Abstract
In a wireless communications system, upon making a decision to roam, the mobile chooses an alternate communications channel in a prioritized manner and evaluates the chosen channel for whether it is able to support a data link interconnection. Upon evaluating that a chosen channel is able to support a data link connection, the chosen channel is selected as the next best alternate channel on which to attempt a data link establishment procedure. The channels are chosen from a set of possible channels in an order including a home channel, an in area channel, and then any of the possible channels. Advantageously, the selection of the next best alternate channel provides increased probability of establishing and maintaining a data link over the selected channel as well as providing a certain amount of control communications traffic flow in the system.
