PURPOSE: A cell border recovery method of a mobile switching system checks a cell border when a cell is transmitted from a cell slave board to a cell master board on a back plane, recovers a corresponding cell border, and transmits a cell. CONSTITUTION: A cell border recovery method of mobile switching system activates (S51) a cell effective signal if a cell to be transmitted exists, and checks whether a cell border is normal or not by checking a signal level of a cell start signal. If the corresponding cell border is normal, the method activates (S53) a new cell effective signal. Activated enable signal is provided (S54) as a new enable signal, and then a cell is transmitted(S5). Thereby, a cell is transmitted to a corresponding cell master board if the cell border is at a normal state, a stability of a mobile switching system is enhanced. |
