相关申请的交叉引用
本申请主张在2017年8月3日在中国提交的中国专利申请号No.201710656723.0的优先权,其全部内容通过引用包含于此。
技术领域
本公开实施例涉及通信技术领域,尤其涉及一种终端接入核心网的方法、基站及终端。
背景技术
在长期演进(Long Term Evolution,简称LTE)系统从4G过渡到5G的过程中,存在一种场景,就是增强的LTE基站(后称eLTE基站),既可以连接到4G的核心网,又可以连接到5G的核心网。
其中,eLTE的网络架构图可能有如下三种:
第一种:只连接到演进的分组核心网(Evolved Packet Core,简称EPC),即4G核心网,该核心网的架构与36.300中的架构一致。
其中,演进的统一陆地无线接入网络(E-UTRAN)的网络架构如图1所示:E-UTRAN由基站(Evolved Node B,简称eNB)组成。eNB完成接入网功能,与用户终端(User Equipment,简称UE)通过空口通信。UE与eNB之间既存在控制面连接又存在用户面连接。对于每一个附着到网络的UE,由一个移动管理实体(Mobility Management Entity,简称MME)为其提供服务,MME与eNB之间采用S1-MME接口相连。S1-MME接口为UE提供控制面服务,包括移动性管理和承载管理功能。
服务网关(Serving GateWay,简称S-GW)与eNB之间采用S1-U接口相连,对于每一个附着到网络的UE,有一个S-GW为其提供服务。S1-U接口为UE提供用户面服务,UE的用户面数据通过S1-U承载在S-GW和eNB之间传输。
第二种:如图2所示,为双核心网的网络架构,可以同时连接到EPC和 5GC(5G核心网)。
第三种:如图3所示,为只连接到5GC的网络架构。
然而,对于图2所示的网络架构中,由于eLTE基站连接到两个核心网上,在终端接入网络的时候,就需要对核心网进行选择。但是,目前还没有明确的方案解决该技术问题。

具体地,本公开的实施例提供了一种终端接入核心网的方法、基站及终端,解决了相关技术中在双核心网的网络架构中,终端接入网络时,无法选择所接入的核心网的技术问题。
第一实施例
如图4所示,本公开的实施例提供了一种终端接入核心网的方法,具体包括以下步骤:
步骤41:向终端发送基站的公共陆地移动网络PLMN指示信息。
具体的,所述PLMN指示信息中包括连接第一类型核心网的PLMN信息以及连接第二类型核心网的PLMN信息。其中,连接第一类型核心网的PLMN与连接第二类型核心网的PLMN可存在交集,即存在既连接第一类型核心网又连接第二类型核心网的PLMN。此外,第一类型核心网具体可为4G核心网,第二类型核心网具体可为5G核心网。
其中,PLMN指示信息具体可通过广播的形式发送给终端。当然,对于PLMN指示信息的具体发送形式并不局限于此。
此外,对于连接第一类型核心网的PLMN信息以及连接第二类型核心网的PLMN信息的具体发送形式,可按照如下两种方式进行:
方式一:可选地,步骤41包括:
将第一PLMN列表和第二PLMN列表发送给终端,其中,所述第一PLMN列表中包括连接第一类型核心网的PLMN信息,所述第二PLMN列表中包括连接第二类型核心网的PLMN信息。
其中,第一PLMN列表具体可为现有的PLMN列表,而第二PLMN列表为新增加的PLMN列表。即可使用现有的PLMN列表携带连接第一类型核 心网的PLMN的信息,增加新的PLMN列表来提供连接到第二核心网的PLMN的信息。
具体地,举例而言,假设基站是多个运营商共享的,不同运营商所连接的核心网不同。比如PLMN 1只连接4G核心网,PLMN 2、PLMN 3可以连接4G和5G这两个核心网,PLMN 4只连接5G核心网。那么在第一PLMN列表中提供PLMN 1、PLMN 2、PLMN 3的信息,在第二PLMN列表中提供PLMN 2、PLMN 3、PLMN 4的信息。
方式二:可选地,步骤41包括:
将第三PLMN列表、所述第三PLMN列表的第一指示信息以及第四PLMN列表发送给终端;其中,所述第三PLMN列表中包括只连接第一类型核心网的PLMN信息以及连接第一类型核心网和第二类型核心网的PLMN信息;所述第一指示信息用于指示所述第三PLMN列表中的PLMN是否连接第二类型核心网;所述第四PLMN列表中包括只连接第二类型核心网的PLMN信息。
其中,第三PLMN列表具体可为现有的PLMN列表,第四PLMN列表为新增加的PLMN列表。即可使用现有的PLMN列表携带连接第一类型核心网的PLMN的信息以及连接第一类型核心网和第二类型核心网这两个核心网的PLMN的信息,并增加单独的比特流(bitmap)来指示对应到该列表的每个PLMN是否与第二类型核心网连接,增加单独的列表携带只连接第二类型核心网的PLMN的信息。
具体地,举例而言,假设基站是多个运营商共享的,不同运营商所连接的核心网不同。比如PLMN 1只连接4G核心网,PLMN 2、PLMN 3可以连接4G和5G这两个核心网,PLMN 4只连接5G核心网。那么在第三PLMN列表中提供PLMN 1、PLMN 2、PLMN 3的信息,在bitmap中提供011,其中0表示不支持连接到5G核心网,1表示也支持连接到5G核心网。第一个比特对应第三PLMN列表中的第一个PLMN,第二个比特对应第三PLMN列表中的第二个PLMN,以此类推。在第四PLMN列表中提供仅连接到5G核心网的PLMN的信息,即PLMN 4的信息。
此外,由于连接第一类型核心网的PLMN与连接第二类型核心网的 PLMN可存在交集,即存在既连接第一类型核心网又连接第二类型核心网的PLMN。则,对于支持双核心网的PLMN,还可在PLMN指示信息中还可以额外提供特定信息用来指示该PLMN是优先连接第二类型核心网,还是优先连接第一类型核心网。
即进一步地,所述PLMN指示信息中还包括:优先核心网指示信息,用于指示连接第一类型核心网和第二类型核心网的PLMN的优先核心网,所述优先核心网为第一类型核心网或第二类型核心网。即通过“优先核心网指示信息”来指示支持双核心网的PLMN是优先连接第二类型核心网,还是优先连接第一类型核心网,从而便于终端根据所要接入的核心网选择与自身匹配的PLMN。
具体地,举例而言,若PLMN 2、PLMN 3可以连接4G和5G这两个核心网,则额外给出2比特的信息10,1表示5G核心网为高优先级,0表示4G核心网为高优先级。对于10,则表示PLMN 2的5G核心网为高优先级,PLMN 3的4G核心网为高优先级。
进一步地,所述PLMN指示信息中还包括:每个PLMN下的跟踪区域码和/或每个PLMN下的小区标识。即基站在广播连接第一类型核心网的PLMN信息以及连接第二类型核心网的PLMN信息的同时,还可以提供每个PLMN下的跟踪区域码(Tracking Area Code,简称TAC)以及该小区的标识。即不同的PLMN,这些信息可以不同,也可以相同,取决于运营商的规划和部署。其中,将每个PLMN下的TAC广播给终端,可以使得终端只要在TAC范围内移动,就不必与网络侧交互,且网络可直接在TAC范围内寻呼终端,有效性更高。而且针对同一个小区,为每个PLMN给分配不同的小区标识,则可以使得各个运营商之间无需协商就可以互不干扰。即本公开的实施例,充分考虑了网络共享的场景,使得不同的运营商可以灵活部署和使用同一eLTE基站,而不需要跟其他运营商紧耦合部署。
步骤42:接收所述终端根据所述PLMN指示信息所选择的与所述终端相匹配的目标PLMN的信息,并根据所述目标PLMN的信息确定所述终端所要接入的目标核心网。
其中,通过步骤41将基站的PLMN指示信息发送给终端后,终端会根 据接收到的PLMN指示信息进行PLMN选择,从而选择出与自身相匹配(即与自身安装的SIM卡相匹配)的PLMN。
具体地,终端接收到基站的PLMN指示信息后,将其中终端可识别的PLMN相关的所有信息都转发给非接入层(Non-access stratum,简称NAS)。其中,若终端为传统4G终端,则该终端只能识别上面提及的第一PLMN列表或第三PLMN列表,并在识别到的PLMN列表中选择合适的PLMN;若终端为支持增强的eLTE终端,则可识别上面提及的第一PLMN列表、第二PLMN列表、支持双核心网的PLMN的优先核心网指示信息,或者第三PLMN列表、第三PLMN列表的指示信息、第四PLMN列表、支持双核心网的PLMN的优先核心网指示信息。
当NAS选定了目标PLMN后,会通知给接入层(access stratum,简称AS),AS则在该PLMN下选择合适的小区进行驻留,从而在该终端发起接入,连接到网络时,把所选择的目标PLMN的信息发送给基站。
其中,若终端所选择的目标PLMN只支持一种核心网,则基站直接根据目标PLMN就可以确定出终端所要接入的核心网。
另外,若终端所选择的目标PLMN支持双核心网,则终端还需指示是否需要接入第二类型核心网,即终端在将目标PLMN的信息发送给基站的同时,还需告知基站其需要接入该目标PLMN所支持的双核心网中的哪一个核心网。
即当所述目标PLMN连接第一类型核心网和第二类型核心网时,所述目标PLMN的信息包括用于指示所述目标PLMN连接第一类型核心网和第二类型核心网的第二指示信息;
所述接收所述终端根据所述PLMN指示信息所选择的与所述终端相匹配的目标PLMN的信息,并根据所述目标PLMN的信息确定所述终端所要接入的目标核心网的步骤,包括:
接收所述终端根据所述PLMN指示信息选择的与所述终端相匹配的目标PLMN的信息,以及用于指示所述终端是否需要接入第二类型核心网的第三指示信息;以及
根据所述第三指示信息以及所述目标PLMN的信息中包括的所述第二指示信息,确定所述终端所要接入的目标核心网。
因此,当终端所选择的目标PLMN支持双核心网时,基站需要根据接收到的“用于指示所述目标PLMN连接第一类型核心网和第二类型核心网的第二指示信息”以及“用于指示所述终端是否需要接入第二类型核心网的第三指示信息”,确定出终端所要接入的目标核心网是第一类型核心网,还是第二类型核心网。具体地,若第三指示信息指示终端需要接入第二类型核心网时,则目标核心网为第二类型核心网;若第三指示信息指示终端不需要接入第二类型核心网时,由第二指示信息得知目标PLMN还支持第一类型核心网,则目标核心网为第一类型核心网。
步骤43:与所述目标核心网和所述终端进行交互,使得所述终端通过所述目标PLMN接入所述目标核心网。
当通过步骤42确定出终端所要接入的目标核心网后,则基站通过与目标核心网和终端的交互,使得终端通过目标PLMN接入该目标核心网。
此外,可选地,所述方法还包括:
接收所述终端上报的所述终端所支持的优选PLMN的信息以及优选核心网,所述优选核心网为第一类型核心网或第二类型核心网;以及
当所述终端移出所述基站时,所述基站选择支持所述优选PLMN和所述优选核心网的目标基站,并通知所述目标基站为所述终端进行资源配置,以使得所述终端切换到所述目标基站上。
即终端可以在接入网络时或者之后,上报自己喜欢的网络,即优选PLMN的信息以及优选核心网,比如用户设置了优选的网络是某个/某些PLMN的第二类型核心网。当终端即将移动出当前基站,基站为其准备要切换的目标基站时,基站可以参考终端上报的用户个人喜好的网络信息为其选择合适的目标基站和目标网络。如果目标基站支持该终端喜欢的目标网络,则为其准备相应的资源和配置,其中包括确认目标核心网是否接纳该用户等。目标基站在选择了确定的目标网络和目标小区后,将相关切换命令反馈给原基站,以使得终端可以切换到目标基站上。
综上所述,根据本公开的实施例,通过基站将连接第一类型核心网的PLMN信息以及连接第二类型核心网的PLMN信息发送给终端,使得终端从这些PLMN中选出与自身相匹配的目标PLMN,进而根据终端所选出的目标 PLMN确定出终端所接入的核心网。因此,本公开的实施例解决了相关技术中在双核心网的网络架构中,终端接入网络时,无法选择所接入的核心网的技术问题。
由此可知,本公开的实施例,针对eLTE基站连接到两个核心网的情景,给出了解决方案,以使得该基站既可以服务于原来的4G终端,又可以服务于支持5G NAS的增强型终端,从而保证了演进的过渡网络可以兼容多种制式的终端,使其顺利地从该网络获得服务。此外,本公开的实施例,也充分考虑了网络共享的场景,使得不同的运营商可以灵活部署和使用同一eLTE基站,而不需要跟其他运营商紧耦合部署。
第二实施例
如图5所示,本公开的实施例提供了一种终端接入核心网的方法,具体包括以下步骤:
步骤51:接收基站发送的所述基站的PLMN指示信息。
所述PLMN指示信息中包括连接第一类型核心网的PLMN信息以及连接第二类型核心网的PLMN信息。其中,连接第一类型核心网的PLMN与连接第二类型核心网的PLMN可存在交集,即存在既连接第一类型核心网又连接第二类型核心网的PLMN。此外,第一类型核心网具体可为4G核心网,第二类型核心网具体可为5G核心网。
此外,对于连接第一类型核心网的PLMN信息以及连接第二类型核心网的PLMN信息的具体接收形式,可按照如下两种方式进行:
方式一:可选地,步骤51包括:接收基站发送的第一PLMN列表和第二PLMN列表,其中,所述第一PLMN列表中包括连接第一类型核心网的PLMN信息,所述第二PLMN列表中包括连接第二类型核心网的PLMN信息。
其中,第一PLMN列表具体可为现有的PLMN列表,而第二PLMN列表为新增加的PLMN列表。即可使用现有的PLMN列表携带连接第一类型核心网的PLMN的信息,增加新的PLMN列表来提供连接到第二核心网的PLMN的信息。
具体地,举例而言,假设基站是多个运营商共享的,不同运营商所连接的核心网不同。比如PLMN 1只连接4G核心网,PLMN 2、PLMN 3可以连 接4G和5G这两个核心网,PLMN 4只连接5G核心网。那么在第一PLMN列表中提供PLMN 1、PLMN 2、PLMN 3的信息,在第二PLMN列表中提供PLMN 2、PLMN 3、PLMN 4的信息。
方式二:可选地,步骤51包括:
接收基站发送的第三PLMN列表、所述第三PLMN列表的第一指示信息以及第四PLMN列表;其中,所述第三PLMN列表中包括只连接第一类型核心网的PLMN信息以及连接第一类型核心网和第二类型核心网的PLMN信息;所述第一指示信息用于指示所述第三PLMN列表中的PLMN是否连接第二类型核心网;所述第四PLMN列表中包括只连接第二类型核心网的PLMN信息。
其中,第三PLMN列表具体可为现有的PLMN列表,第四PLMN列表为新增加的PLMN列表。即可使用现有的PLMN列表携带连接第一类型核心网的PLMN的信息以及连接第一类型核心网和第二类型核心网这两个核心网的PLMN的信息,并增加单独的bitmap来指示对应到该列表的每个PLMN是否与第二类型核心网连接,增加单独的列表携带只连接第二类型核心网的PLMN的信息。
具体地,举例而言,假设基站是多个运营商共享的,不同运营商所连接的核心网不同。比如PLMN 1只连接4G核心网,PLMN 2、PLMN 3可以连接4G和5G这两个核心网,PLMN 4只连接5G核心网。那么在第三PLMN列表中提供PLMN 1、PLMN 2、PLMN 3的信息,在bitmap中提供011,其中0表示不支持连接到5G核心网,1表示也支持连接到5G核心网。第一个比特对应第三PLMN列表中的第一个PLMN,第二个比特对应第三PLMN列表中的第二个PLMN,以此类推。在第四PLMN列表中提供仅连接到5G核心网的PLMN的信息,即PLMN 4的信息。
此外,由于连接第一类型核心网的PLMN与连接第二类型核心网的PLMN可存在交集,即存在既连接第一类型核心网又连接第二类型核心网的PLMN。则,对于支持双核心网的PLMN,还可在PLMN指示信息中还可以额外提供特定信息用来指示该PLMN是优先连接第二类型核心网,还是优先连接第一类型核心网。
即进一步地,所述PLMN指示信息中还包括:优先核心网指示信息,用于指示连接第一类型核心网和第二类型核心网的PLMN的优先核心网,所述优先核心网为第一类型核心网或第二类型核心网。即通过“优先核心网指示信息”来指示支持双核心网的PLMN是优先连接第二类型核心网,还是优先连接第一类型核心网,从而便于终端根据所要接入的核心网选择与自身匹配的PLMN。
具体地,举例而言,若PLMN 2、PLMN 3可以连接4G和5G这两个核心网,则额外给出2比特的信息10,1表示5G核心网为高优先级,0表示4G核心网为高优先级。对于10,则表示PLMN 2的5G核心网为高优先级,PLMN 3的4G核心网为高优先级。
进一步地,所述PLMN指示信息中还包括:每个PLMN下的跟踪区域码和/或每个PLMN下的小区标识。即基站在广播连接第一类型核心网的PLMN信息以及连接第二类型核心网的PLMN信息的同时,还可以提供每个PLMN下的TAC以及该小区的标识。即不同的PLMN,这些信息可以不同,也可以相同,取决于运营商的规划和部署。其中,将每个PLMN下的TAC广播给终端,可以使得终端只要在TAC范围内移动,就不必与网络侧交互,且网络可直接在TAC范围内寻呼终端,有效性更高。而且针对同一个小区,为每个PLMN给分配不同的小区标识,则可以使得各个运营商之间无需协商就可以互不干扰。即本公开的实施例,充分考虑了网络共享的场景,使得不同的运营商可以灵活部署和使用同一eLTE基站,而不需要跟其他运营商紧耦合部署。
步骤52:根据所述PLMN指示信息,选择与终端相匹配的目标PLMN。
其中,通过步骤51接收到基站的PLMN指示信息后,终端会根据接收到的PLMN指示信息进行PLMN选择,从而选择出与自身相匹配(即与自身安装的SIM卡相匹配)的PLMN。
具体地,终端接收到基站的PLMN指示信息后,将其中终端可识别的PLMN相关的所有信息都转发给NAS。其中,若终端为传统4G终端,则该终端只能识别上面提及的第一PLMN列表或第三PLMN列表,并在识别到的PLMN列表中选择合适的PLMN;若终端为支持增强的eLTE终端,则可识别上面提及的第一PLMN列表、第二PLMN列表、支持双核心网的PLMN 的优先核心网指示信息,或者第三PLMN列表、第三PLMN列表的指示信息、第四PLMN列表、支持双核心网的PLMN的优先核心网指示信息。
当NAS选定了目标PLMN后,会通知给AS,AS则在该PLMN下选择合适的小区进行驻留,从而在该终端发起接入,连接到网络时,把所选择的目标PLMN的信息发送给基站。
步骤53:将所述目标PLMN的信息发送给所述基站。
其中,所述目标PLMN的信息可作为无线资源控制(Radio Resource Control,简称RRC)连接建立请求消息或者RRC连接建立完成消息的携带信息发送给所述基站。
另外,若终端所选择的目标PLMN只支持一种核心网,则基站直接根据目标PLMN就可以确定出基站所要接入的核心网。
若终端所选择的目标PLMN支持双核心网,则终端还需指示是否需要接入第二类型核心网,即终端在将目标PLMN的信息发送给基站的同时,还需告知基站其需要接入该目标PLMN所支持的双核心网中的哪一个核心网。
即可选地,当所述目标PLMN连接第一类型核心网和第二类型核心网时,所述目标PLMN的信息包括用于指示所述目标PLMN连接第一类型核心网和第二类型核心网的第二指示信息;步骤53包括:
将包括所述第二指示信息的所述目标PLMN的信息以及用于指示所述终端是否需要接入第二类型核心网的第三指示信息发送给所述基站。
因此,当终端所选择的目标PLMN支持双核心网时,基站需要根据接收到的“用于指示所述目标PLMN连接第一类型核心网和第二类型核心网的第二指示信息”以及“用于指示所述终端是否需要接入第二类型核心网的第三指示信息”,确定出终端所要接入的目标核心网是第一类型核心网,还是第二类型核心网。具体地,若第三指示信息指示终端需要接入第二类型核心网时,则目标核心网为第二类型核心网;若第三指示信息指示终端不需要接入第二类型核心网时,由第二指示信息得知目标PLMN还支持第一类型核心网,则目标核心网为第一类型核心网。
可选地,所述方法还包括:
向所述基站上报所述终端所支持的优选PLMN的信息以及优选核心网, 以使得所述终端移出所述基站时,所述基站为所述终端选择支持所述优选PLMN和所述优选核心网的目标基站,并通知所述目标基站为所述终端进行资源配置,使得所述终端切换到所述目标基站上;其中,所述优选核心网为第一类型核心网或第二类型核心网。
即终端可以在接入网络时或者之后,上报自己喜欢的网络,即优选PLMN的信息以及优选核心网,比如用户设置了优选的网络是某个/某些PLMN的第二类型核心网。当终端即将移动出当前基站,基站为其准备要切换的目标基站时,基站可以参考终端上报的用户个人喜好的网络信息为其选择合适的目标基站和目标网络。如果目标基站支持该终端喜欢的目标网络,则为其准备相应的资源和配置,其中包括确认目标核心网是否接纳该用户等。目标基站在选择了确定的目标网络和目标小区后,将相关切换命令反馈给原基站,以使得终端可以切换到目标基站上。
综上所述,本公开的实施例,通过基站将连接第一类型核心网的PLMN信息以及连接第二类型核心网的PLMN信息发送给终端,使得终端从这些PLMN中选出与自身相匹配的目标PLMN,进而根据终端所选出的目标PLMN确定出终端所接入的核心网。因此,本公开的实施例解决了相关技术中在双核心网的网络架构中,终端接入网络时,无法选择所接入的核心网的技术问题。
由此可知,本公开的实施例,针对eLTE基站连接到两个核心网的情景,给出了解决方案,以使得该基站既可以服务于原来的4G终端,又可以服务于支持5G NAS的增强型终端,从而保证了演进的过渡网络可以兼容多种制式的终端,使其顺利地从该网络获得服务。此外,本公开的实施例,也充分考虑了网络共享的场景,使得不同的运营商可以灵活部署和使用同一eLTE基站,而不需要跟其他运营商紧耦合部署。
第三实施例
由上述第一实施例和第二实施例可知,本公开实施例的终端接入核心网的方法的在终端与基站之间可按照图6执行:
步骤61:基站广播发送PLMN指示信息,其中,PLMN指示信息中包括连接第一类型核心网的PLMN信息和连接第二类型核心网的PLMN信息,第 一类型核心网为4G核心网,第二类型核心网为5G核心网。
步骤62:终端NAS进行PLMN选择,并通知AS选择目标PLMN下的小区进行驻留。
步骤63:在RRC连接建立过程中将所选择的目标PLMN的信息通知给基站。
步骤64:基站根据终端提供的所选择的目标PLMN的信息建立跟相应核心网的连接。
由上述可知,本公开的实施例,通过基站将连接第一类型核心网的PLMN信息以及连接第二类型核心网的PLMN信息发送给终端,使得终端从这些PLMN中选出与自身相匹配的目标PLMN,进而根据终端所选出的目标PLMN确定出终端所接入的核心网,从而解决了相关技术中在双核心网的网络架构中,终端接入网络时,无法选择所接入的核心网的技术问题。
