Abstract
A method and system for managing radio resources in a time-slotted wireless communication system is based on the quality of service (QoS) information of a user. A plurality of time slots of a radio resource are sorted into a plurality of different categories, such as high QoS time slots, high capacity time slots, and balanced time slots. Each category is associated with a different level of QoS. QoS information with respect to a user is obtained in response to a radio resource request received from the user. The user is associated with a particular category of time slots based on the QoS information of the user.

(a) means for sorting a plurality of time slots of a radio resource over which a communication is transmitted into a plurality of different categories, each category being associated with a different level of quality of service (QoS), each time slot being assigned one of a plurality of QoS designations based upon the QoS of a user, wherein the QoS designations include high QoS time slots, high capacity time slots, and balanced time slots, each user is classified into one of three subscriber classes including a high QoS service subscriber, a high capacity service subscriber and a balanced service subscriber; (b) means for obtaining QoS information with respect to users in response to radio resource requests received from the users; (c) means for assigning high QoS time slots to users classified as high QoS service subscribers based on the obtained QoS information; (d) means for assigning balanced time slots to users classified as balanced service subscribers based on the obtained QoS information; (e) means for assigning high capacity time slots to users classified as high capacity service subscribers based on the obtained QoS information; (f) means for adjusting the available number of at least one of the high QoS time slots, the balanced time slots and the high capacity time slots if congestion occurs; (g) means for constantly monitoring a state of traffic; (h) means for dynamically adjusting the number of time slots assigned to each time slot designation if traffic congestion occurs or the data rate for a particular time slot designation changes; (i) means for freeing high capacity time slots and adjusting QoS requirements to avoid traffic congestion if a handover is initiated and there are not enough resources in a desired target cell to which the handover is directed; and (j) means for adjusting delay and jitter for scheduling the data packets based on time slot designation if data packet scheduling is required. - View Dependent Claims (45, 46, 47, 48, 49)
