Abstract

A system for routing calls between a switching unit and a mobile unit. The system comprises a wireless adjunct and a radio transmit point. The wireless adjunct, in communication with the switching unit and a packet based network, is operable to receive voice data from the switching unit and place the voice data, in packetized form, on the packet based network. The radio transmit point, in communication with the packet based network and the mobile unit, is operable to receive the voice data, in packetized form, from the packet based network and provide the voice data to the mobile unit.

Claims

1. A radio transmit point for interfacing a mobile unit to a packet based network for transmission of communication data, comprising:

a network interface for communicating with the packet based network and for receiving communication data from the packet based network;

a first base station component, in communication with the network interface and the mobile unit, operable to manage call processing and provide communication data from the network interface to the mobile unit over an air interface.

2. The radio transmit point of claim 1, wherein the first base station component is operable to manage a call setup.

3. The radio transmit point of claim 1, wherein the radio transmit point is further operable to report fault management data over the packet based network.

4. The radio transmit point of claim 1, wherein the first base station component is operable to communicate over the air interface using a first communication standard selected from one of a TDMA standard, a CDMA standard, a GSM standard, a UMTS standard, and a CDMA2000 standard.

5. The radio transmit point of claim 4, further comprising a second base station component operable to communicate over a second air interfacing utilizing a second communications standard different from the first communications standard.

6. A method of interfacing a mobile unit to a packet based network for transmission of packetized communication data, comprising:

receiving a call setup request from the packet based network;

setting up a call with the mobile unit;

receiving the packetized communication data from the packet based network; and

providing the packetized communication data to the mobile unit over an air interface.

7. The method of claim 6, further comprising, prior to setting up a call with the mobile unit:

registering the mobile unit;

paging the mobile unit; and

receiving a response from the mobile unit.

8. The method of claim 7, further comprising halting the paging of the mobile unit upon receipt of a command from the packet based network.

9. The method of claim 6, wherein the packetized communication data comprises at least voice data.

10. A method of routing calls from a mobile unit to a destination location, comprising:

registering the mobile unit;

responding to a call setup request from the mobile unit;

receiving, over an air interface, communication data from the mobile unit;

converting the communication data to packetized communication data; and

providing the packetized communication data to a packet based network for communication to the destination location.
