Detailed description of the invention

First, process when will describe communication connection between each device.Fig. 1 is the figure of the configuration example illustrating the communication system having applied the present invention.In FIG, communication system 100 is by the collaborative operation of radio communication and multiple devices, and performs application program with the system provided a series of services.As it is shown in figure 1, such as, communication system 100 has cell phone 101 and cell phone 102.

Communicated by two kinds of methods first execution that communicates with second of cell phone 101 and cell phone 102 is in communication with each other.First communication is carried out the communication to swap facility information (it is the information relevant with the device performing communication) and performance information (it is formed for the useful information of the connection of the second communication) by for foundation.Such as, use closely adjacent (close proximity) radio communication as the first communication.Second communication is operation collaborative with the application program performed each of cell phone 101 and cell phone 102 at, and the communication of the communication of perform to provide a series of services (application program provides and services).Such as, use near field communication as the second communication.

Notice that " closely adjacent radio communication " means so that the state of distance (such as the most several centimetres) that communication parter is close to visually identify realizes the wireless communications method of communication.Its example is to use the wireless communications method of electromagnetic induction, as non-contact IC (integrated circuit) blocks.Note, hereinafter, unless specifically stated otherwise, otherwise will describe " contact " and " closely adjacent " as above and not differentiate between them.It is to say, the action being described as " contact " should be included in " closely adjacent ".Vice versa.

Further, " near field communication " means the wireless communications method that can communicate under place cell phone 101 and the state of cell phone 102 with closely (such as, about tens meters or less).Its example is bluetooth (registered trade mark) and WiFi (Wireless Fidelity (WiFi authorizes IEEE (Institute of Electrical and Electric Engineers) 802.11x)).

Generally speaking, in the case of the closely adjacent radio communication as the first communication, can easily identify communication parter from the physical restriction of its communication range, and set up communication connection arrange work than in the case of near field communication to arrange work much easier.Such as, in the case of near field communication, in the case of can there is multiple device in communication range, user must specify the device communicated.On the contrary, in the case of closely adjacent radio communication, its can communication range narrow, the most substantially communication parter is limited to a device.The most in this case, the device that request user mobile subscriber is operating oneself is with the closely adjacent device as communication parter, but communication parter is specified in its action itself, therefore can omit the specification (specification) etc. re-entering communication parter.

But, closely adjacent radio communication typically has the message transmission rate lower than near field communication, and is unsuitable for large-capacity data transmission.Further, must be positioned to close to each other at two devices of period that communicate, it is thus possible to there is the situation being difficult to keep its state (position relationships of two devices).Further, the communication between three or more devices becomes difficulty.

According to above some, by communication system 100, perform the cooperation of application program (application program performed at each of cell phone 101 and cell phone 102) with the second communication (near field communication), and use the first communication (closely adjacent radio communication) to send mutually/receive the facility information for the second communication and performance information.Communicate it is to say, cell phone 101 is first carried out first with cell phone 102, and perform the preparation of the connection for the second communication by sending/receive facility information each other.But, it practice, only by facility information, multi-functional poor, thus it is difficult to set up the connection for the second communication.Therefore, cell phone 101 and cell phone 102 exchange include the performance information of more detailed information, and set up the connection for the second communication neatly based on its performance information.When setting up for the connection of the second communication, cell phone 101 uses it second to communicate and perform the linked operation of application program with cell phone 102.

Noting, the composition of the performance information shown in Fig. 6, profile information and content operation authority information is merely illustrative, and can include other unshowned information, and can omit a part for above-mentioned information.Such as, based on the information exchanged with communication parter, the application program managed by performance information merely has to perform predetermined process, and such as, this application program can be to send/receive the application program of information by the first communication (rather than second communication) even another kind of communication.Further, such as, the communication means for the second communication can be fixing, and can omit information relevant with the communication means of the second communication in performance information.

Therefore, cell phone 101 enables to set up communication performing switching when and start the process of application program easily, and can improve the availability of the application program providing the communication between each device.

About as using the network of the second communication generated as above and being distributed the second communication network of content-data by application program from a device to other devices, the situation performing Task Switching with the device of conversion distribution data will be described.

Fig. 7 A and Fig. 7 B is the figure of the example illustrating the communication system having applied the present invention.As shown in Figure 7 A, by communication system 300, using the method described referring to figs. 1 through Fig. 6, device A301, B302 and C303 have pre-build the second communication network 310, and this second communication network 310 is the communication network using the second communication.Second communication network 310 be wherein device A301 as Communications Management Units operation and device B302 and C303 as receive device operation system.It is to say, as indicated by arrows 311 and 312, device A301 such as performs spreading of content-data (such as music or film) to device B302 and C303 and puts (data distribution).Device B302 and C303 plays out while receiving its data.

As shown in Figure 7 B, changing this second communication network 310 to wherein device C303 is the communication network of Communications Management Units.It is to say, device C303 such as performs spreading of content-data (such as music or film) to device A301 and B302 puts (data distribution).Device A301 and B302 is as receiving device operation, and plays out while receiving the data transmitted by device C303.

Communications Management Units (distribution source of flow data) is transformed into another device when, by referring to the method described in Fig. 1 to Fig. 6, even if operation device C303, by contact (on position close) device A301 and B302 again, with referring to figs. 1 through the method described in Fig. 6, communication connection can also be set up, but the communication between device A301 and B302 can not be controlled.Further, even if operation device A301, by contact (on position close) device B302 and C303 again, with referring to figs. 1 through the method described in Fig. 6, it is also possible to set up communication connection, but the communication between device B302 and C303 can not be controlled.

In the case of three or more devices form the second communication network, to be difficult to according to the method migration Communications Management Units described by Fig. 1 to Fig. 6.

Therefore, by communication system 300, perform following process.First, as shown in arrow 321 in Fig. 7 A, device C303 issues the Task Switching order of the conversion of request Communications Management Units to the device A301 as current Communications Management Units.

The device A301 obtaining Task Switching order opens from the second communication disruption with device B302 based on its request.Further, device C303 sets up the second connection communicated with device B302.Therefore, forming the second communication network 310 by device C303 as its center, thus device C303 starts flow data distribution about device A301 and B302, as shown in the arrow 331 and 332 in Fig. 7 B.

Therefore, Communications Management Units easily can be transformed into device C303 from device A301.It is to say, the distribution source of content-data can be easily varied, and the availability of the application program that the communication between each device is provided can be improved.

Its concrete grammar then will be described.Fig. 8 A to Fig. 8 C is the functional block diagram of the configuration example illustrating that the content of device A301, B302 and C303 of belonging in Fig. 7 A to Fig. 7 B broadcasts application program 211.Device A301 to C303 has the configuration substantially the same with referring to figs. 1 through the cell phone 101 in the case of Fig. 6 description.It is to say, device A301, B302 and C303 can be the devices of any kind, but there is the first communication unit 141 and the second communication unit 142 as shown in Figure 2, and there is functional device as shown in Figure 3.It is to say, device A301, B302 and C303 have the switching application program 208 of configuration as shown in Figure 4, and there is content broadcasting application program 211.

Fig. 8 A shows that the content of device A301 broadcasts the configuration example of application program 211.Fig. 8 B shows that the content of device B302 broadcasts the configuration example of application program 211.Fig. 8 C shows that the content of device C303 broadcasts the configuration example of application program 211.The part similar with the configuration described with reference to Fig. 4 has the identical reference being attached to it.

That is, as shown in Figure 8 A, broadcast the function of application program as content, device A301 has main frame (master) and changes processing unit 410, switch control unit 221, application program controlling unit 223, GUI control unit 224 and memory access processing unit 225.

Main frame changes the process of the current hosts (Communications Management Units) that processing unit 410 is carried out in the second communication network 310, and performs the processing unit of the process relevant with changing main frame (Communications Management Units).Main frame changes processing unit 410 to be had upgrading permission unit 411, changes confirmation unit the 412, second communication control unit 413 and profile process 414.

Upgrading allows unit 411 to accept from main frame (Communications Management Units) upgrade request receiving device, and allows or refuse its request.Change confirmation unit 412 and confirm the main frame change receiving device in addition to request source.Second communication control unit 413 disconnects and communicating with as the second of the device B302 receiving device not being upgraded to main frame.Profile process 414, after main frame changes, sends/receives profile information with other devices forming the second communication network 310, and by its content synchronization.It is to say, profile process 814 execution processes to share mutual profile information.

As shown in Figure 8 B, broadcasting the function of application program 211 as content, device B302 has main frame and changes processing unit 420, switch control unit 221, application program controlling unit 223, GUI control unit 224 and memory access processing unit 225.

Main frame changes processing unit 420 and performs to change into the process relevant as the reception device not being the request source being upgraded to main frame with using the device that receives not being upgraded to main frame (request) (that is: main frame (Communications Management Units)).Main frame changes processing unit 420 and has change permission unit the 421, second communication control unit 422 and profile process 423.

Change and allow unit 421 to receive the main frame provided by device A301 as main frame before changing to change (confirmation) and ask, determine whether to be changed about this request, and to determine that result responds.It is optional about whether the determination method that can be changed, but such as can be determined based on user instruction.Second communication control unit 422 is set up and the second communication connection as the device C303 receiving device being upgraded to main frame.After main frame changes, profile process 423 performs the transmission/reception of the profile information of other devices with composition the second communication network 310, and synchronizes its content.It is to say, execution processes to share mutual profile information.

As shown in Figure 8 C, broadcasting the function of application program 211 as content, device C303 has main frame and changes processing unit 430, switch control unit 221, application program controlling unit 223, GUI control unit 224 and memory access processing unit 225.

Main frame changes processing unit 430 and performs the process relevant with the reception device that main frame (Communications Management Units) is changed into the request source that main frame changes.Main frame changes processing unit 430 and has change instruction reception unit 431, upgrade request unit 432, upgrading processing unit the 433, second communication control unit 434 and profile process 435.

Such as, change instruction reception unit 431 and show GUI screen on a monitor, and such as, change instruction from Receiving Hosts such as users.About the device A301 as current hosts, upgrade request unit 432 request is upgraded to main frame (translation host).In the case of having been proven that described request, upgrading processing unit 433 execution processes so that device C303 is upgraded to main frame.It is to say, device C303 is changed to Communications Management Units 301 from receiving device.Second communication control unit 434 is set up and the second communication connection as the device B302 receiving device not also being upgraded to main frame.After main frame changes, profile process 435 performs the transmission/reception of the profile information of other devices with composition the second communication network 310, and synchronizes its content.It is to say, profile process 835 execution processes to share mutual profile information.

Then, the example of main frame shown in such as Fig. 7 A and Fig. 7 B, device C303 handling process during upgrading will be described with reference to the flow chart in Fig. 9 and Figure 10.Note, will suitably be described with reference to Figure 11 to Figure 14.

First, when shown in Fig. 7 A, in step S101, the application program of device A301 performs the content data transmission (spread and put/transmit) put that spreads for content-data.The spread situation about putting of song data is described below, and it uses song data as the example of content-data.It is to say, as the example of application program, use music player application program 212 is described.Needless to say, can be arbitrary content for the content put of spreading, such as moving image, rest image, content of multimedia etc., and application program be also optional.

The monitor of device A301 shows the GUI (such as, as shown in Figure 11) indicating the song data transmitted.

In step S141, the music player application program 212 of device B302 plays out (spread and put/receive) while receiving the song data distributed by device A301.The monitor of display device B302 illustrates the GUI (such as, as shown in figure 12) that music data is in the process being received/playing.

In step S121, the music player application program 212 of device C303 plays out (spread and put/receive) while receiving the song data distributed by device A301.Now, the monitor of device C303 shows the GUI (such as, all GUI as shown in Figure 12) that instruction song data is received/plays.

In this condition, for example user shows GUI screen on the monitor of device C303, such as, as shown in Figure 13, operates its GUI screen, and shows the song title list of the song data of storage in device C303.When user selects one of song therein to play out, the change instruction reception unit 431 of device C303 receives it in step S122 and changes instruction selected as main frame.

In system shown in such as Fig. 7 A and Fig. 7 B, the distribution of song data only can be performed by the device A301 as main frame.It is to say, the distribution of the song data that device C303 has self can not be performed as the device C303 receiving device.The song data itself self having for dispensing device C303, device C303 can only be upgraded to main frame and have no option.Therefore, the play time (point-in-time) of the song data of storage in user selection device C303, change instruction reception unit 431 and regarded as the request being upgraded to main frame, and ask to perform main frame upgrade request about device A301 accordingly with it in step S123.The upgrading of device A301 allows unit 411 to obtain this request in step S102.

Main frame upgrade request 451 in Figure 14 is the figure of the configuration example being shown in the request that step S123 is sent to device A301 from device C303.In fig. 14, main frame upgrade request 451 has main frame upgrade request order 461, new host address 462, new main frame PIN (personal identification number) 463 and new host performance information 464.

Main frame upgrade request order 461 is the request command being upgraded to main frame for request.New host address 462 is facility information, and in the case of allowing this request, is the address (identification information) of the device becoming new main frame after main frame updates.In the case of example in fig. 14, it is provided that address C (it is the address of device C303) is as new host address 462.New main frame PIN 463 is for confirming the key of session (passkey).This is the identification information for confirming to respond which request etc. according to the value of new main frame PIN 463.In the case of example in fig. 14, request the device C303 upgraded produces new main frame PIN 463.For example, offer value here " 1234 " is as new main frame PIN 463.Noting, new main frame PIN 463 can be arbitrary value, and data length is also optional.The performance information of the device that new host performance information 464 is the new main frame after changing as main frame and operates.In the case of example in fig. 14, it is provided that performance information C (it is the performance information of device C303) is as new host performance information 464.

Return Fig. 9, in step S103, change confirmation unit 812 and transmit main frame change request about as the device B302 receiving device not being upgraded to main frame, thereby confirm that whether main frame can change to device C303.

Main frame in Figure 14 changes the figure that request 452 is the configuration example being shown in the request that step S103 is sent to device B302 from device A301.In fig. 14, main frame change request command 465, new host address 466, new main frame PIN 467 and new host performance information 468 are included in main frame upgrade request 451.

It is the order asking whether can change the confirmation of main frame that main frame changes request command 465.New host address 466 is facility information, and is the address (identification information) of the device becoming new main frame after main frame is upgraded.In the case of example in fig. 14, it is provided that address C (it is the address of device C303) is as new host address 466.New main frame PIN 467 is the key for confirming session.In the case of example in fig. 14, with new main frame PIN 463 similarly to new main frame PIN 467 offer value " 1234 ".The performance information of the device that new host performance information 468 is the new main frame after updating as main frame and operates.In the case of example in fig. 14, it is provided that performance information C is as new host information 468.

Returning to Fig. 9, in step S142, the change of device B302 allows unit 421 to obtain its request.When determining whether to be changed, in step S143, change and allow unit 421 to allow response to provide device A301, as the response to this request main frame change.

Main frame in Figure 14 changes the figure allowing response 453 to be the configuration example being shown in the request that step S143 is sent to device A301 from device B302.In fig. 14, main frame change allow response 469, main frame change receive address 470, new main frame PIN 471 and main frame change and accept performance information 472 and be included in main frame and change and allow in response 453.

Main frame changes the response allowing response 469 to be permission main frame change.It is facility information that main frame changes reception address 470, and is the address (identification information) of the device (that is, this main frame changes the transmission sources allowing to respond 453) allowing main frame to change.In the case of example in fig. 14, it is provided that address B (it is the address of device B302) changes reception address 470 as main frame.New main frame PIN 471 is the key for confirming session.In the case of example in fig. 14, provide the value " 1234 " identical with the value of new main frame PIN 463 to new main frame PIN 471.Main frame changes and accepts performance information 472 and be the new main frame after upgrading as main frame and the performance information of device that operates.In the case of example in fig. 14, it is provided that performance information B (it is the performance information of device B302) changes as main frame and accepts performance information 472.

In step S104, the change confirmation unit 412 of device A301 obtains its response.

When obtaining the main frame allowing main frame to change and changing permission response, in step S105, second communication control unit 413 of device A301 disconnects and the communication of the device B302 as the reception device (it is not the request source of main frame upgrading) not being upgraded to main frame.In step S106, upgrading allows unit 411 to provide the response allowing to upgrade about the main frame of device C303 (it is the reception device in request source).

Main frame upgrading permission 454 in Figure 14 is the figure of the configuration being shown in the response that step S106 is sent to device C303 from device A301.In fig. 14, change permission response 473 including main frame, main frame change receives address 474, main frame change accepts performance information 475, new main frame PIN 476, main frame change reception address 477, main frame change accepts performance information 478 and new main frame PIN 479.

It is the response allowing to be upgraded to main frame that main frame changes permission response 473.It is facility information that main frame changes reception address 474, and is the address (identification information) of the device allowing main frame to change.In the case of example in fig. 14, it is provided that address B changes reception address 474 as main frame.Main frame changes and accepts the performance information that performance information 475 is the device allowing main frame to change.In the case of example in fig. 14, it is provided that performance information B changes as main frame and accepts performance information 475.New main frame PIN 476 is the key for confirming session.In the case of example in fig. 14, provide and new value " 1234 " identical for main frame PIN 463 to new main frame PIN 476.

Change at main frame and receive address 477, main frame change accepts performance information 478 and new main frame PIN 479 inputs the information of other reception devices allowing main frame to change.In the case of example in fig. 14, the information of input equipment A301.It is to say, for all reception devices of the second communication network 310, allow to store in 454 address, performance information and main frame PIN in main frame upgrading.But, device A301 has been main frame, therefore can omit new main frame PIN.

Note, when the user at device B302 refuses main frame change, in step S143, the main frame change refusal of the refusal of instruction main frame change is responded (rather than main frame changes permission and responds) and is sent to device A301.When in step S104, when the change confirmation unit 412 of device A301 obtains main frame change refusal response, omitting the process carried out in step S105 by the second communication control unit 413, and process proceeds to step S106.In step S106, upgrading allows unit 411 to provide the response of main frame upgrading refusal about device C303 (it is the reception device in request source).Refusal response terminates described a series of process.It is to say, in the case of device C303 is not to be scalable to main frame.

In step S124, the upgrade request unit 432 of device C303 obtains its response.

When obtaining main frame upgrading and allowing, in step S125 of Figure 10, device C303 is upgraded to main frame by the upgrading processing unit 433 of device C303.When being upgraded to main frame, second communication control unit 434 of device C303 is set up and the second communication connection of device B302 (it is from the reception device disconnected that communicates with the second of device A301).With this process accordingly, in step S144, second communication control unit 422 of device B302 also sets up the second communication connection with device C303.

When setting up the second communication network that wherein device C303 is main frame, in step S127, the profile process 423 of device C303 and device A301 and B302 exchange synchronization profile information.With this process accordingly, in step S107, profile process 414 exchange of device A301 synchronization profile information.Further, in step S145, profile process 435 exchange of device B302 synchronization profile information.It is to say, hereinafter, device A301 to C303 shares up-to-date profile information each other.

In step S128, the music player application program 212 as the device C303 of new main frame performs to be used for the transmission (spread and put/transmit) of the song data put that spreads of content-data.Now, the monitor of device C303 shows instruction is transmitting the GUI (such as, all GUI as shown in Figure 11) of song data.

In step S146, the music player application program 212 of device B302 plays out (spread and put/receive) while receiving the song data distributed by device C303.Now, the monitor of device B302 shows instruction receives/play the GUI (such as, all GUI as shown in Figure 12) of song data.

Returning to Figure 16, in step S262 corresponding with step S142 in Fig. 9, the change of device B302 allows unit 421 to obtain the change request of its main frame.Similarly, in step S292, the change of device D304 allows unit 421 to obtain main frame change request.

Based on its request, each in device B and D determines whether described device can change to main frame.Such as, when determining that permission main frame changes, changing of device B302 allows unit 421 to allow response to be sent to device A301 by illustrating that the main frame allowing main frame to change changes.

As shown in figure 18, the main frame transmitted from device B302 changes permission response 553 and is similar to change with reference to the main frames described by Figure 14 allow response 453.It is to say, main frame changes and allows response 553 to include being similar to main frame to change and allow the main frames of response 469 to change to allow response 569, be similar to main frame and change and receive the main frame of address 470 and change and receive address 570, be similar to the new main frame PIN 571 of new main frame PIN 471 and be similar to main frame and change and accept the main frame of performance information 472 and change and accept performance information 572.That is, in the case of example in figure 18, from device B302, it is provided that address B changes reception address 570 as main frame, there is provided and be similar to the value " 1234 " of new PIN 564 as new main frame PIN 571, and provide performance information B to change as main frame to accept performance information 572.

Returning to Figure 16, in step S204 corresponding with step S104 in Fig. 9, the change confirmation unit 412 of device A301 obtains its main frame and changes permission response.

Similarly, in the case of allowing to change, in step S293, changing of device D304 allows unit 421 to allow response to be sent to device A301 by illustrating that the main frame allowing main frame to change changes.

As shown in figure 18, device D304 the main frame transmitted changes permission response 554 and is substantially similar to main frame change permission response 553.It is to say, main frame changes and allows response 554 to include being similar to main frame to change and allow the main frames of response 569 to change to allow response 573, be similar to main frame and change and receive the main frame of address 570 and change and receive address 574, be similar to the new main frame PIN 575 of new main frame PIN 571 and be similar to main frame and change and accept the main frame of performance information 572 and change and accept performance information 576.That is, in the case of example in figure 18, from device D304, there is provided address D (it is the address of device D304) to change as main frame and receive address 574, there is provided and be similar to the value " 1234 " of new main frame PIN 563 as new main frame PIN 575, and provide performance information D (it is the performance information of device D304) to change as main frame to accept performance information 576.

Returning to Figure 16, in step S205 corresponding with step S104 in Fig. 9, the change confirmation unit 412 of device A301 obtains its main frame and changes permission response.

When obtaining main frame and changing permission response, in step S206 in Figure 17 corresponding with step S105 in Fig. 9, the second communication control unit 13 disconnects and communicating with second of the device B302 as the reception device (being not intended to the request source of main frame upgrading) not being upgraded to main frame.Similarly, in step S207 in Figure 17 corresponding with step S105 in Fig. 9, second communication control unit 413 of device A301 disconnects and communicating with as the second of the device D304 receiving device not being upgraded to main frame.

When communicating disconnection with the second of device B302 and D304, in step S208 in Figure 17 corresponding with step S106 in Fig. 9, the upgrading of device A301 allows unit 411 to allow response to provide from request source as the device C303 receiving device main frame upgrading.

As shown in figure 19, main frame upgrading in this case allows response 555 to be similar to reference to the main frame upgrading described by Figure 14 and allows response 454.nullThat is，Main frame upgrading allows response 555 to include, and being similar to main frame upgrading allows the main frame upgrading of response 473 to allow response 577、It is similar to main frame and changes the main frame change reception address 578 receiving address 474、Be similar to main frame change accept performance information 475 main frame change accept performance information 579、It is similar to the new main frame PIN 580 of new main frame PIN 476、It is similar to main frame and changes the new main frame change reception address 581 receiving address 474、Be similar to main frame change accept performance information 475 main frame change accept performance information 582、It is similar to the new main frame PIN 583 of new main frame PIN 476、It is similar to main frame and changes the main frame change reception address 584 receiving address 477、Be similar to main frame change accept performance information 478 main frame change accept performance information 585 and be similar to the new main frame PIN 586 of new main frame PIN 479.

That is, it is provided that for allowing the information of each device (in the case of the example in Figure 19, device A301, B302 and D304) that main frame upgrade as main frame upgrading permission response 555.

In the case of example in Figure 19, there is provided address B to change as main frame and receive address 578, there is provided performance information B to change as main frame and accept performance information 579, there is provided address D to change as main frame and receive address 581, and provide performance information D to accept performance information 582 as main frame change, there is provided address A to change as main frame and receive address 584, and provide performance information A to accept performance information 585 as main frame change.Further, each of which in new main frame PIN 580, new main frame PIN 583 and new main frame PIN586 has the value " 1234 " being similar to new main frame PIN 563.

It is to say, for forming each device of the second communication network 310, it is necessary to occur main frame to change.

In step S234 in Figure 17 corresponding with step S124 in Fig. 9, the upgrade request unit 432 of device C303 obtains main frame upgrading and allows response.

Noting, in the case of refusal main frame changes, step S263 in figure 16, the change permission unit 421 of device B302 is refused to respond rather than change to allow to respond to the change of device A301 transmission instruction refusal main frame change.Similarly, in the case of refusal main frame changes, step S293 in figure 16, the change permission unit 421 of device D304 is refused to respond rather than change to allow to respond to the change of device A301 transmission instruction refusal main frame change.

Device A301 change confirmation unit 412 step S204 in figure 16 or S205 obtain main frame change refusal response time, omit step S206 in Figure 17 and the various process of S207, and flow process proceed to step S208 in Figure 17.In step S208, upgrading allows unit 411 to provide main frame upgrading refusal response as the device C303 receiving device being used for asking source.Responded by refusal here, terminate described a series of process.It is to say, in this case, device C303 is not upgraded to main frame.In this case, main frame remains device A301.

When obtaining main frame upgrading and allowing, in step S235 in Figure 17 corresponding with step S125 in Figure 10, device C303 is upgraded to main frame by the upgrading processing unit 433 of device C303.

When being upgraded to main frame, in step S236 in Figure 17 corresponding with step S126 in Figure 10, second communication control unit 434 of device C303 is set up and is connected with second radio communication of device B302.Similarly, in step S237 in Figure 17 corresponding with step S126 in Figure 10, second communication control unit 434 of device C303 is set up and is connected with second radio communication of device D304.

With process here accordingly, in step S264 in Figure 17 corresponding with step S144 in Figure 10, second communication control unit 422 of device B302 sets up the second communication connection with device C303.Similarly, in step S294 in Figure 17 corresponding with step S144 in Figure 10, second communication control unit 422 of device D304 sets up the second communication connection with device C303.

When setting up the second communication network 310 that wherein device C303 is main frame, in step S238 in Figure 17 corresponding with step S127 in Figure 10, the profile process 423 of device C303 performs exchange synchronization profile information with each in device A301, B302 and D304.

With process here accordingly, in step S209 in Figure 17 corresponding with step S107 in Figure 10, profile process 414 exchange of device A301 synchronization profile information.Similarly, in step S265 in Figure 17 corresponding with step S145 in Figure 10, profile process 435 exchange of device B302 synchronization profile information.In step S295 in Figure 17 corresponding with step S145 in Figure 10, profile process 414 exchange of device D304 synchronization profile information.It is to say, hereinafter, each of which in device A301 to D304 shares up-to-date profile information each other.

In step S239 in Figure 17 corresponding with step S128 in Figure 10, as new main frame device C303 music player application program 212 about for content-data spread in device A301, B302 and the D304 put each perform song data distribution (spread and put/transmit).Now, the monitor of device C303 illustrates transmitting the GUI (such as, all GUI as shown in Figure 11) of song data.

In step S210 of Figure 17 corresponding with step S108 in Figure 10, the music player 212 of device A301 plays out (spread and put/receive) while receiving data from device C303.The monitor of device A301 illustrates the GUI (such as, all GUI as shown in Figure 12) receiving/play song data.

In step S266 in Figure 17 corresponding with step S146 in Figure 10, the music player 212 of device B302 plays out (spread and put/receive) while receiving song data from device C303.The monitor of device B302 illustrates the GUI (such as, all GUI as shown in Figure 12) receiving/play song data.

In step S296 in Figure 17 corresponding with step S146 in Figure 10, the music player 212 of device D304 plays out (spread and put/receive) while receiving song data from device C303.The monitor of device D304 illustrates the GUI (such as, all GUI as shown in Figure 12) receiving/play song data.

As mentioned above, even if the quantity performing to receive in the second communication network of Task Switching device wherein is greatly increased, the quantity of the device being only similar to said apparatus B302 increases, and can be easily achieved Task Switching by the process of the situation of the second communication network being similar to be made up of device A301 to C303.

It is to say, the availability of the application program providing the communication between each device can be improved.

By each in above example, have been presented for for explanation be updated performing afterwards by the second communication network 310 profile information exchange and synchronize (as, step S107 in Figure 10, S128 and S146) the description of each device, but in such a case, it is possible to exchange is performed for other information (being not only profile information) and synchronizes.Such as, each device the facility information of each device and performance information can be swapped, synchronization etc..

As it has been described above, in the case of the device configuration updating the second communication network 310, this information communicates with communicating with second by first and swaps.Therefore, terminating the renewal of the second communication network when, each device obtains the information of other devices.However, it is possible to there is a case in which, wherein after updating the second communication network 310, such as user changes device and arranges to update facility information and performance information for each device.In this case, there is such worry: the mutual information making each device have by sending updating the second communication network 310 when/receiving is no longer up-to-date information.After updating the second communication network 310, it is possible to use facility information and performance information, therefore unless this information is up-to-date, otherwise it is likely to occur problem when using its information.

Therefore, as it has been described above, by not only exchange synchronization profile information, but also exchange synchronizer information and performance information, each device can stably share up-to-date information.

Now, in addition to being only used for Communications Management Units as above and changing (Task Switching), each device of the second communication network 310 formed after changing information (device information, performance information, profile information etc.) that share, that belong to each device may be used for following process.Such as, information here can be also used for the renewal of the configuration of the second communication network 310, such as, deletes or adding set.

The renewal of such second communication network 310 will be described.First, the situation that new equipment adds to the second communication network 310 will be described.Hereinafter, the example of the situation that new equipment (device D304) adds to the second communication network 310 being under the state shown in Fig. 7 A will be described.

As shown in FIG. 20 A, about communication system 300, by using the method described referring to figs. 1 through Fig. 6, device A301 and device C303 has pre-build the second communication network 310 (it is with the second communication network communicated).

Device A301 to C303 uses its second communication network 310, and as indicated by arrow 311 and 312, performs spreading of content-data (such as music, film etc.) and put (data distribution).That is, device A301 operates as Communications Management Units, and perform the distribution of content-data (flow data), and each of which operation in device B302 and C303 is for receiving data, and play out while receiving the data distributed by device A301.

About this situation, in order to device D304 being added to the second communication network 310 and allowing to participate in (participation), and it is the reception device put that is used for spreading by device D304 operation, in the case of referring to figs. 1 through the method described by Fig. 6, it is necessary to set up the second communication between device D304 and device A301.It is to say, device D304 must reach over to (close on position) arrives the device A301 as Communications Management Units, exchange mutual facility information and performance information by the first communication, and set up the second communication.

But, in all cases, device D304 may approaching device A301 the most in position, and actually there may be device D304 is positioned close to device B302 or C303 may easier situation.But, in the case of referring to figs. 1 through the method described by Fig. 6, even if device D304 contacts (close on position) with device B302 or C303, the second communication between device D304 and B302 (or C303) can also be set up, but between device D304 and A301, do not set up the second communication.It is to say, with it, device D304 does not receives the data from device A301 distribution.

Further, about the method being described above referring to figs. 1 through Fig. 6, can be performed from the first communication to the switching of the second communication by using GUI to be confirmed whether by user.But, in the case of device D304 is added to the second communication network (as shown in FIG. 20 A) formed by multiple devices, when device D304 is contacted (on position close) to device A301, the user of device B302 or C303 can not refuse the participation of device D304.

Further, about referring to figs. 1 through Fig. 6 in the process described above, there is not the concept of the authority of content operation about device A301.Which such as, about communication system 300, device A301 can be made about the instruction distributing content from device B302 to the D304 being positioned at reception device side.In this case, the content distribution of the device A301 as Communications Management Units can be controlled if located in the device receiving device side and without any condition, then the faulty operation carried out by unfamiliar user may cause the problem for other users.Therefore, it is desired for limiting operating right, but about the method being described above referring to figs. 1 through Fig. 6, does not has such concept.

Accordingly, with respect to communication system 300, perform following process.It is to say, as shown in fig. 20b, (close on position), to receiving device (e.g., device C303), sets up the first communication, as indicated by arrow 341 between device C303 and D304 by being contacted by device D304.In the case of by its first communication exchange equipment information and performance information, the information of device A301 is provided device D304 by device C303.As shown in Figure 20 C, by hand-off process, device D304 uses the information of device A301 to set up the second communication with device A301.Therefore, device D304 can participate in the second communication network as receiving device, and as indicated by arrow 313, device D304 can play out while the data of device A301 distribution receiving.

It is to say, by setting up the first communication with the device C303 not performing the second communication, device D304 can set up the second communication with not having the device A301 that set up first communicate.Therefore, the work that device D304 adds to the second communication network 310 becomes easy, and can improve the availability of the application program providing the communication between each device.

Further, at device D304 display reminding user about whether can be by the GUI of said process adding set B302 or C303.After the instruction shown by GUI, the user of device B302 or C303 allows or the interpolation of refusal device D304.Therefore, even if the user not performing direct second device communicated with device D304 can also control whether adding set D304.

Therefore unknown devices (user) can be suppressed to participate in, thus can easily improve the safety of the second communication network 310.Such as, in the case of device A301 is to have the high device (such as server) sharing speed, device A301 substantially attempts also distributing data to device D304, but, user for device B302 or C303 of personal use may not want that the personal information providing oneself to unknown subscriber (device D304), i.e., it may be undesirable to participate in the second communication network 310.Also it is possible to there is a case in which, wherein the user of device A301 and the user of device D304 recognize each other, but the user of the user of device B302 or C303 and device D304 does not knows each other.In this case, the user of device B302 or C303 undesirably may provide the personal information of oneself to device D304.Further, it is understood that there may be such situation, during wherein device D304 participates in the second communication network 310, and there is no the knowledge of the user of device B302 or C303, and provide it by personal information.As it has been described above, by performing the confirmation whether participated in, such problem can be suppressed to occur, thus can easily improve the safety of the second communication network 310.It is to say, the availability of the application program providing the communication between each device can be improved.

Further, device B302 or C303 shows the GUI confirming whether device D304 has the content operation authority about device A301.The user of device B302 or C303 controls whether to give device D304 by content operation authority according to this GUI.Therefore, it can suppress the authority of unknown devices (user), thus can improve the safety of the second communication network 310.It is to say, the availability of the application program providing the communication between each device can be improved.

Figure 21 A and Figure 21 B is the functional block diagram of the configuration example illustrating that the content of device A301 and B302 belonged in Figure 20 A to Figure 20 C broadcasts application program 211.Device A301 with B302 has the configuration substantially the same with referring to figs. 1 through the cell phone 101 in the case of described by Fig. 6.It is to say, device A301 and B302 can be the device of any kind, but there is the first communication unit 141 and the second communication unit 142 as shown in Figure 2, and there is functional device as shown in Figure 3.It is to say, device A301 and B302 has the switching application program 208 of configuration as shown in Figure 4, and there is content broadcasting application program 211.

Figure 21 A shows that the content of device A301 broadcasts the configuration example of application program 211.Figure 21 B shows that the content of device B302 broadcasts the configuration example of application program 211.There is the identical reference investing it with the part similar with reference to the configuration described by Fig. 4.

Self address 677 is facility information, and is Self address information (identification information).In the case of example in fig. 25, it is provided that the address (address D) of device D304 is as Self address 677.Self performance information 678 is the performance information of device self.In the case of fig. 25, it is provided that performance information D (it is the performance information of device D304) is as self performance information 678.New main frame PIN 679 is the new main frame PIN provided from the first communication connection destination.In the case of example in fig. 25, it is provided that " 1234 ", as new main frame PIN 679, are similar to the new main frame PIN 673 provided by device C303.The value instruction configuration information 662 of the new main frame PIN 679 shared with new main frame PIN 673 is the information corresponding with configuration information 661.Noting, new main frame PIN 679 can be arbitrary value, and data length is optional.

From this exchange of information, the facility information (address) of device C303 acquisition device D304 and performance information.Further, in addition to the facility information (address) and performance information of device C303, the facility information (address) of device D304 also acquisition device A301 and performance information, and indicate whether the information of content operation authority.

Returning to Figure 23, at the end of the exchange of the configuration information carried out by the first communication, the interpolation of device C303 entrusts processing unit 634 to use the second communication in step S327, and performs to entrust request for the interpolation of device D304 about device A301.Adding in Figure 25 entrusts the information that request 663 instruction now provides to device A301.

In the case of example in fig. 25, add and entrust request 663 to include adding trust request command 680, adding set address 681, adding set performance information 682, new main frame PIN information 683 and adding set content operation authority 684.Of course, it is possible to include information in addition.For example, it is possible to additional Self address or self performance information.But, owing to using the existed second communication to transmit data here, therefore even if there be no Self address or the self performance information of instruction transmission destination, device A301 can also identify device A301.

Adding trust request command 680 is the order that device D304 is added to the second communication network 310 by request unit A301.Adding set address 681 is facility information, and is intended to add to the address information of the device of the second communication network 310.In the case of example in fig. 25, it is provided that address D is as adding set address 681.Adding set performance information 682 is intended to add to the performance information of the device of the second communication network 310.In the case of example in fig. 25, it is provided that performance information D is as adding set performance information 682.New main frame PIN 583 is the information similar with above-mentioned new main frame PIN 673 grade.In the case of example in fig. 25, adding and entrust request corresponding with above-mentioned process, thus offer and new main frame PIN 673 and new value " 1234 " identical for main frame PIN 679 are as new main frame PIN 683.Adding set content operation authority 684 is the information whether instruction device to be added gives the operating right of the content of the device as host service function, and is analogous to the information of content operation authority 676.In the case of example in fig. 25, it is provided that for the information of the effect of " there is broadcasting control " as adding set content operation authority 686.

In step S302, the interpolation of device A301 is entrusted receiving unit 611 to obtain such interpolation and is entrusted request.In step S303, add confirmation unit 612 on the monitor of device A301, show GUI, and be confirmed whether to allow adding set with user.

Such as, with " attachment means D？" message together, show the selection option of "Yes" and "No" on the GUI screen.The user of device A301 selects one of "Yes" and "No", thereby indicates that the intention of the user of interpolation about device D304.In the case of being selected "Yes" by user, in step S304, add and entrust receiving unit 611 to perform about adding the response entrusting request about device C303 via the second communication, and allow the interpolation of device D304.Response 664 in Figure 25 indicates the configuration example of the information now providing device C303 from device A301.

In the case of example in fig. 25, response 664 includes adding entrusts permission response 685 and new main frame PIN 686.Of course, it is possible to include information in addition.

Interpolation is entrusted and allowed response 685 is about the response adding trust request command 680, and indicates permission to add.New main frame PIN 686 is analogous to the information of each above-mentioned main frame PIN.Here response processes corresponding to each in above-mentioned process, in the case of example the most in fig. 25, it is provided that with new main frame PIN 673, new main frame PIN 679 and newly the most identical for main frame PIN 683 value " 1234 " as new main frame PIN 686.

In step S328, the interpolation of device C303 entrusts processing unit 634 to obtain its response.

The exchange of this information makes as facility information (address) and the performance information also the most not being able to acquisition device D304 by the device A301 of the Communications Management Units of device D304 contact (on position close).Further, device C303 it is known that be allow for the interpolation of device D304 by device A301.

Note, in step S303, in the case of the interpolation that the user of device A301 selects "No" and refuses device C303, in step S304, add and entrust receiving unit 611 to entrust request about device C303 in response to adding via the second communication, and refuse device D304.The response of this refusal terminates described a series of process.It is to say, in this case, the participation remover C303 from the second communication network 310.

Now, with the device B302 receiving device being also not in contact with (on position close) arriving as device D304, device A301 confirms that device adds.It is to say, step S305 in fig. 24, adding of device A301 confirms that control unit 613 uses the second communication with the confirmation of the interpolation about device B302 request unit D304.Interpolation confirmation request 665 in Figure 25 shows the information now provided by device A301.

In example in fig. 25, add confirmation request 665 and be analogous to add the information of confirmation request 663.Include adding trust request command 687, adding set address 688, adding set performance information 689 and adding set content operation authority 690 it is to say, add confirmation request 665.Of course, it is possible to include information in addition.

Add confirmation request order 687 and be analogous to add the information of confirmation request order 680.In the case of adding set address 688 is analogous to the information of adding set address 681, and example in fig. 25, it is provided that address D.In the case of adding set performance information 689 is analogous to the information of adding set performance information 682, and example in fig. 25, it is provided that performance information D.

Adding set content operation authority 690 is analogous to the information of adding set content operation authority 684.In the case of fig. 25, it is provided that for the information of " exist play control " effect as adding set content operation authority 690.

In step S372, confirmed that receiving unit 621 obtains this information by the interpolation adding the device B302 that confirmation request 665 provides as mentioned above.In step S373, add confirmation unit 622 on the monitor of device B302, show GUI screen, and accept user instruction.Such as, with message " attachment means D？" together, show the selection option of "Yes" and "No" on the GUI screen.When user selects "Yes", in step S374, the interpolation of device B302 confirms that receiving unit 621 communicates about device A301 in response to adding confirmation request via second, and allows the interpolation of device D304.Response 666 in Figure 25 shows the configuration example of the information now provided to device A301 by device B302.

About the example in Figure 25, response 666 includes that adding confirmation allows response 691.Of course, it is possible to include information in addition.Add and confirm to allow response 691 to be analogous to add the information confirming to allow response 685.In step S306, the interpolation of device A301 confirms that control unit 613 obtains its response.

The exchange of such information makes the device B302 also not contacting (close on position) with device D304 be able to know that and has contacted (close on position) device D304.And it is possible to control whether can be with adding set D304.

It is to say, in step S373, the user of device B302 select "No" and refuse device C303 interpolation in the case of, in step S374, add and confirm that receive unit 621 transmits the response of instruction refusal via the second communication about device A301.The response of this refusal terminates described a series of process.It is to say, in this case, the participation remover C303 from the second communication network 310.

Therefore, use the second communication (wherein, performing spreads puts), the communication between device A301 and B302 can be performed.It is to say, device A301 and B302 can perform the exchange of above-mentioned information, and do not stop spreading putting.

The second communication at the end of above process, between enabled device A301 and C303.It is to say, second communication control unit 614 of device A301 is set up second each other with second communication control unit 642 of device D304 in step S354 of Figure 24 and is communicated in step S307 of Figure 24.

When having been set up the second communication, in step S308, the profile process 615 of device A301 uses the second communication and each device exchange in device B302 to D304 synchronization profile information.With this process accordingly, in step S375 of Figure 24 the profile process 623 of device B302, in step S329 of Figure 24 the profile process 635 of device C303 use with each of which in the profile process 643 of device D304 in step S355 second communicate with device A301 exchange also synchronization profile information.It is to say, hereinafter, each device of device A301 to D304 shares up-to-date profile information each other.

Processed by above, as shown in Figure 20 C, device D304 is added to the second communication network 310, and enables the distribution from device A301 to the content-data of device D304.Therefore, the music player application program 212 of device A301 uses the second communication to transmit for spreading the song data (spread and put/transmit) put about device B302 to D304 in step S309.

In step S376, each of which in the music player application program 212 of device B302, the music player application program 212 of device C303 in step S330 and the music player application program 212 of device D304 in step S356 plays out (spread and put/receive) while receiving the song data provided by device A301.

By performing above process, new equipment easily can be added to the second communication network 310 by communication system 300.It is to say, become easier to the second communication network adding set.

And it is possible to adding set in the case of the data in the second communication network of having performed send/receive before not stopping adding.Further, the user of the device being also not in contact with (close on position) can easily control whether to add a device to the second communication network.And it is possible to easily control to give content operation authority to the device adding the second communication network to.Therefore, communication system 300 can improve the availability of application program of the communication related between each device.

Noting, the quantity of the device of composition communication system 300 is optional.Such as, in communication system 300, in the case of adding new reception device when device A301 is to three or more reception devices distribution data, in Figure 20 A to Figure 20 C, exist multiple not in contact with (on position close) to the device about device to be added for device B302.Device A301 adds confirmation request as above about all " not in contact with the reception device of (on position close) to device to be added " execution.It is to say, each " not in contact with the reception device of (on position close) to device to be added " has and similar for the device B302 configuration in Figure 20 A to Figure 20 C, and perform similar process.

Further, in Figure 20 A to Figure 20 C, so that device D304 contacts (close on position) device B302, during thus device D304 participates in the second communication network 310.In this case, device C303 performs the above-mentioned process of device B302, and device B302 performs the above-mentioned process of device C303.

Further, participate in the second communication network 310 to device A301, device D304 by device D304 is contacted (on position close).In this case, it is " not in contact with the reception device of (on position close) to device to be added " as device B302 and C303 receiving device, thus there is the configuration similar with the situation of device B302 in example, and perform the process similar with the situation of said apparatus C303.Wherein communication system 300 is the most identical by five devices or more situation about forming.

Further, such as, to, when two device A301 and B302 form the second communication network 310, new equipment C303 can be added the second communication network 310.In this case, in addition to the process relevant with " not in contact with the reception device of (on position close) to device to be added ", the process substantially similar with above description is performed.

Then, the situation deleting the device forming the second communication network from the second communication network will be described.Such as, as shown in fig. 26, the second communication network 310 is formed by device A301 to D304.For example, device A301 operates as Communications Management Units, and device B302 to D304 is as receiving device operation, and device A301 uses the second communication to perform the stream distribution of song data about device B302 to D304.

Such as in the case of the device A301 as Communications Management Units removes fully as receiving the device D304 of device, as shown in fig. 26b, what device D304 was positioned at the second communication can be outside communication range.In this case, the second communication between its device D304 and device A301 does not continues to (arrow 313), thus deletes device D304 from the second communication network 310.But, in the case of other devices B302 with C303 and the device A301 as reception device is to communicate, device A301 continues to distribute data (arrow 311 and 312) to its device as shown in Figure 26 C.

Therefore, even if in the case of deleting device D304 from communication network 310, it is also possible to the suppression such as interim useless process stopping all stream distribution etc, and can also suppress to delete the increase of the impact of device D304.It is to say, communication system 300 can improve provides the availability of the application program of communication between each device.

This will be described below.Figure 27 A and Figure 27 B show in this case for each device content broadcast application program 211 configuration example.Figure 27 A shows that the content of device A301 broadcasts the configuration of application program 211.Figure 27 B shows that the content of device B302 and C303 broadcasts the configuration of application program 211.There is the identical reference investing it with the part similar with reference to the configuration described in Fig. 4.

As shown in fig. 27 a, broadcasting the function of application program 211 as content, device A301 has main frame delete processing unit 710, switch control unit 221, application program controlling unit 223, GUI control unit 224 and memory access processing unit 225.

Main frame delete processing unit 710 performs the delete processing of the device in the second communication network 310 by hosted (Communications Management Units).Main frame delete processing unit 710 has deletion unit 711, deletes reporting unit 712 and delete confirmation control unit 713.

Delete unit 711 and detect the reception device become from the second communication disabling (disable), and perform to process to delete its facility information and its subscriber profile information.Delete reporting unit 712 and show GUI screen, to notify that user has deleted device on monitor etc..Delete and confirm that control unit 713 notifies that user to delete the information relevant with the reception device having become to communicate from other devices.

As shown in figure 27b, broadcasting the function of application program 211 as content, device B302 has slave delete processing unit 720, switch control unit 221, application program controlling unit 223, GUI control unit 224 and memory access processing unit 225.

Slave delete processing unit 720 performs the delete processing of the device in the second communication network as slave (reception device).Slave delete processing unit 720 has deletion and confirms receive unit 721 and delete reporting unit 722.

Delete and confirm that receiving unit 721 performs the process about the deletion confirmation request supported by device A301.Delete reporting unit 722 and show GUI screen, to notify that user has deleted device on monitor etc..

Noting, the situation being functionally similar to the device B302 shown in Figure 27 B that device C303 has, as the function broadcasting application program 211 as content, therefore by the descriptions thereof are omitted.

Then, the example of handling process that will describe with reference to the flow chart in Figure 28 as adding set D304.Note, will be the most suitably with reference to Figure 29.

First, when shown in Figure 27 A, in step S401, song data is sent to device B302 to D304 (spread and put/transmit) by the music player application program 212 of device A301.On the monitor of device A301, now show that instruction is transmitting the GUI of song data.

In step S421, each of which in the music player application program 212 of device B302, the music player application program 212 of device C303 in step S441 and the music player application program 212 of device D304 in step S461 plays out (spread and put/receive) while receiving the song data distributed by device A301.The monitor of each device of device B302 to D304 showing, instruction is receiving and playing the GUI of song data.

Device D304 move to the second communication can outside communication range time, the deletion unit 711 of device A301 detects this fact, and deletes the information (such as facility information, profile information etc.) relevant with device D304.
