Abstract

本发明公开了一种会话停止的指示、处理方法及装置、存储介质。其中,该方法包括:接入网网元确定MBMS会话已经结束;接入网网元向UE发送第一指示信息,其中,第一指示信息用于指示MBMS会话已经结束。本发明解决了相关技术中所提供的会话停止方案无法适用于NB-IoT和eMTC的技术问题。

Description

会话停止的指示、处理方法及装置、存储介质 技术领域
本发明涉及窄带物联网领域,具体而言,涉及一种会话停止的指示、处理方法及装置、存储介质。
背景技术
在第三代合作伙伴计划(3rd Generation Partnership Project,简称3GPP)长期演进(LTE)中,引入了单小区点到多点传输(Signal cell Point To Multipoint,简称为SC-PTM),SC-PTM技术用于实现在单小区(a single cell)中传输点到多点的下行多媒体广播多播(多媒体广播多播业务(Multimedia Broadcast and Multicast Service,简称为MBMS)业务。SC-PTM引入了两种逻辑信道,即单小区多播控制信道(Signal cell Multimedia Control Channel,简称为SC-MCCH)和单小区多播传输信道(Signal cell Multimedia Transmission Channel,简称为SC-MTCH)。在LTE中,SC-MCCH与SC-MTCH均通过物理下行共享信道(High Speed Physical Downlink Shared Channel,简称为PDSCH)进行承载。
SC-MCCH信道承载传输MBMS业务相关的控制信息,其包括但不限于:业务的标识、调度信息。在LTE中,承载SC-MCCH的PDSCH为动态调度。具体地,在系统消息块20(SIB20)中指示SC-MCCH信道的调度信息,其可以包括但不限于:修改周期、重复周期、偏移(offset)、第一个子帧(first subframe)以及可能被调度的区间长度(duration)。这些参数限定了SC-MCCH可能被调度的duration的区间,即演进基站(eNB)在SC-MCCH可能被调度的duration区间中的特定子帧中调度SC-MCCH。
图1是根据相关技术的LTE中SC-MCCH信道的调度方式示意图。如图1所示,SC-MCCH的修改周期用来指示SC-MCCH消息可能被修改的边界,SC-MCCH重复周期为调度发送SC-MCCH消息的周期,offset是指duration起始无线帧相对SC-MCCH重复周期起始无线帧的偏移无线帧个数,first subframe为duration从其起始无线帧中第几个无线子帧开始。Duration的长度为duration持续的无线子帧的数量。eNB使用单小区无线网络临时标识(Signal cell Temporary Cell Radio Network Temporary Identifier,简称为SC-RNTI)对物理下行控制信道(Physical Downlink Control CHannel,简称为PDCCH)中的下行控制信息(Downlink Control Information,简称 为DCI)进行加扰。
一个SC-MTCH承载一个MBMS的业务数据。在LTE中,SC-MTCH的调度信息可以包括但不限于:调度周期、起始偏移,可能被调度的duration时间区间长度OnDurationTimer以及用户设备(UE)在成功接收到一个下行数据后等待的时间长度(drxInactivityTimerSCPTM)。图2是根据相关技术的LTE中SC-MTCH信道的调度方式示意图。如图2所示,eNB在SC-MTCH调度信息指定的资源内的任意一个无线子帧内均可调度承载特定MBMS业务的SC-MTCH的PDSCH信道,UE在成功接收到的该业务的一个下行数据后,继续等待上述drxInactivityTimerSCPTM时间长度,直到该时间超时或接收到该业务的一个新的数据。eNB使用组无线网络临时标识(G-RNTI)对调度SC-MTCH的PDCCH的DCI进行加扰,每个MBMS业务分配有单独的G-RNTI。
然而,当窄带物联网(NB-IoT)或增强机器间通信(eMTC)中引入SC-PTM时,将存在如下的问题:
图3是根据相关技术的LTE中会话停止的过程示意图。如图3所示,在SC-PTM中,正在发送中的MBMS业务的调度信息在SC-MCCH消息中指示给UE,如果一个MBMS业务会话停止时,核心网首先停止发送业务数据(发送完毕),然后核心网网元将MBMS会话停止(MBMS session stop)消息发送到接入网网元,接入网网元在下一个修改周期中,将相应业务的调度信息从SC-MCCH消息中移除,并通过SC-MCCH变更通知指示SC-MCCH消息的内容发生了变化,或UE在接收业务过程中的每个SC-MCCH修改周期的开始主动接收SC-MCCH消息。这样,在SC-MCCH消息中相应的MBMS业务的调度信息被移除时,UE能够获知该业务已经结束调度,因而停止尝试接收该业务的SC-MTCH信道的调度。
但是,在NB-IoT或eMTC中,为了实现UE省电,其系统消息的修改周期最长可达3个小时之久。相应地,SC-MCCH信道的修改周期可能需要和系统消息的修改周期保持一致或者同样为达到UE省电的目的,需要将SC-MCCH的修改周期长度配置为较长的时间。那么,这意味着一个业务在停止时,UE需要一段较长的时间才能从SC-MCCH消息的变更中获得该业务停止的指示。而在此之前,即便核心网已经停止了发送业务数据,UE仍然在每个SC-MTCH的调度周期中尝试接收SC-MTCH的调度。考虑到SC-MCCH修改周期最长可能长达3个小时,在此过程中,UE没有必要的尝试接收SC-MTCH调度会造成UE大量的电池消耗。
针对上述的问题,目前尚未提出有效的解决方案。
