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.
