Abstract

As a large subscriber equipment manufacturer, Motorola is very sensitive to the costs associated with repairing or upgrading subscriber software in the field. Although much effort goes into trying to prevent field upgrades sometimes customer visible defects are found in the subscriber software that must be fixed in order to continue to provide a high quality of service. In other instances new features are available in a new software release. How these defects and enhancements can be cheaply delivered to the field is the impetus for this Over-The-Air- Programming.

OVER-THE-AIR-PROGRAMMING (OTAP)

BACKGROUND

  As a large subscriber equipment manufacturer, Motorola is very sensitive to the costs associated with repairing or upgrading subscriber software in the field. Although much effort goes into trying to prevent field upgrades sometimes customer visible defects are found in the subscriber software that must be fixed in order to continue to provide a high quality of service. In other instances new features are available in a new software release. How these defects and enhancements can be cheaply delivered to the field is the impetus for this Over-The-Air- Programming.

THE PROBLEM

  Qpically, subscriber equipment software must be updated by sending the unit to a service center. This is an expensive process because it requires that the customer return a device to a center and a repair technician perform the upgrade on the unit itself. This time consuming and expensive process could be mitigated by somehow upgrading the subscriber while it is still in the field without costly hardware additions.

  The subscriber unit user should be able to take advantage of new features and maintenance releases at their own discretion in the same way enhance- ments are available for computer software applications. In the desktop computer industry a popular technique for updating software is through the down-loading of executable programs that patch an application in order to bring it up to the latest revision.

SOLUTION

Subscriber units that already have the ability to

transmit data in the form of either Circuit Data or Pack...
