TECHNICAL FIELD
[0002] The embodiments of the present disclosure generally relate to a field of wireless networks, and specifically to a method and an apparatus for downloading a functional profile on an embedded universal integrated circuit card (eUICC) of a Non Display (ND) fixed device.

BACKGROUND
[0003] The following description of the related art is intended to provide background information pertaining to the field of the disclosure. This section may include certain aspects of the art that may be related to various features of the present disclosure. However, it should be appreciated that this section is used only to enhance the understanding of the reader with respect to the present disclosure, and not as admissions of the prior art
[0004] Prevalent mechanisms to onboard an Embedded Universal Integrated Circuit Card (eUICC) capable non display (ND) fixed device have specific requirements and limitations. For instance, the ND device typically rely on a machine 2 machine (M2M) eUICC technology due to absence of a user interface, such as local profile assistants - user interface (LPA-UI), necessitating a preloaded or pre-activated bootstrap profile to download a functional profile. However, in case if the bootstrap profile is deactivated then downloading a new functional profile is impossible, necessitating an embedded-subscriber identity module (eSIM) change that requires the ND fixed device refurbishment. Further, installation engineers are required to possess a dedicated RF measurement instrument to gauge available network connectivity, signal strength, and installation site conditions before commencing installation of the ND fixed device at a customer premises.
[0005] In addition, due to lack of a display for the ND fixed device, downloading the functional profile from a companion application available on a connected wireless device may pose certain limitations. Further, even after successful installation of the ND fixed device at the customer premises, there may be a possibility of having a poor network coverage along with cell congestion if multiple ND fixed devices are connected to a single cell.
[0006] There is, therefore, a need in the art to provide an improved method and an apparatus to address issues related to installation, priority cell allocation, and downloading of the functional profile on the eUICC of the ND fixed device.

[0052] Various embodiments of the present disclosure will be explained in detail with reference to FIGs. 1-8.
[0053] FIG. 1 illustrates an exemplary network architecture of a system 100, in accordance with an embodiment of the present disclosure.
[0054] As illustrated in FIG. 1, the system 100 may include a wireless terminal 102 and the ND fixed device 104. The wireless terminal 102 may be interchangeably referred to as a primary device or a User Equipment (UE). The wireless terminal 102 may include, but not be limited to, smart phones, tablets, or other devices for monitoring or interacting with an associated field engineer and/or an entity, or any combination thereof. A person of ordinary skill in the art will appreciate that the primary device 102, or the wireless terminal 102 may include, but is not limited to, intelligent, multi-sensing, network-connected devices, that can integrate seamlessly with each other and/or with a central server or a cloud-computing system or any other device that is network-connected.
[0055] The ND fixed device 104 may be interchangeably referred to as a companion device 104. The ND fixed device 104 may include, but not be limited to, an Outdoor Customer Premises Equipment (OD-CPE), a Long Term Evolution (LTE) device, a set top box, wireless modem, and the like.
[0056] A person of ordinary skill in the art will appreciate that the wireless terminal 102 and the ND fixed device 104 may not be restricted to the mentioned devices and various other devices may be used.
[0057] In an exemplary embodiment, the ND fixed device 104 may communicate with the wireless terminal 102 through a network 106. The network 106 may include, by way of example but not limitation, one or more of: a wireless network, a wired network, an internet, an intranet, a public network, a private network, a packet-switched network, a circuit-switched network, a cellular network, a satellite network, a fiber optic network, some combination thereof.
[0058] In an exemplary embodiment, the ND fixed device 104 may establish a connection with a profile maintaining server 108 using, for example, the SM-DP+ address. The connection may be facilitated via the wireless terminal 102. The SM-DP+ address is a unique address that identifies the profile maintaining server 108, for example, a SM-DP server, and allows to download and manage an embedded subscriber identity module (eSIM). The SM-DP+ address may bind protected profile packages to a respective Embedded Identity Document (EID) and securely download these bound profile packages to a local profile assistant (LPA) of a respective eUICC. Further, the SM-DP+ may host a profile of a mobile network operator (MNO) and may download the functional profile on the eUICC. In addition, an integral hub of an eSIM architecture, known as a Subscription Manager Data Preparation (SMDS), may be included that enables secure provisioning and sophisticated management of operator profiles, and may also be utilized to trigger the functional profile downloads. The functional profile may be an eSIM profile.
[0059] In an embodiment, the wireless terminal 102 may be connected with the ND fixed device 104 over a Bluetooth connection. A Bluetooth tethering may be performed by the wireless terminal 102 to provide data connectivity to the ND fixed device 104. In an embodiment, the wireless terminal 102 may be equipped with a companion application 110 to manage services of the ND fixed device 104, such as but limited to providing data connectivity, triggering remote SIM provisioning (RSP) operations, and the like. The companion application 110 may act as an easy to use interface as per business requirements and may provide Remote SIM Provisioning (RSP) management capabilities for the ND fixed device 104.
[0060] In an embodiment, the ND fixed device 104 may rely on capabilities of the wireless terminal 102 for purposes of the RSP. The ND fixed device 104, for example, the OD-CPE may have a consumer eUICC, and may rely on the wireless terminal 102 to manage connections that may be essentially required to install and manage the functional profiles.
[0061] In an embodiment, the ND fixed device 104 may be equipped with an LPA software development kit (SDK). The SDK may be a set of platform-specific building tools used by developers having components such as but not limited to debuggers, compilers, and libraries that may be used to create a code that runs on, for example, a specific platform, an operating system, or a programming language. A local profile assistant software development kit (LPA SDK) present on the ND fixed device 104 is Global System for Mobile Communications Association (GSMA) SGP.22 compliant.
[0062] In an embodiment, the ND fixed device 104 may be equipped with an LPA manager/LPA proxy. The LPA manager/LPA proxy is a customized application that may be used to establish a Bluetooth connection with the companion application 110 present on the wireless terminal 102. The LPA manager/LPA proxy may receive Representational State Transfer Application Programming Interface (REST API) calls from the companion application 110 which in turn may call relevant APIs of the LPA SDK. In an exemplary embodiment, certain APIs may be implemented as part of the LPA manager, for example, APIs related to login, getting serving cell ID, getting cell information, for example, Signal Interference Noise Ratio (SINR)/Reference Signals Received Power (RSRP)/Reference Signals Received Quality (RSRQ)), and the like.
[0063] In an embodiment, the ND fixed device 104 may send various attributes associated with a selected priority cell (interchangeably referred to as a PLMN priority cell) of available one or more priority cells to the companion application 110 of the wireless terminal 102. The attributes may be, for example, cell ID, throughput, and signal strength associated with the selected PLMN priority cell.
[0064] In an embodiment, the ND fixed device 104 may receive one or more instructions from the companion application 110 for re-orientation of the ND fixed device 104 during installation. The re-orientation or re-alignment of the ND fixed device 104 may be performed to camp the ND fixed device 104 to the selected PLMN priority cell, and to thus improve signal reception, network coverage, and network throughput of the installed ND fixed device 104.
[0065] In an embodiment, the profile maintaining server 108 may receive, via a secure connection, a request from the ND fixed device 104 to download the functional profile onto the eUICC of the ND fixed device 104. This request may be initiated by the companion application 110, subsequent to a successful installation of the ND fixed device 104. Based on the request, the downloading of the functional profile on the ND fixed device 104 may be initiated via the secure connection, for example, a Hypertext Transfer Protocol Secure (HTTPS) connection. In an embodiment, the functional profile may be dynamically linked at the profile maintaining server 108 to the EID associated with the ND fixed device 104.
[0066] In an embodiment, a pre-provisioned eUICC profile may be dynamically downloaded at the ND fixed device 104 from the companion application 110. The dynamic downloading may be performed when the ND fixed device 104 is reoriented/realigned to achieve an optimized orientation.
[0067] Although FIG. 1 shows exemplary components of the network architecture, in other embodiments, the network architecture may include fewer components, different components, differently arranged components, or additional functional components than depicted in FIG. 1. Additionally, or alternatively, one or more components of the network architecture may perform functions described as being performed by one or more other components of the network architecture.
[0068] FIG. 2 illustrates an exemplary block diagram 200 of the ND fixed device 104, in accordance with an embodiment of the present disclosure. In an embodiment, and as shown in FIG. 2, the ND fixed device 104, may include one or more processors 202. The one or more processors 202 may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, logic circuitries, and/or any devices that manipulate data based on operational instructions. Among other capabilities, the one or more processors 202 may be configured to fetch and execute computer-readable instructions stored in a memory 204 of the ND fixed device 104. The memory 204 may store one or more computer-readable instructions or routines, which may be fetched and executed to create or share the data units over a network service. The memory 204 may comprise any non-transitory storage device including, for example, volatile memory such as Random-Access Memory (RAM), or non-volatile memory such as an Erasable Programmable Read-Only Memory (EPROM), a flash memory, and the like. One or more components of the ND fixed device 104 include, but are not limited to, processing engine(s) 206, a transceiver 218, and a database 216.
[0069] In an embodiment, the processing engine(s) 206 may be implemented as a combination of hardware and programming (for example, programmable instructions) to implement one or more functionalities of the processing engine(s) 206. In examples, described herein, such combinations of hardware and hardware and programming may be implemented in several different ways. For example, the programming for the processing engine(s) 206 may be processor-executable instructions stored on a non-transitory machine-readable storage medium and the hardware for the one or more processors 202 may comprise a processing resource (for example, one or more processors), to execute such instructions. In the present examples, the machine-readable storage medium may store instructions that, when executed by the processing resource, implement the processing engine(s) 206. In such examples, the ND fixed device 104 may comprise the machine-readable storage medium storing the instructions and the processing resource to execute the instructions, or the machine-readable storage medium may be separate but accessible to the ND fixed device 104 and the processing resource. In other examples, the processing engine(s) 206 may be implemented by an electronic circuitry.
[0070] In an embodiment, the database 216 may comprise data that may be either stored or generated as a result of functionalities implemented by any of the components of the processors 202 or the processing engine(s) 206 or the ND fixed device 104.
[0071] In an exemplary embodiment, the processing engine(s) 206 may include one or more engines selected from any of a transmission engine 208, a receiving engine 210, a sending engine 212 and other units/engines 214. The other units/engines 214 may include, but are not limited to, a checking engine, a downloading engine, and the like.
[0072] In an embodiment, the one or more processors 202 may, via the transmission engine 208, transmit one or more attributes of the selected PLMN priority cell of the available one or more PLMN priority cells to a connected wireless terminal 102. The ND fixed device 104 and the wireless terminal 102 may be connected over any of a wired or a wireless network connection.
[0073] In an embodiment, in response to a confirmation of the one or more attributes of the selected PLMN priority cell being accepted, the one or more processors 202 may, via the receiving engine 210, receive a re-orientation instruction from the wireless terminal 102, for re-orienting the ND fixed device 104 to camp onto the selected PLMN priority cell. The one or more attributes of the selected PLMN priority cell of the available one or more PLMN priority cells may be at least one of a cell ID, throughout, and signal strength. The one or more attributes may be accepted when the selected PLMN priority cell has a predetermined throughput, and signal strength.
[0074] In an embodiment, a backend information technology (IT) system of the MNO may provide priority information regarding the available one or more PLMN priority cells, categorized with respect to Priority 1 (P1), P2, and P3 to the companion application 110 of the wireless terminal 102. This information may be based on location of an installation site and may be shared with the service engineer during the installation of the ND fixed device 104. In an embodiment, a Priority Cell (NCI) concept may be used to ascertain whether the selected priority cell is suitable for deploying the ND fixed device 104. Moreover, the ND fixed device 104 may transmit details of the selected priority cell, such as its cellID and signal strength, to the companion application 110 without necessitating download and activation of the eUICC profile. Further, when the ND fixed device may camp on a cell based on the PLMN of an enabled profile, the ND fixed device may provide similar details such as the NCI of a campaigned cell and signal strength after downloading and enabling of the functional profile.
[0075] In addition, the service engineer may be guided by the companion application 110 for re-orientation/re-alignment of the ND fixed device 104 to achieve an optimum signal of the selected priority cell. Installation journey of the ND fixed device 104 may not be considered complete till the ND fixed device 104 does not report a predetermined level of the SINR on the selected priority cell. This process may allow the ND fixed device 104 to camp on the selected priority cell, thus avoiding a possibility of making one particular cell congested as multiple ND fixed devices may be attached to the selected priority Cell.
[0076] In an embodiment, the one or more processors 202 may, via the receiving engine 210, receive an instruction to initiate a request for downloading the functional profile from a profile maintaining server 108. On completion of the downloading of the functional profile on the ND fixed device 104, the functional profile may be enabled at the ND fixed device 104. In an embodiment, a Uniform Resource Locator (URL) corresponding to the profile maintaining server 108 may be pre-configured inside the eUICC of the ND fixed device 104.
[0077] In an embodiment, the one or more processors 202 may, via the sending engine 212, send an error free code upon a successful downloading and enabling of the functional profile at the ND fixed device 104. In an embodiment, the sending engine 212, may send an error-code upon an unsuccessful downloading and enabling of the functional profile at the ND fixed device 104.

In such examples, the wireless terminal 102 may comprise the machine-readable storage medium storing the instructions and the processing resource to execute the instructions, or the machine-readable storage medium may be separate but accessible to the wireless terminal 102 and the processing resource. In other examples, the processing engine(s) 306 may be implemented by an electronic circuitry.
[0082] In an embodiment, the database 318 may comprise data that may be either stored or generated as a result of functionalities implemented by any of the components of the processors 302 or the processing engine(s) 306 or the wireless terminal 102.

The other units/engines 314 may include, but are not limited to a downloading engine, and the like.
[0084] In an embodiment, the one or more processors 302 may, via the receiving engine 308, receive one or more attributes of the selected PLMN priority cell of the available one or more PLMN priority cells.
[0085] In an embodiment, the one or more processors 302 may, via the sending engine 310, send a re-orientation instruction to the ND fixed device 104 for re-orienting and camping onto the selected PLMN priority cell. This may be done in response to the confirmation of the one or more attributes of the selected PLMN priority cell being accepted. The one or more attributes may be accepted when the selected PLMN priority cell has a predetermined throughput, and signal strength.
[0086] In an embodiment, the one or more processors 206 may, via the transmission engine 312, transmit an instruction to initiate a request for downloading the functional profile from the profile maintaining server 108. On completion of the downloading of the functional profile on the ND fixed device 104, the functional profile may be enabled at the ND fixed device 104.
[0087] In an embodiment, the one or more processors 302 may, via the receiving engine 308, receive a positive result upon a successful downloading and enabling of the functional profile at the ND fixed device 104.
[0088] In an embodiment, the one or more processors 302 may be further configured to install at least one of the companion application 110 or a web graphical user interface (GUI) on the wireless terminal 102.

[0089] In an embodiment, the one or more processors 302 may be further configured to download the functional profile from the profile maintaining server 108, that is connected over a secure connection to the ND fixed device 104 via the wireless terminal 102.
[0090] Although FIG. 3 shows exemplary components of the wireless terminal 102, in other embodiments, the wireless terminal 102, may include fewer components, different components, differently arranged components, or additional functional components than depicted in FIG. 3. Additionally, or alternatively, one or more components of the wireless terminal 102 may perform functions described as being performed by one or more other components of the wireless terminal 102.
[0091] FIG. 4 illustrates a sequence flow 400 for installation, logging into and onboarding of the ND fixed device 104, in accordance with an embodiment of the present disclosure.
[0092] As illustrated in FIG. 4, in step 1, both the wireless terminal 102 and the ND fixed device 104 are powered ‘ON’. It is to be noted that upon powering ‘ON’ of the ND fixed device 104, there is no functional profile available at the eUICC of the ND fixed device 104. During step 2, a Bluetooth pairing occurs between both the wireless terminal 102 and the ND fixed device 104. In step 3, a personal area network (PAN) connection is established, and the wireless terminal 102 performs a login operation to access the ND fixed device 104. Given that the ND fixed device 104 is tethered to a specific MNO, it may be pre-configured with a MNO PLMN, at step 4.
[0093] At step 5, the ND fixed device 104 may retrieve PLMN information and may attempt to detect a strongest cell within its vicinity. The ND fixed device 104 may, at step 6, collect comprehensive details from the strongest cell and then transmit this information to the companion application 110 of the wireless terminal 102. At step 7, the companion application 110 may calculate and determine an estimated signal strength by considering throughput of the strongest cell from amongst other available cells.
[0094] At step 8, the companion application 110 may determine whether the strongest cell is appropriate to be used for the installation of the ND fixed device 104, else at step 9, a service engineer is advised to adjust placement of the ND fixed device 104 for improved signal reception. During the installation, the companion application 110 may continuously display quality details of the strongest cell on the display of the wireless terminal 102 while the service engineer makes adjustments or re-aligns the ND fixed device 104.
[0095] Upon detecting an optimal position for the strongest cell in a Frequency Range (FR1) network and a best beam in a FR2 network and subsequent generations, the service engineer may conduct a rapid throughput test using the companion application 110 to determine a theoretical or an anticipated throughput value of the strongest cell. Considering all possible permutations and combinations, the service engineer may then install the ND fixed device 104 at a best available location while keeping into consideration commercial/enterprise use cases. On the successful installation of the ND fixed device 104, the wireless terminal 102 may initiate downloading of the functional profile at the ND fixed device 104, at step 10.
[0096] As may be appreciated, using the disclosed mechanism, the ND fixed device 104 may not be required to attach itself to the network to know the best location and orientation required for the installation. The mechanism may be executed before installation of the ND fixed device 104, thus reducing an overall installation time and activation of the functional profile associated with the EID following service level agreements.
[0097] Once a best network coverage/throughput and location for the ND fixed device 104 has been finalized using a network information, the service engineer may proceed to download a pre-provisioned eUICC profile which may be allocated at the profile maintaining server 108, for example, the SM-DP+, to the ND fixed Device EID. This profile allocation/binding to the EID may happen dynamically instead of a static binding operation. In the dynamic EID binding approach, there is no need for providing an input activation code or scanning a QR code by the service engineer. To minimize the service engineer’s involvement and make the installation process smooth, the proposed mechanism uses global system for mobile communications association (GSMA) API - profile download by default SM-DP+ address. Next, at step 11, the functional profile may be downloaded and enabled at the ND fixed device 104, for example, the OD-CPE, and this marks the completion of the sequence flow.
[0098] FIG. 5 illustrates an exemplary interface 500 representing a use case for onboarding of the ND fixed device 104, in accordance with an embodiment of the present disclosure.
[0099] As illustrated in FIG. 5, the ND fixed device 104 such as the OD-CPE has an LPA manager/a LPA proxy 502 and an LPA SDK 504. Further, the wireless terminal 102 such as the smartphone or a cellular device with a user interface (UI) has a companion application 506 (similar to the companion application 110 shown in FIG. 1).
[00100] In an embodiment, the ND fixed device 104 and the wireless terminal 102 may establish a connection 508 via either a wired or wireless network. This connection may utilize various technologies such as but not limited to Bluetooth, universal Serial Board (USB), mobile hotspot, ethernet tethering etc.. Bluetooth tethering may be used to provide data connectivity to the ND fixed device 104 to perform Remote SIM Provisioning (RSP) Operations. The companion application 506 such as an LPA UI or a Web graphical user interface (GUI) may provide a mechanism to add or manage the eSIM profile on the ND fixed device 104. On triggering the eSIM profile download on the companion application 506, the LPA SDK 504 present at the ND fixed device 104 may initiate a HTTPS connection 510 to a default SM-DP+ to download the functional profile over a ES9+ interface. In an embodiment, the SM-DP+ URL may be pre-configured inside the LPA SDK 504 or the eUICC.
[00101] In an embodiment, two steps for execution of the APIs may be provided by the LPA proxy/the LPA manager 502. The first execution step may be to determine services and/or characteristics to connect with the ND fixed device 104 over a Bluetooth connection 508. The second execution step may be to use the REST API to do the RSP operation and receive the network or the ND fixed device 104 related information.
[00102] In an embodiment, the WebGUI flow may be primarily used for detailed level configurations by the service engineer and may be used for refurbishment of the ND fixed device 104. As may be appreciated, the WebGUI may be a device admin panel and may be used for normal device configurations as well.
[00103] In an embodiment, the companion application 506 may raise an API call for downloading and enabling the functional profile. After successful installation of the functional profile, an ODM application that includes, for example, the LPA manager/the LPA proxy 502 may trigger an enableProfile command. Once the functional profile is successfully downloaded and enabled on the ND fixed device 104, then the ODM application may return a positive result or a negative result to the companion application 506 being executed on the wireless terminal 102.
[00104] In an embodiment, when the result is negative then the ND fixed device 104 may return an error code to the companion application 506. As may be appreciated, the ND fixed device 104 may be a mobile network operator (MNO) device and a SM-DP+ address may be pre-configured inside the LPA SDK 504 or the eUICC. This configuration may help prevent downloading of unwanted MNO profiles onto the CPE. As may be appreciated, the above discussed mechanisms may be used for a ND fixed cellular device or any other similar M2M cellular device.
[00105] FIG. 6 illustrates a sequence flow 600 for downloading a functional profile on an embedded universal integrated circuit card (eUICC) of the ND fixed device 104, in accordance with an embodiment of the present disclosure. With respect to FIG. 6, the ND fixed device 104 and the wireless terminal 102 may be connected over either a wired or a wireless network connection. The ND fixed device 104 may, at 602, transmit one or more attributes of a selected PLMN priority cell of an available one or more PLMN priority cells to the connected wireless terminal 102. The one or more attributes of the selected PLMN priority cell may be at least one of a cell ID, throughout, and signal strength.
[00106] If the one or more attributes of the selected PLMN priority cell fulfil a pre-determined condition and are accepted, then, at step 604, a re-orientation instruction may be received from the wireless terminal 102 for re-orienting the ND fixed device 104 to camp onto the selected PLMN priority cell. On receiving an instruction from the wireless terminal 102, the ND fixed device 104 may, at 606, initiate a request for downloading the functional profile from a profile maintaining server 108. The functional profile may be a Global System for Mobile Communications Association (GSMA) consumer eUICC. On completion of the downloading of the functional profile, the ND fixed device 104 may enable the functional profile. In addition, the ND fixed device 104 may, at 608, send an error free code to the wireless terminal 102, upon a successful downloading and enabling of the functional profile at the ND fixed device 104. In case the downloading and enabling of the functional profile at the ND fixed device 104 is unsuccessful, an error-code may be sent to the wireless terminal 102.
[00107] FIG. 7 illustrates a sequence flow 700 for receiving the functional profile from the wireless terminal 102 to be downloaded at the eUICC of the ND fixed device 104, in accordance with an embodiment of the present disclosure. With respect to FIG. 7, the wireless terminal 102 connected to the ND fixed device 104 may, at 702, receive one or more attributes of the selected PLMN priority cell of an available one or more PLMN priority cells. In response to a confirmation of the one or more attributes of the selected PLMN priority cell being accepted, the wireless terminal 102 may, at 704, send a re-orientation instruction to the ND fixed device 104, for re-orienting and camping onto the selected PLMN priority cell.
[00108] The ND fixed device 104 may, at 706, transmit an instruction to initiate a request for downloading the functional profile from the profile maintaining server 108. On completion of the downloading of the functional profile, the functional profile may be enabled at the ND fixed device 104. In addition, the wireless terminal 102 may, at 708, receive, from the ND fixed device 104, a positive result upon a successful downloading and enabling of the functional profile at the ND fixed device 104.
[00109] Therefore, the disclosed method and apparatus facilitates to allow onboarding of the eUICC capable cellular ND fixed devices by ensuring a priority cell selection and providing a good network coverage availability before downloading the functional profile. The disclosed method may allow to securely download the functional profile using a consumer ecosystem, for example, the SMDP+. The function profile may be downloaded using the companion application present on the wireless terminal, for example, the smart phone or on a WebGUI, for example, a device admin panel present on the wireless terminal.
[00110] The disclosed method and apparatus may assist in identifying the PLMN priority cell and a strongest 5G signal/coverage for the ND fixed device during installation at a customer location, thus eliminating a requirement for the additional RF signal measuring instruments or network assistance. Further, the disclosed method may facilitate and assist to remotely debug field issues during the onboarding of the ND fixed device and may provide conclusive guidance for installation of any generation of a cellular device without a display, spanning across legacy, current, and future generations, all without requiring additional logistics before the eSIM profile activation.
