Abstract
Disclosed herein is a method and corresponding system to help a wireless communication device (WCD) stay within a home system's network coverage after an access attempt failure. According to one embodiment of the method, a WCD receives a channel list message (CLM) in a given coverage area and transmits an access attempt on a carrier listed in the received CLM. Upon the failure of such an access attempt, the WCD may transmit an additional access attempt on another carrier listed in the received CLM, rather than switching over to a roaming system. According to another embodiment, a WCD receives a channel list message (CLM) in a given coverage area and transmits an access attempt on a carrier listed in the received CLM. Upon the failure of such an access attempt, the WCD may transmit an additional access attempt on another carrier not listed in the received CLM, rather than switching over to a roaming system. According to yet another embodiment, a WCD receives a CLM from a first coverage area and thereafter moves into a second coverage area and subsequently receives a CLM from the second coverage area. The WCD transmits an access attempt on a carrier listed in the second CLM and upon …
