Access to Service 3 PDSN AAA CSG Service 1 Service 2: Local Multimedia Service 3 Stock Quotes QS BMA GET( ? The user requests a stock quote, which matches Service 3. CSG has not authorized the user for Service 3 yet. SvcAuthReq ? CSG Sends SvcAuthReq(UserName, Service 3) to QS. Service 3 is billed per download, so the quota server deducts money (say, another €1) from the user’s account which will allow 10 downloads. SvcAuthRsp ? QS sends SvcAuthResp(UserName, service2, 10) to CSG, which allows the user 10 downloads in service 3 ? CSG forwards the request to the content server, and the user gets the quote. CSG now has sufficient quota for another 9 stock quotes. 40 169。 2022 Cisco Systems, Inc. All rights reserved. First Service Access (Service 2)
