Method and device for controlling connection acceptance in Wi-Fi Aware communication

[0001] The present disclosure relates to a method for controlling connection acceptance for a mobile access point (AP) in Wi-Fi Aware communication.

[0002] The Internet is evolving from a human-centered network where humans generate and consume information into an IoT (Internet of Things) network where distributed components, such as objects, exchange and process information. IoE (Internet of Everything) technology, which combines IoT with Big Data processing technologies through connections with cloud servers, is also emerging. Implementing IoT requires technological elements such as sensing technology, wired and wireless communication and network infrastructure, service interface technology, and security technology. Recently, technologies such as sensor networks, Machine-to-Machine (M2M) communication, and Machine-Type Communication (MTC) are being researched for connecting objects.

[0003] In an IoT environment, intelligent IT (Internet Technology) services that create new value for human life by collecting and analyzing data generated from connected objects can be provided. Through the convergence and integration of existing IT (Information Technology) with various industries, IoT can be applied to fields such as smart homes, smart buildings, smart cities, smart or connected cars, smart grids, healthcare, smart home appliances, and advanced medical services.

[0004] Wi-Fi Aware refers to a technology that extends Wi-Fi capabilities by enabling rapid discovery, connection, and data exchange with other Wi-Fi devices without traditional network infrastructure, internet connections, or GPS signals. Wi-Fi Aware can provide the ability for devices to discover and directly connect with each other without other types of connections. Wi-Fi Aware may also be referred to as NAN (neighbor awareness networking).

[0005] The present disclosure relates to a method for controlling connection acceptance for a mobile AP in a Wi-Fi Aware communication and mobile AP (access point) operating environment.

[0006] A method of operation of a first electronic device supporting Wi-Fi aware communication according to one embodiment of the present disclosure may include: transmitting a neighbor awareness networking (NAN) service discovery frame (SDF) message containing information regarding admission control for a mobile AP-based communication in a first channel supporting Wi-Fi aware communication; receiving an association request from a second electronic device in a second channel supporting mobile AP-based communication when a second electronic device attempts to connect to the mobile AP-based communication based on the information regarding admission control for the mobile AP-based communication; and transmitting an association response corresponding to the association request to the second electronic device.

The control unit may control the transmission of a neighbor awareness networking (NAN) service discovery frame (SDF) message containing information regarding admission control for mobile AP-based communication on a first channel supporting Wi-Fi aware communication. When a second electronic device attempts to connect to the mobile AP-based communication based on the information regarding admission control for the mobile AP-based communication, the control unit may receive an association request from the second electronic device on a second channel supporting the mobile AP-based communication. The control unit may control the transmission of an association response corresponding to the association request to the second electronic device.

[0009] A second electronic device supporting Wi-Fi aware communication according to one embodiment of the present disclosure may include a transceiver; and a control unit. The control unit may receive a neighbor awareness networking (NAN) service discovery frame (SDF) message from the first electronic device, which includes information regarding admission control for mobile AP-based communication, on a first channel supporting Wi-Fi aware communication.

[0024] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the attached drawings.

[0025] In describing the embodiments, technical details that are well known in the technical field to which this disclosure belongs and are not directly related to this disclosure are omitted. This is intended to convey the essence of this disclosure more clearly without obscuring it by omitting unnecessary explanations.

[0026] For the same reason, some components in the attached drawings have been exaggerated, omitted, or schematically depicted. Additionally, the size of each component does not entirely reflect its actual dimensions. Identical or corresponding components in each drawing have been assigned the same reference number.

[0027] The advantages and features of the present disclosure and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present disclosure is not limited to the embodiments disclosed below but may be implemented in various different forms. The embodiments of the present disclosure are provided merely to make the present disclosure complete and to fully inform those skilled in the art of the scope of the disclosure, and the present disclosure is defined only by the scope of the claims. Throughout the specification, like reference numerals refer to like components.

[0028] At this point, it will be understood that each block of the process flow diagrams and combinations of the flow diagrams can be executed by computer program instructions. Since these computer program instructions can be loaded into the processor of a general-purpose computer, a special-purpose computer, or other programmable data processing equipment, the instructions executed through the processor of the computer or other programmable data processing equipment create means to perform the functions described in the flow diagram block(s). Since these computer program instructions can also be stored in computer-available or computer-readable memory that can be directed toward the computer or other programmable data processing equipment to implement the function in a specific way, the instructions stored in computer-available or computer-readable memory can also produce a manufactured item containing means of instruction to perform the function described in the flow diagram block(s). Since computer program instructions can be loaded onto a computer or other programmable data processing equipment, instructions that execute a computer or other programmable data processing equipment by performing a series of operation steps on the computer or other programmable data processing equipment to create a process executed by the computer may also provide steps for executing the functions described in the flowchart block(s).

[0029] Additionally, each block may represent a module, segment, or part of code containing one or more executable instructions for executing a specific logical function(s). It should also be noted that in some alternative execution examples, the functions mentioned in the blocks may occur out of order. For instance, two blocks described in succession may actually be executed substantially simultaneously, or the blocks may be executed in reverse order depending on the corresponding function.

[0030] In this disclosure, the term “part” as used refers to a software or hardware component, such as a Field Programmable Gate Array (FPGA) or an Application Specific Integrated Circuit (ASIC), and the “part” performs certain roles. However, the “part” is not limited to software or hardware. The “part” may be configured to reside in an addressable storage medium or may be configured to run one or more processors. Accordingly, according to some embodiments, the “part” includes components such as software components, object-oriented software components, class components, and task components, as well as processes, functions, attributes, procedures, subroutines, segments of program code, drivers, firmware, microcode, circuits, data, databases, data structures, tables, arrays, and variables. The functions provided within the components and “parts” may be combined into a smaller number of components and “parts” or further separated into additional components and “parts.” In addition, the components and 'parts' may be implemented to utilize one or more CPUs within the device or secure multimedia card. Furthermore, according to some embodiments, the 'parts' may include one or more processors.

[0031] The operating principles of the present disclosure will be described in detail below with reference to the attached drawings. In describing the present disclosure below, specific descriptions of related known functions or configurations will be omitted if it is determined that such detailed descriptions would unnecessarily obscure the essence of the present disclosure. Furthermore, the terms described below are defined in consideration of their functions in the present disclosure, and these may vary depending on the intentions or practices of the user or operator. Therefore, their definitions should be based on the content throughout this specification.

[0032] Each of the station (STA), transmitting device, receiving device, and electronic device used in this disclosure may be referred to as a terminal, mobile station (MS), user equipment (UE), user terminal (UT), wireless terminal, access terminal (AT), terminal, subscriber unit, subscriber station (SS), wireless device, wireless communication device, wireless transmit / receive unit (WTRU), mobile node, mobile, or other terms. Each of the station, transmitting device, receiving device, and electronic device may include a cellular telephone, a smartphone with wireless communication capabilities, a personal digital assistant (PDA) with wireless communication capabilities, a wireless modem, a portable computer with wireless communication capabilities, a shooting device such as a digital camera with wireless communication capabilities, a gaming device with wireless communication capabilities, a music storage and playback device with wireless communication capabilities, an internet consumer device capable of wireless internet access and browsing, as well as portable units or terminals integrating combinations of such capabilities. Additionally, each of the station, transmitting device, receiving device, and electronic device may include, but is not limited to, a Machine-to-Machine (M2M) terminal or a Machine-Type Communication (MTC) terminal / device. In this disclosure, each of the station, transmitting device, receiving device, and electronic device may simply be referred to as a device.

[0033] In this disclosure, "Wireless Local Area Network (WLAN)" and "Wi-Fi" may be used interchangeably. For convenience of explanation, this disclosure describes a WLAN system comprising at least one Access Point (AP) and at least one Station (STA); however, the embodiments of this disclosure are applicable to other WLAN systems, such as, for example, multiple WLANs, peer-to-peer (or independent basic service set) systems, Wi-Fi Direct systems, and / or hotspots.

[0034] Wi-Fi Aware refers to a technology that extends Wi-Fi capabilities by enabling rapid discovery, connection, and data exchange with other Wi-Fi devices without traditional network infrastructure, internet connections, or GPS signals. Wi-Fi Aware can provide the ability for devices to discover and directly connect with each other without other types of connections. Wi-Fi Aware may also be referred to as NAN (neighbor awareness networking).

[0035] Wi-Fi Aware networking can operate by forming clusters with nearby devices or creating a new cluster if a device is the first device in the area. Applications can use the Wi-Fi Aware API (Application Programming Interface) to communicate with Wi-Fi Aware system services that manage the device's Wi-Fi Aware hardware. For example, Wi-Fi Aware network connections can support higher processing speeds over long distances where Bluetooth connections do not reach. For instance, Wi-Fi Aware network connections can be useful for apps that share large amounts of data between users, such as photo sharing apps.

[0036] Figure 1 shows an example of an environment in which a mobile AP and Wi-Fi Aware are used in parallel.

[0037] Mobile APs can provide improved performance compared to NDP (NAN Data Path) (e.g., based on Wi-Fi Aware R4), and the probability that multiple terminals constituting a NAN cluster will connect to the mobile AP instead of the NDP may increase. Consequently, in environments where mobile APs and Wi-Fi Aware are operated together, the performance of the mobile AP may gradually degrade as the number of connected terminals increases.

[0038] In environments where mobile APs and Wi-Fi Aware are operated together, there is a growing need for an Admission Control method to guarantee the Quality of Service (QoS) of mobile APs.

[0039] Referring to FIG. 1(a), when the first electronic device (110) operates as a mobile AP and NAN device, the second to fifth electronic devices (120 to 150) can be connected to the first electronic device (110) via a Mobile AP Link to connect to a mobile AP that provides enhanced performance. In the absence of an Admission Control process for the mobile AP, each of the second to fifth electronic devices (120 to 150) can attempt to connect to the first electronic device (110) via the Mobile AP Link regardless of the performance of the service to be supported (e.g., traffic delay).

[0040] Referring to FIG. 1(b), if the first electronic device (110) operates as a mobile AP and NAN device and there is an Admission Control for the mobile AP, the second electronic device (120) that has been accepted for connection to the mobile AP is connected to the first electronic device (110) via a Mobile AP Link, and the third to fifth electronic devices (150) that have not been accepted for connection to the mobile AP can be connected to the first electronic device (110) via an Aware NDL (NAN Data Link) (or Aware NDP). For example, if the traffic delay required for the service that the second electronic device (120) intends to provide is less than a threshold value, the connection to the mobile AP for the second electronic device (120) may be accepted. For example, if the traffic delay required for the service that the third electronic device (130) intends to provide is greater than a threshold value, the connection to the mobile AP for the third electronic device (130) may not be accepted.

[0041] FIG. 2a illustrates the operation of an access point (AP) and a station (STA) for establishing a Wi-Fi connection.

[0042] Referring to FIG. 2a, the station (220) can transmit or broadcast a probe request message to the access point (210) (S201). According to one embodiment, the probe request message may include information regarding at least one communication capability supported by the station (220).

[0043] The access point (210) can transmit a probe response message in response to the probe request message (S202). Upon receiving the probe response message, the station (220) can transmit an authentication request message to the access point (210) (S203). The access point (210) transmits an authentication response message to the station (220) in response to the authentication request message (S204), and the authentication procedure between the access point (210) and the station (220) can be completed.

[0044] When the authentication process is completed, the station (220) can send an association request message to the access point (210) (S205). According to one embodiment, the association request message may include information regarding at least one capability (e.g., according to IEEE 802.11 standards) to be used for data communication between the station (220) and the access point (210). The access point (210) can generate an association ID for the station (220) and send an association response message to the station (220) (S206).

[0045] FIG. 2b illustrates the operation of a first station and a second station for a Wi-Fi Aware connection. Each of the first station (230) and the second station (240) may also be referred to as a Wi-Fi Aware device or an electronic device.

[0046] Referring to FIG. 2b, when the first station (230) and the second station (240) decide to proceed with a Wi-Fi Aware (or NAN) connection, the first station (230) may transmit at least one discovery beacon to the second station (240) for synchronization (S211, S212). The first station (230) may transmit a synchronization beacon to the second station (240) (S213). The second station (240) may scan at least one discovery beacon and one synchronization beacon and perform a synchronization procedure (or operation) with the first station (230).

[0047] The first station (230) transmits a service discovery frame (SDF) publish message to the second station (240) for service discovery (S214), and the second station (240) can transmit an SDF follow-up message corresponding to the SDF publish message to the first station (230) (S215).

[0048] The second station (240) sends a data path request message to the first station (230) for NDP (NAN data path) setup (S216), and the first station (230) can send a data path response message to the second station (240) (S217). The second station (240) sends a data path confirm message to the first station (230) (S218), and the first station (230) can send a data path key installment message to the second station (240) (S219). When the NDP setup is complete, the first station (230) and the second station (240) can establish a NAN connection (S220).

[0049] According to one embodiment, the first station (230) and the second station (240) may exchange information regarding quality of service (QoS) before the NDP setup procedure. According to one embodiment, the information regarding QoS may be included in the QoS field of an SDF message (e.g., an SDF Publish message, an SDF Subscribe message, and / or an SDF Follow-up message).

[0050] According to one embodiment, the first station (230) and the second station (240) may exchange time synchronization function (TSF) information in a service discovery procedure (e.g., S214 and / or S215) to optimize AP and Wi-Fi Aware scheduling. According to one embodiment, the first station (230) and / or the second station (240) may use the exchanged TSF information to adjust and / or reduce the AP interval (or period) for communication with the access point (AP). For example, the AP interval may be reduced from 8 slots to 5 slots based on the TSF information.

[0051] According to one embodiment, when both the first station (230) and the second station (240) do not transmit and / or receive traffic requiring high QoS when communicating with an access point, more time resources may be allocated to Wi-Fi Aware communication between the first station (230) and the second station (240).

[0052] Figure 3 shows an example of device and service discovery of a Wi-Fi aware device.

[0053] Referring to FIG. 3, at least one electronic device included in the cluster can transmit at least one discovery beacon (310) according to the NAN standard. At least one electronic device can transmit at least one synchronization beacon (320) and / or at least one service discovery frame (330) within a discovery window (DW) (340) that occupies 16 time units (TU) according to the NAN standard.

[0054] For example, DW (340) may occupy 16 TU, and DW interval (360), which is the time interval between DWs (340), may occupy 512 TU. For example, Discovery beacon interval (370), which indicates the transmission interval of at least one discovery beacon (310), may occupy 50 to 200 TU. The time it takes for an electronic device to perform discovery may depend on the DW interval (360).

[0055] According to one embodiment, at least one synchronization beacon (320) may be a signal for maintaining synchronization (e.g., time clock synchronization) between electronic devices included in a cluster. At least one synchronization beacon (320) may include at least one piece of information associated with synchronization between electronic devices.

[0056] According to one embodiment, at least one synchronization beacon (320) may include at least one of an FC (frame control) field indicating the function (e.g., beacon) of a signal, a broadcast address, a MAC (media access control) address of the electronic device that transmitted at least one synchronization beacon (320), a cluster identifier, a sequence control field, a time stamp for a beacon frame, a beacon interval field indicating the interval between the start points of synchronized communication intervals, or capability information of the electronic device that transmitted at least one synchronization beacon (320).

[0057] At least one sync beacon (320) may include an information element related to at least one proximity network, and may include, for example, service-related content that can be provided based on the proximity network. According to the NAN specification, at least one sync beacon (320) may be transmitted by an electronic device defined as an anchor master device, a master device, or a non-master sync device among at least one electronic device in a cluster.

[0058] According to one embodiment, at least one service discovery frame (330) may be a signal for advertising a service between at least one electronic device in a cluster and exchanging information related to said service based on a proximity network. According to the NAN specification, at least one service discovery frame (330) may be a vendor-specific public action frame and may include various fields. For example, at least one service discovery frame (330) may include an information element related to at least one proximity network.

[0059] According to one embodiment, at least one electronic device may transmit at least one discovery beacon (310) within a section other than the DW section (240). The at least one discovery beacon (310) may be a signal of a cluster advertisement function transmitted so that at least one electronic device that has not joined the cluster can discover the cluster.

[0060] According to one embodiment, at least one electronic device that is not participating in the cluster can discover the cluster and participate in the cluster by performing a passive scan to detect at least one discovery beacon (310) transmitted from at least one electronic device participating in the cluster.

[0061] According to one embodiment, at least one discovery beacon (310) may include at least one piece of information for synchronizing with a cluster. According to one embodiment, the discovery beacon (310) may include at least one of a frame control (FC) field indicating the function (e.g., beacon) of a signal, a broadcast address, a media access control (MAC) address of the electronic device that transmitted at least one discovery beacon (310), a cluster identifier, a sequence control field, a time stamp for a beacon frame, a discovery beacon interval field indicating the transmission interval of at least one discovery beacon (310), or capability information of the electronic device that transmitted at least one discovery beacon (310). According to one embodiment, at least one discovery beacon (310) may include at least one information element related to a proximity network.

[0082] Mobile Wi-Fi chipsets can support Multi-Link Operation (MLO), defined since Wi-Fi 7. They can support multi-band communication through a single Upper MAC and Lower MACs and PHYs separated for each band.

[0083] Referring to FIGS. 5a and 5b, examples of MLO between an AP MLD (Multi-Link Device) operating as a mobile AP and a Non-AP MLD are illustrated.

[0084] The MLSR illustrated in FIG. 5a may refer to a method in which links are established on multiple channels, and AP MLD and Non-AP MLD can communicate only on one of the established links (e.g., Radio 1 Channel 1). Referring to FIG. 5a, the electronic device establishes links on the first radio channel (Radio Channel 1) and the second radio channel (Radio Channel 2), respectively, but can communicate through either the first radio channel (Radio Channel 1) or the second radio channel (Radio Channel 2).

[0085] The MLMR illustrated in FIG. 5b may refer to a method in which links are established on multiple channels, and AP MLD and Non-AP MLD can communicate simultaneously on two or more of the established links. Referring to FIG. 5b, the electronic device establishes links on the first radio channel (Radio Channel 1) and the second radio channel (Radio Channel 2), respectively, and can communicate simultaneously through the first radio channel (Radio Channel 1) and the second radio channel (Radio Channel 2).

[0086] Meanwhile, in an environment where mobile APs are operated as Aware to support services requiring high performance, such as VR (Virtual Reality), XR (eXtended Reality), AR (Augmented Reality), and MR (Mixed Reality), if the number of NAN devices connected to the mobile AP increases, channel congestion increases and the communication performance of each NAN device may degrade (e.g., traffic delay of 10 ms or more may occur). In addition, traffic delay performance may worsen depending on the presence of surrounding APs / nodes, and in this case, the requirements for services requiring high performance (e.g., XR) may not be met.

[0087] The present disclosure proposes an Admission Control method for guaranteeing the Quality of Service (QoS) of a mobile AP in an environment where Aware communication and mobile APs are operated in parallel. The present disclosure proposes methods for imposing specific conditions for mobile AP access to limit the number of NAN devices connecting to the mobile AP.

[0088] The present disclosure proposes a method for adding a field for mobile AP connection control to a NAN attribute included in a NAN SDF (Service Discovery Frame) and / or Action Frame.

[0089] According to one embodiment, a NAN SDF Publish message may include an attribute specifying conditions for using a mobile AP. According to one embodiment, the attribute may include information regarding a Service ID and / or traffic patterns (e.g., maximum packet transmission / reception interval, or minimum data transmission rate). According to one embodiment, the attribute may include information regarding the destination server IP address of the service (e.g., XR application server address).

[0090] For example, when a nearby NAN device searches for a service, it checks the attribute included in the NAN SDF Publish message, and if the condition according to the attribute is satisfied, it can connect to the mobile AP. For example, when a nearby NAN device searches for a service, it checks the attribute included in the NAN SDF Publish message, and if the condition according to the attribute is not satisfied, it can connect to the NDP (NAN Data Path).

[0091] A NAN device can set NAN attributes for aware communication. According to one embodiment, a NAN attribute may refer to an element that can be included in a NAN SDF. According to one embodiment, a NAN attribute may refer to an element that can be included in an Action Frame, etc. According to one embodiment, a NAN attribute may include the fields of Table 1.

[0092] [Table 1]

[0093]

[0094] Referring to Table 1, the Attribute ID field may represent an ID identifying the type of the NAN attribute. The Length field may indicate the length of the field included in the NAN attribute. The Attribute Body field may include NAN attribute specific information fields.

[0095] For example, the NAN attribute may include the fields in Table 2.

[0096] [Table 2]

[0097]

[0098] Referring to Table 2, the Attribute ID field may indicate that the type is an Aware-Assisted Mobile AP Attribute. The length field may indicate the length of the field included in the NAN attribute in bytes. The Attribute Body includes NAN attribute specific information fields, and may include, for example, at least one of the fields in Table 3.

[0101]

[0102] Referring to Table 3, the Instance ID field may have the same value as the Instance ID field of the associated Service Descriptor attribute. The Control field may indicate fields present and their length.

[0103] The Service ID of Traffic field may exist optionally (Size (Octets): 0 or 6). The Service ID of Traffic field may indicate a Service ID for traffic used by a mobile AP. According to one embodiment, the Service ID may be securely processed using a hash function (e.g., HMAC-SHA-256 (NAN Group Key, Service Name || (TSF & 0xFFFFFFFFFF800000)).

[0104] The Nominal MSDU Size field may be optional (Size (Octets): 0 or 2). The Nominal MSDU Size field may be an unsigned integer specifying the nominal size in octets of an MSDU (MAC Service Data Unit) or (if A-MSDU (Aggregated-MSDU) aggregation is used).

[0105] The Maximum Service Interval field may be optional (Size (Octets): 0 or 4). The Maximum Service Interval field may be an unsigned integer specifying the maximum interval in microseconds between the start of two consecutive service periods.

[0109] The Peak Data Rate field may be optional (Size (Octets): 0 or 4). The Peak Data Rate field may be the maximum allowable data transfer rate (b / s) specified by the MAC SAP for MSDU or A-MSDU transmission.

[0110] The Delay Bound field may be optional (Size (Octets): 0 or 4). According to one embodiment, the Delay Bound field may be an unsigned integer specifying, in microseconds, the maximum time allowed to transmit an MSDU or A-MSDU from a local MAC SAP to a local MAC sublayer.

[0111] The Target Server IP field may be optional (Size (Octets): 0 or 4 or 6). The Target Server IP field may indicate the IPv4 or IPv6 address of the server corresponding to the destination of the traffic.

[0112] FIG. 6 illustrates a method for admission control of a mobile AP for a specific service according to one embodiment of the present disclosure.

[0113] Referring to FIG. 6, a first NAN device acting as a mobile AP can establish and / or utilize a first link (Link A) for discovery operations (e.g., Synchronized Discovery) and a second link (Link B) for which discovery operations are not performed through the MLSR (Multi-Link Single Radio) method. The first NAN device acting as a mobile AP can establish Wi-Fi communication with a second NAN device that wishes to connect to the mobile AP through the second link (Link B) and the Wi-Fi mobile AP service period.

[0114] The first NAN device may establish a first link (Link A) on the first channel and a second link (Link B) on the second channel through the MLSR method. The first NAN device may be able to communicate on only one of the first channel and the second channel through the MLSR method. In the present disclosure, the first channel may be a channel that supports Wi-Fi Aware communication, and the second channel may be a channel that supports mobile AP-based communication. According to one embodiment, the first channel may be a channel different from the second channel. According to another embodiment, the first channel may be the same channel as the second channel.

[0115] A first NAN device acting as a mobile AP can include an attribute for QoS connection admission control in a NAN SDF Publish message and transmit it through a first link (Link A). The first NAN device acting as a mobile AP can indicate a specific service (e.g., an XR service) in the Service ID of Traffic field included in the NAN attribute within the NAN SDF Publish message. For example, the NAN attribute within the NAN SDF Publish message may include a Length field indicating a value of 6, and a Service ID of Traffic field indicating an XR service (2b9c450f6671).

[0116] A second NAN device that intends to connect to a mobile AP receives a NAN SDF Publish message transmitted from a first NAN device via a first link (Link A) and can check the Service ID of Traffic field included in the NAN SDF Publish message. As a result of checking the Service ID of Traffic field, the second NAN device can perform an Association procedure for the mobile AP only if its traffic is traffic for a specific service (e.g., XR service).

[0117] According to one embodiment, a second NAN device that intends to connect to a mobile AP may transmit an Association Request containing a Stream ID for a specific service (e.g., XR service) to a first NAN device acting as a mobile AP via a second link (Link B). The Stream ID may be a Higher Layer Stream ID Element. The first NAN device acting as a mobile AP may transmit an Association Response indicating successful association to the second NAN device that intends to connect to the mobile AP.

[0118] According to one embodiment, a third NAN device that intends to connect to a mobile AP may transmit an Association Request that does not include a Stream ID for a specific service (e.g., XR service) through a second link (Link B) to a first NAN device that acts as a mobile AP. The first NAN device that acts as a mobile AP may transmit an Association Response that directs the rejection of the Association to the third NAN device that intends to connect to the mobile AP.

[0119] FIG. 7 illustrates a method for admission control of a mobile AP for a specific traffic pattern according to one embodiment of the present disclosure.

[0120] Referring to FIG. 7, a first NAN device acting as a mobile AP can open and / or use a first link (Link A) for discovery operations (e.g., Synchronized Discovery) and a second link (Link B) for which discovery operations are not performed through the MLSR method. The first NAN device acting as a mobile AP can set up Wi-Fi communication with a second NAN device that wishes to connect to the mobile AP through the second link (Link B) and the Wi-Fi mobile AP service period.

[0121] A first NAN device performing the role of a mobile AP can include an attribute for QoS connection admission control in a NAN SDF Publish message and transmit it through a first link (Link A). The attribute for QoS connection admission control may include information regarding requirements for a specific traffic pattern.

[0122] According to one embodiment, a first NAN device performing the role of a mobile AP may transmit a NAN SDF Publish message including a Maximum Service Interval field and a Minimum Data Rate field that indicate requirements for a Traffic Pattern. According to one embodiment, a first NAN device performing the role of a mobile AP may transmit a NAN SDF Publish message including at least one of the fields shown in Table 3 to indicate requirements for a Traffic Pattern.

[0123] For example, in FIG. 7, the NAN attribute within the NAN SDF Publish message may include a Length field indicating a value of 9, a Maximum Service Interval field indicating a Service Interval of up to 10 msec, and a Minimum Data Rate field indicating a Data Rate of at least 2 Mbps.

[0124] A second NAN device that intends to connect to a mobile AP receives a NAN SDF Publish message transmitted from a first NAN device via a first link (Link A) and can check requirement information regarding a traffic pattern included in the NAN SDF Publish message. As a result of checking the requirement information regarding the traffic pattern, the second NAN device can attempt to connect to the mobile AP when the traffic requirement satisfies the specified conditions.

[0125] According to one embodiment, a second NAN device intending to connect to a mobile AP may transmit an Association Request containing an SCS (Stream classification service) Descriptor Element and / or a sufficient TSPEC (Traffic Specification) Element via a second link (Link B) to a first NAN device acting as a mobile AP. The SCS Descriptor Element may include, for example, an SCSID and / or a TCLAS (traffic class). The first NAN device acting as a mobile AP may transmit an Association Response indicating the success of the Association to the second NAN device intending to connect to the mobile AP.

[0126] According to one embodiment, a third NAN device intending to connect to a mobile AP may transmit an Association Request containing an SCS Descriptor Element and / or an insufficient TSPEC Element through a second link (Link B) to a first NAN device acting as a mobile AP. According to one embodiment, the first NAN device acting as a mobile AP may check the Association Request and, if the TCLAS included in the SCS Descriptor Element does not satisfy the conditions, transmit an Association Response instructing the rejection of the Association to the third NAN device intending to connect to the mobile AP. According to one embodiment, the first NAN device acting as a mobile AP may check for an insufficient TSPEC Element included in the Association Request and transmit an Association Response instructing the rejection of the Association to the third NAN device intending to connect to the mobile AP.

[0127] FIG. 8 illustrates a method for admission control of a mobile AP using a traffic destination according to one embodiment of the present disclosure.

[0128] Referring to FIG. 8, a first NAN device acting as a mobile AP can open and / or use a first link (Link A) for discovery operations (e.g., Synchronized Discovery) and a second link (Link B) for which discovery operations are not performed through the MLSR method. The first NAN device acting as a mobile AP can set up Wi-Fi communication with a second NAN device that wishes to connect to the mobile AP through the second link (Link B) and the Wi-Fi mobile AP service period.

[0129] A first NAN device acting as a mobile AP can include an attribute for QoS connection admission control in a NAN SDF Publish message and transmit it through a first link (Link A). The first NAN device acting as a mobile AP can indicate the target server address of a specific service (e.g., XR service) in the Target Server IP field included in the NAN attribute within the NAN SDF Publish message. For example, in FIG. 8, the NAN attribute within the NAN SDF Publish message may include a Length field indicating a value of 4, and a Target Server IP field indicating the target server address for the XR service (e.g., 10.113.120.1).

[0130] A second NAN device that intends to connect to a mobile AP receives a NAN SDF Publish message transmitted from a first NAN device via a first link (Link A) and can check the Target Server IP field included in the NAN SDF Publish message. As a result of checking the Target Server IP field, the second NAN device can attempt to connect to the mobile AP when the destination address of the traffic is the same as the address specified in the Target Server IP field.

[0131] According to one embodiment, a second NAN device intending to connect to a mobile AP may transmit an Association Request to a first NAN device acting as a mobile AP via a second link (Link B) when the destination address of the traffic matches the address specified in the Target Server IP field. The first NAN device acting as a mobile AP may transmit an Association Response indicating successful association to the second NAN device intending to connect to the mobile AP. Subsequently, during a set time interval within the Wi-Fi mobile AP service period, the second NAN device may transmit traffic to a designated server address or receive traffic from a designated server.

[0132] According to one embodiment, a third NAN device intending to connect to a mobile AP can transmit traffic to a non-designated server address via a second link (Link B) even if the destination address of the traffic matches the address specified in the Target Server IP field. At this time, a first NAN device performing the role of a mobile AP can transmit a deauthentication notification to the third NAN device to disconnect the NAN connection.

[0133] FIG. 9 illustrates an example of a method for disconnecting a connection when a device that does not use a specific service performs a mobile AP connection according to one embodiment of the present disclosure.

[0134] Referring to FIG. 9, a first NAN device acting as a mobile AP can open and / or use a first link (Link A) for discovery operations (e.g., Synchronized Discovery) and a second link (Link B) for which discovery operations are not performed through the MLSR method. The first NAN device acting as a mobile AP can set up Wi-Fi communication with a second NAN device that wishes to connect to the mobile AP through the second link (Link B) and the Wi-Fi mobile AP service period.

[0135] FIG. 9 illustrates an example in which a NAN device that does not use a specific service (e.g., XR service) disconnects when performing a mobile AP connection. For example, the embodiment of FIG. 9 may be a situation in which a NAN device that does not use a specific service (e.g., XR service) deceives the initial TSPEC and connects to a mobile AP as a device that supports a specific service (e.g., XR device). For example, the embodiment of FIG. 9 may be a situation in which a NAN device that was using a specific service (e.g., XR service) finishes using the specific service (e.g., XR service) and maintains a connection to the mobile AP.

[0136] The first NAN device acting as a mobile AP can include an attribute for QoS connection admission control in a NAN SDF Publish message and transmit it through the first link (Link A).

[0137] The second NAN device may transmit an Association Request containing a TSPEC element regarding a specific service (e.g., XR service) to the first NAN device acting as a mobile AP. The first NAN device acting as a mobile AP may transmit an Association Response indicating successful association to the second NAN device intending to connect to the mobile AP. Subsequently, during a set time interval within the Wi-Fi mobile AP service period, the second NAN device may not transmit traffic for the specific service (e.g., XR service) (No Traffic from XR Device).

[0138] A first NAN device performing the role of a mobile AP can analyze traffic patterns for a specific service (e.g., XR service) with a second NAN device and send a Deauthentication Notification to the second NAN device to disconnect the NAN connection when traffic occurs below the performance specified in the attribute for QoS connection admission control.
