METHOD FOR INITIAL SCANNING OF FREQUENCIES, FREQUENCY SCANNING CONTROLLER, AND APPARATUS |
摘要 |
<p>A method for initial scanning of frequencies at start-up of a multi-band cellular communication apparatus is disclosed. The method comprises determining whether there is any interfering signal from any other communication system transmitting at a frequency in vicinity of frequencies of frequency bands of which the multi-band cellular communication apparatus is supposed to establish contact with a base station in at least one of the frequencies within the frequency bands. If the determination gives a result of no interfering signal, a first scan procedure is applied comprising plain scanning of the frequencies of the frequency bands of which the multi-band cellular communication apparatus is supposed to establish contact with a base station in at least one of the frequencies within the frequency bands, or if the determination gives a result of an interfering signal, a second scan procedure is applied, taking into account the determined interfering signal. A frequency scanning apparatus for initial scanning, and a radio access circuitry for such initial scanning is also disclosed.</p> |
