## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims benefit of U.S. provisional patent application Ser. No. 61/779,543, filed Mar. 13, 2013, and provisional patent application Ser. No. 61/745,926, filed Dec. 26, 2012, which is herein incorporated by reference.
BACKGROUND OF THE INVENTION
1. Field
The invention is related to systems and methods for terminating communications to a telephony device. More specifically, the invention relates to systems and methods for routing Short Message Service (SMS) communication between mobile devices on different mobile service provider networks.
2. Description of the Related Art
Mobile telephony devices, such as cellular telephones and mobile computing devices with Short Message Service (SMS) communication capabilities, are typically provided with service from a mobile service provider. The mobile service provider typically only provides service to its customers within a defined geographical area, often only within a single country. The area served by the provider is considered the “native” service area for customers who receive mobile telephone service from the provider.
If a customer who receives mobile telephone service from a first “native” mobile service provider travels to an area outside his native service area, the customer's mobile telephone may be capable of receiving mobile service from a second “non-native” service provider that provides coverage in that location. However, because the non-native service provider is not the customer's regular service provider, the customer will be charged special “roaming” fees for receiving incoming communications and for sending outgoing communications from that location. Typically, the non-native mobile service provider charges the user's native mobile service provider for providing service to the customer's cellular telephone, and the native mobile service provider then passes those charges along to the customer as part of his regular monthly bill. This is true for telephone calls, text messages, and other forms of telephony communications.
Roaming charges can be exorbitant compared to fees charged for telephony communications within the customer's native service area. International roaming charges are particularly expensive, as the rates negotiated between carriers for overseas call termination has been at a premium.
Accordingly, the inventors have provided improved systems and methods for sending and receiving Short Message Service (SMS) communication between mobile devices on different mobile service provider networks.
SUMMARY OF THE INVENTION
Methods and apparatus for routing non-native Short Message Service (SMS) messages to a first device, the first device being assigned a native identifier and being associated with a native telephony service provider, are provided herein. In some embodiments, the method includes receiving an SMS message directed to the native identifier of the first device, determining routing instructions for the SMS message based on the native network identifier associated with the first device, and routing the SMS message to the first device based on the determined routing instructions, wherein the act of routing results in SMS messages directed to the native identifier of the first device being directed to a forwarding identifier assigned to the first device by a first non-native communication service provider.
In some embodiments, a method of routing non-native Short Message Service (SMS) messages from a first device, the first device being assigned a native identifier and being associated with a native telephony service provider, may include receiving an SMS message from the first device directed to a second device on a second communication service provider, wherein the SMS message from the first device is sent from a first non-native communication service provider and includes the native identifier assigned to the first device, determining a cost associated with routing the SMS message based on at least one of the native network identifier associated with the first device or an Internet Protocol (IP) address associated with the received SMS message, and routing the SMS message to the second device.
In some embodiments, an apparatus for routing non-native Short Message Service (SMS) messages to a first device, the first device being assigned a native identifier and being associated with a native telephony service provider, may include at least one processor, at least one input device, and at least one storage device storing processor-executable instructions which, when executed by the at least one processor, performs a method including receiving an SMS message directed to the native identifier of the first device determining routing instructions for the SMS message based on the native network identifier associated with the first device, and routing the SMS message to the first device based on the determined routing instructions, wherein the act of routing results in SMS messages directed to the native identifier of the first device being directed to a forwarding identifier assigned to the first device by a first non-native communication service provider.

DETAILED DESCRIPTION
Exemplary embodiments consistent with the present invention allow SMS communications to be handled by telephony service providers other than the native carrier associated with the subscriber device. Thus a subscriber to such non-native messaging services is able to realize lower communication costs as the messages are passed over the non-native network through the non-native network's SMS server rather than through the native carrier's equipment and network.
In the following description, references are made to a user's or a customer's telephony device. This term encompasses traditional cellular telephones, as well as mobile telephony devices that include additional functionality, such as the ability to wirelessly communicate digital data. These terms also encompass mobile computing devices that include SMS communication capabilities provided by either or both of a cellular transceiver and a wireless digital data transceiver. Examples of such devices include the Apple iPhoneTM, the Apple iPod TouchTM, mobile telephony devices running the AndroidTM or a Windows® operating system, the BlackberryTM and mobile telephones running the Symbian® operating system, and the like.
The following description also refers to terminating a telephony communication. This phrase refers to delivering text messages and other forms of text-based or video-based messaging to a telephony device. This phrase also encompasses other forms of communications that may be carried over a telephony network.
Some embodiments of the present invention provide a method, system and apparatus for terminating a telephony communication to a telephony device via an Internet Protocol (IP) such as Voice over IP (VoIP) telephony system. In some instances, the telephony communication is terminated to the telephony device through the VoIP telephony system because the telephony device is roaming, and roaming charges would apply if the telephony communication was terminated in a traditional fashion. Terminating the telephony communication through the VoIP telephony system makes it possible to avoid the roaming charges. In other instances, the telephony communication is terminated through the VoIP telephony system for some other reason, as will be explained below.
In some instances, however, such as where no other options exist, the IP telephony system might deliberately cause the telephony communication to be terminated to a roaming telephony device in a traditional fashion through native mobile telephony service provider. While this might result in the user incurring roaming charges, terminating the telephony communication in this fashion may be the only way to reach the user.
The following description provides examples of how embodiments of the present invention can be used to terminate SMS communications to a mobile telephone device via a VoIP telephony system. The mobile telephony device could be a cellular telephony or a smart phone. However, embodiments of the present invention are also applicable to other types of devices that are operable as telephones such as laptop or personal computing devices running application software that provides for telephony communications. Thus, the reference to a mobile telephony device should not be considered in any way limiting. In some embodiment systems and methods described herein can also be used to terminate SMS communications to telephony devices other than traditional mobile telephony devices.
FIG. 1 depicts various elements that may be involved in terminating an SMS communications. The system 100 comprises a first telephony network 106 communicatively coupled to a second telephony network 108 via an IP network 120. In FIG. 1, a subscriber A associated with a telephony device 102 on the first network 106 is sending an SMS communication to a subscriber B associated with a telephony device 104 on the second telephony network 108. In some embodiments, the first network 106 may be a non-native network such as a VoIP provider network running on an IP network. In some embodiments as described herein, a non-native telephony network 106 may refer to a telephony network that is not the typical service provider for a telephony device on that network. For example, with respect to FIG. 1, subscriber A's service provider for telephony device 102 may be different than the service provider associated with the first telephony network 106. For example, subscriber A may access the first (non-native) telephony network 106 via a mobile application installed on device 102. In some embodiments, subscriber A may first access a native telephony network (or other type of wireless or wired network) 107 in order to gain access to the first (non-native) telephony network 106 via the mobile application installed on device 102. In other embodiments, the first telephony network 106 refers to a telephony network that is the same service provider for the telephony device 102 on that network.
The subscriber A associated with telephony device 102 may opt in to the non-native service provider's SMS offering (e.g., an AT&T® subscriber may opt into an SMS offering from Vonage® VoIP services). The subscriber may opt in by installing a mobile application provided by the non-native service provider to facilitate the sending and receiving of SMS messages. When a subscriber opts-in to the non-native service providers SMS offering, the subscriber's native network identifier (e.g., the subscriber's telephone number) becomes associated with the non-native service providers application server 110. The non-native service provider may assign a forwarding identifier to the first device upon registration. Thus, when subscriber A sends/recieves an SMS communication, the SMS message is routed to, and handled by, non-native application server 110 rather than the traditional (i.e., native) mobile service provider's equipment that subscriber A has telephony service with.
The application server 110 comprises a Central Processing Unit (CPU) 130, support circuits 132 and a memory 134. The CPU 130 may comprise one or more commercially available microprocessors or microcontrollers that facilitate data processing and storage. The various support circuits 132 facilitate the operation of the CPU 130 and include one or more clock circuits, power supplies, cache, input/output circuits, and the like. The memory 134 comprises at least one of Read Only Memory (ROM), Random Access Memory (RAM), disk drive storage, optical storage, removable storage and/or the like. In some embodiments, the memory 134 comprises (or may otherwise be associated or communicatively couple with) an operating system 136, a registration module 138, a user information database 140, and an SMS module 142. In some embodiments, the database of user information is stored remotely on a remote server (not shown) and the user profiles are retrieved from the remote server by an subscriber identifier when needed.
The operating system (OS) 136 generally manages various computer resources (e.g., network resources, file processors, and/or the like). The operating system 136 is configured to execute operations on one or more hardware and/or software modules, such as Network Interface Cards (NICs), hard disks, virtualization layers, firewalls and/or the like. Examples of the operating system 136 may include, but are not limited to, Linux, Mac OSX, BSD, Unix, Microsoft Windows, and the like.
In some embodiments, in order to access the SMS offering from the non-native service provider, the subscriber first registers with the non-native service provider via registration module 138 on application server 110. The subscriber's mobile device identification number (e.g., the subscriber's telephone number) is associated with a subscriber ID and stored in user information DB 140. Thus, the subscriber's mobile device identification number becomes associated with the non-native service providers application server 110.
The non-native service provider may partner with a second mobile telephony provider of the second telephony network 108 to provide SMS messages to each other customers. In such a partnership, the non-native service provider may provide a list of users and their associated information from user information DB 140 to the second mobile telephony provider. The second mobile telephony provider may store the user information in a resolver database 114. The resolver database 114 may be updated in realtime, in batch mode, or at scheduled intervals via connection 160 over IP network 120.
SMS communications from subscribers that opted in to the non-native service provider's SMS offering would be routed by application server 110 to the intended recipient. The SMS message would be sent over IP network 120 via Short Message Peer-to-Peer (SMPP) protocol to SMS messaging hub 112 on the second telephony network 108. The SMS messaging hub 112 would convert the SMPP protocol received from the application server 110 to a native signalling network 118 for delivery subscriber B. In some embodiments, the native signalling network 118 may be GSM or CDMA. In other embodiments, the second network may be a VoIP network and thus the SMS message may not need to be coverted.
In some embodiments, upon receipt of an SMS message from application server 110, the SMS hub 112 may perform a look-up in the resolver DB 114 using telephone number mapping (e.g., E.164 Number Mapping (ENUM) mapping, and the like) to determine whether the subscriber who sent the SMS message is a subscriber of the partner non-native server provider. The lookup may be done to determine costs for terminating the SMS message that are charged back to the non-native service provider, and ultimately back to the subscriber. In some embodiments, the SMS hub 112 may not perform a look-up in the resolver DB 114, but rather identify the incoming message as being associated with the partner non-native server provider based on the IP address of the incoming message. The SMS message is then routed from the SMS hub 112 to message service center (SMSC) 116 and terminated at device 104. In some embodiments, if the subscriber's mobile number (e.g., subscriber A who originated the SMS message) is not stored in resolver DB 114, then signaling network 118 will be used to send the SMS message.
Similarly, FIG. 2 depicts various elements that may be involved in terminating an SMS communications originating from subscriber B on the second telephony network 108 in reply to a message, for example from subscriber A associated with a telephony device 102 on the first telephony network 106.
When subscriber B sends an SMS message to subscriber A, SMS hub 112 will determine how to route the message. As described above with respect to FIG. 1, the SMS hub 112 will perform a look-up using telephone number mapping (e.g., E.164 Number Mapping (ENUM) mapping, and the like) to determine whether the SMS communication should be routed to non-native application server 110 or to a traditional mobile operator associated with the subscriber. If the SMS message is to be routed using the first telephony network 106, the SMS message to subscribers that opted in to the non-native service provider's SMS offering will be routed to non-native application server 110 using Short Message Peer-to-Peer (SMPP) protocol. In some embodiments, the SMS message may be routed using HyperText Transfer Protocol REpresentational State Transfer Service (HTTP REST) or any other IP based protocol including proprietary protocols.
In some embodiments, for example, any SMS message from a subscriber of the first telephony network to a foreign country such as India will be routed exclusively to messaging hub 112 (via, e.g., an IP VPN connection). In those embodiments, the SMS “From” field may contain the original mobile number for the subscriber on their native network. That is, if subscriber A has their normal telephony service through AT&T®, then subscriber A's AT&T mobile number may be displayed in the “From” field. When the recipient subscriber (subscriber B) responds to said SMS message from subscriber A, SMSC 116 will check real time resolution database 114 to see if subscriber A's mobile number is registered. If subscriber A's mobile number is registered in resolution database 514, the SMS message will be routed over IP VPN to the first telephony 106. Any message originating from the second telephony network 108 to any international number will first be looked up in the user information db 140 on the first telephony network 106. If there is a match, the message will be delivered to the mobile telephony application on mobile device 102 using network 106.
FIG. 3 depicts an exemplary method consistent with the elements and features described with respect to FIG. 2. Specifically, at 302 an SMS message may be received by SMS messaging hub 112 by a second subscriber (e.g., subscriber B in FIG. 2) on a second telephony network (e.g., network 108 in FIG. 2) to a first subscriber (e.g., subscriber A in FIG. 2). The SMS message may be directed to a native identifier associated with the first device. At 304, routing instructions may be determined for the SMS message based on the native network identifier associated with the first device. In some embodiments, the routing instructions may be determined by SMS messaging hub 112 by extracting the native network identifier associated with the first device from the “FROM:” field in the SMS message. At 306, the SMS message may be routed to the first device based on the determined routing instructions. In some embodiments, the act of determining routing instructions may include performing a search in resolution partner database 114 to determine if the native network identifier is associated with a subscriber of the first non-native communication server provider. At 308, if it is determined that the native network identifier is associated with a subscriber of the first non-native communication server provider (i.e., the subscriber is registered with the first non-native communication server provider), then the method proceeds to 310. At 310, the SMS message is directed to a forwarding identifier assigned to the first device by the first non-native communication service provider. In some embodiments, the act of directing the SMS message to a forwarding identifier assigned to the first device includes terminating the SMS communication to the first device using a data channel provided by the first non-native communication service provider. If it is determined that the native network identifier is not associated with a subscriber of the first non-native communication server provider (i.e., the subscriber is not registered with the first non-native communication server provider) at 308, then the method proceeds to 312. At 312, the SMS message is directed to the first device via the native telephony service provider associated with the first device.
FIG. 4 is a flow chart of a method for registering a first device, the first device being assigned a native identifier and being associated with a native telephony service provider, with a non-native server provider according to some embodiments of the present invention. Specifically, at 402 a subscriber may register (e.g., opt in) the first device, and the native identifier assigned to the first device, with a first non-native service provider's SMS offering. At 404, a forwarding identifier may be assigned to the first device by first non-native service provide. At 406, the registered native network identifier, assigned forwarding identifier, and other information associated with a subscriber associated with the first device may be stored in a user database (e.g., user information DB 140) maintained by the first non-native communication service provider. At 408, the information stored in the user database may be used to update a resolution database 114 which is used in methods and systems described above. In some embodiments, the resolution database 114 may be updated to include the native network identifiers of subscribers of the first non-native communication server provider using information stored in a user database maintained by the first non-native communication service provider.
The embodiments of the present invention may be embodied as methods, apparatus, electronic devices, and/or computer program products. Accordingly, the embodiments of the present invention may be embodied in hardware and/or in software (including firmware, resident software, micro-code, and the like), which may be generally referred to herein as a “circuit” or “module”.
