Abstract

A system and method for using an IP client attached to the Public Internet, acting as a virtual mobile terminal such as a cell phone, to have full access to mobile telephony services offered by a mobile operator using a SIP2 Mobile gateway. The services include a mobile telephone number, capabilities of sending and receiving short messages and mobile intelligent services such as prepaid billing, number translation, and ring back tones.

Claims

1. A method to process a phone call between a user of an IP client and a called party attached to a mobile network, wherein said user of said IP client subscribes to mobile services from a mobile service provider, said method comprising:

intercepting an invite message from said IP client by a phone server, said phone server further performing the steps;

parsing said invite message;

sending said invite message to a registry, location and services database to check if said called party is registered;

sending said invite message to said called party if said called party is registered,

sending said invite message to a signaling conversion component if said called party is not registered, said signaling conversion component mapping said invite message to a ISUP message, said signaling conversion component further communicating said ISUP message with a service control and call control component, said service control part starting a new call state, sending said ISUP message to VLR/MSC and sending an INAP message to a SCP, and said call control part communicating with a media gateway control component attached to said VLR/MSC, said media gateway control component further sending an MGCP message to a media gateway component to connect IP traffic into a trunk group of said media gateway component.

2. A method to process a phone call between a user of an IP client and a called party attached to a mobile network, according to claim 1, wherein said method may be used for sending short messages and multimedia messages by using a IM to SMS relaying component that maps said short or said multimedia message into a MAP message and sends it to a message service center, attached to said VLR/MSC of said mobile network.

3. A method to process a phone call between a user of an IP client and a called party attached to a mobile network, according to claim 1, wherein said IP client is registered using the following steps:

sending an IP register message by said IP client to said phone server;

parsing said IP message by said phone server;

sending a radius request by said phone server to a registry database;

authenticating said IP client with said phone server if said IP client'"'"'s mobile phone number is found in said registry database;

sending an IP address of said IP client by an IP registry server to a location database if said IP client is authenticated;

adding said IP address and said mobile phone number of said IP client to said location database;

initiating a location update request by said phone server and sending said location update request to a mobility control component;

generating a MAP location update message by said mobility control component using said mobile phone number of said IP client and sending said MAP message to a VLR/MSC;

sending said MAP message by said VLR/MSC to a HLR;

storing location of said IP client by said HLR and responding to said location update message with services to which said mobile phone number of said IP client subscribes;

relaying of said services response by said VLR/MSC to said mobility control component;

forwarding said services response to said phone server if said mobility control component receives said services response;

sending a confirmation on said location update by said phone server to said registry database, and

storing said services response into a services database.
