  • Patent number: 11432198
    Abstract: According to certain embodiments, a method by a network node (860) for shifting cell borders of multiple frequency bands includes deploying at least two frequency bands. Each of the at least two frequency bands have at least two cells, and each cell have an associated cell coverage area within a common target coverage area. Each of the at least two frequency bands are associated with a respective interference area along a respective cell border, and each interference area is characterized by interference from an adjacent cell. The associated cell coverage area of at least one of the at least two frequency bands is adjusted such that the respective cell border of the at least one of the at least two frequency bands is shifted to reduce a common interference area of the at least two frequency bands. The common interference area is an area where the respective cell borders of the at least two frequency bands overlap.

  • Patent number: 7970399
    Abstract: Method and arrangements for enabling improved handover of a user equipment (3) communicating in a first radio access network (1) utilizing a first radio access technology (RAT), where the user equipment (3) measures a first parameter and a second parameter for a plurality of neighboring cells (20) of at least a second radio access network (2) utilizing WCDMA, reports the measured parameters to a node (10) in the first network (1) and handover is initiated to one of the cells (20) in the second network (2) based on both of the reported first parameter and second parameters.

  • Patent number: 7187934
    Abstract: Load redistribution and other benefits may be achieved by dynamically distributing or “steering” idle mobile stations to a particular cell or area. For example, idle mobile stations may be steered from a loaded cell to less loaded cells by changing one or more cell broadcast parameters.
