System and method for providing packet data and voice services to mobile subscribers

For use in cooperation with an Internet Packet Data Network (IPDN) and an Advanced Intelligent Network (AIN) having an existing wireline switch, a system for providing Internet data and voice services to mobile subscribers at mobile terminals without using a mobile telephone switch, the system comprising:

• a Home Location Register (HLR) for storing and providing subscription information of said mobile terminals and keeping track of where said mobile terminals are registered in order to deliver Internet data and voice calls thereto;
• a plurality of Radio Port Controllers (RPCs) each having a corresponding serving area and provided in electrical communication with said wireline switch via ISDN signalling, each of said RPCs further having at least one Radio Port (RP) provided in electrical communication with an RPC for transmitting and receiving Internet data and voice calls to and from mobile terminals registered in said RPC serving area and means for performing handover between a target RPC and an RPC currently serving a mobile terminal by bridging a call made from the target RPC to the RPC currently serving the mobile terminal internally, wherein said wireline switch has no knowledge of said handover;
• an Internet Access Node in electrical communication with said wireline switch;
• a Home Agent in electrical communication with said Internet Access Node via said IPDN and operable with the RPCs for transmitting and receiving Internet data to and from said mobile terminals;
• and
• a Visitor Location Register/Directory Number Manager (VLD/DN-Mgr) in electrical communication with said wireline switch, said HLR, and said plurality of RPCs for managing call information about said mobile terminals registered in said RPC serving areas by assigning and deleting temporary routing Directory Numbers (DNs) for said calls.
