Description

一种无线资源控制RRC配置方法及相关设备 技术领域
本发明涉及无线网络技术领域，尤其涉及一种无线资源控制RRC配置方法及相关设备。
背景技术
如图1所示，图1现有技术方案提供的一种UE(User Equipment，用户设备)与eNB(evolved Node B，基站)双联接的架构示意图。在这种架构下，一方面，MCG(Master Cell Group，控制小区组)和SCG(Slave Cell Group，从属小区组)可以保留自己的承载，并向UE提供服务；另一方面，MCG的承载在PDCP(Packet Data Convergence Protocol，分组数据汇聚协议)层进行分流，一部分数据发送给MeNB(主基站)的RLC(Radio Link Control，无线链路控制)层，另一部分经过X2口发送给SeNB(从基站)的RLC层，通过SeNB调度进行发送。
在现有技术方案中，如图2所示，图2是现有技术方案提供的一种双链接的控制示意图。eNB与UE之间的无线连接均是通过MeNB进行发送，当UE与SeNB和MeNB进行双链接通信时，SeNB首先需要根据SCG的负载等情况针对UE进行RRC(Radio Resource Control，无线资源控制)配置，如：UE在SeNB上的RLC层、MAC层等传输配置等，并将RRC配置内容通过X2口发送给MeNB，然后MeNB将MCG以及SCG的RRC配置同时发送给UE，但是在发送过程中，部分RRC配置内容又会继续通过X2口发送给SeNB，通过SeNB发送给UE。由于SeNB的信令经过了2次X2口，会导致SeNB传输延时的增加，另外，如果UE与多个SeNB进行连接，多个SeNB的RRC配置内容都需要经过MeNB进行发送，会导致MeNB的RRC信令负载过大。
发明内容

本文中描述的各种技术可用于各种通信系统，包括2G、3G通信系统和下一代通信系统，例如全球移动通信(GSM，global system for mobile Communication)等2G通信系统，宽带码分多址(WCDMA，wideband code division multiple access)，时分同步码分多址(TD-SCDMA，time division -synchronization code division multiple access)等3G通信系统；长期演进(LTE，long-term evolution)通信系统及其后续演进系统等下一代通信系统。所述基站可以是GSM系统或CDMA系统中的基站收发台(BTS，base transceiver station)、或者WCDMA系统中的节点B(Node B)、或者LTE系统中的演进型节点B(e-NodeB，evolved NodeB)或者LTE后续演进的通信系统中的类似设备。
本发明提供了一种无线资源控制RRC配置方法及相关设备，如图3所示，图3是本发明实施例提供的一种双链接的控制示意图，主要应用于RRC层，用户设备分别与第一基站(MeNB)和第二基站(SeNB)建立RRC连接，第一基站与第二基站之间通过RRC层的X2口建立通信连接，需要说明的是，用户设备还可以与多个SeNB建立RRC连接，以下分别进行详细说明。
请参考图4，图4是本发明第一实施例提出的一种无线资源控制RRC配置方法的流程图。如图所示，本发明实施例中的方法包括：
S401，用户设备接收第一基站发送的RRC配置消息，所述RRC配置消息包括第一RRC配置内容以及信道配置参数。
具体实现中，首先当用户设备与第一基站建立通信连接时，第一基站可以 检查用户设备的业务量是否大于第一预设阈值以及第一基站的负载量是否超过第二预设阈值，当检测到用户设备的业务量大于第一预设阈值或第一基站的负载量超过第二预设阈值时，此时第一基站可以确认用户设备需要配置多连接的通信方式，与N个基站建立RRC连接，其中，N为大于等于2的整数。此时，第一基站可以向用户设备发送RRC配置消息，所述RRC配置消息包括第一RRC配置内容以及信道配置参数，第一RRC配置内容包括第一基站与用户设备之间的多个通信协议层的配置，如，在LTE系统下的PDCP的配置，RLC的配置，MAC层的配置以及物理层的配置等等，信道配置参数可以包括随机接入信道参数、信道带宽参数、物理层反馈信道、物理层控制信道位置等等，用户设备可以使用信道配置参数接入到第二基站。其中，第一基站可以为主基站，第二基站可以为从基站。
S402，所述用户设备响应于所述第一RRC配置内容，对所述用户设备与所述第一基站之间的RRC连接进行配置，并根据所述信道配置参数建立与所述第二基站的RRC连接。
S404，所述用户设备接收所述第二基站发送的第二RRC配置内容。
具体实现中，在用户设备与第二基站建立RRC连接之后，第二基站可以直接将第二RRC配置内容发送给用户设备，因而不需要第二设备先将第二RRC配置内容发送给第一基站，再由第一基站转发给用户设备，在此转发过程中由于分流造成第二RRC配置内容又会重新发送给第二基站，导致传输延时，通过该方法可以减小传输时延，降低第一基站的信令负载。其中，第二RRC配置内容可以包括第二基站与用户设备之间的多个通信协议层的配置，如PDCP的配置，RLC的配置，MAC的配置以及物理层的配置等等。
S404，所述用户设备响应于所述第二RRC配置内容，对所述用户设备与所述第二基站之间的RRC连接进行配置。
在本发明实施例中，用户设备首先接收第一基站发送的RRC配置消息，其中，RRC配置消息包括第一RRC配置内容以及信道配置参数，然后响应于第一RRC配置内容，对用户设备与第一基站之间的RRC连接进行配置，并根据信道配置参数建立与第二基站的RRC连接；其次基于建立的与第二基站的RRC连接接收第二基站发送的第二RRC配置内容；最后响应于第二RRC 配置内容，对用户设备与第二基站之间的RRC连接进行配置，从而可以实现第二基站独立向用户设备发送第二基站的RRC配置内容而不需要第一基站向用户设备发送第二基站的RRC配置内容，不仅减少了基站之间的传输时延，而且降低了第一基站的信令负载。
请参考图5，图5是本发明第二实施例提出的一种无线资源控制RRC配置方法的流程图。如图所示，本发明实施例中的方法包括：
S501，第一基站向用户设备发送RRC配置消息，所述RRC配置消息包括第一RRC配置内容以及信道配置参数。
具体实现中，首先当用户设备与第一基站建立通信连接时，第一基站可以检查用户设备的业务量是否大于第一预设阈值以及第一基站的负载量是否超过第二预设阈值，当检测到用户设备的业务量大于第一预设阈值或第一基站的负载量超过第二预设阈值时，此时第一基站可以确认用户设备需要配置多连接的通信方式，与N个基站建立RRC连接，其中，N为大于等于2的整数。此时，第一基站可以向用户设备发送RRC配置消息，所述RRC配置消息包括第一RRC配置内容以及信道配置参数，第一RRC配置内容包括第一基站与用户设备之间的多个通信协议层的配置，如，在LTE系统下的PDCP的配置，RLC的配置，MAC层的配置以及物理层的配置等等，信道配置参数可以包括随机接入信道参数、信道带宽参数、物理层反馈信道、物理层控制信道位置等等，用户设备可以使用信道配置参数接入到第二基站。其中，第一基站可以为主基站，第二基站可以为从基站。
S502，用户设备响应于所述第一RRC配置内容，对所述用户设备与所述第一基站之间的RRC连接进行配置，并根据所述信道配置参数建立与所述第二基站的RRC连接。
S503，第二基站向用户设备发送第二RRC配置内容。
具体实现中，在用户设备与第二基站建立RRC连接之后，第二基站可以直接将第二RRC配置内容发送给用户设备，因而不需要第二设备先将第二RRC配置内容发送给第一基站，再由第一基站转发给用户设备，在此转发过程中由于分流造成第二RRC配置内容又会重新发送给第二基站，导致传输延 时，并且降低第一基站的信令负载。其中，第二RRC配置内容可以包括第二基站与用户设备之间的多个通信协议层的配置，如PDCP的配置，RLC的配置，MAC的配置以及物理层的配置等等。
S504，用户设备响应于所述第二RRC配置内容，对所述用户设备与所述第二基站之间的RRC连接进行配置。
S505，当所述用户设备与所述第一基站之间的RRC连接发生无线链路失败时，向所述第二基站发送指示消息。其中，指示消息可以包括RRC信令、MAC层控制单元或物理层指示信息等等。
具体实现中，用户设备按照预设周期检测物理层PDCCH信道的信道质量，并经过平滑计算后递交给RRC层，如果计算得到的平均信道质量低于预设门限值，则用户设备与基站之间的RRC连接发生无线链路失败，如果第一基站(MeNB)与用户设备之间的RRC连接发生无线链路失败，那么用户设备需要执行RRC连接重建流程，选择信道质量好的小区进行随机接入；如果第二基站(SeNB)与用户设备之间的RRC连接发送无线链路失败，那么用户设备可以将链路失败的信息发送给第一基站，由第一基站做相应的处理，如：重新选择基站作为用户设备的从基站，或通知第二基站修改链路配置。以下通过用户设备与第一基站之间的RRC连接发生无线链路失败时来说明具体执行流程。
可选的，在向所述第二基站发送指示消息时，用户设备还可以将信号测量报告发送给第二基站，然后由第二基站将信号测量报告转发给第一基站，其中，信号测量报告包括用户设备所连接的各个基站对应的信号质量。
S506，第二基站将所述指示消息转发给所述第一基站。
S507，第一基站根据所述指示消息选择第三基站作为所述用户设备接入的目标基站。
具体实现中，第一基站在接收到指示信息之后，可以根据用户设备上报的信号测量报告，对用户设备所连接的各个基站对应的信号质量进行比较，选择质量较好的第三基站作为用户设备接入的目标基站。
S508，第一基站向所述第三基站发送重配置请求。
S509，第三基站向所述第一基站发送第三RRC配置内容。
具体实现中，在第三基站接收到重配置请求之后，如果第三基站不允许所述用户设备接入，那么通知第一基站选择其他基站作为用户设备接入的目标基站；如果第三基站允许所述用户设备接入，则将第三RRC配置内容发送给第一基站。其中，第三RRC配置内容包括第三基站与用户设备之间的多个通信协议层的配置，如：PDCP的配置，RLC的配置，MAC层的配置以及物理层的配置等等。
S510，第一基站向所述第二基站发送接入配置信息。其中，接入配置信息包括第三基站对应的小区标识、系统带宽、广播消息以及基本随机接入消息等等。同时，第一基站可以将第三RRC配置内容一起转发给第二基站，由第二基站转发给用户设备。
S511，第二基站将所述接入配置信息转发给用户设备。
S512，用户设备根据所述接入配置信息，建立与所述第三基站的RRC连接。
具体实现中，在用户设备接收到所述接入配置信息之后，用户设备可以取消第一基站作为所述用户设备的主控制承载基站，并删除第一基站与用户设备之间的RRC连接的配置信息，将第三基站作为所述用户设备的主控制承载基站，并响应与所述第三RRC配置内容，对用户设备与第三基站之间的RRC连接进行配置。

在本发明实施例中，首先用户设备发送信号测量报告，第一基站根据所述信号测量报告，在确定所述用户设备需要切换小区时选择所述第二基站作为所述用户设备接入的主基站，并向所述第二基站发送切换请求，第二基站如果允许用户设备将第二基站作为主基站接入，那么向第一基站发送重配置信息；用户设备接收第一基站发送的包含重配置信息的更新请求，最后根据更新请求，将第二基站作为主基站接入所述第二基站。其解决了在用户设备需要切换接入的主基站时，需要断开主基站与用户设备的RRC连接导致不能及时通信的问题，通过该设计方案可以不需要断开主基站与用户设备的RRC连接，进而减少切换时延。
