Network handover method, apparatus, device, and system
First Claim
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 when the control node determines that the first state information and the second state information meet a preset first handover condition, wherein the WLAN AP belongs to a wireless local area network (WLAN), and wherein the handover node and the control node are network-side nodes;
attaching, by the UE, to the cellular network indicated by the first handover command;
receiving, by the UE, an Internet Protocol (IP) address of the UE in the cellular network, and implementing a handover from the WLAN to the cellular network; and
adding a UE identity into radio resource control (RRC) information and sending the RRC information to the control node, or receiving an identity request sent by the control node and feeding back the UE identity to the control node according to the identity request.

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.

4. A method, comprising:
-
acquiring, by a control node, first state information of a wireless local area network access point (WLAN AP) corresponding to a location of user equipment (UE) and second state information of a cellular network that the UE accesses, wherein the control node is a network-side node; in response to determining that the first state information and the second state information meet a preset second handover condition, generating, by the control node, second handover information, wherein generating the second handover information comprises; acquiring a UE identity, an identifier of the WLAN AP, and a packet data network (PDN) identity; and adding the UE identity, the identifier of the WLAN AP, and the PDN identity into the second handover information, wherein the UE identity and the PDN identity are used to generate notification information; and instructing, by the control node, a preset node to send, to the UE, a second handover command that is generated according to the identifier of the WLAN AP, so that the UE accesses the WLAN AP indicated by the second handover command, receives an Internet Protocol (IP) address of the UE in a WLAN, and implements a handover from the cellular network to the WLAN. - View Dependent Claims (5, 6)
