FIELD: wireless communication.
SUBSTANCE: method for performing a search call contains stages, at which: a network device determines a system frame number SFN2 and then a system frame number SFN1 based on SFN2, determines a target synchronization signal block (hereinafter – SSB) of a set of SSB of the current broadband carrier, and sends a search call message to a terminal device according to SFN1 in the location in a frequency domain, where the target SSB is located.
EFFECT: reducing the load, when transmitting the search call message on the network side by UE, while forming the set of cell beams.
