Abstract: An apparatus and method for clock rate matching in independent networks is disclosed. The apparatus accepts data from a modem (126) into a buffer (400) and determines the difference between the rate of the data entering the buffer (400) at the modem clock rate to the rate of data exiting the buffer (400) at the clock rate used by the apparatus. Depending on the rate difference, the apparatus either speeds up or slows down the data rate accordingly.

Abstract: A communication system provides data packet timing alignment to facilitate soft handoff. A vocoder (315) transmits compressed voice frames to base-stations (130,131) along links (110,112) of variable length, DELTA L. The DELTA L translates to a delay DELTA t in the air-frames to be transmitted by the base-stations (130,131). To compensate for the time delay DELTA t, the communication system advances both sets of air-frames to be transmitted by base-stations (130,131) by at least DELTA t so that skipping of frames, relative to an air-frame reference (300), during transmission does not occur.

Abstract: The clock rate matching appts for independent networks includes a memory (400), microprocessor (405) and a digital signal processor (406). A PCM signal is received by an analog/PCM block (124) and the clock (CLK1) extracted by a modem (126). The modem extracts the data and passes it to a memory (400) at the extracted clock speed. The data is clocked out of the buffer by a separate clock (CLK2). The difference in clock speeds is measured by the movement of the buffer pointers. In order to match the two clock rates, bits are added or deleted from the exit path of the memory.
