Method for remotely updating software for devices in a broadband network
View Patent ↗A method includes a customer premise equipment (CPE) downloading a CPE configuration file over a machine communication network. The CPE checks the configuration file for a software load name. If the software load name is found in the configuration file, the CPE downloads an operating software image specified in the software load name, and the resets and enters an initialized state ready for service. If the load name is not found, the CPE determines if the configuration file includes a vendor table having records specific to a vendor of the CPE. If the vendor table is not found, the CPE enters the initialized state ready for service. If the vendor table is found, the CPE locates a record in the vendor table corresponding to a criteria unique to a subset of CPEs of the vendor of the CPE. If the record is found, the CPE downloads an operating software image specified in the record. If the record is not found, the CPE enters the initialized state ready for service.
1. A method comprising:
a customer premise equipment (CPE) downloading a CPE configuration file over a machine communication network;
the CPE checking the configuration file for a software load name;
if the software load name is found in the configuration file, the CPE downloading an operating software image specified in the software load name, and the CPE resetting and entering an initialized state ready for service;
if the software load name is not found in the configuration file, the CPE determining if the configuration file includes a vendor table having records specific to a vendor of the CPE, the vendor table comprising Type Length Value data fields;
if the vendor table is not found in the configuration file, the CPE entering the initialized state ready for service;
if the vendor table is found in the configuration file, the CPE locating a record in the vendor table corresponding to a criteria unique to a subset of CPEs of the vendor of the CPE;
if the record in the vendor table corresponding to a criteria unique to a subset of CPEs of the vendor of the CPE is found, the CPE downloading an operating software image specified in the record; and
if the record in the vendor table corresponding to a criteria unique to a subset of CPEs of the vendor of the CPE is not found, the CPE entering the initialized state ready for service.
2. The method of claim 1 , the vendor of the CPE identified from a media access control address of the CPE.
3. The method of claim 1 , the criteria unique to a subset of CPEs of the vendor of the CPE comprising a hardware model number for the CPE.
4. The method of claim 1 , the criteria unique to a subset of CPEs of the vendor of the CPE comprising a hardware revision number for the CPE.
5. The method of claim 1 , the criteria unique to a subset of CPEs of the vendor of the CPE comprising a software revision number for the CPE.
6. The method of claim 1 , the criteria unique to a subset of CPEs of the vendor of the CPE contained in a management information block (MIB) object for the CPE.
7. The method of claim 6 , the MIB object for the CPE stored in a non-volatile memory of the CPE.
8. A device comprising:
a file retrieval module operable to download a configuration file over a machine communication network;
a boot module to place the device into an initialized and ready for service state;
a comparison module operable to check the configuration file for a software load name, and if the software load name is found in the configuration file, to operate the file retrieval module to download an operating software image specified in the software load name, and to operate the boot module to place the device into the initialized state ready for service;
a comparison module operable to
(i) check the configuration the for a software load name, and
(ii) if the software load name is not found in the configuration file, to determine if the configuration file includes a vendor table having records specific to a vendor of the device, the vendor table comprising Type Length Value data fields, and
(iii) if the vendor table is not found in the configuration file, to operate the boot module to place the device into the initialized state ready for service, and
(iv) if the vendor table is found in the configuration file, to locate a record in the vendor table corresponding to a criteria unique to a subset of devices of the vendor of the device, and
(v) if the record in the vendor table corresponding to a criteria unique to a subset of devices of the vendor of the device is found, to operate the file retrieval module to download an operating software image specified in the record, and
(vi) if the record in the vendor table corresponding to a criteria unique to a subset of devices of the vendor of the device is not found, to operate the boot module to place the device into the initialized state ready for service;
each of the comparison module, boot module, and file retrieval module stored in a non-transitory machine memory.
9. The device of claim 8 , the vendor of the device identified from a media access control address of the device.
10. The device of claim 8 , the criteria unique to a subset of devices of the vendor of the device comprising a hardware model number for the device.
11. The device of claim 8 , the criteria unique to a subset of devices of the vendor of the device comprising a hardware revision number for the device.
12. The device of claim 8 , the criteria unique to a subset of devices of the vendor of the device comprising a software revision number for the device.
13. The device of claim 8 , the criteria unique to a subset of devices of the vendor of the device contained in a management information block (MIB) object for the device.
14. The device of claim 13 , the MIB object for the device stored in a non-volatile memory of the device.
