However, the primary CP needs to be changed in some scenarios. When the primary CP cannot be dynamically migrated, the work of the super cell is greatly affected. Here are two typical scenarios:
  • Scenario (1) The device on the primary CP is overloaded, which causes the UE to be blocked. From the perspective of load balancing, you need to switch the CP on another device with a light load as the primary CP. Since there is currently no mechanism for dynamic adjustment of the primary CP, the user can only endure the crowded business experience and may even be disconnected from the network.
  • Scenario (2) The primary CP is retired due to various reasons (for example, the baseband unit is abnormal or the radio unit is abnormal). If the primary CP retreats, the entire super cell will not work. Currently, the commonly used solution is to perform a deletion operation on each CP of the entire super cell. In this way, the UE that has accessed the cell needs to be migrated from the cell, and may even cause the UE to be interrupted, so that the user verification is greatly reduced.

Description

小区主小区点CP迁移的实现方法、装置及系统 技术领域
本发明涉及通信领域，具体而言，涉及一种小区主小区点CP迁移的实现方法、装置及系统。
背景技术
在高铁、航线等高速的移动的场景下，用户设备(user equipment,简称UE)会在小区间进行频繁的切换，对网络的性能冲击和用户的体验都会带来极大的挑战。为了解决这一难题，在相关技术中提出了超级小区的概念。超级小区由多个常规小区组成，每个常规小区覆盖区域简称为一个CP(cell portion，即小区的一部分)，也称为小区点，所有CP共用一个小区标识、主辅同步信号、小区参考信号等信息。图1为相关技术中的超级小区的组网示意图，如图1所示，用户UE在某个超级小区多个CP之间移动，并没有产生小区信息的变化，所以不会存在频繁切换。
在相关技术下，超级小区会选择一个CP作为主CP负责整个超级小区的集中调度，其它CP作为辅CP仅仅负责UE数据的透传，辅CP的数据交由主CP进行统一调度，主CP是超级小区的枢纽，主CP无法工作时，整个超级小区就无法工作。但是主CP在某些场景下需要变更，当无法做到主CP动态迁移时，超级小区的工作就会受到很大影响。以下是两种典型场景：
场景(1)：主CP所在设备负荷过高，会导致UE业务阻塞，从负荷均衡的角度考虑，需要切换另一个负荷较轻的设备上的CP作为主CP。由于目前没有主CP动态调整的机制，用户只能忍受拥挤的业务体验，甚至可能脱网掉话。
场景(2)：由于各种原因导致主CP退服(例如基带单元异常或者射频单元异常等)。如果主CP退服，整个超级小区就无法工作。目前常用的解决方案是对整个超级小区各个CP进行一次删建操作。这样已经接入该小区的UE都要从该小区迁移出去，甚至可能造成UE业务中断，使得用户验证大打折扣。
针对相关技术中，小区主CP设备负荷过重或主CP运行异常导致用户业务中断的问题，目前尚未提出有效的解决方案。

在一种优选的实施例中，在超级小区建立的时候，打破了主辅CP的区分，对各个CP进行同等配置，每个CP随时准备升级为主CP。控制单元负责各CP的配置、主CP的选择以及CP状态的监控等。每个CP有自己的CP参数配置单元、CP状态监测单元和CP状态上报单元，CP参数配置单元负责接收来自控制单元的参数配置和变更，CP状态监测单元负责监控CP的负荷状态和异常状态等，CP状态上报单元将CP的状态信息定时上报给控制单元。图9 示出了控制单元与CP各模块之间的关系示意图。
在超级小区建立过程中，由控制单元根据预定规则(例如为了减小数据交互量，主CP的选取规则可以是在CP数最多的基带单元上选取)选取主CP。然后定时检测每个CP的状态(包括负荷状态和异常状态)，当检测到主CP状态异常需要进行主CP迁移时，控制单元根据规则指定另一个在服的辅CP升为主CP，将主CP的配置信息(如调度参数、物理资源信息等)配给新的主CP，并将正在原主CP上进行的业务，迅速切换到新的主CP上来。

S1003.假设根据S1002所述主CP选取规则，选定CP1为主CP。此时CP2、CP3，CP4都将作为辅CP。同时，控制单元需要保存主CP上的物理资源及调度信息、以及主CP中接入的UE配置信息。
S1004.超级小区建立成功，正常工作。
S1005.控制单元定时检测各CP所在基带单元的负荷情况。
S1006.当发现CP1所在基带单元1的负荷超过一定门限时，控制单元检查基带单元2的负荷情况。当基带单元2的负荷低于某个门限时，决策需要把主CP迁移到基带单元2。假设选出CP3作为新的主CP。
S1007.控制单元发通知消息给CP3使其升为主CP，并将步骤S1003中保存的CP1关键信息配置给CP3。
S1008.CP1变为辅CP，清除CP1上的小区调度信息以及UE相关信息。
S1009.控制单元将主CP的变更通知到CP3、CP4。

S1104.超级小区建立成功，正常工作。
S1105.控制单元定时检测各个CP的状态。
S1106.控制单元检测到CP1硬件或者软件异常，CP1退出服务。
S1107.假设控制单元根据步骤S1102中的规则决策出CP3作为新的主CP。并将步骤S1103中保存的CP1关键信息配置给CP3。
S1108.控制单元将主CP的变更通知到所有在服辅CP(CP2、CP4)。
S1109.整个超级小区恢复正常工作。

    发送单元，用于向所述各个CP发送变更通知消息，其中，所述变更通知消息用于指示所述小区内的所述原主CP变更为所述新的主CP。
  15. 根据权利要求13所述的装置，其中，所述装置还包括：
    通知单元，用于通知所述原主CP清除所述原主CP上的配置信息。
  16. 根据权利要求11至15任一项所述的装置，其中，所述装置还包括：
    保存单元，用于保存所述新的主CP上的配置信息，所述新的主CP上的配置信息包括以下一种或多种信息：物理资源信息，调度信息以及所述新的CP中接入的用户配置信息。
  17. 根据权利要求11所述的装置，其中，所述预设规则包括以下至少之一：
    从CP数量最多的基带单元上处于正常运行状态的辅CP中选取所述新的主CP；
    从负荷小于预定阈值的基带单元上处于正常运行状态的辅CP中选取所述新的主CP；
    直接选择所述小区内CP编号最小的CP作为所述新的主CP。
  18. 一种小区主小区点CP迁移的实现装置，应用于所述CP，包括：
    接收单元，设置为接收所述CP所属的小区内的原主CP的配置信息；其中，所述CP是在所述原主CP的运行状态异常时，按照预设规则从所述小区内的处于正常运行状态的辅CP中选定的CP。
  19. 根据权利要求18所述的装置，其中，所述运行状态异常包括以下至少之一：所述主CP所属基带单元的负荷超过预定阈值、所述主CP硬件异常和所述主CP软件异常。
  20. 根据权利要求18所述的装置，其中，所述配置信息包括以下一种或多种信息：物理资源信息，调度信息以及所述原主CP中接入的用户配置信息。
  21. 一种小区主小区点CP迁移的系统，包括：小区内的控制单元和所述小区内的各个CP；
    其中，所述控制单元，设置为检测所述小区内各个CP的运行状态；以及在检测到所述各个CP中原主CP的运行状态异常时，按照预设规则选定一个处于正常运行状态的辅CP作为新的主CP，将所述原主CP的配置信息配置给所述新的主CP。
  22. 根据权利要求21所述的系统，其中，所述运行状态异常包括以下至少之一：所述主CP所属基带单元的负荷超过预定阈值、所述主CP硬件异常和所述主CP软件异常。
  23. 根据权利要求21所述的系统，其中，所述配置信息包括以下一种或多种信息：物理资源信息，调度信息以及所述原主CP中接入的用户配置信息。
