S2-052693 proposes the architectural requirement "the mobility management over the core network should be identical or as common as possible for all radio access systems." This contribution proposes the additional key issue section to study how to achieve this requirement, and discusses and proposes the architectural approach for this key issue. This new key issue doesn't prevent the progress of the study on the architectural solution for the other mobility related key issues.

At the joint SA WG2/RAN WGs meeting in Tallinn, the following requirement was added to 23.882. "The SAE/LTE system shall provide effective means to limit mobility related signalling during inter-RAT cell-reselection in LTE_IDLE state. For example, with similar performance to that of the "Selective RA Update procedure" defined in TS 23.060." Since then, several companies have actively contributed on this topic. However, these contributions have highlighted some lack of completeness and/or ambiguity in the requirements. This document proposes some updates to the requirements to clarify/complete them and hence to permit the technical work to progress.
