The invention provides a resource allocation method for a network element adapted for multimedia broadcast and synchronized services in a mobile communication system, the mobile communication system comprising a plurality of base stations synchronized for data transmission, the method comprising: inputting a set of synchronized subframe numbers per radio frame and a total number of radio frames, wherein each radio frame contains a predefined number of subframes; selecting a first value of the set of synchronized subframe numbers; first allocating the first value as a number of synchronized subframes per frame to the total number of radio frames; second allocating the first value as the number of synchronized subframes per frame to a first half of the total number of radio frames, if the first allocating step is not performed; and selecting a second value of the set of synchronized subframe numbers. The method further comprises: third allocating the second value as the number of synchronized subframes per frame to the first half of the total number of radio frames, if the first and second allocating step is not performed; forth allocating the second value as the number of synchronized subframes per frame to a second half of the total number of radio frames, if the second allocating step is performed; selecting a third value of the set of synchronized subframe numbers; wherein one of the allocating steps is performed according to bandwidth requirements of the multimedia broadcast and synchronized services.
