[edit] Voice Test Plan
(Ms. Ann Munno, VeriSign)
- Ann presented the mission statement of the Voice Test Plan.

[edit] CIBER Rejects and Revenue Assurance
(Mr. Forrest Harper, Syniverse)

- Carriers are recommended to contact their clearinghouse if any unique modification is necessary.
[edit] Billing Specifications
(Ms. Robin Thomas, MACH-Cibernet, Mr. Satoshi Shirakawa, Ms. Mayuko Sawada, KDDI)
- KDDI explained the update from last IRT.
- Since it was stated that the proposed items are already covered by Cibernet and clearinghouses, MACH-cibernet, Syniverse, VeriSign and KDDI had a teleconference to check if the items proposed by KDDI were actually covered by cibernet or clearinghouses.
- KDDI explained result of the call. WG reviewed proposed changes for Ciber manual and the items for minimum requirement exchanging between carriers.
- WG Agreed to the 13 items for billing minimum requirements.
Next Step:
- KDDI is to revise the Reference document #59 and send it out to the WG.
(Day 2 Nov 29 2007)
[edit] Prepaid Roaming
(Mr. Daniel Salek, Qualcomm)
- Daniel requested the information to find out Market size of prepaid roaming. This may be useful in constructing a business case for WIN/IS-826 support among operators and RSPs.
- SK Telecom commented that they will provide pre-paid roaming for the temporary use purpose.
- Verizon committed to provide its own data to Daniel if it could be aggregated into a total market value that would not reveal individual carriers' data.
- Daniel explained the options for recharge while roaming: SMS- or Internet-based represent simple approaches for implementation, but rely on the subscriber having some form of on-line access to money. Alternatively, 3rd-party "recharge card sharing" mechanisms are more complicated, but perhaps more suited to the prepaid demographic.
- Ricardo commented that Internet banking approach is good for the long stay visitors.
- Digicel commented that we would need other options for the customers without any bank account. Agreed: cash-only options will continue to be explored.
- Daniel has been investigating the GSM way to recharge. Information is welcome from anyone with knowledge/experience in this area.
- Daniel explained the updates on Reference Document version.0.1.
- Telus commented that Prepaid domestic roaming is now available in Canada.
- Daniel commented that most of the domestic Prepaid service is WIN-based.
- If adding any flag in CIBER to implement Prepaid roaming; it is required to update document #44(Roaming Agreement).
Next Steps:
- Continue with document updates.
- Operators to provide traces of domestic IS-826 operations to Daniel Salek.
- Operators to provide estimates of prepaid international roaming market size.
[edit] Status Reports and Metrics
(Ms. Libby Mackay, Qualcomm)
- Libby presented metrics on Call Participation, Survey Response, Face to Face attendance and CRIET usage.
- MACH - Cibernet suggested tracking the number of opened projects and the number of projects closed. Sprint suggested definition of projects closed is to have the reference document approved. WG agreed.
- It was suggested that the implementation statistics be tracked but not used to measure the open or closed status of a work item. Sprint, Verizon, KDDI agreed.
[edit] SMS Roaming
(Mr. Daniel Salek, Qualcomm)
- Daniel presented the implementation status. SMS MO is implemented in only 20% of voice implementations by now.
- Serving market differentiation for billing was previously identified as the major issue preventing deployment. For some carriers this is still the case, however a number of operators have implemented a "flat rate roaming" charge and are proceeding successfully with partner implementations. No operators announced that they have implemented a fully serve-differentiated billing plan.
- Daniel requested the update on current status of carriers:
- Verizon implemented SMS MO with flat rate (for retail). Implementation was smooth.
- Speednet implemented SMS MO smoothly.
- Sprint has not done due to its business priority reason.
- SK Telecom implemented SMS MO in 20 countries. There have been no issues.
- BTC has not implemented but will use flat rate if implemented.
- LG Telecom is implementing SMS MO and MT in all their roaming contracts. That's 15 Voice and SMS (both MO and MT for each) so far.
- KDDI has not implemented due to business priority reason. If they do, they will not follow the reference document due to the difference of network specification.
[edit] Plus Code Dialing
(Mr. Daniel Salek, Qualcomm)
- Daniel commented that issues to implement *99 may be billing system change only.
- Daniel requested the update on current status of carriers.
- Sprint has implemented it but not promoting to the customers.
- There was little continued interest in the *99 solution from the team. Based on this response there seems no driver for additional effort in the VSWG to push for implementation.
[edit] MEID
(Mr. Danniel Salek, Qualcomm)
- Question: When both a 32-bit identifier (ESN/UIMID/pESN/pUIMID) and a 56-bit identifier (MEID/SF_EUIMID) are available in the MSC billing record, which one should be used in the CIBER record? Recommendation: Use the 32-bit identifier. Even though it may not be unique (i.e. a pseudo-value), it will be directly associated with the subscription. In an R-UIM scenario, the 56-bit identifier may be associated with the device shell only, and may not pass billing system validation against the MIN/IMSI.
- Verizon Wireless and Telus are using MEID both for network and CIBER.
Next Steps:
- An update is proposed for the CIBER manual to recommend use of the shorter identifier.
- Carriers are strongly recommended to view the resources available at www.cdg.org/meid, or to contact meid@cdg.org in case that they are not aware of this issue or any of the other aspects of the introduction of MEID and EUIMID.
[edit] Feedback from Seoul and 2008 Priorities
(Ms. Libby Mackay, Qualcomm)
- Libby presented Feedback at Seoul IRT and solutions for some of them.
- Some requested items do not yet have solutions and might be considered possible 2008 work items.
- Libby asked if there is any quality tool needed.
- Verizon and LG Telecom commented they would like to know the vendors of probes (presentation from them).
- CIBER toolkit can be considered. Cibernet committed to take it as an action item.
- Most of work items are covered and some of them are closed.
- Potential Work items:
- CIBER toolkit (proposed by CIBERNET)
- Automated tool for exchanging maps(proposed by SprintNextel)
- Automated loading of IRMs (proposed by SprintNextel)
- Process of updating IRM ranges(TDS)
- WIN Triggers
- Remote OTA
- TLDN testing or documentation
- Creating a launch letter was suggested but further review shows it is already in document 44.
Next Step
- Libby to send out the survey for prioritizing the potential work items.
[edit] Updates to Existing Documents
