持续时间的确定方法及小区协作实体 技术领域 本发明涉及通信领域, 具体而言, 涉及一种持续时间的确定方法及小区协作实体 (Multi-cell/multicast Coordination Entity, 简称为 MCE)。 背景技术 随着互联网的迅猛发展和大屏幕多功能手机的普及, 出现了大量移动数据多媒体 业务和各种高带宽多媒体业务, 例如: 视频会议、 电视广播、 视频点播、 视频广告、 网上教育、 互动游戏等, 不仅满足了移动用户不断上升的业务需求, 同时也为移动运 营商带来新的业务增长点。 这些移动数据多媒体业务要求多个用户能够同时接收相同 数据, 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。 为了有效地利用移动网络资源, 第三代合作伙伴计划 (3rd Generation Partnership Project, 简称为 3GPP ) 提出了多媒体广播多播业务 (Multicast Broadcast Multicast Service, 简称为 MBMS), 该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业务不仅能够实现纯文本低速率的消息类组播 和广播, 还能够实现高速多媒体业务的广播和组播, 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,为第三代数字通信 (3rd Generation, 简称为 3G) 的发展提供了更好的业务前景。 在 LTE R10中为 MBMS业务引入了计数过程 (counting procedure), 计数的方式 是基站通过每个多播广播单频网络 (Multicast Broadcast Single Frequency Network, 简 称为 MBSFN)区域的 MCCH发送本区域内需要进行计数的计数请求(counting request) 信息给 UE, 该计数请求中包含本 MBSFN区域需要被计数的 MBMS业务的信息, 当 UE接收到该 message后,解析其中的 MBMS业务的信息,如果 UE正在接收这些 MBMS 业务或者是 UE感兴趣接收这些 MBMS业务, 那么 UE需要给网络侧发送一个响应的 消息, 称为计数响应消息 (counting response )。 基站的 counting request的消息中的被统计的 MBMS业务的信息是来自 MCE的, 并且 MCE进一步还需要向基站提供计数过程的结束时间。 以保证计数过程中 MBSFN 区域中所有相关基站能够及时把计数结果上报给 MCE, 以使得本次计数过程及时结 束, 以便于及时开启下一次计数过程。 在现有技术中, 计数是以 MBSFN区域为单位进行, 即每一个 MBSFN区域内的 需要被计数的 MBMS业务的信息通过本区域的 MCCH下发给 UE, UE反馈时需要携 带正在接收或者感兴趣接收那些 MBMS 业务的信息, 而且还要携带本区域的标识信 息。 在有多个 MBSFN 区域重叠覆盖的场景下, 如果每个区域内都有需要计数的 MBMS业务,那么 MCE可以同时配置多个 MBSFN区域的需要计数的 MBMS业务在 一个计数过程中,那么如果同时配置多个不同 MBSFN区域的需要计数的 MBMS业务 在一个计数过程中, 由于多个 MBSFN区域的 MCCH修改周期可能不同, 那么基站在 MCCH中发送 counting request的时间不同、 次数不同, UE接收到的 counting request 的时间不同, 反馈的时间也不相同, 从而导致 MBMS计数持续时间的不合理, 进而降 低所有相关基站计数过程的效率。 发明内容 本发明提供了一种持续时间的确定方法及小区协作实体, 以至少解决相关技术中 由于多个 MBSFN区域的 MCCH修改周期不同而导致 MBMS计数持续时间不合理的 问题。 为了实现上述目的, 根据本发明的一个方面, 提供了一种持续时间的确定方法。 根据本发明的持续时间的确定方法包括: MCE确定对 MBSFN区域的 MBMS业 务进行计数; MCE配置 MBMS业务处于同一个计数过程中; MCE根据 MBSFN区域 中的每个 MBSFN区域中的 MCCH的修改周期, 确定计数过程的持续时间。
MCE根据 MBSFN区域中的每个 MBSFN区域中的 MCCH的修改周期, 确定计 数过程的持续时间包括:当 MCE确定 MBSFN区域中的每个 MBSFN区域中的 MCCH 的修改周期中的至少一个 MCCH的修改周期与其余 MCCH的修改周期的大小不相同 时, MCE确定 MCCH的修改周期中的最长的修改周期作为计数过程的持续时间。
MCE根据 MBSFN区域中的每个 MBSFN区域中的 MCCH的修改周期, 确定计 数过程的持续时间还包括: MCE确定计数过程的持续时间为 10.24秒。
MCE根据 MBSFN区域中的每个 MBSFN区域中的 MCCH的修改周期, 确定计 数过程的持续时间包括:当 MCE确定 MBSFN区域中的每个 MBSFN区域中的 MCCH 的修改周期相同时, MCE确定 MCCH的修改周期作为计数过程的持续时间。 MCE根据 MBSFN区域中的每个 MBSFN区域中的 MCCH的修改周期, 确定计 数过程的持续时间还包括: 当 MCE确定 MBSFN 区域中的每个 MBSFN 区域中的 MCCH的修改周期均为 5.12秒时, MCE确定计数过程的持续时间为 10.24秒。 在 MCE根据 MBSFN区域中的每个 MBSFN区域中的 MCCH的修改周期, 确定 计数过程的持续时间之后, 上述方法还包括以下之一: MCE将计数过程的持续时间发 送给基站; MCE不发送计数过程的持续时间给基站, 基站通过标准协议固化的计数过 程持续时间的规则确定计数过程的持续时间。 在 MCE 向基站发送计数过程的持续时间之后, 上述方法还包括: 基站使用计数 过程的持续时间, 执行计数过程。 在 MCE 向基站发送计数过程的持续时间之后, 上述方法还包括: 基站根据计数 过程的持续时间, 并根据基站所属的 MBSFN区域, 确定计数过程的持续时间; 基站 使用计数过程的持续时间, 执行计数过程。 为了实现上述目的, 根据本发明的另一个方面, 提供了一种 MCE。 根据本发明的 MCE包括: 第一确定模块, 设置为确定对 MBSFN区域的 MBMS 业务进行计数; 配置模块, 设置为配置 MBMS业务处于同一个计数过程中; 第二确定 模块, 设置为根据 MBSFN区域中的每个 MBSFN区域中的 MCCH的修改周期, 确定 计数过程的持续时间。 第二确定模块包括:第一确定子模块,设置为确定 MBSFN区域中的每个 MBSFN 区域中的 MCCH的修改周期中的至少一个 MCCH的修改周期与其余 MCCH的修改周 期的大小不相同; 第二确定子模块, 设置为确定 MCCH的修改周期中的最长的修改周 期作为计数过程的持续时间。 第二确定模块包括:第三确定子模块,设置为确定 MBSFN区域中的每个 MBSFN 区域中的 MCCH的修改周期相同; 第四确定子模块, 设置为确定 MCCH的修改周期 作为计数过程的持续时间。 第二确定模块包括:第五确定子模块,设置为确定 MBSFN区域中的每个 MBSFN 区域中的 MCCH的修改周期均为 5.12秒; 第六确定子模块, 设置为确定计数过程的 持续时间为 10.24秒。 本发明通过 MCCH的修改周期与计数过程的持续时间相关联,解决了相关技术中 由于多个 MBSFN区域的 MCCH修改周期不同而导致 MBMS计数持续时间的不合理 的问题, 从而可以使得 UE调度上报更加合理, 进而降低所有相关基站计数过程的效 率。 附图说明 此处所说明的附图用来提供对本发明的进一步理解, 构成本申请的一部分, 本发 明的示意性实施例及其说明用于解释本发明, 并不构成对本发明的不当限定。 在附图 中: 图 1是根据本发明实施例的持续时间的确定方法的流程图; 图 2是根据本发明实施例的多个 MBSFN区域的 MCCH发送的示意图; 图

1所示, 包括如下的步骤 S102至步骤 S106。 步骤 S102, MCE确定对 MBSFN区域的 MBMS业务进行计数。 步骤 S 104, MCE配置 MBMS业务处于同一个计数过程中。 步骤 S106, MCE根据 MBSFN区域中的每个 MBSFN区域中的 MCCH的修改周 期, 确定计数过程的持续时间。 相关技术中, 由于 MBSFN区域的 MCCH修改周期不同, 从而导致 MBMS计数 持续时间的不合理。本发明实施例中, 通过 MCCH的修改周期与计数过程的持续时间 相关联, 可以使得 UE调度上报更加合理, 进而降低所有相关基站计数过程的效率。 优选地, MCE根据 MBSFN区域中的每个 MBSFN区域中的 MCCH的修改周期, 确定计数过程的持续时间包括:当 MCE确定 MBSFN区域中的每个 MBSFN区域中的 MCCH的修改周期中的至少一个 MCCH的修改周期与其余 MCCH的修改周期的大小 不相同时, MCE确定 MCCH的修改周期中的最长的修改周期作为计数过程的持续时 间。 优选地, MCE根据 MBSFN区域中的每个 MBSFN区域中的 MCCH的修改周期, 确定计数过程的持续时间还包括: MCE确定计数过程的持续时间为 10.24秒。 优选地, MCE根据 MBSFN区域中的每个 MBSFN区域中的 MCCH的修改周期, 确定计数过程的持续时间包括: MCE确定 MBSFN区域中的每个 MBSFN区域中的 MCCH的修改周期相同; MCE确定 MCCH的修改周期作为计数过程的持续时间。 优选地, MCE根据 MBSFN区域中的每个 MBSFN区域中的 MCCH的修改周期, 确定计数过程的持续时间还包括: MCE确定 MBSFN区域中的每个 MBSFN区域中的 MCCH的修改周期均为 5.12秒; MCE确定计数过程的持续时间为 10.24秒。 优选地, 在 MCE根据 MBSFN区域中的每个 MBSFN区域中的 MCCH的修改周 期, 确定计数过程的持续时间之后, 上述方法还包括以下之一: MCE将计数过程的持 续时间发送给基站; MCE不发送计数过程的持续时间给基站, 基站通过标准协议固化 的计数过程持续时间的规则确定计数过程的持续时间。 优选地, 在 MCE 向基站发送计数过程的持续时间之后, 上述方法还包括: 基站 使用计数过程的持续时间, 执行计数过程。 优选地, 在 MCE 向基站发送计数过程的持续时间之后, 上述方法还包括: 基站 根据计数过程的持续时间, 并根据基站所属的 MBSFN区域, 确定计数过程的持续时 间; 基站使用计数过程的持续时间, 执行计数过程。 下面将结合实例对本发明实施例的实现过程进行详细描述。 本发明的基本思想是当有多个不同的 MBSFN区域的 MBMS业务在一个计数过程 中时, 由于不同的 MBSFN区域的 MCCH的修改周期可能不相同, 根据本发明可以为 所述计数过程确定一个合理的计数持续时间, 以便于计数过程中所有相关基站及时参 与反馈, 使得计数过程的效率提高。 当一个计数过程中包含的 MBMS业务所在的多个不同的 MBSFN区域的 MCCH 修改周期不同时, 那么选择其中 MCCH修改周期最大取值为计数过程的持续时间。针 对 LTE系统, 也可以固定为 10.24s。 当一个计数过程中包含的 MBMS业务所在的多个不同的 MBSFN区域的 MCCH 修改周期相同时, 那么选择一个 MCCH修改周期的取值为计数过程的持续时间。针对 LTE系统, 当多个不同的 MBSFN区域的 MCCH修改周期为 5.12s时, 那么所述计数 过程为 5.12s, 即一个 MCCH修改周期, 如果当多个不同的 MBSFN区域的 MCCH修 改周期为 10.24s时, 所述计数过程为 10.24s, 也是一个 MCCH修改周期。 考虑到实现简单性, 针对 LTE系统, 当有多个不同的 MBSFN区域的 MBMS业 务在一个计数过程中时, 计数过程的持续时间选择所述多个不同 MBSFN 区域的 MCCH中 MCCH修改周期最大一个作为持续时间, 可以确定为一个 MCCH修改周期 或者两个 MCCH修改周期时长。 图 2是根据本发明实施例的多个 MBSFN区域的 MCCH发送的示意图,如图 2所 示, MBSFNl和 MBSFN3的 MCCH修改周期是相同的,且不同于 MBSFN2的 MCCH 修改周期。 图 3是根据本发明实施例的计数过程的交互流程图, 如图 3所示, 计数过程是指 MCE发起计数命令后, 直到接收所有基站最终反馈的计数结果为止, 包括如下的步骤 S302至步骤 S308。 步骤 S302, MCE发送 MBMS计数开始命令 (Counting Initiation) 给相关基站。 具体地,包含那些 MBMS业务需要被进行计数,这些业务可能来自不同的 MBSFN 区域, 并且这些不同的 MBSFN区域的 MCCH的修改周期也是不一样长的。这将会导 致 UE从 MCCH中接收的计数请求(Counting Request) 的时间点不同, 有一些 UE接 收的早一些, 有一些 UE接收的晚一些。 这样就会引起 UE给基站发送计数响应消息 (Counting Response) 的时间差异比较大, 这样不便于网络侧控制计数过程的持续时 间。 按照本发明给出的方法可以保证所有 UE不延误上报时间, 基站在整理 UE上报 的信息后, 不延误基站给 MCE上报。 步骤 S304, 基站发送 Counting Request给 UE。 具体地, 基站把接收到的 MBMS Counting Initiation中的需要计数的 MBMS业务 按照 MBSFN区域分组, 把同一 MBSFN区域的 MBMS业务分为一组, 把该组的需要 计数的 MBMS业务的信息通过该 MBSFN区域的 MCCH发送给 UE。基站需要在有计 数需要的每一个 MBSFN区域的 MCCH中发送包含该 MBSFN区域的 MBMS业务的 计数信息给 UE。 步骤 S306, UE发送 Counting Response给基站。 具体地, UE在接收到基站通过 MCCH发送的 Counting Request后, 解析其中包 含的 MBMS业务信息,如果 UE正在接收或者感兴趣接收 Counting Request中的 MBMS 业务, 那么 UE需要向网络侧发送 Counting Response, 报告自己正在接收的 MBMS业 务信息。 步骤 S308, 基站发送 MBMS计数报告 (Counting report) 给 MCE。 具体地, 基站把接收到来自的 UE反馈的信息进行整理后, 然后上报给 MCE。 根据本发明, 当 MBMS Counting Initiation中包含不同的 MBSFN区域的 MBMS 业务需要被计数时, MCE 确定本次计数过程的持续时间的方法为: 选择其中多个 MBSFN 区域中 MCCH 的修改周期最大的一个对应的数值为本次计数过程的持续时 间, 这个计数过程的持续时间可以通过参数配置后, 由 MCE发送给相关基站, 然后 基站再发送给 UE, 或者这个计数过程的持续时间采用约定为需要计数的多个不同 MBSFN区域中 MCCH修改周期最长的取值 (如果只有一个 MBSFN区域, 则选择该 MBSFN区域的 MCCH修改周期的取值), MCE不再发送计数持续时间给基站, 而是 采用标准协议把确定所述计数过程持续时间的规则固化为 MCE和基站均遵守的算法, 即基站默认使用计数的 MBMS所述的 MBSFN中 MCCH修改周期最大 MCCH修改周 期的取值。 即整个计数过程必须在这个计数过程的持续时间内完成, 这样, 当 MCE 把 MBMS Counting Initiation发送给相关基站时, 即根据计数过程的持续时间, 调度相 应的 Counting Request及时通过 MCCH发送给 UE, 并且把持续时间也可以通知给 UE (也可以不通知 UE, 那么规定 UE接收到 Counting Request后, 立即反馈即可), UE 则在持续时间的结束点之前(UE需要给基站预留一定的处理 UE上报信息的时间, 这 个时间由 UE控制)及时 Counting Response上报给基站,基站在接收到 UE的上报后, 进行整理后及时在计数持续时间内报告给 MCE, 从而结束本次计数过程。按照本发明 确定计数过程的持续时间后, 可以不用通知 UE关于计数过程的持续时间, 因为可以 通过标准协议把本发明确定计数持续时间的规则固化, 即本发明中 UE默认选择了自 己需要上报计数的 MBMS业务所在的 MBSFN区域中 MCCH修改周期最大的取值为 计数持续时间, 能够满足所有 UE的上报需求。 在一个计数过程中, 如果 UE同时在两个不同的 MBSFN区域正在接收 MBMS业 务, 如果这两个 MBSFN区域的 MCCH修改周期不同时, 并且 UE正在接收的 MBMS 业务都进行计数,那么 UE本次上报 Counting Response可以按照 MCCH修改周期较长 的对应的时间来确定上报时间, 从而为 UE获得了一个较长的上报时间窗, 可以使得 UE调度上报更加合理。 优选实施例一 本优选实施例一描述了 MCE配置计数过程的持续时间, 并发送给基站, 基站直 接使用配置持续时间。 假设 MCE配置一个计数过程,这个计数过程中包含 3个 MBSFN区域中需要被计 数的 MBMS业务, 此时 MCE确定这 3个 MBSFN区域的 MCCH的修改周期的大小, 选择其中 MCCH修改周期最大的取值为本次计数过程的持续时间。 然后 MCE把需要 计数的 MBMS业务发送给相关基站, 同时也可以把持续时间发送给相关基站(也可以 不发送持续时间,采用上述的默认方式)。此时由于基站所属的 MBSFN区域可能不同, 例如一些基站仅属于上述 3个 MBSFN区域中的某一个, 也可以基站同时属于上述 3 个 MBSFN区域中的某 2个, 那么此时基站不能识别自己不属于的 MBSFN区域的相 关信息,例如 MBMS业务信息, MBSFN区域标识信息,也不知道自己不属于的 MBSFN 区域的 MCCH修改周期大小。 但是此时 MCE把本次计数过程的持续时间已经配置下 来了,这个所有的基站都是识别的,那么基站就按照这个持续时间执行本次计数过程。 这里还需要说明, 基站对于自己不属于的 MBSFN的信息直接丢弃, 仅把 MCE发送 MBMS业务中自己识别的 MBMS业务按照自己所属的 MBSFN区域进行分组, 然后 把每一组在对应的 MBSFN区域的 MCCH中发送给 UE。 如图 2所示,假设有 3个 MBSFN区域,分别为 MBSFN1、 MBSFN2和 MBSFN3 , 其中每个 MBSFN区域的 MCCH的修改周期大小如图 2示意, 如果 MCE在一次计数 过程中配置了这 3个 MBSFN区域的 MBMS业务, 那么 MCE应该配置本次计数过程 的持续时间为 MBSFN2的 MCCH修改周期的大小, 因为 MBSFN2的修改周期最大, 并把持续时间发送给基站。 优选实施例二 本优选实施例二描述了 MCE配置计数过程的持续时间, 并发送给基站, 基站再 根据自己的情况确定适合自己的计数过程持续时间。 假设 MCE配置一个计数过程,这个计数过程中包含 3个 MBSFN区域中需要被计 数的 MBMS业务, 此时 MCE确定这 3个 MBSFN区域的 MCCH的修改周期的大小, 选择其中 MCCH修改周期最大的取值为本次计数过程的持续时间。 然后 MCE把需要 计数的 MBMS业务发送给相关基站, 同时也可以把持续时间发送给相关基站。此时由 于基站所属的 MBSFN区域可能不同, 例如一些基站仅属于上述 3个 MBSFN区域中 的某一个, 也可以基站同时属于上述 3个 MBSFN区域中的某 2个, 那么此时基站不 能识别自己不属于的 MBSFN区域的相关信息, 例如 MBMS业务信息, MBSFN区域 标识信息, 也不知道自己不属于的 MBSFN区域的 MCCH修改周期大小。 但是此时 MCE把本次计数过程的持续时间已经配置下来了, 这个所有的基站都是识别的, 但是 基站需要进一步参考自己所属的 MBSFN区域的 MCCH修改周期大小, 例如图 2中, 某一基站接收到 MCE发送的计数持续时间为 MBSFN2的 MCCH修改周期的大小,但 是该基站仅属于图 1中的 MBSFN1区域覆盖, 那么此时, 该基站可以把本次计数过程 的持续时间再一次确定为 MBSFN1的 MCCH的修改周期的大小。 如果基站同时属于 MBSFN1和 MBSFN2区域, 那么基站选择其中 MCCH修改周期较大的一个再次确定 为该基站的本次计数过程的持续时间。 但是这个新确定的持续时间不能大于 MCE配 置的持续时间。 如果基站再次确定持续时间大于 MCE配置的持续时间, 那么基站采 用 MCE配置的持续时间。这里还需要说明,基站对于自己不属于的 MBSFN的信息直 接丢弃,仅把 MCE发送 MBMS业务中自己识别的 MBMS业务按照自己所属的 MBSFN 区域进行分组, 然后把每一组在对应的 MBSFN区域的 MCCH中发送给 UE。 如图 2所示,假设有 3个 MBSFN区域,分别为 MBSFN1、 MBSFN2和 MBSFN3 , 其中每个 MBSFN区域的 MCCH的修改周期大小如图 2示意, 如果 MCE在一次计数 过程中配置了这 3个 MBSFN区域的 MBMS业务, 那么 MCE应该配置本次计数过程 的持续时间为 MBSFN2的 MCCH修改周期的大小, 因为 MBSFN2的修改周期最大, 并把持续时间发送给基站。 优选实施例三 本优选实施例三描述了采用默认的或者是预先设定的方式配置持续时间, 基站再 根据自己的情况确定适合自己的计数过程持续时间。 假设 MCE配置一个计数过程,这个计数过程中包含 3个 MBSFN区域中需要被计 数的 MBMS业务, 此时 MCE确定这 3个 MBSFN区域的 MCCH的修改周期的大小, 默认其中 MCCH修改周期最大的取值为本次计数过程的持续时间,此时不需要发送信 令通知基站关于持续时间的大小。 然后 MCE把需要计数的 MBMS业务发送给相关基 站。 此时基站需要再一次确定适合持续时间, 此时基站把自己所属的 MBSFN区域中 MCCH 修改周期最大的取值再次确定为基站的持续时间。 基站把需要计数的 MBMS 按照各自的 MBSFN区域分组, 分别在各自 MBSFN区域发送给 UE, UE默认反馈时 间为自己需要反馈计数信息的 MBMS业务所述的 MBSFN的 MCCH的修改周期的大 小作为计数反馈结束点。 如果 UE需要反馈计数信息的 MBMS业务属于多个 MBSFN 区域, 那么 UE选择所述多个 MBSFN区域中最大的 MCCH修改周期的取值为计数反 馈结束点。 例如图 2中, MCE默认方式配置持续时间, 那么按照默认约定, MCE选择这 3 个 MBSFN 区域中 MCCH 修改周期最大的一个作为持续时间, 本实施例中应该为 MBSFN2的 MCCH的修改周期大小, 但是某一基站仅属于图 2中的 MBSFN1区域覆 盖, 那么此时, 该基站可以把本次计数过程的持续时间再一次确定为 MBSFN1 的 MCCH的修改周期大小, 因为该基站并不知道有 MBSFN2存在, 那仅属于 MBSFN1 区域, 仅知道 MBSFN1区域的 MCCH修改周期的大小。 如果基站同时属于 MBSFN1 和 MBSFN2区域, 那么基站选择其中 MCCH修改周期较大的一个再次确定为该基站 的的本次计数过程的持续时间。 这里还需要说明, 基站对于自己不属于的 MBSFN的 信息直接丢弃, 仅把 MCE发送 MBMS业务中自己识别的 MBMS业务按照自己所属 的 MBSFN区域进行分组, 然后把每一组在对应的 MBSFN区域的 MCCH中发送给
