Abstract: A method of reducing an audio gap in a signal connection with a communication unit during handoff in a cellular communication system is provided. The method includes the steps of providing a temporary signal connection (17) with the communication unit (11) from a mobile switching center (MSC) (12) of a source base site, through the source base site (15-16) to a handoff target base site (18-19) and establishing a trunk connection (14) from the MSC of the source base site to an MSC of the target base site. The method further includes the step of interconnecting (33), at the target base site, the temporary signal connection, trunk connection, and communication unit; and re-routing the signal connection with the communication unit through the trunk connection.

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.
