摘要： The invention provides methods method for access selection in a Multi-Access Network offering a plurality of Access Technologies (AT). The device may comprises a Multi Access Management entity (MAM) and a plurality of Generic Link Layer Entities (GLL) associated to a plurality of Accesses (A) according to said plurality of Access Technologies (AT). The access selection comprises an Access determination and an Access configuration. In a first step a Generic Link Layer Entity (GLL) determines one or more Generic Performance Metrics (GPM) corresponding to one or more configurations of the Access (A). The Generic Link Layer Entity (GLL) sends the determined one or more Generic Performance Metrics (GPM) corresponding to one or more configurations of the access (A) to the Multi Access Management entity (MAM). The Multi Access Management entity (MAM) determines from received Generic Performance Metrics (GPM), which Access (A) offers a configuration (GPM), which is suited for an application/bearer requirements. Then, said Multi Access Management entity (MAM) sends the determined configuration to the Generic Link Layer Entity (GLL) associated to the determined Access (A). The determined Generic Link Layer Entity (GLL) configures the Access (A) based on the determined configuration received from the Multi Access Management entity (MAM). Furthermore, the invention relates to corresponding devices, modules and software.

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 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： 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 arid 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.

摘要： The invention relates to a method for allocating a common radio resource for simultaneous transmission of data streams in multiple pairs of communication nodes in a multi-node wireless network. The invention also relates to a method of assessing radio resource isolation in a multi-node wireless network. The inventive methods include transmission (44) of at least a first and a second test probe message on a common radio test resource. Receipt of the intended test probe messages are verified (45), whereupon radio resource isolation may be determined and a common radio resource allocated (46) for transmission in the tested communication node pairs. The invention also relates to a communication node and a control node wherein the inventive methods are applied.

摘要： In a radio system where wireless nodes are in contact, the wireless nodes are enabled to exchange information with adjacent nodes. In addition, distant nodes out of range for direct communication can be communicated with by forwarding data over multiple hops. The wireless nodes are configured to perform sensing of at least one radio resource. A node can be adapted to combine the sensing measurement data into a sensing result, such as an estimate of the probability of whether the resource is free or not. The sensing performed in a node is distributed to at least one other wireless node. Each wireless node can, therefore, access sensing information from at least one other wireless node located in the vicinity of the wireless node. Based on the collective information from at least one other node, a wireless node can make an improved decision if a particular radio resource is free to use or not.
