System and method for call admission for a mobile communication system
First Claim
1. A method of establishing a call for a Mobile Station (MS) according to the Quality of Service (QoS) of the call in a Base Transceiver Station (BTS) communicable with the MS in a service system where the MS, the BTS, and a Base Station Controller (BSC) are connected over a selected network, the method comprising the steps of:
- calculating a remaining available bandwidth;
determining whether the remaining available bandwidth can support a data rate required to guarantee the QoS of the call;
admitting the call if the data rate is supported;
and transmitting a call accept response signal to the BSC.

Abstract
A QoS-based call admission system and method for a mobile communication system. To establish a call for a mobile station according to the QoS of the call, upon request of setup of a call requiring a QoS guarantee, a base transceiver station determines whether a channel element is available. In the presence of an available channel element, the base transceiver station determines whether a remaining bandwidth can support a data rate required to guarantee the QoS. If the data rate is supported, the base transceiver station assigns the channel element and connects its intra switch to a base station controller. Then the base transceiver station transmits a call accept response signal to the base station controller.

19. A method of establishing a call for an Mobile Station (MS) according to the QoS Quality of Service (QoS) of the call in a Base Station Controller (BSC) in a service system having a profile server for storing the QoS profile information of the MS, where the MS, a Base Transceiver Station (BST) communicable with the MS, and the BSC are connected over a selected network, the method comprising the steps of:
-
r requesting the user profile information of the MS containing a QoS parameter to the profile server upon receipt of a call setup request message including a QoS parameter;
determining whether radio resources are available within the BSC if the user profile information includes the QoS parameter;
determining whether a remaining available bandwidth of the network connected to the BTS can support a minimum data rata required based on the QoS requirements of the call if the radio resources are available;
assigning the bandwidth and the radio resources; and
transmitting a call establishment request signal to the BTS, if the bandwidth can support the minimum data rate. - View Dependent Claims (20, 21, 22, 23, 24, 25)
