ShortCodes

Business Challenge
• Subscribers enjoy short code-based
access to a whole host of services,
including voice mail, emergency, weather,
news, etc. in their home networks.
• However, when they roam, they lose
access to these services and are unable to
retrieve critical information
 Loss of premium revenue for an
operator
 Dissatisfaction for the subscriber

Roamware Short Codes Solution
• Enables inbound and outbound roamers to access
home and local value-added services by using
familiar short codes.

Value Proposition
• Higher call completion leads to higher
revenues
• Application specific short codes like
brand name dialing leads to increased
revenues
• Enhanced subscriber satisfaction leads
to increased loyalty

Service Features
• Enables short codes services for roamers as well as local
subscribers
• 5 major categories of short codes seamlessly supported
 Emergency
 Voicemail
 Customer care
 Miscellaneous
 Brand Numbers
• Time & Location-sensitive short codes
 Escalation numbers
• Conflict resolution options
 Configurable priority for home or local short codes
 SMS messages to indicate conflict and ways to avoid it

Translation Logic
• Visited network short code
• Home network short code
• Conflict
- Emergency
- Weight

Long number generation from caller number
1. $N: Substitutes NDC Number.
2. $[n-m]: Substitutes the digits from position n to m of the
caller in the forward direction.
3. $[n*]: Substitutes the digits from position n to the end of
the caller number in the forward direction.
4. ${n-m}: Substitutes the digits from position n to m of the
caller in the backward direction
5. ${n*}: Substitutes the digits from position n to the start of
the caller number in the backward direction.
For example:
• Suppose the calling number (MSISDN) is 919811224898
and the long number is 91$N123$[6*], with 111 as the
short code. The long number at run time will be converted
to 919811123224898.
and the long number is 91$[7*]123${2-5}, with 112 as the
to 912248981232489.
and the long number is 91$[3-6]123$N33, with 113 as the
to 919811123981133.

Smart Call Assistant

Business Challenge
• Roamers encounter new dialing codes, patterns and
conventions as they roam internationally from one country to
another. Some examples include:
 International dialing codes are different for each country.
 In several countries a single operator has more than one
access code, based on the type of the network used, quality
of services offered and the price of the service.
 In some countries, the caller ID received from local fixed line
phones does not contain the international prefix. If the
roamer saves this entry as a phone book entry and tries to
use it in a foreign network, the call will not be completed.

Multiple International Dialing Codes

SCA - Business Problem
• 6-9% of all calls dialed by roamers have mistakes.
• Top reasons for mistakes
– Incorrect use of International Dialing Prefix (40-50%)
– Wrong phone book entry Using HPMN National Dialing Code to dial the HPMN
number in VPMN (17-20%).
– Typos : Using * or ** instead of +(8-15%).

Roamware Smart Call Assistance Solution
• Enables local and international call dialing easy for
roamers by automatically correcting dialing mistakes
introduced due to new and unfamiliar dialing codes
and patterns in the visited network.

Value Proposition
• Roamers
 Ease of making roamer calls without dealing with
complex local dialing patterns
 Convenience of directly using phonebook
 Superior user experience
• Operators
 Increased call completion of high margin roaming calls
 Increased network traffic and usage – increased ARPU
 Enhanced roamer satisfaction leading to increased
stickiness and roamer loyalty
 Competitive differentiator

Smart call assistant
• Two approaches of call correction
– Reactive approach
– Proactive approach
• Two types of numbering plans
- Closed dialing plan
- Closed numbering plan

Smart call assistant - Features
• Multiple Response Generation
– Connect / Continue Call
– Release call
– Update each call in database
– Send SMS and release call
• Whitelist test for new networks
• Configurable preference to home or visited number
• Add/modify/delete wrong patterns
• Enable/disable call correction sequence.
• Conflict resolution with roamer input

• Translation Logic
 Pattern Check
 Wrong International Dialing Prefix (IDP) Correction - This rule is
evaluated when dialed number starts with any of the HIDP. This is the
first check that is done for home number correction. HIDP is removed
from the number. It assumes that the number is dialed with any CC that
could be home CC, local CC or third country CC. If none of the CC is
found in the number, Home CC is added before the number. Number is
validated as per that country’s numbering plan. Third country numbers
can be corrected only by this rule. HNDP check after HCC rule is also
evaluated within this rule.
 Country Code Missing Correction - This rule is evaluated when dialed
number starts with HNDD. HNDD is removed from the number. If it does
not start with HCC, HCC is appended before the number and the
number is validated as per home numbering plan. Wrong home number
plan rule is also evaluated within this rule.

 Home Local Number Correction - This rule is evaluated when dialed
number neither starts with HIDP nor HNDD. It may or may not start
with HCC. HCC is appended if not present already. Wrong number
plan rule and HNDP after HCC check rules are also evaluated with
in this rule.
 Home National Dialing Prefix (NDP) check after home Country Code
(CC) - This rule is evaluated when number starts with CC and HNDP
is available after CC. HNDP is removed and number is validated
with home numbering plan.
 Wrong Home Number Plan Correction - This rule is evaluated when
dialed number does not match with home numbering plan, reason
being subscriber number length does not match. This happens when
some prefix is added before/after area code and the number is
dialed without that prefix. If prefix is added before area code and
validation gives error like area code not found, then prefix is added
in the number after area code and again validated with home
numbering plan.
 Toll Free Number Correction - This rule is evaluated when dialed
number matches the toll free number stored in database.

 Visited Number Correction - This is the first rule that is evaluated to
correct visited number. It checks VIDP, VNDP if available, adds
VCC, if not available and then validates number with visited
numbering plan.
 Visited National Dialing Prefix (NDP) Check after Visited Country
Code (CC) - If VNDP is found after VCC in the number, this rule is
evaluated. VNDP is removed from the number and validated with
visited CC.
 Wrong Visited Number Plan Correction - If number does not match
with numbering plan of the visited network and subscriber number
prefix is set for local network then this rule is evaluated to correct the
number.
