1. A method for accessing a heterogeneous network via a Wireless Local Area Network (WLAN), the method comprising:
- receiving, by an authentication serving gateway, an access request from a server, wherein the access request includes information relating to a target network that a terminal needs to access via the WLAN, wherein the heterogeneous network is the target network;
determining, by the authentication serving gateway, the target network that the terminal needs to access according to the access request from the server, wherein a transmission protocol of the target network is different from that of the WLAN;
converting, by the authentication serving gateway, the access request according to the transmission protocol of the target network;
sending, by the authentication serving gateway, the converted access request to the target network;
receiving, by the authentication serving gateway, an authentication result from the target network; and
sending, by the authentication serving gateway, the authentication result to the server;
wherein the access request from the server carries an access policy; and
wherein the determining the target network that the terminal needs to access comprises determining the target network that the terminal needs to access according to the access policy in the access request.

Abstract
A method and an apparatus for accessing heterogeneous networks via a Wireless Local Area Network (WLAN) are disclosed. The method includes receiving an access request from a WLAN terminal or a portal/policy server; determining a target network that the terminal needs to access according to the access request; converting the access request according to the format of a target network transmission protocol; sending the converted access request to the target network; and receiving an authentication result from the target network, and sending the authentication result to the terminal.

9. A server, comprising:
-
an access request receiving unit, adapted to receive an access request from a terminal; a login page sending unit, adapted to send an authentication login page to the terminal when the access request is received from the terminal; a login information receiving unit, adapted to receive authentication login information from the terminal; an access request sending unit, adapted to determine an access policy according to the authentication login information and send a second access request that comprises the access policy to an authentication serving gateway to determine a target network that the terminal needs to access via a Wireless Local Area Network (WLAN); and an authentication result receiving unit, adapted to receive an authentication result from the authentication serving gateway; wherein a transmission protocol of the target network is different from that of the WLAN; and wherein the server comprises a policy server or a portal server. - View Dependent Claims (10)
