Patent number: 8572620Abstract: The invention relates to a method, device and system for management of resource in a communication network having a resource owner (RO) providing the resource and at least one resource user (RU) using the resource. According to the present invention a resource broker is introduced between the resource owner and the at least one resource user. Said broker is arranged to perform a management procedure for deciding whether to perform a allocation, keeping or release of resource. In order to take a decision a resource usage measure (TTL) is used. In accordance with the present invention said measure is updated when user's usage measure (Keep Alive, InterestMsg) informing about the expected usage of the resource by a resource user is obtained. The update is performed by means of a cumulative algorithm taking into account current and past values of the resource usage measure (TTL).Type: GrantFiled: August 21, 2004Date of Patent: October 29, 2013Assignee: Telefonaktiebolaget L M Ericsson (publ)Inventors: Frank Hundscheidt, Alexandru Hlibiciuc
