当网络通过使用临时移动用户识别符(TMUI)进行寻呼时，相应的移动台(MS)发送一个应答。此后，网络通过使用相应于TMUI和随机数的鉴权密钥进行鉴权。当用户由鉴权被证明为非合法时，网络发送一个请求，用户应当发送单独的移动用户识别符(IMUI)。然后，网络通过使用相应于IMUI和随机数的鉴权密钥进行鉴权(S8-S10)。当用户被识别为合法用户时，再次分配TMUI。通过在MS与网络侧之间的协商，确定要被隐藏的目标和用于控制被包括在要被发送的信息中的隐藏开始时间的隐藏方法。当呼叫发生时，开始分集越区切换。当在MS处需要支路交换时，该支路被切换到有可能进行分集越区切换的支路。当在能够同时处理多个呼叫的MS处发生另一个呼叫时，对于所有的呼叫，支路配置和通信频带都被做成相同的。当在能够同时处理多个呼叫的MS处出现另一个呼叫时，选择使得所有的呼叫得以保持的支路配置和通信频带，并进行到这些支路配置和通信频带的转移。这样，移动通信系统可被构建成适合于发送各种类型的数据，由此，适用于多媒体通信。 The present invention relates to a method for determining a radio zone and an uplink transmission power, comprising transmitting, by each of base stations, broadcast information via a corresponding perch channel, the broadcast information indicating a specified channel transmission power level and an uplink interference level; and receiving, by a mobile station, the broadcast information from near base stations around the mobile station; detecting, by the mobile station, respective reception levels of the perch channels for the near base stations; calculating, by the mobile station, respective path losses between the mobile station and respective near base stations on the basis of the respective reception levels and the respective specified channel transmission power levels indicated by the broadcast information; calculating, by the mobile station, respective necessary uplink transmission power levels between the mobile station and respective near base stations on the basis of the calculated respective path losses, the respective uplink interference levels indicated by the mobile station, the broadcast information, and required signal-to-interference ratios involved in reception by the near base stations; selecting, by the mobile station, a radio zone in which the necessary uplink transmission power level is minimum among the respective necessary uplink transmission power levels, the base station of the selected radio zone being ready for communication with the mobile station or being able to commence communication with the mobile station after handover; and controlling, by the mobile station, an uplink transmission power in the selected radio zone based on the necessary uplink transmission power level of the selected radio zone.
