Abstract
The invention provides a kind of method of scheduling user authorization information, belong to digital TV field.Adopt the database storage authorized user message to cause system's instability, low performance and inflexible problem in order to solve existing cas system, the invention provides a kind of method of scheduling user authorization information, may further comprise the steps: authorized user message is stored in the database; Organize authorized user message to generate the Entitlement Management Message data, store in another database; And be stored in the hard disk of condition visitation system.The present invention finishes the storage of authorized user message by multi-stage scheduling, has improved the efficient and the reliability of cas system operation, can easily manage millions of users; And the degree of coupling between the scheduling at different levels is very low, and influence each other is very little; By the mechanism of hard disk and internal memory stores synchronized and renewal EMM data, the flexibility that has improved subscriber authorisation efficient and system.
Description
Technical field
The present invention relates to digital TV field, particularly a kind of method of scheduling user authorization information.
Background technology
Along with the popularization of Digital Television in China, the user that Digital Television need be managed is more and more, also requires more and more higher to the efficient of CAS (ConditionalAccess System, condition visitation system), the performance of simultaneity factor, stability and flexibility also become the important evaluation criterion of system.For the authorized user of CAS, require the short as far as possible mandate time, and wish that cas system can meet the demands as much as possible on fault-tolerance and unsteadiness.Referring to Fig. 1, in most of cas systems, be responsible for finishing all users' licensing process by EMMG (Entitlement Management Message Generator, EMM Generator), comprise the tissue of authorization message and memory scheduling etc.The user is by SMS (SubscriberManagement System, Subscriber Management System) input original user authorization message, tissue is meant to be handled the original user authorization message, finally become EMM (Entitlement Management Message, Entitlement Management Message) data, i.e. user's the top box of digital machine data that can receive.EMMG adopts database to store authorized user message and related data usually, but can cause system following problem to occur:
1, instability: the arbitrary process in subscriber authorisation process, subscriber authorisation organizational process, subscriber authorisation process of transmitting or user authorization data storing process goes wrong, all can influence the operation of cas system, even need restart whole system, caused the very big unsteadiness of system;
2, low performance:, when the needs tissue, read or when sending authorization message, all need database is operated accordingly, greatly reduced efficient because user's authorization message is stored in the database;
3, dumb: all users' authorization message all is stored in the database, when authorized user message increases when reaching a certain amount of, if wish according to priority not or, just need do bigger change to database by the layer management authorization message, be difficult for realizing, therefore reduced the flexibility of system.
Summary of the invention
Adopt the database storage authorized user message to cause system's instability, low performance and inflexible problem in order to solve existing cas system, the invention provides a kind of method of scheduling user authorization information, specifically may further comprise the steps:
Steps A: authorized user message is stored in the database;
Step B: organize described authorized user message to generate the Entitlement Management Message data, with described Entitlement Management Message storage in another database;
Step C: in the hard disk of CAS, described CAS is a condition visitation system with described Entitlement Management Message storage.
Described method also comprises:
When described Entitlement Management Message storage is in the hard disk of described CAS, with described Entitlement Management Message storage in the internal memory of described CAS; And the transmission priority height of the Entitlement Management Message data in the described hard disk of transmission priority ratio of the Entitlement Management Message data in the described internal memory is set.
Described method also comprises:
After generating described Entitlement Management Message data, described Entitlement Management Message data are encrypted, data encrypted is stored in the hard disk of described CAS.
Described method also comprises:
When described data encrypted being stored in the hard disk of described CAS, described data encrypted is stored in the internal memory of described CAS; And the transmission priority height of data encrypted in the described hard disk of transmission priority ratio of data encrypted in the described internal memory is set.
The present invention finishes the storage of authorized user message by multi-stage scheduling, has improved the efficient and the reliability of cas system operation, can easily manage millions of users; And the degree of coupling between the scheduling at different levels is very low, and influence each other is very little; By the mechanism of hard disk and internal memory stores synchronized and renewal EMM data, the flexibility that has improved subscriber authorisation efficient and system.

Fig. 1 is the schematic diagram of existing cas system dispatched users authorization message;
Fig. 2 is the schematic diagram of embodiment of the invention scheduling user authorization information;
Fig. 3 is the method flow diagram of embodiment of the invention scheduling user authorization information.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments, but the present invention is not limited to the following examples.
The embodiment of the invention is carried out three grades of caching mechanisms to user authorization data, and the priority scheduling algorithm is provided.At first with the deposit data of subscriber authorisation in a database, form basic authorized user message, as the first order storage of data; Authorized user message is organized, formed the EMM data message, and leave in another database, as the second level storage of data; The EMM data message is encrypted, the form of data encrypted with file is stored in the hard disk of cas system, and by carrying out data management based on distinctive priority scheduling mechanism, as the third level storage of data.
Referring to Fig. 2 and Fig. 3, the embodiment of the invention provides a kind of method of scheduling user authorization information, specifically may further comprise the steps:
Step 101: authorized user message is stored in the database, carry out first order storage; Can adopt front-end WEB (World Wide Web) method of service during storage, promptly on the interactive interface of server, import authorized user message;
Step 102: organize authorized user message to generate the EMM data, i.e. top box of digital machine data that can receive, and with the EMM storage in the another one database, carry out second level storage; The database of storage EMM data and the database of storage authorized user message are separate, are independent of each other;
Step 103: the EMM data are encrypted, the form of data encrypted with file is stored in the hard disk of cas system, the form with data is stored in the internal memory of system simultaneously, carries out third level storage;
The priority height of file in the priority ratio hard disk of data in EMS memory is set, when sending authorized user message to the user, according to the order of priority, preferentially the data with internal memory send to the user, and the speed that sends again than the file that reads in the hard disk is a lot of soon like this; And the data in the internal memory and the file in the hard disk be to upgrade synchronously, do not influence the performance of system.
In the said process, even first order storage and second level storage take place unusual and cisco unity malfunction, third level storage can be not influenced yet, can guarantee that authorized user message can normally send in user's the set-top box.
Above-described embodiment is a more preferably embodiment of the present invention, and common variation that those skilled in the art carries out in the technical solution of the present invention scope and replacement all should be included in protection scope of the present invention.
