一种播发信息的方法及设备
相关申请的交叉引用
本公开要求在2019年08月12日提交中国专利局、申请号为201910741727.8、申请名称为“一种播发信息的方法及设备”的中国专利申请的优先权,其全部内容通过引用结合在本公开中。
技术领域
本发明涉及无线通信技术领域,特别涉及一种播发信息的方法及设备。
背景技术
新空口(New Radio,R16NR)定位中正在讨论如何实现基站侧广播定位辅助数据,目前基站侧广播定位辅助数据的方式为:定位管理实体(Location Management Function,LMF)实体将所需要广播的定位辅助数据发送给基站,基站将接收到的定位辅助数据存储,并将其通过系统消息(System Information,SI)广播下去,终端无线资源控制(Radio Resource Control,RRC)层接收到定位辅助数据的广播消息后,将所述定位辅助数据递交给非接入层(Non Access Stratum,NAS)层的长期演进定位协议(Long Term Evolution Positioning Protocol,LPP)进行处理。
NR广播定位辅助数据时,在NR SI中的每一个SI都有一个区域标识(area ID),其中area ID表示携带该area ID的SI中的定位辅助数据的有效区域。但是对于不同的定位系统,定位辅助数据的有效区域不同。比如辅助全球导航卫星定位系统(Assisted-Global Navigation Satellite System,A-GNSS)的定位辅助数据的有效区域可在几百公里之内,而根据NR广播定位辅助数据时SI中携带的area ID确定的有效区域较小,因此现有NR广播定位辅助数据时SI中携带的area ID对应的有效区域的大小不合适,而A-GNSS的定位辅助数据更新需要1秒的频度,因此需要终端持续监听基站的广播消息,以获取新的 定位辅助数据,终端耗电量大。

具体实施方式
以下,对本公开实施例中的部分用语进行解释说明,以便于本领域技术 人员理解。
(1)本公开实施例中,名词“网络”和“系统”经常交替使用,但本领域的技术人员可以理解其含义。
(2)本公开实施例中术语“多个”是指两个或两个以上,其它量词与之类似。
(3)“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
如图1所示为播发信息的应用场景结构图,具体的:
长期演进(Long Term Evolution,LTE)广播定位辅助数据时:定位服务器产生定位辅助数据的广播信息,并将定位辅助数据的广播信息通过LTE定位协议A(LTE positioning protocol A,LPPa)协议发送给基站,基站将定位辅助数据通过广播进行播发,终端的RRC接收到基站广播的定位辅助数据,将接收到的定位辅助数据递交给NAS层的LPP进行处理,RRC层确定接收到的定位辅助数据的类型,并将定位辅助数据传递给NAS层,并不会知道其他信息。
NR广播定位辅助数据时:定位服务器在向基站发送定位辅助数据,基站将接收到的定位辅助数据进行存储,并将接收到的定位辅助数据通过系统消息广播下去,在通过系统消息广播定位辅助数据时,携带area ID,来表示定位辅助数据在哪个区域内有效,但是area ID对应的辅助数据的有效区域与定位辅助数据的实际有效区域不同,area ID对应的辅助数据的有效区域小于定位辅助数据的实际有效区域,比如A-GNSS的定位辅助数据的有效区域在几百公里之内,与area ID对应的辅助数据的有效区域大小相差较大,且A-GNSS的定位辅助数据的更新大概在1秒的频度,终端持续监听广播来更新定位辅助数据,造成终端消耗电量大。
因此,本发明针对终端持续监听持续广播以更新定位辅助数据,提供一种播发信息的方法,来更新定位辅助数据,减小终端的耗电量,提高定位辅 助数据的有效性。本发明定位服务器在确定定位辅助数据后,确定定位辅助数据的有效区域及定位辅助数据的有效时间,并将定位辅助数据的有效区域、定位辅助数据的有效时间及定位辅助区域发送给基站,并通过基站将定位辅助数据的有效区域、定位辅助数据的有效时间及定位辅助数据播发下去。终端接收到定位辅助数据,接收到定位辅助数据的有效区域及定位辅助数据的有效时间,并根据定位辅助数据的有效区域及定位辅助数据的有效时间在确定需要重新获取定位辅助数据后,获取定位辅助数据,由终端触发获取新的定位辅助数据,避免因持续监听广播来更新定位辅助数据造成的资源浪费,节约电量及存储资源。

如图2所示,为本发明实施例提供的一种播发信息的系统结构图,该系统包括:定位服务器20,基站21及终端22,其中:
所述定位服务器20,用于确定定位辅助数据的有效区域和定位辅助数据的有效时间;通过基站广播所述有效区域和所述有效时间,以使终端根据所述有效区域和所述有效时间在确定需要重新获取定位辅助数据后,重新获取定位辅助数据。
所述基站21,用于接收定位服务器发送的定位辅助数据的有效区域和定位辅助数据的有效时间;将所述有效区域和所述有效时间广播给终端,以使终端根据所述有效区域和所述有效时间在确定需要重新获取定位辅助数据后,重新获取定位辅助数据。
所述终端22,用于接收基站广播的定位辅助数据的有效区域和定位辅助数据的有效时间;根据所述有效区域和所述有效时间在确定需要重新获取定位辅助数据后,重新获取定位辅助数据。
上述方案,定位服务器将定位辅助数据的有效区域和定位辅助数据的有效时间通过基站广播给终端,终端在接收到基站广播的定位辅助数据的有效区域和定位辅助数据的有效时间后,根据定位辅助数据的有效区域和定位辅助数据的有效时间在确定需要重新获取定位辅助数据后,重新获取定位辅助数据;由终端触发重新获取定位辅助数据,并不是持续监听广播以获取新的定位辅助数据,节约电量;同时每次获取新的定位辅助数据是终端确定需要获取后执行的,因此每次获取到的定位辅助数据不同,避免了终端的额外消耗。
在实际应用中,定位服务器确定要广播的定位辅助数据后,确定要广播 的定位辅助数据的有效区域,及要广播的定位辅助数据的有效时间,以根据有效区域及有效时间确定定位辅助数据的有效性。
在确定要广播的定位辅助数据的有效区域,及要广播的定位辅助数据的游侠时间时,定位服务器根据要广播的定位辅助数据的数据类型及数据来源,确定定位辅助数据的有效区域和定位辅助区域的有效时间。
比如:定位辅助数据为A-GNSS的普通搜星信息,定位辅助数据的有效区域时有效时间内的相关卫星的可见区域,有效时间可设置为无限长;
定位辅助数据为A-GNSS的差分修正信息,差分数的产生周期若是1秒钟产生1次,则定位辅助数据的有效时间为1秒钟,有效区域为相关差分数可使用的区域;
定位辅助数据为观察到达时间差的定位方法(Observed Time Difference Of Arrival,OTDOA)的定位辅助数据,对于相对静态的小区部署的情况下,有效时间可设置成无限长,有效区域为当前静态的小区。
在实际应用中,定位服务器根据定位辅助数据的数据类型及数据来源,确定定位辅助数据的有效区域及定位辅助数据的有效时间时,可以根据定位服务器中预先设置的数据类型、数据来源与有效区域、有效时间的对应关系确定,在定位服务器确定定位辅助数据的数据来源及数据类型后,查找对应关系确定定位辅助数据的有效区域及定位辅助数据的有效时间;
还可以根据产生定位辅助数据的其他服务器提供的信息确定有效时间及有效区域。
在确定定位辅助数据的有效区域及定位辅助数据的有效时间后,将定位辅助数据的有效区域及定位辅助数据的有效时间发送给基站,由基站进行广播播发。
定位服务器在向基站发送定位辅助数据的有效区域及定位辅助数据的有效时间时,可以通过LPP的SIB消息和/或NRPPa消息发送;
相应的,基站接收定位服务器发送的定位辅助数据的有效区域及定位辅助数据的有效时间时,接收LPP的SIB消息和/或NRPPa消息;
基站接收到定位辅助数据的有效区域及定位辅助数据的有效时间后,将定位辅助数据的有效区域及定位辅助数据的有效时间广播时,根据接收到的定位服务器的消息,确定广播定位辅助数据的有效区域及定位辅助数据的有效时间的消息;
若基站接收定位服务器发送的LPP的SIB消息,LPP的SIB消息中携带有定位辅助数据的有效时间及定位辅助数据的有效区域,则基站将SIB消息广播给终端;或
若基站接收定位服务器发送的NRPPa消息,NAPPa消息中携带有定位辅助数据的有效时间及定位辅助数据的有效区域,则基站解析NAPPa消息,确定定位辅助数据的有效时间及定位辅助数据的有效区域,并通过RRC消息携带定位辅助数据的有效时间及定位辅助数据的有效区域,基站广播RRC消息给终端;或
若基站接收定位服务器发送的LPP的SIB消息及NRPPa消息发送的定位辅助数据的有效时间及定位辅助数据的有效区域时,LPP的SIB消息中携带的是定位辅助数据的有效时间,NRPPa消息中携带的是定位辅助数据的有效区域,则基站将SIB消息及RRC消息广播给终端,SIB消息中携带有效时间,RRC消息中携带有效区域;或
若基站接收定位服务器发送的LPP的SIB消息及NRPPa消息发送的定位辅助数据的有效时间及定位辅助数据的有效区域时,LPP的SIB消息中携带的是定位辅助数据的有效区域,NRPPa消息中携带的是定位辅助数据的有效时间,则基站将SIB消息及RRC消息广播给终端,SIB消息中携带有效区域,RRC消息中携带有效时间。
进一步,终端接收基站广播的消息,并根据广播的消息中携带的定位辅助数据的有效时间及定位辅助数据的有效区域在确定需要获取定位辅助数据后,重新获取定位辅助数据。
由于基站广播的消息不同,因此终端根据消息中携带的定位辅助数据的有效区域及定位辅助数据的有效时间确定是否需要获取定位辅助数据的方式 不同;
如下:针对上述基站广播的消息对应的四种情况对终端确定是否需要重新获取定位辅助数据进行介绍。
情况一:基站通过LPP协议携带定位辅助数据的有效区域及定位辅助数据的有效时间。
在本发明实施例中,定位服务器将定位辅助数据的有效区域、定位辅助数据的有效时间及定位辅助数据放在LPP的SIB消息内容中,发送给基站;
基站接收到定位服务器发送的携带定位辅助数据的有效区域、定位辅助数据的有效时间及定位辅助数据的LPP的SIB消息后,将LPP的SIB消息广播给终端;
终端的RRC接收到基站广播的LPP的SIB消息后,将LPP的SIB消息转发给终端中的NAS层的LPP模块;
终端中的NAS层的LPP模块保存LPP的SIB消息,并解析LPP的SIB消息,当终端中的NAS层的LPP模块解析出LPP的SIB消息中携带的定位辅助数据的有效时间后,启动定时器;并根据定位辅助数据的有效时间设定定时器时长,比如定位辅助数据的有效时间为1秒,则定时器时长可设置为1秒。
终端中的NAS层中的LPP模块同时监控定位辅助数据的时间及终端所在区域,确定时间是否超出有效时间对应的定时器时长,和/或确定终端所在区域是否超出有效区域的覆盖范围,当确定时间超出有效时间对应的定时器时长和/或区域超出有效区域的覆盖范围,将根据终端的定位业务情况确定是否需要重新获取定位辅助数据,在确定需要重新获取定位辅助数据后,重新获取定位辅助数据。
在实际应用中,终端所在区域会更换,以定位辅助数据的有效区域为小区列表,终端所在区域为小区为例;
终端中的NAS层的LPP模块在定时器启动后,监控终端所在小区是否发生变化,当终端每次更换小区时,确定更换后的小区是否在有效区域对应的 小区列表内,若更换后的小区不在小区列表内,则确定超出有效区域,终端中的NAS层的LPP模块将根据终端的定位业务情况,确定是否需要重新获取定位辅助数据,在确定需要重新获取定位辅助数据后,重新获取定位辅助数据;和/或
终端中的NAS层中的LPP模块在定时器启动后,若未超出有效区域,但是定时器超时,此时也会根据终端的定位业务情况,确定是否需要重新获取定位辅助数据,在确定需要重新获取定位辅助数据后,重新获取定位辅助数据。
在实际应用中,终端中的NAS层的LPP模块在根据终端的定位业务情况,确定是否需要重新获取定位辅助数据时,若确定定位业务停止,则终端确定不需要重新获取定位辅助数据;
若定位业务还在进行,则终端中的NAS层的LPP模块将通知终端中的RRC层重新获取定位辅助数据的广播,或向定位服务器发送请求定位辅助数据的消息。
如图3A所示,为本发明实施例提供的一种播发信息的整体方法流程图,包括如下步骤:
步骤3000,定位服务器确定要广播定位辅助数据;
步骤3001,定位服务器确定定位辅助数据的有效时间及定位辅助数据的有效区域;
步骤3002,定位服务器将确定的有效时间和有效区域通过LPP的SIB消息发送给基站;
步骤3003,基站将接收到的定位服务器发送的LPP的SIB消息广播播发给终端;
步骤3004,终端的RRC层接收基站广播的LPP的SIB消息;
步骤3005,终端的RRC层将LPP的SIB消息转发给终端的NAS层中的LPP模块;
步骤3006,终端的NAS层中的LPP模块,解析LPP的SIB消息中的有 效时间和有效区域;
步骤3007,终端的NAS层中的LPP模块根据有效时间和有效区域在确定需要重新获取定位辅助数据后,重新获取定位辅助数据。
情况二:基站通过RRC协议携带定位辅助数据的有效区域及定位辅助数据的有效时间。
在本发明实施例中,定位服务器将定位辅助数据的有效区域、定位辅助数据的有效时间及定位辅助数据通过NRPPa消息发送给基站;
基站接收到定位服务器发送的携带定位辅助数据的有效区域、定位辅助数据的有效时间及定位辅助数据的NRPPa消息后,对NRPPa消息进行解析确定有效时间、有效区域及定位辅助数据,并确定LPP定位广播消息,其中LPP定位广播消息中携带有定位辅助数据,并将LPP定位广播消息及携带有有效区域和有效时间的RRC消息中的参数通过RRC消息广播播发给基站;
终端的RRC层接收到基站广播的RRC消息后,RRC消息携带有包含有效区域及有效时间的RRC消息中的参数,LPP的定位广播消息,因此终端的RRC层对RRC消息进行解析,确定RRC消息中的参数并保存,并将LPP的定位广播消息发送给终端中的NAS层的LPP模块;
终端中的RRC层保存RRC消息中的携带有效区域及有效时间的RRC消息中的参数后,对RRC消息中的参数进行解析,确定携带的有效时间和有效区域,当解析出有效时间后启动定时器,并根据解析出的有效时间设定定时器时长,比如定位辅助数据的有效时间为1秒,则定时器时长可设置为1秒。
终端中的RRC层同时监控定位辅助数据的时间及终端所在区域,确定时间是否超出有效时间对应的定时器时长,和/或确定终端所在区域是否超出有效区域的覆盖范围:
当确定时间超出有效时间对应的定时器时长后,将定时器超时的消息上报给终端的NAS层中的LPP模块,以使终端的NAS层中的LPP模块根据终端的定位业务情况确定是否需要重新获取定位辅助数据,在确定需要重新获取定位辅助数据后,重新获取定位辅助数据;和/或
当确定终端所在区域超出有效区域的覆盖范围后,将超出有效区域覆盖范围的消息上报给终端的NAS层的LPP模块,以使终端的NAS层中的LPP模块根据终端的定位业务情况确定是否需要重新获取定位辅助数据,在确定需要重新获取定位辅助数据后,重新获取定位辅助数据。
在实际应用中,终端所在区域会更换,以定位辅助数据的有效区域为小区列表,终端所在区域为小区为例;
在定时器启动后,终端中的RRC层监控终端所在小区是否发生变化,当终端每次更换小区时,确定更换后的小区是否在有效区域对应的小区列表内,若更换后的小区不在小区列表内,则确定超出有效区域,向终端的NAS层的LPP模块上报超出有效区域的消息;和/或
在定时器启动后,终端中的RRC层确定终端所在区域未超出有效区域,但定时器超时,向终端的NAS层的LPP模块上报定时器超时的消息。
在实际应用中,终端中的NAS层的LPP模块在根据终端的定位业务情况,确定是否需要重新获取定位辅助数据时,若确定定位业务停止,则终端确定不需要重新获取定位辅助数据;
若定位业务还在进行,则终端中的NAS层的LPP模块将通知终端中的RRC层重新获取定位辅助数据的广播,或向定位服务器发送请求定位辅助数据的消息。
如图3B所示,为本发明实施提供的另一种播发信息的整体方法流程图,包括如下步骤:
步骤3010,定位服务器确定要广播定位辅助数据;
步骤3011,定位服务器确定定位辅助数据的有效时间及定位辅助数据的有效区域;
步骤3012,定位服务器将确定的有效时间和有效区域通过NRPPa消息发送给基站;
步骤3013,基站接收定位服务器发送的NRPPa消息,确定NRPPa消息中的有效时间和有效区域;
步骤3014,基站将有效时间和有效区域携带在RRC消息的参数中,并向终端广播RRC消息;
步骤3015,终端的RRC层接收基站广播的RRC消息;
步骤3016,终端的RRC层保存RRC消息中携带有效时间和有效区域的参数;
步骤3017,终端的RRC层解析RRC消息中的有效时间和有效区域;
步骤3018,终端的RRC层在确定超出有效区域和/或超时后,向终端的NAS层的LPP模块上报超出有效区域和/或超时的消息;
步骤3019,终端的NAS层的LPP模块接收到RRC上报的消息后,确定需要重新获取定位辅助数据后,重新获取定位辅助数据。
情况三:基站通过RRC协议携带定位辅助数据的有效区域,及基站通过LPP协议携带定位辅助数据的有效时间。
在本发明实施例中,定位服务器将定位辅助数据的有效区域通过NRPPa消息发送给基站,及定位辅助数据的有效时间及定位辅助数据放在LPP的SIB消息内容中发送给基站。
基站接收到定位服务器发送的携带定位辅助数据的有效区域的NRPPa消息,及携带定位辅助数据的有效时间及定位辅助数据的LPP的SIB消息;
进一步基站将NRPPa消息中的定位辅助数据的有效区域通过RRC消息中的参数广播给终端,即在RRC消息中的参数携带定位辅助数据的有效区域,及将携带定位辅助数据的有效时间及定位辅助数据的LPP的SIB消息发送给终端。
终端的RRC接收到基站广播的LPP的SIB消息后,将LPP的SIB消息转发给终端中的NAS层的LPP模块,及终端的RRC接收到RRC消息后,保留RRC消息中的参数;
因此在终端的RRC层判断终端所在区域是否为有效区域,在终端的NAS层中的LPP模块确定是否超时;
若在终端的RRC层确定终端超出有效区域后,将终端超出有效区域的信 息上报给终端的NAS层中的LPP模块,由终端的NAS层中的LPP模块根据终端的定位业务情况,确定是否需要重新获取定位辅助数据,在确定需要重新获取定位辅助数据后,重新获取定位辅助数据;
若在终端的NAS层中的LPP模块确定定时器超时后,终端的NAS层中的LPP模块根据终端的定位业务情况,确定是否需要重新获取定位辅助数据,在确定需要重新获取定位辅助数据后,重新获取定位辅助数据。
在实际应用中,终端中的NAS层的LPP模块在根据终端的定位业务情况,确定是否需要重新获取定位辅助数据时,若确定定位业务停止,则终端确定不需要重新获取定位辅助数据;
若定位业务还在进行,则终端中的NAS层的LPP模块将通知终端中的RRC层重新获取定位辅助数据的广播,或向定位服务器发送请求定位辅助数据的消息。
情况四:基站通过RRC协议携带定位辅助数据的有效时间,及基站通过LPP协议携带定位辅助数据的有效区域。
在本发明实施例中,定位服务器将定位辅助数据的有效时间通过NRPPa消息发送给基站,及定位辅助数据的有效区域及定位辅助数据放在LPP的SIB消息内容中发送给基站。
基站接收到定位服务器发送的携带定位辅助数据的有效时间的NRPPa消息,及携带定位辅助数据的有效区域及定位辅助数据的LPP的SIB消息;
进一步基站将NRPPa消息中的定位辅助数据的有效时间通过RRC消息中的参数广播给终端,即在RRC消息中的参数携带定位辅助数据的有效时间,及将携带定位辅助数据的有效区域及定位辅助数据的LPP的SIB消息发送给终端。
终端的RRC接收到基站广播的LPP的SIB消息后,将LPP的SIB消息转发给终端中的NAS层的LPP模块,及终端的RRC接收到RRC消息后,保留RRC消息中的参数;
因此在终端的RRC层判断是否超时,在终端的NAS层中的LPP模块确 定终端所在区域是否为有效区域;
若在终端的RRC层确定超时后,将超时的信息上报给终端的NAS层中的LPP模块,由终端的NAS层中的LPP模块根据终端的定位业务情况,确定是否需要重新获取定位辅助数据,在确定需要重新获取定位辅助数据后,重新获取定位辅助数据;
若在终端的NAS层中的LPP模块确定终端所在区域不在有效区域覆盖范围内,终端的NAS层中的LPP模块根据终端的定位业务情况,确定是否需要重新获取定位辅助数据,在确定需要重新获取定位辅助数据后,重新获取定位辅助数据。
在实际应用中,终端中的NAS层的LPP模块在根据终端的定位业务情况,确定是否需要重新获取定位辅助数据时,若确定定位业务停止,则终端确定不需要重新获取定位辅助数据;
若定位业务还在进行,则终端中的NAS层的LPP模块将通知终端中的RRC层重新获取定位辅助数据的广播,或向定位服务器发送请求定位辅助数据的消息。
