目前推动MulteFire的联盟组织已成立并运营,以促进MulteFire全球技术规范的发展、推动MulteFire的未来演进并确保MulteFire设备和非授权频谱中其他设备(如WiFi)对非授权频谱资源进行公平竞争。
NH核心网(CN,Core Network)为MulteFire引入的统一规划和自组织的中立网络,接入NH网络的用户设备(UE,User Equipment)由认证、授权和计费(AAA,Authentication Authorization Accounting)服务器通过可扩
展认证协议(EAP,Extensive Authentication Protocol)进行鉴权和认证,但接入NH网络的UE不支持与3GPP网络的无线接入网(RAN,Radio Access Network)级切换。
在MulteFire的NH网络模式中,为支持多种服务提供商,包括服务提供者可以是互联网服务提供商、有限电视、移动网络运营商、企业及公共场所服务提供者等,引入了服务提供商标识(PSP-ID,Participating Service Provider Identity)。UE中可以保存多个PSP的证书,接入多个服务提供商网络。在MulteFire的NH网络模式中,NH网络与服务提供商网络的概念是相互独立的,每个MF AP属于一个NH网络,由NH网络标识(NHN-ID,Neutral Host Identity)进行标识,每个NH网络可提供给一个或多个服务提供商,即每个NH AP和NH MME可以支持多个PSP-ID,NH MME连接到多个PSP的AAA服务器,支持对不同的PSP-ID进行UE的认证、鉴权或计费。PSP-ID分为短格式和长格式两种,短格式PSP-ID可在RAN系统广播中发送给UE指示MulteFire网络支持的服务提供商。
在现有LTE技术中,当UE进入不在已注册跟踪区(TA,Tracking Area)中的位置区域,并且选择的服务网络发生变化时,UE需要发起基于IMSI的附着过程,UE在附着请求中包含国际移动用户识别码(IMSI,International Mobile Subscriber Identification Number),MME收到携带IMSI的附着请求后,必须先对UE进行鉴权再对UE进行网络注册。
在LTE系统中,LTE网络与服务提供商网络是一致的,都使用PLMN-ID标识,当UE选择的PLMN(公共陆地移动网络)发生变化时,UE发起基于IMSI的附着过程,MME收到UE的附着请求后需要对UE重新进行鉴权和注册。但是NH网络提供两种网络标识NHN-ID和PSP-ID,若UE在NHN-ID发生变化或PSP-ID发生变化时发起基于PSP的附着过程,将导致网络因为UE频繁附着带来大量的认证和注册相关的信令过程,增大网络信令负担,严重影响网络性能。
发明内容

为使本公开要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
如图1所示,在MulteFire的NH(中立主机)网络模式中,MF接入点(AP,Access Point)连接到NH核心网(CN,Core Network),NH CN类似3GPP的LTE核心网,包括NH移动性管理单元(MME,Mobility Management Element)、NH网关(GW,Gateway)和NH认证、授权和计费(AAA,Authentication Authorization Accounting)服务器。
需要说明的是,本公开的具体实施方式应用于MulteFire的NH模式中,网络运营者和服务提供者相互独立;其中,网络标识用NHN-ID表示,NHN-ID可以由RAN自由配置或者由操作维护中心统一分配,NHN-ID在RAN系统广播中发送,终端根据NHN-ID进行网络选择和小区重选。NH核心网在NH网络中为UE分配唯一的GUTI(全局唯一临时标识),即GUTI在NHN-ID下唯一分配。MME可支持多个NH网络,每个NH网络的逻辑MME由MMEC(MME代码)标识,根据NHN-ID和MMEC可唯一确定MME。服务提供商的标识用PSP-ID表示,网络通过PSP-ID确定UE的认证、鉴权或计费服务器,PSP-ID分为短格式和长格式两种,为了节省空口资源,RAN系统广播只发送MF接入点支持的短格式PSP-ID。
如图2所示,本公开的一些实施例提供一种终端接入网络的方法,包括:
步骤11,终端从第一小区移动到第二小区时,获取所述第二小区所在的第二网络的第二网络标识以及该终端在第二网络支持的服务提供商中选择的第二服务提供商的标识。
本步骤中,终端在移动过程中可能进行小区重选,终端首先在与所述第一小区所在第一网络的第一网络标识相同的小区中进行小区重选,若在与第一网络标识相同的小区中未找到合适的小区,例如小区的信号未达到要求或系统广播指示小区为禁止接入小区或阻塞小区;则终端只能选择与第一网络标识不同的小区,当终端选择到合适的小区时则进行驻留,将所驻留的小区的网络标识NHN-ID的NH网络作为服务网络。若终端在所有网络标识对应
的网络中都未找到合适小区,终端可能会改变服务提供商,即选择新的PSP-ID,并在新的PSP-ID下重新选择网络和合适小区。
当终端完成小区重选之后,终端需要获取第二小区所在的第二网络的第二网络标识、终端在第二网络支持的服务提供商中选择的第二服务提供商的标识、第一小区所在的第一网络的第一网络标识以及终端在第一网络支持的服务提供商中注册的第一服务提供商的标识。具体的,上述第一网络和第二网络可以相同也可以不同,上述第一服务提供商标识和第二服务提供商标识可以相同也可以不同。
步骤12,在所述第二网络标识与所述第一小区所在第一网络的第一网络标识不同,或者所述第二服务提供商的标识与所述终端在第一网络支持的服务提供商中注册的第一服务提供商的标识不同时,向所述第二网络发送携带有所述终端的GUTI的接入请求,以接入第二网络。
本步骤中,终端完成小区重选并获取第一网络标识、第二网络标识、第一服务提供商的标识以及第二服务提供商的标识之后,终端需要判断第二网络标识相对于第一网络标识是否发生变化,第二服务提供商的标识相对于第一服务提供商的标识是否发生变化。
对于第二网络标识发生变化或者第二服务提供商的标识发生变化的情况,本公开的第一实施例提供的方法中,终端仍然向第二网络的核心网发送接入请求,该接入请求中携带终端的GUTI,使得核心网在收到接入请求后根据其中的GUTI获取终端在NH网络中的上下文,避免核心网对终端重新进行认证和注册过程,降低了网络信令负担,提高了网络性能。
如图3、图4所示,本公开的一些实施例提供一种终端接入网络的方法,包括:
步骤21,与上述步骤11相同。
步骤22,在所述第二网络标识与第一网络标识不同,且所述第二服务提供商的标识与第一服务提供商的标识相同时,向所述第二网络发送携带有所述终端的GUTI的接入请求;或者,
步骤23,在所述第二网络标识与第一网络标识不同,且所述第二网络标识在第一网络标识的等同网络的网络标识集中,且所述第二服务提供商的标
识与第一服务提供商的标识不同,且所述第二服务提供商的标识在第一服务提供商的等同服务提供商的标识集中时,向所述第二网络发送携带有所述终端的GUTI的接入请求。
步骤22为本公开该实施例的第一种实施方式,具体为:当所述第二网络标识与第一网络标识不同时,第二服务提供商的标识与第一服务提供商的标识可以相同也可以不同;针对第二服务提供商的标识与第二服务提供商的标识相同的情况,终端向所述第二网络发送携带有所述终端的GUTI的接入请求,使得网络侧根据GUTI获得终端的上下文信息,避免对终端重新进行认证授权;而针对第二服务提供商的标识与第二服务提供商的标识不同的情况,终端向第二网络发起基于PSP的附着过程,网络侧对终端重新进行鉴权和网络注册。进一步的,当所述第二网络标识与第一网络标识不同时,若所述第二网络标识在第一网络标识的等同网络的网络标识集中,对于第二服务提供商的标识与第二服务提供商的标识相同的情况,终端向所述第二网络发送携带有所述终端的GUTI的接入请求。
需要说明的是,终端在第一服务提供商的认证、授权和计费服务器中的签约信息中包含第一服务提供商的等同服务提供商的标识集信息,表示终端在等同服务提供商中接入时,第一网络的核心网可以共享终端的上下文信息,不用对终端重新认证;和/或终端在第一服务提供商的认证、授权和计费服务器中的签约信息中包含第一网络标识的等同网络的网络标识集信息,表示终端注册到该第一服务提供商并在等同网络中接入时,核心网可以共享终端的上下文信息,不用对终端重新认证。其中,核心网为终端配置的TAI(跟踪区标识)列表可包含任意NHN-ID下的TA。
步骤23为基于上述等同服务提供商和等同网络的实施方式,即本公开的该实施例的第二种实施方式,具体为:而针对第二服务提供商的标识与第二服务提供商的标识不同的情况,还需进一步判断第二服务提供商的标识是否在第一服务提供商的等同服务提供商的标识集中,若第二服务提供商的标识不在第一服务提供商的等同服务提供商的标识集中,终端向第二网络发起基于PSP的附着过程,网络侧对终端重新进行鉴权和网络注册;而若第二服务提供商的标识在第一服务提供商的等同服务提供商的标识集中,还需判断
第二网络标识是否在第一网络标识的等同网络的网络标识集,若第二网络标识在第一网络标识的等同网络的网络标识集,向所述第二网络发送携带有所述终端的GUTI的接入请求,使得网络侧根据GUTI获得终端的上下文信息,避免对终端重新进行认证授权;若第二网络标识不在第一网络标识的等同网络的网络标识集,终端向第二网络发起基于PSP的附着过程,网络侧对终端重新进行鉴权和网络注册。
本公开的该实施例针对第二网络标识与第一网络标识不同的情况,对第二服务提供商的标识与第一服务提供商的标识的关系进行限定,从而更清楚地描述本公开的技术方案,使得本公开的方法能够避免对终端重新鉴权、认证等操作,降低网络信令负担,提高网络性能。
如图5所示,本公开的一些实施例提供一种终端接入网络的方法,包括:
步骤31,与上述步骤11相同。
步骤32,当所述第二网络标识与第一网络标识不同时,且所述第二服务提供商的标识与第一服务提供商的标识相同时,判断所述终端当前是否位于该终端保存的已注册跟踪区中的位置区域内。
步骤33,若所述终端位于所述已注册跟踪区中的位置区域内,向第二网络发送有携带有所述终端的GUTI的服务请求;
步骤34,若所述终端位于所述已注册跟踪区外的位置区域内,向第二网络发送有携带有所述终端的GUTI的位置区更新请求或者附着请求。
本公开的该实施例针对的是所述第二网络标识与第一网络标识不同时,且所述第二服务提供商的标识与第一服务提供商的标识相同的情况,即PSP-ID未变,NHN-ID变化的情况,当终端所选择的NHN-ID发生变化,终端可发起服务请求过程,从空闲状态转移到连接状态,或者终端可发起TAU(跟踪区更新)过程或基于GUTI的附着过程通知核心网终端的服务位置区域发生了改变。
如图6所示,具体的,当终端位于已注册TA的位置区域时,当有业务到达或接收到寻呼消息时,终端可发起服务请求(SR)过程,以便从空闲状态转移到连接状态;当终端进入不属于已注册TA的位置区域时,终端可发
起TAU过程或基于GUTI的附着过程通知核心网终端的服务位置区域发生了改变。其中,在本实施例中,终端的已注册TA的位置区域可包括在任意NH网络中的任意位置区域。由于终端仍然选择原先的PSP-ID,TAU请求或附着请求中携带核心网在原来的NHN-ID下为终端分配的GUTI,而不携带PSP-ID。当MME收到终端发送的TAU请求或附着请求后,根据GUTI向原先终端注册的MME请求终端的上下文,将终端当前服务的NH网络更新为新的NHN-ID(即第二网络标识)。其中,终端的上下文信息包含终端原先通过认证的PSP-ID及终端的安全上下文信息。MME成功获取终端的上下文信息后,可以更新当前服务终端的NHN-ID,不用对终端重新进行鉴权,向服务网关(SGW,service gateway)发送会话建立请求(Create Session Request)以在新的SGW中创建会话,或者向SGW发送修改承载请求(Modify Bear Request)以指示SGW当前终端注册的MME。若分组数据网关(PGW,packet gateway)向MME注册了位置报告事件,MME可在会话建立请求或修改承载请求(Modify Bear Request)消息中携带用户位置信息(User Location Information)以指示终端当前所选择的服务NHN-ID,SGW将此信息转发给PGW,以便于PCC(策略控制和计费)针对当前服务终端的NHN-ID使用特定的PCC策略。若MME未能通过NHN-ID和GUTI成功获取UE的上下文,MME向UE发送TAU拒绝命令。UE收到MME发送的TAU拒绝命令后,可发起基于PSP的附着过程,在附着请求消息中携带PSP-ID,核心网重新对该UE进行鉴权和注册。
为了更清楚的说明本公开实施例提供的终端接入网络的方法,下面对当所述第二网络标识与第一网络标识相同时,且所述第二服务提供商的标识与第一服务提供商的标识相同的情况进行描述,即PSP-ID未变,NHN-ID未变的情况。如图6所示,其PSP-ID未变,且NHN-ID未变的情况,与上述PSP-ID未变,NHN-ID变化的情况时,终端的操作方法一致,在此不进行重复描述。
需要说明的是,针对终端在第一服务提供商的认证、授权和计费服务器中的签约信息中不包含第一服务提供商的等同服务提供商的标识集信息的情况,只要所述第二服务提供商的标识与第一服务提供商的标识不同,无论所
述第二网络标识与第一网络标识是否相同,终端需要发起基于PSP的附着过程在新的PSP-ID中进行鉴权和网络注册。由于MME无需获取UE在网络中的上下文,终端在附着请求中只需携带所选择的新的PSP-ID。当MME收到终端发送的附着请求后,根据附着请求消息中的PSP-ID确定对应的AAA服务器。MME通过该AAA服务器对终端进行鉴权和认证,终端通过该PSP-ID的AAA服务器成功鉴权及认证后,MME为该终端建立默认承载和网络注册。
本公开的一些实施例中,终端在第一服务提供商的认证、授权和计费服务器中的签约信息中包含第一网络标识的等同网络的网络标识集信息,表示终端注册到该第一服务提供商并在等同网络中接入时,核心网可以共享终端的上下文信息,不用对终端重新认证。
如图7所示,本公开的一些实施例提供一种终端接入网络的方法,包括:
步骤41,与上述步骤11相同。
步骤42,当所述第二网络标识与第一网络标识不同,所述第二网络标识在第一网络标识的等同网络的网络标识集中,且所述第二服务提供商的标识与第一服务提供商的标识相同时,判断所述终端当前是否位于该终端保存的已注册跟踪区中的位置区域内;
步骤43,若所述终端位于所述已注册跟踪区中的位置区域内,向第二网络发送有携带有所述终端的GUTI的服务请求;
步骤44,若所述终端位于所述已注册跟踪区外的位置区域内,向第二网络发送有携带有所述终端的GUTI的位置区更新请求或者附着请求。
本公开的该实施例针对的是所述第二网络标识与第一网络标识不同,所述第二网络标识在第一网络标识的等同网络的网络标识集中,且所述第二服务提供商的标识与第一服务提供商的标识相同的情况,即PSP-ID未变,NHN-ID变化,但NHN-ID为等同NHN-ID时,终端可发起服务请求过程,从空闲状态转移到连接状态,或者终端可发起TAU过程或基于GUTI的附着过程通知核心网终端的服务位置区域发生了改变。
如图8所示,具体的,当终端位于已注册TA的位置区域时,当有业务
到达或接收到寻呼消息时,终端可发起服务请求SR过程,以便从空闲状态转移到连接状态;当终端进入不属于已注册TA的位置区域时,终端可发起TAU过程或基于GUTI的附着过程通知核心网终端的服务位置区域发生了改变。其中,在本实施例中,终端的已注册TA的位置区域只包含第一网络的等同网络中的位置区域。TAU请求或附着请求中携带核心网在原来的NHN-ID下为终端分配的GUTI。当MME收到终端发送的TAU请求或附着请求后,根据GUTI向原先终端注册的MME请求终端的上下文,将终端当前服务的NH网络更新为新的NHN-ID(即第二网络标识)。其中,终端的上下文信息包含终端原先通过认证的PSP-ID及终端的安全上下文信息。MME成功获取终端的上下文信息后,可以更新当前服务终端的NHN-ID,不用对终端重新进行鉴权,向SGW发送会话建立请求以在新的SGW中创建会话,或者向SGW发送修改承载请求以指示SGW当前终端注册的MME。若分组数据网关PGW向MME注册了位置报告事件,MME可在会话建立请求或修改承载请求消息中携带用户位置信息以指示终端当前所选择的服务NHN-ID,SGW将此信息转发给PGW,以便于PCC(策略控制和计费)针对当前服务终端的NHN-ID使用特定的PCC策略。若MME未能通过NHN-ID和GUTI成功获取UE的上下文,MME向UE发送TAU拒绝命令。UE收到MME发送的TAU拒绝命令后,可发起基于PSP的附着过程,在附着请求消息中携带PSP-ID,核心网重新对该UE进行鉴权和注册。
为了更清楚的说明本公开实施例提供的终端接入网络的方法,下面对所述第二网络标识与第一网络标识不同,所述第二网络标识不在第一网络标识的等同网络的网络标识集中,且所述第二服务提供商的标识与第一服务提供商的标识相同的情况进行描述,即PSP-ID未变,NHN-ID改变,且NHN-ID不是等同NHN-ID的情况,由于终端选择的NHN-ID不属于PSP的等同网络,终端需要发起基于PSP的附着过程在终端所选的PSP-ID中重新进行鉴权和网络注册,MME无需获取UE在网络中的上下文,因此UE在附着请求中只需携带所需注册的PSP-ID。当MME收到终端发送的附着请求后,根据附着请求消息中的PSP-ID确定对应的AAA(认证、授权和计费)服务器。MME通过该AAA服务器对UE进行鉴权和认证,若该UE成功通过该PSP-ID的
AAA服务器的鉴权及认证,MME为该终端建立默认承载。
本公开的一些实施例中,终端在第一服务提供商的认证、授权和计费服务器中的签约信息中包含第一网络标识的等同网络的网络标识集信息和第一服务提供商的等同服务提供商标识,表示终端注册到该第一服务提供商的等同服务提供商中并在等同网络中接入时,核心网可以共享终端的上下文信息,不用对终端重新认证。且终端在第一服务提供商的认证、授权和计费服务器中的签约信息中包含第一网络标识的等同网络的网络标识集信息,表示终端注册到该第一服务提供商并在等同网络中接入时,核心网可以共享终端的上下文信息,不用对终端重新认证。
如图9所示,本公开的一些实施例提供一种终端接入网络的方法,包括:
步骤51,与上述步骤11相同。
步骤52,当所述第二网络标识与第一网络标识不同,且所述第二网络标识在第一网络标识的等同网络的网络标识集中,且所述第二服务提供商的标识与第一服务提供商的标识不同,且所述第二服务提供商的标识在第一服务提供商的等同服务提供商的标识集中时,判断所述终端当前是否位于该终端保存的已注册跟踪区中的位置区域内;
步骤53,若所述终端位于所述已注册跟踪区中的位置区域内,向第二网络发送有携带有所述终端的GUTI的服务请求;
步骤54,若所述终端位于所述已注册跟踪区外的位置区域内,向第二网络发送有携带有所述终端的GUTI的位置区更新请求或者附着请求。
本公开的该实施例针对的是所述第二网络标识与第一网络标识不同,且所述第二网络标识在第一网络标识的等同网络的网络标识集中,且所述第二服务提供商的标识与第一服务提供商的标识不同,且所述第二服务提供商的标识在第一服务提供商的等同服务提供商的标识集中的情况,即PSP-ID变化,但PSP-ID为等同PSP-ID,NHN-ID变化,但NHN-ID也为等同NHN-ID,终端可发起服务请求过程,从空闲状态转移到连接状态,或者终端可发起TAU过程或基于GUTI的附着过程通知核心网终端的服务位置区域发生了改变。
如图10所示,具体的,当终端位于已注册TA的位置区域时,当有业务到达或接收到寻呼消息时,终端可发起服务请求SR过程,以便从空闲状态转移到连接状态;当终端进入不属于已注册TA的位置区域时,终端可发起TAU过程或基于GUTI的附着过程通知核心网终端的服务位置区域发生了改变。其中,在本实施例中,终端的已注册TA的位置区域只包括第一网络的等同网络的位置区域。由于PSP-ID发生变化,终端发送的TAU请求或附着请求消息中还可携带新的PSP-ID,MME收到UE发送的新的PSP-ID,更新终端当前服务的PSP-ID,可以不用对终端重新进行鉴权和网络注册。且TAU请求或附着请求中携带核心网在原来的NHN-ID下为终端分配的GUTI。当MME收到终端发送的TAU请求或附着请求后,根据GUTI向原先终端注册的MME请求终端的上下文,将终端当前服务的NH网络更新为新的NHN-ID(即第二网络标识)。其中,终端的上下文信息包含终端原先通过认证的PSP-ID及终端的安全上下文信息。MME成功获取终端的上下文信息后,可以更新当前服务终端的NHN-ID,不用对终端重新进行鉴权,向SGW发送会话建立请求以在新的服务网关SGW中创建会话,或者向SGW发送修改承载请求以指示SGW当前终端注册的MME。若分组数据网关PGW向MME注册了位置报告事件,MME可在会话建立请求或修改承载请求消息中携带用户位置信息以指示终端当前所选择的服务NHN-ID,SGW将此信息转发给PGW,以便于PCC(策略控制和计费)针对当前服务终端的NHN-ID使用特定的PCC策略。若MME未能通过NHN-ID和GUTI成功获取UE的上下文,MME向UE发送TAU拒绝命令。UE收到MME发送的TAU拒绝命令后,可发起基于PSP的附着过程,在附着请求消息中携带PSP-ID,核心网重新对该UE进行鉴权和注册。

所选择的PSP-ID不属于等同PSP-ID或NHN-ID不属于等同NHN-ID,终端需要发起基于PSP的附着过程在终端所选的PSP-ID中重新进行鉴权和网络注册,MME无需获取UE在网络中的上下文,因此UE在附着请求中只需携带所选择的PSP-ID。当MME收到终端发送的附着请求后,根据MF接入点消息可获取当前终端选择的NHN-ID,根据附着请求消息中的PSP-ID确定对应的AAA服务器。MME通过该AAA服务器对UE进行鉴权和认证,UE通过该PSP-ID的AAA服务器的鉴权及认证后MME为该UE建立默认承载。
本公开的一些实施例中,终端在第一服务提供商的认证、授权和计费服务器中的签约信息中包含第一服务提供商的等同服务提供商信息,表示终端注册到该第一服务提供商的等同服务提供商并且NHN不变时时,核心网可以共享终端的上下文信息,不用对终端重新认证。

步骤61,与上述步骤11相同。
步骤62,当所述第二服务提供商的标识与第一服务提供商的标识不同,且所述第二服务提供商的标识在第一服务提供商的等同服务提供商的标识集中,且所述第二网络标识与第一网络标识相同时,向所述第二网络发送携带有所述终端的GUTI的接入请求。
具体的,当所述第二服务提供商的标识与第一服务提供商的标识不同,且所述第二服务提供商的标识在第一服务提供商的等同服务提供商的标识集中,且所述第二网络标识与第一网络标识相同时,判断所述终端当前是否位于该终端保存的已注册跟踪区中的位置区域内;

若所述终端位于所述已注册跟踪区外的位置区域内,向第二网络发送有携带有所述终端的全局唯一临时标识GUTI的位置区更新请求或者附着请求。
本公开的该实施例针对的是所述第二服务提供商的标识与第一服务提供商的标识不同,且所述第二服务提供商的标识在第一服务提供商的等同服务
提供商的标识集中,且所述第二网络标识与第一网络标识相同的情况,即PSP-ID变化,但PSP-ID为等同PSP-ID,NHN-ID未变的情况,终端可发起服务请求过程,从空闲状态转移到连接状态,或者终端可发起TAU过程或基于GUTI的附着过程通知核心网终端的服务位置区域发生了改变。
如图12所示,具体的,当终端位于已注册TA的位置区域时,当有业务到达或接收到寻呼消息时,终端可发起服务请求SR过程,以便从空闲状态转移到连接状态;当终端进入不属于已注册TA的位置区域时,终端可发起TAU过程或基于GUTI的附着过程通知核心网终端的服务位置区域发生了改变。其中,在本实施例中,终端的已注册TA的位置区域只包括第一网络的位置区域。TAU请求或附着请求中携带核心网在原来的NHN-ID下为终端分配的GUTI。当MME收到终端发送的TAU请求或附着请求后,根据GUTI向原先终端注册的MME请求终端的上下文,将终端当前服务的NH网络更新为新的NHN-ID(即第二网络标识)。其中,终端的上下文信息包含终端原先通过认证的PSP-ID及终端的安全上下文信息。MME成功获取终端的上下文信息后,可以更新当前服务终端的NHN-ID,不用对终端重新进行鉴权,向SGW发送会话建立请求以在新的SGW中创建会话,或者向SGW发送修改承载请求以指示SGW当前终端注册的MME。若PGW向MME注册了位置报告事件,MME可在会话建立请求或修改承载请求消息中携带用户位置信息以指示终端当前所选择的服务NHN-ID,SGW将此信息转发给PGW,以便于PCC(策略控制和计费)针对当前服务终端的NHN-ID使用特定的PCC策略。若MME未能通过NHN-ID和GUTI成功获取UE的上下文,MME向UE发送TAU拒绝命令。UE收到MME发送的TAU拒绝命令后,可发起基于PSP的附着过程,在附着请求消息中携带PSP-ID,核心网重新对该UE进行鉴权和注册。
为了更清楚的说明本公开实施例提供的终端接入网络的方法,下面对所述第二服务提供商的标识与第一服务提供商的标识不同,且所述第二服务提供商的标识不在第一服务提供商的等同服务提供商的标识集中,且所述第二网络标识与第一网络标识相同的情况,即PSP-ID改变,PSP-ID不是等同PSP-ID,且NHN-ID未变的情况。具体来说,由于终端选择的PSP-ID不属
于之前注册PSP的等同PSP,UE需要发起基于PSP的附着过程在UE所选的PSP-ID中重新进行鉴权和网络注册,MME无需获取终端在网络中的上下文,因此终端在附着请求中只需携带所需注册的PSP-ID。当MME收到终端发送的附着请求后,根据附着请求消息中的PSP-ID确定对应的AAA服务器。MME通过该AAA服务器对终端进行鉴权和认证,若该终端成功通过该PSP-ID的AAA服务器的鉴权及认证,MME为该终端建立默认承载。
需要说明的是,在本实施例所提供的技术方案中,只要所述第二网络标识标识与第一网络标识不同,无论所述第二服务提供商标识与第一服务提供商标识是否相同,终端都需要发起基于PSP的附着过程在新的PSP-ID中进行鉴权和网络注册。由于MME无需获取终端在网络中的上下文,终端在附着请求中只需携带所选择的新的PSP-ID。当MME收到终端发送的附着请求后,根据附着请求消息中的PSP-ID确定对应的AAA服务器。MME通过该AAA服务器对终端进行鉴权和认证,终端通过该PSP-ID的AAA服务器成功鉴权及认证后,MME为该终端建立默认承载和网络注册。
