A wireless access gateway provides a telecommunications link between a packet switched network and a base transceiver station (BTS), the BTS enabling wireless communication with mobile stations in a wireless coverage area. A session manager controls sessions through the packet switched network, and a mobility server performs mobility management for mobile stations being served by wireless access gateways. A wireless access gateway includes a packet agent, a coding agent, a radio frequency (RF) manager, and a signaling control agent. The packet agent packetizes frames from the BTS into packets and depacketizes packets into frames for the BTS. The coding agent transcodes content contained in packets from a first format to a second format. The RF manager performs RF management of the BTS. The signaling control agent sends queries to and receives responses from the session manager to control the operation of the wireless access gateway.

What is claimed is: 1. A wireless access gateway for providing a telecommunications link between a base transceiver station (BTS) and a packet switched network, said BTS providing a wireless coverage area for wireless telecommunication with at least one mobile station, said wireless access gateway

What is claimed is: 1. A wireless access gateway for providing a telecommunications link between a base transceiver station (BTS) and a packet switched network, said BTS providing a wireless coverage area for wireless telecommunication with at least one mobile station, said wireless access gateway comprising: a packet agent in communication with said BTS and with said packet network, said packet agent packetizing frames from said BTS into packets, said packet agent depacketizing packets into frames for said BTS; a coding agent in packet communication with said packet agent, said coding agent transcoding content contained in packets from a first format to a second format; a radio frequency (RF) manager in packet communication with said packet agent, said RF manager performing RF management of said BTS; and a signaling control agent in packet communication with said packet agent, said signaling control agent controlling said packet agent. 2. The wireless access gateway of claim 1, wherein said coding agent transcodes content from a time division multiplexed (TDM) format to a vocoder format. 3. The wireless access gateway of claim 2, wherein said vocoder format is a code excited linear predictive (CELP) vocoder format. 4. The wireless access gateway of claim 2, wherein said vocoder format is a relaxed code excited linear predictive (RCELP) vocoder format. 5. The wireless access gateway of claim 4, wherein said vocoder format is an enhanced variable rate coder (EVRC) format. 6. The wireless access gateway of claim 1, wherein said RF manager performs wireless physical layer functions for said BTS. 7. The wireless access gateway of claim 1, wherein said signaling control agent is in packet communication with a session manager. 8. The wireless access gateway of claim 7, wherein said signaling control agent controls said packet agent in response to instructions from said session manager. 9. A method for using a first wireless access gateway to originate a call from a mobile station via a packet switched network, said first wireless access gateway including a packet agent and a signaling control agent, said method comprising the steps of: receiving, over an air interface, a call origination request from said mobile station; a packet agent packetizing said call origination request to provide at least one call origination packet; said packet agent transmitting said at least one call origination packet to said signaling control agent; said packet agent receiving at least one instruction packet from said signaling control agent, said at least one instruction packet instructing said packet agent to transmit packets containing content from said mobile station to a destination address in said packet switched network. 10. The method of claim 9, further comprising the step of: said signaling control agent transmitting, via said packet switched network, a first query message to a session manager. 11. The method of claim 10, further comprising the step of: said signaling control agent receiving, via said packet switched network, a first response message from said session manager. 12. The method of claim 11, wherein said first response message includes said destination address. 13. The method of claim 12, further comprising the steps of: said session manager transmitting, via said packet switched network, a second query message to an application server; and said session manager receiving, via said packet switched network, a second response message from said application server. 14. The method of claim 12, wherein said destination address corresponds to a trunk gateway, said trunk gateway being connected to a circuit switched network, said method further comprising the step of: said session manager sending, via said packet switched network, an instruction message to said trunk gateway. 15. The method of claim 14, further comprising the step of: said session manager signaling, via a signaling gateway, to set up a circuit switched communication link through said circuit switched network from said trunk gateway. 16. The method of claim 12, further comprising the step of: said session manager sending, via said packet switched network, a third query message to a mobility server; and said session manager receiving, via said packet switched network, a third response message from said mobility server, wherein said destination address corresponds to a second wireless access gateway. 17. A method for setting up a call to a mobile station via a circuit switched network and a packet switched network, said mobile station operating in a wireless coverage area served by a wireless access gateway, said wireless access gateway including a packet agent, a coding agent, and a signaling control agent, said method comprising the steps of: a session manager receiving, via a signaling gateway, a request from said circuit switched network to terminate a call to said mobile station; said session manager sending, via said packet switched network, a first instruction message to a trunk gateway, said trunk gateway being connected to said circuit switched network, said first instruction message instructing said trunk gateway to transmit packets containing content from said circuit switched network to a destination address in said packet switched network, said destination address corresponding to said coding agent. 18. The method of claim 17, further comprising the step of: said session manager sending a second instruction message to said signaling control agent, said second instruction message instructing said signaling control agent to control said packet agent to receive packets from said coding agent. 19. The method of claim 18, further comprising the steps of: said session manager sending, via said packet switched network, a first query message to a mobility server; and said session manager receiving, via said packet switched network, a first response message from said mobility server. 20. The method of claim 19, wherein said first response message includes said destination address. 21. The method of claim 19, further comprising the steps of: said session manager sending, via said packet switched network, a second query message to an application server; and said session manager receiving, via said packet switched network, a second response message from said application server.
