  • Publication number: 20100135255
    Abstract: A method for detaching User Equipment (UE) is disclosed to detach the UE in case of signaling reduction. The method includes the following steps: a UE detachment operation of a first network access control entity is triggered, where the detachment operation is a complete detachment operation; the first network access control entity detaches the UE according to the detachment operation type, and triggers the complete detachment of a second network access control entity; and the second network access control entity performs the detachment operation according to the trigger operation of the first network access control entity. Thus, after the UE is detached from a network access control entity, the network access control entity may notify another network access control entity by various means, so that another network access entity implements subsequent processes.
