This paintings covers the prestige of advanced 3G cellular community expertise, as represented by way of 3GPP’s SAE/LTE approach, from the "inside" of standardization. It offers architectures, underlying suggestions and info of techniques on numerous degrees to advertise readers’ figuring out of the ensuing layout and requisites. comments on historical past, detours, and possible choices that weren't pursued supply extra insights for non-experts. the writer attracts on his personal notes and observations from standardization conferences, on-line discussions and corporate inner analyses, in addition to reviews and briefings from colleagues around the globe, making sure that readers obtain a balanced view and deeper understanding.

Gottfried Punz is senior researcher on the community learn department of NEC Laboratories Europe and has been lively in 3GPP standardization seeing that 2005. He has contributed to the architectural and protocol layout of the advanced 3GPP method, with specific concentrate on CS fallback, domestic cells and integration with non-3GPP accesses.

Sample text

The choice between home routed traffic and local breakout can be made per APN and per user; if more than one APN is used by a UE, different cases might exist in parallel. 1 Roaming with Home-Routed traffic Roaming with PDN connectivity in the HPLMN utilizes the architecture given in Figure 3-4. It is characterized by the PDN GW being located in the HPLMN, whereas the UE is served by eNodeB, Serving GW and MME in the VPLMN (and of course there is no possibility of co-locations of Serving GW and PDN GW then).

STa/SWa: reference points between the AAA server and an trusted and untrusted non-3GPP access, respectively, for authentication and authorization of the UE. They use DIAMETER and EAP-AKA on top of it. S2a/S2b: reference points for user plane and network based mobility signaling and are using PMIPv6; additionally, S2a allows also MIPv4 in FA mode. S6b: is used for mobility related authorization at the DSMIPv6 Home Agent and the PMIPv6 LMA. S2c: is the reference point directly between a UE and the Home Agent function (within PDN GW), which is intended for client based mobility by virtue of the DSMIPv6 protocol.
