The invention discloses a resource 
seizing method for a long term evolution (LTE) 
system during service congestion, comprising the following steps: determining 'a 
seizing service', 'a seized service 
queue' and 'candidate services' which are distributed with the priority lower than that of the 
seizing service in the seized service 
queue; and selecting m candidate services in the seized service 
queue, wherein, the accumulated sum of 
available bit rate (ABR) of the m candidate services is larger than the ABR of the seizing service in the acceptation and refusing directions of the seizing service, while the accumulated sum of the ABR of m-1 candidate services is smaller or equal to the ABR of the seizing service; if the m candidate services exist, performing forced release 
processing on the m selected candidate services, accepting the seized service to finish the seizing process; and if the m candidate services do not exist, determining that the seizing is failed, and putting the seizing service into a failure acceptation 
list. By utilizing the method, the services with high access 
bit rate and low priority can be selectively released, thus ensuring to seize the high-priority services accessed by the user.
