The actual algorithms used are up to the vendor/operator, but no new 'hooks' are needed for this in either system.<br /><br />SimonSimon Saundershttps://www.blogger.com/profile/11559297465679708033noreply@blogger.comtag:blogger.com,1999:blog-17500930.post-58843220460447066272009-06-03T09:30:36.890+01:002009-06-03T09:30:36.890+01:00Hi Sami

If true, then it would be understandable that they'd be unaware of functions provided by Radio Resource Management, which has been implemented (in various degrees) in all cellular networks. In WCDMA RRM function is in the Radio Network Controller (RNC) and in HSPA split between NodeB (base station) and RNC - e.g. Wikipedia gives an overview in http://en.wikipedia.org/wiki/Radio_Resource_Management<br /><br />"bandwidth management based on individual users' radio channel conditions" mentioned above can be thought to be a combination of Link Adaptation and Channel dependent scheduling, also mentioned in the Wiki page above. For a cellular guy, these are part of the basis on which the radio network is built on. Further, it makes me wonder if something really could be gained if it would be done individually buy multiple applications in multiple devices simultaneously.Sami Jokinenhttps://www.blogger.com/profile/16325163594231039820noreply@blogger.com
