A Method of Cell Reselection in a Wireless TelecommunicationsDevice Operative with a Plurality of Radio Access Networks

摘要

Apparatus and a method of cell reselection in a wireless telecommunications device operative with a plurality of radio access networks are disclosed. The method comprises, when the device is camped on a first radio access network: ranking cells in a neighbouring list according to cell reselection criteria; considering for cell reselection a cell in the neighbouring list; when the cell in the list is a cell of a second radio access network different from the first radio access network, applying an algorithm for cell reselection from the second radio access network to the first radio access network; and when the algorithm as applied would result in reselection to the first radio access network, considering for cell reselection another cell in the list.
