THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE NATURE OF THIS INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED.

FIELD OF THE INVENTION
[0001] The present invention relates to messaging between networks, more particularly relates to method and system for routing one or more messages from a home network to a foreign network.
BACKGROUND OF THE INVENTION
[0002] Short code messaging has become an integral part of modern communication, allowing users to send concise, standardized messages using abbreviated numeric or alphanumeric codes for various purposes, such as voting, subscribing to services, or receiving information updates. However, the existing systems for sending short code messages to External Short Messaging Entity (ESMEs) are often limited to specific networks or service providers. This creates fragmentation and inconvenience for users and service providers, as they must rely on different mechanisms to send messages to ESMEs across diverse networks.
[0003] Presently, there are several standardized protocols, such as the Short Message Peer-to-Peer (SMPP) protocol, that facilitate the exchange of short messages between Short Message Service Centers (SMSCs) and ESMEs. Short codes are numeric addresses, that are typically 3 to 6 digits long used by wireless carriers to enable access to message based value-added applications and services. A single ESME may have multiple simultaneous short codes for different services for example, “cricket match scores” and “voting”. Typically, short codes of the Short Message Service (SMS) application are hosted by a home network. The home network may forward the SMS message request to the appropriate ESME. The ESME may respond with an appropriate SMS message response containing, for example, cricket score or other information.
[0004] In the case of Peer to Application (P2A) messages, when short codes of the SMS application are hosted by another network other than home network, SMS messages cannot be directly routed from a user's home network. As a result, home network users cannot access or utilize the services provided by other network applications. This limitation occurs due to the inability to establish a direct connection between the home network and the hosting operator, preventing seamless interaction between the user and the application.
[0005] Hence, there exists a need for an improved method and system that enables routing of short code messages to ESMEs hosted in other network for accessing services and applications of other operators. The present invention aims to overcome the abovesaid drawbacks and provide a seamless, efficient interaction of users with services and applications of other network.

The system 108 is configured for routing the one or more messages from the home network 106 to the foreign network 110. As per one or more embodiments, the system 108 is adapted to be embedded within the server 104 or embedded as an individual entity.
[0033] Operational and construction features of the system 108 will be explained in detail with respect to the following figures.
[0034] FIG. 2 is an exemplary block diagram of the system 108 for routing one or more messages from the home network 106 (as shown in FIG. 1) to the foreign network 110 (as shown in FIG. 1), according to one or more embodiments of the present invention.
[0035] As per the illustrated embodiment, the system 108 includes one or more processors 202, a memory 204, a user interface 206, and a database 208. For the purpose of description and explanation, the description will be explained with respect to one processor 202 and should nowhere be construed as limiting the scope of the present disclosure. In alternate embodiments, the system 108 may include more than one processors 202 as per the requirement of the home network 106 and the foreign network 110. The one or more processors 202, hereinafter referred to as the processor 202 may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, state machines, logic circuitries, single board computers, and/or any devices that manipulate signals based on operational instructions.
[0036] As per the illustrated embodiment, the processor 202 is configured to fetch and execute computer-readable instructions stored in the memory 204. The memory 204 may be configured to store one or more computer-readable instructions or routines in a non-transitory computer-readable storage medium, which may be fetched and executed to create or share data packets over a network service. The memory 204 may include any non-transitory storage device including, for example, volatile memory such as RAM, or non-volatile memory such as disk memory, EPROMs, FLASH memory, unalterable memory, and the like.
[0037] In an embodiment, the user interface 206 includes a variety of interfaces, for example, interfaces for a graphical user interface, a web user interface, a Command Line Interface (CLI), and the like. The user interface 206 facilitates communication of the system 108. In one embodiment, the user interface 206 provides a communication pathway for one or more components of the system 108. Examples of such components include, but are not limited to, the UE 102, (as shown in FIG. 1) and the database 208.
[0038] The database 208 is one of, but not limited to, a centralized database, a cloud-based database, a commercial database, an open-source database, a distributed database, an end-user database, a graphical database, a No-Structured Query Language (NoSQL) database, an object-oriented database, a personal database, an in-memory database, a document-based database, a time series database, a wide column database, a key value database, a search database, a cache databases, and so forth. The foregoing examples of database 208 types are non-limiting and may not be mutually exclusive e.g., a database can be both commercial and cloud-based, or both relational and open-source, etc.
[0039] In order for the system 108 to route the one or more messages from the home network 106 to the foreign network 110, the processor 202 includes one or more modules. In one embodiment, the one or more modules includes, but not limited to, a receiving unit 212, an identification unit 214, a conversion unit 216 and a routing unit 218 communicably coupled to each other for routing the one or more messages from the home network 106 to the foreign network 110.
[0040] The receiving unit 212, the identification unit 214, the conversion unit 216 and the routing unit 218 in an embodiment, may be implemented as a combination of hardware and programming (for example, programmable instructions) to implement one or more functionalities of the processor 202. In the examples described herein, such combinations of hardware and programming may be implemented in several different ways. For example, the programming for the processor 202 may be processor-executable instructions stored on a non-transitory machine-readable storage medium and the hardware for the processor may comprise a processing resource (for example, one or more processors), to execute such instructions. In the present examples, the memory 204 may store instructions that, when executed by the processing resource, implement the processor. In such examples, the system 108 may comprise the memory 204 storing the instructions and the processing resource to execute the instructions, or the memory 204 may be separate but accessible to the system 108 and the processing resource. In other examples, the processor 202 may be implemented by electronic circuitry.
[0041] In one embodiment, the receiving unit 212 is configured to receive a short code to long code map from an application on the server 104 in the foreign network 110. The short code is a specialized five to six-digit phone number used to address messages in the Multimedia Messaging System (MMS) and short message service (SMS) systems of mobile network operators. For example, the short code five to six-digit phone number may look like “620039”, “620045”. The long code is a standard phone number used to send and receive voice calls and SMS messages. The application refers to software that is installed and run on the server 104. The application includes, but is not limited to, web server, database server, file server, email server, Content Management System (CMS), media streaming server, game server, remote access and VPN server, IoT server, virtualization server.
[0042] Further, the receiving unit 212 is also configured to receive the one or more messages from the short code associated with the UE 102 registered in the home network 106. Upon receiving the one or more messages from the UE 102, the identification unit 214 is configured to identify the long code for the corresponding short code upon receipt of the one or more messages from the UE 102 based on the short code to the long code map. Accordingly, for identifying the long code for the corresponding short code, the identification unit 214 is configured to parse the short code to long code map. The short code to long code map is parsed upon receipt of the one or more messages to identify the long code for the corresponding short code.
[0043] Upon identifying the long code for the corresponding short code, the conversion unit 216 is configured to convert the short code to the identified long code. More specifically the short code is converted to the long code. Upon conversion, the long code is used for further message flow between the home network 106 and the foreign network 110.
[0044] Accordingly, the routing unit 218 is configured to route the one or more messages to the application on the server 104 in the foreign network 110. In one embodiment, if the identification unit 214 fails to identify the long code for the corresponding short code, the routing unit 218 is configured to route the one or more messages to content providers. The content providers refer to an entity which supplies content in the form of streaming media or non-real-time (NRT) files to be delivered to UE 102 over the 3GPP network, via Multimedia Broadcast/Multicast Service (MBMS) bearer and/or unicast bearer services. The content provider may reside either inside or outside the operator's network.
[0045] In one embodiment, the system 108 determines whether mapping of long code exists against the short code. Further CRUD operations at the database 208 for retrieving the mapping and may be supported both at runtime and startup of the operations. CRUD is the acronym for Create, Read, Update and Delete. The four functions Create, Read, Update and Delete describe the four essential operations for implementing a persistent storage application. In an embodiment, several applications are transmitted to IPSMGW with their short code to long code mapping, and IPSMGW stores the short code to long code map at the database 208 by using CRUD operations.
[0046] Therefore, the user using the UE 102 in the home network 106 can send the one or more messages to the server 104 in the foreign network 110. More specifically, Person-to-Application (P2A) Short Message Service (SMS) can be sent by user through short code which is quite easier to remember to use even though the actual recipient of the SMS is resided in the foreign network. Further, the recipient application will not have to reside in every operator’s network to use the short code.
[0047] FIG. 3 describes a preferred embodiment of the system 108 of FIG. 2, according to various embodiments of the present invention. It is to be noted that the embodiment with respect to FIG. 3 will be explained with respect to the first UE 102a and the system 108 for the purpose of description and illustration and should nowhere be construed as limited to the scope of the present disclosure.
[0048] As mentioned earlier in FIG. 1, each of the first UE 102a the second UE 102b, and the third UE 102c may include an external storage device, a bus, a main memory, a read-only memory, a mass storage device, communication port(s), and a processor. The exemplary embodiment as illustrated in FIG. 3 will be explained with respect to the first UE 102a without deviating from the scope of the present disclosure and the limiting the scope of the present disclosure.

[0049] The one or more primary processors 302 are coupled with a memory unit 304 storing instructions which are executed by the one or more primary processors 302. Execution of the stored instructions by the one or more primary processors 302 enables the first UE 102a to transmit one or more messages to the server 104 in the foreign network 110.
[0050] As mentioned earlier in FIG. 2, the one or more processors 202 of the system 108 is configured for routing the one or more messages from the home network 106 to the foreign network 110. As per the illustrated embodiment, the system 108 includes the one or more processors 202, the memory 204, the user interface 206, and the database 208. The operations and functions of the one or more processors 202, the memory 204, the user interface 206, and the database 208 are already explained in FIG. 2. For the sake of brevity, a similar description related to the working and operation of the system 108 as illustrated in FIG. 2 has been omitted to avoid repetition.
[0051] Further, the processor 202 includes the receiving unit 212, the identification unit 214, the conversion unit 216 and the routing unit 218. The operations and functions of the receiving unit 212, the identification unit 214, the conversion unit 216 and the routing unit 218 are already explained in FIG. 2. Hence, for the sake of brevity, a similar description related to the working and operation of the system 108 as illustrated in FIG. 2 has been omitted to avoid repetition. The limited description provided for the system 108 in FIG. 3, should be read with the description as provided for the system 108 in the FIG. 2 above, and should not be construed as limiting the scope of the present disclosure.
[0052] FIG. 4 is an exemplary block diagram of an architecture 400 of the system 108 of the FIG. 2, according to one or more embodiments of the present invention.
[0053] The architecture 400 includes an IP Short Message Gateway (IP-SM-GW) 402, a Home Subscriber Service (HSS) 404, a Short Message Service Gateway Mobile Switching Center / Short Message Service Interworking Mobile Switching Center (SMS-GMSC / SMS-IWMSC) 406, a Service Centre (SC) 408, a Short Message Entity (SME) 410, a Serving – Call Session Control Function (S-CSCF) 412, a Proxy – Call Session Control Function (P-CSCF) 414, a Charging Gateway Function / Charging Data Function (CGF/CDF) 416, an Online Charging System (OCS) 418, and the UE 102.
[0054] As per the illustrated embodiment, the IP-SM-GW 402 shall provide the protocol interworking for delivery of the short message between an IP-based UE and a Short Message Service - Service Center (SMS-SC). The message is routed to the SMS-SC for delivery to the SMS-based user or the message is received from the SMS-SC of an SMS-based UE for delivery to the IP-based UE.
[0055] The E/Gd/Gdd/SGd interface allows the IP-SM-GW 402 to connect to the SMS-GMSC 406, appearing to the SMS-GMSC 406 as a Mobile switching center (MSC), Serving GPRS Support Node (SGSN) or Mobility Management Entity (MME).
[0056] The SMS-GMSC 406 function of the MSC capable of receiving a short message from the SC 408, interrogating a Home Location Register (HLR) for routing information and SMS info, and delivering the short message to the Visited Mobile Switching Centre (VMSC) or the SGSN of the recipient Mobile Station (MS). The MSC exchange performs switching functions for mobile stations located in a geographical area designated as the MSC area.
[0057] The SMS-IWMSC 406 acts as an interface between the IP-SM-GW 402 and a Short Message Service Centre (SMSC) to help short messages to be transferred from Mobile Stations to the SC 408.
[0058] The SC 408 responsible for the relaying and store-and-forwarding of a short message between a Small and Medium Enterprises (SME) 410 and the MS. The SME 410 is an entity which may send or receive short messages.
[0059] The HSS 404 functions as the central database for subscriber-related information and plays a key role in managing user authentication, authorization, and mobility.
[0060] The SMS-GMSC / SMS-IWMSC 406 is connected to the HSS 404 via the C/S6c interface. The C/S6c interface allows the SMS-GMSC 406, using Mobile Application Part (MAP) or a Diameter based protocol, to obtain the address of the IP-Message-GW.
[0061] The HSS 404 is connected to IP-SM-GW 402 through Sh and J/S6c interface. The Sh interface connects the HSS 404 to application servers within an IP Multimedia Subsystem (IMS) network. The J interface is used for communication between the Home Location Register (HLR) and the Authentication Centre (AuC). The J interface is primarily responsible for managing authentication data and generating authentication vectors. The S6c interface facilitates communication between the Mobility Management Entity (MME) and the HSS 404. The S6c interface is used for subscription management, authentication, and mobility-related functions.
[0062] The IP-SM-GW 402 is connected to S-CSCF 412 through ISC interface. The ISC interface allows the IP-SM-GW to forward the receiving message to a Session Initiation Protocol (SIP) based the UE 102 via IMS core
[0063] The S-CSCF 412 is the primary node in the IMS responsible for session control. Subscribers will be allocated a S-CSCF 412 for the duration of their IMS registration in order to facilitate routing of SIP messages as part of service establishment procedures.
[0064] The S-CSCF 412 and the P-CSCF 414 are connected through Mw interface. The Mw interface enables communication between the different CSCF nodes within the IMS network. The Mw interface is used for the SIP signaling, which is essential for establishing, modifying, and terminating multimedia sessions.
[0065] The P-CSCF 414 is a SIP proxy that is the first point of contact for the IMS terminal. The P-CSCF 414 can be located either in the foreign network 110 (in full IMS networks) or in the home network 106 (when the visited network is not IMS compliant yet).
[0066] The P-CSCF 414 and the UE 102 are connected through Gm interface. The Gm interface plays a significant role in managing SIP signaling for initiating, maintaining, and terminating multimedia communication sessions.
[0067] The IMS core network consists of several key interfaces that facilitate communication between various functional entities, enabling multimedia services over IP networks. The key interfaces include, but not limited to, Mw interface, Gm interface, Rx interface, ISC interface.
[0068] The CGF 416 acts as a gateway between the 3GPP network and a Billing Domain (BD). It uses the Bx reference point for the transfer of Charging Data Record (CDR) files to the BD. The CDF 416 receives charging events from a Charging Trigger Function (CTF) via the Rf reference point. The CDF then uses the information contained in the charging events to construct CDRs.
[0069] The CGF/CDF 416 is connected to IP-SM-GW 402 through RF interface. The Rf interface connects various network elements to the CDF 416, enabling the collection and forwarding of charging data for post-processing and billing.
[0070] The OCS 418 is responsible for real-time charging and billing for various services. The OCS 418 is connected to IP-SM-GW 402 through Ro interface. The Ro interface is used for IMS and other service platforms. The Ro interface supports online charging for voice, video, and multimedia services provided over IMS.
