Scope

The present document defines a set of Bearer Services to be provided to PLMN subscribers by a PLMN itself and in connection with other networks. This TS should also be used as a reference for defining the corresponding required mobile network capabilities. Bearer Services not included in this TS that require modifications to the signalling specifications should not be introduced unilaterally by a mobile network operator.

Framework for defining Bearer Services

Bearer Services are described by attributes, which are intended to be independent. These attributes are described and defined in GSM 02.01 [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 another network. (Refer to GSM 02.01 [2] ). ii) Access attributes, which describe the means for accessing network functions or facilities as seen at the access point in the PLMN (see GSM 02.01 [2]). iii) Interworking attributes, which describe 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.

General Attributes (note 2)

NOTE 1: A transit network may not exist for a Bearer Service. 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 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 following 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. Table 1: List of Bearer Service attributes

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. General Packet Radio Service (GPRS) is specified in TS 22.060 [14]. See specifications [4], [5], [6], [7], [15] 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, PDN, PSPDN and other PLMNs. The capabilities that describe the Interworking Attributes are described in specifications [8] to [10] and [16].

Bearer Service categories

All Bearer Service categories provide information transfer between R/S reference points and allow the use of sub-rate information streams which are rate-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 category 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, user access point to the interworking function, is an unrestricted digital connection. PAD; Provides an asynchronous connection to a PAD. This enables PLMN subscribers to access a packet network (PSPDN/ISDN). Note: From release 99 onwards only Basic PAD access is supported. Packet; Provides a synchronous connection that enables PLMN subscribers to access a packet network (PSPDN/ISDN). See TS 29.006 [9] for service and interworking specifications. NOTE: From release 99 onwards only Basic Packet access is supported; General Packet Radio Service (GPRS). GPRS provides Internet (IP) and X.25 interworking with external networks. See TS 22.060 [14].

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: Information Transfer Rate: Establishment of Communication: Symmetry: "Circuit" (note 1); Not applicable (note 2); "Demand"; "Bi-directional Symmetric" (note 3);

Communication Configuration:

"Point to point".

NOTE 1: GPRS (BS 70) requires "packet" information transfer mode. NOTE 2: The Information Transfer Rate attribute is not applicable because it depends on the reference point assumed in the PLMN, transit or terminating network. NOTE 3: GPRS (BS 70) require a value of "Bi-directional Asymmetric". All asynchronous NT Bearer Services may support data compression to enhance user data throughput. NT Bearer Services 20 and 30 may support V.120 interworking, enabling data terminals connected to an MS to interwork with V.120 [13] terminal adapters on the ISDN as shown in the figure 2 below.

General bearer service user data characteristics

The tables below describe the characteristics of the General Bearer Services. The indicated fixed network user rates are possible, but support of General Bearer Service does not imply support of all rates.
