Description

一种用户设备及无线网络中保证业务连续接收的方法 技术领域 本发明涉及无线通信技术领域, 尤其涉及一种用户设备及无线网络中 保证业务连续接收的方法。 背景技术
在现有长期演进(Long Term Evolution, 简称: LTE) 无线通信网络中, 为了确定用户设备(User Equipment, 简称: UE) 所在位置的无线信号质量, UE 需要对其服务或驻留小区进行参考信号的测量, 并且考虑到 UE 的移动 性 UE 也需要进行相邻小区进行测量, 这些测量值包括参考信号接收功率 (Reference Signal Received Power, 简称: RSRP) 和参考信号接收质量 (Reference Signal Received Quality, 简称: RSRQ) 等等。 而 RSRP和 RSRQ 是所有测量值中比较重要的测量值。 其中, UE测量到的一个小区的 RSRP越 大, 则 UE从该小区接收到的信号越强; UE测量到的一个小区的 RSRQ越大, 则 UE从该小区接收到的信号质量越高。 当 UE在向远离小区 A的方向移动时, UE测量反馈的小区 A的 RSRP在逐渐变小,而当 UE在向靠近小区 B的方向移动 时, UE测量反馈的小区 B的 RSRP在逐渐变大。 即 UE在移动时, 不断测量反 馈 RRM各测量值, 然后基站通过对应的 RRM测量值, 来发现是否需要改变为 UE提供服务的小区等。
UE通常采用两种方式进行数据的传输, 方式一: UE采用单小区服务 的方式进行数据传输。方式二: UE采用多媒体广播多播业务(Multimedia Broadcast Multicast Service, 简称: MBMS ) 的方式进行数据传输。 其中, 方式二中, 多个小区采用单频网 ( Single Frequency Network, 简称: SFN) 的数据传输方法把数据发送给至少一个 UE。 进一步的, LTE系统在地理 上划分成多个小区, 每个小区都有相应的基站提供服务。 而 MBMS业务 通常是按照 MBMS区域来进行的。 具体的说, 网络中的若干个小区 (通 常是相邻的小区) 可以组成一个 MBMS区域, 同属于一个区域之内的小 区, 都会发送属于这个区域的广播多播业务。 例如, 如果一个区域提供 CCTV1的电视节目, 则这个区域内的所有小区都会提供这个节目。 并且, 这个区域内的所有小区会在相同的时频资源上, 同时发送这个节目的信 号, 这样可以提高 MBMS的传输信号强度, 尤其是提高小区边缘用户的 接收强度。
当 UE在属于不同 MBMS区域的两个基站间移动, 或者在一个属于 MBMS区域的基站和一个属于非 MBMS区域基站间移动, 为了判断是否 进行小区的切换, 现有技术中 UE针对源基站和目标基站的无线信号质量 进行测量, 并基于获得无线信号质量的测量值, 例如上文中的 RSRP和 RSRQ, 判断是否进行小区的切换。 但是采用现有技术对源基站和目标基 站的无线信号质量进行测量的方式进行小区切换的判断, 往往会造成切换 过早, 引发不必要的切换流程, 或切换过晚, 引发业务中断。 发明内容 本发明实施例提供一种用户设备及无线网络中保证业务连续接收的方 法, 用于避免 UE对小区重选或基站发起切换时机的误判, 保证 UE获得 业务数据的接续。

本发明实施例提供的用户设备及无线网络中保证业务连续接收的方 法, 通过用户设备 UE获取至少一个相邻小区的配置信息, UE根据服务小 区的配置信息和至少一个相邻小区的配置信息, 确定包括所述服务小区和至 少一个相邻小区在内的全部小区中, 存在至少两个小区属于相同多媒体广播 多播业务所属的相同区域, 之后, UE在测量参考信号时, 将属于相同多媒 体广播多播业务所属的相同区域的至少两个小区的参考信号测量值进行合 并得到合并测量值; 或者, 将属于相同多媒体广播多播业务所属的相同区域 的至少两个所述小区的参考信号合并, 测量得到合并测量值; 根据合并测 量值决定是否进行小区重选; 或者, 触发向基站发送测量报告, 并向基站 发送测量报告消息, 测量报告消息包含所述合并测量值, 以使基站根据合 并测量值决定是否进行小区切换。 从而在后续的切换判断过程中, UE 或 服务小区的基站考虑到 MBMS 区域整体的信号强度, 避免低估单个小区 无线信号质量, 从而避免了引发不必要的切换流程, 使得切换时机更加合 理, 从而保证了 UE获得的无线信号的质量。 附图说明 为了更清楚地说明本发明实施例或现有技术中的技术方案, 下面将对 实施例或现有技术描述中所需要使用的附图做一简单地介绍, 显而易见 地, 下面描述中的附图是本发明的一些实施例, 对于本领域普通技术人员 来讲, 在不付出创造性劳动性的前提下, 还可以根据这些附图获得其他的 附图。 图 1为小区分布示意图;
图 2为本发明实施例提供的一种用户设备结构示意图; 图 3为本发明实施例提供的一种无线网络中保证业务连续接收的方法 的流程示意图;
图 4为本发明实施例提供的另一种用户设备结构示意图。 具体实施方式 为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本 发明实施例中的附图, 对本发明实施例中的技术方案进行清楚、 完整地描 述, 显然,所描述的实施例是本发明一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有做出创造性劳动前提 下所获得的所有其他实施例, 都属于本发明保护的范围。
图 1为小区分布示意图, 如图 1所示, 以小区 A、 小区 B和小区 C三 个小区为例, 对用户设备 (User Equipment, 简称: UE) 在属于不同多媒 体广播多播业务(Multimedia Broadcast Multicast Service , 简称: MBMS ) 区域的两个基站间移动,或者 UE在一个属于 MBMS区域的基站和一个属 于非 MBMS 区域基站间移动这两种场景中, 在采用现有技术进行无线信 号质量测量时出现的问题进行说明。
若小区 A与小区 B为同一个 MBMS区域内的两个小区, 而小区 C为 一个非 MBMS区域内的小区, 假设用户设备 UE由向小区 B向小区 C移 动, 此时, 根据现有技术的无线信号质量测量机制, UE 需要分别测量小 区八、 小区 B和小区 C的无线信号质量, 之后由 UE根据不同小区的无线 信号质量判断是否进行小区重选; 或者 UE将测量结果发送给服务小区的 基站, 由该基站判断是否进行小区切换。 但是由于 UE处于小区八、 小区 B的边界处,因此单独测量的得到的小区 A的无线信号质量要比小区 C的 无线信号质量差, 基于这样的比较结果, UE 或基站可能会选择切换到小 区( 。 但是根据 MBMS区域的特性可知, 在同一个 MBMS区域内的小区 都会发送属于这个区域的广播多播业务, 从而提高 MBMS 的传输信号强 度, 尤其是提高小区边缘用户的接收强度。 因此, 如果从 MBMS 区域的 角度来看, 如果 UE移动至小区 A, 由 MBMS区域的特性可知, UE的接 收强度要比 UE切换至小区 C好的多, 并且不会引发不必要的切换流程。 显然, 依据现有技术的无线信号质量测量机制, 单独考虑两个小区之间的 无线信号质量差异,很容易低估小区 A的无线信号质量,造成切换的误判, 从而引发不必要的切换流程, 或切换过晚, 引发业务中断。 进一步的, 在 上述场景中, 当 UE切换至小区 C后, 会同时收到小区 A与小区 B的干 扰, 降低了 UE的在小区 C的无线信号质量。
若小区 A与小区 B为 MBMS区域 1内的两个小区, 而小区 C为一个 MBMS区域 2内的小区, 由于不同的 MBMS区域的广播多播业务可能是 相同的, 因此为了接收相同的业务, UE可以从小区 B切换至小区 C, 但 也需要进行相应的切换流程, 根据现有技术的无线信号质量测量机制, 也 会引发上述类似的问题。
因此, 针对上述问题, 本发明各实施例提供一种和用户设备和无线网 络信号质量测量方法, 可以从 MBMS 区域特性的角度进行无线网络信号 质量测量, 避免对小区的网络信号质量测量出现低估或者误判。 下面通过 具体实施例, 对该无线网络信号质量测量方法进行说明。
图 2为本发明实施例提供的一种用户设备结构示意图,如图 2所示, 该 用户设备, 该 UE 可以为包括手机、 平板电脑、 PDA ( Personal Digital Assistant, 个人数字助理) 、 POS (Point of Sales , 销售终端) 、 车载电脑 等用户设备, 该 UE包括: 获取单元 10、 确定单元 11、 合并单元 12、 切换 单元 13。
获取单元 10, 用于获取至少一个相邻小区的配置信息。
确定单元 11, 用于根据服务小区的配置信息和至少一个相邻小区的配 置信息, 确定包括服务小区和至少一个相邻小区在内的全部小区中, 存在至 少两个小区属于相同多媒体广播多播业务区域。
合并单元 12, 用于在测量参考信号时, 将属于相同多媒体广播多播业 务所属的相同区域的至少两个小区的参考信号测量值进行合并得到合并测 量值。
或者, 合并单元 12, 也可以采用将参考信号合并后进行测量的方式得 到合并测量值。
切换单元 13, 用于根据合并测量值决定是否进行小区重选; 或者, 触 发向基站发送测量报告, 并向基站发送测量报告消息, 测量报告消息包含 合并测量值, 以使基站根据合并测量值决定是否进行小区切换。
需要说明的是, 在 UE获得合并测量值之后, 对于处于非连接状态的 UE, 该 UE 根据合并测量值进行小区重选的判断; 对于处于连接状态的 UE,该 UE触发向基站发送测量报告,将测量结果发送给服务小区的基站, 由该基站根据合并测量值决定是否进行小区切换。
继续参照图 1, 以小区 A、 小区 B和小区 C三个小区为例, 基于服务 小区与至少一个相邻小区属于一个 MBMS区域 Areal ,并且至少一个相邻 小区属于另一个 MBMS区域 Area2; 服务小区不属于任何一个 MBMS区 域, 并且至少两个相邻小区属于一个 MBMS区域 Area3 ; 服务小区与至少 一个相邻小区属于一个 MBMS区域 Areal ,并且至少一个相邻小区不属于 任何一个 MBMS区域三种场景, 对本实施例进行说明。
场景一: 若小区 A与小区 B为属于 Areal的两个小区, 而小区 C为 属于 Area2的小区, 其中小区 A为 UE当前的服务小区 (或驻留小区) , 由于不同的 MBMS区域的多媒体广播多播业务可能是相同的, 因此当 UE 获知当前接收或者准备接收的 Areal中的多媒体广播多播业务(即 UE感 兴趣的多媒体广播多播业务)在相邻区域 Area2 中也正在发送,则 UE 可 以将 Areal的参考信号测量值则 UE的合并单元 12将 Areal小区 A的参 考信号测量值与小区 B的参考信号测量值进行合并获得合并测量值 a, 即 Areal 的信号质量测量值, 随后切换单元 13根据该合并测量值 a决定是 否进行小区重选, 该过程也可以称为区域重选, 即 UE 从 Areal 的小区 中接收业务重新选择到从 Area2 的小区中接收业务, 或者, 切换单元 13 向基站发送测量报告消息, 该报告中包含合并测量值 a, 以使基站根据该 合并测量值 a决定是否进行小区切换, 如果基站决定进行小区切换, 则基 站发送小区切换命令给 UE;该过程也可以称为区域切换, g卩 UE 从 Areal 的小区中接收业务切换到从 Area2 的小区中接收业务, 如果基站决定进 行区域切换, 则基站发送区域切换命令给 UE, 该消息中至少包含 UE 所 要切换到的目标区域的标识信息, 比如: Area标识、 Area所在频率标识。 具体的, 一种可行的实现方式为: UE 根据预先配置的阈值, 决定是否要 发起小区重选、 区域重选, 或小区切换、 区域切换, 该预先配置的阈值, 可以是基站通过专用消息通知给 UE, 也可以通过广播消息广播给 UE, 还可以是 UE 内部实现的一个配置阈值;当合并测量值 a达到预先配置的 阈值时, 则切换单元 13根据该合并测量值 a决定不进行小区重选、 或不 进行区域重选, 例如当合并测量值 a上升到、 或超过预先配置的阈值, 说 明此时 Areal的无线网络信号质量符合 UE接收业务的要求, 则 UE依然 通过 Areal接收或准备接收多媒体广播多播业务, 而不会选择 Area2中的 小区 C或小区 D作为接收、 准备接收业务的小区, 或不会选择 Area2 作 为接收、 准备接收业务的区域; 或者, 当合并测量值 a达到预先配置的阈 值, 触发切换单元 13 向基站发送上述测量报告消息。 另一种可行的实现 方式为: 当合并测量值 a低于或下降到预先配置的阈值, 则切换单元 13 根据该合并测量值 a决定进行小区重选、 或进行区域重选; 或者, 当合并 测量值 a低于或下降到预先配置的阈值, 则触发切换单元 13 向基站发送 上述测量报告消息。 下文会对 UE如何配置阈值进行详细说明。
进一步的, 若 Area2中除了小区 C, 还包含小区 D , 并且属于 Area2 的小区 C和小区 D都具有该 UE当前接收或者准备接收的多媒体广播多播 业务(即 UE感兴趣的多媒体广播多播业务) 时, 则 UE的合并单元 12将 Area2中小区 C的参考信号测量值与小区 D的参考信号测量值进行合并获 得合并测量值 b。此时, UE同时得到 Areal的合并测量值 a与 Area2的合 并测量值 b,切换单元 13根据合并测量值 a与合并测量值 b决定是否进行 小区重选、 或区域重选; 或者, 切换单元 13依据合并测量值 a与合并测 量值 b决定是否触发测量报告消息, 如果决定触发测量报告消息, 则向基 站发送测量报告消息消息, 该测量报告消息消息中包含合并测量值 a与合 并测量值 b, 以使基站根据合并测量值 a与合并测量值 b决定是否进行小 区切换, 如果基站决定进行小区切换, 则基站发送小区切换命令给 UE; 该过程也可以称为区域切换, 即 UE 从 Areal 的小区中接收业务切换到 从 Area2 的小区中接收业务, 如果基站决定进行区域切换, 则基站发送 区域切换命令给 UE,该消息中至少包含 UE 所要切换到的目标区域的标 识信息, 比如: Area标识、 Area所在频率标识。 具体的, 一种可行的实 现方式为: 切换单元 13将合并测量值 a与合并测量值 b进行比较, 进一 步的, UE可以将合并测量值 a与合并测量值 b直接进行比较, 或者, 也 可以将合并测量值 a与合并测量值 b的差值与预设阈值进行比较, 比如: 合并测量值 a 与 b 的差是否达到、 或超过预设阈值; 若合并测量值 a优 于合并测量值 b, 由于 UE当前的服务小区为小区 A, 因此, UE依然通过 Areal接收或准备接收多媒体广播多播业务, 而不会选择 Area2中的小区 C或小区 D; 若合并测量值 b优于合并测量值 a, 则选择 Area2接收或准 备接收多媒体广播多播业务, 具体的, UE将选择 Area2中的小区 C或小 区 D作为服务小区; 另一种可行的实现方式: 切换单元 13向基站发送测 量报告消息, 该测量报告消息包含合并测量值 a与合并测量值 b, 该基站 将合并测量值 a与合并测量值 b进行比较, 具体的, UE可以将合并测量 值 a与合并测量值 b直接进行比较, 或者, 也可以将合并测量值 a与合并 测量值 b的差值与预设阈值进行比较,若合并测量值 a优于合并测量值 b, 由于 UE当前的服务小区为小区 A, 因此, 基站指示 UE不进行切换, 并 依然通过 Areal接收或准备接收多媒体广播多播业务,而不会切换至 Area2 中的小区 C或小区 D;若合并测量值 b优于合并测量值 a,则基站指示 UE 切换至 Area2 接收或准备接收多媒体广播多播业务, 具体的, 基站指示 UE切换至 Area2中的小区 C或小区 D。
需要说明的是, 对于场景一, UE 或者服务小区的基站需要预先获知 两个 MBMS区域具有 UE当前接收或准备接收的多媒体广播多播业务;如 果某一个 MBMS区域中没有 UE正在接收或准备接收的多媒体广播多播业 务, 则 UE不能选择该 MBMS区域接收多媒体广播多播业务, 即在进行区 域选择的测量时, 只考虑包含 UE正在接收或准备接收的多媒体广播多播 业务区域, 或者在测量报告消息中包含 UE正在接收或准备接收的多媒体 广播多播业务区域的测量结果, 不包含没有发送 UE正在接收或准备接收 的多媒体广播多播业务区域的测量结果, 基站不能指示 UE 切换至该 MBMS 区域, 否则业务会中断。 但是, 对于 UE从 MBMS区域中的一个 小区向单播小区切换时, 则没有该限制, 因为单播业务是为 UE建立的专 用传输资源, 因此不受该限制。
场景二: 小区 A不属于任何一个 MBMS区域 (例如, 小区 A为单播 小区) , 小区 B与小区 C为 Area3内的两个小区, 其中小区 A为 UE当前 的服务小区 (或驻留小区) , 当 UE当前接收或者准备接收的小区 A中的 多媒体广播多播业务 (即 UE感兴趣的多媒体广播多播业务) 在相邻小区 Area3中也正在发送,则 UE的合并单元 12将 Area3中小区 B的参考信号 测量值与小区 C的参考信号测量值进行合并获得合并测量值 c, 即 Area3 的信号质量测量值, 随后切换单元 13根据该合并测量值 c决定是否进行 小区重选、 或区域重选, 或者, 切换单元 13根绝该合并测量值 c 决定是 否触发测量报告, 并向基站发送测量报告消息, 该测量报告消息中包含合 并测量值 c, 以使基站根据该合并测量值 c决定是否进行小区切换。 具体 的, 一种可行的实现方式为: UE 根据预先配置的阈值, 决定是否要发起 小区重选、 区域重选, 或小区切换、 区域切换, 该预先配置的阈值, 可以 是基站通过专用消息通知给 UE, 也可以通过广播消息广播给 UE, 还可 以是 UE 内部实现的一个配置阈值; 当合并测量值 c 达到预先配置的阈 值, 则切换单元 13根据该合并测量值 c决定是否进行小区重选、 或区域 重选, 例如当合并测量值 c达到预先配置的阈值, 说明此时 Area3的无线 网络信号质量符合 UE 接收广播多播业务数据的要求, 则 UE 选择通过 Area3接收或准备接收多媒体广播多播业务; 或者, 切换单元 13触发测量 报告, 并向基站发送上述测量报告消息。 另一种可行的实现方式为: 当合 并测量值 c低于 /或下降到预先配置的阈值, 则切换单元 13根据该合并测 量值 c决定是否进行小区重选、 或区域重选; 或者, 当合并测量值 c低于 /或下降到预先配置的阈值时,切换单元 13触发向基站发送上述测量报告。
场景三: 小区 A与小区 B为属于 Areal的两个小区, 小区 C不属于 任何一个 MBMS区域 (例如, 小区 C为单播小区) , UE 正在接收、 或 准备接收 Area l中广播的业务 X, 并且 UE 确定在小区 C 中支持广播多 播业务 X 的传输, 则 UE的合并单元 12将属于 Areal中小区 A的参考信 号测量值与小区 B 的参考信号测量值进行合并获得合并测量值 a, 即 Areal 的信号质量测量值, 随后切换单元 13根据该合并测量值 a决定是 否进行小区重选, 或者, 切换单元 13 决定是否触发测量报告, 如果切换 单元 13 决定向基站发送测量报告消息, 该测量报告消息中包含合并测量 值 a, 以使基站根据该合并测量值 a决定是否进行小区切换。 具体的, 一 种可行的实现方式为: UE根据预先配置的阈值, 将合并测量值 a与预先 配置的阈值比较, 切换单元 13根据该合并测量值 a与预先配置的阈值比 较结果决定是否进行小区重选、 或区域重选, 例如当合并测量值 a达到、 或超过预先配置的阈值, 说明此时 Areal的无线网络信号质量符合 UE的 要求, 则 UE依然通过 Area3接收或准备接收多媒体广播多播业务, 不需 要选择小区 C作为服务小区;或者,当合并测量值 a达到预先配置的阈值, 触发切换单元 13 向基站发送上述测量报告消息。 另一种可行的实现方式 为: 当合并测量值 a低于、 或下降到预先配置的阈值, 则切换单元 13根 据该合并测量值 a决定是否进行小区重选; 或者, 当合并测量值 a低于、 或下降到预先配置的阈值, 触发切换单元 13 向基站发送上述测量报告消 息。 进一步的, 对于场景二和场景三, 另一种可行的实现方式为: UE 将 具有相同多媒体广播多播业务所属的相同区域的合并测量值与不属于任何 多媒体广播多播业务所属的区域的其他小区的参考信号测量值进行比较, 从而决定是否进行小区重选、 或进行区域重选; 或者, UE 将包含合并测 量值和参考信号测量值的测量报告消息发送给基站, 基站将合并测量值与 其他小区的参考信号测量值进行比较, 决定是否进行小区切换, 该实现方 式将在下文中进行详细说明。
对于场景一、 二、 三, 在 UE 进行区域信号质量测量之前, 基站可 以通过专用消息、 或系统广播发送区域测量配置消息给 UE, 该测量配置 消息中包含一下任意一种或任意组合的参数: 待测量的区域标识信息; 待 测量区域信号质量类型, 比如: 参考信号接收功率 (Reference Signal Receiving Power, 简称: RSRP)和 /或参考信号接收质量( Reference Signal Receiving Quality , 简称: RSRQ) 。
进一步的, 还可以包含: 待测量区域的频点信息; 待测量区域所对应 的小区标识信息; 需要删除的待测量的区域标识信息; 需要更新的待测量 的区域标识信息。
需要说明的是, 本发明各个实施例中涉及的 MBMS 区域, 其最小的 单元为一个小区, 即一个 MBMS 区域包含至少一个小区。 另外, 本实施 例中以三个小区进行说明, 对于 UE在移动过程中获取到多少个相邻小区 的配置信息根据实际的小区分布场景来决定, 本实施例不做限定, 只要确定 多个小区属于同一个 MBMS区域, 则将属于同一 MBMS区域的全部小区 的参考信号测量值进行合并, 再根据不同 MBMS 区域的合并测量值, 或 者根据 MBMS区域的合并测量值与非 MBMS区域的小区的参考信号测量 值由 UE决定是否进行小区重选, 或者由基站决定是否进行小区切换。
本实施例提供的用户设备,通过获取单元获取至少一个相邻小区的配置 信息, 确定单元根据服务小区的配置信息和至少一个相邻小区的配置信息, 确定包括所述服务小区和至少一个相邻小区在内的全部小区中, 存在至少两 个小区属于相同多媒体广播多播业务所属的相同区域, 之后, 合并单元在测 量参考信号时,将属于相同多媒体广播多播业务所属的相同区域的至少两个 小区的参考信号测量值进行合并得到合并测量值; 或者, 将属于相同多媒 体广播多播业务所属的相同区域的至少两个所述小区的参考信号合并, 测量 得到合并测量值;切换单元根据合并测量值决定是否进行小区重选;或者, 触发向基站发送测量报告, 并向基站发送测量报告消息, 测量报告消息包 含所述合并测量值, 以使基站根据合并测量值决定是否进行小区切换。 从 而在后续的切换判断过程中, UE或服务小区的基站考虑到 MBMS区域整 体的信号强度, 避免低估单个小区无线信号质量, 从而避免了引发不必要 的切换流程, 使得切换时机更加合理, 从而保证了 UE获得的无线信号的 质量。
需要说明的是, 在 LTE 无线通信网络中, 为了确定 UE 所在位置的 无线信号质量, UE 需要对其服务或驻留小区进行参考信号的测量, 考虑 到 UE 的移动性 UE 也需要进行相邻小区进行测量, 这些测量量包括参 考信号接收功率 (Reference Signal Received Power, 简称: RSRP) 和参考 信号接收质量 (Reference Signal Received Quality, 简称: RSRQ) 等等。 而 RSRP和 RSRQ是所有测量量中比较重要的测量量。
其中, RSRP为参考信号接收功率,定义为测量带宽内承载所有测量 RSRP 用的 CRS端口对应资源单元(Resource Element, 简称: RE)上对应小区特定 参考信号(Cell-specific Reference Signal , 简称: CRS) 的接收功率的线性平 均值。针对 RSRP的测量, UE需要使用 CRS端口 0进行测量。 当 UE能够可靠检 测到 CRS端口 1时, UE可以在使用 CRS端口 0的同时使用端口 1和端口 0—起来 确定 RSRP。 RSRQ为 NxRSRP/(E-UTRA carrier RSSI), 其中 N为 E-UTRA系统 中用于测量 E-UTRA网络承载接收信号强度指示 ( E-UTRA carrier Received Signal Strength Indicator) 测量带宽的资源块 (Resource Block , 简称: RB ) 个数。 其中分子和分母需要对应相同的资源数量。 E-UTRA carrier RSSI为在 规定的测量带宽内 N个 RB上测量到的承载 CRS参考信号天线端口 0的 OFDM 符号上的总接收功率的线性平均值, 包括服务小区的共道干扰、 非服务小区 产生的干扰, 邻道干扰, 热噪声等等。 如果高层信令指示了用于测量 RSRQ 的特定的子帧, 那么 RSSI将从对应子帧的所有 OFDM符号上测量。
UE测量到的一个小区的 RSRP越大, 则 UE从该小区接收到的信号越强; UE测量到的一个小区的 RSRQ越大, 则 UE从该小区接收到的信号质量越高。
UE进行 RRM无线资源管理 (Radio Resource Management) 的测量(包括 RSRP、 RSRQ、 RSSI的测量) , 是在测量带宽内, 一个时间范围内多次测量 后求线性平均来得到对应的 RRM测量值。 如在 200ms内测量 5次 RSRP测量值 后通过线性平均, 得到对应的 RSRP测量值。
其中, RRM测量值主要用于 UE的移动性管理等。如 RSRP代表一个 小区到 UE的参考信号的平均接收功率, 当 UE在向远离小区 B的方向移 动时, UE测量反馈的小区 B的 RSRP在逐渐变小, 而当 UE在向靠近小 区 A的方向移动时, UE测量反馈的小区 A的 RSRP在逐渐变大。 即 UE 在移动时, 不断测量反馈 RRM各测量值, 然后基站通过对应的 RRM测 量值, 来发现是否需要改变为 UE提供服务的小区等。
进一步的, 由于 UE决定重选小区或者基站指示 UE切换小区后, 若 目标小区为单播传输小区, 则需要 UE 当前接收或准备接收的多媒体广播 多播业务是否支持单播传输, 因此, 进一步的, 获取单元 10, 还用于获取 UE当前接收或准备接收的多媒体广播多播业务的单播传输指示信息。 该单 播传输指示信息用以指示该业务是否支持单播传输指示信息, 若单播传输指 示信息指示该业务支持单播传输, 则在上述测量结果满足小区重选条件下, 则切换单元 13决定进行小区重选。
或者,上述 UE当前接收或准备接收的多媒体广播多播业务的单播传输 指示信息也可以由基站获取, 当基站接收到 UE发送的测量报告消息后, 若 根据测量报告消息中包含的测量结果判断满足小区切换的条件并且目标 小区为单播传输小区, 则此时基站根据该业务的单播传输指示信息判断该 业务是否支持单播传输, 若单播传输指示信息指示该业务支持单播传输, 则 基站指示 UE进行小区切换。
需要说明的是, 对于上述两种情况, 若单播传输指示信息指示该业务不 支持单播传输, 则 UE不会选择该目标小区作为服务小区; 基站不会指示 UE 切换至该目标小区。
进一步的, 对于服务小区不属于任何一个 MBMS 区域, 并且至少两 个相邻小区属于一个 MBMS区域 Area3;服务小区与至少一个相邻小区属 于一个 MBMS区域 Areal,并且至少一个相邻小区不属于任何一个 MBMS 区域的两种场景, 除了采用上述 UE根据合并测量值决定是否进行小区重 选或者基站根据合并测量值决定是否进行小区切换的方式之外, 还可以采 用如下实现方式:
切换单元 13,具体用于将合并测量值与至少一个其他小区的参考信号 测量值进行比较, 决定是否进行小区重选; 或者,
切换单元 13 向基站发送的测量报告消息除了包含合并测量值外, 还 包含至少一个其他小区的参考信号测量值, 以使基站将合并测量值与至少 一个其他小区的参考信号测量值进行比较, 决定是否进行小区切换。
其中, 其他小区指包括服务小区和至少一个相邻小区在内的全部小区中 不属于任何多媒体广播多播业务所属的区域的小区。
下面继续采用上文中所述场景二和场景三对根据合并测量值与参考信 号测量值比较, 来决定是否进行小区重选或是否进行小区切换的方案说 明:
场景二: 小区 A不属于任何一个 MBMS区域 (例如, 小区 A为单播 小区) , 小区 C与小区 B为 Area3内的两个小区, 其中小区 A为 UE当前 的服务小区, 当 UE获知属于 Area3的小区 B和小区 C具有该 UE当前接 收或者准备接收的多媒体广播多播业务 (即 UE感兴趣的多媒体广播多播 业务) 时, 则 UE的合并单元 12将 Area3中小区 B的参考信号测量值与 小区 C的参考信号测量值进行合并获得合并测量值 c, 并且, UE获得小 区 A的参考信号测量值, 随后切换单元 13根据该合并测量值 c与小区 A 的参考信号测量值决定是否进行小区重选, 或者, 切换单元 13 向基站发 送测量报告消息,该测量报告消息中包含合并测量值 c和小区 A的参考信 号测量值, 以使基站根据该合并测量值 c和小区 A的参考信号测量值决定 是否进行小区切换。 具体的, 一种可行的实现方式为: UE将合并测量值 c 和小区 A的参考信号测量值进行比较, 进一步的, UE可以将合并测量值 c与小区 A的参考信号测量值直接进行比较, 或者, 也可以将合并测量值 c与小区 A的参考信号测量值的差值与预设阈值进行比较。 当合并测量值 c优于小区 A的参考信号测量值时, 说明此时 Area3的无线网络信号质量 符合 UE的要求, 则 UE选择通过 Area3接收或准备接收多媒体广播多播 业务, 若小区 A的参考信号测量值优于合并测量值 c时, 说明此时小区 A 的无线网络信号质量符合 UE的要求, 则 UE依然通过小区 A接收或准备 接收多媒体广播多播业务,不选择 Area3中的小区 B或小区 C作为服务小 区。另一种可行的实现方式为: 切换单元 13向基站发送包含合并测量值 c 和小区 A的参考信号测量值的测量报告消息,基站将合并测量值 c和小区 A的参考信号测量值进行比较, 决定是否进行小区切换, 其具体的比较过 程与 UE类似, 此处不再赘述, 最后基站根据比较结果指示 UE进行小区 切换, 或者指示 UE不进行小区切换。
场景三: 小区 A与小区 B为 Areal 内的两个小区, 小区 C不属于任 何一个 MBMS区域 (例如, 小区 C为单播小区) , 其中小区 A为 UE当 前的服务小区, 当 UE获知属于 Areal的小区 A和小区 B具有该 UE当前 接收或者准备接收的多媒体广播多播业务 (即 UE感兴趣的多媒体广播多 播业务) 时, 则 UE的合并单元 12将 Areal中小区 A的参考信号测量值 与小区 B的参考信号测量值进行合并获得合并测量值 a, 并且, UE的获 取模块 10获取小区 C的参考信号测量值,随后切换单元 13根据该合并测 量值 a和小区 C的参考信号测量值决定是否进行小区重选, 或者, 切换单 元 13 向基站发送测量报告消息, 该测量报告消息中包含合并测量值 a和 小区 C的参考信号测量值,以使基站根据该合并测量值 a和小区 C的参考 信号测量值决定是否进行小区切换。具体的,一种可行的实现方式为: UE 将合并测量值 a和小区 C的参考信号测量值进行比较,决定是否进行小区 重选。 其比较方式与场景二中 UE的比较方式类似, 此处不再赘述。 另一 种可行的实现方式为:切换单元 13向基站发送包含合并测量值 a和小区 C 的参考信号测量值的测量报告消息,基站将合并测量值 a和小区 C的参考 信号测量值进行比较, 决定是否进行小区切换, 其具体的比较过程与 UE 类似, 此处不再赘述, 最后基站根据比较结果指示 UE进行小区切换, 或 者指示 UE不进行小区切换。
需要说明的是, 上述三个场景仅对具有三个小区的情况进行了说明, 当有多个 MBMS区域中包含至少两个小区, 并且每个 MBMS区域都具有 该 UE当前接收或者准备接收的多媒体广播多播业务 (即 UE感兴趣的多 媒体广播多播业务) 时, 则分别合并每个 MBMS 区域中的参考信号测量 值, 获得每个 MBMS区域的合并测量值, UE在将多个合并测量值进行比 较, 或者与预先配置的阈值进行比较, 其具体的比较方式与上文的比较方 式类似, 从而由 UE决定是否进行小区重选; 或者, 触发 UE向基站发送 测量报告消息, 以使基站决定是否进行小区切换。
进一步的,获取单元 10可以通过两种可行的实现方式来获取配置信息: 实现方式 1 :
获取单元 10,具体用于接收源基站发送的至少一个相邻小区的广播多播 信号测量配置消息, 相邻小区的广播多播信号测量配置消息包含相邻小区 的配置信息。
实现方式 2:
获取单元 10, 具体用于读取源基站发送的广播, 广播包含相邻小区的配 置信息。
对于实现方式 1和实现方式 2, 其中, 相邻小区的配置信息具体包含相 邻小区的多媒体广播多播业务所属区域对应的区域标识和相邻小区的频率 信息, 其中, 相邻小区的频率信息包含相邻小区所在的频率和 /或频率层标 识信息。
根据相邻小区的多媒体广播多播业务所属区域对应的区域标识和相邻 小区的频率信息, 获知测量目标的频率层和 /或广播多播区域对应一个小 区, 则 UE 仅测量该小区的广播多播参考信号, 并将该小区的参考信号测 量值作为目标区域的频率层和 /或广播多播区域的广播多播参考信号的参 考信号测量值; 一个频率层标识信息可以对应一个或多个广播多播小区标识 信息; 一个广播多播区域可以对应一个或多个广播多播小区标识信息;
根据相邻小区的多媒体广播多播业务所属区域对应的区域标识和相邻 小区的频率信息, 获知测量目标的频率层和 /或广播多播区域对应多个小 区, 则 UE将属于目标的频率层和、 或广播多播区域对应多个小区的广播 多播参考信号合并测量;或分别对属于目标的频率层和 /或广播多播区域对 应多个小区的广播多播参考信号进行单独测量, 并将测量结果合并为合并 测量值, 合并测量值作为目标的频率层和、 或广播多播区域的广播多播参 考信号的测量结果; UE 也可以通过对相邻小区的测量, 发现属于所要测 量目标的频率层和 /或广播多播区域所包含的小区。
进一步的, 相邻小区的配置信息还包含阈值配置信息和 /或相邻小区的 标识信息。
其中, UE 在获取到阈值配置后, 根据阈值配置设置相应的阈值, 在 获取到至少一个多媒体广播多播业务所属区域对应的区域对应的合并测 量值后,将合并测量值与 UE根据阈值配置信息预先配置的阈值进行比较, 其一种可行的实现方式为: 在仅有一个合并测量值的情况下, UE 预先配 置阈值, 当合并测量值达到预先配置的阈值, 则切换单元 13 根据该合并 测量值决定是否进行小区重选; 或者, 当合并测量值达到预先配置的阈值 时, 切换单元 13 向基站发送上述测量报告消息。 另一种可行的实现方式 为: 当合并测量值低于、 或下降到预先配置的阈值, 则切换单元 13 根据 该合并测量值决定是否进行小区重选; 或者, 当合并测量值低于、 或下降 到预先配置的阈值时, 切换单元 13向基站发送上述测量报告消息。
而相邻小区的标识信息作用在于, 当 UE获知多个相邻小区属于相同 多媒体广播多播业务所属的相同区域时, UE 根据每个相邻小区的标识信 息将该区域内所有相邻小区的参考信号测量值进行合并, 得到合并测量 值; 或者, 当 UE获知当前的服务小区和至少一个相邻小区相同多媒体广 播多播业务所属的相同区域时, UE 根据相邻小区的标识信息和服务小区 的标识信息将该区域内至少一个相邻小区和服务小区参考信号测量值进 行合并, 得到合并测量值。
进一步的, 针对 UE当前的服务小区与至少一个相邻小区属于同一个 MBMS 区域的场景, 则确定单元 11, 具体用于若第一标识与至少一个相 邻小区的多媒体广播多播业务所属区域对应的区域标识相同, 并且服务小 区的频率信息与至少一个相邻小区的频率信息相同, 则确定服务小区与至少 一个相邻小区属于相同多媒体广播多播业务所属的相同区域。
其中, 服务小区的配置信息包含第一标识和服务小区的频率信息, 第一 标识为用户设备当前接收或准备接收的多媒体广播多播业务所属区域对应 的区域标识, 服务小区的频率信息包含服务小区所在的频率和 /或频率层标 识信息。
合并单元 12, 具体用于在测量参考信号时, 若至少一个相邻小区包含 用户设备当前接收或准备接收的多媒体广播多播业务, 则将服务小区的参 考信号测量值与至少一个相邻小区的参考信号测量值进行合并得到合并测 量值。
继续根据上文场景三进行说明: 小区 A、 小区 B属于相同的 MBMS区 域 Areal内的同步小区, 小区 C不属于任何一个 MBMS区域 (例如, 小 区 C为单播小区) 。
具体的, UE 正在小区 A接收 MBMS业务 x, UE测量时将 Areal中小 区 A和小区 B的参考信号测量值合并, 得到合并测量值 a, 并与小区 C的 参考信号测量值进行比较, 从而判断是否在小区 C接收业务 X, 其可以具有 如下两种情况:
情况一: 如果 UE处于非连接状态( RRC_IDLE ) , UE根据 Areal的 合并测量值 a与小区 C的参考信号测量值, 决定是否要在小区 C发起接收 多媒体广播多播业务 X 的请求; 比如: 如果合并测量值 a低于某个预设阈 值、 或合并测量值 a与小区 C的参考信号测量值之差超过预设阈值, 则 UE 在小区 C发起接收多媒体广播多播业务 X的请求;
情况二: 如果 UE处于连接状态 ( RRC_CONNECTED ) , UE 根据合 并测量值 a与小区 C的参考信号测量值,决定是否向基站发送测量报告消息, 比如: 如果合并测量值 a低于某个预设阈值、或合并测量值 a与小区 C的参 考信号测量值之差超过预设阈值, 则 UE在当前服务小区中 (小区 A) 向基 站发送测量报告消息消息,将合并测量值 a与小区 C的参考信号测量值报告 给基站。
进一步的, 小区 A、 小区 B属于相同的 MBMS区域, 小区 C不属于任 何一个 MBMS区域 (例如, 小区 C为单播小区) , UE在小区 A正在接收 或准备多媒体广播多播业务 X, UE不仅需要判断小区 A与小区 B属于相同 MBMS区域, 同时需要确定小区 B 也具有 UE正在接收或准备多媒体广播 多播业务 X, 才能将小区 A与小区 B的参考信号测量值合并。
进一步的,针对 UE的至少两个相邻小区属于同一个 MBMS区域的场 景, 则确定单元 11, 具体用于若至少两个相邻小区的多媒体广播多播业务 所属区域对应的区域标识相同, 并且至少两个相邻小区的频率信息相同, 则确定至少两个相邻小区属于相同多媒体广播多播业务所属的相同区域。
合并单元 12, 具体用于在测量参考信号时, 若至少两个相邻小区包含 用户设备当前接收或准备接收的多媒体广播多播业务, 则将至少两个相邻 小区的参考信号测量值进行合并得到合并测量值。
继续根据上文场景二进行说明: 小区 A不属于任何一个 MBMS区域 (例如, 小区 A为单播小区) , 小区 B与小区 C为 Area3内的两个小区, 其中小区 A为 UE当前的服务小区。
具体的, UE正在小区 A接收业务 X (RRC_CONNECTED状态) , UE 获知小区 B与小区 C具有该 UE当前接收或者准备接收的多媒体广播多播 业务 X (即 UE感兴趣的多媒体广播多播业务) 时, UE根据 Area3合并的 合并测量值 c与小区 A的参考信号测量值, 决定是否需要通过 Area3接收 多媒体广播多播业务 X, 比如: 如果 Area3的合并测量值 c高于某个预设阈 值、 或 Area3的合并测量值 c减去小区 A的参考信号测量值之差超过预设 门限, 则 UE可以通过如下两种方式接收业务:
可选的, 方式一: UE在小区 A通知基站断开 RRC连接, 通知消息中可 以包含断开连接的原因指示, 并开始从 Area3接收多媒体广播多播业务 x, 其中, 原值指示用于指示 UE开始从 Area3接收多媒体广播多播业务 x。
方式二: UE在小区 A发送测量报告消息给基站,若基站决定 UE切换到 Area3接收多媒体广播多播业务 X, 则基站发送小区切换指示消息给 UE, 通 知 UE选择到小区 A接收业务 x。
继续根据上文场景一进行说明:小区 A与小区 B为 Areal内的两个小 区, 而小区 C为 Area2内的小区, 其中小区 A为 UE当前的服务小区, UE 正在小区 A中接收多媒体广播多播业务 X, 则 UE的操作如下:
首先, 当 UE获知属于 Areal的小区 B和属于 Area2的小区 C都具有 该 UE当前接收或者准备接收的多媒体广播多播业务 X (即 UE感兴趣的 多媒体广播多播业务) 时, 则 UE将 Areal的参考信号测量值合并得到合 并测量值 a, 并与小区 C的参考信号测量值比较, 决定是否停止在 Areal接 收业务多媒体广播多播业务 X,而是在小区 C中接收多媒体广播多播业务 X; 或者, UE将合并测量值 a与预设阈值进行比较, 决定是否在小区 C接收 多媒体广播多播业务 X, 比如: 如果合并测量值 a低于某个预设阈值、 或合 并测量值 a与小区 C的参考信号测量值之差超过预设阈值, 则 UE在当前 服务小区中 (小区 A) 向基站发送测量报告消息, 将合并测量值 a与小区 C 的参考信号测量值报告给基站。
需要说明的是, Area2中若包含多个小区, 则将该多个小区的参考信号 测量值合并获得合并测量值 b。UE将 Areal的参考信号测量值合并得到合 并测量值 a, 并与 Area2的合并测量值 b, 决定是否停止在 Areal接收业务 多媒体广播多播业务 X,而是在 Area2中接收多媒体广播多播业务 x ;或者, UE将合并测量值 a与预设阈值进行比较, 决定是否在 Area2接收多媒体 广播多播业务 X, 比如: 如果合并测量值 a低于某个预设阈值、 或合并测量 值 a与合并测量值 b之差超过预设阈值,则 UE在当前服务小区中(小区 A) 向基站发送测量报告消息,将合并测量值 a与 Area2的参考信号测量值报告 给基站。
进一步, 若小区 A为 UE当前的服务小区, UE确定小区 A/小区 B属于 相同的 Areal ,并确定小区 B具有该 UE当前接收或者准备接收的多媒体广 播多播业务 X (即 UE感兴趣的多媒体广播多播业务) 时, 才可以将小区 A/小区 B参考信号测量值合并。上文中个各实施例以及任意一种可行的实现 方式中涉及到的阈值, 都是通过上文所述的 UE接收基站发送的阈值配置信 息, 并根据该阈值配置信息预先设置得到的。 对于多媒体广播多播业务所 属区域为单频网区域的特定场景时, 上述各实施例以及任意一种实现方式 中"相邻小区的多媒体广播多播业务所属区域对应的区域标识"具体为相邻 小区的单频网区域标识, 第一标识具体为用户设备当前接收或准备接收的多 媒体广播多播业务所属区域对应的单频网区域标识。
并且, UE依据测量进行小区重选, 即选择信号质量较好的小区接收业 务 o
图 3为本发明实施例提供的一种无线网络中保证业务连续接收的方法 的流程示意图, 该方法的执行主体为用户设备 UE, 具体的, 该 UE可以 为包括手机、平板电脑、 PDA (Personal Digital Assistant,个人数字助理)、 POS (Point of Sales, 销售终端) 、 车载电脑等用户设备, 参照图 3, 该方 法包括如下步骤:
步骤 100、 用户设备 UE获取至少一个相邻小区的配置信息。
步骤 101、 UE根据服务小区的配置信息和至少一个相邻小区的配置信 息, 确定包括服务小区和至少一个相邻小区在内的全部小区中, 存在至少两 个小区属于相同多媒体广播多播业务区域。
步骤 102、 UE在测量参考信号时, 将属于相同多媒体广播多播业务所 属的相同区域的至少两个小区的参考信号测量值进行合并得到合并测量 值; 或者, 将属于相同多媒体广播多播业务所属的相同区域的至少两个小区 的参考信号合并, 测量得到合并测量值。
步骤 103、 UE根据合并测量值决定是否进行小区重选; 或者, 触发向 基站发送测量报告, 并向基站发送测量报告消息, 测量报告消息包含合并 测量值, 以使基站根据合并测量值决定是否进行小区切换。
需要说明的是, 在 UE获得合并测量值之后, 对于处于非连接状态的 UE, 该 UE 根据合并测量值进行小区重选的判断; 对于处于连接状态的 UE,该 UE触发向基站发送测量报告,将测量结果发送给服务小区的基站, 由该基站根据合并测量值决定是否进行小区切换。
继续参照图 1, 以小区 A、 小区 B和小区 C三个小区为例, 对 UE在 属于不同 MBMS区域的两个基站间移动, 或者 UE在一个属于 MBMS区 域的基站和一个属于非 MBMS 区域基站间移动这两种场景中, 在采用本 实施例的无线网络信号质量测量方法进行无线信号质量测量进行说明。
场景一: 若小区 A与小区 B为属于 Areal的两个小区, 而小区 C为 属于 Area2的小区, 其中小区 A为 UE当前的服务小区 (或驻留小区) , 由于不同的 MBMS区域的多媒体广播多播业务可能是相同的, 因此当 UE 获知当前接收或者准备接收的 Areal中的多媒体广播多播业务(即 UE感 兴趣的多媒体广播多播业务)在相邻区域 Area2 中也正在发送,则 UE 可 以将 Areal的参考信号测量值则 UE的合并单元 12将 Areal小区 A的参 考信号测量值与小区 B的参考信号测量值进行合并获得合并测量值 a, 即 Areal 的信号质量测量值, 随后 UE根据该合并测量值 a决定是否进行小 区重选, 该过程也可以称为区域重选, 即 UE 从 Areal 的小区中接收业 务重新选择到从 Area2 的小区中接收业务, 或者, UE向基站发送测量报 告消息, 该报告中包含合并测量值 a, 以使基站根据该合并测量值 a决定 是否进行小区切换, 如果基站决定进行小区切换, 则基站发送小区切换命 令给 UE; 该过程也可以称为区域切换, 即 UE 从 Areal 的小区中接收 业务切换到从 Area2 的小区中接收业务, 如果基站决定进行区域切换, 则基站发送区域切换命令给 UE,该消息中至少包含 UE 所要切换到的目 标区域的标识信息, 比如: Area标识、 Area所在频率标识。 具体的, 一 种可行的实现方式为: UE 根据预先配置的阈值, 决定是否要发起小区重 选、 区域重选, 或小区切换、 区域切换, 该预先配置的阈值, 可以是基站 通过专用消息通知给 UE,也可以通过广播消息广播给 UE,还可以是 UE 内部实现的一个配置阈值; 当合并测量值 a 达到预先配置的阈值时, 则 UE根据该合并测量值 a决定不进行小区重选、 或不进行区域重选, 例如 当合并测量值 a上升到、 或超过预先配置的阈值, 说明此时 Areal的无线 网络信号质量符合 UE接收业务的要求, 则 UE依然通过 Areal接收或准 备接收多媒体广播多播业务,而不会选择 Area2中的小区 C或小区 D作为 接收、 准备接收业务的小区, 或不会选择 Area2 作为接收、 准备接收业 务的区域; 或者, 当合并测量值 a达到预先配置的阈值, 触发 UE向基站 发送上述测量报告消息。 另一种可行的实现方式为: 当合并测量值 a低于 或下降到预先配置的阈值,则 UE根据该合并测量值 a决定进行小区重选、 或进行区域重选; 或者, 当合并测量值 a低于或下降到预先配置的阈值, 则触发 UE向基站发送上述测量报告消息。 下文会对 UE如何配置阈值进 行详细说明。
进一步的, 若 Area2中除了小区 C, 还包含小区 D, 并且属于 Area2 的小区 C和小区 D都具有该 UE当前接收或者准备接收的多媒体广播多播 业务 (即 UE感兴趣的多媒体广播多播业务) 时, 则 UE将 Area2中小区 C的参考信号测量值与小区 D的参考信号测量值进行合并获得合并测量值 b。 此时, UE同时得到 Areal的合并测量值 a与 Area2的合并测量值 b, UE根据合并测量值 a与合并测量值 b决定是否进行小区重选、 或区域重 选; 或者, UE依据合并测量值 a与合并测量值 b决定是否触发测量报告 消息, 如果决定触发测量报告消息, 则向基站发送测量报告消息消息, 该 测量报告消息消息中包含合并测量值 a与合并测量值 b, 以使基站根据合 并测量值 a与合并测量值 b决定是否进行小区切换, 如果基站决定进行小 区切换, 则基站发送小区切换命令给 UE; 该过程也可以称为区域切换, 即 UE 从 Areal 的小区中接收业务切换到从 Area2 的小区中接收业务, 如果基站决定进行区域切换, 则基站发送区域切换命令给 UE, 该消息中 至少包含 UE 所要切换到的目标区域的标识信息, 比如: Area标识、 Area 所在频率标识。 具体的, 一种可行的实现方式为: UE将合并测量值 a与 合并测量值 b进行比较, 进一步的, UE可以将合并测量值 a与合并测量 值 b直接进行比较, 或者, 也可以将合并测量值 a与合并测量值 b的差值 与预设阈值进行比较, 比如: 合并测量值 a 与 b 的差是否达到、 或超过 预设阈值; 若合并测量值 a优于合并测量值 b, 由于 UE当前的服务小区 为小区 A, 因此, UE依然通过 Areal接收或准备接收多媒体广播多播业 务, 而不会选择 Area2中的小区 C或小区 D; 若合并测量值 b优于合并测 量值 a, 则选择 Area2接收或准备接收多媒体广播多播业务, 具体的, UE 将选择 Area2中的小区 C或小区 D作为服务小区;另一种可行的实现方式: 切换单元 13向基站发送测量报告消息,该测量报告消息包含合并测量值 a 与合并测量值 b, 该基站将合并测量值 a与合并测量值 b进行比较, 具体 的, UE可以将合并测量值 a与合并测量值 b直接进行比较, 或者, 也可 以将合并测量值 a与合并测量值 b的差值与预设阈值进行比较, 若合并测 量值 a优于合并测量值 b, 由于 UE当前的服务小区为小区 A, 因此, 基 站指示 UE不进行切换, 并依然通过 Areal接收或准备接收多媒体广播多 播业务, 而不会切换至 Area2中的小区 C或小区 D; 若合并测量值 b优于 合并测量值 a, 则基站指示 UE切换至 Area2接收或准备接收多媒体广播 多播业务, 具体的, 基站指示 UE切换至 Area2中的小区 C或小区 D。
需要说明的是, 对于场景一, UE 或者服务小区的基站需要预先获知 两个 MBMS区域具有 UE当前接收或准备接收的多媒体广播多播业务;如 果某一个 MBMS区域中没有 UE正在接收或准备接收的多媒体广播多播业 务, 则 UE不能选择该 MBMS区域接收多媒体广播多播业务, 即在进行区 域选择的测量时, 只考虑包含 UE正在接收或准备接收的多媒体广播多播 业务区域, 或者在测量报告消息中包含 UE正在接收或准备接收的多媒体 广播多播业务区域的测量结果, 不包含没有发送 UE正在接收或准备接收 的多媒体广播多播业务区域的测量结果, 基站不能指示 UE 切换至该 MBMS 区域, 否则业务会中断。 但是, 对于 UE从 MBMS区域中的一个 小区向单播小区切换时, 则没有该限制, 因为单播业务是为 UE建立的专 用传输资源, 因此不受该限制。
场景二: 小区 A不属于任何一个 MBMS区域 (例如, 小区 A为单播 小区) , 小区 B与小区 C为 Area3内的两个小区, 其中小区 A为 UE当前 的服务小区 (或驻留小区) , 当 UE当前接收或者准备接收的小区 A中的 多媒体广播多播业务 (即 UE感兴趣的多媒体广播多播业务) 在相邻小区 Area3中也正在发送, 则 UE将 Area3中小区 B的参考信号测量值与小区 C的参考信号测量值进行合并获得合并测量值 c, 即 Area3的信号质量测 量值, 随后 UE根据该合并测量值 c决定是否进行小区重选、或区域重选, 或者, UE根绝该合并测量值 c 决定是否触发测量报告, 并向基站发送测 量报告消息, 该测量报告消息中包含合并测量值 c, 以使基站根据该合并 测量值 c 决定是否进行小区切换。 具体的, 一种可行的实现方式为: UE 根据预先配置的阈值, 决定是否要发起小区重选、区域重选, 或小区切换、 区域切换, 该预先配置的阈值, 可以是基站通过专用消息通知给 UE, 也 可以通过广播消息广播给 UE, 还可以是 UE 内部实现的一个配置阈值; 当合并测量值 c达到预先配置的阈值, 则 UE根据该合并测量值 c决定是 否进行小区重选、或区域重选,例如当合并测量值 c达到预先配置的阈值, 说明此时 Area3的无线网络信号质量符合 UE接收广播多播业务数据的要 求, 则 UE选择通过 Area3接收或准备接收多媒体广播多播业务; 或者, UE 触发测量报告, 并向基站发送上述测量报告消息。 另一种可行的实现 方式为: 当合并测量值 c低于 /或下降到预先配置的阈值, 则 UE根据该合 并测量值 c决定是否进行小区重选、 或区域重选; 或者, 当合并测量值 c 低于 /或下降到预先配置的阈值时, UE触发向基站发送上述测量报告。
场景三: 小区 A与小区 B为属于 Areal的两个小区, 小区 C不属于 任何一个 MBMS区域 (例如, 小区 C为单播小区) , UE 正在接收、 或 准备接收 Area l中广播的业务 X, 并且 UE 确定在小区 C 中支持广播多 播业务 X 的传输, 则 UE将属于 Areal中小区 A的参考信号测量值与小 区 B的参考信号测量值进行合并获得合并测量值 a,即 Areal 的信号质量 测量值, 随后 UE根据该合并测量值 a决定是否进行小区重选, 或者, UE 决定是否触发测量报告, 如果 UE决定向基站发送测量报告消息, 该测量 报告消息中包含合并测量值 a, 以使基站根据该合并测量值 a决定是否进 行小区切换。 具体的, 一种可行的实现方式为: UE根据预先配置的阈值, 将合并测量值 a与预先配置的阈值比较, UE根据该合并测量值 a与预先 配置的阈值比较结果决定是否进行小区重选、 或区域重选, 例如当合并测 量值 a达到、 或超过预先配置的阈值, 说明此时 Areal的无线网络信号质 量符合 UE的要求, 则 UE依然通过 Area3接收或准备接收多媒体广播多 播业务, 不需要选择小区 C作为服务小区; 或者, 当合并测量值 a达到预 先配置的阈值, 触发 UE向基站发送上述测量报告消息。 另一种可行的实 现方式为: 当合并测量值 a低于、 或下降到预先配置的阈值, 则 UE根据 该合并测量值 a决定是否进行小区重选; 或者, 当合并测量值 a低于、 或 下降到预先配置的阈值, 触发 UE向基站发送上述测量报告消息。
进一步的, 对于场景二和场景三, 另一种可行的实现方式为: UE 将 具有相同多媒体广播多播业务所属的相同区域的合并测量值与不属于任何 多媒体广播多播业务所属的区域的其他小区的参考信号测量值进行比较, 从而决定是否进行小区重选、 或进行区域重选; 或者, UE 将包含合并测 量值和参考信号测量值的测量报告消息发送给基站, 基站将合并测量值与 其他小区的参考信号测量值进行比较, 决定是否进行小区切换, 该实现方 式将在下文中进行详细说明。
对于场景一、 二、 三, 在 UE 进行区域信号质量测量之前, 基站可 以通过专用消息、 或系统广播发送区域测量配置消息给 UE, 该测量配置 消息中包含一下任意一种或任意组合的参数: 待测量的区域标识信息; 待 测量区域信号质量类型, 比如: 参考信号接收功率 (Reference Signal Receiving Power, 简称: RSRP)和 /或参考信号接收质量( Reference Signal Receiving Quality , 简称: RSRQ) 。
进一步的, 还可以包含: 待测量区域的频点信息; 待测量区域所对应 的小区标识信息; 需要删除的待测量的区域标识信息; 需要更新的待测量 的区域标识信息。
需要说明的是, 本发明各个实施例中涉及的 MBMS 区域, 其最小的 单元为一个小区, 即一个 MBMS 区域包含至少一个小区。 另外, 本实施 例中以三个小区进行说明, 对于 UE在移动过程中获取到多少个相邻小区 的配置信息根据实际的小区分布场景来决定, 本实施例不做限定, 只要确定 多个小区属于同一个 MBMS区域, 则将属于同一 MBMS区域的全部小区 的参考信号测量值进行合并, 再根据不同 MBMS 区域的合并测量值, 或 者根据 MBMS区域的合并测量值与非 MBMS区域的小区的参考信号测量 值由 UE决定是否进行小区重选, 或者由基站决定是否进行小区切换。 本实施例提供的无线网络中保证业务连续接收的方法, 通过用户设备
UE获取至少一个相邻小区的配置信息, UE根据服务小区的配置信息和至少 一个相邻小区的配置信息, 确定包括所述服务小区和至少一个相邻小区在内 的全部小区中, 存在至少两个小区属于相同多媒体广播多播业务所属的相同 区域, 之后, UE在测量参考信号时, 将属于相同多媒体广播多播业务所属 的相同区域的至少两个小区的参考信号测量值进行合并得到合并测量值; 或者, 将属于相同多媒体广播多播业务所属的相同区域的至少两个所述小区 的参考信号合并, 测量得到合并测量值; 根据合并测量值决定是否进行小 区重选; 或者, 触发向基站发送测量报告, 并向基站发送测量报告消息, 测量报告消息包含所述合并测量值, 以使基站根据合并测量值决定是否进 行小区切换。 从而在后续的切换判断过程中, UE 或服务小区的基站考虑 到 MBMS 区域整体的信号强度, 避免低估单个小区无线信号质量, 从而 避免了引发不必要的切换流程, 使得切换时机更加合理, 从而保证了 UE 获得的无线信号的质量。
需要说明的是, 在 LTE 无线通信网络中, 为了确定 UE 所在位置的 无线信号质量, UE 需要对其服务或驻留小区进行参考信号的测量, 考虑 到 UE 的移动性 UE 也需要进行相邻小区进行测量, 这些测量量包括参 考信号接收功率 (Reference Signal Received Power, 简称: RSRP) 和参考 信号接收质量 (Reference Signal Received Quality, 简称: RSRQ) 等等。 而 RSRP和 RSRQ是所有测量量中比较重要的测量量。
其中, RSRP为参考信号接收功率,定义为测量带宽内承载所有测量 RSRP 用的 CRS端口对应资源单元(Resource Element, 简称: RE)上对应小区特定 参考信号(Cell-specific Reference Signal , 简称: CRS) 的接收功率的线性平 均值。针对 RSRP的测量, UE需要使用 CRS端口 0进行测量。 当 UE能够可靠检 测到 CRS端口 1时, UE可以在使用 CRS端口 0的同时使用端口 1和端口 0—起来 确定 RSRP。 RSRQ为 NxRSRP/(E-UTRA carrier RSSI), 其中 N为 E-UTRA系统 中用于测量 E-UTRA网络承载接收信号强度指示 ( E-UTRA carrier Received Signal Strength Indicator) 测量带宽的资源块 (Resource Block , 简称: RB ) 个数。 其中分子和分母需要对应相同的资源数量。 E-UTRA carrier RSSI为在 规定的测量带宽内 N个 RB上测量到的承载 CRS参考信号天线端口 0的 OFDM 符号上的总接收功率的线性平均值, 包括服务小区的共道干扰、 非服务小区 产生的干扰, 邻道干扰, 热噪声等等。 如果高层信令指示了用于测量 RSRQ 的特定的子帧, 那么 RSSI将从对应子帧的所有 OFDM符号上测量。
UE测量到的一个小区的 RSRP越大, 则 UE从该小区接收到的信号越强; UE测量到的一个小区的 RSRQ越大, 则 UE从该小区接收到的信号质量越高。
UE进行 RRM无线资源管理 (Radio Resource Management) 的测量(包括 RSRP, RSRQ, RSSI的测量) , 是在测量带宽内, 一个时间范围内多次测量 后求线性平均来得到对应的 RRM测量值。 如在 200ms内测量 5次 RSRP测量值 后通过线性平均, 得到对应的 RSRP测量值。
其中, RRM测量值主要用于 UE的移动性管理等。如 RSRP代表一个 小区到 UE的参考信号的平均接收功率, 当 UE在向远离小区 B的方向移 动时, UE测量反馈的小区 B的 RSRP在逐渐变小, 而当 UE在向靠近小 区 A的方向移动时, UE测量反馈的小区 A的 RSRP在逐渐变大。 即 UE 在移动时, 不断测量反馈 RRM各测量值, 然后基站通过对应的 RRM测 量值, 来发现是否需要改变为 UE提供服务的小区等。
进一步的, 由于 UE决定重选小区或者基站指示 UE切换小区后, 若 目标小区为单播传输小区, 则需要 UE 当前接收或准备接收的多媒体广播 多播业务是否支持单播传输, 因此, 进一步的, UE还需要获取 UE当前接 收或准备接收的多媒体广播多播业务的单播传输指示信息。该单播传输指示 信息用以指示该业务是否支持单播传输指示信息, 若单播传输指示信息指示 该业务支持单播传输, 则在上述测量结果满足小区重选条件下, 则 UE决定 进行小区重选。
或者,上述 UE当前接收或准备接收的多媒体广播多播业务的单播传输 指示信息也可以由基站获取, 当基站接收到 UE发送的测量报告消息后, 若 根据测量报告消息中包含的测量结果判断满足小区切换的条件并且目标 小区为单播传输小区, 则此时基站根据该业务的单播传输指示信息判断该 业务是否支持单播传输, 若单播传输指示信息指示该业务支持单播传输, 则 基站指示 UE进行小区切换。
需要说明的是, 对于上述两种情况, 若单播传输指示信息指示该业务不 支持单播传输, 则 UE不会选择该目标小区作为服务小区; 基站不会指示 UE 切换至该目标小区。
进一步的, 对于服务小区不属于任何一个 MBMS 区域, 并且至少两 个相邻小区属于一个 MBMS区域 Area3;服务小区与至少一个相邻小区属 于一个 MBMS区域 Areal,并且至少一个相邻小区不属于任何一个 MBMS 区域的两种场景, 除了采用上述 UE根据合并测量值决定是否进行小区重 选或者基站根据合并测量值决定是否进行小区切换的方式之外, 图 3中步 骤 103可以通过如下可行的实现方式实现:
步骤 103a、将合并测量值与至少一个其他小区的参考信号测量值进行 比较, 决定是否进行小区重选; 或者,
步骤 103b、 向基站发送的测量报告消息除了包含合并测量值外, 还包 含至少一个其他小区的参考信号测量值, 以使基站将合并测量值与至少一 个其他小区的参考信号测量值进行比较, 决定是否进行小区切换。
其中, 其他小区指包括服务小区和至少一个相邻小区在内的全部小区中 不属于任何多媒体广播多播业务所属的区域的小区。
具体步骤 103a与步骤 103b的实现方式可以参照上文中所述场景二和 场景三的方案说明, 此处不再赘述。
需要说明的是, 上述三个场景仅对具有三个小区的情况进行了说明, 当有多个 MBMS区域中包含至少两个小区, 并且每个 MBMS区域都具有 该 UE当前接收或者准备接收的多媒体广播多播业务 (即 UE感兴趣的多 媒体广播多播业务) 时, 则分别合并每个 MBMS 区域中的参考信号测量 值, 获得每个 MBMS区域的合并测量值, UE在将多个合并测量值进行比 较, 或者与预先配置的阈值进行比较, 其具体的比较方式与上文的比较方 式类似, 从而由 UE决定是否进行小区重选; 或者, 触发 UE向基站发送 测量报告消息, 以使基站决定是否进行小区切换。
进一步的, 图 1步骤 100可以通过如下方式获取配置信息:
实现方式 1 :
步骤 100a、 UE接收源基站发送的至少一个相邻小区的广播多播信号测 量配置消息, 相邻小区的广播多播信号测量配置消息包含相邻小区的配置 信息。
实现方式 2: 步骤 100b、 UE读取源基站发送的广播,广播包含相邻小区的配置信息。 对于实现方式 1和实现方式 2, 其中, 相邻小区的配置信息具体包含相 邻小区的多媒体广播多播业务所属区域对应的区域标识和相邻小区的频率 信息, 其中, 相邻小区的频率信息包含相邻小区所在的频率和 /或频率层标 识信息。
根据相邻小区的多媒体广播多播业务所属区域对应的区域标识和相邻 小区的频率信息, 获知测量目标的频率层和 /或广播多播区域对应一个小 区, 则 UE 仅测量该小区的广播多播参考信号, 并将该小区的参考信号测 量值作为目标区域的频率层和 /或广播多播区域的广播多播参考信号的参 考信号测量值; 一个频率层标识信息可以对应一个或多个广播多播小区标识 信息; 一个广播多播区域可以对应一个或多个广播多播小区标识信息;
根据相邻小区的多媒体广播多播业务所属区域对应的区域标识和相邻 小区的频率信息, 获知测量目标的频率层和 /或广播多播区域对应多个小 区, 则 UE将属于目标的频率层和、 或广播多播区域对应多个小区的广播 多播参考信号合并测量;或分别对属于目标的频率层和 /或广播多播区域对 应多个小区的广播多播参考信号进行单独测量, 并将测量结果合并为合并 测量值, 合并测量值作为目标的频率层和、 或广播多播区域的广播多播参 考信号的测量结果; UE 也可以通过对相邻小区的测量, 发现属于所要测 量目标的频率层和 /或广播多播区域所包含的小区。
进一步的, 相邻小区的配置信息还包含阈值配置信息和 /或相邻小区的 标识信息。
其中, UE 在获取到阈值配置后, 根据阈值配置设置相应的阈值, 在 获取到至少一个多媒体广播多播业务所属区域对应的区域对应的合并测 量值后,将合并测量值与 UE根据阈值配置信息预先配置的阈值进行比较, 其一种可行的实现方式为: 在仅有一个合并测量值的情况下, UE 预先配 置阈值, 当合并测量值达到预先配置的阈值, 则 UE根据该合并测量值决 定是否进行小区重选; 或者, 当合并测量值达到预先配置的阈值时, UE 向基站发送上述测量报告消息。 另一种可行的实现方式为: 当合并测量值 低于、 或下降到预先配置的阈值, 则 UE根据该合并测量值决定是否进行 小区重选; 或者, 当合并测量值低于、 或下降到预先配置的阈值时, UE 向基站发送上述测量报告消息。
而相邻小区的标识信息作用在于, 当 UE获知多个相邻小区属于相同 多媒体广播多播业务所属的相同区域时, UE 根据每个相邻小区的标识信 息将该区域内所有相邻小区的参考信号测量值进行合并, 得到合并测量 值; 或者, 当 UE获知当前的服务小区和至少一个相邻小区相同多媒体广 播多播业务所属的相同区域时, UE 根据相邻小区的标识信息和服务小区 的标识信息将该区域内至少一个相邻小区和服务小区参考信号测量值进 行合并, 得到合并测量值。
进一步的, 针对 UE当前的服务小区与至少一个相邻小区属于同一个 MBMS区域的场景, 图 3中步骤 101的一种可行的实现方式为:
步骤 101a、 若第一标识与至少一个相邻小区的多媒体广播多播业务所 属区域对应的区域标识相同, 并且服务小区的频率信息与至少一个相邻小 区的频率信息相同, 则 UE确定服务小区与至少一个相邻小区属于相同多媒 体广播多播业务所属的相同区域。
其中, 服务小区的配置信息包含第一标识和服务小区的频率信息, 第一 标识为用户设备当前接收或准备接收的多媒体广播多播业务所属区域对应 的区域标识, 服务小区的频率信息包含服务小区所在的频率和 /或频率层标 识信息。
对于图 3中步骤 102的一种可行的实现方式为:
步骤 102a、 UE在测量参考信号时, 若至少一个相邻小区包含 UE当前 接收或准备接收的多媒体广播多播业务, 则将服务小区的参考信号测量值 与至少一个相邻小区的参考信号测量值进行合并得到合并测量值。
继续根据上文场景三进行说明: 小区 A、 小区 B属于相同的 MBMS区 域 Areal内的同步小区, 小区 C不属于任何一个 MBMS区域 (例如, 小 区 C为单播小区) 。
具体的, UE 正在小区 A接收 MBMS业务 x, UE测量时将 Areal中小 区 A和小区 B的参考信号测量值合并, 得到合并测量值 a, 并与小区 C的 参考信号测量值进行比较, 从而判断是否在小区 C接收业务 X, 其可以具有 如下两种情况:
情况一: 如果 UE处于非连接状态( RRC_IDLE ) , UE根据 Areal的 合并测量值 a与小区 C的参考信号测量值, 决定是否要在小区 C发起接收 多媒体广播多播业务 X 的请求; 比如: 如果合并测量值 a低于某个预设阈 值、 或合并测量值 a与小区 C的参考信号测量值之差超过预设阈值, 则 UE 在小区 C发起接收多媒体广播多播业务 X的请求;
情况二: 如果 UE处于连接状态 ( RRC_CONNECTED ) , UE根据合 并测量值 a与小区 C的参考信号测量值,决定是否向基站发送测量报告消息, 比如: 如果合并测量值 a低于某个预设阈值、或合并测量值 a与小区 C的参 考信号测量值之差超过预设阈值, 则 UE在当前服务小区中 (小区 A) 向基 站发送测量报告消息消息,将合并测量值 a与小区 C的参考信号测量值报告 给基站。
进一步的, 小区 A、 小区 B属于相同的 MBMS区域, 小区 C不属于任 何一个 MBMS区域 (例如, 小区 C为单播小区) , UE在小区 A正在接收 或准备多媒体广播多播业务 X, UE不仅需要判断小区 A与小区 B属于相同 MBMS区域, 同时需要确定小区 B 也具有 UE正在接收或准备多媒体广播 多播业务 X, 才能将小区 A与小区 B的参考信号测量值合并。
进一步的,针对 UE的至少两个相邻小区属于同一个 MBMS区域的场 景, 图 3中步骤 101的一种可行的实现方式为:
步骤 101b、若至少两个相邻小区的多媒体广播多播业务所属区域对应 的区域标识相同, 并且至少两个相邻小区的频率信息相同,则 UE确定至少 两个相邻小区属于相同多媒体广播多播业务所属的相同区域。
对于图 3中步骤 102的一种可行的实现方式为:
步骤 102b、 UE在测量参考信号时, 若至少两个相邻小区包含用户设 备当前接收或准备接收的多媒体广播多播业务,则将至少两个相邻小区的参 考信号测量值进行合并得到合并测量值。
继续根据上文场景二进行说明: 小区 A不属于任何一个 MBMS区域
(例如, 小区 A为单播小区) , 小区 B与小区 C为 Area3内的两个小区, 其中小区 A为 UE当前的服务小区。
具体的, UE正在小区 A接收业务 X (RRC_CONNECTED状态) , UE 获知小区 B与小区 C具有该 UE当前接收或者准备接收的多媒体广播多播 业务 X (即 UE感兴趣的多媒体广播多播业务) 时, UE根据 Area3合并的 合并测量值 c与小区 A的参考信号测量值, 决定是否需要通过 Area3接收 多媒体广播多播业务 X, 比如: 如果 Area3的合并测量值 c高于某个预设阈 值、 或 Area3的合并测量值 c减去小区 A的参考信号测量值之差超过预设 门限, 则 UE可以通过如下两种方式接收业务:
可选的, 方式一: UE在小区 A通知基站断开 RRC连接, 通知消息中可 以包含断开连接的原因指示, 并开始从 Area3接收多媒体广播多播业务 x, 其中, 原值指示用于指示 UE开始从 Area3接收多媒体广播多播业务 x。
方式二: UE在小区 A发送测量报告消息给基站,若基站决定 UE切换到 Area3接收多媒体广播多播业务 X, 则基站发送小区切换指示消息给 UE, 通 知 UE选择到小区 A接收业务 x。
继续根据上文场景一进行说明:小区 A与小区 B为 Areal内的两个小 区, 而小区 C为 Area2内的小区, 其中小区 A为 UE当前的服务小区, UE 正在小区 A中接收多媒体广播多播业务 X, 则 UE的操作如下:
首先, 当 UE获知属于 Areal的小区 B和属于 Area2的小区 C都具有 该 UE当前接收或者准备接收的多媒体广播多播业务 X (即 UE感兴趣的 多媒体广播多播业务) 时, 则 UE将 Areal的参考信号测量值合并得到合 并测量值 a, 并与小区 C的参考信号测量值比较, 决定是否停止在 Areal接 收业务多媒体广播多播业务 X,而是在小区 C中接收多媒体广播多播业务 X; 或者, UE将合并测量值 a与预设阈值进行比较, 决定是否在小区 C接收 多媒体广播多播业务 X, 比如: 如果合并测量值 a低于某个预设阈值、 或合 并测量值 a与小区 C的参考信号测量值之差超过预设阈值, 则 UE在当前 服务小区中 (小区 A) 向基站发送测量报告消息, 将合并测量值 a与小区 C 的参考信号测量值报告给基站。
需要说明的是, Area2中若包含多个小区, 则将该多个小区的参考信号 测量值合并获得合并测量值 b。UE将 Areal的参考信号测量值合并得到合 并测量值 a, 并与 Area2的合并测量值 b, 决定是否停止在 Areal接收业务 多媒体广播多播业务 X,而是在 Area2中接收多媒体广播多播业务 x ;或者, UE将合并测量值 a与预设阈值进行比较, 决定是否在 Area2接收多媒体 广播多播业务 X, 比如: 如果合并测量值 a低于某个预设阈值、 或合并测量 值 a与合并测量值 b之差超过预设阈值,则 UE在当前服务小区中(小区 A) 向基站发送测量报告消息,将合并测量值 a与 Area2的参考信号测量值报告 给基站。
进一步, 若小区 A为 UE当前的服务小区, UE确定小区 A/小区 B属于 相同的 Areal ,并确定小区 B具有该 UE当前接收或者准备接收的多媒体广 播多播业务 X (即 UE感兴趣的多媒体广播多播业务) 时, 才可以将小区 A/小区 B参考信号测量值合并。上文中个各实施例以及任意一种可行的实现 方式中涉及到的阈值, 都是通过上文所述的 UE接收基站发送的阈值配置信 息, 并根据该阈值配置信息预先设置得到的。 对于多媒体广播多播业务所 属区域为单频网区域的特定场景时, 上述各实施例以及任意一种实现方式 中"相邻小区的多媒体广播多播业务所属区域对应的区域标识"具体为相邻 小区的单频网区域标识, 第一标识具体为用户设备当前接收或准备接收的多 媒体广播多播业务所属区域对应的单频网区域标识。
并且, UE依据测量进行小区重选, 即选择信号质量较好的小区接收业 务 o
