Abstract

A mobile station of a mobile radio network includes speech exchange arrangements and data exchange arrangements. Selector arrangements select the speech exchange arrangements by default and change to the data exchange arrangements when necessary. The data exchange arrangements comprise a set of components for sorting, analyzing and processing the data and the commands exchanged between two terminal equipments so that a mobile terminal equipment capable of exchanging data according to a first standard (the V.24 standard+modem protocol, for example) can communicate with another, remote terminal equipment via a digital network using a second standard (V.110+GSM network, for example).

Claims

1. Mobile station of a digital mobile radio network for exchanging speech signals and data signals comprising:

connection means to a first data processing terminal equipment for bidirectional exchange of data according to a first data exchange standard using a single transfer channel carrying data and commands simultaneously,

first means for sending data to and receiving data from a second data processing terminal equipment via said mobile radio network according to a second data exchange standard using a data transfer channel and command transfer channel,

second means for sending speech signals to and receiving speech signals from a remote terminal via said mobile radio network according to a third data exchange standard, and

means for monitoring a bidirectional call between said mobile station and remote station;

wherein said monitoring means comprises;

means for selection either said first or said second sending and receiving means according to whether said call carries data or a speech signal, and

interface means for converting data signals between said first and second data exchange standards;

wherein said interface, in the direction from the first standard towards the second standard, comprises;

means for separating data and commands delivered by said first terminal equipment,

first transcoding means for transcoding said data delivered by said separating means from said first standard to said second standard and delivering data to be transmitted on said data transfer channel,

first sorting means for sorting said commands into two sets of commands, a first set of commands to be transmitted to said second terminal equipment and a second set of commands to be executed by said mobile station,

means for interpreting commands of said second set of commands and delivering a second set of interpreted commands, and

first means for mapping commands of said first set of commands and delivering commands to be transmitted on said command transfer channel;

wherein said interface means, in the direction from the second standard towards the first standard, comprises;

second means for sorting command received on said command transfer channel and delivering a third set of commands to be transmitted to said first terminal equipment and a fourth set of commands to be executed by said mobile station,

second means for mapping commands of said third set of commands and delivering commands to be transmitted to said first terminal equipment,

second means for transcoding data received on said data transfer channel from said second standard to said first standard and delivering data to be transmitted to said first terminal equipment, and

means for grouping said commands and said data to be transmitted to said first terminal equipment in order to transmit them over said single transfer channel; and

wherein said interface means further comprises means for supervising said call from said second set of interpreted commands and a full set of commands and handling initialization, monitoring of said call.

2. Mobile station according to claim 1 wherein said supervising means generate command to be transmitted on said single transfer channel or said command transfer channel according to said second set of interpreted commands, said fourth set of commands and external information.

3. Mobile station according to claim 1 wherein said selecting means select by default said second speech signal sending and receiving means and said first data sending and receiving means are selected on reception of a call request sent by said first or said second terminal equipment.

4. Mobile station according to claim 1 wherein said selecting means send a specific instruction to enable/disable certain modules of said mobile station when said first data sending and receiving means are selected.

5. Mobile station according to claim 4 wherein said specific enabling/disabling instruction disables at least some keys of a keypad.

6. Mobile station according to claim 1 wherein said first data standard is the V.24 standard associated with a modem protocol.

7. Mobile station according to claim 1 wherein said second data standard is the V.110 standard.

8. Mobile station according to claim 1 wherein said digital mobile radio network is a GSM network.

9. Mobile station according to claim 1 comprising means for selecting between at least two different data bit rates for exchanges of data to said first data standard.

10. Mobile station according to claim 9 comprising means for adapting the format of the date exchanged according to said second data standard depending on said bit rate selected.

11. Mobile station according to claim 1 comprising means for controlling the flows sent or received by said mobile station.

12. Mobile station according to claim 1 wherein said first sorting means deliver a fifth set of commands for configuring said mobile station to suit the requirements of said first terminal equipment.
