31、earer Services Bearer Services are described by attributes, which are 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 informa

32、tion from a user access point in a PLMN to a user access point in another 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 des

33、cribe properties of the terminating network and its access point. The 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.

NOTE 2: Communication may be established from either end. NOTE 3: The information transf

35、er and access attributes of a Bearer Service relate to a direct peer-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 followi

36、ng table lists the individual attributes in each of the four groups. The Bearer Service definitions in this specification are based on the “Minimal Set“ of attributes.

39、 define the use of each Bearer Service. See specifications 4, 5, 6, 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 a

40、nd other PLMNs. The capabilities that describe the Interworking Attributes 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 ra

41、te-adapted. The Bearer Services can be grouped into the following categories: - 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 categor

42、y is used when interworking with the ISDN or PSTN “3,1 kHz audio“ service 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,

43、user access point to the interworking function, is an unrestricted 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. T

44、heir values are as follows: Information Transfer Mode: “Circuit“; ETSI ETSI TS 122 002 V13.0.0 (2016-02)83GPP TS 22.002 version 13.0.0 Release 13Information Transfer Rate: Not applicable (note 1); Establishment of Communication: “Demand“; Symmetry: “Bi-directional Symmetric“; Communication Configura

45、tion: “Point to point“. NOTE 1: The Information Transfer Rate attribute is not applicable because it depends on the reference point assumed in the PLMN, transit or terminating network. All asynchronous NT Bearer Services may support data compression to enhance user data throughput. NT Bearer Service
