Method and device for authentication and authorization checking on LBS in Wimax network
First Claim
1. A system for performing authentication and authorization checking on Location-Based Service (LBS) in a Worldwide interoperability for Microwave Access (WiMAX) network, the system comprisingan Access Service Network (ASN) comprising:
- a Location Agent (LA) adapted to perform location measurement; and
a Location Controller (LC) adapted to initiate LBS measurement, location calculation; and
a Connection Service Network (CSN) comprising;
an authentication and authorization information memory in an Authentication/Authorization/Accounting module (AAA);
an authentication processing module included in the AAA and responsible for authentication on a LBS service; and
an authorization checking processing module included in the AAA and responsible for authorization checking on a LBS client and a MS requesting for LBS.

Abstract
A device for performing authentication and authorization checking on Location-Based Service (LBS) in a WiMAX network is provided. This device strengthens security for LBS in a WiMAX network, and protects privacy right of subscribers to LBS. The device includes a Location Assessment module (LA) for performing the location assessment, a Location Coordination and control module (LC) for controlling LBS assessment and calculation of a location of a mobile terminal. The device also includes an Authentication/Authorization/Accounting module (AAA) that includes a memory storing authentication and authorization information. The AAA also includes an authentication processing module for authenticating an LBS, and an authorization checking processing module for checking whether an LBS client and a Mobile Station (MS) requesting services from the LBS are authorized to request the location of a target MS.

13. A method for successful authentication and authorization checking on Location-Based Service (LBS) in a Worldwide Interoperability for Microwave Access (WiMAX) network, the method comprising:
-
1) sending by a Location Server module (LS) an authentication and authorization checking request message to an Authentication/Authorization/Accounting module (AAA), is included in a Connection Service Network (CSN) after the LS receives a location request; 2) performing authentication and authorization checking in the AAA; 3) finding a serving Location Coordination and Control module (LC), which is included in an Access Service Network (ASN), for a MS if the authentication and authorization checking succeeds; 4) sending by the LS a location report request to the serving LC; 5) performing an intra-Access Service Network (intra-ASN) location determination process; 6) sending by the LC a location report response to the LS, with the response containing the obtained location of the MT MS; 7) sending by the LS a location response to the location requestor; and 8) sending by the LS updated accounting data to an accounting server. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A method for failed authentication and authorization checking on Location-Based Service (LBS) in a Worldwide Interoperability for Microwave Access (WiMAX) network, the method comprising:
-
1) Sending by LBS Client a Location Request to a Location Server module (LS), which is included in a Connection Service Network (CSN), in order to locate a Mobile Station (MS); 2) sending by the LS an authentication and authorization checking request to an Authentication/Authorization/Accounting module (AAA), which is included in the CSN, after the LS receives a location request; 3) performing authentication and authorization checking in the AAA; and 4) sending by the LS a location response to a location request initiator, if the authentication and authorization checking fails. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
