20、sibility), this may modify the nature of a requirement within a referenced standard used to provide the capability. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified
21、 by date of publication and/or edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply.

35、 document, the following terms and definitions apply: Bearer Control Function (BCF): five types of BCFs are defined; BCF-G, BCF-J, BCF-N, BCF-R and BCF-T: Bearer Control Joint Function (BCF-J) provides the control of the bearer switching function, the communication capability with two associated Cal
36、l Service Functions (CSF), and the signalling capability necessary to establish and release the backbone network connection. Bearer Control Gateway Function (BCF-G) provides the control of the bearer switching function, the communication capability with its associated Call Service Function (CSF), an
37、d the signalling capability necessary to establish and release of the backbone network connection. ETSI ETSI TS 102 228 V4.1.1 (2003-11) 8 Bearer Control Nodal Function (BCF-N) provides the control of the bearer switching function, the communication capability with its associated Call Service Functi
38、on (CSF), and the signalling capability necessary to establish and release of the backbone network connection to its peer (BCF-N). Bearer Control Relay Function (BCF-R) provides the control of the bearer switching function and relays the bearer control signalling requests to next BCF in order to com
39、plete the edge to edge backbone network connection. Bearer Control Transit Function (BCF-T) provides the control of the bearer switching function, the communication capability with its associated Call Service Function (CSF-T), and the signalling capability necessary to establish and release of the b
40、ackbone network connection. Bearer Inter-Working Function (BIWF): functional entity which provides bearer control and media mapping/switching functions within the scope of a Serving Node (ISN, TSN or GSN) NOTE: A BIWF contains one Bearer Control Nodal Function (BCF-N, BCF-T or BCF-G) and one or more
41、 MCF and MMSF, and is functionally equivalent to a Media Gateway (MG) that incorporates bearer control. Bearer and Media Control (BMC) interface: interface between the BCF and the MCF NOTE: The precise functionality of this interface is outside the scope of BICC. Call and Bearer Control (CBC) interf
42、ace: interface between the CSF and the BCF Call Mediation Node (CMN): functional entity that provides CSF-C functions without an associated BCF entity Call Service Function (CSF): four types of CSFs are defined; CSF-N, CSF-T, CSF-G, and CSF-C: Call Service Nodal Function (CSF-N) provides the service
43、 control nodal actions associated with the narrowband service by inter-working with narrowband and Bearer Independent Call Control (BICC) signalling, signalling to its peer (CSF-N) the characteristics of the call, and invoking the Bearer Control Nodal Functions (BCF-N) necessary to transport the nar
44、rowband bearer service across the broadband backbone network. Call Service Transit Function (CSF-T) provides the service transit actions necessary to establish and maintain a backbone network call and its associated bearer by relaying signalling between CSF-N peers and invoking the Bearer Control No
45、dal Functions (BCF-T) necessary to transport the narrowband bearer service across the broadband backbone network. Call Service Gateway Function (CSF-G) provides the service gateway actions necessary to establish and maintain a backbone network call and its associated bearer by relaying signalling be
46、tween CSF-N peers and invoking the Bearer Control Nodal Functions (BCF-N) necessary to transport the narrowband bearer service between broadband backbone networks. Call Service Coordination Function (CSF-C) provides the call coordination and mediation actions necessary to establish and maintain a ba
47、ckbone network call by relaying signalling between CSF-N peers. The CSF-C has no association with any BCF. It is only a call control function. gateway: endpoint on a network which provides for real time, two way communication between an IP based network and an Switched Circuit Network (SCN) Gateway
48、Serving Node (GSN): functional entity which provides gateway functionality between two network domains NOTE: This functional entity contains one or more call service gateway functions (CSF-G), and one or more Bearer inter-Working Functions (BIWF). GSNs interact with other GSNs, in other broadband ba
49、ckbone network domains and other ISNs and TSNs within its own broadband backbone network domain. . The network signalling flows for a GSN are equivalent as those for a TSN. Interface Serving Node (ISN): functional entity which provides the interface with non-BICC networks and terminal equipment NOTE: This functional entity contains one or more Call Service Nodal Functions (CSF-N), and one or more Bearer inter-Working Functions (BIWF) which interact with the non-BICC networks and terminal equipme
