Hi,

 

When I use the wireshark to dissect the MC interface trace, it regard each IP packet as one message. However, there are several upper layer messages enbedded in the same one IP packet.

 

Therefore, when I use the following Tshark command to dissect that, it can only generate 1 gsm message:

tshark -r MC_SAMPLE_LOGS -R "gsm_a.dtap_msg_mm_type > 0 or gsm_a.dtap_msg_cc_type > 0 or gsm_a.bssmap_msgtype > 0 or sccp.message_type > 0" -T fields -E header=y -e frame -e frame.time_epoch -e ip.src -e ip.dst -e sccp.slr -e sccp.dlr -e sccp.message_type -e gsm_a.dtap_msg_mm_type -e gsm_a.dtap_msg_cc_type -e gsm_a.bssmap_msgtype -e gsm_a.imsi > result_MO.txt

 

As below:

frame	frame.time_epoch	ip.src	ip.dst	sccp.slr	sccp.dlr	sccp.message_type	gsm_a.dtap_msg_mm_type	gsm_a.dtap_msg_cc_type	gsm_a.bssmap_msgtype	gsm_a.imsi
Frame 1: 1170 bytes on wire (9360 bits), 1170 bytes captured (9360 bits)	1271940351	10.37.11.26	10.37.19.18	0xa80003	0x0a16ec	0x05	0x08		0x55	4.60002E+14

 

The protocol hierarchy is show as below:

 

 

The original dump packet is attached as below:

Could anybody help me to repair that?

 

Thanks!

 

 

Best Regards!
