    • A wireless communication unit performs wireless communication with a network of a carrier and receives a roaming list transmitted from the network. A control unit causes a storing unit to store the transmitted roaming list. The control unit sets the stored roaming list to be workable when completing updating of the roaming list and traces a communicable wireless communication system using the workable roaming list. The control unit causes the wireless communication unit to transmit an update request to the network when reception of the transmitted latest roaming list is unsuccessful in the course of the reception and when a predetermined condition is satisfied. The network transmits a latest roaming list to the wireless communication unit in response to reception of the update request.
    • 无线通信单元与载波的网络进行无线通信,并接收从网络发送的漫游列表。 控制单元使存储单元存储所发送的漫游列表。 控制单元在完成漫游列表的更新时将存储的漫游列表设置为可行,并使用可行漫游列表跟踪可通信的无线通信系统。 当接收到发送的最新漫游列表在接收过程中不成功并且满足预定条件时,控制单元使得无线通信单元向网络发送更新请求。 响应于接收到更新请求,网络向无线通信单元发送最新的漫游列表。
