Description of drawings:
Fig. 1 is the first of the embodiment flow chart of the method for the invention;
Fig. 2 is the second portion of the embodiment flow chart of the method for the invention.
Embodiment:
The invention will be further described below in conjunction with accompanying drawing.
With reference to figure 1 and Fig. 2.Embodiment described in the figure is based on the connection of a digital TV subscriber management system (SMS is hereinafter to be referred as the SMS system) with two condition receiving systems (CA is hereinafter to be referred as the CA system).And these two CA systems, the SMS interface of CA system 1 and CA system 2 can be inequality to the call format of the authorization data that received.Use similar method can connect plural CA system, principle is identical.
Finish by CA system interface program in the operation reality of SMS system and two CA systems.Therefore, at first start the CA system interface program of SMS system in step 100, connect the SMS system database in step 105 then, it is different because of the kind of the employed database of SMS system, the title of database etc. that concrete database connects the parameter setting content, and concrete parameter value just should setting completed before connecting database; Next the whether successful connection in step 107 judgment data storehouse, if cause connection failure because parameter is provided with reasons such as problem or the connection of database refusal, EP (end of program) then, if the database successful connection shows the authorization data that can normally retrieve in the SMS system, and can enter follow-up normal running.
It is corresponding with it then to create a socket (Sockets) example in step 110 at the SMS interface of each CA system, the corresponding CA of example a system 1 in this example, the corresponding CA of example b system 2.After example is created, will connect with corresponding CA system respectively in step 115.Procotol in this example adopts connection-oriented Transmission Control Protocol, also can adopt User Datagram Protoco (UDP) (udp protocol) in the reality, connects IP address, receiving port number that parameter comprises the SMS interface of the pairing CA of each Sockets example system.Judge whether successful connection of network in step 117 then,, illustrate that network has certain fault, EP (end of program) if all fail to be connected with the SMS interface of two CA systems.If only successful connection one of them, illustrated that other CA system does not connect on, so the failure of function implementation procedure is also regarded in this single connection as, need other troubleshooting, EP (end of program).If all successful connections of SMS interface of program and two CA systems then enter follow-up operation.
Next create a timer object (Timer) example in step 120, the time interval according to setting, be assumed to be 30 seconds in this example, start the timer example, program can activate the processing procedure of an authorization data every 30 seconds.When not having interarrival time point, program is in wait state in step 130 always, and judges whether to arrive the dot interlace of fixing time automatically in step 140, if do not arrive, then program can continue to wait for.Program arrives the dot interlace of fixing time after waiting for 30 seconds, timer can activate next step action automatically.When next one action arrived, at first whether the program authorization data treatment progress that can once activate on step 150 is judged finished, if also do not finish, program can continue to wait by the time next time interval point activate processing procedure once more in step 130.If the process that the last authorization data that activates is handled finishes, illustrate to be connected to be in idle condition, so just can send the authorization data that was activated to this authorization data that is produced in activating during this period of time last time and needed to retransmit to corresponding CA system with the network of the SMS of CA system interface.
Next program need be retrieved the SMS system database, searches successively and is activated to this user authorization data that belongs to CA system 1 and CA system 2 that produces in activating during this period of time and the authorization data of needs repeating transmission in last time.Whether search in step 160 earlier has the user authorization data that belongs to CA system 1 to need to send, if the SMS system did not did not accept the customer service that belongs to CA system 1 during this period, and the user authorization data that does not belong to CA system 1 need resend, explanation does not need to send authorization data to CA system 1 in current the activation, and whether therefore continue to search in step 170 has the user authorization data that belongs to CA system 2 to need to send.If there is the user authorization data that belongs to CA system 1 to need to send, for example: the SMS system has accepted the request of the user A ordering services that belongs to CA system 1 in the stand-by period before current the activation, program at first can extract the authorization data at user A in step 163 from the SMS system database, give Sockets example a then, be connected by the TCP between the SMS interface of a and CA system 1, the data format that can receive according to the SMS interface of CA system 1 in step 165 sends to this part authorization data the SMS interface of CA system 1.In step 167, the CA system receives the authorization data at user A, utilize these data to generate Entitlement Management Message and send to user side, change authorization attribute, give the right that user A receives the business of being ordered, and the SMS interface of CA system can feed back to the result of authorization data Sockets example a, after example a receives the feedback information of CA system, whether the authorization data that just can understand at user A is successfully received and handles by the CA system, again will be about the authorisation process outcome record of user A in the SMS system database.If the feedback information of CA system is represented the authorization data of user A and is successfully received by it and be correspondingly processed, program just can be in the SMS system database marks this part authorization data of user A, during expression activation next time authorization data transmission and processing process, these data do not need to send again.If the feedback information of CA system is represented this part authorization data and takes defeat or handle and make mistakes that program is not carried out mark to these authorization datas, so that wait by the time resend when activating next time.
Sending the authorization data that belongs to CA system 1, whether have the user authorization data that belong to CA system 2 need send, if do not have, illustrate that the authorization data of two CA systems in this activates all disposes if next continuing to search in step 170.If there is the user authorization data that belongs to CA system 2 to need to send, the similar process of the user authorization data of concrete processing procedure and processing CA system 1, promptly at first extract those and belong to the authorization data of CA system 2 in step 173, give the SMS interface that Sockets example b sends to CA system 2 in step 175 with these data then,, according to the process information that CA system 2 feeds back data processed result is recorded in the SMS system database at step 177Sockets example b at these authorization datas.At this moment, the authorization data of CA system 1 and CA system 2 all disposes, can select whether to stop timer as required in step 190, if do not stop, change step 130, program is waited for the arrival of the next dot interlace of fixing time, so that activate the process of handling next group CA system authorization data once more automatically.If stop timer, then be connected with the TCP of two CA systems in step 200 disconnection, finish then.
According to foregoing, the present invention can realize that a SMS system manages the user who belongs under a plurality of CA system simultaneously, and by the CA system interface Automatic Program of SMS, user authorization data is sent to corresponding C A system in real time, reach the purpose of all user watched power in the control compass of competency.
