(11) the parameter setting is preserved in service end outage, stops the data communication between service end and the feedback end.
Below will further describe data receiving-transmitting method according to the present invention.
Known, data transfer direction comprises 2 kinds, uploads and downloads, and uploads to be meant that feedback end submits data to service end, and download is that service end sends to the feedback end data.
Usually, data volume is divided into Dan Bao and Duo Bao by size.The packet of single Bao Zhiyi fixed length just can complete transmission information.Many bags are meant and will be divided into a plurality of single bags, repeatedly transmit the data that could accomplish.
For improving communication efficiency, the communication between service end and the feedback end can be divided into 4 types: go up the leaflet bag, upload many bags, download single bag, download many bags.Guarantee that the reliable transmission of these four kinds of packets just can satisfy the demand of high density communication environment communication data communication real-time tranception.
For guaranteeing the packet reliable transmission to the other side, any packet has all required to receive correctly to be confirmed, promptly transmit 1 packet after; The take over party should reply data and receive; If there is not this to reply, transmit leg just should resend, and counts out up to success or after repeatedly attempting.
Owing to all send data simultaneously, having that the communication conflict causes all can't communication, so the mechanism that solves the communication conflict will be arranged.The present invention adopts host-guest architecture, and is the target of taking a message, and feedback end is a beacon with the order that service end is sent all, and feedback end does not initiatively send data, and service end requires to send out data and just submits data to.
Preferably, the mode that service end requires to send out data includes 2 kinds, and a kind is called the poll formula; Shown in accompanying drawing 4; It is characterized in that specifying the feedback end of certain particular number to submit data to by service end, feedback end is submitted data to service end successively according to the instruction sequences of service end.Preferably, polling mode has a kind of mode of texturing of raising the efficiency, and is that data are submitted on one group one group ground to, and we are group call mode, shown in accompanying drawing 5.The 2nd kind is called competitive mode, different with the poll formula shown in accompanying drawing 6, after service end broadcast type question (promptly to nonspecific feedback end question), as long as feedback end has data, can submit to.But need take this moment certain method of avoiding a conflict to submit data to.For example, shown in the accompanying drawing 6, if A3 number is submitted to data with A5 number at synchronization, produce data collision, then data are cancelled.
The polling mode conflict is few, but efficient is low, and competitive mode is exactly the efficient height, and above pattern respectively has characteristics, under high density communication environment according to the present invention, all can adopt in the communication data receiving/transmission method.
The realization of last leaflet bag, as shown in Figure 7, the flow process of last leaflet bag data is following:
Step 2, whether the feedback end inspection has data upload;
Step 3, feedback end is uploaded data;
Step 4 after service end is received data, is confirmed data to feedback end;
Step 5, whether inspection receives the affirmation from feedback end, if do not receive repeating step 3 otherwise get back to step 1.
Upload the realization of many bags
Upload many packet modes and have two kinds:
(1) usefulness discontinuous upward leaflet bag is repeatedly realized,
(2) many bag data have once been passed continuously.
For example: once pass the packet of a NK byte, implementation has 2 kinds of situation: a kind of is that service end requires to submit to many bags of certain type, and a kind of is that many bags are sent in the feedback end requirement, and 2 kinds of situation are all possible.
If feedback end require to send many bags, what we adopted is, the feedback end first to file passes many bags, and service end receives instruction with many bags again and do not stop to receive the flow process that finishes up to reception then.The request that the feedback end first to file passes many bags is in the service end inquiry, to submit to service end in the leaflet bag; The feedback end number record of bag were got off more than service end was uploaded application then, wrapped at appropriate time standby more as required more then and received the command reception data.
Many bags receive instruction and can adopt 1 to ask that 1 answers or 1 asks that the patterns that pass realize more.
Download the realization of single bag
Downloading single bag generally is that service end is sent out packet to the appointment feedback end, waits for that then the affirmation of feedback end is replied, otherwise sends out packet again.
Download the realization of many bags
Refer to disposable many bag data of downloading continuously, realize having 11 affirmations, pass two kinds of patterns of 1 affirmation more.
(1) 11 affirmation mode
Service end is the 1st bag of the packet of T to specifying the feedback end transmission types, waits for that then feedback end confirms to reply, and confiscates and confirms just to resend, and receives that affirmation just sends next bag, receives correct up to all packets.
(2) 1 affirmation modes that pass more
Service end is transmitted a plurality of packets continuously, for example transmits 16 packets earlier 1 time, and then inquires which bag 16 bags the insides have correctly received, and then resends the correct packet that receives, and then inquires correct situation about receiving.Because the number of times of inquiry significantly reduces, when specifying single feedback end to download, efficient improves about 1 times under this pattern.If broadcast type, all feedback ends of back can both receive correctly basically owing to repeat to send repeatedly, only surplus inquiry result's sequential, and the sequential of sending data significantly reduces, and efficient can increase many times.
