Problems solved by technology

[0008] The switching that occurs in the above way will cause a long period of network interruption and affect the user's service experience
In the basic Mobile IP, the data communication interruption time is too long, the essential reason is that the network layer is not sensitive to the change of the underlying link environment
[0009] In addition, when the user is in an overlapping coverage area, it may be impossible to accurately determine which target handover cell or target handover routing area should be handed over to, thus causing ping-pong handover, or forcing the user to handover behavior when the user should stay in the original coverage area. Phenomenon that affects user service experience

[0069] The embodiment of the present invention provides a method for network layer switching, see figure 2 , the method includes:

[0070] S201. Acquire a movement track of a terminal and a trigger message reflecting a link state.

[0071] Wherein, the above-mentioned trigger message is one or more messages, which may reflect a current event or state of the underlying link. For example, the trigger message may include a message indicating that the current link is about to be disconnected, and may also include a message indicating that the current link is about to be disconnected. The message that the conversion between the road and the new link is completed. By obtaining the trigger message, the terminal can perceive the state change of the underlying link and the handover event in time, so as to prepare for the handover of the network layer.

[0072] Wherein, the movement trajectory of the terminal can be predicted according to the current network coverage and road conditi...

Abstract

The invention provides a method and apparatus for switching a network layer and relates to the technical field of communication. The method includes the following steps: acquiring motion track of a terminal and a triggering message which reflects link state; and on the basis of the acquired motion track and the triggering message, switching the network layer. According to the invention, the technical solution can make accurate determination on switching in combination with the motion track of the terminal, increases switching accuracy, senses state and event of a bottom layer in an in-time manner by acquiring the triggering message, switches the network layer swiftly, and reduces disconnection length of data communication.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for network layer switching. Background technique [0002] For the basic Mobile IP (Mobile IP) protocol, the duration of data communication interruption caused by network layer switching includes four parts, see figure 1 . [0003] 1.T Layer-2 (Layer 2 link switching time): Because in basic Mobile IP, mobility detection occurs after the layer 2 link switching is completed. The so-called layer-2 link conversion refers to the conversion of a mobile node (Mobile Node, MN for short) layer-2 access point, such as the conversion of an access point in a WLAN. In single-mode switching at the network layer, switching at Layer 2 will cause interruption of data communication. Compared with the concept of Layer 2 handover, network layer handover is called "Layer 3 handover". [0004] 2.T DETECT (mobility detection time): T DETECT The size of is determined by...
