Abstract

Description

信息处理方法及装置、通信设备及存储介质 技术领域
本公开涉及无线通信技术领域但不限于无线通信技术领域,尤其涉及一种信息处理方法及装置、通信设备及存储介质。
背景技术
第五代移动通信(5 th Generation,5G)核心网络支持用户终端通过卫星接入网络。
如果使用卫星接入为用户设备(User Equipment,UE)提供网络服务,卫星接入可能受星链中的卫星数量不足或者卫星波束间断等影响,向地面提供的覆盖可能是非连续的。即用户在某一区域通过卫星接入网络时,存在特定时间段无卫星信号覆盖的情况。
因此UE在接入网络以及开展业务的过程中,需要考虑卫星接入的非连续性覆盖,比如让UE在未有信号覆盖时,处于休眠或节电状态,以节省终端功耗,当卫星信号恢复覆盖的时候,UE及时唤醒重新和网络建立连接,或者开展业务。
再比如,网络侧如果需要向UE发送下行信令或下行数据的时候,需要判断此刻UE是否有卫的信号覆盖。
如果有卫星信号的覆盖,则将所述信令/数据发送给UE。
如果未有卫星信号的覆盖,则网络侧需要缓存所述信令/数据,在判断卫星信号恢复对所述UE的覆盖时,在将所述信令/数据发送给UE。
总之,在UE使用卫星接入网络,并且卫星接入存在非连续覆盖的情况下,UE和网络侧在发生信令/数据时,都需要结合卫星覆盖情况判断UE是否处于卫星信号覆盖下,只有在有信号覆盖下才进行通信交互。
上述方案实现了当UE处于无卫星信号覆盖的情况下,UE将保持在空闲状态,既保证了UE卫星信号覆盖恢复时,UE可以立即可从空闲状态转换到连接态,并快速开展业务,又实现了在无信号覆盖期间节省终端功耗的目的。
但是如果信号无覆盖时间过长,例如,UE获得20分钟所述卫星接入信号覆盖后间隔10小时才能再次获得20分钟信号覆盖,这就意味着在10小时之内UE保持休眠状态,无法开展业务。

请参考图1,其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示,无线通信系统是基于蜂窝移动通信技术的通信系统,该无线通信系统可以包括:若干个UE 11以及若干个接入设备12。
其中,UE 11可以是指向用户提供语音和/或数据连通性的设备。UE 11可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,UE 11可以是物联网UE,如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网UE的计算机,例如,可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如,站(Station,STA)、订户单元(subscriber unit)、订户站(subscriber station)、移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程UE(remote terminal)、接入UE(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户UE(user equipment,UE)。或者,UE 11也可以是无人飞行器的设备。或者,UE 11也可以是车载设备,比如,可以是具有无线通信功能的行车电脑,或者是外接行车电脑的无线通信设备。或者,UE 11也可以是路边设备,比如,可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
接入设备12可以是无线通信系统中的网络侧设备。其中,该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication,4G)系统,又称长期演进(Long Term Evolution,LTE)系统;或者,该无线通信系统也可以是5G系统,又称新空口(new radio,NR)系统或5G NR系统。或者,该无线通信系统也可以是5G系统的再下一代系统。其中,5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network,新一代无线接入网)。或者,MTC系统。
其中,接入设备12可以是4G系统中采用的演进型接入设备(eNB)。或者,接入设备12也可 以是5G系统中采用集中分布式架构的接入设备(gNB)。当接入设备12采用集中分布式架构时,通常包括集中单元(central unit,CU)和至少两个分布单元(distributed unit,DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层、无线链路层控制协议(Radio Link Control,RLC)层、媒体访问控制(Media Access Control,MAC)层的协议栈;分布单元中设置有物理(Physical,PHY)层协议栈,本公开实施例对接入设备12的具体实现方式不加以限定。

如图2所示,本公开实施例提供一种UE的接入网络切换方法,其中,由第一网元执行,所述方法包括:
S1110:在UE离开第一接入网络覆盖之前,将所述UE切换到第二接入网络;所述第二接入网络不同于所述第一接入网络;其中,所述第一接入网络为:卫星接入网络。
此处第一网元可为核心网网元,示例性地,该第一网元可包括:AMF和/或MME。
总之,所述第一网元可为对UE的接入和/或移动性管理的网元。
第一接入网络为UE当前的接入网络。
所述第一接入网络为NTN接入网络。该第一接入网络又可以称为卫星接入网络。例如,该卫星接入网络的使用非同步卫星时,卫星对地移动,此时UE自身的移动速率相对于卫星移动速率而言就可能忽略不计了。在非连续覆盖场景下,则UE会离开第一接入网络的网络覆盖,若UE离开了第一接入网络的网络覆盖,则不可以再继续通过第一接入网络通信。
非连续覆盖场景可为:星链中的卫星个数不够,导致在地面上某一个区域不能连续获得卫星接入网络的网络覆盖。本公开实施例提到的网络覆盖可以理解为网络信号的覆盖。例如,卫星发射的卫星信号的覆盖,基站发射的基站信号的覆盖。
在本公开实施例中,为了解决非连续覆盖场景下导致的UE失去网络覆盖的通信中断状态,会在UE离开第一接入网络覆盖之前,将UE切换到第二接入网络,如此,UE在失去第一接入网络覆盖之后,可以继续获得第二接入网络的网络覆盖,并通过第二接入网络进行通信。
在本公开实施例中,所述在UE离开第一接入网络覆盖之前,将所述UE切换到第二接入网络可以理解为:UE在失去第一接入网络覆盖之前,将所述UE切换到第二接入网络。

例如,所述第一接入网络为NTN接入网络,而所述第二接入网络TN接入网络。或者,所述第一接入网络可为NTN接入网络,而所述第二接入网络可为不同于第一接入网络的其他接入类型的NTN接入网络。
总之,所述S1110可包括:在UE离开第一接入网络之前,控制或触发UE进行跨网络切换,从 而通过这种跨网络切换,使得UE可以在单一接入网络的非连续覆盖场景下获取到连续的网络覆盖,确保随时并及时满足UE的通信需求。

所述UE的位置信息包括但不限于:UE的经纬度等表示UE所在位置的任意信息。该UE的位置信息可包括UE自身上报的位置信息。
在一些示例中,该UE的位置信息可为UE上报且通过网络验证的可信位置信息。网络验证UE的位置信息的方式有种,此处就不展开一一描述了。
在一个实施例中,该星历信息可至少包括:第一接入网络涉及的卫星的星历信息。
在另一个实施例中,第一网元可根据第一网元获取的所有接入网络的卫星的星历信息。
根据星历信息以及UE的位置信息,确定UE离开第一接入网络覆盖的时刻,如此在该时刻之前,使得UE切换到第二接入网络。此处,UE离开第一接入网络覆盖的时刻即为前述第一时刻。
在一些实施例中,所述第一接入网络和所述第二接入网络为不同运营商的网络。
在另一个实施例中,所述第一接入网络和所述第二接入网络为相同运营商的网络。
若第一接入网络和第二接入网络为不同运营商的网络,则不同运营商的网络使用的接入技术可以相同或者不同。例如,有的接入网络使用的是蜂窝小区接入技术,而有的接入网络使用的卫星接入技术。所述蜂窝小区接入技术又可以细分为:使用新无线(New Radio,NR)接入技术和/或长期演进(Long Term Evolution,LTE)接入技术。
所述卫星接入技术可以根据使用卫星的运行轨道不同进行区分,例如,低轨(Low Earth Orbit,LEO)卫星、中轨(Medium Earth Orbit,MEO)卫星和静止轨道(Geosynchronous Earth Orbit,GEO)卫星。此处的静止轨道卫星也即地球的同步卫星。
若第一接入网络和第二接入网络属于相同的运营商,则通常第一接入网络和第二接入网络使用的接入技术不同。
此处的运营商为通信网络的运营商。
在一些实施例中,所述方法还包括:

示例性地,可以根据星历信息以及UE的位置信息,确定在UE离开第一接入网络覆盖时能够可供UE接入的卫星接入网络。
若在UE离开第一接入网络覆盖时没有可供UE接入的其他卫星接入网络,可以确定可供UE接入的TN接入网络。
当然在另一个实施例中,若根据星历信息以及UE的位置信息确定出UE即将离开第一接入网络覆盖时,直接根据UE的位置信息确定可供UE接入的TN接入网络。
在一些实施例中,根据星历信息以及所述UE的位置信息,确定供所述UE接入的所述第二接入网络,包括:

又示例性地,根据UE的位置信息和多个接入网络的星历信息,可以大致确定出可供UE接入的一个或多个NTN网络,此时,将一个或多个NTN网络的MME或者AMF等确定为第二网元,然后又请求第二网元确定出精确可供UE接入的第二接入网络。
该请求消息可为任意第一网元和第二网元之间可以相互传输的消息。
示例性地,该请求消息包括但不限于:重定向请求消息,该重定向请求消息可用于UE的重定向,在本公开实施例中,可用于UE跨网络的接入切换。
若第二网元确定出可供UE接入的第二接入网元之后,会将第二接入网的接入网元的标识(即网元标识)返回给第一网元,后续第一网元可根据第二接入网络的接入网元的标识,在UE离开第一接入网络覆盖之前发送切换指令,使得UE实现跨网络的小区切换。
若所述请求消息为重定向请求消息,则所述响应消息可为:重定向响应消息。
如图4所示,本公开实施例提供一种UE的接入网络切换方法,其中,由第一网元执行,所述方法包括:

在另一个实施例中,若UDM和/或HSS发送UE签约的接入网络有变化时,主动向第一网元推送UE签约的接入网络的信息。
在一些实施例中,所述星历信息为多个接入网络的星历信息。

该运营商商策略为TN接入网络优先策略,则会在有可供UE接入的TN接入网络时,会将第二接入网络确定为可供UE在失去第一接入网络覆盖时接入TN网络。
当然以上仅仅是运营商策略的举例说明,具体实现时不局限于上述举例。
在一些实施例中,所述方法还包括:
获取所述UE签约的接入网络的信息。
示例性地,所述获取所述UE签约的接入网络的信息可包括:
从归属签约用户服务器HSS或统一数据管理UDM中,获取所述UE签约的接入网络的信息。
在一个实施例中,第一网元向UDM或者HSS发送UE签约的接入网络的信息的请求,则第一网元将接收到UDM或者HSS返回的UE签约的接入网络的信息。
在另一个实施例中,若UDM和/或HSS发送UE签约的接入网络有变化时,主动向第一网元推送UE签约的接入网络的信息。在另一个实施例中,第二网元还可以根据UE的位置信息和NTN的卫星的星历信息,确定出可供UE的第二接入网络即接入网元,此时该第二接入网络为卫星接入网络。

该第一接入网络和第二接入网络为不同的网络,如此实现UE的跨接入网络的切换。且该切换指令可为UE即将离开第一接入网络覆盖之前接收到的。
在一个实施例中,所述S3210:在离开所述第一接入网络的覆盖之前,根据所述切换指令,接入到第二接入网络。
在一些实施例中,所述切换指令还包括:
接入所述第二接入网络的无线参数。
该无线参数可供UE接入第二接入网络的任意参数。
在一些实施例中,所述方法还包括:

在接收到所述接入成功消息之后,释放通过所述第一接入网络建立的连接。
在接入到第二接入网络之后,才释放通过所述第一接入网络建立的连接,如此至少保证UE一个时刻至少有一个接入网络供其接入,从而确保UE通信和业务连续性。
本公开实施例提供了另一种解决卫星非连续性覆盖问题的技术方案,当UE在失去当前卫星接入信号覆盖期间,通过接入其他可用的接入网络,继续使用网络服务,这样一方面可以缩短因为当前卫星接入的非连续性覆盖致使UE无法使用网络服务的时间,另一方面也有利于保持UE正在开展业务的连续性。
例如,UE正在使用卫星运营商A(Satellite Operator,SO)的接入网络A接入并开展业务,由于卫星移动,当接入网络A对所述UE所在区域的覆盖即将丢失的时候,UE可快速切换到接入网络B,从而可以在接入网络A不对所述UE所在区域提供覆盖的时候,所述UE可以使用接入网络B并继续开展业务。
所述接入网络B可同样是卫星接入网络。例如,卫星A是LEO,所述卫星B是GEO。
或者,
所述接入网络B可以是其他SO提供的卫星接入网络,所述接入网络B与接入网络A的接入类型可以相同或者不同。
例如,接入网络A和接入网络B可为不同运营商提供的LEO,或者接入网络A是LEO,接入网络B是GEO。
所述接入网络B也可以是地面蜂窝接入网络,例如,LTE或NR等。
假设UE支持多种接入网络的接入,则UE可以在多个接入网络之间切换。
第一网元确定发起跨接入网络的切换的原因可如下:
第一网元在收到来自UE或第一接入网络的接入网元的切换请求,或者,第一网元根据星历信息确定UE即将失去第一接入网络的覆盖,需要为所述UE发起跨接入网络的切换。
所述第一网元为切换前向UE提供服务的核心网的网元,如MME,AMF
根据星历信息确定第一接入网络对所述UE位置所在区域即将失去覆盖时,确定发起跨接入网络的切换。第一接入网络可为卫星接入网络。
在一个实施例中,确定发起跨接入网络的切换之后,根据第一信息确定可用第二接入网络及对应的第二网元。此处第一信息可以参见前述对应实施例处,此处就不再重复了。
所述第二接入网络可以为:区别于当前卫星接入运营商的其他卫星接入运营商的卫星接入网络。
或者,
第二接入网络,可为:为同一卫星接入运营商的区别于第一接入网络的第二接入网络。所述第一接入网络和第二接入网络可为不同的接入类型。例如,第一接入网络的接入类型可为LEO,第二接入网络的接入类型可为MEO。
所述第一网元根据星历信息选择所述第二网元,并发起切换请求。
所述第二网元根据星历信息选择第二接入网络的接入网元。所述第二网元,将所述第二接入网络的接入网元的标识发送给所述第一网元。
在另一个实施例中,所述第一网元,根据星历信息确定发起跨接入网络的切换,向所述第二网元发起切换请求。
以UE在卫星运营商A的卫星接入网络LEO-A和卫星运营商B的卫星接入网络LEO-B之间切换为例。所述UE通过LEO-A和LEO-B都接入EPC。
所述第一接入网络的接入类型为LEO,第一接入网络的接入网元网元即源eNB,第一网元即源MME。所述第二接入网络的接入类型为LEO,第二接入网络的接入网元即目的eNB,第二网元为目的MME。
本公开实施例提供的UE的接入网络切换方法可包括:1.UE使用LEO-A接入到EPC。UE在源eNB、源服务网关(Serving Gateway,S-GW)和分组数据网网关(Packet Data Network Gateway,P-GW)之间进行业务数据交互。此时根据星历信息判断所述LEO-A即将失去对UE所在区域的覆盖,决定将所述UE切换至其他可用接入网络,该切换过程可以通过如下过程实现:
1a.源MME确定为UE发起跨接入网络的切换,该过程可包括:
(1)UE或者源eNB根据星历信息判断所述UE即将失去LEO-A的覆盖,向源MME发起切换请求消息。
(2)源MME根据星历信息判断所述UE即将失去LEO-A的覆盖,确定发起UE的跨网络的接入切换。
1b.源MME从HSS获取UE签约的接入网络的信息。如果签约接入网络中有卫星接入网络,还需要获取与所述卫星接入网络对应的星历信息。
1c.根据UE签约的接入网络信息、运营商策略和/或签约卫星接入网络对应的签约数据,选择可用的接入网络。根据所述可用的接入网络的信息,选择目的MME。本实施例中选择的可用接入网络为LEO-B。
2.源MME向目的MME发送转发重定位请求(Forward Relocation Request),携带UE的国际移动用户识别码(International Mobile Subscriber Identification Number,IMSI)等UE的标识,移动性管理上下文,公共数据网络(Public Data Network,PDN)连接信息以及UE的位置信息等。
3.目的MME接收所述重定位请求后,根据星历信息、UE位置信息等确定覆盖UE所在区域的目的eNB。
4.如果UE的S-GW需要重定位(例如服务PLMN发生了变化),目的MME选择目的S-GW,并发起会话建立过程(create session request/response)。例如,UE的公共陆地网络(Public land mobile network,PLMN)发生了变化,则需要重新确定UE的S-GW,否则无需重新确定UE的S-GW。
5.目的MME向目的eNB发送重定位请求(Relocation request),该重定位请求用于建立无线连接预留网络资源。该预留网络资源的资源参数为前述携带在响应消息中的一种无线参数。
6.如果使用间接数据转发模式,目的MME还需要给目的S-GW发送间接数据转发隧道建立请求(Create Indirect Data Forwarding Tunnel Request)。目的S-GW会向目的MME返回间接数据转发隧道建立请求的响应。
7.目的MME向源MME返回转发重定位响应(Forward Relocation Response)消息,在所述重定位响应消息中包含目的eNB的标识。
8.与步骤6对应,源MME和源S-GW交互,完成间接数据转发隧道建立。此时完成了UE准备由LEO接入向MEO接入切换的准备。LEO接入(源eNB)仍然接收上下行数据。
9.源MME向源eNB发起切换指令(Handover command)。源eNB向UE发送切换指令,该切换指令要求UE切换至目的接入网络(MEO)。该切换指令包含一个透明容器(transparent container)。所述透明容器包含有切换准备阶段(步骤1-8)目的eNB建立的无线参数。例如该无线参数可包括前述预留网络资源的资源参数。
10.如果PLMN配置了第二接入数据使用报告(Secondary RAT usage data report),源eNB发送数据上报消息。
11.UE执行切换,根据步骤9提供的相关无线参数,接入至MEO(即目的eNB),完成到MEO的接入过程。
此时UE可以使用MEO发送上行数据。对于下行数据,如果使用了数据直接转发模式,则可由源eNB直接转发给目的eNB后发送给UE。
如果使用了数据间接转发模式,则源eNB接收下行数据后发送给源S-GW,由源S-GW发送目的S-GW,再由目的S-GW发送给目的eNB后发送给UE。
12.目的eNB给目的MME发送重定位完成消息(Relocation Complete),指示完成了从LEO到MEO的重定位。
13.目的MME知道UE已经通过MEO接入,向源MME发送转发重定位完成通知(Forward Relocation Notification).
14.目的MME完成切换过程,向目的S-GW发起承载修改过程(Modify Bearer Request),通知目的S-GW,由目的MME负责UE所有已经建立的演进分组系统(Evolved Packet System,EPS)承载(bearer)上下文。目的S-GW发起到P-GW的承载修改过程,并将RAT-TYPE为MEO通知给P-GW,以便更改计费策略。
此时UE可以使用MEO接入进行上、下行数据的交互。
15.如果此时UE识别到当前位置不在广播跟踪区(Tracking Area,TA)内,发起路由区更新(Routing Area Update)过程。
16.源MME收到步骤13的重定位完成消息,就可以发起和源S-GW,源eNB的会话和连接释放。
17.源MME和源S-GW、目的MME和目的S-GW之间释放间接数据转发通道。
