If the subscriber is traveling to an area where the home network  operator has a group company providing services or has a preferred  operator arrangement, the potential  for both parties to earn  roaming revenues from this subscriber is high.  However,  the  Out-roamer  usually  logs  onto  various  other  competing networks.  This  translates  into huge  loss  of  revenues  to  the  home  network. Preferred  Roamer enables  the  carriers  to  have  control  over the  roaming subscribers.  It  provides  control  to  the  home network  operator  to  ensure  that the  roaming subscribers  log  onto  preferred  networks  only.  Home network  can provide  complete  control  on  Out-roamers and  thus,  ensure  higher  revenues. The operator  can  have  roaming  tie-ups  with  partners  of  choice  and  can ensure  that  their  subscribers log  onto  the  required  network  only.  A  group  of  networks  can  enhance revenues  and  can  control the  quality  of  facilities  being provided to their subscribers.

2. Single IMSI Multiple MSISDN

Multiple MSISDN roaming enables operators to offer local  numbers to roamers who  frequently  roam between  two or more  regions/countries,  leading  to optimized  roaming  call  costs  for  roamers  and sustainable  recurring  revenue streams  for the  operators.  Operators can  benefit  by catering  to the specific needs  of  the  frequent  regional roamer  segment  via  increased  loyalty,  while retaining  the roamers  to  their  networks  while  roaming.  Roamers can  easily  avail  local  numbers  without  changing handsets,  have  local  users  reach  them via a local call and can essentially portray a multinational presence

3. CAMEL Gateway

The  benefits  of  CAMEL  are  widely  known,  yet  the  lengthy  and  costly  upgrade process  may  be prohibitive for  many  operators.  This  solution  enables  the network to have CAMEL services and  CAMEL roaming without having the need to  upgrade  to  full fledged  CAMEL  infrastructure.  The  service  provides complete  CAMEL functionality  for  non-CAMEL  networks  and  networks  with previous  versions.  This external,  standalone  platform integrates  to  the operator's  network  and  implements  all  CAMEL functional  components.  Non- CAMEL  networks are  now  able  to  realize  the  potential  of  CAMEL-based services  at  lower  cost  without  lengthy  upgrades  of network  elements  or  modifications to service platforms

4. USSD Callback Server

This  product,  primarily,  enables  two-way  roaming  for  prepaid  roaming subscribers  in  Non-CAMEL networks. Also,  advantage  of  reduced  international/  national  calling  rates  in  a  network  can  be availed  by  both Prepaid and Postpaid  international  / national  roamers.  This business case has been further  extended  by  some  operators and  they  have  started  selling  their  prepaid  cards in  countries where  major  expatriates  residents,  including countries  in  Middle- east, Africa and South-east Asia.

5. Welcome and Outbound SMS

This  solution  is  a  low  cost  marketing  and  advertising  tool  that  effectively  deliver  information  to the  users of  the  service  provider's  network.  This  tool allows  service  provider  to  push  information to inbound  roamer when  inbound roamer  selects  its  network  (Welcome  Message)  or  when  its  subscriber roams to  a  foreign network  (Bon  Voyage  Message).  It  is  an  effective  media  for  service  provider  to promote  its  mobile services.  It  can  also  be  the  media  for  commercial advertisement

6. Optimal Routing

Optimal  Routing allows a call  to be routed directly from  the Originating Switch to  the  MSC  currently serving  a mobile,  which  replaces  both  the  leg  from  the Originating  Switch  to  the  home  MSC  and the  leg  from  the home  MSC  to  the Serving  MSC. It  is  most  useful  when  the  roaming  mobile  being called  is within  the  local calling  area  of  the  calling  mobile.  Currently,  such  a  situation may  require two  long  distance  calls  even  if the  two  parties  are  within  spitting distance  .  Optimal  Routing  can reduce  this  to  a  single  local  call  and thus  save valuable  resources  for  the  operator.  This  saving may  be  extended  to  the subscriber

7. Roaming Call Assistant 

Travelers  calling  from  mobile  phones  tend  to  make  common  dialing  errors when  placing  international calls  - due  to  unfamiliar  dialing  conventions  and language  barriers.  The  result  is  lost  operator revenue  and  fewer completed calls.  This  product  provides  a  flexible,  multi-modal  user  interface  to analyze, correct  and  complete misdialed  calls.  By  completing  more  calls  and  improving the  use  of network  resources,  operators  generate additional  revenues  and visitor traffic while addressing roamers' basic needs8.

9. Global CLI Access

Global  CLI  Access  guarantees  transparent  access  to  VAS  by  delivering  the international  travelers' Calling Line Identification  (CLI)  information  to  the home  network.  This  enables  roamers  to  continue using  their  familiar short codes,  eliminating  the  need  for  cumbersome  international  numbers  and lengthy authentication  sessions, exactly as if they were at  home,  for true VHE.10. Roaming Mate
While  operators  invest  heavily  in  roaming  services  and  technology,  few resources  are  dedicated  to supporting outbound  subscribers.  Roaming  Mate lets  operators  focus  on  their  important  outbound roamers  by  enhancing their  roaming experience.

VPN  is  a  widely  used  dialing  feature  within  large  organizations,  providing convenience,  better inter-employee communications  and  use  of  resources, and reduced costs. While the extension of VPN services to the mobile phone is a  considerable  advancement,  these  services  are  limited  to  employees' home countries. Employees traveling abroad must revert to long format international  numbers  to  place their  calls,  including  international  access  and country codes, which not everyone remembers.Voice  VPN service  lets  employees  keep  in  touch  with  their home offices  easily  and  transparently,  by  enabling the  use  of  familiar  VPN  extensions  when traveling.  Voice  VPN is an  attractive  service  that  appeals to  large  business accounts  and  users  alike  because  employees  can  easily contact  their  home office without long-format international dialing, and office communications are improved, more efficient and cost-effective.11. Signaling Relay System
This  enables  a  mobile  operator  to  leverage  its  own  or  its  partner's  existing roaming  relationships to extend full-fledged  roaming  services  to  its  newer regional  networks,  without  having  to  go  through an  extensive roaming relationship  setup  process.  This  enables  operators  to  quickly  provision comprehensive  roaming  services to  all  their  regional  network  properties  with minimal incremental investment.

12. Prepaid Roaming Gateway

Prepaid  inbound  roamers  with  barred  outgoing  facility  can  have  a  prepaid account  in  the  roaming network and  make  outgoing  calls that  can  be  rated real-time.  This  will  also  enable  postpaid  and CAMEL-based prepaid roamers receive  local  calls.  This  is  an  innovative  offering  for  the  mobile operator  to attract  inbound  roamers to  the  network.  The  prepaid  roamer  can  enjoy  both home call services and VPMN call services.
