Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
As shown in fig. 3, the method for managing a set-top box positioning module according to an embodiment of the present invention includes the following steps:
s302, generating an LLMI code, locally storing the LLMI code and forming a production file comprising the LLMI code, wherein the LLMI code is randomly generated and directionally transmitted, so that the LLMI code can be effectively prevented from being illegally stolen; and the LLMI code uniquely identifies the location module of the set-top box, i.e. the location module can only be identified by the LLMI code;
s304, writing the LLMI code into a positioning module of the set-top box in the production process of the positioning module;
s306, writing the Boot Loader into a designated area of the positioning module, and configuring the designated area into a write-protection mode; and
s308, in the installation process of the set-top box, the LLMI code uploaded by the set-top box is received, and authorization management is carried out on the set-top box according to the LLMI code uploaded by the set-top box and the LLMI code of the production file.
Fig. 4 is a flowchart of a specific embodiment of a method for managing a set-top box positioning module according to the present invention. After the LLMI code is generated, writing the LLMI code in the production process of the positioning module and starting the OTP mode; after the production, sale and installation of the set-top box are carried out in sequence, judging whether the LLMI code (namely the message LLMI code) uploaded by the set-top box is matched with the generated LLMI code (namely the LLMI code of the production file) or not when the set-top box is installed; if the matching is successful, the set-top box is authorized to be normally installed, and if the matching is not successful, the information of matching failure is displayed.
According to the technical scheme, the positioning module of the set top box is configured to be in a write protection mode, authorization management is carried out on the positioning module through the LLMI code, the problem that the positioning-free module is produced by illegal software is solved, and effective and fine management control over the positioning module of the set top box is achieved.
The write-protect mode is a One-Time Programmable (One Time Programmable) mode, and is not rewritable or erasable after One-Time writing. As shown in fig. 5, the main chips used by the positioning module of the direct broadcast satellite all have a built-in Flash (Flash memory) and all have an OTP function, and the register of the main chip is configured to configure the designated area of the Flash into an OTP mode. Based on the above principle, in the production process of the positioning module, a manufacturer can download Boot Loader (Boot Loader) software to a specified area and configure the specified area into an OTP mode (i.e. a write protection mode), so as to protect signature software of an encryption manufacturer of an Application (APP), and ensure the legal integrity of the positioning module software.
In one embodiment, during the installation process of the set-top box, after receiving the message LLMI code uploaded by the set-top box, the method further includes: carrying out validity check on the uploaded message LLMI code; and the authorization management of the set-top box is further based on the result of the validity check.
Specifically, as shown in fig. 6, if the signature library of the encryption vendor is illegally used, the LLMI code may be distributed through the front-end system and verified at the time of opening the card. The LLMI code can be randomly generated by a front-end system, authorized and sent to a positioning module manufacturer as the unique ID of the positioning module; the positioning module manufacturer writes an LLMI code in a production line so as to ensure that the authorization can be normally received when the card is opened. Further, if a manufacturer is found to produce an illegal location-free module, the card-opening authorization of the LLMI allocated by the manufacturer can be suspended, and the manufacturer is managed in a targeted manner. The generation of a positioning-free module can be effectively restrained, and the fine management of a front-end system is realized; the set top box and the positioning module manufacturer which are free of the positioning module phenomenon can respectively carry out objective analysis on the technical level of each link to obtain an accurate conclusion, and effective management and control are carried out by combining administrative means so as to ensure that the positioning module manufacturer is effectively supervised.
In one embodiment, the LLMI code comprises: manufacturer ID bits, random bits, and check bits of the set-top box. Specifically, the LLMI code, i.e., a Location Module Identification (Location Lock Module Identification), is a code for uniquely identifying a Location Module. In the prior art, the IMEI code of the positioning module is uploaded, belongs to international telecommunication union management and is used by adopting a continuous number section distribution principle. The LLMI code is adopted to replace the original IMEI code, and the LLMI code can be uniformly and randomly distributed and managed by a central office unit; a positioning module manufacturer writes an LLMI code in a production line and uploads the LLMI code to a front-end system server according to a preset protocol when a card is opened; and further the card-opening authorization (enabling or disabling) can be controlled according to the LLMI code state.
Alternatively, as shown in fig. 7, the LLMI code is 15 decimal digits in length, stored in 7 16 bytes. Wherein, the 1 st bit and the 2 nd bit are manufacturer ID codes (i.e. manufacturer ID bit codes); bits 3 to 14 are random bits, which can be randomly generated by the front-end system, and the number of random bits can reach 1 trillion (10)12) That is, each positioning module manufacturer can produce 1 trillion positioning modules at most; the 15 th bit is a check bit and can be calculated according to an algorithm of the check bit in the IMEI code in the prior art.
In one embodiment, locally storing the LLMI code may comprise: the LLMI code source file is stored locally.
Further, before locally storing the LLMI code source file, the method may further include: acquiring an LLMI code source file; and carrying out format check, repeatability check and uniqueness check on the LLMI code source file.
Specifically, in order to meet the management requirement on the LLMI code, an LLMI code warehousing program can be developed, and a management function of unified warehousing (i.e., local storage) of the LLMI code is realized. As shown in fig. 8, in practical application, the LLMI code source file warehousing management can be performed by the LLMI code source file warehousing program and the marketing resource management system, which is a subsystem of the user management center (SMS). The LLMI code source file warehousing management is responsible for the entry and verification of the LLMI code source files, and the verification of the LLMI code source files comprises file format verification, intra-file LLMI code repeatability verification and uniqueness verification. If the file format check and the LLMI code repeatability check are not passed, stopping the whole LLMI code source file warehousing operation; and if the uniqueness check is not passed, continuously processing the next item, and after all checks are finished, sending the processing result to the marketing resource management system for storage.
In one embodiment, locally storing the LLMI code may comprise: the production file including the LLMI code is stored locally.
Further, before locally storing the production file including the LLMI code, the method may further include: checking the management condition of the production file; and when the production file meets the management condition, carrying out check bit check, manufacturer ID bit check, repeatability check, existence check and uniqueness check on the LLMI code of the production file.
Specifically, in order to meet the management requirement of the LLMI code, the existing production file warehousing program can be modified, and the verification bit, repeatability, consistency, uniqueness and existence verification functions of the LLMI code are added. As shown in fig. 9, the LLMI code warehousing management of the production files is performed by the production file warehousing program and the marketing resource management system. The production file warehousing program carries out check digit check, manufacturer ID check, repeatability check, existence check and uniqueness check on the LLMI codes which accord with the warehousing management conditions of the LLMI codes of the production files on the basis of the original warehousing format check, content compliance check and other checks of the production files. If one of the check bit check, the manufacturer ID check, the repeatability check and the existence check fails, stopping the whole production file warehousing operation; and if the uniqueness check is not passed, continuously processing the next item, and after all checks are finished, sending the processing result to the marketing resource management system for storage.
In one embodiment, the management condition for the LLMI code warehousing may be a production date, that is, the LLMI code verification is performed for a production file whose production date is after a specific time when the production file is warehoused. In other embodiments, the LLMI code warehousing management condition can also be adjusted according to the management requirement, for example, the management condition can be a set-top box model, a decoding chip model, a main software version, or a combination of a plurality of the types.
In one embodiment, the authorization management of the set-top box according to the uploaded message LLMI code and the LLMI code of the production file may include: judging whether the LLMI code of the uploaded message is matched with the LLMI code of the production file; and in case of a match, authorizing the set-top box.
Specifically, in order to meet the management requirement on the LLMI code, the existing installation and card opening program can be modified, and an installation and opening LLMI code management flow is added when the set top box is installed and opened to realize the function of comparing and checking the LLMI code. As shown in fig. 10, the installation and opening of LLMI code management process is completed by a gateway, CRM (customer management system) and marketing resource management system together, where CRM is also a subsystem of SMS. The gateway is responsible for sending the comparison result of the original message and the base station to the CRM, and the CRM adds consistency (matching) check on the LLMI codes of the set-top box according with the LLMI code installation and activation management condition on the basis of the original installation and activation comparison process.
As shown in fig. 11, according to an embodiment of the present invention, there is also provided a management system of a set-top box positioning module, including the following modules connected in sequence:
