Description

一种实现负荷分担的方法和装置 技术领域
本文涉及但不限于无线通信技术领域，尤其涉及的是一种实现负荷分担的方法和装置。
背景技术
机器间(Machine to Machine，以下简称M2M)通信是第五代移动通信技术(5G)目前研究的一个重要课题，也是未来无线通信的一个重要应用领域。在M2M课题里，针对低成本低吞吐量类型终端的特性，提出了窄带物联网(NarrowBand-Internet of Things，以下简称NB-IoT)的研究子课题：也就是在200khz的频带内为NB-IoT低成本终端提供低吞吐量的无线通讯服务。
考虑到200khz频谱带宽的单小区容量很小，大量NB-IoT终端接入难免会容量受限，而扩容的简单策略就是多个异频小区覆盖同一区域。目前NB-IoT的多载波组网策略还未确定。而NB-IoT标准一般采用尽可能重用LTE(Long Term Evolution，长期演进)标准及流程等策略。
在LTE网络中，多载波组网时载波间负荷均衡一般有三种策略：载波聚合、重定向、切换。载波聚合方式需要UE(User Equipment，用户设备)同时接收多个载波上的数据，对于低成本低吞吐量的终端来说是不适用的。业务重定向是通过无线资源控制(Radio Resource Control，以下简称RRC)释放消息中指定UE在IDLE(空闲)模式时优选驻留的目标载波，从而实现IDLE模式的多载波负荷分担，由于NB-IoT终端有超低能耗的需求，处于IDLE模式的时间很短，所以该方法对于超低能耗的NB-IoT终端来说是不适用的。切换需要RRC建立完成后通过专门的RRC重配置消息来进行，目前NB-IoT的数据一般有两种传递流程：流程一，通过RRC建立过程中的NAS(Non-access stratum，非接入层)消息进行传递；流程二，通过RRC Resume方式，该流程是为了缩短处理时延而在NB-IoT系统专门引入的信令流程，原理是在业务释放时在网络侧和UE侧保存UE上下文，下次业务建立时通过Resume ID来关联到UE保存的上下文上，节省了新的上下文建立过程，从而 可以减少信令交互。
但是，目前还没有针对NB-IoT多载波负荷分担的具体方案。

示例一
本示例中，小区1和小区2位于同一eNodeB内，且两小区同步、同覆盖。UE在小区1发起RRC连接请求；eNodeB的负荷均衡模块判决需要将UE均衡到小区2中，于是在发送给UE的“RRC连接建立”消息中将“物理小区标识”、“小区频点”信元填写为小区2的“物理小区标识”、“小区频点”值，从而触发了小区1到小区2负荷均衡。

示例五
本示例提供了一种实现负荷分担的系统，该系统包括两类网元：UE、eNodeB。其中，eNodeB包括：第一小区处理模块、第二小区处理模块和负荷均衡模块。UE包括：第一小区收发模块、判断模块和第二小区收发模块。
下面对eNodeB的各个模块进行说明：
第一小区处理模块，设置为管理第一小区(承载UE的当前小区)；
第二小区处理模块，设置为管理第二小区(对第一小区进行负荷均衡的的目标小区)；
负荷均衡模块，设置为执行小区间负荷分担的判决及实施，包括如下四个单元：
小区信息获取单元，设置为获取第一小区和第二小区的负荷信息、小区间是否同覆盖的信息、小区间是否同步的信息，并存储。
负荷均衡判决单元，设置为当UE从第一小区进行RRC连接请求或RRC恢复请求时，接收第一小区处理模块发送的进行负荷均衡判决的通知；根据“小区信息获取单元”存储的第一小区和第二小区的负荷信息判决是否需要 负荷均衡，并将判决结果通知负荷均衡执行单元。
负荷均衡执行单元，设置为如果需要执行负荷均衡且小区间同步，则通知第一小区处理模块在发送给UE的“RRC连接建立”或“RRC连接恢复完成”消息中填写“物理小区标识”、“小区频点”信元；如果需要执行负荷均衡且小区间不同步，则通知第一小区处理模块在发送给UE的“RRC连接建立”或“RRC连接恢复完成”消息中填写“物理小区标识”、“小区频点”、“RACH专用资源或基于竞争的RACH指示”信元。如果无需负荷均衡，则无需在发送给UE的“RRC连接建立”或“RRC连接恢复完成”消息中填写上述信元(“物理小区标识”、“小区频点”、“RACH专用资源或基于竞争的RACH指示”)。当UE从第一小区进行RRC连接恢复请求时，如果需要执行负荷均衡，则需要通知“UE上下文迁移单元”将UE的上下文信息从第一小区迁移到第二小区。
UE上下文迁移单元，设置为在负荷均衡完成后，从第一小区获取UE的上下文信息，并迁移到第二小区。
下面对UE的各个模块进行说明：
第一小区收发模块，设置为接收eNodeB发送的“RRC连接建立”或“RRC连接恢复完成”消息。
判断模块，设置为判断接收到的“RRC连接建立”或“RRC连接恢复完成”消息里是否包含了“物理小区标识”、“小区频点”、“RACH专用资源或基于竞争的RACH指示”信元。如果包含了“物理小区标识”、“小区频点”信元，但没包含“RACH专用资源或基于竞争的RACH指示”信元，则说明发生了负荷均衡，且在第二小区无需发起随机接入；如果包含了“物理小区标识”、“小区频点”和“RACH专用资源或基于竞争的RACH指示”信元，则说明发生了负荷均衡，且需要在第二小区发起随机接入来进行同步。并将判决结果通知“第二小区收发模块”。
第二小区收发模块，设置为根据“判断模块”的判决结果完成小区切换后在第二小区进行后续收发操作。
