<h1>BTS Software Package Management</h1>

<p>Easy commissioning of BTS as well as fast and secure software
upgrading require remote management for BTS software packages without a need
to visit the BTS site. Back-up copies, background downloading, and storage
for several different packages are essential.</p>


<p>With the BTS Software Package Management the operator is
able to store 40 different BTS software packages in the BSC. Any of the packages
can be attached to any of the BTS sites, and they can be loaded down to the
Base Control Function (BCF) units of the BTS sites.</p>


<p>All BTS software package management functions can be done
by using MML commands at the BSC site or remotely through Q3 from the NetAct.
A new BTS software package can be transferred into the BSC on a floppy disk
or through the operation and maintenance network by means of the FTAM (File
Transfer, Access and Management) protocol.</p>


<p>BTS packages are stored on the BSC's disks. The operator
can create and delete a software package, attach a package to a BCF, detach
a package, and define an initial SW package in advance for each BTS generation.
The operator can restart a BCF with a certain software package and change
the status of the packages. There are also output commands that list information
of the packages created in the BSC, list the contents of the package, and
list the software configuration of the BCFs. Ongoing package management operations
can also be listed. Software downloading is executed on BCF restart when it
does not have a software package to activate. Downloading can also be done
as a background operation when a BTS package is being attached to the BCF.</p>


<p>The BTS is also capable of storing SW packages locally.
This further reduces service interruptions during site resets. After a SW
package has been downloaded to the BTS either via BCF reset or via online
loading, it can be saved to a non-volatile FLASH-memory of BTS O&amp;M unit.
Then, during the start-up procedure, the BSC and BTS compare the master file
identities and if they match, the SW package is loaded from FLASH instead
of transferring the package from the BSC's disk. Depending on the size of
the FLASH memory, one or two SW packages can be stored locally at site.</p>


<p>For Nokia Talk-family and Nokia PrimeSite BTSs also the
firmware can be remotely upgraded except for the transmission unit TRUA. Firmware
file packets are stored as a part of the BTS software package and are not
as such visible to the user nor require any special actions. This will greatly
ease a possible field upgrade as it is not necessary to physically visit the
site. The feature includes improvement Default BTS SW Package per BTS Generation.</p>


<p>For Nokia UltraSite BTSs, software downloading is executed
after BCF reset if the BOI does not have correct software. The BTS software
can also be background downloaded to the BOI when a BTS software package is
being deployed to the BCF.</p>


<p>Downloaded BTS software application files are stored in
the BOI non-volatile memory. The files are also copied to the BB2x. Local
BTS software backup minimises BTS boot-up time because there is no need to
download the BTS software package from the BSC after each reset.</p>
