UTRAN recommendation and UE allowance for non-essential corrections of a feature made only in a later release
The present document identifies functional errors in a given Release of the UTRAN technical specifications which, due to their late discovery and inessential nature, have not been corrected until a later Release.
For each such error, the approved corrective changes (pertaining to later Releases) are identified and guidance is offered as to whether and how they may be incorporated into the design of an earlier Release UTRAN and / or UE.
The present document provides recommended measures which may be adopted by UTRAN when a feature which belongs to a given release is found (totally or partially).erroneous but has only been corrected in a later release due to the late discovery and the non-essential nature of the correction.
For these features, this TR also describes whether a UE is allowed to implement the correction in the release where the feature belongs i.e. before the actual release in which the CR was made, so as to enable the same UE behaviour (implementation) irrespective of the release, as a facility to UE manufacturers and without any intension to provide this information to the network (“Early UE” , which applies to essential corrections, should not apply here).
