Abstract:

Embodiments of the present invention disclose a method and a device for releasing a PDN connection, and user equipment. The method for releasing a PDN connection comprises: user equipment can determine a service transmission status of a target packet data network (PDN) connection, location area information corresponding to the target PDN connection, and a current location of the user equipment; and if the user equipment determines that a first condition is satisfied, the user equipment can release the target PDN connection, wherein the target PDN connection is any one or more of a plurality of PDN connections maintained by the user equipment, and the first condition may comprise: the service transmission status of the target PDN connection is that service transmission stops, and a location area indicated by the location area information corresponding to the target PDN connection does not include the current location of the user equipment. In this way, the present invention prevents the problem in which an arbitrary release of a PDN connection causes reestablishment of a PDN connection and accordingly a waste of network resources.
