FIELD: mobile communications. ^ SUBSTANCE: for providing communication services from one point to a set of points in existing infrastructure of cell phone communication system each client station, participating in such service, receiving jointly used channel of direct communication line and in several variants of realization of dedicated channel of direct communication line. Because transfer via direct communication channels from adjacent sectors represents an interference to transmission from sector, servicing client station, it is recommended to control transmitted power of direct communication line channel to achieve minimal acceptable level. Also, transmission from each client station being a member of group via channel of reverse communication line represents an interference to other client stations. Therefore it is recommended to control transferred power of signal of back communication line to achieve minimal level of signal. ^ EFFECT: realization of group services in existing infrastructure of wireless cell phone communication system. ^ 23 cl, 3 dwg |
