History of the International Roaming Team (IRT)

• 1998 the CDG initiated a technical team focused on Roaming – Original group: Hutchison Hong Kong, KDDI, Telecom New Zealand and SK Telecom

– Roughly 10 members met 2 times a year face to face

– First document created: Doc #44 CDMA International Roaming Agreement Template

• Organized into a formal structure in 2002 – Formalized and focused group charter on International Roaming with face to face

meetings

• Current organization formed in 2004 – Average 80-100 participants

– 43 published documents

– Meets face to face 2 times a year with conference calls in between

The purpose of the IRT

• Our purpose is to provide a forum and structure for the industry to improve roaming for CDMA carriers and subscribers by: – increasing CDMA roaming coverage for all services – Reducing complexity and time of deployment – Improving the reliability and richness of the subscriber experience

• CDMA is a flexible technology with implementation variances

– When roaming was added into a carrier’s product line, many found CDMA roaming to be challenging

• The only place where CDMA carriers/vendors/OEMs meet to discuss CDMA international roaming

CDMA Subscriber growth 2001 - 2015

Globally 80% of all new mobile subscribers are prepaid

Credit control for subscribers prevents bill-shock concerns

Exciting new Voice, SMS and Data bundles used to win subscribers

Operators must implement Policy control and Enforcement for inbound and outbound traffic

CDMA operators have great opportunity to win traffic if operational challenges are overcome

Some Vodafone Prepaid Experiences • Typically between 25-40% of VF roamers are prepay

• Largely varies by market: example, VF IT’s domestic base is 90%+ prepay therefore

they represent much higher proportion of roamers.

• Prepay roaming generally have lower roaming ARPU’s than post-pay and more seasonal (i.e. most travel during summer).

• About 20% of the VF consumer roaming income = prepaid

• We have evidence to suggest that around 30% of prepay customers run out of credit when they roam!

• Prepay roaming is an important source of income for Vodafone

• Several projects to further stimulate and facilitate prepaid roaming are being executed

SPRINT

IS 826 Inbound Roaming

Sprint Implementations

• North American Implementations

– Two in the US

– One in Canada

– Third US carrier is in process

Commercial Challenges

• Trigger List must contain PC-SSN and no GTA-TT. If GTA-TT, Sprint will not honor it and call processing fails.

• For the Connect Resource message, which performs redirect to a new number or announcement, the reply must contain digits that can be dialed on the PSTN.

• Review of the triggers that are planned to be used, (e.g. OAA , T Answer, T disconnect, No Answer List). Sprint has very limited announcements for mapping to WIN and cannot support all IS41D Standard Announcements

Technical Challenges

• Technical Challenges (Sprint vendor specific issues) – Qual Dir’s were stripping the WIN triggers in Sprint’s Lucent

MSC’s – Certain announcements were not supported by Sprint due to

translations conflicts. – Sprint does have to build a ‘G’ link in its Lucent MSC’s for the

IS826 SCP point code – ISCP was removing the leading 1 from Analyzed Digits causing

Sprint’s Nortel MSC’s to block calls. – Usually IS826 are deployed first on the home network in which

they use short codes to redirect callers to customer care, etc.. When implementing on Sprint we found problems with the call redirecting using their short codes and had to develop special translations to convert short codes to dialable numbers, Toll Free etc..
