Rapporteur: Miss Fernandez, Susana
This TR discusses and describes procedures and protocols from CT3 aspects of System Architecture Evolution (SAE) towards a higher-data-rate, lower-latency, packet-optimized system that supports multiple access technologies.
These CT3 aspects include the PCC enhancements (including impacts coming from the inter-access system handover, roaming and LBO), the QoS aspects for both 3GPP and non-3GPP networks, inter-working with external networks, MBMS and any other functions in the Evolved Packet Core (EPC) network that CT3 has impact on.
This TR is used as a placeholder for CT3 SAE materials to be moved to appropriate 3GPP technical specifications when it is sufficiently stable. As such, neither all the discussions within this TR are finished nor the procedures need to be completed. This TR may also contain some empty clauses. This TR will no longer be updated on a systematic manner and therefore contained information may become outdated.
