METHOD AND SYSTEM FOR ORDER RELATIONSHIP AUTHENTICATION, AND MOBILE MULTIMEDIA BROADCASTING-CONDITIONAL ACCESS SYSTEM

摘要

An order relationship authentication method includes the steps that a Mobile Multimedia Broadcasting-Conditional Access System (MMB-CAS) at a visiting location obtains operation and management information from a Service Operating Support System (BOSS) corresponding to the MMB-CAS at the visiting location; the MMB-CAS at the visiting location receives a request message for obtaining a service key by a user, and triggers an order relationship authentication; the MMB-CAS at the visiting location requests an MMB-CAS at a home location to perform the order relationship authentication on the user; and the MMB-CAS at the visiting location receives an authentication result of the order relationship of the user feedbacked by the MMB-CAS at the home location and performs corresponding disposals. The present invention also provides an order relationship authentication system and a Mobile Multimedia Broadcasting-Conditional Access System. The present invention can reduce the synchronization data quantity between the MMB-CASs, and improve the overall performance and reliability of the system.
