Abstract

A personal base station configured to connect to the Internet and establish a small area of wireless coverage including means for controlling interference with neighboring personal base stations using a timeslot management mechanism. Timeslot management mechanisms include timeslot interference detection, timeslot power reduction, timeslot allocation, timeslot offset calibration, and timeslot synchronization management that minimizes the number of frequencies required to control inter-cell interference between neighboring personal base stations.

Claims

1. A personal base station configured to connect to the Internet and establish a small area of wireless coverage comprising:

means for controlling interference with neighboring personal base stations using a timeslot management mechanism.

2. A personal base station as claimed in claim 1, wherein the timeslot management mechanism comprises selecting non-interfering timeslots for mobile service requests.

3. A personal base station as claimed in claim 1, wherein the timeslot management mechanism comprises decreasing power on interfering timeslots and increasing power on non-interfering time slots.

4. A personal base station as claimed in claim 1, wherein the timeslot management mechanism comprises offsetting its broadcast control channel to avoid interference with neighboring broadcast control channels.

5. A personal base station as claimed in claim 1, wherein the timeslot management mechanism comprises synchronizing TDMA timeslots with those of neighboring PBS units to avoid interference problems associated with timeslot frequency drift.

6. A personal base station as claimed in claim 1, and further comprising an interference database for tracking-TCH and BCCH timeslot interference with neighboring personal base stations.
