APPARATUS, AND AN ASSOCIATED METHOD, FOR PRESERVING COMMUNICATION SERVICE QUALITY LEVELS DURING HAND-OFF OF COMMUNICATIONS IN A RADIO COMMUNICATION SYSTEM
First Claim
1. A method comprising:
- transmitting a stream of data packets through a communication channel;
determining that an interruption of the communication channel will occur; and
before the interruption occurs, inserting a number of delay packets into the stream of data packets, the number of delay packets corresponding to an estimated length of time the communication interruption is expected to last.

Abstract
A mobile station is configured to transmit a sequence of data packets over a wireless network. The station includes a data sequence expander. The expander receives an indication of a pending hand-off for the mobile station from a first network access point to a second network access point and estimates an amount of time prior to occurrence of the hand-off. The expander inserts a number of delay packets into the sequence of data packets in response to receiving the indication of the pending hand-off. The number of delay packets is determined based on the estimated amount of time prior to the occurrence of the hand-off such that the insertion of the delay packets into the sequence of data packets will cause a delay that corresponds to the amount of time prior to occurrence of the hand-off.

8. A method comprising:
-
transmitting a stream of data packets through a communication channel; determining that an interruption of the communication channel will occur; and before the interruption occurs, inserting delay packets into the stream of data packets to compensate for the expected interruption, the delay packets corresponding to silence and being inserted along the stream of data packets at locations corresponding to periods of silence. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method comprising:
-
receiving a stream of data packets over a communication channel; determining that delay packets have been inserted into the stream of data packets prior to an interruption of the stream of data packets; and after the interruption has ended, removing the delay packets from the stream of data packets. - View Dependent Claims (16, 17, 18, 19, 20)
