Slave which communicates one master, its master, and directly About one network constituted, it is Piconet. A is called. Two or more A net which has a master Network group (namely, Network group composition carried out by a plurality of Piconet) CAS evening 1 Net is called.

Next, bull 1 Li when communicating between apparatus by Thu 1 A Kind of An A class is explained. Bull 1 At Tooth, it is [ There is An, ] S C O (Synchronou S Connection-Oriented). Link And AC L 2 kinds of communication Li of a link (Asynchronous Con nection-Less) Applique 1 Chiyo Proper use has become possible by the use of A.

S It is communication at 1 to 1 between CO link, a master, and a specific slave. It is a connection type to perform and he is what is called line switching type Li. It is An. This Li An and Ablis of which real-time nature, such as a sound, is mainly required Ke 1 Chiyo It is used for A. This S C 0 link and Piconet Inside of A Communication Li In An, it is communication Throttling beforehand at a constant interval. Even if A is secured and there is transmission of other data in the middle of , it is data Through of S C 0 link. Priority is given to Trust. namely, a figure -- as [ show / in 13 ] -- a master and A between Loew -- S C 0 communication Slot -- a constant interval -- mutual -- transmission -- To be.

It is Support about three S CO links at the maximum simultaneously to this S C O link and one master. A can be carried out. one [ in this case, ] as opposed to three different slaves from the case where three S C O links are supported with a slave -- it -- the S C 0 link of one . Re -- Support There is a To case. The S C 0 link does not have a retransmission-of-message function, and are and S C 0. Bucket transmitted in a ring An error correcting code is added to ♪. It is not carried out.

A A C L link and what is called a bucket It is a A exchange type connection type, and one-pair Oshi's communication is possible between ', and a master and a plurality of slaves. Piconet Instead of the ability to communicate with every slave in A, it is data volume. The effective communication speed of each slave may change with the number of slaves. S C 0 link It is used, A C L-linking and making it intermingled. It can also carry out.

A Slave with which one master can communicate simultaneously in a C L link It becomes by seven by a number and the maximum. However, one Piconet It is Establishment within A. The A C L link which can carry out a law is only one to each slave, one a plurality of applications with the o 1 One slave with which a slave cannot set up a plurality of A C L links at once -- Cash In order to operate A the application of a higher rank -- pro -- carrying out Tocol multiplexing -- Must It is an important point. As long as there is no specification in particular, in communication with a master and a slave, they are and single Throttling. A C L of ♪. Ke is used. A slave Multi-Throttling A C L bucket of ♪ In order to transmit A, it is a mass beforehand. The permission from the evening is needed. A master is Multis from a slave. A lock A C L Packet of ♪ Although the Request to Send of A is refusable, it is friction mark 1 The. The Request to Send from a master must be accepted.

as opposed to a master and a slave -- multi-Throttling the upper limit of ♪ -- connoisseur Knowledge is carried out -- multi-Throttling A C L bucket of Whether or not [ transmitting A ] -- A Loew's judgment is left. A C L Packet transmitted from a master on the other hand Single slot or multi-Throttling It is [ all ] Ma whether it is ♪. In order to be dependent on judgment of the A evening, slaves are all the multi-Throttling. Top pack It is always necessary to prepare reception of ♪.

A C L⁰In -- singles Multi-Slot -- constant -- Being different from Righteousness and the 1st which it divides roughly into and is provided with the following three bucket correspondence procedures are asynchronous communication methods (Asynchronous transfer). The 2nd is a Aisochronous communication method. (Isochronous transfer) With and the 3rd are simultaneous transmissive communication methods (Broadcast transfer).

An asynchronous communication method and the usual bucket Communication for transmitting and receiving ♪ It is a method. the access speed of data, and Piconet The friction mark which exists in A -- Butrahi Park by degradation of Amount communication line quality A -- resend It changes with When.

Drawing 1 4, the same Piconet Three slaves in A (slave 1 and 2 3) It is an example in the case of communicating by an asynchronous communication method. the mass evening from -- as opposed to each slave 1-2-3 -- order -- A C L Packet -- transmission -- Re and its A C L Packet It is reception from Slave which received A to a master. Packet of a check A is returned.

A, such as one Wow"" Diode evening and a video data Tree Moody It is a A C L bucket about Tha. It may transmit by the asynchronous communication method of ♪. thus, A Case where one Tori 1 Mude evening is made to transmit by an asynchronous communication method every -- A C L Packet making the Thailand Mus evening Ump add to ♪ -- receiving side A It enables it to secure the continuity of A trim data.

A Isoku mouth eggplant communication method and time Throttling decided beforehand Term of A Within between, it is certainly a bucket from a master to a slave. Method with which ♪ is transmitted It is. Minimum delay of the data transmitted in this method is secured. It can carry out. Aisok In the case of a loss communication method, they are a slot interval and maximum Po 1 Li. As Tongue time, it is a Isoku mouth eggplant communication method. Before making communication start, it agrees between a master and a slave. There is necessity.

a master receives a slave -- compulsory -- maximum Poli It is specification about a Tongue interval. it can carry out -- again -- isochronous communication method from a slave A setting demand is refusable. however, mass from a slave as opposed to the evening -- maximum Poli specification of a Tongue interval cannot be performed -- the setting demand of Aisochronous communication cannot be performed, either.

Drawing 1 5, eye It is between a master and a slave with a Soku mouth eggplant communication method. It is an example in the case of communicating. this figure -- 1 The maximum Po -- as [ show / in 5 ] -- Li carrying out A C from the mass evening within a Tongue interval -- bucket A -- friction mark 1 The -- Transmission is carried out -- that A C L bucket Packet of a reception check immediately after the slave which received A receives A -- master It has been made to return.

A simultaneous transmissive communication method and bucket It is zero about the slave identifier in Hedda. It is set up by carrying out. Thereby, they are all the slaves from a master. It receives and is a simultaneous transmissive communication bucket. A can be transmitted. The same Pake Bucket of a reception check of as opposed to it with the slave which received Toto is not transmitted. To instead of [ to which a slave does not perform a reception check ], it is a master. Simultaneous transmissive communication bucket ♪ is transmitted continuously two or more times. Two or more of this times Send Before performing the number of To times, and simultaneous transmissive communication, a master receives all the friction mark 1 A. It is necessary to notify.

Drawing 1 It is Piconet with 6 and a simultaneous transmissive communication method. He is a connoisseur to all the slaves in A. It is an example in the case of performing Trust. this figure -- 1 it sets to 6 -- The in a slave Kettle the part which gave X seal at the time of reception of ♪ -- slave at that time Bucket The example when A is not able to be received is shown and the said news can be certainly carried out to all the slaves by N BC time repetition transmission being carried out. It is made like.

Drawing 1 7 is S C 0 link. A A C L link is used together and used. It is a figure showing the example of communication. At this example, it is a S C O bucket in a S C O link. A is transmitted with a constant period between a master and slave 1. In the situation which is, it is a A C L bucket from the mass evening at any time to three sets of slaves 1, 2, and 3. ♪ is transmitted. bucket for simultaneous transmissive communication A -- just -- Predetermined Repeat repeatedly transmission is The(ed) and carried out.

Next, blue The transition state in Tooth is explained. This gentleman The transition state in a formula is involved in communication. Fa 1 A of a three-stage, and To of a terminal Low-power-consumption Moh concerning expense electric power It comprises Do. It is involved in communication.

Fa 1 A of a three-stage awaiting, if it carries out -- Phase and synchronous establishment Hue 1 it is divided into A and a communication phase -- again -- low-power-consumption Mode -- Park mode and Hold mode and Sniff mo There are three kinds of Dos. Drawing 2 8 is a figure showing the example of a change state -- Transition to the state which showed by the arrow There is Transfer.

It awaits, and comprises phase (S 1 1) and one processing state, and they are and what kind of bucket. It is Fa 1 A to which transmission and reception of ♪ are not performed, either. Communication Li immediately after turning on a terminal It is a terminal when An is cut. It awaits and is in a phase. There is no difference in this role concerning [ in / await and / Fa 1 A ] a master and friction mark 1 The.

It asks at synchronous establishment Fa 1 A, calls with (S 1 2), and comprises two kinds of (S 1 3).

An inquiry is Piconet. It is a processing state of one step of The which establish the synchronization in A and which are performed for accumulating. The first terminal to try to communicate and waiting It certainly changes to an inquiry the receptacle back.

A call is Piconet. Although a change state is fundamentally carried out from an inquiry by the processing state of two steps of The which establish the synchronization in ♪ and which are performed for accumulating, It is Piconet at letter-of-inquiry voice. The 1st-step processing of the synchronous establishment in A is already The end. When you have completed, change from a waiting receptacle to a call directly. Tease.

from which the role differs clearly with a master and a slave in an inquiry. the slave exists in the master in this processing state, and the circumference whether -- irrespective of -- continuing -- it is a blow about I Q bucket ♪ docast is carried out. When the slave in the processing state of an inquiry to the circumference exists, it is a I Q bucket. Whenever it receives A, it is a slave to a master. It is a F H S bucket in order to tell the attribute. A is transmitted. This F H S Ha ° Kettle By ♪, a master is A of a slave. A dress and clock It can know.

Drawing 2 The master and slave in 9 and this letter-of-inquiry voice carry out. It is a figure showing processing. First, Drawing 2 Like and center which are shown in the left-hand side of 9 A master is a I Q bucket. If A is transmitted, Drawing 2 it is shown in the right-hand side of 9 -- as -- the slave of that circumference -- F H S Packet This Yo that transmits A to a master The master which is in an inquiry obtaining, and many and unspecified friction marks 1 A F H S packet will be received from The.

Here, a plurality of slaves are specific I Q buckets simultaneously. It is F H S Packet to ♪. Transmitting A poses a problem. simultaneous -- a plurality of F H S buckets the time of A being transmitted -- bucket the collision of ♪ occurs -- mass the evening is transmitted -- F H S Packet Intermediary Cause which cannot judge A. Bull 1 A It is a F H S bucket in order to avoid such a collision in The source. In the case of transmission of ♪, it has been made to carry out random time back off. that is, the first IQ Packet to receive a slave as opposed to A -- the mass evening -- F H S Packet is not transmitted -- after that -- random time Ba while carrying out Off -- I Q bucket Reception of A is interrupted. then, friction mark 1 The -- IQ bucket reception of A is resumed -- the next -- I Q bucket It is reception about ♪. immediately after [ carrying out ] -- F H S bucket A is transmitted to a master. A slave is F H S Packet. When A is received, it is I Q Packet again. Random in reception of ♪ Time Back off You make it interrupted while carrying out. Henceforth, it is this operation. It repeats.

Drawing 3 Processing with master in 0 and this inquiry, and slave It is a figure showing an outline. A master is a F H S bucket. It is Acceptance without an error about A. In order not to notify a slave that Trust was able to be carried out, it is in the state of an inquiry. A certain slave is a F H S bucket. It will be in a state [ having transmitted A ]. It keeps. However, the same I Q Packet is repeated and it is The for a definite period of time [ a certain ]. Low Dokyu Since A is carried out, masters are a plurality of F H S buckets for Each friction mark of an inquiry processing state - every The. A will be received. After all, it is F H S Packet by continuing an inquiry for a definite period of time [ a certain ]. Transmission and reception of A The certainty of Trust is improved.

Also in a call, he is an intermediary with a different role with a master and a slave. It is. it asked in this processing state, came out, and transmitted and received ; F H S bucket based on the information on ♪, a master chooses the slave which communicates -- that A addressing to Loew -- I D Packet is transmitted. A master is I D Packet. When reception of A is checked, it is a F H S bucket to the friction mark 1 A. A is transmitted. It carries out. By this, Slave is A of a master. A dress and clock It can know. . I D bucket transmitted and received here ♪ and F H S bucket Access of Toco 1 It calls to Do and is Access co 1. Do is used.

Drawing 3 Master in 1 and call Processing operation which a slave performs The outline is shown. Drawing 3 Like and mass which exists at center which are shown in left-hand side of 1 The evening is I D Packet. By transmitting to a slave, a slave receives A. A check is notified. Drawing 3 Like and the master which are shown in the right-hand side of 1 are F H S buckets. By transmitting A to a slave, a slave is a reception check. It notifies.

It is as different as the processing to many and unspecified slaves in an inquiry. In Ri and a call, processings are exchanged between a specific slave and a master. To. It is a bucket at 1 to 1. A master and a friction mark since ♪ can be transmitted and received 1 The can be processed while checking the transmission and reception.

I D bucket from the mass evening the slave which received A, and a master -- said -- I D Packet of 1 A is transmitted and a reception check is notified. Next, master It is F H S Packet to a slave. A is transmitted and it is its A. A dress and Cros It is A about A. Loew is notified. a slave and this F H S packet if it receives without an error -- I D Packet is transmitted to a master -- that Acceptance It is considered as Confidence confirmation. It unites with the processing which asks and comes out at this time, and is Piconet. A required for the synchronization in A A dress and The It means that it was mutually exchanged between the master and the slave in the information on a lock.

Drawing 3 Place of example between master in 2 and call, and slave It is a figure showing Reason.

Drawing 2 It has a communication connection phase, and connection (S 1 4) and data transfer (S 1 5) which were shown in the state transition diagram of 8. this communication connection Fa 1 In the -- pass a synchronous establishment phase -- a master and a slave -- Piconet Inside of ♪ it synchronizes -- it is a phase which can perform actual communication. In the state of connection, it is a data bucket. Transmission and reception of ♪ are not performed. This Sometimes being transmitted and received and communication Li Control The for setting up Kitchen and security-related control Packet and low-power-consumption Moh To Do Related control Packet It is limited to A etc.

On the other hand, in the state of data transfer, it is a data bucket. Transmission and reception of ♪ approve. It is carried out. pass a synchronous establishment phase -- case where it changes to connection for the first time fundamental -- processing of connection attestation and encryption, between a master and a slave If it does not complete, it cannot shift to data transfer. Master in connection The role of a slave, and control Packet managed there It changes with contents of A.

Data bucket in one De evening transmission To transmission and reception of ♪, they are a master and a friction mark. -- It is carried out in accordance with the rule of The and time Slot. data Cong in a terminal when the terminal by transmission cuts communication fatty tuna -- as opposed to -La -- Ha 1 Reset -- and the change state of the terminal is carried out for awaiting from De-- evening transmission at a It was case.

Low-power-consumption Moh The shape of low power consumption of the terminal which changes from connection with De mo which provides voice Do is said. This low-power-consumption Moh In Do, it is a park. Mode (S 1 6) and hole Mode (S 1 7) and Sniff mo There are three kinds of Dos (S 1 8).

Park mode and Moh peculiar to a slave it is Do -- being established by connection Piconet Low-power-consumption Moh which maintained the synchronization in A It is Do.

Hold Moe both Do the Smarter evening and a slave can shift -- low -- Power consumption Moh it is Do -- Piconet established by connection It is maintenance about the synchronization in A. it carries out -- and Slave discernment which was given from the master in the case of the slave A 1 holding a child It is Do.

Sniff mode and low-power-consumption Moh peculiar to a slave it is Do -- Ho 1 Rudomo That it is the same as that of the case of Do, and Picone which established the slave by connection the synchronization in Tut is maintained as it is -- slave Identification given from the master Moh holding another child It is Do.

blue it sets to Towe 1 A -- Piconet the inside of A -- a master and Special Between the slaves of a law, master and slave conversion can be performed. To -- it is made like.

Security performed by the connected state of communication connection Fa 1 A which divides roughly and has processing of attestation and encryption of 2 as related processing. A permission judgment of the connection is made among as specific in attestation processing partners as itself. They are things. It says protecting data while encryption processing and a one are communicating so that it may not be intercepted by the third party.

Bull 1 Security of Tooth It is a pipe at the concept called link key. Reason is carried out. between a link key and a certain specific 2 terminals -- each -- it is -- security of 1 to 1 o which is one Parame evening to manage -- this Li Intercourse 1 must not be indicated by the third party.
