Description
Technical field
The present invention relates to the digital television techniques field, relate in particular to the method and system that a kind of authorization message sends.
Background technology
Our country is in the concentrated promotional period and the growth stage of Digital Television at present, since historical reasons, the digital scrambling-descrambling technology that all is based on the unidirectional condition receiving system that most of operator adopts.
In the unidirectional condition receiving system, be to adopt to set-top box transmission authorization message to realize the leading subscriber subscribed services.In order effectively to utilize the cable TV network bandwidth resources, and as much as possible authorization message is sent to set-top box, send characteristics according to TV audient business characteristic (comprise order, hand over money, send out phenomenons such as mandate may all can occur focusing on a large scale) and CA, each radio and television users management system adds mandate generally can adopt two kinds of delegated strategies: the long mandate and short mandate.Quit the subscription of under the situation in user's transact services, then transmission subtracts mandate to stop service.
Wherein long the mandate is to show the subscriber computer top box to send out the authorization message that adds that a Close Date surpasses its subscribed services Close Date.Opposite extreme situations is exactly to send out the authorization message that adds of a no Close Date, at expire-services or send out one end of service day again and subtract authorization message.
The short mandate is to show the authorization message that adds that the subscriber computer top box is sent out a short-term.The Close Date of general authority information is the Close Date of subscribed services, at this moment, owing to specified the mandate Close Date, if do not suspend or stop professionally midway, does not then need to send out again and subtracts authorization message and go to stop service.
Subtract to authorize and be meant and the authorization message that can allow set-top box stop respective service immediately sometimes be also referred to as anti-mandate.
In unidirectional CA system, can successfully receive the Conditional Access authorization message in order to guarantee set-top box, each tame CA system of industry all has specific authorized information to send strategy.These strategies generally all can be followed such rule: system can repeatedly send same authorization message, and generally all be blanking time between each the transmission tight at first but afterwards loose.Authorization message to a customer group, system can repeatedly send to customer group in a period of time, each is taken turns and can carry out the transmission of next round authorization message at once after authorization message sends, and according to principle tight at first but afterwards loose, former transmissions of taking turns authorization message are shorter at interval, the transmission of later several rounds authorization message is more and more longer blanking time, and transmission frequency is more and more lower.
The subscriber computer top box generally can be received authorization message more timely in the higher time period of authorization message transmission frequency; And, need the long time can receive authorization message in the lower time period of transmission frequency.Do not add mandate if the subscriber computer top box is received in during authorization message sends, the user can't watch program; Subtract mandate if can not receive, then the user just can watch program always, till the Close Date of setting in corresponding authorization message.
In the unidirectional condition receiving system, set-top box is the various authorization messages and the video stream signal of receiving front-end transmission passively.Owing to there is not return path, can receive authorization message in order to make set-top box, generally be repeatedly to send authorization message by headend equipment to solve.
Simultaneously,, order at a large number of users under the emergency case of program, authorization message is progressively overstock and can not in time send because the unidirectional condition receiving system needs one by one, in turn each user sends authorization message in customer group.
Above-mentioned two kinds of phenomenons can exist in the unidirectional condition receiving system simultaneously; the stack of two kinds of phenomenons can make systematic function sharply descend; usually can cause or set-top box can not receive and adds authorization message and cause customer complaint; be exactly that set-top box can not receive and subtracts authorization message and cause the program can't fair termination, under extreme case even systemic breakdown can occur.
Summary of the invention
The objective of the invention is to propose the method and system that a kind of authorization message sends, can effectively reduce the authorization message traffic volume, reduce authorization message and send density, thereby reduce the user because set-top box fails in time to receive authorization of service or stop authorization of service, and can't normally use the phenomenon of corresponding service or operator's loss.
For reaching this purpose, the present invention by the following technical solutions:

Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by embodiment.
Fig. 1 is the structural representation of authorization message transmitting system in the specific embodiment of the invention.As shown in Figure 1, this authorization message transmitting system comprises Subscriber Management System 10, Conditional Access authorization message pretreatment module 20, Service Database 30, conditional access system 40 and set-top box 50.
Fig. 2 is the structural representation of Conditional Access authorization message pretreatment module in the authorization message transmitting system in the specific embodiment of the invention.As shown in Figure 2, wherein Conditional Access authorization message pretreatment module 20 further comprises delegated strategy library unit 204, conditional access system characteristic parameter generation unit 201, user characteristics parameter generating unit 202, broadcasting and TV operation policing parameter generation unit 203 and Conditional Access authorization message generation unit 205.
Conditional access system characteristic parameter generation unit, user characteristics parameter generating unit and broadcasting and TV operation policing parameter generation unit send to the delegated strategy library unit with conditional access system characteristic parameter, user characteristics parameter and broadcasting and TV operation policing parameter respectively, and the delegated strategy library unit produces the strategy of authorization message.
Wherein, the system features parameter of having ready conditions comprises parameters such as authorization message transmission frequency; The user characteristics parameter comprises parameters such as credit rating, user type, discount; The business of quitting the subscription of can not be handled in how many days before the service of being included in of broadcasting and TV operations policing parameter comes into effect, the user can be accepted because of not receiving that subtracting mandate " freely " watches parameters such as time.
The Conditional Access authorization message generation unit of Subscriber Management System in Conditional Access authorization message pretreatment module sends user's service parameter, and Conditional Access authorization message generation unit goes to produce authorization message according to the strategy of user's service parameter that receives and delegated strategy library unit generation authorization message.
Send to Service Database then, Service Database sends to set-top box by conditional access system with authorization message.
The user handles subscribed services, if service should come into force, orders the same day exactly such as the date of service that the user orders, and then needs to produce first authorization message of authorizing the phase at once according to the strategy that defines and also sends.And authorize the authorization message of phase for the non-service that comes into force and next, then can produce authorization message by batch processing regularly.
In systems such as province's net, customer group is often varied.The user can segment according to various features, such as, the credit grade different for the user divides according to the situation of paying dues.In addition, economize in the system such as net and to have the conditional access systems that overlap more.In multi-user group system, if having ready conditions, a cover receives the problem that the authorization message pretreating scheme can not solve the authorization message concentrations of having ready conditions, can create the traffic volumes that the reception authorization message pretreating scheme of having ready conditions reduces authorization message of overlapping more.Every cover is had ready conditions and is received the authorization message pretreating scheme and carry out the division of groups of users at different parameters.
Such as, as the groups of users criteria for classifying, can adopt following Conditional Access authorization message pretreating scheme with credit rating: the customer group that credit rating is low, use " the theoretical term of validity of authorizing " they are 1 month pretreating scheme; And the high customer group of credit rating is used " the theoretical term of validity of authorizing " pretreating scheme as half a year.Like this, the user high to credit rating only need send once and authorize just half a year.Like this, by reasonably formulating pretreating scheme, just can reduce the authorization message traffic volume effectively.
Regularly (generally once a day in) the batch processing, essential information according to user's ordering products, by the strategy that forms in the Conditional Access authorization message pretreatment module, judge whether to need to generate authorization message, and according to the situation of reality operation, generate meet current actual motion add the authorization message beginning and ending time.According to the authorization message of this strategy generation and the commencement date and deadline of mandate, can reduce the authorization message amount as much as possible, make the CA authoring system can normally send out authorization message in time.
Fig. 3 is the schematic diagram that authorization message transmitting time section is divided in the specific embodiment of the invention.As shown in Figure 3, line segment BM represents that the user orders the whole time period of certain service, and in this time period, artificial several theories that have been divided into are authorized the terms of validity, as BC, and CG, GJ.At each theoretical term of validity of authorizing, an actual grant term of validity is all arranged, as BE, DH.The authorization message of each actual grant term of validity can send before the actual grant term of validity.
1, sends out authorization message phase AB in advance and be illustrated in the authorization message that can send first actual grant term of validity in this interval.Generally in this interval, the user can not handle unsubscribe from services, and also user's service of promptly common operation systems definition is quit the subscription of and must can be handled before this time period.This time generally can be defined as 1 day or 2 days.
2, a theoretical mandate term of validity interval of authorizing term of validity BC, CG, GJ representation theory.Also be that the artificial interval the product of user's order is divided according to objective situation, generally can be defined as 1 month.
3, authorize extended period CF to be illustrated in a theoretical threshold value of authorizing the interval back of the term of validity.Generally may be defined as for 1 week.
4, first actual grant term of validity BE, be the Start Date of subscribed services Start Date, the Close Date is the random time among first " mandate extended period " CF.For convenience, the general Close Date, desirable first authorized the Close Date of extended period, i.e. F point, and this authorization message can send any time in the AB section.
5, D Start Date of next actual grant term of validity DH authorizes the term of validity to finish (also being first Start Date of authorizing the extended period) C point to any date between first actual grant term of validity Close Date E point for first is theoretical, also is any date between the CE section.
The Close Date H point of the next actual grant term of validity is that the end of second theoretical mandate term of validity authorized the extended period to finish I point, i.e. any date in the GI section in G o'clock to second.
If the zero-time of a back actual grant term of validity covers the termination time of the previous actual grant term of validity, a then back authorization message can send in the time period at DE, if and the zero-time of a back actual grant term of validity can not cover the termination time of the previous actual grant term of validity, a then back authorization message need send in the CE time period.For convenience, general E point and the desirable same point of F point.
6, then, to the last the Close Date of an actual grant term of validity is the Close Date of service order;
7, in addition, also have a kind of situation, the M time point that is exactly the product time BM section ordered as the user then sends the authorization message of an actual beginning and ending time less than the F point in the AB time period, and promptly be B Start Date, and the Close Date is the authorization message of M.
The above value of each time period and time point in the statement, series of parameters such as the customer volume of frequency, SMS or the BOSS system that need send according to the conditional access system authorization message, the quantity that the user orders, probability that burst is ordered, each empirical parameter value calculate a fixed value.The strategy that a general cover user management system can use the set of parameter value to determine.
Fig. 4 be in the specific embodiment of the invention during service unsubscription authorization message send schematic diagram.As shown in Figure 4, the user handles the business of quitting the subscription of at the N point, and the current time does not subtract mandate if operator's suspection subscriber computer top box is received in the middle of the NE section, then only need send to subtract mandate just in the NE section time.Do not subtract mandate if the current time behind the E point, does not then need to send, because first actual term of validity passed through, and the next actual grant term of validity is because the user has handled and quit the subscription of professional just can not sending out again and do not add authorization message.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with the people of this technology in the disclosed technical scope of the present invention; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
