Abstract

The invention discloses a VoWiFi business achieving method, system and an AAA server. The method comprises the steps that the EAP-AKA authentication requests initiated by UE are verified by the AAA server, if the verification is passed, a first authentication success information is returned to the UE and the EAP-AKA authorized authentication success information of the UE is saved; the IKE-Auther-Request information initiated by the UE is verified by the AAA server, if the EAP-AKA authorized authentication success information of the UE is saved in the AAA server, the verification is passed. The VoWiFi business achieving method, system and the AAA server can avoid the problem of a second time billing of the WiFi data stream and the VoWiFi voice data stream and the WiFi business stream passing through the P-GW device twice, through the saving of the EAP-AKA authorized authentication success information of a user on 3GPP-AAA at the time of crediting the WiFi access authentication, a second time EAP-AKA authentication is no longer needed when the S2b is being authenticated, and the time delay and the system computation amount at the authentication of the user are effectively reduced.

Description

technical field

[0001] The invention relates to the technical field of WIFI voice services, in particular to a method, system and AAA server for realizing VoWiFi services. Background technique

[0002] In the 3GPP standard, there are two schemes, S2a and S2b, for the integrated networking of WiFi and LTE. Among them, S2a is for trusted WiFi, and the general air interface uses encryption for public WiFi networks; while S2b is for non-trusted WiFi. Encrypt or use user-level encryption for private WiFi networks. At the beginning of the standard formulation, because the S2b scheme required terminals to support IPSce encapsulation of data streams, no terminal supported this scheme; with the launch of Apple IOS8, only VoWiFi (using WiFi to provide voice services) service data is supported for IPSec encapsulation , The terminal industry chain began to support the S2b solution. The S2b standard is mainly aimed at non-trusted WiFi networks. It does not define how to implement encry...
