    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: A method in a wireless network containing a first node and an adjacent second node for determining an uplink received power target value of the second node to be used by a user equipment which is to be served by the second node includes establishing the uplink received power target value of the first node. The method also includes obtaining the downlink power capacity of the first node and obtaining the downlink power capacity of the second node. Additionally, the method includes calculating the difference in downlink power capacity between the first node and the second node and determining the uplink received power target value of the second node based on the calculated difference in downlink power capacity between the nodes and the established uplink received power target value of the first node.

    摘要: A method for uplink power control at a mobile station which is served by a base station of a communications network comprising a plurality of base stations is provided where the power spectrum density of the mobile station is adaptable based on the bandwidth scheduled to the mobile station. The suggested power spectrum adaptation is obtained by providing for a switch to an alternative power control mode which enables for transmit power boosting at the mobile station. The decision whether to apply the suggested power spectrum adaptation can be made at the base station which is serving the mobile station, or at a selected mobile station.
