Technical field

The present invention relates to establish and connect and by wireless or wired transmitter that communicates, receiver, communication system, communication means, signal procedure.

Background technology

In recent years, the CCD (Charge Coupled Device) that the carrying of portable phone and digital camera, digital camera, PDA (Personal DigitalAssistant) etc. carried in the equipment is high image qualityization constantly, can absorb high-quality digitized video simply.

As the method for sharing this image, have by the service recorder medium, with lettergram mode pass on, wired connection, wireless connections etc., make image file move demonstration, or be printed on the method for passing on the paper.

Wherein, particularly, radio communication, the particularly ultrared method of use arranged as not needing physical property connection or Medium Exchange just to transmit the method for image file simply to other display unit, printing equipment, tape deck, other electronic equipments that carry equipment and personal computer etc. from carrying equipment.

As the mode of above-mentioned infrared communication, IrDA (Infrared Data Association) etc. is arranged.Have again,, for example, the prior art of following document 1～5 grade is arranged about IrDA.

Document 5:Infrared Data Association Object Exchange Protocol (OBEX) Version1.3 (Jan 3,2003)

In the past, the communication mode of IrDA or WLAN etc. for corresponding to communication flexibly, defined data link layer (linking layer also for implication identical), transport layer, application layer etc. rigorously, thereby was held consultation and repeating transmission etc. by each layer.And about the negotiation that the connection among the IrDA is in the past established, supposing has many connecting object equipment, owing to pay attention to connecting them coequally, needs many orders.In addition, at IrDA in the past, each grouping is carried out linking layer or is confirmed to be general as the repeating transmission in the MAC layer of the part of linking layer.Have again,, repeatedly send at personal computer (PC).Equipment in addition is once to send mostly.

The definition of the communication layers that these are strict although the flexibility that realizes various application is arranged, needs complicated process, and its result makes communication go up necessary expense to be increased.Particularly Fu Za connection procedure is associated with the layering of strictness, but becomes the reason of the expense increase that makes communication.In addition, the repeating transmission of each grouping is confirmed also to be of value to the dependence that improves communication, but causes the decline of communication speed.

The expense that connects is left in the basket when communicating by letter for a long time, and under the situation of the time weak point of cost, but is fatal on data transmit.Strict repeating transmission also causes the decrease in efficiency of communicating by letter.Particularly the people operates, thereby will transmit in the purposes of data in a flash, and short in the time that makes once-through operation (communication), under the situation of communication failure, preferably the people can retransmit action once more sometimes.This is the order that does not for example have the receiving channels change with the infrared remote controller of television set etc., and under the situation that television set is failure to actuate, the user indicates the situation of channel alteration order once more.

With regard to type in the past strictly carry out layering, carry out connection procedure to every layer, concerning each grouping is retransmitted, have many advantages.Therefore, according to indication of communication conditions, application, user etc., can realize communicating by letter flexibly by changeable communication process.

Below, as prior art, existing IrDA agreement is described.

Because the infrared light that uses in the infrared communication of IrDA etc. has directivity, thus under the situation that has shelter between communication equipment, can not carry out the transmission of data, but under the good situation in the visual field between communication equipment, can carry out data at a high speed and transmit.

In the IrDA standard, it is the SIR (Serial Infra Red) of Fast (FIR), 115.2kbps of Very Fast (VFIR), the 4Mbps of 16Mbps that maximum transfer rate is arranged.Product sold is the product that maximum transfer rate reaches 4Mbps on market at present.

Figure 27 is illustrated in the IrDA standard as a standard of infrared communication, the roughly process till data transfer state is set up.Here, the establishment of data transfer state, expression make the state that becomes the data that can transmit desired images or file etc. that transmits.

Main website (first station) is the station of initial searches communication counterpart, promptly is the station that data transfer state is established in request, is the station of output station search command (XIN order).In addition, secondary station (second station) is the station of accepting this request, is the station for station search command dispatching station search response (XID response) side.To become order to the request (order) at pair station from main website, on the contrary, will be called response for the response from the pair station of this order to main website.

But the XID order is to search for the order that whether has the station that can become secondary station from main website in communication distance.Which order SlotNumber represents whether to have exported.

The XID response of conduct station search response is returned at the pair station that has received the XID order, goes forward side by side and exercises the processing that main website knows that our station exists.Main website is after the XID order of having exported stated number, and output SlotNumber is 255 XID order.SlotNumber=255 represents that it is last XID order.

Then, main website uses the SNRM order to make secondary station know the set point that needs in the communications such as size of communication speed, data.Receive the pair station of this order and the set point of our station and compared, used the UA response to make main website know acceptable set point.

If it is discuss in more detail, then following such.

That is, in the IrDA standard, from 1,6,8,15, select mostly from the transmission number of the grouping of the XID of main website order.Thereby, for example as shown in figure 27, send under the situation of grouping of eight XID order, make SlotNumber be respectively from 0 to 7 from first to the 8th, after having exported 8 XID orders, to have 255 the XID order output of the SlotNumber that finishes implication, the pair station notice XID order as remote station will be finished.That is, when reaching 8, need 9 XID orders.Then, repeat after sending last grouping, through about 500 milliseconds time, the XID order that finishes till sending from the 1st to the 8th once more.Have, the transmission between the grouping is spaced apart 25～85 milliseconds again.

The secondary station when receiving the XID order is not that the XID response is returned in decision immediately, but after the grouping that has received the SlotNumber with any (value at random), returns the XID response.For example, under the situation that per 8 groupings are sent, secondary station can at random determine it is to have returned the XID response after having received the 1st grouping, still returns the XID response after having received the 8th grouping.As an example, in Figure 27, be illustrated in the situation of returning the XID response after the 4th grouping (SlotNumber=3) that received.

Have, this XID order and XID response are defined as carrying out with the such transfer rate of 9600bps according to SIR by the IrDA standard again.This transfer rate is compared very slow with the 4Mbps of the transfer rate as Frame described later.And, be not limited to immediately and have behind the XID that returns, sends from 2 to 16 during 500ms vacant etc. owing to send a plurality of XID as described above, response, so the time that needs in the transmission reception of this XID order and XID response is long.

Process through above connects the search to method, apparatus, and the connection of data link layer is ready between main website and secondary station.

After this search, in data link layer, the upper limit of speed that communicates or grouping size, the maximum time that can have transmission route, the packet count that can send continuously, the number of the virtual pulse of inserting for optical characteristics is stable when 115kbps or 9600bps, receiving from the minimum time that needs till send after to the grouping of method, apparatus to wait for, the time of under the grouping of set point only can not received situation, cutting off, the exchange that the link address that equipment room is distributed inherently etc. respond at the SNRM of the data that are used for having imported on the parameter setting of data communication needs order and UA, finish the connection of data link layer, and establish data transfer state.

After data transfer state is established, carries out the connection on upper strata by data link layer and establish.Put down in writing the order of the connection establishment of carrying out network layer, transport layer, session layer respectively among Figure 27.After they are connected establishment, all exchanged (with I frame exchange described later) as all data during from linking layer.

In the past, available 4Mbps speed communicated in IrDA high-speed communication pattern, but received waveform for sending, and had determined to carry out in 4 value PPM modes with standard.Figure 29 is that expression is about the data pulse of 4 value PPM modes and the relevant figure of data.500ns is divided into four times of every 125ns, and the information of 2 bits is represented in data pulse according to its time position.As shown in the figure, (1), (2), (3) and (4) are represented 00,01,10 and 11 information respectively.

In addition, in the standard of IrDA, determine with the frame to be that unit communicates.Figure 30 is the figure of the frame of expression IrDA standard.The frame of IrDA is made of preposition section (preamble field), startup sign, address field, control section, data segment, FCS, end mark.Among above-mentioned section, preposition section is used to be created on the receive clock that receiving terminal uses in receiving circuit.And in FCS, include the error detecting code or the error correcting code that are used for error detection occurs.

Based on this basic frame structure, determine various command in fact as shown in Figure 28.

In addition, in frame, I (Information) frame that the information that is useful on transmits, S (Supervisory) frame of the supervision that is used for communicating by letter and U (Unnumbered) frame of connection that is used to communicate by letter or cut-out etc.The packets of information that is used for discerning these I, S, U frame is contained in above-mentioned control section.

Usually, the data that are transmitted are can not be with the situation of 1 frame transmission, so send after being split into a plurality of I frames mostly.The I frame has the data that will transmit in data segment, the serial number of the inspection by being useful on data extract is realized the communication that reliability is high.The S frame becomes the structure of the data segment that does not keep data, be used to transmission receive be ready to complete, busy condition, re-send request may etc.The U frame does not have the such number of I frame, so be called as non-number frame, is used to the report of setting, response or the abnormality of communication pattern, the establishment or the cut-out of data link.

Figure 31 is the precedence diagram that is used for illustrating the general process of above-mentioned communication mode.The establishment of data transfer state is sought for the B station in the A station, and sends the SNRM frame.The B that has received it stands in and replys the DM frame under the situation about can not communicate by letter, and replys the UA frame that means promise under situation about can communicate by letter.SNRM frame, DM frame, UA frame all are the U frames.The data transfer state at two stations was established when B replied the UA frame in the station, can carry out data and transmit.

Here, expression has sent the data conditions that is split into a plurality of I frames from the A station to the B station.At first, the A station sends the I frame of initial Frame having been given number ' 0 '.The B station that received it will have been given the response frame (data transmission requests frame) of ' 0 ' Next ' 1 ' number and replied, and transmit the meaning of ' sending the 1st data '.This response frame is the S frame of so-called RR frame.The I frame that A has confirmed at the station will to comprise behind the response frame at B station the 1st divided data sends.By this process only being repeated necessary number of times, can improve the communication precision of a plurality of I frame traffics.

In addition, also can be that the A station connects the load mode that a plurality of I frames send.In this case, when the transmission of all I frames finished, A station desire finished to communicate to connect, and for the B station, was the DISC frame transmission of the cut-out request of U frame with expression.Then, cut off when having replied the UA frame of the U frame that expression promises to undertake at the B station, communicate to connect and be cut off.And occur in station therein under the situation of uncomfortable situation of communication abnormality etc., also send the request of cut-out and cut off and communicate to connect by this station.

At IrDA, carry out radio communication by above such method, but on the characteristic of light, reach the angle more than certain certain angle (in the standard at IrDA for ± 15 °) or reach under the situation of the distance more than certain certain distance (in IrDA be 20cm or 1m according to standard) at the infrared interface between the communication equipment, even have the high communication means of reliability, but communication also may be from can not carry out midway.

Thereby, according to the IrDA mode, in station search or information exchange, need the time, in transmitting, data carry out the affirmation of the transmission reception of data between transmitter and the receiver continually, so transmission efficiency descends.Its result at the infrared communication of IrDA mode, has the delivery time long, and communication may be from the high problem of probability that can not carry out midway.

Have again, as file is sent to other devices with wireless mode, and the method that shows, on March 25th, 2004), the spy opened the 2000-69403 communique (open day: on March 3rd, 2000), the spy opened the 2001-83948 communique (open day: March 31 calendar year 2001) for example be recorded in Japanese publication communique ' special table 2004-509527 communique (open day:, even but these modes, under the situation of using infrared ray to communicate, produce same drawback.

Summary of the invention

Secondly, controller 13 is according to the transmission request from CPU11, and the controller to the transmission that transmits data is controlled comprises: control assembly 131, packet generate parts 132 and error detection correction code optional feature 133.

When control assembly 131 receives the transmission request from CPU11, read the transmission data from memory 12, the transmission data that read out are sent to packet generate parts 132, grouping generates a plurality of packets of parts 132 generations to data simultaneously.At this moment, the block length and the class interval of 132 generations of 131 pairs of data groupings of control assembly generation parts are controlled.Have, control assembly 131 is controlled at block length below the maximum packet that can be obtained by the data volume that error detection correction code optional feature described later 133 detects again.

In addition, control assembly 131 detects all the corresponding packets of the transmission data with reading from memory 12 that send from transmit block 14, and the transmission end notification that expression is transmitted the transmission end of data is sent to CPU11.

Packet generates parts 132 will be cut apart from the transmission data that control assembly 131 receives, thereby generate a plurality of packets.At this moment, packet generates parts 132 and will transmit data and cut apart, becoming the length that receives from control assembly 131, and generation partition data (1) ... (N).Then, packet generates parts 132 and generates the packet that each partition data is comprised as information.That is, packet generate parts 132 generate the packet (1) that comprised partition data (1) ..., comprised the packet (N) of partition data (N).Have, packet generates controlled parts 131 controls of transfer rate of the packet of parts 132 generations again.

A plurality of groupings that packet generation parts 132 will generate are sent to error-detection error-correction sign indicating number optional feature 133.At this moment, packet generation parts 132 make the class interval of the time interval for receiving from control assembly 131 between each packet.

Here, as shown in figure 30, each packet includes preposition section, starts sign, address field, control section, data segment, FCS and stops sign.

Error-detection error-correction sign indicating number optional feature 133 generates the packet that parts 132 generate for packet, after additional error detecting code or the error correcting code, is sent to the transmit block 14 of back level.Error-detection error-correction sign indicating number optional feature 133 is contained among the interior above-mentioned FCS of packet error detecting code or error correcting code.

Have, error detecting code (reference literature 2) for example is the touring sign indicating number of CRC (Cyclic Redundancy Check) sign indicating number etc. again, and error correcting code for example is the BCH code of odd-even check sign indicating number, Hamming code, Reed-Solomon sign indicating number etc. etc.Have, the CRC sign indicating number has certain length of determining, is restricted to the data volume that can detect mistake according to its length again.Specifically, the CRC sign indicating number has 16 bits, 32 length than top grade, according to its length, if for example be 16 bits, then can 100% detects the mistake of 1 bit in the data till 2048 bytes.

Transmit block 14 is by the infrared communication path, and a plurality of groupings time interval in accordance with regulations that slave controller 13 is received sends to the outside.

Secondly, the electronic equipment of present embodiment comprises the receiving equipment that is used to carry out Data Receiving, about this receiving equipment 2, describes according to Fig. 8.

As shown in the drawing, receiving equipment 2 comprises: CPU21, memory 22, controller 23, CDR24, as the receiving-member 25 of wireless communication interface.

Receiving-member 25 receive the grouping that sends from transmitting apparatus 1, and the grouping that will receive is sent to CDR24 by the infrared communication path.

CDR24 extracts (recovery) clock signal and data-signal according to the grouping that receives from received signal.CDR24 is sent to controller 23 with clock signal and the data-signal that restores.

Controller 23 is according to the grouping that receives from CDR24, the control and treatment of stipulating.Controller 23 comprises: control assembly 231, packet transaction parts 232 and error detection/correction circuit 233.

Packet transaction parts 232 receive the grouping of being restored by CDR24, detect to start sign and stop sign from the grouping that receives.Then, packet transaction parts 232 extract data segment and FCS part.That is, packet transaction parts 232 extract the information that comprises in the data segment of the grouping that receiving-members 25 receive and for the error detecting code or the error correcting code of this information.Packet transaction parts 232 are sent to control assembly 231 and error detection/correction circuit 233 with the information that extracts and error detecting code or error correcting code.

For example, when packet transaction parts 232 receive packets, extract the data and error detecting code or the error correcting code that comprise in this packet, and the data that extract and error detecting code or error correcting code are sent to control assembly 231 and error detection/correction circuit 233.

Error detection/correction circuit 233 carries out error detection occurs or error correction for the information that receives, and its result is sent to control assembly 231.

Control assembly 231 carries out predetermined process according to the result who transmits from error detection/correction circuit 233.That is, be illustrated in the partition data under the situation of be free from mistakes (error) in the result from error detection/correction circuit 233, control assembly 231 receives end with this writing data into memory 22 to the CPU21 notice.On the other hand, be illustrated under the situation that mistake is arranged in the data in the result from error detection/correction circuit 233, control assembly 231 discarded these data have the reception mistake to the CPU21 notice.

The data that memory 22 storage receiving-members 25 receive, data are written into by control assembly 231.In addition, in present embodiment, have storage and be used to realize the program of various communication functions and the function as storage device of data.Various communication functions and transmitting apparatus 1 are same, are at least a and communication functions 9 at least a and communication function 6 or the above-mentioned communication function 7,8 at least a and communication function 3 in the above-mentioned communication function 1,2 or the above-mentioned communication function 4,5.These communication functions 3,6,9 are the IrDA agreements as described above.

CPU21 is presented on the not shown display unit image corresponding with for example view data that generates according to the data that are written in the memory 22.

Below, for the data transfer process in above-mentioned transmitting apparatus 1 and the receiving equipment 2, describe with reference to the precedence diagram shown in Fig. 1 (a) and Fig. 1 (b).

At first, between transmitting apparatus 1 and receiving equipment 2, carry out under the situation of infrared communication, in IrDA agreement, shown in Fig. 1 (a), carry out packet switching as the XID command of station search command as communication function 3.

But, on the characteristic of infrared communication,, be in the scope that user's eyes can see as the other side's who communicates with the transmitting apparatus of holding on hand 1 receiving equipment 2.

Therefore, in present embodiment, shown in Fig. 1 (b), replacement is as the exchange of the grouping of the XID command of station search command, the equipment that receives by User Recognition also carries out transmit operation, for example, can determine and the electronic equipment that communicates as the transmitting apparatus 1 that carries equipment method, apparatus.Promptly, when beginning communication by use will to the search of method, apparatus and with the communication function 1 that the exchange that is connected essential order of method, apparatus is carried out with same grouping, the packet switching of station search command can be omitted, the time that needs in the communication of file can be shortened.Specifically, the search of the station of IrDA agreement is generally about 3～4 seconds the required time, thus on can communication with file the required whole time shorten this part time.

On the other hand, when in the IrDA agreement, beginning to communicate by letter, as Fig. 1 (a) or shown in Figure 27, for example in the enterprising various communications of being about to communication that data send to receive etc. of the twocouese of IrCOMM or IrFM etc., use the SNRM command to exchange as to the opening circuit of size, minimum commutating period and the link of the size of for example spendable communication speed of the ability of method, apparatus, maximum commutating period, per 1 frame, window size, additional BOF/threshold time etc.

But, as present embodiment, under the situation that only transmits file, can be predetermined and be used to transmit the required parameter of file.

Specifically, be predetermined the data volume of per 1 frame and maximum/minimum commutating period etc.Thus, the output of main website end only records and narrates that illustrated will be from the bind command of the parameter of predetermined value change, under the situation that pair station end is not is not recorded and narrated, be identified as predetermined value, check and return with the response of having recorded and narrated the parameter of consulting with the parameter of our station.Even at the pair station, if identical with predetermined value, it is also passable then not record and narrate this parameter in response.Under the situation that main website is not is not recorded and narrated in the response of its reception, being identified as is predetermined value, thereby available this parameter communicates.

In addition, for example, the main website end will have been imported the bind command output of the parameter of the response that does not need secondary station end.The pair that the has received bind command not return command response of standing receives the preparation of data according to the parameter of this explanation, then, and the main website dateout.Thus, can further shorten process.

In addition,, also can adopt all projects that pre-determines, not send the method that connects grouping and begin data communication from main website for further shortening process.In the IrDA agreement, in this information exchange etc., carry out for several times～tens of times packet switchinges, need about 1～2 second time.By omitting the facility information that will exchange, can carry out 1 or 2 packet switching, the time of needs can be suppressed to about 100ms.

Even without the parameter that is predetermined application, by be connected grouping and side by side transmit application packet and also can realize.At Figure 11 (a), top parameter is transmitted by data link layer is additional in the back that is illustrated in the connection parameter of data link layer, thereby can be connected to the example of high level (network layer, transport layer, session layer etc.) with a reciprocal connection.The example that connects grouping is described among Figure 11 (c).

Like this, the facility information that omission will exchange, promptly when the communication beginning, only exchange minimal connection parameter and whether need response, other parameter is used the value of predetermined fixed, perhaps by importing the high-rise parameter that is connected simultaneously with the connection request of data link layer, shown in Fig. 1 (b), can further shorten the whole time required in the file communication.

In addition, in the IrDA agreement, shown in Fig. 9 (a), after main website has transmitted Frame (I frame), return action with this frame corresponding response by the pair station, with the integrality (send and receive the data that are free from mistakes) that keeps data.

But, under situation as carrying equipment from the communication of handheld device, even in any case the agreement that all can guarantee integrality has been installed, but reach certain angle more than certain in the angle of equipment room, distance reach certain certain above apart from the time, the communication difficulty that just becomes.Its result, error data increases, and re-send request may is carried out continually to main website in secondary station, and main website responds this request and retransmits continually.Its result, the required time of packet switching increases.

On the contrary, in present embodiment, adopt communication function 4 or communication function 5 and do not carry out the retransmission process of data, or reduce the number of times of re-send request may.

Promptly, transmitted the result of data, by record in the electronic equipment or demonstration, under the situation of the communication of available sender in this place---user's eyes identification, the angle of close receiver or change transmitter etc., user self can improve communications status, so the amount that can reduce errors and handle by this improvement.

Like this,, but the re-send request may of data is concentrated the communication function 4,5 that sends after having carried out a plurality of Data Receiving, shown in Fig. 9 (b), also can shorten the time that needs in the file communication by adopting even in the data in communication mistake takes place.

The retransmission process of expression IrDA among Figure 32 (a).Sent data in IrDA in the past after, receiver returns the response (LAP) of lower floor, and transmitter is transferred the possession of transmission route once more (RR) to receiver then, after receiver has been replied the response of high-rise (OBEX), carries out the order that next data are sent then.

Under the situation that mistake has taken place, notify this situation, carry out the transmission again of this grouping by the response of lower floor.

The normal system action of the present invention that Figure 32 (b) expression is used with communication function 4 or communication function 7, the action during Figure 32 (c) expression generation mistake of the present invention.Transmitter is to the packet allocation serial number, gives transmission route to receiver after having sent the grouping of concentrating that has determined number, and whether no problem receiver carried out data inquiry.

At receiver is under the situation of OK (not detecting mistake), with the advisory transmitter that has normally received, and detecting under the amiss situation, the later data division of the grouping that can not receive is ignored, and notice is in the transfer part of only confirming transmission route and received the packet numbers that can not receive behind the transfer of transmission route.Mistake in this case is meant that a part of data that detect in the grouping by CRC etc. produce the situation of loss, or skips number in the serial number.

Transmitter carries out sending from next grouping under the situation that has received OK.Under the situation that has received the notice (packet numbers) that mistake is arranged, send the data that just sent once more from this packet numbers.

By taking above such structure, can carry out the high communication of efficient with filling between grouping.

The normal system action of the present invention that Figure 33 (a) expression is used with communication function 5 or 8, the action during Figure 33 (b) expression generation mistake of the present invention.Transmitter sends all data in a continuous manner to the packet allocation sequence numbering.

Receiver only confirms whether mistake is arranged, and is identified as normal reception in receiver after having received all data under the situation about normally receiving, and carries out next action.Next action in this case for example has the data that will receive to show or prints or preserve.

Under the amiss situation of detection, in receiver, be identified as and fail normally to receive, and carry out next action.Next action in this case is to become the indication of the situation that makes the user know failure or next reception wait state.

As present embodiment, by the amount that reduces errors and handle, can reduce the number of packet and respond packet, the time that minimizing needs in exchange, produce the load of CPU hardly, even, under the situation of having used FIR, also can reach the effective speed of 3.5～3.8Mbps so carry equipment.For example, if the file of the 150kByte that is compressed by JPEG about 800,000 pixels (XGA:1024 * 768), effective speed needs 0.6 second as 2Mbps in the IrDA agreement, as 1Mbps, needs 1.2 seconds.But, as present embodiment, if thereby the treating capacity of the rate that reduces errors reaches the effective speed of 3.8Mbps, then become 0.31 second, if reach the effective speed of 3.5Mbps, then become 0.35 second.Its result can communicate below half in the pact of IrDA, can shorten the time that needs in the file communication.

In addition, by having adopted the communication function 7,8 that uses above-mentioned two communication function both sides, shown in Figure 10 (b) or Figure 10 (c), can further shorten the time that needs in the communication of the file in the IrDA agreement shown in Figure 10 (a).

For example, under the situation of having used above-mentioned two communication functions, when the situation of video file of the relevant above-mentioned 150kByte of transmission is described, in IrDA, need

Search (3～4 seconds)+information exchange (1～2 second)+data of standing send the time of (0.6～1.2 second)=total (4.6～7.2 seconds), and in these cases, become

(search+information exchange of standing) (0.1 second)+data communication (0.31～0.35 second)=total (0.41～0.45 second) becomes 1/10th to 1/17th call duration time.

When call duration time is 5 seconds left and right sides, the user will carry equipment towards other direction in communication, be considered to communicate by letter and will abandon, if but call duration time is about 0.5 second, then towards carrying equipment, sign off during sending processing is very easy to, communicates by letter easily so become.

Like this, data communication system and data transferring method thereof in present embodiment comprise: carry equipment, comprise the recording medium (memory 12,22) of transmit block 14, receiving-member 25 and preservation data as wireless communication interface; And electronic equipment, comprise transmit block 24, receiving-member 25 as wireless communication interface, and record data.And, carry equipment and above-mentioned electronic equipment comprises respectively: storage device (memory 12,22), storing communication function 1,2, the search when the communication beginning of this communication function connects necessary parameter simultaneously and exchanges method, apparatus; And as the controller 13,23 of communication control unit, communication is controlled, these two controllers 13,23 use communication functions 1,2 to transmit data carrying between equipment and the electronic equipment.

Promptly, as the method that shortens call duration time, use communication function 1,2 to carry communicating by letter of equipment and electronic equipment, communication function 1,2 is not exported the station search command (being the XID order in IrDA) that only carries out the search of method, apparatus when the communication beginning, and will possess search and the grouping output that has two functions of order that are connected necessary parameter.

Its result, owing to do not use station search command and connection procedure, so can shorten the delivery time of data.Therefore, can reduce, or distance reaches the probability of the communication failure that certain certain above distance causes because the angle between the equipment reaches certain certain above angle.

In addition, data communication system and data transferring method thereof in present embodiment, necessary parameter should be used the value of predetermined fixed in the connection that exchanges with communication function 1,2, or sets initial value, in connecting grouping even comprise and transmit high-rise connection parameter or order.

Its result goes up necessary parameter by using predefined fixed value as connecting, and perhaps uses the parameter or the order that connect the high level that comprises in the grouping at one, can further shorten the connect hours.Therefore, can reduce, or distance reaches the probability of the communication failure that certain certain above distance causes because the angle between the equipment reaches certain certain above angle.

Here said initial value for example is meant in data link layer

Baud?Rate：4Mbps，115kbps，9600bps

(communication speed)

Maximum Turn Around Time:1s[transmitter (master)], 100ms[receiver (pair)]

(maximum time that can have transmission route)

Data?Size：2048bytes

(can be input to a maximum length in the grouping)

Window?Size：1

(packet count that can send continuously among the existing IrDA)

Additional?BOFs：0

(number of the virtual pulse of inserting for optical characteristics is stable when 115kbps or 9600bps)

Minimum?Turn?Around?Time：0.5ms

(after having received, the time that subsistence level is waited for till extremely sending) from grouping to method, apparatus

Link?Disconnect/Threshold?Time：1seconds

(only not receiving the time that to cut off under the situation of grouping) with set point

Minimum?Packet?Interval：100μs

(time between grouping) such data, high-rise order for example refer to the response of the Connect order of OBEX and its success etc.

In addition, data communication system and data thereof in present embodiment transmit, carry equipment and electronic equipment comprises respectively: as the memory 12,22 of the storage device of having stored the program that is used to realize communication function 4,5 and data, even the retransmission process that mistake is not also carried out data has taken place in this communication function in data in communication, handle and many continuous data are sent the mistake of carrying out once, number of processes reduces errors; And as the controller 13,23 of communication control unit, communication is controlled, these controllers 13,23 use communication function 4,5 to transmit data carrying between equipment and the electronic equipment.

That is,, use the communication function 4,5 of the number of times minimizing that mistake is handled to carry communicating by letter of equipment and electronic equipment as the method that shortens call duration time.In addition, about the answer of error message, return with a grouping.

Its result can omit the frame and the respond packet that are used to carry out retransmission process and frequently alternately exchange, in addition, can alleviate the disposal ability of the CPU that needs for retransmission process, and, can shorten delivery time of data.Therefore, can reduce because the angle between the equipment reaches certain certain above angle, or the probability of the communication failure that causes apart from reaching certain certain above distance.

In addition, data communication system and data thereof in present embodiment transmit, carry equipment and electronic equipment comprises respectively: as the memory 12,22 of the storage device of having stored the program that is used to realize communication function 7 or communication function 8 and data, communication function 7 has both functions of above-mentioned communication function 1 and communication function 4, and communication function 8 has both functions of communication function 2 and communication function 5; And as the controller 13,23 of communication control unit, communication is controlled, these controllers 13,23 use communication function 7,8 to transmit data carrying between equipment and the electronic equipment.

Its result has the communication function 7 of both features of communication function 1 and communication function 4 or has communication function 2 and the communication function 8 of both features of communication function 5 by use, can further shorten the delivery time of data.Therefore, can reduce because the angle between the equipment reaches certain certain above angle, or the probability of the communication failure that causes apart from reaching certain certain above distance.

In addition, in the data communication system and the data transmission thereof of present embodiment, radio communication is infrared ray (IR) communication.

That is,, as described above, the IrDA standard is arranged as having used ultrared data to transmit.Therefore,, can reduce because the angle between the equipment reaches certain certain above angle for example for the equipment that has adopted the load mode that meets the IrDA standard, or the probability of the communication failure that causes apart from reaching certain certain above distance.

(1) communication layers

Figure 34 is the schematic diagram of corresponding relation of the layering of the layering of expression OSI7 hierarchical mode, IrDA and communication system of the present invention.

In present embodiment, structure and action about the transmitter and the receiver of communication system of the present invention explain according to the OSI7 layer model.Here, the OSI7 layer model is also referred to as so-called ' OSI basic reference model ', ' OSI hierarchical mode '.

At the OSI7 layer model, in order to realize the data communication between different machines, the communication function that computer should have is divided into 7 layers, and definition has the functional module of standard to each layer.

Specifically, the 1st layer (physical layer) takes on electric conversion or the mechanical operation that is used for data are outputed to communication line.The 2nd layer (data link layer) guarantees the communication path of physical property, and flows through the error detection occurs etc. of the data of communication path.The 3rd layer (network layer) communicates the selection in path or the management of the address in the communication path.The 4th layer (transport layer) carries out data compression or error correction, repeating transmission control etc.The 5th layer (session layer) is used for carrying out between the signal procedure establishment or the releasing of the virtual route (connection) that the transmission of data receives.The 6th layer (presentation layer) will be the clear easily form of user from the 5th layer of data conversion of obtaining, maybe will be from the 7th layer of data conversion that sends for being fit to the form of communication.The 7th layer (application layer) will utilize the various services of data communication to offer individual or other programs.

Each communication layers of the communication system of present embodiment also has and the equal function of the corresponding layering of above-mentioned OSI7 layer model.But as shown in figure 34, it is one that above-mentioned communication system makes session layer and presentation layer, becomes 6 layers structure.

The present invention can be widely used in that transmitter is established being connected of a plurality of communication layers with receiver and the communication system that communicates.That is, communication function cut apart impassable according to the OSI7 layer model yet.In addition, the number of communication layers just can at random be selected so long as the communication layers that will connect is a plurality of.

In addition, the present invention shortens the time that needs by the connection request of a plurality of communication layers is concentrated on connecting, so even under the situation that communication path cuts off, it is also easy to connect again.Therefore, all be effective in the present invention's, other radio communications of comprising Bluetooth wireless and the wire communication at IEEE802.11.

In addition, in present embodiment, the example that relevant connection with all communication layers connects with communication mode has been described, but has the invention is not restricted to this.For example, after having connected a communication layers, it is also passable to connect remaining a plurality of communication layers.In addition, the connection of a communication layers also can be undertaken by repeatedly communicating by letter.For example, need carry out under the situation of twice communication, the connection of data link layer and network layer the 1st time is connected to concentrate be a connection request in the connection of network layer, the 2nd time of network layer connected and transport layer to be connected concentrated be that a connection request is just passable.

In present embodiment, for convenience of explanation, describe according to the IrSimple of an application examples of the present invention.But the present invention is not limited to IrSimple.Have, IrSimple has improved the part of functions of IrDA in the past again.

SMP (S) receives the connection request function from OBEX (S), and becomes the reception holding state.And SMP (S) is under the situation that has received the connection notification function from low layer (SMP (S)), from the data of function, extract the parameter of SMP (P) generation of transmitter, generation is for the parameter of the response of this parameter, and after the connection request function of the data that will add the parameter of having removed SMP (P) from the data of above-mentioned function is sent to OBEX (S), wait for connection response function from OBEX (S).And SMP (S) is under situation about having received from the connection response function of OBEX (S), parameter for LMP (S) additional above-mentioned response in the data of the connection response function of OBEX (S), thereby LMP (S) is produced the connection response function, and finish the negotiation of SMP layer.

LMP (S) receives the connection request function from SMP (S), and becomes the reception holding state.And LMP (S) is under the situation that has received the connection notification function from low layer (LAP (S)), from the data of function, extract the parameter of LMP (P) generation of transmitter, generation is for the response parameter of this parameter, and after the connection request function of the data that will add the parameter of having removed LMP (P) from the data of above-mentioned function is sent to SMP (S), wait for connection response function from SMP (S).And LMP (S) is under situation about having received from the connection response function of SMP (S), parameter for LAP (S) additional above-mentioned response on the data of the connection response function of SMP (S), thereby LAP (S) is produced the connection response function, and finish the negotiation of LMP layer.

Have again, define LSAP (Link Service Access Point) for the management logic port usually.Thereby, carrying out not needing to use LMP under the situation of a connection in mode one to one.In this case, the value that will not connect in LSAP is used as fixed value.Therefore, do not need the connection parameter exchange of LMP.

LAP (S) receives the connection request function from LMP (S), becomes the reception holding state.And LAP (S) is under the situation that has received the SNRM order from physical layer, from the data of SNRM order, extract the parameter of LAP (P) generation of transmitter, and after the connection request function of the data that will add the parameter of having removed LMP (P) from the data of SNRM order is sent to LMP (S), generation is for the response parameter of this parameter, and wait is from the connection response function of LMP (S).And LAP (S) is under situation about having received from the connection response function of LMP (S), additional above-mentioned response parameter in the data of the connection response function of LMP (S), thereby to physical layer output UA frame, and finish the negotiation of LAP layer.

Present embodiment (not having response)

Figure 41 is the precedence diagram of the order of connection of expression present embodiment (not having response).And the key diagram of the data structure of the communication data of Figure 40 (a) when being the order of connection of expression present embodiment (do not have response).

As shown in figure 41, present embodiment (not having response), transmitter, receiver all connect preparation.Then, when transmitter is transferred to low layer in the request former state with high level, send as a grouping (SNRM).Then, transmitter was finished as connection in the moment that has sent the SNRM grouping, from LAP (P) to high level give notice (Connect.confirm).On the other hand, receiver receives the SNRM grouping, and former state is carried out and can in the moment to OBEX (S) notice connection be finished to the notice of high level connection.

At this moment the order in transmitter, the receiver is following like that.

Each communication layers of relevant transmitter at first, is described.

OBEX (P) promptly is inserted into the connection request order in the data to low layer (SMP (P)) and produces connection request function (Primitive) under the situation that the connection request that comes self-application arrives.And OBEX (P) makes to connect and finishes under the situation that has received connection affirmation function from SMP (P).

SMP (P) receives the connection request function from OBEX (P), required parameter on the communicating by letter of the SMP (S) of additional and receiver in the data of the connection request function of OBEX (P) promptly, thereby to low layer (LMP (P)) generation connection request function.And SMP (P) is receiving the moment that connects the affirmation function from LMP (P), as with the completed negotiation of parameter that sends, finishes the negotiation of SMP layer.In addition, SMP this moment (P) sends to connect for OBEX (P) and confirms function.

LMP (P) receives the connection request function from SMP (P), required parameter on the communicating by letter of the LMP (S) of additional and receiver in the data of the connection request function of SMP (P) promptly, thereby to low layer (LAP (P)) generation connection request function.And LAM (P) is receiving the moment that connects the affirmation function from LAP (P), as with the completed negotiation of parameter that sends, finishes the negotiation of LMP layer.In addition, LMP this moment (P) sends to connect for SMP (P) and confirms function.

Have again, define LSAP (Link Service Access Point) for the management logic port usually.Thereby, carrying out not needing to use LMP under the situation of a connection in mode one to one.In this case, the value that will not connect in LSAP is used as fixed value.Therefore, do not need the connection parameter exchange of LMP.

LAP (P) receives the connection request function from LMP (P), the parameter that in the data of the connection request function of LMP (P), needs on the communicating by letter of the LAP (S) of additional and receiver promptly, thus the physical layer output SNRM of receiver is ordered.And LAP (P) is in the moment of having exported the SNRM order, as the completed negotiation of parameter with transmission, with the negotiation end of LAP layer.In addition, at this moment, LAP (P) sends to connect to LMP (P) and confirms function.

Each communication layers of relevant receiver then, is described.

OBEX (S) receives the connection request function from using, and becomes the reception holding state.And OBEX (S) is receiving under the situation of connection notification function (Indication) from low layer (SMP (S)), confirms the OBEX bind command from these data, if no problem, then connection is finished.

SMP (S) receives the connection request function from OBEX (S), becomes the reception holding state.And SMP (S) is receiving from low layer (SMP (S)) under the situation that connects notification function, extracts the parameter that the SMP (P) of transmitter generates from the data of function, uses this parameter and finishes negotiation.Then, SMP (S) the connection request function that will add the data of the parameter of having removed SMP (P) from the data of above-mentioned function is sent to OBEX (S).

LMP (S) receives the connection request function from SMP (S), becomes the reception holding state.And LMP (S) is receiving from low layer (LAP (S)) under the situation that connects notification function, extracts the parameter that the LMP (P) of transmitter generates from the data of function, uses this parameter and finishes negotiation.Then, LMP (S) the connection request function that will add the data of the parameter of having removed LMP (P) from the data of above-mentioned function is sent to SMP (S).

Have again, define LSAP (Link Service Access Point) for the management logic port usually.Thereby, carrying out not needing to use LMP under the situation of a connection in mode one to one.In this case, the value that will not connect in LSAP is used as fixed value.Therefore, do not need the connection parameter exchange of LMP.

LAP (S) receives the connection request function from LMP (S), becomes the reception holding state.And LAP (S) is under the situation that has received the SNRM order from physical layer, extracts the parameter that the LAP (P) of transmitter generates from the data of SNRM order, uses this parameter and finishes negotiation.Then, LAP (S) the connection request function that will add the data of the parameter of having removed LAP (P) from the data of above-mentioned function is sent to LMP (S).

(3-2) exchanges data order

IrDA in the past

Figure 42 is a precedence diagram of representing the exchanges data order of IrDA in the past.Have again, the data structure of the communication data the during order of connection of IrDA in the past shown in Figure 35 (a) like that.

As shown in figure 42, at IrDA in the past, transmitter produces the PUT order, and this order is till flowing through low layer and be used as the I frame and send to transmitter.Receiver receives this order, and the indication of data is sent to high level, and the credit (credit) that TTP (S) will represent to receive several groupings turns back to transmitter.Have, the TTP layer is taken on current control again.

Transmitter will be sent to TTP (P) from the credit that receiver receives.At this moment, LAP (P) sends RR (transmission route transfer) grouping.Then, receiver is exported the response that OBEX (S) produces after having received the RR grouping as the I frame.

Transmitter receives the response of OBEX (S), and produces next PUT order.

Present embodiment (response is arranged)

Figure 43 is the precedence diagram of the exchanges data order of expression present embodiment (response is arranged).And Figure 44 is the key diagram of data structure of communication data in exchanges data when order of expression present embodiment (response is arranged).

As shown in figure 43, present embodiment (response is arranged), transmitter produces the PUT order, and this order is used as the output of UI frame till being sent to low layer.

On the other hand, receiver obtains data, and high level is given notice.At this moment, at SMP (S), for the OBEX (S) of high level, notice continues (status=truncated) with data.

Transmitter sends confirming that sign that whether data neatly arrive is connected after the grouping that has sent certain fixed number.Receive this sign, receiver detects SMP (S) and is free from mistakes, and is having under the situation of mistake, will produce the number notifying transmitter of mistake.

If be free from mistakes, the then next grouping of transmitter output, and if mistake arranged, then transmitter resends the grouping after the grouping of mistake.

Transmitter is that the sign of last data is connected and sent with expression when having reached last data.To this, if SMP (S) should indicate connection, then receiver is to OBEX (S) notification data complete neat (status=OK), and waits for the response of OBEX (S).Then, when having produced the response of OBEX (S), these data are sent to low layer, export as the UI frame.

If the response that receives is Success, then transmitter carries out normal termination.

The transmitter of this moment, the order in the receiver are as described below.

At transmitter, OBEX (P) sends function with the PUT order as data to low layer and exports.Wherein, OBEX (P) under the situation that available SMP (P) sends, exports Next Command in the response (Continue returns under the normal situation) that need not order except the PUT PUT Final (last PUT) order.Under the situation of the order except PUT Final order or PUT order, wait for data notification function from low layer, observe the interior response of these data and the finish command.

Here, data transmission function is the function (Data Request) that the low layer request msg is sent.And the data notification function is to know the function (Data Indicate) that has received data from low layer.

At receiver, OBEX (S) receives the data notification function from low layer, and receives data.Wherein, OBEX (S) does not return response for the PUT order except PUT Final order, under the situation of the order except PUT Final order or PUT order, sends function and returns response as data.

Here, the data transmission function of relevant high level shared in transmitter, receiver and low layer and the head in the data notification function etc. are described.

When SMP receives data transmission function from OBEX, for LMP, (a) size of data hour the size that can send with LPM (size) sends function than data in, these data are divided into the size that LMP can send, when (b) size of data is big the size that can send with LMP sends function than data in, several data are carried out combination, thereby form the following bigger data of size that can send.In addition, SMP generates the SMP head, and this head has added serial number, to the independent variable of the last data of independent variable, the expression of the other side's equipment query data receiving state, expression the SMP of method, apparatus needed whether normal independent variable etc. of the independent variable of the response of OBEX, data that expression receives.Then, LMP is sent data sends function, this function added with this SMP head be attached to carried out above-mentioned cut apart or the data of combination in data.

And, when SMP receives the data notification function from LMP, extract the SMP head the data in this function out, and confirm whether normally whether serial number (that is, do not omitted and arrival sequentially).Then, under normal situation, OBEX is sent the data notification function.At this moment, the data notification function can be by each the data notification function output from low layer, also the data from the data notification function of several low layers can be merged output.

The SMP of transmitter (P) will be the data transmission function to LMP (P) from the data transmission functional transformation of OBEX (P), thereby send the data transmission function of certain size of fixing a number of regulation.Then, it is that True sends data transmission function that SMP (P) makes the independent variable to receiver data query accepting state, waits for the data notification function of LMP (P) then.

SMP (P) is to resolving from the SMP head in the data notification function of LMP (S), under the data situation whether normal independent variable is normally received that expression receives, as finishing the preparation that sends next data, becoming can be to the state of OBEX (P) transmission.That is, under this state, can obtain data from OBEX (P).

On the contrary, the SMP head of the data notification function that obtains from LMP (S) is being resolved and illustrated under the data situation whether normal independent variable is not normally received that expression receives, SMP (P) produces from notified once more to the data that can not normally receive send independent variable from the function to the other side's equipment query data receiving state, is till the data of True send function until this independent variable.SMP (P) repeats to retransmit and till the data that all data send function are informed to receiver, or repeats certain stipulated number and retransmit.

And, having received from OBEX (P) is that the independent variable of last data is that the data of True send under the situation of function, SMP (P) will add data to LMP (P) that these data send the final data of function and send function and send, and the independent variable that this function makes these data of expression send the response of the OBEX (S) that independent variable that function is a final data or expression need receiver is True.

On the contrary, the SMP of receiver (S) is when LMP (S) has received the data notification function, in the last data of expression or to need the independent variable of response of the OBEX (S) of receiver be under the situation of True, OBEX (S) is sent the data notification function, and this function has added the data except the head of SMP (S).

In addition, SMP (S) is receiving from LMP (S) under the situation of data notification function, according to the data in this data notification function the SMP head is resolved, and the number of affirmation order.If till receiving the head that independent variable to receiver data query accepting state is True, all can not normally receive, then SMP (S) generates and to be used to represent normally to receive the whether SMP head of normal independent variable of data that expression receives, and this head is sent data as data to LMP (S) sends function.

On the other hand, SMP (S) is detecting under the situation of failing normally to receive, and storage is predicted to be the number of the SMP head of failing normally to receive.For example, received at 0,1,2,3,5 o'clock, should not receive under 4 the situation for 4 at the 5th, being predicted to be the number that can not normally receive is 4.Thereby afterwards, whether the independent variable that SMP (S) only investigates the receiver data query accepting state of SMP head is True, and stops OBEX (S) dateout notification function.

SMP (S) is receiving under the situation of data notification function that independent variable to receiver data query accepting state is True, generation be used for representing normally receiving data that expression receives whether normal independent variable, and the number of the SMP head that can not normally receive be inserted into the SMP head of the field of addition sequence number, this head is sent data as data to LMP (S) sends function.

And be under the situation of data notification function of True at the independent variable of the response that has received independent variable that expression is last data or the OBEX (S) that expression needs receiver, after OBEX (S) had been exported the data notification function, SMP (S) waited for the data sending request from OBEX (S).

Under situation about having received from the data sending request of OBEX (S), SMP (S) generates normally to receive and is used to represent the whether SMP head of normal independent variable of the data that receive, and this head is attached in the data of data sending request of OBEX (S), thereby being sent data, LMP (S) sends function.Have again, having under the situation of mistake, because the notice of OBEX (S) is stopped, so only to bide one's time be normal waiting.

Then, LMP has been when high level has received data sending request, additional LMP head in the data in this function and form data, and LAP is sent the data sending request function that has added these data.In addition, LMP forms the data of removing the LMP head the data in this function under the situation that has received the data notification function from LAP, and SMP is sent the data notification function that has added these data.

Have again, carrying out not needing to use LMP under the situation of a connection in mode one to one.The LSAP adding that in the LMP head, will add in this case, connectionless value.

LAP adds the LAP head and forms data when having received the data sending request function from LMP in the data in this function, physical layer is sent the UI frame that adds these data of knowing clearly.In addition, LAP forms the data of having removed the LAP head from the data of this UI frame, and LMP is sent the data notification function that has added these data under the situation that has received the Data Receiving notice from physical layer.Have again,, in the LAP head, comprise link address and UI indicating device in present embodiment.

Present embodiment (not having response)

Figure 45 is the precedence diagram of the exchanges data order of expression present embodiment (not having response).And the key diagram of the data structure of the communication data of Figure 44 when being the exchanges data order of expression present embodiment (do not have response).

As shown in figure 45, present embodiment (not having response), transmitter produces the PUT order, and this order is used as the output of UI frame until being sent to low layer.

On the other hand, receiver receives data, gives notice to high level.At this moment, at SMP (S), for the OBEX (S) of high level, notification data is (status=truncated) continuously.

Then, transmitter is when becoming final data, and making expression is the sign connection (ON) and the transmission of final data.To this, if SMP (S) should indicate connection, then receiver is to BOEX (S) notification data complete neat (status=OK), end data exchange sequence.

The transmitter of this moment, the order in the receiver are as described below.

At transmitter, order sends function as data to OBEX (P) to low layer output PUT.But OBEX (P) does not need just can the finish command to the response of all orders.Then, OBEX (P) exports Next Command under the situation that can send with SMP (S).

At receiver, OBEX (S) receives the data notification function from low layer, response is not returned in all orders, and is only received data.

Here, the data transmission function of relevant high level shared in transmitter, receiver and low layer and the head in the data notification function etc. are described.

When SMP receives data transmission function from OBEX, for LMP, (a) size of data hour the size that can send with LPM sends function than data in, these data are divided into the size that LMP can send, when (b) size of data is big the size that can send with LMP sends function than data in, several data are carried out combination, thereby form the following bigger data of size that can send.In addition, SMP generates the SMP head, and this head has added serial number, to the independent variable of the last data of independent variable, the expression of the other side's equipment query data receiving state, expression the SMP of method, apparatus needed whether normal independent variable etc. of the independent variable of the response of OBEX, data that expression receives.Then, LMP is sent data sends function, this function added with this SMP head be attached to carried out above-mentioned cut apart or the data of combination in data.

And, when SMP receives the data notification function from LMP, extract the SMP head the data in this function out, and confirm whether normally whether serial number (that is, do not omitted and arrival sequentially).Then, under normal situation, OBEX is sent the data notification function.At this moment, the data notification function can be by each the data notification function output from low layer, also the data from the data notification function of several low layers can be merged output.

The SMP of transmitter (P) will be the data transmission function to LMP (P) from the data transmission functional transformation of OBEX (P).Then, be that the data of False send under the situation of function received independent variable as final data from OBEX (P), the data that will add the SMP head in these data send to LMP (P).On the contrary, SMP (P) is that the data of True send under the situation of function received independent variable as final data from OBEX (P), will add these data data of sending the final data of function to LMP (P) send function and send, the independent variable that this function makes these data of expression send the response of the OBEX (S) that independent variable that function is a final data or expression need receiver is True.

On the other hand, the SMP of receiver (S) resolves the SMP head according to the data in this data notification function under the situation that has received the data notification function from low layer, and the number of affirmation order.Then, SMP (S) resolves the SMP head, and can confirm under the situation that can normally receive, and LMP (S) is sent data send function.

On the contrary, SMP (S) is detecting under the situation that can not normally receive, and OBEX (S) is notified as mistake.For example, received at 0,1,2,3,5 o'clock, had the 5th should not receive 4 situation for 4.

Thereby, afterwards, SMP (S) waits for that the independent variable of the response of the independent variable of the final data that makes expression SMP head or the OBEX (S) that expression needs receiver is True, reception is that the data notification function of True (has again, even receive also not to OBEX (S) notice) or receive the cut-out notification function or until through certain certain hour, also OBEX (S) is not carried out data notification.

Then, the LMP of transmitter (P) has been when SMP (S) has received the data sending request function, and additional LMP head and form data in the data in this function sends the data sending request function that has added these data to LAP (P).

On the other hand, the LMP of receiver (S) is receiving from LAP (S) under the situation of data notification function, forms the data of having removed the LMP head the data in this function, and SMP (S) is sent the data notification function that has added these data.

Have again, carrying out not needing to use LMP under the situation of a connection in mode one to one.The LSAP adding that in the LMP head, will add in this case, connectionless value.

The LAP of transmitter (P) has been when LMP (P) has received the data sending request function, and additional LAP head and form data in the data in this function sends the UI frame that has added these data to physical layer.

On the other hand, the LAP of receiver (S) forms the data of having removed the LAP head from the data of this UI frame, and LMP (S) is sent the data notification function that has added these data under the situation that has received the Data Receiving notice from physical layer.Have again,, in the LAP head, comprise link address and UI indicating device in present embodiment.

(3-3) cut-out order

IrDA in the past

Figure 46 is a precedence diagram of representing the cut-out order of IrDA in the past.Have again, the data structure of the communication data the during cut-out of IrDA in the past order shown in Figure 36 (b) like that.

(4) respond the switching that has or not

With reference to Figure 50～Figure 57, the data between the communication layers of transmitter and receiver and the stream of parameter are described.

In present embodiment, each communication layers LAP, LMP of transmitter and receiver, SMP, OBEX have the connection request function, are connected notification function, the connection response function, connect and confirm function.These functions are to be used for the function that the LAP layer conducted interviews from high-rise (that is LMP layer).

And as independent variable, above-mentioned function can be specified Data (below, be designated as data) and Requested-Qos or Retumed-Qos.As described above, above-mentioned data are set in each communication layers.

On the other hand, Qos will be by the appointment of the consultation parameter of the baud rate of LAP decision etc. or the high level that the negotiation result notice has comprised OBEX.Have again, even Qos IrDA in the past also is being used.

For example, the application of transmitter or OBEX (P) have added in transmission that needs/when not needing to respond the Qos of such parameter, this Qos is till low layer is sent to LAP (P) successively.Then, LAP (P) reflects the value of this Qos value as consultation parameter (Ack Less Connect), sends to receiver.

Its result, each communication layers of transmitter and receiver is moved according to the appointment of the application of transmitter or the needs of OBEX (P)/do not need to respond, so can carry out two-way/unidirectional connection.

The data between the communication layers when Figure 50～Figure 54 is the order of connection (Figure 39) of expression present embodiment (response is arranged) and the key diagram of the stream of parameter.Have, the parameter of the QoS between OBEX-SMP, between SMP-LAM, between LMP-LAP can be identical again, but also can be different.Therefore, in the drawings, additional-a ,-b ,-c distinguishes.

At transmitter, as shown in figure 50, by con.req (data) (Figure 39), Data that will send to receiver and the data of QoS-1 (QoS of transmitter request) are transferred to low layer from high level.

On the other hand, at receiver, shown in Figure 51, by con.req, only the data with QoS-2 (QoS of receiver request) are transferred to low layer respectively from high level.

Then, at receiver, received moment of SNRM order at LAP (S), the QoS-2 of the QoS-1 of transmitter and this machine relatively forms QoS-3 as the shared and parameter of consulting.Then, shown in Figure 52, LAP (S) notifies with the data from transmitter QoS-3 by con.ind (data) to high level.Each high-rise this QoS-3 of storage, thereby the connection parameter when connecting and keeping.

Then, at receiver, when notice con.resp (data), do not need QoS.Therefore, shown in Figure 53, con.resp (data) only data be transferred to low layer from high level.And, when LAP (S) receives con.resp (data), in the UA response, add QoS-3, and send the UA response.

Then, at transmitter, LAP (P) receives the UA response and QoS-3 is stored as the parameter of consulting.Then, shown in Figure 54, LAP (P) notifies with the data of receiver QoS-3 by con.conf (data) to high level.Each communication layers keeps this QoS-3 as being established the connection parameter in connecting.

In present embodiment, for example,, use Requested-QoS:Baud-Rate+Max-Turn-Around-Time+Disconnect-Threshold+DataSize+Ackless connection+Min-Packet-Interval as the QoS of con.req.And as Con.ind, the QoS of con.conf uses Resultant-QoS:Baud-Rate+Disconnect-Threshold+DataSize+Ac k lessconnection (indication primitive only).

In addition, when the order of connection (Figure 41) of present embodiment (not having response), the data between communication layers and the stream of parameter are following like that.

At transmitter, as shown in figure 50, by con.req (data) (Figure 41), Data that will send receiver and the data of QoS-1 (QoS of transmitter request) are transferred to low layer from high level.

Then, the LAP of transmitter (P) still stores QoS-1 as QoS-3.Then, shown in Figure 54, LAP (P) notifies QoS-3 by con.conf to high level.Each communication layers keeps this QoS-3 as being established the connection parameter in connecting.

On the other hand, at receiver, shown in Figure 51, by con.req, only the data with QoS-2 (QoS of receiver request) are transferred to low layer respectively from high level.

Then, at receiver, in the moment in that LAP (S) has received the SNRM order,, form QoS-3 according to the QoS-1 of transmitter.Have again, under the parameter of QoS-2 does not satisfy situation with the combination of QoS-1, can not receive.

Then, shown in Figure 52, LAP (S) notifies with the data from transmitter QoS-3 by con.ind (data) to high level.Each high-rise this QoS-3 of storage, and the connection parameter when connecting and keeping.

Thus, by using above-mentioned QoS-1 and QoS-2 are carried out high level operation (application), can switch has/does not have response.

Here, as the benchmark of the switching that has/do not have response, the document form of the file of transmission, application, user's selection etc. is considered.

Specifically, under with the situation of document form as benchmark, for example, under the situation of multimedia associated with, there are/do not have response two sides to select, and be telephone directory, mail, schedule files such as (schedule) and will confirming under the received situation of data that there have response automatically to be selected to be just passable.And to use under the situation as benchmark, for example, under the situation of slideshow (slide show), do not have response and automatically selected just can.And under situation about selecting by the user, for example, it is just passable that the user is selected from the menu that has/do not have response shows.

The key diagram of the data between the communication layers when Figure 55～Figure 57 is the order of connection of expression present embodiment and the variation of the stream of parameter.

In transmitter, comprise in the initial SNRM order under the situation of information of all communication layers (Figure 39), can constitute in each communication layers is not to transmit data or parameter while carrying out relaying yet, but as shown in Figure 55, directly be transferred to the LAP layer from each communication layers.

On the contrary, also can constitute as shown in Figure 56, in receiver, also can all take out the data or the parameter that in the SNRM order, comprise, each communication layers as the recipient is directly passed on from the LAP layer.

In addition, also can constitute shown in Figure 57, in transmitter, by data or the parameter of LMP (P) unified OBEX (P), SMP (P), LMP (P), and the parameter of in above-mentioned unified data or parameter, appending LAP (P) by LAP (P), thereby generate the SNRM order.

(5) functional block

Figure 58 is the functional-block diagram of a configuration example of the communication system 1000 of expression present embodiment.

Shown in Figure 58, communication system 1000 comprises: establish the connection of mutual a plurality of communication layers and transmitter 1100 that communicates and receiver 1200.Here, transmitter 1100 and receiver 1200 are connected/cut off request with data with one with required order in being connected of adjacent a plurality of communication layers/cut-out and send reception, thereby tackle with the agreement of establishing being connected/cutting off.

In addition, above-mentioned communication system 1000 receiver 1300 that includes transmitter 1100 and establish the connection of mutual a plurality of communication layers and communicate.Here, transmitter 1100 and receiver 1300 send reception with order required in being connected of a plurality of communication layers/cut-out and data with the request that is connected/cuts off of each communication layers, thereby tackle with the agreement of establishing being connected/cutting off (for example, IrDA in the past).

Have, transmitter 1100, receiver 1200,1300 also can possess respectively as the function of transmitter with as two functions of the function of receiver again.That is, the function by possessing transmitter 1100 and the function of receiver 1200 can constitute the communication equipment that sends reception with the communication protocol of present embodiment.In addition, the function by possessing transmitter 1100 and the function of receiver 1200,1300 can constitute the communication equipment that the communication protocol of the communication protocol of present embodiment and IrDA is in the past switched and sent reception.

Above-mentioned transmitter 1100 comprises at least: request generates parts (connection request generation parts, the request of cut-out generate parts) 1101, request transmit block (connection request transmit block, cut-out request transmit block) 1102, connects set parts (connection set parts) 1103, response receiving-member (response receiving-member) 1104.

Have, above-mentioned request generates parts 1101 and is connected set parts 1103 and is set among each communication layers L2a, L3a, L4a, the L5a again.Above-mentioned request transmit block 1102 and response receiving-member 1104 are set among the communication layers L2a directly over the physical layer L1.

Above-mentioned request generates parts 1101 and has generated the order necessary in the connection that is included in adjacent a plurality of communication layers and the connection request of data.In addition, above-mentioned request generates parts 1101 and has generated the order necessary in the cut-out that is included in adjacent a plurality of communication layers and the cut-out request of data.Have, said here a plurality of communication layers are the intermediate layers (communication layers L2a, L3a, L4a, L56a) except physical layer L1 and application layer L7 again.

Have again, in connection request, will order and the combination of the communication layers of data centralization, cut off and order in the request and the concentrated combination of communication layers of data also can be inconsistent.For example, when connecting, it is two groups that communication layers is concentrated, and establishes connection by two connection requests, and when cutting off, all communication layers is cut off request by one cut off just passable.

In addition, under situation about connecting with the agreement that response is arranged, above-mentioned request generates parts 1101 and make the order that comprises receiver 1200 request transmissions and this connection request corresponding response in connection request.

In addition, under situation about connecting with the agreement that response arranged, above-mentioned request generates parts 1101 and makes to comprise in connection request and send the order that responds when the receiver request msg communicate by letter.

Have again, even under situation about connecting with the agreement that response is arranged, the order of one of them response of the response when above-mentioned request generation parts 1101 also can only comprise with this connection request corresponding response and data communication in connection request.That is, can omit response for connection request, or can omitted data response during communication.Certainly, if omit both responses, then become the connection under the agreement of not having response.

Above-mentioned request is generated the connection request of parts 1101 generations to above-mentioned request transmit block 1102 and the request of cutting off sends to receiver 1200.In addition, above-mentioned response receiving-member 1104 is from receiver 1200 receptions and connection request and cut-out request corresponding response.

Under situation about connecting with the agreement that response arranged, that above-mentioned connection set parts 1103 carries out in each communication layers is corresponding with the connection request that sends from this machine, from the corresponding setting of response of receiver 1200 receptions.

In addition, above-mentioned connection set parts 1103 does not receive and the connection request corresponding response that sends from this machine from receiver, and carry out the setting corresponding with this connection request in each communication layers under situation about connecting with the agreement of not having response.

Above-mentioned receiver 1200 comprises: ask receiving-member (receiving-member is asked in connection request receiving-member, cut-out) 1201, connection establishment parts (connection establishment parts, cut-out parts) 1202, respond generation parts (responding the generation parts) 1203, respond transmit block (response transmit block) 1204.

Have again, above-mentioned request receiving-member 1202 and above-mentioned response transmit block 1204 be set at physical layer L1 directly over communication layers L2a in.Parts 1202 are established in above-mentioned connection and above-mentioned response generation parts 1203 are set among each communication layers L2a, L3a, L4a, the L56a.

Above-mentioned request receiving-member 1201 receives from transmitter 1100 and has comprised the order necessary in the connection of adjacent a plurality of communication layers and the connection request of data.In addition, above-mentioned request receiving-member 1201 receives from transmitter 1100 and has comprised the order necessary in the cut-out of adjacent a plurality of communication layers and the cut-out request of data.
