Method for the transmission of short messages

State of the art

p0001The invention relates to a transmission frame and a telecommunication device to a transmission frame according to the preamble of independent claims made.

p0002Short message services for the transmission of short messages are already known. The short message services are used to send a subscriber of a telecommunications network a short message without previously a telecommunications link must be set up for this. This is particularly in mobile radio systems of interest because there participants are often not attainable. Here incoming messages are stored by a network operator of the telecommunications network and received at a later time to the addressed subscriber. The participant is informed of the arrival of a certain for him instant message so that it can download these from the network operator.

p0003Example of a short message service is the Short Message Service (SMS) according to the GSM standard (GSM). This short message service sets a transmission frame for transmitting a short message of up to 160 7-bit ASCII text characters (ascii). A transfer of longer texts is possible by means of concatenated short messages. With the help of this short message service is also possible with simple mobile terminals a create and read the short message. Since, according to the GSM standard is intended for short messages only text transmission, would have in the transmission of binary data such as audio data, image data, or the like, these are converted to text format and converted back to binary format after receiving again.

ADVANTAGES OF THE INVENTION

p0004The transmission frame according to the invention and the telecommunication device according to the invention with the features of the independent claims have the advantage that at least two data fields are provided, that in the data fields data of a short message is stored and that in a first data field data of a first data format and in a second data field one from the first data format different second data format are stored. In this way, an instant message, the different types of data includes, transmitted in a single transmission frame. Thus can be different media, integrating such as text data, audio data and image data in a simple manner in a single short message so that a multimedia short message can be formed.

p0005A further advantage is that the transmission frame is not limited in its length, but that any data fields juxtaposed in the transmission frame can be transmitted.

p0006A further advantage is that a simple separation or downloading the data of a single data field or medium with text, audio or image data is made possible by the sequential arrangement of the data fields. Since that only the really required part of the short message needs to be downloaded from the network operator of the telecommunications network, to transfer capacity can be saved.

p0007The measures specified in the dependent claims, advantageous refinements and improvements of the independent claim 1 transmission frame are possible.

p0008it that the first data field in a first identifier is provided which characterizes the structure and / or content of the short message is particularly advantageous. In this way, a subscriber to whom the short message is addressed, particularly easy to be informed by transmitting only the first data field from the network operator of the telecommunication network to the addressed participants about the structure and / or content of the short message. Because this information can then be decided at the addressed subscriber, which parts or data fields of the short message they want to download from the network operator of the telecommunications network.

p0009Another advantage is that the first data field is limited in size to a predetermined value. Thus, a subscriber can be informed with limited capacity to receive short messages on the organization and / or the content of the entire short message by transmitting the first data field.

p0010A further advantage is that the total length of the short message is not limited.

p0011It is also advantageous that in at least two data fields, a respective data field-specific identifier is provided which characterizes the structure and / or the content of the corresponding data field. In this way also a message about the structure and / or the content of the entire short message generated by consolidating all data field specific identifiers and sent to the addressed subscriber, so that the first data field is not overly filled with identifying data, especially in the case of size limit.

p0012By data field specific identification of the addressed participants can be informed in more detail about this data field by the network operator and thus better adapted for example, a reproduction of the information transmitted with the data field to its playback options when downloading the corresponding data field.

p0013it is that the information stored in the first data field data is in a format accessible by all nodes of the telecommunications network data format is particularly advantageous. In this way, short messages mailable at least partially to all subscribers of the telecommunications network. In addition, all participants can present short messages are at least informed of it for the network operator, even if they can not read certain data fields intended for it short message.

p0016The second subscriber 65 a short message 5 is created for the first subscriber 60 and radiated with appropriate addressing via the telecommunications network 10 to the network operator 70th The network operator 70 stores the short message 5 and sends the first subscriber 60 a message, after which it is informed of the existence of a short message addressed to him. 5 This message can be the first subscriber 60, for example, sent, if the network operator 70 detects an activation of the first subscriber 60th Calls the first subscriber 60 upon receipt of said message the network operator 70 for transmission of the short message 5 on, the network operator 70 first sends a message that the first subscriber 60 informs about the structure and / or content of the short message 5 to the first participant 60th The first station 60 may then the short message 5 partially or fully downloaded from the network operator 70 so that the short message 5 is partially or completely transferred by the network operator 70 to the first party 60th

p0017In <figref idrefs="f0001">figure 2</figref> is shown the structure of such a short message. 5 The short message 5 is transmitted in a transmission frame 1 from the second subscriber 65 to the Telephone Company 70th The transmission frame 1 includes a first data field 15, a second data field 20, optionally a third data field 25 and a fourth data field 30. The first data field 15 comprises a first identifier 35 which identifies the structure of the short message. 5 In addition, 40 may be provided in the first data field 15, a second identifier that identifies the content of the short message. 5 The first identifier 35 and the second identifier 40 can also be combined to form a unique identifier, which characterizes the structure and / or content of the short message. 5 In the first data field 15 also data of a first data format are stored. In the second data field 20 data from a first data format different second data format are stored. In the optionally present further data fields 25, 30, data are also stored in a data format can be different from the data format of the first data field 15 or the second data field 20, but need not be. If more than two data fields in the transmission frame 1 is provided, of different formats are stored in at least two of the data fields data, wherein the position of these data fields in the transmission frame 1 is irrelevant.

p0018By broken lines in <figref idrefs="f0001">figure 2</figref> It is indicated that the first data field 15 may include a first data field specific identifier 45 additionally featuring the construction and / or the content of the first data field 15th Accordingly, the second data field 20 may include a second data field 50-specific identifier which characterizes the structure and / or the content of the second data field 20th Accordingly, the third data field 25 may comprise a third data field-specific identifier 55 which identifies the structure and / or the content of the third data field 25 and the fourth data field 30 may comprise a fourth data-field-specific identifier 75, the structure and / or the content of the fourth data field 30 features.

p0019The first identifier 35 may include information on the number of data fields 15, 20, 25, 30 in the short message. 5 Additionally or alternatively, the first identifier 35 comprise information about the data formats of the data stored in the data fields 15, 20, 25, 30 data. Additionally or alternatively, may include information on the size of the data fields 15, 20, 25, 30 to be included in the first identifier 35th The second identifier 40 may then include information about the data type of data stored in the data fields 15, 20, 25, 30 data. Thus, the second identifier 40, for example, contain information on whether stored in a data field is audio data or image data.

p0020It can now be provided that the operator 70 at the request of the first party, the first data field 15 with the first identifier 35 and the second identifier 40 to the first participant received 60 60 so that the first subscriber 60 because of the first in the identifier 35 and the second identifier may consider 40 transmitted information on the structure and / or content of the short message 5, which data fields of the short message 5 it can reproduce download due to its functionality from the network operator 70 and / or. In addition, the first participant 60, a decision can be made, which should be ever downloaded from the network operator 70 of readable data fields of the short message 5, if not all readable data fields of the short message 5 at the first subscriber 60 of interest and transmission capacity is to be saved. If after the request of the first subscriber 60 the entire first data field 15 is to be transferred with the first identifier 35 and the second identifier 40 to the first subscriber 60, so it should be ensured as possible that the information stored in the first data field 15 data in all be subscribers of the telecommunications network 10 readable data format. This is especially given if the information stored in the first data field 15 data along with the data in the first identifier 35 and in the second identifier 40 are in a text format, for example, the SMS format (Short Message Service) in accordance with the GSM (Global system for Mobile Communications) serving, as it is readable by the trained according to the GSM standard, subscribers or mobile devices of this telecommunication network in a space formed according to the requirements of the GSM system telecommunication network. Here, the first data field 15 may correspond to the previously already prescribed for the SMS short message service according to the GSM standard data field and be limited in size to 160 7-bit ASCII text characters (ascii). The other data fields 20, 25, 30 need not be limited in their size.

p0021Another data format for the first data field 15, which by all participants of the telecommunication network 10 is an alternative to text format also readable is the binary coding of references to items in such tables, containing known data formats and all participants of the telecommunication network 10 are known.

p0022At least a portion of the stored in the first data field 15 data, for example data on the first identifier 35 and / or the data of the second identifier 40, then consist of binary coded values ​​representing the indexes of table entries. In the tables are known data types and / or data formats, such as audio and / or video formats associated with these indices.

p0023The data area-specific identifications 45, 50, 55, 75 may include information about the data formats in the respective associated data field 15, 20, 25, 30 and / or about the size of the associated data field 15, 20, 25, 30 and / or about the data type include in each data field 15, 20, 25, 30th If it is agreed that in the first data field 15 present the data according to the GSM SMS text format and this data field is limited, for example, to 160 7-bit ASCII text characters, then the first data-specific identifier 45 can also be omitted. It can be provided that in each data field 15, 20, 25, 30 only data from a single data format are stored. However, it can also be provided that at least one of the data fields data from multiple data formats are stored, particularly in the second data field 20 and / or optionally in one or more other data fields 25, 30. It can also be provided, of course, that the short message 5 more than the four in<figref idrefs="f0001">figure 2</figref> Data fields shown includes.

p0024It can also be provided that the release of the network operator 70 of the structure and / or content of the short message 5 created the first site 60 after its request by the network operator 70 by evaluating the data field specific identifiers 45, 50, 55, 75 and then the first to the participants will be sent 60 so that the first identifier 35 and the second identifier 40 are not required in this case, and also the first data field 15 does not have to be sent to the first participant 60th The message generated in this way on the structure and / or content of the short message 5 may also be sent in a format accessible by all nodes of the telecommunication network 10 data format to the first subscriber 60, however, including in particular again with the GSM SMS text format using a data field for example, 160 7-bit ASCII text characters can be provided.

p0025Based on <figref idrefs="f0001">figure 3</figref> will now be described a specific example of a transmission frame 1 for a short message. 5 The short message 5 is designed as a multimedia short message. Like numerals in<figref idrefs="f0001">figure 3</figref> featuring the same elements as in <figref idrefs="f0001">figure 2</figref>, Here, according to<figref idrefs="f0001">figure 3</figref> the first data field 15, the second data field 20 and the third data field 25 is provided in the transmission frame. 1 Fielded data identifiers in the individual data fields 15, 20, 25 are not provided. The first data field 15 includes this text data in ASCII text format, the second data field 20 includes audio data, for example, according to the WAV format (Wave) and the third data field 25 includes image data, for example, according to the GIF format (Graphic Interchange Format). The first data field 15 with the text data is text reformatted according to the GSM-SMS-short message service. By a dashed line between the first identifier and the second identifier 35 is 40 in<figref idrefs="f0001">figure 3</figref> indicates that the first identifier and the second identifier 35 40 may be combined into a common identifier. Such a common identifier 35, 40 indicates the number of the data fields 15, 20, 25, and the content as well as the size of the second data field 20, and the third data field 25th So could the common identifier 35, 40 look like this: "Multipart / 2 / Audio / 7654 / Image / 12345"

p0026This common identifier 35, 40 states that it is a short message from a plurality of data fields according to the tag "Multipart". The number "2" indicates that in addition to the always present first data field 15 with the text data and the length of 160 7-bit ASCII text characters two data fields 20, 25 in the transmission frame 1 of the short message 5 are present. As the first data type in the common identifier 35, 40 it is "Audio" called so that seen from the common identifier 35, 40 that it is audio data in the data stored in the second data field 20th is Second, the data type "Image" in the common identifier 35, called 40, so that it is apparent from the common identifier 35, 40, that it is image data in the data stored in the third data field 25th Subsequent to the type of data is in the common identifier 35, 40 in each case indicated the size of the associated data field 20, 25, so that from the common identifier 35, 40 a length of a transferred in the second data field 20 audio file byte with the audio data from 7654 and one in third data field shows 25 transmitted image file containing the image data of 12345 bytes. For the first data field 15 information is not required in the common identifier 35, 40, because it is always is text data in the example described, the compatible with the GSM SMS text format and in their number to 160 7-bit ASCII text characters are limited. There may additionally be provided that the common identifier 35, 40 also indicates the data format for the data in the second data field 20, and the third data field 25th WAV format could be specified for the audio data in the second data field 20 then in the common identifier 35, 40 as a data format. For the image data in the third data field 25 the GIF format may be specified in the common identifier 35, 40 as a data format. It is also possible that the information "Audio" and "Image" of the above common identifier 35, 40 at the same time the content and the format of the data stored in the corresponding data fields 20, 25 describe, in which case, for example, assumed that audio data always in a predetermined format, also ever present, for example the WAV format and image data in a predetermined format, for example, the GIF format in the corresponding data field of the transmission frame. 1

p0027As described, it is also possible to encode the data type and / or the data format to all subscribers of the telecommunications network 10 known tables, for example by means of a binary code. In the first table of data types, for example, the data type "Text Data" the number "1", the data type "audio" the number "2", the data type "image data" of the number "3" and the data type "video data" the number "4 be "assigned, the numbers can be binary-coded accordingly. In a second table for data formats of the data type "audio", for example, the data format "WAV" the number "1", the data format "G.723" the number "2", the data format "G.728" the number "3" the data format "MPEG Audio" (Motion Picture Expert Group) of the digit "4", and the data format "AMR" (Adaptive Multi rate) of item be allocated to "5", these numbers may again be binary-coded accordingly. In a third table for data formats of the data type "image data", for example, the data format "GIF" the number "1", the data format "JPEG" (Joint Picture Expert Group) of the numeral "2" and the data format "BMP" (bitmap) of "3" be assigned paragraph, these numbers may again be binary-coded accordingly.

p0028The common identifier 35, 40 could look as follows: 2/2/1/3/1

p0029This common identifier 35, 40 indicates the same as that described above in text format. Here is the first digit "2" of the common Ken arrangement 35, 40 for the number of addition to the first data field 15 existing data fields in the transmission frame 1 of the short message 5. The second digit "2" of the common identifier 35, 40 points in the first table for types of data to the data type "audio" and thus indicates that audio data 20 are stored in the second data field. The third digit "1" of the common identifier 35, 40 points in the second table of data formats of the data type "audio" on the "WAV" data and states that present the data stored in the second data field 20 data in "WAV" data , The fourth digit "3" of the common identifier 35, 40 points in the first table of data types on the data type "image data" and thus indicates that 25 image data are stored in the third data field. The fifth digit "1" of the common identifier 35, 40 points in the third table for data formats of the data type "image data" in the "GIF" data and states that present the data stored in the third data field 25 data in the "GIF" data ,

p0030Because of the 60 transmitted to the first subscriber identifier common 35, 40 can be decided at this if a download of the second data field 20 and / or the third data field 25 from the network operator 70 is at all useful or wanted. If the first subscriber 60 is not audio capable, ie no processing or reproduction ability has for audio data, then downloading the audio data from the second data field 20 from the network operator 70 does not make sense. If the first subscriber 60 is not capable of forming, ie no processing or reproduction of image data at the first subscriber 60 is possible, so a download image data from the third data field 25 from the network operator 70 is also not useful.

p0031To select the downloaded from the network operator 70 data fields of the transmission frame 1 of the short message 5 may be provided to indicate the common identifier 35, 40 on a display device of the first user 60th

p0032The short message 5 may also include a transmission frame 1 exactly two data fields 15, 20, which as described text data is present in the first data field 15 with the common identifier 35, 40 and multiple data types or media are summarized in the second data field 20th However, it can also be provided that N is distributed in the short message data to be transmitted 5 styles or media on N or N + 1 data fields in the transmission frame 1 of the short message. 5 The first station 60 may individually all data fields of the short message 5 or download together by the network operator 70th

p0033The first subscriber 60 can also already an evaluation of the transmitted common identifier 35, carried out 40 so that their display on the display device of the first user 60 already indicates which data fields of the short message 5 at all can be downloaded from the network operator 70 due to the functionality of the first subscriber 60th

p0034The second subscriber 65 generates an instant message 5 in the described transmission frame 1. The generation of a transmission frame 1 at the second subscriber 65 can simply by joining together the individual data fields 15, 20, 25, 30, if appropriate with the addition of each of the data field specific identifiers 45, 50, 55, 75 take place. The network operator 70 again receives and stores short messages in 5 described transmission frame 1. Subject to the first subscriber 60 functionality may be provided, the transmission frame 1 completely download from the network operator 70 and to transmit to the first party 60th In this case, the first subscriber 60 receives the short message 5 in the described transmission frame 1, stores them if necessary, and / or are optically and / or acoustically. The first subscriber 60 receives at least a single data field of the transmission frame 1, it stores if necessary, and / or there is optically and / or acoustically. An evaluation of received data fields 15, 20, 25, 30 from the network operator 70 and the first station 60 can for example be due to the data field specific identifiers 45, 50, 55, 75, if they are transferred to the associated data fields 15, 20, 25, 30 or due to the optionally transmitted first identifier 35 and / or second identifier 40th

p0035The transmission frame 1 of the invention is not limited to use in a wireless telecommunication network, but can also come in a wired telecommunications network 10 to apply, in which case the subscriber 60, 65 and the network operators are 70 wired. It may also be envisaged that one of the two participants 60, 65 65 is connected via a wired telecommunications network 10 and the other of the two participants 60, via a wireless telecommunications network 10 to the network operator 70 in conjunction, so that the transmission frame 1 for both the transmission is capable of short message 5 in the wired as well as wireless telecommunications network in the tenth
