Description

一种通信方法及装置 技术领域
本发明涉及通信领域，尤其涉及一种通信方法及装置。
背景技术
随着通信技术的发展，终端设备除了有连接态和空闲态两种状态外，还出现了第三态。当终端设备处于连接态时终端设备保存自身的上下文信息，可以执行基于接入网设备控制的切换。当终端设备处于空闲态时终端设备释放自身的上下文信息，可以执行基于小区的重选。当终端设备处于第三态时，终端设备保存其自身的上下文信息并且可以执行基于小区的重选操作，同时，终端设备的连接信息保存在锚点接入网设备，终端设备的连接信息包括终端设备的上下文信息以及核心网连接信息。
在终端设备处于第三态时，终端设备保存一个锚点接入网设备配置的管理区域信息，终端设备移动出该管理区域信息对应的管理区域时需要通知锚点接入网设备。第三态可以叫做非激活态，轻连接态，去激活态，低开销状态等。管理区域也可以叫做寻呼区(Paging Area)，接入网位置跟踪区等。
处于第三态下的终端设备在移动到其他接入网设备的小区需要发送数据时向服务接入网设备发起连接恢复过程，服务接入网设备会通知锚点接入网设备将终端设备的上下文切换到所属服务接入网设备。终端设备每更换一个服务接入网设备，都要执行一次上下文转移和接口切换；每更换一次锚点接入网设备，锚点接入网设备变更都要进行终端设备密钥更新，因此终端设备在移动过程中会产生较多的信令和时延开销。

具体实施方式
本发明实施例涉及的终端设备,可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(例如，Radio Access Network，RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(WLL，Wireless Local Loop)站、个人数字助理(Personal Digital Assistant，PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、终端设备(User Device)、或用户装备(User Equipment)。
本发明实施例所涉及的接入网设备,是指和终端设备进行连接，接收终端设备的数据并发送给核心网(Core Network，CN)的设备。接入网设备在不同的系统对应不同的设备。例如，接入网设备可以是2G系统中的基站(Base Station，BS)和基站控制器(Base Station Controller，BSC)，也可以是3G系统中的基站(Node B)和无线网络控制器(Radio Network Controller，RNC)，还可以是4G系统中的演进型基站(evolutional Node B，eNB或e-Node B)，同样可以是5G系统中对应的接入网设备，本申请并不限定。
图1所示的无线通信系统架构示意图中，终端设备处于第三态，其S1接口锚定在锚点接入网设备，为终端设备配置管理区域，管理区域包括终端设备接入锚点接入网设备的小区和除该小区以外的其他一个或多个小区。终端设备在管理区域内移动不需要向网络侧通知其位置，当移出管理区域时需要向网络侧通知其位置，该过程被称为管理区域更新或者寻呼区更新(Paging Area Update)。在终端设备处于第三态下，终端设备可能位于锚点接入网设备的小区，也可能位于其他接入网设备的小区。
图1的系统架构示意图中还包括核心网CN设备。CN设备在不同的系统对应不同的设备，例如在4G中对应移动管理实体(Mobile Managenment Entity，MME)和或服务网关(Serving GateWay，S-GW)，在3G中对应服务GPRS支持节点(Serving GPRS Support Node，SGSN)，网关GPRS支持节点(Gateway GPRS Support Node，GGSN)等。若处于第三态的终端设备移动到第一接入网设备的服务范围内，则当需要发送数据时，该终端设备向第一接入网设备发起连接恢复过程，第一接入网设备向锚点接入网设备发送终端设备的上下文请求(context request)，并向CN发送路径切换指示，以便把终端设备的S1连接切换到第一接入网设备。
在终端设备的移动过程中，终端设备每更换一个第一接入网设备，都要执行一次上下文转移和接口切换，每更换一次锚点接入网设备，锚点接入网设备的变更都会导致终端设备的密钥更新，因此，终端设备在移动过程中会导致产生较多的信令和时延开销。
鉴于上述技术问题，本发明实施例一方面提供了一种通信方法，如图2所示，该数据传输方法可以应用于图1所示的网络架构，所述方法包括以下步骤：
步骤201：锚点接入网设备向终端设备发送第一消息，该第一消息包含第一标识，所述 第一标识包括用于识别锚点接入网设备的标识和用于在锚点接入网设备内识别所述终端设备的标识。
可选的，该第一消息还包含信道配置索引。所述信道配置索引用以标识所述终端设备在第三态使用的信道配置信息。所述信道配置信息至少包括所述终端设备使用的逻辑信道编号，媒介访问控制(Medium Access Control，MAC)层，无线链路层控制(Radio Link Control，RLC)层配置信息，分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层配置信息的一种。
除此之外，锚点接入网设备还为终端设备配置管理区域。如前所述，终端设备在该管理区域内移动不用通知锚点接入网设备。
步骤202：终端设备向其当前所在小区对应的第一接入网设备发送第一数据传输信息，该第一数据传输信息携带第一标识和上行数据。
在本实施例中终端设备处于第三态，在终端设备处于第三态之前终端设备处于连接态，且在连接态时终端设备所在小区对应的接入网设备为锚点接入网设备。在终端设备由连接态进入第三态时，锚点接入网设备为终端设备配置管理区域，该管理区域包括终端设备接入锚点接入网设备的小区和除该小区以外的其他一个或多个小区。
终端设备向其当前所在小区对应的第一接入网设备发送第一数据传输信息，具体地，终端设备可以将第一标识作为数据包头的一部分，同时携带上行数据发送给第一接入网设备；或者，终端设备可以将第一标识携带在无线资源控制(Radio Resource Control，RRC)消息中，将所述RRC消息连同数据发送给第一无线接入网设备。
在此之前，终端设备需要向基站发送前导序列，所述前导序列用以通知第一接入网设备根据所述前导序列为终端设备分配资源，所述终端设备收到所述资源后，采用所述资源传输所述第一标识以及上行数据。同时，第一无线接入网在分配所述传输资源时会为终端设备分配第二标识。其中，第二标识是基站为终端分配的、使终端设备在当前小区内使用的专用标识。
步骤203：第一接入网设备根据终端设备的信道配置信息对接收到的上行数据进行第一处理。
第一接入网设备收到终端设备发送的第一数据传输信息中的第一标识后，需要将第一标识再次发送给终端设备以便终端设备确定所述第一接入网设备收到了第一标识。终端设备收到该第一标识后，确认第二标识作为自己小区内专用标识使用。
同时，第一接入网设备根据终端设备的信道配置信息对接收到的上行数据进行第一处理，其中，该信道配置信息可以通过以下三种方式获得：
第一种：读取预定义的信道配置信息，例如，第一接入网设备预先设置了第三态终端设备数据传输的预定信道配置信息；
第二种：从终端设备接收信道配置索引，并根据该信道配置索引确定终端设备的信道配置信息。
可选的，锚点接入网设备为终端设备预先配置了信道配置索引，并在步骤201中发送给了终端设备，并且在步骤201b中，第一接入网设备从锚点接入网设备获得了信道配置索引以及信道配置参数，第一接入网设备根据从终端设备收到的信道配置索引确定终端设备使用的信道配置参数。

步骤201b：锚点接入网设备与第一接入网设备之间配置用于进行数据传输的信道配置信息。
可选的，步骤201a和步骤201b可以同时执行或者任意执行其中之一。
可选的，步骤204中，第一接入网设备向锚点接入网设备发送第二数据传输信息通过以下两种方式：
第一种：第一接入网设备利用步骤201a预先建立的公共信道和/或步骤201b预先配置的信道配置信息将第二数据传输信息发送给锚点接入网设备。
步骤201a通过建立的公共信道，使锚点接入网设备和第一接入网设备之间可以进行数据传输。所述锚点接入网设备和第一接入网设备之间的所有第三态终端设备的数据包都可以通过所述公共信道进行传输。
步骤201b中，配置用于第三态终端设备进行数据传输的信道配置信息，包括信道配置参数和索引信息，所述信道配置参数包括所述终端设备使用的逻辑信道编号，MAC层，RLC层配置信息，PDCP层配置信息的至少之一或者其组合。所述索引信息用以指示所述信道配置参数。
第一接入网设备通过预先建立的公共信道和/或预先配置的用于第三态终端设备进行数据传输的信道配置信息，减小了第一接入网设备和锚点接入网设备进行数据传输的传输时延，并且对于终端设备具有通用性，减少了为不同终端建立数据传输的信道和/或信道配置信息，节约了信令资源。
第二种：第一接入网设备向锚点接入网设备发送上下文请求消息，并将第二数据传输信息携带在所述上下文请求消息中发送给锚点接入网设备。
步骤205：锚点接入网设备对收到上行数据进行第二处理。

步骤206：锚点接入网设备发送第二处理后的上行数据给核心网设备。
在由终端设备发起的上行数据传输到核心网设备之后，可选的，核心网设备还可以继续发起下行数据传输。
可选的，步骤207：核心网设备收到第二处理后的上行数据后，发送下行数据给锚点接入网设备。
可选的，步骤208：锚点接入网设备对收到的下行数据进行第三处理。
其中，第三处理与第二处理相类似，包括至少以下之一：MAC层处理、RLC层处理、PDCP层处理，在此不再赘述。
可选的，步骤209：锚点接入网设备向第一接入网设备发送第三数据传输信息。所述第三数据传输信息中携带第一标识和第三处理后的下行数据。
可选的，步骤210：第一接入网设备对收到的下行数据进行第四处理。
其中，第四处理与第一处理相类似，包括以下至少一种：物理层处理、MAC层处理、RLC层处理；且第四处理不包括解密和/或完整性校验，在此不再赘述。

可选的，步骤212：终端设备基于一定的条件，不再监听第二标识，并结束数据传输过程。
可选的，终端设备结束数据传输的过程的条件为：
(1)终端设备收到下行数据后，一段时间内没有再收到下行数据，也没有任何上行数据需要发送；或者
(2)终端设备收到基站发送的释放指示消息，该释放指示消息指示终端设备不再监听第二标识。
在本申请的实施例中，在处于第三态终端设备移动过程中需要与发送数据、与锚点接入网设备和第一接入网设备进行通信时，重新划分了锚点接入网设备和第一接入网设备的功能以及数据传输流程。本申请的实施例通过在数据传输信息中携带包含识别锚点接入网设备的第一标识和数据，使第一接入网设备和锚点接入网设备对接收到的数据分别处理，使终端设备在移动过程中保持锚点接入网设备不变并能够进行数据传输；从而减少了传统方法中因为更换锚点接入网设备而导致终端设备的密钥更新、数据集中处理造成的信令资源浪费；同时，通过预先建立公共信道和/或配置用于第三态终端设备进行数据传输的信道配置信息，减小了第一接入网设备和锚点接入网设备进行数据传输的传输时延，对于终端设备具有通用性，节约了信令资源。
参见图3，图3是本申请实施例提供的另一种通信方法，该方法可以应用于如图1所示的网络架构，该方法包括：
步骤301：与步骤201相同，在此不再详细说明。
步骤302：核心网设备向锚点接入网设备发送下行数据。
步骤303：锚点接入网设备向第一接入网设备发送寻呼消息，
步骤304：第一接入网设备向终端设备发送寻呼消息。
步骤303和304中的寻呼消息都携带指示消息，用以指示所述终端设备是否需要进行状态转换。
因为终端设备在第三态时，在管理区域内移动时并不通知锚点接入网设备，锚点接入网设备不知道终端设备确切在哪个小区，因此一旦核心网设备发送数据，网络侧需要知道终端设备的具体位置，锚点接入网设备必须先在管理区域内发送寻呼给终端设备，然后第一接入网设备发送寻呼给终端设备。终端设备收到寻呼后，会从当前驻留的小区发起寻呼响应，收到寻呼响应的第一接入网设备会通知锚点接入网设备。锚点接入网设备据此可以知道终端设备的确切位置。
步骤305：终端设备根据寻呼消息中携带的指示消息判断是否需要状态转换。
终端设备收到寻呼消息中的指示消息后，如果判断不需要状态转换，则执行下一个步骤；如果判断需要状态转换，向第一接入网设备发送连接恢复消息，以便第一接入网设备为终端设备进行状态转换。
现有技术中终端设备收到的寻呼消息中没有对终端设备的状态是否进行转换的指示信息。本申请的实施例中的上述步骤，通过在寻呼消息中增加用以指示终端设备是否需要进行状态转换的指示信息，使网络侧可以更加灵活地控制终端设备的状态转换。
可选的，步骤306：终端设备向其当前所在小区对应的第一接入网设备发送第一标识。
网络侧向终端设备发送数据，终端设备可以将该第一标识可以携带在恢复连接消息中向网络侧做出响应，该恢复连接消息携带保持终端设备状态不变的指示。该恢复连接消息是终端设备生成的，可以为RRC连接继续消息、RRC连接恢复消息或区域更新消息等。第一标识是锚点接入网设备为终端设备预先分配的，其包括用于识别锚点接入网设备的标识和用于在锚点接入网设备内识别所述终端设备的标识。
可选的，该恢复连接消息同时携带终端设备预先配置的信道信息索引发送给第一接入网设备。或者，该第一标识可以携带在MAC包头或者MAC控制单元中，以便通知第一接入网设备保持终端设备的状态。
在本实施例中终端设备处于第三态，在终端设备处于第三态之前终端设备处于连接态，且在连接态时终端设备所在小区对应的接入网设备为锚点接入网设备。在终端设备由连接态进入第三态时，锚点接入网设备为终端设备配置管理区域，该管理区域包括终端设备接入锚点接入网设备的小区和除该小区以外的其他一个或多个小区。
在此之前，终端设备需要向基站发送前导序列，所述前导序列用以通知第一接入网设备根据所述前导序列为终端设备分配资源，所述终端设备收到所述资源后，采用所述资源传输所述第一标识。同时，第一无线接入网在分配所述传输资源时会为终端设备分配第二标识。其中，第二标识是基站为终端分配的、使终端设备在当前小区内使用的专用标识。
可选的，步骤307：第一接入网设备向锚点接入网设备发送第一标识。
可选的，步骤308：锚点接入网设备判断终端设备是否从第一接入网设备接入，并对核心网设备发送的下行数据进行第一处理。
步骤308中，如果锚点接入网设备判断终端设备是从第一接入网设备接入的，则对核 心网设备发送的下行数据进行第一处理。可选的，第一处理包括以下至少一种：MAC层处理、RLC层处理、PDCP层处理。本步骤中的第一处理与上一实施例中步骤205中的第二处理相类似，在此不再赘述。
可选的，步骤309：锚点接入网设备向第一接入网设备发送第一数据传输信息，所述第一数据传输信息携带第一标识和第一处理后的下行数据。
可选的，在步骤309之前，有两个步骤301a和301b。步骤301a与步骤201a相同，步骤301b与步骤201b相同，在此不再详细说明。
可选的，步骤309中，在锚点接入网设备向第一接入网设备发送第一数据传输信息通过以下两种方式：
第一种：锚点接入网设备利用步骤301a预先建立的公共信道和/或步骤301b预先配置的信道配置信息将第一数据传输信息发送给第一接入网设备。
与本申请上一个实施例相类似的，锚点接入网设备通过预先建立的公共信道和/或预先配置的用于第三态终端设备进行数据传输的信道配置信息，减小了第一接入网设备和锚点接入网设备进行数据传输的传输时延，并且对于终端设备具有通用性，减少了为不同终端建立数据传输的信道和/或信道配置信息，节约了信令资源。
第二种：锚点接入网设备向第一接入网设备发送上下文请求消息，并将第一数据传输信息携带在所述上下文请求消息中发送给第一接入网设备。
可选的，第一数据传输信息还携带终端设备的信道配置索引。
可选的，步骤310：第一接入网设备根据终端设备的信道配置信息对接收到的下行数据进行第二处理。
第一接入网设备收到终端设备发送的第一标识后，需要将第一标识再次发送给终端设备以便终端设备确定所述第一接入网设备收到了第一标识。终端设备收到该第一标识后，确认第二标识作为自己小区内专用标识使用。
同时，第一接入网设备根据终端设备的信道配置对接收到的第一数据传输信息中携带的下行数据进行第二处理，该信道配置通过以下三种方式获得：
第一种：读取预定义的信道配置信息，例如，第一接入网设备预先设置了第三态终端设备数据传输的预定信道配置信息；
第二种：从终端设备接收信道配置索引，并根据该信道配置索引确定终端设备的信道配置信息。
可选的，锚点接入网设备为终端设备预先配置了信道配置索引，并在步骤301中发送给了终端设备，并且在步骤301b中，第一接入网设备从锚点接入网设备获得了信道配置索引以及信道配置参数，第一接入网设备根据从终端设备收到的信道配置索引确定终端设备使用的信道配置参数。
第三种：从锚点接入网设备发送的下行数据包头中获取信道配置信息。
可选的，第二处理包括至少以下之一：物理层处理，MAC层处理，RLC层处理；且所述第二处理不包括解密和/或完整性校验。本步骤中的第二处理与上一实施例中步骤203中的第一处理相类似，在此不再赘述。
可选的，步骤311：第一接入网设备将第二处理后的下行数据发送给终端设备。
至此，网络侧想要发送给终端设备的下行数据通过本申请实施例的方法发送给了终端 设备。如果终端设备有数据要发送给网络侧设备，则可以执行下面的步骤。
可选的，步骤312：终端设备向第一接入网设备发送上行数据。
因为在步骤306中，终端设备已经将第一标识发送给了第一接入网设备和锚点接入网设备，因此，终端设备若想要再次发送上行数据则不需要同时发送第一标识。
可选的，步骤313：第一接入网设备对接收到的上行数据进行第三处理。
其中，第三处理与本实施例中的第二处理相类似，在此不再赘述。
可选的，步骤314：第一接入网设备向锚点接入网设备发送第二数据传输信息，所述第二数据传输信息携带第一标识和第三处理后的上行数据。
可选的，步骤315：锚点接入网设备对接收到的上行数据进行第四处理。
其中，第四处理与本实施例中的第一处理相类似，在此不再赘述。
可选的，步骤316：锚点接入网设备向核心网设备发送第四处理后的上行数据。
可选的，步骤317：与步骤212相同，在此不再详细说明。
在本申请的实施例中，锚点接入网设备和第一接入网设备通过寻呼控制终端设备是否进入状态转换，触发数据上行接入，并在终端设备的上下文切换之前或者同时将数据发送给终端设备。与现有技术相比，增加了网络侧控制终端设备状态转换的灵活性。同时，本申请的该实施例在上一个实施例的基础上，使处于第三态的终端设备在移动过程中保持锚点接入网设备不变并进行数据传输，还避免了传统方法中先转移上下文，再传输数据所带来的信令和时延开销，并对终端设备的数据传输具有通用性。
