为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅用以解释本发明,并不用于限定本发明。基于本发明中的实施例,本领域普通技术人员在没有做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。
需要说明的是,在本发明使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本公开。在本发明和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。
请参考图1,其示出了本发明基于的移动通信***的结构示意图。移动通信***可以是LTE***,还可以是5G***,5G***又称新空口(New Radio,NR)***,还可以是5G的更下一代移动通信技术***,或其它通信***,本实施例对此不作任何限定。
如图1所示,该移动通信***包括:网络侧设备1和终端2。
其中,网络侧设备1可以是基站(base station,BS),也可称为基站设备,是一种部署在无线接入网(Radio Access Network,RAN)用以提供无线通信功能的装置。本发明对网络侧设备1的具体实现方式不加以限定。网络侧设备1还可以包括家庭基站(Home eNB,HeNB)、中继(英文:Relay)、微微基站Pico等,还包括在未来新的通信***中提供基站功能的设备,本发明对此不作任何具体限定。
终端2是指与网络侧设备1进行数据通信的设备。终端可以经无线接入网与一个或多个核心网进行通信。终端2可以是各种形式的用户设备(user equipment,UE)、接入终端设备、用户单元、用户站、移动站、移动台(mobile station,MS)、远方站、远程终端设备、移动设备、用户终端设备)、无线通信设备、用户代理或用户装置,以上仅仅是举例,本领域技术人员能够根据 说明书公开的内容合理推断出、其他相关产品也同样适用。终端2可以通过与网络侧设备1之间的无线连接,接收网络侧设备1发送的下行数据。
需要说明的是,在图1所示的移动通信***中,可以包括多个网络侧设备1和/或多个终端2,图1中以示出一个网络侧设备1和一个终端2来举例说明,但本发明对此不作任何限定。
实施例1
基于图1所示的移动通信***,本实施例提供一种漫游网络选择方法,适用于网络侧设备1,如图2所示,该方法具体包括以下步骤:
S11,设置定时器的定时时长。
S12,向终端下发漫游引导信息,所述漫游引导信息包含PLMN列表以及所述定时器,以使所述终端在当前业务为非紧急业务时,启动所述定时器,同时输出通知信息,以通知在所述定时器到期后将进行网络切换,当未接收到响应于所述通知信息的拒绝切换指令时,待所述定时器到期后,根据所述PLMN列表进行网络选择。
应该理解,当终端远离归属地运营商(HPLMN)覆盖的地理区时,HPLMN能够找到终端当前所处区域的VPLMN(拜访地运营商),HPLMN网络通过向终端发送携带PLMN列表的漫游引导(SoR,Stearing of Roaming)信息,以引导终端接入优先级最高的VPLMN。其中,该PLMN列表中包括待选择的多个VPLMN以及与各VPLMN对应的优先级。
除了PLMN列表以外,本实施例在下发的漫游引导信息中增加了定时器。该定时器的定时时长可以通过如下步骤进行设置:
S111,获取所述终端的当前业务。例如,终端正在执行的当前业务为语音业务时,或者为XX游戏业务。
此外,还可以结合当前业务类型与终端运行当前业务类型的历史数据,来配置定时器的定时时长。例如,当终端当前业务为X游戏,终端历史运行该游戏的平均时长为C分钟,则可以将定时器的时长设置为C分钟。
S112,获取所述终端执行所述当前业务的历史时长。
例如,假设当前业务为XX游戏业务,则获取终端在预定期限(如过去三个月)内执行所述XX游戏业务的历史时长。
S113,根据所述终端执行所述当前业务的历史时长,按照预设定时策略设置所述定时时长。
例如,可以根据终端执行所述当前业务的历史时长的均值,设置所述定时时长;或者还可以根据终端执行所述当前业务的历史时长的中位数,设置所述定时时长;或者还可以根据终端执行所述当前业务的历史时长的最大值,设置所述定时时长。当然,以上仅仅是举例,本实施例并不对定时策略进行任何限制,可以根据具体需求选择任意合适的策略。
通过上述方案,使得在漫游地处于连接态的UE能够接入优先级更高的VPLMN,而又不致影响正在运行的高优先级业务,保证了用户体验。
此外,本实施例根据所述终端执行所述当前业务的历史时长来设置所述定时时长,相比于针对不同终端不同当前业务设定固定的定时时长而言,更能满足不同终端在不同业务下的个性化需求。
实施例2
基于图1所示的移动通信***,本实施例提供一种漫游网络选择方法,适用于在漫游地处于连接态的终端2,如图3所示,该方法具体包括以下步骤:
S21,接收前述网络侧设备下发的漫游引导信息,所述漫游引导信息包含PLMN列表以及定时器timer。
应该理解,当终端远离归属地运营商(HPLMN)覆盖的地理区时,HPLMN能够找到终端当前所处区域的VPLMN(拜访地运营商),HPLMN网络通过向终端发送携带PLMN列表的漫游引导(SoR,Stearing of Roaming)信息,以引导终端接入优先级最高的VPLMN。其中,该PLMN列表中包括待选择的多个VPLMN以及与各VPLMN对应的优先级。
本实施例所接收到的漫游引导信息中除了PLMN列表以外,还增加了定时器。
S22,判断当前业务是否为紧急业务,若是,则执行步骤S23,若否,则执行步骤S24。
应该理解,紧急业务是指优先级最高的业务。在本实施例中,可以根据预设判定规则来判断终端正在运行的当前业务是否为紧急业务。例如,若当前业务为紧急呼叫业务,则判定其为紧急业务;若当前业务为普通呼叫业务,则判定其为非紧急业务;若当前业务为X类型游戏业务,则判定其为紧急业务;若当前业务为Y类型游戏业务,则判定其为非紧急业务。本实施例中的判定规则可以根据用户需求进行个性化配置。
S23,当所述当前业务为紧急业务时,待所述当前业务结束后,根据所述PLMN列表进行网络选择。
例如,当所述当前业务为紧急呼叫业务时,则等待紧急呼叫挂断,当紧急呼叫挂断后,根据接收到的PLMN列表进行网络选择,即,从所述PLMN列表中选择优先级最高的VPLMN接入。从而,避免网络切换导致终端在运行紧急业务时中断,影响用户体验。
S24,当所述当前业务为非紧急业务时,启动所述定时器,并输出在所述定时器到期后将进行网络切换的通知信息。
例如,当所述当前业务被判定为非紧急业务时,启动定时器,同时在终端屏幕上显示如下通知信息“您将在x分钟/小时后切换到VPLMN X”,其中,“x分钟/小时”为定时器的定时时长,“VPLMN X”为PLMN列表中优先级最高的VPLMN。
S25,当接收到响应于所述通知信息的拒绝切换指令时,在所述当前业务结束后,根据所述PLMN列表进行网络选择。
例如,假设本实施例在“您将在x分钟/小时后切换到VPLMN X”通知信息界面上配置有“确定”和“取消”控键,若用户点击“取消”控键,即 表示其输入了拒绝切换指令,则将定时器设置为到期,并等待当前业务结束,直到所述当前业务结束后,从所述PLMN列表中选择优先级最高的VPLMN接入。从而避免网络切换导致用户认为的高优先级任务中断,影响用户体验。
S26,当未接收到响应于所述通知信息的拒绝切换指令时,待所述定时器到期后,根据所述PLMN列表进行网络选择。
例如,假设本实施例在“您将在x分钟/小时后切换到VPLMN X”通知信息界面上配置有“确定”和“取消”控键,若用户点击了“确定”控键,或者由于没注意/忽略了通知信息,既未点击“确定”,也未点击“取消”控键,则均视为未接收到响应于所述通知信息的拒绝切换指令,此时,说明当前业务并非紧急业务,也即并非用户认为的高优先级任务,则等待定时器到期后,即可从所述PLMN列表中选择优先级最高的VPLMN接入。
通过上述方案,使得在漫游地处于连接态的UE能够接入优先级更高的VPLMN,而又不致影响正在运行的高优先级业务,保证了用户体验。
实施例3
基于图1所示的移动通信***,本实施例提供一种漫游网络选择***,适用于网络侧设备1,如图4所示,该***具体包括以下步骤:
定时器设置模块11,用于设置定时器的定时时长。
漫游引导信息发送模块12,用于向终端下发漫游引导信息,所述漫游引导信息包含PLMN列表以及所述定时器,以使所述终端在当前业务为非紧急业务时,启动所述定时器,同时输出通知信息,以通知在所述定时器到期后将进行网络切换,当未接收到响应于所述通知信息的拒绝切换指令时,待所述定时器到期后,根据所述PLMN列表进行网络选择。
应该理解,当终端远离归属地运营商(HPLMN)覆盖的地理区时,HPLMN能够找到终端当前所处区域的VPLMN(拜访地运营商),HPLMN网络通过向终端发送携带PLMN列表的漫游引导(SoR,Stearing of Roaming)信息,以引导终端接入优先级最高的VPLMN。其中,该PLMN列表中包括 待选择的多个VPLMN以及与各VPLMN对应的优先级。
除了PLMN列表以外,本实施例在下发的漫游引导信息中增加了定时器,并预先采用定时器设置模块11设置定时器的定时时长,其中,定时器设置模块11具体通过如下步骤设置所述定时时长:
首先,获取所述终端的当前业务。例如,终端正在执行的当前业务为语音业务时,或者为XX游戏业务。
此外,还可以结合当前业务类型与终端运行当前业务类型的历史数据,来配置定时器的定时时长。例如,当终端当前业务为X游戏,终端历史运行该游戏的平均时长为C分钟,则可以将定时器的时长设置为C分钟。
而后,获取所述终端执行所述当前业务的历史时长。
例如,假设当前业务为XX游戏业务,则获取终端在预定期限(如过去三个月)内执行所述XX游戏业务的历史时长。
最后,根据所述终端执行所述当前业务的历史时长,按照预设定时策略设置所述定时时长。
例如,可以根据终端执行所述当前业务的历史时长的均值,设置所述定时时长;或者还可以根据终端执行所述当前业务的历史时长的中位数,设置所述定时时长;或者还可以根据终端执行所述当前业务的历史时长的最大值,设置所述定时时长。当然,以上仅仅是举例,本实施例并不对定时策略进行任何限制,可以根据具体需求选择任意合适的策略。
通过上述方案,使得在漫游地处于连接态的UE能够接入优先级更高的VPLMN,而又不致影响正在运行的高优先级业务,保证了用户体验。
此外,本实施例根据所述终端执行所述当前业务的历史时长来设置所述定时时长,相比于针对不同终端不同当前业务设定固定的定时时长而言,更能满足不同终端在不同业务下的个性化需求。
实施例4
基于图1所示的移动通信***,本实施例提供一种漫游网络选择***, 适用于在漫游地处于连接态的终端2。如图5所示,该***具体包括:接收模块21、判断模块22、定时模块23、网络选择模块24。下面分别对各个模块进行详细描述:
接收模块21,用于接收前述网络侧设备下发的漫游引导信息,所述漫游引导信息包含PLMN列表以及定时器timer。
应该理解,当终端远离归属地运营商(HPLMN)覆盖的地理区时,HPLMN能够找到终端当前所处区域的VPLMN(拜访地运营商),HPLMN网络通过向终端发送携带PLMN列表的漫游引导(SoR,Stearing of Roaming)信息,引导终端接入优先级最高的VPLMN。其中,该PLMN列表中包括待选择的多个VPLMN以及与各VPLMN对应的优先级。
除了PLMN列表以外,本实施例接收到的漫游引导信息中还增加了定时器。
判断模块22用于判断当前业务是否为紧急业务。
应该理解,紧急业务是指优先级最高的业务。在本实施例中,根据预设判定规则来判断终端正在运行的当前业务是否为紧急业务。例如,若当前业务为紧急呼叫业务,则判定其为紧急业务;若当前业务为普通呼叫业务,则判定其为非紧急业务;若当前业务为X类型游戏业务,则判定其为紧急业务;若当前业务为Y类型游戏业务,则判定其为非紧急业务。本实施例中的判定规则可以根据用户需求进行个性化配置。
定时模块23用于当所述当前业务为非紧急业务时,启动所述定时器,并输出在所述定时器到期后将进行网络切换的通知信息。
例如,当所述当前业务被判定为非紧急业务时,启动定时器,同时在终端屏幕上显示如下通知信息“您将在x分钟/小时后切换到VPLMN X”,其中,“x分钟/小时”为定时器的定时时长,“VPLMN X”为PLMN列表中优先级最高的VPLMN。
网络选择模块24用于当接收到响应于所述通知信息的拒绝切换指令时, 在所述当前业务结束后,根据所述PLMN列表进行网络选择。
例如,假设本实施例在“您将在x分钟/小时后切换到VPLMN X”通知信息界面上配置有“确定”和“取消”控键,若用户点击“取消”控键,表示其输入了拒绝切换指令,则将定时器设置为到期,并等待当前业务结束,直到所述当前业务结束后,从所述PLMN列表中选择优先级最高的VPLMN接入。从而避免网络切换导致用户认为的高优先级任务中断,影响用户体验。
网络选择模块24还用于当未接收到响应于所述通知信息的拒绝切换指令时,待所述定时器到期后,根据所述PLMN列表进行网络选择。
例如,假设本实施例在“您将在x分钟/小时后切换到VPLMN X”通知信息界面上配置有“确定”和“取消”控键,若用户点击了“确定”控键,或者由于没注意/忽略了通知信息,既未点击“确定”,也未点击“取消”控键,则均视为未接收到响应于所述通知信息的拒绝切换指令,此时,说明当前业务并非紧急业务也并非用户认为的高优先级任务,则等待定时器到期后,即可从所述PLMN列表中选择优先级最高的VPLMN接入。
网络选择模块24还用于当所述当前业务为紧急业务时,待所述当前业务结束后,根据所述PLMN列表进行网络选择。
例如,当所述当前业务为紧急呼叫业务时,则等待紧急呼叫挂断,当紧急呼叫挂断后,根据接收到的PLMN列表进行网络选择,即,从所述PLMN列表中选择优先级最高的VPLMN接入。从而,避免网络切换导致终端在运行紧急业务时中断,影响用户体验。
通过上述方案,使得在漫游地处于连接态的UE能够接入优先级更高的VPLMN,而又不致影响正在运行的高优先级业务,保证了用户体验。
