Abstract:
The present invention provides a method of PLMN selection subsequent to a change in cell for a mobile radio communications device in a multi-network cellular environment, the method including the steps of monitoring system information within a mobile radio communications device to determine the availability of a HPLMN or any other higher priority PLMN than current registered PLMN, and selecting the said HPLMN or higher priority PLMN than current registered PLMN if identified as available, and also a related network-sharing-capable UE that, when registered with a visitor PLMN, can readily check the availability of its HPLMN or any other higher priority PLMN in the system information whenever it moves to a new location area and, assuming the HPLMN or higher priority PLMN to be found, can then reselect to that PLMN.
