Abstract
A method and arrangement for connecting an ad-hoc communication network (101) to a permanent communication network (102), e.g. to a cellular mobile communication network. The ad-hoc communication network is established between communication devices (103-106) and a gateway device (107) using a routing protocol that is run in the gateway device and in the communication devices. A protocol address that is associated in a communication device with a protocol data unit is determined on the basis of a control action given by a user of the communication device. In a gateway device, the protocol data unit is relayed to the permanent communication network if the protocol data unit is provided with a pre-determined protocol address. The user of the communication device can determine with the aid of the control action whether he is communicating only inside the ad-hoc communication network or via the permanent communication network.

39. An arrangement for connecting an ad-hoc communication network (101) to a permanent communication network (102), the arrangement comprising:
-
a communication device (103, 104, 105, 106, 303) that includes a processor unit (311) arranged to run a routing protocol for including the communication device into the ad-hoc communication network, a control interface (312) arranged to receive a pre-determined control action given by a user of the communication device, a circuitry arranged (313) to create a protocol data unit (315), and a transmitter (314) arranged to transmit the protocol data unit to the ad-hoc communication network, and a gateway device (107) that includes a processor unit (611) arranged to run the routing protocol for including the gateway device into the ad-hoc communication network, a receiver (612) arranged to receive the protocol data unit, and a transmitter (616) capable of relaying data carried by the protocol data unit to the permanent communication network, characterized in that the processor unit of the communication device is arranged to provide the protocol data unit with a predetermined protocol address as a response to the pre-determined control action, and otherwise, to provide the protocol data unit with another protocol address, and the processor unit of the gateway device is arranged to relay the data carried by the protocol data unit to the permanent communication network as a response to a situation in which the protocol data unit is provided with the pre-determined protocol address. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)

59. A method for connecting an ad-hoc communication network to a permanent communication network, the method comprising:
-
running (701, 801) a routing protocol in a communication device and in a gateway device for including the communication device and the gateway device into the ad-hoc communication network, creating (702, 802) a protocol data unit in the communication device, in the communication device, providing (704, 804) the protocol data unit with a pre-determined protocol address as a response to a pre-determined control action given by a user of the communication device (703, 803), and otherwise, providing (705, 805) the protocol data unit with another protocol address, and transmitting (706, 806) the protocol data unit from the communication device to the gateway device via the ad-hoc communication network, characterized in that the method further comprises relaying (708), in the gateway device, data carried by the protocol data unit to the permanent communication network as a response to a situation in which the protocol data unit is provided with the pre-determined protocol address (707). - View Dependent Claims (60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70)
