Abstract

本发明公开了一种上下文标识的指示方法、获取方法、用户设备(UE)、基站及计算机存储介质,其中方法包括:在MSG3消息中,携带部分UE上下文标识信息、以及针对第二基站的标识信息的相关信息;发送所述MSG3消息至第一基站。

Description

上下文标识的指示方法、获取方法、用户设备及基站 技术领域
本发明涉及信息处理技术领域,尤其涉及一种上下文标识的指示方法、获取方法、用户设备(UE)、基站及计算机存储介质。
背景技术
当前,随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性,为此3GPP国际标准组织开始研发5G。5G网络环境中为了降低空口信令和快速恢复无线连接,快速恢复数据业务的目的,定义了新的RRC状态,即RRC_INACTIVE状态。这种状态有别于RRC_IDLE和RRC_ACTIVE状态。当网络侧命令UE进入RRC_INACTIVE状态时,网络侧会给UE分配一个标识,该标识用于标识UE的上下文,同时也为了寻址保存UE上下文的gNB,同时网络侧会将这个标识以及寻呼区域等信息配置给UE。当UE恢复连接时,通过MSG3发给网络侧,该消息携带UE上下文标识来通知网络侧进行上下文获取以及寻址保存上下文的gNB。
但是,当前MSG3的大小按照48bit设计,如果还是按照40bit标识来设计的化,MSG3的大小会变大,所以基站在MSG2中的grant需要总是分配80bit大小的来分配UL grant(传统56bit)。可以看出,现有技术中,MSG3无法降低信令负荷、以及会造成一定程度上的资源浪费。

具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容,下面结合附图对本发明实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本发明实施例。
实施例一、
本发明实施例提供了一种上下文标识的指示方法,应用于UE,如图1所示,包括:
步骤101:在MSG3消息中,携带部分UE上下文标识信息、以及针对第二基站的标识信息的相关信息;
步骤102:发送所述MSG3消息至第一基站。
这里,所述UE可以为智能手机、平板电脑等能够接入移动通信网的设备。
执行步骤101之前,即所述在MSG3消息中,携带部分UE上下文标识信息、以及针对第二基站的标识信息的相关信息之前,所述方法还包括:
获取所述第二基站的标识信息与第一基站的标识信息之间的差值;
判断所述差值是否大于预设值。
具体来说,判断所述差值是否大于预设值之后,当所述差值不大于所述预设值时,将所述第二基站的标识信息与第一基站的标识信息之间的差值,以及所述第二基站的标识信息与第一基站的标识之间的大小关系,作为所述针对第二基站的标识信息的相关信息。
其中,所述第一基站可以理解为UE当前所在基站,也就是当前为UE提供服务的基站;第二基站则为UE上下文信息中记录的基站。
也就是说,当前基站与记录的基站的标识信息之间的差值小于一定值的时候,能够在MSG3中设置全部的信息,此时可以将差值及其对应的关系全部放在MSG3中。
其中,所述预设值可以为根据实际情况进行设置,具体的跟能设置多长的数据位相关,若数据位有4个bit用于表示差值,那么预设值就可以设置为16,也就是说,超过16的话,就必须有5个bit及以上来表示了。
具体来说,判断所述差值是否大于预设值之后,当所述差值大于所述预设值时,将针对所述第二基站的标识信息的位置指示信息作为所述针对第二基站的标识信息的相关信息;
其中,所述针对所述第二基站的标识信息的位置指示信息至少用于指示针对所述第二基站的标识信息在MSG5中发送。
这种场景下,也就是说,部分UE上下文标识信息,和/或第二基站的标识信息可以携带在MSG5中发出,具体的:在MSG5中,携带针对所述 第二基站的标识信息,和/或所述部分UE上下文标识信息;
发送所述MSG5至所述第一基站。
可以看出,通过UE在MSG3中指示部分上下文信息,以及针对第二基站的标识信息的相关信息,让当前基站获取UE完整的上下文信息,进而能够进行上下文获取以及对保存上下文基站的寻址,以便于进行RRC连接恢复。达到降低信令负荷、避免资源浪费的目的。
实施例二、
本发明实施例提供了一种上下文标识的获取方法,应用于第一基站,如图2所示,包括:
步骤201:接收UE发来的MSG3消息;
步骤202:从所述MSG3消息中,获取部分UE上下文标识信息、以及针对第二基站的标识信息的相关信息。
这里,所述UE可以为智能手机、平板电脑等能够接入移动通信网的设备。
相对应于实施例一提供的两种设置针对第二基站的标识信息的相关信息的方式,本实施例也同样具备多种解析方式:
第一种方式,就是在MSG3中包含有差值以及大小关系的处理方式:
所述从所述MSG3消息中,获取部分UE上下文标识信息、以及针对第二基站的标识信息的相关信息,包括:
从所述MSG3消息中,获取部分UE上下文标识信息、所述第二基站的标识信息与第一基站的标识信息之间的差值、以及所述第二基站的标识信息与第一基站的标识之间的大小关系;
基于所述部分UE上下文标识信息、所述第二基站的标识信息与第一基站的标识信息之间的差值、以及所述第二基站的标识信息与第一基站的标识之间的大小关系,确定所述第二基站的标识信息。
其中,所述第一基站可以理解为UE当前所在基站,也就是当前为UE提供服务的基站;第二基站则为UE上下文信息中记录的基站。
也就是说,当前基站与记录的基站的标识信息之间的差值小于一定值的时候,能够在MSG3中设置全部的信息,此时可以将差值及其对应的关系全部放在MSG3中。
其中,所述预设值可以为根据实际情况进行设置,具体的跟能设置多长的数据位相关,若数据位有4个bit用于表示差值,那么预设值就可以设置为16,也就是说,超过16的话,就必须有5个bit及以上来表示了。
第二种方式、在MSG3中获取指示信息,然后从MSG5中获取具体的标识信息。
具体来说,判断所述差值是否大于预设值之后,当所述差值大于所述预设值时,将针对所述第二基站的标识信息的位置指示信息作为所述针对第二基站的标识信息的相关信息;
其中,所述针对所述第二基站的标识信息的位置指示信息至少用于指示针对所述第二基站的标识信息在MSG5中发送。
从所述MSG3消息中,获取部分UE上下文标识信息、针对所述第二基站的标识信息的位置指示信息;其中,所述针对所述第二基站的标识信息的位置指示信息至少用于指示针对所述第二基站的标识信息在MSG5中发送。
这种场景下,也就是说,部分UE上下文标识信息,和/或第二基站的标识信息可以携带在MSG5中发出,具体的:在MSG5中,携带针对所述第二基站的标识信息,和/或所述部分UE上下文标识信息;发送所述MSG5至所述第一基站。相应的,基站侧:所述接收UE发来的MSG3消息之后,所述方法还包括:
在MSG5中,获取针对所述第二基站的标识信息,和/或所述部分UE 上下文标识信息。
所述获取所述第二基站的标识信息之后,所述方法还包括:
基于所述第二基站的标识信息获取所述UE的上下文信息。
本实施例结合图3提供一种具体的实时流程,首先,设计UE上下文ID不考虑MSG3大小限制,例如仍然为40bit,20bit基站ID+20bit上下文ID,然后执行以下处理:
1、当UE进入inactive状态时,网络侧配置UE上下文ID和寻呼区域等信息。
2、当inactive UE发起RRC连接恢复时,MSG3消息中携带上下文标识,例如步骤1中的20bit,以及当前基站的基站ID和保存上下文基站的基站ID之间差值上报给网络侧,例如该差值在MSG3中用4bit表示。同时指出当前基站的基站ID和保存上下文基站的基站ID是大于关系还是小于关系。
3、如果当前基站的基站ID和保存上下文基站的基站ID之间差值大于16,不能用4个bit表示时,则在MSG3中携带UE上下文标识,而是在MSG3中添加一个指示,指示网络侧上下文标识将在MSG5中携带给网络侧。
4、获取到UE上下文标识后,获取UE上下文,建立专用承载,进行业务数据发送和接收。
可以看出,通过UE在MSG3中指示部分上下文信息,以及针对第二基站的标识信息的相关信息,让当前基站获取UE完整的上下文信息,进而能够进行上下文获取以及对保存上下文基站的寻址,以便于进行RRC连接恢复。达到降低信令负荷、避免资源浪费的目的。
实施例三、
本发明实施例提供了一种UE,如图4所示,包括:
第一处理单元41,在MSG3消息中,携带部分UE上下文标识信息、以及针对第二基站的标识信息的相关信息;
第一通信单元42,发送所述MSG3消息至第一基站。
这里,所述UE可以为智能手机、平板电脑等能够接入移动通信网的设备。
即所述在MSG3消息中,携带部分UE上下文标识信息、以及针对第二基站的标识信息的相关信息之前,所述第一处理单元41,获取所述第二基站的标识信息与第一基站的标识信息之间的差值;
判断所述差值是否大于预设值。
具体来说,判断所述差值是否大于预设值之后,当所述差值不大于所述预设值时,将所述第二基站的标识信息与第一基站的标识信息之间的差值,以及所述第二基站的标识信息与第一基站的标识之间的大小关系,作为所述针对第二基站的标识信息的相关信息。
其中,所述第一基站可以理解为UE当前所在基站,也就是当前为UE提供服务的基站;第二基站则为UE上下文信息中记录的基站。
也就是说,当前基站与记录的基站的标识信息之间的差值小于一定值的时候,能够在MSG3中设置全部的信息,此时可以将差值及其对应的关系全部放在MSG3中。
其中,所述预设值可以为根据实际情况进行设置,具体的跟能设置多长的数据位相关,若数据位有4个bit用于表示差值,那么预设值就可以设置为16,也就是说,超过16的话,就必须有5个bit及以上来表示了。
具体来说,判断所述差值是否大于预设值之后,第一处理单元41,当所述差值大于所述预设值时,将针对所述第二基站的标识信息的位置指示信息作为所述针对第二基站的标识信息的相关信息;
其中,所述针对所述第二基站的标识信息的位置指示信息至少用于指 示针对所述第二基站的标识信息在MSG5中发送。
这种场景下,也就是说,部分UE上下文标识信息,和/或第二基站的标识信息可以携带在MSG5中发出,具体的:在MSG5中,携带针对所述第二基站的标识信息,和/或所述部分UE上下文标识信息;
发送所述MSG5至所述第一基站。
可以看出,通过UE在MSG3中指示部分上下文信息,以及针对第二基站的标识信息的相关信息,让当前基站获取UE完整的上下文信息,进而能够进行上下文获取以及对保存上下文基站的寻址,以便于进行RRC连接恢复。达到降低信令负荷、避免资源浪费的目的。
实施例二、

第二通信单元51,接收UE发来的MSG3消息;
第二处理单元52,从所述MSG3消息中,获取部分UE上下文标识信息、以及针对第二基站的标识信息的相关信息。
这里,所述UE可以为智能手机、平板电脑等能够接入移动通信网的设备。
相对应于实施例一提供的两种设置针对第二基站的标识信息的相关信息的方式,本实施例也同样具备多种解析方式:
第一种方式,就是在MSG3中包含有差值以及大小关系的处理方式:
所述第二处理单元52,从所述MSG3消息中,获取部分UE上下文标识信息、所述第二基站的标识信息与第一基站的标识信息之间的差值、以及所述第二基站的标识信息与第一基站的标识之间的大小关系;
基于所述部分UE上下文标识信息、所述第二基站的标识信息与第一基站的标识信息之间的差值、以及所述第二基站的标识信息与第一基站的标识之间的大小关系,确定所述第二基站的标识信息。
其中,所述第一基站可以理解为UE当前所在基站,也就是当前为UE提供服务的基站;第二基站则为UE上下文信息中记录的基站。
也就是说,当前基站与记录的基站的标识信息之间的差值小于一定值的时候,能够在MSG3中设置全部的信息,此时可以将差值及其对应的关系全部放在MSG3中。
其中,所述预设值可以为根据实际情况进行设置,具体的跟能设置多长的数据位相关,若数据位有4个bit用于表示差值,那么预设值就可以设置为16,也就是说,超过16的话,就必须有5个bit及以上来表示了。
第二种方式、在MSG3中获取指示信息,然后从MSG5中获取具体的标识信息。
具体来说,判断所述差值是否大于预设值之后,当所述差值大于所述预设值时,将针对所述第二基站的标识信息的位置指示信息作为所述针对第二基站的标识信息的相关信息;
其中,所述针对所述第二基站的标识信息的位置指示信息至少用于指示针对所述第二基站的标识信息在MSG5中发送。
第二处理单元52,从所述MSG3消息中,获取部分UE上下文标识信息、针对所述第二基站的标识信息的位置指示信息;其中,所述针对所述第二基站的标识信息的位置指示信息至少用于指示针对所述第二基站的标识信息在MSG5中发送。
这种场景下,也就是说,部分UE上下文标识信息,和/或第二基站的标识信息可以携带在MSG5中发出,具体的:在MSG5中,携带针对所述第二基站的标识信息,和/或所述部分UE上下文标识信息;发送所述MSG5至所述第一基站。相应的,基站侧:第二处理单元52,所述接收UE发来的MSG3消息之后,所述方法还包括:

所述获取所述第二基站的标识信息之后,所述方法还包括:
