SYSTEM, METHOD AND COMPUTER ACCESSIBLE MEDIUM FOR DETERMINING ACTION TIME IN A COMMUNICATION NETWORK
Publication number: 20090290554Abstract: Exemplary embodiments of system, method and computer accessible medium are provided for determining an action time in a communication network is described. For example, it is possible to estimate, in a target network arrangement, a value for an action time, with the value for the action time corresponding to the value for a handover time interval related to the target network node. The handover time interval can be a time interval starting substantially at the time when a first signal is received by a serving network node, which includes information about the value for the action time. For example, the handover time interval can have a duration during which the target network node is prepared to receive a handing over user equipment and the first signal. Further, the first signal can include information about the value for the action time, and such signal may be transmitted from a target network node to a serving network node.Type: ApplicationFiled: May 13, 2008Publication date: November 26, 2009Applicant: Nokia Siemens Networks OyInventors: Sami Siltala, Roman Pichna, Sandro Grech -
