摘要: Disclosed are apparatus and methodology subject matters for upgrading firmware associated with one or more metrology devices and adjunct devices. Methods are disclosed for broadcast transmission of portions of a firmware image file from an originating device over a network connecting multiple devices to be upgraded. The entire image file may be transmitted as segments to be assembled by the end devices. Broadcast segments not properly received from the originating device may be retried directly from the originating device or from neighbors correctly receiving the segment. A viral propagation methodology is disclosed as an alternative to portions of the broadcast methodology.

摘要: Generally described, the disclosed subject matter is directed to improved processes for securely accessing a meter. In accordance with one embodiment, a method for providing a mobile meter reader with an authorization that may be used to establish a secure session with a meter is implemented. In particular, the method includes issuing a request for authorization to access the meter from the mobile meter reader. If the mobile meter reader maintains sufficient rights, an authorization having an encoded digital signature is generated at a host computer system and provided to the mobile meter reader. Then the method formulates and transmits an authorization command to the meter having the encoded digital signature that was generated by the host computing system.
