摘要： The invention is directed towards determining an access node (14, 16) for a terminal (18) in a network (10) having one or more access nodes capable of providing access to the terminal based on one or more access technologies. Access node is selected through determining whether at least one network parameter provided by a network node (12, 14, 16) is required as input for the access node selection for the terminal. If it is determined that the at least one network parameter is required as input, the network parameter is obtained and an access node possibly together with access type for the terminal is selected at least based on said network parameter.

摘要： The present invention relates to the technical field of dynamic spectrum access. Synchronization of quiet periods for spectrum sensing can significantly benefit sharing of available secondary access spectrum between two or more wireless communication systems in the same geographic region. The object of the present invention is to provide a methodology by which quiet periods can be synchronized in time between different secondary access wireless communication systems. Quiet Period Clients (QPC) of secondary access wireless communication systems are adapted to send requests to a Quiet Period Server (QPS) to obtain a quiet period rule set. The QPC receives from the QPS an answer specifying the quiet period rule set, and optional quiet period synchronization information. The systems perform their transmissions in accordance with the received rules.

摘要： A method and arrangement for making a handover decision in a multi-access communication network is disclosed. A first set of criteria is determined for when a handover between at least two access paths should be performed and a report is sent when at least one criterion of a first set of criteria is fulfilled. A second set of criteria is determined for when a handover between said at least two access paths should be performed and a report is sent when at least one criterion of said second set of criteria is fulfilled. One or more data sessions of at least one user terminal network are determined to be handed over based on the sent reports and a core network anchor and a terminal anchor are directed to execute a handover by re-routing said determined data sessions from one access path to an alternative access path.

摘要： This invention extends routing mechanisms that use link metrics for route selection so that: A link metric cross correlation vector is determined for all links, where each element in the vector corresponds to some other link, and reflects the change in the link metric value if a data flow would already use this other link. The invention further describes a specific embodiment where all cross-correlating links are adjacent to each other, i.e., they terminate or originate in a common node. A mechanism is described to create an extended routing graph. This extended graph permits the use of standard polynomial time algorithms that simultaneously construct the optimal route and find the optimal route metric (such as shortest-path algorithms) also for the adjacent link cross-correlating case.

摘要： A network node (110) and a method therein for managing radio, resources are disclosed. The radio resources are dedicated for beacon (121, 122) signaling, fey a first device; (131) and a second device (132), in conjunction with device-to-device, “D2D”, discovery. The first device: (131) is stationary and the second device (132) is non-stationary. The network node (110) selects (202) a first and a second set of radio resources out of the radio resources. The first and second sets are dedicated for beacon signaling by the first device (131) and the second device (132), respectively. The first set of radio resources Is non-overlapping with the second set of radio resources. Then the network node (110) schedules (203) a specific radio resource of the first set of radio resources to the first device (131). Next, the network node (110) sends (204) information about the scheduled specific radio resource to the first device (131). The network node (110) further sends (205) information about the second set of radio resources to the second device (132). In this manner, the second device (132) restricts Us radio resources usable for beacon signaling to the second set of radio resources.
