Abstract

Generally, a fixed wireless telephone service is used as an alternative to wire line telephone service in rural or urban settings, particularly in developing countries. One way of providing a fixed wireless telephone service is to use a conventional cellular telephone system and couple it with a wire line tele- phone system to provide wireless service to fixed terminals throughout a geographic area.

  Generally, a fixed wireless telephone service is used as an alternative to wire line telephone service in rural or urban settings, particularly in developing countries. One way of providing a fixed wireless telephone service is to use a conventional cellular telephone system and couple it with a wire line tele- phone system to provide wireless service to fixed terminals throughout a geographic area.

  While cellular telephony operators generally expect their mobile customers to bring their units to a service center for repair, this is not a reasonable expectation for fixed subscribers where the end equipment may be placed by a professional installer. Traditionally, wire line operators assume end-to-end responsibility for their lines. Since the fixed termi- nals are provided throughout a geographic area, it would be desirable to provide remote programming, testing, maintenance and software updates of these fixed wireless terminals (FWTs).

  Motorola already offers the following solutions to customers:

  l Test and Programming commands from Analog WiLLR@.

  l OMC-F - Operations and Maintenance Center for CDMA Fixed wireless terminals. This center provides software download, testing, and parameter updates over-the-air to fixed wireless terminals.

  There are several principles that must be fol- lowed in setting up maintenance calls from a main- tenance center to an FWT.

  The maintenance system offered to customers must place a "silent O&M call." That is, it is not permissible to place a telephone call to the FWT, especially in the middle of the night when routine

testing is often done, have the connected phone ring, and only afterwards discover that the call is really intended for internal maintenance of the FWT itself. Thus, maintenance must be done using protocols that differ from the standard call, are recognized by prearranged agreement as being maintenance pro- cedures, and therefore do not ring the telephone.

  A wireless local loop system may contain both mobile and fixed subscribers. With such a combina- tion, it is essential to stay within the limits of stan- dard system protocols. Adapting an existing proto- col in a non-standard manner may lead to incompat- ibilities between mobile subscribers (which are not involved in FWT maintenance) and the target FWT population. Therefore, the existing OMC-F Release
1.0 system uses standard data calls incoming to an FWT being maintained. However, it cannot distin- guish between incoming data...
