METHOD OF FREQUENCY SCHEDULING IN MOBILE COMMUNICATION SYSTEMS Russian patent published in 2009 - IPC H04B7/24 

FIELD: communication facilities.

SUBSTANCE: method concerns electric and radio communication, particularly method of frequency scheduling in mobile land communication systems. To achieve the effect method involves spatial separation of GSM 900 standard frequency bands by frequency bands of DCS 1800. If frequency resource is not sufficient in GSM 900 standard, operator designs focused areas of DCS 1800 standard including one or more base DCS 1800 stations. Focused area of DCS 1800 standard is introduced to separate GSM 900 standard areas in space and increase additional protection interval between cells with recurrent frequencies, and to relieve additional client load, thus resulting in increased possibilities for frequency recursion in both standards.

EFFECT: expanded coverage area of mobile land communication systems, improved quality of services provided to clients of electric and radio communication networks, improved parametres of electromagnetic compatibility.
