Descriptions
Service users are engaged with each other via a service-provider during a certain period of time. This common engagement is well known as association, or interaction. In ETSI, the term dialogue is used for this engagement.
Two service users engaged in a dialogue, interact with a service-provider for the transfer of their messages. The point at which an interaction takes place is called service access point (SAP) located at the boundary of the service-provider, and the exchange of messages at the SAPs is accomplished by the performance of service primitives (SPs).
The SPs of the common MAP service elements contain a parameter, called Application Context Name. The value of this parameter refers to an user-specific MAP service, e.g., handover control. It is used to indicate the purpose of a dialogue. Besides it could partly be used as an identifier for a certain dialogue, by which corresponding independent message flows (of parallel dialogues) can be distinguished. A version negotiation mechanism based on the use of an application-context-name is used to negotiate the protocol version used between two entities for supporting a MAP-user signalling procedure.
The ACN facility enables the version negotiation for the following messages, which makes the UltraWAVE system more compatible with the other networks by means of flexible message version adjustment.
