Claim:
A method of system selection in a mobile wireless device, the mobile wireless device operable on a 3GPP wireless network, the method comprising: storing an absolute radio frequency channel number (ARFCN) table in a memory of the wireless mobile device; retrieving location data associated with the wireless device prior to accessing the wireless network; determining an ARFCN associated with the retrieved location data from the ARFCN table stored in memory, the determined ARFCN comprising a suspension tag specifying an expiry period of the determined ARFCN; performing a system selection using the determined ARFCN; determining that the system selection using the determined ARFCN is successful and that the suspension tag is expired; and sending an indication to a remote server maintaining a remote ARFCN table that the ARFCN is in use, wherein the ARFCN table comprises a routing area identifier (RAI); and wherein the RAI associates with the determined ARFCN.
