Description

SYSTEM AND METHOD FOR MAPPING USER EQUIPMENT IDENTIFIERS

IN A TELECOMMUNICATION NETWORK

FIELD OF THE INVENTION

[0001] The present invention relates to the field of wireless communication systems, more particularly relates to a method and system for mapping user equipment identifiers in a telecommunication network.

BACKGROUND OF THE INVENTION

[0002] In the realm of telecommunications networks, the identification and management of subscriber numbers play a crucial role in ensuring seamless connectivity and effective service provisioning. Two fundamental numbers used for this purpose are a SUPI (Subscription Permanent Identifier) and a MSISDN (Mobile Station International Subscriber Directory Number).

[0003] To monitor and maintain a network performance, telecommunications providers utilize various tools and components, including probes and monitoring systems. Probes are specialized devices or software modules deployed within the network infrastructure to collect data, monitor network traffic, and perform analysis. These probes capture information related to network performance, call quality, data throughput, and other parameters.

[0004] Probing agents mentioned in the discussion are examples of such monitoring systems. These solutions utilizes the probes to collect network data and provide valuable insights into the network's operation and performance. They enable network operators to monitor call quality, detect anomalies, and troubleshoot issues by analyzing the collected data.

[0005] In the context of the invention, the challenge lies in the fact that when one or more customers face network problems, they typically contact customer care with only their mobile numbers (MSISDNs) and are unaware of their associated SUPI numbers. This lack of SUPLMSISDN mapping makes it difficult to troubleshoot network issues accurately. Without this mapping, customer care representatives and network engineers have limited visibility into the specific problems customers are experiencing and struggle to pinpoint the causes. Few technologies offer mapping and real-time monitoring based on Artificial Intelligence/Machine Learning (AI/ML) approach. However, in traditional systems where AI/ML approach has been considered for realtime monitoring, depend on the third party applications/services to provide data for enrichment. The enrichments are achieved offline first, and then the data is made available for the systems, which causes delay in troubleshooting, hinders the proactive and quick remedial actions, and which also involves heavy computing for updating millions of records in one go.

[0006] The invention seeks to address this challenge by providing a solution that enables the mapping of customer numbers (MSISDNs) to their respective SUPI numbers. By establishing this connection, the invention facilitates more efficient troubleshooting and analysis of network issues. It allows customer care representatives and network operators to correlate customer-reported problems with the corresponding SUPI numbers, leading to better identification and resolution of network drops, coverage issues, or other connectivity problems.

[0007] Overall, the invention's main advantages lie in bridging the gap between customer numbers and SUPI or MSISDN numbers, thereby enhancing the ability to troubleshoot network issues accurately and improve customer support. By integrating the mapping capability into systems, the telecommunications providers can leverage the collected data to gain insights, optimize network performance, and deliver a more seamless and reliable communication experience to their subscribers.

[0008] Therefore, there is a need to overcome this challenge and enable efficient troubleshooting. SUMMARY OF THE INVENTION

[0044] The user interface 210 includes a variety of interfaces, for example, interfaces for a Graphical User Interface (GUI), a web user interface, a Command Line Interface (CLI), and the like. The user interface 210 facilitates communication with the system 108. In one embodiment, the user interface 210 provides a communication pathway for one or more components of the system 108. Examples of the one or more components include, but are not limited to, the UE 102, the subscriber data lake 206 and the distributed data lake 208. [0045] In order for the system 108 to map user equipment identifiers in the telecommunication network 106. The processor 202 includes a first probing component 212, a learning module 214, and a second probing component 216 communicably coupled to each other. The processor 202 is communicably coupled to the one or more components of the system 108 such as the subscriber data lake 206, the distributed data lake 208, the User Interface (UI) 210 and the memory 204. In an embodiment, operations and functionalities of the first probing component 212, the learning module 214, the second probing component 216 and the one or more components of the system 108 can be used in combination or interchangeably.

[0046] In one embodiment, the user equipment identifiers include at least one of but not limited to, a Subscription Permanent Identifier (SUPI) number and a Mobile Station International Subscriber Directory Number (MSISDN) number.

[0047] In an embodiment, the first probing component 212 of the processor 202 is configured to receive an operational data from the Network Functions (NFs) 110 particular 5G NFS which includes information related to network performance and call quality associated with the UE 102. In one embodiment, the operational data is raw data received from the Network Functions (NFs) 110. The operational data includes data pertaining to such as at least one of, a bandwidth, latency, and an error rate. The operational data also includes at least one of, the SUPI number and the MSISDN number. The operational data may also be known as Streaming Data Records (SDR) data. The SDR data is the continuous flow of the data from the Network Functions (NFs) 110. In particular, the operational data is associated with the UE 102. The first probing component 212 is configured to identify a Subscription Permanent Identifier (SUPI) number associated with the UE 102 from the received operational data.

[0048] As per one or more embodiments, the operational data is not limited to Fifth Generation (5G) identities. In an alternate embodiment, the operational data includes, but is not limited to Second Generation (2G), Third Generation (3G), Fourth Generation (4G) identities.

[0049] The SUPI is an essential identifier used in 5G networks. The SUPI is a unique identifier assigned to a subscriber and associated with their SIM card or other authentication credentials. The SUPI is used for various purposes, including network access, authentication, and authorization. The SUPI helps to establish a secure and reliable connection between the UE 102 and the telecommunication network 106.

[0050] In one embodiment, the SUPI is equivalent to an International Mobile Subscriber Identity (IMSI). The IMSI is a unique 15-digit number that identifies every subscriber in a Global System for Mobile communication (GSM) and Universal Mobile Telecommunication system (UMTS) network in mobile networks. In particular, the SUPI is usually a string of 15 decimal digits. The first three digits represent the Mobile Country Code (MCC) while the next two or three form the Mobile Network Code (MNC) identifying the network operator. The remaining (nine or ten) digits are known as Mobile Subscriber Identification Number (MSIN) and represent the individual user of that particular operator.

[0051] In one embodiment, each Subscriber Identity Module (SIM) card of the subscribers is issued with the user equipment identifier or a unique identifier. In 2G, 3G, and 4G networks the user equipment identifier is referred to as the IMSI. In 5G networks, the user equipment identifier is referred to as the SUPI.

[0052] The learning module 214 of the processor 202 is configured to receive a Mobile Station International Subscriber Directory Number (MSISDN) number associated with the UE 102 from the subscriber data lake 206. The MSISDN serves as the primary identifier for mobile subscribers and is commonly known as the mobile number. The MSISDN is the phone number associated with the single SIM card and is the number to which subscriber can call or send an SMS message. In particular, the the MSISDN is used for routing calls to the subscriber. The MSISDN uniquely identifies an individual UE 102 within a telecommunication network 106. The MSISDN consists of the country code, the National Destination Code (NDC), and the user/subscriber number. For example, in the MSISDN "+1-555-1234567, " the "+1" represents the country code, the "555" represents the NDC, and the "1234567" represents the subscriber number. The MSISDN is used for routing calls and Short Message Service (SMS) messages to the correct subscriber.

[0053] In one embodiment, the MSISDN is equivalent to a Global Phone Subscriber Identity (GPSI). The GPSI is a unique identifier used to globally identify a subscriber's phone number across different networks. The GPSI is part of the architecture defined in the context of the IP Multimedia Subsystem (IMS) and next-generation networks, such as 5G.

[0054] Upon receiving the MSISDN number associated with the UE 102 from the subscriber data lake 206, the learning module 214 of the processor 202 is further configured to map the identified SUPI number with the MSISDN number. The mapping pertaining to the identified SUPI number with the MSISDN number is performed by the learning module 214 in real time. The real time mapping ensures that the MSISDN number is accurately aligned with the identified SUPI number i.e. the operational data.

[0055] In one embodiment, the learning module 214 is further configured to store details of the mapping between the identified SUPI number and the MSISDN number in the distributed data lake 208. The learning module 214 creates a separate index in the distributed data lake 208 to store this mapping. The learning module 214 updates the details of the mapping by processing the operational data received on a periodic basis. In another embodiment, the learning module 214 updates the details of the mapping when a change occurs in one or more of the MSISDN number and the SUPI number. In alternate embodiment, the details of the mapping is updated in at least one of, the subscriber data lake 206, and the distributed data lake 208. [0056] The second probing component 216 of the processor 202 is configured to allow the user to access the details of the mapping which is in at least one of, the subscriber data lake 206, and the distributed data lake 208 via the User Interface (UI) 210. In an embodiment, the user includes a support team member or a network analyst.

[0057] In one embodiment, the details of the mapping between the SUPI number and the MSISDN number are displayed to the user via the User Interface (UI) 210 to troubleshoot one or more issues raised by the subscriber. In particular, the system 120 ensures the availability of accurate mapping information, empowering the user to effectively analyze and resolve one or more issues raised by the subscriber. In an embodiment, the subscriber includes a customer who encounters a network issue, for an example, poor call quality or data connectivity problems.

[0058] The first probing component 212, the learning module 214, and the second probing component 216, in an exemplary embodiment, are 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 202. 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.

[0059] FIG. 3 illustrates an exemplary block diagram of an architecture that can be implemented in the system of FIG.2, according to one or more embodiments of the present invention. More specifically, FIG. 3 illustrates the system 108 configured for mapping user equipment identifiers in the telecommunication network 106. It is to be noted that the embodiment with respect to FIG. 3 will be explained with respect to the UE 102 for the purpose of description and illustration and should nowhere be construed as limited to the scope of the present disclosure.

[0060] FIG. 3 shows communication between the UE 102, the system 108, the Network Functions (NFs) 110. For the purpose of description of the exemplary embodiment as illustrated in FIG. 3, the UE 102, and the Network Functions (NFs) 110 uses a network protocol connection to communicate with the system 108. In an embodiment, the network protocol connection is the establishment and management of communication between the UE 102, the system 108, and the Network Functions (NFs) 110, over the telecommunication network 106 (as shown in FIG. 1) using a specific protocol or set of protocols. The network protocol connection includes, but not limited to, Session Initiation Protocol (SIP), System Information Block (SIB) protocol, Transmission Control Protocol (TCP), User Datagram Protocol (UDP), File Transfer Protocol (FTP), Hypertext Transfer Protocol (HTTP), Simple Network Management Protocol (SNMP), Internet Control Message Protocol (ICMP), Hypertext Transfer Protocol Secure (HTTPS) and Terminal Network (TEENET).

[0061] In an embodiment, the UE 102 includes a primary processor 302, and a memory 304. In alternate embodiments, the UE 102 may include more than one primary processor 302 as per the requirement of the telecommunication network 106. The primary processor 302, 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.

[0062] In an embodiment, the primary processor 302 is configured to fetch and execute computer-readable instructions stored in the memory 304. The memory 304 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 transmit the MSISDN number associated with the UE 102 to the one or more processors 202. The memory 304 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.

[0063] For example, when the subscriber is facing one or more issues related to at least one of but not limited to, a poor quality of a calling service, then the subscriber connects to the network operator i.e. user in order to complaint the network operator regarding the one or more issues via the UE 102. Further, the network operator receives the operational data associated with the UE 102 via the Network Functions (NFs) 110 Thereafter, the network operator requests the system 108 in order to get the mapped data pertaining to the SUPI number and the MSISDN number so that the network operator can retrieve the mapped data which enables the network operator to troubleshoot one or more issues faced by the subscriber accurately and efficiently.

[0064] As mentioned earlier in FIG.2, the system 108 includes the one or more processors 202, the memory 204, the subscriber data lake 206, and the distributed data lake 208 and the user interface 210. the subscriber data lake 206, and the distributed data lake 208 and the user interface 210 in order to map user equipment identifiers in the telecommunication network are 106 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.

[0065] Further, the processor 202 includes the first probing component 212, the learning module 214, and the second probing component 216. The operations and functions of the first probing component 212, the learning module 214, and the second probing component 216 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 provided

Y1 for the system 108 in the FIG. 2 above, and should not be construed as limiting the scope of the present disclosure.

[0066] FIG. 4 is an exemplary block diagram of an architecture 400 which can be implemented in the system 108 of FIG.2, according to one or more embodiments of the present invention.

[0067] The architecture 400 of the system 108 includes several components and their connections to enable mapping user equipment identifiers in the telecommunication network 106.

[0068] In one implementation, the architecture 400 of the system 108 includes the Network Functions (NFs) 110. The Network Functions (NFs) 110 includes a NF 110a, a NF 110b, and a NF 110c. The NFs HOa-llOc capture and generates Streaming Data Records (SDR) data, specifically the SUPI or the IMSI, associated with the UE 102 of the subscribers. The SDR data is the continuous flow of the data from the NFs 110a- 110c. For example, the SDR includes at least one of, but not limited to, timestamp of request, timestamp of response, etc. The SDR data may also be referred to as the raw data. However, the MSISDN or the GPSI, which are the subscribers' phone numbers, are not sent in the data records by the NFs HOa-llOc.

[0069] In one implementation, the architecture 400 of the system 108 includes the first probing component 212 which receives the SDR data from the NFs HOa-llOc. In one embodiment, the first probing component 212 includes at least one of, but not limited to, a probing agent. The first probing component 212 identifies the SUPI number associated with the UE 102.

[0070] In one implementation, the architecture 400 of the system 108 includes the learning module 214. In one embodiment, the learning module 214 includes an Artificial Intelligence/Machine Learning (AI/ML) module. The learning module 214 receives the MSISDN number associated with the UE 102 from the subscriber data lake 206. The subscriber data lake 206 also known as a Unified Inventory Management (UIM) which serves as a central repository for storing subscriber related information. The subscriber data lake 206 ingests, stores, and allows for processing of large volumes of data in its original form. The subscriber data lake 206 contains data such as the IMSI, the MSISDN, and an Integrated Circuit Card Identifier (ICCID).

[0071] In one embodiment, the learning module 214 maps the SUPI number with the MSISDN number, and ensures that the details of mapping are synched in real time. The learning module 214 store details of the mapping between the SUPI number and the MSISDN number in the distributed data lake 208. The distributed data lake 208 is a storage location where the learning module 214 stores the mapped data pertaining to the MSISDN and SUPI mapping.

[0072] In one implementation, the architecture 400 of the system 108 includes the second probing component 216 which allows the user to access the details of the mapping stored in the distributed data lake 208 allows for analyzing and resolving subscribers one or more issues via the User Interface (UI) 210.

[0073] For example, when the subscriber raises a complaint with the customer care, providing their MSISDN and location details, the customer care utilizes the processor 202 and access the MSISDN-SUPI mapping stored in the distributed data lake 208. This mapping information allows to link the subscribers reported issue with the SDR data, which primarily contains the SUPI. The customer care analyzes the data records related to the mapping and troubleshoot the issue effectively, leading to a faster resolution and improved subscriber experience.

[0074] FIG. 5 is a flow diagram illustrating a method 500 for mapping user equipment identifiers in the telecommunication network 106, according to one or more embodiments of the present disclosure. For the purpose of description, the method 500 is described with the embodiments as illustrated in FIG. 2 and should nowhere be construed as limiting the scope of the present disclosure. [0075] At step 502, the method 500 includes the step of receiving operational data including information related to at least one of network performance and call quality from a 5G Network Function (5g NF), wherein the operational data is associated with a user equipment. In one embodiment, the first probing component 212 of the processor 202 is configured to receive operational data including information related to at least one of network performance and call quality from the network functions 110. In particular, the operational data is associated with the UE 102. For example, the the first probing component 212 receives the operational data from the NFs 110 without the MSISDN.

[0076] At step 504, the method 500 includes the step of identifying a Subscription Permanent Identifier (SUPI) number associated with the UE 102 from the operational data. In an embodiment, the first probing component 212 of the processor 202 is configured to identify the SUPI number associated with the UE 102 from the received operational data.

[0077] At step 506, the method 500 includes the step of receiving a Mobile Station International Subscriber Directory Number (MSISDN) number associated with the UE 102 from the subscriber data lake 206. In an embodiment, the learning module 214 of the processor 202 is configured to receive MSISDN number associated with the UE 102 from the subscriber data lake 206. For example, the the first probing component 212 receives the SUPI from the NFs 110 based on which the learning module 214 fetches the MSISDN number associated with the UE 102 from the subscriber data lake 206.

[0078] At step 508, the method 500 includes the step of mapping the SUPI number with the MSISDN number. In an embodiment, the learning module 214 of the processor 202 is configured to map the identified SUPI number with the MSISDN number in real time. The real-time mapping process ensures that the is SUPI aligned with the MSISDN. In particular, by performing mapping operation in real time, the learning module 214 enables immediate analysis, facilitating prompt and precise insights into network performance of the subscriber. For example, the one-to-one mapping of the MSISDN number is done with the SUPI number of the subscriber based on at least one of, a common field between the MSISDN number and the SUPI number. In other words, the MSISDN number of the subscriber A is mapped with the SUPI number of the subscriber A and vice versa. Herin the common field may be a subscriber profile which may include the details of subscriber such as name, date of birth, etc.

[0079] At step 510, the method 500 includes the step of storing details of the mapping between the SUPI number and the MSISDN number in a distributed data lake 208. In an embodiment, the learning module 214 of the processor 202 is configured to store details of the mapping in the distributed data lake 208. For example, the details of the mapping include at least one of, but not limited to, the common field based on which the mapping is done, and the mapping of the MSISDN number with SUPI number for each subscriber. The learning module 214 creates a separate index in the distributed data lake 208 to store this mapping. Further, the learning module 214 continuously updates the details of the mapping by processing the operational data received on the periodic basis when a change occurs in at least one of the MSISDN number and the SUPI number. For example, when the at least one of the MSISDN number and the SUPI number is changes, the mapping is updated accordingly.

[0080] Thereafter, whenever the user requires the details between the mapping of the identified SUPI number and the MSISDN number, the user fetches the details of the mapping from the distributed data lake 208 via the second probing component 216. The fetched details are displayed to the user via the User Interface (UI) 210 which facilitates in troubleshooting the one or more issues raised by the subscriber.

[0081] The present invention further discloses a non-transitory computer-readable medium having stored thereon computer-readable instructions. The computer- readable instructions are executed by the processor 202. The processor 202 is configured to receive operational data including information related to at least one of network performance and call quality from a 5G Network Function (5g NF) 110, wherein the operational data is associated with a user equipment 102. The processor 202 is configured to identify a Subscription Permanent Identifier (SUPI) number associated with the user equipment 102 from the operational data. The processor 202 is configured to receive a Mobile Station International Subscriber Directory Number (MSISDN) number associated with the user equipment 102 from a subscriber data lake 206. The processor 202 is configured to map the SUPI number with the MSISDN number. The processor 202 is configured to store details of the mapping between the SUPI number and the MSISDN number in a distributed data lake 208.
