    • PURPOSE: A method and an apparatus for enabling mobile-to-mobile calls via a common relay station is provided to reduce the amount of delay present in the system as well as to allows for encryption of the signals transmitted to a form the mobile station. CONSTITUTION: A communication system includes a relay station(30) for communicating with the first and second wireless phones. A transponder means in the relay station(30) not only relays signals received from one mobile station on a first frequency band to another mobile station on a second frequency band, but also sends the received signals to a control means which controls the operation of the transponder means using control information. When a first mobile station(32) requests an enciphered connection with a second mobile station(34), the communication system determines whether the second mobile station(34) is only reachable by a satellite. When the second mobile station(34) is only reachable by a satellite, the communication system allocates a direct mobile-to-mobile transponder channel in the satellite for the call. In addition, the communication system sends the identification of the transponder channel and the enciphering codes to the first mobile station and informs the second mobile station(34) of the call identification of the transponder channel and the enciphering codes.
    • 目的:提供一种用于通过公共中继站实现移动电话到移动电话的方法和装置,以减少系统中存在的延迟量,并且允许对发送到移动台的形式的信号进行加密。 构成:通信系统包括用于与第一和第二无线电话进行通信的中继站(30)。 中继站(30)中的应答器装置不仅将在第一频带上从一个移动台接收的信号中继到另一个频带上的另一个移动台,而且还将接收到的信号发送到控制装置 转发器意味着使用控制信息。 当第一移动站(32)请求与第二移动站(34)的加密连接时,通信系统确定第二移动站(34)是否只能被卫星到达。 当第二移动站(34)仅由卫星可达时,通信系统在卫星中分配用于呼叫的直接移动台到移动应答器信道。 另外,通信系统向第一移动台发送应答器信道的标识和加密码,并向第二移动台(34)通知应答器信道的呼叫标识和加密码。
