Timing compensation method and means for a terrestrial wireless communication system having satelite backhaul link
First Claim
1. A timing compensation method used in a terrestrial wireless communication system having at least one satellite backhaul link to at least one base transceiver station (BTS), comprising:
- establishing a backhaul delay (BHD) of one of the at least one satellite backhaul link (SBL);
determining a real time;
setting a base controller system time to the real time;
generating a modified controller system time by adding the BHD to the base controller system time; and
transmitting a forward data frame over the one of the at least one SBL to the one of the at least one BTS according to a frame sequence number of the forward data frame, a forward data frame offset of the one of the at least one BTS, and the modified controller system time.

Abstract
A technique for timing compensation is used in a terrestrial wireless communication system (300) that has a satellite backhaul link (352, 358, 360) to at least one base transceiver station (306, 307, 308). The technique includes establishing a backhaul delay (BHD) of the satellite backhaul link and performing at least one timing compensation function based on the backhaul delay. The technique further includes setting (540, 545) a base controller system time (170). The following timing compensation functions are described: adjustment of packet arrival timing error interval (520), selection of a mobile station power control outer loop path (525), adjustment of at least one protocol timer (530), evaluation of a reverse Markov test call frame based on the BHD and real time (545), adjustment of forward data frame alignment based on the BHD and real time (555), and adjustment of forward Markov test call frame generation based on the BHD and real time (560).
