Abstract
A method and system for synchronizing scan opportunities in a mobile communications system. Time slots are sent between a mobile subscriber and an associated base station wherein the mobile subscriber corresponds to a scan group. The number of time slots sent between the mobile subscriber and the associated base station is counted. Based upon the count, the scan group of the mobile subscriber, a scan rate, and a scan opportunity divisor, a scan opportunity is determined. If it is a scan opportunity, a scan is performed of a neighboring base station.
Claims20
A method for synchronizing scan opportunities in a mobile communications system comprising the steps of:
- sending time slots between a mobile subscriber and an associated base station wherein the mobile subscriber has a corresponding scan group;
- counting the number of time slots sent between the mobile subscriber and the associated base station;
- and
- determining whether it is a scan opportunity based upon the count, the scan group of the mobile subscriber, a scan rate, and a scan opportunity divisor and if it is a scan opportunity, then performing a scan of a neighboring base station.
A system for synchronizing scan opportunities in a mobile communications system comprising:
- an associated base station configured to keep a first count of a number of time slots sent between the base station and a mobile subscriber;
- the mobile subscriber configured to receive communications from the associated base station and configured to keep a second count of a number of time slots sent between the base station and the mobile subscriber;
- a processor for determining a scan opportunity based upon the first count and the second count, a scan group of the mobile subscriber, a scan rate, and a scan opportunity divisor, wherein
- the mobile subscriber scans to a neighboring base station on a scan opportunity.
A system for synchronizing scan opportunities in a mobile communications system comprising:
- means for sending time slots between a mobile subscriber and an associated base station wherein the mobile subscriber has a corresponding scan group;
- means for counting the number of time slots sent between the mobile subscriber and the associated base station;
- and
- means for determining whether it is a scan opportunity based upon the count of frames, the scan group of the mobile subscriber, a scan rate, and a scan opportunity divisor.
