A method and device for self-adaptation between public network and private network

Abstract

The invention discloses a public network and private network self-adapting method and device. The method comprises the steps of when a private network is congested, selected part of terminals is disconnected; a private network broadcast identifier is modified and private network access forbidding information is set in the broadcast identifier; the public network sends a load search request to the private network according to a preset cycle; the private network receives the load search request, searches network load and judges whether the network load is smaller than a preset load threshold value or not; if the network load is smaller than the preset load threshold value, a congestion removal instruction is fed back to the public network, the private network broadcast identifier is modified and private network access allowed information is set in the broadcast identifier; and the public network receives the congestion removal instruction sent by the private network, disconnects connected terminals according to the information in the congestion removal instruction and enables the terminals to be connected with the private network again. According to the public network and private network self-adapting method and device, the congestion problem of the public network can be effectively solved, and when the congestion of the private network is removed, the terminals in the public network can return to the private network.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for self-adaptation between a public network and a private network. Background technique [0002] The network has increasingly become an indispensable part of people's production and life. In order to meet the diverse needs of use, at present, in some special fields, independent communities or special department units, dedicated networks (dedicated networks for short) are often set up at the same time. network) and shared network (referred to as the public network). When the public network and the private network exist at the same time, it is necessary to determine which network the terminal should access. Generally speaking, in these areas, based on factors such as security, terminals should mainly work on private networks. However, for the current wireless network, the resources of the private network are relatively scarce. Therefore, too man...

Problems solved by technology

In this way, not only the operation is troublesome, but also the randomness is large, which cannot guarantee to solve the problem of private network congestion

Moreover, when the private network becomes unobstructed, the terminals in the public network cannot automatically switch to the private network. Although these terminals can return to the private network by shutting down and restarting, if the private network is still congested at this time, it will lead to returning to the private network. At the same time, during the shutdown and restart period, the terminal cannot perform related business operations, which greatly affects the user's use and experience

[0004] On the other hand, when the private network is congested, the private network cannot prevent new user terminals from trying to access the private network. The efficiency of connecting the terminal to the private network is low and greatly affects the user experience of the end user

[0005] Therefore, in the process of implementing the present invention, the inventor found that the prior art has at least the following problems: when the existing network system is equipped with private network and public network at the same time, not only cannot effectively solve the congestion problem of the private network, but also when the private network is restored , the terminals in the public network cannot be returned to the private network in time
