ETSI ETSI TS 122 002 V14.0.0 (2017-03)63GPP TS 22.002 version 14.0.0 Release 141 Framework for defining Circuit Bearer Services Bearer Services are described by attributes, which a
31、re intended to be independent. These attributes are described and defined in TS 22.001 2. They are grouped into four categories: i) Information transfer attributes, which characterize the network capabilities for transferring information from a user access point in a PLMN to a user access point in a
32、nother network. (Refer to TS 22.001 2 ). ii) Access attributes, which describe the means for accessing network functions or facilities as seen at the access point in the PLMN (see TS 22.001 2). iii) Interworking attributes, which describe properties of the terminating network and its access point. T
33、he terminating network may include another PLMN or the originating PLMN. iv) General attributes, which deal with the service in general. Figure 1 shows the relation between the groups of attributes and their fields of applicability. Information Transferand AccessAttributes (note 3)Interworking Attri

NOTE 2: Communication may be established from either end. NOTE 3: The information transfer and access attributes of a Bearer Service relate to a direct pee
35、r-to-peer communication of: - TE to TE; - TE to a network gateway (supporting, for example, PSTN interworking); or - network gateway to a TE. Figure 1: Relation between the groups of attributes and fields of applicability The following table lists the individual attributes in each of the four groups
36、. The Bearer Service definitions in this specification are based on the “Minimal Set“ of attributes.

38、e X Interworking Attributes General Attributes Supplementary Services Provided Quality of Service X Operational and Commercial Attributes that are not part of the minimal set provide further technical detail and are required to fully define the use of each Bearer Service. See specifications 4, 5, 6,
39、 7 for information about the Signalling Access Protocols, Information Access Protocols and related access attributes. Supplementary services are defined in TS 22.004 3. Intercommunication is required with services in the PSTN, ISDN and other PLMNs. The capabilities that describe the Interworking Att
40、ributes are described in specifications 8 to 9 and 15. 2 Bearer Service categories All Bearer Service categories provide information transfer between the reference points and allow the use of sub-rate information streams which are rate-adapted. The Bearer Services can be grouped into the following c
41、ategories: - Unrestricted Digital Information (UDI); Provides the transfer of unrestricted digital information. - 3,1 kHz (External to the PLMN); Used to select a “3,1 kHz audio“ interworking function at the MSC. This service category is used when interworking with the ISDN or PSTN “3,1 kHz audio“ s
42、ervice and includes the capability to select a modem at the interworking function. “External to the PLMN“ indicates that the “3,1 kHz audio“ service is only used outside of the PLMN, in the ISDN/PSTN. The connection within the PLMN, user access point to the interworking function, is an unrestricted
43、digital connection. 3 Bearer Services This clause provides a list of the existing Bearer Services and indicates the values for each attribute in the minimal set. The following attributes have the same value for all Bearer Services. Their values are as follows: Information Transfer Mode: “Circuit“; E

NOTE 1: The Information Transfer Rate attri
45、bute is not applicable because it depends on the reference point assumed in the PLMN, transit or terminating network.
