Abstract

Speed based advanced random registration as discussed in the paper means that when the UE’s speed crosses a “speed threshold” (which may be a fixed threshold for all of the UEs or a threshold which is randomly chosen by each UE), the UE will attempt to perform a registration after a random delay time (within a certain maximum limit of course , e.g. 30 seconds). It will attempt to perform this registration even though there is no change in the registration area. This may enable NW to give a list of registration areas in advance where UE may be heading to. Note: Speed and direction of the UE can be determined in anyways e.g. using GPS or any other sophisticated device, or methods mentioned in 3GPP (For example the UE could decide to perform the speed based registration if it becomes “fast moving” according to the 3GPP definition of “fast moving, i.e. at least Ncr reselections in Tcrmax seconds. And it could send the last few cells that it has been on in order so that the network could determine its general direction of motion– rather than sending its direction of motion. With this solution, the UE would not necessarily need to have GPS capabilities in order to implement the speed based registration.), or any other method.
