Claims define the patent's legal scope. Independent claims stand alone; dependent claims (nested) narrow them. Click a claim to expand its dependents.
A method for use in a mobile device comprising: when the mobile device is connected to a gene ri c access network (GAN) cell, receiving information comprising characteristics pertaining to one or more neighbour cells in a network that are not GAN cells; determining at least a list of candidate neighbour cells for handover from the GAN cell to a cell that is not a GAN cell as a function of the information, the determining comprising performing at least one of: reducing processing load of the mobile device directed to generating the list, and performing at least some of the processing load of the mobile device directed to generating the list prior to a trigger initiating handover.
The method of claim 1 wherein determining at least a list of candidate neighbour cells for handover from the GAN cell to a cell that is not a GAN cell as a function of the information comprises determining at least a list of candidate 3G cells for handover from the GAN cell to a cell that is not a GAN cell as a function of the information.
