具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白,下面通过具体实施方式结合附图对本申请实施例作进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本申请,并不用于限定本申请。
实施例一:
在本领域一些情形中,终端接入哪个或哪些网络切片是由网络侧根据终端在各网络切片中的通信质量确定的,这样只能保证终端的通信质量,无法真正切合终端的通信需求,限制了终端侧用户的通信体验,为了解决该问题,本实施例提供一种网络切片确定方法,该网络切片确定方法由终端、服务器以及核心网相互配合实现,下面请参见图1示出的该网络切片确定方法的一种交互流程图:
S102:服务器确定终端对应的可用网络切片。
在本实施例的一些示例中,可用网络切片可以是指是终端可以立即,直接使用的网络切片,在这种情况下,当终端从服务器处获取到可用网络切片信息之后,直接就某一可用网络切片向核心网发起申请就可以享受对应网络切片提供的服务。
在本实施例的另一些示例中,可用网络切片并不仅仅包括终端可以立即,直接使用的网络切片,还可以包括终端经过一些操作之后可以使用的网络切片。例如,在本实施例的一些示例中,可用网络切片包括终端当前位置处部署的网络切片,但终端并不一定签约购买了所有的这些网络切片,所以终端当前并不一定可以直接使用某一可用网络切片。不过,在终端完成对应的签约购买操作后,就可以使用该可用网络切片了。又例如,在另一些示 例中,可用网络切片包括用户已签约购买的全部网络切片,但这些网络切片部署在不同的位置,因此,按照终端当前位置,其并不能使用其中的某些网络切片,但如果终端经过位置移动,到这些网络切片的覆盖区域内,则终端就可以使用这些网络切片了。
在本实施例的一些示例中,服务器可以基于终端当前所处的位置为其确定可用网络切片,在这种示例中,终端在向服务器发送切片查询请求时,会在切片查询请求中携带能够表征终端当前位置的信息,一些示例中,切片查询请求中携带的可以是终端当前的具体位置信息或精确定位信息,例如可以是终端的GPS定位信息。在另外一些示例中,切片查询请求中携带的是能够粗略表示终端当前位置的信息,例如,终端当前服务小区的小区标识等。
在本实施例的另一些示例中,服务器可以基于终端用户的签约信息为终端确定可用网络切片。
还有一些示例中,服务器可以结合终端当前位置以及终端用户的签约信息为其确定可用网络切片,例如服务器先基于终端当前位置筛选在该位置处部署的可用网络切片。然后,服务器还进一步结合终端用户的签约信息从可用网络切片中筛除终端用户尚未签约的网络切片,然后将保留下来的可用网络切片作为最终的可用网络切片。当然,在本实施例的另一些示例中,服务器可以先根据终端用户的签约信息进行可用网络切片的筛选,然后再结合终端的当前位置做进一步筛选。
在一些情况下,服务器在根据终端当前位置、用户签约信息中的至少一种确定可用网络切片时,还可以结合其他信息来对可用网络切片做进一步筛选,例如,在本实施例的一种示例中,服务器在为终端筛选可用网络切片的时候,可以仅筛选该终端用户在其当前所驻留网络中已签约购买的网络切片。在本实施例的另一示例中,服务器可以根据终端的当前位置结合终端侧指定的网络标识进行网络切片的筛选。例如,终端可以指定服务器筛选出位置Y处的中国移动部署的所有网络切片作为可用网络切片。
在本实施例的一些示例中,终端向服务器发送切片查询请求之前,会先按照目标制式搜索其当前所在位置处覆盖的网络,确定其当前位置处目标制式的所有网络。例如,终端可以将5G作为目标制式,然后搜索其当前位置的所有5G网络。例如,在某一位置处,同时覆盖有运营商甲部署的第一5G网络,也有运营商乙部署的第二5G网络。对于终端而言,其在搜索到同步信号后,解析同步信号中携带的系统参数,如PLMN(Public Land Mobile Network,公共陆地移动网),就可以确定是哪个运营商的网络。在这种情况下,终端可以选择使用第一5G网络还是第二5G网络,如果其选择了使用第一5G网络,则第一5G网络就是终端当前的目标网络,可以将第一5G网络的网络标识以及位置信息携带在切片查询请求中发送给服务器。
在上述示例中,服务器根据终端的请求为其确定对应的可用网络切片。在本实施例的另外一些示例中,服务器也可以在没有接收到终端侧请求的情况下,主动为终端确定对应的可用网络切片,例如,服务器可以定时或不定时地为各终端确定可用网络切片。
本实施例中的服务器包括但不限于局方服务器、第三方服务器、切片商城、AMF(Access and Mobility Management Function,接入和移动性管理功能)网元等几个中至少一个。
S104:服务器向终端发送表征终端的可用网络切片的可用网络切片信息。
服务器发送给终端的可用网络信息至少应该包含可用网络切片的切片标识。在本实施例的一些示例中,一个可用网络切片对应的可用网络切片信息中还可以进一步包括以下几 种信息中的至少一种:签约购买信息(用于表征用户是否已经签约购买了该可用网络切片)、归属运营商信息(用于表征该可用网络切片所属的运营商)、适用的业务类型、计费方式、QOS(Quality of Service,服务质量)指标信息、DNN(Data Network Name,数据网络名称)信息。
可以理解的是,可用网络切片信息并不限于上述几种,例如,在本实施例的一种示例中,可用网络切片信息中还包括是否正在使用信息(用于表征终端是否正在是否该可用网络切片)和/或已消耗流量(表征终端过去使用该可用网络切片所消耗的流量)。
在本实施例的一种示例中,用户签约购买的网络切片可能部署在不同的位置,也即服务器为终端确定出的可用网络切片可能并不是终端当前可以使用的,在这种情况下,服务器还可以将各可用网络切片的位置提供给终端,以供终端自己根据其位置从可用网络切片中选择目标网络切片。
S106:终端根据可用网络切片信息从可用网络切片中确定目标网络切片。
终端接收到服务器发送的可用网络切片信息后,可以根据可用网络切片信息从这些可用网络切片中选择出其准备接入的网络切片,选择出来的网络切片就是终端当前的目标网络切片。
在本实施例的一些示例中,终端可以不需要用户参与的情况下选择目标网络切片,例如,在本实施例的一种示例中,终端在用户启动某一APP(Application,应用程序)后选择为该APP业务选择承载业务的目标网络切片,那么终端可以从可用网络切片中选择适用业务类型与该APP业务类型匹配的网络切片作为目标网络切片。又例如,在本实施例的一种示例中,终端可以统计用户的历史切片使用习惯,然后选择符合用户使用习惯的一个可用网络切片作为目标网络切片。
在本实施例的另外一些示例中,终端可以根据用户指令选择目标网络切片,例如,用户可以通过触屏操作、语音输入等方式向终端下发切片选择指令,终端根据该切片选择指令确定目标网络切片。例如,终端还可以将可用网络切片信息呈现给用户,然后用户的选择确定目标网络切片。例如,在本实施例的一种示例当中,终端可以按照图2示出的流程来确定目标网络切片:
S202:终端显示可用网络切片信息。
终端获取到可用网络切片信息之后,对可用网络切片信息进行显示。在本实施例的一些示例中,终端可以将各可用网络切片的网络切片信息一起显示给用户,如图3所示。当可用网络切片较多,或者单个可用网络切片对应的网络切片信息较多时,终端可以将每一个可用网络切片对应的网络切片信息显示在一个独立的页面上,如图4所示。另外一些示例中,为了便于用户快速从多个可用网络切片中选择出目标网络切片,在本实施例的一些示例中,终端还可以在同一显示页面中显示多个可用网络切片在同种可用网络切片信息下的对比结果,例如在一个页面上显示各可用网络切片的QOS比较结果。又例如,在一个页面上显示过去一周内终端分别使用3个可用网络切片的总时长,如图5所示。还有一些示例中,终端可以给用户提供筛选条目供用户选择,如图6所示,当用户选择一个或多个筛选条目之后,终端可以根据这些筛选条目对可用网络切片进行筛选,然后将符合条件的可用网络切片再呈现给用户,从而简化用户的选择过程,提升人机交互的友好程度。还有一些示例中,终端可以从可用网络切片中确定出一个或多个推荐网络切片,然后在显示可用网络切片信息时,将推荐网络切片特别提示给用户。由于终端提供的推荐网络切片通常是 比较符合用户使用习惯或者是当前网络状态优良的网络切片,因此用户结合终端提供的推荐网络切片,可以较为简便地选择出目标网络切片。
在本实施例的一些示例中,终端可以基于自己过去一段时间对各类型业务的使用频次确定出常用业务类型,例如,终端基于对用户历史使用数据的统计,确定在过去一周内的常用业务为游戏业务。随后,终端可以确定游戏业务对应的网络切片作为推荐网络切片,推荐网络切片就是终端推荐用户使用的网络切片,例如可以是可用网络切片中适宜承载该游戏业务的网络切片。然后在显示可用网络切片信息时,采用推荐标识将该推荐网络切片对应的网络切片信息标识出来。例如,在图7中,终端在显示多个可用网络切片对应的网络切片信息时,在网络切片d后面备注了“推荐”的字样,以此告知用户网络切片d是推荐网络切片。当然本领域技术人员可以理解的是,推荐标识的作用就是为了将推荐网络切片的网络切片信息从各可用网络切片的网络切片信息中突出出来,因此,推荐标识并不一定是“推荐”或类似的文字,也可以是图形(例如星标图形等)、不同于其他可用网络切片信息的背景颜色等。
在本实施例的另外一些示例中,终端也可以结合自己过去一段时间使用各可用网络切片的时长来确定推荐网络切片,例如,在过去一周内,针对网络切片a、b、c、d四个网络切片,终端的使用总时长分别为1.3天、0.8天、0.3天以及1.5天,则终端可以选择使用总时长最长的网络切片d作为推荐网络切片。另外,终端还可以根据自己对各可用网络切片的使用频次或者用户主动选择各网络切片的次数等因此来确定推荐网络切片。
S204:终端接收基于显示内容下发的切片选择指令。
当用户选中某一可用网络切片作为目标网络切片时,终端会接收到切片选择指令。例如,对于触控屏终端而言,用户选中一个可用网络切片的触控操作就相当于是用户下发的切片选择指令。当然,在本实施例的其他一些示例中,切片选择指令也可以是用户向终端发出的语音指令,利用用户对这终端的语音采集设备说出“接入网络切片c”,那么该语音指令就是终端接收到的切片选择指令。
S206:终端根据切片选择指令确定目标网络切片。
终端接收到切片选择指令后,对切片选择指令进行解析,从而确定用户所选择的目标网络切片是哪一个。
S108:终端向核心网申请目标网络切片。
终端确定出目标网络切片之后,可以向核心网申请目标网络切片。终端可以向核心网发送切片申请请求,该切片申请请求中包括能够唯一标识一个网络切片的信息,例如包含有切片标识。在本实施例的一种示例中,终端可以根据目标网络切片的DNN查询URSP(UE Route Selection Policy,UE路由选择策略)规则列表,确定出目标网络切片对应的S-NSSAI(Single Network Slice Selection Assistance Information,单个网络切片选择辅助信息),然后终端将目标网络切片的S-NSSAI携带在切片申请请求中发送给核心网。
S110:核心网设备根据切片申请请求中的切片标识确定终端申请使用的目标网络切片。
核心网接收到终端发送的切片申请请求后,可以从切片申请请求中提取出切片标识,根据该切片标识确定终端所申请的目标网络切片是哪一个。例如,在一些示例中,核心网从其切片申请请求中提取出S-NSSAI,根据S-NSSAI确定出对应的目标网络切片。
S112:核心网设备与终端建立目标网络切片对应的会话。
可以理解的是,终端向核心网申请一个网络切片,实际上就是希望与网络侧之间建立 该网络切片对应的PDU会话,以便后续过程基于该PDU会话实现业务传输,所以,终端向核心网发送的切片申请请求实际上也可以被视作是PDU会话创建请求。核心网根据切片申请请求确定目标网络切片之后,可以与终端建立目标网络切片对应的PDU会话。
当然,终端还会为目标网络切片的PDU会话配置相应的网口及相关的路由。
本实施例提供的网络切片确定方法,由终端侧自己确定其接入的目标网络切片,相较于在本领域一些情形中由网络侧确定的方式,本实施例的方案向终端侧提供了更大的自主性,有利于让终端选择更适合的网络切片。而且,在本实施例中,终端还能将可用网络切片信息呈现给用户,让用户知晓终端可接入的网络切片包括哪些,并且还能让用户自己选择目标网络切片,这样用户选择的目标网络切片会更适合其业务需求,有利于提升用户体验。
另外,终端还能在向用户显示可用网络切片信息时通过推荐标识突出推荐网络切片,这样能够帮助用户选择目标网络切片,避免用户面对多个可用网络切片不知如何选择的情况发生,降低用户的选择负担,优化用户体验。
实施例二:
为了使本领域技术人员对前述网络切片确定方法的优点与细节更清楚,本实施例将结合示例对该方案做进一步阐述,请参见图8示出的交互流程图:
S802:终端获取当前的GPS定位信息,并按照目标制式搜索端网络。
在本实施例中,终端可以通过GPS定位获取到自己当前位置,不过,在本实施例的其他一些示例中,终端也可以通过基站定位获取自己的当前位置。或者终端可以不用进行精细定位,直接获取自己当前服务小区的小区标识,以服务小区的覆盖范围来粗略体现其当前所处的位置。
另一方面,终端还可以按照目标指示进行网络搜索,确定其所处位置处的网络覆盖情况。例如,在本实施例的一种示例中,终端在一个位置处同时搜索到了3个运营商提供的5G网络,终端可以获取到这三个网络的网络标识。
S804:终端向服务器发送携带GPS定位信息与目标网络的网络标识的切片查询请求。
终端可以生成切片查询请求,切片查询请求中携带有其的GPS定位信息以及其需要服务器查询的可用网络切片所属网络所属的网络标识,即目标网络的网络标识。
可以理解的是,切片查询请求中携带的网络标识可以有多个,也即,终端可以同时请求服务器查询多个目标网络在其所在位置处的网络切片。例如,在前述示例中,终端搜索到了三个运营商提供的三个不同的5G网络,那么终端可以将这三个5G网络均作为目标网络。
S806:服务器根据GPS定位信息与网络标识确定终端的可用网络切片。
服务器根据GPS定位信息可以确定出对应位置处的全部网络切片,然后进一步结合网络标识,服务器就可以筛选出终端的可用网络切片。在本实施例中,服务器在筛选可用网络切片时,不需要关注用户对网络切片的签约购买情况,因为即便是用户当前并未签约某一网络切片,但如果用户想要使用该网络切片,其也可以临时签约购买,从而获取使用该网络切片的权限。
S808:服务器将可用网络切片信息发送给终端。
服务器确定出可用网络切片之后,可以将可用网络切片对应的可用网络切片信息发送给终端。
S810:终端从可用网络切片中确定推荐网络切片。
终端接收到服务器发送的可用网络切片信息后,可以根据可用网络切片信息确定出服务器选择的可用网络切片包括哪些。另一方面,终端可以基于用户的业务使用习惯确定出推荐网络切片,在一些示例中,终端在确定推荐网络切片时,可以考虑过去一段时间用户进行各项业务的频率、次数和累计时长中的至少一个,基于这些信息确定出用户过去一段时间内的常用业务类型,然后基于常用业务类型确定出对应的推荐网络切片。在本实施例的其他一些示例中,终端也可以根据网络质量、计费方式等因素确定推荐网络切片,例如终端可以综合考虑各网络切片的QOS指标的优良程度、计费方式的实惠程度,然后选择出性价比较高的可用网络切片作为推荐网络切片。
S812:终端显示可用网络切片信息并采用推荐标识突出推荐网络切片。
在本实施例的一种示例中,终端向用户显示的可用网络切片信息包括以下几种信息中的至少一种:签约购买信息、归属运营商信息)、适用的业务类型、计费方式、QOS指标信息、DNN信息、是否正在使用信息以及已消耗流量。
另外,本实施例中,终端还会在推荐网络切片对应网络切片信息上显示推荐标识,利用推荐标识突出显示推荐网络切片对应网络切片信息。
S814:终端接收用户下发的切片选择指令。
本实施例中的终端是触控屏终端,所以,用户可以直接在终端的触控屏上进行触控操作,从而向终端指示其选择的目标网络切片。终端检测到符合条件的触控操作后,就相当于检测到了切片选择指令。终端解析用户触控操作的过程,实际上就是解析切片选择指令的过程。通过解析切片选择指令,终端可以确定用户所选择的目标网络切片。
S816:终端向核心网发送切片申请请求。
确定用户期望接入的目标网络切片后,终端可以向核心网发送切片申请请求,并在切片申请请求中携带目标网络切片的切片标识。
可以理解的是,在一些情况下,目标网络切片所属的网络与终端当前驻留的网络的运营商可能并不相同,例如,终端当前可能驻留在运营商乙的第二网络中,而目标切片网络则属于运营商丙的第三网络中,此种情况下,终端向核心网申请目标网络切片之前,还会先确保自己接入目标网络切片所属的网络。
S818:终端与网络侧建立目标网络切片对应的PDU会话并基于该PDU会话进行业务传输。
核心网接收到终端发送的切片申请请求后,可以根据切片申请请求中携带的切片标识确定出终端侧选择的目标网络切片,然后建立该目标网络切片对应的PDU会话。另一方面,终端会配置与该目标网络切片对应的网口与路由。随后,终端与网络侧可以基于建立号的PDU会话进行业务传输,从而让终端用户享受到目标网络切片所提供的通信服务。
本实施例提供的网络切片确定方法,终端在从服务器处获取到其当前所处位置处的可用网络切片后,将可用网络切片信息呈现给用户,通过推荐标识突出推荐网络切片,让用户自己选择目标网络切片,保证所选择的网络切片契合终端的业务需求,增强了可用户体验。
实施例三:
本实施例提供了一种存储介质,该存储介质包括在用于存储信息(诸如计算机可读指令、数据结构、计算机程序模块或其他数据)的任何方法或技术中实施的易失性或非易失 性、可移除或不可移除的介质。存储介质包括但不限于RAM(Random Access Memory,随机存取存储器),ROM(Read-Only Memory,只读存储器),EEPROM(Electrically Erasable Programmable read only memory,带电可擦可编程只读存储器)、闪存或其他存储器技术、CD-ROM(Compact Disc Read-Only Memory,光盘只读存储器),数字多功能盘(DVD)或其他光盘存储、磁盒、磁带、磁盘存储或其他磁存储装置、或者可以用于存储期望的信息并且可以被计算机访问的任何其他的介质。
该存储介质中可以存储有一个或多个可供一个或多个处理器读取、编译并执行的计算机程序,在本实施例中,该存储介质可以存储有第一网络切片确定程序、第二网络切片确定程序以及第三网络切片确定程序中的至少一个,其中,第一网络切片确定程序可供一个或多个处理器执行实现前述实施例介绍的任意一种网络切片确定方法中终端侧的流程。第二网络切片确定程序可供一个或多个处理器执行实现前述实施例介绍的任意一种网络切片确定方法中服务器侧的流程。第三网络切片确定程序可供一个或多个处理器执行实现前述实施例介绍的任意一种网络切片确定方法中核心网侧的流程。
本实施例还提供了一种计算机程序产品,包括计算机可读装置,该计算机可读装置上存储有如上所示的计算机程序。本实施例中该计算机可读装置可包括如上所示的计算机可读存储介质。例如,该计算机程序产品包括通信设备,如图9所示:通信设备90包括处理器91、存储器92以及用于连接处理器91与存储器92的通信总线93,其中存储器92可以为前述存储有第一终端通信控制程序与第二终端通信控制程序中至少一个的存储介质。
例如,在本实施例的一种示例中,通信设备90为终端,其处理器91可以读取第一网络切片确定程序,进行编译并执行实现前述实施例中介绍的网络切片确定方法终端侧的流程:
