[edit] Discussion
[edit] Document Structure
In general the proposed document structure was approved, with no objections or major changes proposed
[edit] Specific Section Feedback
(Section numbering follows that in v0.0c of the document - likely to change for later versions)
- 3 Introduction
- Agreement that statistics would be useful. High penetration of prepaid subscribers in emerging markets. CDG may have some information as reported to it by operators.
- 6 International Implementation of IS-826
- (The subsections are in no particular order of preference right now.)
- A number of the items cross over between technical and commercial. As much as possible, the document will attempt to provide recommendations for both spheres. Operators are of course free to negotiate whatever terms they see fit between individual partners.
- 6.1 Dialplan support: Comment from the RSPs that number normalization should not be too much of a problem - it is similar to what is done today with TLDNs.
- 6.6 RSP support: In addition to general passing of IS-826 messages, modifications to parameters such as WINCAP, TRANSCAP and TRIGADDRLIST may also be necessary, as well as barring subscribers in non-prepaid markets.
- 6.7 Serving network trigger support: The options to deliver an IS-826-like experience without IS-826 support in the serving network may be limited. Possible options include triggering terminating calls from the home network only, and trunking originating calls back to the home network in order to charge for them. This to some extent defeats the purpose of IS-826.
- 6.9 Failure scenarios: i.e. including an indication in the CIBER record that the SCP did/did not bill the call to allow "catch-up billing" if necessary by the home operator.
- 6.15 Subscriber provisioning: As well as allowing prepaid subscribers to roam (which they probably can't do today), will most likely need to ensure that they can only roam in a subset of markets available to postpaid subscribers (i.e. those with whom a prepaid roaming agreement is in place). Given the "single MSCID" usually seen by the home operator from the RSP, this task may fall to the RSP (see 6.6).
- An additional suggestion was to look at customer care access - does the subscriber reach home or serving network customer care. The issues here may not be significantly different to those for postpaid subscribers.
- 7 Non-network issues
- The inter-operator relationship for billing is essentially unchanged for prepaid - CIBER records will still be produced and exchanged after the call as today. Therefore there may not need to be significant changes to the existing roaming agreements - simply defining prepaid as another service that will be offered should suffice.
[edit] Action Items
- Daniel to follow up with CDG to see if any prepaid statistics are available.
- All: continue to provide feedback and suggestions for document content and issue resolution, either via email or the wiki. Good sources of prepaid subscriber statistics are especially welcome.
- Operators: Supply ANSI-41/IS-826 traces of existing in-network prepaid call scenarios. Daniel is happy to "anonymize" these is required.
- Operators: Provide information on your own IS-826 integration experiences. Many of the problems you have already encountered and resolved are likely to be found again in the roaming case, except that this time neither network may be as ready to make changes so as to avoid impacting their own in-network services.
