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： An object of the present invention is to provide a mechanism for handling a handover in a more efficient way. The invention relates to a method in a mobility controller (180) in a radio access network for preparing a handover. The method comprises the following steps to be taken during data transmission between a mobile terminal (140) and a source base station (120), before the handover: Sending a request to a candidate base station (122), which request aims at measuring and reporting timing alignment to be used by the mobile terminal (140) when communicating with the destination base station (122) after the handover, if the candidate base station becomes the destination base station (122) after the handover; receiving a report from the destination base station (122) comprising said requested timing alignment; and when the destination base station (122) is selected among the at least one candidate base stations, sending a message to the mobile terminal (140) to use said timing alignment received from the destination base station (122) when communicating with the destination base station (122) after the handover.

摘要： In a Long Term Evolution (LTE) cellular radio system method of selecting a physical cell id (PCI) of a LTE cell is obtained by reporting PCIs of neighbors and also a parameter indicating each neighboring cell's relevance also termed visibility to the cell. A new cell added in a cellular radio, system can then make an improved selection of a PCI already at the very first neighbor relation establishment; even if all available PCIs are already used in the vicinity.

摘要： An analogue mobile telesystem has traffic channel cells (C1), each of which includes a base station (A-G). These base stations handle combined control channels (PAC) for paging a mobile station (MS), and also access channels (AC) for establishing connections to or from the mobile station (MS). The mobile station has information concerning the frequencies of all of the access channels and the connections are established on duplex traffic channels (TC). The geographical area covered by respective traffic channel cells (C1) is determined by virtue of enabling all traffic channels (TC) within this area to be used for predetermined, common purposes. Each of the traffic channel cells (C1) has at least two access channels (PAC, AC) spaced apart at a desired frequency distance and having the same radio coverage as the traffic channels (TC). When desiring access, the mobile station (MS) scans the strength or power of all access channels on two separate occasions at a mutual spacing of 20 milliseconds. The duplex access channels (PAC, AC) assist the mobile station (MS) in finding the strongest access channel (PAC, AC) despite heavy fading. The mobile station (MS) thereby establishes a connection on the traffic channel (TC) in the most suitable cell (C1) having the highest signal strength. Unnecessary handoffs are avoided and speech quality is improved.

摘要： A radio network node and method for improved control of handover decisions of a User Equipment (UE) in a wireless communications network. The UE is in a served cell and is moving towards a neighboring cell. The network node obtains neighboring cell characteristics and determines a mobility threshold based on the obtained neighboring cell characteristics. The handover decisions of the UE to the neighboring cell are then controlled based on the determined mobility threshold.

摘要： A telecommunications system comprises a serving radio base station and a candidate radio base station which are different with respect to at least one of frequency and radio access technology. The serving radio base station comprises a radio base station to which a wireless mobile station provides measurement reports. A method comprises the serving radio base station allowing the mobile station to obtain information broadcasted by the candidate radio base station. The information is either information for locating Cell Global Identity (CGI) of the candidate radio base station or the Cell Global Identity (CGI) itself of the radio base station. The mobile station obtains the information from the candidate radio base station during at least one reading gap. The reading gap is a time period in which the mobile station does not receive information from the serving radio base station.

摘要： In a mobile telecommunication system the transmission quality is dependent on a wide range of radio conditions. A method for extracting a useful estimation of the radio environment of a mobile station in communication in order to predict how the radio conditions will change in the near future for a considered mobile station in the near future. A measurement report is sent from the mobile station to the base station. The quality measure in the measurement report is filtered over the area by a smoothing filter (220), and then processed through an updating filter (230) resulting in a time varying map (240). Several maps are classified (260). Classified data are grouped (270) resulting in the final map, which is stored in a database (280). The final map may be used to enhance the performance of radio network algorithms.
