数据传输方法、装置及网络侧设备
交叉引用

技术领域
本申请属于无线通信技术领域,具体涉及一种数据传输方法、装置及网络侧设备。
背景技术
在无线通信系统中,当用户终端(User Equipment,UE)移动并驻留到一个不提供某个业务(如多播/广播业务(Multicast/Broadcast Service,MBS)等)的小区时,可能出现业务连续性差的问题。
例如,在新空口(New Radio,NR)MBS中,对于高服务质量(Quality of Service,QoS)的MBS业务,UE必须在连接态接收该MBS业务,当该MBS业务的数据暂时没有提供时,其相应的N3和无线接入网络(Radio Access Network,RAN)的资源可以被挂起且UE可以被释放到非RRC连接态(non-RRCConnected)。考虑到一旦终端处于非RRC连接态时,可能发生小区重选,并移动到一个传统基站(即非增强的基站,没有多播控制信道(Multicast Control Channel,MCCH)的通知机制),那么,当该MBS的数据再次到达并恢复时,由于UE并不知道该MBS业务已经恢复,也就不能发起无线资源控制(Radio Resource Control,RRC)连接进入RRC连接态去接收数据。

如图2所示,为本申请一示例性实施例提供的数据传输方法200的流程示意图,该方法200可由第一网络节点执行,例如,可由安装于所述第一网络节点中的软件和/或硬件执行,所述方法200至少包括如下步骤。
S210,向第二网络节点发送第一数据。
其中,所述第一网络节点向所述第二网络节点发送的所述第一数据,可以为以下(1)-(3)中的至少一项。
(1)第一寻呼指示,用于指示所述第二网络节点发送第二寻呼指示给终端。本实施例中,所述第一寻呼指示可以是RAN寻呼消息(paging message),如XN口的RAN pagingmessage,或NG口的CNpaging message等。
(2)广播指示,指示用于通知所述第二网络节点发送广播消息给所述终端。本实施例中,所述广播消息可以为MBS业务相关的系统消息,和/或MBS业务相关的控制信道(如MCCH)发送的信令消息等。
(3)组寻呼指示,本实施例中,以NR MBS为例,该组寻呼指示可以用于指示MBS业务标识,比如临时移动组标识(Temporary Mobile Group Identity,TMGI),但不是用于指示终端标识。
本实施例中,所述第一网络节点通过发送所述第一数据给所述第二网络节点,能够使得所述第二网络节点发送第二数据给所述终端,以通知所述终端发起RRC连接进入RRC连接态去接收数据或者在非RRC连接态继续接收数据,由此确保数据业务的连续性。
其中,在所述第一数据为第一寻呼指示和所述广播指示的情况下,所述第一数据的发送过程可以如下。
一种实现方式中,所述第一网络节点可以通过两条消息分开发送所述第一寻呼指示和所述广播指示。例如,所述第一网络节点先发送所述第一寻呼指示对应的消息,再发送所述广播指示对应的消息;又例如,所述第一网络节点也可以先发送所述广播指示对应的消息,再发送所述第一寻呼指示对应的消息。
另一种实现方式中,所述第一网络节点可以通过一条消息同时发送所述寻呼指示和所述广播指示。例如,所述第一网络节点可以将所述广播指示加入所述第一寻呼指示,以在增强所述第一寻呼指示后,发送所述第一寻呼指示;也可以是,重新定义一条新的消息,再将所述第一寻呼指示和所述广播指示加入所述消息后,发送所述消息。
相应的,根据所述第一网络节点发送所述第一数据的不同,所述第二网络节点可以通过两条消息分开接收所述第一寻呼和所述广播指示,或也可以通过一条消息同时接收所述寻呼指示和所述广播指示。
需要理解的是,在所述第一数据为第一寻呼指示和组广播指示,或者、所述第一数据为广播指示、第一寻呼指示和组广播指示,或者,所述第一数据为组广播指示时,所述第一网络节点发送第一数据的发送方式可以参照前述描述,如可以通过多条消息分开发送,也可以通过一条消息发送,在此不做限制。
在本申请实施例中,所述第一网络节点通过向第二网络节点发送第一数据,所述第一数据为第一寻呼指示、广播指示、组广播指示中的至少一种,由此,能够解决终端驻留到一个不提供某个业务的小区时,可能出现的业务 连续性差的问题。
如图3所示,为本申请一示例性实施例提供的数据传输方法300的流程示意图,该方法300可由第一网络节点执行,例如,可由安装于所述第一网络节点中的软件和/或硬件执行,所述方法300至少包括如下步骤。
S310,向第二网络节点发送第一数据。
其中,S310的实现过程除了可参照方法200中的相关描述之外,作为一种可能的实现方式中,所述第一网络节点可以包括第一基站和/或核心网功能。所述核心网功能可以包括但不限于接入和移动管理功能(Access and Mobility Management Function,AMF)、会话管理功能(Session Management Function,SMF)、MB-SMF、用户面管理功能(User Plane Function,UPF)、MB-UPF等中的至少一个等。
所述第二网络节点为以下(1)-(11)至少一项。
(1)位于RNA内的第二基站。其中,所述RNA内,可以理解为基于RAN通知的区域(RAN-based Notification Area)。本实施例中,所述RNA可以但不限于基于终端标识确定,比如以所述第一数据为组寻呼指示为例,所述第一网络节点获得终端的终端标识,并通过该终端标识确定在终端的RNA中发送组寻呼指示。
(2)位于注册区域(Registration Area,RA)内的第二基站。本实施例中,所述注册区域可以但不限于基于终端标识确定。比如以所述第一数据为组寻呼指示为例,第一网络节点获得终端的终端标识,通过该终端标识确定在终端的RA中发送组寻呼指示。
(3)位于业务区域内的第二基站。其中,所述业务区域可以是MBS业务的业务区域等,本实施例对此不做限制。
(4)基于终端标识确定的跟踪区域(Tracking Area)中的基站;比如所述第一网络节点获得终端标识,通过该终端标识确定在终端的跟踪区域中发送组寻呼指示。
(5)基于终端标识确定的上一个服务小区所属的基站;比如以所述第一 数据为组寻呼指示为例,所述第一网络节点获得UE的标识,通过该终端标识确定发送组寻呼指示给终端的上一个服务小区所属的基站。可以理解,所述上一个服务小区可以是指:在终端上下行释放时,为该终端提供服务的NG-RAN节点。
(6)基于终端标识确定的上一个服务小区的邻小区所属的基站;比如以所述第一数据为组寻呼指示为例,所述第一网络节点获得终端标识,通过该终端标识确定发送组寻呼指示给终端的上一个服务小区的邻小区所属的基站。
(7)基于终端标识确定的上一个服务小区所属的基站的邻基站;比如以所述第一数据为组寻呼指示为例,所述第一网络节点获得终端标识,通过该终端标识确定发送组寻呼指示给终端的上一个服务小区所属基站的邻基站。
(8)基于终端标识确定的推荐小区所属的基站;比如以所述第一数据为组寻呼指示为例,在终端上下行释放时,NG-RAN节点可能会给AMF提供一个推荐小区和NG-RAN节点的列表(a list of recommended cells and NG-RAN nodes)作为后续paging message的辅助信息。
(9)基于终端标识确定的基站;比如在UE上下行释放时,NG-RAN节点可能会给AMF提供a list of recommended cells and NG-RAN nodes作为后续pagingmessage的辅助信息,即基于UE标识确定的基站为括号里的NG-RAN nodes。
(10)基于终端标识确定的无线接入网寻呼区域信息中的小区所属的基站;比如以所述第一数据为组寻呼指示为例,所述第一网络节点获得终端标识,并通过该终端标识确定发送组寻呼指示给终端的无线接入网寻呼区域(RAN Paging Area)中RAN区域标识(ID)中的Cells所属的基站。
(11)为基于终端标识确定的RAN Paging Area中RAN Area标识对应的基站。比如以所述第一数据为组寻呼指示为例,所述第一网络节点获得终端标识,通过该终端确定发送组寻呼指示给终端的RAN Paging Area中的RAN Area ID中的基站。
进一步,请再次参阅图3,S310的实现过程可以如下S311中所示。
S311,根据所述第二网络节点是否具备第一能力,向所述第二网络节点发送第一数据。
其中,所述第一能力可以理解为所述第二网络节点是否为增强型基站或者是否具备MBMS(或者MBS)能力或者是否可以通过核心网部分的共享传递(shared delivery)方式发送MBMS(或者MBS)的数据中的至少一项。在此基础上,前述的S311中所述的根据所述第二网络节点是否具备第一能力,向所述第二网络节点发送所述第一数据可以包括(1)或(2)以下任一项。
(1)在所述第二网络节点具备第一能力的情况下,向所述第二网络节点发送广播指示,所述广播指示用于通知所述第二网络节点发送广播消息。
例如,所述第二网络节点具备第一能力,可以认为所述第二网络节点为增强型基站或者具备MBMS(或者MBS)能力或者可以通过核心网部分的共享传递方式发送MBMS(或者MBS)的数据中的至少一项,在此情况下,所述第一网络节点向所述第二网络节点发送广播指示,以通知所述第二网络节点发送广播消息给终端,进而使得终端发起RRC连接进入RRC连接态去接收数据或者在非RRC连接态继续接收数据,由此确保数据业务的连续性。
(2)在所述第二网络节点不具备第一能力的情况下,向所述第二网络节点发送第一寻呼指示。
例如,所述第二网络节点不具备第一能力,可以认为所述第二网络节点为传统基站,或者不可以通过核心网部分的共享传递方式发送MBMS(或者MBS)的数据,但可以通过协议数据单元会话(Protocol Data Unit session,PDU session)或者核心网部分为单独传递(individual delivery)的方式发送MBMS或者MBS数据。在此情况下,所述第一网络节点向所述第二网络节点发送第一寻呼指示,以指示所述第二网络节点发送第二寻呼指示给终端,使得所述终端发起RRC连接进入RRC连接态去接收数据或者在非RRC连接态继续接收数据,由此确保数据业务的连续性。
需要注意的是,在前述给出的各实现方式中,所述第一数据可以包括以下至少一项。
(1)终端标识,其中,所述终端标识可以是需要接收所述第一数据的终端的标识等。
(2)业务标识,所述业务标识可以为MBS业务的标识,如TMGI,也可以是MBMS业务的标识等。
(3)会话标识(session identifier),其中,所述会话标识可以为MBS session的标识等。
进一步,本实施例中,所述第二网络节点在接收到第一网络节点发送的所述第一数据后,可以根据自身是否具备第一能力和/或所述第一数据,确定发送或不发送第二数据给所终端,下面结合不同的示例对其实现过程进行说明。
示例1
如果所述第二网络节点根据自身的第一能力,发送或者不发送第二数据给所述终端,那么,其实现过程可以包括如下(1)-(4)至少之一。
(1)在所述第二网络节点不具备第一能力、且所述第一数据为广播指示的情况下,所述第二网络节点可以不发送第二数据给终端。
(2)在所述第二网络节点不具备第一能力、且所述第一数据为第一寻呼指示的情况下,所述第二网络节点发送第二数据给终端。
(3)在所述第二网络节点具备第一能力、且所述第一数据为广播指示的情况下,所述第二网络节点发送第二数据给终端。
(4)在所述第二网络节点具备第一能力、且所述第一数据为第一寻呼指示的情况下,所述第二网络节点发送第二数据给终端。
示例2
如果所述第二网络节点根据接收到的第一数据,发送第二数据给终端,那么,其实现过程可以包括如下(1)-(3)中至少之一。
(1)基于第一数据中的所述第一寻呼指示,发送第二数据给终端。
(2)基于第一数据中的所述广播指示,发送第二数据给终端。
(3)基于首次接收到的第一数据,发送第二数据给终端。例如,如果所 述第二网络节点多次接收到第一网络节点发送的第一数据,所述第二网络节点仅根据首次或第一次接收到的第一数据发送第二数据给所述终端。
前述示例1和示例2中,所述第二数据可以是所述第二网络节点对接收到的至少一个第一数据中包括的第一寻呼指示和/或广播指示进行筛选、合并等处理后得到,也可以是基于接收到的至少一个第一数据中包括的第一寻呼指示、广播指示、组广播指示中的至少一种,生成所述第二数据后发送给所述终端,在此不做限制。
在此情况下,所述第二数据可以包括第二寻呼指示和/或广播消息,其中,所述第二寻呼指示和所述广播消息用于通知终端,发起RRC连接进入RRC连接态去接收数据或在非RRC连接态继续接收数据,由此确保数据业务的连续性。
例如,在所述第二网络节点为非增强基站(如传统基站)时,发送第二寻呼指示,以通知所述终端;又例如,在所述第二网络节点为增强基站时,发送广播消息来通知所述终端。
一种实现方式中,所述广播消息至少可以包括如下(1)-(3)中至少之一。
(1)调度信息,如MBS数据的调度信息等。
(2)业务信息,如MBS业务信息、MBMS业务信息等。
(3)状态信息,如MBS业务的会话开始(start)、恢复、激活(active)、挂起(suspend)、去激活(deactive)、停止(stop)、删除(delete)通知等状态的状态信息。
