The present disclosure relates to electronic communication, and more particularly, to a system to allow a non-network controller device to respond to out-of-network communications.
Wireless communication has moved beyond simple cellular-based voice communication and is now being used for a variety of data-related tasks. For example, devices may utilize long-range wireless mediums such as cellular communications for various applications. However, in some instances wireless interaction may occur via a short-range wireless medium (e.g., within a range of about 65 feet) or a close-proximity wireless medium (e.g., within inches). Short-range and close-proximity wireless mediums such as, for example, Wireless Local Area Networking (WLAN), Bluetooth, radio frequency (RF) such as based on RF Identification (RFID) or Near Field Communication (NFC) standards, infrared (IR), etc. have advantages over long-range wireless communication in that they facilitate wireless interaction in “unregulated” frequency spectrum, and thus are free to operate without having to license the spectrum. As a result, the utilization of short-range and close-proximity wireless communication is continuing to expand.
At least one issue with the use of some short-range wireless communication mediums is the need for a wireless network control entity. For example, WLAN or “Wi-Fi” operating in accordance with the IEEE 802.11 wireless standard is designed to employ an access point (AP) to manage wireless traffic in the network. An AP is not required in Bluetooth networks, which was initially designed as a wireless replacement for wired peripheral connections. The desire for device-to-device (D2D) wireless connectivity, such as provided by Bluetooth, with the stability, throughput, security, equipment availability, etc. of Wi-Fi has yielded “Wi-Fi Direct” or “Wi-Fi Peer-to-Peer (P2P).” Wi-Fi Direct allows Wi-Fi-enabled devices to interact directly without the need for specialized equipment such as a Bluetooth transceiver. While the benefits of Wi-Fi Direct may be apparent, at least one drawback of interaction based on the Wi-Fi Direct Technical Specification as defined by the Wi-Fi Alliance (http://www.wi-fi.org/discover-wi-fi/wi-fi-direct) is the requirement for a device in the network to act as a group owner (GO) to manage wireless interaction within the group. As opposed to a dedicated AP, it may be possible for a GO to become “busy” to a degree that it cannot perform network-related activities such as, for example, responding to inquiries from devices outside the network regarding devices within the network.
Features and advantages of various embodiments of the claimed subject matter will become apparent as the following Detailed Description proceeds, and upon reference to the Drawings, wherein like numerals designate like parts, and in which:
Although the following Detailed Description will proceed with reference being made to illustrative embodiments, many alternatives, modifications and variations thereof will be apparent to those skilled in the art.
The present disclosure is directed to a system for non-network controller communication. In general, an example wireless network may comprise a network controller (NC) device and at least one network member (NM) device. The at least one NM device may respond to inquiries received from outside-of-network (OoN) devices by providing at least an NC device name in a user-friendly form. This information may be provided via a new information element (IE) that is described herein. Should the at least one NC device later receive a service discovery request (e.g., from the OoN device), the at least one NC device may determine whether services it may provide are currently unavailable, and may then transmit a service discovery response including at least unavailable service information. In at least one embodiment, service discovery responses may also include information about current consumers of the unavailable services. The OoN device may then generate a notification to the user based on the unavailable service information.
In at least one embodiment, an example device operable within a wireless network may comprise communication circuitry and service management circuitry. The communication circuitry may be to interact via at least wireless communication. The service management circuitry may be to receive a probe request via the communication circuitry and transmit at least a probe request response via the communication circuitry, the probe request response including at least information identifying a NC device for a wireless network including the device.
In at least one embodiment, the communication circuitry may further be to perform at least one wireless connection establishment operation to connect to at least the NC device in the wireless network. The information identifying the NC device may comprise, for example, at least a user-friendly name for the network controller device. The wireless network may be based on the IEEE 802.11 standard. In this case, the probe request response may comprise at least a service set identifier and a basic service set identifier for the wireless network.
In at least one embodiment, the service management circuitry may also be to receive a service discovery request via the communication circuitry, determine services that are unavailable in the device and transmit a service discovery response via the communication circuitry, the service discovery response including at least information indicating services that are unavailable in the device. The information indicating services that are unavailable in the device may also include data about current consumers of the unavailable services.
Consistent with the present disclosure, a wireless device may comprise, for example, communication circuitry to interact via at least wireless communication and processing circuitry to transmit a probe request via the communication circuitry, receive a probe response request via the communication circuitry, the probe response request identifying a non-network controller device in a wireless network, transmit a service discovery request to at least the non-network controller device via the communication circuitry and receive a service discovery response via the communication circuitry, the service discovery response including at least information indicating services that are unavailable in the non-network controller device. The wireless device may further comprise user interface circuitry to generate at least one notification based on the services that are unavailable in the non-network controller device. The information indicating the services that are unavailable in the device may also include data about current consumers of the unavailable services. The at least one notification may also be based on the current consumers of the unavailable services. Consistent with the present disclosure, an example method for non-network controller communication may comprise receiving a probe request via wireless communication at a device in a wireless network managed by a network controller device and transmitting at least a probe request response including at least information identifying the network controller device for the wireless network.
Example system 100 may comprise at least wireless network 102 and at least one OoN device 104. Wireless network 102 may be formed between NC device 106 and at least one NM device 108A, device 108B . . . device 108n (collectively, NM devices 108A . . . n). In general, OoN device 104, NC device 106 and NM devices 108A . . . n may comprise resources configurable to at least process information and interact via wireless communication. Examples of these devices may include, but are not limited to, a mobile communication device such as a cellular handset or a smartphone based on the Android® OS from the Google Corporation, iOS® or Mac OS® from the Apple Corporation, Windows® OS from the Microsoft Corporation, Tizen® OS from the Linux Foundation, Firefox® OS from the Mozilla Project, Blackberry® OS from the Blackberry Corporation, Palm® OS from the Hewlett-Packard Corporation, Symbian® OS from the Symbian Foundation, etc., a mobile computing device such as a tablet computer like an iPad® from the Apple Corporation, Surface® from the Microsoft Corporation, Galaxy Tab® from the Samsung Corporation, Kindle® from the Amazon Corporation, etc., an Ultrabook® including a low-power chipset from the Intel Corporation, a netbook, a notebook, a laptop, a palmtop, etc., a wearable device such as a wristwatch form factor computing device like the Galaxy Gear® from Samsung, an eyewear form factor computing device/user interface like Google Glass® from the Google Corporation, a virtual reality (VR) headset device like the Gear VR® from the Samsung Corporation, the Oculus Rift® from the Oculus VR Corporation, etc., a typically stationary computing device such as a desktop computer, a server, a group of computing devices organized in a high performance computing (HPC) architecture, a smart television or other type of “smart” device, small form factor computing solutions (e.g., for space-limited applications, TV set-top boxes, etc.) like the Next Unit of Computing (NUC) platform from the Intel Corporation, etc.
Consistent with the present disclosure, wireless network 102 may be formed utilizing Wi-Fi direct or another similar short-range wireless networking technology. Using Wi-Fi direct as an example, connection establishment operations may occur between devices that form wireless network 102. During connection establishment, NC device 106 may be configured to manage the operation of wireless network 102 in a role similar to that of an AP operating in a standard IEEE 802.11 (WLAN) network. At least one other NM device 108A . . . n may form the network with NC device 106 and remain linked to NC device 106 (e.g., via a lower power mode) to, for example, keep timing with wireless network 102, receive commands from NC device 106, etc.
In typical operation, devices may join wireless network 102 to access resources residing in another networked device. For example, NC device 106 may be a smart phone comprising at least multimedia data, and NM device 108A may be capable of presenting multimedia data (e.g., generating sound based on audio content, displaying images/video based on visual content, etc.). NC device 106 may access presentation resources on NM device 108A to present the multimedia content. During this interaction, other NM devices 108B . . . n may be unable to access at least the multimedia playback resources of NM device 108A. For example, given that NM device 108A is a television, monitor, projector, etc. to which NC device 106 is sending video for presentation, NM device 108A would not be able to present other multimedia data while playing the video. The above scenario is merely an example of a single-user service that may be available within network 102. Other scenarios may exist where resources in a device, or the device itself, may only be accessible to other devices one-at-a-time due to the nature of the services they provide (e.g., mobile device docking station, remote control functionality, certain types of printers, etc.).
OoN device 104 may seek to access resources within network 120. In typical operation, OoN device 104 may interact with NC device 106 to join the network, learn what functionality is available from NM devices 108A . . . n, etc. However, NC device 106 is not a dedicated AP, and may at times be unable to respond to OoN device 104. For example, NC device 106 may access a resource in NM device 108A and during the access may be unable to respond to other devices. Consistent with the present disclosure, NM devices 108A . . . n may be able to respond directly to an inquiry from OoN device 104, and in this response may inform OoN device 104 of at least services that are currently unavailable due to, for example, the services already being accessed by other devices in wireless network 102. In an example of operation, OoN device 104 may initially transmit an inquiry to all devices in wireless network 102 as shown at 110. NC device 106 and NM devices 108A . . . n may receive the inquiry. NC device 106 would normally respond to inquiry 110, however, as shown at 112 in this example NC device 106 is not able to respond. The inability of NC device 106 to respond is alleviated by NM devices 108A . . . n responding to inquiry 110 directly as shown at 114. In this manner, OoN device 104 may still learn the status of services in NM devices 108A . . . n without having to wait for NC device 106 to respond.
In at least one embodiment, non-controller response 114 may include at least two phases. Initially, non-controller response 114 may provide to OoN device 104 a user-friendly name of NC device 106 (e.g., “My device,” “Jim's phone”, “ABC Company Device #3,” etc.) along with information usable to connect to wireless network 102. The receipt of this initial response may, for example, allow OoN device 104 to inform a user that OoN device 104 is receiving a response from an NM device 108A . . . n in wireless network 102, and may further automatically, or upon user action, cause OoN device 104 to send another message inquiring about services available from NM devices 108A . . . n. Each NM device 108A . . . n may respond to the further inquiry by providing at least information about currently unavailable services. OoN device 104 may use at least the received unavailable service information to generate a user notification. An example user notification may include presenting information on a display in OoN device 104 identifying NM devices 108A . . . n from which responses were received. Selecting one of the displayed NM devices 108A . . . n may cause OoN device 104 to present at least the unavailable services for the selected NM device 108A . . . n. When the response from NM devices 108A . . . n comprises “full” service information (e.g., including both available an unavailable services), OoN device 104 may present a list of all services in the particular NM device 108A . . . n along with indicia indicating the particular services that are currently unavailable. In at least one embodiment, the unavailable service information may also identify current consumers of unavailable services. A “consumer” of a service may be a device or user that is currently utilizing the service. Continuing with the explanatory example set forth above, NM device 108A may transmit a response to OoN device 104 indicating that NC device 106 is currently utilizing multimedia playback services on NM device 108A. This information may be presented to the user of OoN device 104. Knowing the consumer of an unavailable service may allow for corrective action. For example, the user of OoN device 104 may manually halt video playback on NM device 108A, may confirm with the user of NC device 106 that is it OK to halt video playback, etc. When the situation is rectified, OoN device 104 may join wireless network 102 and access resources in NM devices 108A . . . n.
NM device 108A′ may comprise, for example, system circuitry 200 to manage operation of the device. System circuitry 200 may include, for example, processing circuitry 202, memory circuitry 204, power circuitry 206, user interface circuitry 208 and communication interface circuitry 210. NM device 108A′ may further include communication circuitry 212 and service management circuitry 214. While communication circuitry 210 and service management circuitry 214 are illustrated as separate from system circuitry 200, the example configuration shown in
In NM device 108A′, processing circuitry 202 may comprise one or more processors situated in separate components, or alternatively one or more processing cores in a single component (e.g., in a system-on-chip (SoC) configuration), along with processor-related support circuitry (e.g., bridging interfaces, etc.). Example processors may include, but are not limited to, various x86-based microprocessors available from the Intel Corporation including those in the Pentium, Xeon, Itanium, Celeron, Atom, Quark, Core i-series, Core M-series product families, Advanced RISC (e.g., Reduced Instruction Set Computing) Machine or “ARM” processors, etc. Examples of support circuitry may include chipsets (e.g., Northbridge, Southbridge, etc. available from the Intel Corporation) configured to provide an interface through which processing circuitry 202 may interact with other system components that may be operating at different speeds, on different buses, etc. in NM device 108A′.

Processing circuitry 202 may be configured to execute various instructions in NM device 108A′. Instructions may include program code configured to cause processing circuitry 202 to perform activities related to reading data, writing data, processing data, formulating data, converting data, transforming data, etc. Information (e.g., instructions, data, etc.) may be stored in memory circuitry 204. Memory circuitry 204 may comprise random access memory (RAM) and/or read-only memory (ROM) in a fixed or removable format. RAM may include volatile memory configured to hold information during the operation of NM device 108A′ such as, for example, static RAM (SRAM) or dynamic RAM (DRAM). ROM may include non-volatile (NV) memory circuitry configured based on BIOS, UEFI, etc. to provide instructions when NM device 108A′ is activated, programmable memories such as electronic programmable ROMs (EPROMS), Flash, etc. Other fixed/removable memory may include, but are not limited to, magnetic memories such as, for example, floppy disks, hard drives, etc., electronic memories such as solid state flash memory (e.g., embedded multimedia card (eMMC), etc.), removable memory cards or sticks (e.g., micro storage device (uSD), USB, etc.), optical memories such as compact disc-based ROM (CD-ROM), Digital Video Disks (DVD), Blu-Ray Disks, etc.
Power circuitry 206 may include internal power sources (e.g., a battery, fuel cell, etc.) and/or external power sources (e.g., electromechanical or solar generator, power grid, external fuel cell, etc.), and related circuitry configured to supply NM device 108A′ with the power needed to operate. User interface circuitry 208 may include hardware and/or software to allow users to interact with NM device 108A′ such as, for example, various input mechanisms (e.g., microphones, switches, buttons, knobs, keyboards, speakers, touch-sensitive surfaces, one or more sensors configured to capture images and/or sense proximity, distance, motion, gestures, orientation, biometric data, etc.) and various output mechanisms (e.g., speakers, displays, lighted/flashing indicators, electromechanical components for vibration, motion, etc.). The hardware in user interface circuitry 208 may be incorporated within NM device 108A′ and/or may be coupled to NM device 108A′ via a wired or wireless communication medium. User interface circuitry 208 may be optional in certain circumstances such as, for example, a situation wherein NM device 108A′ is a server (e.g., rack server, blade server, etc.) that does not include user interface circuitry 208, and instead relies on another device (e.g., a management terminal) for user interface functionality.
Communication interface circuitry 210 may be configured to manage packet routing and other control functions for communication circuitry 212, which may include resources configured to support wired and/or wireless communications. In some instances, NM device 108A′ may comprise more than one set of communication circuitry 212 (e.g., including separate physical interface circuits for wired protocols and/or wireless radios) managed by a centralized communication interface circuitry 210. Wired communications may include serial and parallel wired mediums such as, for example, Ethernet, USB, Firewire, Thunderbolt, Digital Video Interface (DVI), High-Definition Multimedia Interface (HDMI), etc. Wireless communications may include, for example, close-proximity wireless mediums (e.g., radio frequency (RF) such as based on the RF Identification (RFID) or Near Field Communications (NFC) standards, infrared (IR), etc.), short-range wireless mediums (e.g., Bluetooth, WLAN, Wi-Fi, ZigBee, etc.), long range wireless mediums (e.g., cellular wide-area radio communication technology, satellite-based communications, etc.), electronic communications via sound or light waves, etc. In one embodiment, communication interface circuitry 210 may be configured to prevent wireless communications that are active in communication circuitry 212 from interfering with each other. In performing this function, communication interface circuitry 210 may schedule activities for communication circuitry 212 based on, for example, the relative priority of messages awaiting transmission. While the embodiment disclosed in
Consistent with the present disclosure, service management circuitry 214 may comprise standalone circuitry in NM device 108A′ such as, for example, an SoC or other single integrated circuit (IC) solution, a chipset, an arrangement of discrete logical and/or analog circuitry, etc. In another embodiment, at least part of the equipment that may be required to execute functionality commonly associated with service management circuitry 214 may reside in other circuitry within NM device 108A′ such as, for example, processing circuitry 202 and/or communication circuitry 212. It may also be possible for at least part of service management circuitry 214 to be encoded in a program that is stored in memory circuitry 206 and executed processing circuitry 202. For example, a programmatic portion of service management circuitry 214 may be based on C (e.g., any of the various versions of C), Go, Python, FORTRAN, Lisp, Visual Basic, iOS, Ruby, Java, AngularJS, Node.js or any other computer programming language existing now or in the future.
Service management circuitry 214 may interact with at least communication circuitry 212 and processing circuitry 202. In an example of operation, service management circuitry 214 may receive inquiries via communication circuitry 212. In an initial phase of non-controller response 114, service management circuitry 214 may at least cause communication circuitry 212 to send a response including at least a user-friendly name for NC device 106 to a probe request (e.g., that was received from OoN device 104′). If a subsequent service discovery request is received in NM device 108′ via communication circuitry 212, service management circuitry 214 may then interact with processing circuitry 202 to determine at least services that are unavailable in NM device 108A′, and may utilize communication circuitry 212 to send a service discovery response including at least information indicating currently unavailable services in NM device 108A′.
OoN device 104′ may comprise, for example, at least processing circuitry 202′, memory circuitry 204′, power circuitry 206′, user interface 208′, communications interface circuitry 210′ and communication circuitry 212′ that may be functionally similar to the corresponding circuitry 200 . . . 212 described above. However, since OoN device 104′ and NM device 108A′ may be of different types (e.g. OoN device 104′ may be a tablet computing device while NM device 108A′ may be a multimedia playback device), the actual implementation of circuitry 200′ . . . 212′ may differ. Circuitry 200′ to 212′ in OoN device 104′ may work alone or together to perform various functions such as, for example, transmitting inquiries to at least NM device 108A′, receiving responses from at least NM device 108A′, generating notifications, etc. For example, processing circuitry 202′ may interact with at least communication circuitry 212′ to transmit and receive messages, and may interact with at least user interface circuitry 208′ to generate a notification (e.g., to present information to a user about services that are currently unable in device NM 108A′, about the consumers of the unavailable services, etc.).
Activity occurring on OoN device 104′ may then cause the transmission of probe requests 306. For example, an application, utility, service or other program may be activated to cause OoN device 104′ to transmit probe requests 306. Normally, NC device 106′ may respond to the probe requests, identify itself as the GO of wireless network 102′, advertise services that are available in the network, etc. However, as shown at 308 NC device 106′ may be unable to respond for various reasons including, for example, device operational conditions (e.g., being in a low power state), environmental conditions (e.g., environmental interference affecting wireless communication), being busy with other activities such as consuming services from NM device 108A′, etc. Regardless of ability of NC device 106′ to respond, non-controller response 114′ may proceed for any or all of NM devices 108A . . . n in wireless network 102′. For example, NM device 108A′ may transmit a probe response including network controller information 310. An example information element (IE) is shown at 320 that may be employed in probe response 310. Example IE 320 may comprise at least an element ID and a “user-friendly” name of NC device 106′ (e.g., a name of NC device 106′ that a user of OoN device 104′ may readily associate with NC device 106′). IE 320 may further comprise information that may be needed to join a Wi-Fi direct network such as a basic service set identifier (BSSID) and a service set identifier (SSID).
Following the reception of probe response 310, OoN device 104′ may transmit service discovery request 312 to, for example, request information about services that are available in at least NM device 108A′. NM device 108A′ may then transmit service discovery response 314 to inform OoN device 104′ about at least currently unavailable services in NM device 108A′. In at least one embodiment, service discovery response 314 may also comprise information about the current consumers of the unavailable services. OoN 104′ may generate notification 316 to, for example, notify a user of OoN device 104′ about currently unavailable services. Notification 316 may optionally be followed by user action 318 wherein the unavailable service/consumer information may be used to free up at least one unavailable service for use by OoN device 104′.
Upon receiving the service discovery request in operation 410, service availability may be determined in operation 412. For example, each NM device 108A . . . n may determine which of the services they offer are currently unavailable. Operation 414 may be optional in that it is not required for all embodiments. In operation 414, consumers for unavailable services may be determined. NM devices 108A . . . n that received the service discovery request in operation 410 may then transmit a service discovery response including at least the unavailable data determined in operation 416 (and optionally in operation 414). At least one service discovery response may be received in operation 418 and a notification may be generated in operation 420. For example, OoN device 104 may display information to a user indicating at least the currently unavailable services in NM devices 108A . . . n that responded to the service discovery, possibly along with information about the consumers of the currently unavailable services.
