Abstract: The invention relates to a transmission method in a communication system. In order to devise a mechanism for providing seamless connections in an efficient way, location-dependent parameter sets are utilized, each parameter set containing at least one parameter indicative of the location of a mobile node. A group of variables associated with the mobile node is monitored, the group containing at least one variable of which at least one is derived from said parameters. The current value of said at least one variable is compared with predetermined first criteria, and a multicast-based operation mode is selected when said at least one variable meets the predetermined first criteria. In the multicast-based operation mode, data destined for the mobile node is transmitted (1) to the current access point and (2) to a set of potential new access points prior to a handover. (FIG.

Abstract: The present invention is directed to a method for locating a mobile station, comprising the steps of using fixed transmitting stations for locating a target mobile station by transmitting a measurement signal from each fixed transmitting station to the mobile station, using a relay station which is adapted to receive the measurement signal from the corresponding fixed transmitting station and to forward the signal to the target mobile station, in case a direct transmission from one or more of the fixed transmitting stations is not available, and determining the distance between the target mobile station to the fixed transmitting stations and/or the relay stations on the basis of the measurement signal, and locating the position of the target mobile station on the basis of the determined distances. By this method, it is possible to locate a mobile station even if there is no direct connection via air to neighbouring base stations.

Abstract: According to the invention, better requests resulting in the load being under a first predetermined limit are admitted. If a bearer request would result in the load being over the first predetermined limit, the admission control entity tries to make room for the bearer request, i.e. release resources without degrading the quality of service (QoS) provided for the existing bearers. The admission control entity may perform this by adjusting power control parameters, handover control parameters, or both. If the admission control entity is able to make enough room for the new bearer or bearers, the request is admitted.

The security is provided by setting at least one of security parameters for a connection of a node to another node of the network.

Abstract: 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.

Abstract: A traffic and radio resource control in a wireless device with multiple operation modes is disclosed. For accomplishing an efficient use of physical and radio resources in terms of the required service level, a first set of radio transmission resources is selected for an assembled output data stream. A path is then searched for with respect to each destination node of the stream, each path leading from the wireless communication device to the destination node in question and fulfilling the service level requirement corresponding to that destination node. The transmission of the output data stream is then scheduled according to the current state of the wireless communication device, when a path is found for each of the destination nodes. The operation modes of the wireless communication device are controlled to maintain the required service level during the transmission.

Abstract: A method is provided for solving the mobility of a mobile trunk node (MTN) within an operated assisted mobile mesh local Ad-Hoc network. The method provides a reverse handover (RHO) when there exists another node within the local Ad-Hoc network, which is able to assume the logical role of a MTN. Before the first MTN performs the handover, existence of the other suitable MTN is determined. Where a suitable MTN is determined, the MTN functions are transferred to the new MTN before handover of the first MTN to a new cell of a cellular-based network. Upon transfer of the MTN functions to the new MTN, Ad-Hoc traffic is relayed to and from the local Ad-Hoc network via the new MTN. Enhanced tunneling is proposed to minimize network traffic delays during the handover. The reverse handover also enables the first MTN to preserve its original merely Ad-Hoc local network connection.

Abstract: A method and apparatus provide security services in an ad-hoc network. In order to provide security services, a set of user identities is transmitted from a first ad-hoc node to a second network external to the ad-hoc network. The set of user identities includes user identities related to at least one ad-hoc node. A first set of authentication parameters is generated in the external network. The first set of authentication parameters includes an authentication vector for each user identity included in the set of user identities and each authentication vector including a second set of authentication parameters. Some of the authentication parameters of the second set are transferred to the first ad-hoc node, whereby a third set of authentication parameters is received at the first ad-hoc node. The third set of authentication parameters is utilized at the first ad-hoc node for providing a security service in the ad-hoc network.

Abstract: A method for controlling transmission power in a radio system and in a WCDMA system network in particular for maximizing cell capacity. An acceptable transmission power margin and an optimum power level, which may change specifically for each connection and service class, are determined for the transmission power. Transmission power is adjusted using power control steps utilizing an incoming power control command and previous power control steps. The power control step size is adjusted as a sum of a fixed and a variable dynamic step size where the dynamic value is obtained on the basis of the measured value and the target value of the signal-to-noise ratio. Information on the network state can be obtained by comparing AC and LC data and the cell capacity can be maximized by controlling the amount of transmission power calculated by the mobile station before the final power transmission.
