Hello All,
Please help me to get my doubt clarrified.
When i read ETSI TS 183 043 V1.1.1,
Section B.4.1.2.1 User-initiated registration speaks about Individual
Registration on AGCF.
Can you please mention the significance of individual registration?

B.4.1.2 says,
"There may a lot of terminations to register and deregister at the same time
from the MGC side. In order to avoid the
impact of the flood registration and deregistration on the IMS core network,
the Feature Manager may use some
mechanism to control the number of registration/deregistration during a
specified period of time."

If a gateway sends a Service Change for each and every end point,
Wont it really flood the registration?
In other words, how is individual registration helpful?

Generally Restart Method for ROOT termination id is sent when gateway comes
online.
Practically When will a gateway send a Service Change for each end point?
Can this be provisioned in the Gateway?

Kindly let me know further references to understand individual registraion.
Thanks and Regards,
 Karthik Prabhu
