Description

测量报告的发送方法及用户设备 技术领域
本发明涉及一种通信领域， 特别涉及一种测量报告的发送方法及用 户设备。 背景技术 目前， 第三代合作伙伴计划 （3GPP: The 3rd Generation Partnership Project) 组织已开始对第四代 （4G) 移动通信系统， 如高级的长期演进 ( LTE-A： Long Term Evolution Advanced)系统进行研究。
在 Rel-11基站中， 能够保证 Rel-11用户设备的多媒体广播组播服务 的连续性。具体而言，在 Rel-11基站中可以为 Rel-11用户设备提供 MBMS 服务的连续性； 具体方法是 Rel-11基站和 Rel-11用户设备相互提供有关 MBMS服务的信息，这样 Rel-11基站就可以知道 Rel-11用户设备的兴趣， 从而准确的将其切换到合适的基站。
但是， 在发明人实现本发明的过程中发现， 现有的机制没有考虑过 Rel-11用户设备在 pre-Rel- 11 (例如 Rel-10或之前的版本） 基站间切换， 或由 pre-Rel-11 基站切换到 Rel-11 基站时 MBMS 服务的连续性。 在 pre-Rel- 11 的基站中， Rel-11用户设备向其发送的一些与 MBMS服务连 续性有关的信息是不能被理解的， 因此不能很好地保证 MBMS服务的连 续性。
应该注意， 上面对技术背景的介绍只是为了方便对本发明的技术方 案进行清楚、 完整的说明， 并方便本领域技术人员的理解而阐述的。 不 能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技 术方案为本领域技术人员所公知。 发明内容
本发明实施例提供一种测量报告的发送方法及用户设备， 目的在于 用户设备在进行切换时很好地保证 MBMS服务的连续性。
根据本发明实施例的一个方面， 提供一种测量报告的发送方法， 所 述发送方法包括：
用户设备在进行切换时， 延迟或不发送第一频率的测量报告； 其中， 所述第一频率不提供所述用户设备感兴趣的多媒体广播组播服务。
根据本发明实施例的又一个方面， 提供一种用户设备， 所述用户设 备包括：
第一发送单元， 在所述用户设备进行切换时， 延迟或不发送第一频 率的测量报告； 其中， 所述第一频率不提供所述用户设备感兴趣的多媒 体广播组播服务。
根据本发明实施例的又一个方面， 提供一种计算机可读程序， 其中 当在用户设备中执行所述程序时， 所述程序使得计算机在所述用户设备 中执行如上所述的测量报告的发送方法。
根据本发明实施例的又一个方面， 提供一种存储有计算机可读程序 的存储介质， 其中所述计算机可读程序使得计算机在用户设备中执行如 上所述的测量报告的发送方法。
本发明实施例的有益效果在于， 通过用户设备在进行切换时， 延迟 或不发送不提供用户设备感兴趣的 MBMS服务的频率的测量报告， 可以 使得提供用户设备感兴趣的 MBMS服务的频率的测量报告被最先发送， 由此可以很好地保证 MBMS服务的连续性。
参照后文的说明和附图， 详细公开了本发明的特定实施方式， 指明 了本发明的原理可以被采用的方式。 应该理解， 本发明的实施方式在范 围上并不因而受到限制。 在所附权利要求的精神和条款的范围内， 本发 明的实施方式包括许多改变、 修改和等同。
针对一种实施方式描述和 /或示出的特征可以以相同或类似的方式在 一个或更多个其它实施方式中使用， 与其它实施方式中的特征相组合， 或替代其它实施方式中的特征。
应该强调， 术语"包括 /包含"在本文使用时指特征、 整件、 歩骤或组 件的存在， 但并不排除一个或更多个其它特征、 整件、 歩骤或组件的存 在或附加。 附图说明

具体实施方式
参照附图， 通过下面的说明书， 本发明的前述以及其它特征将变得 明显。 在说明书和附图中， 具体公开了本发明的特定实施方式， 其表明 了其中可以采用本发明的原则的部分实施方式， 应了解的是， 本发明不 限于所描述的实施方式， 相反， 本发明包括落入所附权利要求的范围内 的全部修改、 变型以及等同物。
在本实施例中， 仅以 Rel-11用户设备和 Rel-10基站为例进行说明。 但值得注意的是， 本发明并不限于此， 也可以应用到之前或者之后的版 本中。 本发明中的基站可以是宏小区 （Macro Cell) 基站， 也可以是微小 区 （Pico Cell)基站， 还可以是远端无线头（RRH， Remote Radio Head) , 可根据实际情况确定具体的设备。
图 1 是 Rel-11用户设备在 Rel-10基站之间切换的示意图。 其中该 Rel-11用户设备的 MBMS服务工作在某一频率 _ !， 该用户设备从基站 1 切换到基站 2时， 由于基站 1和 2不能保证 MBMS服务的连续性， 用户 设备接收的 MBMS可能会在切换的过程中被中断。
本发明提供一种测量报告的发送方法， 图 2 是本发明实施例中测量 报告的发送方法的流程图。 如图 2所示， 该方法包括：
歩骤 201， 用户设备在进行切换时， 延迟或不发送第一频率的测量报 告； 其中， 该第一频率不提供用户设备感兴趣的多媒体广播组播服务。
在本实施例中， 用户设备在进行切换时， 可以是从源基站切换到目 的基站； 也可以在同一个基站内部的不同频率间切换。 但不限于此， 可 以根据实际情况确定具体的场景。
在本实施例中， 该第一频率可以为一个， 也可以为多个。 用户设备 可以对多个频率进行测量， 其中 MBMS服务工作在某一频率/ i (第二频 率）， 此外还有一个或多个不提供用户设备感兴趣的 MBMS服务的频率 (第一频率）， 例如 /2， ……。
在本实施例中， 对于这些频率/ 2， /3......， 即使已经满足测量报告的 触发条件， 用户设备也不会立即发送这些频率的测量报告， 而是延迟或 者不发送。 由此， 可以使得提供用户设备感兴趣的 MBMS服务的频率/ i 的测量报告首先被发送， 使得基于/ i进行切换， 从而保证 MBMS服务的 连续性。
在本实施例中， 测量报告的触发条件例如可以是 M m>M s+Offset; 其中， M 表示目标小区的信号强度或信号质量 （如信噪比， 信干燥比 等）， M 表示源小区的信号强度或信号质量 （如信噪比， 信干燥比等）， Offset表示偏移量。 可以参考现有技术， 此处不再赘述。
图 3 是本发明实施例中测量报告的发送方法的又一流程图。 如图 3 所示， 该方法包括：
歩骤 301， 用户设备判断基站是否能保证 MBMS服务的连续性； 在 不能保证 MBMS服务的连续性时， 执行歩骤 302; 在能够保证 MBMS服 务的连续性时， 可以执行歩骤 305。
在本实施例中， 该基站可以是用户设备在同一基站内部切换时所在 的基站； 也可以是用户设备从源基站切换到目的基站时的源基站。 可根 据实际情况确定具体的结构。
在本实施例中， 用户设备可以从基站发送的信息中判断是否能保证
MBMS服务的连续性。 例如， 如果该基站为 Rel-11基站， 则会发送一些 pre-Rel-11基站所不会发送的信息 （如关于提供 MBMS服务的信息）。
因此， 如果 Rel-11用户设备能够收到这些信息， 则可判断该基站为
Rel-11基站， 可以保证 MBMS服务的连续性； 如果 Rel-11用户设备没有 收到这些信息， 则可以判定该基站为 pre-Rel-11基站， 不能保证 MBMS 服务的连续性。
歩骤 302， 用户设备在进行切换时， 判断第二频率是否满足测量报告 的触发条件， 其中第二频率提供用户设备感兴趣的多媒体广播组播服务。 如果第二频率满足测量报告的触发条件， 则执行歩骤 303; 如果第二频率 不满足测量报告的触发条件， 则执行歩骤 304。
歩骤 303， 用户设备立即发送第二频率的测量报告；
在本实施例中， 决定是否立即发送该频率的测量报告时， 可以按照 如下原则： （1 ) 该频率提供了终端感兴趣的 MBMS服务； （2) 该频率的 测量结果满足了测量报告的触发条件。
在一个实施方式中， 可选地， 用户设备还可以设定 MBMS服务的优 先级高于单播业务的优先级。 由此， 触发第二频率/ i的条件更加严格。
在又一个实施方式中， 用户设备在第一频率和第二频率同时满足测 量报告的触发条件时， 仅立即发送第二频率的测量报告。 而现有技术中 多个频率同时满足测量报告的触发条件时， 同时发送该多个频率的测量 报告。 本发明与此不同， 即使多个频率满足测量报告的触发条件， 也仅 立即发送第二频率 的测量报告， 由此可以更好地保证 MBMS服务的连 续性。
歩骤 304， 用户设备延迟或不发送第一频率的测量报告； 其中， 该第 一频率不提供用户设备感兴趣的多媒体广播组播服务。
歩骤 305， 进行正常的测量报告流程。
由此， 可以使得提供用户设备感兴趣的 MBMS服务的频率的测量报 告被最先发送， 可以很好地保证 MBMS服务的连续性。
此外， 如果提供用户设备感兴趣的多媒体广播组播服务的第二频率 迟迟不能满足测量报告的触发条件， 则用户设备还需要进一歩处理。 图 4 是本发明实施例中测量报告的发送方法的又一流程图。 如图 4 所示， 该方法包括：
歩骤 401， 用户设备判断基站是否能保证 MBMS服务的连续性； 在 不能保证 MBMS服务的连续性时， 执行歩骤 402; 在能够保证 MBMS服 务的连续性时， 执行歩骤 406。
歩骤 402， 用户设备在进行切换时， 判断第二频率是否满足测量报告 的触发条件， 其中第二频率提供用户设备感兴趣的多媒体广播组播服务。 如果第二频率满足测量报告的触发条件， 则执行歩骤 403 ; 如果第二频率 不满足测量报告的触发条件， 则执行歩骤 404。
歩骤 403， 用户设备立即发送第二频率的测量报告。
歩骤 404， 用户设备延迟或不发送第一频率的测量报告； 其中， 该第 一频率不提供用户设备感兴趣的多媒体广播组播服务。
歩骤 405， 用户设备判断延迟时间是否超过预设的第一门限值； 在延 迟时间超过预设的第一门限值时， 执行歩骤 406; 在延迟时间没有超过预 设的第一门限值时， 执行歩骤 402。
歩骤 406， 用户设备进行正常的测量报告。
例如， 若某一个第一频率的测量报告的触发条件已经满足， 则发送 该第一频率的测量报告。
图 5 是本发明实施例中测量报告的发送方法的又一流程图。 如图 5 所示， 该方法包括：
歩骤 501， 用户设备判断基站是否能保证 MBMS服务的连续性； 在 不能保证 MBMS服务的连续性时， 执行歩骤 502; 在能够保证 MBMS服 务的连续性时， 执行歩骤 506。
歩骤 502， 用户设备在进行切换时， 判断第二频率是否满足测量报告 的触发条件， 其中第二频率提供用户设备感兴趣的多媒体广播组播服务。 如果第二频率满足测量报告的触发条件， 则执行歩骤 503 ; 如果第二频率 不满足测量报告的触发条件， 则执行歩骤 504。
歩骤 503， 用户设备立即发送第二频率的测量报告。
歩骤 504， 用户设备延迟或不发送第一频率的测量报告； 其中， 该第 一频率不提供用户设备感兴趣的多媒体广播组播服务。
歩骤 505， 判断第一频率的信号强度或信号质量（如信噪比， 信干燥 比等） 超过预设的第二门限值时、 和 /或第二频率的信号强度或信号质量 (如信噪比， 信干燥比等） 低于预设的第三门限值； 在判断结果为是时 执行歩骤 506， 否则执行歩骤 502。
在本实施例中， 如果第一频率的信号强度或信号质量超过预设的第 二门限值， 则可能表明频率 /2， h……等比较重要， 此时可能需要中断 MBMS服务； 或者如果第二频率的信号强度或信号质量低于预设的第三 门限值，则可能表明/ i的测量结果比较差，不适合继续提供 MBMS服务， 此时也可能需要中断 MBMS服务。
歩骤 506， 用户设备进行正常的测量报告。
由上述实施例可知， 通过用户设备在进行切换时， 延迟或不发送不 提供用户设备感兴趣的 MBMS服务的频率的测量报告， 可以使得提供用 户设备感兴趣的 MBMS服务的频率的测量报告被最先发送， 由此可以很 好地保证 MBMS服务的连续性。
本发明实施例还提供一种用户设备， 与上述方法实施例相同的内容， 此处不再赘述。
图 6是本发明实施例的用户设备的构成示意图。 如图 6所示， 该用 户设备 600包括第一发送单元 601 ;其中用户设备 600其他的部分可参考 现有技术， 此处不再赘述。
其中， 第一发送单元 601 用于在进行切换时延迟或不发送第一频率 的测量报告； 其中， 第一频率不提供用户设备感兴趣的 MBMS服务。
由此， 可以使得提供用户设备感兴趣的 MBMS服务的频率的测量报 告被最先发送， 可以很好地保证 MBMS服务的连续性。

其中，判断单元 702用于判断基站是否能保证 MBMS服务的连续性; 并且，第一发送单元 701还用于在基站不能保证 MBMS服务的连续性时， 延迟或不发送第一频率的测量报告。 在具体实施时， 该基站可以为 3GPP Rel-10版本或者之前版本的基 站； 用户设备可以为 Rel-11 UE。

在另一个实施方式中， 第二发送单元 703 还可以用于在第一频率和 第二频率同时满足测量报告的触发条件时， 仅立即发送第二频率的测量 报告。
进一歩地， 第一发送单元 701 还可以用于在延迟时间超过预设的第 一门限值时， 发送第一频率的测量报告。 或者， 第一发送单元 701 还可 以用于在第一频率的信号强度或信号质量超过预设的第二门限值时、 和 / 或第二频率的信号强度或信号质量低于预设的第三门限值时， 发送第一 频率的测量报告。
由上述实施例可知， 通过用户设备在进行切换时， 延迟或不发送不 提供用户设备感兴趣的 MBMS服务的频率的测量报告， 可以使得提供用 户设备感兴趣的 MBMS服务的频率的测量报告被最先发送， 由此可以很 好地保证 MBMS服务的连续性。
