Abstract: A telecommunication network node which integrates the voice and data services provided to a wireless mobile unit. The network node receives a request for information along with a voice network identification of the mobile unit via the signaling portion of the voice network. The network node performs a database lookup to determine a data network address of the mobile unit. This data network address may be a permanent data network address or a temporary data network address. The network node sends the information request to a data network service provider, whereby the request may be enhanced with information added by the network node. Upon receipt of the requested information from the data network service provider, the network node forwards the information to the mobile unit via the data network using the data network address.
