1. A method, comprising maintaining, at a communication terminal, a list of channels useable for communication, wherein the maintaining comprises updating the list of channels from a network node in case an update criterion is fulfilled, wherein said update criterion comprises an expiry timer indicating when the list of channels is valid, and wherein the updating comprises pulling, from the network node, the updated list of channels, obtaining, at the communication terminal, information on usability of a currently used channel, and switching, at the communication terminal, to one of the channels of the updated list of channels if the currently used channel becomes unusable; wherein prior to a threshold of the expiry timer an incremental update of the list is pulled from the network node, and following the threshold of the expiry timer a complete update of the list is pulled from the network node. |
