Integrated access method and system for mobile cellular network and WLAN

Abstract

The invention relates to a unified access method for mobile cellular network and radio local area network, comprising: step 1, setting a radio local area network authentication, authorization, charging server which is connected with a WAP gateway, a wireless controller respectively; step 2, a mobile terminal does a WAP registration to the radio local area network authentication, authorization, charging server; step 3, a radio local area network authentication of the mobile terminal is authenticated by the radio local area network authentication, authorization, charging server. The invention needs not rebuild PDSN (package data service node) of the CDMA1X network or SGSN / GGSN, WAP gateways of the GSM / GPRS network, keeps the package data service flow of the original mobile cellular network basically, does not change existing CDMA1X, CDMA1X service flow and net element functions, has high safety, centralized service flow, which is convenient to manage.

Description

technical field [0001] The invention relates to a mobile cellular network and a wireless local area network, in particular to a unified access method and system for the mobile cellular network and the wireless local area network. Background technique [0002] With the rapid development of wireless packet data services, the current mobile cellular network has been heavily loaded. For example, in hotspot areas, the average CDMA 1X Internet access speed has dropped to about 30-40k / s, which cannot meet the high-speed Internet access requirements of mobile terminals, especially in business areas with a high density of mobile terminals. The problem is even more serious. [0003] It is well known that wireless local area network (WLAN) technology can provide high bandwidth, but it is limited to a limited coverage area (in buildings and short distances outdoors). In contrast, mobile cellular networks such as CDMA 1X or GSM / GPRS support mobility across wide area networks, but the da...

Problems solved by technology

[0007] EAP-SIM and EAP-AKA authentication require user authentication information for WLAN authentication is obtained from HLR, currently the HLR of the current network does not support this function , the interface must be modified. If the implementation of the modification is difficult, it will have a great impact on the equipment running on the existing network, and the equipment modification standards of different manufacturers are not uniform, and the project investment is large. The current EAP technology and standards must support roaming. There is a lot to improve;

[0008] In addition, the EAP-SIM method and EAP-AKA authentication need to modify the user's mobile terminal, and both need to install third-party EAP software. For stock users, installation and maintenance work Huge amount;

[0009] "SMS + Web" authentication method is only the user password return using SMS to achieve, the authentication method has not achieved real integration

If the WLAN network is unstable, the frequency of frequent authentication will be high, which will reduce the user experience
