<p>Disclosed are a cell searching method and device, comprising: performing timeslot synchronization; identifying a primary scrambling code group and performing frame synchronization according to hash values of code numbers of secondary synchronization codes (SSC) of any several consecutive timeslots; and obtaining primary scrambling code in the primary scrambling code group according to the primary scrambling code group, so as to complete cell searching. In the present invention, possible SSC code of each timeslot is determined, and then, a scrambling code group is searched for through a hash method, so that the problem of complex calculation and large storage in processes of frame synchronization and identification of a primary scrambling code group in cell searching in related technologies is solved, and the processes of identification of a scrambling code group and frame synchronization can be completed as long as hash values of code numbers of SSCs of several consecutive timeslots are calculated; and the amount of related calculation is reduced by about two times, and the process of frame synchronization is accelerated.</p> |
