Adaptive call admission control for use in a wireless communication system

A method for allocating bandwidth among connections between a base station and customer premise equipment (CPE) in a wireless communication system the method comprising:

• receiving a request for additional bandwidth from a requesting CPE;
• summing hard bandwidth commitments of the base station and CPEs associated with the base station;
• determining an air link line rate between the base station and associated CPEs;
• and
• allocating additional bandwidth to the requesting CPE if the air link line rate exceeds the hard bandwidth commitments, else determining if a second CPE has a lower priority than the requesting CPE and if it does, de-allocating bandwidth from the second CPE and allocating additional bandwidth to the requesting CPE.

A method for controlling connections between a base station and associated customer premise equipment (CPE) in a wireless communication system the method comprising:

• receiving a request for additional bandwidth from a requesting CPE;
• summing hard bandwidth commitments of the base station and CPEs associated with the base station;
• determining an air link line rate between the base station and associated CPEs;
• and
• allocating additional bandwidth to the requesting CPE if the air link line rate exceeds the hard bandwidth commitments, else maintaining the existing bandwidth allocation.

A method for allocating bandwidth among connections between a base station and customer premise equipment (CPE) in a wireless communication system the method comprising:

• receiving a request for additional bandwidth from a requesting CPE;
• summing bandwidth commitments of the base station;
• determining an amount of available bandwidth of the base station;
• and
• allocating additional bandwidth to the requesting CPE if the available bandwidth exceeds the bandwidth commitments, else determining if a second CPE has a lower preference than the requesting CPE and if it does, de-allocating bandwidth from the second CPE and allocating additional bandwidth to the requesting CPE.

A customer premise equipment (CPE) in a wireless communication system, the CPE comprising:

• a transmit module that transmits a request for additional bandwidth and a priority value to a base station where in the base station will allocate additional bandwidth to the CPE based on the request and priority value;
• a receive module that receives control signals from the base station;
• and
• a control module that adjusts a modulation scheme of the CPE based on the control signal from the base station.

A communication system that allocates bandwidth among existing connections between a base station and customer premise equipment (CPEs) the system comprising:

• a first CPE having a first modem that modulates data using a first current modulation scheme and a first initial modulation scheme different from the first current modulation scheme;
• a second CPE having a second modem that modulates data using a second current modulation scheme and a second initial modulation scheme;
• a base station having a third modem that transmits and receives data to and from the first and second CPEs;
• and
• a call admission control (CAC) module that determines whether to re-allocate bandwidth among the first and second CPEs based on bandwidth requests from the CPEs, bandwidth commitments between the base station and the CPEs, and available bandwidth between the base station and the CPEs.

A method for allocating bandwidth among connections between a base station and associated customer premise equipment (CPE) in a wireless communication system the method comprising:

• receiving an uplink that is modulated by a first CPE using a first modulation scheme;
• determining a quality for a channel parameter for the uplink;
• comparing the quality with a first modulation scheme threshold value;
• determining if the quality is less than the first modulation scheme threshold value, and if it is then determining if additional bandwidth is available to allocate to the CPE, wherein if additional bandwidth is available allocating it to the CPE, else replacing the first modulation scheme threshold value with a second modulation scheme threshold value.

A computer program product, comprising:

• computer-readable medium comprising computer instructions that when executed cause a computer to:
• receive a request for additional bandwidth from a CPE;
• sum hard bandwidth commitments of the base station and CPEs associated with the base station;
• determine an air link line rate between the base station and associate CPEs;
• and
• allocate additional bandwidth to the CPE if the air link line rate exceeds the hard bandwidth commitments, else denying the additional bandwidth.
