Protocol Log Examples Of Typical Calls.

We often have requests for ‘What is a good call supposed to look like?’. In

appendix A you will ﬁnd the complete Common Air Interface protocol log of a

typical call. It includes: Call Setup, Intra-cell Handover, Inter-cell Handover, Single

TCH, Hopped TCH, and Call Termination. The log shown was obtained using a PC

Protocol Logger attached to the Protocol Interface.

Appendix A details how to set up Protocol Logging.

The sample protocol log of the Common Air Interface was obtained using the

LOGGING Pass_Filter set to: ‘+Service’. The system parameters used were the

Agilent 8922M/S power on defaults except for changing TCH2 to use MA2. Only

OSI Control Stack trafﬁc is shown. Management stack trafﬁc conﬁguring

the Agilent 8922M/S is not shown. Note that a mobile may ‘piggyback’ an

acknowledgment on a following I frame rather than use the explicit RR frame. Some

service primitives used are proprietary to the Agilent 8922M/S. Layer 3 messages

are accompanied by the full L3 message in HEX format.
