Minutes of the S2 meeting #14 4th to 8th of September 2000 Bristol, uk

4.1.2Conclusions of the drafting group on Registration

S2-001547 from Drafting group: Output of the drafting on registration

The documents considered by the drafting are: 1442, 1452, 1453, 1460, 1462, 1464, 1465, 1541, 1508

Discussion: 2 decisions points were identified: D1 (services to be handled in the home or visited network) and D2 (which actual CSCF to chose in the appropriate network).

The criteria at D1 and D2 were studied.

D1 is an HSS function, D2 is an I-CSCF function.

Conclusion: Noted. The result is proposed to be incorporated in 23.228 as shown in S2-001616.
S2-001616 from AT&T: Text for 23.228 from drafting session on S-CSCF Selection

Material to be put in 23.228 according to the results of the drafting group in S2-001547.

Discussion: Still some concerns from KPN on the hiding of the infrastructure to external networks are made. Siemens answered that there is some ambiguities in the number of S CSCF actually deployed as one S CSCF might have different addresses.

Vodafone mentioned that hiding is necessary not only for not giving sensitive information to competitors, but also for reconfiguration concerns: it should be able to reconfigure one’s network without having to tell it to all the other network operators.

“Number of S-CSCFs” should be changed to “Exact number of S-CSCFs”.

For Nokia, the requirement is not clear: the meaning of “hiding” needs to be clarified: number of S CSCFs, IP addresses (giving e.g. only logical names), etc. An editor note shall be added to state that the requirement needs to be clarified. The clarification itself should be handled by e-mail.

“This information is stored in the HSS” in points 2 and 3 should be changed to “This information is provided by the HSS”.

“1 The Service Capabilities of the visited network for roamers.” Should be changed to “… network cap…”

“It is a requirement that it shall be possible…” has to be changed by “A network operator can…”

Conclusion: Editorially revised to S2-001635.
