Hi all
<br />
<br />I am developing presence network agent(PNA)..IT collects the presence information from the core network elements like Serving-call session control function(scscf)..and home subscriber server(HSS). and it will construct the publish message and send it to the Presence server(PS).
<br />
<br />here my doubt is what should be the content in the publish message for network presence? 
<br />
<br />can any one suggest how to do it ? and can anyone let me know, whether there are any RFC or Specification for constructing PUBLISH message for network elements?
<br />
<br />thank you in advance 
<br />suresh
