Description
The present invention is dividing an application of following patent application: application number: 200680003146.5, and the applying date: on January 25th, 2006, denomination of invention: communication equipment, communication system, communication means, signal procedure, telecommunication circuit
Technical field
The present invention relates to be used to carry out recording medium, telecommunication circuit and the mobile phone of communication equipment that the transmission of the transmission of data receives, communication means, signal procedure, embodied on computer readable.
Background technology
In recent years, additional cameras function on mobile phone, thereby the view data of shot by camera is sent to equipment such as television set, printer, and this equipment to carry out the application that image shows predetermined process such as processings universal.
As the interface that connects mobile phone and television set, printer, PC (Personal Computer), the infrared mode (with reference to non-patent literature 1,2) of IrDA (Infrared Data Association) etc. is arranged.
The infrared mode of IrDA etc. owing to have directivity, thereby when having shelter between communication equipment, can not carry out the transmission of data, and the path between communication equipment can carry out data at a high speed and transmit when good.In the IrDA standard, it is that Fast IR (FIR), the communication speed of Very Fast IR (VFIR), the 4Mbps of 16Mbps is the following SIR of 115.2kbps that maximum transfer rate is arranged, and is product till the 4Mbps but the product of selling in the existing market is maximum transfer rate.
Figure 14 is illustrated in the IrDA standard of one of standard as infrared communication, the step till the connection of IrLAP layer is set up.
Main website is the station of at first searching for a side of communication counterpart, that is, be the station that data transfer state is set up in request, is the station of a side of dispatching station search command (XID order).And secondary station is the station of accepting this request, is the station of transmission to a side of the station search response (XID response) of station search command.To be called order to the request (order) at pair station from main website, on the contrary, will be for this order from the pair station replying of main website is called response.
The XID order is to search for whether there is the order that can become secondary station from main website in the distance that can communicate by letter.The SlotNumber of number is illustrated in and sends which order in the expression bracket.
The XID response as the station search response is beamed back at the pair station of having accepted the XID order, makes main website know the processing that our station exists.Main website sends the XID order of the number of regulation, and the SlotNumber of last XID order is made as 255.SlotNumber255 represents that it is last order (XID-END).
Then, but main website uses the SNRM order to make secondary station know that maximum transfer rate, the maximum of our station can receive upward necessary parameter of communication such as data length.The pair station of having accepted this order compares the set point of they and our station, uses the UA response and makes main website know acceptable set point.
If it is discuss in more detail, then following such.That is, in the IrDA standard, can select from 1,6,8,16 from the transmission number of the grouping of the XID of main website order, this value is recorded and narrated in the Discovery flag that XID orders.Then, for example, as shown in Figure 14, with the grouping of XID order is each when sending 8, from the 1st to the 8th till, make SlotNumber respectively from 0 to 7, make SlotNumber 255 send XID-END order at last, and be the pair station of the advisory of last grouping as remote station with it.Then, after sending last grouping, the time through about 500 milliseconds, repeat to send once more grouping from the 1st to the 8th.Have, the transmission between the grouping is spaced apart 25 milliseconds to 85 milliseconds again.
Secondary station is not that reception XID order just determines to beam back the XID response immediately, but after the grouping that receives the SlotNumber with any (value at random), beams back the XID response.For example, when sending the XID command packet of 8 time slots, secondary station can at random determine it is to beam back the XID response after receiving the 1st grouping, still beams back the XID response after receiving the 8th grouping.As an example, in Figure 14, be illustrated in the situation of beaming back the XID response after the 3rd grouping that receives.
Have, this XID order and XID response are carried out with the transfer rate of 9600bps according to SIR by the decision of IrDA standard again.This transfer rate is compared very slow with the 4Mbps of the transfer rate of Frame described later.Therefore, it is long to receive the required time in the transmission that this XID orders and XID responds.Through above step, the station search step between main website and the secondary station finishes.
After the station search step finishes, but main website uses the SNRM order to make secondary station know that maximum transfer rate, the maximum of our station can receive required parameter in the communication of data length etc.The pair station of having accepted this order uses the UA response to make main website know that but the maximum transfer rate of our station, maximum can receive required parameter in the communication of data length etc., but can transmit data length etc. thereby set up, the connection status of the IrLAP between main website and the secondary station by decision maximum transfer rate, maximum.
After connection,, carry out the connection of IrLMP, Tiny TP, OBEX by the packet of IrLAP based on the IrLAP of the command packet of above-mentioned IrLAP.
The connection request of the IrLMP of main website is sent to secondary station by the packet of IrLAP, and the IrLMP at secondary station connects the packet of replying by IrLAP and is sent to main website, carries out the connection of IrLMP.
Then, the connection request of Tiny TP is sent to secondary station by the packet of IrLAP, and the Tiny TP at secondary station connects the packet of replying by IrLAP and is sent to main website, carries out the connection of Tiny TP.
And then, the connection request of the OBEX of main website is sent to secondary station by the packet of IrLAP, the OBEX at secondary station connects the packet of replying by IrLAP and is sent to main website, carries out the connection of OBEX, thereby sets up the connection status that can carry out the transmission of information data.
When disconnecting, the disconnection request of OBEX and reply, the disconnection request of Tiny TP and reply, the disconnection request of IrLMP and the packet of replying by IrLAP transmit, then, transmission is as the DISC order of the disconnection request command grouping of IrLAP and the UA response of dividing into groups as acknowledgement command, and the communications status between main website and the secondary station is disconnected.
In addition, in IrDA, decision is that unit communicates with the frame.The frame of expression IrDA among Figure 16.The frame of IrDA comprises: preamble field, start mark, address field, control field, data field, FCS, end mark.In above-mentioned field, preamble field is used to generate receiving terminal employed receive clock in receiving circuit.In addition, in FCS, comprise the error detection code that is used for error detection occurs.
In frame, S (Supervisory) frame that I (Information) frame that the information that is useful on transmits, the supervision that is used to communicate by letter are controlled and U (Unnumbered) frame of connection that is used to communicate by letter and disconnection.The information that is used for discerning these I, S, U frame is included in above-mentioned control field.
Usually, because the data that are transmitted can not be in the majority with the situation that 1 frame sends, so send after being split into a plurality of I frames or UI frame.The I frame has the data that will transmit in data field, be used for the consecutive number that data are lost check by having, and realizes the high communication of reliability.The UI frame has the data that will transmit in the I field, be not used for the consecutive number that data are lost check but do not have.The S frame is the structure that is not used in the data field of preserving data, be used for transmission receive be ready to complete, busy condition, re-send request may etc.The U frame does not have the such consecutive number of I frame, thus be called as non-number frame, be used for communication pattern setting, reply or the report of abnormality, the foundation or the disconnection of data link.

[non-patent literature 2] Infrared Data Association Serial Infrared Physical LayerSpecification Versionl.4 (May 30,2003)
But in above-mentioned structure in the past, it is long that the generation data transmit the required time, the problem that transmission efficiency descends.
That is, as mentioned above, before the foundation of in IrDA, communicating by letter, need 500 milliseconds read (sensing), based on the station search of XID order, based on the exchange of negotiation (negotiation) parameter of SNRM, UA.
When in communication zone, having a plurality of communication station,, need control the station in the zone in order to prevent the luminous phenomenon that hinders communication because of unexpected station.But, ultrared good directionality, in addition, in fact carrying out under the situation of infrared communication is One-to-one communication mostly, so also need to carry out the station search based on the automatic communication zone of equipment.
And, being defined as 9600bps based on the search of the station of this XID according to the IrDA standard, speed is more much lower than the speed of the 4Mbps of swap data.In addition, before transfer information data, as shown in figure 15, after the connection of having finished IrLAP, IrLMP, Tiny TP, OBEX are carried out the packet exchange of IrLAP successively, each layer sequentially need be connected.Order with OBEX, Tiny TP, IrLMP, IrLAP disconnects similarly when disconnecting.
Because of above reason, transmitting the using method of data with infrared ray to another station information terminal from a certain station information terminal, because the time till time of carrying out this data transmission and disconnection, so transmission efficiency as a whole descends.
In addition, from the using method of portable terminal, when in transmission, having produced mistake, can easily differentiate to send by the user sometimes and fail the image display device transmitted image.For example, sometimes the demonstration of receiving terminal image display device and user send different, show sometimes not to be updated.
The user carries out transmit operation, if until judging that this transmission is that the success or the time of failure are short, even the reliable communication that then is free from mistakes, the user sends once more by operating again sometimes, also can not produce big burden.In such device, the reception that can carry out data is just passable, can save transtation mission circuit and device.
But, also beam back response owing in IrDA, stipulated receiver, so transtation mission circuit and device need be arranged in all receivers to order.

If the response that is received is Success, then transmitter normal termination.
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, the response (returning Continue under the normal condition) of the PUT order beyond OBEX (P) does not need PUT Final (last PUT) order and can send with SMP (P) time, export Next Command.During order beyond PUT Final order or PUT order, wait for data notification function, observe response in these data and the finish command from low layer.
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) accepts the data notification function from low layer, thus the data of acceptance.But OBEX (S) does not return response for the PUT order beyond the PUT Final order, under the situation of the order beyond PUT Final order or the PUT order, sends function and returns response as data.
Here, the data transmission function of high level shared in transmitter, the receiver and low layer and the head in the data notification function etc. are described.
SMP is when accepting data transmission function from OBEX, for LMP, when size that (a) can send with LMP sends data in the function big or small less than data, these data are divided into the size that LMP can send, when size that (b) can send with LMP sends size of data in the function greater than data, several data are carried out combination, the following bigger data of size that formation can send.In addition, SMP forms the SMP head, this head be added into order 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 is needed whether normal independent variable of the independent variable of the response of OBEX, data that expression is received.Then, with added above-mentioned cut apart or the data of combination in the data of data gained after having added this SMP head send function and send to LMP.
Whether normal and then SMP extracts the SMP head out the data in this function when accepting the data notification function from LMP, and confirm serial number (that is, whether arriving in proper order with omission not).Then, under normal situation, send the data notification function to OBEX.At this moment, the data notification function can be exported from the data notification function of low layer by each, also the data from the data notification function of several low layers can be merged back output.
The SMP of transmitter (P) will be the data transmission function to LMP (P) from the data transmission functional transformation of OBEX (P), and the data that send certain data volume of fixing a number of defined send function.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).
SMP (P) is to analyzing from the SMP head in the data notification function of LMP (S), and the data that received in expression as the preparation that can send next data, become the state that can send OBEX (P) when whether normal independent variable is normally received.That is, under this state, can receive data from OBEX (P).
On the contrary, SMP (P) is analyzing the SMP head from the data notification function that is received of LMP (S), thereby in the data that received of expression when normal independent variable is not normally received, from notified data transmission function for can not normally receiving, produce data once more and send function, until making till the independent variable of the other side's equipment query data receiving state is True.SMP (P) repeats to produce once more data and sends function, and the notified receiver of data until whole data transmission functions perhaps repeats the generation once more of certain stipulated number.
And, SMP (P) is that the independent variable of last data is that the data of True are when sending function having accepted from OBEX (P), the independent variable that makes this data of expression send the response of independent variable that function is last data or the OBEX (S) that expression needs receiver is True, has been added into the data to LMP (P) that these data send the final data of function and sends function thereby send.
On the contrary, the SMP of receiver (S) is when LMP (S) has accepted the data notification function, needing the independent variable of response of the OBEX (S) of receiver in last data or expression is under the situation of True, send the data notification function to OBEX (S), this data notification function has added the data except the head of SMP (S).
In addition, SMP (S) is when LMP (S) has accepted the data notification function, and the data in this data notification function are analyzed the SMP head, and confirms serial number.If SMP (S) can normally receive before the head that independent variable to receiver data query accepting state is True accepting, then expression can normally receive and be used to represent whether normal independent variable of the data that received, thereby form the SMP head, and it is sent data transmission function as data to LMP (S).
On the other hand, detect can not normally receive the time at SMP (S), storage is predicted to be the number of the SMP head that can not normally receive.For example, receiving 0,1,2,3,5 o'clock, the 5th should not receive under 4 the situation for 4, and being predicted to be the number that can not normally receive is 4.Then, after it, whether the independent variable to receiver data query accepting state that SMP (S) only investigates the SMP head is True, stops the output to the data notification function of OBEX (S).
SMP (S) is receiving under the situation of data notification function that independent variable to receiver data query accepting state is True, with the data independent variable of representing to be received whether normal independent variable can not normally receive as expression, the number of the SMP head that formation can not normally receive is inserted into the SMP head in the field of addition sequence number, sends function thereby it is sent data as data to LMP (S).
In addition, SMP (S) is under the situation of data notification function of True at the independent variable of the response of having accepted independent variable that expression is last data or the OBEX (S) that expression needs receiver, after having exported the data notification function, wait for data sending request from OBEX (S) to OBEX (S).
SMP (S) is when the data sending request of having accepted from OBEX (S), the data SMP head whether normal independent variable can not normally receive that formation is received expression, it is attached in the data of data sending request of OBEX (S), sends function thereby LMP (S) is sent data.Have again, having under the situation of mistake,, be counted as being in just often so wait to bide one's time owing to the notice that stops OBEX (S).
Then, LMP when having accepted the data sending request function from high level, 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 having removed the LMP head the data in this function when having accepted 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.In this case, in the LMP head, add the LSAP that connectionless value is arranged.
LAP when having accepted the data sending request function from LMP, additional LAP head on the data in this function and form data, and physical layer is sent the UI frame that has added these data.In addition, LAP forms the data of having removed the LAP head from the data of this UI frame when having accepted the Data Receiving notice from physical layer, and LMP is sent the data notification function that has added these data.Have again,, in the LAP head, include link address and UI designator in present embodiment.
[B] do not have 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 transferred into low layer, is output as the UI frame.
On the other hand, receiver is accepted data, and high level is given notice.At this moment, at SMP (S), to the OBEX (S) of high level, notification data is (status=truncated) continuously.
When becoming last data, transmitter is that the mark of last data is opened and sent with expression.To this, if being labeled as, this opens, then the SMP of receiver (S) gathers (status=OK) to OBEX (S) notification data, thus the 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 be sent by SMP (P).
At receiver, OBEX (S) accepts the data notification function from low layer, and all orders are not returned response and only accepted data.
Here, the data transmission function of high level shared in transmitter, the receiver and low layer and the head in the data notification function etc. are described.
SMP is when accepting data transmission function from OBEX, for LMP, when size that (a) can send with LMP sends data in the function big or small less than data, these data are divided into the size that LMP can send, when size that (b) can send with LMP sends size of data in the function greater than data, several data are carried out combination, the following bigger data of size that formation can send.In addition, SMP forms the SMP head, this head be added into order 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 is needed whether normal independent variable of the independent variable of the response of OBEX, data that expression is received.Then, with added above-mentioned cut apart or the data of combination in the data of data gained after having added this SMP head send function and send to LMP.
Whether normal and then SMP extracts the SMP head out the data in this function when accepting the data notification function from LMP, and confirm serial number (that is, whether arriving in proper order with omission not).Then, under normal situation, send the data notification function to OBEX.At this moment, the data notification function can be exported from the data notification function of low layer by each, also the data from the data notification function of several low layers can be merged back 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 accepted 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 Ture send under the situation of function accepted independent variable as final data from OBEX (P), the independent variable that makes this data of expression send the response of independent variable that function is last data or the OBEX (S) that expression needs receiver is True, thereby the data that send LMP (P) send function, and these data send the final data that function has added this data transmission function.
On the other hand, the SMP of receiver (S) is when having accepted the data notification function from low layer, and the data in this data notification function are analyzed the SMP head, the number of affirmation order.Then, SMP (S) analyzes the SMP head, thereby can confirm under the situation that can normally receive, and LMP (S) is sent data send function.
On the contrary, SMP (S) is detecting can not normally receive the time, and OBEX (S) notice has been produced mistake.For example, receiving 0,1,2,3,5 o'clock, being the 5th should not receive 4 situation for 4.
Then, SMP (S) waits for that the independent variable of the response of the independent variable of the last data of representing the SMP head or the OBEX (S) that expression needs receiver is True, OBEX (S) is not carried out data notification, till accepting data notification function (having again) or accepting to disconnect notification function or certain certain hour of process even accept also not notify OBEX (S) as True.
Then, the LMP of transmitter (P) has been when SMP (S) has accepted the data sending request function, additional LMP head in the data in this function and form data, and send the data sending request function that has added these data to LAP (P).
On the other hand, the LMP of receiver (S) is accepting 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 sends the data notification function that has added these data to SMP (S).
Have again, carrying out not needing to use LMP under the situation of a connection in mode one to one.In this case, in the LMP head, add the LSAP that connectionless value is arranged.
The LAP of transmitter (P) has been when LMP (P) has accepted the data sending request function, additional LAP head in the data in this function and form data, and send 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 UI frame, and LMP (S) is sent the data notification function that has added these data under the situation of having accepted the Data Receiving notice from physical layer.Have again,, in the LAP head, comprise link address and UI designator in present embodiment.

(4) have or not the switching of response
With reference to Figure 49～Figure 56, flowing of data between the communication layers of transmitter and receiver and parameter is described.
In present embodiment, each communication layers LAP, LMP of transmitter and receiver, SMP, OBEX have the connection request function, are connected notification function, connect and reply function, connection affirmation function.These functions are to be used for the function that the LAP layer conducted interviews from high-rise (that is LMP layer).
And above-mentioned function can specify Data (below, be designated as data) and Requested-Qos or Returned-Qos as independent variable.As described above, above-mentioned data are set in each communication layers.
On the other hand, the appointment and the negotiation result notice of the consultation parameter of the baud rate that Qos will be determined by LAP etc. are high-rise, and high level has comprised OBEX.Have again, even Qos IrDA in the past also is used.
For example, when the application of transmitter or OBEX (P) sent the Qos added the parameter that needs/do not need respond, its quilt in turn transmitted until LAP (P) to low layer.Then, LAP (P) is reflected the value of this Qos value as consultation parameter (Ack Less Connect), is sent 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, and can carry out twocouese/unidirectional connection.
The data between the communication layers when Figure 49～Figure 53 is the order of connection (Figure 40) of expression present embodiment (response is arranged) and the key diagram that flows of parameter.Have, the parameter of the QoS between OBEX-SMP, between SMP-LMP, between LMP-LAP can be identical again, also can be different.Therefore, in the drawings, additional-a ,-b ,-c distinguishes.
At transmitter, as shown in figure 49, by con.req (data) (Figure 40), Data that will send 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, as shown in figure 50, 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, accepted 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 parameter of common connection.Then, shown in Figure 51, LAP (S) notifies high level with QoS-3 with the data from transmitter by con.ind (data).Each high-rise this QoS-3 of storage, the connection parameter during as connection is preserved.
Then, at receiver, when notice con.resp (data), do not need QoS.Therefore, shown in Figure 52, only data are transferred to low layer from high level in con.resp (data).Then, when LAP (S) accepts con.resp (data), in the UA response, add QoS-3, send the UA response then.
Then, at transmitter, LAP (P) accepts the UA response and QoS-3 is stored as the parameter that connects.Then, shown in Figure 53, LAP (P) notifies high level with QoS-3 with the data of receiver by con.conf (data).Each communication layers is preserved this QoS-3 as being established the connection parameter that connects.
In present embodiment, for example,, use Requested-QoS:Baud-Rate+Max-Turn-Around-Time+Disconnect+ DataSize+Ack lessconnection+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 less connection (indication primitive only).
In addition, when the order of connection (Figure 42) of present embodiment (do not have response), data between communication layers and parameter mobile following such.
At transmitter, as shown in figure 49, by con.req (data) (Figure 42), 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) directly stores QoS-1 as QoS-3.Then, shown in Figure 53, LAP (P) is high-rise with the QoS-3 notice by con.conf.Each communication layers is preserved this QoS-3 as the connection parameter of the connection of having established.
On the other hand, at receiver, as shown in figure 50, 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,,, set QoS-3 according to the QoS-1 of transmitter in the moment that LAP (S) has accepted the SNRM order.Have again, under the situation of the combination of parameter that does not satisfy QoS-2 and QoS-1, can not receive.
Then, shown in Figure 51, LAP (S) notifies high level with QoS-3 with the data from transmitter by con.ind (data).Each high-rise this QoS-3 of storage, the connection parameter during as connection is preserved.
Thus, by using above-mentioned QoS-1 and QoS-2 are carried out high level (application) operation, can switch has/does not have response.
Here, as the switching benchmark that has/do not have response, the file format of the file that consideration is sent, application, user's selection etc.
Specifically, when being benchmark, for example, response two sides under the situation of multimedia associated with, should have been selected/not have with the file format, being the file of phone directory, mail, timetable etc. and will confirming under the received situation of data, also can automatically select response.In addition, when being applied as benchmark, under the situation that lantern slide shows, can automatically select does not have response yet.In addition, under situation, for example, the user from showing, the menu that has/do not have response is selected based on user's selection.
The key diagram of the data between the communication layers when Figure 54～Figure 56 is the order of connection of expression present embodiment and the variation that flows of parameter.
In transmitter, in initial SNRM order, contain under the situation of information of all communication layers (Figure 40), also can constitute and not be that one side relaying in each communication layers transmits (Figure 49) on one side with data and parameter, but shown in Figure 54, data and parameter directly are transferred to the LAP layer from each communication layers.
On the contrary, shown in Figure 55, in receiver, also can constitute the data and the parameter that are comprised in the SNRM order are all taken out, directly be transferred to as each communication layers that mails to the destination from the LAP layer.
In addition, shown in Figure 56, in transmitter, in the data and parameter set of LMP (P) with OBEX (P), SMP (P), LMP (P), and then by LAP (P) after above-mentioned concentrate data and parameter in append LAP (P) parameter, thereby generate the SNRM order.
