Description

业务处理方法、装置、芯片及计算机程序 技术领域
本申请涉及无线网络技术,特别涉及业务处理方法、装置、芯片及计算机程序。
背景技术
时间敏感性网络(TSN,Time Sensitive Network)中,数据包会在特定的周期和时间点传输,而在从源端到目的端传输需要经过的多个节点称为TSN桥(bridge),它们会按照协商好的要求在特定的时间为特定的TSN数据预留好资源,保证其顺序的传输,从而保证源端到目的端的TSN数据传输时间是确定的。
为了支持TSN传输,5G系统整体作为一个TSN bridge,和5G系统对接的其它TSN bridge将5G系统视为一个普通的TSN bridge来进行TSN数据传输和信息交互。
目前的5G系统的跨基站切换主要包括基于N2接口切换以及基于Xn接口的切换。
对于TSN业务的支持,需要空口、核心网的支持,即需要保证固定的传输时延和专有功能的部署等,因此,需要限制终端设备切换或接入的区域,否则将无法保证TSN业务的顺利执行,另外,目前执行切换时,会将当前承载全部请求切换,这样会影响切换的速度和效率。

第一行为执行时间指示信息可包括:终端设备接收到第一基站发出的执行第一行为命令到发起执行第一行为的时间。
若根据第一指示信息确定出允许执行第一行为,那么当需要执行第一行为时,针对第一业务,第一基站可向终端设备发送执行第一行为命令,可选地,其中可携带有第一行为执行时间指示信息。
第一行为可包括切换,所述切换可包括5G系统内部切换、系统间切换或不同制式基站间的切换等。相应地,第一基站可向终端设备发送切换命令,在NR系统中可为同步重配置(Reconfiguration with sync),在长期演进(LTE,Long Term Evolution)系统中可为RRC连接重配置(RRC Connection Reconfiguration)包括移动控制信息(including the mobility Control Info)。终端设备执行第一行为可包括向第二基站小区发起随机接入、获得小区同步及发送切换完成消息等。
切换可包括准备阶段和执行阶段,如图9所示,图9为本申请实施例提供的包括准备阶段和执行阶段的切换过程示意图。
图9中所示的Step-1到step-5为准备阶段。其中:
Step 1-Step 2:源基站根据终端设备发送的测量报告决定触发切换。
Step 3:源基站向目标基站发送HO Request消息,其中包含RRC Container,RRC Container包含了目标基站为准备切换必需的信息,如至少包括目标小区ID,源基站给终端设备分配的小区无线网络临时标识(C-RNTI,CellRadio Network Temporary Identifier,无线资源管理(RRM,Radio Resource Management)配置信息包括终端设备的非活跃(Inactive)时间,接入层(AS,Access Stratum)基本配置(如天线信息、下行载波频率等),源基站上的QoS Flow与数据资源承载(DRB,Data Resource Bearer)的映射关系,源基站上的最小系统信息,不同RAT下终端设备能力信息,此外还可以包含终端设备上报的测量信息包括波束相关信息等。
Step 4:目标基站执行接入控制,包括对发来的QoS Flow和/或DRB建立是否接受。
Step 5:目标基站储备层1/层2的相关资源,发送切换请求确认(HO Request Ack)消息给源基站,该消息包含返回给源基站的透明容器(Transparent Container)。
图9中所示的Step 6到Step 8为执行阶段,其中:
Step 6:源基站向终端设备发送Uu Handover消息,此消息中包含需要接入的目标小区的消息(如可以包括目标小区的Cell Id,新的C-RNTI,目标基站的安全算法标识,专有随机接入信道(RACH,Random Access Channel)资源,RACH资源和同步信号块(SS Block,Synchronization Signal Block)的关联关系,RACH资源和终端设备特定的信道状态信息参考信号(CSI-RS,Channel State Information-Reference Signals)配置的关联关系,普通RAN资源,目标小区调度单元(SIB,Scheduling Unit)信息等)。
Step 7:源基站向目标基站发送SN状态转换(SN STATUS TRANSFER)消息,该消息中包含了源基站在执行切换前发送给终端设备的数据包的分组数据汇聚协议(PDCP,Packet Data Convergence Protocol)层的序列号(Sequence Number)信息。
Step 8:终端设备同步到目标小区,完成RRC切换过程。
图9中所示的Step 9到最后为切换完成阶段。该阶段的信令用于告诉核心网空口切换已完成,核心网将数据的发送路径由源基站改变到目标基站(Path Switch),源基站释放保存的终端设备恩上下文信息。
执行第一行为命令,即为step-6,发起执行第一行为即为Step-8–step-9,那么终端设备从收到Step 6到发起step8即为第一行为执行时间指示信息中指示的时间。
第一行为重新尝试时间可包括:向第二基站发起切换请求后获取到第二基站回复的失败指示时,再次发起切换请求的时间。
第一基站在向切换到的第二基站发送切换请求消息时,可仅携带部分数据流和/或会话信息,包括第一业务的数据流和/或会话信息。
第一行为还可包括无线资源控制(RRC,Radio Resource Control)重定向。相应地,第一基站可向终端设备发送RRC连接释放消息,终端设备执行的第一行为可包括向第二基站小区发起随机接入及完成RRC连接建立请求等。
另外,第一基站可向第二基站触发切换请求,如第一基站可向第二基站发送切换请求消息,第一基站可获取来自第二基站的第二指示信息,第二指示信息可至少包括以下之一:第一数据流和/或会话不能建立;第一数据流和/或会话的QoS参数不能保障;切换请求失败。
第一基站获取到第二指示信息后,可取消切换流程或继续执行切换流程。
可选地,第一基站可从网络侧获取第三指示信息,根据第三指示信息确定取消切换流程或继续执行切换流程。如网络侧可利用第三指示信息直接指示取消切换流程还是继续执行切换流程。
若确定取消切换流程,第一基站可在第一时间内不再向第二基站触发切换流程或发送切换请求。其中,第一时间可获取自第二基站和/或网络侧和/或静态配置,具体取值不作限制。
若确定取消切换流程,第一基站还可向终端设备和/或网络侧发送第四指示信息,第四指示信息用于指示终端设备停留在第一基站的覆盖范围内或显示终端设备离开当前基站覆盖范围后不能保障第一业务(第一数据流和/或会话对应的业务)的QoS。
通过第四指示信息,可以使终端设备知道若离开第一基站的覆盖范围,那么第一业务将会无法保障,如可在终端设备的屏幕上显示离开当前基站覆盖范围后将不能保障第一业务的QoS等,从而使得终端设备尽量停留在第一基站的覆盖范围内。在第一基站的覆盖范围内,可以通过终端设备与第一基站建立的连接传送第一业务的数据包。
第四指示信息的内容可与第二指示信息相同或不同,若不同,第四指示信息可至少包括以下之一:第一数据流和/或会话对应的第一业务不能执行切换;第一业务不能在第二基站执行;第一业务只能在第一基站执行等等。
上述第一业务可为TSN业务,但并不局限于TSN业务,对于其它业务同样适用,如超可靠低时延通信(URLLC,Ultra Reliability and Low Latency Communication)业务等。

终端设备可获取来自第一基站针对第一业务的执行第一行为命令,执行第一行为命令中还可携带有第一行为执行时间指示信息和/或目标信息信息(执行第一行为后连接到的基站)等。
终端设备可根据第一指示信息确定是否拒绝执行第一行为。比如,终端设备确定自身不支持第一行为,那么则可拒绝执行第一行为,或者,终端设备确定第二基站位于第一业务支持区域之外,那么可也拒绝第一行为等。
若终端设备确定执行第一行为,那么可按照第一行为执行时间指示信息的指示触发第一行为,即终端设备接收到第一基站发出的执行第一行为命令后,等待第一行为执行时间指示信息中指示的时长后,发送执行第一行为的第一条消息。
第一行为可包括切换,所述切换可包括5G系统内部切换、系统间切换或不同制式基站间的切换等。相应地,执行第一行为命令可包括切换命令,执行第一行为可包括终端设备向第二基站小区发起随机接入、获得小区同步及发送切换完成消息等。
第一行为重新尝试时间可包括:向第二基站发起切换请求后获取到所述第二基站回复的失败指示时,再次发起切换请求的时间。
第一行为还可包括RRC重定向。相应地,执行第一行为命令可包括RRC连接释放消息,执行第一行为可包括终端设备向第二基站小区发起随机接入及完成RRC连接建立请求等。
由于第一业务如TSN可能只在局部支持,因此当终端设备移出第一业务支持区域时,终端设备和/或网络侧可发起针对第一业务对应的会话和/或数据流等的释放、修改、挂起等,当终端设备移入第一业务支持区域时,终端设备和/或网络侧可发起针对第一业务对应的会话和/或数据流等的建立、修改、恢复等,所述会话可为PDU会话。
对于终端设备来说,当终端设备移出有效区域时,针对第一业务,可向网络侧发送第一请求消息,触发网络侧执行第一操作,当终端设备移入有效区域时,针对第一业务,可向网络侧发送第二请求消息,触发网络侧执行第二操作。
其中,第一请求消息中可携带有对象信息以及第一操作信息。对象信息可至少包括以下之一:业务标识、数据流信息、会话标识、空口承载信息等。第一操作可至少包括以下之一:释放对象信息对应的上下文;修改对象信息对应的上下文;挂起或保留对象信息对应的上下文等。

可选地,上述业务标识可为用来指示特定业务的标识,数据流信息可为QFI信息,空口承载信息可为无线承载标识(Radio Bearer Id)等。
以对象信息为业务标识,第一操作为释放对象信息对应的上下文,第二操作为建立对象信息对应的上下文为例,当终端设备移出有效区域时,终端设备可向网络侧发送第一请求消息,其中可携带有业务标识以及释放业务标识对应的上下文信息,相应地,网络侧可释放业务标识对应的业务的上下文,当终端设备移入有效区域时,终端设备可向网络侧发送第二请求消息,其中可携带有业务标识以及建立业务标识对应的上下文信息,相应地,网络侧可建立业务标识对应的业务的上下文。
另外,终端设备还可获取来自第一基站的第四指示信息,第四指示信息用于指示终端设备停留在第一基站的覆盖范围内或显示终端设备离开当前基站覆盖范围后不能保障第一业务的QoS,从而避免终端设备移出第一基站的覆盖范围。也就是说,通过第四指示信息,可以使终端设备知道若离开第一基站的覆盖范围,那么第一业务将会无法保障,从而使得终端设备尽量停留在第一基站的覆盖范围内。
第四指示信息可至少包括以下之一:第一数据流和/或会话不能建立;所述第一数据流和/或会话的QoS参数不能保障;切换请求失败;第一数据流和/或会话对应的第一业务不能执行切换;第一业务不能在第二基站执行;第一业务只能在第一基站执行。
上述第一业务可为TSN业务,但并不局限于TSN业务,对于其它业务同样适用,如URLLC业务等。

另外,对于网络侧来说,若终端设备移出有效区域,针对第一业务,网络侧可根据终端设备发送的第一请求消息触发或主动触发执行第一操作,若终端设备移入有效区域,针对第一业务,网络侧可根据终端设备发送的第二请求消息触发或主动触发执行第二操作。
其中,第一请求消息中可携带有对象信息以及第一操作信息。对象信息可至少包括以下之一:业务标识、数据流信息、会话标识、空口承载信息等。第一操作可至少包括以下之一:释放对象信息对应的上下文;修改对象信息对应的上下文;挂起或保留对象信息对应的上下文等。
第二请求消息中可携带有对象信息以及第二操作信息。对象信息可至少包括以下之一:业务标识、数据流信息、会话标识、空口承载信息等。第二操作可至少包括以下之一:建立对象信息对应的上下文;修改对象信息对应的上下文;恢复对象信息对应的上下文等。

另外,在上述实施例中,对于不同实体侧(如第一基站侧、终端设备侧、网络侧)的描述都各有侧重,某一实体侧中没有详述的部分,可以参见其它实体侧中的相关描述。
总之,采用本申请所述方案,第一基站可获取来自网络侧的第一指示信息,其中可包括业务支持指示信息和/或有效区域指示信息和/或第一行为指示信息和/或终端设备状态指示信息和/或第一行为执行时间指示信息等各种指示信息,从而有效规定了业务的有效区域等,对于业务的合理部署和切换控制等提供了很大帮助,而且,第一基站在向第二基站和/或核心网发送切换请求消息时,可仅携带部分数据流和/或会话信息,无需将当前承载全部请求切换,从而可提升切换速度和效率等。
