The mode of applying is explained in detail.However, it will be understood by those skilled in the art that in each embodiment of the present invention,
In order that reader more fully understands the application and proposes many ins and outs.But even if without these ins and outs and base
Many variations and modification in following embodiment, each claim of the application technical side claimed can also be realized
Case.
The first embodiment of the present invention is related to a kind of method for sending information, has sequence number applied to information band and can be by transmission
Order reaches the communication system of receiving terminal, and described information is according to Dm channel link access protocol LAPDm agreement division information frames, institute
State information frame number M be more than or equal to 7 be less than or equal to 11 and last information frame shared by spaces be a byte, the M
For positive integer.Idiographic flow as shown in figure 1, including：
S1, pre-establish the corresponding relation that the information in information frame only containing a byte puts in order with information frame.
When there is the application layer that packet comes self terminal or network, the packet can pass through terminal or the application layer of network
And protocol layer, several a certain size protocol data bags are then sent to by network or terminal, network or end by physical layer
After the physical layer at end receives packet, packet can be split.At present, splitting datagram most efficient method is profit
Application layer data packet is split with LAPDm information frames.In the method, an information frame has 21 bytes, wherein preceding 3 bytes
For filling control information, behind 18 bytes be used for filling data message, i.e., the effective information that each LAPDm information frames are sent
Size be 18 bytes.Example, it is assumed that the length for carrying out a short message of self terminal is 109 bytes, according to LAPDm information frames
Feature, after the packet of the short message reaches the physical layer of network or terminal, physical layer can be split to packet.Due to
109=（18*6+1）, therefore, the length can be split as 7 information frames altogether by the physical layer of network for the short message of 109 bytes,
Wherein, the size of the effective information of preceding 6 information frames is 18 bytes, and the size of the effective information of the 7th information frame is 1
Byte.
Because LAPDm information frames have the characteristics of i.e. stop-and-wait, that is, after sending an information frame, the frame must be waited until
Confirmation return after, just may proceed to send next frame.This mode can ensure the transmission order and receiving terminal of transmitting terminal
Reception order be identical.Therefore, the present invention utilizes the different arrangement modes of each LAPDm information frame number, so that it may
To represent the information of a unnecessary byte, as long as recipient receives such a order, it is possible to parse this most
The information of the latter byte, do not have to thus retransmit the LAPDm information frames for only including a byte.

Example, it is assumed that the transmission order of 6 information frames is（1,2,3,4,5,6）, it is with the transmission order of information frame（1,
2,3,4,5,6）To represent the information of such a bytes of 0x00；Assuming that the transmission order of 6 information frames is（1,2,3,4,6,5）
It is with the transmission order of information frame（1,2,3,4,6,5）To represent the information of such a bytes of 0x01.
Information frame number in table 1 puts in order may be considered a kind of mapping pass with the corresponding relation of a byte information
System, the mapping relations can be realized by array set in advance or program.Example, the mapping relations can be with following
C code realize.
It is noted that in the present embodiment, illustrated so that N values are 6 as an example, i.e., it is continuous with 6
The different arrangement modes of the sequence number of information frame, represent a byte information, the arrangement mode of the sequence number of specific information frame with
The corresponding relation of one byte information is as shown in table 1.But in actual applications, N can also be taken as 7 or 8, not go to live in the household of one's in-laws on getting married one by one herein
State.
S2, the corresponding relation according to the information inquiry of last information frame, obtain and last described letter
The information frame that the information of breath frame is corresponding puts in order.
Example, the length for carrying out self terminal is 109 byte, one short message, can be short by this in the physical layer of terminal
Letter is split as 7 information frames, and the effective information of preceding 6 information frames is 18 bytes, and the 7th information frame is last information
The effective information of frame is 1 byte.
For step S2, specifically, assuming that the information of last information frame of the short message is compiled as when sending
0x7B, inquiry table 1 is understood, when the information of last information frame is 0x7B, the information frame of the information put in order for（2,1,
3,5,6,4）, i.e., for 6 information frames sequence number according to first send the 2nd information frame, retransmit the 1st information frame, then
Send the 3rd, the 5th, the 6th, finally send the 4th information frame order come represent information be 0x7B information frame.
S3, arbitrarily select N number of continuous information frame, the N is the positive integer more than or equal to 6 and less than 9, according to inquiring about
To described information frame put in order and send N number of continuous information frame successively.
Assuming that N (S) serial number 3 of first information frame of the short message when sending beginning, because the short message is split as
Totally 7 information frames, and information frame number N (S) is the number that mould is 8, therefore, the information frame number N (S) of the short message is（3,4,5,
6,7,0,1）.
Specifically, any 6 continuous information frames of selection, by the transmission of described 6 continuous information frames sequentially with it is described
Putting in order when obtained information frame is sent is corresponding.Because the short message is divided into 7 information frames, therefore, the short message
In information frame, 6 continuous information frames are selected there are two kinds of systems of selection, the first system of selection is（3,4,5,6,7,0）, second
Planting system of selection is（4,5,6,7,0,1）.Present embodiment assumes that the method for 6 continuous information frames of selection is first method, i.e.,
The information frame serial number 3 of 1st information frame, the information frame of the 6th information frame of information frame serial number 4 ... of the 2nd information frame
Serial number 0.Putting in order when the transmission order of described 6 continuous information frames is sent with the obtained information frame is relative
Should, when the information frame obtained due to step S2 is sent put in order for（2,1,3,5,6,4）, therefore, obtained according to inquiry
Described information frame puts in order to be sent described 6 continuous information frames and is specially successively：（4,3,5,7,0,6）, i.e., the 1st transmission
The information frame of serial number 4, the 2nd send sequence number for 3 information frame ... ..., the 6th send sequence number for 6 information frame.
In addition, the described information frame obtained according to inquiry puts in order and sends N number of continuous information frame successively
Including：Flag bit is set in described information frame, and the flag bit is used to indicate that described information frame is the institute obtained according to inquiring about
Information frame is stated to put in order the information frame being transmitted.
Due to including control byte Spare in the LAPDm information frames, the byte does not have practical use at present, therefore
Spare bytes can be revised as to PRO_IND, and set the PRO_IND value be 1 be used to indicating described information frame be according to
Obtained described information frame is inquired about to put in order the N number of continuous information frame being transmitted；The value for setting PRO_IND is 0
For indicating that described information frame sends described information frame for the continuous principle of information frame number.In actual applications, can basis
Need that the value is adjusted flexibly.
Particularly, in order to distinguish the method for sending information of method for sending information in the prior art and the present invention, the present embodiment
Provide that method for sending information of the prior art is common sending mode, it is specified that the method for sending information of the present invention is special transmission
Pattern.
It should be noted that in the control information of each information frame generation, the value of the M bit in the 2nd byte for 0 or
Person 1, and when the value of the M bit is 0, the information for representing to be passed only is made up of an information frame；If the information being passed by
A plurality of information frame is formed, then the M bit of last information frame of the information frame that the information is split will be set to 0, remaining letter
The M bit of breath frame will be set to 1.In the present embodiment, due to last information frame of the serial number of information frame serial number 0, because
The M bit of the information frame are arranged to 0, the M bit of remaining information frame are arranged to 1 by this when sending the information frame.
Assuming that form when sending information is（N (S), PRO_IND, M bit),）Then the transmission order of the information is（（4,
1,1）（3,1,1）（5,1,1）（7,1,1）（0,1,0）（6,1,1））, then transmitting terminal is according to described in above-mentioned transmission order successively transmission
Information frame.
It should be noted that often sending an information frame, transmitting terminal can all open a T200 timer, if T200 surpasses
When after still without the confirmation from receiving terminal is received, transmitting terminal can resend the information frame for not receiving confirmation, herein
Transmitting terminal will not send new information frame before.
Embodiment of the present invention in terms of existing technologies, in transmitting terminal, arrange by the information and information frame for establishing information frame
The corresponding relation of row order；Then the corresponding relation according to the information inquiry of last information frame, obtain with it is described
The information frame that the information of last information frame is corresponding puts in order；N number of continuous information frame is arbitrarily selected, the N is big
In the positive integer equal to 6 and less than 9, being put in order according to the obtained described information frame of inquiry, it is described N number of continuous to send successively
Information frame.So, transmitting terminal can not have to last letter that an information frame sends only one byte is used alone
Frame is ceased, reduces the burden of communication network, improves the utilization rate of Internet resources.
Particularly, when the information frame that the packet is split is more than 7, and in last information frame being split
Information be a byte, the sending method of the packet is：The 6 continuous information is sent using special sending method
Frame, i.e., described 6 continuous letters are sent according to putting in order for the corresponding information frame of the information of last information frame
Frame is ceased, remaining 3 information frames are sent using common sending method.
Example, it is assumed that the length for carrying out self terminal is 145 byte, one short message, can be short by this in the physical layer of terminal
Letter is split as 9 information frames, and the effective information of preceding 8 information frames is 18 bytes, and the 9th information frame is last information
The effective information of frame is 1 byte, then the specific method for sending 9 information frames is：Assuming that the short message is being sent when starting
N (S) serial number 3 of first information frame, because the short message is split as totally 7 information frames, and information frame number N (S) is mould
For 8 number, therefore, the information frame number N (S) of the short message is（3,4,5,6,7,0,1,2,3）, then perform step S2, it is assumed that
Information after last information frame after being split of the short message is encoded is 0x7B, and inquiry table 1 is understood, when last letter
Cease the information of frame when being 0x7B, the information frame of the information put in order for（2,1,3,5,6,4）, step S3 is then performed, this is short
In the information frame of letter, 6 continuous information frames are selected there are two kinds of systems of selection, the first system of selection is（3,4,5,6,7,0）,
Second of system of selection be（4,5,6,7,0,1）, the third system of selection is（5,6,7,0,1,2）, the 4th kind of system of selection be
（6,7,0,1,2,3）.Present embodiment assumes that the method for 6 continuous information frames of selection is first method, i.e. the 1st information frame
Information frame serial number 3, the information frame serial number 4 ... ... of the 2nd information frame, the information frame serial number 0 of the 6th information frame.By institute
State when the transmission orders of 6 continuous information frames is sent with the obtained information frame put in order it is corresponding, due to step
When information frame that S2 is obtained is sent put in order for（2,1,3,5,6,4）, therefore, the described information frame obtained according to inquiry is arranged
Row order sends described 6 continuous information frames and is specially successively：（4,3,5,7,0,6）, i.e., the 1st send sequence number for 4 letter
Cease frame, the 2nd send sequence number for 3 information frame ... the 6th send sequence number for 6 information frame.
For the information frame that remaining 2 N (S) are 1 and 2, it is transmitted using common sending mode.
Second embodiment of the present invention is related to a kind of message receiving method, has sequence number applied to information band and can be by transmission
Order reaches the communication system of receiving terminal, and described information is according to Dm channel link access protocol LAPDm agreement division information frames, institute
The number M for stating information frame is more than or equal to 7 and is less than or equal to 11, and the space shared by last information frame is a byte, the M
For positive integer, idiographic flow as shown in Fig. 2 including：
The corresponding relation that the information of S1, foundation and transmitting terminal identical only containing a byte puts in order with information frame.
Described information frame puts in order is referred to table in the embodiment of the present invention one with the corresponding relation of the information of information frame
1.Mapping relations in the table can be realized by array set in advance or program.Example, the mapping relations can be with
Realized with following C code.
S2, N number of continuous information frame is received successively.
Because the information frame that receiving terminal receives both had included what transmitting terminal sended over according to common sending method, include again
Transmitting terminal sends over according to common sending method, and therefore, the receiving terminal often receives an information frame, can check first
Flag bit in the information frame received, come the information frame for judging to receive whether it is according to described according to the flag bit
Described information frame in corresponding relation puts in order the information frame being transmitted.Example, the described information received can be checked
Whether the value of the PRO_IND bytes in frame is 1.When the value of the PRO_IND bytes in the information frame received is 1, table
It is the information frame sent under special sending mode to show the information frame;Then described information frame is received according to special sending mode：
RR message is sent to transmitting terminal, the message informs that the transmitting terminal receiving terminal has been completed to connect the information frame for receiving terminal
Receive, now, transmitting terminal can be carried out have sent for next information frame.
When the value of the PRO_IND bytes in the information frame received is 0, it is under general mode to represent the information frame
Information frame transmission, now can receive described information frame according to common sending mode to the information frame received：First,
Judge described information frame number N (S) legitimacy.The method of the legitimacy for judging information frame number N (S) is judges this
The value for the N (S) whether the described information frame number N (S) received value receives than last receiving terminal is big by 1, only when this
The described information frame number N (S) received value it is bigger than the value for the N (S) that last receiving terminal receives 1 when, what this was received
It is legal that the sequence number N (S) of information frame is only.When the sequence number N (S) of this information frame received is legal, to transmitting terminal
RR message is sent, the message informs that the transmitting terminal receiving terminal has completed the reception to the information frame for receiving terminal, now, hair
Sending end can be carried out have sent for next information frame；When the sequence number N (S) of this information frame received is illegal
When, send REJ to transmitting terminal（Reject, refusal）Message.
Receiving terminal is cached the information frame received, and judges the value of M bit in described information frame for 0 simultaneously
Information frame before all information frames whether all receive.Specifically, M bit value is in the judgement described information frame
The method whether all information frames before 0 information frame all receive is：All information frames that receiving terminal is received
It is ranked up according to information frame number, using the information frame number that the value of the Mbit is 0 as last information frame, then sentences
The information frame number that the information frame number that the value for all M bit that disconnecting receiving end receives is 1 and the M bit value are 0
It is whether continuous, when all equal consecutive hourss of information frame number, before the value for showing M bit in described information frame is 0 information frame
All information frames all receive；Otherwise, the value for showing M bit in described information frame is all before 0 information frame
Information frame does not receive all, and all information frames before the value of M bit in described information frame is 0 information frame are not complete
When portion receives, the LAPDm information frames of Next Sequence are continued to.
S3, the sequential query described information frame of the N number of continuous information frame received according to puts in order and information
