Abstract
A communication terminal, comprising: first transceiver means for transmitting to and receiving from at least one communication terminal directly; second transceiver means for transmitting to and receiving from at least one communication terminal via a communications network; and selecting means for selecting the transceiver means in order to communicate with the at least one communication terminal.
Claims26
An apparatus, comprising:
- a first transceiver configured to transmit to and receive from at least one further apparatus directly;
- a second transceiver configured to transmit to and receive from at least one further apparatus via a cellular telecommunications network;
- a memory, said memory comprising a list identifying at least one further apparatus;
- a scanner configured to determine whether the listed at least one further apparatus is contactable via the first transceiver;
- a determining unit configured to determine if the listed at least one further communications terminal is configured to communicate using the first transceiver with at least one other communications terminal for which said second transceiver has been selected;
- and
- a selector configured to select the first or second transceiver in order to communicate with the listed at least one further apparatus, wherein the selector is configured to select the first or second transceiver in dependence on the scanner determining whether the listed at least one further apparatus is directly contactable via said first transceiver and configured to select the first transceiver configured to communicate directly to the listed at least one further communications terminal if the listed at least one further communications terminal is contactable via said first transceiver.
4 more elements
A method, comprising:
- choosing a list, the list comprising a list of identification values which can be used to contact a user operating at least one further communication terminal;
- detecting if any further communication terminal is directly contactable via a first transceiver;
- identifying if the listed at least one communications terminal is detected;
- determining if the listed at least one further communications terminal is configured to communicate using the first transceiver with at least one other communications terminal for which said second transceiver has been selected;
- selecting either a first transceiver for communicating directly to the listed at least one further communications terminal, or a second transceiver for communicating to the listed at least one further communications terminal via a communications network in dependence on the result of said identifying of detection;
- and
- selecting the first transceiver configured to communicate directly to the listed at least one further communications terminal if the listed at least one further communications terminal is contactable via said first transceiver.

An apparatus, comprising:
- first transceiver means for transmitting to and receiving from at least one further apparatus directly;
- second transceiver means for transmitting to and receiving from at least one further apparatus via a cellular telecommunications network;
- memory means for storing a list identifying at least one further apparatus;
- scanning means for determining whether the listed at least one further apparatus is contactable via the first transceiver means;
- determining means for determining if the listed at least one further communications terminal is configured to communicate using the first transceiver means with at least one other communications terminal for which said second transceiver means has been selected;
- and
- selecting means for selecting the first or second transceiver means in order to communicate with the listed at least one further apparatus, wherein the selecting means selects the first or second transceiver means in dependence on the scanning means determining whether the listed at least one further apparatus is contactable via said first transceiver means, and for selecting the first transceiver configured to communicate directly to the listed at least one further communications terminal if the listed at least one further communications terminal is contactable via said first transceiver means.
