Description
Technical Field
The invention relates to the technical field of wireless cable modem upgrading, in particular to the technical field of wireless cable modem upgrading with mutually independent wireless module and cable modem module resources.
Background
The Cable modem part strictly follows the Data Over Cable Service Interface Specifications (DOCSIS), and the wireless module follows the IEEE 802.11 standard. Since the DOCSIS standard specifies a standard software upgrade procedure, the software upgrade of the cable modem only needs to follow the DOCSIS standard upgrade procedure directly, but the wireless module does not have any software upgrade specification. If the cable modem and the wireless module share resources (such as sharing a CPU, a DDR, a flash, an operating system, and the like), software of the wireless module and software of the cable modem may be integrated and upgraded uniformly by directly using a DOCSIS standard upgrade flow, but if the cable modem and the wireless module are independent from each other, that is, each runs its own software and hardware system (such as having its own independent CPU, DDR, a flash, an operating system, and the like), software upgrade cannot be performed directly on the wireless module by using a DOCSIS standard upgrade scheme.
For a wireless module with independent resources, the current main upgrading method is as follows: the method is characterized in that an upgrade server is independently built to upgrade software of a wireless module, for example, a separate HTTP, FTP or TFTP server is built to upgrade, so that an operator is required to build another upgrade server, and operation and network management personnel are required to be familiar with various technologies, so that the cost is increased and the operation and maintenance threshold is improved undoubtedly; meanwhile, in the prior art, the upgrade software is not digitally signed, so that potential safety hazards exist.
