Definitions
- the present invention relates to the field of communications technologies, and in particular, to a multimedia broadcast multicast service (MBMS) service counting method and system.
- MBMS multimedia broadcast multicast service
- the 3rd Generation Partnership Project (3GPP) proposed MBMS, which is a technology for transmitting data from one data source to multiple targets, implementing the network (including the core).
- Network and access network Sharing of resources increases the utilization of network resources (especially air interface resources).
- the MBMS service defined by 3GPP can not only realize the multicast and broadcast of plain text low-rate message classes, but also realize the broadcast and multicast of high-speed multimedia services, and provide a variety of rich video, audio and multimedia services, which undoubtedly conforms to the future.
- 3G third-generation
- the MBMS service is introduced in the LTE Release 9 (R9) system and optimized in LTE Release 10 (R10).
- the MBMS service carries a common transmission of control signaling (also called MBMS control signaling) and user data (also known as MBMS service) in the system. Implement it.
- the control signaling will inform the receiving end (such as the terminal, the user equipment UE) corresponding control parameters, and direct the UE to the corresponding location to receive the MBMS service (ie, corresponding user data) of interest.
- the control signaling is transmitted in the LTE R9 and R10 systems through a Multicast Control Channel (MCCH), a Broadcast Control Channel (BCCH), and MCH Scheduling Information (MSI).
- MCCH Multicast Control Channel
- BCCH Broadcast Control Channel
- MSI MCH Scheduling Information
- MTCH Multicast Traffic Channel
- the MBSFN Area (MBSFN Area) is composed of a series of cells, generally including one or more.
- eNB evolved base station node 1
- the MBSFN area (such as in a circle) includes 19 cells, where eNB1 controls cell 1, cell 2 cell 6; eNB2 controls cell 7, cell 8 cell 13; eNB3 controls cell 14, cell 15 cell 19.
- MBSFN multi-cell/multicast Coordination Entity
- an MBMS-related network element has an eNB, an MCE, and an MBMS gateway (MBMS Gateway, MBMS).
- GW Broadcast Multicast Service Centre
- MME Mobility Management Entity
- BM-SC Broadcast Multicast Service Centre
- MME Mobility Management Entity
- the MME forwards the control plane information sent by the MBMS GW to the MCE through the M3 interface.
- the MCE sends the corresponding control plane information to the corresponding eNB. Through such processing, the eNB will obtain MBMS service data and corresponding control plane information.
- the UE uplink feedback mechanism is introduced. Specifically, the uplink feedback mechanism is mainly applied to the number of users (or the number of UEs) that are interested in receiving/receiving each MBMS service on the network side; Obtain the number of users to optimize the transmission of MBMS services, for example: deactivation, or not to send, interested/receiving MBMS services with a small number of users, activation (or called) Receives a large number of MBMS services.
- the network side may send an uplink command to the UE that is interested in receiving/receiving the MBMS service by sending a counting command (counting command). , telling the UE that the status of the MBMS is currently received.
- the network side may apply the information obtained through the uplink feedback (ie, how many interested/received UEs for a certain MBMS) to the activation or deactivation operation of the MBMS service; in other words, The network side may determine, according to the information obtained by the uplink feedback, whether the MBMS service is sent (deactivated) on the air interface.
- FIG. 3 shows a flow of an existing MBMS service counting method. Specifically, as shown in FIG. 3, when some MBMS services need to be counted, these MBMSs need to be counted.
- the service is referred to as a service to be counted, or a service, or an MBMS service in the present invention.
- Step 1 The MCE first configures an MBSFN area to be counted service for the eNB by using an MBMS SERVICE COUNTING REQUEST message, and each MBMS SERVICE COUNTING REQUEST message can only contain one MBSFN area to be counted, and The total number of business is up to 16;
- Step 2 The eNB sends an MBMS SERVICE COUNTING RESPONSE message to the MCE in response to the received counting request from the MCE. If the eNB fails to perform step 1 correctly, the eNB sends an MBMS service count failure (MBMS SERVICE COUNTING) Failure ) message to MCE;
- MBMS SERVICE COUNTING MBMS SERVICE COUNTING
- Step 3 The eNB sends a Counting Request message on the MCCH corresponding to the MBSFN area.
- the UE receives the Counting Request message carried on the MCCH, and learns that the eNB is counting the number of users, that is, the MBMS that is counting.
- the MBMS service count request message sent by the MCE to the eNB includes an activation time, which is used by the eNB to update the MCCH message, to ensure that the eNB can carry the MBMS service count message on the MCCH at the same time to be sent to the UE.
- Step 4 The corresponding UE (ie, the UE that is interested in and/or receiving the MBMS service for counting) feeds back to the eNB by using a Counting Response message; considering that the number of corresponding UEs in the eNB may be large, The eNB will collect corresponding feedback information for a period of time, which may be an MCCH Modification period, such as: 5.12 seconds or 10.24 seconds;
- Step 5 After the eNB completes the collection of the UE feedback information, the eNB reports the corresponding statistics to the MCE, that is, the eNB sends an MBMS SERVICE COUNTING RESULTS REPORT message to the MCE.
- steps 1 and 2 are performed by using an M2 interface between the MCE and the eNB to start the MBMS service counting process.
- Steps 3 and 4 are performed by using the Uu between the eNB and the UE.
- the interface is configured to complete the eNB to configure the to-be-counted service on the MCCH, the UE receives the to-be-counted service, and the UE feeds back the counting result to the eNB.
- Step 5 uses the M2 interface between the MCE and the eNB, and the eNB reports the counting result to the MCE.
- a complete MBMS Service Counting process should include the MBMS service count initiation process in steps 1 and 2, the MBMS service counting process in steps 3 and 4, and the MBMS service counting result reporting process in step 5. . That is to say: MCE starts an MBMS service counting process, and obtains the counting result of the MBMS service, and then completes an MBMS service counting process.
- the MCE when the MCE-triggered service to be counted belongs to multiple MBSFN areas, the MCE must send multiple MBMS SERVICE COUNTING REQUEST messages to count (each request message includes only one MBSFN area to be counted) Or when the MCE-triggered service to be counted belongs to one MBSFN area but the number of services is greater than 16, the MCE needs to send multiple MBMS SERVICE COUNTING REQUEST messages to count (each request message includes at most 16 services).
- the MCE when the MCE receives multiple (more than 16) services that need to be counted from the carrier or services that need to be counted in multiple MBSFN areas, the MCE needs to send more The MBMS SERVICE COUNTING REQUEST message is counted, that is, the MCE needs to start multiple MBMS SERVICE COUNTING processes.
- the current problem is that each time the MCE completes an MBMS counting process, it mainly takes a lot of time, at least 5 seconds, due to the processing time of the eNB on the air interface. If the MCE completes multiple MBMS service counting processes in sequence, that is, the MCE completes an MBMS service counting process and executes the next one, it takes a lot of time, and the counting result exists in real time, if the counting result of some services is fed back to the MCE It is too late for practical use.

- FIG. 4 shows a flow of the MBMS service counting method of the present invention. As shown in FIG. 4, the method includes the following steps:
- Step 41 The MCE starts multiple MBMS service counting processes in parallel;
- the MCE sends an MBMS service count request message to the eNB in the MBSFN area to start an MBMS service count process, when the MCE receives the MBMS SERVICE COUNTING RESPONSE message returned by the eNB. Indicates that the MCE successfully starts the MBMS service counting process. At this time, the MCE can start the next MBMS service counting process.
- the MCE when the MCE receives the MBMS SERVICE COUNTING failure message returned by the one or more eNBs, it indicates that the MCE has not successfully started the MBMS service counting process. At this time, the MCE can:
- the MCE restarts the MBMS service counting process, specifically, repeatedly sending an MBMS service request message to the eNB, until receiving the success response message returned by the eNB to the MBMS service request message, starting the next MBMS service counting process. start up;
- the MCE restarts the MBMS service counting process several times. If the failure occurs, the MBMS service counting process that fails to start is abandoned, and the next MBMS service counting process is started.
- the number of times the MCE restarts the MBMS service counting process may be The user can set it in advance according to the need;
- MCE abandons the MBMS service counting process that failed to start, and starts to start the next one. MBMS service counting process.
- Step 42 After the MBMS service counting process is successfully started, the eNB performs a successful MBMS service counting process on the air interface, and collects feedback information of the UE.
- e NB transmits a request count (Counting Request) message on the MCCH corresponding to the MBMS area, received by the UE carried on the MCCH Counting Request message, the eNB is informed user statistics, i.e. being counted MBMS Then, the corresponding UE, that is, the UE that is receiving the counted MBMS service or the UE that is interested in it, feeds back to the eNB through a Counting Response message; since the number of corresponding UEs under the eNB may be large, the eNB The corresponding feedback information will be collected for a period of time, which may be an MCCH Modification period, such as: 5.12 seconds or 10.24 seconds;
- the MBMS service count request message sent by the MCE to the eNB includes an activation time for the eNB to update the MCCH message time (MCCH update time) to ensure that the eNB can carry the MBMS service count message on the MCCH at the same time. Upload to the UE.
- the MCEs may be configured with the same or different activation times for different MBMS service counting processes belonging to different MBSFN areas, because the MCCHs of different MBSFN areas are different.
- the MCE When the MCE initiates multiple MBMS service counting processes in parallel, for a plurality of MBMS service counting processes belonging to the same MBSFN area, for example, when the operator needs to count 40 MBMS services in one MBSFN area, the maximum number of MBMS service counting processes is Only 16 services to be counted can be configured. Therefore, the MCE needs to configure these services on multiple MBMS service counting processes. In this case, the activation time of these MBMS service counting procedures is not allowed to be the same. Because it is the same MBSFN area, the corresponding MCCH is also the same, and the activation time of each MBMS service counting process is different, so that the MCCH can be guaranteed to be updated in different MCCHs. Time configures the service to be counted in each MBMS service count process.
- Step 43 the eNB reports the MBMS service count result to the MCE 4.
- the eNB reports the corresponding statistical result to the MCE, that is, the eNB sends an MBMS SERVICE COUNTING RESULTS REPORT message to the MCE.
- the sending time of the MBMS service counting result report message may also be different. That is to say: The MBMS service counting process started first, and the completion time of the process may not be earlier than the MBMS service counting process started later.
- the transmission of a certain MBMS service count result is not necessarily after the step 42 of another MBMS service counting process, and may also be before the eNB collects the feedback information of the UE in another MBMS service counting process. .
- the present invention also provides an MBMS service counting system.
- the structure of the system is shown in FIG. 5.
- the system includes: an MCE, an eNB, and a UE.
- the MCE is used to start multiple MBMS service counting processes in parallel.
- the eNB is configured to perform a successful MBMS service counting process, and collect feedback information of the UE, and report the MBMS service counting result to the MCE according to the collected feedback information of the UE.
- the eNB is an eNB included in an MBSFN area that transmits the multiple MBMS services, where the UE is interested in accessing the eNB, and is interested in or receiving the MBMS service. UE.
- the MCE is specifically configured to send an MBMS service count request message to the eNB, and send the next MBMS service count request message after receiving the MBMS service count response message returned by the eNB.
- the MCE is further configured to: after receiving the MBMS service count failure message returned by the eNB, resending the MBMS service count request message until receiving the eNB. Returning the MBMS service count response message; or, resending the MBMS service count request message according to the preset number of times, when the number of times of the transmission reaches the preset number of times, the MBMS service count response message returned by the eNB is still not received. Then, the next MBMS service counting process is started; or the next MBMS service counting process is directly started, and the next MBMS service counting request message is sent to the eNB.

Description
一种多媒体广播组播业务计数方法及系统 技术领域
本发明涉及通信技术领域, 尤其涉及一种多媒体广播组播(Multimedia Broadcast Multicast Service , MBMS )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移动终端的普及, 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 (3rd Generation Partnership Project, 3GPP )提出了 MBMS, 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(3rd Generation, 3G )数字通信的发展提供了更好的业务前景。
目前, 在 LTE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 )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)。
其中,控制信令在 LTE R9、 R10系统中是通过多播控制信道(Multicast Control Channel , MCCH )、广播控制信道( Broadcast Control Channel , BCCH ) 和 MCH调度信息(MCH Scheduling Information, MSI ) 来进行传输的; MBMS业务是通过多播业务信道 ( Multicast Traffic Channel, MTCH )来进 行传输的。
MBMS 控制信令和 MBMS 业务是以多播广播单频网络 (Multicast Broadcast Single Frequency Network, MBSFN )区域来进行传输的, MBSFN 区域( MBSFN Area )是由一系列小区所组成, 一般包括一个或多个由演进 基站节点(eNB )控制下的小区。 图 1为现有一 MBSFN区域的逻辑结构示 意图,如图 1所示,该 MBSFN区域(如圆圈内)包括 19个小区,其中 eNBl 控制小区 1、 小区 2 小区 6; eNB2控制小区 7、 小区 8 小区 13; eNB3控制小区 14、 小区 15 小区 19。
考虑到现有技术中, 在 MBSFN区域(如图 1中圆圈内的 19个小区构 成的一个 MBSFN区域)中发送 MBMS控制信令和 MBMS业务将以小区或 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区域内各个小区在相同 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。 目前使用网元多小区 /多播协调实体( Multi-cell/multicast Coordination Entity, MCE )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。
图 2为现有 MBMS控制系统结构示意图,如图 2所示,在现有系统中, 与 MBMS相关的网元有 eNB、 MCE、 MBMS网关( MBMS Gateway , MBMS
GW )、 广播组播业务中心 (Broadcast Multicast Service Centre, BM-SC ) 以 及移动性管理单元 (Mobility Management Entity, MME ), 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 ^口 Session Start message, Session Stop message, Session Updated 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。
为了进一步优化 MBMS业务发送, 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、或所述 UE的有 /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 <>
图 3示出了现有的一个 MBMS业务计数方法的流程, 具体而言, 如图 3所示, 当有些 MBMS业务需要计数的时候, 这些需要进行计数的 MBMS
业务在本发明中称为待计数业务、 或业务、 或 MBMS业务。
步驟 1 , MCE首先通过一个 MBMS业务计数请求(MBMS SERVICE COUNTING REQUEST )消息为 eNB配置一个 MBSFN区域的待计数业务, 且其中每条 MBMS SERVICE COUNTING REQUEST 消息仅能包含一个 MBSFN区域的待计数业务, 且业务的总数最多是 16个;
步驟 2, eNB向 MCE发送 MBMS业务计数响应 ( MBMS SERVICE COUNTING RESPONSE ) 消息来响应接收到的来自于 MCE的计数请求; 如果 eNB不能正确地执行步驟 1 ,则 eNB发送 MBMS业务计数失败( MBMS SERVICE COUNTING failure ) 消息给 MCE;
步驟 3, eNB将会在该 MBSFN区域所对应的 MCCH上发送计数请求 ( Counting Request )消息, UE通过接收 载在 MCCH上的 Counting Request 消息, 获知 eNB正在统计用户数的、 即正在进行计数的 MBMS业务;
这里, MCE发送给 eNB的 MBMS业务计数请求消息中包含有一激活 时间, 用于 eNB更新 MCCH消息的时间, 保证 eNB能够在同一时刻将该 MBMS业务计数消息 载在 MCCH上以发送至 UE。
步驟 4, 相应的 UE (即感兴趣和 /或正在接收进行计数 MBMS业务的 UE )通过计数响应 ( Counting Response )消息向 eNB进行反馈;考虑到 eNB 下相应 UE的个数可能是大量的, 所以 eNB将在一段时间内收集相应的反 馈信息, 这段时间可以是一个 MCCH 修改周期 (MCCH Modification period ), 如: 5.12秒或 10.24秒;
步驟 5, 当 eNB完成 UE反馈信息的收集后, eNB将会向 MCE上报相 应的统计结果, 即: eNB向 MCE发送 MBMS业务计数结果 4艮告(MBMS SERVICE COUNTING RESULTS REPORT ) 消息。
其中, 上述的步驟 1和步驟 2, 采用 MCE和 eNB之间的 M2接口, 用 于启动 MBMS业务计数过程; 步驟 3和步驟 4,采用 eNB与 UE之间的 Uu
接口, 用于完成 eNB在 MCCH上配置待计数业务, UE接收到待计数业务 和 UE向 eNB反馈计数结果; 步驟 5采用 MCE和 eNB之间的 M2接口, 用于 eNB向 MCE报告计数结果。
一个完整的 MBMS业务计数( MBMS Service Counting )过程应该包括 步驟 1和 2的 MBMS业务计数的启动过程, 步驟 3和 4中空口的 MBMS 业务的计数过程, 以及步驟 5的 MBMS业务计数结果的报告过程。 也就是 说: MCE启动了一个 MBMS业务计数过程, 并得到了 MBMS业务的计数 结果, 才算完成了一个 MBMS业务计数过程。
通过上面的分析, 可以看出, 当 MCE 触发的待计数业务属于多个 MBSFN区域, MCE必须发送多条 MBMS SERVICE COUNTING REQUEST 消息来进行计数(每条请求消息仅包括一个 MBSFN区域的待计数业务); 或者当 MCE触发的待计数业务属于 1个 MBSFN区域但业务数量大于 16 个,则 MCE需要发送多条 MBMS SERVICE COUNTING REQUEST消息来 进行计数(每条请求消息最多包括 16个业务)。 也就是说, 在许多情况下, 当 MCE接收到来自上级网元或者来自运营商配置的多个(大于 16个) 需 要计数的业务或者多个 MBSFN区域需要计数的业务的时候, MCE需要发 送多条 MBMS SERVICE COUNTING REQUEST消息来进行计数, 即 MCE 需要启动多个 MBMS SERVICE COUNTING 过程。
然而, 目前存在的问题是, MCE每完成一个 MBMS计数过程, 主要 由于 eNB在空口上的处理时间, 需要花费许多时间, 至少是 5秒以上。 如 果 MCE按顺序完成多个 MBMS业务计数过程, 即: MCE完成一个 MBMS 业务计数过程再执行下一个, 则需要花费许多时间, 而计数结果存在实时 性,如果有的业务的计数结果反馈到 MCE的时间太晚,是没有实际用途的。 发明内容
有鉴于此, 本发明的主要目的在于提供一种 MBMS业务计数方法及系
统, 能够并行执行多个 MBMS业务计数过程, 快速完成 MBMS业务计数。 为达到上述目的, 本发明的技术方案是这样实现的:
一种 MBMS业务计数方法, 该方法包括:
MCE并行启动多个 MBMS业务计数过程;
eNB执行启动成功的 MBMS业务计数过程, 并收集 UE的反馈信息; eNB根据收集到的 UE的反馈信息, 向 MCE报告 MBMS业务计数结 果。
其中, 所述 MCE并行启动多个 MBMS业务计数过程为:
MCE发送一个 MBMS业务计数请求消息至 eNB;
当 MCE接收到 eNB返回的 MBMS业务计数响应消息后 ,所述 MBMS 业务计数过程启动成功;
MCE启动下一个 MBMS业务计数过程, 发送下一个 MBMS业务计数 请求消息至 eNB。
进一步地, 在所述 MCE发送一个 MBMS业务计数请求消息至 eNB之 后, 所述方法还包括:
当 MCE接收到 eNB返回的 MBMS业务计数失败消息后, 重新启动该 MBMS业务计数过程,发送所述 MBMS业务计数请求消息至 eNB,直到接 收到 eNB返回的 MBMS业务计数响应消息; 或者,
MCE根据预设的次数, 重新启动该 MBMS业务计数过程, 发送所述 MBMS业务计数请求消息至 eNB, 当发送次数达到所述预设的次数, 仍未 接收到 eNB返回的 MBMS业务计数响应消息, 开始启动下一个 MBMS业 务计数过程; 或者,
MCE接收到 eNB返回的 MBMS业务计数失败消息时, 直接启动下一 个 MBMS业务计数过程, 发送下一个 MBMS业务计数请求消息至 eNB。
其中, 所述 eNB执行启动成功的 MBMS业务计数过程为:

具体实施方式
本发明的基本思想为: MCE并行启动多个 MBMS业务计数过程; eNB 执行启动成功的 MBMS业务计数过程, 并收集 UE的反馈信息; eNB根据 收集到的 UE的反馈信息, 向 MCE报告 MBMS业务计数结果。
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。
图 4示出了本发明的 MBMS业务计数方法流程, 如图 4所示, 所述方 法包括下述步驟:
步驟 41 , MCE并行启动多个 MBMS业务计数过程;
具体地, 本步驟中, MCE通过向 MBSFN区域中的 eNB发送 MBMS 业务计数请求消息, 以启动一个 MBMS业务计数过程, 当 MCE接收到该 eNB 返回的 MBMS 业务计数响应 ( MBMS SERVICE COUNTING RESPONSE ) 消息时, 表示所述 MCE成功地启动了这个 MBMS业务计数 过程, 此时, MCE可以启动下一个 MBMS业务计数过程。
这里, 当 MCE接收到一个或多个 eNB返回的 MBMS业务计数失败 ( MBMS SERVICE COUNTING failure ) 消息, 则表明 MCE没有成功地启 动该 MBMS业务计数过程, 此时, MCE可以:
1 ) MCE重新启动该 MBMS业务计数过程, 具体为重复地向 eNB发送 MBMS业务请求消息, 直到接收到所述 eNB对该 MBMS业务请求消息返 回的成功响应消息时, 开始下一个 MBMS业务计数过程的启动;
2 ) MCE重新启动若干次该 MBMS业务计数过程, 若失败, 则放弃该 启动失败的 MBMS业务计数过程, 开始启动下一个 MBMS业务计数过程; 这里, MCE重新启动该 MBMS业务计数过程的次数可以为用户根据需要 预先进行设置得到;
3 ) MCE放弃该启动失败的 MBMS 业务计数过程, 开始启动下一个
MBMS业务计数过程。
步驟 42, MBMS业务计数过程启动成功后, eNB在空口上执行启动成 功的 MBMS业务计数过程, 并收集 UE的反馈信息;
具体地, 首先, eNB在该 MBMS区域所对应的 MCCH上发送计数请 求(Counting Request ) 消息, UE通过接收承载在 MCCH上的 Counting Request消息, 获知 eNB正在统计用户数、 即正在进行计数的 MBMS业务; 然后, 相应 UE, 即正在接收进行计数的 MBMS业务或对其感兴趣的 UE通过计数响应 ( Counting Response ) 消息向 eNB进行反馈; 由于 eNB 下相应 UE的个数可能是大量的, 所以 eNB将在一段时间内收集相应的反 馈信息, 这段时间可以是一个 MCCH 修改周期 (MCCH Modification period ), 如: 5.12秒或 10.24秒;
这里, 在 MCE发送给 eNB的 MBMS业务计数请求消息中, 包含有一 激活时间, 用于 eNB更新 MCCH消息的时间 ( MCCH update time ), 以保 证 eNB能够在同一时刻将该 MBMS业务计数消息承载在 MCCH上以发送 至 UE。
当 MCE 并行地启动多个 MBMS 业务计数过程时, 对于属于不同 MBSFN区域的多个 MBMS业务计数过程, 由于不同的 MBSFN区域对应 的 MCCH也不同, 所以 MCE可以配置相同的或者不同的激活时间;
当 MCE 并行地启动多个 MBMS 业务计数过程时, 对于属于同一 MBSFN区域的多个 MBMS业务计数过程, 比如: 当运营商需要计数一个 MBSFN区域的 40个 MBMS业务, 由于每个 MBMS业务计数过程最多只 能配置 16个待计数业务,所以 MCE需要将这些业务分别配置在多个 MBMS 业务计数过程上。 在这种情况下, 这些 MBMS业务计数过程的激活时间不 允许相同。由于是同一个 MBSFN区域,对应的 MCCH也相同,每个 MBMS 业务计数过程的激活时间不同,才可以保证该 MCCH在不同的 MCCH更新
时间配置每个 MBMS业务计数过程中的待计数业务。
步驟 43, eNB向 MCE 4艮告 MBMS业务计数结果;
具体地, 当 eNB完成 UE反馈信息的收集后, eNB将会向 MCE上报 相应的统计结果, 即 eNB向 MCE发送 MBMS业务计数结果 4艮告 ( MBMS SERVICE COUNTING RESULTS REPORT ) 消息。
由于不同的 MBMS业务计数过程中 MCCH修改周期不同,所以 MBMS 业务计数结果报告消息的发送时间也会有所不同。 也就是说: 先启动的 MBMS业务计数过程,该过程的完成时间未必比后启动的 MBMS业务计数 过程早。
如此, 应当理解, 某一个 MBMS业务计数结果 ·^艮告信息的发送不一定 在另一个 MBMS业务计数过程的步驟 42之后, 也可以在另一个 MBMS业 务计数过程中, eNB收集 UE的反馈信息之前。
本发明还提供了一种 MBMS业务计数系统, 该系统的结构示意如图 5 所示, 所述系统包括: MCE、 eNB, 及 UE; 其中, MCE, 用于并行启动多 个 MBMS业务计数过程; eNB,用于执行启动成功的 MBMS业务计数过程, 并收集所述 UE的反馈信息, 根据收集到的所述 UE的反馈信息, 向所述 MCE报告 MBMS业务计数结果;
这里,所述 eNB为传输所述多个 MBMS业务的 MBSFN区域中包含的 eNB, 所述 UE为接入所述 eNB, 且对所述进行计数的 MBMS业务感兴趣 或正在接收所述 MBMS业务的 UE。
其中,所述 MCE,具体用于发送一个 MBMS业务计数请求消息至 eNB , 当接收到所述 eNB返回的 MBMS业务计数响应消息后 ,发送下一个 MBMS 业务计数请求消息。
其中, 所述 MCE, 还用于接收到所述 eNB返回的 MBMS业务计数失 败消息后, 重新发送所述 MBMS业务计数请求消息, 直到接收到所述 eNB
返回的 MBMS业务计数响应消息; 或者, 根据预设的次数, 重新发送所述 MBMS业务计数请求消息, 当发送次数达到所述预设的次数, 仍未接收到 eNB返回的 MBMS业务计数响应消息时, 则开始启动下一个 MBMS业务 计数过程; 或者直接启动下一个 MBMS业务计数过程,发送下一个 MBMS 业务计数请求消息至 eNB。
优选地, 所述 eNB, 具体用于按照接收到的 MBMS业务计数请求消息 中的激活时间,对 MCCH承载的消息进行更新,在 MCCH上发送计数请求 消息至 UE;
所述 UE, 用于反馈计数响应消息给所述 eNB。
另外, 当 MCE 并行启动的多个 MBMS 业务计数过程属于不同的 MBSFN区域的多个 MBMS业务计数过程时 ,所述 MCE发送的多个 MBMS 业务计数请求消息中的激活时间相同或不同;
当 MCE并行启动的多个 MBMS业务计数过程属于相同 MBSFN区域 的多个 MBMS业务计数过程时,所述 MCE发送的多个 MCE业务计数请求 消息中的激活时间互不相同。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围。
