Abstract: Embodiments of the present invention provide an apparatus, a device, and a method. The method comprises: when it is detected that a position of user equipment changes, determining whether an area served by an anchor gateway through which the user equipment connects to a packet data network is consistent with an area served by a data forwarding gateway; sending, to the user equipment when a result of the determining is no, a packet data network connection release request that carries a reconnection indication; receiving a packet data network reconnection request sent by the user equipment; selecting an anchor gateway that serves an area consistent with the area served by the data forwarding gateway; connecting the user equipment to the packet data network by using the selected anchor gateway. Voice service experience of a user may be improved by using the method in the present invention.
