Abstract

A system, method, and apparatus for transmitting a packet from a server to a wireless client, using direct digital calls, wherein the server initiates the call are presented. The server transmits a packet to addressed to an Internet Protocol (IP) address associated with the wireless client. The packet is received by a wireless application gateway which maintains a table correlating IP addresses with mobile services integrated services digital network (MSISDN) numbers or mobile identification numbers (MIN). The MSISDN/MIN number is then used to request routing information. In response to the request, a dynamic IP address and a traffic channel are allocated to the wireless client. The dynamic IP address is transmitted to the wireless application protocol gateway. Upon receiving the IP address, the wireless application protocol gateway transmits the digital data communication towards the IP address. The digital data communication is received by a serving mobile switching center which causes the digital data communication to be transmitted to the wireless client using the allocated traffic channel.

Dependent claims

A mobile telecommunications system, said mobile telecommunication system comprising:

a wireless application protocol gateway for receiving a digital data communication associated with an Internet Protocol address from an Internet server in a certain format and converting said certain format and said Internet Protocol address of said digital data communication to a wireless application protocol format associated with a mobile telecommunications system number of a wireless client, wherein said wireless application protocol gateway comprises:
a first memory for storing a plurality of static Internet Protocol addresses, said plurality of Internet Protocol addresses including said Internet Protocol address associated with said digital data communications;
a second memory for storing a plurality of mobile telecommunications system numbers, said plurality of mobile telecommunications system numbers including said mobile telecommunications system number associated with said wireless client, and wherein each of said mobile telecommunications system numbers is associated with a particular one of said plurality of Internet Protocol addresses;
and
a processor for selecting the mobile telecommunications system number based on the Internet Protocol address of said digital data communication, wherein said mobile telecommunications system number is associated with said Internet Protocol address;
a home location register for storing location information associated with the wireless client to which the digital data communication is addressed;
and
a signal link connecting the wireless application protocol gateway to the home location register, and wherein said home location register is queried by said wireless application protocol gateway over the signal link for said location information associated with said wireless client, the location information being used to route the wireless application protocol converted digital data communication to the wireless client.
