context: for SAE access. Requirement 2) means that a user can buy an LTE-capable ME at a certain point in time without having to change his USIM. A consequence of requirement 2) is that it is not possible for the HSS to generate special SAE authentication vectors for users, based on subscription information, as even SAE subscribers may at some point use their USIM in connection with legacy MEs that do not support a special SAE key derivation. Moreover, an ME cannot explicitly signal its capability to support SAE key derivation to a legacy SGSN. Therefore it must be assumed that the HSS has no information about the UEâs capabilities to support SAE key derivation when the UE attaches to a legacy SGSN. As noted in the section on the SAE key hierarchy, it is ffs whether this is also true when the UE attaches to an MME or a Release 8-SGSN over UTRAN. Here we present an effective solution for binding authentication vectors to SAE use. This solution is based on the AMF field of an authentication
description: System Architecture Evolution (SAE) refers to a set of standards and protocols defined by 3GPP for evolving the architecture of mobile networks, particularly focusing on the core network. It aims to provide a more efficient, scalable, and flexible framework for delivering telecommunications services.
explanation: The context mentions SAE in relation to LTE-capable MEs, USIM, HSS, and authentication vectors, indicating its role as a technological standard governing the evolution of mobile network architecture.
