Abstract

A teleservice server in a wireless network provides an interface between a mobile station and an Internet protocol network thereby facilitating data transfers between these elements. The server translates datagrams from the IP network into a format suitable for transmission over a wireless network that provides voice communication capabilities. The server also translates data messages received from the mobile station over the wireless network into a format suitable for appropriate transmission in the IP network.

Claims

1. A method of locating a mobile station registered on one of a wireless packet data network and a wireless communication network, comprising:

receiving, at a device, a request to transfer Internet Protocol (IP) data from an application to the mobile station, the device capable of being coupled to the wireless packet data network and the wireless communication network;

querying, from the device, the wireless packet data network to locate the mobile station;

querying, from the device, the wireless communication network to locate the mobile station; and

locating the mobile station on at least one of the wireless packet data network and the wireless communication network before transferring the IP data to the mobile station.

2. The method of claim 1, wherein the wireless communication network is a network operating under a Time Division Multiple Access (TDMA) protocol.

3. The method of claim 1, wherein the wireless communication network is a network operating under a Code Division Multiple Access (CDMA) protocol.

4. The method of claim 1, wherein the wireless packet data network is a network operating under the Cellular Digital Packet Data (CDPD) protocol.

5. An enhanced server, comprising:

a message handler;

a wireless Internet Protocol (IP) handler;

a proxy; and

a dual messenger that, in response to receiving an IP data transfer notification request addressed to a mobile station'"'"'s IP address, determines if the mobile station is registered on a first wireless network having a first access protocol, and if the mobile station is not registered on the first wireless network, the dual messenger;

associating the mobile station IP address to the mobile station identifier; and

transmitting a notification request, identified by the associated mobile station identifier, to the message handler.

6. The enhanced server of claim 5, wherein the proxy forms an interface to an IP network and requests notification information from the dual messenger to obtain an identity of an application on the IP network that transmitted the IP data transfer notification request.

7. The enhanced server of claim 5, wherein the proxy receives data from an application on the IP network that transmitted the IP data transfer notification request and transfers the data to the mobile station via one of the message handler and the wireless IP handler.

8. A machine-readable medium having stored thereon a plurality of executable instructions, the plurality of instructions comprising instructions to:

receive, at a device, a request to transfer Internet Protocol (IP) data from an application to a mobile station, the device capable of being coupled to a wireless packet data network and a wireless communication network;

query, from the device, the wireless packet data network to locate the mobile station;

query, from the device, the wireless communication network to locate the mobile station; and

locate the mobile station on at least one of the wireless packet data network and the wireless communication network before transferring the IP data to the mobile station.
