Network access method and system

Abstract

The invention provides a network access method and system. The method comprises the following steps: accessing internet cards of a plurality of service providers so as to simultaneously access a plurality of service provider networks, and obtaining distributed bandwidths, signal intensities and / or network delays of target hosts of the service provider networks when a network connection request from a terminal is received; sorting the service provider networks according to the distributed bandwidths, signal intensities and / or network delays of target hosts of the service provider networks, and selecting one optimal service provider network; storing the next hop IP addresses of the service provider networks in a connection table, and enabling the terminal to access the selected optimal service provider network according to the IP address so as to connect with the target host. The wireless network accesses of the plurality of service providers can be simultaneously supported so that each network connection can get the optimal access form. The speed of users accessing the network can be accelerated without increases in expenditure.

Description

Technical field [0001] The invention belongs to the field of mobile communication and Internet Protocol (Internet Protocol, IP) core networks, and particularly relates to a network access method and system. Background technique [0002] In order to increase the Internet speed of end users of wireless networks, operators and industries are constantly improving their respective networks. The main improvements include the following: [0003] 1. Diversion between 3G network and WIFI network within the same operator [0004] Operators deploy tens of thousands of WIFI nodes in hotspot cities and regions, allowing users to seamlessly switch between 3G networks and WIFI networks. [0005] Seamless switching is not yet mature, and manual switching is the main method. However, the user needs to disconnect all current connections manually to switch, and the mobility is poor. Moreover, each city needs to build tens of thousands of WIFI hotspots, which is costly. [0006] 2. The same operator's ...

AI Technical Summary

Problems solved by technology

However, manual switching by the user requires disconnection of all current connections, resulting in poor mobility

Moreover, tens of thousands of WIFI hotspots need to be built in each city, and the cost is relatively high

[0006] 2. The internal traffic of the same operator is busy or idle

[0012] The method of increasing the Internet access speed of wireless network terminal users in the prior art is aimed at the situation that wireless Internet access only supports the network access of a single operator, and does not involve the situation that wireless Internet access supports multiple operator networks
