Method of accessing and quitting network and sending messages and network side equipment

Abstract

The invention discloses a method of accessing and quitting a network and sending messages and network side equipment. The method comprises the following steps: after receiving messages of requests of the user for accessing, a router accessed a server distributing private web addresses for users, sending the private web addresses to user equipment, building up accessing dialogues, and allocating dialogue identifications for accessed dialogues; the router accessed to the server inquiring identification labels of the user equipment, building up associated relationship information of the identification labels and the dialogue labels of accessed dialogues; locating the user equipment through the associated relationship information of the identification labels and the dialogue labels of the accessed dialogues at time of sending uplink messages and downlink messages. Consequently, the method and the network side equipment can distribute the same private web address for different user equipment and solves the problem of address collisions caused when different user equipment uses the same private web address.

Description

technical field [0001] The invention relates to the field of mobile communication and the Internet, in particular to a method for accessing and exiting a network and sending messages and a network side device. Background technique [0002] In the Internet Protocol Version 4 (IPV4) network, due to the shortage of IPV4 address resources, it is generally not possible to assign a unique IPV4 public network address to each user, such as figure 1 As shown, most of them are assigned to users' private network addresses. The access router performs network port address translation (NAPT) on user addresses and port numbers, or NAT A+P processing, and multiple users share a public network address. Internet use. [0003] For fixed users, generally the number of fixed users carried by one access router is not very large, the number of IPV4 private network addresses is enough for users under one access router, and users under different access routers can use the same IPV4 private network ...

AI Technical Summary

Problems solved by technology

In this way, the IPV4 private network addresses of users under different access routers cannot be the same, otherwise, address conflicts will occur after users move to a new access router

In addition, if different IPV4 private network addresses are assigned to all users connected to the router in the network, because the number of users on the mobile Internet is very large, the number of IPV4 private network addresses will not be sufficient.

[0004] Therefore, in the mobile Internet, it is necessary to find a method that allows IPV4 users to access the network and use services normally, and keep the address unchanged when the user is moving, so as not to conflict with the address of the user in the newly accessed access router. method, or need to solve the problem of assigning different IPV4 private network addresses to all users, but the addresses are not enough
