The invention provides a terminal, a base station side device, a terminal device, a base station and a wireless communication method. A device of a terminal side in a wireless communication system comprises a search unit and a synchronizing unit, wherein the search unit is used for searching a target cell by means of a synchronous signal sequence corresponding to a to-be-searched target frequency range, the synchronizing unit is used for conducting synchronizing on the basis of synchronous signals detected by the search unit and synchronizing the device to the target cell, the search unit searches the target cell by means of the synchronous signal sequence in a first subset of a synchronous signal sequence set when the target frequency range is the first frequency range, and the first subset is a proper subset of the synchronous signal sequence set. According to the technology, the number of matching times of synchronous signal sequences in the cell search process is decreased, and time is shortened when the user device is synchronized to the target cell.

The invention provides a method and a device for classifying POI information. The method comprises the steps as follows: extracting name information of the POI information to be classified; performing word segmentation to the name information and obtaining a plurality of segmentation fragments; matching the plurality of segmentation fragments with a classification keyword according to a preset matching sequence; determining a POI classification directed by the classification keyword corresponding to the segmentation fragment which is matched successfully at first as a belonged classification of the POI information to be classified. The method and the device of the invention could reduce the time needed for performing the word segmentation because only the name information of the POI information to be classified needs to perform the word segmentation, and then perform keyword matching to the segmentation fragments obtained by performing the word segmentation so as to correspondingly reduce the matching times while performing the keyword matching afterwards based on fewer segmentation fragments obtained by performing the word segmentation and increase the run time of POI information classifying process. Simultaneously, the classification accuracy determined based on the name information is relative high because the name information and the POI information have high correlation, thereby improving efficiency of POI information classification as a whole.
