Detailed Description
To facilitate the description of the claimed embodiments, some concepts related to the present application will be described below.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a diagram of a connection relationship between a home intelligent gateway and a server according to some embodiments. As shown in fig. 1, when the home intelligent gateway is installed in a region, the home intelligent gateway is directly connected to the server, the MAC address of the home intelligent gateway is stored in the storage region of the server, and the server sends an upgrade file to the home intelligent gateway, so that the home intelligent gateway can be upgraded according to the upgrade file. When other home intelligent gateways are installed in the same area, a CDN network is connected between the server and the home intelligent gateways, namely the server and the CDN network are in communication connection, the CDN network is in communication connection with each home intelligent gateway, and MAC addresses of all the home intelligent gateways installed in the area are stored in the CDN network. Therefore, when the home intelligent gateway sends an upgrading request to the server, the server transmits the configuration file to the CDN, the home intelligent gateway sends the upgrading request to the CDN, and the upgrading file is downloaded in the CDN. In some embodiments, the home intelligent gateway includes a router, and the upgrade control method of the home intelligent gateway may be described by taking router upgrade as an example.
When The existing home intelligent gateway is upgraded, the upgrading mode mainly comprises CDN upgrading and centralized control upgrading, in The OTA (Over The Air, depending on Over The Air) scheme of The conventional home intelligent gateway based on CDN technology, the MAC addresses of The home intelligent gateway in a packing box are continuous, the home intelligent gateways distributed to various cities are transported based on The packing box, and therefore The upgrading of a designated area can be completed by using a limited number of MAC address sections. Namely, the MAC address field of a region is segmented continuously, for example, the MAC address of a region is segmented, 40 household intelligent gateways are taken as one segment, the MAC addresses of the 40 household intelligent gateways are 1-9, 11-19, 21-29, 30-39 and the like, when the household intelligent gateways in the region are upgraded, the segmentation is upgraded, namely, the 40 household intelligent gateways are upgraded firstly, and then the next 40 household intelligent gateways are upgraded after the upgrade is finished. However, the CDN upgrade method is not accurate enough in regional locking, and in an actual use scenario, the home intelligent gateway is often installed disorderly due to some errors in management, and the MAC address cannot be used to control the address in the real space.
When the centralized control upgrading is adopted, the centralized control usually means that a terminal periodically initiates an upgrading request to establish a session with a server, the upgrading request comprises terminal information, the server extracts the terminal information and compares the terminal information with the information of a server database to judge whether the upgrading is needed or not and upgrade the version used, namely, whether the upgrading is needed or not and whether the upgrading is needed or not are judged at the server. However, the centralized control upgrading mode includes a large amount of transportation and system I/O inside the server, and an upgrading packet of the upgrading mode cannot be stored by using the CDN, so that in a million-level upgrading process, a network rate of the computing center may become a bottleneck, which causes other services of the computing center to be forced to be suspended, and in order to ensure that a service of the computing center is normal, the server has to adopt a flow control algorithm, which increases computational overhead of a server side, and reduces real-time performance of terminal upgrading.
In order to solve the problems, the distributed algorithm is applied to an access network terminal (a home intelligent gateway), the network topology structure and the centralized server are not relied on, the region identification calculation is distributed to the cloud, and the calculation power and the flow of the server are saved.
Fig. 2 is a connection relationship diagram between a home intelligent gateway and a content distribution network according to the embodiment of the present application. As shown in fig. 2, the home intelligent gateway includes an interface and a CPU, and the home intelligent gateway is in communication connection with the CDN network through the interface, for example, when the home intelligent gateway performs upgrade, the home intelligent gateway sends an upgrade request to the CDN network through the interface, and after the CDN network receives the upgrade request, the CDN network downloads the configuration file into the home intelligent gateway through the interface.
The MAC version stored in the current database of the home intelligent gateway and the version of the configuration file downloaded through the interface may be the same or different, and if the MAC version is the same, the MAC version in the current database is the latest version and does not need to be updated; if not, the MAC version in the current database is not the latest version and a new version needs to be downloaded.
To facilitate identifying the version of the configuration file, the configuration file is in the format:
the product _ ID, the hw _ version, the sw _ src _ ver and the sw _ dst _ ver represent version information, and whether the MAC version stored in the current database of the home intelligent gateway is the same as the version of the configuration file downloaded through the interface can be detected according to the version information.
In order to make the MAC version in the current database of the home intelligent gateway be the latest version, the configuration file downloaded by the home intelligent gateway through the interface comprises a URL for identifying the configuration file MAC _ CFG and a version number for identifying the configuration file MAC _ CFG, and the version number corresponds to the URL. That is, the configuration file is changed, a MAC _ config field is added to the configuration file, for example, the URL of the configuration file MAC _ CFG is recorded in the MAC _ config _ URL field, and a new configuration file MAC _ CFG can be downloaded from the CDN network according to the URL of the configuration file MAC _ CFG; the MAC _ config _ ver field is added to record the version number of the configuration file MAC _ CFG to confirm whether the version number is downloaded in the home intelligent gateway or not through the version number.
In some embodiments, the configuration file is changed, adding the mac _ config field:
{
"img":
{
"product_ID":"VS002",
"hw_version":"V1.0.0",
"sw_src_ver":"V1.0.1.120",
"sw_dst_ver":"V1.1.5.138b",
"mac_limits":
{
"mac_config_enable":"1",
"mac_config_ver":"1235",
"mac_config_url":"http://ota.hbmtservice.com/VS007/mac_config.cfg",
}
"target_URI":"http://ota.hbmtservice.com/VS007/img115138b.tar",
"target_MD5":"92332638aaa2bd84cd3a1d51f62cd716",
"cycle_time":90000
}
}
wherein, product _ ID, hw _ version, sw _ src _ ver and sw _ dst _ ver in the configuration file represent version information of the configuration file, mac _ config _ ver represents the version number of the configuration file, and mac _ config _ URL represents the download address URL of the configuration file.
After receiving the downloaded configuration file through the interface, the home intelligent gateway analyzes the configuration file, obtains the version number recorded by the configuration file, compares the version number with the current MAC version number of the home intelligent gateway (the MAC version number stored in the home intelligent gateway database), and judges whether the version number obtained by analysis is consistent with the current MAC version number of the home intelligent gateway or not so as to confirm whether the home intelligent gateway needs to be upgraded or not.
If the version number obtained by analysis is consistent with the current MAC version number of the home intelligent gateway, the current MAC version number of the home intelligent gateway is the latest version number, and the home intelligent gateway does not need to be upgraded.
If the version number obtained by analysis is not consistent with the current MAC version number of the home intelligent gateway, the version number of the home intelligent gateway in the installation area is updated by the server, the home intelligent gateway needs to be upgraded, and the MAC version number in the database of the home intelligent gateway is updated according to the version number obtained by analysis.
And when the version number obtained by analysis is not consistent with the current MAC version number of the home intelligent gateway, the home intelligent gateway downloads a new configuration file MAC _ CFG according to the URL of the configuration file MAC _ CFG identified by the MAC _ config _ URL field in the configuration file, so that the home intelligent gateway is upgraded by the new configuration file MAC _ CFG.
After the MAC version number of the home intelligent gateway is successfully matched, the address information needs to be matched, namely whether the home intelligent gateway MAC is contained in an MAC address library in the configuration file is judged. When the home intelligent gateway MAC is contained in the MAC address library of the configuration file, the home intelligent gateway is successfully matched with the address information.
In some embodiments, the CDN network may periodically send the configuration file to each installation area, and after the home intelligent gateway receives the downloaded configuration file, the MAC address included in the configuration file received by the home intelligent gateway may be a home intelligent gateway MAC address library of another installation area, that is, the MAC address of the home intelligent gateway and the MAC address library included in the received configuration file belong to different installation areas, so that the installation area needs to be confirmed according to the MAC address of the home intelligent gateway and the MAC address library included in the configuration file.
In order to identify the installation area of the home intelligent gateway, the configuration file downloaded by the home intelligent gateway through the interface further comprises a config file, the config file comprises an MAC address base of the home intelligent gateway in the area and an upgrade file downloading address corresponding to the MAC address, and the MAC address in the MAC address base is discontinuous. Namely, downloading configuration files orderly from the CDN network, adding a MAC _ config file to which MAC address libraries of all home intelligent gateways in the installation area are added, the MAC addresses in the MAC address libraries being sorted by small and large, and the MAC addresses being separated by fixed delimiters, such as 08674E00001234, 08674E0005678, 08674E0000abcd,08674e000bcde.
When the installation area of the home intelligent gateway is identified, the home intelligent gateway analyzes the downloaded configuration file to obtain a config file in the configuration file, and searches whether an MAC address matched with the MAC of the home intelligent gateway exists in an MAC address library in the config file, namely, whether the MAC address of the home intelligent gateway exists in the MAC address library in the config file, if the MAC address of the home intelligent gateway exists in the MAC address library, the home intelligent gateway and the home intelligent gateway of each MAC address in the config file are positioned in the same installation area; if the MAC address of the home intelligent gateway does not exist in the MAC address base, the home intelligent gateway and the home intelligent gateway of each MAC address in the config file are located in different installation areas, at this time, the upgrade is quitted, the configuration file needs to be downloaded from the CDN again, and the installation areas are identified again.
Since each MAC address in the configuration file is a character string, a field of each MAC character string is fixed in length, and the MAC address can be represented in a numerical manner. Each MAC character string is in a 16-system form, and each MAC character string can be converted into a numerical value through the 16-system form, namely, each MAC address in a MAC address library contained in a configuration file is converted into a MAC numerical value through the character string.
After each MAC address in the MAC address pool is converted to a MAC value, the converted MAC values are sorted by size and by size, and the values corresponding to each MAC address are separated by a fixed separator, e.g., 23653818799924, 2365384518817400, etc.
And after converting each MAC address from the character string into a shaping numerical value, searching by a dichotomy by using a comparative shaping method, if a config file contains 5 MAC addresses, converting the 5 MAC addresses from the character string into the numerical values, sequencing the converted numerical values from small to large, and searching the sequenced numerical values by adopting the dichotomy, wherein the sequence is 1,2,3,4 and 5.
For example, when the home intelligent gateway MAC is converted into a value of 2, firstly, 3 is searched for from the sorted 1,2,3,4,5 by using the dichotomy, and 2 is continuously searched for from 1,2,3 by using the dichotomy, so that the MAC address matched with the home intelligent gateway MAC exists in the MAC address library.
When the home intelligent gateway MAC is converted into a numerical value of 6, 3 is searched from the sorted 1,2,3,4 and 5 by adopting the dichotomy, 2 is searched from the 1,2 and 3 continuously by adopting the dichotomy, 1 is searched from the 1,2 continuously by adopting the dichotomy, and thus the numerical value 6 corresponding to the home intelligent gateway MAC is not searched after the sorted numerical value is searched by adopting the dichotomy, so that the MAC address library does not have the MAC address matched with the home intelligent gateway MAC.
If the MAC address matched with the home intelligent gateway MAC is not found from the MAC address library in the config file, the matching of the MAC address is failed, the home intelligent gateway MA C and the MAC address in the configuration file are in different installation areas, and the home intelligent gateway is quitted from upgrading.
If the MAC address matched with the home intelligent gateway MAC is found from the MAC address library in the config file, the matching of the MAC address is successful, the home intelligent gateway MAC and the MAC address in the configuration file are in the same installation area, and the home intelligent gateway is upgraded through the configuration file.
And when the MAC address is successfully matched, the CPU acquires an upgrading file downloading address IMG _ URL corresponding to the matched MAC address from the analyzed configuration file, acquires an upgrading file IMG _ TAR according to the downloading address IMG _ URL, and performs version upgrading on the home intelligent gateway through the upgrading file IMG _ TAR.
In some embodiments, when the home intelligent gateway downloads the upgrade file IMG _ TAR according to the download address IMG _ URL, the configuration file MAC _ CFG may be deleted from the configuration file first because the upgrade file is large and the occupied field is large, and then the upgrade file IMG _ TAR is downloaded according to the download address IMG _ URL.
When the server uploads the home intelligent gateway upgrading file to the CDN, the server calculates upgrading data of the upgrading file through an algorithm to obtain an MD5 configuration file, and then uploads the upgrading file and the MD5 configuration file to the CDN together.
In order to verify that the upgrade file IMG _ TAR downloaded by the home intelligent gateway is the same as the upgrade data uploaded by the server, after the home intelligent gateway downloads the upgrade file IMG _ TAR from the CDN network, the downloaded upgrade file IMG _ TAR and the MD5 configuration file are calculated through the same algorithm, namely the MD5 configuration file of the upgrade file IMG _ TAR is verified.
If the verification of the MD5 configuration file of the upgrade file IMG _ TAR is successful, it is indicated that the upgrade file IMG _ TAR downloaded by the home intelligent gateway is the same as the upgrade data in the upgrade file uploaded by the server, and the home intelligent gateway can upgrade the home intelligent gateway according to the downloaded upgrade file IMG _ TAR.
If the MD5 configuration file of the upgrade file IMG _ TAR is not successfully verified, the upgrade data in the upgrade file IMG _ TAR downloaded by the home intelligent gateway is different from the upgrade data in the upgrade file uploaded by the server, so that the home intelligent gateway exits the upgrade at this time, and the home intelligent gateway downloads the configuration file from the CDN network again.
The household intelligent gateway comprises an interface and a CPU (central processing unit) electrically connected with the interface, wherein the interface is used for receiving a downloaded configuration file, namely the household intelligent gateway sends an upgrading request to a CDN (content delivery network) through the interface so as to download the configuration file from the CDN, and the configuration file comprises an MAC (media access control) address library of the household intelligent gateway in an area and an upgrading file downloading address corresponding to an MAC address, so that the household intelligent gateway receives the MAC address library containing all the MAC addresses of the household intelligent gateway in an installation area so as to identify the installation area of the household intelligent gateway; the MAC addresses in the MAC address library are discontinuous, and when the home intelligent gateways of the installation area are upgraded, the MAC addresses of all the home intelligent gateways need to be matched and identified, so that the home intelligent gateways of the installation area can be upgraded at the same time; after receiving the downloaded configuration file, the home intelligent gateway searches whether an MAC address matched with the MAC of the home intelligent gateway to be upgraded exists in an MAC address library, namely, whether the MAC address of the home intelligent gateway to be upgraded belongs to the installation region is checked; if the matched MAC address exists in the MAC address library, the home intelligent gateway to be upgraded belongs to the installation region, the upgrade file is downloaded according to the download address corresponding to the matched MAC address, and after the upgrade file is successfully verified, the home intelligent gateway is upgraded according to the upgrade file. The configuration file only contains a download address of the upgrade file, and the home intelligent gateway downloads the upgrade file from the CDN according to the download address without providing an upgrade package by a server, so that the calculation power and the flow of the server can be saved.
The positioning algorithm does not depend on protocols, sensors and other auxiliary algorithms in the network topology angle, and the space where the user is located is accurately positioned. The structure is optimized, the server is miniaturized, the server side is accurately and simply calculated, the cost of components is saved, the overstaffed server overhead is simplified, the hardware cost and the maintenance cost of the server are saved, and the network flow cost of the server outlet is saved.
Based on the home intelligent gateway described in the above embodiment, the embodiment of the present application further provides a method for controlling the area upgrade of the home intelligent gateway, the method applies a distributed algorithm to the home intelligent gateway, the positioning algorithm does not depend on auxiliary algorithms such as protocols and sensors in terms of network topology, the space where the user is located is accurately positioned, the server is miniaturized, the server side is refined and simplified in calculation, and the terminal optimization is realized.

In order to identify the installation area of the home intelligent gateway, the configuration file downloaded by the home intelligent gateway through the interface further comprises a config file, the config file comprises an MAC address base of the home intelligent gateway in the area and an upgrade file downloading address corresponding to the MAC address, and the MAC address in the MAC address base is discontinuous. The method comprises the steps that configuration files are downloaded from a CDN in sequence, MAC _ config files are added in the configuration files, MAC address libraries of all home intelligent gateways in an installation area are added in the MAC _ config files, MAC addresses in the MAC address libraries are sorted by small and large, and the MAC addresses are separated by fixed separators.
