How to decode traces from Shark Android app

Hi all,

I am getting traces with Shark app in a Android device. I start the capture with the default parameters (-vv -s 0) that means all the interfaces. I generate traffic such SIP,MSRP and sending some SMS and MMS... When I open the pcap file I only see traces under TCP protocol, how can I decode/decrypt the packets in SIP, MSRP, SMPP or other protocols? How can I identify wich TCP packets belongs to each protocol? Here you have the link to the pcap file: http://www.filedropper.com/sharkdump1441290581

Thank you very much in advance, Regards.
