Abstract

The invention relates to a method for supporting a data exchange between terminal equipment and a mobile communication network via a mobile terminal. The method comprises at the mobile terminal receiving from the terminal equipment a request to establish a connection to the mobile communication network for exchanging data and forwarding this request to the mobile communication network. The method further comprises in case a failure occurs concerning the requested connection and an indication of a cause of the failure is received at the mobile terminal from the mobile communication network, forwarding the indication to the terminal equipment. The invention relates equally to a corresponding mobile terminal, to a corresponding terminal equipment, to a corresponding system and to a corresponding software program product.

Claims

1. A method for supporting a data exchange between terminal equipment and a mobile communication network via a mobile terminal, said method comprising at said mobile terminal:

receiving from said terminal equipment a request to establish a connection to said mobile communication network for exchanging data;

forwarding said request to said mobile communication network; and

in case a failure occurs concerning said requested connection and an indication of a cause of said failure is received from said mobile communication network, forwarding said indication to said terminal equipment.

2. The method according to claim 1, wherein said failure is a failure resulting in a rejection of said request to said mobile communication network to establish a connection, said indication being an indication of a cause of said rejection.

3. The method according to claim 1, wherein said failure is a failure resulting in a release of a connection established between said mobile terminal and said mobile communication network upon said request to establish a connection, said indication being an indication of a cause of said release.

4. The method according to claim 1, further comprising at said terminal equipment receiving said indication of a cause of a failure from said mobile terminal and presenting a corresponding information to a user of said terminal equipment.

5. The method according to claim 1, further comprising at said terminal equipment receiving said indication of a cause of a failure from said mobile terminal and storing said indication for further use.

6. The method according to claim 1, wherein said terminal equipment is connected to said mobile terminal by a point-to-point protocol connection and wherein said mobile terminal forwards said indication of a cause of a failure in a data field of a link control protocol packet.

7. A mobile terminal comprising:

a transceiver enabling an exchange of signals with a mobile communication network;

an interface enabling an exchange of signals with other devices; and

a processing component for receiving from terminal equipment via said interface a request to establish a connection to a mobile communication network for exchanging data, for forwarding said request to a mobile communication network via said transceiver, and in case a failure occurs concerning said connection and an indication of a cause of said failure is received from said mobile communication network, for forwarding said indication to said terminal equipment.

8. Terminal equipment comprising:

an interface enabling an exchange of signals with other devices; and

a processing component for requesting a mobile terminal via said interface to establish a connection to a mobile communication network, for receiving from a mobile terminal an indication of a cause of a failure concerning a requested connection and for processing a received indication of a cause of a failure.

9. Terminal equipment according to claim 8, further comprising a user interface, wherein said processing component is enabled to process a received indication of a cause of a failure by presenting a corresponding information to a user via said user interface.

10. Terminal equipment according to claim 8, further comprising a storing component, wherein said processing component is enabled to process a received indication of a cause of a failure by storing said received indication in said storing component for a later evaluation.

11. A system comprising a mobile communication network, a mobile terminal and terminal equipment,

said mobile terminal including:

a transceiver enabling an exchange of signals with said mobile communication network;

an interface enabling an exchange of signals with said terminal equipment; and

a processing component for receiving from terminal equipment via said interface a request to establish a connection to a mobile communication network for exchanging data, for forwarding said request to a mobile communication network via said transceiver, and in case a failure occurs concerning said connection and an indication of a cause of said failure is received from said mobile communication network, for forwarding said indication to said terminal equipment, and

said terminal equipment including;

an interface enabling an exchange of signals with said mobile terminal; and

a processing component for requesting a mobile terminal via said interface to establish a connection to a mobile communication network, for receiving from a mobile terminal an indication of a cause of a failure concerning a requested connection and for processing a received indication of a cause of a failure.

12. A software program product in which a software code for supporting a data exchange between terminal equipment and a mobile communication network via a mobile terminal is stored, said software code realizing the following steps when running in a processing component of a mobile terminal:

receiving from a mobile communication network an indication of a cause of a failure concerning a connection which has been requested by terminal equipment via said mobile terminal; and

forwarding said indication to said terminal equipment.
