RE: COPS for UMTS

[Salkintzis Apostolis-Y1026C <salki@motorola.com>]

My understanding aligns with Brian's statement below. The Go interface, as specified in 23.207, is used for "service-based local policy and QoS inter-working". Nothing is mentioned about provisioning.

In addition, 23.207 mentions that "Additional UMTS-specific information elements must be included in COPS messages to support the policy and QoS inter-working functions identified in Section 5.3.1. Consistent with the COPS framework, the Go interface is identified by a "client type" allocated for a UMTS COPS  client (GGSN)."

Therefore, it is implied that a new COPS client is expected to be used across Go interface.

Regards,
Apostolis

3G.PP is only specifying COPS usage for an admission control function 
for service based control. It is not specifying COPS for any other 
provisioning, (vendors can use whatever provisioning tools they wish for 
IP services).
