FIELD OF THE INVENTION

The present invention generally relates to mobile communication. More specifically, the invention relates to enabling local data services while roaming.

BACKGROUND OF THE INVENTION

Roaming traffic contributes a significant percentage of an operator's revenue and even a better percentage of the operator's margin. With increasing competition and regulatory control, operators are being more pressured to increase their roaming revenue. As the global mobile roaming market business model is evolving, the industry understands the strategic importance of roaming to operator's revenues and profit margins and is adapting various newly proposed regulations. The operators understand that they must develop strategies for driving the number of roamers and roaming usage, while lowering tariff rates. Mostly, the roaming revenue is contributed by voice calls based revenue and less revenue contribution is due to data services. Around 70% of global mobile data users do not use data services when on roaming. Hence, data roaming is currently underutilized by a factor of 25 times despite significant uptake with much reduced retail pricing and 10% increase of data roamers.
This situation would is exacerbated with the increasing adoption of smartphone and 4G technologies. Data roaming is still the primary source of customer complaints and comprehension as it is difficult to count volume of data usage on smartphone applications given the variety of the background running usage; while voice and messaging can be easily controlled and understood by the customers via CDRs.
Gone are the days when data usage used to be a luxury option. Now, it is a necessity of everyday use of mobile phone. In fact, it is the essence of keeping in touch these days given the popular adoption of social media platforms. It is also an increasingly important source of exchanging valuable information and conducting e-commerce.
In accordance with the foregoing, there is a need in the art of a system, a method, for creating a solution that gives an operator the ways to leverage the ecosystem of partnering operators to enable a user use data services while roaming, at competitive rates, with the aim of simplifying user's experience and maximizing roaming revenue for participating operators.

SUMMARY

The present invention is directed towards a communication exchange system where an ecosystem of operators having at least one VPMN and optionally an HPMN are connected to a gateway/exchange that facilitates local data services for users. These users are roaming in the VPMN over existing roaming relationship between VPMN and their HPMN. The local data services are facilitated by configuring an Access Point name (APN) of these users. The communication exchange systems also includes an interface that maintains a bi-directional connection with the gateway to exchange information related to the roaming services, and a bi-directional connection with users via their mobile devices' user interface.
The present invention is also directed towards providing a method for facilitating local data services for the users. The gateway/exchange receiving a location update message of the users. The gateway is connected to the ecosystem of operators, having at least one VPMN and optionally an HPMN. The gateway configuring APN of the users who are roaming in the VPMN, wherein the APN is configured using an interface that maintains a bi-directional connection with the gateway and users' mobile devices' user interface.

DETAILED DESCRIPTION

In the following description, for purposes of explanation, specific numbers, materials and configurations are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one having ordinary skill in the art that the present invention may be practiced without these specific details. In some instances, well-known features may be omitted or simplified, so as not to obscure the present invention. Furthermore, reference in the specification to “one embodiment” or “an embodiment” means that a particular feature, structure or characteristic, described in connection with the embodiment, is included in at least one embodiment of the present invention. The appearance of the phrase “in an embodiment”, in various places in the specification, does not necessarily refer to the same embodiment.
The present invention provides a system and a method for facilitating local data services for a user of a Home Public Mobile Network (HPMN) roaming in a Visited Public Mobile Network (VPMN). In accordance with various embodiments, the present invention provides a method and system providing the user a facility to use data services even while roaming but charged at local rates.
FIG. 1 illustrates a system 100 for facilitating the local data service for roaming users, in accordance with an embodiment of the present invention. A user 102 of HPMN 104 (from home country) is roaming in a VPMN 106 (from visiting country). The user 102 is connected to a VPMN VLR 108, when it is roaming outside HPMN 102. The system 100 includes a gateway 110, hereinafter, interchangeably referred to as communication exchange 110 or exchange 110 that facilitates local data services for user 102 while in VPMN 106, in accordance with various embodiments of the present invention. The user 102 uses a smartphone device that has a provision to have a software interface/software application that helps in maintaining a bi-directional connection with gateway 110 to exchange information related to the roaming services, and a bi-directional connection with user 102 via his/her mobile devices' user interface. For sake of representation only two operators (HPMN and VPMN) are shown, however, in various embodiments of the present invention, exchange 110 works with an ecosystem that has multiple operators (HPMNs and VPMNs), who would like their subscribers to use this facility of local data services. In further embodiments the scenario of only VPMN operators participating is also explained.
In one embodiment of the invention, VPMN VLR 108 is connected with an SGSN-R 112, which is further connected with STP-R/DEA 114, via SS7 protocol. The exchange 110 is connected with STP-R/DEA 114 via IP in monitoring mode. User profile data corresponding to user 102 is stored in HPMN HLR-H 116. The signaling corresponding to user 102 is routed using STP-H 118. The signaling between HPMN 104 and VPMN 106 is carried using SS7 signaling architecture. The signals exchanged between HPMN 104 and VPMN 106 are MAP based signals.
For the sake of representation, system 100 represents network elements from both LTE and GSM networks. HPMN 104 including HSS/HLR-H 116 connects via a STP-H/DEA 118 to an MME, which is further connected to an MSC-R/VLR-H in HPMN 104 via BSSAP+ protocol. These network elements communicate with each other over a Signaling System 7 (SS7) link.
It will also be apparent to a person skilled in the art that HPMN 104 and VPMN 108 may also include various other network components (not shown in FIG. 1), depending on the architecture under consideration. It will also be apparent to a person skilled in the art that various components of HPMN 104 communicate with VPMN 106 using various signaling techniques including, but not limited to, SS7, SIP, IP, ISUP etc.
In accordance with various embodiments of the present invention, the exchange 110 is a B2B2C cloud-based electronic trading service that is built on an clearing exchange with an ecosystem of mobile operators (considered as merchants) that allows users such as user 102 through a software front end interface (without requiring them to change their mobile device and/or SIM) to sell and buy a local rate data package for use of a roaming or local device in a mobile operator of the ecosystem. In addition to cross operator trading between users of different networks, the users of a joining operator can even buy and sell local rate data packages in the same network. This electronic market place simplifies the user experience by enabling a pure smartphone (such as, but not limited to iOS based devices, Android based devices) application interface for the trading service.
In accordance with various embodiments of the present invention, the exchange 110 provides a seamless experience to user 102. A roaming user or a local user with a smartphone (as defined above) with an unchanged HPMN 104's SIM using an application downloaded from an application store registers an account with the trading service, provided by exchange 110. Now, through this application, the user 102 can buy a local rate data package offered by a local mobile operator with a stored wallet or a payment method. In accordance with several embodiments of the present invention, the interface enables payments related to sale or purchase of data packages, using at least one of mobile wallet, PayPal, Credit Cards, Debit Card, wire transfers, Near Field Communication (NFC) payments, WePay, Alipay, Pay™, and online payment systems. Once the user 102 has bought a data package, the data package can be activated on a scheduled time, on registration automatically or on demand manually. The user 102 may also manually select the mobile operator (via the application the application or via the user's mobile interface) or the user 102's phone is automatically steered to the desired mobile operator.
An enterprise service administrator (local or international) using the software interface (i.e., the application on user's mobile or a web interface or just a desktop client) registers an account with the trading service and can then buy an individual or group local rate data package on the trading platform for an individual or group of mobile devices (such as a company's employee group, M2M and Internet Of Things) the enterprise manages. Once a device is part of a bought package, the device's local usage can be activated on a scheduled time, on registration automatically or on demand remotely over the air. The device may also be configured for the selected mobile operator remotely over the air or be automatically steered to the mobile operator. Individual device's usage and monetary spending can also be controlled by the administrator.
User 102 with a smartphone with an unchanged home operator SIM using an application on his smartphone registers an account with the trading service. Now through the application, user 102 can sell a portion of his unused local rate data package bought on the trading platform to another roaming traveler or a local user. The application informs the user how much data used so far and how much data is unused on its current data plan. Once the portion is sold, the user would be credited with the money in its stored wallet.
A mobile operator using the interface registers an account with the communication exchange 100/trading service, and can price and sell a local rate data package for one or more devices on the trading platform. Once the portion of package is sold, the operator account would be credited with the money in its stored wallet. The buyer could be a local user or a roaming user or local enterprise or international enterprise.
An enterprise service administrator using the interface registers an account with trading service 110 and can sell a portion of the enterprise's unused local rate data package bought on the trading platform. The software interface informs the administrator on usage of the data. Once the portion of data package is sold, the enterprise account would be credited with the money in its stored wallet. The buyer could be a local user or a roaming user or an enterprise.
It will be apparent to a person skilled in the art that the trading service 110 of local rate data plan can also be used by locals within the same operator or roaming devices between operators of national roaming and international roaming. Moreover, an operator merchant normally only sells data packages although there is no system restriction for the merchant to buy data packages as an enterprise too. However, non-operator merchant seller is restricted to sell only data packages that are bought via the trading service.
FIG. 2 represents a flowchart for implementing the communication exchange for local data service, in accordance with an embodiment of the present invention. At step 202, gateway 110 receives a location update message of user 102. Thereafter, at step 204, the gateway 110 modifies APN of user 102 to enable his/her local data services in VPMN 106. The gateway 110 enables configuration of APN by enabling Local Break Out (LBO) at HLR-H 116 profile of user 102, who is registered at gateway 110.
FIG. 3 represents a flow diagram for implementing the communication exchange in monitoring mode, in accordance with an embodiment of the present invention. In this case HPMN 104 is not a participating operator as part of the ecosystem of operators, then user 102 will not have LBO APN in its registration at VPMN 106, then exchange 110 dynamically adds such as an APN of users 102's profile. In such case VPMN 106 needs to have gateway/exchange 110 functioning in monitoring mode to monitor incoming roaming users' data registration at SGSN-R 112, and then dynamically add the LBO APN profile to user's 102 profile at SGSN-R 112, if user 102's IMSI has a non-expired data package. VPMN 106's own subscriber need would have allowed LBO APN in all its subscribers' profiles, provided VPMN 106 allows trading by its own subscribers, it being a part of this ecosystem for trading services. VPMN 106 updates its Domain Name Resolution (DNS) to LBO APN to facilitate an incoming data session request on LBO APN to be resolved to local GGSN/PGW.
FIG. 4 represents a flow diagram for implementing gateway 110 in proxy mode, in accordance with an embodiment of the present invention. As shown in the call flow, since gateway 110 is made as a proxy to SS7/Diameter messages location update messages, in which case still not all SS7/Diameter messages need to be proxied through gateway 110. In this case, it is possible to handle situations where the roaming user 102 might not have a data roaming service enabled by HPMN 104. In this case, when the location update message is proxied thru gateway 110, if the IMSI does not have an unexpired data package at the network, then the signaling is simply bypassed by gateway 110 and subsequent return or exchange messages will not involve gateway 110.
Otherwise, the return message from HPMN 104 will go via gateway 110. If there is a profile returned, gateway 110 modifies it to include the LBO APN and VPMN 106's address allowed. If the return message is rejecting the registration, gateway 110 will ignore the message and instead return a profiled message that includes the LBO APN and VPMN's address allowed. This embodiment is also applicable in case HPMN 104 is doing steering on the data registration. Once the data registration is granted success, it also renders the GSM/voice steering useless. In accordance with various embodiments of the invention, the LBO APN for Release 4 message can just be operator identifier replacement (APN-OI replacement) rather than network identifier change of an APN. In this way, no device client change of APN would be required.
FIG. 5 represents a flow diagram for implementing the communication exchange 110 in proxy mode for hard steering, in accordance with an embodiment of the present invention. In order to allow an HPMN operator for doing hard steering with VPMN 106 against GSMA guidelines, user 102 must be informed the whole consequence, including but not limited to:

- The home services including voice, messaging and data would not be possible
- There would not be VPMN voice and messaging either except data services

As shown in the call flow in FIG. 5, user 102 would opt in for such a situation via the communication exchange 100. The communication exchange 100 would inform the gateway 110 for the opt-in where gateway 110 would be on the signaling path of SS7 and Diameter as a proxy. If gateway 110 observes hard steering from HPMN 104 after authentication are noted to be successful, it would complete the GPRS/Data registration gateway 110 with LBO as the only APN, and for GSM registration if CSFB/combined location update is observed. However, the user 102's profile would be restricted for any calls and message services at either VLR/VMSC-R or MME/SGSN-R 112.
In accordance with another embodiment of the present invention, in case HPMN 104 doesn't have a roaming agreement with VPMN 106, user 102 must also be informed the whole consequence, including but not limited to

However, in this embodiment, unlike Hard-steering where there is still authentication success, to avoid fraud, there is a need for a sponsor authentication service where the Send Authentication (SAI) is sent on a sponsor network gateway. Once this is achieved, the solution can be applied same as the hard steering embodiment explained above.
FIG. 6 represents a flow diagram for implementing end to end interactions for activation of local data services, in accordance with an embodiment of the present invention. As explained in above embodiments, the interface is software installed on user 102's mobile device via an application store. The smartphone application can also operate on a USSD and SMS channel. The functions of this interface vary according to the role of user 102. An operator administrator requires more information as negotiated with the operator. User 102 (e.g. employee) or device (e.g. M2M) under the control of an enterprise administrator can incorporate a policy control element that can be controlled by the administrator. The control element might also be operable for the individual device user with a front end interface based on the policy.
In accordance with various embodiments of the present invention, user 102 has multiple mobile accounts and trade (buys or sells) data packages on the currently activated account (or default account). For each account, user 102 can also configure threshold alert, remaining balance alert, top up alert etc. However, each mobile account must be verified at the time of registration via the corresponding SIM as HPMN 104 of user 102 needs to have a roaming relationship with VPMN 106. If this is not verified, and HPMN 104 is based on user 102's entry at the registration which is wrongly input, then if the data package of VPMN 106 bought at trading service 100 cannot be used due to no-roaming agreement, the liability would be on user 102 although user 102 could still sell the data package.
In accordance with another embodiment of the present invention, user 102 may also buy or sell data packages for its own use and might require administrator approval, depending on the enterprise policy. For example, an enterprise might have a group plan for US AT&T, but an individual employee might need to go to South Africa and buys a local data package there but need to be approved by the company.
As show in the call flow in FIGS. 6 a and 6 b, user 102 may receive notifications for data usage alerts, sale expired alerts, top up or switch back home data routing alerts etc. via email, web notification box, or smartphone app/interface. The interface can also store and update usage of each purchase plan locally. Whenever there is a country change or network change, the interface can verify if there is a local package or still unused for the country. If there is, but the registered operator is not the local operator of the package or the LBO data session has not been set up properly for the local operator of the package, then the interface can alert user 102 to do a manual switch to package VPMN 104.
At the time of the switch, the interface will be used to configure (or swap in) the LBO APN profile at the device and manually select the right network (i.e., VPMN 106) to register. The interface may also be able to automatically (e.g. in case of application based on Andriod or iOS) detect the visiting country and package balance available to configure the LBO APN profile and to select the corresponding local network and data session. In case, a new data session on an operator is not using a LBO profile either because the smartphone software operating system informs the interface or the interface did not get a notification from the operator backend, then the interface can also alert user 102 for a manual action on selecting the network and to restart the data session again if there is a package (and optionally alert user 102 of home roaming if there is no package or package expired or run out and set the interface to switch to home APN profile manually or automatically).
It will be apparent to person skilled in the art that when the interface is manually switching to the operator network with a bought local rate data package, HPMN 103's steering system will be overwritten. Based on the GSMA guidelines BA 30 and IR 73, user 102's manual selection must be honored and overwrite steering preferences. As mentioned in earlier embodiments, if VPMN 106 is forbidden or no roaming relationship, it would not be presented to user 102 in the market place for trading of data packages. Upon returning home or country where there is no visiting country data package balance available, the interface can be alerted to manually or automatically switch back to the HPMN (e.g. APN) profile.
In accordance with an embodiment of the present invention, in order to implement this trading exchange, HPMN operators are also part of the operators' ecosystem. There are several ways in HPMN operator can support this trading exchange. In one such embodiment, FIG. 7 represents a flow diagram for implementing activation of local data services via USSD channel. HPMN 104 provides a USSD interface for menu selection for its subscribers (i.e. user 102) already outside the country or simply just for own subscribers making a purchase of data packages without incurring data (or data roaming) charges. HPMN 104 defines HPMN USSD service code at HLR-H 116 and a USSD gateway. There is an IP interface between USSD Gateway and Exchange Service/Gateway 110. HPMN 104 provides to the interface with subscriber HPMN network, MSISDN, visiting network etc. and gateway 110 presents a corresponding menu dynamically based on the user 102's HPMN network and the visiting country (based on VPMN 106). Similar concept to USSD, SMS channel can also be used. However, due to speed impediment in using SMS and still incurring roaming cost, the embodiments of the present invention may be implemented using SMS, in some situations.
As explained in various above embodiments of the present invention, there is a business case for operators of the ecosystem to benefit from this trading exchange. FIG. 8 represents a flow diagram for overall business model and its key transactions, in accordance with an embodiment of the present invention. The basic business model of the service is that the exchange 110 takes a transaction fee of a transaction. Exchange 110 acts as a broker or middle man that handles all the transactions and payments. All monetary exchange would be prepaid and based on a cascading model. The seller decides the price of data package. The buyer of a transaction by a seller pays exchange 110 as a broker. Exchange 110 pays the seller minus the transaction fee. Exchange 110 shares the fee with the seller's mobile operator and the mobile operator of the buyer if the buyer's mobile operator is a HPMN operator (like HPMN 104) of the ecosystem of the trading communication exchange. Exchange 110 is liable for the seller and the buyer is liable for exchange 110. Because all transactions are prepaid, the risk for exchange 110 is the least. Although there is no financial clearing per se, the seller's operator can do data clearing with the exchange for reconciliation, whose success can be based on an agreed margin of error (e.g., 1%-3%) and a settlement procedure on any failed reconciliation.
It will be apparent to a person skilled in the art that the trading exchange is not operating as a MVNO model but as simply an electronic retail distribution model for operators tailored for locals, travelers and enterprises without a new SIM for user 102. Although it is trading local rate data service, it does not offer customer care to end user communication service. This is very similar to other trading exchanges like eBay, Priceline, selling car rentals/hotels where these trading services do not provide customer care for the hotel or car service. As a result, the customer care for end user communication service is still with the serving or home mobile operator. This is similar to car rental bought through Priceline where car service is still a responsibility of the car rental company.
Notwithstanding, trading exchange 110 has its own customer care for handling complaints about the trading service rendered by mobile operator at exchange 110, similar to customer care in Priceline or Hotel.com. As the users and merchants' financial transactions are going through the exchange 110 as a broker, similar to issuing/acquiring banks of credit cards for charge backs, the trading service would also handle refunds in case the user service is not rendered for the paid packages. In the case, the refund is cascaded as well. The trading service would refund the users and the operators/merchants would need to refund the trading service including all transaction fees.
In accordance with one embodiment of the present invention, if the seller is a user in addition to an operator, then the refund process would only be done by exchange 110 as the user might lose opportunity to sell to another buyer and the user is not at fault for any service issue. FIG. 9 represents a flow diagram for sample transaction process in activation of local data services, in accordance with an embodiment of the present invention. A seller puts a data package on sale to exchange 110. Thereafter, exchange 110 validates the data package and reserves it if the seller is user 102. If the sale is expired, exchange 110 re-deposits the data package pack if the seller is user 102 and alerts the seller. If there is a buyer, the buyer money would be deducted from its account and alerted for the transaction; and the seller account would be credited including commission for the trading exchange, and VPMN and HPMN for the transaction fees etc.
After the buyer activates the local package and visits the country, HPMN 104 helps to steer the roaming user 102 to the operator of the data package. The buyer accesses VPMN 106 where credit control is made with exchange 110 and alerts are communicated with exchange 110 and the buyer. FIG. 10 represents a flow diagram for sample refund process in activation of local data services, in accordance with an embodiment of the present invention. The buyer complains about unable to render the service on the data package bought at VPMN 106. Thereafter, exchange 110 validates the complaint with VPMN 106 to see if there are any network attempts and failure to establish a data session. Of course if the buyer is found not to have made such a trace, refund would not be granted. Subsequently, exchange 110 asks VPMN 106 for a refund if it is the seller including transaction fees from HPMN 104 and VPMN 106. Finally, exchange 110 refunds the buyer.
The various embodiments of the present invention, are based on a basic architecture involving three key components, trading exchange, software interface on user's mobile device, and finally the participating operators. FIG. 11 represents a flow diagram for implementing basic architecture for activation of local data services, in accordance with an embodiment of the present invention. The software interface interacts with the Exchange Service over a bidirectional or peering IP interface, which means either party can initiate request/push. The software application can obtain a store market place from the exchange 110. It can notify exchange 110 on any activation by user 102. Thereafter, exchange 110 can also push notifications (e.g., data usage alerts, threshold alerts) to the software interface. Exchange 110 interacts with operator backend over also a bi-directional or peering IP interface which means either party can initiate request/push. Subsequently, exchange 110 can send the operator info on a user bought or sold data package to enforce/update a credit control on user 102. The operator can check usage authorization, push notification (e.g. data usage alerts, threshold alerts) to exchange 110.
In accordance with various embodiments of the present invention, the trading exchange can also be extended to automatically select a data plan and sells an unused plan for a subscriber should he opt-in so based on the criteria he sets. In accordance with one such embodiment of the present invention, FIG. 12 represents an indicative user interface to configuring an auto-buy of local data services on users' device. To automatically buy a plan, user 102 may preset a day-plan, 3-day-plan, a week plan, or a month plan. He can also define criteria based on coverage, speed, price and quality either based on simple checkbox or based on a percentage weight in total of 100%. There is also a recurring option for user 102 to check so that if the current plan is finished and the subscriber is still in the country.
This automation is triggered by the software interface detecting user 102 is registered in a network in a country that trades data plan in the trading exchange. Then the software interface can communicate with the trading exchange via USSD or WiFi to avoid incur roaming charge. When the current plan is used up or about to be used up, the trading exchange would inform the software interface via SMS or data channel of the bought data package. If the software interface detects the user 102 is still registered in the country, and the software interface informs the trading exchange via USSD or WiFi to avoid incur roaming charge. If user 102 has opted in for the recurring option, another plan would be bought. FIG. 13 represents an indicative user interface to configuring an auto-sell of local data services on users' device, in accordance with an embodiment of the present invention. To automatically sell an unused plan, user 102 sets the condition based on detection of him reaching home or another country or just based on his currently daily usage rate to sell unused data package. The price would be defined by the trading exchange 110 to the best of its capability. The automation is triggered by software interface detecting user 102's mobile is registered in a network in a home or another country or based on the daily usage rate at the trading place.
In accordance with various embodiments of the present invention, the exchange 110 manages a wallet account for each registered user similar to Paypal or Amazon Payment due to transactional funds similar to Ebay or Paypal. Like the Paypal the account could be backed up by credit card or bank transfer automatically when the balance is running out. Also like the Paypal, the balance could be cashed out directly via a bank card or transfer back to a bank account.
In accordance with several other embodiments of the present invention, the trading exchange can also be extended to auctioning of data packages, similar to Priceline or Ebay. The present invention allows user 102 to be a seller other than an operator, the auction allows the following possibilities:
a) The buyer can name own price
b) The buyer can bid for a deal
c) The seller can provide an optional minimum price and an optional definite sell price for buyers to bid (within a bid period)
d) The seller can just present a non-negotiable pricing
e) There can be multiple operators' offering to choose.
However, the auction extension in the non-operator merchant seller case continues to be restricted to packages bought via the trading exchange.
In accordance with an embodiment of the present invention, the data package bought could be application based charging. For example, only Facebook is free with the bought data package. Or the data package would be unlimited for the fixed price but with speed downgraded to 2G. VPMN 106 could also allow a URL access for free for the trading exchange 110. This will be automatically updated into the software interface for accessing the store front when the user 102's device is accessing the network.
In another embodiment of the present invention, the trading exchange can be extended to support VoIP by offering multiple number VoIP service where a member mobile operator of the ecosystem can contribute a local number for roamers or non-member customers to permanently or temporarily use for making or receiving calls and SMS. Moreover, the trading exchange can bind incoming calls to a user's number of the member mobile operator over IP to reduce roaming cost.
It yet another embodiment of the present invention, a travel enterprise (e.g. airline, hotels, tourist business including shopping and restaurants etc.) software application is built on the trading exchange API so that the cost on the usage of user 102 on the software application in roaming or local environment including VoIP calls can be covered by the enterprise for the trading exchange. In this case, the enterprise does the B2C advertising and own services including free or sponsored data roaming and VoIP calls. The enterprise also does cross advertising and B2B trading among related enterprise on the exchange, for example, Chase Bank advertise on Nike App, hotels on airline apps, car rentals on hotels etc. In a continued embodiment of the present invention, OTT apps such as Skype, Facebook, WhatsApp, Google voice etc. are built on the trading exchange to leverage a sponsored data plan in return for advertising revenue. Moreover, all the buyers' traveling destinations, data usage statistics, buying expense etc., and all the sellers' unused data amount statistics and selling operators etc. provide valuable analytics for advertising, traveling enterprise apps and targeted marketing of further trades.
In other embodiment of the present invention, the trading exchange tracks and report application protocols and URLs etc. based on DPI support of VPMN 106. In particular, VPMN 106 provides foot fall data intelligence on travelers, while the trading exchange provides travelers profiles around the world. The combined profile allows traveling enterprises to form targeted advertising on different enterprise applications. If HPMN 104 also participates, more subscriber profile data (on local usage and worldwide roaming usage) is used for better targeted advertising.
However, that all privacy issues are protected in the following ways
1) Only generic profile data (e.g male more than 50 years, spending 50 USD a day etc.) is collected and cannot be related to an individual user (e.g. John P. of ABC company)
2) While the generic profile data is collected and shared across enterprise apps for targeted advertising, it is not shared for sign on to avoid correlation-ship with individuals.
The analytics services such generated are used by enterprise including M2M and IoT. In such cases, user 102's mobile's software interface is configured by enterprise admins to track and report all usage information.
It will be apparent to a person skilled in the art that when LBO is chosen, software application residing on user 102's mobile device would configure/select the LBO APN for the device data access profile. When home routing is chosen, the device client would configure/select back the home profile for the device data access profile. In general, LBO APN breakout does not interfere with other services such as CSFB and VOLTE. Nevertheless, for CSFB, LBO is not a concern, while for VOLTE another APN IMS used for local breakout. As devices allow multiple APNs and local breakout sessions, there are no interferences. As VOLTE is still considered as voice roaming even though it is a data service, it would not incur local data package consumption.
In yet another embodiment of the present invention, since the trading exchange operates based on MSISDN, number portability works when changing operators except when the new operator has no roaming relationships with the visiting operator of the bought package. User 102 still will be liable for payment in this exceptional case, similar to no-show cancellation on non-refund, e.g. trip cancelled. However, unlike no-show cancellation policy, user 102 can sell the unused package to other users through the trading exchange. If user 102 changes numbers either on existing or new operators or the user 102 intends to use another SIM, user 102 will still be liable for the payment. However, user 102 can transfer the data package on its new number without incurring any charges. User 102 can also sell it but that would incur additional charges.
In accordance to another embodiment, the number portability feature is used to implement gifting. Unlike number change, the gifting might not verify the gifted party's number although to avoid mistakes, it is recommended to verify it. The software interface manages multiple SIMs accounts to allow user 102 to swap SIMs, as the software interface can switch accounts as buyers and sellers for the correspond SIMs. However, each SIM can only have one account, verified at the time of registration. Once registered, user 102 is free to use the trading service using any SIMs as it can switch accounts on line for trading data packages on the selected account.
In accordance with yet another embodiment of the present invention, the gateway 110 facilitates local data roaming for users using multi-IMSI SIM. The new multi-IMSI SIM has several static IMSIs based on partnership between operators.
It will be apparent to a person skilled in the art, that the present invention can also be applied to Code Division Multiple Access (CDMA)/American National Standards Institute #41D (ANSI-41D), and various other technologies such as, but not limited to, VoIP, WiFi, 3GSM and inter-standard roaming. In one exemplary case, a CDMA outbound roamer travels with an HPMN CDMA handset. In another exemplary case, the CDMA outbound roamer travels with an HPMN GSM SIM and a GSM handset. In yet another exemplary case, GSM outbound roamer travels with an HPMN CDMA RUIM and a CDMA handset. To support these variations, system 100 will have a separate SS7 and network interfaces, corresponding to both the HPMN and VPMN networks. It will also be apparent to a person skilled in the art that these two interfaces in different directions may not have to be the same technologies. Moreover, there could be multiple types of interface in both directions.
