- MBMS Multimedia Broadcast Multicast Service
- BACKGROUND With the rapid development of the Internet and the popularization of large-screen multi-function mobile phones, a large number of mobile data multimedia services and various high-bandwidth multimedia services have emerged, such as: video conferencing, television broadcasting, video on demand, video advertising, online education, and interaction. Games, etc., not only meet the rising business needs of mobile users, but also bring new business growth points to mobile operators.
- These mobile data multimedia services require multiple users to receive the same data at the same time. Compared with general data services, they have the characteristics of large data volume, long duration, and delay sensitivity.
- the 3rd Generation Partnership Project (3GPP) proposed the MBMS service, which is a technology that transmits data from one data source to multiple targets, and implements the network.
- the sharing of resources (including the core network and the access network) improves the utilization of network resources (especially air interface resources).
- the MBMS service defined by 3GPP can not only realize plain text low-rate message class multicast and broadcast, but also realize high-speed multimedia service broadcast and multicast, and provide a variety of rich video, audio and multimedia services, which are compatible with future mobile data.
- the development trend provides a better business prospect for the development of 3G (3rd Generation, Digital Communication).
- the MBMS service is transmitted by using the Multimedia Broadcast multicast service Single Frequency Network (MBSFN).
- MMSFN Multimedia Broadcast multicast service Single Frequency Network
- the network side initiates the statistics process (also called the counting process) of some MBMS services by the network side, and the network side sends a message containing the identifier of the MBMS service to be counted to the user equipment (User Equipment, UE for short).
- the UE determines whether it is receiving according to the MBMS service identifier included in the message, or if the MBMS service status included in the message is an unsent MBMS service, then it needs to determine whether it is interested in receiving.

- MCS Modulation and Coding Scheme
- the uplink resources allocated by the base station to the UE generally have a large redundancy difference.
- the smallest redundancy difference is 2 bytes, and in most cases, the redundancy difference is much larger than 2 bytes. For example, if the UE has 5 bytes of data to send, the base station also allocates 10 bytes of uplink resources to the UE, so that the MBMS status report can be transmitted by using the excess uplink resources. Why is there a large error in LTE?
- the main granularity of the physical resource block (PRB) in the current LTE system is large, and the granularity of the buffer status report (BSR) sent by the UE to the base station is large.
- the advantage of larger granularity is that the complexity of the scheduling algorithm of the system can be greatly reduced.
- the uplink resource is used to transmit the data that the terminal is uplinking, and the terminal can carry the MBMS status report while transmitting the uplink service data, for example, the terminal uses the network side device as the other service data that is about to be uplinked by the terminal.
- the uplink grant information and the MCS are configured to transmit the MBMS status report to the network side device.
- the step S204 includes: the terminal performs encapsulation processing on the MBMS status report and other service data at the MAC (Media Access Control) layer; the terminal uses the MCS in the uplink authorization information at the physical layer to encapsulate the MBMS.

- the terminal After the terminal performs channel coding and rate matching on the input data at the physical layer, the obtained data satisfies the size of the MCS and the uplink resource in the uplink authorization information, thereby implementing final data mapping and transmission. If the amount of encoded data exceeds the allocated amount of the uplink resource, the rate matching method is adopted to make the encoded data amount satisfy the allocated amount of the uplink resource.

- the information determines that an MBMS status report needs to be sent to the network side device. For example, after receiving the counting command sent by the network side device, the terminal parses the command and obtains information about the MBMS service that needs to perform feedback counting. The terminal determines whether it is needed according to the information of the MBMS service. The uplink feedback is performed to determine whether the MBMS status report needs to be transmitted.
- the feedback is based on the MBMS service corresponding to the information that the terminal is receiving the MBMS service or the MBMS service corresponding to the information that is interested in receiving the MBMS service.
- the network side device detects whether the received uplink data includes the MBMS status report. For example, after the counting command is sent by the network side device, until the end of the counting process, the network side device detects whether the uplink data carries the logical channel identifier corresponding to the MBMS status report, and if yes, determines that the uplink data carries the MBMS status report; otherwise, Then it is determined that the uplink data does not carry the MBMS status report.
- the network side device starts the MBMS counting process, in the counting process, it is required to detect whether the MBMS status report is included in the uplink data of the terminal, and the other time may not be detected. If the network side device parses the uplink data and obtains RRC (Radio Resource Control) information, the network side device needs to perform detection according to the specified RRC information. If the uplink data obtained by the parsing is a MAC CE, the network side device needs to perform detection according to the specified MAC CE. The specific detection method depends on the terminal's MBMS status report transmission form.
- RRC Radio Resource Control
- the MBMS status report is sent to the network side together with the other service data by using the uplink authorization information allocated by the other service data, and the problem that the terminal sends the MBMS status report is slow, and the terminal can quickly send the MBMS status report to the terminal.

- the base station requires the same rate rate information in the uplink grant information allocated by the UE for transmitting other service data, and then uses the modulation mode information in the uplink grant information to perform modulation processing on the further obtained data.
- the processing of the foregoing transport block by the UE at the physical layer needs to be processed according to the requirements of the foregoing uplink grant information.
- the uplink authorization information is configured by the base station to transmit the foregoing other service data to the UE, and is not configured for the uplink transmission of the MBMS status report data by the UE.
- Step S308 the base station detects the received uplink data, and obtains an MBMS status report from the uplink data. After the base station sends the command of the counting process, the base station considers that it is already in the period of a counting process, so the base station needs to detect whether the data of the MBMS status report is included in the uplink data of the UE. Since the time point at which the UE uplinks the MBMS status report is random and cannot be estimated in advance, the base station needs to detect one by one.
- the base station can identify whether the UE has MBMS capability, then the base station can only target The uplink data of the MBMS-capable UE is detected, and it is detected whether the uplink data of the UE includes the data of the MBMS status report.

Description
MBMS状态报告的发送方法、 系统、 终端和网络侧设备 技术领域 本发明涉及通信领域,具体而言,涉及一种 MBMS (Multimedia Broadcast Multicast Service, 多媒体广播组播业务) 状态报告的发送方法、 系统、 终端和网络侧设备。 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 MBMS业务, 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, 顺应了未来移动数据的发展趋势, 为 3G (3rd Generation, 第三代 数字通信) 的发展提供了更好的业务前景。 在长期演进 (Long Term Evolution, 简称 LTE) 系统中, MBMS业务采用多媒体 广播组播业务单步] ¾网 (Multimedia Broadcast multicast service Single Frequency Network, 简称 MBSFN) 方式进行发送。 网络侧针对一些 MBMS业务的统计过程 (也叫计数过 程)由网络侧发起, 同时网络侧下发一个包含着需要被统计的 MBMS业务的标识的消 息给用户设备(User Equipment, 简称 UE), 相关的 UE接收到这条消息后, 根据消息 中包含的 MBMS业务标识,判断自己是否正在接收,或者,如果消息中包含的 MBMS 业务状态为未发送的 MBMS业务, 那么则需要判断是否感兴趣接收。最后 UE侧针对 消息中的标识对应的 MBMS 业务形成相应的响应信息, 例如 CR ( Counting Report message, 计数报告消息), 本申请中将该响应信息用 "MBMS状态报告"表示, 该报 告的作用是向网络侧反馈 UE正在接收的 MBMS业务或者感兴趣接收的 MBMS业务 的信息。 图 1示出了相关技术中 UE向网络侧发送上行数据的方法流程图,具体流程如下:
步骤 S102, UE发起上行调度请求 (Scheduling Request, 简称 SR), 通知基站该 UE有上行数据需要进行传输, 这里假设 UE有自己的 SR资源, 并且该 UE与基站处 于连接状态 (RRC_connected 步骤 S104, 基站接收到 SR请求后, 为该 UE分配上行资源, 其中, 上行资源是 为 UE分配的用来传输缓存状态报告 (Buffer Status Report, 简称 BSR) 的资源, 该资 源比较小, 仅仅用于 UE上报 BSR。 BSR在 LTE 36.321中进行了定义, 分为两种, 一 种是短的 BSR, 大小为 8 bits ( 1个字节), 长的 BSR大小为 24 bits (3个字节)。 所以 该步骤中基站分配的资源比较小, 只要保证能够传输长的 BSR即可。 步骤 S106, UE在步骤 S104中分配的上行资源中发送 BSR报告给基站。 BSR中 携带 UE需要传输的上行数据的大小信息。 步骤 S108, 基站根据接收到的 UE的 BSR, 结合 UE的测量结果等, 为 UE分配 适合的上行资源。 通过上述步骤 S106和步骤 S108可以实现按照 UE需求进行上行资源的分配, 避 免了上行资源的浪费。 步骤 S110, UE在步骤 S108分配的上行资源中发送上行数据给基站。 由图 1所示流程可知, UE请求调度的过程比较复杂, 如果发送 MBMS状态报告 采用该流程, UE发送 MBMS状态报告所需的时间将会比较长, 导致网络侧对 MBMS 业务的统计过程 (或计数过程) 的耗时较长, 并且系统资源的利用率也较差。 发明内容 本发明在于提供一种 MBMS状态报告的发送方法、系统、终端和网络侧设备, 以 解决上述 MBMS状态报告发送所需的时间较长的问题。 根据本发明的一个方面,提供了一种 MBMS状态报告的发送方法,包括以下步骤: 终端确定需要向网络侧设备发送的 MBMS状态报告;终端使用网络侧设备已为其他业 务数据分配的上行授权信息发送 MBMS状态报告和其他业务数据,其中,其他业务数 据为除 MBMS状态报告之外的业务数据。 上述终端使用网络侧设备已为其他业务数据分配的上行授权信息发送 MBMS 状 态报告和其他业务数据包括: 在媒体接入控制 MAC层对 MBMS状态报告和其他业务 数据进行封装处理; 在物理层使用上行授权信息中的编码调制信息 MCS 要求对封装
后的 MBMS状态报告和其他业务数据进行信道编码、速率匹配、调制操作, 将操作后 的数据映射到上行授权信息中指示的上行资源中发送。 上述终端在 MAC层对 MBMS状态报告和业务数据进行封装处理包括:按照 MAC 业务数据单元 SDU的封装格式对 MBMS状态报告进行封装, 按照 MAC SDU或者 MAC 控制单元 CE的封装格式对其他业务数据进行封装; 将封装后的 MBMS状态报 告和其他业务数据封装在一个 MAC协议数据单元 PDU中。 上述终端封装后的 MBMS状态报告中携带有 MBMS状态报告对应的逻辑信道标 识; 相应地, 上述终端封装后的其他业务数据中携带有其他业务数据对应的逻辑信道 标识。 上述终端确定需要向网络侧设备发送 MBMS状态报告之前, 上述方法还包括: 网 络侧设备启动 MBMS计数过程, 向终端发送计数命令, 其中, 该计数命令携带有需要 进行反馈计数的 MBMS业务的信息; 上述终端确定需要向网络侧设备发送 MBMS 状态报告包括: 根据计数命令中的 MBMS业务的信息确定需要向网络侧设备发送 MBMS状态报告。 上述终端使用网络侧设备已为其他业务数据分配的上行授权信息发送 MBMS 状 态报告和其他业务数据之后, 上述方法还包括: 网络侧设备在计数命令发送后, 直到 本次计数过程结束,网络侧设备检测接收到的终端的上行数据中是否包含 MBMS状态 报告。 上述网络侧设备检测接收到的终端的上行数据中是否包含 MBMS状态报告包括: 检测接收到的终端的上行数据是否携带有 MBMS状态报告对应的逻辑信道标识,如果 是, 确定上行数据携带有 MBMS状态报告。 上述 MBMS状态报告包括下述信息的一个或者多个:标识终端正在接收或者感兴 趣接收的 MBMS业务的信息; 标识 MBMS状态报告对应的多媒体广播组播业务单频 网 MBSFN区域的信息; 标识 MBMS状态报告对应的计数过程的信息。 根据本发明的另一方面, 提供了一种 MBMS状态报告的发送系统, 包括: 网络侧 设备和终端,其中,终端包括:确定模块,设置为确定需要向网络侧设备发送的 MBMS 状态报告; 发送模块, 设置为确定模块确定需要发送的 MBMS状态报告后, 使用网络 侧设备已为其他业务数据分配的上行授权信息发送 MBMS状态报告和其他业务数据,
其中, 其他业务数据为除 MBMS状态报告之外的业务数据; 该网络侧设备包括: 检测 模块, 设置为检测接收到的上行数据中是否包含 MBMS状态报告。 根据本发明的又一方面, 提供了一种终端, 该终端包括: 确定模块, 设置为确定 需要向网络侧设备发送多媒体广播组播业务 MBMS状态报告; 发送模块, 设置为确定 模块确定需要发送 MBMS状态报告后,使用网络侧设备已为其他业务数据分配的上行 授权信息发送 MBMS状态报告和其他业务数据, 其中, 其他业务数据为除 MBMS状 态报告之外的业务数据。 根据本发明的再一方面, 提供了一种网络侧设备, 该网络侧设备包括: 计数命令 发送模块,设置为启动多媒体广播组播业务 MBMS的计数过程,向终端发送计数命令, 其中, 计数命令携带有需要进行反馈计数的 MBMS业务的信息; 检测模块, 设置为在 计数命令发送后, 直到本次计数过程结束, 检测接收到的上行数据中是否包含 MBMS 状态报告。 通过本发明,采用终端直接使用已经分配的上行授权信息传输 MBMS状态报告给 网络侧设备,解决了终端发送 MBMS状态报告速度慢的问题,保证了网络侧设备及时 地获取到终端上行发送的 MBMS状态报告。 并且避免了终端为发送 MBMS状态报告 而申请上行资源的流程, 提升计数过程的效率, 也节省了系统的资源。 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是根据相关技术的 UE向网络侧发送上行数据的方法流程图; 图 2是根据本发明实施例 1的 MBMS状态报告的发送方法流程图; 图 3是根据本发明实施例 2的 MBMS状态报告的发送方法流程图; 图 4是根据本发明实施例 3的 MBMS状态报告的发送系统的结构框图; 图 5是根据本发明实施例 4的终端的结构框图; 图 6是根据本发明实施例 5的网络侧设备的结构框图。
具体实施方式 下文中将参考附图并结合实施例来详细说明本发明。 需要说明的是, 在不冲突的 情况下, 本申请中的实施例及实施例中的特征可以相互组合。 本发明实施例考虑到 MBMS状态报告的数据量比较小 (通常为 1~3个字节), 所 以直接借用网络侧设备(例如: 基站)为终端(即 UE)分配的上传其他业务数据的上 行资源来传输 MBMS状态报告。 基于此, 本发明实施例提供了一种 MBMS状态报告 的发送方法、 系统、 终端和网络侧设备, 其中, 终端可以是用户设备 UE, 网络侧设备 可以是基站等。 实施例 1 图 2示出了根据本发明实施例的 MBMS状态报告的发送方法流程图,该方法包括 以下步骤: 步骤 S202, 终端确定需要向网络侧设备发送的 MBMS状态报告; 其中, MBMS状态报告包括下述信息的一个或者多个: 标识终端正在接收或者感 兴趣接收的 MBMS业务的信息; 标识 MBMS状态报告对应的多媒体广播组播业务单 频网 MBSFN区域的信息; 标识 MBMS状态报告对应的计数过程的信息。 步骤 S204,终端使用上述网络侧设备已为该终端的其他业务数据分配的上行授权 (uplink grant)信息来发送 MBMS状态报告和其他业务数据, 其中, 其他业务数据为 除 MBMS状态报告之外的业务数据。 其中, 上行授权信息包括: 为该终端分配的传输其他业务数据的上行资源信息 (Resource block assignment)禾口编码调制信息(Modulation and Coding Scheme, MCS) 等, 具体可以参考 LTE协议 36.212协议的 5.3.31.1章节中的描述。 这里基站为 UE分 配的上行资源一般都具有较大的冗余差, 目前最小的冗余差是 2个字节, 并且绝大部 分情况下冗余差远大于 2个字节。例如, UE有 5个字节的数据需要发送, 那么基站也 会分配可以传输 10 个字节的上行资源给 UE, 这样就可以利用多余的上行资源传输 MBMS状态报告。 LTE中为什么会有较大的误差,这里主要取决于当前 LTE系统中物 理资源块 (PRB) 的基本颗粒度较大, 以及 UE发送给基站的缓存状态报告 (BSR) 的颗粒度较大造成的, 但是较大的颗粒度的好处是可以使得系统的调度算法的复杂度 大大降低。
当处于连接状态的终端需要进行 MBMS状态报告发送时,如果该终端已经拥有了 网络侧设备分配的上行资源 (例如这个终端正在和网络侧设备进行上行数据传输, 所 以该终端拥有网络侧设备分配的上行资源, 但是这个上行资源是用来传输终端正在上 行的数据的),那么终端可以在发送上行业务数据的同时携带 MBMS状态报告,例如: 终端使用网络侧设备为自己即将上行传输的其他业务数据 (非 MBMS 状态报告的数 据) 配置的上行授权信息中上行资源和 MCS等信息来上行传输 MBMS状态报告给网 络侧设备。 优选地, 步骤 S204包括: 终端在 MAC (Media Access Control, 媒体接入控制) 层对 MBMS状态报告和其他业务数据进行封装处理;该终端在物理层使用上行授权信 息中的 MCS对封装后的 MBMS状态报告和其他业务数据进行信道编码、 速率匹配、 调制操作, 并将操作后的数据映射到上行授权信息指示的上行资源中发送。 终端在物理层通过对输入的数据进行信道编码、 速率匹配后使得到的数据满足上 述上行授权信息中 MCS 和上行资源的大小, 从而实现最后的数据映射和发送。 如果 编码后的数据量超过了所分配的上行资源的承载量, 那么则采用速率匹配的方法使得 编码后的数据量满足所分配的上行资源的承载量。 其中, 终端在 MAC层对 MBMS状态报告和业务数据进行封装处理包括: 该终端 按照 MAC SDU的封装格式对 MBMS状态报告进行封装, 按照 MAC SDU或者 MAC CE (Control Element, 控制单元) 的封装格式对其他业务数据进行封装; 终端将封装 后的 MBMS状态报告和其他业务数据封装在一个 MAC PDU (Protocol Data Unit, 协 议数据单元) 中。 为了方便网络侧检测上行数据是否携带 MBMS状态报告,本发明实施例的终端按 照 MAC SDU的封装格式对 MBMS状态报告进行封装,按照 MAC SDU或者 MAC CE 的封装格式对其他业务数据进行封装包括: 终端按照 MAC SDU的封装格式对 MBMS 状态报告进行封装, 其中, 封装后的 MBMS状态报告中携带有 MBMS状态报告对应 的逻辑信道标识;终端按照 MAC SDU或者 MAC CE的封装格式对其他业务数据进行 封装, 封装后的其他业务数据中携带有其他业务数据对应的逻辑信道标识。 上述步骤 S202之前, 该方法还包括: 网络侧设备启动 MBMS计数过程, 向上述 终端发送计数命令,其中,该计数命令携带有需要进行反馈计数的 MBMS业务的信息; 终端根据计数命令中的 MBMS业务的信息确定需要向网络侧设备发送 MBMS状态报 告。 例如: 当终端接收到网络侧设备发送的计数命令后, 解析该命令, 并从中获取需 要进行反馈计数的 MBMS业务的信息。 终端根据该 MBMS业务的信息判断是否需要
进行上行反馈, 即判断是否需要传输 MBMS状态报告,本实施例中需要反馈的依据是 终端正在接收该 MBMS业务的信息对应的 MBMS业务或者感兴趣接收该 MBMS业务 的信息对应的 MBMS业务。 上述步骤 S204之后, 网络侧设备检测接收到的上行数据中是否包含上述 MBMS 状态报告。 例如: 网络侧设备在计数命令发送后, 直到本次计数过程结束, 网络侧设 备检测上行数据是否携带有 MBMS状态报告对应的逻辑信道标识, 如果是,确定上行 数据携带有 MBMS状态报告; 否则, 则确定该上行数据中没有携带 MBMS状态报告。 优选地, 网络侧设备若是启动 MBMS计数过程, 则在该计数过程中, 需要检测终 端的上行数据中是否包含上述 MBMS状态报告, 其它时间可以不用检测。 如果网络侧设备解析上行数据后, 得到 RRC (Radio Resource Control, 无线资源 控制)信息, 网络侧设备需要按照规定的 RRC信息进行检测。如果解析得到的上行数 据是 MAC CE, 那么网络侧设备需要按照规定的 MAC CE进行检测。具体检测方式取 决于终端的 MBMS状态报告发送形式。 本实施例通过使用其他业务数据所分配的上行授权信息,将 MBMS状态报告与其 他业务数据一起发送给网络侧,解决了终端发送 MBMS状态报告较慢的问题, 终端能 够快速把 MBMS状态报告发送给网络侧设备, 提升了 MBMS业务的计数效率以及系 统的资源利用率。 实施例 2 本实施例假设网络侧对某一 MBSFN区域内的一些 MBMS业务发起 MBMS计数 过程, 本实施例具体由 MCE配置相关的计数过程的计数命令, 并把计数命令发送给 相关基站,基站把相关计数命令通过多播控制信道(Multicast Control Channel, MCCH) 发送给 UE。基站把发送计数命令的时刻记做本次计数过程的起始时间点,之后直到本 次计数过程结束,基站都需要对 UE的上行数据进行是否包含 MBMS状态报告的检测 处理。 图 3示出了根据本发明实施例的 MBMS状态报告的发送方法的流程图,该方法包 括以下步骤: 步骤 S302, 基站将计数命令通过 MCCH发送给 UE, 其中, 该计数命令携带有 MBMS业务的信息。
步骤 S304, 当 UE接收到基站发送的计数命令后, 解析该命令, 并从中获取需要 进行反馈计数的 MBMS业务的信息。 UE根据该 MBMS业务的信息判断是否需要进行 上行反馈, 即给基站是否需要传输 MBMS状态报告, 其中, 本实施例需要反馈的依据 就是 UE正在接收该 MBMS业务或者感兴趣接收该 MBMS业务。如果需要反馈 MBMS 状态报告, 执行步骤 S306, 否则, 结束。 步骤 S306, 该 UE直接使用已经拥有的上行授权信息发送 MBMS状态报告和该 上行授权信息对应的其他业务数据。
UE确定需要参与计数过程的反馈, 并且 UE的状况为处于连接状态, 正在和基站 进行其他业务数据 (非 MBMS状态报告数据) 的传输, 此时, UE已经拥有了基站为 其分配上行授权信息, 其中, 上行授权信息包含上行资源分配信息、 MCS信息等相关 信息, 该上行授权信息是用来传输 UE的其他上行业务数据的。 本实施例将 MBMS状态报告复用在基站为 UE上行传输其他业务数据的上行资源 中, 并且使用为发送其他业务数据而配置的上行授权信息 (例如 MCS信息等)。 具体 如何把 MBMS状态报告的数据与其他业务数据共同映射到上述上行资源中,参见下述 方式: 在 MAC层,终端把 MBMS状态报告的数据和所述其他业务数据打包为一个 MAC PDU。 例如: 把 MBMS状态报告的数据封装为一个 MAC SDU, 然后与上述其他业务 数据的 MAC SDU封装到一个 MAC PDU中,对于 MAC SDU的封装具体可以参考 LTE 的 MAC层相关协议。再把 MAC层的 MAC PDU输出给物理层,则对应为一个传输块, 然后物理层对这个传输块进行信道编码、 速率匹配、 调制、 映射等处理, 最终使得得 到的处理后的数据的码率和基站为 UE传输其他业务数据而分配的上行授权信息中的 码率信息的要求相同, 然后使用所述上行授权信息中的调制方式信息, 对进一步得到 的数据进行调制处理。总之, UE在物理层对于上述传输块的处理都需要按照上述上行 授权信息的要求进行处理。 其中, 上述上行授权信息是基站为 UE上行传输上述其他 业务数据而配置的, 不是为 UE上行传输 MBMS状态报告的数据而配置的。 步骤 S308, 基站检测接收到的上行数据, 从该上行数据中获取 MBMS状态报告。 在基站下发了计数过程的命令后,基站则认为已经处于了一个计数过程的周期内, 所以基站需要检测 UE的上行数据中是否包含 MBMS状态报告的数据。 因为 UE上行传输 MBMS状态报告的时间点是随机的, 无法事先估计, 所以基站 需要逐个检测。 如果基站可以识别 UE是否具有 MBMS能力, 那么基站则可以仅针对
具有 MBMS能力的 UE的上行数据进行检测,检测该 UE的上行数据中是否包含 MBMS 状态报告的数据。 基站执行的上述检测会在整个计数过程中进行, 直到本次计数过程结束。 如何检 测上行数据中是否包含 MBMS 状态报告, 可以通过 MAC SDU 中的逻辑信道标识 (LCID) 来区分逻辑信道, 然后进一步通过 RRC信息标记判断是该逻辑信道中的哪 一个 RRC 信息, 即可获知该 RRC信息是否为 MBMS状态报告的数据对应的。 本实施例的 UE直接使用已经分配的上行资源传输 MBMS状态报告给基站,基站 在计数过程中检测 UE的上行数据中是否包含 MBMS状态报告, 直到计数过程结束。 解决了 UE发送 MBMS状态报告速度慢的问题, 保证了基站及时地获取到 UE上行发 送的 MBMS状态报告。 并且避免了 UE为发送 MBMS状态报告而申请上行资源的流 程, 提升计数过程的效率, 也节省了系统的资源。 实施例 3 图 4示出了根据本发明实施例的一种 MBMS状态报告的发送系统的结构框图,包 括: 终端 42 (例如实施例 1的终端或实施例 2中的 UE) 和网络侧设备 44 (例如实施 例 2中的基站), 其中, 终端 42包括: 确定模块 422, 设置为确定需要向网络侧设备 44发送 MBMS状态报告; 其中, MBMS状态报告包括下述信息的一个或者多个: 标识终端正在接收或者感 兴趣接收的 MBMS业务的信息; 标识 MBMS状态报告对应的多媒体广播组播业务单 频网 MBSFN区域的信息; 标识 MBMS状态报告对应的计数过程的信息。 发送模块 424, 与确定模块 422相连接, 设置为确定模块 422确定需要发送所述
MBMS状态报告后, 使用网络侧设备 44已为其他业务数据分配的上行授权信息发送 MBMS状态报告和其他业务数据, 其中, 其他业务数据为除 MBMS状态报告之外的 业务数据; 其中, 上行授权信息包括: 为该终端 42分配的传输其他业务数据的上行资源信息 和 MCS等。 当处于连接状态的终端 42需要进行 MBMS状态报告发送时,如果该终端 42已经 拥有了网络侧设备 44分配的上行资源(例如这个终端 42正在和网络侧设备 44进行上 行数据传输, 所以该终端 42拥有网络侧设备 44分配的上行资源, 但是这个上行资源 是用来传输终端 42正在上行的数据的),那么终端 42可以在发送上行其他业务数据的
同时携带 MBMS状态报告,例如: 终端 42使用网络侧设备 44为自己即将上行传输的 其他数据 (非 MBMS状态报告的数据) 配置的上行授权信息中上行资源和 MCS等信 息来上行传输 MBMS状态报告给网络侧设备 44。 网络侧设备 44包括: 检测模块 442, 设置为检测接收到的上行数据中是否包含 MBMS状态报告。 本实施例的网络侧设备 44通过检测模块 442检测到上行数据中包含 MBMS状态 报告后, 提取该 MBMS状态报告, 如果上行数据中没有 MBMS状态报告, 则直接对 上行数据进行相关处理。 优选地, 网络侧设备 44还包括: 计数命令发送模块, 设置为启动 MBMS计数过 程, 向终端 42发送计数命令, 其中, 该计数命令携带有需要进行反馈计数的 MBMS 业务的信息; 相应地, 确定模块 422包括: 接收单元, 设置为接收计数命令发送模块发送的计 数命令; 确定单元, 与接收单元相连, 设置为根据计数命令中的 MBMS业务的信息确 定需要向网络侧设备 44发送 MBMS状态报告。 发送模块 424包括: 封装单元, 设置为在 MAC层对 MBMS状态报告和其他业务 数据进行封装处理; 映射与发送单元, 与封装单元相连, 设置为在物理层使用上行授 权信息中的编码调制信息 MCS要求对封装后的 MBMS状态报告和其他业务数据进行 信道编码、 速率匹配、 调制操作, 将操作后的数据映射到上行授权信息指示的上行资 源中发送。 优选地, 封装单元包括: 第一封装单元, 设置为按照 MAC SDU 的封装格式对
MBMS状态报告进行封装,按照 MAC SDU或者 MAC CE的封装格式对其他业务数据 进行封装; 第二封装单元, 与第一封装单元相连, 设置为将封装后的所述 MBMS状态 报告和所述其他业务数据封装在一个 MAC PDU中。 为了方便网络侧设备 44检测上行数据是否携带 MBMS状态报告, 本发明实施例 的第一封装单元包括: 第一封装子单元, 设置为按照 MAC SDU的封装格式对 MBMS 状态报告进行封装, 其中, 封装后的 MBMS状态报告中携带有 MBMS状态报告对应 的逻辑信道标识; 第二封装子单元, 设置为按照 MAC SDU或者 MAC CE的封装格式 对其他业务数据进行封装, 其中, 封装后的其他业务数据中携带有其他业务数据对应 的逻辑信道标识。

MBMS状态报告进行封装,按照 MAC SDU或者 MAC CE的封装格式对其他业务数据 进行封装; 第二封装单元, 设置为将封装后的 MBMS状态报告和其他业务数据封装在 一个 MAC PDU中。 为了方便网络侧设备检测上行数据是否携带 MBMS状态报告,本发明实施例的第 一封装单元包括:第一封装子单元,设置为按照 MAC SDU的封装格式对 MBMS状态 报告进行封装, 其中, 封装后的 MBMS状态报告中携带有 MBMS状态报告对应的逻 辑信道标识; 第二封装子单元, 设置为按照 MAC SDU或者 MAC CE的封装格式对其 他业务数据进行封装, 其中, 封装后的其他业务数据中携带有其他业务数据对应的逻 辑信道标识。 本实施例的终端直接使用已经分配的上行授权信息传输 MBMS 状态报告给网络 侧设备,解决了终端发送 MBMS状态报告速度慢的问题,保证了网络侧设备及时地获 取到终端上行发送的 MBMS状态报告。 并且避免了终端为发送 MBMS状态报告而申 请上行资源的流程, 提升计数过程的效率, 也节省了系统的资源。 实施例 5 图 6示出了根据本发明实施例的网络侧设备的结构框图, 该网络侧设备包括: 计数命令发送模块 62, 与终端相连, 设置为启动 MBMS的计数过程, 向终端发 送计数命令, 其中, 计数命令携带有需要进行反馈计数的 MBMS业务的信息; 检测模块 64, 与终端相连, 设置为在计数命令发送后, 直到本次计数过程结束, 检测接收到的上行数据中是否包含 MBMS状态报告。
其中, MBMS状态报告包括下述信息的一个或者多个: 标识终端正在接收或者感 兴趣接收的 MBMS业务的信息; 标识 MBMS状态报告对应的多媒体广播组播业务单 频网 MBSFN区域的信息; 标识 MBMS状态报告对应的计数过程的信息。 当处于连接状态的终端需要进行 MBMS状态报告发送时,如果该终端已经拥有了 网络侧设备分配的上行资源 (例如这个终端正在和网络侧设备进行上行数据传输, 所 以该终端拥有网络侧设备分配的上行资源, 但是这个上行资源是用来传输终端正在上 行的数据的), 那么终端可以在发送上行其他业务数据的同时携带 MBMS状态报告, 例如: 终端使用网络侧设备为自己即将上行传输的其他数据(非 MBMS状态报告的数 据) 配置的上行授权信息中上行资源和 MCS等信息来上行传输 MBMS状态报告给网 络侧设备。 该网络侧设备具体可以为基站。 优选地, 检测模块 64包括: 检测单元, 设置为检测接收到的上行数据是否携带有 MBMS状态报告对应的逻辑信道标识; 确定单元, 设置为检测单元检测到上行数据携 带有逻辑信道标识后, 确定上行数据携带有 MBMS状态报告。 本实施例因终端直接使用已经分配的上行资源传输 MBMS 状态报告给该网络侧 设备, 该网络侧设备在计数过程中检测终端的上行数据中是否包含 MBMS状态报告, 直到计数过程结束。解决了终端发送 MBMS状态报告速度慢的问题,保证了网络侧设 备及时地获取到终端上行发送的 MBMS状态报告。 并且避免了终端为发送 MBMS状 态报告而申请上行资源的流程, 提升计数过程的效率, 也节省了系统的资源。 以上实施例中的 UE 已有的上行授权信息中分配的上行资源是参考 UE 之前的
BSR给 UE分配的, 按照 LTE协议 36.321v920中规定的 BSR的方式, 该上行资源存 在较大的冗余, 例如 BSR报告 UE缓存中数据量的大小是一个范围, 而不是准确的数 量,这个范围最小的允许差量为 2个字节, 并且绝大分情况下允许差量为 10个字节以 上, 所以基站参考 BSR为 UE分配上行资源时, 所分配的上行资源中绝大部分情况下 都可以再增加 1~3个字节的数据量, 而不会影响 UE其他业务数据的正常发送。 所以 以上实施例提出了直接使用 UE已经拥有的上行授权信息中的上行资源和 MCS等信息 来发送 MBMS状态报告的数据和所述的其他业务数据。这样, UE在发送 MBMS状态 报告时, 将不需要特意向基站申请上行资源, 加快了 MBMS状态报告的反馈速度, 并 且合理利用了冗余资源, 提高了系统的资源利用率。 显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可以用通用 的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布在多个计算装置所
组成的网络上, 可选地, 它们可以用计算装置可执行的程序代码来实现, 从而, 可以 将它们存储在存储装置中由计算装置来执行, 并且在某些情况下, 可以以不同于此处 的顺序执行所示出或描述的步骤, 或者将它们分别制作成各个集成电路模块, 或者将 它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样, 本发明不限制于任 何特定的硬件和软件结合。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内, 所作的 任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
