Method and apparatus for locating business authentication and authorization examination in Winax network

Abstract

The invention provides a device of location business certification and authorization check in Wimax network, comprising: a measurement module LA used for location measurement; a location coordination and control module LC used for starting LBS measurement, and for location calculation; a memory for storing LBS signing information in AAA; a certification process module contained in AAA for certifying LBS business; an authorization list memory contained in LS; and an authorization check module in LS for authorization checking MO MS. The invention provides a method for certifying and authorization checking location businesses in Wimax network, which strengthens security of location businesses in Wimax network to a great extend, ensures privacy of users signing LBS and makes up corresponding blanks in current Wimax standard.

Description

technical field [0001] The present invention relates to a method and device for authenticating and authorizing a Location Based Service (LBS) in a Worldwide Interoperability for Microwave Access (Wimax) network. Background technique [0002] The third generation partnership project (hereinafter referred to as 3GPP) technical specifications 3GPP TS 22.071 and 3GPP TS 23.271 stipulate the mechanism of confidentiality check for LBS service in wideband code division multiple access (hereinafter referred to as WCDMA) network. Among them, it is stipulated that the modules related to the privacy check include: [0003] (1) Privacy Profile Register (Privacy Profile Register, hereinafter referred to as PPR) [0004] The main function of PPR is to realize the privacy check. The home location register (hereinafter referred to as HLR) or the home subscriber server (hereinafter referred to as HSS) saves the address of the PPR, and the home mobile location center (hereinafter referred to...

AI Technical Summary

Problems solved by technology

[0033] (2) The privacy checking mechanism of LBS in 3GPP is obscure and difficult to understand, and the practicability is poor.

[0034] (3) The privacy check mechanism of LBS in 3GPP is relatively complicated

[0035] The privacy check mechanism in 3GPP is relatively comprehensive, such as specifying two separate entities PPR and PMD to handle privacy checks, using pseudonyms, etc., but the problems that follow are complex

This is also not in line with the simple and practical principle of Wimax network

[0036] (4) The LBS privacy check mechanism in 3GPP leaves too much space for operators. If operators want to use LBS privacy check, they need to design many mechanisms on the basis of 3GPP related specifications, such as the most important The use of codewords, how to generate and distribute codewords, how to check, etc., all need to be designed by operators. In addition, although 3GPP stipulates that pseudocodes can be used, the functions of PMD also need to be defined by operators
