Description

一种通信方法、装置及系统 技术领域
本申请涉及但不限于无线通信领域，尤其涉及一种通信方法、装置及系统。
背景技术
随着终端数据业务量膨胀式的增长，让现有的网络资源渐渐力不从心，尤其是在新一代通信技术如第三代移动通信技术(3rd-Generation，3G)、长期演进(Long Term Evolution，LTE)技术等还无法广泛布网的情况下，随之而来的是用户速率和流量需求无法满足，用户体验的变差。如何预防和改变这一情况是运营商必须考虑的问题，一方面需要加快新技术的推广和网络部署；另一方面，希望能够通过对相关网络和技术进行增强，以达到快速提升网络性能的目的。众所周知的，在第三代合作伙伴计划(The 3rd Generation Partnership Project，3GPP)提供的无线网络技术之外，当前已经普遍应用的无线局域网(Wireless Local Area Network，WLAN)，尤其是基于电气和电子工程师学会(Institute of Electrical and Electronics Engineers，IEEE)802.11标准的无线局域网已经在家庭、企业甚至是互联网被广泛应用于热点接入覆盖。其中，由无线保真(Wireless-Fidelity，Wi-Fi)联盟(Alliance)提出的技术规范应用最广，因此，实际中Wi-Fi网络经常跟基于IEEE 802.11标准的WLAN网络划等号，在不引起混淆的情况下，经常采用Wi-Fi模块来描述网络节点中支持WLAN的无线收发和处理模块。
在这一前提下，有的运营商和公司已经提出将WLAN与现有3GPP网络进行融合，实现联合传输，以达到负荷分流和提高网络性能的目的。3GPP SA2版通过了接入网发现和选择功能单元(Access Network Discovery and Selection Functions，ANDSF)方案，提供了一种根据运营商策略为终端选择目标接入网络的模式。
3GPP R10版定义了ANDSF标准，ANDSF作为接入锚点实现智能选网，通过网络与终端的交互协同，实现网络接入的有效分流，符合未来多网协同 的运营方向。ANDSF基于网络负荷、终端能力、用户签约情况等信息制定策略，帮助终端用户选择最佳接入的网络制式，实现多种接入方式的协同运营。ANDSF既可以单独部署，也可与其它网元合设。目前，业界主流观点认为ANDSF可以部署在可编程计算机控制器(Programmable Computer Controller，PCC)设备上。
ANDSF是一个基于核心网的无线局域网互联(WLAN interworking)方案，并没有考虑到对接入网的影响，此外，由于ANDSF是一个相对静态的方案，不能很好对网络负荷与信道质量动态变化的情况进行适应，因此在3GPP接入网组也开展了WLAN interworking讨论。在R12 版WLAN/3GPP无线互操作中，执行WLAN分流的规则和触发的机制被引入。
然而，核心网机制和来自无线接入网的辅助信息机制不能提供给网络侧实时地使用负荷和信道条件，从而合并使用无线资源。另外，来自相同承载的数据不能同时在3GPP和WLAN链路上服务。因此，WLAN与3GPP网络集成的需求在无线接入网(Radio Access Network，RAN)65次全会被重新提出。
相比目前已经研究的依赖于策略和触发的WLAN分流方案，无线接入网层(简称RAN层)聚合的WLAN与3GPP网络集成，简称WLAN和3GPP网络紧耦合，类似于载波聚合和双连接，为总体系统提供更好地双连接上资源的控制和利用。在RAN层的紧集成和聚合允许更多的实时联合调度WLAN与3GPP网络的无线资源，因此能提高用户服务质量(Quality of Service，QoS)和整体系统容量。通过更好管理用户间的无线资源，能增加所有用户的集体吞吐量和提高整个系统容量。基于实时信道条件和系统使用情况下，每个链路调度决定能够做到每一个包的层次。用户面锚定在可靠的LTE网络，可以通过回退到LTE网络来提高性能。
WLAN和3GPP网络紧耦合能应用于同地协作场景(基站(eNB)与无线接入点(Access Point，AP)之间通过内部接口完成RAN层集成操作)和非同地协作场景(eNB与AP之间通过外部接口完成RAN层集成操作)，这个本质上分别类似于3GPP载波聚合和双连接。
对于非同地协作场景，LTE-WLAN融合有外部接口系统架构示意图如图 1所示，eNB与WLAN之间通过外部接口Xw完成RAN层集成操作。这里，首先定义“Wireless LAN Termination”(简称WT，中文名称为“无线局域网终端”)作为LTE-WLAN接口Xw在WLAN系统侧的终结点；WT可以认为是一个逻辑实体，可以是独立网元，也可以在AP/接入控制器(Access Controller，AC)实现。
WT下可连接多个WLAN接入网元，每个WLAN接入网元的状态信息需要告知3GPP系统接入网侧网元。另外，WT逻辑实体上电激活，或者断电去激活，这个不属于某个终端特性的行为，需要建立新的流程以便告知3GPP网络侧，完成3GPP-WLAN紧耦合系统间的WLAN资源配置情况互通。
因此，在3GPP、WLAN融合组网的时候，跨系统场景下如何实现3GPP-WLAN之间WLAN资源配置情况互通的问题需要得到解决。
