6.3 Rules of association for the attribute values of connection elements and connection types

3GPP43.010GSM Public Land Mobile Network (PLMN) connection typesRelease 16TS

This subclause describes the relationship between the attribute values of connection elements and connection types. For each attribute the various possible values recommended are listed. The definitions of the attributes and attribute values are contained in the annex A. In addition to the (possible) attribute values applicable to the connection elements, an association law is given (where appropriate) for each attribute to show how the value of the attribute for the overall connection type is obtained from the values of the attribute applicable to the connection elements.

6.3.1 Information transfer mode

Attribute values for connection elements:

Circuit.

Attribute values for overall connection type:

Circuit.

Association Law:

Circuit.

6.3.2 Information transfer rate (kbit/s)

Attribute values for connection elements:

3.6 or 6.0 or 12.0 or 13.0 or 14.5 or 29.0 or 32.0 or 43.5 or 64.0

or n  6.0 ( 1  n  4 ) or n  12.0 ( 1  n  6 ) or n x 14.5 ( 1  n  5 ) or 2 x 29.0 or 2 x 32.0

Attribute values for overall connection type:

3.6 or 6.0 or 12.0 or 13.0 or 14.5 29.0 or 32.0 or 43.5 or 64.0;

or n  6.0 ( 1  n  4 ) or n  12.0 ( 1  n  6 ) or n x 14.5 ( 1  n  5 ) or 2 x 29.0 or 2 x 32.0..

Association Law:

The value for the overall connection type will be equal to the lowest value of any of its connection elements.

6.3.3 Information transfer susceptance

Attribute values for connection elements:

Speech processing functions (e.g. PLMN Speech Coding/A Law conversion, Discontinuous Transmission) and/or Echo suppression functions and/or Multiple satellite hops or null.

Attribute values for overall connection types:

Unrestricted Digital Information or Speech.

Association Law:

For an overall connection type to have the value Unrestricted digital no connection element may contain speech processing functions or echo suppression functions. Connection elements containing speech processing devices having the flexibility to change operation between speech and unrestricted digital would on the other hand be allowed to be part of a number of different connection types.

For an overall connection type to have the value speech it must contain PLMN Speech Coding/A Law conversion equipment and echo suppression functions when appropriate.

6.3.4 Establishment of connection

Attribute values for connection elements:

Demand.

Attribute values for overall connection type:

Demand.

Association Law:

If any of the connection elements are Demand, then the overall connection type is Demand.

6.3.5 Symmetry

Attribute values for connection elements:

Bidirectional Symmetric.

Bidirectional Asymmetric (Multislot connections for data).

Attribute values for overall connection type:

Bidirectional Symmetric.

Bidirectional Asymmetric (Multislot connections for data).

Association Law:

The overall symmetry can only be generated from the connection elements by analysis of the connection element values in the context of the architecture of the connection.

6.3.6 Connection configuration Topology

Attribute values for connection elements:

Point-to-point.

Attribute values for the overall connection type:

Not applicable.

Association Law:

Not applicable.

6.3.7 Structure

Attribute values for connection elements:

Unstructured or Service Data Unit Integrity.

Attribute values for the overall connection type:

As per values for connection elements.

Association Law:

Unspecified.

6.3.8 Channels

6.3.8.1 Information channel (rate)

Attribute values for connection elements:

Radio interface connection element: Full rate TCH or Full rate TCHs or Half rate TCH.

A interface connection element: 64.0 kbit/s.

Attribute values for the overall connection type:

Not applicable.

6.3.8.2 Signalling channel (rate)

Attribute values for connection elements:

Radio interface connection element: Dm.

A interface connection element: Common channel signalling system (64.0 kbit/s).

Attribute values for the overall connection type:

Not applicable.

6.3.9 Connection control protocol

Attribute values for connection elements:

Layer 2: 3GPP TS 44.005 and 44.006.

Layer 3: 3GPP TS 24.007 and 24.008, 24.011.

Layer 2: 3GPP TS 48.006.

Layer 3: TS 24.007, 24.008 and 48.008.

Attribute values for the overall connection type:

Not applicable.

6.3.10 Information transfer coding/protocol

Attribute values for connection elements:
