摘要： In a multi-access system, an access selection principle is achieved by selecting a signal strength threshold level based on a determined load level (ULOCAL) in a first access network. A new user in an area commonly covered by more than one access network attempts to allocate to the first access network if an experienced signal strength exceeds the signal strength threshold level. Communication utility can preferably be maximised or at least be taken into account by using suitable load level dependencies. By increasing the threshold when the load level approaches the capacity limit, a completely filled first access network is avoided. This gives an opportunity to let particularly well-suited users still have access to the first access network. At the same time, since the preferred access is decided before the actual access attempt, control signalling can be significantly reduced, even at very high traffic loads.

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 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： 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： In a radio system where wireless nodes are in contact, the wireless nodes are enabled to exchange information with adjacent nodes. In addition, in one embodiment distant nodes out of range for direct communication can be communicated with by forwarding data over multiple hops. When a user, in particular a primary user, is detected by a node, a spectrum access blocking message is sent, to other nodes in the vicinity of the node thereby enabling blocking of the radio resource in a geographical area in which the other usage is detected. This means that the radio resource is blocked in that area from being accessed by other users than the primary user. The blocking message can be distributed in any suitable manner and can be tailored for the application at hand.
摘要翻译：在无线节点接触的无线电系统中，无线节点能够与相邻节点交换信息。另外，在一个实施例中，用于直接通信的远程节点可以通过在多跳上转发数据来传送。当用户特别是主用户被节点检测到时，向该节点附近的其他节点发送频谱接入阻塞消息，从而能够阻止另一个使用的地理区域中的无线电资源检测到。这意味着该区域的无线电资源被其他用户访问而不是主用户阻止。阻塞消息可以以任何合适的方式分发，并且可以针对手头的应用进行定制。
