Voice over Internet protocol (VoIP) call admission and call regulation in a wireless network

A method for providing wireless data packet access for wireless Voice over Internet Protocol (VoIP) communications in a network element of a wireless network, the method comprising:

• receiving a data packet and generating a first time stamp for the data packet if the first time stamp was not received with the data packet;
• transmitting the received data packet to a mobile terminal;
• receiving an acknowledgement (ACK) from the mobile terminal;
• generating a second time stamp upon reception of the ACK from the mobile terminal if the ACK does not include the second time stamp;
• determining a packet delay from the first and second time stamps;
• producing the packet delay to at least one filter to produce an average delay metric;
• and
• based upon the average delay metric produced by the at least one filter, determining whether to drop on-going calls.

An access point for performing call admission and call control in a wireless network, comprising:

• transceiver circuitry for receiving and for transmitting data packets that include data messages and signaling messages;
• at least one buffer for storing received data packets that carry data messages that can not be transmitted immediately;
• at least one buffer for storing received data packets that carry signaling messages that can not be transmitted immediately;
• time stamp logic for generating time stamps and for calculating a delay between the reception of a data packet and an acknowledgement of the data packet;
• at least one filter for producing a plurality of average delay metrics;
• sorting logic for routing the calculated delay to the at least one filter of a plurality of filters;
• delay logic for generating a call admission policy based on the plurality of average delay metrics;
• and
• scheduling logic for prioritizing the buffered data packets based on a subscriber class of service.
