    • A method of message management is provided for use with a mobile communications device having core and protected memories. The mobile communications device is in communication with a radio telecommunications system comprised of authorized and unauthorized radio telecommunications system operators, each operator have a unique identification code which is associated with messages communicated therefrom. The method of message management includes the step of storing the identification code of the authorized system operator in the core memory, receiving a message with an identification code associated therewith from the radio telecommunications system, and comparing the identification code of the message with the identification code of the authorized system operator. The method further includes the step of storing the message in the protected memory only if the identification code of the message matches the identification code of the authorized system operator. An apparatus is also provided for practicing the above mentioned method.
    • 提供了一种消息管理方法,用于具有核心和受保护存储器的移动通信设备。 移动通信设备与由授权的和未授权的无线电电信系统运营商组成的无线电电信系统进行通信,每个运营商具有与从其传送的消息相关联的唯一识别码。 消息管理的方法包括:将核心存储器中的授权系统运营商的识别码存储在无线电信系统中,从无线电电信系统接收具有与之相关联的识别码的消息,并将该消息的识别码与识别码进行比较 的授权系统操作员。 该方法还包括仅当消息的识别码与授权系统操作者的识别码匹配时才将消息存储在受保护存储器中的步骤。 还提供了一种用于实施上述方法的装置。

    • A cellular mobile telecommunication system includes a mobile station communicating with any one of a plurality of geographically spaced base stations, the base stations communicating with a mobile switching center to selectively determine one of the base stations to process a call with the mobile station. A handoff system hands off a cellular call with the mobile station from one base station to another base station. The handoff system includes a forward communication channel selectively associated with the one base station for transferring data from the one base station to the mobile station. The one base station is adapted to receive a command from the mobile switching center to handoff processing of the call to another base station, the command including information on capabilities of another base station. A message generator operatively associated with the one base station sends a capability change indicator to the mobile station via the forward communication channel and responds to a handoff command from the mobile switching center. The capability change indicator includes information on capabilities of the another base station relative to the one base station.
    • 蜂窝移动电信系统包括与多个地理上间隔的基站中的任何一个通信的移动站,基站与移动交换中心通信以选择性地确定基站之一来处理与移动站的呼叫。 切换系统将移动台的蜂窝呼叫从一个基站切换到另一个基站。 切换系统包括选择性地与一个基站相关联的前向通信信道,用于将数据从一个基站传送到移动站。 一个基站适于接收来自移动交换中心的命令以切换对另一基站的呼叫处理,该命令包括关于另一个基站的能力的信息。 可操作地与一个基站相关联的消息发生器经由前向通信信道向移动台发送能力改变指示符,并响应来自移动交换中心的切换命令。 能力改变指示符包括关于另一基站相对于一个基站的能力的信息。
