Patent ID: 7630294

Claim:
A method for operating a terminal at a plurality of communication nodes, wherein the communication nodes and the terminal are arranged in a communication network, the method comprising: registering between the terminal and a first communication node by a first address to operate the terminal at the first communication node; establishing a logical connection between the terminal and the first communication node after the registration; storing the first address in the terminal for the purpose of registration; monitoring the accessibility of the first communication node; creating a status information item relating to the accessibility if the first communication node is inaccessible; setting up a logical connection between the terminal and a second communication node; operating the terminal at the second communication node; wherein the second communication node is selected from one of the plurality of nodes in the communication network, each of the plurality of communication nodes having a respective address; storing in the terminal a list having the addresses of the plurality of communication nodes; processing the list to establish a relative ranking for the plurality of communication nodes based on a respective level of communication services provided by each respective one of the plurality of nodes in the communication network, wherein the setting up of the logical connection between the terminal and the second communication is based on the established relative ranking for the plurality of communication nodes.
