34、 simple call is the means by which a temporary logical association is established (and subsequently cleared) between two or more users within a TIPHON system for the purpose of conveying information. The meta-protocol carries sufficient information to allow a bearer to be established if required. 4.

35、2 Procedures 4.2.1 Provision/withdrawal TIPHON Simple Call is available on a per-name basis to all subscribers to a TIPHON system. 4.2.2 Normal procedures 4.2.2.1 Activation/deactivation TIPHON simple call shall be permanently activated. 4.2.2.2 Invocation and operation TIPHON simple call shall be i

36、nvoked by the calling user (party A) requesting a connection of defined parameters to a second party (party B). Party A may indicate a preferred carrier of the connection at invocation. Party A may indicate its own name at invocation to allow the called party to identify the calling party. Either pa

37、rty to the TIPHON simple call or the serving network shall be able to remove the temporary logical association formed on invocation of the service. During call set-up transcoding between different codecs may be performed. 4.2.3 Exceptional procedures If the network cannot complete the connection to

38、party B then party A shall be notified. If any of the following failure conditions are detected within a domain, the association shall be removed in each domain involved and any associated resource released. The domain that detects the failure shall supply a reason for failure to each other domain.

39、Failure conditions: No route found to called party; ETSI ETSI TS 101 882-3 V4.1.1 (2003-11) 9 Requested policy not supported; Required transport resources not available; Reserved media and transport resources released due to time out; No compatible codec supported by called party; Called user busy (

40、number of simultaneous calls exceeded); Call release before call set-up completed. 4.3 Interaction with other services or service capabilities The following list of service capability interactions include only the service capabilities which are not used for the definition of the simple call service.

49、 flow of data in the media path. The functional entity model uses the following Call Functional Entities (CFE): Calling User The application at the calling users terminal which instigates the service request; CFE1OTCThe originating user service agent in the calling users terminal that instigates the service request and processes call and bearer functions (see note 3); CFE2PEThe serving network policy control function associated with the calling users service provider; CFE3ONCThe originating call and bea
