## Title
User equipment detection of interference-sensitive devices

## Abstract

Concepts and technologies are described herein for user equipment (“UE”) detection of interference-sensitive devices. According to one aspect disclosed herein, a mobile initiator device can utilize a near-field communications (“NFC”) hardware component to generate a radio frequency (“RF”) field that is used to activate a passive NFC component associated with an interference-sensitive device. The mobile initiator device can utilize the NFC hardware component to receive information about an interference sensitivity of the interference-sensitive device. The mobile initiator device can adjust one or more operational aspects of the mobile initiator device to accommodate the interference sensitivity information of the interference-sensitive device.

## Background
BACKGROUND
Near-field communications (“NFC”) is a short-range wireless technology that allows detection and communication between powered active “initiator” devices and non-powered passive “target” devices. A passive target device is typically a very small sticker with no connected power source. Passive target devices receive power from a radio frequency (“RF”) field from an initiator device. Upon receipt of an RF field, the passive target device establishes a transponder relationship with the initiator device, and the passive target device can transmit information to the initiator device.
Wireless voice and data services are expanding beyond the limits of available dedicated cellular spectrum. Clearing new dedicated spectrum for cellular use is complex and expensive, especially in cases where legacy, interference-sensitive devices and services already occupy the spectrum or are sensitive to transmissions from such spectrum. A particularly challenging interference sensitivity case occurs between mobile devices, such as cellular telephones, that operate in proximity to pacemakers and other medical devices, high definition televisions and other consumer electronics, and global positioning sensor (“GPS”) receivers. In this case, regulators should plan and fund the replacement of these legacy devices before selling spectrum or find spectrum buyers that are willing to wait years to put purchased spectrum to use. These cases limit regulator opportunity to sell spectrum (filling government coffers) and they limit cellular operator and device vendor access to much needed spectrum to meet subscriber demands. In order to support such dramatic growth, cellular operators, device vendors and regulators are now looking beyond traditional dedicated spectrum options. Shared spectrum use has some cost and resource efficiency advantages, especially in cases where demand is temporary and dynamic. Where demand is temporary, it is sometimes advantageous to use spectrum on a temporary basis rather than making a permanent investment in such spectrum. Unfortunately this shared spectrum option has similar technical challenges as dedicated spectrum clearing—that is, there is currently no practical and cost-effective means to identify and protect interference-sensitive devices from nearby cellular transmissions without replacement.
SUMMARY
Concepts and technologies are described herein for user equipment (“UE”) detection of interference-sensitive devices. According to one aspect disclosed herein, a mobile initiator device can utilize a near-field communications (“NFC”) hardware component to generate a radio frequency (“RF”) field that is used to activate a passive NFC component associated with an interference-sensitive device. The mobile initiator device can utilize the NFC hardware component to receive information about an interference sensitivity of the interference-sensitive device. The mobile initiator device can adjust one or more operational aspects of the mobile initiator device to accommodate the interference sensitivity information of the interference-sensitive device.
In some embodiments, the mobile initiator device can monitor a mobility state of the mobile initiator device. In these embodiments, the mobile initiator device can generate the RF field in response to a change in the mobility state.
In some embodiments, the information about the interference sensitivity includes at least one of a device type, a radio type, a receive sensitivity frequency band, a transmit sensitivity frequency band, a receive filter sensitivity, a transmit filter sensitivity, a receive in-band noise rise limit, a receive in-band receiver overload limit, or a transmit power range.
In some embodiments, the operational aspect of the mobile initiator device includes an adjustment to a transmit power of the mobile initiator device. In some embodiments, the operational aspect of the mobile initiator device includes an adjustment to a frequency upon which the mobile initiator device transmits. In some embodiments, the operational aspect of the mobile initiator device includes an adjustment to a duplexing type utilized by the mobile initiator device.
In some embodiments, the mobile initiator device, in response to receiving the information about the interference sensitivity of the interference-sensitive device, can generate a confirmation message to confirm receipt of the information about the sensitivity of the interference-sensitive device and can send the confirmation message to the interference-sensitive device.
According to another aspect disclosed herein, an interference-sensitive device can activate a passive near-field communications component in response to an RF field generated by a mobile initiator device. The interference-sensitive device can provide information about one or more interference sensitivities to the mobile initiator device.

Referring now to the drawings, in which like numerals represent like elements throughout the several figures, example aspects of traffic steering across radio access technologies and radio frequencies utilizing cell broadcast messages will be presented.
Referring now to FIG. 1, aspects of an illustrative operating environment 100 for various concepts disclosed herein will be described. It should be understood that the operating environment 100 and the various components thereof have been greatly simplified for purposes of discussion. Accordingly, additional or alternative components of the operating environment 100 can be made available without departing from the embodiments described herein.
The illustrated operating environment 100 includes a user 102 who is associated with a mobile initiator device 104. The mobile initiator device 104 can be a cellular telephone, a feature phone, a smartphone, a mobile computing device, a portable television, a portable video game console, other computing device, or other user equipment (“UE”). The mobile initiator device 104 can establish a connection 106, via near-field communications (“NFC”), with one or more passive target devices, such as an interference-sensitive device 108, in response to the target device(s) receiving power from a radio frequency (“RF”) field 110 generated by the mobile initiator device 104. The interference-sensitive device 108 can include any device that is sensitive to RF interference, some examples of which include, but are not limited to, medical devices such as pacemakers and consumer electronics such as high definition televisions, WI-FI routers, cordless phones, and baby monitors. Upon receipt of the RF field 110, the target device(s) can each establish a transponder relationship with the mobile initiator device 104, and the target device(s) can exchange information with the mobile initiator device 104 via the connection 106.
In the illustrated example, the interference-sensitive device 108 can detect, via a passive NFC component 112, the RF field 110, to establish a transponder relationship with the mobile initiator device 104, and to provide interference-sensitive device interference sensitivity information 114 (hereinafter “ISD interference sensitivity information 114”) to the mobile initiator device 104. The ISD interference sensitivity information 114 can include any information regarding one or more operational aspects of the interference-sensitive device 108 that is/are sensitive to RF interference. By way of example, the ISD interference sensitivity information 114 can include a device type (e.g., a consumer electronics device, medical device, public safety device, or military device), a radio type (e.g., receive-only, transmit-only, or receive and transmit), one or more receive sensitive frequency bands (e.g., including a start frequency and a stop frequency), a receive filter selectivity (“Qrx”), a transmit filter selectivity (“Qtx”), a receive in-band noise rise limit, a receive in-band receiver overload limit, one or more transmit sensitive frequency bands (e.g., including a start frequency and a stop frequency) a transmit power range, or some combination thereof.
The mobile initiator device 104 can adjust one or more operational aspects of the mobile initiator device 104 to accommodate one or more interference sensitivities of the interference-sensitive device 108 as specified in the ISD interference sensitivity information 114. The operational aspects of the mobile initiator device 104 can include any operational aspect of the mobile initiator device 104 that might interfere with one or more operational aspects of the interference-sensitive device 108. Some examples of operational aspects of the mobile initiator device 104 include, but are not limited to, a transmit power, a frequency upon which the mobile initiator device 104 transmits, a duplexing type utilized by the mobile initiator device 104, a communications type (e.g., cellular, WI-FI, BLUETOOTH), and/or the like.)
The illustrated mobile initiator device 104 includes a mobile initiator device processor 116 (hereinafter “MID processor 116”), a mobile initiator device memory 118 (hereinafter “MID memory 118”), one or more operating systems 120, one or more applications 122, an NFC RF field module 124, a mobility state determination module 126, one or more NFC hardware components 128, one or more mobility state determination hardware components 130, mobile initiator device interference sensitivity information 132 (hereinafter “MID sensitivity information 132”), and one or more radio access components 134.
The MID processor 116 can include one or more processing units configured to process data, execute computer-executable instructions of one or more application programs such as the application(s) 122, which can be stored in the MID memory 118, and communicate with other components of the mobile initiator device 104 in order to perform various operations described herein, such as the operations illustrated and described herein with reference to FIGS. 2 and 3. The MID processor 116 may be a standard central processor that performs arithmetic and logical operations, a more specific purpose programmable logic controller (“PLC”), a programmable gate array, a system-on-a-chip, or other type of processor known to those skilled in the art and suitable for controlling the operation of the server computer. Processing units are generally known, and therefore the functionality of processing units is not described in further detail herein.
The MID memory 118 can include, but is not limited to, processor registers, processor cache, random access memory (“RAM”), other volatile and non-volatile memory devices, semi-permanent or permanent memory types; for example, tape-based media, optical media, flash media, hard disks, combinations thereof, and the like. While the MID memory 118 is illustrated as residing proximate to the MID processor 116, it should be understood that the MID memory 118 may be a remotely accessed storage system, for example, a server and/or database on a communications network, a remote hard disk drive, a removable storage medium, a database, a server, an optical media writer, combinations thereof, or the like. Memory units are generally known, and therefore the functionality of memory units is not described in further detail herein.
In the claims, the phrase “computer storage medium” and variations thereof is intended to encompass devices such as the MID memory 118 and other memory components disclosed herein and does not include waves or signals per se and/or communication media such as computer-readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any delivery media.
The operating system(s) 120 can include one or more programs for controlling the operation of the mobile initiator device 104. The operating system(s) 120 can include a member of the SYMBIAN OS family of operating systems from SYMBIAN LIMITED, a member of the WINDOWS MOBILE OS and/or WINDOWS PHONE OS families of operating systems from MICROSOFT CORPORATION, a member of the PALM WEBOS family of operating systems from HEWLETT PACKARD CORPORATION, a member of the BLACKBERRY OS family of operating systems from RESEARCH IN MOTION LIMITED, a member of the IOS family of operating systems from APPLE INC., a member of the ANDROID OS family of operating systems from GOOGLE INC., and/or other operating systems. These operating systems are merely illustrative of some contemplated operating systems that may be used in accordance with various embodiments of the concepts and technologies described herein and therefore should not be construed as being limiting in any way.
The application(s) 122 can execute on top of the operating system(s) 120. The application(s) 122 can include, for example, one or more presence applications, one or more visual voice mail applications, one or more messaging applications, one or more text-to-speech and/or speech-to-text applications, one or more add-ons, one or more plug-ins, one or more email applications, one or more music applications, one or more video applications, one or more camera applications, one or more location-based service applications, one or more power conservation applications, one or more game applications, one or more productivity applications, one or more entertainment applications, one or more enterprise applications, combinations thereof, and the like.
The NFC RF field module 124 can include computer-readable instructions that can be executed by one or more of the NFC hardware component(s) 128 (e.g., a microcontroller) and/or can be executed by one or more processors, such as the MID processor 116, to cause the NFC hardware component(s) 128 to activate and deactivate the RF field 110 according to duty cycle criteria, which can include an absolute mobility state of the mobile initiator device 104, a mobility state change, and/or a cell visitation history as will be described in greater detail below. The NFC RF field module 124 can be embedded in the NFC hardware component(s) 128 and/or can be stored in a memory, such as the MID memory 118, and made accessible to the NFC hardware component(s) 128.
The NFC RF field module 124 can cause the NFC hardware component(s) 128 to automatically activate the RF field 110 when NFC detection and data exchange are likely to be utilized. The NFC RF field module 124 also can cause the NFC hardware component(s) 128 to automatically deactivate the RF field 110 for battery conservation when NFC detection and data exchange are less likely to be utilized. The determination of whether or not NFC should be utilized can be based upon the absolute mobility state of the mobile initiator device 104, changes in the mobility state, and/or cell visitation history. Whether or not NFC detection and data exchange should be utilized is rarely 100% predictable. For this reason, the RF field 110 can be cycled on and off according to a battery-efficient duty cycle (also referred to herein as a “gating pattern”). The gating pattern can provide a balance between detection success and battery efficiency.
NFC communications are low-powered and typically only useful within a relatively short range (e.g., few feet) between the initiator and target devices—the mobile initiator device 104 and the interference-sensitive device 108, respectively, in the illustrated example. NFC communications between mobile initiator and target devices are therefore unreliable or relatively short-lived if relative mobility speed is high. Battery-powered NFC communications are therefore useful only when the mobile initiator and target devices are relatively stationary. For this reason, a highly mobile initiator device (e.g., the user 102 driving or riding in a vehicle with the mobile initiator device 104—hereinafter “vehicular mobility state”) can conserve battery by activating the RF field 110 infrequently and for a relatively short hold time. The probability of useful NFC communication is higher if the user 102 is walking with the mobile initiator device 104 (hereinafter “pedestrian mobility state”). In the pedestrian mobility state, the RF field 110 should be active most of the time in order for the mobile initiator device 104 to detect and communicate with nearby target devices such as the interference-sensitive device 108. If the mobility state is “stationary” (e.g., the user 102 has placed the mobile initiator device 104 on a desk or other surface or the mobile initiator device 104 is in a pocket while the user 102 is seated), then the likelihood of new NFC target devices is low. In this case, the stationary initiator device can conserve battery by activating the RF field 110 infrequently and for a relatively short hold time. In these examples, the RF field duty cycles can be adapted as follows:
Vehicular=driving: Low RF field duty cycle=high battery efficiency;
Pedestrian=walking: High RF field duty cycle=high detection success;
Stationary=sitting: Low RF field duty cycle=high battery efficiency.
The mobility state—vehicular, pedestrian, or stationary, for example—can be determined by the mobile initiator device 104 via execution, via one or more processors, of instructions included in the mobility state determination module 126 based upon output provided by the mobility state determination hardware component(s) 130. The mobility state determination module 126 can be programmed to define the RF field duty cycles for one or more mobility states. The mobility state determination module 126 can receive output from the mobility state determination hardware component(s) 130 and can determine, based at least in part upon the output, the RF field duty cycle to employ for the mobility state associated with the received output.
The mobility state determination module 126 also can detect changes in the mobility state of the mobile initiator device 104. In response to detecting a change, the mobility state determination module 126 can instruct the NFC RF field module 124 to cause the NFC hardware component(s) 128 to activate the RF field 110 for a specified time to detect nearby NFC target devices, such as the interference-sensitive device 108.
The NFC hardware component(s) 128 can include one or more devices that support NFC-compatible air-interface protocols, standards, and specifications. For example, the NFC hardware component(s) 128 can include one or more transceiver devices each capable of generating the RF field 110 at a designated operating frequency, such as 13.56 megahertz (“MHz”). The NFC hardware component(s) 128 also can include one or more antennas, one or more microcontrollers, one or more memory components, and/or the like. Moreover, the NFC hardware component(s) 128 can be built-in to the mobile initiator device 104 and/or in communication with the mobile initiator device 104 via BLUETOOTH, other RF, a wired connection, and/or the like as an add-on component to the mobile initiator device 104.
The mobile initiator device interference sensitivity information 132 (hereinafter “MID interference sensitivity information 132”) can include any information regarding one or more operational aspects of the mobile initiator device 104 that is/are sensitive to RF interference. By way of example, the MID interference sensitivity information 132 can include a radio type (e.g., receive-only, transmit-only, or receive and transmit), one or more receive sensitive frequency bands (e.g., including a start frequency and a stop frequency), a receive filter selectivity (“Qrx”), a transmit filter selectivity (“Qtx”), a receive in-band noise rise limit, a receive in-band receiver overload limit, one or more transmit sensitive frequency bands (e.g., including a start frequency and a stop frequency) a transmit power range, or some combination thereof.
The mobile initiator device 104 is configured to connect to and communicate, via one or more of the radio access components 134, with a network 136 for voice and/or data communications between the mobile initiator device 104 and one or more other mobile devices, computers, servers, networking devices, and/or other networks (not shown). The network 136 may operate in accordance with one or more mobile telecommunications standards including, but not limited to, Global System for Mobile communications (“GSM”), Code Division Multiple Access (“CDMA”) ONE, CDMA2000, Universal Mobile Telecommunications System (“UMTS”), Long-Term Evolution (“LTE”), Worldwide Interoperability for Microwave Access (“WiMAX”), other 802.XX technologies, and/or the like. The network 136 can include one or more radio access networks (“RANs”). A RAN can utilize various channel access methods (which may or may not be used by the aforementioned standards) including, but not limited to, Time Division Multiple Access (“TDMA”), Frequency Division Multiple Access (“FDMA”), Single Carrier FDMA (“SC-FDMA”), CDMA, wideband CDMA (“W-CDMA”), Orthogonal Frequency Division Multiplexing (“OFDM”), Space Division Multiple Access (“SDMA”), and/or the like to provide a radio/air interface to the mobile initiator device 104. Data communications can be provided in part by a RAN using General Packet Radio Service (“GPRS”), Enhanced Data rates for Global Evolution (“EDGE”), the High-Speed Packet Access (“HSPA”) protocol family including High-Speed Downlink Packet Access (“HSDPA”), Enhanced Uplink (“EUL”) or otherwise termed High-Speed Uplink Packet Access (“HSUPA”), Evolved HSPA (“HSPA+”), LTE, and/or various other current and future wireless data access technologies. Moreover, a RAN may be a GSM RAN (“GRAN”), a GSM EDGE RAN (“GERAN”), a UMTS Terrestrial Radio Access Network (“UTRAN”), an E-UTRAN, any combination thereof, and/or the like.
The network 136 can include a wireless wide area network (“WWAN”), which may, in turn, include one or more core networks such as a circuit-switched core network (“CS CN”), a packet-switched core network (“PS CN”), and/or an IP multimedia subsystem (“IMS”) core network. The WWAN can utilize one or more mobile telecommunications technologies, such as those described above, to provide voice and/or data services via one or more RANs to one or more radio components of one or more mobile devices, such as the radio access component(s) 134 of mobile initiator device 104. Moreover, a mobile telecommunications network can provide a connection to an internet or other WAN so that the mobile initiator device 104 can access internet content such as websites, streaming media, online video games, downloadable content, and the like.
A RAN operating within or as part of the network 136 can include one or more cells. As used herein, a “cell” refers to a geographical area that is served by one or more base stations operating within a RAN. As used herein, a “base station” refers to a radio receiver and/or transmitter (collectively, transceiver) that is/are configured to provide a radio/air interface by which one or more mobile devices, such as the mobile initiator device 104, can connect to the network 136. Accordingly, a base station is intended to encompass one or more base transceiver stations (“BTSs”), one or more Node Bs, one or more eNodeBs, and/or other networking nodes that are capable of providing a radio/air interface regardless of the technologies utilized to do so. A base station can be in communication with one or more antennas (not shown), each of which may be configured in accordance with any antenna design specifications to provide a physical interface for receiving and transmitting radio waves to/from the network 136.
The mobile initiator device 104 can camp on and monitor cellular sites while in an idle mode, thus allowing call setup and incoming call page detection. Each cell site sector carrier has a unique identifier referred to herein as a physical cell identifier (“PCI”), which is broadcast by the cell site and detected by the mobile initiator device 104 while in active or idle mode within the associated service area. When the mobile initiator device 104 activates the RF field 110, the mobile initiator device 104 may or may not receive a response from nearby NFC devices, such as the interference-sensitive device 108. Each time the mobile initiator device 104 does receive a response from one or more nearby NFC target devices, the mobile initiator device 104 can record the pertinent PCI of the camping cell site in the MID memory 118. Over time, a cell visitation history can be built. The cell visitation history can include which PCIs do and do not have one or more overlaid NFC devices. The cell visitation history can be used to further optimize the RF field activation. For example, the mobile initiator device 104 can use a higher RF field duty cycle and improve detection probability and time when camping on cells with a history of NFC device detection. The mobile initiator device 104 can reduce RF field duty cycle and conserve battery when camping on cells with no history of NFC device detection.
The illustrated interference-sensitive device 108 also includes an interference-sensitive device processor (hereinafter “ISD processor 138”) and an interference-sensitive device memory (hereinafter “ISD memory 140”). The ISD processor 138 can include one or more processing units configured to process data, execute computer-executable instructions of one or more application programs (not shown), which can be stored in the ISD memory 140, and communicate with other components of the interference-sensitive device 108 in order to perform various operations described herein, such as the operations illustrated and described herein with reference to FIGS. 4 and 5. The ISD processor 138 may be a standard central processor that performs arithmetic and logical operations, a more specific purpose PLC, a programmable gate array, a system-on-a-chip, or other type of processor known to those skilled in the art and suitable for controlling the operation of the server computer. Processing units are generally known, and therefore the functionality of processing units is not described in further detail herein.
The ISD memory 140 can include, but is not limited to, processor registers, processor cache, RAM, other volatile and non-volatile memory devices, semi-permanent or permanent memory types; for example, tape-based media, optical media, flash media, hard disks, combinations thereof, and the like. While the ISD memory 140 is illustrated as residing proximate to the ISD processor 138, it should be understood that the ISD memory 140 may be a remotely accessed storage system, for example, a server and/or database on a communications network, a remote hard disk drive, a removable storage medium, a database, a server, an optical media writer, combinations thereof, or the like. Memory units are generally known, and therefore the functionality of memory units is not described in further detail herein.
Turning now to FIG. 2, a flow diagram illustrating aspects of a method 200 for UE detection of one or more interference-sensitive devices, such as the interference-sensitive device 108, from the perspective of a UE device, such as the mobile initiator device 104, will be described, according to an illustrative embodiment. It should be understood that the operations of the illustrative methods disclosed herein are not necessarily presented in any particular order and that performance of some or all of the operations in an alternative order(s) is possible and is contemplated. The operations have been presented in the demonstrated order for ease of description and illustration. Operations may be combined, separated, added, omitted, modified, and/or performed simultaneously or in another order without departing from the scope of the subject disclosure.
It also should be understood that the illustrated methods can be ended at any time and need not be performed in their entirety. Some or all operations of the methods, and/or substantially equivalent operations, can be performed by execution of computer-executable instructions included on a computer-readable storage media, as defined below. The term “computer-executable instructions,” and variants thereof, as used in the description and claims, is used expansively herein to include routines, application programs, software, application modules, program modules, components, data structures, algorithms, and the like. Computer-executable instructions can be implemented on various system configurations, including single-processor or multiprocessor systems, distributed computing systems, minicomputers, mainframe computers, personal computers, hand-held computing devices, microprocessor-based, programmable consumer electronics, combinations thereof, and the like.
Thus, it should be appreciated that the logical operations described herein may be implemented (1) as a sequence of computer implemented acts or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system. The implementation is a matter of choice dependent on the performance and other requirements of the computing system. Accordingly, the logical operations described herein are referred to variously as states, operations, structural devices, acts, or modules. These operations, structural devices, acts, and modules may be implemented in software, in firmware, in special purpose digital logic, and any combination thereof.
The method 200 is described from the perspective of the mobile initiator device 104. The method 200 begins and proceeds to operation 202, where the mobile initiator device 104 monitors a mobility state of the mobile initiator device 104. From operation 202, the method 200 proceeds to operation 204, where the mobile initiator device 104 determines whether the mobility state has changed. If the mobility state has not changed, the method 200 returns to operation 202, where the mobile initiator device 104 continued to monitor the mobility state. If, however, the mobility state has changed, the method 200 proceeds from operation 204 to operation 206. At operation 206, the mobile initiator device 104 generates an RF field, such as the RF field 110 (shown in FIG. 1). The RF field 110 is used to activate one or more passive NFC components associated with one or more interference-sensitive devices, such as the passive NFC component 112 of the interference-sensitive device 108.
From operation 206, the method 200 proceeds to operation 208, where the mobile initiator device 104 receives information about one or more interference sensitivities of the interference-sensitive device 108, such as the ISD interference sensitivity information 114. By way of example, the ISD interference sensitivity information 114 can include a device type (e.g., a consumer electronics device, medical device, public safety device, or military device), a radio type (e.g., receive-only, transmit-only, or receive and transmit), one or more receive sensitive frequency bands (e.g., including a start frequency and a stop frequency), a receive filter selectivity (“Qrx”), a transmit filter selectivity (“Qtx”), a receive in-band noise rise limit, a receive in-band receiver overload limit, one or more transmit sensitive frequency bands (e.g., including a start frequency and a stop frequency) a transmit power range, or some combination thereof.
From operation 208, the method 200 proceeds to operation 210, where the mobile initiator device 104 adjusts one or more operational aspects of the mobile initiator device 104 to accommodate the one or more interference sensitivities specified in the ISD interference sensitivity information 114. The operational aspects of the mobile initiator device 104 can include any operational aspect of the mobile initiator device 104 that might interfere with one or more operational aspects of the interference-sensitive device 108. Some examples of operational aspects of the mobile initiator device 104 include, but are not limited to, a transmit power, a frequency upon which the mobile initiator device 104 transmits, a duplexing type utilized by the mobile initiator device 104, a communications type (e.g., cellular, WI-FI, BLUETOOTH, and/or the like).
From operation 210, the method 200 proceeds to operation 212, where the mobile initiator device 104 generates a confirmation message and sends the confirmation message to the interference-sensitive device to confirm receipt of the ISD interference sensitivity information 114. From operation 212, the method 200 proceeds to operation 214. The method 200 ends at operation 214.
Turning now to FIG. 3, a flow diagram illustrating aspects of a method for UE detection of interference-sensitive devices from the perspective of an interference-sensitive device, such as the interference-sensitive device 108, will be described, according to an illustrative embodiment. The method 300 begins and proceeds to operation 302, where the interference-sensitive device 108 detects an RF field, such as the RF field 110, generated by a UE, such as the mobile initiator device 104. From operation 302, the method 300 proceeds to operation 304, where the interference-sensitive device 108 activates the passive NFC component 112 in response to the RF field 110.
From operation 304, the method 300 proceeds to operation 306, where the interference-sensitive device 108 collects sensitivity information, such as the ISD interference sensitivity information 114.
