具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
应理解,本发明的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access, CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、先进的长期演进(Advanced long term evolution,LTE-A)系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、新空口(New Radio,NR)等。
还应理解,在本发明实施例中,用户设备(User Equipment,UE)包括但不限于移动台(Mobile Station,MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等,该用户设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,例如,用户设备可以是移动电话(或称为“蜂窝”电话)、具有无线通信功能的计算机等,用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。
在本发明实施例中,基站(例如,接入点)可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换,作为无线终端与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)网络。基站还可协调对空中接口的属性管理。例如,基站可以是GSM或CDMA中的基站(Base Transceiver Station,BTS),也可以是TD-SCDMA或WCDMA中的基站(NodeB),还可以是LTE中的演进型基站(eNodeB或eNB或e-NodeB,evolutional Node B),或者是5G NR中的基站(gNB),本发明并不限定。
本申请实施例提供了信息处理方法及装置、计算机存储介质,用以实现基于终端的移动性相关信息,进行针对所述终端的移动性管理参数的设置,从而能够利用终端的移动性行为分析结果来进行注册区域管理和可达性管理。
第五代(5G)网络需要支持按需移动性管理,即针对单个用户设备(User Equipment,UE)的移动行为特征等提供定制化的移动性管理服务,其中包括针对单个UE的注册区域管理和对UE的可达性管理,这要求5G网络能够获取对UE移动行为的分析然后进行移动性管理机制的定制。在5G阶段1(phase 1),5G网络中引入了NWDA功能,该功能能够对网络数据进行分析,然后向5G网络提供分析结果,使得5GC能够进行网络优化。然而,目前的NWDA功能只用于切片相关的网络数据分析,却没有对UE移动性行为进行分析,因此本申请实施例提出了基于NWDA提供的UE移动性行为分析结果进行UE的注册区域管理和可达性管理的技术方案。
首先,支持NWDA的5G策略控制和计费(PCC)网络架构,参见图1,该架构中,网络数据分析功能(Network Data Analytic Function,NWDAF)是运营商管理的网络分析功能,NWDAF提供切片相关的网络数据分析给分组控制功能(Packet Control Function,PCF)和网络切片选择功能(Network Slice Selection Function,NSSF)。所提供的网络数据分析是 网络切片级别的,并且NWDAF不需要感知当前使用切片的用户。NWDAF向订阅了数据分析的PCF和NSSF通知或推送切片相关的网络状态分析信息。PCF和NSSF可以直接从NWDAF获取。
关于本申请实施例中所述的注册区域管理:
注册区域管理功能主要指为用户设备(User Equipment,UE)分配和重分配注册区域。当UE通过第三代合作伙伴计划(3GPP)接入注册到网络后,AMF为UE分配跟踪区标识(Tracking Area identity,TAI)列表(list),TAI list中包括一组跟踪区(Tracking Area,TA)区域。接入和移动性管理功能(AMF)实体,在分配注册区域时需要考虑对终端的移动性限制信息和移动性模型信息。当UE通过非3GPP(non-3GPP)接入到网络后,全网使用唯一的TA,此时AMF会在TAI list中仅包括该唯一的TA。
关于本申请实施例中所述的可达性管理:
当UE进入空闲(CM-IDLE)态后,UE会根据注册过程中收到的周期性注册定时器值来启动定时器,该定时器值是AMF根据UE签约、本地策略等确定的。UE在周期性注册定时器超时后会发起周期性注册更新过程。
AMF会运行移动可达定时器。该定时器(timer)在UE进入CM IDLE态后开始运行,其值略大于周期性注册定时器的值。在移动可达定时器运行期间,如果UE进入了连接(CONNECTED)状态,则AMF将停止该移动可达定时器。如果移动可达定时器超时,AMF就可以确定UE不可达。由于AMF不知道UE何时会可达,因此AMF并不能立刻去注册UE,而是在移动可达定时器超时后,AMF清除PPF标识,并且使用相对更大的值启动隐式去注册定时器。当UE状态变为连接态后,AMF需停止隐式去注册定时器并设置PPF标识。
下面分别给出本申请实施例提供的两种具体方法的举例说明。
方法一:
PCF根据NWDAF提供的终端的移动性行为信息(又可称为移动性分析/预测信息),例如UE的移动模式(mobility pattern),终端的历史位置统计信息,终端移动轨迹的预测信息等,确定移动性管理策略(mobility management policy,简称MM policy)信息,其中可以包括终端的移动性管理参数,还可以进一步包括终端的移动性管理参数的使用条件。其中,所述的UE的移动模式,例如包括UE的移动速度、方向等。
其中,所述终端的移动性管理参数,例如包括:
推荐的注册区域(recommended registration area);
和/或,推荐的周期性注册定时器值(recommended periodic registration timer value)。
所述使用条件,例如至少包括如下信息之一:
所述终端的标识信息;
所述终端的位置或区域信息;
日期和/或时间信息。
PCF确定了mobility management policy后,向AMF提供mobility management policy;
AMF在分配registration area,periodic registration timer时,可以参考mobility management policy。
下面给出方法一的具体的两个实施例。
实施例1:基于MM policy进行注册区域管理(registration area management)。
参见图2,具体的处理流程包括:
步骤1.PCF从NWDAF接收UE mobility pattern等UE的移动性相关信息;
步骤2.PCF根据UE mobility pattern、PCF本地配置的运营商策略等,确定UE在特定区域的注册区域信息,即确定该UE的推荐的注册区域(recommended registration area)的信息,其中,注册区域包括一组TA或者小区列表(cell list)的信息。所述特定区域可能以地理区域(geographical area)的形式表示,因此PCF可能需要进行geographical area到TA或者cell list的映射,也就是说,将UE的geographical area的信息转换成TA或者cell list的信息,具体的转换方式可以采用现有技术,从而,为UE生成recommended registration area;
步骤3.PCF向AMF发送MM policy,其中携带生成的recommended registration area,还可能包括该recommended registration area的使用条件,其中,所述使用条件,例如使用该recommended registration area的时间、地点等相关的限制条件;
下面的步骤A和步骤B是二选一的步骤。
步骤A:
步骤4a、AMF接收MM policy后,根据该MM policy发现连接态UE进入了recommended registration area且满足使用条件,则执行步骤4b。

步骤B:
步骤5a.AMF接收空闲态UE的注册请求(registration request);
步骤5b.AMF确定MM policy满足其使用条件,例如确定UE在合适的时间段进入了recommended registration area。

步骤32.PCF根据UE mobility pattern、运营商策略等,确定UE在特定位置区域和/或特 定时间段内所使用的推荐的周期性注册定时器值(recommended registration timer value),然后PCF生成MM policy,包含所确定的推荐的周期性注册定时器值及其使用条件,其中,所述使用条件,例如时间、地点等。
步骤33.PCF向AMF发送MM policy,AMF接收并保存MM policy;
步骤34.AMF接收空闲态UE的注册请求(registration request);
步骤35.AMF根据MM policy,若发现UE发送注册请求时所在的位置或者时间点,满足MM policy中携带的推荐的周期性注册定时器的使用条件,则AMF为UE确定新的周期性注册定时器值,即将MM policy中携带的推荐的周期性注册定时器值更新给UE;
步骤36.AMF将新的周期性注册定时器值(即步骤32中确定的周期性注册定时器值),通过注册接受(Registration Accept)消息通知UE。
另外,还可以有可选步骤(图中未体现),例如AMF可能在UE进入连接态后,向接入网节点发送该周期性注册定时器值,使得接入网节点根据新的周期性注册定时器值进行UE的可达性监测和管理(可达性监测和管理为现有技术)。
方法二:
AMF根据NWDAF提供的终端的移动性行为信息(可以是历史信息或预测信息,因此,又可称为移动性分析/预测信息),例如UE的移动模式(mobility pattern),确定移动性管理策略(mobility management policy,简称MM policy)信息,其中可以包括终端的移动性管理参数,还可以进一步包括终端的移动性管理参数的使用条件。

AMF在判断UE满足使用recommended registration area、recommended periodic registration timer value的条件时,为UE分配对应的recommended registration area或periodic registration timer。
实施例3.基于NWDAF的输出进行注册区域管理。
参见图4,具体的处理流程包括:
步骤41.AMF从NWDAF接收网络数据分析结果,包括UE mobility pattern等;
步骤42.AMF根据UE mobility pattern、运营商策略等,确定UE在特定位置的推荐的注册区域信息,生成recommended registration area以及该recommended registration area的使用 条件,其中,recommended registration area由一组TA或者cell list组成;所述特定位置可以是地理位置。
下面的步骤A和步骤B是二选一的步骤。

步骤53.AMF接收空闲态UE的注册请求(registration request);
步骤54.AMF根据MM policy,若发现UE发送请求时所在的位置或者时间点满足新的周期性注册定时器的使用条件,则AMF为UE确定新的周期性注册定时器值(步骤52中确定的周期性注册定时器值),即将MM policy中携带的推荐的周期性注册定时器值更新给UE;
步骤55.AMF将新的周期性注册定时器值(即步骤52中确定的周期性注册定时器值),通过注册接受(Registration Accept)消息通知UE。
另外,还可以有可选步骤(图中未体现),例如AMF可能在UE进入连接态后,向接入网节点发送该周期性注册定时器值,使得接入网节点根据新的周期性注册定时器值进行UE的可达性监测和管理(可达性监测和管理为现有技术)。
