Abstract:
1. A method of operating a communication system, the method comprising: in a mobile switching center, determining a first delay metric for first traffic transmitted on a first path to the mobile switching center from a first base station, wherein the first delay metric is determined from a difference in time between when a first timing message is sent from the first base station and when the first timing message is received at the mobile switching center; in the mobile switching center, determining a first delay differential based on the first delay metric and a second delay metric for second traffic transmitted on a second path to the mobile switching center from a second base station, wherein the second delay metric is determined from a difference in time between when a second timing message is sent from the second base station and when the second timing message is received at the mobile switching center and wherein the first delay differential is determined from the difference in time between the first delay metric and the second delay metric; transmitting a control message indicating the first delay differential from the mobile switching center to the second base station; receiving the control message at the second base station; and in response to receiving the control message, in the second base station, delaying the second traffic based on the first delay differential.
