A cell merging method, comprising receiving, by a coordination cell, a cell merging instruction sent by an initiating cell and used for instructing merging of the initiating cell and the coordination cell; maintaining, by the coordination cell, a cell parameter of the coordination cell and a cell parameter of the initiating cell according to the cell merging instruction; handing over, by the coordination cell, user equipments, UEs, served by the coordination cell to a first shadow cell and synchronizing information of the handed over UEs with the initiating cell, wherein the first shadow cell has the cell parameter of the initiating cell and is maintained by the coordination cell; and after all UEs served by the coordination cell are handed over to the first shadow cell and it is determined that information of all the handed over UEs is synchronized with the initiating cell, the coordination cell stopping maintaining the cell parameter of the coordination cell; wherein the cell parameter comprises a reference signal, RS, a primary synchronization signal, PSS, a secondary synchronization signal, SSS, a master information block, MIB, and a system information block, SIB, of the cell; and wherein the maintaining, by the coordination cell, the cell parameter of the coordination cell and the cell parameter of the initiating cell according to the cell merging instruction comprises: transmitting the reference signal, RS, the primary synchronization signal, PSS, the secondary synchronization signal, SSS, the master information block, MIB, and the system information block, SIB, of both the initiating cell and the coordination cell. receiving, by a coordination cell, a cell merging instruction sent by an initiating cell and used for instructing merging of the initiating cell and the coordination cell; maintaining, by the coordination cell, a cell parameter of the coordination cell and a cell parameter of the initiating cell according to the cell merging instruction; handing over, by the coordination cell, user equipments, UEs, served by the coordination cell to a first shadow cell and synchronizing information of the handed over UEs with the initiating cell, wherein the first shadow cell has the cell parameter of the initiating cell and is maintained by the coordination cell; and after all UEs served by the coordination cell are handed over to the first shadow cell and it is determined that information of all the handed over UEs is synchronized with the initiating cell, the coordination cell stopping maintaining the cell parameter of the coordination cell; wherein the cell parameter comprises a reference signal, RS, a primary synchronization signal, PSS, a secondary synchronization signal, SSS, a master information block, MIB, and a system information block, SIB, of the cell; and wherein the maintaining, by the coordination cell, the cell parameter of the coordination cell and the cell parameter of the initiating cell according to the cell merging instruction comprises: transmitting the reference signal, RS, the primary synchronization signal, PSS, the secondary synchronization signal, SSS, the master information block, MIB, and the system information block, SIB, of both the initiating cell and the coordination cell.
