Description
Technical field
The present invention relates to the communications field, relate in particular to data transmission system in a kind of communication system method of unifying.
Background technology
General communication equipment is made up of polylith veneers such as master control borad, business boards.Between the webmaster of communication system and the master control borad of communication equipment, exist message data between master control borad and the business board and communicate by letter.TLV (type, length and value) coding is a kind of digital coding mode commonly used in communication protocol, and it is the initial letter abbreviation of three English words in fact: Type (type), Length (length) and Value (value), wherein:
Type is in order to allow the implication of machine or procedure identification data, knows that these data are different from the function of other data and are numbered, and that is to say that Type represents a kind of implication of data;
Length represents the length of data, carry out with the integral multiple byte when transmission and deal with data, so the unit definition of length is a byte;
Value represents the value of data, just the content of data.
As seen, TLV coding is exactly a kind of coded system of coming the information that data of description itself will transmit by tlv triple (Type, Length, Value) in fact.Wherein the data length represented of TLV may be a fixed length, also may be elongated.
Usually when data being carried out the TLV coding, at first need to determine a TLV definition list, as shown in table 1.
Table 1
| Type (Type) | Length (Length) | Value (Value) | Implication |
| 100 | Unfixing | " Zhang San " | Name |
| 101 | Unfixing | " China " | Country |
| 101 | Unfixing | " U.S. " | Country |
| 102 | Unfixing | " Tsing-Hua University " | Institution of higher learning |
| 102 | Unfixing | " South China Science ﹠ Engineering University " | Institution of higher learning |
As can be seen from Table 1, the implication of these data of Class1 00 expression is the names with string representation, and length is fixing, and for example the value of certain 100 type TLV data is " Zhang San " etc.; The implication of Class1 01 these data of expression is the countries with string representation, and length is unfixing, for example " China ", " U.S. " etc.; The implication of Class1 02 these data of expression is the institution of higher learning with string representation, and length is unfixing, for example " Tsing-Hua University ", " South China Science ﹠ Engineering University " etc.
When communicating pair during by above-mentioned TLV coding transmission data, the transmit leg of data at first needs to preserve respectively an identical TLV definition list with the recipient, and table 1 for example then, carries out the transmission of TLV data according to step shown in Figure 1:
TLV data flow after step 2, data receiver are finished coding mails to the data receiver;
But in actual applications,, be a kind of data redundancy, in data transmission procedure, increased volume of transmitted data, thereby influenced data transmission efficiency, wasted interface-free resources as the TLV data of " 100 2 Zhang San ", " 101 2 China " these repetitions.

| 104 | Unfixing | Unfixing | Circulation |
This table comprises the type definition of each data, and comprising the definition of circular form TLV data, and the length of all types of TLV data is unfixing;
Wherein, the minimum data structure refers to have the minimum component units of some groups of data of same data structure, and it has type and value at least.
Certainly in other embodiments, this coding module also can be converted into the TLV data with minimum data structure in the some groups of data with same data structure to be sent respectively successively according to the TLV definition list, and judge through respectively organizing whether there are identical TLV data (being the identical data of T and V) in the data behind the TLV coding, if, then some groups of data are merged into a TLV data flow, subsequent operation is identical with above-mentioned example.
In the said system, the data receiver further comprises recipient TLV definition module 420, decoder module 430 and the receiver module 410 that connects successively, and as shown in Figure 4, wherein, receiver module 410 links to each other with data receiver.Below described each functional module is elaborated:
Recipient TLV definition module 410 is preserved with transmit leg and has been consulted the TLV definition list determined in advance, and this table comprises the type definition of each data, and comprising the definition of circular form TLV data, and the length of all types of TLV data is fixing;
When needs transmit following two groups of data, in the present embodiment, transmit leg realizes that process that data send as shown in Figure 5, comprises the steps:
(1) name: Zhang San; Country: China; Institution of higher learning: Tsing-Hua University;
(2) name: Zhang San; Country: China; Institution of higher learning: South China Science ﹠ Engineering University.
Wherein, the minimum data structure refers to have the minimum component units of some groups of data of same data structure, and it has type and value at least.
In the present embodiment, after transmit leg is the TLV data set with two groups of transmission data conversion respectively according to the TLV definition list, as can be seen, in these two TLV data sets, there are identical TLV data, be that type is 100 (being name), and data value is the TLV data of " Zhang San ", can be with the TLV data of this repetition as TLV data in the final data flow transmitted, in like manner, type is 101 (i.e. countries), and data value is the TLV data of " China ", can be used as another TLV data in the final data flow transmitted; And type is 102 (being institution of higher learning) in these two TLV data sets, but data value is respectively " Tsing-Hua University ", two TLV data of " South China Science ﹠ Engineering University ", then can be with them as circular form TLV data in the final data flow transmitted, wherein, first data are number of cycles in the value of circular form TLV data; Second data rises and is the different Value Data structure of each homotype; In the present embodiment, finish the data flow that forms behind the above-mentioned cataloged procedure as shown in Figure 6.
When the recipient received above-mentioned TLV data, its process comprised the steps: as shown in Figure 7
Step 720 judges whether there are circular form TLV data in this data flow, if enter step 730, otherwise enter step 750;
Step 730 reads first data in the value of circular form TLV data, and promptly number of cycles n shows that this TLV data flow obtains the initial data that the n group has same data structure after the decoding reduction;
In this embodiment, number of cycles is 2, show to comprise in this circular form TLV data that 2 types are identical but be worth TLV data inequality, and in other embodiments, also can be circular form TLV data definition one period information separately.
In other embodiments, above-mentioned all kinds of TLV data are all supported nested function, and promptly the data value of TLV data can further nested TLV data.
From above-mentioned implementation column as can be seen, take the data of 30 byte-sized in the prior art, after having adopted technical solution of the present invention, only need the TLV data of 25 byte-sized just can realize.In the middle of practical application, have the mass data of same data structure, if there is identical minimum data structure, then can reduce data redundancy significantly, reduce volume of transmitted data, save valuable interface-free resources greatly.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
