Patent ID: 7305012

Claim:
A method to synchronize at least a user equipment to at least one base transceiver station belonging to a digital telecommunication network, in which radio signals transmitted and received by said base transceiver station are subdivided into frames (Fn) having predefined duration and each frame is subdivided into a predefined number of timeslots (Tn) and codes (Cn), said signals including at least a synchronization signal (S), which is transmitted by the base transceiver station and contains a modulation elementary units sequence suitable to identify the timeslot (T 1 ) and the code (C 1 ) of a service channel containing a system messages (M), the method comprising: marking the synchronization signal (S), in at least one frame (Fx), by the base transceiver station; transmitting a pointer message (P) in the service channel of such frame (Fx), or of a subsequent frame (Fx+n), by the base transceiver station; detecting the marked synchronization signal (S′) by the user equipment; receiving the pointer message (P) by the user equipment; extracting from the pointer message (P) the position of at least a system message (M′) by user equipment, wherein the base transceiver station marks the synchronization signal to indicate to the user equipment the presence of a pointer message.
