Communication terminal with WLAN base station functionality or WLAN client functionality
View Patent ↗In one aspect a communication terminal comprising a first interface, a second interface is provided, and a connection unit. The first interface for connecting to a first network for the bidirectional transmission of information between the first interface and a central communication device, arranged in a first network. The second interface allows a link can be establishment with a radio network. The communication terminal is established as a base station for the radio network, when the connection unit is activated. The radio network is a WLAN.

a first interface effective for connecting to the first network and providing a bidirectional transfer of information between the first interface and the central communication device; and
a second interface effective for connecting to a dongle of a wireless communication network,
wherein the communication terminal is configured to be automatically set up as a base station of the wireless communication network when the dongle is connected to the second interface; and
wherein a connection is establishable between at least one device of the wireless communication network and the central communication device via the communication terminal when the dongle is connected to the second interface.
2. The communication terminal as claimed in claim 1 , wherein the first network is a fixed network.
3. The communication terminal as claimed in claim 2 , wherein the fixed network is an IP-oriented network or an ISDN network.
4. The communication terminal as claimed in claim 2 , wherein the second interface is a USB interface.
5. The communication terminal as claimed in claim 4 , wherein the dongle is a USB WLAN dongle.
6. The communication terminal as claimed in claim 2 , wherein the second interface is a PCMCIA interface.
7. The communication terminal as claimed in claim 6 , wherein the dongle is a PCMCIA WLAN plug-in card.
8. The communication terminal as claimed in claim 2 , wherein power is supplied via the first interface and the first network.
9. The communication terminal as claimed in claim 2 , further comprising a power supply connected to the communication terminal.
10. The communication terminal as claimed in claim 2 , wherein the communication terminal is a communication telephone configured to be directly connected to the central communication device.
11. The communication terminal as claimed in claim 2 , wherein the communication terminal is embodied as a mobile communication terminal configured to establish a connection to the central communication device via the wireless communication network when the dongle is activate or is embodied as a desktop terminal configured to establish a connection to the central communication device via the wireless communication network when the dongle is activated.
12. The communication terminal of claim 1 wherein the wireless communication network is a radio network or a WLAN network.
13. The communication terminal of claim 1 wherein the connection establishable between the wireless communication network and the central communication device via the communication terminal is a connection between a wireless communication terminal of the wireless communication network and the central communication device.
14. A method for establishing a connection between a central communication device and a wireless communication device via a communication terminal, the central communication device arranged in a first network, the wireless communication device configured to communicate via a wireless communication network, the method comprising:
providing a first interface of the communication terminal effective for connecting to the first network to permit a bidirectional transfer of information between the first interface and the central communication device;
providing a second interface of the communication terminal effective for communicating wirelessly to the wireless communication device;
activating the second interface so that the communication terminal is automatically set up as a base station of the wireless communication network; and
establishing a connection between the wireless communication device and the central communication device via the first and second interfaces when the second interface is active.
15. The method of claim 14 wherein the wireless communication network is a radio network or a WLAN network.
16. The method of claim 14 wherein the second interface is activated by attaching a dongle to the second interface of the communication terminal.
17. The method of claim 14 wherein the first network is an IP-oriented network, an ISDN network, or a fixed network.
18. The method of claim 14 wherein the second interface is activated after a dongle is attached to the second interface and wherein the connection between the wireless communication device and the central communication device is established after the wireless communication device is out of connection range to a wireless communication cell of a WLAN access point.
