  • one major drawback of these VOIP based solutions is that the mobiles suffer voice quality issue as the VOIP calls are not using voice circuits but they use the data circuits. Also, due to this the mobile subscriber suffers from poor data coverage issue as well as data roaming charges when making these international calls abroad.
  • the other limitation of using VOIP calls is the unavailability of data circuits in certain areas within a mobile operator's network. In such cases the subscriber cannot avail these VOIP based calling solutions.
  • Non-VOIP solutions are offered by a few operators.

  • a similar non-VOIP based solution is also being recently launched by Google, as Google Voice application.
  • Google Voice a separate client application needs to be installed and the subscriber is only provided with a local US number that is mapped to some numbers within Google's infrastructure.
  • the present invention is directed towards a method and system for mobile communication where a gateway facilitates routing of a subscriber's MO call to a called party through a local number. This routing is done by the gateway when the subscriber is present in either home country (i.e., the country of the subscriber's home network, for example) or a visited country and the called party is present in same or different country from the subscriber. In other words, the subscriber initiates either an international or national roaming call from either within his home network or any visiting network to a called party that may be in a network / country different from the subscriber.
  • the gateway further stores the local number corresponding to the subscriber either at the gateway or at the subscriber's mobile device or both. The gateway routes the subscriber's MO call by forwarding the subscriber's MO call from the local number to the called party number.

  • gateway 120 can be used in RCS ecosystem that supports geographically redundant gateways around the world. Further several such ecosystems can form a meta-ecosystem.
  • the gateway 120 routes subscriber 102's MO international call to a called party (in destination network as shown in Fig. 1) through a local number (fetched from local POP 118), thereby turning subscriber 102's international call into a local call.
  • This called party can be either in a destination network or in home network (HPMN 104) or visiting network (VPMN 106).
  • the subscriber 102's caller ID and the called international number (called party) and subscriber's country (VPMN 104) from the MO call is initiated is mapped to a fixed local number in the gateway 120 where this mapping is stored both in subscriber's mobile device and at gateway 120. So if subscriber 102 directly dials the fixed local number at the country, the call will reach the called party's number.
  • the caller ID and dialed entry are sent via data channel to gateway 120.

Default action is adding to gateway 120. Thereafter, the DNIS mapping gets associated with both old caller ID and new caller ID of the same country. This mapping is stored on both subscriber's device and gateway 120. This stored entry in gateway 120 serves as an address book backup.
  • the mapping can be dynamically established by gateway 120 as subscriber 102 makes the MO call via Smart Dialer application. Alternatively, the mapping can be built whenever subscriber 102 is having an available mobile bearer channel, i.e., free data connection in background like WiFi, 3G, GPRS, SMS, USSD etc.

  • the local number assigned to subscriber 102 can be a number in another country that is different from the country where subscriber is currently present.
  • the Smart Dialer uses a regional local number if there is no local country number available. The regional call will still be cheaper than the original call by mobile operator. For example, if subscriber 102 goes to UAE and tries to call India, although there is no UAE number to call, gateway 120 will connect the call to a local number in Africa first before gateway 120 sends the call to subscriber 102's original India called party number. Calling through local India number will turn out cheaper as mobile operators' charges call to India is more expensive than a call to another GCC country while being in UAE.

  • Use Case 1 Subscriber 102 (say A) is in India and wants to call his friend B in the U.S (United States of America). In this case when A dials using Smart Dialer then the call first goes to local POP in India which provides a DID number (local number), and then gateway 120 (i.e., RCS hub) forwards this call from local Indian number to the dialed US number of B. This results in a cheaper call for subscriber A as compared to the charges mobile operator would have charged for this international call. In this case subscriber A only has to pay local call charges to the local Indian DID number plus some charges for using the Smart Dialing service.
  • DID number local number
  • gateway 120 i.e., RCS hub
  • Use Case 2 Subscriber 102 (i.e., A) travels to U.S. and calls back to his friend C in India.
  • A uses Smart Dialer service to call C, then he simply dials the Indian number for C from his address book, however, the call will go through a local POP in U.S. that assigns subscriber A a local U.S. number (DID) that is mapped to the Indian number of his friend C.
  • Gateway 120 i.e., RCS hub
  • RCS hub then forwards this call from local U.S. number to the dialed number in India. This results in cheaper international call charges and subscriber A only has to pay local roaming charge call charge plus the non-roaming international long distance charge, which is often cheaper than roaming international call charge.
  • Use Case 3 Subscriber 102 (i.e., A) travels to U.S and changes to a local U.S. SIM and then tries to call his friend C in India.
  • A since the SIM has changed, in order to use Smart Dialer service, A first has to login to his Smart Dialer account (using his India account credentials) to map the new U.S. SIM number to his old Indian SIM number. Then when the MO call is initiated through Smart Dialer, gateway 120 assigns the local U.S. number that was assigned to A's Indian number (in use case 2) against to the new U.S. SIM also. This means that same mapping that was done before can be used again. However, as an extension of this use case, if A travels to U.K. (United Kingdom) and then dials out his friend C's Indian number, then gateway 120 will assign a new local U.K. number to A before forwarding his call from U.K. number to Indian number of C.

  • the address book backup done by gateway 120 also provides the subscriber 102 with an option to restore his address book in case his handset is lost or he changes to a new handset or SIM.
  • the subscriber 102 can use his Smart Dialer login credentials either through web interface or client application installed on his mobile device to restore his address book backup that is stored in gateway 120.
  • gateway 120 facilitates providing Virtual Home Environment (VHE) to automatically correct the dialed number based on the subscriber's country.
  • VHE Virtual Home Environment
  • the stored entry in gateway 120 automatically provides VHE (i.e., short code and call correction) when subscriber 102 is roaming either with his home SIM/device or a visited SIM/device. This eliminates the need to store device mapping for the corrected number.
  • the gateway 120 is aware of subscriber's 102 home location from his account credentials and his visited location from the mapping entry. For example, if a US subscriber has an address entry + 19256161056, then when this subscriber moves to HongKong and dials the number directly it fails. However, if using Smart Dialer application, then gateway 120 will provide the correct number of +19256161056.
  • gateway 120 replaces the IAC (i.e., 01 1) by the IAC of the current country if the dialed number does not have an IAC of the current country (i.e., India, which is 00 or +) nor an IAC of the home country (i.e., the United States, which is 01 1), then if the dialed number has home country code (i.e., 1 for the United States), add IAC (i.e., 00 or +) of the current country (i.e., India).

This allows the subscriber 102 to use a local SIM (from visiting country) and take benefit of roaming rates as well as international call rates. Further, in another aspect, when a new SIM is used, gateway 120 prompts a new MSISDN to be added to the smart dialer address book mapping with local numbers. An address book entry mapping with a local number of a country can be associated with multiple MSISDNs or phone numbers of the same country for different countries. In accordance with various aspects of the present invention, subscriber 102 can receive calls on his home number (SIM / MSISDN) when he changes SIM at a visiting country.

  • subscriber 102 will be prompted by gateway 120 when he swaps a visiting country SIM. For example, he will be asked if he wants to still receive calls on his home number. If yes, gateway 120 will allocate subscriber 102 a new home local number to have his old (original) home number forwarded to this new local number in order to receive calls on his device with local visiting country's SIM. This new home local number is hereinafter referred to as Home- Forward-To-N umber (HFTN).
  • HFTN Home- Forward-To-N umber
  • subscriber 102 will need to use his home country SIM or device. Also, he will not be able to receive SMS on the home number in a new SIM / device. For that subscriber 102 will have to put home SIM in another device for just receiving SMS (normally incoming roaming SMS are free).
  • subscriber 102 uses a visiting country device with a local SIM while keeping his old (original) home device and old home SIM. Then, with the new device, he has Smart dialer installed and he can request a new home number to be forwarded to if subscriber 102 has not been assigned such a number. He can then perform call forwarding on the home number to the new home number, i.e., HFTN.

  • the HFTN is mapped to the subscriber's home number.
  • the HFTN is mapped to the subscriber's visiting country number.
  • This alias number allows subscriber 102 to screen calls and receive voicemail which can then be translated as texts to be delivered to subscriber 102's handset.
  • the Smart Dialer has a configuration option for caller ID as an alias number or as the caller ID of the device/SIM. When the call reaches the Smart Dialer hub (i.e., gateway 102), the configuration is used to dictate which caller ID to call out.
  • the Smart Dialer gateway 120 can automate the call forwarding through the Smart Dialer gateway 120 when it is on a SS7 network (e.g., via the RCS hub).
  • the Smart Dialer can automatically set call forwarding for subscriber 102's home number to his HFTN via SS7 signaling. This action can be triggered, whenever there is a local SIM at a visiting country being used via Smart Dialer, the first time he will be prompted if he wants to have his home number to be forwarded to the new SIM. If yes, and if no HFTN assigned yet, he will be given one HFTN; otherwise, the Smart Dialer will automatically sets the home number to the HFTN. In such case, subscriber 102 can cancel the call forwarding via Smart Dialer anytime he wants.
  • the Smart Dialer service deals with unknown caller ID issue. Due to limited resources of DNIS, DNIS mapping is indexed by caller ID.
  • the Smart Dialer gateway 120 offers a separate pool of DNIS which is also shared by all subscribers but is not permanent for a particular subscriber. This pool will only allocate one DNIS at a time to one called number of one subscriber only on a per call basis that expires after a configurable time, e.g., in 5 minutes. In this case, subscriber 102 can request on-demand for a dialed number for a temporary DNIS. This request is then communicated via a data channel to gateway 120.
  • the mapping is optionally stored on the device side since it is only a short time, e.g., 5 minutes. If it is stored locally for a short time, subscriber 102 can dial normally the called number without any need to remember the temporary DNIS number.
  • the temporary DNIS mapping to called number however is always stored at gateway 120 (and/or its associated RCS hub) that also expires after a configurable time, e.g., 5 minutes. When the temporary DNIS is dialed, the call will reach the Smart Dialer related RCS hub, which can then reconstruct the originally intended called number.
  • the same DNIS might be used by other subscribers to map their own called number but they are distinguished by each subscriber's caller ID. Now this mapping may create problem if subscriber's caller ID is not sent.
  • the known solutions like Google Voice deal with this situation by simply dropping such a call without caller ID. This problem may not be present for US subscribers as caller ID is always sent. However, this may be a bigger problem where some countries (e.g., Hong Kong) do not allow for sending caller ID. For example, in HK off-net calls for international inbound roamers do not transmit caller ID, i.e., calls made by inbound roamers at a network to an outside network local numbers will not send caller ID. However, such cases are extremely rate. Also, in cases where the caller ID blocked, it is still sent over network but not displayed to the recipient.
  • the Smart Dialer service allows for call back services.

  • Smart Dialer gateway In yet another aspect of the present invention, some home operators charge a flat retail roaming rate. In such cases a roaming subscriber using Smart Dialer to call out with a local number will not save any money. In fact he may have paid more for the international call leg provided by Smart Dialer RCS. To overcome this issue, Smart Dialer gateway also maintains home operator and destination countries / operators to see if there are any arbitrage rate advantage between calling a local number and calling an international number when the home subscriber roaming in the destination, taking into account of the additional IDD leg of charge by Smart Dialer RCS.
  • the Smart Dialer gateway 120 When a smart Dialer subscriber makes a smart dialer call as a roaming user at a visiting country where there is no arbitrage benefit for the call, the Smart Dialer gateway 120 does not generate a local number (DNIS) and its associated mapping. Instead it returns a message to subscriber like "Because the retail charge of your home operator may be the same for whatever roaming calls you make, it is advised to use Roaming call back or use a visiting country device or SIM to make the call. To continue please press 1.". If the user indeed continues the call by pressing 1, the call at least goes through Smart Dialer gateway 120 and shows the caller ID configured at gateway 120, which could be an alias or screening number of subscriber 102. Since gateway 120 cannot guarantee the accuracy of the home operator retail roaming rate information, the call might still be cheaper that a normal dialed international call.
