Abstract: In a mobile station for use in a cellular radio system, the mobile station is adapted to increase radio measurements relating to the currently best cell at times when the user is preparing to set up a call in order to increase the likelihood that a mobile station is camping in the correct cell when setting up a call. This is obtained by adding a third mode to the already existing idle and active modes. The additional mode provides for an increased amount of idle mode measurements compared to the conventional idle mode.

Abstract: In a cellular radio system a message is transmitted in the uplink from a mobile station running an application to the cellular radio system informing the radio system of the status of the application thereby enabling the operator of the radio system to collect such data for use in optimizing the planning of the radio system or as an input parameter when detecting and trouble shooting problems in the radio system network.

Abstract: A sending user unit (400) provides data, intended to multiple receiving user units (410-430), to a communications server (100). The server (100) identifies a set of at least two receiving user units (410-412; 420-424) that participate in the session and are associated with a same cell (15; 25). The set of user units (410-412; 420-424) are identified based on session identifiers (144) and cell identifiers (146) stored in an associated database (140). The data from the sending user unit (400) is then simultaneously transmitted to the receiving user units (410-412; 420-424) in a point-to multipoint manner using a same dedicated channel specific for the cell (15, 25) in which the user units (410-412; 420-424) of set are present. The invention is in particular applicable to Push to talk over cellular (PoC) and other group-based data communications services.

Abstract: Expert system for evaluating diversity antenna installations. Antenna elements 11a. 11b have the respective coverage areas 32a and 32b. Due to an antenna mismatch the diversity is degraded or even lost for reception from mobile stations 13, 33 especially far from the antenna. By measuring the received signal strength. RXLEV, difference from the mobile stations in the respective branches of the diversity antenna the mismatch could be evaluated and corrected. By dividing the coverage areas into several zones with different distance to the antenna the result is enhanced.

Abstract: The present invention relates to a unit and a method for handling a data object that is to be transmitted over a link (39, 40, 41, 42), said data object being divided into at one least data unit. According to the invention the data unit that is in turn to be transmitted over the link (39, 40, 41, 42) should be handled differently depending on where a buffer fill level in a buffer (33, 34, 35, 36, 37, 38) preceding the link (39, 40, 41, 42) is in relation to at least one buffer threshold (51, 52, 53, 54, 55, 56, 57, 58, 59) in order to minimise end-to-end delay.

Abstract: A method is described herein that enables data traffic to be routed seamlessly to a mobile station which is located in a Second Generation/Third Generation (2G/3G) network and a Wireless Local Area Network (WLAN). In one embodiment of the present invention, the mobile station (MS) receives a signal (e.g., System Information (SI) signal) from a base station system (BSS) which informs the MS that it should check for the presence of one or more WLANs. The MS then scans for beacons that are emitted from one or more WLANs. Once, the MS receives a beacon from a WLAN it can access that WLAN. To access the WLAN, the MS could send a signal to the BSS informing the BSS and possibly a gateway GPRS service node (GGSN) that it has received a beacon from the WLAN. Then, the MS can receive a signal from the BSS (or GGSN) which contains information (e.g., password, encrypted key) that enables the MS to access the WLAN.

Abstract: The present invention relates to an apparatus and a method for measuring interference levels in a telecommunication system comprising a radio base station communicating with at least one in-house mounted transceiver, the transceiver defining a communication range in which it is responsible for handling, communication terminals, such as mobile phones or computer terminals. By means of at least one scanner the apparatus synchronises with transmitted information from the base station to the transceiver in a time regime. The scanner is connected to measurement means for measuring the interference level on transmitted information and the measurement means is adapted to compare measured interference levels with each other an thereby improve transmission between the base station and the transceiver on a favourable frequency, whereby the problem of interference on allocated traffic channels is alleviated.
