNodeB )的一部分， 也可以是一个独立的实体。 在核心网内 MBMS 网关通过演进型广播和多播业务中心 (evolved Broadcast / Multicast Service Center, eBM-SC) 与内容提供方相连。 对于内容提供方， eBM-SC 是 MBMS业务内容的入口； 对于承载网络， eBM-SC提供 MBMS业务的管 理功能。
MBMS业务是一种从一个数据源向多个目标传送数据的技术， 实现了 网络（包括核心网和接入网） 资源的共享， 提高了网络资源 （尤其是空中 接口资源 ) 的利用率。 3GPP定义的 MBMS不仅能够实现纯文本低速率的 消息类组播和广播， 而且还能够实现高速多媒体业务的广播和组播， 为用 户设备 ( User Equipment, UE )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 3G的发展提供了更好的业务前 景。
在所述的 3GPP MBMS中 , MBMS业务可以釆用多播方式发送，根据 具体的发送和接收方式的不同， 所述 MBMS业务的多播方式又分为： 单频 网多播广播 MBSFN ( Multicast/Broadcast over Single Frequency Network )方 式和软合并方式。 其中：
MBSFN发送方式中， 基站网元在多个小区釆用相同的调制编码格式， 釆用相同的物理资源发送相同的物理信号，釆用相同的物理资源和 MBSFN 发送模式发送相同 MBMS 业务信号的多个小区构成了一个 MBSFN 区域 ( MBSFN area )。 MBMS多小区传输的特征包括： 1 )在 MBSFN 区域内同 步传输； 2 ) 支持用户终端合并接收来自多个小区的 MBSFN信号， 提高接 收信号的增益。现有技术中 MBSFN发送模式应用于 LTE系统中的 MBMS、 UMTS ( Universal Mobile Telecommunications System, 通用移动通信系统 ) 系统中专用载频的 MBMS发送。
在 LTE系统中，一个 MBMS业务映射到一条 MTCH ( Multicast traffic Channel, 多播业务信道）。 多个 MTCH信道可以通过动态复用的方式时分 复用的映射到 MCH ( Multicast Channel, 多播信道） 传输信道上； 一个或 多个 MBSFN Area中每条 MCH/PMCH ( Physical Multicast Control Channel, 物理多播信道 ) 的配置信息， 包括每个 PMCH信道配置的 MBSFN子帧配 置、 调制编码方案等等承载在多播控制信道（Multicast Control Channel, MCCH )上， 在实际的 LTE组网中， 一个 MBSFN区域上有若干个 MBSFN 业务， 具备相同的 MBSFN区域的多个 MBSFN业务的数据信道 MTCH, 以及该 MBSFN业务的多播控制信道 MCCH可以复用到一条或多条多播信 道 MCH。在传输中根据业务 QoS的不同， 不同的业务映射到不同的 MCH, 每个 MCH配置独立的 MCS调制编码方案（ Modulation and Coding Scheme, MCS ), 映射有 MCCH的 MBSFN子帧配置有 MCCH 专用的 MCS信息。
为了提高 MTCH的发送效率， 每个 MCH上承载的多个 MTCH可以釆 用动态调度的方法， 通过动态调度可以将 2个或 2个以上的 MTCH复用在 同一个 MBSFN子帧上并占用该子帧的部分资源。在一个调度时机中可以发 送多个 MTCH和动态调度信息（dynamic schedule information, DSI ), 其中 调度信息携带 MTCH到辅助 MBSFN子帧的映射信息， 这种映射信息借助 于在一个调度周期内的 MBSFN子帧编号索引关系确定， UE读取调度信息 可以知道每个 MTCH被分配在哪些 MBSFN 子帧上， UE 可以在相应的 MBSFN子帧上读取其感兴趣的 MTCH,而忽略它不需要读取的 MBSFN子 帧， 从而提高 UE的 MBMS业务接收效率， 节省 UE的电能消耗。
除了在 LTE系统， 在 UMTS系统中也有 MBMS业务， 在 UMTS网络 中， 基站网关到核心网之间的接口为 Iu接口。 基站（ NodeB )通过无线网 络控制器 （Radio Network Controller, RNC )与核心网 （ CN )连接， RNC 与 CN之间的接口为 Iu接口，基站与无线网络控制器 RNC之间的接口为 Iub 接口。 而 RNC之间也可以存在直接接口， 称为 lur接口。 在核心网内部又 有若干功能实体， 比如网关 GPRS支持节点 (Gateway GPRS Support Node, GGSN)、 业务 GPRS支持节点 （Service GPRS Support Node, SGSN )等。 其网络架构依附于已有的 3G网络架构。 主要的改进包括两方面： 一方 面， 通过增加新的功能实体广播组播业务中心（BM-SC)来提供与管理 MBMS业务； 另一方面是在已有的功能实体比如在 GGSN、 SGSN上， 增 加对 MBMS业务的支持。
MBMS作为运营商为用户提供的一项网络业务， 需要保证整个业务的 覆盖以及服务质量， 即运营商需要及时知道在当前网络中 MBMS业务是否 可以满足用户需求。 运营商收集该信息的方法基本上有收集用户的投诉或 者在网络部署过程中投入大量人力物力去执行路测（Drive Test ), 以便收集 所有性能参数。 但是这些都会给运营商带来大量的损失或成本支出。 因此 如果 MBMS的业务性能可以通过 UE自动上 的话， 那就可以解决上述问 题。 而最小化路测 （Minimization of drive tests, MDT )正是在此需求下产 生的一个运营商在下一代通信网络中关心的重要功能， 而且也是下一代移 动网络组织（Next Generation Mobile Network, NGMN )的重要需求， 其目 的就是为了减小在网络部署中因为路测而带来的网络运营成本和以及提升 网络维护效率， 而需要 UE代替之前的部分人工路测功能，执行网络性能的 测量上报功能。 发明内容
