Document Type and Number:
WIPO Patent Application WO/2007/026679
Kind Code:
A1
Abstract:
A method for optimizing the public land mobile communication network search using
a mobile terminal having a nonvolatile memory and a SIM card. This method comprises
the steps of searching for a PLMN in accordance with priority information registered
in the SIM card; determining whether the SIM card includes any priority information
related to at least one particular wireless access technique associated with
the PLMN having been found; if yes, selecting a cell of this PLMN; if no, determining whether
the nonvolatile memory includes any information related to at least one particular
wireless access technique that is to be selected on a priority basis within the
country of the PLMN; if yes, selecting a cell of a PLMN in which the particular wireless
access technique has been developed; and if no, selecting a cell in which a wireless
access technique, which is established beforehand by default in the nonvolatile
memory for all countries that are not listed in the nonvolatile memory, has been
developed.
