Problems solved by technology

Since the access control server is relatively independent, it requires professional deployment and maintenance, and its application cost is high
Moreover, the upgrade method of the routing system is a non-secure mechanism, which lacks security guarantees compared to the secure upgrade mechanism of the cable modem system
[0004] Due to the independence of the two systems, that is, there is no interaction and communication between the systems, the upgrades of the two systems are also independent, and it is impossible to manage and upgrade the two systems in a unified manner.
And it is also difficult to guarantee the pairing relationship between the two system versions, which may cause the device to work abnormally
When both systems are undergoing firmware upgrades, it may also cause the system to hang, bringing huge upgrade risks

Embodiment 1

[0020] figure 1 It is a flow chart of a cable modem upgrade method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where cable modems with routing functions are upgraded uniformly. This method can be performed by cable modems with routing functions. Execute, specifically include the following steps:

[0021] Step 110, the cable modem system acquires configuration information, where the configuration information includes first configuration information of the cable modem system and second configuration information of the routing system.

[0022] Wherein, the cable modem system obtains the configuration information through the configuration file delivered by the cable modem terminal system during the online registration process, or obtains the configuration information through the upgrade server corresponding to the cable modem terminal system after the cable modem system goes online successfully. Optionally, the upgrade server ...

Embodiment 2

[0063] figure 2 It is a flowchart of a method for upgrading a cable modem provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above embodiments: after the cable modem system downloads the first upgrade firmware information and before firmware upgrade, it further includes: if the download of the first upgrade firmware information fails, then Determine whether the number of retry downloads exceeds the first preset number of times, if so, wait for the next upgrade, if not, re-download the first upgrade firmware information; after the routing system downloads the second upgrade firmware information and Before performing the firmware upgrade, it also includes: if the download of the second upgrade firmware information fails, then judging whether the number of retry downloads exceeds the second preset number of times, if so, waiting for the next upgrade, if not, re-downloading the second 2. Upgrade firmware information.

Embodiment 3

[0082] Figure 4 Shown is a schematic structural diagram of a cable modem provided by Embodiment 3 of the present invention. This embodiment is applicable to the case where cable modems are upgraded uniformly. The specific structure of the cable modem includes: a cable modem system 410 and a routing system 420 .

[0083] Wherein, the cable modem system 410 is used to obtain configuration information, wherein the configuration information includes first configuration information of the cable modem system and second configuration information of the routing system; if the first current version information and the version information in the first configuration information are detected If they are inconsistent, download the first upgrade firmware information and perform firmware upgrade;

[0084] The routing system 420 is used to obtain the second configuration information when the cable modem system is not in the upgrade state, and if the second current version information is inco...

Abstract

Embodiments of the invention disclose a cable modem upgrading method and a cable modem. The cable modem comprises a cable modem system and a routing system. The method comprises the steps that the cable modem system acquires configuration information, wherein the configuration information comprises first configuration information of the cable modem system and second configuration information of the routing system; if the cable modem system detects that first current version information is not consistent with version information in the first configuration information, the cable modem system downloads first upgrading firmware information and performs firmware upgrading; and the routing system acquires the second configuration information when the cable modem system is not in an upgrading state, if second current version information is not consistent with version information in the second configuration information, the routing system downloads second upgrading firmware information based on the cable modem system, and performs firmware upgrading. Through adoption of the cable modem upgrading method and the cable modem, upgrading is managed in a unified manner, and system upgrading riskis lowered.

Description

technical field [0001] The embodiment of the present invention relates to the field of communication and network technologies, and in particular to a method for upgrading a cable modem and the cable modem. Background technique [0002] With the rapid development of Internet technology, people's demand for wireless communication is increasing, resulting in a cable modem with wireless routing. This cable modem can reduce network equipment and wiring, and simplify the network environment. [0003] In the prior art, the cable modem has two independent systems, namely the cable modem system and the routing system, and these two systems correspond to an upgrade server. Usually, the cable modem system utilizes a TFTP (Trivial File Transfer Protocol, Trivial File Transfer Protocol) server to perform firmware upgrades. The routing system uses the TR069 network management method to upgrade the firmware, and the upgrade server is the access control server corresponding to the TR069 p...
