Method for providing VoIP services for wireless terminals
First Claim
1. A device for processing voice over internet protocol data packets for wireless terminals, comprising:
- an internet protocol/ethernet interface for establishing a real-time transport protocol path with a voice over internet protocol phone;
a voice over internet protocol media gateway interposed between an air interface that establishes a voice path wirelessly with a mobile station and the internet protocol/ethernet interface for media conversion and transportation;
a voice over internet protocol signaling gateway for controlling voice over internet protocol call processing; and
,a call control in communication with the voice over internet protocol media gateway and the voice over internet protocol signaling gateway for controlling call processing for wireless terminals and coordinating with voice over internet protocol call processing.

Abstract
The present invention relates to a system and method for wireless telecommunication in a packet-based network comprising a Software Radio Port (SRP) which functions as a radio base station and a VoIP gateway to interconnect the wireless network with the VoIP packet network. Together with a Network Server Platform (NSP) and VoIP call-server, the SRP combines mobile call processing signaling with the VoIP call signaling to establish calls between the mobile and VoIP device or between mobiles. The SRP establishes the voice path to the mobile station over the air and the RTP media path to a party over a packet network for a call. These two paths are interconnected at the SRP so that an end-to-end voice path is established.

12. A method of providing a path between a voice over internet protocol device in a network and a mobile station, comprising:
-
tuning the mobile station to a digital traffic channel to establish a voice path wirelessly via a software radio port; engaging a voice over internet protocol call-server to set up a voice over internet protocol call; generating a ringback tone to the mobile station; establishing a real-time transport protocol media path for exchange of real-time transport protocol data packets via said the software radio port; and interconnecting the voice path and the real-time transport protocol media path over a packet network via the software radio port. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method of providing a path between a voice over internet protocol device in a packet network and a mobile station, comprising:
-
processing a call connection request at a voice over internet protocol call-server; initiating mobile call set-up at a network server platform; tuning the mobile station to a digital traffic channel to establish a first path wirelessly via a software radio port; establishing a real-time transport protocol media path for exchange of real-time transport protocol data packets via the software radio port; and interconnecting the first path and the real-time transport protocol media path over the packet network via the software radio port.
