Method, equipment and system for enabling access points to access mobile core network

Abstract

The invention discloses a method for enabling access points to access a mobile core network, which comprises the following steps: establishing an IP network security protocol tunnel between security gateways by IP addresses of the security gateways; accessing an access gateway of the mobile core network by an IP address of the access gateway through the IP network security protocol tunnel; receiving the access of at least one access point; and transferring the access point to the access gateway of the mobile core network. An AP aggregation entity receives the access of a plurality of APs, accesses the AG of the mobile core network through an IPSec tunnel and transfers the APs to the AG of the mobile core network. Because of adding the AP aggregation entity, each AP is prevented from establishing the IPSec tunnel with SeGWs, and outlet bandwidth of a local area network is saved; and the APs simultaneously do not need to carry an SIM or USIM card so as to prevent each AP distributed to buildings of enterprises or schools from easily causing the problem of stealing the SIM or USIM card by people.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method, device and system for an access point to access a mobile core network. Background technique [0002] An access point (AP, Access Point) is a network device that provides wireless access services for homes, small offices, and home offices (SOHO, Small Office and Home Office) based on a fixed Internet Protocol (IP, Internet Protocol) transmission network. [0003] see figure 1 , which is a structural diagram of an AP applied to a home network. [0004] The user equipment (UE, User Equipment) accesses the AP through the air interface, and the AP accesses the IP transmission network through the home gateway (HGW, Home Gateway), and then connects to the security gateway (SeGW, Security Gateway) in the mobile core network through the IP transmission network , and then connect to the access gateway (AG, AccessGateway). The HGW can be integrated on the AP, and ...

AI Technical Summary

Problems solved by technology

Each AP needs to establish an IPSec tunnel through the enterprise gateway or campus gateway and the SeGW, resulting in multiple IPSec tunnels between the enterprise gateway or campus gateway and the SeGW, wasting the egress bandwidth of the enterprise gateway or campus gateway

Local calls and local data interaction between multiple APs or between APs and other devices must be implemented through AG transfer, which wastes mobile core network bandwidth and requires the use of mobile core network resources. Therefore, such local calls and local Data interaction is not free

In addition, the enterprise network or campus network needs AP networking to provide a large range of continuous coverage, and the switching function between APs is implemented by AG, which wastes mobile core network resources.

Since each AP has a SIM card or USIM card, and multiple APs are distributed in the buildings of enterprises or schools, it is easy to cause the SIM card or USIM card to be stolen, and there is no guarantee in terms of security.

[0008] It can be seen that when multiple APs of an enterprise or campus access the mobile core network through the enterprise gateway or campus gateway, not only the resources of the mobile core network are wasted, but also the SIM card or USIM card carried by each AP also has security issues.
