[Sip] issues on two different session policies in the draft "draft-ietf-sip-session-policy-framework-04"

[Yuxia Zhang <isal_yxz at huawei.com>]

hi, all

 

some issues on two diffrent session policies of draft-ietf-sip-sip session policy-framework need to be queried. could you help me? thanks. as follow,

 

Producedures in the draft only describe the usage of the session-specific policy, is right? so as for the session-independent policy, how does UAC retrieve it?

it is only through SUBSCRIBE request and only simple interactive, is it ? Then UA will retrieve the session-indepdent immediately  when UA registering himself into the network as the said in the draft that the session-independent  policy always is applied before the session-specific policy, is right ? 

 

if my understanding is right, is it indicated that there is no collide for retrieve of two different policies, then it is no necessary for UAC to differentiate the two different policies, so does the policy server ?

 

thanks again.

B.R.

 

Isal
