Description

技术领域
本发明实施例涉及通信技术, 尤其涉及一种小区测量方法及设备。 背景技术
传统的通用移动通信系统 (Universal Mobile Telecommunications System, 简称为 UMTS ) 的码片速率是 3.84兆赫兹 (MHz) , 单载波 UMTS系统部 署在 5MHz 频率带宽上。 在第三代合作伙伴计划 (The 3rd Generation Partnership Project, 简称为 3GPP)的 RP58#会议上通过了设立 S-UMTS的研 究课题, 该课题的研究目的是怎样利用小于 5M带宽或不是 5M带宽整数倍 的连续频谱资源, 也就是说 S-UMTS使用的各种带宽可能不再是 5M带宽。
S-UMTS包含两种载波模式, 一种是非独立(non-standalone)载波模式, 简称为非独立载波 S-UMTS;—种是独立载波模式,简称为独立载波 S-UMTS。 非独立载波模式下的非独立载波不需要提供小区同歩和接入, 独立载波需要 提供小区同歩和接入。在同时包括传统 UMTS和 S-UMTS的网络中, 当用户 设备(User Equipment, 简称为 UE)需要在接入传统 UMTS后, 想要切换到 独立载波 S-UMTS时, 需要对独立载波 S-UMTS进行测量并上报测量结果, 网络侧基于 UE上报的测量结果为 UE选择需要切换到的 S-UMTS频率。 现 有技术存在异频测量和异系统测量两种方法, 但是无论基于哪种测量方法的 测量结果来选择需要切换到的 S-UMTS 频率, 都可能存在误差, 无法保证 UE切换到最适合的频率, 例如 UE可以获得更大容量的 UMTS或 S-UMTS 频率或网侧负载更小的 S-UMTS或 S-UMTS频率。 发明内容

图 2为本发明实施例提供的一种 UE的结构示意图;
图 3为本发明实施例提供的另一种 UE的结构示意图; 图 4为本发明实施例提供的又一种 UE的结构示意图。 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作出创造性劳动前提 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为本发明实施例提供的一种小区测量方法的流程图。如图 1所示, 所述方法包括:
101、 接收网络侧发送的测量控制指示, 所述测量控制指示用于指示 待测频率和需要测量的测量量。
当网络侧需要 UE对某个或某些小区进行测量时, 向 UE发送测量控 制指示, 并通过测量控制指示指示 UE需要进行测量的频率和需要测量的 测量量。 而 UE接收网络侧发送的测量控制指示。 其中, 网络侧指示 UE 进行测量的频率即为所述待测频率。 所述待测频率可以是一个或多个。 其 中, 所述待测频率可以包括 UE当前的使用频率 (used frequency ) , 也可 以包括 UE当前未使用的频率 (non-used frequency ) 。 在一可选实施方式 中, 网络侧向 UE发送测量控制指示包括: 网络侧向 UE发送测量控制消 息, 该测量控制消息用于指示所述待测频率和测量量, 即网络侧通过同一 测量控制消息同时向 UE指示所述待测频率和测量量。 在一可选实施方式 中, 网络侧向 UE发送测量控制指示包括: 网络侧向 UE发送第一测量控 制消息, 例如可以是测量指示, 向 UE指示所述待测频率, 并通过向 UE 发送第二测量控制消息向 UE指示需要测量的测量量。
以 UMTS为例,则所述测量量可以是信干噪比(Ec/No),这里的 Ec/No 是指接收信号功率与总接收功率之比, 或者所述测量量还可以是接收信号 码域功率 (Received Signal Code Power, 简称为 RSCP ) 。 例如, 网络侧 可以通过测量控制指示, 指示 UE测量公共导频信道 (Common Pilot Channel, 简称为 CPICH) 的下行 Ec/No。 又例如, 网络侧可以通过测量控 制指示,指示 UE测量 CPICH或者主公共控制物理信道(Primary Common Control Physical Channel, 简称为 P-CCPCH) 的解扩之后的下行 RSCP。
102、 根据所述测量量, 对所述待测频率上的各小区进行测量, 根据 测量结果, 生成所述待测频率对应的质量估计值。
UE接收到网络侧发送的测量控制指示后, 可以对测量控制指示进行 解析, 从而获取所述测量量和待测频率。 在此说明, 如果所述测量控制指 示包括异频测量指示, 则所述测量控制指示中携带有网络侧指示 UE进行 测量的所述 UE当前未使用的频率, 另外对于异频测量指示, UE同时还 需要对当前使用的频率进行测量, 故在该情况下, 所述待测频率包括异频 测量指示中携带的 UE当前未使用的频率和 UE当前使用的频率。 如果测 量控制指示包括异系统测量指示, 则所述测量控制指示中携带有网络侧指 示 UE进行测量的异系统所在的频率, 另外对于异系统测量指示, UE同 时还需要对当前系统使用的频率进行测量, 故在该情况下, 所述待测频率 包括异系统测量指示中携带的待测系统所在的频率和 UE当前系统使用的 频率。
在获取到所述待测频率和所述测量量后, UE根据所述测量量, 对所 述待测频率上的各小区进行测量, 根据各小区的测量结果, 生成所述待测 频率对应的质量估计值。 本发明各实施例中所述质量估计值是以频率为单 位, 是对某个频率对应的通信质量的衡量, 例如某个频率的质量估计值可 以用对该频率对应的各条信道的信道质量的加权平均的结果来表示, 但不 限于此。
103、 对所述质量估计值和 /或测量触发事件的判决门限进行修正。 对网络侧指示 UE进行的测量, 通常会有对应的测量触发事件, 而测 量触发事件都对应一个判决门限, 当 UE的测量结果满足判决门限后, 会 触发 UE向网络侧上报相应的测量触发事件, 该测量触发事件会携带与测 量有关的一些信息, 例如测量结果等。 其中, 针对各个测量触发事件, 网 络侧还会将有关的参数, 例如 UE当前使用频率的加权系数、 当前使用频 率的门限、 当前未使用频率的门限、 当前未使用频率的加权系数等, 发送 给 UE, 以便 UE基于这些参数进行判决。
在本实施例中, UE生成所述待测频率对应的质量估计值后, 并不直 接将质量估计值与判决门限进行比较, 而是考虑待测频率对应带宽的大小 和 /或待测频率上负载的大小等因素对测量触发事件的上报的影响,首先对 质量估计值和 /或测量触发事件的判决门限进行修正。在此说明, 本发明实 施例所述的测量触发事件是指特定的某个测量触发事件, 并且视不同类型 的测量, 会有所不同。
在一可选实施方式中,为了充分考虑待测频率对应带宽的大小和 /或待 测频率上负载的大小等因素的影响, 定义由这些因素决定的待测频率对应 的频率独特偏置。 然后, 基于待测频率对应的频率独特偏置, 对质量估计 值和 /或测量触发事件对应的判决门限进行修正,以消除上述因素对测量触 发事件的上报造成的不良影响。
具体的, 歩骤 103可以包括以下几种修正方式:
UE可以根据所述待测频率对应的第一频率独特偏置, 对所述质量估 计值进行修正, 其中, 决定所述待测频率对应的第一频率独特偏置的大小 的因素包括:所述待测频率对应带宽的大小和 /或所述待测频率上负载的大 小。
和 /或
UE根据所述待测频率对应的第二频率独特偏置, 对所述判决门限进 行修正, 其中, 决定所述待测频率对应的第二频率独特偏置的大小的因素 包括: 所述待测频率对应带宽的大小和 /或所述待测频率上负载的大小。
上述, 所述待测频率对应的第一频率独特偏置和第二频率独特偏置都 属于所述待测频率对应的频率独特偏置, 区别在于在不同的修正方式中取 值会有所不同。
在此说明, UE对质量估计值的修正, 与对判决门限的修正是反向的。 104、 根据修正后的质量估计值和 /或修正后的判决门限, 确定是否上 报所述测量触发事件。
如果在歩骤 103中, UE使用待测频率对应的第一频率独特偏置, 对 质量估计值进行修正, 则 UE可以将修正后的质量估计值与未经修正的判 决门限进行比较, 以确定是否上报所述测量触发事件。
如果在歩骤 103中, UE使用待测频率对应的第二频率独特偏置, 对 测量触发事件对应的判决门限进行修正, 则 UE可以将未经修正的质量估 计值与修正后的判决门限进行比较, 以确定是否上报所述测量触发事件。 如果在歩骤 103中, UE使用待测频率对应的第一频率独特偏置, 对 质量估计值进行修正, 且使用待测频率对应的第二频率独特偏置, 对测量 触发事件对应的判决门限进行修正, 则 UE可以将修正后的质量估计值与 修正后的判决门限进行比较, 以确定是否上报所述测量触发事件。
在本实施例中,由于考虑了待测频率对应的带宽和 /或待测频率上的负 载情况, 来决定测量触发事件的上报, 消除这些因素对测量触发事件的上 报造成的不良影响, 这样当网络侧基于 UE上报的测量触发事件, 为 UE 选择需要切换到的频率时, 可以选择更加合适的频率, 例如可以是容量更 大的频率或负载更小的频率, 解决了现有技术存在的无法为 UE选择更合 适频率的问题。
在此说明, 本实施例提供的小区测量方法不仅可用来进行以小区切换 为目的测量, 也可以用来进行不以切换为目的测量。
在本发明实施例中, 不对网络侧下发的测量量进行限制, 即无论网络 侧下发的是哪种测量量, 都可以采用上述实施例提供的方法进行测量。
在一可选实施方式中, 考虑包括传统 UMTS和 S-UMTS的网络, 贝 lj 在该网络中, 网络侧下发的测量量可能包括信干噪比或 RSCP。 当网络侧 下发的测量量包括 RSCP时, 对 UE来说, 将会从接收功率的角度对不同 带宽的频率进行比较, 由于接收机灵敏度在不同的带宽下是基本相同的, 也就是说, 在相同业务速率的情况下, 为保证接收质量, 使用不同带宽的 接收机需要的最低接收功率不变, 所以当网络侧指示的测量量包括 RSCP 时, 可以选择使用现有的测量方法进行测量, 而不用在上报测量触发事件 之间对频率的质量估计值和 /或判决门限进行修正。基于此,在该实施方式 中, UE在根据网络侧指示的测量量, 对待测频率上的各小区进行测量, 并根据测量结果, 生成所述待测频率对应的质量估计值之前, 可以先确定 所述测量量是包括信干噪比还是包括 RSCP; 如果判断结果是包括信干噪 比, 则采用本发明实施例提供的方法; 如果判断结果是包括 RSCP, 则可 以不用采用本发明实施例提供的方法, 例如可以采用现有方法进行测量。
在上述实施例或实施方式中, UE根据所述待测频率对应的第一频率 独特偏置,对所述质量估计值进行修正, 和 /或根据待测频率对应的第二频 率偏置, 对测量触发事件的判决门限进行修正之前, 需要先获取所述待测 频率对应的第一频率独特偏置和 /或第二频率独特偏置。
一种可选方式为, 所述待测频率对应的频率独特偏置可由 UE自行配 置。 具体的, 网络侧可以预先将网络中存在的各频率以及各频率对应带宽 的大小等信息下发给 UE; UE预先根据网络中各频率对应带宽的大小, 为 各频率配置对应的频率独特偏置。 在该实施方式中, UE仅考虑了各频率 对应带宽的大小这一因素的影响, 则频率对应带宽的大小与频率对应频率 独特偏置之间的关系可以是: 频率对应的带宽越小, 则频率对应的频率独 特偏置的绝对值越大。 在该可选方式中, UE在接收到网络侧下发的测量 控制指示后, 可以从预先为各频率配置的频率独特偏置中, 获取所述待测 频率对应的第一频率独特偏置和 /或第二频率独特偏置。
另一种可选方式为, 网络侧可以在 UE根据待测频率对应的第一频率 独特偏置, 对所述质量估计值进行修正之前, 向 UE发送所述待测频率对 应的第一频率独特偏置, 而 UE则接收网络侧发送的所述待测频率对应的 第一频率独特偏置。 以及, 网络侧可以在 UE根据待测频率对应的第二频 率独特偏置, 对测量触发事件的判决门限进行修正之前, 向 UE发送所述 待测频率对应的第二频率独特偏置, 而 UE则接收网络侧发送的所述待测 频率对应的第二频率独特偏置。 在该可选方式中, 由于待测频率对应的第 一频率独特偏置和 /或第二频率偏置是由网络侧下发的,故在确定待测频率 对应的第一频率独特偏置和 /或第二频率偏置时,可以考虑除待测频率对应 带宽的大小之外的其他的因素, 例如可以考虑待测频率上负载的大小。
基于上述实施例或各可选实施方式, 在一可选实施方式中, 网络侧发 送的测量指示包括异频测量指示, 此时待测频率为多个, 包括 UE当前使 用频率和网络侧下发的 UE当前未使用频率。 基于此, 歩骤 103的一种实 施方式包括: UE根据所述待测频率对应的第一频率独特偏置, 对所述质 量估计值进行修正, 具体的, UE可以根据公式 (1 ) , 对所述质量估计值 进行修正。

F 是频率 对应的第一频率独特偏置。 例如, 当需要测量的频率 上部 署的是传统 UMTS时, 即频率 j'对应的带宽是 5MHz, 则可以将^。 己置 为 0, 当需要测量的频率 j上部署的是伸缩因子为 2的独立载波 S-UMTS 时,此时频率 对应的带宽小于 5MHz,为 2.5MHz,则可以将 配置为 -3 dB 或者 -4dB。
另外, 在网络侧发送的测量控制指示包括异频测量指示的情况下, 歩 骤 103的另一种实施方式包括: UE根据所述待测频率对应的第二频率独 特偏置, 对测量触发事件的判决门限进行修正, 具体的, UE可以根据公 式 (2 ) , 对测量触发事件的判决门限进行修正。

其中, 2^^是所述测量触发事件上报之前所述待测频率中非最优频率 的质量估计值; β 是所述测量触发事件上报之前的所述多个待测频率中 最优频率的质量估计值; 2。是所述测量触发事件的迟滞参数; ^是 所述非最优频率对应的第二频率独特偏置; 是所述最优频率对应的 第二频率独特偏置。 该实施方式针对的是异频测量方法中的 2A事件, 由 于在 2A事件中, 没有对应的判决门限, 故在本实施例中, 将 2A事件中 的判决门限理解为 0,在 0的基础上进行修正,即直接加上 ^。^或^ ί¾^。 也就是说, F 。^同时也是非最优频率对应的修正后的判决门限,而^ ^ 同时也是所述最优频率对应的修正后的判决门限。
再者,在网络侧发送的测量指示包括异频测量指示的情况下,歩骤 103 的又一种实施方式包括: UE根据所述待测频率对应的第一频率独特偏置, 对质量估计值进行修正, 并根据所述待测频率对应的第二频率独特偏置, 对测量触发事件的判决门限进行修正, 具体的, UE可以根据公式 (1 ) 对 质量估计进行修正, 并根据公式 (2 ) 对测量触发事件的判决门限进行修 正。 在此说明, 在该实施方式中, 公式 (1 ) 中的 F 以及公式 (2 ) 中的

基于上述实施例或各可选实施方式, 在一可选实施方式中, 网络侧发 送的测: 曰 /J包括异系统测量指示, 则待测频率包括当前系统使用的频率 以及网侧下发的待 系统所在的频率。 基于此, 歩骤 103的一种实施方式 包括: UE根据所述待测频率对应的第一频率独特偏置, 对所述质量估计 值进行修正, 具体的, UE可以根据公式 (3 ) , 对所述质量估计值进行修 正。 除此之外, UE也可以根据所述待测频率对应的第二频率独特偏置, 对判决门限进行修正。

在此说明, 本发明实施例提供的方法可用于对任何网络中的频率进行 测量, 尤其适用于对包括多种带宽的网络中的频率进行测量, 例如可以是 包括传统 UMTS和独立载波 S-UMTS的网络。 下面将以包括传统 UMTS 和独立载波 S-UMTS的网络为例,详细说明以下本发明实施例提供的小区 测量方法的原理。
其中, 可以将独立载波 S-UMTS与传统 UMTS之间的测量看作彼此 之间的异频测量, 或者也可以将独立载波 S-UMTS与传统 UMTS之间的 测量看作彼此之间的异系统测量。
在异频测量的场景中, 是将独立载波 S-UMTS与传统 UMTS看作属 于同一系统, 该异频测量可以分为: 相同带宽的异频测量, 即在相同带宽 的不同频率间进行的测量; 和, 不同带宽的异频测量, 即在不同带宽的不 同频率间进行的测量。相同带宽的异频测量包括: 传统 UMTS下不同频率 之间的测量, 以及独立载波 S-UMTS下的相同带宽的不同频率之间的测 量。 不同带宽的异频测量包括: 传统 UMTS下与独立载波 S-UMTS下不 同带宽的频率之间的测量, 以及独立载波 S-UMTS下不同带宽的不同频率 之间的测量。
在异系统测量的场景中, 是将独立载波 S-UMTS与传统 UMTS看作 不同的系统。 异系统测量包括独立载波 S-UMTS对传统 UMTS下频率的 测量, 以及传统 UMTS对独立载波 S-UMTS下频率的测量。 除此之外, 其他系统, 例如 LTE或 GSM, 等对独立载波 S-UMTS下和 /或传统 UMTS 下频率的测量也是一种异系统测量场景, 本发明实施例提供的方法同样适 用。
在本实施例中, 假设对不同带宽的频率进行测量时, 网络侧指定的测 量量包括 Ec/No, 从容量的角度对不同带宽的频率进行比较, 根据香农信 道容量公式 C=W*log2(l+S/N), 由于独立载波 S-UMTS使用的带宽 W比 传统 UMTS使用的带宽要小, 为了弥补独立载波 S-UMTS使用的带宽与 传统 UMTS使用的带宽之间的差异, UE可以在进行测量触发事件的上报 判决之前,对各频率对应的质量估计值和 /或判决门限进行修正, 以使得网 络侧能够根据测量触发事件的上报将 UE切换到能获得更大容量的频率 上。
下面以支持独立载波 S-UMTS的 UE希望从传统 UMTS切换到独立载 波 S-UMTS的场景为例, 对本发明实施例提供的方法做进一歩说明, 但不 限于该应用场景。
在上述场景下, 网络侧会向 UE下发异频测量指示, 在异频测量指示中携带 有网络侧指示测量的独立载波 S-UMTS下的频率, 并向 UE发送测量控制消 息, 所述测量控制消息携带有网络侧指示的测量量, 假设所述测量量包括 Ec/No UE接收到异频测量指示后, 从中获取网络侧指示测量的独立载波 S-UMTS 下的频率, 这里所述待测频率包括从异频测量指示中获取的独立载 波 S-UMTS下的频率和 UE当前使用的传统 UMTS下的频率; UE从测量控 制消息中获取所述测量量; 根据所述测量量, 对所述待测频率上的虚拟激活 集中的各小区进行测量, 根据测量结果, 生成所述待测频率上的虚拟激活集 对应的质量估计值。 在本实施例中, 以 UE对质量估计值进行修正为例进行 说明, 则 UE根据公式 (1 ) 对质量估计值进行修正; 然后将修正后的质量估 计值与判决门限 (这里的判决门限是未经修正的判决门限) 进行比较, 以确 定是否触发测量触发事件的上报。
由于 UMTS是做软切换的, 所以在比较不同频率时, 是对各频率的虚 拟激活集中的所有小区的质量之和进行比较的。 UE在当前使用频率的虚 拟激活集就是 UE的激活集, UE当前使用频率是传统 UMTS下的频率。 如果当前使用频率的经过修正后的质量估计值或者未使用频率的经过修 正后的质量估计值满足 2A, 2B , 2C , 2D或 2F的判决条件, 则 UE会触 发相应的异频上报事件。 这里未使用频率是指网络侧指示测量的独立载波
S-UMTS下的频率, 即所述待测频率。
其中, 当最优频率发生变化时, 触发 2A事件; 当当前使用频率的经 过修正的质量估计值低于一定门限, 并且一个未使用频率的经过修正的质 量估计值高于一定门限时, 触发 2B事件; 当一个未使用频率的经过修正 后的质量估计值高于一定门限时, 触发 2C事件; 当当前使用频率的经过 修正后的质量估计值低于一定门限时, 触发 2D事件; 当一个未使用频率 的经过修正后的质量估计值低于一定门限时, 触发 2E事件; 当当前使用 频率的经过修正后的质量估计值高于一定门限时, 触发 2F事件。
例如, 2A事件的判决公式可以为下面的公式 (4)。 2C事件的判决公式 可以为下面的公式 (5 )。
Q ≥ Q + H2 / 2 , Λ
Q 2 ( 5 )
其中, 公式(4 ) 中, 是所述测量触发事件上报之前非最优频率的经
^ 。^修正后的质量估计值; 是所述测量触发事件上报之前最优频率的 经^ ^修正后的质量估计值; 是所述测量触发事件的迟滞参数。公式(5 ) 中, β—是对一个未使用频率的经 修正后的质量估计值, 它在该事 件上报时超过了一个绝对门限; ^ c是该异频测量中用于未使用频率的绝 对门限; 是该测量触发事件的迟滞参数。 是所述未使用频率对应 的频率独特偏置。
另外, UE可以不对独立载波 S-UMTS下的频率的质量估计值进行修正, 即仍旧使用原来的质量估计公式, 而对测量触发事件的判决门限进行修正, 具体的,UE可以在网络侧下发的绝对门限的基础上加上频率独特偏置。其中, UE需要根据频率上部署的带宽的不同, 配置相应的频率独特偏置。 例如, 以 异频测量下的 2A事件为例,则 2A事件的判决公式可以是公式(2)。又例如, 以异频测量下的 2C事件为例,则 2C事件的判决公式可以是下面的公式(6)。
Q + 2 ( )
公式 (6) 中, 是对一个未使用频率的质量估计值, 该质量估计值 是未经修正的质量估计; Τ—' 是该异频测量中用于未使用频率的经 0^^ 修正后的判决门限。 当需要测量的频率上部署的是传统 UMTS 时, 可以将 配置为 0, 当需要测量的频率上部署的是伸缩因子为 2 的独立载波 S-UMTS时, 可以将 ^配置为 3dB或 4dB。
另外, 网络侧除了向 UE发送异频测量指示外,还可以向 UE发送异系统 测量指示, 该测量过程与异系统相类似, 在此不再详述。
综上可见, 通过在对不同带宽的独立载波 S-UMTS下的频率的测量中, 针对不同的带宽对质量估计值或判决门限进行修正之后再判断是否上报测量 触发事件,使得网络侧收到 UE上报的测量触发事件后, 能够将 UE切换到可 以使该 UE获得更大容量的系统频率上。
