Abstract

The one way paging device enables the ISP to broadcast information to thousands of subscribers in a very cost-effective fashion. The information being broadcast usually covers a wide range of topics, ranging from periodic stock updates, trafIic condi- tions, weather forecast, to headline news, movie reviews and holiday recipes. Thus enables people on the move to have up-to-date information.

THE BACKGROUND

  The one way paging device enables the ISP to broadcast information to thousands of subscribers in a very cost-effective fashion. The information being broadcast usually covers a wide range of topics, ranging from periodic stock updates, trafIic condi- tions, weather forecast, to headline news, movie reviews and holiday recipes. Thus enables people on the move to have up-to-date information.

  With the increasing of information sent over the air, the one way paging device, which is built upon limited memory resource, encounters serious prob- lems caused by device memory full condition. The device is supposed to handle incoming messages of various lengths regardless of how much memory is available. Under the condition of memory low, com- plicated auto-deletion algorithms have to be used to make room for the new messages. This procedure not only consumes tremendous amount of processor power, but also causes the user complaining about the loss of important messages.

THE SOLUTION

  The solution to this problem is to add intelli- gence in the device memory manager software to control the length of the incoming message to be stored according to the device memory gauge.

  When a message is received, the Memory Manager would break it up into linked nodes. A long

message might consist of several nodes. When the free memory is below a preset threshold, only the first nod...
