Telecommunications system and method enabling use of a general personal number in fixed and mobile networks and cordless access systems

Claim 1

A calling method comprising the steps of: initiating a call from at least one of a first telecommunications network and a cordless access system to a subscriber located in at least one of a second telecommunications network and a second cordless access system, including DECT; registering the subscriber in the second telecommunications network with a specific number that corresponds to a current access point in the at least one of a second telecommunications network and a second cordless access system; and connecting the call to the subscriber through a central network node, including the steps of, transmitting within the call a general personal number corresponding to the subscriber, connecting the call having the general personal number contained therein at the central network node, regardless of which type of telecommunication network the call emanates from or form of the call, converting in the central network node the received general personal number to the corresponding specific number that corresponds with the current access point, and executing a connection to the current access point, so that the connection is made independent of the at least one of the first telecommunications network and the cordless access system from which the call is initiated and independent of the at least one of the second telecommunications network and the cordless access system in which the subscriber is located, wherein said connecting step includes connecting the central network node to at least one of the first telecommunication network and the second telecommunications network without influencing a function of either respective network, a numbering scheme of either respective network, or a terminal in either respective network, said executing step includes realizing a direct communication between the central network node and at least one of a HLR of a GSM system and a HMTX of a NMT system.

Claim 14

A system using at least one of an existing telecommunications network and a cordless access system connected to said existing telecommunication network, comprising: means for initiating a call from a calling subscriber to the existing telecommunications network in which the calling subscriber is located, said means for initiating a call includes transmitting within the call a personal number corresponding to a called subscriber, said called subscriber being registered in a second telecommunications network; and a central networking node connected to the existing telecommunications network without influencing a function of the network, a numbering scheme of the network, and a terminal of the network, comprising, means for connecting the call with the central networking node, regardless of which type of telecommunication network the call emanates from or form of the call, means for receiving the personal number at the central network node, means for converting the personal number to a specific number corresponding to a current access point of the second telecommunications network, and means for executing a connection of the call to the current access point, said means for executing includes means for realizing a direct communication between the central network node and at least one of a HLR of a GSM system and a HMTX of a NMT system.

Claim 15

A system using at least one of an existing telecommunications network and a cordless access system connected to said existing telecommunication network, comprising: means for initiating a call from a calling subscriber to the existing telecommunications network in which the calling subscriber is located, said means for initiating a call includes transmitting within the call a personal number corresponding to a called subscriber, said called subscriber being registered in a second telecommunications network; and a central networking node connected to the existing telecommunications network without influencing a function of the network, a numbering scheme of the network, and a terminal of the network, comprising, means for connecting the call with the central networking node, regardless of which type of telecommunication network the call emanates from or form of the call, means for receiving the personal number at the central network node, means for converting the personal number to a specific number corresponding to a current access point of the second telecommunications network, and means for executing a connection of the call to the current access point, said means for executing includes means for realizing a direct communication between the central network node and at least one of a HLR of a GSM system and a HMTX of a NMT system.
