Abstract
A method and system to provide GSM subscribers roaming into CDMA or TDMA networks, and CDMA or TDMA subscribers roaming into GSM networks, with basic call delivery wireless services as long as the roamers can pay the bill with their valid credit card, and to do so independently of and as a bypass of GSM Memorandum of Understandings for cellular/PCS services. This is achieved by integrating the proper pieces of wireless and wireline networks and secure communications, using IP networks and protocols as an alternative to the existing telephony-based approach.
Claims64
A method to provide billing resolution and basic wireless call delivery service for a roaming user's mobile device, between a home wireless network supporting a home air interface technology and a visited wireless network supporting a visited air interface technology, the method comprising the steps of:
- providing a home wireless network coupled to an existing Public Switched Telephony Network (PSTN) and a signalling network comprising at least one of an existing Global Systems for Mobile communication (GSM) Mobile Application Part (MAP) signalling network and an existing American National Standards Institute (ANSI-41) signalling network;
- redirecting call delivery service for a user's mobile device from the home wireless network to a voice and data service provider's network that is independent of the home wireless network, the signalling network, and the visited wireless network;
- receiving redirection information from the voice and data service provider's network and storing the received redirection information within the user's mobile device;
- relocating the user's mobile device to a roaming area served by a visited wireless network;
- passing the redirection information and billing resolution information from the user's mobile device to the visited wireless network;
- associating the user's mobile device with the visited wireless network;
- providing a first bypass network separate and distinct from the existing signalling network and the existing PSTN network;
- communicating the association of the user's mobile device with the visited wireless network via the first bypass network to the voice and data service provider's network;
- providing a second bypass network separate and distinct from the existing signalling network and the existing PSTN network;
- delivering at least one redirected call responsive to the voice and data service provider's network via the second bypass network and via the visited wireless network to the user's mobile device;
- and
- resolving billing for the wireless call delivery service responsive to the billing resolution information.
A system to provide billing resolution and basic wireless call delivery service for a roaming user's mobile device, between a home wireless network and a visited wireless network, the system comprising:
- a user's mobile device,
- a home wireless network, coupled to both an existing Public Switched Telephony Network (PSTN) and a signalling network comprising at least one of an existing Global Systems for Mobile communication (GSM) Mobile Application Part (MAP) signalling network and an existing American National Standards Institute (ANSI-41) signalling network;
- a voice and data service provider's network;
- redirecting call delivery means to redirect call delivery service from the home wireless network to the voice and data service provider's network;
- a visited wireless network;
- and
- bypass network means coupling the visited wireless network and the voice and data service provider's network, wherein the bypass network means is separate and distinct from the existing signalling network and the existing PSTN network;
- wherein the user's mobile device comprises at least:
- home wireless network operating means to provide for operating within the home wireless network;
- visited wireless network operating means to provide for operating within the visited wireless network;
- and
- storage means for storing redirection information;
- and
- wherein the visited wireless network comprises association means for associating the user's mobile device with the visited wireless network and billing resolution means for resolving billing for the wireless call delivery service.
