A data filtering method for removing invalid data in 3G data stream which is received. The data filtering method includes the following steps. At first, a step (a) of receiving a 3G data stream continually is performed. Then, a step (b) of determining whether the 3G data stream comprises a complete filtering unit is performed. If the 3G data stream comprises a complete filtering unit, a step (c) of determining whether the 3G data stream includes invalid data is performed. If the 3G data stream includes invalid data, a step (d) of marking the invalid data according to a predetermined protocol is performed. Finally, a step (e) of filtering out the marked invalid data is performed.
