Abstract
Abstract A system and method for facilitating a telecommunication subscriber connection using a domain name system is disclosed. The system, which is part of a DNS server, supports connection to a mobile terminal through a data network and includes multiple connections to external devices or systems, although one or more of the connections may be serviced by a single link. The connections link the system to the data network, to a home location register (“HLR”) associated with the terminal and to a mobile switch associated with the terminal. Upon initiation of a query to the DNS server through the PDN, the DNS server signals the HLR for the identification of the switch that is associated with the mobile terminal. The HLR returns an identifier for the switch and the DNS server then requests the switch to provide an address for the mobile terminal. The switch establishes a connection with the mobile terminal and provides a temporary address through a network interface system such as an interworking function. The switch then returns this new address to the DNS server.

A system for supporting connection to a mobile terminal through a data network, the mobile terminal not having a currently assigned address, the system comprising: a connection to the data network; a connection to a register associated with the mobile terminal; a connection to a switch associated with the mobile terminal; and if a query for signaling the register for the identification of the switch is received from the data network, requesting the switch to initiate a link with the mobile terminal and to provide, by an interworking function associated with the switch, an address for the mobile terminal, and forwarding the address to the data network, wherein the switch establishes a data path and a signaling path to the interworking function which terminates the signaling path with a protocol device associated with the mobile terminal and routes data to one of either a modem device or a protocol device suited for the data network, and wherein the data from the modem device is forwarded to a public switched telephone network via the switch and the data from the protocol device suited for the data network is forwarded to the data network.
Claim 2
Independent Claim
192 words
A system for supporting connection to a mobile terminal through a data network, the mobile terminal not having a currently assigned address, the system comprising: a connection to the data network; a connection to a register associated with the mobile terminal; a connection to a switch associated with the mobile terminal; and if a query for signaling the register for the identification of the switch is received from the data network, requesting the switch to initiate a link with the mobile terminal and to provide, by an interworking function associated with the switch, an address for the mobile terminal, and forwarding the address to the data network, wherein the switch establishes a data path and a signaling path to the interworking function which terminates the signaling path with a protocol device associated with the mobile terminal and routes data to one of either a modem device or a protocol device suited for the data network, and wherein the data from the modem device is forwarded to a public switched telephone network via the switch and the data from the protocol device suited for the data network is forwarded to the data network.
