context: Editor's Note: If there are EPS layer control plane functions that still require confidentiality or integrity protection for NSPS use cases is FFS. Assume that two NSPS UEs are in LTE coverage, communicate over the regular LTE IP access, and that they have established a secure end-to-end connection. As noted in the previous paragraph, this cannot always rely only on normal LTE security. On high level, there are two alternatives for establishing the security. Either the security protection - based on non-3GPP credentials - is constructed as an extension to the EPS protocols (e.g., NAS, RRC and PDCP), or, the security protection is applied on a higher layer. If the protection is provided on a higher layer, it can be made largely independent from the normal EPS protocols and procedures. If an NSPS UE switches between a ProSe bearer and a normal EPS bearer during a secure communication with another NSPS UE, a security solution relying on EPS layer security either have establish security
description: National Security and Public Safety (NSPS) refers to telecommunications services catering to the specific needs of national security and public safety organizations. These services often require enhanced security features, such as confidentiality and integrity protection, beyond what is typically provided by standard LTE security mechanisms.
explanation: The context explicitly states that NSPS is a type of 'telecommunications service' designed for 'national security and public safety organizations'. This categorization is further supported by the emphasis on specialized security features required by these users.
