Patent ID: 8526960

Claim:
A first node for use in a mobile telecommunication network that includes a second node configured to execute a master-proxy-process and a third node configured to execute a slave-process, wherein the first node is configured to execute a master-process, and wherein execution of the master-process and the slave-process realizes a system function associated with a mobility of the third node, and wherein the execution of the master-process realizes a control function associated with the system function, wherein the control function relates to management of an active set for the third node, characterized in that, while the master-process of the first node has responsibility for managing the active set, the first node is adapted to issue commands related to managing the active set to the third node through the second node and the first node is further adapted to temporarily delegate the responsibility for managing the active set to a master-proxy-process implemented in the second node, and wherein the master-process is adapted to receive heartbeat messages from the master-proxy-process while the master-proxy-process has responsibility for managing the active set in order to obtain information that the master-proxy-process is functioning.
