Network Handover Method, Apparatus, Device, and System

摘要

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.

1. A method, comprising:
receiving, by a user equipment (UE), a first handover command that is generated according to first handover information by a handover node, wherein the first handover information is generated when a control node acquires first state information of a wireless local area network access point (WLAN AP) that the UE accesses and second state information of a cellular network corresponding to a location of the UE and it is determined that the first state information and the second state information meet a preset first handover condition; attaching to the cellular network indicated by the first handover command; and receiving an Internet Protocol (IP) address of the UE in the cellular network, and implementing a handover from the WLAN to the cellular network.
