43、ayer Service Access Point USERMSG User Message 4 Services of the application layer 4.1 Communication modes The application layer shall provide a large variety of application services to the application process. Application processes in different devices interoperate by using services of application
44、layer over communication modes. According to transport layer, the following different types of communication modes shall exist: a) point-to-multipoint, connection-less (multicast); b) point-to-domain, connection-less (broadcast); c) point-to-all-points, connection-less (system broadcast); d) point-t
45、o-point, connection-less; e) point-to-point, connection-oriented. The application layer services that are offered shall depend on the communication mode. An application layer service shall not be applied on a communication mode for which it is not specified. Some services may be used on the point-to
46、-point connection-oriented, as well as the point-to-point connection-less communication mode, although application layer services shall always be mapped to transport layer services depending on the type of the communication mode. 7 EN 50090-4-1:2004 4.2 Service primitives of the application layer Ea
47、ch specified application layer service shall be invoked by the transport layer primitives request (req), indication (ind) and confirmation (con). For a remote confirmed service, the remote device shall use the same transport layer primitives to respond to the service. The transport layer confirmatio
48、n primitive shall only be a confirmation from the transport layer instance and shall include all data from the request plus the state which indicates whether the service was sent successfully or not. The application layer shall map the transport layer confirmation primitive to a local application la
