Abstract

A mobile-terminal simulator of a wireless telecommunications network includes a control module, a protocol simulator, and a baseband-modem module, coupled to the protocol simulator. The simulator is provided with a baseband interface for coupling in communication the baseband-modem module with a radio base station of a wireless telecommunications system with a low-frequency connection.

Claims

1. A mobile-terminal simulator of a wireless telecommunications network, comprising:

a control module;

a protocol simulator; and

a baseband-modem module, coupled to the protocol simulator;

characterized in that it comprises a baseband interface for communicably coupling the baseband-modem module with a radio base station of a wireless telecommunications system by a low-frequency connection.

2. The simulator according to claim 1, wherein the baseband interface is directly connectable to a baseband processor module of the radio base station.

3. The simulator according to claim 1, wherein the baseband interface is connectable to a baseband processor module of the radio base station through an internal interface of the radio base station.

4. The simulator according to claim 1, comprising a plurality of baseband interfaces for communicably coupling the baseband-modem module with respective radio base stations by low-frequency connections.

5. The simulator according to claim 1, wherein the baseband-modem module comprises an SDR platform.

6. The simulator according to claim 5, wherein the baseband-modem module is programmable.

7. The simulator according to claim 1, wherein the protocol simulator is configured to implement at least one instance of a protocol stack, corresponding to a telecommunications standard (ST1, ST2, ST3) usable by a mobile terminal of the wireless telecommunications system (1).

8. The simulator according to claim 7, wherein the protocol simulator is configured to implement a plurality of instances of the protocol stack.

9. The simulator according to claim 7, wherein the protocol simulator is configured to implement at least one instance of each of a plurality of protocol stacks, corresponding to respective telecommunications standards (ST1, ST2, ST3) usable by mobile terminals of the wireless telecommunications system.

10. The simulator according to claim 1, wherein the low-frequency connection is a baseband connection.

11. The simulator according to claim 1, wherein the low-frequency connection is a connection in an intermediate-frequency band between baseband and the radio frequencies.

12. The simulator according to claim 1, comprising a control module, coupled to the protocol simulator and to the baseband-modem module for selecting one of a plurality of operating modes, in order to submit to verification at least one portion of a wireless telecommunications system.

13. A telecommunications system comprising at least one radio base station and a mobile-terminal simulator of a wireless telecommunications network according to claim 1, connected to the radio base station.

14. The system according to claim 13, wherein the radio base station comprises a baseband processor module, an RF module and an internal interface for connecting the baseband processor module and the RF module by a low-frequency connection.

15. The system according to claim 14, wherein the baseband interface is directly coupled to the baseband processor module.

16. The system according to claim 14, wherein the baseband interface is coupled to the baseband processor module through the internal interface.
