FIELD: telecommunication equipment. SUBSTANCE: method legibility for communication line between wireless base station and equipment for issuing admission and routing of calls involves authentication of wireless base station for communication to equipment for issuing admission and routing of calls and authentication of equipment for issuing admission and routing of calls for communication to wireless base station. Preferably, method for authentication of wireless base station uses first arbitrary number, which is generated by equipment for issuing admissions; while method for authentication of equipment for issuing admissions uses second arbitrary number which is generated by wireless base station. Communication line between wireless base station and equipment for issuing admissions is achieved, when both wireless base station and equipment for issuing admissions have been tested for authenticity. EFFECT: increased functional capabilities. 8 cl, 1 dwg
