Embodiment

[0032] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] The present invention is based on the existing wireless module and the cable modem module resource independent wireless cable modem, such as figure 1 As shown, the wireless cable modem system in this example includes a head-end system and a wireless cable modem, and the wireless cable modem includes a cable modem module and a wireless module, and the cable modem module is connected to the head-end system and the wireless module respectively, wherein the wireless The resources of the module and the cable modem module are independent of each other, and the cable modem module and the wireless module have their own CPU, DDR, flash and operating system. The specific upgrade process in this example is as follows:

[0034] After the wireless cable modem is powered on and started normally, the cable modem module enters the standard DOCSIS o...

Abstract

The invention relates to an upgrading technology for a wireless cable modem, and solves the technical problems of high upgrade cost and complex operation and maintenance of wireless cable modem software with a cable modem independent of wireless module resources. The technical scheme is summarized as follows: the cable modem downloads update software according to configuration files distributed bytermination system and when upgrade is required, and analyzes head of the update software; if the update software is update software of the cable modem, the cable modem is upgraded; if the update software is update software of wireless modules, the cable modem sends upgrading parameters to the wireless modules from the cable modem, and then the wireless modules download corresponding update software for upgrading as per received upgrading parameters. The technology has no demand for setting up another upgrade server, so it the cost is reduced and management and maintenance are easy. Tes technology is especially applicable to the wireless cable modem with the wireless modules independent of cable modem resources.

Description

technical field [0001] The invention relates to the technical field of wireless cable modem upgrading, in particular to the technical field of wireless cable modem upgrading in which the resources of the wireless module and the cable modem module are independent of each other. Background technique [0002] A cable modem that supports wireless network access. The cable modem part strictly follows the Data Over Cable Service Interface Specifications (DOCSIS for short), and the wireless module follows the IEEE 802.11 standard. Because the DOCSIS standard stipulates a standard software upgrade process, the software upgrade of the cable modem can directly follow the DOCSIS standard upgrade process, but there is no software upgrade specification for the wireless module. If the cable modem and the wireless module share resources (such as shared CPU, DDR, flash and operating system, etc.), the software of the wireless module and the software of the cable modem can be integrated, and...
