Abstract: Undesired interfering signal sources within a wireless communication network disturb the radio communication between radio base stations and mobile stations. The invention presents a method and device wherein the beam pattern of an antenna, comprising two or more sectorised antenna elements with overlapping beam patterns, is adapted such that the position of the source of interfering signal is preferably substantially located within the overlap of said beam patterns. The one or more beam patterns are adapted in bearing such that the resulting interfering signal is reduced by the superimposing effect of radio wave propagation within the overlap area.

Abstract: A method in a communication system comprising a access network with Radio Network controllers (RNC) and radio base stations (RBS or Node B) consisting of main units (MU) which performs base band signal processing and one or more radio remote units (RRUs) which converts between baseband and radio frequencies and transmits and receives signals over one or more antennas, covering cells, and one or several User equipment (UE or Phones) moving closer and closer to another cell, which said network is made aware of and then it will initiate a handover process, during which the call will be transferred from one cell to another cell within said radio base station (RBS or Node B)or to a cell in another Radio base station (RBS or Node B)in said communication network. Said handover process interact with a memory containing a list (softer handover group) of said radio remote units (RRUs) capable of doing softer handover with each other using the same Rake receiver.

Abstract: A load condition of a cell is determined without having to measure one or more radio parameters pertaining to the cell load, e.g., interference level. Based upon that determined load condition, a traffic condition of the cell may then be regulated, e.g., admission and/or congestion control, transmit power control, etc. The load condition is determined simply and accurately by observing the value (absolute or weighted) of transmit power control commands issued in the cell over a particular time period. To identify potential “false alarms” of increased cell loads, a radio parameter associated with another frequency band in another cellular system that impacts the load condition of the cell in the current cellular system is measured. A traffic condition in that cell is regulated based upon the determined load condition in the cell taking into account the measured radio parameter.

In one example implementation, the number of increase transmit power commands issued in a cell over a particular time period is determined relative to a total number of transmit power commands, (i.e., both increase and decrease), issued in the cell for that same time period. If the number of increase transmit power commands relative to the total number of transmit power commands exceeds a threshold, an overload condition may be indicated.

Abstract: Redundancy is established over a radio link (RL) between peripheral units (28) of a communications network (20). The communications network includes a central unit (26) which is connected by a first link (LA) to a first peripheral unit (28A) and by a second link (LB) to a second peripheral unit (28B). The radio link connects the first peripheral unit and the second peripheral unit. Redundancy is realized by providing communication between the central unit and the second peripheral unit over the radio link upon failure of the second link. In one illustrated example implementation, the communications network is a radio access network of a telecommunications system, with the central unit being a radio network control (RNC) node and the first peripheral unit and the second peripheral unit being differing base stations of the radio access network.
