Description

用户设备的注册方法、 无线网络控制器和用户设备 技术领域 本发明涉及通信技术领域, 尤其涉及一种用户设备的注册方法、 无线 网络控制器和用户设备。 背景技术
第三代合作项目( 3rd Generation Partnership Project;以下简称: 3GPP ) 在 R6协议中引入了多运营商核心网 ( Multi-Operator Core Network; 以下 简称: MOCN )特性, 用以支持多运营商共享网络, 以降低运营商的建网 成本投入。
对于支持 MOCN的用户设备( User Equipment; 以下简称: UE )来说, 该支持 MOCN的 UE可以获知小区广播的多个公共陆地移动网络(Public Land Mobile Network; 以下简称: PLMN ) , 并在发送给无线网络控制器 ( Radio Network Controller; 以下简称: RNC )的初始直传( INIT DIRECT TRANSFER ) 消息中携带上述 UE选择的 PLMN。 然后, RNC 直接将该 UE路由到其选择的 PLMN对应的核心网( Core Network; 以下简称: CN )。
由于运营商的需求, 在实际应用中, 可能存在如下的组网场景: 1 )运营商 A拥有第二代移动通信 ( 2nd Generation; 以下简称: 2G ) 网络, 运营商 B无 2G网络, 运营商 B的用户可以在运营商 A的 2G网络 中漫游;
2 )运营商 A和运营商 B组成第三代移动通信 ( 3rd Generation; 以下 简称: 3G ) 的 MOCN, 运营商 A和运营商 B的 3G不能相互漫游。
假设支持 MOCN的 UE在运营商 B签约 , 在运营商 A的 2G的小区 驻留后, 小区重选到运营商 A和运营商 B共享的 MOCN小区。根据协议, 上述支持 MOCN 的 UE 在 MOCN 的小区注册时, 会在 INIT DIRECT TRANSFER消息中携带该 UE上次注册的 PLMN (即运营商 A ) , 于是 RNC会将上述 UE路由到运营商 A的 CN。 由于运营商 A和运营商 B的 3G不能相互漫游, 因此 UE注册失败。 也就是说, 当共享小区存在 UE的注册 PLMN ( Registered PLMN; 以 下简称: RPLMN )和归属 PLMN ( Home PLMN; 以下简称: HPLMN )时 , 现有技术中,支持 MOCN的 UE应该优选 RPLMN,这样会存在以下问题: MOCN小区中的 RPLMN不一定接受 UE的请求, 如上所述, 运营商 B的 用户可以在运营商 A的 2G网络漫游, 但是不能在运营商 A的 3G漫游; 这样, UE无法注册成功。 发明内容

图 1为本发明用户设备的注册方法一个实施例的流程图,如图 1所示, 该用户设备的注册方法可以包括:
TRANSFER ) 消息 , 该初始直传消息携带 UE选择的 PLMN。
其中, 该 UE选择的 PLMN为 UE最近一次成功注册的 PLMN。
步骤 102, RNC向组成上述 MOCN的运营商的核心网发送重定向请 求, 并接收接受重定向请求的运营商的核心网给 UE下发的 PLMN。
其中, 上述重定向请求中携带 UE选择的 PLMN; 上述接受重定向请 求的运营商的核心网给 UE下发的 PLMN为 UE选择的 PLMN。 具体地, RNC可以向 UE选择的 PLMN对应的第一运营商的核心网 发送重定向请求, 该重定向请求携带 UE选择的 PLMN; 然后, RNC接收 第一运营商的核心网发送的重定向拒绝消息, 上述重定向拒绝消息中携带 的原因值为位置区不允许; 上述重定向拒绝消息是第一运营商的核心网接 收到上述重定向请求, 确定不允许 UE在第一运营商的核心网漫游之后发 送给上述 RNC的。
接下来, RNC向组成上述 MOCN的运营商的核心网中除第一运营商 的核心网之外的第二运营商的核心网发送重定向请求, 上述重定向请求携 带 UE选择的 PLMN; 然后, RNC接收第二运营商的核心网发送的非接入 层接受消息, 上述非接入层接受消息中携带第二运营商的核心网给 UE下 发的 PLMN; 上述非接入层接受消息是第二运营商的核心网接收到重定向 请求,确定第二运营商的核心网为上述 UE的归属 PLMN对应的运营商的 核心网或者确定允许上述 UE在第二运营商的核心网漫游之后发送给 UE 的。
本实施例中, RNC可以先向 UE选择的 PLMN对应的第一运营商的 核心网发送重定向请求, 接收到第一运营商的核心网发送的重定向拒绝消 息之后, 再向组成上述 MOCN 的运营商的核心网中除第一运营商的核心 网之外的第二运营商的核心网发送重定向请求。 如果上述 MOCN是由至 少三个运营商组成的, 也就是说, 除第一运营商之外还包括至少两个第二 运营商, 第二运营商不唯一, 则 RNC先向 UE选择的 PLMN对应的第一 运营商发送重定向请求, 接收到第一运营商的核心网发送的重定向拒绝消 息之后, RNC重复上述过程, 依次向组成 MOCN的运营商中除第一运营 商之外的每个第二运营商发送重定向请求, 直至接收到非接入层接受消息 为止。
需要说明的是, 如果第一运营商包括至少两个核心网, 则 RNC只需 向第一运营商包括的一个核心网发送重定向请求即可, 而不用给第一运营 商的每个核心网均发送重定向请求; 同理, 如果第二运营商包括至少两个 核心网, 则 RNC只需向第二运营商包括的一个核心网发送重定向请求即 可, 而不用给第二运营商的每个核心网均发送重定向请求。 也就是说, 对 于每个运营商, RNC只需发一次重定向请求。
步骤 103 , RNC向 UE发送下行直传( DL DIRECT TRANSFER )消息, 上述下行直传消息中携带接受上述重定向请求的运营商的核心网给 UE下 发的 PLMN。
具体地, 上述下行直传消息中携带接受上述重定向请求的运营商的核 心网给 UE下发的 PLMN可以为: 上述下行直传消息中携带非接入层接受 消息, 上述非接入层接受消息的位置区指示(Location Area Identity; 以下 简称: LAI ) 字段中携带的 PLMN为接受重定向请求的运营商的核心网给 UE下发的 PLMN。
上述实施例中, RNC接收支持 MOCN的 UE发送的初始直传消息之 后, 向组成 MOCN 的运营商的核心网发送重定向请求, 并接收接受上述 重定向请求的运营商的核心网给上述 UE 下发的 PLMN; 最后, RNC 向 UE 发送下行直传消息, 该下行直传消息中携带上述接受重定向请求的运 营商的核心网给该 UE下发的 PLMN, 上述接受重定向请求的运营商的核 心网给该 UE下发的 PLMN为上述 UE选择的 PLMN; 从而可以保证运营 商的核心网下发的 PLMN与 UE请求的 PLMN—致,这样 UE就可以注册 成功, 避免了 UE掉网, 提升了用户感受。
图 2为本发明用户设备的注册方法另一个实施例的流程图, 如图 2所 示, 该用户设备的注册方法可以包括:
步骤 201 , 支持 MOCN的 UE向 RNC发送初始直传消息, 上述初始 直传消息携带 UE选择的 PLMN。
其中, 上述 UE选择的 PLMN为该 UE最近一次成功注册的 PLMN。 步骤 202, UE接收 RNC发送的下行直传消息, 上述下行直传消息中 携带的 PLMN为 UE选择的 PLMN。
上述实施例可以保证运营商的核心网下发的 PLMN 与 UE 请求的
PLMN—致, 这样 UE就可以注册成功, 避免了 UE掉网, 提升了用户感 受。
本发明图 1和图 2所示实施例提供的方法可以应用在如下场景中: 1 )运营商 A拥有 2G网络, 运营商 B无 2G网络, 运营商 B的用户 可以在运营商 A的 2G网络中漫游; 2 )运营商 A和运营商 B的 3G网络组成 3G的 MOCN, 运营商 A和 运营商 B的 3G网络不能相互漫游。
假设支持 MOCN的 UE在运营商 B签约, 在运营商 A的 2G的小区 驻留后, 小区重选到运营商 A和运营商 B共享的 MOCN小区。根据协议, 上述支持 MOCN的 UE在 MOCN的小区注册时, 会在初始直传消息中携 带该 UE上次注册的 PLMN (即运营商 A ) , 于是 RNC会将上述 UE路由 到运营商 A的 CN。 由于运营商 A和运营商 B的 3G不能相互漫游, 因此 UE注册失败。
本发明提供用户设备的注册方法可以解决上述问题, 图 3为本发明用 户设备的注册方法再一个实施例的流程图, 如图 3所示, 该用户设备的注 册方法可以包括:
步骤 301 , 支持 MOCN的 UE向 RNC发送初始直传消息, 该初始直 传消息携带 UE选择的 PLMN。
其中, 该 UE选择的 PLMN为 UE最近一次成功注册的 PLMN, 本实 施例中 , UE最近一次成功注册的 PLMN为运营商 A的 PLMN。
步骤 302, RNC将上述支持 MOCN的 UE当作不支持 MOCN的 UE ( Non- Supporting UE ) 进行处理, 启动重定向机制, RNC向运营商 A的 PLMN对应的核心网发送初始用户设备消息 ( INIT UE MESSAGE ) 。
其中, 上述初始用户设备消息即为重定向请求, 该初始用户设备消息 中携带 UE选择的 PLMN , 即该初始用户设备消息中携带的 PLMN为运营 商 A的 PLMN;具体地,该初始用户设备消息中携带的 PLMN为运营商 A 的 PLMN可以为: 该初始用户设备消息的 LAI字段中携带的 PLMN为运 营商 A的 PLMN。
步骤 303 ,运营商 A的 PLMN对应的核心网向 RNC发送直传( DIRECT TRANSFER )消息, 该直传消息中携带重定向拒绝消息, 该重定向拒绝消 息中携带的原因值为位置区不允许。
具体地, 运营商 A的 PLMN对应的核心网接收到 RNC发送的初始用 户设备消息之后, 发现上述 UE为签约运营商 B的 3G用户, 而运营商 A 和运营商 B的 3G不能相互漫游,因此运营商 A的 PLMN对应的核心网不 允许 UE在运营商 A的 PLMN对应的核心网漫游,于是运营商 A的 PLMN 对应的核心网向 RNC发送重定向拒绝消息。
步骤 304 , RNC向运营商 B的核心网发送初始用户设备消息。
其中, 上述初始用户设备消息即为重定向请求, 该初始用户设备消息 中携带 UE选择的 PLMN , 即该初始用户设备消息中携带的 PLMN为运营 商 A的 PLMN;具体地,该初始用户设备消息中携带的 PLMN为运营商 A 的 PLMN可以为: 该初始用户设备消息的 LAI字段中携带的 PLMN为运 营商 A的 PLMN。
步骤 305 , 运营商 B的核心网向 RNC发送直传消息, 该直传消息携 带重定向成功消息和非接入层( Non-Access Stratum; 以下简称: NAS )接 受消息。
具体地, 运营商 B的核心网接收到 RNC发送的初始用户设备消息之 后, 发现上述 UE为签约运营商 B的 3G用户, 于是运营商 B接受上述重 定向请求, 向 RNC发送直传消息, 并在该直传消息中携带重定向成功消 息和 NAS接受消息, 该 NAS接受消息携带运营商 B的核心网给 UE下发 的 PLMN; 具体地, 该 NAS接受消息携带运营商 B的核心网给 UE下发 的 PLMN可以为: 该 NAS接受消息中的 LAI字段携带运营商 B的核心网 给 UE下发的 PLMN; 上述运营商 B的核心网给 UE下发的 PLMN即为上 述 UE选择的 PLMN, 也就是运营商 A的 PLMN。
步骤 306, RNC向 UE发送下行直传( DL DIRECT TRANSFER )消息, 该下行直传消息携带上述 NAS接受消息。
其中, 该 NAS接受消息携带运营商 B的核心网给 UE下发的 PLMN。 具体地, 该 NAS接受消息携带运营商 B的核心网给 UE下发的 PLMN可 以为: 该 NAS接受消息中的 LAI字段携带运营商 B的核心网给 UE下发 的 PLMN; 上述运营商 B的核心网给 UE下发的 PLMN即为上述 UE选择 的 PLMN, 也就是运营商 A的 PLMN。 这样, 运营商 B的核心网给 UE下 发的 PLMN与该 UE选择的 PLMN—致 , 因此该 UE注册成功 , 注册流程 结束。
需要说明的是, 如果组成 MOCN的除运营商 A之外, 还包括至少两 个运营商, 则在接收到运营商 A 的核心网发送的重定向拒绝消息之后, RNC顺序向上述至少两个运营商中的每个运营商发送重定向请求,直至接 收到 NAS接受消息为止。如果上述至少两个运营商中不包括 UE签约的运 营商, 那么允许 UE漫游的运营商也会接受 RNC的重定向请求, 向 RNC 发送 NAS接受消息。
上述实施例中, RNC在组成 MOCN的运营商中釆用重定向机制为 UE 选择可服务的运营商, 同时接受重定向请求的运营商的核心网在 NAS接 受消息中下发的 PLMN为 UE在初始直传消息中携带的 PLMN,从而可以 保证运营商的核心网下发的 PLMN和 UE请求的 PLMN—致,这样 UE就 可以注册成功, 避免了 UE掉网, 提升了用户感受。
