1 Framework for describing circuit teleservices supported

22.0033GPPCircuit Teleservices supported by a Public Land Mobile Network (PLMN)TS

Teleservices supported by a PLMN are described by a number of attributes which are intended to be largely independent.

These attributes are described and defined in specification 3GPP TS 22.001 [2].

They are grouped into three categories:

– High layer attributes;

– Low layer attributes (describing the Bearer capabilities which support the Teleservice).

– information transfer attributes;

– access attributes.

– General attributes.

Figure 1 shows the relationship between the different categories of services attributes, and their scope within a Teleservice.

NOTE 1: A transit network may not exist.

NOTE 2: Communication may be established from both ends in principle.
