Connection identifier reservation in a wireless communication system
View Patent ↗A wireless communication system allocates connection identifiers into a first group and a second group. The system associates sectors or base stations with a reservation zone, and associates the reservation zone with the first group of connection identifiers. The system associates the first group of connection identifiers with a quality-of-service level. In response to determining that a user has the quality-of-service level, the system reserves at least one of the connection identifiers in the first group for the user and uses the reserved connection identifier to communicate with the first user in all of the sectors or base stations associated with the reservation zone.
1. A method of operating a wireless communication system that has a plurality of sectors, the method comprising:
allocating, by a reservation system, connection identifiers into at least a first group of the connection identifiers and a second group of the connection identifiers;
associating, by the reservation system, a set of the sectors with a reservation zone, associating the reservation zone with the first group of the connection identifiers, and associating the first group of the connection identifiers with a quality-of-service level;
in response to a first service request from a first user, determining, by the reservation system, that the first user has the quality-of-service level, and in response, reserving one of the connection identifiers in the first group for the first user and using the reserved one of the connection identifiers in the first group to communicate with the first user in all of the sectors associated with the reservation zone;
in response to a second service request from a second user, determining, by the reservation system, that the second user does not have the quality-of-service level, and in response, using different ones of the connection identifiers in the second group to communicate with the second user in each one of the sectors.
2. The method of claim 1 further comprising:
transferring, by the reservation system, the reserved one of the connection identifiers in the first group to the first user for use throughout the reservation zone; and
transferring, by the reservation system, the different ones of the connection identifiers in the second group to the second user as the second user moves between the sectors associated with the reservation zone.
3. The method of claim 1 wherein the connection identifiers comprise worldwide interoperability for microwave access unicast connection identifiers.
4. The method of claim 1 wherein the connection identifiers comprise worldwide interoperability for microwave access service flow identifiers.
5. The method of claim 1 further comprising determining, by the reservation system, that the first group of the connection identifiers has a surplus and that the second group of the connection identifiers has a shortage, and in response, re-allocating at least one of the connection identifiers in the first group to the second group.
6. The method of claim 1 further comprising determining, by the reservation system, that the second group of the connection identifiers has a surplus and that the first group of the connection identifiers has a shortage, and in response, re-allocating at least one of the connection identifiers in the second group to the first group.
7. The method of claim 1 wherein the set of the sectors associated with the reservation zone include all of the sectors served by an access service network gateway in a worldwide interoperability for microwave access system.
8. The method of claim 1 wherein the set of the sectors associated with the reservation zone include the current sector occupied by the first user and all of the sectors that are adjacent to the current sector.
9. The method of claim 1 wherein the set of the sectors associated with the reservation zone include all of the sectors in a national network.
10. The method of claim 1 wherein using the reserved one of the connection identifiers in the first group to communicate with the first user comprises transferring the reserved one of the connection identifiers to the first user, receiving communications that include the reserved one of the connection identifiers from the first user, and providing the quality of service level to the first user in response to the reserved one of the connection identifiers being in the received communications.
11. A method of operating a wireless communication system that has a plurality of base stations, the method comprising:
allocating, by a reservation system, connection identifiers into at least a first group of the connection identifiers and a second group of the connection identifiers;
associating, by the reservation system, a set of the base stations with a reservation zone, associating the reservation zone with the first group of the connection identifiers, and associating the first group of the connection identifiers with a quality-of-service level;
in response to a first service request from a first user, determining, by the reservation system, that the first user has the quality-of-service level, and in response, reserving one of the connection identifiers in the first group for the first user and using the reserved one of the connection identifiers in the first group to communicate with the first user from all of the base stations associated with the reservation zone;
in response to a second service request from a second user, determining, by the reservation system, that the second user does not have the quality-of-service level, and in response, using different ones of the connection identifiers in the second group to communicate with the second user from each one of the base stations.
12. The method of claim 1 further comprising:
transferring, by the reservation system, the reserved one of the connection identifiers in the first group to the first user for use throughout the reservation zone; and
transferring, by the reservation system, the different ones of the connection identifiers in the second group to the second user as the second user moves between the base stations associated with the reservation zone.
13. The method of claim 1 wherein the connection identifiers comprise worldwide interoperability for microwave access unicast connection identifiers.
14. The method of claim 1 wherein the connection identifiers comprise worldwide interoperability for microwave access service flow identifiers.
15. The method of claim 1 further comprising determining, by the reservation system, that the first group of the connection identifiers has a surplus and that the second group of the connection identifiers has a shortage, and in response, re-allocating at least one of the connection identifiers in the first group to the second group.
16. The method of claim 1 further comprising determining, by the reservation system, that the second group of the connection identifiers has a surplus and that the first group of the connection identifiers has a shortage, and in response, re-allocating at least one of the connection identifiers in the second group to the first group.
17. The method of claim 1 wherein the set of the base stations associated with the reservation zone include all of the base stations served by an access service network gateway in a worldwide interoperability for microwave access system.
18. The method of claim 1 wherein the set of the base stations associated with the reservation zone include the current base station used by the first user and all of the base stations that are adjacent to the current base station.
19. The method of claim 1 wherein the set of the base stations associated with the reservation zone include all of the base stations in a national network.
20. The method of claim 1 wherein using the reserved one of the connection identifiers in the first group to communicate with the first user comprises transferring the reserved one of the connection identifiers to the first user, receiving communications that include the reserved one of the connection identifiers from the first user, and providing the quality of service level to the first user in response to the reserved one of the connection identifiers being in the received communications.
