Description

A kind of dictionary information synchronous method, device and equipment
Technical field
The present invention relates to communication technical field, particularly relate to a kind of dictionary information synchronous method, device and equipment.
Background technology
Operator, by being analyzed the data of transmission in network, finds inside the packet of user's transmitting-receiving, And there is substantial amounts of duplicate message between packet, i.e. exist some high frequencies occur long message field (with It is referred to as down high frequency field), the source and target IP ground in wrapping such as IP (Internet Protocol, Internet protocol) Location, the source and target port numbers in TCP (Transmission Control Protocol transmission control protocol) bag Etc., user sends duplicate contents in message etc..
A kind of existing compression method is as follows: before sending data, and compression end identifies the high frequency word that high frequency occurs Section, and substitute high frequency field, to reach the purpose that packet to be sent is compressed with special short coding. Solving pressure side, can be according to the special short coding (hereinafter referred to as field number) being obtained ahead of time and high frequency field Between dictionary mapping relations (in such as decompression dictionary each high frequency field correspond to a special short coding I.e. field number, the form of expression of this field number can be index value Index), original before recovering compression Information.
Said method relates to the form of a kind of compressed package: comprised by compressed package: packet header and payload (effectively carry Lotus) two parts.
Wherein, payload part is for (also may be used by initial data and the special short field for replacing high frequency field It is referred to as field number) composition;
Above-mentioned header part may comprise following information:
A, Type territory: whether instruction current data packet contains by compressed content;
B, Packet Length (data packet length): the total length of instruction payload part;
C, Number of Compress subheader (compressing the number of sub-header): Compress subheader Number, each subheader (sub-header) correspond to a high frequency field compressed;
D, Compress subheader, comprises following information in each subheader:
Index territory: by the field number in dictionary corresponding to squeezing characters string;
Offset territory: by squeezing characters string side-play amount of distance payload original position in payload;
It should be noted that subheader may also contain following information:
Length territory: the length of the character string compressed;Longer for dictionary medium-high frequency character string, and only have A beginning part occurs in the situation in the packet compressed.It should be noted that Length territory is optional Field;
Dict Setup territory: whether instruction present field is set up for dictionary;When compression starts, solve pressure side also Being not set up decompression dictionary, now, compression end needs to transmit dictionary information to solving pressure side.When high frequency field is first Secondary occur in compression end pass to solve pressure side data in time, compression end decompression dictionary is set up instructions field arrange For " dictionary foundation " (such as taking 0 mark with 1bit).Now compress the instruction of the Offset territory in sub-head to be pressed Contracting character string is the side-play amount of distance original position in payload, the length of Length territory instruction high frequency field, Index territory indicates the numbering corresponding to this high frequency field.When this territory is set to " non-dictionary foundation ", Index, Offset and Length territory is as described above.Dict Setup territory is Optional Field.
The process of setting up of high frequency dictionary has two kinds of common approach:
Scheme 1: transmit dictionary information while data are transmitted
Seeing Fig. 1, the payload of compression end raw data packets pending includes: abcdefg, wherein " bcdefg " The high frequency field identified for compression end, this high frequency field is write high frequency dictionary, and numbered 5 by compression end.
Seeing Fig. 2, the data after data are encoded by compression end are as follows:
T (Type territory): instruction current data includes by compressed content;
L (Packet Length territory): the total length of instruction payload part, 8byte;
N (Number of Compress subheader territory): value is 1;
In Subheader, information is as follows:
Dict Setup territory: 0, mark corresponding data string is original character string, for setting up high frequency in solution pressure side Dictionary;
Offset territory: 1, after instruction high frequency field is positioned at the 1st character of payload part;
Length:6, instruction high frequency field length is 6byte;
Index:5;The field number indicating this high frequency field corresponding is 5.
After receiving this packet, solution pressure side is taken out character string bcdefg from payload and is charged to decompression dictionary, right The index answered is 5.Meanwhile, the data that payload part is transmitted as this, pass to high level.
Scheme 2, use dedicated signaling transmission
See Fig. 3, it is shown that compression end conciliates the special signaling procedure of pressure side, for the foundation of decompression dictionary. Compression end conciliates pressure side can set up decompression dictionary by the message of definition chain of command.As shown in Figure 3.As Really the data compression between UE and eNB of this compression process, then can utilize dedicated signaling to set up solution Pressure dictionary.In this process, renewal set up by user data transmission and dictionary is two independent processes.If Set up/update decompression dictionary based on this kind of mode, then dictionary information need not carry in user data, therefore, Compressed data packets need not be carried Dict Setup territory again.
Set up in renewal process at above two dictionary, packet loss once occurs, solve pressure side and will appear from mistake.
Mistake has two kinds of situations:
Situation 1: the dictionary information that compression end sends is for setting up a new Index and the mapping of high frequency field Relation, this information dropout can cause solution pressure side when decompression, find not by the Index of dictionary record;Cause solving Press unsuccessfully
Situation 2: the dictionary information that compression end sends is for updating reflecting of an existing Index and high frequency field Penetrate relation, this information dropout can cause solve pressure side decompression time, solving by out-of-date mapping relations of mistake Pressure;Decompression is caused to be made mistakes.
Caused because dictionary information is asynchronous solving extrusion it follows that prior art exists compression end reconciliation pressure side Wrong problem.

First embodiment
See Fig. 4, figure shows a kind of method that dictionary information synchronizes, specifically comprises the following steps that
Step S401, compression end send dictionary information to solving pressure side, and dictionary information includes: high frequency field and word The dictionary mapping relations of segment number.
Alternatively, compression end is to solving the packet after pressure side sends coding, and startup is used for calculating feedback time Intervalometer, the packet after coding carries dictionary information;Or compression end sends signaling bag to solving pressure side, And starting the intervalometer for calculating feedback time, signaling bag carries dictionary information.
Before sending data, compression end identifies high frequency field, and replaces with special short coding (field number) For this high frequency field, and by above-mentioned high frequency field and above-mentioned field number record tremendously high frequency dictionary, i.e. at height Dictionary can record the dictionary mapping relations of high frequency field and above-mentioned field number frequently.
Above-mentioned high frequency field refers to the long message field that high frequency occurs, such as the source and target IP address in IP bag, Source and target port numbers in TCP bag etc., user sends duplicate contents in message etc..
Above-mentioned field number is the special short coding that in high frequency dictionary, this high frequency field is corresponding, such as, index Index.Certainly it should be noted that the most do not limit the concrete of high frequency field and field number The form of expression.
Above-mentioned dictionary information can be that dictionary sets up information or dictionary updating information, and wherein information set up by dictionary For notifying that solution pressure side is set up information according to dictionary and set up decompression dictionary;Dictionary updating information is used for notifying decompression Dictionary mapping relations in decompression dictionary are updated by end according to dictionary updating information.
When dictionary information is dictionary updating information, after above-mentioned steps S401, compression end can by with field The state of the former dictionary mapping relations that numbering is corresponding is set to failure state.Such as: in high frequency dictionary, record has Field number " 5 " and the former dictionary mapping relations of former high frequency field " abcdef ", compile when establishing this field During the new dictionary mapping relations of number " 5 " and new high frequency field " abcdefg ", compression end can be by field number " 5 " are set to failure state with the state of the former dictionary mapping relations of former high frequency field " abcdef ".
Step S402, when compression end set feedback time in receive solve pressure side send feedback message time, The state of dictionary mapping relations is set to active states by compression end, and feedback message is used for having represented solution pressure side It is properly received dictionary information.
It should be noted that feedback time can be configured as the case may be in the present embodiment.Certainly may be used To be understood by, when the decompression packet that receives of termination or signaling bag include that multiple dictionary information is (the most multiple Dictionary mapping relations) time, if above-mentioned feedback message includes the confirmation numbering of dictionary mapping relations Time, the state of dictionary mapping relations all in packet or signaling bag is disposed as active states by compression end.
In the present embodiment, the state of dictionary mapping relations includes active states and failure state.Compression end is only Dictionary mapping relations according to active states are compressed processing, and solve pressure side also according only to the dictionary of active states Mapping relations carry out decompression.
In the present embodiment, feedback message includes: one confirms numbering or the multiple confirmation numberings converged, its In, a dictionary information confirming that the corresponding end that is extracted of numbering is properly received.
When feedback message includes a confirmation numbering, the state of dictionary mapping relations is arranged and makes a living by compression end Effect state, specifically includes: the state of the dictionary mapping relations confirmed corresponding to numbering is arranged by compression end For active states;Or compression end determines and a dictionary information confirming that numbering is corresponding;Compression end determine with Dictionary information is positioned at all dictionaries corresponding to all field number of same packet or signaling bag and maps and close System;The state of all dictionary mapping relations is disposed as active states by compression end;
When feedback message includes the multiple confirmation numbering converged, the state of dictionary mapping relations is set by compression end It is set to active states, specifically includes: compression end is by corresponding to multiple each confirmation numberings confirmed in numbering The state of dictionary mapping relations is disposed as active states.
Alternatively, in the present embodiment, confirm that numbered field number (such as Index) or packet are compiled Number (such as SN) or the numbering of signaling bag, be also not limited to this certainly.
Step S403, when compression end be not received by feedback time solve pressure side send feedback message time, Compression end resends dictionary information to solving pressure side.
Step S404, when compression end be not received by feedback time solve pressure side send feedback message time, Described compression end is by high frequency field and the state of the new dictionary mapping relations of field number, and and field number The state of corresponding former dictionary mapping relations is disposed as failure state.
Such as: in high frequency dictionary, record has the former dictionary of field number " 5 " and former high frequency field " abcdef " Mapping relations, establish again the new dictionary mapping of this field number " 5 " and new high frequency field " abcdefg " Relation, when compression end is not received by the feedback message solving pressure side transmission in feedback time, compression end can By the new dictionary mapping relations of field number " 5 " Yu new high frequency field " abcdefg ", and field number " 5 " are disposed as failure state with the state of the former dictionary mapping relations of former high frequency field " abcdef ".
