Description
Technical field
The present invention relates to the method that a kind of note transmits, the method that particularly a kind of note of specific expansion transmits.
Background technology
Nowadays, more and more universal along with mobile communication, exchanging by sending short message by mobile phone becomes a kind of more and more general communication way.Yet mobile phone can only send text message by note substantially, but note has the restriction of amount of capacity (according to GSM note standard, every SMS capacity is 140 bytes, be maximum 70 Chinese characters or 140 ascii characters), thereby mobile phone generally can't once send data beyond more contents or the text by note, such as common picture of mobile telephone, the tinkle of bells or the like.Formulated some standards in GSM 03.42 standard, yet this compression is only limited to single text message, and because its wall scroll text message compression ratio is lower, this standard is not supported generally still at present about note compression transmission.
There is the mobile phone products of some manufacturers to have own functions peculiar can send some the tinkle of bells or picture (for example Nokia and Sony), but because the employed standard difference of each manufacturer, such function is incompatible often between the mobile phone of different vendor, for example the user can send the tinkle of bells mutually by Nokia's mobile phone, but but can not send to these the tinkle of bells on the mobile phone of Sony.Information such as the picture that these mobile phones of while are supported, the tinkle of bells all are that strict format restriction and size restriction are arranged, and for example Nokia's mobile phone is only limited to the melody of the MIDI type of specific modification by the tinkle of bells that note sent.
In summary it can be seen that want at present to send special data message by note, mobile phone need overcome following difficulty: message volume restriction, compression ratio restriction and compatible problem.Therefore, we need a kind of above-mentioned shortcoming that overcome, and a kind of note transmission method that is applicable to all or most of mobile phones is provided, no matter the user uses is the mobile phone of what brand, can send special data message by this method.
Summary of the invention
In order to achieve the above object, the invention provides and a kind ofly transmit the method for arbitrary data information by extending message transmission capacity, this method comprises step: in transmitting terminal (A) judgment data type; (B) according to data type data are carried out preliminary treatment; (C) data after the preliminary treatment are compressed; (D) data after the compression are cut apart; (E) send divided data; At receiving terminal: (F) receive data; (G) data of cutting apart are recombinated; (H) data after the decompression reorganization; (I) judgment data type; (J) according to the data type restore data.This method has at first been carried out preliminary treatment according to different data types to data, has deleted the redundant information in the data, handles by special compression then, and data message is diminished as much as possible; Secondly, this method is cut apart transmission for bigger data, thereby the size of data can not be subjected to the restriction of message volume substantially.
Description of drawings
In order to understand other purpose of the present invention, feature and advantage better, should read following embodiment with reference to the accompanying drawings, the wherein identical identical assembly of label representative:
Figure 1 shows that the process that method of the present invention is handled data at transmitting terminal;
Figure 2 shows that divided data structure chart of the present invention;
Figure 3 shows that the process that method of the present invention is handled data at receiving terminal.
Embodiment
Method of the present invention mainly contains following step and forms: in transmitting terminal (A) judgment data type; (B) according to data type data are carried out preliminary treatment; (C) data after the preliminary treatment are compressed; (D) data after the compression are cut apart (segmentation procedure is only carried out) data length deducts the length of format header information greater than wall scroll note heap(ed) capacity when; (E) send data; (F) at receiving terminal: receive data; (G) data of cutting apart are recombinated; (H) decompressed data; (I) judgment data type; (J) according to the data type restore data.Next, we will carry out careful description to it.
Figure 1 shows that the process that method of the present invention is handled data at transmitting terminal:
A, judgment data type: generally speaking, we can be divided into three kinds to data type: text data, picture and sound.When the user is ready for sending data, mobile phone can be judged the data type that will send by several different methods.For example, according to user's selection: user's data type that selection earlier will send before sending data, mobile phone will be known the data type that will send easily like this.This is a kind of method, and in addition, the extension name of the data file that mobile phone can be selected according to the user is judged the data type that will send.For example, expansion by name jpg, gif are picture file, and expansion mid, wav by name are audio files or the like.
B, according to data type data are carried out preliminary treatment: for different data types, method of the present invention provides different processing methods, as much as possible with the size decreases of data.
For text data, mobile phone adopts the preliminary treatment based on dictionary, (such as: " going home " use " ^H " replaces, and " go home " use " ^h " replaces).Here mobile phone need have a common dictionary, and nearly thousand entry (about altogether 5k byte) just can play compression effectiveness clearly.At present, for most mobile phone, such memory space takies and can ignore.
For image data, mobile phone adopts the at user option processing that diminishes.Such as: the color to picture is cut down, picture diminishes, adopts interlacing scan resampling or the like.Diminish the handset displays type of processing, different selections can be arranged at destination.Because these quality of handling picture have certain influence, so mobile phone can be handled according to user's wish.Such as: user A need send the picture of a 16k look to user B, but the dimension of picture of considering the 16k look is bigger, so user A when sending, can come by the option of program the color of picture is cut down, and this picture is become 4096 looks from the 16k look send.This treated picture can only advance 4096 looks at most when arriving the mobile phone of user B to be showed, can not recover original 16k look.Adopt and top same principle and step, send after can handling the size of picture or readability, with minimizing of realization transmission data.
For voice data, mobile phone also can diminish processing, and the same with picture certainly, this step can be carried out according to user's wish, compresses such as the MP3 Processing Interface of possibility calling mobile phone system.The MP3 compression belongs to lossy compression method, still for the audio system of mobile phone, does not have the demand of high-fidelity, so we can suitably regulate compression ratio to realize the balance of maximum compression ratio and readability.
C, the data after the preliminary treatment are compressed: the data after the preliminary treatment, before the preliminary treatment, its size is little much relatively, and for the limited width of better utilization channel, mobile phone continues the data after the preliminary treatment are compressed.The compression here can be conventional arithmetic compression.Present general arithmetic compression all is based on dictionary, and all has different algorithms to revise.We can help the optimization of mobile phone feature on the principle of arithmetic compression.For example can design compression algorithm with reference to the thought of LZMA (Lempel-Ziv-Markov cha in-Algorithm) algorithm.Compression is handled can consider to comprise checking data, such as CRC check.
D, the data after the compression are cut apart: and through the preliminary treatment and the compression of front, the user wants the size of the data that send than little much before the preliminary treatment.If the size of data of this moment is less than the capacity (general restriction is 140 bytes) of note, Ya Suo step just can be omitted so.And if the size of data of this moment is greater than the capacity of note, so in order to send this data by the note channel, mobile phone need be cut apart these data, simultaneously divided data is added sequence identifier, can also add the data check position.
Figure 2 shows that the divided data structure chart.The start-up portion of data is a Data Identification, comprises compressing mark and sequence identification.Compressing mark can use 1 expression according to this method data processed, the normal data of 0 expression.For sequence identification is simplified the most, employing " group id "+" the first sign of segmentation "+" fragment sequence sign " shows jointly.Such as: 1100000100001000, have two bytes altogether, the data of first 1 expression back use this method to handle, second 1 these data of expression are article one data (are not article one data be designated 0), two of the back is to keep the position, ensuing these data of 4 bit representations belong to first group, and last these data of 8 bit representations are 8 at the sequence number of this group.Represent that thus one has 8 data.Ensuing data sequence number successively decreases, to obtain normal ordering.After the sequence identification is exactly the data content of note.Certainly, just example shown in Figure 2, as long as in fact satisfy the transmission condition, other various data structures all are available.For example, can add the data check position at last in data in order to transmit reliable data.
E, send divided data: according to the difference of type of cell phone, to the data transmission of encoding.For example, according to GSM SMS standard data are carried out the 8bit coding and send for GSM mobile handset.
Figure 3 shows that the process that method of the present invention is handled data at receiving terminal:
F, reception data: after mobile phone is received data, at first judge according to data are the first whether these data are the note of compressing, if this note first place is 0, illustrate that then this note is a normal short message, mobile phone will carry out normal process and demonstration to it.If this note first place is 1, mobile phone has dual mode to handle such special short message so: one, directly after the storage, manually call corresponding software by the user, and finish data processing; Two, receive note after, directly call related software automatically and finish processing by mobile phone OS.(the hardware and software extensibility of handset processes way of short messages and mobile phone is closely related.If the hooks technology that the operating system support software of mobile phone is commonly used, the note of this mobile phone is handled and can be used second method to finish automatically so; If the operating system of mobile phone is not supported the hooks technology, so just need the user manually to finish the processing of note.
G, the data of cutting apart are recombinated: according to the sequence identification of grouped data, mobile phone is arranged the data that receive, and according to data structure data extract is wherein come out, and recombinates.If find have note to lose by the sequence number carve information of note, then after wait timeout, to corresponding note request repeat.If data check is made mistakes, also will be to corresponding note request repeat.
Data after H, the reorganization that decompresses: this step is corresponding with step C, uses which type of compression method, is exactly to the data after the reorganization are carried out decompress(ion) here with corresponding decompression method.
I, judgment data type: mobile phone is obtained the type information of these data according to the information in the data after decompressing, and judges the data type of these data.
J, according to the data type restore data: known the data type of data, mobile phone just can recover the data that the user sends.For text type: mobile phone calls dictionary, and data are deciphered, and makes the user can directly check note; And for picture and voice data, the user can select to check/listen to or store.For the data of picture and sound type, diminish processing though before transmission, passed through, generally can not influence user's use, dwindling or the resolution reduction of picture do not have too big difference substantially on the screen of mobile phone.Voice data because the audio frequency range of mobile phone speaker is all less, is difficult to recognize any difference by after the reduction on mobile phone.
Described in this article embodiment is many some examples that use in the example of the present invention, and just as an example purpose but not enumerated as the purpose of restriction.It is apparent that, be that very conspicuous many other embodiment can be reached not departing under spirit of the present invention and the scope to those skilled in the art.
