Embodiment Construction

[0051] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction of related technologies of the present application is given as follows.

[0052] First, Media Independent Handover (MIH, Media Independence Handover) technology:

[0053] MIH technology is a method to provide link layer information and other related network information to the upper layer. This technology can be used for switching between heterogeneous networks. Among them, by adding an independent MIH layer between the second layer (data link layer) and the third layer (network layer), the information of the data link layer can be obtained, so as to achieve the purpose of triggering the handover between heterogeneous networks in advance. For example, the link layer information may include, for example, the transmission behavior of a Layer 2 data link.

[0054] The types of services provided by MIH include:

[0055] (1) Event service

Abstract

The embodiment of the present application provides an application data migration method and a network device, which can provide an optimal communication path for old application data after the terminal device moves. The method includes: the network device acquires a first parameter, a second parameter and a third parameter, wherein the first parameter includes a time delay for communicating between the terminal device and the first server through the first connection, and the second parameter includes the communication delay between the terminal device and the second server. The delay of the server communicating through the second connection, the third parameter includes the synchronization context time between the first server and the second server; if the first parameter is greater than the second parameter and the third parameter sum, the network device determines that the application data on the terminal device needs to be migrated from the first connection to the second connection; if the first parameter is not greater than the second parameter and the third The network device determines that the application data does not need to be migrated from the first connection to the second connection.

Description

technical field [0001] The present application relates to the technical field of wireless communication, in particular to an application data migration method and network equipment. Background technique [0002] Currently, when a terminal device moves, the terminal device may need to establish a new communication path, so that data of a new application on the terminal device can be transmitted through the communication path. As for the data of the old application before the terminal device is moved, the terminal device migrates the data of the old application to the new communication path uniformly, or uniformly retains the data of the old application on the original communication path. For example, if figure 1 As shown, before the terminal device moves, the domain name A is accessed, and the domain name resolution system (domain name system, DNS) server resolves the domain name A to an Internet protocol (internet protocol, IP) address IP1 and returns it to the terminal dev...
