Abstract: In a radio system a network node is provided to be operatively connected to a set of radio base stations of the radio network and to retrieving a neighbor list from each radio base station in said set of radio base stations. Based on said list of neighbors it is determined if a pair of radio base stations lack a connection between them, and upon determining that a connection between two radio base stations is lacking a connection between said pair of radio base stations is set up.

Abstract: A method for use in a network node (210, 220) in a Wi-Fi network (200) for handling an access attempt by a wireless device (121) is provided. The wireless device (121) is also configured to operate in a wireless telecommunications network (100). The wireless telecommunications network (100) comprises a policy control node (350) comprising information associated with the wireless device (121) that is registered via the wireless telecommunications network (100). The network node receives the information associated with the wireless device (121) from the policy control node (350) in response to transmitting an authentication request comprising an identifier associated with the wireless device (121) to an authentication node (510, 520) based on an access attempt to the Wi-Fi network (200) by the wireless device (121). Then, the network node determines whether or not the access attempt by the wireless device (121) to the Wi-Fi network (200) is allowed at least partly based on the received information.

Abstract: A method, system, and apparatus enables lower priority (e.g., access response) messages to be transmitted instead of higher priority (e.g., paging) messages when the lower priority messages become too backlogged in an environment in which the two types of messages share a given capacity. In other words, when an overload situation is detected, the shared capacity is regulated by ensuring that the lower priority messages have at least some bandwidth. For example, if (i) the lower priority messages reach a predetermined number or (ii) a particular lower priority message has been waiting a predetermined period of time, then at least a portion of the higher priority messages are diverted (e.g., delayed or deleted). In one embodiment, the higher priority messages that are initially diverted are a lowest priority subset of the higher priority messages. In another embodiment, a highest priority subset of the lower priority messages are transmitted first as capacity is made available.

Abstract: A device for the separation of solid objects (9) from fluid flowing in a conduit tube (2) includes a housing that includes a tubular outer wall (3) and a tubular inner wall (4). Between these is delimited a collecting space (8). Concentrically relative to the inner wall (4) is provided a rotation-symmetrical central body (12) which at opposing ends cooperates with flow converting devices (15, 16), which transform incoming flow to a rotative motion and outgoing flow to an axial motion. In the inner wall (4) are recessed tangentially separated holes (20) of elongated shape, through which the scrap objects may pass and be collected in a collecting space (8). In the collecting space (8) a calm flow operation is obtained which guarantees that collected scrap objects are not carried away and returned to the main fluid flow through the separation device.

Abstract: The present invention is related to a method and arrangement in a radio communication system for performing a message transfer transaction in which at least one message is transferred in at least one frame from a first unit to a second unit. Properties of radio signals exchanged between the first unit and the second unit are measured (501). A mode of informing the first unit of frame receipt status at the second unit during the message transfer transaction is selected (502) based on the measured radio signal properties. The at least one frame is transferred (503) from the first unit to the second unit while the first unit is informed of the frame receipt status at the second unit in accordance with the selected mode of informing.

Abstract: The present invention provides a method and system for quickly deallocating packet traffic channels. According to exemplary embodiments of the present invention, the capability of performing point-to-multipoint communications is provided on the PTCH by defining a multicast address that all mobiles read. Through the use of a multicast address, a plurality of mobile stations can simultaneously be notified of the termination of PTCH services. As a result, the network can reallocate PTCH resources in a minimum amount of time.
