This work covers Stage 3 for SAE impact on existing capabilities (new TS 29.274, TS 29.275) and Stage 3 for SAE / LTE identities (changes to TS 23.003).

WID CP-080279 includes selection and specification of protocols and procedures to be used within EPC, between EPC and current GPRS core network, between EPC and HSS/AAA, and between 3GPP and non-3GPP access, and describes impacts and required enhancements for related network protocols, including GTP and IETF protocols based on Stage 2 architecture. The CT4 can be divided into the five categories:

  • MME related interfaces based on the Diameter protocol;

  • New and enhanced 3GPP AAA interfaces;

  • GTP enhancements;

  • PMIP based Mobility and Tunnelling protocols;

  • Optimized handover procedures and protocol between E-UTRAN access and non-3GPP accesses;

CT1 specified protocols for mobility management, session management, and control of NAS security.

It covers work on protocols and procedures used in the EPS or used between the UE and the EPC network via non-3GPP access networks. Furthermore, existing 3GPP specifications were enhanced to support inter-system mobility between 3GPP legacy radio access networks and E‑UTRAN. CT1 work can be split into four groups:

1) High level functions and procedures common for all accesses:

- Network selection procedures (stage 2 and 3)

- Impact on services, network functions and capabilities (e.g. impact of EPS on IMS, etc.)

2) Support of E-UTRA

- UE non-access stratum mobility procedures in idle and active mode

- Session management, bearer control and QoS aspects

- Security aspects for E-UTRA

3) Support of interoperation between EPS and legacy cellular PS accesses

- Inter-system mobility between E-UTRAN and GERAN/UTRAN

- Inter-system mobility between E-UTRAN and cdma2000

4) Support of non-3GPP accesses

- Access to the EPC via non-3GPP access networks

- Mobility management based on mobile IP

- Inter-system mobility between E-UTRAN and non-3GPP accesses

- Security aspects for non-3GPP Access
