No Perception Upgrade #

No Perception Upgrade for handsets is a new upgrade mode that separates the process of firmware transmission and firmware upgrading. Firmware transmission will not affect the normal use of the handset. You can upgrade the handset during working hours, greatly reducing the handset unavailability time. The upgrade of the handset will be completed within 2 minutes.

No Perception Upgrade Working Process

  1. Base station download firmware: The base station supports downloading the firmware of multiple handsets at the same time. The firmware can be imported through the web user interface, or auto provisioning triggers the base station to download the firmware.
  2. Base station transfer firmware: The base station supports simultaneous transmission of multiple types of handset firmware , the transmission process will not affect the call under the base station, and the handset can still receive calls and access LA normally. But once the handset has a call or accesses LA during the transmission, the transfer is interrupted until the handset returns to the idle interface and resumes the transfer after 1 minute. Normally (without any interruption of transmission) base station transmits a single firmware for about wide-band 60mins, narrow-band 90mins. In the case of simultaneous transmission, multiple handsets
    or multiple firmware upgraded together will take 10 minutes longer.
  3. Handset installs the firmware: The handset is installed and upgraded locally and does not need to interact with the base station during installation. The handset will prompt whether to upgrade, select Yes, and the handset will install the transferred rom package. It will take 1~2 minutes, the handset will be unavailable in process, but other handsets are not affected, and the base station is working properly.

The following table compares the handset affection during the firmware transmission and upgrade process of the three models: Normal UpgradeGrayscale Upgrade and No Perception Upgrade.

NOTE:

The firmware transmission and upgrading process are performed simultaneously.
