Abstract
A base station (106) is connected to several communication servers (114, 116, 118) by a corresponding number of communication links (128). Should one or more of the connections fail, the base station comprises a base mobile radio (210) for scanning one or more neighbor cells (108-113) to determine their current service status. The neighbor cells have overlapping coverage with serving cell, but on different frequencies. The base station broadcasts a fault message along with the updated neighbor cell information to mobile stations (102), allowing the mobile stations to choose the most appropriate cell for the desired communication activity.
