Description

服务小区切换方法及切换设备 技术领域
本发明涉及通讯领域，特别涉及一种服务小区切换方法及切换设备。
背景技术
近年来，全球移动终端用户的数量迅猛发展，对移动终端网络的覆盖范围、服务质量的需求也日益增多。为便于管理以及保证较高的通讯质量，现有的无线通讯网络通常被划分为多个子网，或者多个服务小区。在用户设备(User Equipment，简称UE)移动时，或当前服务小区通讯设备发生故障时，用户设备所处的当前服务小区的通信质量降低，需要从当前服务小区切换到目标服务小区。用户设备是否需要切换服务小区通常依据切换参数来判断。
LTE SON(Long Term Evolution Self Organization Network，长期演进自组织网络)是现有技术中应用最为广泛的一种组网方式，在LTE异频组网的场景下，通常采用A2+A5的切换策略，其中，A2和A5均称为切换测量事件。切换测量事件A2的含义为：服务小区的信号电平低于某一个门限；切换测量事件A5的含义为：服务小区的信号电平低于某一个门限，记为“A5_1”，且异频相邻服务小区的信号电平高于某一个门限，记为“A5_2”。切换测量事件中的各种门限可以称为切换参数。
在LTE异系统组网的场景下，通常会采用A2+B2的切换策略，此时，A2的含义仍为服务小区的信号电平低于某一个门限；B2的含义为：服务小区的信号电平低于某一个门限，记为“B2_1”，且异系统相邻服务小区的信号电平高于某一个门限，记为“B2_2”。B2也称为切换测量事件，其中的门限值称为切换参数。
在服务小区切换过程中，用户设备和当前服务小区的基站仍有数据交互，切换参数的任意一个门限值设置不合理时，都可能会导致当前服务小区通讯质量降低已经无法维持与用户设备的数据交互，迫切需要切换到通讯质量更高的目标服务小区却无法及时的进行切换，即出现服务小区切换过晚事件。可见，服务小区切换过晚可能会导致用户设备切换服务小区失败，会极大的影响用户的使用体验。现有技术中还无法解决服务小区切换过晚的问题。

若发生了无线链路失败(Radio Link failure，简称RLF)事件，根据所述无线链路失败事件前已接收到的所述移动终端上报的切换测量事件，确认导致切换过晚事件的第二切换测量事件的门限。
可选的，根据所述无线链路失败事件前已接收到的所述移动终端上报的切换测量事件，确认导致切换过晚的第二切换测量事件的门限，包括：
若没有接收到所述移动终端上报的所述更新后的第一切换测量事件，则确认所述第二切换测量事件的第二门限值偏小导致切换过晚；
若接收到所述移动终端上报的所述更新后的第一切换测量事件，则确认所述第二切换测量事件的第三门限值偏大导致切换过晚。
本发明实施例中，在出现服务小区切换过晚事件之后，更新第一切换测量事件的第一门限，使第一切换测量事件的第一门限值等于第二切换测量事件的第二门限值。
如果发生了RLF事件，在检测到RLF事件之前，如果没有接收到更新后的第一切换测量事件，由于该更新后的第一切换测量事件的第一门限值等于第二切换测量事件的第二门限值，说明第二切换测量事件的第二门限值设置的是不合理，那么可以确认是第二切换测量事件的第二门限值设置不合理导致的切换过晚，实际此时是第二切换测量事件的第二门限值偏小。
如果发生了RLF事件，在检测到RLF事件之前，已经接收到更新后的第一切换测量事件，由于该更新后的第一切换测量事件的第一门限值等于第二切换测量事件的第二门限值，说明第二切换测量事件的第二门限值设置的是合理，那么可以确认是第二切换测量事件的第三门限值设置不合理导致的切换过晚，实际此时是第二切换测量事件的第二门限值偏大。
本发明实施例的方法，在发生了服务小区切换过晚事件后，通过设置更新后的第一切换测量事件的第一门限，根据发生RLF事件之前已接收到的切换测量事件，可以确认出导致切换过晚的切换参数，从而修正导致切换过晚的切换参数的值，降低再次出现服务小区切换过晚事件的几率，避免出现服务小区切换失败，提高用户的使用体 验，节约运维成本。
可选的，步骤103中，所述修正所述导致切换过晚的切换参数，包括：
若确认所述第二切换测量事件的第二门限值偏小导致切换过晚，则增大所述第二切换测量事件的第二门限值；
若确认所述第二切换测量事件的第三门限值偏大导致切换过晚，则减小所述第二切换测量事件的第三门限值。
本发明实施例的方法，修正导致切换过晚的切换参数的值，可以降低再次出现服务小区切换过晚事件的几率，避免出现服务小区切换失败，提高用户的使用体验，节约运维成本。

步骤202，接收移动终端上报的当前服务小区的A2事件；
步骤203，发送A2更新配置报告至移动终端，使更新后的A2事件的门限值A2_1等于A5事件的门限A5_1的值。
步骤204，检测到RLF事件；
步骤205，判断在检测到RLF事件之前，是否收到了更新后A2事件，若是，则转至步骤206，若否，则转至步骤207。
步骤206，确认A5事件的门限A5_2的值偏大导致切换过晚，减小A5_2的值。
步骤207，确认A5事件的门限A5_1的值偏小导致切换过晚，增大A5_1的值。
