The invention discloses a method and a device for searching systems and frequency points. The method comprises the following steps: signal energy of each grid is obtained according to a frequency grid within a frequency range; energy of each system on minimum bandwidth can be respectively obtained according to the signal energy of each grid; energy of each system on the minimum bandwidth can be collected together for ordering; and a frequency point and a system with maximal specific quantity energy in ordering result are switched in. By adopting the embodiment of the invention, the energy on the minimum bandwidth of each system on frequency bands can be obtained and ordered, the switched system can be determined according to the ordering result. Therefore, the access success rate at the terminal in later access is improved.
Description
System and frequency point search method and device technical field The present invention relates to the field of communication technologies, and in particular to a method and device for searching standard and frequency points. Background technique With the rapid development of wireless communication technology, more and more spectrum resources will be allocated to wireless communication or cellular communication. The frequencies used in different countries, regions or wireless networks may be part of spectrum resources. When the UE (User Equipment, user terminal) is turned on, the UE may not know which frequencies are currently accessible. At the same time, within the same frequency range, multiple frequency points of multiple access systems may exist simultaneously. Therefore, for the UE, it does not know which mode access should be used on which frequency point in this frequency band when it is turned on. A common method for this problem in the prior art is: in each...
