|The update process for IMT-Advanced technologies defined in Recommendation ITU-R M.2012 was developed in 2012 and was based on the philosophies used for the update process for the IMT-2000 technologies in Recommendation ITU-R M.1457, while incorporating the principles of Resolution ITU-R 57 and various administrative improvements and clarifications.
The previous update procedure/process for IMT-2000 developed in 2001 has served well for more than 10 years of updates, however there are a number of advantages to moving to a common procedural approach for both IMT-Advanced and IMT-2000 updates.
It was determined that the update process developed for IMT-Advanced could be utilized with some minor modifications as the procedure for future updates to IMT-2000 replacing the current Recommendation ITU-R M.1457 update procedure as was defined in Circular Letter 8/LCCE/95. The philosophy is to keep the revised Recommendation ITU-R M.1457 update process as close as possible to the IMT-Advanced update process, in order to incorporate the improvements introduced for IMT-Advanced also for the Recommendation ITU-R M.1457 update.
The relevant External Organizations also supported a move to similar processes/procedures for both IMT-Advanced and IMT-2000.
It is noted that the change to the update process for Recommendation ITU-R M.1457 as identified in this Document IMT-2000/1, administratively eases the work within all the organizations and also within the ITU-R.
