7.2 Transport control functional entities
7.2.1 T-10: Network access configuration functional entity (NAC-FE)
• Connectivity requirement:
The NAC-FE provides connectivity to IP-based and non-IP based sensor networks through
gateways.
7.2.2 T-11: Transport authentication and authorization functional entity (TAA-FE)
• Identification, authentication and authorization:
The TAA-FE provides authentication of the USN end-users and authorization of network
access.
7.2.3 T-12: Transport user profile functional entity (TUP-FE)
• Identification, authentication and authorization:
The TAA-FE provides authentication of the USN end-users and authorization of network
access.
7.2.4 T-13: Transport location management functional entity (TLM-FE)
• Location management requirement:
The TLM-FE provides location management capability at the IP layer. If a sensor network
uses IP addresses directly or a USN gateway provides IP-based connectivity, the location
information management of sensor networks at the IP layer is supported by the TLM-FE.
7.2.5 T-17: Transport resource control functional entity (TRC-FE)
• Differentiated QoS and data prioritization requirement:
The TRC-FE provides different QoS and also supports data prioritization capabilities.
7.2.6 T-18: Mobile location management functional entity (MLM-FE)
• Mobility requirement:
The MLM-FE provides functions for the support of IP-based mobility of a sensor network
as well as a sensor node.
7.3 Service control functional entities
7.3.1 S-5: Service user profile functional entity (SUP-FE)
• Identification, authentication and authorization:
The SUP-FE is responsible for storing user profiles, subscriber-related location data and
presence status data in the service stratum. A user profile is required to be provided in
support of authentication, authorization and so on.
7.3.2 S-6: Service authentication and authorization functional entity (SAA-FE)
• Identification, authentication and authorization:
The SAA-FE provides authentication and authorization in the service stratum.
