摘要：A method and apparatus for searching for and reporting Public Land Mobile Networks “PLMNs” in a mobile telecommunications system, the method comprising, at a mobile device: initiating a scan to find Public Land Mobile Networks; when a cell of a PLMN is detected on a frequency, then reading system information to determine one or more PLMN identities of the detected cell; determining whether the detected cell operates in a frequency band supported by the mobile device; when it is determined that the detected cell does not operate in a band supported by the device, omitting adding the associated one or more PLMN identities from a first of PLMNs,and otherwise adding the one or more PLMN identities to the list of PLMNs; and reporting the list of PLMNs.
