Abstract: Methods, network entities (215a-216c), and user equipment (UE) (210a-210b) are described for use in a communication system (200) including a wireless local area network (WLAN) (204a-204b) and a telecommunications network including a radio access network (202a-202c) and a core network part. A network entity (215b) receives a WLAN access message from a UE (210a). The WLAN access message includes an indication of the UE status with the telecommunication network. The network entity (215b) detects the indication of UE status and determines from the indication whether to allow the UE access to the WLAN (204b). When the WLAN (204b) is integrated with the telecommunications network, the network entity (215b) sends a query to the telecommunication network (e.g. the RAN (202a-202c) or core network part) for a decision based on the UE status with the telecommunication network. The indication may include data representative of RAN or core network accessibility information (e.g.

Abstract: The present invention controls the association of a station to a wireless local area network, WLAN. In particular it enables an entity in a WLAN to control when a station requests association with the WLAN to reduce the number of requests that the entity has to process. The method involves an entity of the WLAN transmitting a message including a condition which has to be fulfilled before the station can transmit a request to associate with the WLAN.

Abstract: The invention provides a method of operating an entity in a wireless local area network, WLAN. In the method, upon determining that a device has been denied an association with or disassociated from the WLAN, the entity causes a WLAN identifier associated with the device to be stored in a database, an entry in the database indicating that the entity should not associate with the STA associated with the WLAN identifier, the WLAN identifier being stored in association with a condition such that when the condition is met the corresponding WLAN identifier is removed from the database.

This topology information can be used in allowing the base station to most efficiently set up a communication with another base station.

Abstract: A method and an arrangement for transmitting reference signals in a radio frame in a cellular communication system comprising at least one network node having a measurement bandwidth ?, which is more narrow than a full downlink bandwidth ? of said network node. Subframes only carrying reference signals, which are to be transmitted from said network node may be transmitted over a temporarily reduced transmission bandwidth ?, which is at least equally wide as the measurement bandwidth Y provided by the network node, and more narrow than the full downlink bandwidth ? of the network node. The use of a reduced transmission bandwidth leads to that less reference signals are transmitted, and thereby transmission power will be saved.

Abstract: A technique for determining a correlation among events occurring in one or more network elements is provided. The correlation among the events results from a propagation of a root event through communication entities of the one or more network elements. In a method implementation the technique comprises the step of receiving a plurality of event messages from one or more network elements, wherein an event message pertaining to an event reported by a particular network element signals an occurrence context, the occurrence context comprising one or more context identifiers describing an internal communication state of the communication entity in which the event occurred at the time when the event occurred. In another step, a set of correlated events linked by identical context identifiers is determined. Based on the set of correlated events, the root event may be identified.

Abstract: Radio coverage in areas with normally poor radio conditions can be improved using distributed relay nodes to relay communications between the base station and user terminal. The distributed relay node comprises two main functional components interconnected by a local area network. The functional components of the relay node comprise a terminal part that appears to the serving base station as another user terminal, and a base station part that appears to the user terminal as a base station. The terminal part and base station part of the relay node can be remotely located and interconnected by an existing local area network based IP protocols. A packet delivery mechanism transfers data packets between the terminal part and base station part of the relay node in a manner that is transparent to the rest of the mobile communication network.
