Description / Abstract:
The present document provides SMS over IMS procedures based upon
[MMD Part-4] and [MMD Part-10].
The present document is applicable to Application Servers (ASs)
and User Equipments (UEs) providing SMS over IMS functionality.
It is the goal of this specification to allow the core network
to know as closely as possible, the current accessibility of the UE
and to deliver SMS efficiently across the appropriate access
network while minimizing the impact on the legacy systems.
