11 Identities p. 131

11.1 General p. 131

The Identities defined in TS 23.205 for BICC based CS Core network and in TS 23.231 for SIP-I with the following additions.

11.2 Global Call Reference p. 131

The Global Call Reference (GCR) IE is derived from the ITU-T Global Call Reference parameter (defined by ITU-T Q.1902.3 [5]).

The Global Call Reference (GCR) information element is a combination of a Network ID field, a Node ID field and a Call Reference ID field. The Call Reference ID field for LCLS is defined to contain a unique call ID.

If the serving radio access is GERAN the Call Reference ID subfield created by originating MSC server contains a unique call ID and the originating BSS ID which is a unique identifier of a Base Station Subsystem (BSS) Node within an operator's network.

The complete parameter layout is specified in TS 29.205.

The GCR is exchanged on the Nc and A interfaces to globally identify the call.

12 Operational Aspects p. 131
