Patent number: 8554266Abstract: Mobile user equipment for use in a cellular communications environment performs an improved cell selection on transitions out of a connected mode state. The transitions might be from one connected mode state to another or from a connected mode state to idle mode. The improvement in cell selection lies in assembling the list of candidate cells prior to cell selection. In the prior art, the list of candidate cells would usually be restricted to the serving cell or active cells supporting communication between the equipment and the network prior to transition. In embodiments of the invention, the list might comprise cells which are not the serving cell or which are outside the active set, for example a network-preferred cell or cells neighboring the serving cell or cells of the active set.Type: GrantFiled: February 15, 2011Date of Patent: October 8, 2013Assignee: BlackBerry LimitedInventors: Nicola M. Funnell, Gideon Roberts, Andrew John Farnsworth, Richard John George, Gjalt de Jong
