Abstract The present invention relates to an equipment for implementing first-layer protocol of personal hand-held communication system and its method. Said equipment comprises signaling controller, data frame processor, interface adapter and baseband modem, and its method includes data receiving processing process and data transmitting processing process. The data frame processor can directly combine or separate informatino field in the data frame, and can read and write speech channel correspondent port when the time slot is being in speech transmission state, and can exchange data with signaling controller in asynchronous mode, and the system clock refers to local clock source, so that it can use low-performance hardware to implement higher reliability, at the same time can reduce cost.
