[0001] This application claims priority to U.S. Provisional Application Serial No. 63 / 717,389 filed on November 7, 2024, entitled "Quick Sharing of eSIMs Across Multiple UEs," the entirety of which is incorporated by reference herein.Background

[0002] Existing implementations of User Equipment (UE) embedded subscriber identity module (eSIM) sharing operations between devices have several areas in need of improvement. Current methods of eSIM transfer were designed for the permanent transfer of an eSIM profile from one UE to another. Such transfer methods involve performing a hard switch between devices where the phone number is shared to the target device and the old device (source device) becomes inoperable with respect to voice services. After the eSIM is transferred to the target device, the source device may only regain voice services when this hard switch is now performed from the target device to the source device, a process which can take minutes end-to-end.Summary

[0003] Some example embodiments are related to a method for processing, based on signaling received from a source device, a request to perform a quick share initial setup procedure with the source device, processing, based on signaling received from the source device, an indication that a first embedded subscriber identity module (eSIM) is available for download,Attorney Doc ket No : 30134 / 99801Client Ref : P 69941US P1 wherein the first eS IM is associated with a same phone number as a second eS IM installed on the source device, downloading the first eS IM, generating instructions to install the first eS IM on an embedded universal integrated circuit card ( eUICC ) of a target device and setting the first eSIM to a passive mode , wherein the target device does not have access to voice services using the first eS IM when the first eSIM is in the passive mode .

[0005] Still further example embodiments are related to a method for processing, based on input received from a user, a request to perform a quick share initial setup procedure with a target device , processing, based on signaling received from the target device , information related to the target device, generating, for transmission to an entitlement server, a request to generate a first embedded subscriber identity module ( eS IM) for the target device, wherein the request comprises the information related to the target device , wherein the first eS IM is associated with a same phone number as a second eS IM installed on a source device , processing, based on signaling received from the entitlement server, a first indication thatAttorney Docket No: 30134 / 99801Client Ref: P69941USP1 the first eSIM is available for download and generating, for transmission to the target device, a second indication that the first eSIM is available for download to the target device.

[0006] Additional example embodiments are related to a method for processing, based on signaling received from a target device, a request to perform a quick share procedure with a source device, generating, for transmission to an entitlement server, a request to activate voice services for the target device, processing, based on signaling received from the entitlement server, an indication that the voice services are activated for the target device, setting a first embedded subscriber identity module (eSIM) of the source device to a passive mode, wherein the source device does not have access to voice services using the first eSIM when the first eSIM is in the passive mode and generating, for transmission to the target device, an indication that the first eSIM installed on the source device has been set to the passive mode, wherein a second eSIM installed on the target device is associated with a same phone number as the first eSIM installed on the source device.

[0007] More example embodiments are related to a method for processing, based on signaling received from a source device, a request to generate a first embedded subscriber identity module (eSIM) for a target device, wherein the request comprises information related to the target device, wherein the first eSIM is associated with a same phone number as a second eSIM installed on a source device, generating, for transmission to a Subscription Manager Data Preparation Plus (SM-DP+) , a message to assign the first eSIM to the target device, processing, based on signaling received from the SM-DP+, a first indication that the first eSIM is ready for download by the target device andAttorney Docket No: 30134 / 99801Client Ref: P69941USP1 generating, for transmission to the source device, a second indication that the first eSIM is ready for download by the target device.Brief Description of the Drawings

[0016] The example embodiments may be further understood with reference to the following description and the related appended drawings, like elements are provided with the same reference numerals. The example embodiments relate to quickly sharing of eSIM subscriptions across multiple devices.

[0017] The example embodiments are described with regard to a user equipment (UE) . However, reference to a UE is merely provided for illustrative purposes. The example embodiments may be utilized with any electronic component that may establish a connection to a network and is configured with the hardware, software, and / or firmware to exchange information and data with the network. Specifically, the example embodiments may be used by any device that is capable of storing and using an eSIM. Therefore, the UE as described herein is used to represent any electronic component.

[0018] The example embodiments are also described with reference to a 5G New Radio (NR) network. However, the example embodiments may also be implemented in other types of networks, including but not limited to LTE networks, future evolutions of the cellular protocol ( 6G networks) , or any other type of network that uses eSIMs.

[0019] Transferring a phone number from one device to another using current methods, e.g., Global System for MobileAttorney Docket No: 30134 / 99801Client Ref: P69941USP1Communications Association (GSMA) TS.43 or vendor specific operations, requires a hard switch between the two devices. When using such methods, the phone number moves to the target device from the source device. After the switch, the eSIM of the source device becomes inoperable with respect to voice services. When the eSIM of the source device becomes inoperable, the only way to provide the original source device with a voice services is to re-perform a hard switch between the devices but in this case, from the target device to the source device.

[0020] The current methods of eSIM transfer (e.g., subscription transfer) were only meant for the permanent transfer from one device to another and as such can take minutes for end-to-end completion. With such methods it is difficult for users to quickly switch between multiple devices while maintaining only a single phone number. For example, a user may have a first device that is used during the day but may have a more fashionable second device for use at night. The user may want to quickly switch using the first device to the second device (or vice versa) without having to maintain multiple phone numbers, e.g., the first device and the second device are associated with the same phone number. The example embodiments relate to the enhanced sharing of eSIMs between multiple devices. The example embodiments may speed up the process of sharing phone numbers between devices, from taking minutes to only seconds, enabling users to quickly switch between devices without having to do the more permanent hard switch operations currently in use.

[0021] The example embodiments are described as including a quick share setup procedure and a quick share procedure. TheAttorney Docket No: 30134 / 99801Client Ref: P69941USP1 names of the procedures are only an example and are not meant to convey any particular speed at which the procedures are performed. In addition, while the example embodiments are described as an eSIM being shared among multiple devices, each of the eSIMs described in the example embodiments is a separate profile, e.g., the eSIM installed on a first device is a different eSIM than the eSIM installed on a second device. The different eSIMs may have the same associated phone number. Thus, the sharing of eSIMs described by the example embodiments refers to different devices sharing the same phone number where only one installed eSIM is active at any one time, e.g., only one device sharing the phone number is able to access voice services via the cellular network at a single time. The example embodiments will be described in greater detail below.

[0022] Fig. 1 shows an example network arrangement 100 according to various example embodiments. The example network arrangement 100 includes a UE 110. The UE 110 may be any type of electronic component that is configured to communicate via a network, e.g., mobile phones, tablet computers, desktop computers, smartphones, phablets, embedded devices, wearables, Internet of Things (loT) devices, etc. The example network arrangement 100 also includes a UE 112. The UE 112 may be functionally equivalent to the UE 110. In the example embodiments, the UE 110 may be considered to be the device that currently has the eSIM profile in the installed state (e.g., the source device) and the UE 112 may be the device on which the user wants to install the eSIM (e.g., the target device) using the example eSIM sharing operation. An actual network arrangement may include any number of UEs being used by any number of users and also that any one user may have any numberAttorney Docket No: 30134 / 99801Client Ref: P69941USP1 of UEs. Thus, the example of two UEs 110 and 112 is merely provided for illustrative purposes.

[0023] The UEs 110 and 112 may be configured to communicate with one or more networks. In the example of the network configuration 100, the network with which the UEs 110 and 112 may wirelessly communicate is a 5G NR radio access network (RAN) 120. However, the UE 110 may also communicate with other types of networks (e.g., 5G cloud RAN, a next generation RAN (NG-RAN) , a legacy cellular network, etc.) and the UE 110 may also communicate with networks over a wired connection. With regard to the example embodiments, the UEs 110 and 112 may establish a connection with the 5G NR RAN 120. Therefore, the UE 110 may have a 5G NR chipset to communicate with the NR RAN 120. The UEs 110 and 112 may communicate with the one or more networks when an eSIM profile is installed and active on the UE . In the example embodiments, an eSIM may only be active on a single UE at a time, e.g., the eSIM may only be active on the UE 110 or the UE 112 at one time. The example embodiments will describe the quick share initial setup procedure and the quick sharing of eSIMs between the UEs 110 and 112 in more detail.

[0024] The 5G NR RAN 120 may be portions of a cellular network that may be deployed by a network carrier (e.g., Verizon, AT&T, T-Mobile, etc.) . The RAN 120 may include cells or base stations that are configured to send and receive traffic from UEs that are equipped with the appropriate cellular chip set. In this example, the 5G NR RAN 120 includes the gNB 120A. However, reference to a gNB is merely provided for illustrative purposes, any appropriate base station or cell may be deployedAttorney Docket No: 30134 / 99801 Client Ref: P69941USP1(e.g., Node Bs, eNodeBs, HeNBs, eNBs, gNBs, gNodeBs, macrocells, microcells, small cells, femtocells, etc.) .

[0025] Any association procedure may be performed for the UEs 110 and 112 to connect to the 5G NR RAN 120. For example, as discussed above, the 5G NR RAN 120 may be associated with a particular network carrier where the UE 110 and / or the user thereof has a contract and credential information (e.g., as indicated in the eSIM) . Upon detecting the presence of the 5G NR RAN 120, the UE 110 may transmit the corresponding credential information to associate with the 5G NR RAN 120. More specifically, the UEs 110 and 112 may associate with a specific cell (e.g., gNB 120A) .

[0026] The network arrangement 100 also includes a cellular core network 130, the Internet 140, an IP Multimedia Subsystem (IMS) 150, and a network services backbone 160. The cellular core network 130 manages the traffic that flows between the cellular network and the Internet 140. The IMS 150 may be generally described as an architecture for delivering multimedia services to the UEs 110 and 112 using the IP protocol. The IMS 150 may communicate with the cellular core network 130 and the Internet 140 to provide the multimedia services to the UEs 110 and 112. The network services backbone 160 is in communication either directly or indirectly with the Internet 140 and the cellular core network 130. The network services backbone 160 may be generally described as a set of components (e.g., servers, network storage arrangements, etc.) that implement a suite of services that may be used to extend the functionalities of the UE 110 in communication with the various networks.Attorney Docket No: 30134 / 99801Client Ref: P69941USP1

[0027] Fig. 2 shows an example UE 110 according to various example embodiments. The UE 110 will be described with regard to the network arrangement 100 of Fig. 1. The description of the UE 110 may also apply equally to the UE 112. The UE 110 may represent any electronic device and may include a processor 205, a memory arrangement 210, a display device 215, an input / output (I / O) device 220, a transceiver 225, and other components 230. The other components 230 may include, for example, an audio input device, an audio output device, a battery that provides a limited power supply, a data acquisition device, ports to electrically connect the UE 110 to other electronic devices, sensors to detect conditions of the UE 110, etc. The UE 110 may also include an Embedded Universal Integrated Circuit Card (eUICC) 240 that may be a hardware component embedded into the UE 110 and configured to store a number of carrier profiles including the eSIM that is to be shared among the multiple devices .

[0028] The processor 205 may be configured to execute a plurality of engines for the UE 110. For example, the engine may include an eSIM quick share engine 235 for performing operations related to sharing eSIMS between the UE 110 and the UE 112. The eSIM quick share engine 235 may perform operations including, but not limited to, getting target device information from the target device 112, sending a message to the target device 112 that indicates the new eSIM is ready for the target device 112, and receiving a message from the target device 112 that indicates that the new eSIM has been installed on the target device 112 and that it has been set to the passive mode. Each of these operations are described in greater detail below.Attorney Docket No: 30134 / 99801Client Ref: P69941USP1

[0029] The above referenced engine being an application (e.g., a program) executed by the processor 205 is only an example. The functionality associated with the engines may also be represented as a separate incorporated component of the UE 110 or may be a modular component coupled to the UE 110, e.g., an integrated circuit with or without firmware. For example, the integrated circuit may include input circuitry to receive signals and processing circuitry to process the signals and other information. The engines may also be embodied as one application or separate applications. In addition, in some UEs, the functionality described for the processor 205 is split among two or more processors such as a baseband processor and an applications processor. The example embodiments may be implemented in any of these or other configurations of a UE .

[0030] The memory arrangement 210 may be a hardware component configured to store data related to operations performed by the UE 110. The display device 215 may be a hardware component configured to show data to a user while the I / O device 220 may be a hardware component that enables the user to enter inputs. The display device 215 and the I / O device 220 may be separate components or integrated together such as a touchscreen.

[0031] The transceiver 225 may be a hardware component configured to establish a connection with the 5G-NR RAN 120. Accordingly, the transceiver 225 may operate on a variety of different freguencies or channels (e.g., set of consecutive frequencies) . The transceiver 225 includes circuitry configured to transmit and / or receive signals (e.g. , control signals, data signals) . Such signals may be encoded with information implementing any one of the methods described herein. The processor 205 may be operably coupled to the transceiver 225 andAttorney Docket No: 30134 / 99801Client Ref: P69941USP1 configured to receive from and / or transmit signals to the transceiver 225. The processor 205 may be configured to encode, decode and / or process signals (e.g., signaling from a base station of a network) for implementing any one of the methods described herein.

[0032] In the example of Fig. 2, the processor 205 and the RF circuitry (e.g., transceiver 225) are illustrated as separate components. However, in some example embodiments, the RF circuitry and the processing circuitry may be integrated into the same chip, e.g., a system on chip that includes a baseband processor and RF circuitry.

[0033] As described above, in the example embodiments, the UE 110 may be considered to be the source device, e.g., the device that currently has the eSIM profile that is in the active state. The UE 112 may be considered to be the target device, e.g., the device with which the eSIM profile is to be shared. For example, eSIM quick share engine 235 may be used by the source device (e.g., the UE 110) to perform the operations described below during the example sharing operations. Similarly, the eSIM quick share engine 235 may be used by the target device (e.g., the UE 112) to perform the operations described below during the example quick share operations.

[0034] The example embodiments relate to improved operations for sharing eSIMs across multiple devices. The example embodiments relate to eSIM sharing between devices which are logged into a common cloud account, e.g., an iCloud account, a Samsung Cloud account, a Huawei Cloud Stack (HCS) account, etc. The user may want to use one phone number shared between multiple devices. At the same time, service providers do notAttorney Docket No: 30134 / 99801Client Ref: P69941USP1 want multiple devices to simultaneously use the same phone number. The quick share procedure may allow the phone number to be shared seamlessly between the multiple devices and may take only a few seconds to complete. In addition to the operations detailed below, the quick share procedure uses the syncing of data between devices via existing connectivity mechanisms, e.g., cloud accounts, and a carrier capability to perform the activation / reactivation of the devices that are sharing the eSIM. The following describes these examples use cases in greater detail.

[0035] The example embodiments relate to the quick share of eSIMs between devices. In a first aspect of the example embodiments, a quick share initial setup procedure is described, e.g., the setup procedure to prepare the devices to share the eSIMs. In a second aspect of the example embodiments, a quick share procedure is described, e.g., the sharing of the eSIMs among the devices. Throughout the remainder of this description, the UE 110 may be understood to be the source UE, and the UE 112 may be understood to be the target UE .

[0036] Fig. 3 shows a call flow 300 for a quick share initial setup according to various example embodiments. After the quick share initial setup, the devices may have the ability to quickly share eSIMs. The call flow 300 shows the quick share initial setup being performed between the source device 110 and the target device 112. The call flow 300 also includes various other components that are described in greater detail below. In the example of Fig. 3, the source device 110 and the target device 112 are shown as including two components, an application processor (AP) and an eUICC 306 and 308. The AP may be theAttorney Docket No: 30134 / 99801 Client Ref: P69941USP1 component that is executing the eSIM quick share engine 235 described above (on both the source device 110 and the target device 112) . Although, it is possible that a separate processor (e.g., baseband processor or other processor) executes the eSIM quick share engine 235. As described above, the eUICC on the source device 110 and the target device 112 may store the eSIM.

[0037] In the example of Fig. 3, at the start of the call flow 300, the source device 110 currently has the eSIM stored on the eUICC 306 in an active state. The original provisioning of the source device 112 with the eSIM is beyond the scope of this disclosure and may be performed in any manner.

[0038] The other components shown in the call flow 300 of Fig. 3 includes an entitlement server 302 and a Subscription Manager Data Preparation Plus (SM-DP+) 304. The entitlement server 302 may be a network element that may enable over-the-air configuration of eSIMs and the act ivation / reactivat ion operations for eSIMs performed by the carrier as described in more detail below with respect to Figs. 3 and 4. The SM-DP+ 304 may be a network element (typically a server) that prepares, stores, and protects carrier profiles (including operator credentials) . The SM-DP+ 304 may also download and install profiles to a UE eUICC (e.g., the eUICC 240) . Other entities or networks may refer to the entitlement server or the SM-DP+ by other names.

[0039] In 310, the quick share setup procedure is initiated at the source device 110. This may be initiated by a user through an interaction on the user interface of the source device 110. The user may initiate this procedure to occurAttorney Docket No: 30134 / 99801Client Ref: P69941USP1 between the source device 110 and any device that is associated with the same cloud service, e.g., the target device 112. For example, source device 110 and target device 112 may be associated with the same cloud service account. In some example embodiments, the source device 110 and the target device 112 may be in close proximity to one another. Thus, the source device 110 may send the set up quick share initiation request to the target device 112 using any short range protocol or communication method such as Bluetooth, short range WiFi, Near field communications (NFC) , infrared, etc. However, the source device 110 and the target device 112 are not required to be in close proximity to perform the operations of the quick share procedure. In some example embodiments, in response to the initiation request, the user may signal the intent to begin the quick share setup procedure with an acknowledgment at the target device 112, e.g., by interacting with the user interface of the target device, using face identification or any other biometric verification at the target device 112 to begin the quick share setup procedure.

[0040] In 320, device information may be exchanged between the target device 112 and the source device 110 to assist in setting up the ability to quick share eSIMs between the devices. For example, the source device 110 may receive an International Mobile Equipment Identity (IMEI) and an embedded identity document (EID) from the target device 112. In some example embodiments, the source device 110 may receive the information related to the target device 112 from the common cloud account rather than from the target device 112 directly. In addition, while this example is describing that the information related to the target device 112 is received by the source device 110 during the initiation of the quick share setup procedure, thisAttorney Docket No: 30134 / 99801Client Ref: P69941USP1 information may be shared with the source device 110 prior to the initiation of the quick share setup procedure.

[0041] In 330, the source device 110 transmits a sign up for SIM service request to the entitlement server 302. The sign up for SIM service request informs the entitlement server 302 that a new eSIM profile is to be created for the target device 112. The sign up for SIM service request 330 may include any information that assists with the setup such as the Integrated Circuit Card Identification profile (ICCID) of the source device 110, an embedded identity document (EID) of the source device 110, an EID of the target device 112, and an International Mobile Equipment Identity (IMEI) of the target device 112.

[0042] In 335, the entitlement server 302 transmits an assign a new eSIM message to the SM-DP+ 304 including the EID of the target device. In response to this message, at 340, the SM-DP+ prepares a new eSIM for the target device 112 that includes the same phone number as the phone number of the source device 110. The SM-DP+ then sends an eSIM ready message to the entitlement server indicating that the new eSIM is ready to be assigned to the target device 112. In 345, the entitlement server 302 sends a message to the source device 110 that indicates the new eSIM is ready. Then, at 350, the source device 110 sends a message to the target device 112 that indicates the new eSIM is ready for the target device 112.

[0043] At 355, the target device 112 contacts the SM-DP+ 304 and downloads the new eSIM from the SM-DP+ 304. Since the target device 112 does not currently have an active eSIM, the target device 112 may contact the SM-DP+ via a non-cellular connection,Attorney Docket No: 30134 / 99801Client Ref: P69941USP1 e.g., via Wi-Fi or any other manner of data connectivity. In some example embodiments, the target device 112 may have limited cellular data connectivity to contact the download the eSIM profile from the SM-DP+ 304 via the cellular network.

[0044] In 360, the target device 112 installs the eSIM on the eUICC 308. In 365, the eUICC 308 sends an acknowledgement to the AP of the target device 112 that the eSIM profile has been installed. In 370, the target device 112 AP sets the eSIM profile to the passive mode. At this point, while the eSIM is installed on the target device 112, the eSIM is in the passive mode such that the target device 112 is not capable of voice services using the phone number of the eSIM. In 375, the eUICC 308 of the target device 112 sends an acknowledgement message to the AP of the target device 112 indicating that the eSIM is set to the passive mode.

[0045] In 380, the target device 112 sends a message to the source device 110 indicating that the new eSIM is installed on the target device 112 and that it has been set to the passive mode. In 385, the quick share setup procedure is complete and this may be indicated to the user of the source device 110 and / or target device 112, e.g., via a user interface or any other manner of alerting the user. The eSIM of the source device 110 remains in the active state and thus has access to both call services and data services. The eSIM of the target device 112 is in the passive state and thus may only have access to data services. Since the quick share setup procedure has been completed at the target device 112, the target device 112 is now in a position for the source device 110 to quickly share theAttorney Docket No: 30134 / 99801Client Ref: P69941USP1 phone number with the target device 112 using the quick share procedure (detailed in Fig. 4) .

[0046] Fig. 4 shows a call flow 400 for a quick share procedure between multiple devices according to various example embodiments. The call flow 400 is again performed between the source device 110 and the target device 112 when a user wants to share the eSIM from the source device 110 to the target device 112, e.g., the phone number from source device 110 may be quickly shared with the target device 112 by setting the eSIM of the source device 110 to the passive mode and the eSIM of the target device 112 to the active mode. The quick share procedure may be performed any time after the quick share setup procedure as shown in Fig. 3 has been completed. The components that may be involved in the call flow 400 are the same as the call flow 300, e.g., source device 110 (including eUICC 306) , target device 112 (including eUICC 308) , entitlement server 302 and SM- DP+ 304.

[0047] In 410, a user may initiate the quick share procedure with the target device 112. The quick share procedure may be initiated in any number of ways. For example, a user may interact with user interface of the source device 110 to indicate the intent to initiate the quick share procedure. Similar to the quick share setup procedure, the target device 112 may further use face identification of the user (or any other authentication method) at the target device 112 to begin the quick share procedure operations. In some example embodiments, the target device 112 may determine whether to initiate the quick share procedure based on user intent. For example, the target device 112 may determine that the user hasAttorney Docket No: 30134 / 99801Client Ref: P69941USP1 begun using the target device 112, e.g., when the user unlocks the target device, launches / uses an application, etc. At the same time, it may be apparent that the user is not using the source device 110, e.g., the source device 110 is locked and no applications are being used. This status of the source device 110 may be shared with the target device via a short range communication as described above. Thus, the target device 112 may determine that the quick share procedure should be activated to allow the user to quickly switch to the device being used, e.g., the target device 112.

[0048] In 420, the target device 112 may send a request quick share message to the source device 110 in response to the initiation of the quick share procedure by the user. The request quick share message may include information that assists with carrying out the quick share procedure such as the ICCID of the target device 112.

[0049] In 430, the source device 110 may send a swap phone service request to the entitlement server 302. The swap phone service request 430 may include at least the ICCID of the source device 110 and the ICCID of the target device 112. In 435, the entitlement server 302 may acknowledge to the source device 110 that the swap phone service request has been received allowing the quick share procedure to continue.

[0050] In 440, the AP of the source device 110 may indicate to the eUICC 306 to change the eSIM from the active mode to the passive mode. In 445, the eUICC 306 sets the eSIM to the passive mode and sends an acknowledgment message to the AP of the source device 110 indicating the eSIM of the source device 110 has beenAttorney Doc ket No : 30134 / 99801 Client Ref : P 69941US P1 set to the passive mode . At this point, the source device 110 may receive data services but no longer has access to voice services .

[0051] In 450 , the source device 110 indicates to the target device 112 that the eSIM of the source device 110 has been set to the passive mode . In 455, the AP of the target device 112 may send an indication to the eUICC 308 that the eS IM of the target device 112 may be set to the active mode . In 460 , the eUICC 308 of the target device 112 sets the eS IM to the active mode and sends an acknowledgement to the AP of the target device 112 that the eS IM has been set to the active mode .

[0052] In 465, the guick share eS IM is ready at the target device and the AP of the target device may indicate this status to the user of the target device, e . g . , via user interface or any other method . In 470 , the user of the target device 112 may initiate voice services on the target device 112 because the quick share procedure for sharing the SIMs between the source device 110 and the target device 112 is complete meaning the target device 112 has access to voice and data services .

[0053] While the operations of the call flow 400 show the guick share of the eSIM from the source device 110 to the target device 112 , the same call flow may be used to share the eS IM back to the original source device 110 when the user wants to switch back to using the original source device . In this scenario , the target device 112 may perform the operations of the call flow 400 described for the source device 110 and the source device 110 may perform the operations of the target device 112 .Attorney Docket No: 30134 / 99801Client Ref: P69941USP1

[0054] In addition, while the example embodiments are described as the sharing of eSIMs between two devices, e.g., source device 110 and target device 112, the example embodiments may be extended to multiple devices, e.g., three or more devices that are associated with the same cloud account. For example, the initial quick share setup procedure may be performed between the source device 112 (or the target device 112) and a third device. The fact that the third device is now available for quick share may be communicated to the other device that did not perform the initial quick share setup procedure with the third device via information in the cloud account. When the user wants to share the eSIMs between the source device 110 or the target device 112 and the third device, the call flow 400 may be performed in a similar manner as described above.

[0055] Fig. 5 shows a flow chart of the source device and the target device during the quick share initial setup according to various example embodiments. The operations of 510 to 514 may correspond to operation 310 of Fig. 3, e.g., operations 510 to 514 demonstrate a user initiating the quick share setup procedure. In 510, the user may open the settings menu (or any appropriate menu) of the source device 110. In 511, the user may select an option to begin the eSIM quick share setup procedure. In 512, the user may select a device for which the eSIM quick share setup procedure is to be performed. For example, the settings menu of the source device 110 may include a list of devices that are associated with a same cloud account as the source device 110 for which the quick share procedure is available. The user may select the device with which the quick share setup procedure is to be performed, e.g., the target device 112. In 513, user intent to begin the quick share setup procedure is obtained. For example, the user may confirm thatAttorney Docket No: 30134 / 99801Client Ref: P69941USP1 they want to begin the procedure with the selected device e.g., the target device 112. In some example embodiments, this confirmation may not include any verification, e.g., the user may simply confirm the selection of the target device 112. In other example embodiments, the confirmation may include a user verification, e.g., face detection, fingerprint detection, PIN input, etc. In 514, the initiation of the quick share setup procedure may be confirmed at the target device 112. For example, the user may confirm by interacting with the UI of the target device 112. In some example embodiments, user verification through an ID challenge may be used, e.g., face detection, fingerprint detection, PIN input, etc.

[0056] The operation 520 may correspond to the operation 320 of Fig. 3, e.g., the operation 520 demonstrates the exchanging of device information between the source device 110 and the target device 112. For example, the source device 110 may obtain the IMEI and the EID from the target device 112. Any other information may be exchanged between the source device 110 and the target device 112 to assist with the quick share setup procedure. The purpose of this operation is to establish trust between the two devices.

[0057] The operation 530 may correspond to the operation 330 of Fig. 3, e.g., the operation 530 demonstrates the source device 110 initiating the quick share setup with the entitlement server 302. The operations performed between the entitlement server 302 and the SM-DP+ 304 are not shown in Fig. 5 but when successful, the source device 110 will receive the acknowledgment from the entitlement server 302 that the eSIM for the target device 112 is ready, e.g., operation 345 of Fig. 3.Attorney Docket No: 30134 / 99801Client Ref: P69941USP1In 550, the source device 110 may indicate to the target device 112 that the quick share eSIM is ready. The operation 550 may correspond to the operation 350 of Fig. 3. In 555, the target device 112 downloads the new eSIM from the SM-DP+ 304. The operation 555 may correspond to the operation 355 of Fig. 3. In 560 and 565, the source device 110 and the target device 112 have respectively completed the quick share setup.

[0058] Fig. 6 shows a flow chart of the source device and target device during the quick share of eSIMs initiated based on user intent according to various example embodiments. In 605, the eSIM of the source device 110 is in the active mode and the source device 110 is in a locked / static state, e.g., not being used by a user. In 610, the user initiates the quick share procedure at the target device 112, which corresponds to the operation 410 of Fig. 4. In 615, the initiation of the quick share procedure is confirmed at the target device. As described above, in some example embodiments, for added security the procedure may be confirmed using user verification via an ID challenge, e.g., e.g., face detection, fingerprint detection, PIN input, etc.

[0059] In 620, the target device 112 requests the quick share procedure with the source device 110 that remains depicted as static or locked at operation 625. As described above, the request by the target device 112 may be performed via short range communication but other manners of communicating the request may be used. The operation 620 may correspond to the operation 420 of Fig. 4.Attorney Docket No: 30134 / 99801Client Ref: P69941USP1

[0060] In 630, the static / locked source device 110 initiates the quick share operation with the entitlement server 302. The operation 630 may correspond to the operation 430 of Fig. 4. The operation 650 depicts the quick share procedure being complete at the source device 110, which corresponds to the operation 445 of Fig. 4. The operation 655 shows an indication of the quick share being sent by the source device 110 to the target device 112, e.g. the source device 110 sends an acknowledgment to the target device 112 that the eSIM of the source device 110 has been set to the passive state as also shown by operation 450 of Fig. 4. In 665, the eSIM of the target device 112 is enabled, which corresponds to the operation 465 of Fig. 4, where the target device 112 may use voice and / or data services using the activated eSIM.

[0061] Fig. 7 shows a user interface of the source device during the quick share initial setup according to various example embodiments. The UI 710 of the source device 110 is shown before any of the operations to initiate the quick share setup procedure have been initiated. The UI 720 of the source device 110 shows the UI 720 that corresponds to the operation 512 as depicted in Fig. 5. More specifically, using the UI 720, a user may select a target device that is associated with the same cloud account as the source device 110 with which to initiate the quick share set up procedure. In Fig. 7, the associated devices are depicted as 725a and 725b on the UI 720 of the source device 110 and represent two potential target devices with which the source device 110 may quick share eSIMs.

[0062] Fig. 8 shows a user interface of the source device and the target device during the quick share of eSIM procedure according to various example embodiments. More specifically,Attorney Docket No: 30134 / 99801Client Ref: P69941USP1Fig. 8 depicts the "user intent" approach of initiating the quick share procedure. At 810a, the eSIM of the source device 110 is in the active state but the source device 110 is not being used by a user. This is shown by the UI of the source device 110 indicating cellular bars, WiFi bars and battery life. Simultaneously, at 810b, the user "grabs" the target device 112 to indicate user intent to use the target device 112. At 815a, the eSIM of the source device 110 remains in the active state but the source device 110 is still not being used, e.g., UI depicting cellular bars, WiFi bars and battery life. Simultaneously, at 815b, the user is now holding the target device 112 but has not started using the target device and the eSIM of the target device 112 is in the passive state, e.g., the UE of the target device 112 only shows WiFi bars and battery lif e .

[0063] At 820a, the eSIM of the source device 110 remains active and not being used, e.g., UI depicting cellular bars, WiFi bars and battery life. Simultaneously, at 820b, the user unlocks the target device 112 and begins using it, allowing the quick share procedure to be initiated based on the user' s intent to use the target device 112. At 820b, the eSIM of the source device 112 is still in the passive mode but the quick share procedure has begun, e.g., the UE of the target device 112 only shows WiFi bars and battery life. At 825a, the quick share procedure has been completed and the eSIM of the source device 110 is now in the passive mode and thus has no access to call services but does have access to data services, e.g., the UE of the source device 110 only shows WiFi bars and battery life. At 825b, the quick share procedure has been completed and now the eSIM of the target device 112 is in the active state and thus has access to both call services and data services, e.g., the UEAttorney Docket No: 30134 / 99801Client Ref: P69941USP1 of the target device 112 shows cellular bars, WiFi bars and battery life. In this example, when it is stated that a device with the passive eSIM only has data access, this may refer to data access via WiFi networks or may also refer to data access via a cellular network.

[0064] Thus, the example embodiments described above allow for a user to share eSIMs among multiple devices in a fast manner. In addition, the example embodiments also satisfy the carriers desire to only have a phone number associated with multiple eSIMs active on a single device at a time. Thus, the example embodiments may satisfy the desires of the user and the carrier with which a user has a subscription.

[0065] Issues similar to those surrounding the sharing of eSIM credentials may also apply to sharing credentials for various third-party applications. For instance, in certain third party messaging applications such as WhatsApp, Telegram, WeChat, Line, Kakao, etc., the credentials for the applications may be associated with a device making it difficult to switch between devices and keep the information associated with the credentials, e.g., phone number, messaging name, etc. For instance, when you open WhatsApp on a new device, the chat history may not be updated because the backup on, e.g., a cloud service, may not be updated. A similar quick share method as applied to eSIMs may be used to handle the similar problem applied to third party applications. For example, an application programming interface (API) may provide an indicator to applications to switch between active and passive mode similar to what was described above with respect to eSIM sharing. For example, the user may have the same credentials for the third party application on a first device and a second device but theAttorney Docket No: 30134 / 99801Client Ref: P69941USP1 credentials may be set to active on the first device and passive on the second device. When the user wants to switch devices, a procedure similar to the quick share procedure described above may be initiated (e.g., using APIs resident on the first device and the second device) to allow the credentials of the first device to be set to the passive mode and the credentials of the second device to be set to the active mode.

[0066] In the above example embodiments, it was described that voice services were transferred when the eSIMs are shared. However, this is only an example, and the sharing of the eSIMs may result in other operations or services being shared. For example, a carrier may implement an entitlement server flow that causes other operations (e.g., in addition to or exclusive of the transfer of voice services) to be performed during the sharing of eSIMs. These other operations may allow the carrier to prevent the simultaneous use of multiple eSIMs in a manner that does not exclusively rely on the device SIM management states (e.g., active / passive modes) . For example, in some example embodiments, all services (e.g., voice and data services) may be temporarily deactivated at the carrier side when an eSIM is in passive mode. In these example embodiments, a bootstrap capability may be introduced to maintain connectivity to the ecosystem, so the states may be maintained and changed. The bootstrap capability may refer to an eSIM that is loaded onto the device that is hidden from the user. This bootstrap eSIM is a different eSIM from the eSIM being shared among the devices. The bootstrap eSIM may camp and register onto a cellular network but is hidden from the user. The bootstrap eSIM may support a limited set of allowed data traffic. This allowed data traffic may include receiving information from the networkAttorney Docket No: 30134 / 99801Client Ref: P69941USP1 to change the state of the device eSIM, e.g., from passive mode to active mode.

[0067] In other example embodiments, only the voice services may be disabled on the carrier side and the device maintains the passive state locally, e.g., the device may maintain data connectivity such that the device may receive information from the network to change the state of the device eSIM, e.g., from passive mode to active mode.

[0068] In further example embodiments, voice services may be disabled on the carrier side and data service may be set into a restricted mode that only allows the passive eSIM service to access quick switch related services, e.g. , the only data services available to the device is the capability to receive information from the network to change the state of the device eSIM, e.g., from passive mode to active mode.Examples
