In addition, in the UE roaming scenario, if the number of operators roaming the UE is large, the available network list will be long, for example, there are many small operators in Hong Kong, the United States, some European countries, and elements in the available network list ( There are dozens of PLMN, RAT).

Description

漫游入网方法及装置
技术领域
本发明实施例涉及通信技术, 尤其涉及一种漫游入网方法及装置。 背景技术
用户设备 (User Equipment, 简称 UE) 开机后或者漫游时, 首要任务是 选择一个公共陆地移动网络 (Public Land Mobile Network, 简称 PLMN) 且 注册成功, 只有这样, UE才能获得通信服务, 例如通话、 传输数据。
UE 开机后, 首先尝试注册到用 UE上次成功注册的公用陆地移动网络 (Registered PLMN, 简称 RPLMN)。 若注册失败, 则 UE进行全频段搜网, 根据 UE所支持的频段及无线接入技术 (Radio Access Technologies, 简称 RAT) 搜索所有网络, 然后形成可用网络列表, 该列表中的每个元素都包括 一个可用网络的 PLMN和 RAT。 UE进行全频段搜网的时长, 主要取决于 UE 所支持的频段及 RAT、 UE所在区域的覆盖小区数量, 以及 UE的软硬件限制 等因素。
为了方便 UE更快地注册上可用网络, UE按照一定的规则, 在搜索到的 可用网络列表中选择 PLMN ; 其中, 在第三代移动通信伙伴项目 (3rd Generation Partnership Project, 简称 3GPP) 协议中就规定 UE按照如下顺序 选择 PLMN: 归属的公共陆地移动网络 (Home PLMN, 简称 HPLMN) -- > 用户控制的公共陆地移动网络 (User PLMN, 简称 UPLMN) ->运营商控 制的公共陆地移动网络 (Operator PLMN , 简称 OPLMN ) -- > 其他可用 PLMN ( OTHER Available PLMN) ; 例如, UE根据 HPLMN、 UPLMN、 OPLMN, 以及其他可用 PLMN 的信号质量, 为搜索到的可用网络列表中的 各可用网络设置优先级, 并将各可用网络按照优先级从高到低的顺序进行排 序; UE根据优先级依次选取各可用网络尝试进行注册, 直到注册成功。
对于每一个选取的可用网络, UE进行注册的过程中都会伴随着全网的 多轮信令消息交互, 而且, 当一次尝试注册失败后, UE还需要继续尝试注 册同一可用网络, 直到满足预设的停止条件, 例如尝试失败次数达到预设的 尝试失败次数阈值, 因此, UE 尝试注册一个可用网络的时延较大。 另外, 在 UE漫游场景中, 如果 UE漫游地的运营商数目很多, 则可用网络列表就会 很长, 例如在香港、 美国、 一些欧洲国家的小运营商较多, 可用网络列表中 的元素 (PLMN, RAT) 可以达到数十条。
现有技术中, UE在漫游地初始入网时, 需要经过较长时间才能够成功 注册到漫游地的网络, 由于等待时间过长, 影响用户体验。 发明内容

所述用户设备获取可注册成功的网络的列表的一种可行的实现方式为: 所述用户设备在所述用户设备的非易失性存储器中检测是否存储有所述可注 册成功的网络的列表; 若否, 则所述用户设备从所述云端获取所述云端存储 的可注册成功的网络的列表; 若是, 则所述用户设备从非易失性存储器中获 取可注册成功的网络的列表, 以及与所述云端进行所述可注册成功的网络的 列表的同歩, 使得所述用户设备的非易失性存储器中存储的可注册成功的网 络的列表与所述云端存储的可注册成功的网络的列表的版本信息 (例如同歩 标识、 时间戳) 一致。
进一歩, 所述用户设备在所述可注册成功的网络的列表发生更新后, 与 所述云端进行所述可注册成功的网络的列表的同歩, 将所述可注册成功的网 络的列表中存储信息的变化情况同歩上传给所述云端, 以更新所述云端存储 的可注册成功的网络的列表及版本信息。
可选的, 在上述实施例的基础上, 所述可注册成功的网络的列表存储 于用户识别模块 (SIM) 。 将所述可注册成功的网络的列表存储于用户识别 模块的一种可行的实现方式为: 在 SIM中增加一个新的基本文件 (Elementary File, 简称 EF) : 漫游 EF (EF-Roam), 该 EF-Roam用于存储用户的可注册 成功的网络的列表。
以所述可注册成功的网络的列表记录了历史漫游信息为例: 用户设备在 漫游地初始漫游入网时:
当收到注册成功或位置更新成功消息后, 将当前注册成功的可用网络的 信息保存到 EF-Roam中。
当用户设备的注册请求被拒绝时, 例如拒绝原因是 PLMN 不可用 (PLMN not allowed) , 则用户设备判断当前注册失败的可用网络是否记录 在 EF-Roam中; 若是, 则将其从 EF-Roam中删除。
可选的, 在 EF-Roam中设置有效时间字段。 当某个可用网络的信息被新 增到 EF-Roam中的同时启动一个有效时间, 当有效时间过期时, 从 EF-Roam 中自动删除该可用网络的信息。
可选的, 在上述实施例的基础上, 所述用户设备获取运营商支持的漫 游网络的信息的一种可行的实现方式为: 所述用户设备将从所述用户识别模 块, 和 /或所述云端, 和 /或所述用户设备的非易失性存储器中分别获取的 OPLMN列表进行合并, 形成整合后的 OPLMN列表。
