Description

数据无线承载的恢复方法及装置、存储介质、电子装置
本申请要求在2018年08月09日提交中国专利局、申请号为201810904576.9的中国专利申请的优先权,该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域,具体而言,涉及一种数据无线承载的恢复方法及装置、存储介质、电子装置。
背景技术
在第三代合作伙伴计划(3GPP,3rd Generation Partnership Project)系统中,引入了一种新的无线资源控制(RRC,Radio Resource Control)状态,即为RRC非活动状态(RRC_INACTIVE)。用户设备(User Equipment,UE)从RRC非活动状态可通过RRC连接恢复过程(RRC connection resume)恢复(resume)RRC连接回到RRC连接态。相关技术中约定了非活动状态的UE在RRC连接恢复过程中,在接收到消息MSG4之后,恢复UE配置的所有数据无线承载。
同时,在3GPP接入网技术中,还存在一种双连接(DC,dual connection)的连接模式。在DC模式下,UE同时和两个不同网络侧网元间建立数据无线承载,其中,一个网络网元称为该UE的主节点(Master Node,MN),另一个网络侧网元称为辅节点(Secondary Node,SN)。
相关技术中UE在RRC连接恢复过程中所采用的数据无线承载的恢复方法并没有考虑对配置了双连接的UE,在RRC恢复过程中如何恢复对应连接配置的数据无线承载的问题,同时,相关技术中UE在RRC连接恢复过程中由于采用的是恢复UE配置的所有数据无线承载,故在新的无线接入网结构中未能实现对RRC连接恢复过程进行优化。
相关技术中,针对上述在恢复数据无线承载的过程中如何选择恢复部分所需的数据无线承载的问题,相关技术中尚未提出解决方案。
发明内容

根据本申请的另一个实施例,提供了一种数据无线承载的恢复方法,包括:
接收用户设备发送的指示信息,其中,所述指示信息用于指示用户设备所保持的数据无线承载中的第一数据无线承载,所述第一数据无线承载为需要发送上行数据的数据无线承载;根据所述指示信息返回配置信息至所述用户设备,其中,所述配置信息用于指示所述用户设备根据所述配置信息恢复所述第一数据无线承载。
根据本申请的另一个实施例,提供了一种数据无线承载的恢复装置,包括:
指示模块,用于向网络侧网元发送指示信息,其中,所述指示信息用于指示用户设备所保持的数据无线承载中的第一数据无线承载,所述第一数据无线承载为需要发送上行数据的数据无线承载;
接收模块,用于接收所述网络侧网元根据所述指示信息返回的配置信息;
恢复模块,用于根据所述配置信息恢复所述第一数据无线承载。
根据本申请的另一个实施例,提供了一种数据无线承载的恢复装置,包括:
获取模块,用于接收用户设备发送的指示信息,其中,所述指示信息用于指示用户设备所保持的数据无线承载中的第一数据无线承载,所述第一数据无线承载为需要发送上行数据的数据无线承载;
配置模块,用于根据所述指示信息返回配置信息至所述用户设备,其中,所述配置信息用于指示所述用户设备根据所述配置信息恢复所述第一数据无线承载。
根据本申请的又一个实施例,还提供了一种存储介质,所述存储介质中存储有计算机程序,其中,所述计算机程序被设置为运行时执行上述任一项方法实施例中的步骤。
根据本申请的又一个实施例,还提供了一种电子装置,包括存储器和处理器,所述存储器中存储有计算机程序,所述处理器被设置为运行所述计算机程序以执行上述任一项方法实施例中的步骤。
通过本申请,由于网络侧网元可根据用户设备发送的指示信息,以在数据无线承载中根据指示信息对于需要发送上行数据的第一数据无线承载将配置信息返回至用户设备中,以使得用户设备根据配置信息恢复第一数据无线承载, 因此,可以解决相关技术中在恢复数据无线承载的过程中如何选择恢复部分所需的数据无线承载的问题,达到仅根据需求恢复部分数据无线承载的效果。

具体实施方式
下文中将参考附图并结合实施例来详细说明本申请。需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是,本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。
为进一步说明本实施例中的技术方案,以下对于本实施例涉及的部分技术名词进行补充说明:
对于RRC非活动状态下的UE,在网络侧网元和UE均保持有该UE的接入层(Access Stratum,AS)的上下文信息,AS上下文信息包括该UE的安全上下文(security context),信令无线承载(Signaling Radio Bearer,SRB)和数据无线承载(Data Radio Bearer,DRB)的配置信息,以及数据无线承载对应的(Protocol Data Unit session,PDU session)和(Quality of Service Flow,QoS flow)的信息、分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)、无线链路层控制协议(Radio Link Control,RLC)的配置信息和可能存在的状态信息。
非活动状态UE的行为类似于RRC空闲态(RRC_IDLE)的UE,即没有专用的无线资源(dedicated radio resources);网络侧网元为非活动状态UE维护核心网(core network,CN)到接入网网元的控制面和用户面连接。维护该UE 的AS上下文的接入网网元被称为该UE的锚点网元(Anchor Node)。处于RRC非活动态的UE的DRB处于挂起的状态(suspended)。
UE从RRC非活动状态通过RRC连接恢复过程恢复RRC连接回到RRC连接态。具体的,UE在随机接入过程(RACH procedure)中,通过MSG3发送RRC连接恢复请求消息,携带该UE的标识、连接恢复的原因,以及安全验证信息等。在接收到网络侧网元发送的MSG4消息后,UE根据本地保存的AS层上下文中的配置以及MSG4中携带的配置信息,恢复UE处于挂起状态的DRB。
对于采用DC的连接模式的UE,在DC模式下,UE同时和两个不同网络侧网元间建立数据无线承载,其中,一个网络网元称为该UE的MN,另一个网络侧网元称为SN,UE与MN间建立有信令无线承载SRB0,SRB1以及可选的SRB2。网络为UE在MN网元下配置的一组小区主小区组(Mater Cell group,MCG)的无线资源称为MCG配置(Master Cell Group configuration,MCG configuration),在SN网元下配置的一组小区辅小区组(Secondary Cell group,SCG)配置的无线资源称为SCG配置(Secondary Cell Group configuration,SCG configuration)。
根据数据无线承载的协议层实体在两个网元间分布的不同,所述的数据无线承载类型包括:主节点终结的主小区组承载(MN terminated MCG bearer),主节点终结的辅小区组承载(MN terminated SCG bearer),主节点终结的分离承载(MN terminated splite bearer),SN terminated MCG bearer,辅节点终结的辅小区组承载(SN terminated SCG bearer)以及辅节点终结的分离承载(SN terminated split bearer)。图1为SN terminated MCG bearer的协议实体分布示意图,如图1所示,SN terminated MCG bearer是指该数据无线承载的PDCP实体建立在SN网元,RLC协议实体和媒体接入控制(Medium Access Control,MAC)协议实体建立在MN网元的一种无线承载形式,SN terminated split bearer是指该数据无线承载的PDCP实体建立在SN网元,在MN和SN两个网元中分别建立有指该数据无线承载RLC协议实体和MAC协议实体的一种无线承载形式。
在3GPP讨论结论中,在RRC连接态配置有双连接的UE在被转换到RRC非活动态时,UE将在本地保存建立在MN和SN的资源块(Resource Blocks,RB)的配置信息(RB配置信息包括:数据无线承载、PDU session、QoS flow、与核心网的用户面连接等配置信息),也将保存有MCG和SCG配置信息,MCG和SCG配置信息(MCG configuration,SCG configuration)包括分别建立在MN和SN下小区的RLC承载(RLC bearer)的配置信息。
实施例1
在本实施例中提供了一种数据无线承载的恢复方法,图2是根据本发明实 施例的数据无线承载的恢复方法的流程图(一),如图2所示,该流程包括如下步骤:
步骤S102,向网络侧网元发送指示信息,其中,指示信息用于指示用户设备所保持的数据无线承载中的第一数据无线承载,第一数据无线承载为需要发送上行数据的数据无线承载。
步骤S104,接收网络侧网元根据指示信息返回的配置信息。
步骤S106,根据配置信息恢复第一数据无线承载。
通过上述步骤,由于网络侧网元可根据用户设备发送的指示信息,以在数据无线承载中根据指示信息对于需要发送上行数据的第一数据无线承载将配置信息返回至用户设备中,以使得用户设备根据配置信息恢复第一数据无线承载,因此,可以解决相关技术中在恢复数据无线承载的过程中如何选择恢复部分所需的数据无线承载的问题,达到仅根据需求恢复部分数据无线承载的效果。
具体而言,上述步骤通过恢复部分数据无线承载,以对于配置了双连接的UE,可具体选择双连接中需要进行上行数据发送的一侧进行数据无线承载的恢复,进而使得双连接配置下的UE可实现对应的数据无线承载的恢复;而对于其它配置下的UE,由于在RRC的恢复过程中无需再统一恢复所有的数据无线承载,故使得UE的RRC的恢复过程得到优化,以达到节省网络和UE的信令开销、电池消耗和处理延时的目的。
此外,上述步骤的执行主体为用户设备或终端。
具体而言,如图3是根据本发明实施例的数据无线承载的恢复方法的交互示意图,用户设备与网络侧网元之间的交互还可以采用如下的实现方式:
