Abstract: A system (100) includes a mobile station (125) to initiate an outgoing communication anywhere in a coverage area (115). A base station (110) and a radio access network (105) provide wireless service to the mobile station (125). The mobile station is paged in the sectors overlapping with only the clean zone. The mobile station (125) is paged in the sectors overlapping with the hot zone if the mobile station has predetermined trusted characteristics, or the mobile station is located within a clean zone of sectors overlapping with the hot zone, and an incoming communication for the mobile station originates from a predetermined trusted source. Existing calls to the mobile station are terminated in response to the existing call exceeding a predetermined threshold time limit, or a detected amount of voice activity in the existing call being below a predetermined threshold level.

Abstract: A security method (100) in a radio access network can include monitoring (102) (by either a base station controller or a mobile radio) for one or more abnormalities among CPU utilization, memory storage, memory read-write, malicious incoming or outgoing messages, and virus file names, notifying (104) of a specific abnormality detected, and receiving (108) access, conditional access or limited access based on the specific abnormality detected. The method can further include receiving updates (112) used for monitoring the abnormalities. The method can further include the optional step (106) of issuing a notification from a mobile radio to a base station controller if the specific abnormality is detected and suspending (110) one or more services based on the specific abnormality detected. The method can further include receiving (114) at the mobile radio an over the air programming instruction to suspend a specific service and alerting the mobile radio.
