( Capital Expenditure , Capax ) 和运营成本 ( Operating Expense , Opex ) 都比较低, 因此 Hetnet 受到众多运营商的重视, 是无线网络演进的一个 重要方向。
现有技术中, 当微小区与宏小区同频部署时, 在宏小区和微小区重叠 覆盖的区域, 为了减少对相邻小区的干扰, 用户设备 ( User Equipment , UE ) 可以在软切换区提前将相邻小区加入激活集; 同时, 在激活集中的 小区也可以便于 UE接入, 切换信令开销相对较少。

本申请一实施例提供一种测量控制方法, 如图 1所示, 该方法可以包 括:
101、UE接收控制节点下发的测量配置信息,所述测量配置信息包括: 第一类小区列表、 第一类小区类型、 第二类小区列表、 第二类小区类型、 分层小区结构 HCS优先级、 第一类小区频点或用于评估事件门限的专用 参数。
例如, 测量配置信息可以是宏小区列表, 将宏小区视为第一类小区, 微小区视为第二类小区, 而 UE是可以获知周围各小区的小区类型的。
例如, 事件可以是 la或 lb事件等。 其中, la事件是指小区的信号 质量或信号强度达到或高于一定门限。 lb 事件是指小区的信号质量或信 号强度低于一定门限。
例如, 控制节点可以为: 基站控制器或扁平化基站。 在不同的应用场 景中, 所述测量配置信息可以包括: 第一类小区列表、 第一类小区类型、 第二类小区歹1 J表、第二类小区类型、分层小区结构 ( Hierarchical Cell Structure ,
HCS ) 优先级、 第一类小区频点或用于评估所述事件的专用参数等。
102、 UE检测小区的小区信号质量或信号强度。
其中, UE检测周围小区的小区信号质量或信号强度, 并根据信号质 量或信号强度向控制节点上报事件或测量结果, 例如, 当信号质量或信号 强度高于一定门限, 则向控制节点上报 la事件。 在本申请实施例中不同 的是, UE可以进一步的依据测量配置信息确定是否执行上报; 在本发明 的另一实施例中在上报后不期待激活集更新消息。
例如, UE检测周围小区的信号质量, 其中 UE的服务小区是测量配 置信息所指示的第一类小区 (宏小区), 即使服务小区的信号质量低于 lb 门限, 也不向控制节点上报 lb事件; 当然, 对于测量配置信息所指示的 第二类小区 (微小区), 则正常上报 lb事件。 在本发明的另一实施例中, 测量配置信息所指示的第一类小区 (宏小区) UE在服务小区的信号质量 低于 lb门限时上报 lb事件,但即使一段时间内没有收到网络下发的激活 集更新消息, 也不将服务小区的 lb事件上报转为周期事件上报。
103、 UE根据所述小区信号质量或信号强度和所述测量配置信息, 确 定是否向所述控制节点上报所述第一类小区或第一 HCS优先级小区的事 件或测量结果。 其中,第一 HCS优先级小区可以是 HCS优先级低于一定级别的小区 , 类似的, 第二 HCS优先级小区可以是 HCS优先级高于一定级别的小区。 或者, 第一 HCS优先级小区可以是 UE检测到的相邻小区中按照优先级 由低到高的顺序选取的一定比例的小区, 第二 HCS优先级小区可以是第 一 HCS优先级小区之外的相邻小区, 或者按照优先级由高到低的顺序选 取的一定比例的小区。
例如, UE可以根据测量配置信息指示的第一类小区或第一 HCS优先 级小区,在小区信号质量或信号强度满足事件门限时选择上报或不上报事 件。 在本发明的另一实施例中, UE也可以在小区信号质量或信号强度满 足事件门限时上报事件,但是根据测量配置信息指示的第一类小区或第一 HCS优先级小区, 不期待用于删除第一类小区或第一 HCS优先级小区的 激活集更新消息, 即不将上报事件转为周期性地上报事件。 在本发明的另 一实施例中, UE也可以根据测量配置信息中用于评估门限的专用参数, 采用评估得到的门限进行触发是否上报事件,例如当小区信号质量低于采 用专用参数评估得到的 lb门限时, 触发上报 lb事件。 本申请提供的测量 在本实施例中, 由于测量配置信息的配置, 可以控制对事件或测量结 果的上报。 通过不上报第一类小区的 lb事件、 提高第二类小区的 la事件 门限等措施,提前将第一类小区或第一 HCS优先级小区加入到激活集中, 延緩将第一类小区或第一 HCS优先级小区从激活集中删除, 从而尽量将 第一类小区或第一 HCS优先级小区保留在激活集中, 从而减少 UE切换 到第一类小区或第一 HCS优先级小区所需的切换信令, 避免切换到第一 类小区或第一 HCS优先级小区失败的问题。
可以理解的是, 若 UE确定向控制节点上报事件或测量结果, 则本实 施例的方法还包括后续步骤 104和 105 ; 相反的, 若 UE确定不向控制节 点上报事件或测量结果, 则可以不需要继续执行后续步骤 104和 105。
104、 控制节点接收 U E上报的事件或测量结果。 其中, UE通过 103的决策结果确定是否上报事件或测量结果。
105、 控制节点根据所述事件或测量结果向所述 UE 下发激活集更新 消息。
例如, 控制节点可以在接收到 la事件后, 向 UE下发激活集更新消 息, 将对应的小区加入 UE的激活集。 在本发明的另一实施例中, 控制节 点可以在接收到 lb事件后, 向 UE下发激活集更新消息, 将对应的小区 从 UE 的激活集中删除。 在本发明的另一实施例中, 控制节点可以根据 UE 上报的测量结果, 将信号质量或信号强度低于预定门限的小区从 UE 的激活集中删除, 将信号质量或信号强度高于预定门限的小区加入到 UE 的激活集。
通过本申请实施例提供的测量控制方法,根据测量配置信息和检测到 的小区信号质量或信号强度, 确定是否上报事件或测量结果, 与现有技术 中一概根据小区信号质量或信号强度上报事件或测量结果的方法相比,可 以根据需要控制不上报或延緩上报或提前上报第一类小区的事件或测量 结果, 从而达到延緩将第一类小区从 UE的激活集删除或提前将 UE加入 到激活集的目的, 使得可以减少切换到第一类小区的切换信令开销, 及时 切换到第一类小区, 避免切换失败。
进一步可选的, 在本申请实施例的一种实现方式中, 步骤 103的具体 实现方法可以如下所述。
103a,若激活集中同时存在所述测量配置信息指示的第一类小区和第 二类小区, 则不上报所述第一类小区的 lb事件或不上报第二类小区的 la 事件。
在本实现方式中, 所述测量配置信息可以包括: 第一类小区列表、 第 一类小区类型、 第二类小区列表、 第二类小区类型或 HCS优先级等。 例 如, 测量配置信息可以是宏小区列表, 将宏小区视为第一类小区, 微小区 视为第二类小区, 而 UE是可以获知周围各小区的小区类型的。 这样, 当 UE在宏小区覆盖范围内逐渐靠近微小区时, 微小区信号质量或信号强度 急剧提升, 为宏小区信号质量或信号强度变化趋于平滑, 将会导致宏小区 满足 lb 门限。 因此, 为了尽量保持宏小区在激活集中, 可以不上报宏小 区的 lb事件。
另外, 当第二类小区满足 1A事件时, 不上报第二类小区的 1A事件。 可以延迟 UE加入激活集。
类似的, 若激活集中同时存在所述测量配置信息指示的第一 HCS优 先级小区和第二 HCS优先级小区, 则不上报所述第一 HCS优先级小区的 lb 事件。 通过第二类小区列表也可以同样的区别第一类小区和第二类小 区, 以 HCS优先级作为测量配置信息的话, 则可以预设优先级低于预定 级别的小区作为第一类小区,可以预设优先级高于预定级别的小区作为第 二类小区,本领域技术人员可以不花费创造性劳动指示第一类小区和第二 类小区, 本申请实施例对此不再——详述。
103b, 若所述激活集中仅存在所述测量配置信息指示的第一类小区, 则当所述第一类小区的小区信号质量或信号强度满足 lb门限时, 上报所 述第一类小区的 lb事件, 以便依据控制节点下发的激活集更新消息从激 活集中删除所述小区。
类似的, 若所述激活集中仅存在所述测量配置信息指示的第一 HCS 优先级小区, 则当所述第一 HCS优先级小区的小区信号质量或信号强度 满足 lb门限时, 上报所述第一 HCS优先级小区的 lb事件, 以便依据控 制节点下发的激活集更新消息从激活集中删除所述小区。
其中, UE的激活集中仅存在第一类小区或第一 HCS优先级小区, 即 UE不在第二小区或第二 HCS优先级小区的覆盖范围内,那么为了节省无 线链路资源, 可以在多个第一类小区或第一 HCS优先级小区中选择信号 质量或信号强度较好的小区。 例如, UE的激活集中仅存在两个第一类小 区或第一 HCS优先级小区, 当两个第一类小区或第一 HCS优先级小区中 的任一个满足 lb门限时, 可以上报该小区的 lb事件, 从而使得控制节点 下发删除该小区的激活集更新消息,将信号质量或信号强度低于预定门限 的第一类小区或第一 HCS优先级小区从激活集中删除。 需要说明的是, 对于本实现方式中未描述的情况, 均可按照协议的常规事件上报流程。
可选的, 在本申请实施例的另一种实现方式中, 步骤 103的具体实现 方法也可以如下所述。
103c,若激活集中同时存在所述测量配置信息指示的第一类小区和第 二类小区, 并且最佳小区或服务小区为第二类小区, 则不上报所述第一类 小区的 lb事件。
在本实现方式中, 所述测量配置信息可以包括: 第一类小区列表、 第 一类小区类型、 第二类小区列表、 第二类小区类型或 HCS优先级等。 例 如, 测量配置信息可以是由多个小区标识构成的第一类小区列表, 不在该 列表中的小区则视为第二类小区。 当 UE在第一类小区覆盖内并处于第二 类小区中心(或第二类小区是最佳小区或服务小区)时, 第一类小区的信 号质量或信号强度很容易满足 lb 门限。 但是, 为了避免 UE短时间内离 开第二类小区而进入只有第一类小区覆盖的情形下不能及时切换等问题, 可以不上报该第一类小区的 lb事件, 从而保留第一类小区在激活集中便 于接入。
在另一个实现方式中,若激活集中同时存在所述测量配置信息指示的 第一 HCS优先级小区和第二 HCS优先级小区, 并且最佳小区或服务小区 为第二 HCS优先级小区, 则不上报所述第一 HCS优先级小区的 lb事件。
103d, 若最佳小区或服务小区为所述测量配置信息指示的第一类小 区,则当最佳小区或服务小区之外的第一类小区的小区信号质量或信号强 度满足 lb门限时, 上报所述最佳小区或服务小区之外的第一类小区的 lb 事件。
其中, 如果 UE的激活集中同时有两个或多个第一类小区, 那么不管 激活集中是否存在第二类小区,都可以从多个第一类小区中选择一个信号 质量或信号强度最强的作为最佳小区或服务小区,而上报其他第一类小区 的 lb事件, 将最佳小区或服务小区之外的第一类小区从激活集中删除, 以节约无线链路资源。
在另一实现方式,若最佳小区或服务小区为所述测量配置信息指示的 第一 HCS优先级小区, 则当最佳小区或服务小区之外的第一 HCS优先级 小区的小区信号质量或信号强度满足 lb门限时, 上报所述最佳小区或服 务小区之外的第一 H C S优先级小区的 1 b事件。
通过本申请实施例的上述实现方式中提供的测量控制方法, UE可以 根据测量配置信息指示的第一类小区和第二类小区,在本发明的另一实施 例中根据测量配置信息指示的第一 HCS优先级小区和第二 HCS优先级小 区, 确定是否上报事件或测量结果, 与现有技术中一概根据小区信号质量 或信号强度上报事件或测量结果的方法相比,可以根据需要控制不上报或 延緩上报或提前上报第一类小区或第一 HCS优先级小区的事件或测量结 果, 从而达到延緩将第一类小区或第一 HCS优先级小区从 UE的激活集 删除或提前将 UE加入到激活集的目的, 使得可以减少切换到第一类小区 或第一 HCS优先级小区的切换信令开销, 及时切换到第一类小区或第一 HCS优先级小区, 避免切换失败。
可选的, 在本申请实施例的另一种实现方式中, 步骤 103的具体实现 方法还可以如下所述。
103e、若激活集中同时存在所述测量配置信息指示的第一类小区和第 二类小区, 则第二类小区的测量结果不影响第一类小区的事件评估。
其中, 103a和 103b的实现方式为采用第二类小区的测量结果影响第 一类小区的事件评估, 当满足 lb事件时, 再根据测量配置信息确定是否 上报 lb事件。 而在 103e和 103f 中则在评估第一类小区是否满足 lb事件 时, 不考虑第二类小区的测量结果, 从而使得第一类小区不会因为第二类 小区的信号质量或信号强度较高的影响而导致达到 lb事件。
103f、 若所述激活集中仅存在所述测量配置信息指示的第一类小区, 则当所述第一类小区的小区信号质量或信号强度满足 lb门限时, 采用第 二类小区的测量结果影响第一类小区的事件评估,以便依据控制节点下发 的激活集更新消息从激活集中删除所述小区。
类似的, 步骤 103还可以有以下实现方式。
若激活集中同时存在所述测量配置信息指示的第一 HCS优先级的小 区和第二 HCS优先级的小区, 则第二 HCS优先级的小区的测量结果不影 响第一 HCS优先级小区的事件评估; 在本发明的另一实施例中, 若所述 激活集中仅存在所述测量配置信息指示的第一 HCS优先级小区, 则当所 述第一 HCS优先级小区的小区信号质量或信号强度满足 lb门限时,采用 第二 HCS 优先级的小区的测量结果影响第一 HCS 优先级小区的事件评 估。
在本发明的另一实施例中,若激活集中同时存在所述测量配置信息指 示的第一类小区和第二类小区, 并且最佳小区或服务小区为第二类小区, 则第二类小区的测量结果不影响第一类小区的事件评估;在本发明的另一 实施例中, 若最佳小区或服务小区为所述测量配置信息指示的第一类小 区,则当最佳小区或服务小区之外的第一类小区的小区信号质量或信号强 度满足 lb门限时, 采用第二类小区的测量结果影响第一类小区的事件评 估。
在本发明的另一实施例中,若激活集中同时存在所述测量配置信息指 示的第一 HCS优先级小区和第二 HCS优先级小区, 并且最佳小区或服务 小区为第二 HCS优先级小区, 则第二 HCS优先级的小区的测量结果不影 响第一 HCS优先级小区的事件评估; 在本发明的另一实施例中, 若最佳 小区或服务小区为所述测量配置信息指示的第一 HCS优先级小区, 则当 最佳小区或服务小区之外的第一 HCS优先级小区的小区信号质量或信号 强度满足 lb 门限时, 采用第二 HCS 优先级的小区的测量结果影响第一 HCS优先级小区的事件评估。
通过本申请实施例的上述实现方式中提供的测量控制方法, UE可以 根据测量配置信息指示的第一类小区和第二类小区, 或第一 HCS优先级 小区和第二 HCS优先级小区, 有选择性的采用部分小区的测量结果影响 第一类小区的事件评估, 使得第一类小区或第一 HCS优先级小区不容易 满足 lb事件, 从而达到延緩将第一类小区或第一 HCS优先级小区从 UE 的激活集删除的目的, 使得可以减少切换到第一类小区或第一 HCS优先 级小区的切换信令开销,及时切换到第一类小区或第一 HCS优先级小区, 避免切换失败。
可选的, 在本申请实施例的另一种实现方式中, 步骤 103的具体实现 方法还可以如下所述。
103g、根据所述测量配置信息中的所述用于评估所述事件门限的专用 参数评估事件是否满足, 若满足则触发向所述控制节点上报事件, 以便所 述控制节点根据接收到的所述事件向 UE下发激活集更新消息。
例如,当小区的信号质量或信号强度高于采用所述专用参数评估得到 的 lb门限时, 满足 lb事件。 当小区的信号质量或信号强度低于采用所述 专用参数评估得到的 la门限是, 满足 la事件。
其中,所述测量配置的信息包括所述用于评估所述事件门限的专用参 数。 所述用于评估所述事件门限的专用参数包括: 用于评估所述事件门限 的相对专用偏移量, 或用于评估所述事件门限的绝对专用参数。 网络侧可 以下发个别或一组用于评估所述事件门限的相对专用偏移量, UE将原始 的用于评估事件门限的参数加上偏移量, 可以计算得到新的参数, 采用新 的参数评估事件门限, 触发上报。 在本发明的另一实施例中, 网络侧也可 以下发绝对专用参数, 这样 U E就可以采用新配置的绝对专用参数进行事 件判定。
具体的, 所述用于评估所述事件门限的专用参数, 可以包括以下参数 中的一个或多个: 小区偏移 ( Cell Individal Offset, CIO ), 迟滞、 因子、 报告范围量、 满足事件触发条件的保持时间。 可以在测量配置信息中针对 一个或多个小区、 针对小区类型或针对小区列表下发专用参数, 在实际应 用时可以仅更改其中一个参数, 也可以更改多个参数。
例如, 当 UE在微小区时, 可以给宏小区配置专用的评估参数, 使得 小区设备根据该专用的评估参数计算得到的宏小区的事件门限更低,例如 为宏小区配置更高的 CIO、 更小的迟滞、 更大的因子 (w )、 更大的报告 范围量 (R ) 等, 使得宏小区更早触发 la 事件, 提前加入激活集, 另一 方面更晚触发 lb事件, 延緩离开激活集。 又例如, 当 UE在宏小区时, 可以给微小区配置专用的评估参数使得微小区的专事件门限更高,例如为 微小区配置更低的 CIO、 更大的迟滞、 更小的因子 (W )、 更大的报告范 围量 (R ) 等, 使得微小区更晚触发 la事件, 延緩加入激活集。
通过本申请实施例的上述应用场景中提供的测量控制方法,可以根据 测量配置信息指示的专用参数评估特定小区的事件门限,与现有技术中全 部小区一概采用相同的事件门限相比, 可以根据需要调整事件门限, 从而 达到延緩将第一类小区从 UE的激活集删除或提前将 UE加入到激活集的 目的, 使得可以减少切换到第一类小区的切换信令开销, 及时切换到第一 类小区, 避免切换失败。
可选的, 在本申请实施例的另一种应用场景中, 步骤 103的具体实现 方法还可以如下所述。
103h、 若所述小区是所述测量配置的信息指示的第一类小区或第一 HCS优先级小区, 则向所述控制节点优先上报所述小区的测量结果。
其中, 所述测量配置信息包括: 第一类小区列表、 第一类小区类型、 HCS 优先级或第一类小区频点。 所述小区包括 UE检测到的全部小区, UE可以检测到一个或者多个小区的信号质量或信号强度, 但是由于在本 实施例中 UE在随机接入信道( Random Access Channel, RACH )上上报 测量结果的个数有限,因此按照测量配置信息中指示的规则优先上报第一 类小区或第一 HCS优先级小区的测量结果。 例如, 在 RACH上上报同频 小区测量结果的最大个数为当前小区加上 6个最佳相邻小区,对于异频测 量也仅能最多上报 8个小区的测量结果。 因此, 通过测量配置信息可以规 定上报测量结果的优先顺序, 从而优先上报第一类小区的测量结果, 便于 网络及时进行宏小区分集。 对于同频场景, 可以尽早建立 UE于宏小区的 无线链路; 对于异频场景, 可以提早进行重定向; 从而避免 UE移动而不 能及时切换导致无线链路失败或切换失败的问题。
通过本申请实施例的上述应用场景中提供的测量控制方法,可以根据 测量配置信息指示的第一类小区和第二类小区,有区别的优先上报或推迟 上报测量结果,与现有技术中全部小区一概采用统一的策略上报测量结果 相比, 可以根据需要配置各小区上报测量结果的时序, 从而达到延緩将第 一类小区从 UE的激活集删除或提前将 UE加入到激活集的目的, 使得可 以减少切换到第一类小区的切换信令开销, 及时切换到第一类小区, 避免 切换失败。
本申请另一实施例还提供一种测量控制方法,可以通过专用过滤因子 来调节 UE的测量上报, 如图 2所示。
201、 UE接收控制节点下发的专用过滤因子。
其中, 所述专用过滤因子包括: 过滤因子相对偏移量, 或是新增的绝 对过滤因子。 当收到过滤因子相对偏移量时, 根据初始过滤因子和过滤因 子相对偏移量计算得到的绝对过滤因子。专用过滤因子的下发方式和上述 步骤 103e 中描述的专用参数的下发方式类似, 也可以从网络侧获取新增 的绝对过滤因子作为专用过滤因子。 在本实施例中, 事件采用的过滤因子 和 Id事件采用的过滤因子, 可以相同也可以不同; 例如对于 Id可以不采 用专用过滤因子, 而继续使用现有过滤因子。 其中, Id事件是指 UE的最 佳小区发生变化。
202、 UE检测小区的小区信号质量或信号强度。
203、UE根据所述小区的专用过滤因子和所述小区信号质量或信号强 度计算过滤后的测量结果。
其中,根据最新测量结果和过滤因子计算过滤后的测量结果的过滤公 式形如: Fn= ( 1-a ) Fn_1+aMn。 其中, a=l/2 ( k 2 ), k 是过滤因子, Fn是过 滤后的测量结果, 是历史测量结果, Mn是 UE从物理层接收到的最新 测量结果。 例如, 当最佳小区或服务小区为第一类小区或第一 HCS优先级小区 例如, 当 UE从宏小区进入微小区的覆盖时, 为了平滑切换, 可以提高微 小区的过滤因子使得微小区的信号质量或信号强度緩慢增长,在本发明的 另一实施例中提高宏小区的过滤因子, 使得宏小区的信号緩慢下降, 从而 延迟微小区加入到激活集中。
其中, 当最佳小区或服务小区为第二类小区或高优先级小区时, 网络 当 UE从微小区的覆盖中离开时, 由于微小区的信号质量或信号强度下降 很快, 为了及时切换到宏小区, 可以降低微小区的过滤因子使得微小区的 信号緩慢下降, 提早将宏小区加入到激活集中。
204、 UE根据所述过滤后的测量结果进行事件评估, 若事件满足则向 所述控制节点上报测量结果。
在本实施例中, 对于个别配置了专用过滤因子的小区, UE并不会直 接将检测到的小区信号质量或信号强度作为测量结果上报给控制节点,而 是通过专用过滤因子计算过滤后的测量结果再上报。
205、 控制节点根据收到的测量报告进行激活集更新。
例如, 当测量结果表明激活集中的小区 A的信号质量低于预定门限, 则向 UE下发删除小区 A的激活集更新消息;当测量结果表明不在激活集 中的小区 B的信号质量高于预定门限, 则向 UE下发将小区 B加入到激 活集的激活集更新消息。 在本实施例中, 通过专用过滤因子可以对测量结 果进行平滑处理, 使得小区信号质量或信号强度平滑变化, 从而使得控制 节点可以根据过滤后的测量结果进行激活集更新。
本申请实施例提供的测量控制方法,可以根据各小区的专用过滤因子 有区别的对检测得到的测量结果进行平滑过滤,与现有技术中全部小区一 概采用统一的过滤因子来计算测量结果相比,可以根据需要增快或减慢各 小区测量结果的变化情况, 从而达到延緩将第一类小区从 UE的激活集删 除或提前将 UE加入到激活集的目的,尽量将第一类小区保留在激活集中, 使得可以减少切换到第一类小区的切换信令开销, 及时切换到第一类小 区, 避免切换失败。
本申请另一实施例还提供一种测量控制方法, 如图 3所示, 本实施例 的方法可以如下所述。
301、 UE检测小区信号质量或信号强度。
302、 当小区信号质量或信号强度满足 lb门限时, 控制节点接收 UE 上报的小区的 lb事件。
在本实施例中, 控制节点上配置有测量配置信息, 但是可以不用下发 给 UE, UE正常执行测量和 lb事件上报。
303、 根据测量配置信息和所述 lb事件, 确定是否向所述 UE下发用 于第一类小区或第一 HCS优先级小区的激活集更新消息。
例如, 所述测量配置信息包括: 第一类小区列表、 第一类小区类型、 第二类小区列表、 第二类小区类型、 分层小区结构 HCS优先级、 第一类 小区频点或用于评估事件门限的专用参数。
其中, 所述测量配置信息包括: 第一类小区列表、 第一类小区类型、 第二类小区列表、 第二类小区类型或 HCS优先级。 与步骤 103a、 103b以 及 103c、 103d中描述的测量配置信息类似, 在本实施例中测量配置信息 可以指示第一类小区和第二类小区,在本发明的另一实施例中测量配置信 息可以指示第一 HCS优先级小区和第二 HCS优先级小区。控制节点在接 收到 UE上报的 lb事件后根据测量配置信息指示的第一类小区和第二类 小区决策下发激活集更新小区,在本发明的另一实施例中根据测量配置信 息指示的第一 H C S优先级小区和第二 H C S优先级小区决策下发激活集更 新小区。
进一步可选的, 由于控制节点在接收到 lb事件后不一定会向 UE下 发激活集更新消息, 因此网络也可以预先将测量配置信息发送给 UE, 使 得 UE在上报 lb事件后可以不期待控制节点下发用于删除第一类小区或 第一 HCS优先级小区的激活集更新消息, 即, 即使一段时间内没有收到 激活集更新消息也不将上报 lb事件转为周期性上报 lb事件。 那么, UE 在上报一次某一第一类小区或第一 HCS优先级小区的 lb事件后,在一定 时间段内仍没有收到激活集更新消息,也不会将该第一类小区或第一 HCS 优先级小区的 lb事件转化成周期性发送。
