Description

一种无线通信的方法和装置 技术领域
本申请涉及通信领域，更具体地，涉及通信领域中一种无线通信的方法和装置。
背景技术
第五代(The fifth generation，5G)移动通信中，在切换(Handover，HO)时延上提出的需求为0ms时延，即，终端设备从源网络设备(或者，源基站)切换至目标网络设备(或者，目标基站)时无传输时间间断。为实现切换过程中的0ms时延，通过为终端设备建立两套栈协议，可以使得终端设备分别与源网络设备和目标网络设备同时通信连接，即，终端设备维持与源网络设备的通信连接，同时与目标网络源网络进行随机接入，使得终端设备分别接收源网络设备和目标网络设备发送的数据。
为了实现HO过程中0ms时延的数据传输，新的无线技术(New Radio，NR)中的HO过程可以通过以下方案实现：针对核心网设备通过同一个S1承载或S1-U承载传输至源网络设备的数据，该源网络设备缓存部分数据，并将剩余数据转发给目标网络设备。其中，该源网络设备与终端设备之间的通路传输该源网络设备缓存的数据，该目标网络设备与该终端设备之间的通路传输由该源网络设备转发给该目标网络设备的数据，从而，在HO过程中，可以使得该终端设备与源网络设备或目标网络设备之间总有数据交互。此外，当该源网络设备不再向该终端设备发送数据，或该源网络设备不再从该终端设备接收数据时，该源网络设备将释放掉与该终端设备对应的协议栈以及数据无线承载，从而停止该终端设备与该源网络设备之间的通信。同理，当该终端设备不再接收该源网络设备发送的数据，或不再向该源网络设备发送数据时，该终端设备也将释放掉与该源网络设备对应的协议栈及数据无线承载，从而停止该终端设备与该源网络设备之间的通信。
然而，在上述HO过程中，若该源网络设备已释放掉与该终端设备对应的协议栈及数据无线承载(此种情况下，该终端设备与该源网络设备也无法通信)，但该终端设备并不知道该源网络设备已释放掉与该终端设备对应的协议栈及数据无线承载，仍在监听信道，以接收该源网络设备发送的数据，也降低了通信过程中的灵活性。
因而，需要提供一种技术，可以使得终端设备或源网络设备能够确定该终端设备与该源网络设备无法通信，从而，可以提高通信过程中的灵活性。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、未来的第五代(5th Generation，5G)系统或新无线(New Radio，NR)等。
本申请实施例中的终端设备可以指用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例对此并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是全球移动通讯(Global System of Mobile communication，GSM)系统或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional NodeB，eNB或eNodeB)，还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
图1是适用本申请实施例的无线通信的方法和装置的通信系统的示意性架构图。如图1所示，该通信系统包括第一网络设备(即，源网络设备或源基站)110、第二网络设备(即，目标网络设备或目标基站)120和终端设备130，该终端设备130分别与该第一网络设备110和该第二网络设备120都通信连接。
具体而言，为了实现该终端设备130与该第一网络设备110和该第二网络设备120之间的通信连接，该终端设备130分别建立与该第一网络设备110和该第二网络设备120之间的栈协议和数据无线承载，从而分别建立与该第一网络设备110和该第二网络设备120之间的通路，可以使得该终端设备130分别接收该第一网络设备110和该第二网络设备120发送的数据。
本申请实施例可以应用于HO场景中，该第一网络设备110是该终端设备130当前所小区的网络设备，该第二网络设备120是该终端设备130切换到的小区的网络设备，当该终端设备130需要从该第一网络设备110切换至该第二网络设备120的过程中，不需要断开该终端设备130与该第一网络设备110的通信连接，继续维持该终端设备130与该第一网络设备110之间的通信连接，并且建立该终端设备130与该第一网络设备110之间的通信连接，从而使得该终端设备130都分别与该第一网络设备110与该第二网络设备120通 信连接。
在HO过程的数据转发方面，针对核心网通过同一个数据无线承载传输至该第一网络设备110的数据，该第一网络设备110缓存部分数据，并将剩余数据转发给该第二网络设备120。其中，该第一网络设备110与终端设备130之间的通路传输该第一网络设备110缓存的数据，该第二网络设备120与该终端设备130之间的通路传输由该第一网络设备110转发给该第二网络设备120的数据，从而，在HO过程中，可以使得该终端设备130与第二网络设备120之间总有数据交互。此外，当该第二网络设备120不再向该终端设备130发送数据，或该第二网络设备120不再从该终端设备130接收数据时，该第二网络设备120将释放掉与该终端设备130对应的协议栈以及数据无线承载。同理，当该终端设备130不再接收该第二网络设备120发送的数据，或不再向该第二网络设备120发送数据时，该终端设备130也将释放掉与该第一网络设备110对应的协议栈和数据无线承载。
作为示例而非限定，本申请实施例不仅可以应用于HO场景中，也可以应用于其他场景中，只要终端设备与至少两个网络设备之间通信连接都可以，例如，本申请实施例也可以应用于双连接(终端设备分别与两个网络设备都通信连接)场景等，本发明实施例并不限于此。
本申请实施例提供了一种无线通信的方法，该方法应用于包括网络设备#A(即，该第一网络设备的一例)、网络设备#B(即，该第二网络设备的一例)和终端设备的通信系统中，该终端设备分别与该网络设备#A和该网络设备#B通信连接，该方法包括：
网络设备向该终端设备发送消息#1(即，第一消息的一例)，该消息#1用于确定该终端设备停止该终端设备与该网络设备#A之间的通信，或，该消息#1用于确定该终端设备释放对应于该网络设备#A的协议栈和数据无线承载，该网络设备为该网络设备#A或该网络设备#B。
具体而言，对于该网络设备#A来说，在确定自己需要停止该终端设备与该网络设备#A之间的通信或可以释放对应于该终端设备的协议栈和数据无线承载时，向该终端设备发送该消息#1，该终端设备在接收到该消息#1后，基于该消息#1，停止与该网络设备#A的通信(例如，不再监听信道等)，或，释放对应于该网络设备#A的协议栈和数据无线承载。
也可以是说，该网络设备#A知道自己需要停止该终端设备与该网络设备#A之间的通信或可以释放对应于该终端设备的协议栈和数据无线承载，导致自己与该终端设备无法通信，为了使得该终端设备也知道自己的行为(或者说，知道自己与该终端设备之间的通信状态)，该网络设备#A通过向该终端设备发送该消息#1，可以使得该终端设备确定自己与该网络设备#A不需要进行通信，从而，停止与该网络设备#A的通信或者释放对应该网络设备#A的协议栈和数据无线承载，可以减少该终端设备由于持续监听信道等造成的功耗以及空口资源的浪费等，有效地提高了通信过程中的灵活性。
对于该网络设备#B来说，在确定该终端设备可以停止该终端设备与该网络设备#A之间的通信或可以释放对应于该网络设备#A的协议栈和数据无线承载时，向该终端设备发送该消息#1，该终端设备在接收到该消息#1后，基于该消息#1，停止与该网络设备#A的通信(例如，不再监听信道等)，或，释放对应于该网络设备#A的协议栈和数据无线承载。
也可以是说，该网络设备#B确定该终端设备与该网络设备#A可以不需要进行通信时， 为了使得该终端设备知道该终端设备后续的行为(或者说，知道该终端设备与该网络设备#A之间的通信状态)，通过向该终端设备发送该消息#1，可以使得该终端设备确定自己与该网络设备#A不需要进行通信，从而，停止与该网络设备#A的通信或者释放对应该网络设备#A的协议栈和数据无线承载，可以减少该终端设备由持续监听信道等造成的功耗以及空口资源的浪费等，有效地提高了通信过程中的灵活性。
因而，本申请实施例提供的无线通信的方法，第一网络设备或第二网络设备在确定该第一网络设备与终端设备不再需要通信时，通过向该终端设备发送第一消息，使得该终端设备基于该第一消息，停止与该第一网络设备之间的通信或释放与该第一网络设备对应的协议栈和数据无线承载，可以减少该终端设备由于持续监听信道等造成的功耗以及空口资源的浪费，有效地提高了通信过程中的灵活性。
此外，在第一网络设备发送该第一消息的情况下，该第一网络设备是知道自己与该终端设备不再需要通信，因此，也会停止与该终端设备的通信或释放对应于该终端设备的协议栈和数据无线承载，减少了该第一网络设备的功耗以及空口资源的浪费，有效地提高了通信过程中的灵活性。
如前所述，当该终端设备与网络设备的传输需要从该网络设备#A切换至该网络设备#B时，该终端设备与该网络设备#B建立连接时，该终端设备与该网络设备#B需要建立新的数据无线承载(为了便于区分与理解，记为数据无线承载#B)，来承载与数据无线承载#A来自核心网设备的同一个S1承载或S1-U承载所承载的数据，以及对应的分组数据汇聚层协议(Packet Data Convergence Protocol，PDCP)和无线链路控制(Radio Link
Control，RLC)协议栈，该终端设备与该网络设备#B之间的数据无线承载#B的ID的配置可以有以下方式：
方式1
该数据无线承载#B采用的ID与该终端设备与该网络设备#A之间的数据无线承载(为了便于区分与理解，记为数据无线承载#A)采用的ID#1是相同的，即，该数据无线承载#B采用的ID为ID#1。
方式2
该数据无线承载#B采用的ID与该数据无线承载#A采用的ID#1相异，该数据无线承载#B采用的ID记为ID#2，且，该数据无线承载#B与该数据无线承载#A之间存在对应关系，该对应关系可以通过网络设备配置，通过信令或协议规定的方式告知该终端设备。
应理解，该数据无线承载#A所承载的数据和该数据无线承载#B所承载的数据都为核心网设备通过同一个S1承载或S1-U承载所承载的数据。
在本申请实施例中，该网络设备#A或该网络设备#B向该终端设备发送该消息#1之前，可以基于不同条件确定该消息#1。下面，分别以该网络设备#A和该网络设备#B作为发送该消息#1的执行主体，结合图2至图3详细说明本申请实施例的无线通信的方法。
首先，以该网络设备#A作为发送该消息#1的执行主体，详细说明本申请实施例的无线通信道的方法。
在发送该消息#1之前，该网络设备#A会基于不同条件确定是否需要与该终端设备继续通信，若是确定自己不需要与该终端设备继续通信，则发送该信息#1。
图2所示为本申请一实施例的无线通信的方法中的该终端设备、该网络设备#A和该 网络设备#B的示意性交互图。
具体而言，如图2所示，在步骤S210中，该网络设备#A执行至少一项步骤，该至少一项步骤做指示的内容作为用于确定发送该消息#1的条件，该至少一项步骤所指示的内容包括：
步骤S211，该网络设备#A接收该终端设备发送的测量报告#1A(即，该第一测量报告中的一例)；
步骤S212，该网络设备#A接收该网络设备#B发送的测量报告#1B(即，该第一测量报告中的另一例)；
步骤S213，该网络设备#A向该终端设备发送该网络设备#A缓存的最后一个数据包；
步骤S214，该网络设备#A停止向该终端设备发送数据包；
步骤S215，该网络设备#A接收该网络设备#B备发送的消息#2(即，该第二消息的一例)。
应理解，该测量报告#1A和该测量报告#1B的功能相同，都是用于指示该终端设备与该网络设备#A之间的信道质量低于阈值，此处使用不同的字母，仅仅是为了区分发送测量报告的发送端设备，不应对本申请实施例构成限定。此外，下文中出现与此处相同的情况，也是为了区分发送测量报告的发送端设备。
还应理解，上述步骤S211至步骤S215的序号并不意味着执行顺序的先后，此处仅仅是为了说明该网络设备#A可能执行的步骤，实现中，可以根据实际情况执行相应的步骤。
具体而言，步骤S211和步骤S212所指示的内容即为该终端设备与该网络设备#A之间的信道质量小于或等于阈值，该阈值可以是预设的该终端设备与该网络设备#A的信道质量的门限值，也可以是该终端设备与该网络设备#B的信道质量与预设值的和，预设值可以通过网络设备配置，通过信令或协议规定的方式告知该终端设备；步骤S213所指示的内容即为该网络设备#A将该网络设备#A缓存的数据包发送完毕，步骤S214所指示的内容即为该网络设备#A不再向该终端设备发送数据包(可以是在步骤S213的情况下不发送数据包，也可以是基于其他情况不发送数据包)，步骤S215所指示的内容即为该信息#2指示该网络设备#A停止与该终端设备的通信或释放对应于该网络设备#A的协议栈和数据无线承载。
从而，在步骤S221中，该网络设备#A可以基于上述至少一个步骤所指示的内容确定该自己可以不需要继续与该终端设备通信，从而，确定该消息#1，指示该终端设备停止与该网络设备#A的通信，或，释放对应的协议栈和数据无线通信，从而，在步骤S222中，发送该消息#1。
需要说明的是，实现过程中，步骤221和步骤222可以合并为一个步骤(即，发送该消息#1)，此处描述的仅仅是逻辑步骤，不应对本申请实施例构成限定。
在步骤S230中，该网络设备#B在发送该消息#1后，停止与该终端设备的通信，或，释放与该终端设备的协议栈和数据无线承载，无论从哪个角度讲，该终端设备与该网络设备#A之间的连接已经断开，从而无法通信。其中，该网络设备#B停止与该终端设备的通信的具体行为可以是不再接收或发送数据包，此外，也可以将释放与该终端设备的协议栈和数据无线承载理解为停止与该终端设备通信的行为。
在步骤S240中，当该终端设备接收到该消息#1后，停止与该网络设备#A的通信， 或，释放对应于该网络设备#A的协议栈和数据无线承载，即，断开与该网络设备#A之间的连接。
在本申请实施例中，可以通过该消息#1中承载的至少一项内容指示该终端设备停止与该网络设备#A的通信，或，释放与该网络设备#A对应的协议栈和数据无线承载：
第一无线资源控制RRC信息；
第一媒体接入控制MAC控制单元CE；
第一数据包，该第一数据包的序列号或计数值与第二数据包的序列号或计数值相同或相邻，该第二数据包由该第二网络设备发送；
第一分组数据汇聚层协议PDCP控制协议数据单元PDU，该第一PDCP控制PDU包括第一编号，该第一编号用于指示该第一网络设备发送的最后一个数据包。
具体而言，该第一RRC信息与该第一MAC CE可以作为显性的信息，例如，该第一RRC信息可以直接指示该终端设备停止与该网络设备#A的通信，释放该网络设备#A对应的协议栈及无线数据承载；该第一MAC CE可以通过报头的逻辑信道指示(Logical Channel Identify，LCID)域指示该终端设备停止与该网络设备#A的通信，或释放与该网络设备#A对应的协议栈及无线数据承载。
该第一MAC CE、该第一数据包与该第一PDCP控制PDU可以作为隐性的信息来指示，该第一MAC CE可以通过报头中的LCID域指示该网络设备#A发送最后一个数据包，该终端设备可以根据该第一MAC CE、第一数据包或该第一PDCP控制PDU确定自己不再需要继续与该网络设备#A的通信，其中，该第一PDCP控制PDU的第一编号是与数据包相关的序列号(Sequence number，SN)或计数(COUNT)值。
在步骤S240中，当该消息#1承载的是该第一RRC信息或该第一MAC CE时，该终端设备可以直接确定自已不再需要继续与该网络设备#A通信，从而，停止与该网络设备#A的通信，或，释放对应于该网络设备#A的协议栈和数据无线承载。
在步骤S240中，当该消息#1承载的是该第一MAC CE时，该终端设备检测到该第一MAC CE后，表示该网络设备#A已经停止向自己发送数据包，则确定自己不再需要继续与该网络设备#A通信，从而停止与该网络设备#A的通信，或，释放对应与该网络设备#A的协议栈和数据无线承载。
在步骤S240中，当该消息#1承载的是该第一数据包时，该终端设备检测到该第一数据包的SN或COUNT值与从该网络设备#B接收到的第一个数据包的SN号或COUNT值相同或相邻，表示该网络设备#A已经将自己缓存的数据包发送完毕，则确定自己不再需要继续与该网络设备#A通信，从而，停止与该网络设备#A的通信，或，释放对应于该网络设备#A的协议栈和数据无线承载。
在步骤S240中，当该消息#1承载的是该第一PDCP控制PDU，该终端设备根据该第一编号，将该第一编号所指示的数据包以及该第一编号所指示的数据包之前的所有数据包都接收后，停止与该网络设备#A的通信，或，释放对应于该网络设备#A的协议栈和数据无线承载。
当该网络设备#A基于上述不同步骤所指示的内容确定该消息#1时，该消息#1所承载的内容可以相同，也可以不同。
例如，当该网络设备#A基于步骤S211所指示的测量报告#1A、步骤S212所指示的 测量报告#1B以及步骤S215所指示的该消息#2发送该消息#1时，该消息#1承载的内容可以是该第一RRC信息和/或该第一MAC CE；
再例如，当该网络设备#A基于步骤S213和步骤S214所指示的内容发送该消息#1时，该消息#1承载的内容可以是该第一数据包和/或该第一PDCP控制PDU，也可以是上述所有的该消息#1可以承载的内容。
应理解，该网络设备#A基于上述不同步骤所指示的内容确定该消息#1的内容仅为示意性说明，不应对本申请实施例构成限定。
在本申请实施例中，该网络设备可以根据接收到的测量报告、该网络设备#A缓存的数据包的多少以及该消息#2等综合确定是否发送该消息#1。注意，此处所描述的测量报告并不是该测量报告#1A和该测量报告#1B所指示的信道质量小于或等于阈值，而是仅仅表示该终端设备与该网络设备#A之间的信道质量，可以是大于阈值，也可以是小于或等于阈值。
例如，一种可选的实施例中，该网络设备#A基于测量报告和该网络设备#A缓存的数据的多少，确定是否发送该消息#1。
具体而言，该网络设备#A首先根据接收到的测量报告确定该终端设备与该网络设备之间的信道质量是否低于阈值：若该信道质量小于或等于该阈值，则发送该消息#1；若该信道质量大于该阈值，则暂时不发送该消息#1，接着，网络设备#A根据该网络设备#A是否缓存有数据包确定是否发送该消息#1：若该网络设备#A缓存有数据包，则不发送该消息#1，该网络设备#A继续维持与该终端设备的通信连接，若该网络设备#A中的数据包已经发送完毕，则发送该消息#1。
再例如，另一种可选的实施例中，该网络设备#A基于该消息#2、测量报告和该网络设备#A缓存的数据的大小，确定是否发送该消息#1。
具体而言，该网络设备#A首先根据是否接收到该消息#2，确定是否发送该消息#1：若该网络设备#A接收到该消息#2，则发送该消息#1；若该网络设备#A未接收到该消息#2，则暂时不发送该消息#1；接着，该网络设备#A根据接收到的测量报告确定该终端设备与该网络设备之间的信道质量是否低于阈值：若该信道质量小于或等于该阈值，则发送该消息#1；若该信道质量大于该阈值，则暂时不发送该消息#1；最后，该网络设备#A根据该网络设备#A是否缓存有数据包确定是否发送该消息#1：若该网络设备#A缓存有数据包，则不发送该消息#1，该网络设备#A继续维持与该终端设备的通信连接，若该网络设备#A中的数据包已经发送完毕，则发送该消息#1。
应理解，上述举例仅为示意性说明，该网络设备#A可以根据上述任意至少两种信息确定是否发送该消息#1，具体根据哪些消息确定发送该消息#1，可以根据实际情况而定，本申请实施例不做任何限定。
需要说明的是，在步骤S215中，该网络设备#A接收该网络设备#B发送的该消息#2，该消息#2可以是该网络设备#B基于该网络设备#A发送的不同消息确定的。
可选地，在该第一网络设备接收该第二网络设备发送的第二消息之前，该方法还包括：
该第一网络设备向该第二网络设备发送第一数据消息，该第一数据消息用于指示该第一网络设备停止向该终端设备发送数据包；或，
该第一网络设备向该第二网络设备发送第二测量报告，该第二测量报告用于指示该终 端设备与该第一网络设备之间的信道质量小于或等于阈值。
对应地，该网络设备#B在接收到该数据消息#1(即，该第一数据消息的一例)和/或该测量报告#2(即，该第二测量报告的一例)后，基于该数据消息#1和该测量报告#2中的至少一个消息生成该消息#2，从而，将该消息#2发送给该网络设备#A，进而，该网络设备#A可以基于该消息#2向该终端设备发送该消息#1。
应理解，该测量报告#2可以是该网络设备#A从该终端设备接收到的测量报告，从而转发给该网络设备#B。
应理解，该测量报告#2与上述的该测量报告#1A和该测量报告#1B的功能相同，都是用于指示该终端设备与该网络设备#A之间的信道质量低于阈值，此处使用不同的阿拉伯数字，仅仅是为了区分发送或接收测量报告的不同情况，不应对本申请实施例构成限定。
此外，下文中出现的多个测量报告，采用阿拉伯数字区分的，也是为了区分发送或接收测量报告的不同情况；同理，下文中出现的多个数据消息，采用阿拉伯数据区分的，是为了区分发送或接收数据信息的不同情况；同理，下文中出现的多个无线链路失败消息，采用阿拉伯数据区分的，是为了区分发送或接收无线链路失败消息的不同情况。下文中出现同类情况的解释同此处，后续不再赘述。
以上，结合图2，以该网络设备#A作为发送该消息#1的执行主体，对本申请实施例的无线通信道的方法进行了详细说明，下面，结合图3，以该网络设备#B作为发送该消息#1的执行主体，详细说明本申请实施例的无线通信道的方法。
图3所示为申请另一实施例的无线通信的方法中的该终端设备、该网络设备#A和该网络设备#B的示意性交互图。
具体而言，如图3所示，在步骤S310中，该网络设备#B执行至少一项步骤(或者说，接收到该终端设备或该网络设备#A发送的各种消息)，该至少一项步骤做指示的内容作为用于确定发送该消息#1的条件，该至少一项步骤所指示的内容包括：
步骤S311，该网络设备#B接收该终端设备发送的测量报告#3A(即，该第三测量报告的一例)，测量报告#3A用于指示该终端设备与该网络设备#A之间的信道质量小于或等于阈值；
步骤S312，该网络设备#B接收该网络设备#A发送的测量报告#3B(即，该第三测量报告的另一例)，该测量报告#3B用于指示该终端设备与该网络设备#A之间的信道质量小于或等于阈值；
步骤S313，该网络设备#B接收该网络设备#A发送的消息#3(即，该第三消息的一例)，该消息#3用于指示该网络设备#A停止该终端设备与该网络设备#A之间的通信，或，该消息#3用于指示该网络设备#A释放对应于该终端设备的协议栈和数据无线承载；
步骤S314，该网络设备#B接收该网络设备#A发送的数据消息#2(即，该第二数据消息的一例)，该数据消息#2用于指示该网络设备#A停止向该终端设备发送数据包；
步骤S315，该网络设备#B接收该终端设备发送的无线链路失败消息#1(即，该第一无线链路失败消息的一例)，无线链路失败消息#1用于指示该终端设备与该网络设备#A发生无线链路失败。
还应理解，上述步骤S311至步骤S315的序号并不意味着执行顺序的先后，此处仅仅是为了说明该网络设备#B可能执行的步骤，实现中，可以根据实际情况执行相应的步骤。
在步骤S313中，该消息#3可以是该网络设备#A基于上文步骤S211至步骤215至少一个步骤所指示的内容确定需要停止该终端设备与该网络设备#A之前的通信后，将该消息#3送给该网络设备#B，该网络设备#B基于该消息#3生成该消息#1，将该消息#1发送给该终端设备。当该网络设备#A与该终端设备之间已经无法通信(例如，信道质量小于或等于阈值时，较差的信道质量使得该终端设备与该网络设备#A不能通信)导致该网络设备#A无法直接发送与该终端停止通信的消息，通过该网络设备#B发送该消息#1，能够提高信息的传输效率。
在步骤S314中，该数据消息#2可以是上文描述的，在该网络设备#A向该终端设备发送该消息#1的情况下，由该网络设备#A发送给该网络设备#B的数据消息#1，用于生成该消息#2；在该网络设备#A未发送该消息#1的情况下，该数据消息#2可以由该网络设备#B用于确定该消息#1的内容，最终由该网络设备#B发送该消息#1。
在步骤S321中，该网络设备#B可以基于上述至少一个步骤所指示的内容确定该终端设备可以不需要继续与该网络设备#A通信，从而，确定该消息#1，进而，在步骤S322中，发送该消息#1。
需要说明的是，实现过程中，步骤321和步骤322可以合并为一个步骤(即，发送该消息#1)，此处描述的仅仅是逻辑步骤，不应对本申请实施例构成限定。
在步骤S330中，当该终端设备接收到该消息#1后，停止与该网络设备#A的通信，或，释放对应于该网络设备#A的协议栈和数据无线承载，即，断开与该网络设备#A之间的连接。
在本申请实施例中，可以通过该消息#1中承载的至少一项内容指示该终端设备停止与该网络设备#A的通信，或，释放与该网络设备#A对应的协议栈和数据无线承载：
第二无线资源控制RRC信息；
第二媒体接入控制MAC控制单元CE；
第三数据包，该第三数据包的序列号或计数值与第四数据包的序列号或计数值相同或相邻，该第四数据包由该第一网络设备发送；
第二分组数据汇聚层协议PDCP控制协议数据单元PDU，该第二PDCP控制PDU包括第二编号，该第二编号用于指示该第二网络设备发送的第一个数据包。
具体而言，该第二RRC信息与该第二MAC CE都可以作为显性的信息，例如，第二RRC信息与该第二MAC CE可以作为显性的信息，例如，该第二RRC信息可以直接指示该终端设备停止与该网络设备#A的通信，释放该网络设备#A对应的协议栈及无线数据承载；该第二MAC CE可以通过报头的逻辑信道指示逻辑信道标识(Logical Channel Identify，LCID)域指示该终端设备停止与该网络设备#A的通信，或释放与该网络设备#A对应的协议栈及无线数据承载；该第二MAC CE、该第三数据包与该第二PDCP控制PDU可以作为隐性的信息来指示，该第二MAC CE可以通过报头中的LCID域指示该网络设备#A发送最后一个数据包，该终端设备可以根据该第三数据包或该第二PDCP控制PDU确定自己不再需要继续与该网络设备#A的通信，其中，该第二PDCP控制PDU的第二编号是与数据包相关的SN或COUNT值。
在步骤S330中，当该消息#1承载的是该第二RRC信息或该第二MAC CE时，该终端设备可以直接确定自已不再需要继续与该网络设备#A通信，从而，停止与该网络设备 #A的通信，或，释放对应于该网络设备#A的协议栈和数据无线承载。
在步骤S330中，当该消息#1承载的是该第二MAC CE时，该终端设备检测到该第二MAC CE后，表示该网络设备#A已经停止向自己发送数据包，则确定自己不再需要继续与该网络设备#A通信，从而停止与该网络设备#A的通信，或，释放对应与该网络设备#A的协议栈和数据无线承载。
在步骤S330中，当该消息#1承载的是该第三数据包时，该终端设备检测到该第三数据包的SN或COUNT值与从该网络设备#A接收到的最后一个数据包的SN或COUNT值相同或相邻，表示该网络设备#A已经将该网络设备#A缓存的数据包发送完毕，则确定自己不再需要继续与该网络设备#A通信，从而，停止与该网络设备#A的通信，或，释放对应于该网络设备#A的协议栈和数据无线承载。
在步骤S330中，当该消息#1承载的是该第二PDCP控制PDU，该终端设备根据该第二编号，将该第二编号所指示的数据包以及该第二编号所指示的数据包之前的所有数据包都接收后，停止与该网络设备#A的通信，或，释放对应于该网络设备#A的协议栈和数据无线承载。
当该网络设备#B基于上述不同内容确定该消息#1时，该消息#1所承载的内容可以相同，也可以不同。
例如，当该网络设备#B基于步骤S311所指示的测量报告#3A、步骤S312所指示的测量报告#3B、步骤S313所指示的该消息#3和步骤315所指示的无线链路失败消息#1发送该消息#1时，该消息#1承载的内容可以是该第二RRC信息和/或该第二MAC CE；
再例如，当该网络设备#B基于步骤S314所指示的该数据消息#2发送该消息#1时，该消息#1承载的内容可以是该第三数据包和/或该第二PDCP控制PDU，也可以是上述所有的该消息#1可以承载的内容。
应理解，该网络设备#B基于上述不同步骤所指示的内容确定该消息#1的内容仅为示意性说明，不应对本申请实施例构成限定。
可选地，该方法还包括：
该网络设备#B向该网络设备#A发送消息#4(即，该第四消息的一例)，该消息#4用于指示该网络设备#A停止该终端设备与该网络设备#A之间的通信，或，该消息#4用于指示该网络设备#A释放对应于该终端设备的协议栈和数据无线承载。
也就是说，该网络设备#B在确定该终端设备与该网络设备#A之间不再需要通信时，不仅向该终端设备发送该消息#1，使得该终端设备停止与网络设备#A的通信，或，释放对应于该网络设备#A的协议栈和数据无线承载，也向该网络设备#A发送该消息#4，
使得该网络设备#A停止与该终端设备的通信，或，释放对应于该终端设备的协议栈和数据无线承载。
因此，第二网络设备在该终端设备与第一网络设备可以不需要进行通信时，为了使得该第一网络设备知道该第一网络设备后续的行为(或者说，知道该终端设备与该第一网络设备之间的通信状态)，通过向该第一网络设备发送第四消息，可以使得该第一网络设备确定自己与该终端设备不需要进行通信，从而，停止与该终端设备的通信或者释放对应该终端设备的协议栈和数据无线承载，减少了该第一网络设备的功耗以及空口资源的浪费，有效地提高了通信过程中的灵活性。
同理，用于确定该网络设备#B发送该消息#4的条件可以是下述至少一个步骤所指示的内容：
可选地，在该网络设备#B向该第一网络设备发送第四消息之前，该方法还包括：
该网络设备#B接收该终端设备发送的测量报告#4A(即，该第四测量报告的一例)，该测量报告#4A用于指示该终端设备与该网络设备#A之间的信道质量小于或等于阈值；或，
该网络设备#B接收该网络设备#A发送的测量报告#4B(即，该第四测量报告的另一例)，该测量报告#4B用于指示该终端设备与该网络设备#A之间的信道质量小于或等于阈值；或，
该网络设备#B接收该终端设备发送的无线链路失败消息#2(即，第二无线链路失败消息的一例)，该无线链路失败消息#2用于指示该终端设备与该网络设备#A发生无线链路失败；或，
该网络设备#B接收该网络设备#A发送的数据消息#3(即，第三数据消息的一例)，该数据消息#3用于指示该网络设备#A停止向该终端设备发送数据包。
也就是说，该网络设备#B可以基于接收到的测量报告#4A、测量报告#4B、无线链路失败消息#2和数据消息#3中的至少一个消息发送该消息#4。
需要说明的是，在该网络设备#A发送该消息#1的情况下，该消息#4可以是该消息#2，用于该网络设备#A确定自己可以停止与该终端设备的通信，或，释放与该终端设备对应的协议栈和数据无线承载，从而，该网络设备#A基于该消息#2确定该消息#1，由该网络设备#A发送该消息1；在该网络设备#A未发送该消息#1的情况下，该消息#4可以是该网络设备#B直接基于接收到的各种消息确定是否发送该消息#4。
其中，该网络设备#B可以基于相同的消息作出决定，确定该终端设备和该网络设备#A之间是否该需要继续通信，在确定不再需要继续通信的情况下，向该终端设备发送该消息#1和向该网络设备#A发送该消息#4。
此种情况下，在该网络设备#A未发送该消息#1的情况下，该测量报告#3A可以是该测量报告#4A，该测量报告#3B可以是该测量报告#4B，该无线链路失败消息#2可以是该无线链路失败消息#1，该数据消息#3可以是该数据消息#2。
在本申请实施例中，该网络设备#B可以根据接收到的测量报告、该网络设备#A发送的数据消息、无线链路失败消息以及该消息#3等综合确定是否发送该消息#1和/或该消息#4。
注意，此处所描述的测量报告并不是该测量报告#3A、该测量报告#3B等所指示的信道质量小于或等于阈值，而是仅仅表示该终端设备与该网络设备#A之间的信道质量，可以是大于阈值，也可以是小于或等于阈值；同时，此处所描述的测量报告、数据消息以及无线链路失败消息等不代表任何情况下的消息(例如，上文所述的采用不同阿拉伯数字区分同一种功能的消息)，仅仅是想通过各种消息的作用说明本申请实施例中基于至少一种消息如何确定该消息#1和/或该消息#4。下面，为了简洁，仅以该网络设备#B发送该消息#1为例进行说明，该网络设备#B发送该消息#4的情况与发送该消息#1的情况类似。
例如，一种可选的实施例中，该网络设备#B基于测量报告和数据消息，确定是否发送该消息#1。
具体而言，该网络设备#B首先根据接收到的测量报告确定该终端设备与该网络设备#A之间的信道质量是否低于阈值：若该信道质量小于或等于该阈值，则发送该消息#1；若该信道质量大于该阈值，则暂时不发送该消息#1，接着，网络设备#B根据数据消息确定是否发送该消息#1：若该网络设备#B接收到数据消息，则发送该消息#1，若该网络设备#B未接收到数据消息，则不发送该消息#1，该网络设备#A和该终端设备继续维持双方的通信连接。
再例如，另一种可选的实施例中，该网络设备#B基于测量报告、数据消息、无线链路失败消息确定是否发送该消息#1。
具体而言，该网络设备#B首先根据是否接收到无线链路失败消息，若该网络设备#B接收到无线链路失败消息，则发送该消息#1；若该网络设备#B未接收到无线链路失败消息，则暂时不发送该消息#1；接着，该网络设备#B根据接收到的测量报告确定该终端设备与该网络设备#A之间的信道质量是否低于阈值：若该信道质量小于或等于该阈值，则发送该消息#1；若该信道质量大于该阈值，则暂时不发送该消息#1；最后，该网络设备#A根据数据消息确定是否发送该消息#1：若该网络设备#B接收到数据消息，则发送该消息#1，若该网络设备#B未接收到数据消息，则不发送该消息#1，该网络设备#A和该终端设备继续维持双方的通信连接。
应理解，上述举例仅为示意性说明，该网络设备#B可以根据上述任意至少两种消息确定是否发送该消息#1，具体根据哪些消息确定发送该消息#1和/或该消息#4，可以根据实际情况而定，本申请实施例不做任何限定。
以上，结合图2和图3，分别以该网络设备#A和该网络设备#B作为发送该消息#1的执行主体，对本申请实施例的无线通信道的方法进行了详细说明，下面，结合图4，以该终端设备作为发送用于指示该网络设备#A停止与该终端设备的通信连接或释放对应于该终端设备的协议栈和数据无线承载的消息的执行主体，对本申请实施例的无线通信道的方法进行详细说明。
图4所示为本申请再一实施例的无线通信的方法中的该终端设备、该网络设备#A和该网络设备#B的示意性交互图。
如图4所示，该方法包括：
步骤S410，该终端设备向网络设备发送的第五消息，该第五消息用于指示该网络设备#A停止该终端设备与该网络设备#A之间的通信，或，该第五消息用于指示该网络设备#A释放对应于该终端设备的协议栈和数据无线承载，该网络设备为该网络设备#A或该网络设备#B。
具体而言，该终端设备确定自己与该网络设备#A不再需要继续通信时，该终端设备向该网络设备#A或该网络设备#B发送消息，最终可以使得该网络设备#A基于收到的消息，也能够确定自己与该终端设备不再继续通信时，该网络设备#A也能够停止与该终端设备的通信，或，释放对应于该终端设备的协议栈和数据无线承载。
可选地，该终端设备可以根据以下至少一个条件发送该第五信息，该至少一个条件包括：
该终端设备与该第一网络设备的信道质量小于或等于阈值；
该终端设备与该第一网络设备发生无线链路失败；
该终端设备的定时器超时。
其中，该终端设备的定时器超时表示的是，系统为该终端设备配置一个定时器，当定时器的时长大于或等于预设时长时，该终端设备发送该第五消息。
因此，本申请提供的无线通信的方法，该终端设备在确定自己需要停止该终端设备与第一网络设备之间的通信或可以释放对应于该第一网络设备的协议栈和数据无线承载，导致自己与该第一网络设备无法通信，为了使得该第一网络设备也知道自己的行为(或者说，知道自己与该第一网络设备之间的通信状态)，通过向网络设备(第一网络设备或第二网络设备)发送第五消息，可以使得该第一网络设备确定自己与该终端设备不需要进行通信，从而，停止与该终端设备的通信或者释放对应该终端设备的协议栈和数据无线承载，可以减少该第一网络设备功耗以及空口资源的浪费等，有效地提高了通信过程中的灵活性。此外，该终端设备在发送第五消息后，也停止与该第一网络设备的通信或释放对应于该第一网络设备的协议栈和数据无线承载，也减少了该终端设备由于持续监听信道等造成的功耗以及空口资源的浪费，有效地提高了通信过程中的灵活性。
其中，为了使得该网络设备#A能够确定自己是否需要继续与该终端设备通信，该终端设备有两种方式发送该第五消息:
方式A
在步骤S411中，该终端设备向该网络设备#A发送消息#5A(即，第五消息的一例)。即，该终端设备直接将该消息#5A发送给该网络设备#A，该方式A适用于该终端设备与该网络设备#A能够正常通信的情况。
方式B
在步骤S412中，该终端设备向该网络设备#B发送消息#5B(即，第五消息的另一例)，对于该网络设备#B来说，该网络设备#B接收到该消息#5B后，该方法还包括：
该网络设备#B根据该消息#5B，向该网络设备#A发送消息#6(即，第六消息的一例)，该消息#6用于指示该网络设备#A停止该终端设备与该网络设备#A之间的通信，或，该消息#6用于指示该网络设备#A释放对应于该终端设备的协议栈和数据无线通信。
也就是说，从逻辑上来说，在方式B中，该网络设备#B将接收到的该消息#5B转发给该网络设备#A，从实现角度来说，通过消息#6的形式发送给该网络设备#A。
该方式B适用于该终端设备与该网络设备#A已经不能正常通信的情况。
因而，第二网络设备通过根据终端设备发送的第五消息生成第六消息，从而向第一网络设备发送该第六消息，或者说，该第二网络设备将接收到的第五消息通过第六消息的形式转发给该第一网络设备，在该终端设备与该第一网络设备无法正常通信的情况下，有效地避免了该第一网络设备无法知道是否需要停止与该终端设备的通信，或，是否需要释放对应于该终端设备的协议栈和数据无线承载的情况，进一步提高了通信过程中的灵活性。
应理解，上述步骤S411至S413并没有先后顺序，此处仅仅是为了说明该终端设备可能执行的步骤，实现中，可以根据实际情况执行相应的步骤。
对于该终端设备来说，在步骤S420中，该终端设备在发送该消息#5(即，消息#5A或消息#5B)后，停止与该网络设备#A之间的通信，或，释放对应于该网络设备#A的协议栈和数据无线承载。
对于该网络设备#A来说，在步骤S430中，该网络设备#A接收该终端设备发送的消 息#5A或该网络设备#B发送的消息#6后，停止该终端设备与该网络设备#A之间的通信，或，释放对应于该终端设备的协议栈和数据无线承载。
可选地，该第五消息承载以下至少一项：
第三无线资源控制RRC信息；
第五测量报告，该第五测量报告用于指示该终端设备与该第一网络设备之间的信道质量小于或等于阈值。
其中，测量报告#5(即，第五测量报告的一例)可以作为触发条件(或者说，该第五消息的隐性指示)，该网络设备#A接收到该测量报告#5时，就确定自己不再需要与该终端设备通信，即，停止与该终端设备的通信或释放对应于该终端设备的协议栈和数据无线承载。
