Abstract:
1. A method comprising: an access terminal transmitting a first route-update message to a first base station, wherein the first base station is associated with a first route-update-radius; the access terminal determining that a distance between the first base station and a second base station exceeds the first route-update-radius and the access terminal determining whether an occupancy of a channel to or from the second base station exceeds a channel occupancy threshold; if the access terminal determines that the occupancy of the channel to or from the second base station does not exceed the channel occupancy threshold, then the access terminal transmitting a second route-update message to the second base station without performing a transmission delay; and if the access terminal determines that the occupancy of the channel to or from the second base station exceeds the channel occupancy threshold, then the access terminal determining whether the access terminal is mobile, and if the access terminal determines that the access terminal is mobile, then the access terminal transmitting the second route-update message after performing the transmission delay, otherwise, if the access terminal determines that the access terminal is not mobile, then the access terminal transmitting the second route-update message to the second base station without performing the transmission delay.
