Handover method and system in master-slave network, master device, and slave device
First Claim
1. A handover method in a master-slave network, the method comprising:
- determining, by a master device of the master-slave network, that a user device needs to be handed over from an access device, wherein the master-slave network comprises the master device, a first slave device, a second slave device, and the user device, and wherein the first slave device is the access device of the user device;
determining, by the master device, that the user device is to be handed over to the second slave device;
sending, by the master device to the second slave device, a first identifier of a first network interface and a second identifier of the user device, wherein the first identifier and the second identifier are received by the master device from the first slave device, wherein the sending the first identifier and the second identifier to the second slave device causes the second slave device to allocate a second network interface to the user device, wherein a third identifier of the second network interface is the same as the first identifier of the first network interface, wherein the first network interface is a network interface allocated by the first slave device to the user device and used when the user device accesses the first slave device, and wherein the second identifier of the user device and the first identifier of the first network interface correspond on a one-to-one basis;
instructing, by the master device, the first slave device to send first network connection information to the second slave device, wherein the first network connection information is information associated with a first connection established between the user device and the first network interface of the first slave device, wherein the first slave device sending the first network connection information to the second slave device causes the second slave device to generate second network connection information using the first network connection information, wherein the second network connection information is network connection information associated with a second connection between the user device and the second network interface of the second slave device;
sending, by the master device, a first handover command to the first slave device, wherein the first handover command enables the first slave device to deactivate the first network interface; and
sending a second handover command to the second slave device, wherein the second handover command enables the second slave device to activate the second network interface.

Abstract
A handover method in a master-slave network, and a master device, and slave devices are provided. The method includes when a master device or a first slave device determines that a user device needs to be handed over to a second slave device, the first slave device sends, to the second slave device, a first identifier of a first network interface allocated by the first slave device to the user device, and first network connection information used after the user device establishes a connection to the first network interface of the first slave device. The first identifier of the first network interface and a second identifier of the user device correspond on a one-to-one basis. The first slave device deactivates the first network interface and the second slave device activates a second network interface.
