Description

指示信息的发送方法、 装置及用户设备 技术领域 本发明涉及通信领域, 具体而言, 涉及一种指示信息的发送方法、 装置及用户设 备 (User Equipment, 简称为 UE)。 背景技术 长期演进 (Long-Term Evolution, 简称为 LTE) 是第三代合作伙伴计划 (Third Generation Partnership Project, 简称为 3GPP) 定义的下一代移动宽带网络标准。 采用 正交频分复用 (Orthogonal Frequency Division Multiplexing, 简称为 OFDM)技术并引 入多输入多输出 (Multiple Input Multiple Output, 简称为 MIMO) 等技术; 同时能够 支持 1.25-20MHZ带宽, 极大提高峰值数据速率和系统容量, 在 20Mhz带宽下支持下 行 100Mbit/s、上行 50Mbit/s的峰值速率; 扁平化的网络结构增强了调度和无线资源控 制效率, 缩短了接续时延。 多媒体广播多播业务(Multimedia Broadcast Multicast Service, 简称为 MBMS, 也 可以称之为 MBMS 业务) 在第三代移动通讯系统已经支持, 架构于第四代移动通讯 LTE系统中增强型多媒体广播 /多播(Enhanced Multimedia Broadcast Multicast Service, 简称为 eMBMS) 业务被业界看作非常有应用场景的一项业务。 其实现方式是具有视 频功能的智能终端通过多播物理信道 (Physical Downlink Multicast Channel, 简称为 PMCH)接收广播 /组播形式的数字音 /视频业务。对 eMBMS的实现和组网方式, 3GPP 协议标准给出了完整的解决方案。 随着 Internet 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, 如视频会议、 电视广播、 视频点播、 广告、 网 上教育、 互动游戏等, 这一方面满足了移动用户多业务的需求, 另一方面也为移动运 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, 3GPP提出了 MBMS, MBMS是一种从一个数据 源向多个目标移动终端传送数据的技术, 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不仅 能够实现纯文本低速率的消息类组播和广播, 而且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 3G的发展提供了更好的业务前景。 接收 MBMS 的 UE可以处于以下两种状态之一: 一种为无线资源控制 (Radio Resource Control, 简称为 RRC) 连接态 (RRC_CO NECTED); 另一种为 RRC空闲 态 (RRC_IDLE)。 根据 UE是否正在接收单播业务, 可以判断正在接收 MBMS的 UE 是处于连接态还是处于空闲态; 当 UE在接收单播业务时, UE处于连接态; 处于空闲 态的 UE没有与网络侧建立 RRC连接, 处于连接态的 UE则与网络侧建立了 RRC连 接。 如果 UE在原小区 (也可以称之为: 当前小区) 有正在接收的 MBMS, 当 UE离 开原小区并驻留到目标小区后(UE如果处于连接模式下, 该 UE可以通过切换过程从 原小区驻留到目标小区, 如果 UE处于空闲模式下, 则该 UE可以通过小区选择 /小区 重选过程从原小区驻留到目标小区, 以上目标小区也可以称之为新小区), UE将读取 广播控制信道(Broadcast Control CHannel,简称为 BCCH)、和多播控制信道(Multicast Control Channel, MCCH) 的消息 (承载在 MBMS控制信道 MCCH上的 MBMS控制 信令称为 MCCH消息), 以获取目标小区中 MBMS的资源配置信息。 如果目标小区 与原小区属于相同的 MBMS单频网络(MBMS over a Single Frequency Network, 简称 为 MBSFN)区域, 即: 目标小区与原小区都属于这个 MBSFN区域(本发明中 MBSFN 区域, BP : MBSFN area, 也简称为 MBSFN), 则 UE在进入目标小区后可以不必读取 MBMS的资源配置信息, 直接使用原小区 (当前小区) 的 MBMS的资源配置信息即 可在目标小区接收 MBMS , MBMS 的内容承载在 MBMS 信道 (Multicast traffic channel, 简称为 MTCH), 实现 MBMS的连续性。 每个 MBMS承载在一条 MTCH信 道上,且每条 MTCH信道上也仅承载一个 MBMS的内容,在本发明中所谓读取 MTCH, 就是指读取承载在 MTCH信道上的 MBMS内容。 如果目标小区和原小区属于不同的 MBSFN区域, 则 UE在进入目标小区后需要读取 MBMS的资源配置信息; 如果在目 标小区中 UE 需要接收的 MBMS 没有发送, 则 UE在进入目标小区后无法读取到 MBMS的资源配置信息, 也无法接收 MBMS。 具有 MBMS能力的 UE的接收状态包括:正在接收 MBMS和感兴趣接收 MBMS。 感兴趣接收 MBMS是指 UE还没有接收 MBMS, 但准备接收 MBMS, 此时, UE可以 监听 MBMS通知消息,根据 MBMS通知消息进一步读取 MCCH消息和 MBMS数据。 在 MBMS开始之前 (session start),广播 /组播业务中心(Broadcast-Multicast Service
Centre, 简称为 BM-SC) 先进行业务通告 (announcement), 通告的目的是向 UE发送 MBMS的简介, 如电子业务导航 (electric service guide, 简称为 ESG), 通告可以通过以 下方式发送: MBMS 承载, 或者交互方式, 如超文本传输协议 (Hypertext Transfer Protocol, 简称为 HTTP), 或者图像传输协议 (Picture Transfer Protocol, 简称为 PTP) push方式,如 SMS, MMS, HTTP push等。通告可以持续到 MBMS会话停止之后。 ESG 的内容承载在用户业务描述 (user service description, 简称为 USD) 上, 用户 (user) 通过读取 USD上承载的 ESG内容, 可以在业务开始之前, 事先获知每个 MBMS (本 发明中 MBMS也可以简称为业务,或者简称为 MBMS)的 MBMS区域(MBMS service area , 简称为 MBMS SA), 在 USD上采用 {TMGI, MBMS SAI list}表示。 其中, 临 时移动组标识 (Temporary Mobile Group Identity, 简称为 TMGI) 对应某个 MBMS, MBMS SAI list对应该业务的业务区域标识(Service Area Identity, 简称为 SAI)列表。 在相关技术中, 一个用户对于某个 MBMS感兴趣并开始读取该业务的过程如下:
UE事先已知包括其感兴趣 MBMS在内的一个或多个 MBMS所对应的 TMGI标 识, 设其感兴趣 MBMS为 TMGI1。 UE驻留在某个小区中, 如果对某个 MBMS感兴 趣 (设其感兴趣 MBMS为 TMGI1 ), 则 UE需要经过以下步骤找到并初始 (开始) 读 取 TMGI1. 首先,读取承载在 BCCH信道上的该小区的系统广播消息( SIB, system information block), 如果该 UE对于某个 MBMS感兴趣, 则该 UE需要读取 SIB13 (编号为 13的 SIB ),在 SIB 13上承载了一条或多条 MCCH的配置信息,每条 MCCH对应一个 MBSFN 区域,通过读取 SIB13,UE可以读取: 1 )每条 MCCH所对应的 MBSFN area ID( MBSFN 区域标识), 2) 每条 MCCH的配置参数 (BP : MCCH配置在哪些无线资源上, 以便 于 UE可以在无线资源上进一步地正确读取 MCCH消息); 然后: UE读取上述每条 MCCH消息,就可以知道其感兴趣的 MBMS是否承载在 某个 MBSFN区域。每条 MCCH消息上承载了其所对应的一个 MBSFN区域所配置的 MBSFN资源以及该 MBSFN区域所有 MBMS的调度信息 (UE可以知道每个 MBMS 具体调度在哪些 MBSFN资源上)。 每个 MBMS与一条 MTCH唯一对应, BP : 每个 MBMS的内容唯一地承载在一条 MTCH上。 具体地说, 通过读取 MCCH消息, UE 可以读取: 1 )其对应的 MBSFN区域的所有 MTCH分别地配置在哪些无线资源上; 2) 其感兴趣的 MBMS进一步地又调度在哪条 MTCH上。比如,其感兴趣的 MBMSTMGI1 配置在某个 MBSFN区域的某个 MTCH上。 最后: UE读取其感兴趣业务所对应的 MTCH (如: MTCH1 )上的内容, 同时 UE 还需要继续读取其感兴趣业务所对应的 MCCH 消息。 一旦 MCCH 消息上关于该 MTCH1的资源配置有变化, UE可以在新的无线资源上继续读取 MTCH1。 总之,为了找到并初始(开始)读取 TMGI1, UE需要读取 SIB13 (可以获得 MCCH 配置参数), 读取 MCCH (可以发现其感兴趣业务承载在哪个 MTCH上), 并读取该承 载有其感兴趣业务的 MTCH。 在移动的过程中,对于空闲态的 UE,一般使用小区选择或重选流程进入目标小区; 对于连接态的 UE, 一般使用小区切换流程进入目标小区。小区选择或重选属于 UE空 闲态下的移动性。 小区选择或重选的目的是确保空闲态 UE驻留在最佳的小区中。 在 无线网络中, 小区选择或重选是必须的一个过程, 主要原因是 UE的移动性、 以及无 线环境的波动性, 由此引起信号强度和干扰水平的波动。 一个 UE驻留在原小区中且在该小区处于正在接收某个感兴趣的 MBMS的状态, 当这个 UE从原小区移动到一个目标小区,并通过小区选择 /重选(或者通过切换流程) 驻留到目标小区, 根据原小区和目标小区是否属于同一个 MBSFN区域, 可以进一步 地将 UE的移动过程分为 UE在同一个 MBSFN区域内的移动 (也称为: Intra-MBSFN area mobility), 或者 UE在不同 MBSFN区域间的移动 (也称为: Inter-MBSFN area mobility )。 当该 UE驻留在某个 MBSFN区域 (设为 MBSFN1 ) 的某个小区, 并可以读取到 其感兴趣的 MBMS之后, UE从原小区, 设为 celll ) 移动到目标小区 (设为 cell2), 此时该 UE将读取目标小区的 SIB13, 以知道目标小区与原小区相比, 是否有 MBSFN 区域的变化, 即: cell2是否属于原先的 MBSFNl , UE是否可以继续接收 TMGI1。 另一方面, 某个小区可能同时处于多个不同 MBSFN区域的覆盖范围内, 即该小 区属于重叠 MBSFN区域的覆盖范围内。 比如: 小区 1处于 {MBSFNl , MBSFN2}的 重叠覆盖范围内, 小区 2处于 { MBSFNl , MBSFN3} , 如图 1所示。 此时, 当一个 UE从小区 1移动到小区 2时候, 对于 MBSFNl而言, UE属于同 一个 MBSFN内的移动, 而对于其他 MBSFN区域则属于不同 MBSFN间的移动。 如 果 UE正在接收的感兴趣的 MBMS承载在 MBSFNl区域上,则 UE在 celll和 cell2都 可以接收到该业务, 但如果 UE正在接收的感兴趣的业务承载在 MBSFN2上, 则 UE 从 celll移动到 cell2上, 则该 UE可能无法在 cell2上继续接收该业务。 在 3GPP相关技术中, 总是假设在 2个相邻的 MBSFN 区域上, 它们所配置的 MBMS不同, 也就是说: 相关技术仅描述了 UE在同一个 MBSFN区域内移动时候的 业务连续性(本发明中业务连续性是指: UE在 2个小区之间移动时候, 该 UE是否可 以接收同一个 MBMS), 但没有研究和提供一个 UE在不同 MBSFN间移动时, 如何提 供 UE接收同一个业务的业务连续性, 尤其没有提供在目标小区的 MBSFN不能承载 该 MBMS的情况下,如何保持业务的连续性的方案。在 UE移动到不能某个承载 MBMS 的小区时, 网络侧往往并不能获知这一情况, 从而网络侧无法保证业务的连续性, 导 致用户侧 MBMS业务接收中断, 降低了用户的体验。 针对相关技术中的上述问题, 目前尚未提出有效的解决方案。 发明内容 针对相关技术中, 在 UE移动到不能某个承载 MBMS的小区时, 网络侧往往并不 能获知这一情况, 从而网络侧无法保证业务的连续性, 导致用户侧 MBMS业务接收中 断的技术问题, 本发明提供一种指示信息的发送方法、 装置及用户设备, 以至少解决 上述技术问题。 根据本发明的一个方面, 提供了一种指示信息的发送方法, 包括: 用户设备 UE 确定自身离开了能够承载预定多媒体广播多播业务 MBMS 的多媒体广播多播业务单 频网络 MBSFN区域, 其中, 所述预定 MBMS为所述 UE在离开所述 MBSFN区域前 正在接收或准备接收的 MBMS;

步骤 S204, 所述 UE向网络侧发送指示信息。 通过该方法, 解决了相关技术中在 UE移动到不能某个承载 MBMS的小区时, 网 络侧往往并不能获知这一情况, 从而网络侧无法保证业务的连续性, 导致用户侧 MBMS业务接收中断的技术问题, 从而可以使得网络侧及时获知 UE离开了能够承载 当前正在接收或准备接收的 MBMS的 MBSFN区域这一情况,便于网络侧及时采取措 施保证 MBMS业务的连续性。 在具体实施过程中, UE可以通过以下方式 (1 ) - (3 ) 中的任何一种确定自身离 开了能够承载所述预定 MBMS的所述 MBSFN区域: ( 1 )所述 UE离开原小区并驻留到目标小区后, 在所述 UE从所述目标小区的系 统广播消息中无法获取到所述预定 MBMS所对应的资源配置信息的情况下, 所述 UE 确定自身离开了能够承载所述预定 MBMS的所述 MBSFN区域。
(2) 在所述 UE监测到当前接收的所述预定 MBMS的信号质量低于信号质量门 槛值的情况下, 所述 UE确定自身离开了能够承载所述预定 MBMS的所述 MBSFN区 域。在该实施方式中,如果 UE认为其正在接收的 MBMS业务的信号质量很差, 比如: 信号质量低于一个预先设置的信号质量门槛值,则 UE判断其离开了该 MBMS业务所 对应的 MBSFN区域, 该 UE向网络侧发送指示信息。
( 3 ) 在所述 UE监测到解码当前接收的所述预定 MBMS时的误码率高于误码率 门槛值的情况下, 所述 UE确定自身离开了能够承载所述预定 MBMS的所述 MBSFN 区域。 在该实施方式中, 如果 UE无法很好地接收 MBMS业务, 比如: UE无法很好 地解码 MBMS业务的内容, 即: 误码率很高, 则 UE判断其离开了该 MBMS业务所 对应的 MBSFN区域, 该 UE向网络侧发送指示信息。 对于 UE离开原小区并驻留到目标小区, 从所述目标小区的系统广播消息中无法 获取到所述预定 MBMS所对应的资源配置信息的情况, 即, 由于 UE离开原小区并驻 留到目标小区导致 UE离开能够承载预定 MBMS的 MBSFN区域的情况, 本发明的一 个优选实施例提供了一种指示信息的发送方法, 图 3 为根据本发明实施例的由于 UE 离开原小区并驻留到目标小区导致 UE离开能够承载预定 MBMS的 MBSFN区域的情 况下的指示信息的发送方法的流程图, 如图 3所示, 该方法包括: 步骤 S302, UE离开原小区并驻留到目标小区; 步骤 S304,当所述 UE从所述目标小区的系统广播消息中无法获取到预定 MBMS 所对应的资源配置信息时, 所述 UE向网络侧发送指示信息, 其中, 所述预定 MBMS 为所述 UE在离开所述原小区之前, 在所述原小区接收或准备接收的 MBMS。 需要说明的是, UE在原小区中可能处于正在接收预定 MBMS的状态 (即背景技 术部分所述的 "正在接收 MBMS ")或准备接收预定 MBMS的状态(即背景技术部分 所述的 "感兴趣接收 MBMS "), 则 UE从原小区驻留到目标小区之后, 对于在原小区 "正在接收"的 MBMS , 可以继续接收该预定 MBMS, 对于在原小区尚未开始接收但 是 "感兴趣接收" 的 MBMS, 可以开始接收该预定 MBMS。 也就是说, 预定 MBMS 可以是正在接收或感兴趣接收的 MBMS。 在原小区, UE可以读取该小区的系统广播消息, 可以知道其属于上述 MBMS业 务所对应的 MB SFN区域, 即: 该 UE在上述 MBMS业务所在的 MBSFN区域内。 此 时: UE可以在原小区接收预定 MBMS。 在驻留到目标小区之后, UE不能从该目标小 区的系统广播消息中获取到上述 MBMS业务所对应的 MBSFN区域相关的消息,可以 知道其不属于上述 MBMS业务所对应的 MBSFN区域, 即: 该 UE在上述 MBMS业 务所在的 MBSFN区域外, 也就是说, 该 UE从上述 MBMS业务所对应的 MBSFN区 域内移动到了该 MBSFN区域外。 以上方法中,如果 UE从目标小区的系统广播消息中无法获取到预定 MBMS所对 应的资源配置信息, 例如, 目标小区的系统广播消息中不含有 UE感兴趣或正在接收 的预定 MBMS所属的 MBSFN所对应的 MCCH配置信息, 则 UE根据在离开原小区 之前从所述原小区的系统广播消息上获取的与所述 MBMS对应的资源配置信息,在所 述目标小区继续接收或开始接收所述预定 MBMS, 并向网络侧发送指示信息以触发所 述网络侧为所述 UE建立用于传递所述预定 MBMS的承载。 考虑到 MBSFN区域中, 多个工作在相同频点的基站可以同时发送内容相同的 MBMS业务,从而可以在叠加作 用下产生宏分集增益,因此,虽然目标小区不属于原小区中承载预定 MBMS的 MBSFN 的覆盖范围, 即: 原小区属于该 MBSFN区域内, 而目标小区属于该 MBSFN区域外, 但是由于该 MBSFN的宏分集增益, 其 MCCH和 MTCH的信号可能仍然很强, 超出 了原小区的范围, 扩展到了目标小区的范围, 也就是说: MCCH和 MTCH的信号可以 超出到 MBSFN区域外, 在宏分集增益的作用下, 此时 UE在目标小区接收或开始接 收的预定 MBMS可能是来源于 MBSFN区域内的多个小区下的业务信号的叠加作用。 借助这一特性, 在目标小区中没有承载该预定 MBMS的 MBSFN的情况下, 仍然采用 原小区的资源配置尽可能地继续接收 MBMS或开始接收感兴趣的 MBMS (对应上述 步骤 S204中, UE在所述目标小区接收所述预定 MBMS )并发送指示信息以触发网络 侧为 UE建立新的承载, 从而 UE通过小区选择 /小区重选过程或者通过切换过程驻留 到目标小区后、 新的承载建立完成之前保持 MBMS的连续性。 因此, 通过以上方法, 解决了相关技术中在 UE移动到不能某个承载 MBMS的小区时, 网络侧往往并不能获 知这一情况, 从而网络侧无法保证业务的连续性, 导致用户侧 MBMS业务接收中断的 技术问题, 从而可以使得网络侧及时获知 UE离开了能够承载当前正在接收或准备接 收的 MBMS的 MBSFN区域这一情况, 便于网络侧及时采取措施保证 MBMS业务的 连续性。 本发明上述各实施例中的网络侧, 可以是基站(例如演进型基站 e B ), 也可以是 核心网网元, 还可以是应用服务器。 当网络侧是指: 核心网网元, UE在目标小区发送 指示信息到 e B并通过该 e B转发到核心网网元; 当网络侧是指: 应用服务器, UE 在目标小区发送指示信息到 e B并通过该 e B转发到核心网网元并进一步地转发到 提供该预定 MBMS业务的应用服务器, 以触发该应用服务器为所述 UE建立用于传递 所述预定 MBMS的承载。 在本发明中, UE发送指示信息到网络侧, 该网络侧的网元 收到该指示信息后, 为该 UE触发建立新承载, 使得该 UE原先正在接收 (或者准备 接收) 的预定 MBMS业务, 可以通过新承载发送到该 UE, 从而使得该 UE可以在网 络侧为其建立的新承载上继续接收预定 MBMS业务。 图 4是根据本发明实施例的 UE向网络侧发送指示信息以触发所述网络侧为所述 UE建立用于传递所述预定 MBMS的承载的过程的详细流程图, 如图 4所示, 在一个 优选的实施方式中, 在上述步骤 S304中, UE向网络侧发送指示信息以触发所述网络 侧为所述 UE建立用于传递所述预定 MBMS的承载的过程可以进一步地包括下述几个 步骤: 步骤 S402, UE判断是否需要向网络侧发送上述指示信息; 步骤 S404, UE决定向网络侧发送该指示信息, 如果 UE处于空闲模式下, 则 UE 首先需要建立 RRC连接, 然后通过专用信令向网络侧发送该指示信息; UE如果处于 连接模式下, 则 UE可以直接通过专用信令向网络侧发送该指示信息; 步骤 S406, 网络侧接收到 UE发送的该指示信息后, 网络侧向该 UE响应确认消 息, 并在确认消息携带新承载的配置信息, 该配置信息用于通知 UE在该新承载上接 收上述预定 MBMS。 步骤 S408, UE接收到网络侧发送的确认消息后, 获得新承载的配置信息; 步骤 S410, UE 根据新承载的配置信息, 建立新承载, 并在该承载上接收预定
MBMS。 优选地, 如果 UE发送了上述指示信息但在预定时间内没有得到网络侧的确认消 息, 则 UE在再次向网络侧发送指示信息。 另外, 还可以在 UE中预先设置一个预定 尝试次数, 如果 UE在发送指示信息的总次数达到了预定尝试次数, 则结束处理。 在实际应用中,步骤 S304中所述 UE从所述目标小区的系统广播消息中无法获取 到所述预定 MBMS所对应的资源配置信息可能包括: 所述 UE从所述目标小区的系统广播消息中无法获取到多播控制信道 MCCH的配 置信息,例如,在现有的标准下, UE从目标小区的系统广播消息中无法获取到 SIB13, 即目标小区上未配置任何 MBSFN区域; 或者, 所述 UE从所述目标小区的系统广播消息中获取到 MCCH的配置信息,但是所述 系统广播消息中包含的所述 MCCH所对应的多媒体广播多播业务单频网络 MBSFN区 域不能承载所述预定 MBMS, 例如, 在现有的标准下, UE从目标小区的系统广播消 息中获取到 smi3, 但是 smi3中所含有的 MCCH所对应的 MBSFN区域并不能承载 该预定 MBMS, 具体地, 该 SIB13中并不含有预定 MBMS在原小区所对应的 MBSFN 区域 (即 UE已离开该 MBSFN区域), 并且该 SIB13所含的 MCCH对应的 MBSFN 区域中, 也没有能够承载该预定 MBMS的 MBSFN区域。 作为一种实施方式, 在所述 UE能够根据在离开所述原小区之前从所述原小区的 系统广播消息中获取的与所述预定 MBMS 对应的资源配置信息读取到所述资源配置 信息对应的 MCCH和 MBMS信道 MTCH的情况下, 所述 UE向所述网络侧发送所述 指示信息以触发所述网络侧为所述 UE建立用于传递所述预定 MBMS的承载,此方法 能够从最大程度上保证预定 MBMS的移动性。 当然, 所述 UE也可以在无法根据所述 原小区提供的与所述 MBMS 对应的资源配置信息读取到所述资源配置信息对应的 MCCH和 MBMS信道 MTCH的情况下 (可能原因是原小区的资源配置信息已改变, 或者 UE距离原 MBSFN区域过远), 向所述网络侧发送所述指示信息以触发所述网络 侧为所述 UE建立用于传递所述预定 MBMS的承载, 此方法能够使得 UE尽快恢复预 定 MBMS的接收。 作为一种优选的实施方式, 在所述网络侧为所述 UE 建立用于传递所述预定 MBMS 的承载之后, 所述 UE 通过所述建立的承载继续接收或开始接收所述预定 MBMS。 在以上各个实施例中, 上述指示信息, 由 UE向网络侧发送, 用于触发网络侧为 UE建立用于传递预定 MBMS的承载。 从具体的内容来讲, 指示信息可以通知网络侧 该 UE已经出了预定 MBMS对应的 MBSFN区域, 以触发所述网络侧为所述 UE建立 用于传递所述预定 MBMS的承载。 需要说明的是, 虽然从系统配置的角度来说, UE 已经离开了预定 MBMS对应的区域, 但是, 由于宏分集增益的效果, 此时 UE可能接 收到预定 MBMS的质量仍然比较好。 基于以上的原因,可以在发出指示信息触发网络侧建立用于传递预定 MBMS的承 载的同时, 借助于宏分集的特性, 所述 UE根据在离开所述原小区之前从所述原小区 的系统广播消息中获取的与所述预定 MBMS对应的资源配置信息,尽可能的在所述目 标小区继续接收或开始接收所述预定 MBMS。 从指示信息的作用上来说,是用于触发网络侧为 UE建立用于传递预定 MBMS的 承载, 但是, 从指示信息携带的内容上来说, 在实际应用中, UE可以发送各类型的指 示信息给网络侧, 以便网络侧能够为 UE建立新的承载, 用以承载该预定 MBMS, 例 如, 所述指示信息可以向所述网络侧报告以下内容 (1 ) - (4) 至少之一: ( 1 ) 用于标记所述 UE离开了能够承载所述预定 MBMS的所述 MBSFN区域的 标志。 此时, 网络侧获知该标志后, 就能够知道所述 UE 离开了能够承载所述预定 MBMS的所述 MBSFN区域, 需要立刻为该 UE建立新的承载, 以便该预定 MBMS能 够通过新承载发送到该 UE上, 从而保持业务的连续性。
(2) 能够承载所述预定 MBMS的所述 MBSFN区域的标识。 指示消息中包括预 定 MBMS业务的 MBMS 区域的标识, 网络侧根据该信息可以知道当前 UE所在的
MBSFN区域不属于这些标识所对应的 MBSFN区域, 即 UE已经离开了能够承载所述 预定 MBMS的所述 MBSFN区域,需要立刻为该 UE建立新的承载,以便该预定 MBMS 能够通过新承载发送到该 UE上, 从而保持业务的连续性。
(3 )所述预定 MBMS的标识信息, 比如: 指示消息中包括: 预定 MBMS业务的 业务标识, 此时, 网络侧可以据此获知 UE 希望继续接收或希望开始接收的预定
MBMS, 由于网络侧知晓各 MBMS所属的 MBSFN区域和各个小区的 MBSFN区域配 置情况, 因此, 网络侧能够知道当前 UE所在的小区并不能为 UE提供该预定 MBMS, 因此, 需要考虑为 UE建立新的承载, 以便该预定 MBMS 能够通过新承载发送到该 UE上, 从而保持业务的连续性。 (4) 建立传递所述预定 MBMS的承载的请求, 比如: 指示消息中包括请求网络 侧为该 UE建立上述承载的请求信息, 此时, 网络侧可以响应该请求为该 UE建立新 的承载,以便该预定 MBMS能够通过新承载发送到该 UE上,从而保持业务的连续性。 需要说明的是, UE可以通过各种类型的指示信息触发网络侧为该 UE建立新的承 载, 指示信息的含义并不限于以上所例举的几种含义, 只要 UE和网络侧对于指示信 息有预先的约定, UE就能够在满足指示条件 (例如, UE从目标小区的系统广播消息 中无法获取到预定 MBMS所对应的资源配置信息) 的情况下成功触发网络侧为该 UE 建立新的承载, 例如, 最简便的方式是 UE和网络侧约定一字段并约定该字段取值的 含义 (如 1表示需要建立新的承载)。 本发明实施例提供了一种指示信息的发送装置, 位于 UE中, 图 5为根据本发明 实施例的指示信息的发送装置的结构框图, 如图 5所示, 该装置包括: 第一确定模块 52,设置为确定所述 UE离开了能够承载预定 MBMS的 MBSFN区 域, 其中, 所述预定 MBMS为所述 UE在离开所述 MBSFN区域前正在接收或准备接 收的 MBMS; 指示模块 54, 连接至第一确定模块 52, 设置为在所述第一确定模块确定所述 UE 离开了能够承载预定 MBMS的 MBSFN区域时, 向网络侧发送指示信息。 优选地, 所述第一确定模块 52设置为: 在所述 UE离开原小区并驻留到目标小区后, 在所述 UE从所述目标小区的系统 广播消息中无法获取到所述预定 MBMS 所对应的资源配置信息的情况下, 确定所述 UE离开了能够承载所述预定 MBMS的所述 MBSFN区域; 或者, 在所述 UE监测到当前接收的所述预定 MBMS的信号质量低于信号质量门槛值的 情况下, 确定所述 UE离开了能够承载所述预定 MBMS的所述 MBSFN区域; 或者, 在所述 UE监测到解码当前接收的所述预定 MBMS时的误码率高于误码率门槛值 的情况下, 确定所述 UE离开了能够承载所述预定 MBMS的所述 MBSFN区域。 在实际应用中, 所述第一确定模块 52设置为在出现以下情况时, 确定所述 UE从 所述目标小区的系统广播消息中无法获取到所述预定 MBMS所对应的资源配置信息: 从所述目标小区的系统广播消息中无法获取到多播控制信道 MCCH的配置信息, 例如, 在现有的标准下, 从目标小区的系统广播消息中无法获取到 SIB13 , 即目标小 区上未配置任何 MBSFN区域; 或者 从所述目标小区的系统广播消息中获取到 MCCH的配置信息,但是所述系统广播 消息中包含的所述 MCCH所对应的 MBSFN区域不能承载所述预定 MBMS,例如,在 现有的标准下, 从目标小区的系统广播消息中无法获取到 smi3, 即目标小区上未配 置任何 MBSFN区域。 图 6是根据本发明实施例的指示信息的发送装置的第一优选结构框图, 如图 6所 示, 该装置还可以包括: 第一接收模块 62, 设置为在所述第一确定模块 52确定所述 UE从所述目标小区的系统广播消息中无法获取到所述预定 MBMS所对应的资源配置 信息时, 根据在离开所述原小区之前从所述原小区的系统广播消息中获取的与所述预 定 MBMS对应的资源配置信息, 继续接收或开始接收所述预定 MBMS。 在一个优选的实施方式中, 所述指示模块 54设置为在所述第一确定模块 52确定 所述 UE从所述目标小区的系统广播消息中无法获取到所述预定 MBMS所对应的资源 配置信息,并且所述第一接收模块 62能够根据在离开所述原小区之前从所述原小区的 系统广播消息中获取的与所述预定 MBMS对应的资源配置信息读取到对应的 MCCH 和 MBMS信道 MTCH的情况下, 向所述网络侧发送所述指示信息。 此方法能够从最 大程度上保证预定 MBMS的移动性。 当然, 所述指示模块 54也可以在无法根据所述 原小区提供的与所述 MBMS 对应的资源配置信息读取到所述资源配置信息对应的 MCCH和 MBMS信道 MTCH的情况下 (可能原因是原小区的资源配置信息已改变, 或者 UE距离原 MBSFN区域过远), 向所述网络侧发送所述指示信息以触发所述网络 侧为所述 UE建立用于传递所述预定 MBMS的承载, 此方式能够使得 UE尽快恢复预 定 MBMS的接收。 在一个优选的实施方式中, 所述第一接收模块 62 还设置为在所述网络侧为所述 UE建立用于传递所述预定 MBMS的承载之后, 通过所述建立的承载继续接收或开始 接收所述预定 MBMS。通过以上方式, UE可以继续接收 MBMS,从而可以保证 MBMS 的连续性。 所述指示模块 54 设置为向所述网络侧发送所述指示信息以触发所述网络侧为所 述 UE建立用于传递所述预定 MBMS的承载。 从指示信息的作用上来说,是用于触发网络侧为 UE建立用于传递预定 MBMS的 承载, 但是, 从指示信息携带的内容上来说, 在实际应用中, UE可以发送各类型的指 示信息给网络侧, 以便网络侧能够为 UE建立新的承载, 用以承载该预定 MBMS, 例 如, 所述指示信息可以向所述网络侧报告以下内容 (1 ) - (4) 至少之一:
( 1 ) 用于标记所述 UE离开了能够承载所述预定 MBMS的所述 MBSFN区域的 标志。 此时, 网络侧获知该标志后, 就能够知道所述 UE 离开了能够承载所述预定 MBMS的所述 MBSFN区域, 需要立刻为该 UE建立新的承载, 以便该预定 MBMS能 够通过新承载发送到该 UE上, 从而保持业务的连续性。
(2) 能够承载所述预定 MBMS的所述 MBSFN区域的标识。 指示消息中包括预 定 MBMS业务的 MBMS 区域的标识, 网络侧根据该信息可以知道当前 UE所在的 MBSFN区域不属于这些标识所对应的 MBSFN区域, 即 UE已经离开了能够承载所述 预定 MBMS的所述 MBSFN区域,需要立刻为该 UE建立新的承载,以便该预定 MBMS 能够通过新承载发送到该 UE上, 从而保持业务的连续性。 (3 )所述预定 MBMS的标识信息, 比如: 指示消息中包括: 预定 MBMS业务的 业务标识, 此时, 网络侧可以据此获知 UE 希望继续接收或希望开始接收的预定 MBMS, 由于网络侧知晓各 MBMS所属的 MBSFN区域和各个小区的 MBSFN区域配 置情况, 因此, 网络侧能够知道当前 UE所在的小区并不能为 UE提供该预定 MBMS, 因此, 需要考虑为 UE建立新的承载, 以便该预定 MBMS 能够通过新承载发送到该 UE上, 从而保持业务的连续性。
(4) 建立传递所述预定 MBMS的承载的请求, 比如: 指示消息中包括请求网络 侧为该 UE建立上述承载的请求信息, 此时, 网络侧可以响应该请求为该 UE建立新 的承载,以便该预定 MBMS能够通过新承载发送到该 UE上,从而保持业务的连续性。 需要说明的是,指示模块 54可以通过各种类型的指示信息触发网络侧为该 UE建 立新的承载,指示信息的含义并不限于以上所例举的几种含义,只要指示模块 54和网 络侧对于指示信息有预先的约定, 指示模块 54就能够在满足指示条件 (例如, UE从 目标小区的系统广播消息中无法获取到预定 MBMS所对应的资源配置信息)的情况下 成功触发网络侧为该 UE建立新的承载, 例如, 最简便的方式是指示模块 54和网络侧 约定一字段并约定该字段取值的含义 (如 1表示需要建立新的承载)。 在所述装置所在的 UE处于空闲模式的情况下,所述指示模块 54可以发起建立无 线资源控制 RRC连接, 并在所述 RRC连接建立成功后, 通过专用信令向所述网络侧 发送所述指示信息; 在所述装置所在的 UE处于连接模式的情况下,所述指示模块 54可以通过专用信 令向所述网络侧发送所述指示信息。 所述网络侧为基站、 核心网网元或应用服务器, 在所述网络侧为所述核心网网元 的情况下,所述指示模块 54设置为在所述目标小区发送所述指示信息到基站, 以触发 所述基站转发所述指示信息到所述核心网网元; 在所述网络侧为所述应用服务器的情 况下,所述指示模块 54设置为在所述目标小区发送所述指示信息到基站, 以触发所述 基站转发所述指示信息到所述核心网网元进而由所述核心网网元转发所述指示信息到 所述应用服务器。 图 7是根据本发明实施例的指示信息的发送装置的第二优选结构框图, 如图 7所 示, 该装置还包括: 第二接收模块 72, 设置为接收所述网络侧响应于所述指示信息所 回复的携带有所述承载的配置信息的确认消息; 承载建立模块 74, 连接至第二接收模 块 72, 设置为根据所述确认消息中携带的所述承载的配置信息, 建立所述承载。 图 8是根据本发明实施例的指示信息的发送装置的第三优选结构框图, 如图 8所 示, 该装置还包括: 控制模块 82, 连接至所述指示模块 54和所述第二接收模块 72, 设置为在所述指示模块 54 向所述网络侧发送所述指示信息后的预定时间内所述第二 接收模块 72未接收到所述网络侧回复的所述确认消息, 并且所述指示模块 54向所述 网络侧发送所述指示信息的次数尚未达到预定尝试次数的情况下, 调度所述指示模块 54再次向所述网络侧发送所述指示信息。 本发明实施例还提供了一种 UE,该 UE可以包括以上所述的指示信息的发送装置, 其内部结构及各部分的功能见以上描述, 在此不再赘述。 本发明实施例还提供了在 UE从原小区重选到目标小区后, 在各种场景下如何保 持 MBMS的连续性的方案,图 9为根据本发明实施例的多媒体广播多播业务的接收方 法的流程图。 如图 9所示, 该方法包括: 步骤 S902, UE接收当前所在原小区所属 MBSFN区域承载的指定 MBMS; 步骤 S904, 在 UE进行小区重选驻留到目标小区后, 在 UE确定目标小区所属 MBSFN区域为与原小区所属 MBSFN区域不同的情况下, UE获取所述目标小区所属 MBSFN区域承载的 MBMS情况; 步骤 S906, UE根据获取的 MBMS情况在目标小区继续接收指定 MBMS。 通过上述处理步骤, 由于 UE 确定目标小区所属 MBSFN 区域与原小区所属 MBSFN区域不同的情况下, 根据获取的目标小区所属 MBSFN区域承载的 MBMS情 况继续接收指定 MBMS业务, 从而可以解决尚无 UE在不同 MBSFN间的不同小区移 动时接收同一业务连续性解决方案的问题, 进而解决在不同小区移动时可能导致的不 能保持同一业务接收连续性的问题, 使得 UE在移出当前 MBSFN区域时仍然可以保 持对同一业务接收的连续性。 上述步骤 S902在具体实施时可以表现为以下实现形式: UE开始接收其感兴趣的 MBMS (即指定 MBMS) 的时候, UE可以知道当前小区上有一个或多个 MBSFN区 域上承载了其感兴趣的 MBMS。 UE读取 (即接收) 其中的一个或多个 MBSFN区域 所承载的相同的其感兴趣的 MBMS。 相应地, 上述步骤 S904和步骤 S906在具体实施时也可以表现为以下实现处理过 程: UE移动并驻留到一个目标小区后, 如果目标小区没有承载其感兴趣的 MBMS, 则 UE采用原小区提供的相关配置参数, 尽可能地读取原先接收其感兴趣的 MBMS, 以保持该业务的业务连续性; UE移动到一个目标小区后,如果目标小区承载其感兴趣 的 MBMS , 则 UE可以知道当前小区上有一个或多个 MBSFN区域上承载了其感兴趣 的 MBMS。 UE 读取其中的一个或多个 MBSFN 区域所承载的相同的其感兴趣的 MBMS; 当 UE可以从多个 MBSFN区域都读取到其感兴趣的 MBMS时候, UE可以 选择其中的一个 MBSFN 区域读取其感兴趣的 MBMS, UE 也可以合并从多个不同 MBSFN区域上获得的 MBMS内容, 以提高接收增益。 合并的方式可以是: 软合并, 或者选择性合并, 也可以是多种合并方法的组合。
UE根据获取的上述 MBMS 情况的不同采用不同的接收方法继续接收上述指定 MBMS, 具体可以包括但不限于以下几种情况: ( 1 ) 在上述 MBMS情况为所述目标小区所属的各个 MBSFN区域均未承载所述 指定 MBMS时, UE按照所述原小区提供的配置参数继续接收指定 MBMS。
(2) 在 MBMS情况为目标小区所属的部分 MBSFN区域承载指定 MBMS时, UE 从部分 MBSFN 区域根据预定策略选择一个或多个 MBSFN 区域继续接收指定 MBMS。 ( 3 )在上述部分 MBSFN区域可以包括原小区所属 MBSFN区域, 也可以包括与 原小区所属 MBSFN区域不同的 MBSFN区域, 对于前一种情况, UE从部分 MBSFN 区域中优先选用原小区所属 MBSFN区域继续接收所述指定 MBMS, 但并不限于此, 例如也可以从部分区域中随机选择一个或多个 MBSFN 区域继续接收所述指定 MBMS。 在 UE从上述部分 MBSFN区域选择多个 MBSFN区域继续接收指定 MBMS后,
UE对从选择的多个 MBSFN区域接收的所述指定 MBMS进行合并处理, 这样可以提 高该指定业务的接收增益。 上述预定策略包括但不限于以下之一: 从部分 MBSFN区域中随机选择一个或多 个 MBSFN区域; 根据部分 MBSFN区域中各个 MBSFN区域承载的 MBMS的信号质 量选择一个或多个 MBSFN区域。 上述原小区所属 MBSFN区域在实际应用时可以为多个, 在这种情况下, 当 UE 可以从多个所述原小区所属 MBSFN 区域中选择一个或多个 MBSFN 区域接收指定 MBMS。 在本实施例中还提供了一种多媒体广播多播业务的接收装置, 该装置位于用户设 备中, 用于实现上述实施例及优选实施方式, 已经进行过说明的不再赘述, 下面对该 装置中涉及到的模块进行说明。 如以下所使用的, 术语 "模块"可以实现预定功能的 软件和 /或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现,但是硬件, 或者软件和硬件的组合的实现也是可能并被构想的。图 10为根据本发明实施例的多媒 体广播多播业务的接收装置的结构框图。 如图 10所示, 该装置包括: 第三接收模块 100,连接至第二确定模块 102和获取模块 104,设置为接收当前所 在原小区所属多媒体广播 /多播业务单频网络 MBSFN区域承载的指定多媒体广播多播 MBMS, 以及根据获取模块 104获取的目标小区所属 MBSFN区域承载的 MBMS情况 继续接收所述指定 MBMS, 其中, 所述目标小区为所述 UE进行小区重选重新驻留的 小区; 第二确定模块 102, 连接至获取模块 104, 设置为在 UE进行小区重选驻留到目标 小区后, 确定所述目标小区所属 MBSFN区域与原小区所属 MBSFN区域不同; 获取模块 104, 设置为在所述第二确定模块 102确定所述目标小区所属 MBSFN 区域为与原小区所属 MBSFN区域不同的情况下, 获取所述目标小区所属 MBSFN区 域承载的 MBMS情况。 通过上述各个模块实现的功能, 使得 UE确定目标小区所属 MBSFN区域与原小 区所属 MBSFN 区域不同的情况下, 根据获取的目标小区所属 MBSFN 区域承载的 MBMS情况继续接收指定 MBMS业务,从而可以解决尚无 UE在不同 MBSFN间的不 同小区移动时接收同一业务连续性解决方案的问题, 进而解决在不同小区移动时可能 导致的不能保持同一业务接收连续性的问题, 使得 UE在移出当前 MBSFN区域时仍 然可以保持对同一业务接收的连续性。 优选地, 上述第三接收模块 100, 还设置为在 MBMS情况为所述目标小区所属的 各个 MBSFN区域均未承载所述指定 MBMS时,按照原小区提供的配置参数继续接收 指定 MBMS。 在本发明的一个优选实施方式中,上述第三接收模块 100,还设置为在上述 MBMS 情况为目标小区所属的部分 MBSFN区域承载指定 MBMS时, 从上述部分 MBSFN区 域根据预定策略选择一个或多个 MBSFN区域继续接收所述指定 MBMS。 上述第三接收模块 100, 还设置为在原小区所属 MBSFN区域为多个的情况下, 从多个所述原小区所属 MB SFN区域中选择一个或多个 MB SFN区域接收指定 MBMS。 为了更好地理解上述实施例, 以下结合具体实施例和相关附图具体说明。 以下实 施例的主要设计思想在于: 当 UE开始尝试接收其感兴趣的 MBMS的时候, 如果 UE在其驻留的当前小区无 法接收其感兴趣的 MBMS, 则该场景不是以下实施例的研究内容, 也就是说, 以下实 施例的应用场景是: 假设 UE总是可以在当前小区所属于的一个或多个 MBSFN区域 中的至少一个 MBSFN区域, 开始接收其感兴趣的 MBMS。 当 UE在当前小区开始接 收其感兴趣 MBMS时候, 可以在一个或多个 MBSFN上都接收到其感兴趣的 MBMS。
UE在原小区开始接收该业务的方法见实施例 1。 当该 UE移动到一个目标小区, UE通过小区重选驻留到该目标小区后, 为了继续 接收在原小区的某个 /某些 MBSFN上承载的其感兴趣的 MBMS, UE在目标小区继续 接收该业务的方法见实施例 2, 为了描述方便, 在本发明中以 UE开始接收其感兴趣 MBMS时候, 总以当前小区仅有一个 MBSFN区域上可以接收该业务为例进行描述。 实施例 1 本实施例, 提供了一种 UE开始接收其感兴趣的 MBMS 的方法, 还提供了一种 UE如何合并多个 MBSFN区域的相同 MBMS内容的方法。 在本实施例中, UE事先已知其感兴趣的 MBMS的 TMGI标识, UE驻留在某个 小区并开始接收其感兴趣的 MBMS。 在本实施例中, 假设: 该小区属于一个或多个 MBSFN (重叠) 区域, 且该 UE可以在其中的至少一个 MBSFN区域读取到其感兴趣 的 MBMS。 如果该 UE可以在多个 MBSFN区域上都接收到其感兴趣的 MBMS, 则 UE可以 选择其中的一个 MBSFN, 也可以选择其中的多个 MBSFN, 在这个 /这些 MBSFN区域 接收其感兴趣的 MBMS。 如果选择其中的一个 MBSFN来接收其感兴趣的 MBMS, 则可以是 UE从这些 MBSFN中随机地选择一个 MBSFN, 也可以是 UE根据这些 MBSFN区域上 MBMS 信号强度和信号质量的好坏来选择一个。 UE从中选择多个 MBSFN,并在这些 MBSFN 上接收的方法与选择一个 MBSFN类似。 总之, UE驻留在一个小区, 且该小区属于一个或多个 MBSFN区域, 该 UE开始 接收其感兴趣的 MBMS的时候, 如果 UE可以同时在多个 MBSFN区域上都接收到感 兴趣的 MBMS, 贝 U: 1 ) UE可以从中选择一个 MBSFN区域接收其感兴趣的 MBMS。 UE可以从中随 机地选择一个 MBSFN, 也可以是 UE根据这些 MBSFN区域上 MBMS信号强度和信 号质量的好坏来选择一个 MBSFN,然后 UE在该 MBSFN区域接收其感兴趣的 MBMS。
2) UE从中选择多个 MBSFN区域接收其感兴趣的 MBMS。 UE可以从中随机地 选择多个 MBSFN, 也可以是 UE根据这些 MBSFN区域上 MBMS信号强度和信号质 量的好坏来选择多个 MBSFN, 然后 UE在这些 MBSFN区域接收其感兴趣的 MBMS。 当 UE可以从多个 MBSFN区域都读取到其感兴趣的 MBMS时候, UE可以合并从多 个不同 MBSFN区域上获得的 MBMS内容, 以提高接收增益。 合并的方式可以是: 软 合并, 或者选择性合并, 也可以是多种合并方法的组合。 实施例 2 本实施例提供了一种在某个小区 (原小区) 正在接收其感兴趣 MBMS的 UE, 通 过小区重选, 驻留到一个目标小区并继续接收该 MBMS的方法(如图 11所示)。本实 施例还提供了一种 UE如何合并多个 MBSFN区域的相同 MBMS内容的方法。 为达到上述目的, 本实施例采用的技术方案如下: 步骤 S1102, UE在原小区的 MBSFN1上接收业务 TMGI1 ; 步骤 S1104, UE小区重选到目标小区; 步骤 S1106, UE读取当前目标小区的 SIB13消息; 步骤 S1108, 比较目标小区与原小区所属 MBSFN区域是否完全相同; 如果是, 则转步骤 S1110, 否则转步骤 S1112; 步骤 S1110, 如果原小区和目标小区都属于完全相同的 MBSFN重叠区域, 则 UE 读取感兴趣 MBMS 的方法与原小区完全相同。 即: 该 UE仍然在相同的一个或多个 MBSFN区域的 MTCH上读取其感兴趣的 MBMS, 至此流程结束。 步骤 S1112, 如果原小区和目标小区属于不完全相同的 MBSFN重叠区域, 判断 目标小区是否未配置 SIB13区域, 即判断目标小区是否不属于任何 MBSFN区域。 如 果是, 转步骤 S1114, 否则转步骤 S1116。 步骤 S1114,如果目标小区上没有配置 SIB13消息,则该 UE移出了所有的 MBSFN 区域, 则 UE尽可能地在原小区所指示的 MCCH配置资源上继续读取 MCCH消息和 继续读取其感兴趣的 MBMS, 至此流程结束。 步骤 S1116, 如果目标小区上 SIB13 消息中, 指明该小区所属于的一个或多个 MBSFN (重叠) 区域中, 是否包括承载正在接收 MBMS的 MBSFN区域, 如果是转 步骤 S1118; 否则转步骤 S1126。 步骤 S1118, UE需要进一步地读取其他区域的 MCCH消息, 转步骤 S1120。 步骤 S1120, 判断新 MBSFN区域是否承载其原先正在读取的 MBMS, 即判断其 它 MBSFN上是否有 TMGI1 , 如果是, 转步骤 S1124, 否则, 转步骤 S1122。 步骤 S1122, 如果目标小区的所有 MBSFN区域上都没有承载其原先正在接收的 MBMS, 则 UE尽可能地在原小区所指示的 MCCH配置资源上继续读取 MCCH消息 和继续读取其感兴趣的 MBMS。 步骤 S1124,如果目标小区的所有 MBSFN区域上有一个或多个 MBSFN区域承载 其原先正在接收的 MBMS, 则 UE 可以在这个 /这些 MBSFN 区域中, 在至少一个 MBSFN区域上读取其原先正在接收的 MBMS。 当目标小区有多个 MBSFN区域都承载了其原先正在接收的 MBMS, 则 UE可以 选择一个, 也可以选择接收多个 MBSFN区域上所承载的其原先正在接收的 MBMS。 UE从多个 MBSFN区域上选择一个 MBSFN区域接收 MBMS的方法,可以是 UE 随机地选择一个 MBSFN, 也可以是 UE根据这些 MBSFN区域上 MBMS信号强度和 信号质量的好坏来选择一个。 UE从中选择多个 MBSFN的方法类似。 同时, UE还可以尽可能地在原小区所指示的 MCCH配置资源上继续读取 MCCH 消息和继续读取其感兴趣的 MBMS。 如果目标小区上 SIB13消息中, 指明该小区所属于的一个或多个 MBSFN (重叠) 区域中,包括承载正在接收 MBMS的 MBSFN区域,则 UE不但可以在原先的 MBSFN 区域上可以继续接收 MBMS,同时 UE还可以通过进一步地读取其他区域的 MCCH消 息, 以确定新 MBSFN区域是否承载其原先正在读取的 MBMS,所以进一步地, 包括: 如果目标小区的所有 MBSFN 区域上都没有承载其原先正在接收的 MBMS, 则 UE在原先的 MBSFN区域上继续接收 MBMS。 如果目标小区的所有 MBSFN区域上,包括与原小区相同的 MBSFN,还有其他一 个或多个 MBSFN区域承载其原先正在接收的 MBMS,则 UE可以在这个 /这些 MBSFN 区域中, 在至少一个 MBSFN区域上读取其原先正在接收的 MBMS。 当目标小区有多个 MBSFN区域(包括与原小区相同的那个 MBSFN)都承载了其 原先正在接收的 MBMS, 则 UE可以选择其中的一个 MBSFN, 也可以选择其中的多 个 MBSFN, 在这个 /这些 MBSFN区域接收其原先正在接收的 MBMS。 如果选择其中的一个 MBSFN来接收其原先正在接收的 MBMS, 则一般情况下, 为了简便起见, UE会在与原小区相同的那个 MBSFN上接收原先正在接收的 MBMS。 但也允许 UE从所有多个 MBSFN区域(包括原先的那个 MBSFN)上选择一个 MBSFN 区域接收 MBMS的方法。 进一步地, 可以是 UE从中随机地选择一个 MBSFN, 也可 以是 UE根据这些 MBSFN区域上 MBMS信号强度和信号质量的好坏来选择一个。
UE也可以从中选择多个 MBSFN, 并在这些 MBSFN上接收, 其方法为: UE从 中选择多个 MBSFN 区域接收其感兴趣的 MBMS。 UE 可以从中随机地选择多个 MBSFN, 也可以是 UE根据这些 MBSFN区域上 MBMS信号强度和信号质量的好坏 来选择多个 MBSFN, 然后 UE在这些 MBSFN区域接收其感兴趣的 MBMS。 当 UE可 以从多个 MBSFN 区域都读取到其感兴趣的 MBMS 时候, UE可以合并从多个不同 MBSFN区域上获得的 MBMS内容, 以提高接收增益。 合并的方式可以是: 软合并, 或者选择性合并, 也可以是多种合并方法的组合。 在本实施例中,为了便于具体实施例的描述方法, UE事先已知其感兴趣的 MBMS 的 TMGI, 设为 TMGI1, UE驻留在某个小区 (设原小区 cell 1 ) 找到和读取 TMGI1 (其感兴趣的 MBMS) 的内容。 具体地说, 1 ) UE预先知道其感兴趣 MBMS被标识 为 TMGI1 ; 2) UE首先读取 SIB13 ; 3 ) 然后 UE找到若干条 MCCH配置信息并读取 这些 MCCH,发现 MCCH1所对应的 MBSFNl上承载了 TMGI1 ; 4)随后, UE在 MTCH 上读取 TMGI1的内容, 且此时 UE仍然监测 SIB13和读取 MCCH1内容。 当该 UE从原小区 (celll ) 通过小区重选到一个目标小区 (设目标小区为 cell2), UE在 cell2读取 SIB13的并获知 cell2上配置了哪个 /哪些 MCCH,从而知道 cell2属于 哪些 MBSFN区域。 会有 3种结果: 该小区 cell2可能无 SIB13, 此时该小区不属于任何 MBSFN区域; 该小区虽然有 SIB13但没有 MCCHl的配置信息,此小区不属于 MBSFNl所覆盖 的区域; 该小区有 SIB13且有 MCCHl的配置信息; 在随后描述的实施例 3,4,5中, 详细地介绍上述三种结果, UE保持业务连续性的 方法。 步骤 S1126, UE读取其他 MBSFN区域的 MCCH消息, 转步骤 S428; 步骤 S1128, 判断其他 MBSFN区域上是否有 TMGI1 , 如果是, 则转步骤 S1132, 否则转步骤 S1130; 步骤 S1130, UE尽可能继续读取 MCCH1和 TMGI1 ; 步骤 S1132, UE在承载了 TMGI1的 MBSFN继续读取业务。 实施例 3 如果出现实施例 2中的结果 1 ), BP: 该小区 cell2无 SIB13, 此时该小区不属于任 何 MBSFN区域, 就是说, 该 UE移出了 MBSFN (包括 MBSFN1 )覆盖区域。 在这种 情况下, 由于 UE无法读取 cell2的 SIB13, 也就无法获取任何 MCCH (包括 MCCH1 ) 的配置信息, 具体如图 12所示。 本实施例中, UE移动出了 MBSFN覆盖区域的场景。 此时, UE从原小区 celll 通过小区重选驻留到目标小区 cell2,该 UE无法读取 SIB13,也就无法获取任何 MCCH 的配置信息。 根据 UE能否在 cell2继续读取 MCCH1和 MTCH1 (虽然 UE无法读取 SIB13从而获取 MCCH的配置信息, 但是, UE采用原配置仍然可能读取到 MCCH1 和 MTCH1的内容), 本实施例再进一步地分为 2种场景。
1-1 ) 在 cell2, UE可以读取到 MCCH1和 MTCH1的内容;
1-2) 在 cell2, UE无法读取到 MCCH1和 MTCH1的内容; 出现结果 1-1 ), 是因为虽然 cell2不属于 MBSFN1 的覆盖区域, 但 MBSFN1 的
MBSFN宏分集的增益, MBSFN1的 MCCH1禾 P MTCH1的信号很强, 超出了 celll的 覆盖区域, 并扩展到了 cell2的覆盖区域内。 出现这种结果还需要 MCCH1的配置参数 不改变(即: SIB 13上关于 MCCH1的配置参数不更新)。由于 UE可以正确读取 MCCH1, 则 UE可以读取 MTCH1 , 可以正确读取 TMGI1的内容, 表现为业务仍然是连续的。 如果出现结果 1-2), 由于 UE无法正确读取 MCCH1 , 则 UE无法读取 TMGI1的 内容, 表现为业务中断。 出现这种结果, 可能是因为 UE距离 MBSFN1的覆盖区域比 较远, UE无法读取和正确接收 MCCH1的内容, 导致 UE因为无法读取 MTCH1 (无 法读取 TMGI1 );也可能是因为 MCCH1的配置参数发生变化,由于 UE无法读取 celll 上 SIB13中对于 MCCHl的配置信息, UE不知道 MCCHl的新配置参数,从而导致该 UE无法读取 MCCH1的内容, 也无法读取 MTCH1/TMGI1内容。 随着 UE从 celll移动并进行小区重选到 cell2,在假设 MCCH1的配置参数不改变 的情况下(SIB13中 MCCH的配置信息一般不会改变), UE 从 celll cell2,并从 cell2 边界区域移动到 cell2中心区域时候, 即 UE如图 13中的 celll的 A点先移动到 B点 (重选到 cell2), 再移动到 C点 (cell2的边界到中心), 一般地会先出现 1-1 ) 再出现 1-2), 在此过程中, UE尽可能地读取 MCCH1和 MTCH1 , 以继续读取其感兴趣的业 务, 保持该业务的业务连续性。 当 UE离开原小区且小区重选到目标小区后, 当 UE读取的目标小区上系统广播 消息中不包括 MCCH1配置参数(也就是: 该 UE感兴趣或正在接收的 MBMS业务所 属于的 MBSFN所对应的 MCCH配置信息), 且该 UE仍然可以读取到 MCCH1 和 MTCH1内容(也就是 UE仍然可以在目标小区继续读取原先的 MCCH和 MTCH),此 时 UE 向网络侧发送指示信息, 该指示信息通知网络侧该 UE 已经移出了某个 /某些 MBFN区域, 和 /或通知网络侧该 UE所感兴趣或正在接收的某个 /某些业务。 这样, 网络侧就可以知道该 UE已经移出了上述 MBSFN区域, 和 /或该 UE将无 法继续获得其感兴趣或正在接收的某个 /某些业务, 需要尽快为该 UE建立新的承载, 以便上述业务可以通过新承载发送到 UE上, 从而保持该业务的业务连续性。 总之, 感兴趣或者正在接收某个 /某些 MBMS业务的 UE, 重选到目标小区后, 如 果在目标小区的系统广播小区上无法读取到上述业务所对应的 MCCH配置信息,一方 面继续尽可能地读取上述业务所对应的 MCCH和 MTCH,—方面通知网络侧该 UE将 无法再获得上述业务了; 网络侧接收到 UE发送的通知信息后, 尽快为该 UE建立新 的承载, 以便上述业务可以通过新承载发送到 UE上, 从而保持该业务的业务连续性。 对于 UE侧, 可以通过以下模块来实现以上功能: 接收模块, 设置为接收目标小区系统广播消息, 且继续接收原 MBSFN上部署的 MBMS业务; 判断模块, 设置为在接收到的目标小区上系统广播消息不包括原 MBSFN区域的 配置参数的情况下, 判断其已经出了原 MBSFN区域; 指示模块, 设置为向网络侧报告其已经离开了原 MBSFN区域; 和 /或向网络侧报 告其希望继续接收的 MBMS业务; 和 /或向网络侧报告其希望和网络侧建立新的承载。 通过以上处理,UE离开了原 MBSFN区域后,可以利用 MBSFN模式发送的 MCCH 和 MTCH信号强的特点, 在原 MBSFN区域外继续接收原先的业务; 另外, UE—方 面在原 MBSFN区域外继续接收原先的业务, 一方面通知网络侧建立新的承载, 从而 能够在最大程度上保证业务连续性。 实施例 4 如果出现结果 2), 该小区虽然有 SIB13但没有 MCCH1的配置信息, 此小区不属 于 MBSFN1所覆盖的区域则 UE仍然无法通过读取 SIB13以获得 MCCH1的配置信息, 但 UE可以通过读取 SIB13获取到其他 MCCH的配置信息, 具体如图 14所示。 本实施例的场景, 对于 MBSFN1 , 也同样属于 UE移出了 MBSFN区域的场景, 与实施例 2不同的是, 在 cell2, UE可以读取其他 MBSFN区域的相关信息, 该 UE既 移出了 MBSFN1 , 同时也进入了其他 MBSFN区域。 此时, 一方面 UE对于 MCCH1 的接收和处理方法同结果场景 1 ),另一方面 UE通过读取 SIB13上其他 MCCH的配置 信息, 并可以读取其他 MCCH的内容, 根据这个 /这些 MCCH的内容, UE会获得不 同的结果: 2-1 ) 其他 MCCH的内容上, 没有其所对应的 MBSFN上承载有 TMGI1,此时 UE 的行为与结果与实施例 3完全相同。
2-2)其他 MCCH的内容上, 有一个或多个 MCCH上承载有 TMGI1 , 即: 有个一 个或多个 MBSFN (不是 MBSFN1 ) 上承载有 TMGI1 , 假设可以表示为: MCCH2所 对应的 MBSFN2上有 TMGI1 , 还可能有 MCCH3/4/..所对应的 MBSFN3/4/...上也同时 承载有 TMGI1。 下面详细介绍此场景下 UE的行为。 在场景 2-2) 中, UE驻留的目标小区 cell2 属于多个其他 MBSFN 区域 (如: MBSFN2/3/4/... , 但不包括 MBSFN1 )。 在 cell2所属于的多个 MBSFN重叠覆盖区域 内, 比如: UE可以从 MBSFN2/3/4/5区域的其中的一个或多个 MBSFN区域上 (如: MBSFN2禾 P/或 MBSFN4)获取 TMGI1的内容。 具体方法为: UE读取 cell2的 SIB13, 如果 cell2属于 MBSFN2/3/4/5重叠覆盖区域, 可以读取这 4个 MBSFN区域所——对 应的 MCCH2/3/4/5的配置信息,然后 UE在每个 MCCH所对应的无线资源上分别读取 每条 MCCH消息,从而知道 MCCH2和 MCCH4上分别了指示了 MTCH1 (对应 TMGI1 ) 的配置和调度信息,最后 UE在 MCCH2和 MCCH4所指示的无线资源上读取到 MTCH1 (即 TMGI内容)。 另一方面, UE在 cell2上也可能读取到 MCCH1 , 即 UE在 cell2上也不但可以读 取其他 MBSFN上所承载的 TMGI1, 也可能读取到承载在 MBSFN1上的 TMGI1。 UE 可以采用合并方法(如: 软合并, 或者选择性合并)合并 UE从不同 MBSFN区域(也 可能还包括 MBSFN1 ) 获得的多个 TMGI1内容, 以提高接收增益。 实施例 5 如果出现结果 3 ), 贝 lj : 该小区有 SIB13且有 MCCH1的配置信息, 说明 UE虽然 从 celll小区重选到 cell2, 但目标小区 cell2仍然与 celll属于同一个 MBSFN1区域, 所以对应 MBSFN1 属于同一个 MBSFN 区域内的切换, 但同时 celll 禾 P cell2 除了 MBSFN1 , 其他 MBSFN区域有所不同, 对于其他 MBSFN区域 (除了 MBSFN1 ) 属 于移出和进入 MBSFN区域。 如图 15所示, 在 cell2, 仍然属于 MBSFN1的覆盖区域, 移出了 MBSFN2的覆盖范围但同时进入了 MBSFN3和 MBSFN4的覆盖区域。
UE小区重选并驻留到 cell2之后, UE读取目标小区 cell2的 SIB13, 可以获得若 干 MCCH的配置信息, UE不但可以知道 cell2仍然属于 MBSFN1 , 而且 UE还可以知 道 cell2属于其他的哪个 /哪些 MBSFN区域,即: cell2的 MBSFN区域与 celll的 MBSFN 区域是否完全相同。 因此本实施例 3可以进一步地包括以下 2种场景。
3-1 ) celll和 cell2属于完全相同的 MBSFN区域, SP: 这 2个小区所属于的所有 MBSFN区域 (MBSFN1/2/3/... ) 完全相同; 对于该场景, UE从原小区 celll重选到目标小区 cell2之后, UE获取 TMGI的方 法在 celll和 cell2完全相同, 属于同一个 MBSFN区域内的移动性; 3-2) celll和 cell2属于不完全相同的 MBSFN区域, 即: 虽然 celll和 cell2都属 于 MBSFN1的覆盖范围, 但同时属于其他至少一个不同的 MBSFN区域, 本实施例中 设: MBSFN4/5/...为不同的 MBSFN区域。 对于场景 3-2), UE从原小区 celll重选到目标小区 cell2之后, 一方面 UE继续接 收 MBSFN1 上承载的 TMGI1 , 同时 UE可以读取其他不同 MBSFN 区域所对应的 MCCH并发现是否承载 TMGI1 , 并会有 2种不同的结果:
3-2-1 ) 其他 MBSFN区域所对应的 MCCH上没有指示有 TMGI1 , 则 UE的获取 TMGI1的行为与场景 3-1完全相同, 即: UE从原小区 celll重选到目标小区 cell2之 后, UE获取 TMGI的方法在 celll和 cell2完全相同, 属于同一个 MBSFN1区域内的 移动性; 3-2-2)其他 MBSFN区域所对应的 MCCH上至少有一条 MCCH上指示有 TMGI1, 则 UE不但读取 MCCH1所对应 MBSFN1 上承载的 TMGIl , UE 也可以读取到其他 MCCH所对应的 MBSFN上承载的 TMGI1。 UE可以采用合并方法 (如: 软合并, 或 者选择性合并) 合并 UE从不同 MBSFN区域 (还包括 MBSFN1 ) 获得的多个 TMGI1 内容, 以提高接收增益。 综上所述, 采用本发明实施例的上述技术方案, UE离开了原 MBSFN区域后, 可 以利用 MBSFN模式发送的 MCCH和 MTCH信号强的特点, 在原 MBSFN区域外继 续接收原先的业务, 可以实现 UE在不同 MBSFN之间移动的时候保持 MBMS的连续 性。 并且, UE—方面在原 MBSFN区域外继续接收原先的业务, 一方面通知网络侧建 立新的承载, 从而在最大程度上保证业务连续性。 在另外一个实施例中, 还提供了一种软件, 该软件用于执行上述实施例及优选实 施方式中描述的技术方案。 在另外一个实施例中, 还提供了一种存储介质, 该存储介质中存储有上述软件, 该存储介质包括但不限于: 光盘、 软盘、 硬盘、 可擦写存储器等。 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 的计算系统来实现, 它们可以集中在单个的计算系统上, 或者分布在多个计算系统所 组成的网络上, 可选地, 它们可以用计算系统可执行的程序代码来实现, 从而, 可以 将它们存储在存储系统中由计算系统来执行, 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。
