Description

转移业务的方法、装置、通信设备及存储介质 技术领域
本公开涉及无线通信技术领域但不限于无线通信技术领域，尤其涉及一种转移业务的方法、装置、通信设备及存储介质。
背景技术
为了支持终端与终端之间的直接通信，引入了直连链路(sidelink)通信方式。终端与终端之间的接口为PC-5。根据发送终端和接收终端之间的对应关系，直连链路(sidelink)支持三种传输方式，分别为单播、多播和广播。一个终端可以不直接与基站连接而通过另外一个终端的中继实现与基站的通信。其中，与基站没有连接的终端称为远端终端(remote UE)；提供中继功能的终端称为中继终端(relay UE)；远端终端与中继终端之间通过直连链路(sidelink)通信。
当终端离开网络覆盖范围时，为了保持同网络的连接，基站会将终端的业务转移到中继终端。基站会向终端发送无线资源控制(RRC，Radio Resource Control)消息，无线资源控制(RRC)消息用于指示终端将业务转移到目标中继终端。但是，终端与基站之间的信道质量是变化的，如此，在信道质量变化需要转移业务数据的传输时，如何尽快的进行业务数据的传输转移，一方面确保通信质量，另一方面减少延时，是相关技术需要进一步解决的问题。

请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统， 该无线通信系统可以包括：若干个用户设备110以及若干个基站120。
其中，用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，用户设备110可以是物联网用户设备，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网用户设备的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、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、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者，用户设备110也可以是无人飞行器的设备。或者，用户设备110也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线用户设备。或者，用户设备110也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站120可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。
其中，基站120可以是4G系统中采用的演进型基站(eNB)。或者，基站120也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协 议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站120的具体实现方式不加以限定。
基站120和用户设备110之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，用户设备110之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
这里，上述用户设备可认为是下面实施例的终端设备。
在一些实施例中，上述无线通信系统还可以包含网络管理设备130。
若干个基站120分别与网络管理设备130相连。其中，网络管理设备130可以是无线通信系统中的核心网设备，比如，该网络管理设备130可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备130的实现形态，本公开实施例不做限定。
为了方便对本公开任一实施例的理解，首先，通过一个实施例对一种 小区切换的场景和终端业务转移的场景进行说明。
为了提高小区切换的鲁棒性，第五代移动通信技术5G提出了基于条件的切换过程(CHO，Conditional Handover)。即网络可以提前为终端配置切换到的目标小区和小区切换的触发条件。当切换触发条件满足时，终端可以自行发起切换过程切换至目标小区，不需要网络再发送切换命令。网络可以为终端配置一个或多个条件切换目标小区的切换条件。切换条件包括A3和A5事件。其中，A3事件为：相邻小区的信道质量高于服务小区一定数值。A5事件为：相邻小区的信道质量高于一定门限且服务小区的信道质量低于一定门限。
这里，终端在进行小区选择时，会选择合适(suitable)的小区进行驻留。合适的小区为无线信号质量高于设置阈值且属于终端所选择的公共陆地移动网(PLMN，Public Land Mobile Network)的小区。
请参见图2，无线通信系统包括基站21、中继终端22、远端终端23。当远端终端位于服务小区边缘或者离开服务小区时，远端终端的业务数据会从在基站和远端终端之间传输转变为在中继终端与远端终端之间传输。
这里，一方面，在业务转移时，向中继终端转移业务，如果只考虑信号强度，在服务小区存在覆盖漏洞的区域中，可能会触发终端向中继终端进行业务转移。但是，这种情况下本不应该使用中继终端，而应该触发无线资源控制(RRC)连接建立，恢复与在此处有覆盖的网络的无线资源控制(RRC)连接。另一方面，当终端离开网络覆盖范围时，为了保持同网络的连接，基站会将终端的业务转移到中继终端。基站会向终端发送无线资源控制(RRC，Radio Resource Control)消息，无线资源控制(RRC)消息用于指示终端将业务转移到目标中继终端。但是，当终端与基站之间的信道质量快速下降时，终端可能无法正确接收到基站发送的无线资源控制(RRC)消息，这会导致无法将业务转移到中继终端。
如图3所示，本实施例中提供一种转移业务的方法，其中，应用于第一终端中，该方法包括：
步骤31，响应于确定满足业务转移条件，将第一终端与基站之间传输的业务数据，转移至在第一终端与第二终端之间传输，以将第二终端作为第一终端与基站进行通信的中继终端。
在一个实施例中，业务转移条件是由基站发送的；
或者，
业务转移条件是由通信协议规定的。
在一个实施例中，第一终端接收基站发送的业务转移条件。
在另一个实施例中，业务转移条件基于第一终端进行无线通信时的通信协议确定。
在一个实施例中，触发将第一终端与基站之间传输的业务数据，转移至在第一终端与第二终端之间传输，包括：
自行触发将第一终端与基站之间传输的业务数据，转移至在第一终端与第二终端之间传输。
在一个实施例中，终端可以是但不限于是手机、可穿戴设备、车载终端、路侧单元(RSU，Road Side Unit)、智能家居终端、工业用传感设备和/或医疗设备等。
在一个实施例中，基站为终端接入网络的接口设备。基站可以为各种类型的基站，例如，3G基站、4G基站、5G基站或其它演进型基站。
在一个实施例中，每个基站对应一个服务小区。基站可以给位于服务小区中的第一终端、第二终端提供无线接入服务。在一个实施例中，基站可以是第一终端的锚点基站。
在一个实施例中，第一终端和第二终端之间基于直连链路(sidelink)进行无线通信。
在一个实施例中，中继终端可以是具有中继功能的终端。
在一个实施例中，第一终端可以是中继终端。
在一个实施例中，第一终端能够获知服务小区中存在的第二终端。
在一个实施例中，基站可以预先将服务小区中的所有第二终端的标识信息或者部分第二终端的标识信息发送给第一终端。第一终端可以根据第二终端的标识选择第二终端，并与选择出的第二终端进行通信。在一个实施例中，第一终端基于与第二终端之间的无线信号强度选择第二终端。
在一个实施例中，在第一终端与基站之间的无线信号强度大于无线信号强度阈值时，第一终端与基站之间采用建立无线资源控制(RRC)连接的方式进行无线通信。
在一个实施例中，第二终端与基站之间基于无线网空口(例如，Uu口)的协议进行通信。第二终端与第一终端之间基于直连链路(sidelink)的协议进行通信。
在一个实施例中，业务转移可以是将第一终端与基站之间基于无线网空口(例如，Uu口)的协议进行传输的数据，转移至在第一终端与第二终端之间基于直连链路(sidelink)协议进行传输。
在一个实施例中，第二终端可以将从第一终端处接收到的业务数据通过无线网空口(例如，Uu口)协议发送至基站。第二终端也可以将从基站处接收到的业务数据通过直连链路(sidelink)协议发送至第一终端。
在一个实施例中，可以是接收基站通过无线资源控制(RRC)信令发送的业务转移条件。
在一个实施例中，响应于第一终端通过基站接入无线网络，接收基站发送的业务转移条件。
在一个实施例中，无线资源控制(RRC)信令可以是包括携带有业务转移条件的无线资源控制(RRC)连接重配置(RRCConnectionReconfiguration)信令。终端接收通过无线资源控制(RRC)连接重配置(RRCConnectionReconfiguration)信令发送的业务转移条件的 信息。这样，可以利用已有的无线资源控制(RRC)信令携带业务转移条件的信息，实现了无线资源控制(RRC)信令的复用，提升了信令的兼容性。
在一个实施例中，第一终端在确定出满足业务转移条件之前就可以接收基站发送的业务转移条件。
在一个实施例中，请再次参见图2，可以是在第一终端离开服务小区，当基站与第一终端之间的无线信号强度在预定时间段内始终小于时间阈值时，触发业务转移的流程。
在一个实施例中，可以是第一终端进入服务小区中的信号覆盖盲区，基站与第一终端之间的无线信号强度在预定时间段内始终小于时间阈值时，触发业务转移的流程。
在一个实施例中，当第一终端为对实时性均要求高的设备(如，手机)，可以配置预定时间段对应的时间长度小于第一时间阈值；当第一终端为对实时性均要求低的设备(如，定位设备)，可以配置预定时间段对应的时间长度小于第二时间阈值。这里，第一时间阈值小于第二时间阈值。这里，第一时间阈值越小，第一终端就能够更块地触发业务转移流程。本实施例中，可以满足不同设备对实时性的不同需求。
在一个实施例中，第一终端在需要将第一终端与基站之间传输的业务数据转移至在第一终端与第二终端之间传输时，可以测试第一终端与服务小区中存在的中继终端之间的信号强度，从多个中继终端中选择一个无线信号强度大于无线信号强度阈值的终端作为第二终端。这里，选择无线信号强度大于无线信号强度阈值的终端作为第二终端可以使得第一终端与第二终端间的无线通信质量更高。
在一个实施例中，业务转移条件可以是第一终端与第二终端之间进行通信的无线信号强度大于设置的信号强度阈值。
在一个实施例中，在第一终端离开服务小区，基站与第一终端之间的 无线信号强度在预定时间段内始终小于时间阈值时，触发业务转移的流程。业务转移的流程启动后，在满足第一终端与第二终端之间的信号强度大于设置的信号强度阈值时，将第一终端与基站之间传输的业务数据，转移至在第一终端与第二终端之间传输。
在本公开实施例中，第一终端在确定出满足业务转移条件之前就可以接收基站发送的业务转移条件。在确定出满足业务转移条件时，就可以直接触发将第一终端与基站之间传输的业务数据，转移至在第一终端与第二终端之间传输。相较于在需要转移业务时，第一终端才通过无线资源控制(RRC)消息从基站获取基站指示的第二终端，并将第一终端与基站之间传输的业务数据，转移至在第一终端与第二终端之间传输的方式。减少了因接收不到无线资源控制(RRC)消息而导致无法实现业务转移的情况，提升了业务转移的可靠性，提升了通信网络的稳定性。
如图4所示，本实施例中提供一种转移业务的方法，其中，该方法还包括：
步骤41，响应于确定第一终端与基站之间的无线信道质量小于第一设置阈值，且在确定出满足业务转移条件时，将第一终端与基站之间传输的业务数据，转移至在第一终端与第二终端之间传输。
在一个实施例中，确定第一终端与基站之间的无线信道质量小于第一设置阈值可以是确定第一终端与基站之间的无线信道质量在一个或多个预定时间段内小于第一设置阈值，也可以是确定第一终端与基站之间的无线信道质量在一个或多个预定时间点上小于第一设置阈值。
在一个实施例中，预定时间段或时间点由基站进行配置，基站将配置好的时间段或时间点的信息发送给第一终端。
在一个实施例中，当第一终端为对可靠性和实时性均要求高的设备(如，手机)，基站可以配置预定时间段对应的时间长度或预定时间段的数量小于第一阈值；当第一终端为对可靠性和实时性均要求低的设备(如， 定位设备)，基站可以配置预定时间段对应的时间长度或预定时间段的数量小于第二阈值。这里，第一阈值小于第二阈值。
在一个实施例中，第一设置阈值由基站进行配置，基站将配置好的第一设置阈值的信息发送给第一终端。
