Abstract: A method and arrangement for exchanging service and RAN information. In a communication network a service providing element is enabled to adapt delivery of a service based on RAN-related parameters. The communication network comprises a RAN (Radio Access Network) node, a core network node, and the service providing element. The RAN node obtains a RAN-related parameter and sends the RAN-related parameter to the service providing element via the core network node. The core network node receives the RAN-related parameter from the RAN node, re-structures the RAN-related parameter into a data structure readable by the service providing element, and sends the re-structured RAN-related parameter to the service providing element. The service providing element is configured to receive the RAN-related parameter, and adapt a service delivery parameter based on the RAN-related parameter.

Abstract: In a radio access network (14) comprising a serving radio network control node (261) and a drift radio network control node (262), a determination is first made that a target cell controlled by the drift radio network control node should be prepared for handover with respect to a user equipment unit (30). The target cell is neighbored by a set of neighboring cells, the set of neighboring cells including a first subset of neighboring cells and a second subset of neighboring cells, a handover involving the user equipment unit being permitted for a cell of the first subset but not for a cell of the second subset. In accordance with the determination, a message including a filtered list of cells is sent to the user equipment unit, the filtered list of cells including the first subset but not the second subset. The filtered list of cells can comprise, for example, a list of cells for whose frequencies the user equipment unit is to perform measurements.

Abstract: The invention concerns a method for determining whether to grant access of a user equipment (UE) to a radio access network in a present position of the user equipment (UE) within a communications system. The communications system comprises a control node (N1, N2) handling services for the user equipment (UE) and an access node (AN1, AN2) controlling the access network. The method is initiated by receiving a request for service processing for the user equipment (UE) in the control node (N1, N2) with an identification of the user equipment (UE). A subscriber group information is determined for the user equipment (UE) according to the identification of the user equipment and sent to the access node (AN1, AN2). Furthermore, an area access information according to the present location of the user equipment (UE) is determined in the access node (AN1, AN2).

Abstract: A base station synchronized Time Division Multiple Access (TDMA) System with a discontinuous control channel carrier is disclosed. Control channels are planned in a time reuse, overlaying the ordinary frequency reuse. Different base stations are allocated different timeslots for control channel transmissions. The control channels are allocated timeslots in a slot hopping fashion, such that transmissions from different base stations are detected by only monitoring one timeslot. Thus, MAHO measurements are possible on all neighbors, and no traffic allocation will continuously coincide with control channel transmissions from certain base stations.

Abstract: A packet data communication system uses an USF (Uplink State Flag) transmitted on the downlink and interleaved with downlink data, to schedule traffic on the uplink for one or several mobile users utilizing the same physical channel. The USF indication is made variable and defined in the control signaling at setup of a packet transmission. An USF indicates to a mobile that one or several consecutive radio blocks is reserved for uplink transmission from a specific mobile. The mobile does not have to receive the USF during the remaining period defined by the number of radio blocks scheduled. The solution is especially advantageous in combination with adaptive antennas when all radio blocks on the downlink transmissions do not have to be broadcast to all users on a certain channel.

Abstract: In a telecommunications network wherein a location area contains GSM cells having adjacent or neighboring UTMS cells, a dedicated procedure is employed to download information about a UTMS cell to a mobile station. After entering the location area, the mobile is notified of the presence of the UTMS cell. In response to the notice, the mobile is operated to acquire specified information about the UTMS cell from the network, such as frequency and scrambling code combinations, radio access bearer configuration, and information pertaining to intersystem cell selection.

Abstract: The invention relates to a method and apparatus for channel hopping between mobile stations (MS1-MS3) and a base station (BS1) in a radio communications system. A channel allocation means (211) within the base station (BS1) generates channel hopping sequences that are transmitted via a control channel (SACCH) to hopping sequence lists (204-206) in the mobile stations (MS1-MS3). The hopping sequences are also transmitted to corresponding hopping sequence lists (201-203) in the base station (BS1). A channel hopping sequence is divided into a number of sequence intervals (Ti) corresponding to the time between two adjacent channel hops within a channel hopping sequence. In the channel allocation means (211) the attenuation (&dgr;) of the connections (F1-F3) and the interference (I(channel,t)) of the channels are continuously being observed within each sequence interval (Ti).
