This type comprises all data transmitted on the end-to-end traffic channel by users to other users. The data could be digital data, voice, or any other kind of data generated by the user.
This type comprises data relating to charges incurred by users whilst using network resources and services. Such data would normally be generated by and passed among network operators.
This type comprises data relating to charges incurred by subscribers for charges made by their users. Such data is generated by a home environment (using charging data obtained from network operators) and passed to subscribers.
This type comprises location data regarding a user (or terminal equipment). Such data is generated by a network operator and passed to the user's home environment (it may or may not be retained by the network operator).
This type comprises data relating to addresses associated with end users (and possibly terminal equipment). Such data is generated by home environments and distributed to users. It is transferred from a user to network operator to initiate a call, and then passed by the network operator to the associated user's home environment.
This type comprises data which determines the identity of an entity. The entities of interest are usually users. User identities are generated by the appropriate home environment, and are stored on the home environment's database and on the USIM. User identities may accompany user-related data such as charging, billing, and location data when it is passed between entities.
Security management data:
This type comprises data relating to security management. It includes data such as encryption keys and authentication messages, and may be generated by a third party or the involved entities themselves.
This type comprises data passed through the network to enable correct routing of calls. Such data will be generated by home environments or network operators (using location and addressing data) and passed amongst network operators.
Network resource management data:
This type comprises data relating to the physical access of a terminal to the network operator and to the physical interface between network operators. Such data is generated by network operators and passed amongst network operators and terminals.
Access control management data:
This type comprises data relating to access control to terminal equipment, network resources and service profiles. Such data may include PINs generated by users, and databases of identities generated by home environments and network operators. It is generally stored by the generating entity.
Service profile data:
This type comprises data regarding the service profiles of users. Such data is generated and passed between a user and the home environment.
Additional call control data:
This type comprises all data needed to set up, maintain, or release a call, other than identity, addressing and routing data. Such data will be generated by users or network operators and passed between users and network operators, or between network operators.
