Description

多媒体广播組播业务中的异频 /异系统测量方法及测量时间设置装置 技术领域
本发明涉及第三代移动通信系统（3G, The 3rd Generation ) 中的终 端异频 /异系统测量处理技术， 尤其涉及一种多媒体广播组播业务 ( MBMS, Multimedia Broadcast/Multicast Service ) 中的异频 /异系统测量 方法及测量时间设置装置。
背景技术
通用移动通信系统 ( UMTS , Universal Mobile Telecommunications System )是采用 WCDMA ( Wideband Code Division Multiple Access, 宽 带码分多址） 空中接口技术的第三代移动通信系统， 主要是在 WCDMA/GSM ( Global System for Mobile Communications,移动通信全球 系统）全球标准化组织 3GPP ( Third Generation Partnership Project, 第三 代合作伙伴计划） 中发展。
其中在 3GPP UMTS标准中，根据无线资源控制（ RRC , Radio Resource Control )连接是否建立， 可以将用户终端（ UE , User Equipment )分为空 闲 （ Idle )模式和 RRC连接 ( Connected )模式： 其中未与 UMTS通用陆 地无线接入网 （UTRAN, Universal Terrestrial Radio Access Network )建 立 RRC连接的用户终端处于 Idle模式， 该模式下的用户终端只能通过非 接入层（NAS, Non-Access Stratum )标识来区分， 如通过国际移动台识 别号 （IMSI, International Mobile Subscriber Identity )来区分； 其中已与 UTRAN建立 R C连接的用户终端处于 RRC Connected模式， 该模式下 的用户终端被分配无线网络临时标识（R TI, Radio network Temporary Identity ), 以作为该用户终端在公共传输信道上的标识。
而对于 RRC Connected模式的用户终端， 又可根据 RRC连接的层次 和用户终端能使用的传输信道类型将用户终端划分为不同状态： 其中 CELL— PCH状态、 CELL— FACH状态和 CELL_DCH状态下的用户终端在 小区层次上可以区分， URAJPCH状态下的用户终端在 UTRAN登记区 ( URA, UTRAN Register Area )层次上可以区分。 其中 CELL— DCH状态
确认本 下的用户终端被分配专用的物理信道， 用户终端可使用专用传输信道和 共享信道以及它们的组合； CELL— FACH状态下的用户终端在下行要连续 监控一个公共传输信道（FACH, Forward Access Channel ), 在上行被分 配缺省的公共信道（RACH, Reverse Access Channel ); CELL— PCH和 URA_PCH 状态下的用户终端采用不连续接收 （ DRX , Discontinuous Reception )方式通过相关的寻呼指示信道 ( PICH, Page Indicator Channel ) 监控一个寻呼信道 ( PCH, Page Channel ), 这两种状态下的用户终端没 有任何上行活动。
在 3GPP UMTS标准中， 当用户终端处于不同模式和状态时，要根据 接收的测量控制信息或系统信息和自身所处小区的接收质量对异频小区 进行测量， 以进行小区重选、 切换等处理。 其中处于 Idle, CELL— PCH, URA— PCH和 CELL—FACH状态下的用户终端对异频测量的触发条件是 接收的系统信息和当前所在小区的接收质量； 而处于 CELL— DCH状态下 的用户终端对异频测量的触发条件是系统下发的测量控制信息。 一般情 况下， 对于不具有双接收机的用户终端， 由于无法同时支持对两个不同 频率上的信号进行接收解码， 因此用户终端在进行异频测量期间会中断 对当前小区内信号的接收。
同时， 伴随着第三代移动通信技术的发展， 用户对移动通信业务的 需求已不再满足于语音业务， 由于第三代移动通信系统可以提供比第二 代移动通信系统更高的数据传输速率， 因此大量多媒体业务便涌现出来， 比如： 视频电话、 图片下载、 高速浏览 Internet网络等服务。 其中， 一些 应用业务要求多个用户能同时接收相同的数据， 比如： 视频点播、 电视 广播、 视频会议、 网上教育、 互动游戏等业务。
为了有效利用移动通信网絡资源， 第三代移动通信系统引入了组播 和广播的概念， 组播和广播业务是一种从一个数据源向多个目标传送相 同数据的技术。 由此， WCDMA/GSM全球标准化组织 3GPP提出了多媒 体广播 /组播业务 ( MBMS, Multimedia Broadcast/Multicast Service ), 所 谓 MBMS就是在移动通信网络中提供一个数据源向多个用户发送相同数 据的点到多点业务， 以实现网络资源共享， 提高网络资源的利用率， 尤 其是空口接口资源的利用率。
MBMS业务在用户终端和 UTRAN之间的数据传输模式可分为两种： 点到点（ PTP, Point to Point )模式和点到多点（ PTM, Point to Multipoint ) 模式。 其中 PTP模式用于 MBMS的组播模式， 组播模式下的 RRC连接 模式下的用户终端通过专用控制信道（ DCCH, Dedicated Control Channel ) 接收控制信息、 及通过专用业务信道（ DTCH, Dedicated Traffic Channel ) 接收数据信息。 而 PTM模式用于 MBMS的广播或组播模式， 该模式下 的用户终端通过 MBMS 点到多点业务信道 ( MTCH , MBMS point-to-multipoint Traffic Channel )接收数据信息、及通过 MBMS点到多 点控制信道 ( MCCH, MBMS point-to-multipoint Control Channel )接收控 制信息。
其中 MBMS业务在 PTM模式下的控制信息是通过 MCCH下发的， 在 MCCH上下发的 MBMS控制信息包括业务信息、接入信息和无线承载 信息等，为简单起见， 以下将在 MCCH上发送的 MBMS控制信息简称为 "MCCH信息"。 MCCH信息分为临界信息和非临界信息两种： 临界信息 包括 MBMS邻小区信息、 MBMS业务信息和 MBMS无线承载信息； 非 临界信息为 MBMS接入信息。
MCCH信息是基于固定调度发送的， 完整的 MCCH信息基于 "重复 周期" 被周期性的发送， 以提高接收可靠性。 而 "修改周期" 为 "重复 周期" 的整数倍， 临界信息只在修改周期内 MCCH信息第一次发送时可 以被修改; 在每个修改周期开始 UTRAN会发送 MBMS修改信息， 此修 改信息内包含在此修改周期内 MCCH信息被修改的 MBMS业务标识； MBMS修改信息在此修改周期内的每个重复周期至少重复一次； 而非临 界信息可以在任何时间被修改。 此外， MBMS接入信息基于 "接入信息 周期" 被周期性发送， "重复周期" 是 "接入信息周期" 的整数倍。 具体 如图 1所示为 UTRAN发送 MCCH信息期间的 "重复周期"、 "修改周期" 和 "接入信息周期" 之间的关系示意图。
其中对于修改周期、 接入信息周期、 重复周期的取值依次为： 修改周期一修改周期系数 m范围： （7...10)， 修改周期 MP=2m x帧 长。
接入信急周期一接入信息周期系数 a 范围： （0...3), 接入信息周期 AIP=(MP/2a) x帧长。
重复周期一重复周期系数 r范围： （0...3), 重复周期 RP=(MP/2r) x帧 长。
在小区内用户终端通过接收 MCCH信息来获取有关 MBMS业务的信 息，还通过接收 MCCH信息中的接入信息来获知感兴趣业务的接入信息， 基于该接入信息向 UTRAN发送 MBMS业务请求信息。
其中用户终端在 CELL_FACH状态下，定位满足下列公式的帧（ SFN, System Frame Number ), 并在满足该公式的帧执行异频测量：
SFN div N=C_R TI mod M— REP + n M— REP (公式 1 ) 其中：
N代表用户终端监控的承载非 MBMS逻辑信道的辅助公共控制物理 信道 ( SCCPCH, Secondary Common Control Physical Channel )上有最 大发射时间间隔（ TTI , Transmission Timing Interval )的 FACH的 TTI除 以 10ms;
M_REP代表测量间隔循环周期， M— REP = 2k; 由上式， 一个 N帧的 测量时间的重复周期是 N X M_REP帧；
其中 k是 FACH测量间隔循环周期系数， 在系统信息 11或 12所含 的信息元素 "FACH measurement occasion info" 中读取；
C_RNTI ( cell radio network temporary identity )是 UE的 C-RNTI值； n = 0，l，2...， 只要 SFN低于其最大值。
其中 N与 k的对应取值为：
Figure imgf000006_0001
这样， 用户终端按照上述公式（ 1 )计算得到满足条件的 SFN, 并在 满足条件的 SFN进行异频测量， 及在异频测量期间中断对当前小区 MBMS的接收。
由于 UTRAN下发 MCCH信息的 "接入信息周期"最小为 0.16s, 取 值范围内的值都是该最小值的倍数； 同时当用户终端在 CELL— FACH状 态下的 FACH TTI=10ms、 k=3时， 则按照上述公式（ 1 )计算异频测量时 间是每隔 80ms—次， 测量持续时间为 10ms。 由于这个原因的存在就可 能导致存在下列问题：
( 1 )某些用户终端的异频测量时间与 UTRAN下发 MCCH信息的时 间总是重叠， 则由于用户终端需要在这个重叠时间内进行异频测量， 从 而导致在这个重叠时间内用户终端总是接收不到重要的 MCCH信息。
( 2 ) 为了避免 （1 ) 中的问题， UTRAN 可以通过改变用户终端的
C-RNTI来避免用户终端异频测量时间总和 MCCH信息的下发时间重叠， 但是当进行异频测量的用户终端较多时， 考虑到每个小区内 MCCH信息 的下发时间点的差异， UTRAN要分别更改每个用户终端的 C-RNTI才可 以避免每个用户终端的异频测量时间总和 MCCH信息的下发时间重叠， 由此则可能会增加 UTRAN的分配调度复杂性。
其中用户终端在 Idle、 CELL—PCH和 URA— PCH状态下， 支持不连 续接收 （DRX ) 功能时， 执行异频测量时应该至少每隔 (Ncarrier-l) x TmeasureFDD时间进行测量异频。 其中参数 Ncarrier指测量的异频数目； 终端应至少使用两个异频测量值平均得到异频的测量值， 用于平均的异 频测量值中至少有两个测量值间隔至少为 TmeasureFDD/2。 相关参数具 体如下：
DRX cycle 0.08 0.16 0.32 0.64 1.28 2.56 5.12 length [s]
Tmeasure 0.64 (8 0.64 1.28 (4) 1.28 (2) 1.28 (1) 2.56 (1) 5.12 (1) FDD[s] DRX (4)
(number of cycles)
DRX cycles) 这样当用户终端处于 Idle、 CELLJPCH或 U AJPCH状态下支持 MBMS业务， 进行异频测量时， 用户终端要周期性进行异频测量处理以 得到异频测量值。 不具有双接收机的用户终端在进行异频测量过程中， 也会中断对当前小区 MBMS业务的接收。
由上表可见， 用户终端进行异频测量获得异频测量值的周期与
UTRAN下发 MCCH信息的周期存在倍数关系， 用户终端设置异频测量 采样点时间并没有考虑与 MCCH信息下发时间的关系； 因此也可能导致 用户终端进行异频测量的采样时间总和 MCCH信息的下发时间重叠， 由 此使用户终端总是接收不到重要、 必须的 MCCH信息。
其中在 CELL— DCH状态下， WCDMA FDD终端在 UTRAN所指示的 压缩模式下进行异频测量， 其中压缩模式的技术原理如图 2 所示， 即 UTRAN在发送某些帧 （每 10ms发送的数据为一帧） 的时候， 加大数据 发送速率，用少于 10ms的时间发送完成原来需要在 10ms内发送的数据， 那么空余出来的时间就用于用户终端 UE进行异频测量，具体采用什么方 式和什么时间来加大发送速率， 则完全由 UTRAN进行控制。
WCDMAFDD终端处于 CELL— DCH状态下，接收 MBMS PTM业务 时， UTRAN通过下发承载有压缩模式的信息来控制用户终端进行异频测 量。 当用户终端支持在 MCCH上接收 MBMS控制信息时，不具有汉接收 机的用户终端进行异频测量时， 会中断对当前小区 MCCH信息的接收； 并且其执行异频测量的时间完全由 UTRAN发送的压缩模式信息来指示。
但是当 UTRAN构造用户终端异频测量的压缩模式时，根本没有考虑 MCCH信息的发射周期， 由于压缩模式信息是被用户终端重复应用的， 并且 MCCH信息也是周期性下发的 , 这样就会导致压缩模式所指示的异 频测量时间有可能总和 MCCH信息的下发时间重叠， 由此会导致用户终 端在 UTRAN指定的异频测量时间内进行异频测量时总是接收不到重要、 必须的 MCCH信息。
上述各种状态下的用户终端在进行异频测量时所存在的问题在进行 异系统测量时也同样存在。
发明内容 本发明要解决的技术问题在于提出一种多媒体广播组播业务中的异 频 /异系统测量方法及测量时间设置装置， 可以避免异频 /异系统测量时间 总和 UTRAN下发 MCCH信息的时间重叠，使得用户终端在异频 /异系统 测量期间能够接收 MCCH信息。

具体实施方式
本发明 MBMS 中的异频 /异系统测量方法针对现有技术中当用户终 端不具有双接收机时， 其异频 /异系统测量时间总是和 UTRAN 下发 MCCH信息的时间重叠， 致使用户终端在进行异频 /异系统测量时总是接 收不到重要、 必须的 MBMS消息的缺陷， 而提出当用户终端不具有双接 收机时，考虑用户终端所处不同状态，由用户终端判断、控制或由 UTRAN 调度用户终端控制异频 /异系统测量时间， 使得用户终端在进行异频 /异系 统测量的同时避免测量时间总是与 MCCH信息的下发时间重叠。
如图 3 所示为本发明的其一主要实现原理流程图， 其主要实现原理 如下：
步骤 S10, 用户终端 UE根据 UTRAN下发 MCCH信息的时间设置 避免与 MCCH信息下发时间总重叠的异频 /异系统测量时间；
步骤 S20 , UE在上述自身设置的异频 /异系统测量时间进行异频 /异系 统测量处理。
其中 UE可以在 UTRAN下发的系统信息中获知 UTRAN下发 MCCH 信息的时间， 因为 UTRAN下发的系统信息中包括 MCCH信息的调度信 息和异频 /异系统测量信息 ,其调度信息中又进而包括 MCCH信息的发射 时间、 MCCH信息下发过程中的修改周期、接入信息周期和重复周期等； 而异频 /异系统测量信息又进而包括触发异频 /异系统测量的各种信息。
如图 4所示为本发明的另一主要实现原理流程图， 其主要实现原理 如下：
步骤 S100， UTRAN根据自身下发 MCCH信息的时间设置避免与 MCCH信息下发时间总重叠的异频 /异系统测量时间；
步驟 S110， UTRAN将上述设置的异频 /异系统测量时间指定给 UE; 步骤 S120, UE在 UTRAN指定的异频 /异系统测量时间进行异频 /异 系统测量处理。
其中当用户终端处于 CELL— FACH状态下时， 由用户终端设置异频 / 异系统测量时间， 具体实现过程如图 5 所示， 该处理过程用于处在 CELL— FACH状态下的用户终端在支持 MBMS情况下的异频测量处理， 其主要实现过程为：
步驟 S31 , UE从 UTRAN下发的系统信息中获取 UTRAN下发 MCCH 信息的时间 （其中 UTRAN会向 UE下发 MCCH的调度信息， 该调度信 息包括 MCCH信息发射时间、 修改周期、 接入信息周期、 重复周期等）； 步驟 S32, ΌΈ触发异频 /异系统测量处理，并计算自身的异频 /异系统 测量时间， 其中根据如下公式计算自身的异频 /异系统测量时间：
SFN= ( C_RNTI mod M— REP + n x M_REP ) x N
用户终端在满足上述公式的帧 SFN中执行异频 /异系统测量； 其中 N是用户终端监控的承载非 MBMS业务逻辑信道的辅助公共控 制物理信道 ( SCCPCH, Secondary Common Control Physical Channel ) 上有最大发射时间间隔 TTI的前向接入信道 FACH的传输时间间隔 TTI 除以 10ms;
M_REP是测量间隔循环周期， M_REP = 2k,一个 N帧的测量时间的 重复周期是 N x M— REP帧； 其中 k是前向接入信道 FACH测量间隔循环 周期系数,在系统信息 11或 12所含的前向接入信道测量时刻信息 "FACH measurement occasion info" 中读取； C_RNTI是用户终端 UE的无线网络临时标识值；
n = 0, 1 , 2... , 只要 SFN低于其最大值。
步骤 S33 , UE在计算得到自身的异频 /异系统测量时间后， 比较自身 的异频 /异系统测量时间是否总和 UTRAN下发 MCCH信息的时间重叠， 如果是， 执行步骤 S34; 否则执行步骤 S35;
步骤 S34， UE将上述计算得到的异频 /异系统测量时间进行偏移， 得 到新的异频 /异系统测量时间； 这里假设偏移时间值为 Measurement Offset。 其中该偏移时间值 Measurement Offset可以由用户终端 UE随机 产生， 并且该偏移时间值 Measurement Offset大小为 UE在 CELL— FACH 状态下监控的承载非 MBMS业务逻辑信道的发射时间间隔 TTI最大的前 向接入信道 FACH的发射时间间隔 TTI内所含帧数的整数倍， 并保证新 的异频 /异系统测量时间不总和 MCCH信息的下发时间重叠。 播发送给用户终端 , 并且该偏移时间值 Measurement Offset大小为用户终 端在 CELL— FACH状态下监控的承载非 MBMS业务逻辑信道的发射时间 间隔 TTI最大的前向接入信道 FACH的发射时间间隔 TTI内所含帧数的 整数倍，并保证新的异频 /异系统测量时间不总和 MCCH信息的下发时间 重叠。经过偏移处理后的异频 /异系统测量时间应该满足下列公式的要求： SFN = (C_RNTI mod M— REP + n * M—REP) * N + Measurement Offset。
步驟 S35 , 用户终端 UE在 UTRAN下发 MCCH信息的时间接收 MCCH信息， 并在异频 /异系统测量时间进行异频 /异系统测量处理。
此外当用户终端处于 CELL— FACH状态下时， 还可以由 UTRAN设 置异频 /异系统测量时间， 具体实现过程如图 6所示， 该处理过程用于处 在 CELL— FACH状态下的用户终端在支持 MBMS 情况下的异频测量处 理， 其主要实现过程为：
