System and method for establishing mobile station-to-mobile station packet data calls between mobile stations in different wireless networks
First Claim
1. A method of establishing a packet data session from an originating mobile station (MS) operating in a first wireless network to a terminating mobile station (MS) operating in a second wireless network, the method comprising the steps of:
- receiving in an originating base station (BS) of the first wireless network a packet data connection request transmitted by the originating MS;
transmitting a phone number of the terminating MS from the originating BS to an originating mobile switching center (MSC) of the first wireless network;
transmitting a first message containing the phone number of the terminating MS from the originating MSC to a terminating mobile switching center (MSC) of the second wireless network via a switched telephone network; and
transmitting a second message from the terminating MSC to the terminating MS via a terminating base station of the second wireless network, the second message informing the terminating MS that a packet data session with the originating mobile station is being established.

Abstract
A method of establishing a packet data session from an originating mobile station (MS) to a terminating mobile station (MS). The method comprises the steps of: i) receiving in an originating base station (BS) of a first wireless network a packet data connection request transmitted by the originating MS; ii) transmitting the terminating MS phone number from the originating BS to an originating mobile switching center (MSC) of the first wireless network; iii) transmitting a first message containing the terminating MS phone number from the originating MSC to a terminating mobile switching center (MSC) of a second wireless network via a switched telephone network; and iv) transmitting a second message from the terminating MSC to the terminating MS via a terminating base station of the second wireless network, the second message informing the terminating MS that a packet data session with the originating mobile station is being established.

- 11. For use in a telecommunication system, a server capable of establishing in an IP network coupled to the server a packet data session between an originating mobile station (MS) operating in a first wireless network and a terminating mobile station (MS) operating in a second wireless network, wherein the server receives a mobile IP address of the originating MS from an originating base station (BS) of the first wireless network via a first packet data bearer connection established between the originating BS and the IP network.

19. For use in a server coupled to an Internet protocol (IP) network, a method of establishing in the IP network a packet data session between an originating mobile station (MS) operating in a first wireless network and a terminating mobile station (MS) operating in a second wireless network, the method comprising the steps of
receiving a mobile IP address of the originating MS from an originating base station (BS) of the first wireless network via a first packet data bearer connection established between the originating BS and the IP network; -
receiving the phone number of the terminating MS from the originating BS via the first packet data bearer connection;
receiving a mobile IP address of the terminating MS from a terminating base station (BS) of the second wireless network via a second packet data bearer connection established between the terminating BS and the IP network; and
receiving the phone number of the terminating MS from the terminating BS via the second packet data bearer connection. - View Dependent Claims (20, 21, 22)
