EXAMPLE OF A BASIC OPERATION OF A WIRELESS DEVICE

The following is a description of an example of a basic operation on which the present technique is based.

First, an example of wireless packet transmission / reception (Figures 5 and 6) to be performed to stabilize a P2P connection (peer to peer) and operate a specific application will be described below.

Next, an example of the wireless packet transmission / reception (Figure 8) to be performed, prior to a second layer connection, will be described to designate a specific application to use, establish a P2P connection, and operate a specific application.

After that, an example of wireless packet transmission / reception will be described (figure 9) to be performed to start a specific application after establishing a connection in the second layer in a case where the example illustrated in figures 5 and 6 is combined with the example illustrated in figure 8.

Figures 5 and 6 are a flow chart showing an example communication process to be carried out by each device on which the present technique is based.

Specifically, an example of the procedures for establishing a direct connection leading to a connection compatible with the Direct Wi-Fi standard (also called Wi-Fi P2P), which has been adjusted by the WiFi Alliance, is described.

According to Wi-Fi Direct, wireless communication devices detect the existence of one another (Device Discovery and Service Discovery). The devices to connect are then selected, and a direct connection is established between the selected devices by authenticating the device through WPS (WiFi Protected Configuration). According to direct Wi-Fi, the wireless communication devices of a communication group, with one of the wireless communication devices determined to serve as the group owner, some of the wireless communication devices are determined to serve as clients .

In the example communication process illustrated in Figures 5 and 6, however, part of the transmit / receive packet is not shown. For example, at the time of the first connection, packet exchanges are required to use i WPS, and the transmission / reception of an Authentication Request / Response also involves packet exchanges. However, Figures 5 and 6 do not

IMPI

INSTITUTO MEXICANO OE LA FROPIEDAD, INDUSTRIAL

<img file="MX343129B_D0032.tif" />

they show such packet exchanges, and only show the second and subsequent connections. ~~

Although Figures 5 and 6 show an example communication process to be performed between the first wireless communication device 100 and the second wireless communication device 200, the same communication process can be performed between other wireless communication devices.

First, Device Discovery is conducted between the first wireless communication device 100 and the second wireless communication device 200 (501).

For example, the first wireless communication device 100 transmits a Test request (a response request signal), and receives a Test response (a response signal) to the Test request from the second wireless communication device 200. With this, the first wireless communication device 100 and the second wireless communication device 200 can describe the existence of one another. Through the

Device Discovery, you can get the name of the device and the type (TV, PC, smartphone, or the like) of each.

Service Discovery is then conducted between the first wireless communication device 100 and the second wireless communication device 200 (502). By

IMPI

MEXICAN INSTITUTE OF INDUSTRIAL PROPERTY

<img file="MX343129B_D0033.tif" />

For example, the first wireless communication device 100 transmits Service Discovery Query so that it inquires about the service with which the second wireless communication device 200, which has been discovered through Device Discovery, is associated. The first wireless communication device 100 then receives the Service Discovery Response from the second wireless communication device 200, and obtains the service with which the second wireless communication device 200 is associated. That is, the service can be obtained and the like from the other device can be run through Service Discovery. The service of the other device that can be executed can be a service or a protocol (such as DLNA (Digital Living NetWork Alliance) or DMR (Digital Media

Renderer)), for example.

A user then performs an operation to select the pairs (a pair selection operation) (503). This pair selection operation is performed on only one of the first wireless communication device 100 and the second wireless communication device 200 in some cases. For example, a pair selection screen is displayed on the screen unit 170 of the first wireless communication device 100, and the second wireless communication device 200 is selected as

<img file="MX343129B_D0034.tif" />

IMPI

INSTITUTO MEXICANO DE LA PROPIEDAD INDUSTRIAL the pairs in the pair selection screen through a user operation.

After the user select pair operation (503) is performed, the Group Owner Negotiation is conducted between the first wireless communication device 100 and the second wireless communication device 200 (504). In the example illustrated in Figures 5 and 6, as a result of the Group Owner Negotiation, the first wireless communication device 100 becomes an owner 505 of the group, and the second wireless communication device 200 becomes a client 506 .

The procedures (507 to 510) are then carried out between the first wireless communication device 100 and the second wireless communication device 200, to establish a direct connection. Specifically, Association (L2 (second layer) link establishment) (507) and Link Establishment (508) are conducted sequentially. Also, IP Address assignment (509) and L4 configuration on L3 are conducted sequentially by SSDP (Simple Service Discovery Protocol)

<td colspan="2">or the like (510). It should be noted</td><td>than</td><td>L2 (layer</td><td> 2)</td><td>it means</td>

means the fourth layer (transport layer).

The user then performs a specific application designation or start operation (a designation / application start operation) (511). This designation / application start operation is performed on only one of the first wireless communication device 100 and the second wireless communication device 200 in some cases. For example, an application designation / start operation screen (the connection detail selection screen 190 shown in FIG. 4, for example) is displayed on the screen unit 170 of the first wireless communication device 100, and is select a specific application on this designation / start operation screen through a user operation.

After the user performs the designation / application start operation (511), the specific application corresponding to this designation / application start operation is executed between the first wireless communication device 100 and the second wireless communication device 200 (512 ).

In an example case, a connection between an AP (Access Point) and an STA (station) is established within an older specification than the Direct Wi-Fi standard (a specification standardized by IEEE802.il). In this case, there is no way to recognize to which device a connection is established prior to a connection in the second layer (prior to

IMPI

MEXICAN INSTITUTE Dt THE INDUSTRIAL PROPERTY

<img file="MX343129B_D0035.tif" />

association as specified in IEEE802.il).

According to Wi-Fi Direct, on the other hand, information about a few pairs can be obtained when requesting the candidate's pairs in Device Discovery and Service Discovery (option), as shown in Figures 5 and 6. The information about a pair is the type of the fundamental device, the associated specific application, or the like. The user can select pairs based on the information obtained about the pairs.

This mechanism can be extended to realize a wireless communication system that designates a specific application and selects a pair prior to establishing a connection in the second layer, and causes the specific application to start automatically after selection. An example of a sequence to establish a connection in such a case is shown in figure 8. An example structure of the format of a frame to transmit / receive in this communication process is shown in figure 7.

EXAMPLE STRUCTURE OF A TABLE FORMAT

Fig. 7 is a diagram schematically showing an example structure of the format of a frame to transmit / receive in a communication process for each device on which the present technique is based. That is, Figure 7 shows an example structure of a MAC box.

to establish a connection on the second

Specifically, the box format is an example of the box format of an Association Request / Response (527) performing the sequence shown in Figure 8.

It should be noted that the MAC header is formed with the Frame Control (601) through the Sequence Control (606).

When the Association Request is transmitted, B3B2 = ObOO and B7B6B5B4B = ObOOOO are configured in the Frame Control (601). When the Association Response is encapsulated, B3B2 = ObOO and B7B6B5B4 = ObOOOl are configured in Frame Control (601). Here, ObOO means 00 in binary, ObOOOO means 0000 in binary, and ObOOOl means 0001 in binary.

The MAC box shown in Figure 7 basically has the Association Request / Response box format specified in sections 7.2.3.4 and 7.2.3.5 in the IEEE802.11-2007 specification. However, the MAC table includes not only an Information Element (Hereinafter referred to simply as IE) defined in the specification but also an extended IE only.

To indicate the Vendor Specific IE (610), 127 is configured as a decimal number in the IE type (ID of

Information Element (611)). In this case, according to section 7.3.2.26 in the IEEE802.11-2007 specification, a Length field (612) and an OUI field (613) comes after

In vendor-specific content (614), a field indicating the type of vendor-specific IE (type IE (615)) is first configured. Sub-elements (616) can come after IE Type (615).

Sub-elements (616) can include the name of the specific application to use (617) and the role of the device during the operation of the specific application (618). Sub-elements (616) may also include information about the specific application or information such as the port number to use to control the specific application (information for L4 configuration) (619), and information about capabilities in the specific application (capacity information). Here, the Capability information is the information to detect audio streaming / playback support, video streaming / playback support, and the like when the designated specific application is DLNA, for example.

a specific application and select a few pairs prior to establishing a connection in the second layer, and have the specific application automatically start after selection. The flow chart shown in Figure 8 is a modification formed by partially modifying the flow chart shown in Figures 5 and 6, and therefore the explanation of the same aspects as those in Figures 5 and 6 will not be made below.

First, Device Discovery is conducted between the first wireless communication device 100 and the second wireless communication device 200 (521).

Here the Test request (the response request signal) / Test response (the response signal) used in the device discovery stage may include the vendor-specific IE (610) shown in Figure 7. Accordingly, the association with a specific application and the capacity information indicating the role of the device can be played during the operation of the specific application can be acquired in the Device Discovery state. Here, the role of the device can play during the operation of the specific application is the role of a server / client, a master / slave, a source / collector, or the like.

Service Discovery is then conducted between the first wireless communication device 100 and the

IMPI

INSTITUTO MSXICANO DE LA PtOWEDAL; INDUSTRIAL

<img file="MX343129B_D0039.tif" />

second wireless communication device 200 (522).

Here, detailed capability information about the specific application (such as information about the associated media format details in the case of DLNA) can be included in the Service Discovery status. Consequently, detailed capacity information can be acquired in the specific application.

The respective procedures (523 and 524) shown in Figure 8 are equivalent to the respective procedures 503 and 504 shown in Figure 5.

The respective procedures (527 to 529) are then carried out between the first wireless communication device 100 and the second wireless communication device 200, to establish a direct connection.

Here, the frame (MAC frame) shown in Figure 7 is transmitted / received as an Association Request / Response in the Association state (527). Accordingly, the specific application to use after establishing a connection in the second layer can be designated in state (527) of a packet exchange (Association Request / Response) to establish the connection in the second layer. Also, you can include the information needed in using the specific application in step (527).

As described above, in the example illustrated in Figure 8, an exchange of information different from

IMPI

INSTITUTO MEXICANO DE LA M »OT | K> AD INDUSTRIAL these in the example illustrated in figures 5 and 6 are made

<img file="MX343129B_D0040.tif" />

in the stages of device discovery (521) and

Service Discovery (522). With this difference, the user can implicitly designate the specific application to use after the · establishment of a connection in the second layer by selecting a pre-connection device in the second layer.

Also, with the difference in the step (527) of the exchange of a packet to establish the connection in the second layer of the example illustrated in Figures 5 and 6, the application to be used can be automatically determined, and the number of steps to be taken by the user.

Furthermore, compared to the example illustrated in Figs. And 6, step 510 of L4 configuration on L3 by SSDP or the like can be omitted. Consequently, the user may feel that the time is shortened until the application starts.

Now we describe an example case where a specific application is started using the mechanism illustrated in figure 8 after establishing a connection in the second layer. In this case, the mechanism illustrated in Figure 8 implicitly designates the specific application to use in the provider's IE specification (610 shown in Figure 7) included in the Association Request / Response. The

Information necessary to operate the specific application is also included in the vendor-specific IE (610).

As a result, a problem arises in the case where the specific application is started using the mechanism illustrated in Figure 8 after a connection is established in the second layer. This example is illustrated in Figure 9.

Figure 9 is a flow chart showing an example communication process to be carried out by each device on which the present technique is based. Figure 9 illustrates an example communication process to be performed in a case where a specific application is started using the mechanism illustrated in Figure 8 after establishing a connection in the second layer.

The flow chart shown in Figure 9 is an example formed by combining the flow chart shown in Figures 5 or 6 with the flow chart shown in Figure 8, and therefore the explanation of the same aspects as those in Figures 5, 6, and 8 will now be described. Specifically, in the communication process indicated by a rectangle 541, the respective procedures (501 to 512) shown in Figures 5 and 6 are carried out. In the process indicated by a rectangle 543, the respective procedures (521 to 531) shown in Figure 8 are carried out.

An example case where a specific application is started after a connection is established in the second layer, and another application (541) is operated, as shown in Figures 5 and 6, is now described. In this case in Figures and 6, it is now described. In this case, a process is performed to temporarily cut the L2 link (second layer) by a decoupling Request / Response exchange (542), and a re-connection (543) is established using the procedures shown in Figure 8.

As described above, when a specific application is started, a Device Discovery, a second layer connection process, a secure link establishment process, an IP address allocation process, and the like are performed again. Therefore, the collisions due to the use of a source in an increase in the wireless zone, and the user waiting time increases with the time required by those processes.

In a way that avoids the second layer link cut, an L3 / L4 protocol such as SDP can be used in switching to a specific application as in a case where another application is started, as shown in Figures 5 and 6, for example.

In this case, however, the protocol not required in the operation of the specific application has to be supported, as shown in figure 8. In addition, a request

MEXICAN INSTITUTE OF INDUSTRIAL PROPERTY

Application connection is issued from a different layer in this case. Therefore, the implementation of the application trigger portion could become complicated. For example, when a specific application is operated by the mechanism illustrated in Figure 8, a trigger for the specific application is initiated by reusing the existing L2 link (second layer), on the other hand, an L3 / L4 protocol such as SDP. When using an L3 / L4 protocol such as SDP, a trigger for a specific application is emitted from L3 / L4, and a connection management entity must be prepared by more than one layer. As a result, implementation could become complicated.

In view of this, the first embodiment of the present technique suggests an example where a specific application can be easily used even after establishing a connection in the second layer.

cap. Specifically, an example structure is shown “£ Te a supplier-specific action table at the Gtí level^- MAC layer.

Here, a provider-specific action box is an action box containing the provider-specific IE.

When performing a packet swap to start a specific application, the necessary information can be swapped using the action box defined in the IEEE802.11-2007 specification.

It should be noted that the MAC header is formed with the Frame Control (631) through the Sequence Control (636). At

Frame Control (631) in the MAC header, B3B2 = ObOO and B7B6B5B4 = ObllOl are configured. With this setting, this box can be presented as an action box classified as a management box.

Also, 127 is configured as a decimal number in the category field (639) in the box body (637), to indicate that this action box is a vendor specific box in this case, according to section 7.4. 5 in the IEEE802.11-2007 specification, an OÜI field (640) and a Vendor Specific Content field (641) comes after the Category field (639).

Various types of information are configured in the provider-specific content field (641), so that the sequence of operation shown in Figure 16 can be performed.

Here, the various types of information include the name of the specific application to use, the role of the device during the operation of the specific application, and the like. The various types of information also include information about the specific application or information such as a port number to use to control the specific application (information for L4 configuration), and Capacity information in the specific application, for example.

While there may be various methods for implementing the Vendor Specific Content field (641), the following two example structures (shown in Figures 11 and 12) are used in the first embodiment of the present technique.

(IE).

Here, the Vendor Specific Content is preferably divided into more than a portion, thus indicating for what purpose the vendor specific action box is used. For example, the Vendor Specific Content is divided into the vendor specific content type portion (652) and an information element storage portion (653) that follows. That is, the provider-specific content type (652) can indicate for what purpose the provider-specific action box is used. In this form, the type information portion (652) and the information element portion (653) are formed in the action box (provider specific action box).

In the first embodiment of the present technique, the type of each frame is supposedly written to the provider-specific content type (652). The type can be of the type of a request box to indicate to the peers a specific application start or the type of a response box to respond to the indication, while there is a P2P L2 link (second layer), for example.

In the information element storage portion (653), a length field (655) and an OUI field (656) followed, as specified in section 7.3.2.26 in the IEEE802.11-2007 specification. The specific content of

The provider-specific content a type of information element (658) and which constitute the information element. The portion of sub-elements (659) is further divided into sub-elements (660 to

663) .

The type portion (658) contains information indicating that the information element is for starting a specific application, and the sub-element portion (659) contains various types of information. The various types of information in the sub-element portion (659) include the name of the specific application to use (660) and the role of the device during the operation of the specific application (661). The various types of information also include information about the specific application or information such as a port number to use to control the specific application (information for L4 configuration) (662), and Capacity information (663) in the specific application . Capability information is information indicating compatibility with audio transmission / reception, compatibility with video transmission / reception, and the like when the designated specific application is DLNA, for example. The various types of information contained in the sub-element portion (659) will now be described in detail, with reference to Figure 13.

Other than the above, the specific application to start can be designated according to the type of information element in some classification processes, for example. In this case, the sub-element designating the type of the specific application and triggering a startup is not necessary.

For example, the transmitting side (such as the first wireless communication device 100) transmits an action box that includes such an information element requesting a specific application start to the receiving side (such as the second wireless communication device 200 ). Until the action box is received, the receiving side returns an action box as a response that includes the corresponding element information (a response to the action box that a request to start a specific application).

Transmitting / receiving an action box in this way, the intentions of the transmit side and the receive side can match, and a specific application can be launched automatically on both sides. Consequently, the operation of a specific application can be started based on the control information on the L2 link (second layer).

Here, a role can be designated a sub-item in the information item in the response action box to return. In a case where the role is designated as server

in the request, the role of a customer is preferably designated accordingly in a sub-item of the information item in the return response action box.

By another implementation method, a predetermined portion can be encapsulated as the provider-specific content (641) shown in Figure 10. The predetermined portion to encapsulate and transmit is the frame body portion of an association request box or a association response box containing a specific information element. An example structure of the box format according to this implementation method is shown in figure 12.

Fig. 12 is a diagram schematically showing an example structure of the format of a frame to transmit / receive in a communication process between the respective devices in the first embodiment of the present technique. Specifically, Figure 12 shows an example case where the association is used as the Supplier Specific Content of the supplier specific action box shown in Figure 10.

Here, the Vendor Specific Content is preferably divided into more than a portion, thus indicating for what purpose the vendor specific action box is for use, as in the example illustrated in

<img file="MX343129B_D0050.tif" />

Figure 11. For example, Provider Specific Content is preferably divided into the provider specific content type portion (672) and an information element storage portion (673) that encapsulates the table below. That is, the provider-specific content type (672) can indicate what the provider-specific action box is used for.

In the first embodiment of the present technique, the type of each frame is supposedly written to the provider-specific content type (672). The type can be of the type of an action box formed by encapsulating an association request box to indicate to the peers a specific application start, while there is a P2P L2 link (second layer), for example. Alternatively, the type may be of the type of an formed action box encapsulated an association response box responding to the association request box.

The storage portion of the information element (673) that encapsulates a box stored in the body portion (67 5) of an association request box or an association response box to respond to the association request box.

The format of the body portion (675) of an association request box or an association response box to be encapsulated has the same structure as the body of the

IMPI

M INDUSTRIAL PROPERTY

<img file="MX343129B_D0051.tif" />

box shown in figure 7. The format of the body portion (675) is equivalent to that shown in figure 11, and the information element to start a specific application in the body portion (675) is also equivalent so shown in figure 11. Therefore, the detailed explanation of this is not repeated here.

As described above, an association request box is encapsulated to which the information element is added to start a specific application in an action box, and then transmitted to the peers. With this, a request to start a specific application can be transmitted to the peers, while maintaining an existing L2 link (second layer). Until receipt of the request, peers can encapsulate an association response box to which the information element to start the specific application is added in an action box, and return a response. With this, the intentions of the transmit side and the receive side can match, and a specific application can automatically start on both sides. Consequently, the operation of a specific application may start based on the control information on an existing L2 link (second layer).

In Figure 13, an application (such as DLNA) using Wi-Fi CERTIFIED Miracast and P2P is shown as an example application, and the respective information elements are classified into application types 686. It should be noted that Wi-Fi CERTIFIED Miracast is a mirroring technique of transmitting sound and screen video data played from one terminal to the other terminal, and causing the other terminal to output the similar sound and video data, using a technique such as Wi-Fi Direct or TDLS.

An example of an image displayed by the Wi-Fi CERTIFIED Miracast will be described in detail later, with reference to Figure 15.

The names of the associated applications (specific applications) are stored in the Application to be shot (687). For example, a case where application type 686 is Wi-Fi CERTIFIED Miracast is now described. In this case, the information to be stored in the Application to be triggered (687) can be designated in the IE Type (658) shown in figure 11. Consequently, the storage information in the Application to be triggered (687) can be omitted. . In a case

IMPI

MEXICAN INSTITUTE OF INDUSTRIAL PROPERTY where application type 686 is an application that uses P2P,

<img file="MX343129B_D0052.tif" />

a level such as the application using P2P can be designated in the IE type (658) shown in Figure 11. Therefore, in a case where application type 686 is an application using P2P, the name of an application partner (specific application) is stored in the Application to shoot (687).

Meanwhile, information about the role of the first wireless communication device 100 is stored in the Device Role in this application (688). In a case where the application type 686 is Wi-Fi CERTIFIED Miracast, for example, information is stored indicating whether the role of the first wireless communication device 100 is the Source or the collector. That is, information about the Source or Collector compatible with the Wi-Fi Display specification is stored as information about the role of the first wireless communication device 100. The Source and Collector will be described in detail later, with reference to Figure 14. An example case where application type 68 6 is an application using P2P is also described. In this case, the information indicating whether the role of the first wireless communication device 100 is DMS (Digital Media Controller) or DMR (Digital Media) is stored.

Information about the fourth layer (information about an L4 link) is stored in the L4 configuration information (689). In a case where application type 686 is Wi-Fi CERTIFIED Miracast, for example, the information about RTSP specified in the Wi-Fi Display specification is stored. Also, in a case where application type 686 is Wi-Fi CERTIFIED Miracast, for example, information about the port number used in RTSP is stored. At least one piece of the information about RTSP and the information about the port number can be stored. In a case where application type 686 is an application that uses P2P, for example, information about the control protocol supported by this application is stored. Also, in a case where application type 686 is an application that uses P2P, for example, information about the port number used in the control protocol supported by this application is stored. At least one piece of the information about the control protocol and the information about the port number can be stored.

Capacity information is stored in Application Capabilities (690). In a case where application type 686 is Wi-Fi CERIFIED Miracast, for example, content protection compatibility information is stored. This protection compatibility information of

In a case where application type 686 is an application that uses P2P, for example, information about the existence or absence of compatibility with video data and the existence or absence of compatibility with audio data is stored.

Next, the role of a wireless communication device is described in a case where wireless communications are performed by WFD (WiFi Display). Specifically, the WFD Source and WFD Collector are now described in detail.

Fig. 14 is a diagram showing example WFD sessions to be conducted by wireless communication devices in the first embodiment of the present technique.

In Figure 14, a shows an example WFD session to conduct in a case where only audio communications are made. In Figure 14, b shows an example WFD session to conduct in a case where only video communications are made.

In a WFD session, the wireless communication device that plays the role of a transmitter is called the WFD Source. For example, the wireless communication devices (Sources 701 to 704 WFD) shown on the left side in aad in figure 14 are equivalent to the

WFD fonts.

In a WFD session the wireless communication device that plays the role of a receiver is called the WFD Collector. For example, wireless communication devices (Secondary Collector or Primary Collector 705,

Primary Collectors 706 to 708, and a Secondary Collector 709) shown on the right sides in aad in Figure 14 are equivalent to the WFD collectors.

As shown in aad in figure 14, the Sources

WFD 701 to 704 transmit content data (video data and audio data) to WFD Collectors.

Here, WFD collectors are classified into two types: Primary Collectors and Secondary Collectors.

Specifically, as shown in aad in Figure 14, Primary Collectors are WFD Collectors that are compatible with only video content, only audio content, or audio and video content.

As shown in a and d in Figure 14, Secondary Collectors are WFD Collectors that are compatible with audio content only.

THE EXAMPLE SCREEN OF IMAGE DATA

Fig. 15 is a diagram showing an example screen in a case where a wireless communication of image data is performed by the Wi-Fi CERTIFIED Miracast in the communication system 10 in the first embodiment of the present technique. Fig. 15 shows an example case where wireless image data communication is performed between a first information processing device 100 and a second information processing device 200, to display the same image movement on the display units of both devices.

For example, the first information processing device 100 transmits image data to display the same moving image as the motion image displayed on the display unit 170 to the second information processing device 200. For example, in Figure 15, a moving image of a horse running on a beach is displayed on the screen unit 170 of the first information processing device 100. In this case, the control unit 140 of the first ts ·. *

information processing device 100 performs the control to transmit the image data to display the same moving image as the moving image (of a horse running on the beach) displayed in the display unit 170 to the second image processing device 200 information. Here, the image data accompanied by the audio data can be transmitted.

The control unit of the second information processing device 200 causes the display unit 201 to display a moving image (of a horse running on a beach) based on the image data transmitted from the first information processing device 100. If the image data is accompanied by audio data, the control unit of the second information processing device 200 outputs sound based on the audio data transmitted from the first information processing device 100 through an output unit of audio (not shown).

The first information processing device 100 could include an imaging unit to generate a motion image. In that case, the first information processing device 100 can cause the display unit 170 to display the moving image generated by the imaging unit, and transmits image data to display the same moving image as the moving image. to the second information processing device 200, to cause the display unit 201 to display the same moving image.

SPECIFIC APPLICATION

Figure 16 is a flow chart showing an example communication process to be performed by each device in the first embodiment of the present technique. Figure 16 illustrates an example communication process to be performed in a case where a specific application is started after a connection is established in the second layer.

The flow chart shown in Figure 16 is a modification formed by partially modifying the flow chart shown in Figures 5 and 6, and therefore the explanation of the same aspects to those in Figures 5 and 6 will be made below. Specifically, in the communication process indicated by a rectangle 551, the respective procedures (501 to 512) shown in Figures 5 and 6 are carried out.

For example, as shown in Figures 5 and 6, another application is run after an L2 link (second layer) is established (551). After an L2 link (second layer) is established as above, a specific application is started by a packet exchange for a specific application start (552). In this package exchange

IMPI ^{, ΝΪΤ}ϊΰ7? **^and*! Cano 06 THE INDUSTRIAL FROFIEDAD

<img file="MX343129B_D0059.tif" />

for a specific application start, each frame (action frame (shown in Figures 10-12) is transmitted / received). After exchanging the packet for a specific application start, the current data of the specific application (553) can be transmitted.

Compared with the example illustrated in Figure 9, respective procedures such as L2 link cut (second layer) may be temporarily omitted (542). Procedures that can be skipped are the second Device discovery and the second Service Discovery (optional), for example. Also, the procedures that can be skipped are the second Group Owner Negotiation, and the second Association, the second secure link establishment, and the second IP address Assignment, for example. Procedures such as temporary L2 link cut (second layer) (542) can be omitted, the following specific application can be started in a short period of time.

Here, it could be a case where an information exchanger is not performed on the first device discovery (equivalent to 501 shown in Figure 5) included in the packet exchange portion (501 to 512) shown in Figure 16. In this case, it might not be possible to determine if the pairs are compatible with vendor-specific action box exchangers. In this case,

7.3.1.11 of the IEEE802.11-2007 specification, for example, 128 to 255 are designated in the category field in an action box, and a received information element is added to the return response. In this way, a notification can be transmitted that the receiving side is not compatible with specific action tables.

Also, it could be a case where the receiving side can interpret the contents of a provider specific action box, but is not designated to start a specific designated application. In this case, a notification that the receiving side is not supported can be transmitted by returning to a response using an error code defined as a provider-specific information element.

Examples of cases where action charts are used within the vicinity of the IEEE802.11-2007 specification have been described in the first embodiment of the present technique. Here, the GAS (Generic Advertising Service) Public Action Tables defined in the IEEE802.11u specification could be used. In this case, however, the boxes are not encrypted. Therefore, in cases where the

MEXICAN INSTITUTE OF INDUSTRIAL PROPERTY information is exchanged between wireless devices

<img file="MX343129B_D0061.tif" />

While a L2 link (second layer) is already established and a secure link is also established, it is preferred to use action boxes.

Also, in the stage of a packet exchanger to establish the second layer connection, the transmission / reception of a packet containing an information element that includes information other than the necessary information, as well as the designation of the application could be performed. specific to use after connecting the second layer, and in addition to the information needed in using the specific application. For example, a packet containing an information element that includes information indicating whether to start the specific application could be transmitted / received. In this case, a second layer connection could be established with the use of a packet containing an information element that includes information indicating that the specification application is not started. In this case, the specific application can be started after connection establishment, while the second layer connection is maintained with the use of a packet that contains an information element that includes information indicating that the specific application starts in the same item of information. Consequently, the first embodiment of the present technique can also be applied in such a case.

EXAMPLE OPERATION OF A WIRELESS DEVICE^TObE

COMMUNICATION -Figures 17 to 19 show a flow diagram of the procedures in an example communication process to be performed by the first wireless communication device 100 in the first embodiment of the present technique.

First, the correspondence relationship between the procedures shown in Figures 17 to 19 and the respective procedures shown in Figures 5, 6, 8, and

9.

Steps S901 to S905 correspond to 521 and 522 shown in Figure 8. Steps S906 to S909 correspond to 523 shown in Figure 8. Step S910 corresponds to 524 shown in Figure 8. Steps S911 to S915 correspond to

527 and 531 shown in Figure 8.

Step S919 corresponds to 504 shown in Figure 5.

Steps S920 to S926 correspond from 507 to 512 shown in Figures 5 and 6.

Steps S927 through S933 and step S914 correspond to 552 shown in Figure 16. Step S915 corresponds to 553 shown in Figure 16.

First, the control unit 140 drives the

Device Discovery (step S901). The control unit 140 then determines whether an IE indicating the specific application association (equivalent to 610 shown in the

IMPI

MEXICAN INSTITUTE K THE PROPERTY

INDUSTRIAL

<img file="MX343129B_D0063.tif" />

Figure 7) is included in information from peer devices discovered through Device Discovery (step S902). The peer device information is either a Device Discovery request or a Device Discovery response. In a case where an IE indicating the specific application association is included (step S902), the control unit 140 registers the discovered device as a pair associated with a specific application in a list (such as the list 180 of pairs shown in Fig. 3) (step S903). In a case where no IE indicating the specific application association is included (step S902), the control unit 140 registers the discovered device as pairs not associated with any specific application in the list (such as list 180 of pairs shown in Figure 3) (step S904). In a case where an IE indicating the specific application association is included, for example, partner is registered in the specific application association 184 in the list 180 of pairs shown in figure 3. In a case where no IE is included indicating the specific application association, N / A is registered in the specific application association 184.

Control unit 140 then determines whether all peer devices discovered through Device Discovery have been listed (step S905). In

IMPI

MEXICAN INSTITUTE OF INDUSTRIAL PROPERTY a case where not all peer devices have been

<img file="MX343129B_D0064.tif" />

registered, control unit 140 returns to step S902. In a case where all peer devices have been listed (step S905), control unit 140 determines whether a peer designation operation has been performed by the user (step S906).

In a case where no pair designation operation has been performed by the user (step S906), the unit

140 control determines whether a connection request has been received from a peer device (step S907). In a case where no connection request has been received from any peer device (step S907), the control unit 140 is highlighted by (step S908), and returns to step S901. In a case where a connection request has been received from a peer device (step S907), the control unit 140 moves to step S909.

In a case where a user-designate operation has been performed (step S906) or when a connection request has been received from a peer device (step S907), the control unit 140 determines whether a specific application has been designated thereby (step S909). For example, in the connection details selection screen 190 shown in FIG. 4, the user performs a designated pair operation or a designated application specific operation. Also, an analysis is made to

determining whether a specific application has been designated based on the information contained in the connection request received from the peer device.

In a case where a specific application has been designated (step S909), the control unit 140 adds the specific application IE association, and conducts the Group Owner Negotiation (step S910). Through Group Owner Negotiation, the first wireless communication device 100 becomes a GO (Group Owner) or a client.

Control unit 140 then adds the application-specific IE association, conducts the Association, and establishes a connection at the second layer (step S911). Control unit 140 then conducts link establishment

The control unit 140 then causes the specific application to start automatically according to the information in the specific application association IE (step 914), and executes the specific application (step S915). The control unit 140 then determines whether a cut request for the second layer has been received from the user to the peers (step S916). In a case where no second layer cut request has been received, monitoring continues. In a case where a request for

In a case where no specific application has been designated (step S909), the control unit 140 conducts the Group Owner Negotiation, the first wireless communication device 100 becomes a GO (Group Owner) or a client.

Control unit 140 then conducts the Association and establishes a connection in the second layer without adding the application-specific association IE (step S920). Unit

140 control then conducts link establishment

Secure (step S921) and IP Address Assignment (step

S922).

The control unit then analyzes the applications associated by SSDP, and conducts the L4 configuration (step S923).

The control unit 140 then determines whether an application start command has been received from the user or the pairs (step S924). In a case where no application start instruction has been received, monitoring continues.

In a case where an application start instruction has been received (step S924), on the other hand, the control unit 140 starts an application according to the application start instruction (step S925), and executes the application

MEXICAN INSTITUTE OF INDUSTRIAL PROPERTY

<img file="MX343129B_D0067.tif" />

(step S926).

Control unit 140 then determines whether a user-specific application start instruction has been received (step S927). In a case where a specific application start instruction has been received, the control unit 140 suspends the application to be currently executed (step S928). Control unit 140 then transmits the Vendor Specific Action frame of an application start trigger request including the application specific IE association to the peers (step S929). The control unit 140 then receives the Provider Specific Action box of an application start trigger response that includes the specific application association IE from the peers (step S930).

In a case where the specific application is Wi-Fi CERTIFIED Miracast, a user operation to initiate an image data communication, for example, is accepted as a specific application start instruction (step S927). For example, a user operation (such as a touch operation on a touch panel or a pressure operation using an operational tool) to initiate wireless communication of the image data shown in Figure 15 is accepted by the acceptance unit 160 of operation (step S927). In this case, the control unit 140 transmits a provider-specific Action box to the

IMPI

INSTITUTO MEXICANO DE LA FRONBDAD INDUST1IAL pairs based on the acceptance time of the user operation (the user operation to initiate wireless communication of the image data) (step S92 9).

Here, the vendor-specific Action box is the Action box shown in Figures 10 through 12, and contains

INDUSTRIAL wireless image data communication, for example, is accepted as a peer-specific application start instruction. For example, a user operation is accepted to initiate wireless communication of the image data shown in Figure 15 by the peers. In this case, the communication unit 102 receives an Action frame

Provider-specific from the peers based on the acceptance time of the user operation (the user operation to initiate communication of the image data) (step S931).

In a case where the Action frame has not been received (step S931), the control unit 140 determines whether a cut request has been received from the second layer of the user or the peers (step S934). In a case where the second layer cut request has not been received (step S934), control unit 140 returns to step S927, and monitoring continues.

In a case where a second layer cut request has been received (step S934), on the other hand, the control unit 140 performs an application termination process (step

5935), performs a cutting process of the second layer (step

5936), and the communication process ends.

Now the suspension process is described (steps S928 and

S933) to suspend an application it runs. An example case where the application is operated (a first application) is DLNA, and the application (a second application to be done by

Launch during the operation of the first application is Wi-Fi CERTIFIED Miracast described here. That is, the second application is an example of a specific application to start by transmitting / receiving a request / response from the action box.

In a case where the application is suspended is operated, a wireless communication device (the first peer-to-peer wireless communication device 100) transmits a FIN packet (final packet) to the other wireless communication device, for example. A FIN packet can be transmitted in TCP (Transmission Control Protocol) used as HTTP (Hypertext Transfer Protocol) of DLNA, for example. The wireless communication device that has transmitted a request box could transmit a FIN packet, for example. The wireless communication device that has received the FIN packet returns an ACK packet (acknowledgment packet) to the peers (the wireless communication device that has transmitted the packet

FINISH) .

The wireless communication device that has transmitted the ACK packet then transmits a FIN packet to the peers (the wireless communication device to which the ACK packet has been transmitted). The wireless communication device that received the FIN packet (the wireless communication device that transmitted the first

IMPIOS

INSTITUTO MEWCANO OE PROPERTY FIN packet) returns an ACK packet to the jSa'Fé's Cfel wireless communication device that has forwarded the following FIN packet in response to the first FIN packet).

Through those exchanges, a process of closing the TCP port used by DLNA is performed, and the source is released.

An example case where RTSP over Wi-Fi is not described

CERTIFIED Miracast is started when the transmission data has not been finalized by the DLNA (or while a FIN packet and an ACK packet have been exchanged). In this case, the data received by the peers is not delivered to an application but is simply discarded. Therefore, RTSP for Wi-Fi CERTIFIED Miracast can start after the second exchange of a FIN packet and an ACK packet between wireless communication devices is completed.

Alternatively, RTSP for Wi-Fi CERTIFIED Miracast can start after the second exchange of a FIN packet and an ACK packet between wireless communication devices is completed. In such a case, however, the time required for the suspend process (termination process) is undetermined, and therefore, there is a possibility that a time out occurs at an RTSP start. In view of this, it is preferable to set an appropriate time to start RTSP for Wi-Fi CERTIFIED Miracast.

In the process to suspend the application is operated, the UPnP (Universal Plug and Play) TCP port can be left

———————— — ⁷⁴ IMPI

INSTITUTO MEXICANO DE LA RROMEDAO INDUSTRIAL is open, or may be temporarily closed. UPnP is used from device discovery to DLNA capacity confirmation, for example.

In this example, the operation of the first application is terminated based on the operation start time of the second application. However, the first operated application may also terminate after the second application is established and a content data exchange is started.

After the start of the second application operation, the first application operation may not end but continue, and the transmission / reception of data about the first application (the communication volume may be reduced. For example, transmission / Receipt of data about the first application can be reduced based on the time to start the operation of the second application. In this case, a connection to the peers is maintained for which the degree that the wireless communication devices are not disconnected from each other. For example, while video / audio data transmission / reception is not performed to keep the connection alive so that the first application does not cause a timeout. That is, to reduce the transmission / reception of data about the first application, the operating state of the first application is analyzed regularly or irregularly (such as the state of exchange of the information maintained

In the example described above, the first application is DLNA, and the second application is Wi-Fi CERTIFIED Miracast. However, the example above can be applied in cases where the first application is some other application (such as an application for file transfer, copying a file, or the like).

Steps S901 to S926 are an example of the first method described in the claim. Steps S929 to S932 are an example of the second procedure described in the claim.
