Abstract

The lower priority outbound signaling packets (OSPs) that exist in the OSP sequencer do not need to be transmitted as frequent as the higher priority ones. This becomes critical when the control chan- nel is fully loaded with OSPs because if the lower priority OSPs are transmitted as frequent as the higher priority ones, the transmission timing requirement of the higher priority OSPs may not be fulfilled. Thus, an OSP transmission reduction mechanism is needed to reduce the transmission fre- quency of the lower priority OSPs.

OPTIMIZATION OF OUTBOUND SIGNALING PACKET TRANSMISSION

by Mak So, Jeffrey Shroda and Hemant Pate1

STATEMENT OF PROBLEM

  The lower priority outbound signaling packets (OSPs) that exist in the OSP sequencer do not need to be transmitted as frequent as the higher priority ones. This becomes critical when the control chan- nel is fully loaded with OSPs because if the lower priority OSPs are transmitted as frequent as the higher priority ones, the transmission timing requirement of the higher priority OSPs may not be fulfilled. Thus, an OSP transmission reduction mechanism is needed to reduce the transmission fre- quency of the lower priority OSPs.

PRIOR ART

  Currently, OSP messages received by the control channel are added to the OSP sequencer and sent sequentially to the DSP for transmission. If a prede- termined number of OSPs is reached, a counter in

the header of every OSP, which keeps track of the number of times an OSP should be transmitted before the OSP is removed from the sequencer, will he decremented. By doing so, the number of times a specific OSP required to be transmitted is altered. This may cause the subscriber units to miss the reception of some of the OSPs.

DESCRIPTION OF INVENTION

  By using a preset wait count in the header of each OSP to be transmitted, when an OSP is exam- ined by the sequencer for transmission, it will be bypassed if the wait count is larger than zero. The wait count will then be decremented and...
