Description

无线资源控制信令的传输方法及传输系统
本申请要求于2015年04月09日提交中国专利局，申请号为201510167241.X、发明名称为“无线资源控制信令的传输方法及传输系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域，具体而言，涉及一种无线资源控制信令的传输方法和一种无线资源控制信令的传输系统。
背景技术
随着各种移动应用的发展以及移动终端用户的不断增加，现有无线通信系统如4G LTE、LTE-A系统无法满足用户对高速无线接入的带宽需求；并且在提高接入带宽的同时，如何降低成本也是一个非常重要的因素。而利用WLAN(Wireless Local Area Network，无线局域网)的低成本优势来弥补LTE及其增强技术LTE-A在带宽上的不足是一个非常有前景的方向。
现有的WLAN与蜂窝网络的整合技术主要在3GPP进行定义。3GPP现有方案分两种，一种是在核心网的整合，一种是在RAN(Radio Access Network，无线接入网)层面进行整合。
基于现有的网络架构，将WLAN与LTE进行整合时，RRC连接被终结在宏基站。如图1所示，UE(User Equipment，用户设备)与基站之间的RRC(Radio Resource Control，无线资源控制)信令通过UE与基站之间的Uu接口来实现，这种方案造成的结果是：即使UE与基站之间的业务数据流由WLAN来传输，宏基站仍然要与UE保持RRC连接，以进行RRC信令的传输。
可见，相关技术中提出的WLAN与蜂窝网络的整合技术主要存在以下技术问题：
1)宏基站控制信令开销的问题，由于需要UE与基站之间直接进行RRC信令的传输，因此仍然要使用宏网络的资源。
2)UE能耗的问题，UE的用户面数据传输需要通过WLAN进行，但是 控制信令仍然要与宏基站连接，这就导致UE不必要地维护两个无线电连线的动态信息，无法使蜂窝网络的RAT(Radio Access Type)处于闲置状态来实现省电。
因此，如何能够在实现WLAN与蜂窝网络整合的前提下，减少宏网络的资源开销，降低终端的能耗成为亟待解决的技术问题。
发明内容
本发明正是基于上述技术问题至少之一，提出了一种新的无线资源控制信令的传输方案，解决了相关技术中只能由终端直接与基站进行RRC信令传输的问题，减少了宏网络的资源开销，并且由于终端仅可以维持与无线局域网络接入点之间的连接，因此也降低了终端的能耗。
有鉴于此，本发明提出了一种无线资源控制信令的传输方法，包括：终端和/或基站将无线资源控制信令发送至无线局域网络接入点；所述无线局域网络接入点通过与基站之间设置的无线资源控制信令传输通道将所述终端发送的无线资源控制信令传送至所述基站，和/或所述无线局域网络接入点通过无线电传输方式将所述基站发送的无线资源控制信令传送至所述终端。
在该技术方案中，终端和/或基站通过将无线资源控制信令发送至无线局域网络接入点，以由无线局域网络接入点通过与基站之间的RRC信令传输通道将终端发送的RRC信令传送至基站，和/或由无线局域网络接入点通过无线电传输方式将基站发送的RRC信令传送至终端，使得在无线局域网络与蜂窝网络整合后，RRC信令也可以按照业务数据流的传输方式进行传输，即通过无线局域网络接入点在UE与基站之间进行传输，解决了相关技术中只能由终端直接与基站进行RRC信令传输的问题，减少了宏网络的资源开销，并且由于终端仅可以维持与无线局域网络接入点之间的连接，因此也降低了终端的能耗。优选地，终端和/或基站可以将无线资源控制信令以载荷的方式发送至无线局域网络接入点。

方式二：将所述无线资源控制信令作为所述无线局域网络的用户数据进行传输，并设置所述无线资源控制信令具有大于预设优先级的传输优先级。优选地，可以设置无线资源控制信令具有最高的传输优先级。
在上述技术方案中，优选地，所述终端和/或所述基站在将所述无线资源控制信令发送至所述无线局域网络接入点之前，还包括：将所述无线资源控制信令进行PDCP(Packet Data Convergence Protocol，分组数据聚合协议)处理，或将所述无线资源控制信令进行PDCP和RLC(Radio Link Control，无线链路控制层协议)处理；

以下结合图4详细说明本发明的技术方案。
图4示出了根据本发明的实施例的RRC信令的传输流程示意图。
如图4所示，在上行方向，UE的RRC信令经过PDCP和RLC处理(或仅经过PDCP处理)之后，以有效载荷的方式作为WLAN的数据由UE发送给AP(Access Point，接入点)。由于RRC信令进行了加密和完整性保护，AP无法解读RRC消息的内容，AP在接收到UE通过WLAN数据发送的RRC信令后，将数据经过AP-eNB接口上的RRC tunnel传送给eNB，eNB进行 RLC/PDCP处理后把控制信令交由RRC处理模块。
在下行方向，eNB同样对RRC信令先进行加密和完整性保护(即经过PDCP/RLC处理)后，以有效载荷的方式通过RRC tunnel发给AP，AP经过WLAN radio将信令发给UE。
基于上述的方案，本发明需要在AP和eNB之间引入RRC tunnel，在尽可能减少对WLAN规范进行修改的同时，该RRC tunnel需要借由WLAN的QoS(Quality of Service，服务质量)机制实现控制信令的高优先级和短时延传输。该RRC tunnel可以借由实现配置的IPSec等安全关联实现一定的安全性，提高RRC信令传输的可靠性。具体来说，AP在将RRC信令通过RRC tunnel传送至基站时，可以将RRC信令作为WLAN的控制信令进行传输，或者将RRC信令作为WI-FI的用户数据来进行传输，但应设置RRC信令具有较高的传输优先级。此外，AP在将RRC信令传送至终端时，也可以将RRC信令作为WLAN的控制信令进行传输，或者将RRC信令作为WI-FI的用户数据来进行传输，但也应设置RRC信令具有较高的传输优先级。
为了实现上述方法，eNB和UE需要对现有的SRB(Signalling Radio bearers，信令无线承载)机制进行创新。具体来说，SRB作为逻辑实体是存在的，但是SRB的处理并不占用蜂窝网络的无线空口资源。对于基站和UE来说，需要引入新的处理机制。
UE需要引入新的功能，在WLAN link质量符合要求时将将SRB的内容映射到WLAN link，而不是CCCH和DCCH。
UE需要引入新的功能，对WLAN link的链路质量和数据传输质量进行感知。与现有的基于RLF(Radio Link Failure，无线链路失败)机制来实现RRC重建的机制不同，基于WLAN link的RRC连接需要不依赖于RLF的trigger和所定义的一些列timer值，来实现对SRB的可靠传输。举例来说，在WLAN link上RRC信令作为有效载荷传输的信令包，可以通过插入本地序号和强制反馈的方式来实现按序、无丢失的传输。
作为实现上述方法的一部分，UE和eNB仍然需要实时维护UE的context信息以支持宏网络RRC传输的快速恢复能力。换句话说，当WLAN link不可用或需要进行WLAN之间的切换时，RRC信令可以无缝地切换到宏网络的无 线链路上进行传输。即UE与eNB之间的RRC信令的传输可以通过AP来实现传输，也可以直接进行传输。
以上结合附图详细说明了本发明的技术方案，本发明提出了一种新的无线资源控制信令的传输方案，解决了相关技术中只能由终端直接与基站进行RRC信令传输的问题，减少了宏网络的资源开销，并且由于终端仅可以维持与无线局域网络接入点之间的连接，因此也降低了终端的能耗。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
