A method for Packet Switched handover processing, comprising: receiving, by a network (32, 42), a failure cause value from a terminal (31, 41), when a failure cause value is determined by the terminal (31, 41) according to a cause of a handover failure if the handover failure occurs, wherein different failure cause values correspond to different causes of the handover failure; and performing a corresponding handover control by the network (32, 42) according to the failure cause value, characterized in that if the network (32, 42) determines that a type of the handover failure is no response on target cell failure according to the handover failure cause, the network (32, 42) prevents the terminal (31, 41) in a source cell from performing handover to a target cell in a period of time; and the method further comprises: if the network (32, 42) determines that a type of the handover failure is a PS handover failure other than no response on target cell failure, the network (32, 42) performs a corresponding parameter correction according to the failure cause value; wherein the process of the network (32, 42) performs a corresponding parameter correction according to the failure cause value, comprises: the network (32, 42) modifies the classmark information of network maintenance, or checks and corrects the format of the delivered parameter, and makes the allocated frequency point fall in the frequency band which is supported by the terminal (31, 41). receiving, by a network (32, 42), a failure cause value from a terminal (31, 41), when a failure cause value is determined by the terminal (31, 41) according to a cause of a handover failure if the handover failure occurs, wherein different failure cause values correspond to different causes of the handover failure; and performing a corresponding handover control by the network (32, 42) according to the failure cause value, characterized in that if the network (32, 42) determines that a type of the handover failure is no response on target cell failure according to the handover failure cause, the network (32, 42) prevents the terminal (31, 41) in a source cell from performing handover to a target cell in a period of time; and the method further comprises: if the network (32, 42) determines that a type of the handover failure is a PS handover failure other than no response on target cell failure, the network (32, 42) performs a corresponding parameter correction according to the failure cause value; wherein the process of the network (32, 42) performs a corresponding parameter correction according to the failure cause value, comprises: the network (32, 42) modifies the classmark information of network maintenance, or checks and corrects the format of the delivered parameter, and makes the allocated frequency point fall in the frequency band which is supported by the terminal (31, 41). if the network (32, 42) determines that a type of the handover failure is a PS handover failure other than no response on target cell failure, the network (32, 42) performs a corresponding parameter correction according to the failure cause value; wherein the process of the network (32, 42) performs a corresponding parameter correction according to the failure cause value, comprises: the network (32, 42) modifies the classmark information of network maintenance, or checks and corrects the format of the delivered parameter, and makes the allocated frequency point fall in the frequency band which is supported by the terminal (31, 41). the network (32, 42) modifies the classmark information of network maintenance, or checks and corrects the format of the delivered parameter, and makes the allocated frequency point fall in the frequency band which is supported by the terminal (31, 41).
