Abstract  Abstract

The embodiment of the present invention provides an uplink synchronization method and apparatus wherein the method includes: according to the timing advance of the first frequency point obtaining the timing advance of the second frequency point; sending data at the uplink sending time corresponding to the timing advance of the second frequency point. The apparatus includes: first obtaining module for obtaining the timing advance of the second frequency point according to the timing advance of the first frequency point; sending module for sending data at the uplink sending time corresponding to the timing advance of the second frequency point. The embodiment of the present invention can obtain the timing advance TA of the second frequency point according to the timing advance TA of the first frequency point and it need not to execute the random access channel RACH access process at the second frequency point the network resource occupied by the RACH access process and the time delay brought by the RACH access process can be reduced effectively thereby the performance of the whole system can be improved.
