Description

终端化小区之间的协作方法和系统、终端
本申请要求于2015年03月31日提交中国专利局，申请号为CN201510148682.5、发明名称为“终端化小区之间的协作方法和系统、终端”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，涉及一种终端化小区之间的协作方法、一种终端化小区之间的协作系统和一种终端。
背景技术
目前，随着密集组网的使用，运营商在基础网络投资支出不断增大，运营商利润不断下降，而且密集组网本身的部署也非常困难。5G(Fifth-generation，第五代移动通信技术)网络将支持大量的终端和连接，但在提供更大支持容量的同时，也需要减少对核心网络造成的负荷，以及同时能够支持更加灵活的部署。而现有的小小区(small cell)在应对以上技术挑战方面存在不足，比如：部署的灵活性、部署的成本和应用场景的限制等。因此，业界开始研究基于终端来提供small cell接入的方案，即终端化小区T-SC(Terminal-Small Cell)。
现有small cell方案包括Femtocell(飞蜂窝)、Picocell(主要是为了解决特定区域的室内无线覆盖问题)等。这种方案的实现需要基于有线的backhaul(信号隧道)且需要维护cell(小区)到核心网络一侧的S1、S5接口等。因此，现有small cell方案无法减少终端到核心网络的控制面的连接数量。同时，以这种架构接入到EPC(Evolved Packet Core，演进的分组核心网)，只适用于部署了这些小区的区域，对于网络覆盖不佳以至于无法提供无线覆盖或者无法提供backhaul的区域，或者在移动中的交通工具(且交通工具本身未能提供热点覆盖)上等这些场景下，都无法使用。现有方案还包括MiFi(便携式宽带无线装置)路由器，这种方案基于WLAN(Wireless Local Area Networks，无线局域网)非授权频段，但容易被干扰以至于QoS(Quality of service)难以得到保证。
基于现有技术方案，当多个终端化小区T-SC处于邻近范围内时，小区间的协作若基于传统的X2接口方式(e-NodeB(eNB，演进型基站)之间的互连接口，支持数据和信令的直接传输)进行，则存在冗余路由的问题，并且还需要占用宏网络的无线资源，这对于T-SC之间的协调以及跨T-SC的终端的通信是不利的，如图1所示。
因此，如何实现T-SC小区之间的高效率协作成为目前亟待解决的技术问题。
发明内容
本发明正是基于上述问题，提出了一种新的技术方案，可以实现终端化小区(T-SC)之间的高效率协作，即能够减少终端化小区之间的协作对宏网络无线资源的依赖，以及解决X2接口经过的网元太多而导致的延迟过大的问题。
有鉴于此，本发明的一方面提出了一种终端化小区之间的协作方法，用于建立多个终端化小区之间的协作，包括：确定第一终端化小区和第二终端化小区之间是否建立协作；若所述第一终端化小区和所述第二终端化小区已建立协作，启动所述第一终端化小区和所述第二终端化小区之间的D2D链路的探测过程；在已启动的所述D2D链路的探测过程的所述第一终端化小区和所述第二终端化小区之间建立X2d接口。
在该技术方案中，当确定多个终端化小区中的任意两个终端化小区之间已建立协作时，启动两个终端化小区之间的D2D(Device to Device，设备到设备的通信)链路的探测过程，以及建立两个终端化小区之间的X2d接口，其中，X2d接口是区别于X2接口的基站之间的互连接口，如此，可以实现终端化小区之间的高效率协作，即能够减少终端化小区之间的协作对宏网络无线资源的依赖，以及解决X2接口经过的网元太多而导致的延迟过大的问题。
在该技术方案中，第一终端化小区为多个终端化小区中的任一个终端化小区，第二终端化小区为多个终端化小区中除第一终端化小区外的任一个终端化小区。
在该技术方案中，两个终端化小区之间的D2D链路的探测过程可以采用增强的D2D发现过程和D2D同步机制。
在上述技术方案中，优选地，所述D2D链路的探测过程为双向探测过程。
在该技术方案中，D2D链路的探测过程为双向探测过程，可以有效地确保第一终端化小区和第二终端化小区之间建立的X2d接口是双向可达的，进而实现终端化小区之间的高效率协作。
在上述技术方案中，优选地，所述启动所述第一终端化小区和所述第二终端化小区之间的D2D链路的探测过程，具体包括：分别获取所述第一终端化小区和所述第二终端化小区的链路参数，以启动所述D2D链路的探测过程。
在该技术方案中，需要分别获取第一终端化小区和第二终端化小区用于建立D2D链路所需的链路参数，链路参数可以不完全依赖于预配置，即可以根据实际情况进行实时配置，以满足用户的实时需求，链路参数包括：时频资源、协议处理参数以及是否启动安全处理参数等。
在该技术方案中，如果D2D通信所使用的网络资源与宏网络是同频的，则需要为分布在一个区域的多个终端化小区的不同的两个终端化小区之间分别分配不同的时频资源建立D2D链路，以便于协调D2D链路之间的干扰。
在上述技术方案中，优选地，所述在已启动的所述D2D链路的探测过程的所述第一终端化小区和所述第二终端化小区之间建立X2d接口，具体包括：所述第一终端化小区和所述终端化小区之间协商确定所述X2d接口的TNL(Transport Network Layer)层地址；以及为所述X2d接口上的用于控制信令的所述第一终端化小区侧的所述TNL层地址和所述第二终端化小区侧的所述TNL层地址分别设置终端化小区的终端标识。
在该技术方案中，在具备了链路参数的两个终端化小区之间建立X2d接口，该X2d接口的TNL(Transport Network Layer，传输网络层)层地址可以由两个终端化小区之间协商产生，其中，TNL层地址在格式上可以采用IPv4(Internet Protocol Version 4，第四版互联网协议)或者IPv6(Internet Protocol Version 6，第六版互联网协议)地址，但与相关技术中的在建立X2接口时向相关的网络管理实体申请TNL层地址不同，本技术方案中的TNL层地址只具有本地意义，X2d接口上的用于控制信令的第一终端化小区侧的TNL层地址和第二终端化小区侧的TNL层地址需要使用终端化小区的UE(User Equipment，终端)标识，以及如果X2d接口上要转发数据报文，也需要使用 该终端化小区的终端标识作为下一跳的地址。
