Q series - Supplement 7 (03/99) 1 3 Definitions This supplement defines the following terms: 3.1 access session: An access session is established when two business domains are bound together in a secure relationship. The early stage of the access session is the agreement

41、of terms between domains to continue interaction and authentication of the domains. Security protection may be delegated to subsequent service sessions. Domains that offer services will enforce certain policies in the access session which are derived from the commercial and technical aspects of the

42、contract. 3.2 communication capability to a session, call, or bearer connection. 3.3 attach: A signalling capability which allows the attachment of an existing party to an existing communication capability. 3.4 bearer connection: A communication capability provided by the network connectivity provid

43、er typically between two or more parties. A bearer connection may be used to support one or more communication resources. 3.5 bearer branch owner: Typically, a party who adds a bearer branch to a bearer connection is the owner of that bearer branch. There may be several bearer branch owners per netw

44、ork bearer connection. A bearer branch owner may be associated with the root, a leaf or a party not attached to the network connection. 3.6 broker: Provides location information that the business domains use to locate other entities for the purpose of establishing communications. 3.7 call: An end-to

45、-end communications call control instance between two or more call party end points or between one call party end point and its serving node. 3.8 call owner: Typically a party who initiates a call control instance is the call owner. There is only one call owner per call. 3.9 communication capability

46、: An information transfer capability between two or more party end points. Between session control end points, the communication capability is a stream connection, between resource control end points, the communication capability is a resource connection, between bearer control end points the commun

47、ication capability is a bearer connection. 3.10 computational object: A functional entity that provides a unique function by receiving, using and generating informational objects contained or to be contained in the information flows between computational objects. 3.11 consumer: Enrolls for and consu

48、mes services. A consumer may be an individual, a household with multiple end users or a small or large business with multiple end users. 3.12 detach: A signalling capability which allows the removal of a party from a communication capability. 3.13 join: A signalling capability which allows the combi

49、ning of two or more control instances or two or more communication capabilities into one entity. 3.14 federation: The concept of federation is used here to allow entities covering limited service areas to agree to interact with peer entities to enable a larger, often global, communication area. 3.15 informational object: Information exchanged between computational objects which for example describe the characteristics of bearers, party addresses, etc. add: A signalling capability which allows the addition of a new party, or a new 2 Q series -
