Abstract: The embodiments of the application disclose a mobile handover method. The method includes: a first network device receives first information, and learns that a first terminal device is handed over to a target access network device. The first network device sends second information to a second network device, and the second network device determines, based on the second information, whether to reselect a target user plane function device for the first terminal device; and/or the first network device sends third information to a third network device, and the third network device determines, based on the third information, whether to reselect a target application server for the first terminal device. If the target user plane function device and/or the target application server need/needs to be reselected, a user plane function device and/or an application server need/needs to be handed over in a timely manner.

Abstract: A paging method, a paging device, and system are described. A mobility management network element (MME) obtains location information of user equipment (UE) in a non-3rd Generation Partnership Project (3GPP) network, where the UE already accesses the non-3GPP network. The MME receives a downlink data notification message, where the downlink data notification message carries an identifier of the UE. The MME pages the UE according to the location information of the UE in the non-3GPP network. In some implementations, a paging range may be determined according to the location information of the UE in the non-3GPP network, and a paging message does not need to be sent to all base stations in a registration area of the UE.

Abstract: Embodiments provide a network handover method, apparatus, device, and system and relate to the communications field. The method is used in a control node and include: acquiring first state information of a WLAN AP that UE accesses and second state information of a cellular network corresponding to a location of the UE. If it is determined that the first state information and the second state information meet a preset first handover condition, the method includes generating first handover information, and sending the first handover information to a handover node, so that the handover node sends, to the UE, a first handover command that is generated according to the first handover information, and the UE attaches to the cellular network indicated by the first handover command, receives an IP address of the UE in the cellular network, and implements a handover from a WLAN to the cellular network.

Abstract: Embodiments of the present disclosure provide a mobility management method, so as to effectively ensure normal communication between user equipment and a base station without using an anchor device, and ensure continuity of a service between the user equipment and a communication peer end. A specific solution is: establishing, by user equipment, a first substream to a communication peer end, when the user equipment is handed over from a first base station to a second base station, obtaining, by the user equipment, a second IP address when a second gateway and a first gateway are not a same gateway, establishing, by the user equipment, a second substream to the communication peer end after obtaining the second IP address, canceling, by the communication peer end, the first substream after the second substream is established, and releasing, by the first gateway, a first IP address after the first substream is canceled.
