context: HSE has) and there are no authentication vectors available in the HSE for that UE and the HSE has a direct connection to the HSS, then the HSE goes to step 4. - If the "Start EMSDP session request command" is not integrity protected or has any of the security parameters wrong (against the information the HSE has) and there are no authentication vectors available in the HSE for that UE and the HSE has an indirect connection to the HSS via a EMKS, then the HSE goes to step a. 4. Authentication-Information-Request over S6x interface â The HSE uses the S6x interface to the HSS to request one or more authentication vectors using the UE IMSI. These vectors will be specific to the BEST service. The IMSI of the UE is the IMSI passed in the accounting request (Start) for that UE when the SGi interface was setup. 5. Authentication-Information-Answer over S6x interface â The HSS uses the S6x interface to the HSE to return the requested authentication vectors. These vectors are specific to the
description: The HPLMN Security Endpoint (HSE) is a network function responsible for managing security-related tasks, such as key setup and authentication vector requests, between the UE and the HSS. It plays a crucial role in ensuring secure communication and authentication within the network.
explanation: Based on the context provided from 3GPP TS 33.863, section 6.8.2.7.2, HSE is classified as a Network Function due to its involvement in security-related procedures, such as key setup messaging, authentication vector requests, and communication with other network functions like HSS over the S6x interface.
