Splitting 3G Voice and Data Channels
Published on:
DoCoMo has announced that it plans to separately manage call and data packet transmission congestion over its 3G network to prevent voice traffic congestion control from affecting packet communication traffic and vice versa. Currently, excessive congestion in either voice or data transmissions can force DoCoMo to limit network usage for both voice and data in order to prevent network breakdown.
One result of the move is the increased ability to successfully transmit text messages via i-mode mail, or to DoCoMo's i-mode Disaster Message Board service, even if voice traffic should rise sharply during a major disaster. The i-mode Disaster Message Board service, launched on January 17, 2004, enables i-mode subscribers to post text messages on a special i-mode site.
The new system will initially apply only to selected handsets - D902iS, F902iS, N902iS, P902iS, SH902iS, DOLCE SL, SH702iS, D702iF, N702iS, P702iD, and N902iX HIGH-SPEED.
A similar control system for the 2G mova network was implemented in April 2004."
