Patent number: 7822023Abstract: The present invention is concerned with a method and a system for improving the quality of service in wireless networks and in particular in dynamically changing mobile ad hoc networks. The method of routing data packets through a network depending on priority information, which is based on the bandwidth requirements of each packet and the distance to the destination. To achieve a particular quality of service, a priority indicator is used to forward each packet at each node in the network. The priority indicator being determined based on a pre-determined relation between the distance and bandwidth information.Type: GrantFiled: April 14, 2003Date of Patent: October 26, 2010Assignee: Nokia CorporationInventors: Keijo Lahetkangas, Kai Mustonen

Patent number: 7649872Abstract: An architectural solution in which standalone ad-hoc network cells are used as an extension of the backbone infrastructure in terms of network architecture or/and its service capabilities is provided. These Ad-Hoc networks will integrate to the Internet via cellular and other access networks. This integration brings new possibilities to network operators and ISP's. In its extended architecture, it is envisaged that the mobility issues are handled by utilizing the IP mobility capabilities, taking into account the mobile mesh Ad-Hoc specific requirements. A trunk node is elected from among nodes within a service area of an Ad-Hoc domain that underlies an access domain. The trunk node acts as a gateway between the nodes within the Ad-Hoc domain and a backbone access network. The election can be performed by the trunk node itself or by a radio resource management entity.Type: GrantFiled: February 3, 2005Date of Patent: January 19, 2010Assignee: Nokia CorporationInventors: Siamak Naghian, Tapio Lindstrom, Tero Karkkainen, Jarmo Makinen, Keijo Lahetkangas, Kai Mustonen

Patent number: 7573904Abstract: A fast and secure ad hoc communication system is established between terminals with the aid of a network. Terminals equipped with a non-cellular interface may establish a high data rate peer-to-peer or multi-hop ad hoc connection with the support of a cellular network. The cellular network may provide signaling for user authentication, peer identification, key distribution for a secure non-cellular connection set-up, radio resources management messages, routing assistance information, as well as charging and billing for the service. A non-cellular link may be used for fast and secure ad hoc communication between the terminals. Signaling may be transported either over a non-cellular access network or, using dual-mode terminals, over the cellular RAN. A combination of the signaling transports is also possible.Type: GrantFiled: January 14, 2005Date of Patent: August 11, 2009Assignee: Nokia CorporationInventors: Roman Pichna, Keijo Lähetkangas, Kai Mustonen

Patent number: 7433681Abstract: The invention relates to a method, server and device arrangement for transmitting high-class multimedia messages of a mass event. When this method is utilized, the data transfer capacity of the cell of a cellular network serving the participants of the mass event need not be increased so that it would correspond to the capacity of the multimedia messages to be transmitted. In a method according to the invention, the cell that serves the mass event mainly transmits only text messages by which the multimedia messages to be sent from a multimedia server to some other terminal devices are defined.Type: GrantFiled: June 14, 2004Date of Patent: October 7, 2008Assignee: Nokia CorporationInventors: Markku Rytivaara, Mika Mustonen, Kai Ojala, Keijo Lähetkangas, Kai Mustonen
