In one embodiment, for example, an apparatus may comprise logic, at least a portion of which is in hardware, the logic to send a neighbor awareness networking (NAN) discovery request, receive an NAN discovery response in response to the NAN discovery request, and initiate a Wi-Fi Direct Services application service platform (WFDS-ASP) discovery process based on the NAN discovery response. Other embodiments are described and claimed.
Various embodiments may comprise one or more elements. An element may comprise any structure arranged to perform certain operations. Each element may be implemented as hardware, software, or any combination thereof, as desired for a given set of design parameters or performance constraints. Although an embodiment may be described with a limited number of elements in a certain topology by way of example, the embodiment may include more or less elements in alternate topologies as desired for a given implementation. It is worthy to note that any reference to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of the phrases "in one embodiment," "in some
embodiments," and "in various embodiments" in various places in the specification are not necessarily all referring to the same embodiment.
FIG. 1 illustrates an example of an operating environment 100 such as may be
representative of various embodiments. As shown in FIG. 1, in operating environment 100, a wireless device 102 communicates with a wireless device 104 over a wireless channel 106. In some embodiments, wireless devices 102 and 104 may operate according to one or more Wi-Fi Alliance (WFA) standards. In various embodiments, for example, wireless devices 102 and 104 may communicate according to the WFA Wi-Fi Direct standard, 2010 Release. In some embodiments, wireless devices 102 and 104 may additionally or alternatively operate and/or communicate using interfaces, protocols, and/or standards developed by the WFA Wi-Fi Direct Services (WFDS) Task Group and/or the WFA Neighbor Awareness Networking (NAN) Task Group. The embodiments are not limited in this context.
This disclosure is not limited to Wi-Fi Direct related standards, but may also apply to wireless local area networks (WLANs), such as WLANs implementing one or more Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards (sometimes collectively referred to as "Wi-Fi"). This disclosure may also apply to wireless wide area networks (WWANs), wireless personal area networks (WPANs), and 3G or 4G wireless standards (including progenies and variants) related to wireless devices, user equipment or network equipment included in WWANs. Examples of 3 G or 4G wireless standards may include without limitation any of the IEEE 802.16m and 802.16p standards, 3rd Generation Partnership Project (3GPP) Long Term
Evolution (LTE) and LTE-Advanced (LTE-A) standards, and International Mobile
Telecommunications Advanced (IMT-ADV) standards, including their revisions, progeny and variants.

In various embodiments, wireless device 102 may comprise a device that seeks to obtain a particular type of service from another nearby device. Such a device that seeks to obtain a remotely-provided service may be referred to as a service seeker. In some embodiments, wireless device 104 may comprise a device that is willing to provide a service 108 to other nearby devices. Such a device that is willing to provide a service to one or more remote devices may be referred to as a service advertiser. In various embodiments, the service 108 that wireless device 104 is willing to provide may be of the same type as that sought by wireless device 102. In some embodiments, wireless device 102 may be operative to initiate a discovery process via which it becomes aware that service 108 may be obtained from wireless device 104. In various such embodiments, the discovery process may involve exchanging communications with wireless device 104 over wireless channel 106. The embodiments are not limited in this context.
In some embodiments, in conjunction with discovery of wireless device 104 and service 108 on the part of wireless device 102, wireless devices 102 and 104 may be operative to operate and/or communicate using WFDS application programming interfaces (APIs), methods, events, and/or other primitives. More particularly, in various embodiments, wireless devices 102 and 104 may be operative to operate and/or communicate using APIs, methods, events, and/or other primitives of a WFDS application service platform (WFDS-ASP). The WFDS-ASP may generally comprise a logical entity that defines and/or implements protocol elements and/or functions in support of WFDS service advertising, seeking, discovery, sharing, and/or usage. The embodiments are not limited in this context.
FIG. 2 illustrates an application service platform (ASP) 200 such as may be representative of some embodiments. More particularly, ASP 200 may comprise an example of a WFDS-ASP that defines and/or implements protocol elements and/or functions in support of WFDS service advertising, seeking, discovery, sharing, and/or usage on the part of wireless devices 102 and 104 of FIG. 1. As shown in FIG. 2, ASP 200 comprises elements associated with various types of operations and/or communications that may be associated with WFDS service advertising, seeking, discovery, sharing, and/or usage. In the example of FIG. 2, ASP 200 comprises discovery abstract elements 210, topology management elements 220, and session management elements 230. The embodiments are not limited to these examples.
Discovery abstract elements 210 may comprise logic defining protocol elements and/or functions for implementing device discovery in support of WFDS service advertising, seeking, discovery, sharing, and/or usage. In the example of FIG. 2, discovery abstract elements 210 comprise peer-to-peer (P2P) discovery engine 212. P2P discovery engine 212 may comprise logic defining protocol elements and/or functions to support Wi-Fi Direct (previously known as Wi-Fi P2P) device discovery. Topology management elements 220 may comprise logic defining protocol elements and/or functions for managing inter-device data connections in support of
WFDS service advertising, seeking, discovery, sharing, and/or usage. In the example of FIG. 2, topology management elements 220 comprise P2P connection management engine 222. P2P connection management engine 222 may comprise logic defining protocol elements and/or functions to support Wi-Fi Direct/P2P connection management. Session management elements 230 may comprise logic defining protocol elements and/or functions for managing inter-device communication sessions in support of WFDS service advertising, seeking, discovery, sharing, and/or usage. In the example of FIG. 2, session management elements 230 comprise P2P session management engine 232. P2P session management engine 232 may comprise logic defining protocol elements and/or functions to support Wi-Fi Direct/P2P session management. The embodiments are not limited in this context.
In various embodiments, ASP 200 may define one or more logical interfaces via which one or more services 240 and/or one or more applications 250 may access elements of ASP 200. In some embodiments, such logical interfaces may be described in terms of method and event primitives. In various embodiments, methods may propagate from services 240 and/or applications 250 to elements in ASP 200, and events may propagate from elements in ASP 200 to services 240 and/or applications 250. In some embodiments, one or more applications 250 may access P2P discovery engine 212 via enable 252. Enable 252 may comprise a set of APIs providing interfaces via which to access P2P discovery engine 212. In various embodiments, the elements of ASP 200 may collectively define and/or implement protocol elements and/or functions to support WFDS service advertising, seeking, discovery, sharing, and/or usage via a Wi-Fi Direct network 260. The embodiments are not limited in this context.
In order to make a service available to other devices, a WFDS service advertiser may periodically advertise corresponding service information. As a result of these periodic advertisements, the air interface may become more congested, and the advertiser may incur significant power consumption costs. Additionally, according to existing WFDS protocols, no mechanism is provided via which two sleeping devices may discover each other. In order to enable the use of NAN power-saving discovery techniques to address these issues, it may be desirable to integrate NAN components into a WFDS-ASP.
FIG. 3 illustrates an extended ASP 300 such as may be representative of some
embodiments. More particularly, ASP 300 may comprise an example of an extended version of WFDS-ASP 200 of FIG. 2 that incorporates NAN protocol elements, functions, APIs, methods, events, and/or other primitives in order to enable the integration of NAN discovery procedures with WFDS-ASP discovery procedures in various embodiments. In some embodiments, ASP 300 may be representative of a WFDS-ASP version 2 (WFDS-ASP 2). Like ASP 200 of FIG. 2, extended ASP 300 of FIG. 3 may comprise topology management elements 220, P2P connection management engine 222, session management elements 230, and P2P session management engine 232. Also like ASP 200 of FIG. 2, extended ASP 300 of FIG. 3 may define logical interfaces for use by services 240 and/or applications 250 to access elements of extended ASP 300, and these elements may collectively define and/or implement protocol elements and/or functions to support WFDS service advertising, seeking, discovery, sharing, and/or usage via a Wi-Fi Direct network 260. However, unlike ASP 200 of FIG. 2, extended ASP 300 of FIG. 3 may comprise a NAN discovery engine 364. For example, as shown in FIG. 3, extended ASP 300 may comprise discovery abstract elements 310 that include the NAN discovery engine 364 along with the P2P discovery engine 212 of FIG. 2. The embodiments are not limited to this example.
In various embodiments, NAN discovery engine 364 may implement common functions enabling the performance of NAN power-saving discovery techniques. In some embodiments, NAN discovery engine 364 may be accessible to services 240 and/or applications 250 through a logical interface described in terms of method and event primitives. In various embodiments, methods may propagate from services 240 and/or applications 250 to NAN discovery engine 364, and events may propagate from NAN discovery engine 364 to services 240 and/or applications 250. In some embodiments, NAN discovery engine 364 may utilize time synchronization and periodic discovery frames provided by NAN MAC 366 to enable continuous background scanning and advertisement. In various embodiments, NAN discovery engine 364 may define a NAN discovery process via which service seeking devices and service advertising devices may discover each other while operating in low power states. In some embodiments, extended ASP 300 may define a mechanism by which a WFDS-ASP device discovery sub-process may be skipped following the NAN discovery process. The embodiments are not limited in this context.
In various embodiments, NAN enable 368 may comprise a set of APIs providing interfaces to access NAN discovery engine 364. In some embodiments, NAN enable 368 may comprise a NAN subscribe API primitive that enables a seeker application running in a low power background state to find advertised services during NAN discovery. In various such embodiments, the NAN subscribe API primitive may invoke a NAN discovery result method that returns a list of discovered services. In some embodiments, NAN enable 368 may comprise a NAN publish API primitive that enables an advertiser application running in a low power background state to advertise services during NAN discovery. In various embodiments, extended ASP 300 may enable the performance of NAN power-saving discovery techniques while maintaining interoperability for services 240 advertised in Wi-Fi Direct network 260. The embodiments are not limited in this context.
FIG. 4 illustrates an integrated discovery process 400 such as may be representative of some embodiments. More particularly, integrated discovery process 400 may comprise an example of an integrated discovery process that may be performed in various embodiments by wireless devices 102 and 104 of FIG. 1 in conjunction with extended ASP 300 of FIG. 3. As shown in FIG. 4, integrated discovery process 400 comprises a NAN discovery process 402 and a WFDS-ASP discovery process 404. NAN discovery process 402 may enable a service seeking device and a service advertising device to discover each other while operating in respective low power states. In some embodiments, NAN discovery process 402 may be defined by a NAN discovery engine such as NAN discovery engine 364 of FIG. 3. WFDS-ASP discovery process 404 may comprise a WFDS-ASP device discovery sub-process 406 and a WFDS-ASP service discovery sub-process 408. WFDS-ASP device discovery sub-process 406 may generally comprise a sub-process according to which a service seeking device and a service advertising device may exchange P2P probe request and response frames. In various embodiments, WFDS- ASP device discovery sub-process 406 may be defined by P2P discovery engine 212 of FIGs 2 and 3. In some embodiments, performance of NAN discovery process 402 may enable WFDS- ASP device discovery sub-process 406 to be skipped. As such, WFDS-ASP device discovery sub-process 406 is depicted with a dashed border in FIG. 4. WFDS-ASP service discovery sub- process 408 may generally comprise a sub-process according to which a service seeking device and a service advertising device may exchange P2P service discovery request and response frames. In various embodiments, WFDS-ASP service discovery sub-process 408 may be defined by P2P discovery engine 212 of FIGs 2 and 3. The embodiments are not limited in this context.
It is worthy of note that in some embodiments, an extended ASP such as extended ASP 300 FIG. 3 may define an integrated discovery process comprising a structure that differs from that depicted in the example of FIG. 4. In various embodiments, such a differently-structured integrated discovery process may be defined as an available alternative to an integrated discovery process such as that in FIG. 4, while in other embodiments, such a differently- structured integrated discovery process may be implemented in lieu of an integrated discovery process such as that in FIG. 4. In some embodiments, for example, an extended ASP such as extended ASP 300 of FIG. 3 may define an integrated discovery process according to which both WFDS-ASP device discovery sub-process 406 and WFDS-ASP service discovery sub-process 408 may be skipped. In various such embodiments, a WFDS-ASP discovery process such as WFDS-ASP discovery process 404 may comprise a provision discovery sub-process that is initiated directly following a NAN discovery process such as NAN discovery process 402. Examples of operations and/or communications that may be associated with some such embodiments are discussed below with reference to FIG. 7. The embodiments are not limited in this context.
FIG. 5 illustrates a communications flow 500 such as may be representative of operations and/or communications on the part of a service advertiser (which also may be referred to as a service publisher) and a service seeker (which also may be referred to as a service subscriber) during an integrated discovery process in some embodiments. For example, communications flow 500 may be representative of operations and/or communications on the part of wireless devices 102 and 104 of FIG. 1 during integrated discovery process 400 of FIG. 4. More particularly, communications flow 500 may be representative of various embodiments in which WFDS-ASP device discovery sub-process 406 of FIG. 4 is not skipped during performance of integrated discovery process 400. As shown in FIG. 5, some communications within communications flow 500 may occur during a NAN discovery process, such as NAN discovery process 402 of FIG. 4. Other communications within communications flow 500 may occur during a WFDS-ASP discovery process, such as WFDS-ASP discovery process 404 of FIG. 4. The embodiments are not limited in this context. During the NAN discovery process, at 502 and 504 respectively, the advertiser and the seeker may perform time synchronization. At 506, a service may be selected at the advertiser for advertisement or publication. At 508, an AdvertiseService() or PublishingService90 method may be utilized to cause the service to be advertised or published using an extended WFDS-ASP featuring a NAN discovery engine. At 510, an application at the seeker may determine that a search for services should be performed. At 512, a Subscribe() method may be utilized to cause NAN discovery to be undertaken via the extended WFDS-ASP. At 514, the seeker may transmit a NAN Discovery Request to the advertiser. At 516, the advertiser may utilize local matching techniques to identify services matching specified criteria. At 518, the advertiser may transmit a NAN Discovery Response to the seeker. At 520, a DiscoveryResult primitive may be generated via the extended WFDS-ASP based on the NAN Discovery Response. At 522, a list of available services may be provided to the application at the seeker based on the DiscoveryResult primitive.
During the WFDS-ASP discovery process, at 524, the application at the seeker may select a service for use. At 526, a SeekService() method may be utilized to cause P2P discovery to be undertaken via the extended WFDS-ASP. At 528, the seeker may transmit a P2P Probe Request to the advertiser, and the P2P Probe Request may comprise one or more service hashes. At 530, the advertiser may perform hash matching to identify one or more service names and/or advertisement IDs matching the service hashes in the P2P Probe Request. At 532, the advertiser may transmit a P2P Probe Response to the seeker, and the P2P Probe Response may comprise the one or more service names and/or advertisement IDs identified during the hash matching. At 534, the seeker may transmit a P2P Service Discovery Request to the advertiser, and the P2P Service Discovery Request may comprise one or more service names and/or service information requests. At 536, the advertiser may perform name matching and service information matching techniques to identify advertisement IDs and service statuses for services identified in the P2P Service Discovery Request. At 538, the advertiser may transmit a P2P Service Discovery
Response to the seeker, and the P2P Service Discovery Response may comprise the identified advertisement IDs and service statuses. At 540, a SearchResult primitive may be generated via the extended WFDS-ASP based on the P2P Service Discovery Response. At 542, a list of devices may be provided to the application at the seeker based on the SearchResult primitive. The embodiments are not limited in this context.
FIG. 6 illustrates a communications flow 600 such as may be representative of operations and/or communications on the part of a service advertiser (which also may be referred to as a service publisher) and a service seeker (which also may be referred to as a service subscriber) during an integrated discovery process in some embodiments. For example, communications flow 600 may be representative of operations and/or communications on the part of wireless devices 102 and 104 of FIG. 1 during integrated discovery process 400 of FIG. 4. More particularly, communications flow 600 may be representative of various embodiments in which WFDS-ASP device discovery sub-process 406 of FIG. 4 is skipped during performance of integrated discovery process 400. The embodiments are not limited in this context.
Many of the elements of communications flow 600 match those previously discussed with respect to communications flow 500 of FIG. 5, and in the interest of brevity, their descriptions will not be repeated. However, at 618 in communications flow 600, the advertiser includes a service name in the NAN discovery response that it sends to the seeker. This service name may comprise a service name that matches a service ID included in the NAN discovery request sent at 514. At 626, the SeekService() method is invoked with a flag set to indicate that transmission of a P2P Probe Request can be skipped. As such, the P2P Probe Request at 528, the hash matching at 530, and the P2P Probe Response at 532 in communications flow 500 of FIG. 5 are skipped in communications flow 600. Following invocation of the SeekService() method at 626, the seeker proceeds directly to transmission of the P2P Service Discovery Request at 534. One advantage associated with some such embodiments may be that forgoing the P2P probe request and response exchange of FIG. 5 may result in reduced power consumption on the part of the advertiser and seeker devices. Other advantages are both possible and contemplated, and the embodiments are not limited in this context.
FIG. 7 illustrates a communications flow 700 such as may be representative of operations and/or communications on the part of a service advertiser (which also may be referred to as a service publisher) and a service seeker (which also may be referred to as a service subscriber) during an integrated discovery process in some embodiments. More particularly,
communications flow 700 may be representative of various embodiments in which an integrated discovery process is performed according to which both WFDS-ASP device discovery sub- process 406 and WFDS-ASP service discovery sub-process 408 of FIG. 4 are skipped and a WFDS-ASP provision discovery sub-process is initiated following a NAN discovery process. The embodiments are not limited in this context.
During the NAN discovery process, at 702, an AdvertiseService() method may be utilized by the advertiser to cause a service to be advertised or published using an extended WFDS-ASP featuring a NAN discovery engine. In various embodiments, the AdvertiseService() method may be invoked with an AutoAccept provision. At 704 and 706 respectively, the advertiser and the seeker may perform time synchronization. At 708, an application at the seeker may identify a desired service. At 710, the seeker may invoke a SeekService() method to cause NAN discovery to be undertaken via the extended WFDS-ASP. At 712, the seeker may transmit a NAN
Discovery Request to the advertiser. At 714, the advertiser may perform hash matching to identify one or more service names and/or advertisement IDs that match the desired service. At 716, the advertiser may transmit a NAN Discovery Response to the seeker. At 718, a
SearchResult primitive may be generated via the extended WFDS-ASP based on the NAN Discovery Response. At 720, a list of devices may be provided to the application at the seeker based on the SearchResult primitive.
During the WFDS-ASP discovery process, at 722, the application at the seeker may select the advertiser as a device from which to obtain the desired service. In some embodiments, this selection may be performed based on user input. At 724, the seeker may invoke a
ConnectSessionsO method in order to establish a P2P connection with the advertiser. At 726, the seeker may initiate a WFDS-ASP provision discovery sub-process by sending a P2P provision discovery request to the advertiser. At 728, the advertiser may send a P2P provision discovery response to the seeker in response to the P2P provision discovery request. In various embodiments, the P2P provision discovery response may comprise a status(O) parameter. At 730, the advertiser and the seeker may begin a process by which they become members of a same P2P group in order to establish their P2P connection. In various embodiments they may create and join a new P2P group, while in some other embodiments they may join an existing P2P group. The embodiments are not limited in this context.
