Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. non-provisional patent application No. 17 / 804,415, filed on May 27, 2022, entitled “DISABLEMENT AND RECOVERY FOR LOST OR STOLEN USER DEVICE,” which is hereby expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for disabling and recovering lost or stolen user equipment. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more base stations that support communications for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. A "downlink" (or "DL") refers to the communication link from a base station to a UE, and an "uplink" (or "UL") refers to the communication link from a UE to a base station.

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink, using CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation, so as to better support mobile broadband Internet access. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0020] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of protection of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such a device or method implemented using other structures, functions, or structures and functions in addition to or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

[0021] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0022] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT, and / or post-5G RATs (e.g., 6G).

[0023] Figure 1 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d), a user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other network entities. The base station 110 is an entity that communicates with the UE 120. The base station 110 (sometimes referred to as a BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and / or a transmit receive point (TRP). Each base station 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​a base station 110 and / or a base station subsystem serving the coverage area, depending on the context in which the term is used.

[0024] Base station 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UE 120 associated with the femto cell (e.g., UE 120 in a closed subscriber group (CSG)). A base station 110 for a macro cell may be referred to as a macro base station. A base station 110 for a pico cell may be referred to as a pico base station. A base station 110 for a femto cell may be referred to as a femto base station or a home base station. In Figure 1 In the example shown, BS 110a may be a macro base station for macrocell 102a, BS 110b may be a pico base station for picocell 102b, and BS 110c may be a femto base station for femtocell 102c. A base station may support one or more (eg, three) cells.

[0025] In some examples, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of the mobile base station 110 (e.g., a mobile base station). In some examples, the base stations 110 may be interconnected with each other and / or to one or more other base stations 110 or network nodes (not shown) in the wireless network 100 using any suitable transport network through various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0026] The wireless network 100 may include one or more relay stations. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a base station 110 or a UE 120) and transmit transmissions of data to a downstream station (e.g., a UE 120 or a base station 110). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown, BS 110d (eg, a relay base station) may communicate with BS 110a (eg, a macro base station) and UE 120d to facilitate communication between BS 110a and UE 120d. A base station 110 that relays communications may be referred to as a relay station, relay base station, relay, or the like.

[0027] The wireless network 100 may be a heterogeneous network including different types of base stations 110, such as macro base stations, pico base stations, femto base stations, relay base stations, etc. These different types of base stations 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro base station may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico base station, a femto base station, and a relay base station may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0028] A network controller 130 may be coupled to or in communication with a set of base stations 110 and may provide coordination and control for the base stations 110. The network controller 130 may communicate with the base stations 110 via backhaul communication links. The base stations 110 may also communicate directly with each other or indirectly via wireless or wired backhaul communication links.

[0029] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or components in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a radio access network (RAN) node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR base station (BS), a 5G NB, a gNodeB (gNB), an access point (AP), a TRP or a cell) or one or more units (or one or more components) performing base station functionality can be implemented as an aggregated base station (also known as a stand-alone base station or a monolithic base station) or a decomposed base station. "Network entity" or "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more central units (CU), one or more distributed units (DU), one or more radio units (RU), or a combination thereof).

[0030] A converged base station may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some aspects, a CU may be implemented within a RAN node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed in one or more other RAN nodes. A DU may be implemented to communicate with one or more RUs. Each of a CU, a DU, and a RU may also be implemented as a virtual unit (e.g., a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU)).

[0031] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed base station may be used in an integrated access backhaul (IAB) network, an open radio access network (O-RAN (network configuration such as that initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0032] UE 120 may be distributed throughout wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. UE 120 may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, and / or any other suitable device configured to communicate via a wireless medium.

[0033] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0034] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0035] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more side link channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0036] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). It should be understood that, although portions of FR1 are greater than 6 GHz, FR1 is often (interchangeably) referred to as the “below 6 GHz” band in various documents and articles. Similar naming issues sometimes occur with respect to FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0037] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz–24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and therefore the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz–71GHz), FR4 (52.6GHz–114.25GHz), and FR5 (114.25GHz–300GHz). Each of these higher frequency bands falls within the EHF band.

[0038] Considering the above examples, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0039] In some aspects, a user device such as UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may: retrieve an indication of a current device state of the user device from a server; and disable communication capabilities of the user device in conjunction with a determination that the current device state is a first device state among a plurality of device states. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0040] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 Different than described.

[0041] Figure 2 2 is a diagram illustrating an example 200 of base station 110 communicating with UE 120 in wireless network 100 according to the present disclosure. Base station 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1).

[0042] At the base station 110, the transmit processor 220 may receive data intended for the UE 120 (or a set of UEs 120) from the data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQI) received from the UE 120. The base station 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-coding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0043] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the base station 110 and / or other base stations 110, and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0044] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0045] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[0046] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (eg, with reference to FIG. 3A to FIG. 3D , Figure 4 , Figure 5 and Figure 6 ).

[0047] At the base station 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component of the modem 232 shown as DEMOD), detected by the MIMO detector 236 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, the modem 232 of the base station 110 may include a modulator and a demodulator. In some examples, the base station 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., see reference 242). FIG. 3A to FIG. 3D , Figure 4 , Figure 5 and Figure 6).

[0048] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 4 The process of 400 Figure 5 10 and / or operations of process 500 and / or other processes described herein. Memory 242 and memory 282 may store data and program codes for base station 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), may cause one or more processors, UE 120, and / or base station 110 to perform or direct, for example Figure 4 The process of 400 Figure 5 In some aspects, the user equipment described herein is UE 120, is included in UE 120, or includes Figure 2 One or more components of UE 120 are shown.

[0049] In some aspects, the user device includes: a component for retrieving an indication of a current device state of the user device from a server; and / or a component for disabling communication capabilities of the user device in conjunction with a determination that the current device state is a first device state among a plurality of device states. In some aspects, the components for the user device to perform operations described herein may include, for example, one or more of the communication manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0050] Although Figure 2The blocks in the 2000 and 2010 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0051] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 Different than described.

[0052] A user device (e.g., UE 120) may include a subscriber identity module (SIM) interface that accommodates a SIM card. A SIM card may include an integrated circuit that securely stores an International Mobile Subscriber Identity (IMSI) and associated security keys that are used to identify and authenticate a corresponding subscription associated with the SIM card. A subscription associated with the SIM card may be activated to enable the user device to access a network. In some examples, the SIM card may store a list of services that the user device is entitled to access using the subscription associated with the SIM card, such as data services or voice services, etc.

[0053] In some cases, the user may lose the user device, or the user device may be stolen. When the user device is lost or stolen, the user device may be reused, and the original user of the user device has no way to retrieve the device. For example, the SIM card can be removed from the user device, and the user device can operate in Wi-Fi mode only without obtaining cellular (e.g., 4G, 5G, etc.) network services. Theft deterrence on the user device may include SIM lock and / or screen lock, etc. However, this type of theft deterrence is often circumvented. In addition, theft deterrence that relies on applications running in an unsafe environment (e.g., a high-level operating system (HLOS)) may be vulnerable to attack in order to circumvent theft deterrence. The user device retrieves an application (e.g., a "find my phone" application) that may rely on a global positioning system (GPS), which may be manually disabled on the user device. In some examples, the user device may store sensitive, important and / or private data. In such examples, the user may lose data stored on the user device and / or the data stored on the user device may no longer be private.

[0054] Some techniques and apparatus described herein enable a user device to retrieve an indication of a current device state of a user device from a server. In conjunction with a determination that the current device state is a first device state among a plurality of device states, the user device may disable the communication capabilities of the user device. For example, the first device state may be a device state associated with a lost or stolen user device. In some aspects, the user device may disable communication capabilities, including one or more SIM interfaces, Wi-Fi, a global navigation satellite system (GNSS) (e.g., GPS), Bluetooth, a peripheral connection (e.g., a universal serial bus (USB) port), and / or other communication capabilities. Therefore, an indication of the first device state on a server may remotely cause the user device to disable the communication capabilities of the user device. This may prevent the user device from being reused for a new user, which may deter the theft of the user device and the re-purchase of a stolen user device.

[0055] In some aspects, the user device may include an integrated SIM, and the user device may activate a subscription associated with the integrated SIM to provide network connectivity for the user device to communicate with a server (e.g., to retrieve device status), even if the communication capability has been disabled or the SIM card has been removed from the user device. The user device may temporarily enable communication capabilities and / or peripherals (e.g., GNSS or GPS) to obtain information (e.g., the location of the user device) and send the information to the server. The user device may then disable the communication capabilities and / or peripherals of the used device again. In this way, even if the communication capabilities of the user device are disabled to prevent reuse of the user device, the chances of the user finding or retrieving the user device may be increased.

[0056] In some aspects, in the case where the communication capabilities of the user device have been disabled, the user device may temporarily activate a subscription associated with the integrated SIM to provide network connectivity to the user device, and the user device may retrieve an indication of an updated device state of the user device from a server using the network connectivity provided by temporarily activating the subscription associated with the integrated SIM of the user device. In conjunction with the determination that the updated device state is a second device state among multiple device states, the user device may enable the communication capabilities of the user device. In this case, the second device state may be a "normal" device state associated with the user device not being lost or stolen. For example, in conjunction with the user device being found or recovered, the device state on the server may be updated to the second device state. In this way, when the user device is recovered, the communication capabilities of the user device may be restored.

[0057] FIG. 3A to FIG. 3D is a diagram illustrating an example 300 associated with disabling and recovering a lost or stolen user device according to the present disclosure. FIG. 3A to FIG. 3D As shown, example 300 includes a user device, a network entity, a theft / recovery server, and a client device.

[0058] The user equipment can be a UE (e.g., UE 120), a cellular / mobile phone (e.g., a smart phone), a PDA, a wireless communication device, a handheld device, a laptop computer, a tablet computer, a camera, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), a gaming device, a medical device, a biometric device, an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle (e.g., a smart car), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, an IoT device, or a similar type of device.

[0059] The network entity may be a base station (e.g., base station 110), an AP, a TRP, a CU, a DU, a RU, or a combination thereof. The network entity may provide access to a wireless communication network. The theft / recovery server may include a communication device and / or a computing device. For example, the theft / recovery server may include a server, such as an application server, a client server, a web server, a database server, a host server, a proxy server, a virtual server (e.g., executed on computing hardware), or a server in a cloud computing system. In some aspects, the theft / recovery server may provide services related to disabling and recovering lost or stolen user devices. In some aspects, the theft / recovery server may be an edge server at the edge of a wireless communication network (e.g., a wireless communication network associated with the network entity), and the theft / recovery server may provide the service as an edge service. In some aspects, the theft / recovery server may be a server associated with and / or controlled by a mobile network operator (MNO) of the wireless communication network.

[0060] The client device may include a communication device and / or a computing device. For example, the client device may be or may include a UE (UE 120), a wireless communication device, a cellular / mobile phone (e.g., a smart phone), a laptop computer, a tablet computer, a desktop computer, a wearable device (e.g., a smart watch, smart glasses, a head-mounted display, or a virtual reality head-mounted device), or a similar type of device.

[0061] User equipment may include one or more SIM interfaces. Figure 3AAs shown, the user equipment may include two SIM interfaces (e.g., a first SIM interface and a second SIM interface). Each SIM interface may accommodate a corresponding SIM card with an associated subscription. For example, one SIM interface may accommodate a first SIM card, and the other SIM interface may accommodate a second SIM card. The first SIM card may be a first MNO SIM associated with a first MNO subscription (e.g., MNO SIM1), and the second SIM card may be a second MNO SIM associated with a second MNO subscription (e.g., MNO SIM 2). In some aspects, the SIM interface may be an International Organization for Standardization (ISO) 7816 interface.

[0062] like Figure 3A As shown, the modem of the user equipment may include a subscriber identity module (UIM). The UIM may be a modem software component that interfaces with a SIM card via a SIM interface (e.g., an ISO 7816 interface). In some aspects, the UIM may include a communication capability module. The communication capability module may be a software component that performs disabling and / or enabling of the communication capability of the user equipment (e.g., disabling and / or enabling of the communication interface of the user equipment). For example, the communication capability module may be implemented as an instruction or code stored in a memory or a non-transient computer-readable medium and executable by a controller or a processor to perform the functions or operations described herein. In some aspects, the communication capability module may disable and / or enable the SIM interface of the user equipment (e.g., using a subscription associated with a SIM card in the SIM interface to disable and / or enable cellular communication). The communication capability module may also enable or disable other communication capabilities of the user equipment (e.g., Wi-Fi, GNSS, and / or Bluetooth, etc.).

[0063] like Figure 3A As shown, the user device may include a Wi-Fi interface (e.g., providing Wi-Fi capabilities) and a GNSS interface (e.g., providing GNSS capabilities). For example, the GNSS interface may be a GPS interface that provides GPS capabilities. Additionally or alternatively, the user device may include other communication interfaces, such as a Bluetooth interface (e.g., providing Bluetooth capabilities) and / or one or more peripheral connections or ports (e.g., USB ports) for connecting the user device to other devices, etc. Figure 3A As shown, the user device may include one or more software applications (or "apps") that allow the user to manually activate or deactivate Wi-Fi, GNSS, and / or other communication capabilities (eg, Bluetooth) of the user device.

[0064] like Figure 3AAs shown, the user device may include an integrated SIM 302. The integrated SIM 302 may be a SIM that is integrated with the user device (e.g., embedded in the user device). The integrated SIM 302 may not be physically removable from the user device. The integrated SIM 302 may have a corresponding subscription associated with the integrated SIM 302. For example, the integrated SIM 302 may include an integrated circuit embedded in the user device (and not physically removable from the user device) that stores the IMSI and the associated security key that identifies the subscription associated with the integrated SIM 302. The integrated SIM 302 may also provide network connectivity for the user device, even when the user device disables the SIM interface (e.g., SIM card slot) and Wi-Fi. In some aspects, the subscription associated with the integrated SIM 302 may be a small and / or low-cost subscription similar to IoT, which the user device may call to provide network connectivity to communicate with the theft / recovery server (e.g., a server that manages the subscription) without using the SIM interface.

[0065] In some aspects, the integrated SIM 302 may be included in a secure execution environment. The secure execution environment may include a processor component (e.g., one or more processors) and a memory component (e.g., memory) within the secure execution environment. The memory component included in the secure execution environment may store software that can be executed by the processor component included in the secure execution environment. The secure execution environment may provide software security to protect the software stored in the secure execution environment and / or (e.g., via a secure shell) to protect the hardware (e.g., the integrated SIM 302, the processing component, and the memory component) included in the secure execution environment. For example, the secure execution environment may provide hardware and / or software security that is Common Criteria certified and / or Federal Information Processing Standards (FIPS) certified. In some aspects, the integrated SIM 302 and the secure execution environment may be integrated into a system on chip (SoC) of a user device (e.g., on an integrated circuit with other components of the user device). For example, the secure execution environment may include a secure processor unit (SPU) as an authenticated secure element in the SoC, and the integrated SIM 302 may be included in the SPU.

[0066] In some aspects, the secure execution environment may include a theft / recovery module. The theft / recovery module may be a software module (or application) stored in and executed in the secure execution environment. For example, the theft / recovery module may be implemented as an instruction or code stored in a memory or non-transient computer-readable medium within the secure execution environment and executed by a controller or processor within the secure execution environment to perform the functions or operations described herein. In some aspects, the theft / recovery module may include instructions and / or logic for activating and deactivating subscriptions associated with the integrated SIM 302. In some aspects, the theft / recovery module may control the user device to communicate with the theft / recovery server to retrieve the device status of the user device. In some aspects, the theft / recovery module may transmit a command to the UIM to disable or enable the communication capabilities of the user device based at least in part on the device status of the user device.

[0067] like Figure 3A In and shown by reference numeral 304, the user (e.g., owner) of the user device can change the device state of the user device in the user portal in conjunction with the user device being lost or stolen. The user portal can be a portal with a theft / recovery server. In some aspects, the user portal can be displayed in a web browser or in another application executed on a client device. In the case where the user device is lost or stolen, the user can input the change of the device state of the user device to the user portal via the input component (e.g., keyboard, mouse, touch screen, etc.) of the client device. In some aspects, the user portal can display a prompt for the user to select the device state of the user device from a plurality of device states. For example, a plurality of device states may include a "normal" device state associated with a user device that is not lost or stolen and one or more device states associated with a user device that is lost or stolen. In some aspects, the device state associated with a lost or stolen user device may include a "disabled" device state and an "erased and disabled" device state. In this case, when the user device is lost or stolen, the user may input (via the client device) to the user portal a selection of a “disabled” device state (e.g., a change from a “normal” device state to a “disabled” device state) or a selection of a “wipe and disable” device state (e.g., a change from a “normal” device state to a “wipe and disable” device state). For example, the user may input a selection of a “disabled” device state to indicate that the communication capabilities of the user device will be disabled. The user may input a selection of a “wipe and disable” device state (e.g., where sensitive data is stored on the user device) to indicate that data stored on the user device will be wiped and the communication capabilities of the user device will be disabled.

[0068] As shown at reference numeral 306, the client device may send an indication of the device state entered into the user portal to the theft / recovery server. The theft / recovery server may store the current device state of the user device (and other user devices for which disabling and recovery services are being provided). The theft / recovery server may receive an indication of the device state resulting from a change in the device state of the user device from the client device, and the theft / recovery server may update the current device state stored for the user device.

[0069] As shown in reference numeral 308, the user device may detect a triggering event associated with retrieving the device state of the user device. In some aspects, the user device may periodically retrieve the current device state of the user device from the theft / recovery server. For example, the triggering event for retrieving the current device state of the user device may be the expiration of a polling timer of a specific duration. In this case, based at least in part on detecting that the polling timer has expired, the user device may retrieve the current device state from the theft / recovery server, and the user device may reset the polling timer each time the user device retrieves the current device state from the theft / recovery server. In some aspects, the theft / recovery module in the secure execution environment may run a polling timer and control the user device to retrieve the device state as part of a polling algorithm to determine the device state indicated by the theft / recovery server.

[0070] In some aspects, the triggering event associated with retrieving the device state from the theft / recovery server may be based at least in part on the power cycle of the user device. For example, whenever the device is powered on after being powered off, the user device may be triggered to retrieve the device state from the theft / recovery server. In some aspects, the triggering event may be based at least in part on detecting user activity of the user device. For example, after the user device is idle for a duration that satisfies a threshold, the user device may detect the triggering event associated with retrieving the device state from the theft / recovery server in conjunction with detecting user activity (e.g., detecting screen swipes or key presses, etc.). In some aspects, the theft / recovery module in the secure execution environment may detect whether the triggering event has occurred, and the theft / recovery module may control the user device to retrieve the device state from the theft / recovery server based at least in part on detecting the triggering event.

[0071] As shown by reference numerals 310 and 312, the user device may retrieve the current device state of the user device from the theft / recovery server based at least in part on detecting a triggering event. As shown by reference numeral 310, the user device may send a request for the device state to the theft / recovery server via a network entity. The theft / recovery server may receive the request for the device state from the user device via the network entity. As shown by reference numeral 312, in conjunction with receiving the request for the device state, the theft / recovery server may send an indication of the current device state of the user device (stored on the theft / recovery server) to the user device via the network entity. The user device may receive the indication of the current device state from the theft / recovery server via the network entity.

[0072] In some aspects, when the user device is operating in a default mode associated with a "normal" device state (wherein the communication capabilities of the user device are enabled), the user device may communicate with the theft / recovery server via a network entity using one or more subscriptions associated with one or more SIM cards in one or more SIM interfaces (e.g., MNO SIM1 or MNO SIM2). In some cases, the user device may attempt to communicate with the theft / recovery server using the subscription associated with the SIM card in the SIM interface to retrieve the device state, but the user device may not be able to connect with the theft / recovery server (e.g., due to some restrictions on MNO SIM subscriptions or because the user device is unable to obtain network connectivity because there is no SIM card inserted in the SIM interface). In some aspects, the user device may connect with the theft / recovery server to retrieve an indication of the current device state of the user device using a subscription associated with an integrated SIM included in the secure execution environment based at least in part on a failure to connect to the theft / recovery server using the subscription associated with the SIM interface. For example, based at least in part on being unable to connect the user device to the theft / recovery server using the MNO SIM associated with the SIM interface, the theft / recovery module may activate a subscription associated with integrated SIM 302 and instruct the UIM to communicate with the theft / recovery server using the subscription associated with integrated SIM 302. In this way, the user device may retrieve device status even when the user device is unable to establish a connection using the MNO SIM associated with the SIM interface.

[0073] In some aspects, when the user device is operating in a default mode associated with a "normal" device state, the current device state retrieved by the user device may be a "normal" device state associated with the user device not being lost or stolen. In this case, the user device may continue to operate in a default mode in which the communication capabilities of the user device are enabled.

[0074] In some aspects, when the user device is operating in a default mode associated with a "normal" device state, the current device state retrieved by the user device may be a "disabled" device state (eg, Figure 3A The user device may execute a disabling procedure (e.g., by Figure 3B 314 to 320).

[0075] like Figure 3B In the embodiment and indicated by reference numeral 314, the user device may display a disabling message on a display (e.g., a screen) of the user device based at least in part on a determination that the current device state is a “disabled” device state (or an “erased and disabled” device state). For example, the disabling message may indicate that the user device has been disabled, the user device is unavailable, the user device is faulty, the user device has been stolen, and / or the user device is being returned for service, etc. In some aspects, the theft / recovery module may control the display of the user device to display the disabling message in conjunction with a determination that the current device state is a “disabled” device state (or an “erased and disabled” device state).

[0076] As shown at reference numeral 316, in conjunction with a determination that the current device state is a "disabled" device state (or a "wipe and disabled" device state), the user device may determine the current location of the device using GNSS (e.g., GPS), and the user device may send the current location of the user device to the theft / recovery server (via a network entity). The theft / recovery server may send the current location of the user device to the client device via a user portal to provide the user with the current location of the user device. For example, the user may then report the current location of the user device to the police.

[0077] As shown in reference numeral 318, in conjunction with the determination that the current device state is a "disabled" device state (or an "erased and disabled" device state), the user device may disable the communication capabilities of the user device. For example, the user device may disable the communication capabilities of the device after the current location of the user device is sent to the theft / recovery server. In some aspects, the user device may disable the SIM interface (e.g., SIM card slot) of the user device. For example, the theft / recovery module may instruct the UIM of the modem to disable the SIM interface, and the communication capabilities module may disable the SIM interface. Disabling the SIM interface (e.g., SIM card slot) may cause the user device to operate in a limited service mode with no Internet connection, no voice over Internet protocol (VOIP), and no voice calls. In this limited service mode, only emergency calls may occur. In some aspects, the user device may disable Wi-Fi, GNSS (e.g., GPS), Bluetooth, peripheral connections (e.g., USB ports), and / or other communication capabilities of the user device. For example, the theft / recovery module may instruct the UIM of the modem to disable Wi-Fi, GNSS, Bluetooth, and peripheral connections, and the communication capabilities module may disable Wi-Fi, GNSS, Bluetooth, and peripheral connections. In some aspects, the user device (e.g., the theft / recovery module and / or the communication capabilities module) may also disable activation of communication capabilities (e.g., activation of a SIM interface, Wi-Fi, GNSS, and / or Bluetooth, etc.) by one or more applications executed on the user device. In this way, a person in possession of the user device may be prevented from manually enabling communication capabilities using an application (e.g., a "Settings" application, etc.).

[0078] As shown in reference numeral 320, in some aspects, the user device may call a recovery phone number in conjunction with a determination that the current device state is a "disabled" device state (or an "erased and disabled" device state). For example, the recovery phone number may be a phone number associated with a user of the user device. In some aspects, the indication of the current device state retrieved from the theft / recovery server may include the setting of the recovery phone number. The recovery phone number may be a phone number programmed into the user device to attempt to recover the user device for the user. In some aspects, when the user device is powered on without a SIM, Wi-Fi, and / or other communication capabilities, the user device may call the recovery phone number using a network connection provided by a subscription associated with the integrated SIM 302. For example, when in a "disabled" device state (or an "erased and disabled" device state), when powered on, when the current device state is retrieved, when an input to the user device (e.g., a screen swipe or a key press) is detected, and / or periodically, the user device may call the recovery number. This may allow the user to provide a reward and / or request the return of the user device, etc. In some aspects, the settings for the retrieval phone number may include an indication of the retrieval phone number and / or an indication of when the user device is to call the retrieval phone number. For example, the retrieval number and / or the indication of when the user device is to call the retrieval phone number may be indicated by the user (e.g., via a client device) in a user portal. In this case, the user device may call the retrieval phone number based at least in part on the settings for when to call the retrieval phone number.

[0079] like Figure 3B In and further shown by reference numeral 322, the user device may erase data stored on the user device. For example, the user device may erase data stored on the user device based at least in part on a determination that the current device state is an "erased and disabled" device state. In some aspects, the user device may execute a cryptographic erase procedure to erase data stored on the user device. In some aspects, sensitive data may be stored in a memory component protected by a secure execution environment, and the user device (e.g., a theft / recovery module) may execute a cryptographic erase procedure to erase sensitive data protected by the secure execution environment.

[0080] like Figure 3C In the embodiment and indicated by reference numeral 324, in the case where the communication capability is disabled (e.g., in a "disabled" device state or a "wiped and disabled" device state), the user device can detect a triggering event associated with retrieving the current device state from the theft / recovery server. For example, the user device (e.g., the theft / recovery module) can detect the triggering event as described above in conjunction with reference numeral 308.

[0081] As shown at reference numeral 326, the user device may activate a subscription associated with the integrated SIM 302. For example, based at least in part on detecting a triggering event, the user device may temporarily activate a subscription associated with the integrated SIM to provide network connectivity for the user device to use to communicate with a theft / recovery server to retrieve a current device status. In some aspects, the theft / recovery module may instruct the modem's UIM to initialize the integrated SIM 302 for full service to allow the theft / recovery module to control the UE to establish a connection with the theft / recovery server.

[0082] As shown by reference numerals 328 and 330, the user device may retrieve the current user status of the user device from the theft / recovery server. As shown by reference numeral 328, the user device may send a request for the device status to the theft / recovery server via the network entity. The theft / recovery server may receive the request for the device status from the user device via the network entity. As shown by reference numeral 330, in conjunction with receiving the request for the device status, the theft / recovery server may send an indication of the current device status of the user device to the user device via the network entity. The user device may receive the indication of the current device status from the theft / recovery server via the network entity. In some aspects, the user device may use the network connectivity provided by temporarily activating the subscription associated with the integrated SIM 302 to retrieve the indication of the device status of the user device. For example, the user device may use the network connectivity provided by the subscription associated with the integrated SIM 302 to send the request and receive the indication of the device status.

[0083] like Figure 3C As shown, in some aspects, the indication of the device state retrieved from the theft / recovery server may indicate that the current device state is still a "disabled" device state (or a "wiped and disabled" device state). As shown by reference numeral 332, in conjunction with the determination that the current device state is still a "disabled" device state (or a "wiped and disabled" device state) when the communication capabilities of the user device are disabled, the user device may temporarily enable GNSS to determine the current location of the user device, and the user device may send an indication of the current location of the user device to the theft / recovery server. For example, the user device may use network connectivity provided by temporarily activating a subscription associated with the integrated SIM 302 to send the current location of the user device to the theft / recovery server. The user device may then disable GNSS capabilities again. For example, the theft / recovery module may instruct the UIM (e.g., the communication capabilities module) to temporarily enable GNSS and then disable GNSS again. The theft / recovery server may send the current location of the user device to the client device via the user portal.

[0084] In conjunction with a determination that the current device state is still the "disabled" device state (or the "erased and disabled" device state), the user device may deactivate the subscription associated with the integrated SIM 302, as indicated by reference numeral 334. For example, the user device may deactivate the subscription associated with the integrated SIM 302 and return to the limited service mode after sending the current device location to the theft / recovery server.

[0085] like Figure 3D And as shown by reference numeral 336, in conjunction with the user device being found or recovered, a user (e.g., owner) of the user device may change the device state of the user device in the user portal (e.g., via a client device). For example, when the user device is found or recovered, the user may input (via a client device) a selection of a “normal” device state into the user portal (e.g., from a “disabled” device state or a “erased and disabled” device state to a “normal” device state). As shown by reference numeral 338, the client device may send an indication of the device state input into the user portal to the theft / recovery server. The theft / recovery server may receive from the client device an indication of the device state resulting from a change in the device state of the user device (e.g., a “normal” device state), and the theft / recovery server may update the current device state stored for the user device.

[0086] As indicated by reference numeral 340, in the event that the communication capability is disabled (e.g., in a "disabled" device state or a "wiped and disabled" device state), the user device can detect a triggering event associated with retrieving the current device state from the theft / recovery server. For example, the user device (e.g., the theft / recovery module) can detect the triggering event as described above in conjunction with reference numeral 308.

[0087] As shown at reference numeral 342, the user device may activate a subscription associated with the integrated SIM 302. For example, based at least in part on detecting a triggering event, the user device may temporarily activate a subscription associated with the integrated SIM to provide network connectivity for use by the user device to communicate with the theft / recovery server to retrieve the current device status, as described above in conjunction with reference numeral 326.

[0088] As shown by reference numerals 344 and 346, the user device may retrieve the current user status of the user device from the theft / recovery server.

[0089] As shown by reference numeral 344, the user device may send a request for the device status to the theft / recovery server via the network entity. The theft / recovery server may receive the request for the device status from the user device via the network entity. As shown by reference numeral 346, in conjunction with receiving the request for the device status, the theft / recovery server may send an indication of the current device status of the user device (stored on the theft / recovery server) to the user device via the network entity. The user device may receive the indication of the current device status from the theft / recovery server via the network entity. In some aspects, the user device may use network connectivity provided by temporarily activating a subscription associated with the integrated SIM 302 to retrieve an indication of the device status of the user device. For example, the user device may use network connectivity provided by the subscription associated with the integrated SIM 302 to send a request and receive an indication of the device status.

[0090] like Figure 3D As shown, in some aspects, the indication of the device state retrieved from the theft / recovery server may indicate that the current device state (e.g., the device state of the previous device state update retrieved from the theft / recovery server) is a "normal" device state (e.g., the device state of the user device has been changed from a "disabled" device state or an "erased and disabled" device state to a "normal" device state). As shown by reference numeral 348, in conjunction with the determination that the updated device state of the user device is the "normal" device state, the user device may enable communication capabilities of the user device. For example, the user device may enable a SIM interface (e.g., a SIM card slot), Wi-Fi, GNSS, Bluetooth, and / or a peripheral connection (e.g., a USB port). In some aspects, the theft / recovery module may instruct the UIM of the modem to enable communication capabilities (e.g., a SIM interface, Wi-Fi, GNSS, Bluetooth, and / or a peripheral connection), and the communication capabilities module may enable the communication capabilities (e.g., a SIM interface, Wi-Fi, GNSS, Bluetooth, and / or a peripheral connection). In some aspects, the user device may also enable activation (and / or deactivation) of communication capabilities (such as SIM interface, Wi-Fi, GNSS, and / or Bluetooth) via one or more applications executing on the user device.
