Abstract

iDEN customers and the customers of other wireless products which are marketed towards the corporate end user often have problems keeping their phone, radio id, and talkgroup lists up to date. As radios change hands or talkgrounds are re-defined, each radio needs to be individually updated with the new call lists. This process often requires the services of a field technician trained in the use of radio service software. The larger (and thus more important) the customer, the more incon- venient this becomes.

PROBLEM DESCRIPTION

  iDEN customers and the customers of other wireless products which are marketed towards the corporate end user often have problems keeping their phone, radio id, and talkgroup lists up to date. As radios change hands or talkgrounds are re-defined, each radio needs to be individually updated with the new call lists. This process often requires the services of a field technician trained in the use of radio service software. The larger (and thus more important) the customer, the more incon- venient this becomes.

  Individual subscriber units are limited in the amount of non-volatile memory that can be allocated to storing call lists. The customers desire to store several call list entries prohibits phone manufacturers from reducing production costs by limiting the use of such memory

SOLUTION

  The solution is to store call list information on a centralized data server. The subscriber may inter- actively browse through the call list database in a manner similar to the call lists that are currently stored within the EEPROM-based codeplug. The subscriber unit communicates with the data server using wireless-IP protocols, allowing the data server to exist anywhere on the Internet, or any other IP-based network.

  The trade-off to accessing call lists over an IP network is that the speed of data retrieval is depen- dent upon network availability. Sometimes, in the

case of Radio ID lists or Talkg...
