[summary]

(communication layers)

In each execution mode described later, describe the structure and the action of the transmitter and the receiver of communication system of the present invention in detail based on the OSI7 layer model.Here, the OSI7 layer model is the model that is known as what is called " OSI basic reference model " " osi layer model ".

In the OSI7 layer model, for the data communication that realizes that different machines are middle, the communication function that computer should have is split into 7 layers, has defined the functional module of standard in each layer.

Specifically, the 1st layer (physical layer) served as and is used for data are sent to electrical conversion and machine work on the telecommunication circuit.The 2nd layer (data link layer) guaranteed the communication path of physics and communicated error detection occurs of the data that flow through in the path etc.The 3rd layer (network layer) communicates the selection in path and the management of the address in the communication path.The 4th layer (transport layer) carried out data compression and error correction, sent control etc. again.The 5th layer (session layer) communicates the establishment and the opening in the virtual path (connection) that the transmission that is used to carry out data between the program receives.The 6th layer (presentation layer) will be the easy form of understanding of user from the 5th layer of data conversion that obtains, and will be the form that is suitable for communicating by letter from the 7th layer of data conversion of passing on maybe.The 7th layer (application layer) will utilize the various services of data communication to offer people and other program.

Each communication layers of the communication system of each execution mode also has the corresponding equal function of layer with above-mentioned OSI7 layer model.But in each execution mode, above-mentioned communication system adopts 6 layers structure with session layer and presentation layer unification.In addition, omit explanation for application layer.

The present invention can be widely used in transmitter and establish in the communication system that is connected and communicates of a plurality of communication layers with receiver.That is, cutting apart of communication function also can be not according to the OSI7 layer model.In addition, if the communication layers that connects is a plurality of, then the number of communication layers can be selected arbitrarily.

In addition, the present invention connects the required time by concentrating the connection request of a plurality of communication layers thereby shorten, even therefore also connect easily under the situation that communication path cuts off again.Thereby, the present invention be particularly suitable for that communication path cuts off easily for example based in the ultrared radio communication.But, the present invention other radio communication and wire communication in also effective.

In each execution mode,, describe based on the IrSimple of an application examples of the present invention for the convenience that illustrates.But the present invention is not limited to IrSimple.In addition, IrSimple is the product that the part of functions of in the past IrDA has been carried out improvement.

In each execution mode, according to IrSimple data link layer, network layer, transport layer, session layer+presentation layer are expressed as LAP, LMP, SMP, OBEX respectively sometimes.

(IrLMP layer (LSAP))

The present invention relates generally to network layer.Below, the network layer that IrDA and IrSimple are described is the IrLMP layer.

IrLMP (Infrared Link Management Protocol) layer is in order to use the IrLAP layer as low layer to transmit the data of a plurality of higher layer applications expeditiously and carry out multiplexed.Specifically, in 1 pair 1 was communicated by letter, under the situation of the application of having started a plurality of high levels or in the communication of 1 couple of N, the LMP layer generated each and uses desired logic channel, and the high-rise transmission of using this channel to carry out data receives.This logic channel is LSAP (Link Service Access Point).

For example, in 1 pair 1 is communicated by letter, under the situation of the application of starting a plurality of high levels, when connecting, the high level of transmitter (main website) carries out the logic channel request (for example 1) of this equipment to the LMP layer, becomes the inquiry of logic channel of application 1 (app1) of the connecting object of the other side's equipment simultaneously.Receive information main website the LMP layer at first the Station Control of the connection control by being responsible for the LAP layer finished after the connection of LAP layer, the transmission source logic channel (SLSAP:Source Link ServiceAccess Point) of this equipment is set at described 1, and data transmission requests order (data are the bind command of LMP layer) is transferred to the LAP layer.At this moment, the transmission source logic channel (1) that keeps transmission.

Then, when the LMP layer of receiver (secondary) is received described data transmission requests order (data are the bind command of LMP layer) from low layer, resolve the transmission source logic channel of the main website in the bind command, and receive together notice high level with bind command.The high level of receiving the secondary of information is set at logic channel to method, apparatus with the logic channel of logic channel (SLSAP) of the application 1 of this equipment (for example 2) and main website, and order transfers to the LMP layer as connection response.The LMP layer of receiving the secondary of message is set the logic channel (DLSAP:Destination Link Service Access Point=1) from the application of the logic channel (SLSAP=2) of the application 1 of this equipment of high level and main website, transfers to low layer as data transmission requests order (data are the connection response order of LMP layer).

Then, after the LMP layer of main website is received message by low layer, because the transmission destination logic channel (DLSAP=1) in the connection response order is consistent with the transmission source logic channel (1) of described maintenance, therefore to the application 1 notice connection response order reception notification of high level, notify the logic channel (2) of secondary simultaneously.

When data transmit, use 1 and use the logic channel that when connecting, generates to carry out the data transmission.Specifically, main website sets transmission source logic channel (SLSAP=1) respectively and sends destination logic channel (DLSAP=2) when data transmit, thereby carry out the transmission of data, secondary sets transmission source logic channel (SLSAP=2) and sends destination logic channel (DLSAP=1), thereby carries out the transmission of data.

In addition, when using the connection of 2 (app2), carry out above-mentioned connection processing too.

(problem of IrLMP layer)

In the infrared communication between the equipment that current IrDA has been installed, nearly all be 1 pair 1 communication, and, also nearly all be that file transmits (being applied as of starting) as using.

As mentioned above, in existing IrLMP standard, data during for the communication of the equipment of realizing 1 couple of N and a plurality of application starting transmit, exist the generation of logic channel to handle, but as previously mentioned, in most communication, because only start an application, therefore only formed logic channel, the exchange that is used for this frame becomes waste in form.That is, the communication in 1 pair 1 equipment and being applied as under one the situation can be omitted the processing among the Station end point.

Therefore, thus consider to be predetermined described logic channel and simplify network layer.But if constitute like this, then under the situation in the connection bag that only the connection data of high level will be included in the LAP layer, the substandard connection processing of existing IrLMP can not be handled.Network layer of the present invention is with the communication of 1 pair 1 equipment and to be applied as one situation be prerequisite, in the interchangeability that keeps with the IrLMP standard, simplifies the sequential that connects, cuts off.

[execution mode 1]

Illustrate that based on Fig. 1,2 an embodiment of the invention are as follows.

Fig. 1 represents the signal timing diagram of present embodiment, and Fig. 5 represents block diagram, but the present invention is not limited to this.In addition, as high-rise, adopt OBEX and TinyTP, but be not limited to this among Fig. 5.In addition, recorded and narrated the network layer protocol control unit as independent layer among Fig. 5, but equal function is arrived high level and low layer by unification, network layer protocol control unit not individualism also can.In addition, as long as each module among Fig. 5 can realize its function, can be software or hardware.

As shown in Figure 1, at first the high-rise control unit 511 of main website sends the connection request order 1 (LM_con_req1) that contains the required data of connection.After receiving this connection request order 1,512 pairs of IrLAP layers of network layer protocol control unit control unit 513 of main website sends the connection request order 2 (LAP_con_req2) that has added the data that contain in connection request order 1.The IrLAP layer control unit 513 of main website receives connection request order 2, and sends the SNRM order that has added the data that contain in connection request order 2 via 514 pairs of secondarys of transmitting element.

In secondary, receiving element 515 receives this SNRM order, and 513 pairs of network layer protocol control units 512 of IrLAP layer control unit send the connection request order reception notification 1 (LAP_con_ind1) that has comprised the data that contain in the SNRM order.512 pairs of high-rise control units 511 of the network layer protocol control unit of secondary send the connection request reception notification 2 (LM_con_ind2) that has comprised the data that contain in connection request order reception notification 1.The high-rise control unit 511 of secondary of receiving this connection request reception notification 2 is in order to establish and being connected of main website, to the network layer protocol control unit 512 of secondary send contain with being connected of main website required data connection confirm order 1 (LM_con_resp1).

The IrLAP layer control unit 513 of 512 pairs of secondarys of network layer protocol control unit of secondary sends to connect confirms to order the connection that contains in 1 to confirm order 2 (LAP_con_rsp2).The IrLAP layer control unit 513 of secondary sends to have comprised via 514 pairs of main websites of transmitting element and connects the UA response of confirming to order the data that contain in 2.

The network layer protocol control unit 512 of 513 pairs of main websites of IrLAP layer control unit that is received the main website of this UA response by receiving element 515 sends the connection that has comprised the data that contain in the UA response and confirms order reception notification 1 (LAP_con_conf1).The network layer protocol control unit 512 of main website receives to connect to be confirmed order reception notifications 1 and the high-rise control unit 511 of main website is sent to have comprised connecting the connection of confirming the data that contain in the order reception notification 1 to confirm order reception notification (LM_con_conf2).

(3-2) data interchange time sequence

[A] has response

Figure 22 is the sequential chart of the data interchange time sequence of present embodiment (response is arranged).The key diagram of data structure of the communication data when in addition, Figure 23 is the data interchange time sequence of expression present embodiment (response is arranged).

As shown in figure 22, in present embodiment (response is arranged), the PUT order takes place in transmitter, and it is communicated to low layer and exports as UI frame (Figure 16 (b)).

On the other hand, receiver is obtained data and high level is submitted to notice.At this moment, in SMP (S), to OBEX (S) the notice continuation data (status=truncated) of high level.

Transmitter will be used to confirm that the mark unlatching back whether data normally arrive sends after the bag that has sent a certain fixed number.After receiving information, in receiver, SMP (S) has zero defect to transmitter notice, and the situation that mistake is arranged send a notice take place mistake number.

If zero defect then transmitter output package then is if having mistake then transmitter sends the later bag of bag that has mistake again.

When arriving data last, transmitter is that the last mark of data is opened the back and sent with expression.And in receiver, if this mark opens SMP (S) to OBEX (S) notification data complete (status=OK), and wait for the response of OBEX (S).Then, when the response of OBEX (S) has taken place, these data are communicated to low layer, and export as the UI frame.

If the response that receives is " Success " then transmitter normal termination.

Transmitter, the sequential in the receiver of this moment are as follows.

In transmitter, OBEX (P) sends function with the PUT order as data low layer is exported.Wherein, under the situation that OBEX (P) can be sent by SMP (P) in the response that does not need PUT Final (last PUT) order PUT order in addition (returning " Continue " under the normal situation), the order that output is followed.Under the situation of the order beyond PUT Final order or the PUT order, wait for data notification function from low layer, see response in these data and the finish command.

Here, data transmission function is the function (Data Request) that the low layer request msg is sent.In addition, the data notification function is to be used to notify the function (Data Indicate) that receives data from low layer.

In 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 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 identical in transmitter, the receiver and low layer and the head in the data notification function etc. are described.

If SMP receives that from OBEX data send function, then for LMP, (a) when size that LMP can send sends data in the function big or small less than data, these data are divided into the size that LMP can send, (b) when size that LMP can send sends data in the function big or small greater than data, with several data combinations, thereby generate the following bigger data of size that can send.In addition, SMP generates the SMP head, this SMP head added order number, the last independent variable, expression that are used for independent variable, expression data to the other side's equipment query data receiving state be whether normal independent variable etc. of the necessary independent variable of response of OBEX, data that expression receives to the SMP of method, apparatus.Then, LMP is sent data sends function, these data send function added with this SMP head append to above-mentioned cut apart or the data of combination in after data.

And SMP removes the SMP head the data in this function after receiving the data notification function from LMP, confirms whether normally whether serial number (that is, come according to the order of removing).And, 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 can be several merges the back from the data of the data notification function of low layer and export.

It is that data to LMP (P) send function that the SMP of transmitter (P) will send functional transformation from the data of OBEX (P), and send the data transmission function of data volume of a certain fixed number of regulation.Then, SMP (P) will be used for independent variable to receiver data query accepting state and be made as and send data behind the True and send function, wait 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 represented normally to receive that expression receives, think and finished the preparation that sends data then, become the state that can send OBEX (P).That is, under this state, can accept data from OBEX (P).

On the contrary, SMP (P) resolves the SMP head of the data notification function obtained from LMP (S), under the data situation whether normal independent variable is represented normally not receive that expression receives, take place once more to fail the normal data transmission function that receives to the data transmission function that will be used for the independent variable of the other side's equipment query data receiving state is made as True from notified.SMP (P) repeated to take place before the data that receiver notice total data sent function again, perhaps repeated the generation again of stipulated number.

And then, SMP (P) is that the data of True send under the situation of function from OBEX (P) receiving the last independent variable that is considered to data, the data to LMP (P) for the last data that added this data transmission function send function, will this data of expression sending function is the last independent variable of data, and perhaps expression is sent after needing the independent variable of response of the OBEX (S) of receiver to be made as True.

On the contrary, the SMP of receiver (S) is when LMP (S) receives the data notification function, independent variable in the response of the OBEX (S) that needs receiver for the last of data or expression is under the situation of True, OBEX (S) is sent the data notification function, and this data notification function has added the data after the head of SMP (S) removed.

In addition, SMP (S) is obtaining under the situation of data notification function from LMP (S), by the data parsing SMP head in this data notification function, and affirmation order number.SMP (S) is if receiving that the independent variable that is used for receiver data query accepting state can normally receive before being the head of True, then whether normal independent variable is made as the independent variable that normally receives and generates the SMP head data that expression is received, and it is sent data transmission function as data to LMP (S).

On the other hand, SMP (S) is detecting not under the situation about normally receiving, storage be predicted to be the SMP head of failing normally to receive number.For example, receiving 0,1,2,3,5 o'clock, should but not receive under 4 the situation for 4 for the 5th, be predicted to be and fail that normal what receive number is 4.And after this, SMP (S) only investigates whether the independent variable that is used for 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 the independent variable that is used for receiver data query accepting state is True, the data that expression is received whether normal independent variable are made as and fail the normal independent variable that receives, generation will be failed the SMP head after the field that has added serial number of number being inserted into of the normal SMP head that receives, and it is sent data as data to LMP (S) send function.

In addition, SMP (S) is that the independent variable of response of the last independent variable of data or the OBEX (S) that expression needs receiver is under the situation of data notification function of True receiving expression, after OBEX (S) has been exported the data notification function, wait for data sending request from OBEX (S).

SMP (S) is under situation about receiving from the data sending request of OBEX (S), whether normal independent variable is made as the SMP head that normally receives to the data that generation receives expression, and after appending to them in the data of data sending request of OBEX (S), LMP (S) is sent data send function.In addition, having under the situation of mistake, because the notice of OBEX (S) is stopped, waiting therefore that to bide one's time only be just often.

Then,, the data in this function are added the LMP head and generated data, and LAP is sent the data sending request function that has added these data when high level is received the data sending request function at LMP.In addition, LMP receiving from LAP under the situation of data notification function, generates the data of having removed the data in this function after the LMP head, and SMP is sent the data notification function that has added these data.

In addition, under 1 pair 1 situation of carrying out a connection, needn't use LMP.In this case, the LSAP that has added connectionless value enters the LMP head.

LAP adds the LAP head and generates data the data in this function, and physical layer is sent the UI frame that has added these data when receiving the data sending request function from LMP.In addition, LAP is under the situation of receiving the Data Receiving notice from physical layer, and the data after the LAP head are removed in generation from the data of this UI frame, and LMP is sent the data notification function that has added these data.In addition, in the present embodiment, contain link address and UI sign (indicator) in the LAP head.

[B] do not have response

Figure 24 is the sequential chart of the data interchange time sequence of present embodiment (not having response).The key diagram of the data structure of the communication data when in addition, Figure 23 is the data interchange time sequence of expression present embodiment (do not have response).

As shown in figure 24, in present embodiment (not having response), the PUT order takes place in transmitter, and it is communicated to low layer and exports as the UI frame.

Then, when transmitter becomes data last, will be used to represent to be that the last mark of data is opened the back and sent.And in receiver, if this is labeled as unlatching, then SMP (S) is to OBEX (S) notification data complete (status=OK), and end data exchange sequential.

Transmitter, the sequential in the receiver of this moment are as follows.

In transmitter, OBEX (P) sends function with the PUT order as data low layer is exported.Wherein, OBEX (P) need be for the response of all orders and can the finish command.Then, under the situation that SMP (P) can send, OBEX (P) output order then.

In receiver, OBEX (S) receives the data notification function from low layer, and all orders are not returned response and only obtained data.

The SMP of transmitter (P) will be the data transmission function to LMP (P) from the data transmission functional transformation of OBEX (P).Then, receiving that from OBEX (P) the last independent variable that is considered to data is that the data of False send under the situation of function, sends the data of these data having been added the SMP head to LMP (P).And SMP (P) is receiving that from OBEX (P) the last independent variable that is considered to data is that the data of True send under the situation of function, the data to LMP (P) for the last data that added this data transmission function send function, will this data of expression sending function is the last independent variable of data, and perhaps expression is sent after needing the independent variable of response of the OBEX (S) of receiver to be made as True.

On the other hand, the SMP of receiver (S) is obtaining from low layer under the situation of data notification function, by the data parsing SMP head in this data notification function, and affirmation order number.Then, SMP (S) resolves the SMP head, under the situation of having confirmed normal reception, LMP (S) is sent data send function.

On the contrary, SMP (S) notifies OBEX (S) as mistake detecting under the situation about normally not receiving.For example, receiving 0,1,2,3,5 o'clock, should but not receive 4 situation for 4 for the 5th.

Then, SMP (S) waits for that the independent variable of the response of the last independent variable of the data of representing the SMP head or the OBEX (S) that expression needs receiver is True, up to the data notification function of receiving True (in addition, even receive also not to OBEX (S) notice) or receive and cut off notification function or through till certain certain hour, OBEX (S) is not carried out data notification.

Then,, the data in this function are added the LMP head and generated data, and LAP (P) is sent the data sending request function that has added these data when SMP (S) receives the data sending request function at the LMP of transmitter (P).

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

The LAP of transmitter (P) adds the LAP head and generates data the data in this function, and physical layer is sent the UI frame that has added these data when LMP (P) receives the data sending request function.

On the other hand, the LAP of receiver (S) is under the situation of receiving the Data Receiving notice from physical layer, and the data after the LAP head are removed in generation from the data of this UI frame, and LMP (S) is sent the data notification function that has added these data.In addition, in the present embodiment, contain link address and UI sign in the LAP head.

(4) have or not the switching of response

Flowing of data between the communication layers of transmitter and receiver and parameter is described with reference to Figure 28～Figure 35.

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

And above-mentioned function can be specified Data (following note is done data) and Requested-QoS or Returned-QoS as independent variable.As mentioned above, above-mentioned data are set in each communication.

On the other hand, QoS will be notified to the high level that comprises OBEX by the appointment or the negotiation result of the consultation parameters such as baud rate of LAP decision.In addition, QoS also uses in IrDA in the past.

For example, after the application of transmitter or OBEX (P) sent the QoS that has added the parameter that needs/do not need respond, it was communicated to LAP (P) to low layer successively.Then, LAP (P) is reflected as the value of consultation parameter (Ack Less Connect) with the value of this QoS, sends to receiver.

Its result because each communication layers of transmitter and receiver needs the appointment of the response of the application of transmitter or OBEX (P) to move as required/not, therefore can carry out two-way/unidirectional connection.

The data between communication layers when Figure 28～Figure 32 is the connection sequential (Figure 19) of explanation present embodiment (response is arranged) and the key diagram that flows of parameter.In addition, the parameter of the QoS between the OBEX-SMP, between the SMP-LMP, between the LMP-LAP can be the same or different.Therefore, in the drawings, additional-a ,-b ,-c distinguished.

In transmitter, as shown in figure 28, Data that (Figure 19) will send receiver by con.req (data) and the data of QoS-1 (QoS that transmitter requires) are transferred to low layer from high level.

On the other hand, in receiver, as shown in figure 29, only the data of QoS-2 (QoS that receiver requires) are transferred to low layer respectively from high level by con.req.

Then, in receiver, receive the moment that SNRM orders, the QoS-1 of transmitter and the QoS-2 of this machine are compared, generate QoS-3 as common negotiation parameter at LAP (S).Then, as shown in figure 30, LAP (S) by con.ind (data) with QoS-3 with together be notified to high level from the data of transmitter.Each high-rise this QoS-3 of storage, and the connection parameter when connecting keeps.

Then, in receiver, when notice con.resp (data), do not need QoS.Thereby as shown in figure 31, by con.resp (data), only data are transferred to low layer from high level.Then, if LAP (S) receives con.resp (data), then in the UA response, send the UA response behind the adding QoS-3.

Then, in transmitter, LAP (P) receives the UA response and QoS-3 is stored as negotiation parameter.Then, shown in figure 32, LAP (A) together is notified to high level by con.conf (data) with the data of QoS-3 and receiver.Each communication layers keeps this QoS-3 as the connection parameter in the connection of establishing.

In the present embodiment, for example,, use Requested-QoS:Baud-Rate+Max-Turn-Around-Time+Disconnect-Threshold+DataSize+Ack less connection+Min-Packet-Interval as the QoS of con.req.In addition, 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 connection sequential (Figure 21) of present embodiment (do not have response), data between the communication layers and parameter mobile as follows.

In transmitter, as shown in figure 28, Data that (Figure 21) will send receiver by con.req (data) and the data of QoS-1 (QoS that transmitter requires) are transferred to low layer from high level.

Then, the LAP of transmitter (P) stores the QoS-1 former state as QoS-3.Then, shown in figure 32, LAP (P) is notified to high level by con.conf with QoS-3.Each communication layers keeps this QoS-3 as the connection parameter in the connection of establishing.

Then, in receiver, receive moment of SNRM order at LAP (S), with the QoS-1 of transmitter as QoS-3.In addition, the parameter of QoS-2 by with the ungratified situation of the combination of QoS-1 under can not receive.

Then, as shown in figure 30, LAP (S) by con.ind (data) with QoS-3 with together be notified to high level from the data of transmitter.Each high-rise this QoS-3 of storage, and the connection parameter when connecting keeps.

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

Here, there is/do not have the benchmark that responds, the document form of the file that consideration sends, application, user's selection etc. as switching.

Specifically, under with the situation of document form, for example as benchmark, also can be under the situation of multimedia associated with, selection has/does not have and responds both, being file such as telephone directory, mail, schedule and wishing to confirm under the received situation of data, automatically selects to have response.In addition, under with the situation that is applied as benchmark, for example, also can under the situation of magic lantern, automatically select not have response.In addition, under situation about selecting, for example, the user from showing, the menu that has/do not have response is selected based on the user.

The key diagram of the data between the communication layers when Figure 33～Figure 35 is the connection sequential of expression present embodiment and the variation of the flow process of parameter.

In transmitter, in initial SNRM order, contain under the situation of information of all communication layers (Figure 19), also can not to pass on (Figure 28), but as shown in figure 33, directly be transferred to the LAP layer from each communication layers by each communication layers relay data or parameter.

Otherwise, as shown in figure 34, in receiver, also the data or the parameter that contain in the SNRM order all can be taken out, directly be transferred to each communication layers as destination address from the LAP layer.

In addition, as Figure 35, in transmitter, also can data or the parameter of OBEX (P), SMP (P), LMP (P) is unified by LMP (P), and then, by LAP (P) above-mentioned after reunification data or parameter in append the parameter of LAP (P) and generate SNRM order.
