Description

多媒体广播组播业务计数方法及系统 技术领域
本发明涉及多媒体广播组播业务统计技术, 尤其涉及一种多媒体广播 组播业务计数方法及系统。 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。 这些移动数据多媒体业务和 各种高带宽多媒体业务, 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了新的业务增长点。 这些移动数据多媒体业务和各种 高带宽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 (3GPP , 3rd Generation Partnership Project ) 提出了多媒体广播多播业务 ( MBMS , Multimedia Broadcast Multicast Service ), 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业务不仅能够实现纯文本低速率的消息类的组播和广播, 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( 3G, 3rd Generation ) 数字通信的发展提供了更好的业务前景。
目前, 在长期演进( LTE, Long Term Evolution )版本 9 ( R9 ) 系统中 引入了 MBMS业务, 并在 LTE版本 10 ( R10 ) 中进行了优化。 MBMS业 务在系统中承载需要控制信令(也称为 MBMS控制信令)和用户数据(也 称为 MBMS业务)的共同传输来进行实现。 其中, 控制信令将会告知接收 端(如终端、 用户设备(UE, User Equipment ) )相应的控制参数, 指引 UE 到相应的位置去接收其感兴趣的 MBMS 业务(即相应的用户数据)。 这种 MBMS控制信令(控制信息, 包括: MBMS业务的配置信息等 )在 LTE系 统中是通过多播控制信道(MCCH, Multicast Control Channel )来进行传输 的, MBMS业务是通过多播业务信道 ( MTCH, Multicast Traffic Channel ) 来进行传输的。
具体说来, 在逻辑信道 MCCH上传输的 MBMS控制信令(即 MCCH 信息 )主要包含: MCCH信息所对应的多播单频网络( MBSFN, MBMS over a Single Frequency Network )区域的多播资源, 该 MBSFN 区域中所有正在 发送的 (ongoing ) MBMS业务(或称之为已经开始的 MBMS业务, 或称 之为已经 session start的 MBMS业务), 以及 ongoing MBMS业务的配置和 属性信息; 在逻辑信道 MTCH承载的是 MBMS业务数据, 一般将 MBMS 业务与 MTCH进行对应, 例如, MBMS业务 1与 MTCH1对应, MBMS业 务 2与 MTCH2对应 , 也就是说, UE读取 MBMS业务与 UE读取 MTCH 表达的是相同的含义。在网络中, MBMS业务使用临时移动组标识(TMGI, Temporary Mobile Group Identity )进行唯一地标识, 每个 MBMS业务都有 其相应的 TMGI, 便于网络侧和 UE进行识别。
其中, MBSFN area所对应的 MCCH信息将会按照一定的规律(重复 周期、 修改周期)进行发送, 具体如图 1所示。 图 1为现有技术中 MBSFN area的 MCCH信息发送示意图, 如图 1所示, MCCH信息在修改周期内将 会重复发送一次或多次(图 1中重复发送了 3次); MCCH信息重复发送之 间的时间间隔称之为 MCCH重复周期; 一般将 MCCH修改周期内, MCCH 信息的第一次发送称为首次发送, 每个重复周期的发送称为 MCCH信息重 复发送, 重复发送的 MCCH信息与首次发送的 MCCH信息内容完全相同; MCCH修改周期即表明在不同的 MCCH修改周期内, 所发送 MCCH信息 的内容可以不相同; 如图 1中 MCCH修改周期 n+1周期的内容与 n周期的 内容不相同 (图 1 中用斜线方块和空白方块表示了 MCCH信息的不同内 容); 需要注意的是, 在 MCCH修改周期内, MCCH信息的内容是不能发 生变更的, 仅能遵循重复周期进行重复发送。 MCCH信息的内容仅允许在 MCCH修改周期开始的边界处发生变更; 也就是说, MCCH信息的变更, 只能发生在 MCCH修改周期内第一次发送 MCCH信息时, 也称为 MCCH 改变时刻( MCCH change time )。这样的规定,保证了 MCCH信息在 MBSFN area内 (多 eNB )发送的一致性。
MCCH重复周期和修改周期的配置参数都是由网络侧进行配置的, 网 路侧通过 BCCH中的系统信息块 13 ( SIB13, System Information Blockl3 ) 发送给 UE; UE通过读取 BCCH中的 SIB13可以获知 MCCH重复周期和修 改周期的配置参数, UE可以在相应的位置上读取 MCCH信息。
考虑到现有技术中, 在 MBSFN Area中发送控制信令和用户数据将以 小区或 eNB为单位使用 MBSFN技术进行同步发送(目的是使得 UE在接 收时可以获得相应的合并增益), MBSFN技术需要 MBSFN area内各个小 区在相同的时频资源上发送相同的数据内容, 这样就需要对各个小区的资 源进行统一的调度和规划。 目前使用多小区 /多播协调实体 (MCE , Multi-cell/multicast Coordination Entity ) 网元来进行无线资源的统一调度和 规划, 具体可参考国际标准 3GPP 36.300 v910。
图 2为现有技术中长期演进( LTE, Long Term Evolution )系统的 MBMS 架构图, 如图 2所示, 在现有 LTE系统中, 与 MBMS相关的网元有 eNB、 MCE, MBMS网关( MBMS Gateway )、广播组播业务中心( BM-SC, Broadcast Multicast Service Centre )以及移动性管理单元 ( MME, Mobility Management Entity ), 其中, BM-SC作为业务发起 ( Session Start ), 业务停止(Session Stop )、业务更新 ( Session Updated )或 MBMS业务数据提供的网元; MBMS GW将 MBMS业务数据通过 Ml接口发送给相应的 eNB; MBMS GW通过 Sm接口将由 BM-SC生成的控制面信息(例如 Session Start Request message, Session Stop Request message, Session Updated Request message )发送给 MME; MME完全作为一个转发网元, 将 MBMS GW发送的控制面信息通 过 M3接口转发给 MCE; MCE将相应的控制面信息通过 M2接口发送给相 应的 eNB; 通过这样的处理, eNB将会获得 MBMS业务数据和相应的控制 面信息。 一般来说, MCE通过 M2接口发送给 eNB的控制面信息包括: 会 话开始请求消息( Session Start Request message )、会话停止请求消息( Session Stop Request message ) , 会话更新请求消息 ( Session Updated Request message )、 MBMS 调度消息 ( MBMS SCHEDULING INFORMATION message ), 复位消息 (Rest message ) , M2 建立请求消息 ( M2 SETUP REQUEST message ) , 以及通过 M2接口 eNB发送给 MCE相应的消息 , 例 如: 会话开始响应消息 ( Session Start Response message )、 会话停止响应消 息 ( Session Stop Response message )、 会话更新响应消息 ( Session Updated Response message )、 MBMS 调度响应消息 ( MBMS SCHEDULING INFORMATION Response message )、复位确认消息( Rest ACKNOWLEDGE message ), M2接口建立响应消息 ( M2 SETUP Response message )。 上述 MCE与 eNB之间的信令或过程承载在 M2接口上, 称为 M2应用协议, 即 M2 Application Protocol ( M2AP )。
通过上述的内容可以看出, MBMS业务将会在整个 MBSFN区域中进 行发送。为了进一步优化 MBMS业务发送,业界引入了 UE上行反馈机制, 具体而言, 上行反馈机制主要应用于网络侧获取每个 MBMS业务的感兴趣 /正在接收的用户数(或 UE个数); 网络侧通过获取用户数来优化 MBMS 业务的发送, 例如: 去激活 (deactivation, 或称之为不发送)感兴趣 /正在 接收用户数少的 MBMS 业务、 激活 (activation, 或称之为发送)感兴趣 / 正在接收用户数多的 MBMS 业务。 网络侧为了获知感兴趣 /正在接收某个 MBMS业务的 UE数量(或有 /无 ),可以通过发送 counting命令(计数命令), 使得感兴趣 /正在接收该 MBMS业务的 UE进行上行反馈, 告知该 UE目前 接收 MBMS的状态。 网络侧可以将通过上行反馈获取到的信息(即对于某 个 MBMS有多少感兴趣 /正在接收的 UE个数),应用于该 MBMS业务的激 活(activation )或去激活(deactivation )操作; 换言之, 网络侧可以根据上 行反馈获取到的信息来决定该 MBMS 业务在空口上是 ( activation ) 否 ( deactivation )进行发送 <>
但是, UE在空口上( UE至 eNB )将其感兴趣 /正在接收的 MBMS业 务报告给 eNB后,网络侧如何根据接收到的报告信息对 MBMS业务进行激 活 /去激活控制, 在现有技术中并没有给出可实现的方法。 发明内容
有鉴于此, 本发明的主要目的在于提供一种多媒体广播组播业务计数 方法及系统, 能及时准确地统计出当前 MBMS业务的接收 UE的状况。
为达到上述目的, 本发明的技术方案是这样实现的:

为使本发明的目的、 技术方案和优点更加清楚明白, 以下举实施例并 参照附图, 对本发明进一步详细说明。
首先, 网络侧(本发明中主要是指 MCE与 eNB )在 M2接口上, 触发 一个用于启动 counting的过程, 即 M2 MBMS Counting Initiation Procedure ( M2 接口上的 counting 启动过程, 也可以称为 MBMS counting start procedure ), 用于配置一个或多个 counting过程。
为了节省 M2接口上的信令开销,启动 counting的过程中可以包括若干 个相同或不相同的 counting过程, 每个 counting过程可以包括以下信息的 一个或多个: 业务列表(即用于计数的 MBMS的业务列表, 主要是 MBMS 的标识信息), 开始时间 (start time ), 持续时间 ( duration time ), 间隔时间 ( interval time )和重复次数 ( repetition number )。 当一个 counting过程的重 复次数大于 1时, 相当于该 M2 MBMS Counting Initiation Procedure要求该 counting过程执行多次, 也相当于配置了多个相同的 counting过程。
在每个 counting过程中, 需要包括 3个步驟, 即: 步驟 1 : eNB需要向 该 eNB控制下小区配置上述 MBMS业务的 counting指示信息; 步驟 2: UE 也需要从该 counting过程所配置的上述业务列表中选择 UE感兴趣或正在接 收的 MBMS业务并上报给 eNB; 步驟 3: eNB随后统计上述业务列表中每 个业务感兴趣或正在接收的 UE 个数并上报给 MCE。 也就是说, 一个 counting过程包括一次步驟 1 , 一次步驟 2和一次步驟 3。 步驟 1和步驟 2对应 Uu MBMS Counting过程(空口 MBMS Counting 过程)。 步驟 3对应 M2 MBMS Counting Report过程( M2接口的 Counting 结果的上 4艮过程)。 也就是说, 每个 counting 过程包括一个 Uu MBMS counting过程和 M2 MBMS Counting Report过程。
其中, 由于每个 counting过程很可能持续较长时间,或者一个 M2接口 上的 counting启动过程可能包括多个相同的 counting过程(如重复次数为 5 次等), MCE很可能在 counting期间更新或取消 counting过程。 如网络侧 通过当前的 counting 过程, 已经判定出是否需要激活 /去激活一个或多个 MBMS业务时, MCE将更新或取消随后的 counting过程。 本发明将通过下 文中的 M2 MBMS Counting Update过程( M2接口上的 MBMS Counting更 新过程)和 M2 MBMS Counting Sto 过程( M2接口上的 MBMS Counting 停止过程 )进行详细描述。 当然 , MCE也可以重新触发 M2 MBMS Counting Initiation过程来实现若干 MBMS业务的 counting的更新或取消。
实施例一
图 3为本发明中 M2接口上 MBMS counting启动流程图,如图 3所示,
M2 MBMS Counting Initiation Procedure ( M2接口上的 counting启动过程 ) 具体包括以下步驟:
步驟 301 , MCE向 eNB发送包括 MBMS counting initiation信息的消息。 本步驟中, MBMS counting initiation信息可以配置在新设置的新消息 中, 即为实现本发明技术方案, 新设置用于在 MCE及基站之间的用于启动 MBMS 计数的过程而设置相应的新消息, 如 MBMS Counting Initiation Request消息, 专门用于通知基站用于启动 MBMS的计数过程。 当然, 上 述的 MBMS counting initiation 信息也可以配置于已有的消息如 MBMS Scheduling Information消息中。 也就是说, 只要将 MBMS counting initiation 信息承载于相应的消息中而发送给基站即可, 本发明并不限定消息的格式 及类型。无论是新消息还是已有的消息都必须承载在 M2接口上。本发明中 的 MBMS counting initiation信息的内容如表 1所示:
Figure imgf000013_0001
表 1
其中, Counting procedure list ( counting 过程的个数): 在 MBMS counting initiation 信息中可以包括多个不同的 counting 过程 ( 1 , … maxCounting Number )0 一般地, 也可以总是配置一个 counting过程, 此时 该 MBMS counting initiation信息中不包括信息单元 Counting procedure list。
开始时间( start time ),也可以称为触发时间或 MCCH更新时刻( MCCH Update Time ); 它指明了 eNB在何时将一个或多个 counting过程中的若干 业务的 counting指示信息配置在 MCCH信息上。 可以采用下述任一方式: 方式 1 : 不配置而采用默认配置; 即: MBMS Counting Initiation信息中 不包括信息单元 "start time" , 也就是说, eNB收到来自 MCE的 counting 请求(例如: MBMS Counting Initiation request消息)后总是在下一个(或 默认的第几个 ) MCCH修改周期的 MCCH更新时刻将 counting指示配置在 MCCH上;
方式 2: 由 MCE为每个 counting过程都配置为一个绝对时间; 即: eNB 在随后的某个 MCCH MP将某个 counting 过程的 counting 指示配置在 MCCH 上, 不同的 counting 过程的开始时间可以相同或者不同, 但一个 counting过程中的所有业务的开始时间是相同的。
方式 3: 由 MCE为所有 counting过程都配置为一个绝对时间。 即: 在 MBMS Counting Initiation 信息中仅配置一个开始时间, 并用于 MBMS Counting Initiation信息中的所有 counting过程, 或者说 MBMS Counting Initiation信息中的所有 counting过程被配置相同的开始时间。
持续时间( duration time ); 它指明了 MCE请求 eNB针对一个 counting 过程中的若干个业务所需要计数(counting )的持续时间长度, 即, 从 eNB 开始某个 /某些业务的开始 counting到结束 counting的时间段,在空口上( Uu 接口, eNB与 UE之间的接口)表现为 eNB从在 MCCH信息上配置某个 / 某些业务的 counting指示到在 MCCH信息上删除该 /某些业务的 counting指 示的时间长度, 总之, 持续时间是指一个前述 counting过程中步驟 1的时 间长度(即: MCCH上始终配置业务列表的时间), 而不包括前述 counting 过程中步驟 2和步驟 3的时间长度。
MBMS counting initiation信息中所包含的不同 counting过程(例如针对 不同 MBMS的 counting过程 )所对应的持续时间可以相同也可以不同, 但 一个 counting过程的所有业务持续时间必须相同。 可以采用下述任一方式 进行表示:
方式 1 : 不配置; 此时 MBMS Counting Initiation信息中不包括信息单 元 "持续时间"; 例如, 所有的 counting过程所对应的持续时间总是持续几 个 MCCH MP的长度(例如, 固定为 N个 MCCH MP );
方式 2: 由 MCE为每个 counting过程都配置为一个持续时间; 例如 , 一个 counting过程的持续时间配置为持续几个 MCCH MP长度;
方式 3: 由 MCE为所有 counting过程仅配置一个持续时间, 并用于 MBMS Counting Initiation 信息中的所有 counting 过程, 或者, MBMS Counting Initiation信息中的所有 counting过程的所有业务被配置相同数目 的持续时间。 重复次数( Repetition number )也称为 Counting个数 ( counting number ), 它指明了一次 M2 MBMS Counting Initiation Procedure 中包括相同的 counting过程的个数。 间隔时间 (interval time ); 它指明了当 MCE为 eNB配置多个相同的 counting过程时 (即重复次数为多次时), 从上一个 counting过程的步骤 1 结束到下一个 counting过程的步骤 1开始之间的时间间隔。 间隔时间可以 采用下述任一方式进行表示:
方式 1: 为每个 counting过程都依次配置一个间隔时间; 方式 2: 为所有的 counting过程配置一个间隔时间, 也就是说 MBMS Counting Initiation信息中的所有 counting过程统一地配置一个间隔时间; 方式 3:不配置而采用默认配置, 此时 MBMS Counting Initiation信息不 包括该参数。 比如说: 间隔时间总是 0, 即每个 counting过程连续地配置和 进行, 或每个 counting过程间隔一个固定的时间长度。
需要说明的是,当一个 counting过程被配置了重复多次且间隔时间为 0 时, 下个 counting过程不必等到上一个 counting过程完成再执行, 而是在 上一个 counting过程的步驟 1完成后就可以开始下一个 counting过程的步 驟 1 ,也就是说下一个 counting过程开始执行时上一个 counting过程的步驟 2或步驟 3未必完成。 maxCounting Number 为最多 counting 过程数目, 当一个 counting initiation 过程中只能配置一个 counting 过程时, 则不需要该信息单元。 maxnoofServiceforcounting为每个 counting过程中的最多 MBMS业务数目 , 也就是 eNB配置在 MCCH上的业务列表。
步驟 302 , eNB 向 MCE 发送包含 MBMS counting initiation response/failure信息的消息。
如果 eNB可以实现包含 MBMS counting initiation信息的请求消息(如 MBMS Counting Initiation Request 消息), 则向 MCE发送包括 MBMS counting initiation response的确认消息; 如果 eNB未能实现请求消息, 则向 MCE发送包含 MBMS counting initiation failure的失败消息。 进一步地, MBMS counting initiation response/failure信息既可以配置在新的响应消息 (如图 3所示的 MBMS Counting Initiation Response/Failure消息), 也可以 配置在已有的响应消息中。
MCE如果没有接收到 eNB 的确认消息, 需要重新向 eNB 发送启动 counting的请求消息, 直到 eNB答复确认消息。
实施例二
图 4为本发明中 Uu接口的 counting结果上报流程图, 如图 4所示, Uu MBMS Counting过程(空口的 MBMS Counting过程 )具体包括以下步 驟:
步驟 401 , eNB通过空口发送 counting指示信息(对应 counting过程的 步驟 1 )。
eNB接收到 MCE的启动 counting消息并向 MCE反馈确认后 (即完成 了 M2 MBMS Counting Initiation过程后), eNB通过空口发送 counting指示 信息(如图 4所示, 该 counting指示信息承载于 Counting Request消息中), 以要求 UE向 eNB反馈其所感兴趣或正在接收的 MBMS业务。
Uu MBMS Counting过程是指上文中 counting过程的步驟 1和步驟 2, 而不包括步驟 3。 该 counting指示信息承载在点到多点控制信道上, 点到多点控制信道 可以是 MCCH或 BCCH; 每个 MBMS业务采用 TMGI来表示。 针对接收 到的每个 counting过程, eNB在其要求的开始时间、 持续时间、 间隔时间、 重复次数(即 counting个数;), 在 MCCH上配置一个或多个 MBMS业务的 counting指示信息, 上述 MBMS业务由 MCE通过 MBMS counting请求发 送到 eNB。
举例来说 ,根据 MCE配置的该 counting过程的开始时间 , eNB在 MCCH 改变时刻, 在 MCCH上配置一个业务列表 (即 counting指示信息), 并一 直持续 "duration time" 时间长度。
eNB在一个 counting过程的持续时间到达后 , 在 MCCH更新时间删除 该 counting过程的所有业务的 counting指示, UE读取 MCCH时也不会读 取到这些业务的 counting指示并也不再响应 counting 0
步驟 402, UE读取 MCCH获取需要 counting指示的 TMGI列表,并向 eNB反馈其感兴趣或正在接收的 MBMS业务(对应 counting过程的步驟 2 )。
具体地, 在一个 counting过程中, MCCH上配置的业务列表将持续地 出现 "duration time" , UE一旦读取 MCCH获取到该业务列表后, 将反馈其 感兴趣或正在接收的 MBMS业务。
实施例三
图 5为本发明中 M2接口的 counting结果上报流程图, 如图 5所示, M2 MBMS Counting Report过程( M2接口的 counting结果上 4艮过程, 对应 于 counting过程的步驟 3 )具体包括以下步驟:
步驟 501 , eNB向 MCE发送包括 MBMS counting report信息的消息 ( MBMS Counting Report消息);
eNB在完成 Uu MBMS Counting过程后,向 MCE上报业务的统计结果。 MCE如果正确地收到统计结果, 则向 eNB发送确认消息, 否则发送失败消
MBMS counting report 信息包括一个 counting 过程的所有业务的 counting统计结果,该信息既可以 载于一个新消息中也可以^载于一个已 有的消息中。 counting结果可以是以下方式的一种:
方式 1 : 感兴趣或正在接收的 UE个数(例如: 业务 1的用户数、 业务 2的用户数 业务 N的用户数);
方式 2: 在上述方式 1的基础上限定 UE个数最大取值, 即当用户数大 于最大取值时使用最大值上报 (该方法的好处是便于约定上报开销, 当 UE 个数到达最大值时, 上报更多的用户数的意义也就不大了);
方式 3: 感兴趣或正在接收的 UE个数的大致分类, 例如用户数少, 用 户数一般, 用户数多, 该 counting结果虽然比较粗糙, 但比较简单, 上报 开销小。
步骤 502, MCE向 eNB发送包括 MBMS counting report response/failure 信息的消息 ( MBMS Counting Report Response/Failure消息)。
MBMS counting report response/failure信息既可以承载于一个新消息中 也可以 载于一个已有的消息中。 具体的, 如果 MCE正确地接收到包括 MBMS counting report信息的消息,则 MCE向 eNB反馈包含 MBMS counting report response信息的确认消息 ,否则反馈包含 MBMS counting report failure 的失败消息。
实施例四
图 6为本发明中 M2接口的 counting的更新流程图, 如图 6所示, M2 MBMS Counting Update过程 ( M2接口的 counting更新过程) 可以更新某 个 /某些 counting过程, 还可以增加或删除若干个 counting过程中的业务列 表、 开始时间、 持续时间、 重复次数, 间隔时间等; 另外, 增加或删除若 干个 counting 过程, 可以通过再次触发 M2 MBMS Counting Initiation Procedure, 或 M2 MBMS counting sto 过程来实现。
具体包括以下步驟:
步驟 601 , MCE向 eNB发送 MBMS counting update信息的相关消息; 该更新 counting 的信息既可以承载于一个新消息中也可以承载于一个 已有的消息 (如 MBMS counting update消息 ) 中。 在该更新 counting的信 息中, MCE可能更新需要某个 /某些 counting过程, 即, 增加或删除若干个 counting过程, 或者修改若干个 counting过程的配置信息, 如某个或某些 counting过程的业务列表、 开始时间、 持续时间、 重复次数, 间隔时间等。
比如, 对于某个 counting过程, 可以增加或减少其中的业务, 或者修 改其中的时间参数等。
步驟 602, eNB向 MCE发送 MBMS counting update response信息的相 关消息。
如果 eNB正确地接收到 counting update请求并可以执行后, 向 MCE 发送 counting update确认; 如果 eNB不 正确地接 4史 ill counting update if 求后,向 MCE发送 MBMS counting update失败。同样地,该 counting update 确认 /失败信息既可以作为一个信息块配置于新的响应消息中也可以配置与 已有的响应消息中。 具体地, counting update 信息请求配置于新消息如 MBMS counting update消息或 MBMS counting update response/acknowledge 消息中, 并向 MCE发送 MBMS counting update Failure消息。
该过程与实施例一中的 M2 MBMS counting initiation过程非常相似。也 就是说, MCE也可以采用再次触发 M2 MBMS counting initiation过程, 重 新配置 counting过程。 实施例五
在一个 counting initiation过程中, MCE也可以取消 (也就是停止)若 干个 counting 过程。一旦某个 /某些 counting过程被删除,则该 /这些 counting 过程中的所有业务不再需要 counting了。图 7为本发明中 M2接口的 counting 的停止流程图, 如图 7所示, M2 MBMS counting sto 过程(M2接口的 counting的停止过程)具体包括以下步驟:
步驟 701 , MCE向 eNB发送包括 M2 MBMS counting sto 信息的消息; 该用于结束一个或多个 counting过程的信息既可以承载于一个新消息 中也可以 载于一个已有的消息中。 MCE可以在一个 counting过程内, 也 在第若干个相同的 counting过程之间, 即: 一个或多个相同 counting过程 中的任何时间, 向 eNB发送 counting停止命令。
步驟 702, eNB向 MCE发送包括 M2 MBMS counting stop response ( acknowledge ) /Failure信息的消息。
该 MBMS counting stop response ( acknowledge ) /Failure信息既可以承 载于一个新消息中也可以^载于一个已有的消息中。 如果 eNB可以正确地 接收则向 MCE响应确认消息, 否则响应失败消息。 此时, eNB将在 MCCH MP的开始在 MCCH上删除上述业务的 counting指示, 并不再统计上述业 务的 counting结果, 也不发送统计结果给 MCE。
实施例六
下面举例一个完整的 counting过程进一步阐明本发明技术方案的实质, 该 counting过程包括 MCE启动 counting, 然后到 eNB在 MCCH上配置 counting的业务歹 'J表, 最后到 counting过程的完成。
具体的, 包括以下步驟:
步驟 a, MCE向 eNB发送 MBMS counting initiation消息; 当网络侧需要统计一个或多个业务有多少个 UE对其感兴趣或正在接 收(对于没有开始的业务统计有多少 UE正在接收,对于没有开始的业务统 计有多少 UE感兴趣 )时, MCE向 eNB发送启动 counting的消息。 消息中 可以包括一个或多个 counting过程, 每个 counting过程包括: 一个业务列 表, 开始时间、 持续时间、 间隔时间、 重复次数等。
步骤 b, eNB向 MCE发送 MBMS counting initiation response消息; 如果 eNB可以正确地接收到 counting启动消息则反馈响应消息, 否则 反馈失败消息。
当 eNB向 MCE反馈失败消息, 则 MCE需要重新向 eNB发送 MBMS counting initiation消息直到 eNB可以正确地接收到并反馈成功消息。
步驟 c, eNB开始向其控制下的所有小区,在 MCCH上配置需要 counting 的业务列表;
在指定的开始时间, eNB在 MCCH上配置 counting的业务列表, 并一 直存在到持续时间, 每个 counting过程都有一个标识符(如: 序列号), UE 可以根据此标识符反馈本次 counting过程中其感兴趣或正在接收的业务。
步驟 d, eNB向 MCE发送 MBMS counting report消息;
在一个 counting过程完成后, eNB将向 MCE上报该 counting过程的统 计结果;
步骤 e, MCE向 eNB发送 MBMS counting report acknowledge消息 如果 MCE可以正确地接收到报告消息则反馈响应消息,否则反馈失败 消息。
当 eNB向 MCE反馈失败消息,则 eNB需要重新向 MCE发送 counting 报告消息直到 MCE可以正确地接收到并反馈成功消息。
当 MCE通过 MBMS counting initiation过程为一个 counting过程配置了 多次,并且,对于该 counting过程的所有业务,如果 MCE根据本次 counting 报告(也可以是其他因素) 而决定不再需要后续的 counting过程(即不需 要计数该 counting过程中的所有业务, 当然该 counting过程中的业务列表 可以是仅有一个业务), 则 MCE向 eNB发送 MBMS counting sto 消息; 该 MBMS counting sto 消息用于删除一个或多个 counting过程。 eNB向 MCE 发送 MBMS counting stop acknowledge消息, 并在 MCCH上不再配置该 counting 过程, 即 MCCH 上不再包括该 counting 过程中的所有业务的 counting指示。
或者对于该 counting过程中的若干业务, 如果 MCE根据本次 counting 报告(也可以是其他因素)而决定不再需要后续的这些业务,则 MCE向 eNB 发送 MBMS counting update消息; 该消息可以删除一个 counting过程中的 若干业务(相当于调整该 counting过程的业务列表), 另外还可以重新配置 一个 counting过程中的其它配置参数(如: 开始时间、 持续时间, 间隔时 间, 重复次数等)。
eNB向 MCE发送 MBMS counting update acknowledge消息; eNB向
MCE答复确认消息,并在 MCCH上不再配置该 counting过程中的若干业务, 即 MCCH上不再包括该 counting过程中的部分业务的 counting指示。
实施例七
图 8为本发明中 MBMS Counting Initiation信息发送示意图, 如图 8所 示, 本示例的 MBMS Counting Initiation信息中仅包括一个计数过程, 每个 计数过程中还包括若干个计数报告过程。 在该计数过程中至少包括若干个 业务的计数指示, 每个计数报告过程中也包括若干个业务的计数报告, 且 这些业务是计数过程中部分或全部业务。
M2接口上的 MBMS 业务的计数开始过程 ( M2 MBMS counting start procedure )具体包括以下步驟: 步骤 A、 MCE向 eNB发送 MBMS counting start request消息。
MCE向其 MBSFN区域的所有 eNB发送 MBMS counting start request 消息, 消息中包括: 需要计数的一个或多个 MBMS业务, 针对上述这些业 务, 还可以包括(也可以不包括)以下信息的一个或多个: counting的开始 时间 (start time ), 持续时间 ( duration time ), 才艮告时间 (report time )。
当该消息中包括报告时间时,下面的 "MCE eNB发送 MBMS counting report request消息"可以不进行, 即 MCE不再需要通过请求消息向 eNB配 置报告计数的结果。
报告时间的配置方式可以是 {业务 1 , 报告时间 1 ; 业务 2, 报告时间 2, .·· , 业务 n, ^艮告时间 n, } , 也可以统一为这些业务配置一个 4艮告时间, 即: 艮告时间; 业务 1 , 业务 2, .·· , 业务 n }。
还可以为每个业务配置多个 4艮告时间, 如{业务 1 , 4艮告时间 1 , 4艮告 时间 2, .·· , 报告时间 k}, 则表示 eNB在这些报告时间向 MCE报告计数 结果。
根据每个业务的报告时间或所有业务统一的报告时间, eNB向 MCE发 送 MBMS counting report response消息。
步骤 B、 eNB向 MCE发送 MBMS counting start response消息。
eNB接收到 MBMS counting start request消息, 且可以在空口上配置上 述业务的 counting指示和相关信息, 则 eNB向 MCE反馈 MBMS counting start response消息。
步驟 C、 eNB在 MCCH上配置上述业务的 counting指示。
步驟 C也可以在步驟 B之前进行, 或者同时进行。
在该步驟中, eNB 根据步驟 1 所配置的 counting 开始时间所指示的 MCCH修改周期, 在 MCCH更新时间将上述业务列表配置在 MCCH上。 如果步驟 A中没有配置 counting开始时间,则在下一个 MCCH修改周期的 MCCH更新时间将上述业务列表配置在 MCCH上;
在该步驟中, eNB根据步驟 A所配置的 counting持续时间, 在 MCCH 上一直配置上述业务的列表。如果根据步驟 A没有配置 counting持续时间, 在 MCCH上一直配置上述业务的列表。
步驟 D, UE读取 MCCH消息, 并向 eNB上报其感兴趣和 /或正在接收 的 MBMS业务。
该步驟在步驟 C之后。 eNB控制下小区中 UE读取 MCCH消息, 根据 MCCH消息中所配置的需要 counting的业务列表, 向 eNB上报其感兴趣和 /或正在接收的 MBMS业务。
在 MCCH消息中用于计数的每个业务, 还可以包括一个计数标识(如 序列号 SN, 即 serial number或 sequence number ), 用于区别不同的步骤 D。
比如, 某个 UE读取到 MCCH, 该 MCCH上用于 counting的业务列表 表示为: {业务 1 , SN1 } , {业务 2, SN2} , {业务 3, SN3 } , …, {业务 n, SNn} , 针对每个业务的计数标识 SN, UE仅上报 1次计数结果, 可以防止 eNB将一个 UE的计数结果重复统计也可以减少 UE上 4艮多次的上行信令开 销。
M2接口上的 MBMS 业务的 counting报告过程( M2 MBMS counting report procedure )具体包括以下步骤:
步骤 Al , MCE eNB发送 MBMS counting report request消息
如果 MCE eNB发送 MBMS counting start request消息中包括 "报告时 间 report time", 则该步驟不需要。
MCE向其 MBSFN区域的所有 eNB发送 MBMS counting report request 消息,消息中包括(也可以不包括):需要 4艮告计数结果的一个或多个 MBMS 业务。 这些 4艮告计数的若干 MBMS业务可以是 MBMS 业务 counting开始 过程中所配置的部分或全部; 还可以包括(或不包括)报告计数结果的时 刻( report time ) (也就是在哪个 MCCH修改周期结束后报告 counting结果); 还可以包括(或不包括)这些已经上报结果的业务的更新后计数标识( SN )。
该消息中如果没有包括用于报告计数结果的 MBMS业务列表, 则表示
MCE请求 eNB报告 "MBMS 业务 counting开始过程" 中所配置的全部业 务。
该消息中如果没有包括 " report time" , 即: 采用默认的报告时间, 则 表示 eNB收到该请求消息后, 在下一个 MCCH修改周期的 MCCH更新时 间, 统计该消息中所述业务的计数结果, 并上 4艮给 MCE。
该消息中如果包括每个业务的 "更新的计数标识", 则表示 UE不需要 重新上报计数结果给 eNB。 也就是说: UE根据 MCCH上某个业务的计数 标识, 一个业务的计数标识只上报一次该业务的计数结果给 eNB。
步骤 Bl , eNB向 MCE发送 MBMS counting report response消息。 eNB根据 " MBMS counting report request消息" 中所指定的报告时间
"report time" (该报告时间可以是默认的报告时间),或者根据 "MCE eNB 发送 MBMS counting start request消息" 所配置的报告时间, 统计 "MBMS counting report request消息" 中所述业务的计数结果, 即: 在指定 4艮告时间 将计数结果报告给 MCE。
这些已经上报结果的业务的计数标识(SN )可以不更新, 另外, 还可 以同时将这些已经上报结果的业务的计数标识(SN ) 更新为一个新计数标 识(如: SN+1 )。 该在 MCCH上更新若干业务的计数标识的时刻必须发生 在 MCCH更新时间。 也就是说, 在步驟 1所指定的报告时间, eNB—方面 向 MCE上 ^艮这些业务的计数结果并同时在 MCCH更新时间更新这些业务 的计数标识, 这样的话, UE读取 MCCH后可以获得这些业务新的计数标 识并需要重新上报其感兴趣和 /或正在接收业务, 也就是说: 对于 UE而言 是个新的计数。
比如, UE读取 MCCH的 counting的业务列表为 {业务 1 , SN1 } , {业 务 2, SN2} , {业务 3, SN3} , …, {业务 n, SNn} , UE上报一次其其感兴 趣和 /或正在接收业务; eNB向 MCE上报一次统计结果后, eNB在 MCCH 修改周期更新 MCCH的内容, 包括更新的计数标识为: {业务 1 , SN1+1 } , {业务 2, SN2+1 } , {业务 3, SN3+1 } , …, {业务 n, SNn+1 } , 此时 UE再 读取 MCCH后, 发现这些业务的计数标识已经更新, 则 UE需要重新向上 报 1次其感兴趣和 /或正在接收业务。
当 MCE根据上述的计数报告过程, 可以判决激活 /去激活一个或多个 业务的 counting之后, MCE可以向 eNB删除这些业务的 counting请求。
M2接口上的 MBMS 业务的 counting结束过程( M2 MBMS counting stop procedure )具体包括以下步驟:
步驟 A2, MCE向 eNB发送 MBMS counting sto 消息。
消息中, 包括原先配置在 MCCH上用于 counting的业务列表中的若干 业务, 用于指明这些业务不再需要 UE上报计数结果。
步驟 B2, eNB向 MCE发送 MBMS counting stop acknowledge消息 eNB接收到步驟 A2的请求消息后, 向 MCE发送确认消息。
步驟 C3, eNB在 MCCH上删除若干业务的计数指示及其相关信息。 当 "M2接口上的 MBMS 业务的 counting开始过程" 中包括若干业务 的持续时间时, 对于这些业务不需要步驟 A2和步驟 B2, 即在该 /这些业务 的持续时间到达后, 直接执行该步驟 C3。
根据 "MBMS counting stop消息"所配置的若干业务列表,或者当 "M2 接口上的 MBMS 业务的 counting开始过程"中包括若干业务的持续时间且 持续时间到, eNB在 MCCH更新时间, 修改 MCCH内容, 也就是删除这 些业务的 counting指示及相关信息。
该步驟可以在步驟 B2同时或者之前, 但需要在步驟 A2之后, 即 eNB 一旦接收到计数停止消息后就可以执行该步驟。
例如,在 "MCE eNB发送 MBMS counting start request消息,,后, eNB 在 MCCH上配置了用于 counting的业务为: {业务 1 , 相关信息 1 } , {业务 2, 相关信息 2} , {业务 3, 相关信息 3} , .·· , {业务 n, 相关信息 n}, 这 些相关信息可以是: 开始时间、 持续时间、 报告时间等。
当 "MCE eNB发送 MBMS counting sto 消息" 且包括业务 2 (指明 业务 2不再需要 UE上报, 即: eNB不再需要统计业务 2的计数结果)后, eNB在 MCCH上配置的用于 counting的业务为: {业务 1 ,相关信息 1 } , { {业 务 3, 相关信息 3} , .·· , {业务 n, 相关信息 n}, UE读取 MCCH后上报的 计数结果中不再包括于业务 2。
M2接口上的 MBMS 业务的 counting更新过程( M2 MBMS counting update procedure ) 与 "M2接口上的 MBMS 业务的 counting开始过程,, 相 似,也就是说可以通过 M2接口上的 MBMS 业务的 counting开始过程配置 每个业务的计数指示和相关信息 (相关信息包括: 开始时间, 持续时间, 报告时间等)。
