Integration of voice and data services provided to a mobile wireless device

A computer readable medium storing computer program instructions capable of execution on a computer system for controlling the operation of a telecommunication network node and for routing packet data over a data network to a wireless device in response to a data request from the wireless device, said computer program instructions defining the steps of:

• receiving a voice network address of the wireless device as part the of the data request, wherein said data request is sent via the voice network and wherein the voice network address is used to establish voice call connections with the wireless device;
• performing a database lookup to retrieve a data network address of said wireless device using said voice network address, wherein said data network address has been previously assigned to said mobile unit;
• and
• sending packet data corresponding to information that was requested by the wireless device, wherein the packet data is routed through said data network using said data network address without establishing a voice connection to the wireless device in response to the data request.

A telecommunications network node for providing information to a wireless device in response to information requests from the wireless device, comprising:

• a computer processor coupled to a data network and to a voice network;
• a memory connected to said computer processor for storing computer program instructions for execution on said computer processor, said computer program instructions defining the steps of:
• receiving an information request from the wireless device, the information request being sent over the voice network and including a voice network address for the wireless device;
• performing a database lookup to retrieve a data network address for the wireless device, wherein said data network address and the voice network address have been previously assigned to said wireless device;
• and
• sending packet data to the wireless device using the data network address to route the packet data, wherein the packet data comprises information provided in response to the information request from the wireless device without establishing a voice connection to the wireless device in response to the information request.

A method of providing requested information to a wireless device, the wireless device capable of communication with both voice networks and data networks via a wireless network connection, the wireless device having a voice network identifier that is used to establish communications via the voice network and a corresponding data network identifier that is used to establish communications via the data network, the method comprising:

• receiving a command from the wireless device via the voice network, the command including the voice network identifier;
• identifying the command as a request for information that is to be sent to the wireless device;
• correlating the voice network identifier to the corresponding data network identifier for the wireless device;
• obtaining the requested information;
• and
• sending the requested information to the wireless device via the data network using the data network identifier to route the information.
