摘要:
The present invention relates to a network element such as a base station controller, for a cellular network comprising one or more cells being served by at least one transceiver for enabling communication sessions with a mobile cellular terminal. The element comprises communication means adapted for communicating with other network nodes. The element further comprises register software adapted for creating, configuring and/or removing information about the cell on which a communication session is running and its relationship to at least one neighbouring cell to which a running communication session can be transferred and resource management software adapted for managing the communication session between the transceiver and the terminal. The element is further characterized in that the register software is adapted for creating and/or configuring a counter value on each relationship to a neighbouring cell, which value limits the time or number of events the neighbouring cell can be part of so that when the counter value corresponds to a removal value the relationship is removed.

摘要:
Nodes such as base stations in a mobile communication network are divided and grouped into management clusters. One of the nodes in each management cluster is selected to be a master node. The master node aggregates performance data for each of the nodes in its assigned cluster, and sends a consolidated performance management report containing the aggregated data to a management entity.
摘要:
A cluster-based, delegated software upgrade scheme facilitates software upgrade for radio base station nodes comprising a cluster of a flat radio access telecommunications network. The plural radio base stations are grouped into clusters (30), and a master radio base station (RBSM) designated for each cluster. The master radio base station (RBSM) is used to initiate software upgrade of the radio base stations comprising the cluster. The master radio base station (RBSM) can also perform a monitoring of implementation of the software upgrade at the radio base stations of the cluster, and on the basis of the monitoring, determine whether a cluster-wide software upgrade is successful. In one of its example modes, the master radio base station can further prepare a software upgrade report which confirms/summarizes implementation of the software upgrade at the radio base stations of the cluster.
摘要:
In a cellular wireless communications network, measurements are received from a plurality of user equipments relating to the reference signal received powers from a plurality of other cells of the cellular wireless communications network For other cells of the cellular wireless communications network having a physical cell identity (such as a scrambling code) that is the same as a physical cell identity of that first cell, it is determined from the received measurements whether a mutual potential interference level with that cell exceeds a threshold If so, an alternative physical cell identity is proposed, that would cause a mutual potential interference level between the cell or the potentially interfering cell and another cell already using that alternative physical cell identity that is lower than the mutual potential interference level between the cell and the potentially interfering cell.

摘要:
A pair of stepping motors form the basis of a coarse-fine drive mechanism. A coarse stepping motor imparts rotational motion through a drive gear to a driven shaft, and a fine stepping motor imparts linear or axial motion to the same shaft by means of a cam. The driven shaft is part of a system which integrates the afore-mentioned rotational and axial motions in order to rapidly and accurately move and position a rack through a wide range of drive increments which is afforded by the presence of the coarse and fine drives.
