A method for grouping and ungrouping omni-cells in a mobile communications system using a common PN-offset in one channel so as to manage a plurality of cells in a manner similar to a method by which an omni-cell is managed using a unique PN offset. Cell grouping is performed by generating a common PN offset in each of the cells to be grouped by selecting an unused path in each channel of each cell, and then changing the unique PN offset of each of the cells to the common PN offset of the selected path.

[ What is claimed is:] [1.] A method for grouping a plurality of cells in a cellular communication system, each of said cells including at least two channels each having a plurality of paths and each of said cells having a distinct PN (pseudorandom noise) offset pilot signal being assigned to a first path of said plurality of paths, said method comprising the steps of:generating a common PN (pseudorandom noise) offset pilot signal at a second one of said paths of said channels in each of said plurality of cells, said common PN offset pilot signal not being utilized as said unique PN offset pilot signal at any of said plurality of cells;determining if said common PN offset pilot signal and said distinct PN offset pilot signals are both emitted from an antenna;recognizing, by a user terminal, a signal strength of said common PN offset pilot signal;determining whether said signal strength of said common PN offset pilot signal exceeds a first preselected threshold if it is determined that said common and distinct PN offset signals are outputted from said antenna;reporting said signal strength to a BTS (base station transceiver subsystem) if said signal strength exceeds said first preselected threshold;establishing communication with users through said first and second paths;weakening simultaneously said signal strength of distinct PN offset of said plurality of cells during said communication in said first and second paths;reporting weakening of said distinct PN offset pilot signal to said BTS by said users of said plurality of cells;commanding by said BTS to terminal equipment to receive only said common PN offset signals; andterminating, by said terminal, from transmitting and receiving said distinct PN offset signal, thereby grouping said plurality of cells having said common PN offset by transmitting and receiving only said PN offset.
