ABSTRACT:
An initial search for locating cells in a telecommunication system includes defining a set of carrier frequencies to be searched, and selecting as a cell search mode either a wide cell search mode or a narrow cell search mode, wherein selecting the cell search mode is based on a level of frequency generation accuracy. The wide cell search mode searches a wider frequency range than the narrow cell search mode searches. For each carrier frequency in the set of carrier frequencies to be searched, a most-recently selected cell search mode is used when searching for a cell transmitting on the carrier frequency. The narrow cell search mode is used only when the level of frequency generation accuracy is better than an expected worst level of frequency generation accuracy.
