S2-001375 from Vice Chairman: Status of S2 E-mail approval between S2#13 and S2#14
Reports of the S2 e-mail discussion
Conclusion: Alcatel sent some comments on CSCF discovery, but too late (after the deadline).
S2-001252, 1259 and 1261 were tentatively approved in Vancouver S2 drafting meeting, and were supposed to be finally approved by e-mail, but they are asked to be finally approved now. Documents are concidered finally approved by Wednesday if no objection is made. No objections were received, so S2-001252, S2-001259 and S2-001261 are approved.
S2-001482 from AT&T: Multiple I-CSCF
AT&T propose to state that the architecture shall support multiple I-CSCFs for each operator, and a DNS-based mechanism for selecting the I-CSCF shall be developed to allow requests to be forwarded to an I-CSCF based on the location or identity of the forwarding node.
Discussion: The second part is restrictive and should be corrected to “based for example on the location…”.
It is clarified that the number of I-CSCF (1 to many) is an operator’s choice.
It’s ffs if DNS has to be used as today or if some enhancements are needed. “I-CSCF shall be developed” shall be changed to “… shall be used”. “R2000” shall not appear: the text has to be future proof.
Where to put it in 23.228 shall be specified.
Conclusion: Revised to S2-001540, with these changes.
