communicate with the RCC to request a radio resource,
communicate with the SDU to allocate a selector resource, and
perform at least one of subscriber registration, call setup, call release and call handoff.
2. The IP RAN of claim 1 comprising an interoperability system (IOS) signaling control connection part (SCCP) in the MCP coupled to the MCC.
3. The IP RAN of claim 2 , wherein the IOS and the SCCP are combined.
4. The IP RAN of claim 3 , wherein the SCCP is adapted to communicate with a call agent.
5. The IP RAN of claim 1 comprising a packet control function (PCF) in the MCP coupled to the SDU.
6. The IP RAN of claim 5 comprising a first operation, administration, and maintenance (OA&M) module coupled to the PCF.
7. The IP RAN of claim 6 , wherein the first OA&M module is adapted to communicate with a basestation manager.
8. The IP RAN of claim 6 comprising a configuration management (CM) block in the OA&M module, the CM block coupled to the PCF and to the CEC.
9. The IP RAN of claim 8 comprising a transceiver module coupled to a second OA&M module.
10. The IP RAN of claim 9 , wherein the transceiver module is adapted to communicate with an IF chip, a transceiver, and a power amplifier.
11. The IP RAN of claim 5 comprising a call agent simulator (CA_SIM) in the MCP coupled to the IOS SCCP.
12. The IP RAN of claim 5 , wherein the PCF is adapted to communicate with a packet data serving node.
13. The IP RAN of claim 1 , wherein the SDU is adapted to communicate with a gateway.
14. A system, comprising:
