Problems solved by technology

After the user revisits after hibernation, the AAA server will send a Radius Accounting Start packet to WAP, but the Beginning Session value is 0, so the WAP gateway does not think this is a new visit, so the WAP gateway accesses the database according to the "association identification number" User information in the database, but the user information in the database has been deleted at this time, because the user's access becomes anonymous because the user information cannot be queried

Embodiment Construction

[0032] In order to solve the anonymous access problem of the mobile terminal accessing the WAP gateway, the RadiusAccounting processing of the OMA specification is improved. In a common RADIUS message such as CSD (Circuit Switching), the user's online and offline can be identified by the Accounting Start and Accounting Stop messages of RADIUS respectively, and in the CDMA1x network, due to the existence of air link changes ( If the user is dormant), the WAP gateway will receive multiple AccountingStart and Accounting Stop messages during a WAP session. The RADIUS processing program of the WAP gateway must be able to effectively judge Radius Accounting in order to correctly judge the user's status.

[0033] When the WAP gateway receives the RADIUS Accounting Stop message, if the "SessionContinue" field is "1", it can be considered that the user's status has only changed, but the user has not gone offline; if the Session Continue field is "0", it can be considered When a user go...

Abstract

The present invention relates to a system used for solving visiting the WAP gateway disguisedly, comprising a mobile station, a wireless network, a packet switched data network, identification, authentication, a billing server and a WAP gateway, the started charging message sent by the packet switched data network to the identification, the authentication and the billing server includes association identifiers and a continuing of conversation, wherein the continuing of conversation is used for identifying the online or offline states of users; the identification, the authentication and the billing server transmit a starting charging packet and a stopping charging packet to the WAP gateway; after stopping interviewing the mobile station, the WAP gateway continues to judge whether to delete the calling party number and IP address information corresponding to the association identifiers from the data base or not according to the conversation. The present invention can solve effectively the cryptonym problem in the visits to the WAP gateway.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for solving anonymous access to a WAP gateway. Background technique [0002] The existing WAP gateway is not designed for the dormant state of CDMA1xRTT users, and cannot correctly handle the special Radius Accounting packets of CDMA1xRTT users when surfing the Internet, resulting in a large number of anonymous accesses after user dormancy / recovery. [0003] In the prior art, the brief process of WAP user accessing the Internet is as follows: [0004] In step 1, a mobile station (MS) initiates a connection request to a packet switched data network (PDSN) through a radio network (Radio Network). [0005] In step 2, the PDSN processes the request of the MS and sends it to an Authentication, Authorization, and Accounting (AAA) server for identity authentication and authentication. [0006] Step 3: After passing the authentication, the PDSN will assign an IP address to...
