Patent ID: 7630378

Claim:
A method for improving quality of service QoS mechanisms in bandwidth allocation in a CDMA mobile communication system, comprising: during a PDP context activation, sending, from a subscriber end unit to a radio network controller in the mobile communication system a requested minimum bandwidth the subscriber end unit requires, comprising sending an RAB ASSIGNMENT REQUEST message including QoS parameters and information regarding a guaranteed bit rate, a minimum bit rate and a maximum bit rate that are available to the subscriber end unit, from an assigned network node to a network node radio network controller, wherein the minimum and maximum bit rates correspond to the signaled bandwidth, provided that sufficient bandwidth capacity is available; allocating, by the radio network controller in the mobile communication system, to the connection with the subscriber end unit, a bandwidth within the signaled bandwidth, if available; and handling, via the radio network controller, an assignment of a Radio Access Bearer RAB and of codes according to the signaled bandwidth, wherein the assignment of the RAB and signaled bandwidth takes place according to a number of rules, wherein the guaranteed bit rate is greater than the minimum bit rate and smaller than the maximum bit rate.
