2 Overview of Remote Upgrade of the BSC&BTS Software Remote upgrade of BSC software is a process in which the BSC software is remotely upgraded through the M2000. Multiple BSCs can be upgraded in batches. Remote upgrade of BTS software is a process in which the BTS software is remotely upgraded through the M2000. Multiple BTSs can be upgraded at a time.

Remote software upgrade can be implemented through an automatic upgrade procedure on the GUI. This facilitates the upgrade and improves the reliability of upgrade. Remote software upgrade not only avoids inconvenient local maintenance, for example, in a remote area, but also shortens the time of service disruption due to system upgrade by upgrading multiple network elements (NEs) at a time. Remote software upgrade can be performed automatically and multiple NEs can be upgraded at a time. Thus, the working efficiency of maintenance personnel is improved, and the upgrade cost is reduced.
