Abstract
The invention relates to a technology of communication between an SMS and a peripheral system, in particular to a data organization structure with which the SMS communicates with the peripheral system. The invention discloses a method by which the subscriber management system of digital TV communicates with the peripheral system, which adopts the technical proposal that: the interface of the SMS peripheral system is switched to C/S; the SMS is connected with the peripheral system; the SMS sacks the sent data; the data packet comprises a packet head and a packet body; the packet head comprises a protocol version number, an encryption version number, an encryption type, an serial number of the operator and a length of the packet body; the packet body comprises a message serial number, a message type, a data length, the content of the data packet and data abstract; the packet body is encrypted; the SMS sends the data package to the peripheral system through the interface. The invention has the advantages that: the subscriber management system of digital TV can transfer data to the peripheral system safely and accurately, enabling the smooth interaction of data between front-end systems of digital TV.
Description
Technical field
The present invention relates to the communication technology of SMS and peripheral system, particularly the data organizational structure that communicates by letter with peripheral system of SMS.
Background technology
SMS (Subscriber Management System) Subscriber Management System is to adopt digital technology, network technology, the operation management information system that user's subscribing digital television product is served.SMS is by record and processing to user's ordering information, form customer data base, with peripheral system CAS (Conditional Access System, condition receiving system), EPG (Electronic Program Guide, electronic program guides), PMS (Program Management System, program management system) etc. carries out data interaction.
In order to make the digital TV front-end system can close fit, accomplish system integration, need between SMS and peripheral system to finish exchange between the data by the interface between software and hardware of agreement, finish management jointly to the subscribing digital television product user.For reducing system resource and improve security of system, reliability, both sides should adopt the data organizational structure of agreement to carry out the data set bag.
Summary of the invention
Technical problem to be solved by this invention is to provide and realize safety, the digital TV subscriber management system of accurate interaction data and the communication means of peripheral system between a kind of digital TV subscriber management system and the peripheral system.
The technical scheme that the present invention solve the technical problem employing is that the communication means of digital TV subscriber management system and peripheral system is characterized in that, comprises the following steps:
A, the interface that digital TV subscriber management system and peripheral system be set are the C/S mode;
B, digital TV subscriber management system and peripheral system connect;
C, digital TV subscriber management system package to the data that send, and packet is made of packet header and inclusion, and packet header comprises: protocol version, encrypted version this shop, encryption classification, operator's numbering, inclusion length; Described inclusion comprises: message numbering, type of message, data length, packet content, data summarization; And inclusion encrypted;
D, digital TV subscriber management system send to peripheral system by interface with packet;
Further, the group packet mode of the packet that sends of the group packet mode of the packet that returns to the digital cable customers system by interface of described peripheral system and digital TV subscriber management system is identical.
The invention has the beneficial effects as follows, can transmit data safely, exactly between digital TV subscriber management system and the peripheral system, realized data smoothly mutual between the digital TV front-end system.
The invention will be further described below in conjunction with embodiment.
Embodiment
The interface that digital TV subscriber management system (SMS) and peripheral system are set is the C/S mode, and SMS and peripheral system be server each other, each other client; SMS and peripheral system are set up session connection, and the data to SMS system's transmission to the periphery package then, and packet is made up of packet header and inclusion, and its form is as follows respectively:
The packet header of packet:
Bits explains
Data_Packet(){
Protocal_Version 8 protocol versions
Crypt_Version 6 encrypted version this shops
Key_Type 2 encrypts classification
Operator_ID 16 operators numbering
Client_ID 16 client number
Data_Len 16 inclusion length
Data () inclusion content
}
The inclusion of packet:
Bits explains
Data()
{
Message_ID 16 message numberings
Message_Type 16 type of messages
Data_Length 16 data lengths
Data_Content () packet content
Message_Auth 128 data summarizations
}
SMS will encrypt data before the packet that the group of system's transmission is to the periphery wrapped, and promptly the inclusion of packet was encrypted, and cipher mode can adopt general cipher mode, as 3DES and DES, with the safety that guarantees data passes and reliable.SMS to inclusion encrypt finish after, SMS sends to peripheral system by interface with packet, the transferring command request, after the peripheral system fill order, by interface to SMS return data bag, the result that transferring command is carried out, the group packet mode of the packet that returns is identical with the group packet mode of the packet that digital TV subscriber management system sends.The form of the packet that SMS and peripheral system are mutual is all identical, the data content part in the inclusion of different just packet.The packet that sends when for example, SMS and CAS set up session is described below:
Unsigned?char?session[30]＝
{0x01，0x06，0x00，0x01，0x00，0x01，0x00，0x18，
0x00，0x01，0x00，0x01，0x00，0x00，0xe1，0xee，0x84，0x14，0x74，
0xbb，0x8e，0x30，0xad，0xd7，0xe8，0xb1，0xbd，0x52，0x0b，0xd7}；
The packet header of packet is " 0x01,0x06,0x00,0x01,0x00,0x01,0x00,0x18 ", and inclusion is " 0x00,0x01; 0x00,0x01,0x00,0x00,0xe1,0xee, 0x84,0x14,0x74,0xbb; 0x8e, 0x30,0xad, 0xd7,0xe8,0xb1,0xbd, 0x52,0x0b, 0xd7 ".Wherein, " 0x01 " presentation protocol version number is 1, " 0x0 " expression encrypted version this shop is 1, " 6 " expression is encrypted classification for not encrypting, " 0x00 0x01 " expression operator is numbered 1, " 0x00 0x01 " expression client is numbered 1, and " 0x00 0x18 " expression inclusion length is 24Bytes; " 0x00 0x01 " expression message numbering is 1, message numbering is for increasing the type sequence number certainly, " 0x00 0x01 " expression type of message is 1, " 0x00 0x00 " expression data length is 0, and " 0xe1 0xee 0x84 0x14 0x74 0xbb 0x8e0x30 0xad 0xd7 0xe8 0xb1 0xbd 0x52 0x0b 0xd7 " represents data summarization.
