Abstract

The invention relates to a process and a device for forwarding non-speech-bound information between a mobile communications network and any other communications network. To allow data packets data to be sent, regardless of its receiver address, to the involved communications network, the transmission route for the forwarding of the information is established as a function of the identification code of the data packet one logical transmission channel is assigned to each identification code, and each logical transmission channel is bound to exactly one physical transmission channel. For this purpose, an identification code is assigned to each incoming logical transmission channel. The logical transmission channels from the mobile communications network then are permanently connected to selected outgoing physical transmission channels to different communications networks. At least one logical transmission channel coming from the mobile communications network can be assigned to each outgoing physical transmission channel which is connected to a communications network.

Claims

1. A process for forwarding a data packet including non-speech-bound information between a mobile communications network and another communications network, wherein the data packet comprises an identification code indicating a service associated therewith, a receiver address, and the non-speech bound information, comprising the steps of:

assigning a specific service having a specific identification code to each one of a plurality of logical transmission channels connected to the mobile communications network;

connecting each one of the plurality of logical transmission channels to one of a plurality of physical transmission channels that is connected to a communications network with a service center associated with the specific service assigned to the each one of the plurality of logical transmission channels; and

establishing a transmission route for the forwarding of the data packet by selecting a selected logical transmission channel from one of the plurality of logical transmission channels in response to the identification code of the data packet thereby ensuring that the data packet is forwarded to a relevant communications network.

2. A multiplex device for forwarding a data packet including non-speech bound information between a mobile communications network and one of first and second other communications networks, wherein said data packet comprises an identification code, a receiver address, and the non-speech-bound information, the multiplex device comprising:

means for receiving a plurality of logical transmission channels connected to the mobile communications network, each said plurality of logical transmission channels having a specific identification code;

means for receiving first and second physical transmission channels respectively connected to the first and second other communications networks, the first other communications network comprising a first service center associated with a first identification code and the second other communications network comprising a second service center associated with a second identification code;

said first physical transmission channel being connectable with said second physical transmission channel and each of said plurality of logical transmission channels being connectable to one of said first and second physical transmission channels; and

multiplex means for connecting a selected one of the plurality of logical transmission channels to the first physical transmission channel if the specific identification code of the selected logical transmission channel is a first identification code and connecting the selected logical transmission channel to the second physical transmission channel if the specific identification code of the selected logical transmission channel is a second identification code thereby ensuring that the data packet forwarded on the selected one of the plurality of logical transmission channels is forwarded to a relevant one of said first and second other communications networks.

3. A multiplex device for forwarding a data packet including non-speech-bound information between a mobile communications network and one of first and second other communications networks, wherein said data packet comprises an identification code, a receiver address, and the non-speech-bound information, the multiplex device comprising:

a first input connection receiving a plurality of logical transmission channels connected to the mobile communications network, each said plurality of logical transmission channels having a specific identification code;

a second input connection receiving a first physical transmission channel connected to the first other communications network and a third input connection receiving a second physical transmission channel connected to the second other communications network, the first other communications network comprising a first service center associated with a first identification code and the second other communications network comprising a second service center associated with a second identification code;

said first physical transmission channel being connectable with said second physical transmission channel and each of said plurality of logical transmission channels being connectable to one of said first and second physical transmission channels; and

a multiplexer for connecting a selected one of the plurality of logical transmission channels to one of the first physical transmission channel and the second physical transmission channel in response to the specific identification code of the selected logical transmission channel and thereby ensuring that the data packet forwarded on said selected one of the plurality of logical transmission channels is forwarded to a relevant one of said first and second other communications networks.
