将终端设备重定向到专用网络的方法、终端设备及基站
相关申请的交叉引用
本申请主张在2015年10月13日在中国提交的中国专利申请No.201510670518.0的优先权，其全部内容通过引用包含于此。
技术领域
本公开文本涉及通信技术领域，特别涉及一种将终端设备重定向到专用网络的方法及装置。
背景技术
随着机器型通信(Machine-Type Communication，MTC)的大量使用，网络需要面临大量终端接入到网络的问题，同时不同的终端有不同的特性，支持的业务呈现多样化；例如自动售货机等的MTC设备可能不需要支持移动性，医疗监测等的MTC设备需要保证数据的实时传输，而水表电表等的MTC设备则只需要在特定的时间进行小数据传输等。为了避免这些MTC设备对现有用户的服务造成影响，同时对于不同的用户网络可以为其提供适当的优化服务，运营商可能选择部署不同类型的核心网；因此不同的用户类别的用户设备(User Equipment，UE)将接入到不同的特定网络中。这个特定的网络称之为Décor(专用)网络。
但是在网络部署时，可能存在前期部署的网络由于没有进行升级，而不支持Décor网络特性；或者部署网络时运营商只在部分地方部署了Décor网络的场景。对于这种情况UE就只能接入到非Décor网络中，但若当UE移动到了某一支持Décor特性的位置，或者网络检测到有UE特性的Décor网络的存在，在附着(attach)、跟踪区更新(Tracking Area Update，TAU)或者路由区更新(Routing Area Update，RAU)过程中将会发起如图1所示的网络访问服务器(Network Access Server，NAS)消息重定向过程。
步骤1：当第一个新的移动管理实体(Mobility Management Entity，MME)/服务GPRS支持节点(Serving GPRS(General Packet Radio Service， 通用分组无线服务技术))Support Node，SGSN)收到UE发起的附着请求(attach request)/TAU请求(TAU request)/RAU请求(RAU request)消息后，第一个新的MME/SGSN从旧的MME/SGSN或者归属签约用户服务器(Home Subscriber Server，HSS)中获取UE的UE类型信息。第一个新的MME/SGSN根据UE的UE类型信息以及配置的信息确定是否有满足这一UE需求的Décor网络。
第一个新的MME/SGSN向居民接入网(Residential Access Network，RAN)发送NAS重定向请求，请求中携带完整的NAS消息，同时包含第一个新的MME/SGSN为UE选择的Décor网络的标识信息。在目前的协议中Décor网络是通过MME集团身份(MME Group ID，MMEGI)(演进的UMTS(Universal Mobile Telecommunications System，通用移动通信***)陆地无线接入网(Evolved UMTS Terrestrial Radio Access Network)，E-UTRAN)或者空的网络资源标识符(Null-NRI(Network Resource Identifier)/SGSN Group ID(UMTS陆地无线接入网(UMTS Terrestrial Radio Access Network，UTRAN)/GSM(Global System for Mobile Communication，全球移动通信***)EDGE(Enhanced Data Rate for GSM Evolution，增强型数据速率GSM演进技术)无线接入网(GSM EDGE Radio Access Network，GERAN))来进行标识的。
步骤2：RAN节点的网络节点选择功能基于MMEGI或者Null-NRI/SGSN Group ID为UE选择一个新的MME/SGSN。
步骤3：演进型基站(evolved Node B，eNB)/无线网络控制器(Radio Network Controller，RNC)向选择的MME/SGSN发送初始UE消息(Initial UE message)，其中携带UE的NAS请求信息，以及MMEGI或者Null-NRI/SGSN Group ID信息。MMEGI或者Null-NRI/SGSN Group ID信息指示这是一个重定向的消息。第二个新的MME/SGSN不能将这一NAS消息进行再次重定向。
另外如果UE在源小区时不支持Décor网络，而切换后的新小区支持Décor网络，那么将执行图2中的步骤：
步骤4：当切换后的MME决定要将UE重定向到Décor网络时，MME向UE发起全球唯一临时标识(Globally Unique Temporary Identity，GUTI)重分配过程，其中携带一个没有广播的跟踪区标识(Tracking Area Identity， TAI)/路由区标识(Routing Area Identity，RAI)。
步骤5：MME/SGSN释放RAN侧连接，UE移动到空闲态。
步骤6：没有广播的TAI/RAI触发UE发起TAU过程。MME/SGSN收到TAU/RAU请求消息。
步骤7：MME/SGSN根据图1所示的过程发起NAS重定向过程。
但是相关技术的方案因为考虑到对之前版本终端的兼容，不能对UE的行为有影响，所以最后设计的方案比较复杂。特别是切换后发生重定向，过程更加复杂。相关技术的协议中规定NAS重定向过程只能发生在UE空闲态的TAU/RAU过程中，切换(Hand Over，HO)过程导致的TAU是不能发起NAS重定向的。根据相关技术中的过程，UE发生切换后，若离开了原来的跟踪区域列表(Tracking Area(TA)list)，UE需要在切换过程中发起TAU过程。等这一过程结束后，由MME/SGSN发起GUTI重新分配过程，触发UE再次发起TAU，在这一次的TAU过程中，MME在发起NAS重定向过程。实现复杂，UE和网络中的交互很多。

具体实施方式
下面将结合本公开文一些实施例中的附图，对本公开文一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开文本一部分实施例，而不是全部的实施例。基于本公开文本中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开文本保护的范围。
需要说明的是，本公开文本实施例提供的重定向方法适用于终端设备在源小区不支持与其匹配的专用网络，而切换后的新小区支持与其匹配的专用网络，其切换场景及重定向场景的场景图如图3所示：终端设备从第一基站 切换到第二基站，且该终端设备从第一网络节点切换到第二网络节点，由第二网络节点判断其是否需要进行重定向到专用网络的操作，如果需要则进行本公开文本实施提供的重定向的过程。
如图4所示，本公开文本的一些实施例提供一种将终端设备重定向到专用网络的方法，应用于终端设备，所述终端设备由第一网络节点切换到第二网络节点，所述第一网络节点与第一基站连接，所述第二网络节点与第二基站连接，所述方法包括：
步骤11，接收第二网络节点发送的与所述终端设备匹配的专用网络的标识信息；
步骤12，在所述终端设备回到空闲态后发起跟踪区更新时，将所述专用网络的标识信息发送给所述第二基站，所述专用网络的标识信息用于指示所述第二基站将所述终端设备重定向到与所述标识信息对应的目标网络节点。
在本公开文本的一些实施例中，第一网络节点与第一基站连接，第二网络节点与第二基站连接，且该终端设备从第一基站切换到第二基站，实际上也从第一网络节点切换到第二网络节点。第二网络节点会根据终端设备的签约信息和该第二网络节点的本地配置数据，决定是否需要将终端设备重定向到与该终端设备匹配的专用网络中。若需要将其重定向到专用网络中，则接收第二网络节点发送的相关数据，即该专用网络的标识信息，所述专用网络的标识信息用于指示所述第二基站将所述终端设备重定向到与所述标识信息对应的目标网络节点。
需要说明的是，按照相关技术中的通信机制终端设备回到空闲态后需要一触发条件才能够发起跟踪区更新，则本公开文本实施例提供的方法还包括：
步骤13，接收第二网络节点发送的一触发跟踪区更新的触发信息；所述触发信息用于触发回到空闲态的终端设备发起跟踪区更新。该触发信息是为了触发跟踪区更新的过程的进行，保证终端设备能够重新接入重定向的目标网络节点。
进一步地，本公开文本的上述实施例中所述专用网络的标识信息为MME的组标识或SGSN的组标识中的一个或组合。需要说明的是，上述的标识信息仅为本申请的可选实施例，其他的新定义的标识也适用于本公开文本实施例， 在此不一一列举。具体地，所述触发跟踪区更新的触发信息为非广播的TAI或非广播的RAI。
进一步需要说明的是，其利用触发信息触发跟踪区更新的方法仅为本公开文本的一可选实施例，随着通信技术的不断发展，通过其他方式来触发跟踪区更新或者其终端回到空闲状态会自行触发跟踪区更新等情况也同样属于本申请的保护范围。
需要说明的是，其重定向的过程需在终端设备回到空闲态时才可进行，即在终端设备回到空闲态后，该终端设备根据步骤11中收到的触发信息来触发跟踪区更新，并在其跟踪区更新过程中将专用网络的标识信息发送给第二基站(该第二基站为终端设备当前附着的基站)；第二基站收到其标识信息后，根据所述标识信息确定目标网络节点，并将所述终端设备重定向到上述目标网络节点，完成终端设备的重定向过程。
在本公开文本的一些实施例提供的将终端设备重定向到专用网络的方法中，终端设备获取并保存与终端设备匹配的专用网络的标识信息，继而在终端设备回到空闲态时发起跟踪区更新过程，并将专用网络的标识信息包含在RRC消息中发送给基站，使得基站根据专用网络的标识信息为终端设备选择与专用网络对应的目标网络节点，从而将终端设备重定向至目标网络节点；实现过程简单，且简化了终端设备与网络的交互流程，提高切换效率。
如图5所示，本公开文本的一些实施例提供另一种将终端设备重定向到专用网络的方法，应用于终端设备，所述终端设备由第一网络节点切换到第二网络节点，所述第一网络节点与第一基站连接，所述第二网络节点与第二基站连接，所述方法包括：
步骤21，在所述终端设备切换完成后，接收第二网络节点发送的终端设备的GUTI重分配请求；其中，所述GUTI重分配请求中携带与所述终端设备匹配的专用网络的标识信息；
步骤22，向所述第二网络节点发送GUTI重分配请求响应，所述GUTI重分配请求响应用于表示GUTI重分配是否成功。
步骤23，在所述终端设备回到空闲态后发起跟踪区更新时，将所述专用网络的标识信息发送给所述第二基站，所述专用网络的标识信息用于指示所 述第二基站将所述终端设备重定向到与所述标识信息对应的目标网络节点。
本公开文本的参照图5所述的实施例应用于当终端设备切换完成后，即在GUTI重分配过程中携带专用网络的标识信息。具体地，当切换完成后，第二网络节点MME/SGSN需要将终端设备重定向到专用网络时需发起GUTI重分配过程。此时第二网络节点MME/SGSN在消息中包含专用网络的标识信息。其中，专用网络的标识信息可以是相关技术的协议中的MMEGI或者Null-NRI/SGSN Group ID信息，也可以是新定义的其他标识。而在GUTI重分配过程中携带专用网络标识信息可以是使用单独的IE来传输，也可以是包含在终端设备的GUTI信息中传递给终端设备(即将终端设备的GUTI中的MMEGI或者NRI/SGSN Group ID填为专用网络的MMEGI或者NRI/SGSN Group ID)。完成了GUTI重分配过程后，网络释放终端设备的资源，让终端设备回到空闲态。
进一步地，本公开文本的一些实施例中，步骤23包括：
步骤231，当所述GUTI重分配成功后，接收第二网络节点发送的释放所述终端设备的资源的命令，所述终端设备回到空闲态；
步骤232，发起跟踪区更新，并在向所述第二基站发送的RRC消息中携带与所述终端设备匹配的专用网络的标识信息。
即终端设备收到触发信息后触发跟踪区更新TAU过程，在发送给第二基站的RRC消息中携带专用网络的标识信息，第二基站根据收到的专用网络标识为终端设备选择目标网络节点(MME/SGSN)。
如图6所示，针对图5所示的实施例的具体应用场景进行详细描述：
S1、第二网络节点向终端设备发起GUTI重定向过程，其中携带非广播TAI和MMEGI。非广播TAI用于触发终端发起后续的TAU过程，MMEGI是第二网络节点为终端设备选择的专用网络的标识；
S2、终端设备向第二网络节点发送GUTI重分配请求响应；
S3、终端设备收到后触发TAU过程，在终端设备到第二基站的RRC消息中携带专用网络的MMEGI。其中RRC消息中还包含TAU请求消息；
S4、第二基站根据MMEGI找到专用网络信息，并在专用网络中为终端设备选择目标网络节点；
S5、第二基站将TAU请求消息发送给目标网络节点。
如图7所示，本公开文本的一些实施例提供又一种将终端设备重定向到专用网络的方法，应用于终端设备，所述终端设备由第一网络节点切换到第二网络节点，所述第一网络节点与第一基站连接，所述第二网络节点与第二基站连接，所述方法包括：
步骤31，在所述终端设备切换过程中，向第二网络节点发送跟踪区更新请求；
步骤32，接收所述第二网络节点发送的跟踪区更新请求接收信息，所述跟踪区更新请求接收信息中携带该终端设备与所述终端设备匹配的专用网络的标识信息。
步骤33，在所述终端设备回到空闲态后发起跟踪区更新时，将所述专用网络的标识信息发送给所述第二基站，所述专用网络的标识信息用于指示所述第二基站将所述终端设备重定向到与所述标识信息对应的目标网络节点。
本公开文本的参照图7所述的实施例中，终端设备发生切换后，若终端设备移出了TAI列表，则在切换过程中终端设备就会发起TAU过程。在TAU过程中，第二网络节点MME/SGSN决定将终端设备重定向到专用网络中。此时第二网络节点MME/SGSN在TAU接收消息中包含专用网络的标识信息和没有广播的TAI/RAI值。其中，专用网络的标识信息，可以是相关技术的协议中的MMEGI或者Null-NRI/SGSN Group ID信息，也可以是新定义的其他标识。而在TAU接收消息中携带专用网络标识信息可以是使用单独的IE来传输，也可以是包含在终端设备的GUTI信息中传递给终端设备(即将终端的GUTI中的MMEGI或者NRI/SGSN Group ID填为专用网络的MMEGI或者NRI/SGSN Group ID)。完成TAU过程后，释放UE的资源，UE回到空闲态。
进一步地，在本公开文本的一些实施例中，步骤33包括：
步骤331，完成所述跟踪区更新后，接收第二网络节点发送的释放所述终端设备的资源的命令，所述终端设备回到空闲态；
步骤332，再次发起跟踪区更新，并在向所述第二基站发送的RRC消息中携带与所述终端设备匹配的专用网络的标识信息。
即终端设备保存收到的专用网络的标识信息和没有广播的TAI/RAI值。 并再次触发TAU请求过程。在发送给第二基站的RRC消息中携带专用网络的标识信息，第二基站根据收到的专用网络的标识为终端设备选择专用网络中的目标网络节点(MME/SGSN)。
如图8所示，针对本公开文本的参照图7所述的实施例的具体应用场景进行详细描述：
S6、终端设备发生了从第一网络节点到第二网络节点的切换；
S7、终端设备改变了服务的网络节点，触发TAU过程；
S8、第二网络节点决定将终端设备重定向到专用网络中，在返回的TAU接收消息中包含专用网络的标识MMEGI和没有广播的TAI；
S9、终端设备再次触发TAU过程，在发送给第二基站的RRC消息中携带MMEGI。
S10、第二基站根据MMEGI找到专用网络，并在专用网络中为终端设备选择目标网络节点MME；
S11、第二基站将TAU请求消息发送给目标网络节点。
为了更好的实现上述目的，如图9所示，本公开文本的一些实施例还提供再一种将终端设备重定向到专用网络的方法，应用于第二基站，所述终端设备由第一网络节点切换到第二网络节点，所述第一网络节点与第一基站连接，所述第二网络节点与第二基站连接，所述方法包括：
步骤41，接收终端设备发送的RRC消息，所述RRC消息中包含所述与所述终端设备匹配的专用网络的标识信息；
步骤42，根据所述标识信息，确定与所述标识信息对应的目标网络节点；
步骤43，将所述终端设备重定向到所述目标网络节点。
本公开文本的参照图9所述的实施例中，第二基站为终端设备新接入基站，第二基站接收的RRC消息中包含专用网络的标识信息，则该第二基站能够根据标识信息确定专用网络，从而确定目标网络节点；其中，该目标网络节点和所述第二网络节点均与所述第二基站连接。确定目标网络节点之后，基站则控制终端设备重定向到目标网络节点。
进一步地，本公开文本的一些实施例中步骤43包括：
步骤431，将所述终端设备的初始信息和跟踪区更新请求发送给所述目 标网络节点，控制所述终端设备接入所述目标网络节点。
综上，本公开文本的参照图9所述的实施例中的将终端设备重定向到专用网络的方法中，终端设备获取并保存与终端设备匹配的专用网络的标识信息，继而在终端设备回到空闲态时发起跟踪区更新过程，并将专用网络的标识信息包含在RRC消息中发送给基站，使得基站根据专用网络的标识信息为终端设备选择与专用网络对应的目标网络节点，从而将终端设备重定向至目标网络节点；实现过程简单，且简化了终端设备与网络的交互流程，提高切换效率。
为了更好的实现上述目的，如图10所示，本公开文本一些实施例还提供一种终端设备，所述终端设备由第一网络节点切换到第二网络节点，所述第一网络节点与第一基站连接，所述第二网络节点与第二基站连接，所述装置包括：
