Method for the transmission of email messages

State of the art

The invention relates to a method for transmitting electronic mail messages according to the category of Main claim from.

The publications "Technical realization of the Short Message Service (SMS); Point-to-Point (PP) "GSM 03:40 V7.1.0 (1998-11) and 3 G 23.040 V3.2.0 (1999-10) is already a method for transmitting Internet emails under Using the SMS short message service (Short Message Service) known, with a with a SMS short message in Telecommunications network an Internet e-mail and address and Identification data for transmission of internet email are transmitted on the Internet. The default in accordance with the Publications referred to provides for the possibility, via the short message service SMS Internet to send e-mails and to receive. For this purpose must while sending a so-called Signaling entry PID (Protocol Identifier) ​​in a Header information of the SMS short message accordingly be adjusted; order to the short message pointed transmitted Internet e-mail. The data part of the SMS short message starts here with the destination address for the Internet e-mail. When receiving Internet e-mail through SMS Short Message Service is the destination address of a Network unit replaced with the source address of the sender been. The separation between Internet e-mail destination or Source address and the actual Internet email in the SMS short message is simply a space.

Optional supports the standard pursuant to those Publications specifying multiple destination addresses must be separated by commas, and data fields "Subject" to indicate the title of the Internet e-mail and "Real Name" to specify the actual name of the Sender. As separator between these data fields it is provided, the data field "Subject" in brackets to set or two prefix characters as For example, to indicate "##". The data field "Real Name "is a special character, such as" # " in.

ADVANTAGES OF THE INVENTION

The inventive method for transmitting electronic mail messages having the features of Main claim has the advantage that with the Instant message a first header information with a Signaling is transmitted at least one data field, which comprise the address and / or identification data that transmit a second header information with the short message is that the presence of the first header information indicating, within and in that the at least one data field a data portion of the short message outside any Header information are transmitted. In this manner, a first service provider of the first communication network in Function of an analysis of the second header information the short message to a second service provider of second communications network forward, then based the first header information further evaluation of Short message to extract the electronic Mail message from the short message and for forwarding the electronic mail message over the second may make communication network. It is therefore not necessary for the first service provider of the first Communication network at the same time of the service provider second communication network.

By means of the first header information can also point to a special form of addressing the electronic Mail message be noted that the in the extraction electronic mail message by the second Service providers can be considered. The shape of the Addressing thus be flexibly choose. requirement is merely that the second service provider each specified form of addressing the electronic Post message, and thus knows for extraction and Evaluate forwarding the electronic mail message can.

are of the measures listed in the dependent claims Advantageous further developments and improvements of the Main claim specified method possible.

It is particularly advantageous that the at least one Data field with an operator for the transmission of first header information is identified. In this way can be multiple data fields with little effort clearly differ.

A further advantage is that the keyword is transmitted coded. In this way, the Impairment of the data capacity of the short message by the transfer of one or more keywords on a Minimum.

It is particularly advantageous that the first is transmitted header information, a marking field, the shape of the address and / or identification data indicates. In this way, an error-free evaluation of the at least one data field in the second service provider ensured so that the contained in the short message electronic mail message to the person or the right Recipients are transmitted in the second communication network can.

A further advantage is that at least one transmitted third header information with the short message is that as part of the electronic mail message to a linked by transmission of multiple short messages entire electronic mail message features. On Thus, it is particularly in a predetermined Dataset limited short messages, yet a predetermined amount of data the border electronic mail message by linking several to send short messages in the first communication network, wherein the electronic mail messages via the at least a third header information with each other concatenated short message to the second service provider put together an entire electronic mail message and at least one specified in a data field of the second Destination can be sent.

Embodiments of the invention are shown in the drawing represented and in more detail in the following description explained. Show it<b>Fig.</b> 1 is a transmission path of a transmitter to a receiver, <b>Fig.</b> 2 a first example for a schematic structure of a short message with integrated electronic mail message and <b>Fig.</b> 3 a second example of a schematic construction of a Short message with an integrated electronic mail message.

Description of Embodiments

In <b>Fig.</b> 1 features <b>125</b> a transmitter which a Short message with an integrated electronic mail message to a first service provider <b>140</b> via a first communication network <b>100</b> transfers. The first service provider<b>140</b> forwards the short message via the first communication network <b>100</b> to a second service provider <b>150</b> a second communication network <b>200</b> continue. The second service provider <b>150</b> extracted from the short message the electronic mail message and directs it through the second communication network <b>200</b> to a receiver <b>175</b> continue.

The first service provider <b>140</b> and the second service provider <b>150</b> are embodied as two separate units. they can, however, integrated into a common unit be.

In the <b>Fig.</b> 2 features <b>5</b> an instant message. The short message <b>5</b> is from the transmitter <b>125</b> of the first communications network <b>100</b> generates, as described above the first service provider <b>140</b> of the first communications network <b>100</b> to the second service provider <b>150</b> the second communication network <b>200</b> using the first communication network <b>100</b> transfer. For the Transmitting such short messages <b>5</b> is this the first communication network <b>100</b> a so-called short message service furnished. Such short message service exists For example, in a designed as mobile network first communication network <b>100</b>, This can be at a such mobile network, for example a mobile radio network according to the GSM standard (Global System for Mobile Communications) or to the UMTS standard (Universal Mobile Telecommunications System) act. When GSM Mobile Network is the so-called SMS-short message service (Short Message Service) is specified, the of the sending SMS short messages between a sender and a Receiver provides, the SMS Short messages to text messages a maximum Text length is limited by currently 160 characters. Should larger text messages are transmitted, so has the SMS short message service, the possibility of chaining a plurality of SMS messages, that is to be transmitted Text message is distributed to several SMS Kurznächrichten.

The in <b>Fig.</b> 2 short message shown <b>5</b> includes basically a second header information <b>12</b> and a data part <b>50</b>, The second header information<b>12</b> includes Signaling messages and a first destination address for the to send short message <b>5</b> or a source address for the for receiving short message <b>5</b>, The first destination address denotes the first service provider <b>140</b> of the short message <b>5</b> the first communication network <b>100</b> and the Source address identifies the sender <b>125</b> the short message <b>5</b> the first communication network <b>100</b>, The data part<b>50</b> includes the actually message to be transmitted and thus the so-called payload. When will SMS short message service while the source address or the first destination in accordance with the Publications "Technical realization of the Short Message Service (SMS); Point-to-Point (PP) "GSM 03:40 V7.1.0 (1998-11) and "Technical realization of the Short Message Service (SMS); Point-to-Point (PP) "3G 23.040 V3.2.0 (1999-10) on a so-called MSISDN number (Mobile Subscriber Integrated Services Digital Network) identified. In the transmission of the short message<b>5</b> in the first communication network <b>100</b> addresses a in <b>Fig.</b> 1 not shown network unit of the first communications network <b>100</b> the first service provider <b>140</b> of the short message <b>5</b> with reference to the first destination and replaced these by the source address of the sender <b>125</b>, By default this includes the second header information <b>12</b> exactly one Source address or just a first destination address.

The short message <b>5</b> comprises according to the <b>Fig.</b> 2 a first header <b>11</b>That the data part <b>50</b> the short message <b>5</b> is arranged. The first header information<b>11</b> is the SMS Short message service as a user data header information or "UserDataHeader" means.

The presence of the first header information <b>11</b> Data Division <b>50</b> is a corresponding entry in signaling the second header information <b>12</b> displayed. When SMS Short message service are different types of "User Data Header "in accordance with the above-mentioned publications" Technical Realisation of the Short Message Service (SMS); Point-to- Point (PP) "specified. They are doing by a Marking field <b>15</b> in the first header information <b>11</b> according to the <b>Fig.</b> 2 distinguished from each other, said <b>Fig.</b> 2 shows the construction of the first header information <b>11</b> detailed represents.

In the data part <b>50</b> the short message <b>5</b> can now take a electronic mail message <b>1</b> be transmitted. Of the Signaling entry in the second header information <b>12</b> thereby indicates in addition that with the short message <b>5</b> a Such electronic mail message is transmitted. This is the first service provider <b>140</b> after evaluation of the second header information <b>12</b> recognized. therefore he directs the Short message to the second service provider <b>150</b> as described, since this is the service provider of the the second communication network <b>200</b>That for transmission Such electronic mail messages is provided, functions and the transmission of the electronic post message <b>1</b> in the second communication network <b>200</b> thus can cause. The first service provider<b>140</b> must therefore not the same service provider of the second communications network <b>200</b> let alone participants be the same. The short message<b>5</b> with the electronic post message <b>1</b> So is the second as described service provider <b>150</b> the second communication network <b>200</b> via the first communication network <b>100</b> transmitted, the second service provider <b>150</b> Also participants of the second communications network <b>200</b> is. The electronic post message <b>1</b> is now the second service provider <b>150</b> at the recipient <b>175</b> the second communication network <b>200</b> be transmitted. These may be in the second communication network <b>200</b> for example to the Internet act, the electronic mail message <b>1</b> then represents, for example, an Internet e-mail.

With the data part <b>50</b> are now several data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> transmitted outside of any header information Address and identification data for the transmission of electronic mail message <b>1</b> in the second communication network <b>200</b> include. After evaluation of this address and Identification data in the second service provider <b>150</b> can the electronic mail message <b>1</b> to the receiver <b>175</b> of the second communication network <b>200</b> to get redirected. To However, should the second service provider <b>150</b> the short message <b>5</b> be notified, how the data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> are organized or whether such data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> in the data part <b>50</b> are present at all. This is done using the identification data field <b>15</b> in the first header <b>11</b>, There is a so-called identifier to the way in which the address and identification data in the data part <b>50</b> present and also thus signaling the Presence of data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> ever. For example, specify the identifier that the data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> Data Division <b>50</b> one from the Publication "Standard for the Format of ARPA Internet Text Messages "IETF, RFC 822 addressing known and Identification of the electronic mail message <b>1</b> include. According to the <b>Fig.</b> 2 are an example of the data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> for an RFC 822-addressing in accordance with that Posted represented.

The first header information <b>11</b> is a first length data field <b>40</b> preceded by the length UDHL (UserDataHeader Length) of the first header information <b>11</b> indicates. the first Length data field <b>40</b> then follows the already described Marking field <b>15</b> with the identifier IEI (Information Element Identifier), which indicates in this case, that the data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> an RFC 822 addressing represent. The identification data field<b>15</b> is one of second length data field <b>45</b> followed that the length IEIDL (Information element identifier data length) of a third Length data field <b>46</b> indicates. The third length data field<b>46</b> indicates the length of data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> Data Division <b>50</b> at. The data fields<b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> even then the data part <b>50</b> outside any header information such arranged described. The data fields<b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> be it in the data section <b>50</b> the electronic post message <b>1</b> preferably preceded immediately transfer. By means of the length specified in the third Length data field <b>46</b> then the data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> clearly of the electronic mail message <b>1</b> in the data part <b>50</b> be separated. This separation may additionally or alternatively by using a for this purpose supports predefined special separation sign , provided this separation mark is otherwise not in the data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> and the electronic mail message <b>1</b> used. For this purpose is in<b>Fig.</b> 2, a region <b>60</b> after the first header information <b>11</b> and the electronic mail message <b>1</b> Data Division <b>50</b> shown, in which the data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> are arranged. The data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> are key distinguished from each other, wherein each data field <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> a keyword is assigned. These key words are the second service provider <b>150</b> known. As a result the predetermined keywords a unique Identification of the data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> given is, can depending on the desired application in its type and number various data fields in the data part <b>50</b> be arranged. According to the <b>Fig.</b> 2, four data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> provided. It could however also be more or less. A first data field <b>20</b> is exemplified as formed Zieladreßdatenfeld that a second destination address the electronic mail message <b>1</b> and thus comprises the receiver <b>175</b> the electronic mail message <b>1</b> in the second communication network <b>200</b> features. The Zieladreßdatenfeld<b>20</b> Therefore for forwarding the electronic post message <b>1</b> in the second communication network <b>200</b> indispensable, however, it may, due to the associated Key word at any point in the field <b>60</b> of the data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> be arranged, as it on the basis of Keyword from the second service provider <b>150</b> clearly is identified. The same applies to all other Data fields. A second data field<b>25</b> in the area <b>60</b> of the data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> may as be Quelladreßdatenfeld formed and the source address the electronic mail message <b>1</b> include, so that when receiver <b>175</b> the electronic mail message <b>1</b> in the second communication network <b>200</b> the transmitter <b>125</b> the electronic post message <b>1</b> is identifiable.

A third data field <b>30</b> in the area <b>60</b> the data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> may be formed as the label data field, one name or title of the electronic post message <b>1</b> includes.

A fourth data field <b>35</b> in the area <b>60</b> the data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> may be formed as name data field the sender's name <b>125</b> the electronic mail message <b>1</b> includes, but is not in the form of the source address, but for example in the form of a pre- and a surname, so as a personal name.

The assignment of the data fields to the key words, for example, look like this: The Zieladreßdatenfeld is associated with the key word "To." the Quelladreßdatenfeld <b>25</b> is the key word "From" assigned. The label data field<b>30</b> is this assigned keyword "Subject". The name field<b>35</b> should not be used in this example.

The following is an example of the construction of the data fields <b>20</b>. <b>25</b>. <b>30</b> in the area <b>60</b> described. there first, the second header information <b>12</b> the Signaling entry TP UDHI (Transfer Protocol-User Data Header Identification) indicating whether the first header <b>11</b> and thus an electronic post message <b>1</b> in the short message <b>5</b> present. Is this the case, TP-UDHI is set to 1, otherwise TP UDHI set to 0. The first header information<b>11</b> can then for example, be structured as follows: In the first Length data field <b>40</b> is the length of the first UDHL header <b>11</b> set to 3 in hexadecimal. in the Marking field <b>15</b> is the identifier IEI 20 set and indicated by these in hexadecimal Value the presence of data fields <b>20</b>. <b>25</b>. <b>30</b> in the Area <b>60</b> and described RFC 822 addressing under a corresponding mapping table. In the second Length data field <b>45</b> the length IEIDL to one in Hexadecimal set and thus indicates that the length the third length data field <b>46</b> a sign and therefore a is Byte and therefore 8 bits, so that the third Length data field <b>46</b> maximum of 255 characters for the length of the data fields <b>20</b>. <b>25</b>. <b>30</b> may specify. The length of the data fields <b>20</b>. <b>25</b>. <b>30</b> is then in this example, in the third length data field <b>46</b> to the value of 37 in the Hexadecimal set. In the event that the length of data fields <b>20</b>. <b>25</b>. <b>30</b> is greater than 255, at least 2 Bytes for the length specified in the third length data field <b>46</b> required. Correspondingly, the entry in the second Length data field <b>45</b> Two or more to set. alternative can on the third length data field <b>46</b> be waived if between the region <b>60</b> with the data fields <b>20</b>. <b>25</b>. <b>30</b> and the electronic mail message <b>1</b> a separator agreed. This can according to the RFC 822 Addressing, for example, a blank line. Is this third length data field <b>46</b> not required, then the second length data field <b>45</b> corresponding to zero.

In Zieladreßdatenfeld <b>20</b> referenced the keyword "To" with the following string of 27 characters as a Web page Address formed second destination address for this Example constructed as Internet e-mail electronic post message <b>1</b>:To = Gunnar.Schmidt@Bosch.com

In Quelladreßdatenfeld <b>25</b> referenced the keyword "From" a well-trained as an Internet address Source address to identify the sender <b>125</b> of the electronic mail message <b>1</b>Wherein in Quelladreßdatenfeld <b>25</b> following string of 23 characters is formed:From = +49xxxyyyyy@zzz.de

The source address is obviously as a formed Phone comprehensive Internet e-mail address and not personalized. A personalized Identification of the sender <b>125</b> the electronic post message <b>1</b> is using the name of the data field <b>35</b> as described possible, but not, in this example provided.

In Name field <b>30</b> in this example is a String of 12 characters is provided, in which the Keyword "Subject" the designation of the electronic post message <b>1</b> referenced as follows:Subject = Test

Other data fields are not in this example in the field <b>60</b> provided. Overall, in this example, include the three data fields used <b>20</b>. <b>25</b>. <b>30</b> sixty two Mark, the binary for example, each having seven bits be coded so that for encoding 55 bytes required are. It corresponds to the number<b>55</b> in the Decimal system of numbers <b>37</b> in the hexadecimal system and thus the the third length data field <b>46</b> provided value.

Since the data fields <b>20</b>. <b>25</b>. <b>30</b> with the address and Identification data in the actual message of the short message <b>5</b> are, for example, a 7 bit Coding of characters according to the publication "alphabet and language-specific information ", GSM or 3GPP 03:38 23,038 applicable.

In the example described, the individual data fields are <b>20</b>. <b>25</b>. <b>30</b> not only on the keywords clearly in but also separated from each other. The means that the content of each data field <b>20</b>. <b>25</b>. <b>30</b> must not contain keywords. This requirement is However meaningless if each data field <b>20</b>. <b>25</b>. <b>30</b> With a separator is completed and agreed is that the respective data field characterizing provided keyword at the beginning of this data field must be such that the first separation mark for a subsequent keyword newly incipient field features and all subsequent keywords to next separator rather than marking a new data field are interpreted. For the Zieladreßdatenfeld <b>20</b> then could the string starting be formed by the above example as follows:To = Gunnar.Schmidt@Bosch.com &lt;CR &lt;.

Exemplary was here as a separator &lt;CR &lt;, ie Carriage return or "Carriage Return" is selected. This extended the string to a total of 28 characters.

As another alternative to the described example, the Characters are binary coded in eight bits. This increased the possible character sets, the possible number of Sign of the electronic mail message <b>1</b> is characterized However, further reduced.

In the example described remain for the actual electronic mail message <b>1</b> Data Division <b>50</b> of the short message <b>5</b> less than 100 characters left if from a short message <b>5</b> by SMS default and the current Limit of 160 characters per text message in this SMS Standard is assumed.

It is therefore advantageous that the keywords described RFC 822 addressing, for example, with seven Bit to encode binary to save characters. This can via a predetermined lookup table, which in transmitter <b>125</b> and the second service provider <b>150</b> is known and, for example, looks like this:

<tgroup cols="2"><tbody><entry align="left">keyword</entry><entry align="left">Binary Code (7 bits)</entry><row><entry align="left">to:</entry><entry align="left">&lt;0000000 &lt;</entry></row><row><entry align="left">from:</entry><entry align="left">&lt;0000001 &lt;</entry></row><row><entry align="left">Cc:</entry><entry align="left">&lt;0000010 &lt;</entry></row><row><entry align="left">Bcc:</entry><entry align="left">&lt;0000011 &lt;</entry></row><row><entry align="left">Subject:</entry><entry align="left">&lt;0000100 &lt;</entry></row><row><entry align="left">...</entry><entry align="left">...</entry></row></tbody></tgroup>

In addition to the described keywords "To", "From" "Subject" contains the table than other keywords: "Cc" and "Bcc". Also is indicated in the table that other than as described further keywords may be provided. For each area in<b>60</b> used Keyword is in the manner described Data field in the area <b>60</b> provided. The keywords "Cc" and "Bcc" featuring more destination addresses to which the electronic mail message <b>1</b> in the second communication network <b>200</b> in addition to under the keyword "To" specified second destination address is to be transferred.

Alternatively to the described example, the Keywords are binary coded with eight bits.

According to the example described above would be by Coding key then in the field <b>60</b> following yield:

In the first length data field <b>40</b> would UDHL remains at 3 are set in hexadecimal. in the Marking field <b>15</b> IEI would remain at 20 in Hexadecimal system are set to the RFC 822 addressing to reference still. In the second length data field<b>45</b> would IEIDL remains at one in the hexadecimal system are set. The length of the data fields<b>20</b>. <b>25</b>. <b>30</b> in the Area <b>60</b> is now in the third length data field <b>46</b> 2b in Hexadecimal set. By encoding the Key word "To" in the table with the characters &lt;0000000 &lt;would the string in Zieladreßdatenfeld <b>20</b> now 25 characters long and look like this:&lt;0000000 &lt;Gunnar.Schmidt@Bosch.com

By encoding the keyword "From" with the Mark &lt;0000001 &lt;according to the table would Quelladreßdatenfeld <b>25</b> now a string of 19 Characters long and look like this:&lt;0000001 &lt;+41xxxyyyyy@zzz.de

By encoding the key word "Subject" by the Mark &lt;0000100 &lt;according to the table would Identification data field <b>30</b> now a string of five Characters long and look like this:&lt;0000100 &lt;Test

Thus arise for the data fields used <b>20</b>. <b>25</b>. <b>30</b> now 49 characters in binary encoding with 7 each Bit 43 bytes would require, with the number 43 in Decimal system of number 2b in the hexadecimal system and thus the the third length data field <b>46</b> similar to that specified value.

In this way, characters can be saved, which the electronic mail message <b>1</b> to provide can.

The value 3 for UDHL indicates that first for header <b>11</b> Data Division <b>50</b>, So for the first Length data field <b>40</b>, The second length data field <b>45</b>, the third length data field <b>46</b> and the identification data field <b>15</b> a maximum of 3 bytes, ie 24 binary digits available to stand.

It can now be provided that the first next to the header <b>11</b> at least a third header information <b>13</b> with the short message <b>5</b> is transmitted, the electronic mail message <b>1</b> as part of a means of Transmission of multiple short messages concatenated whole electronic mail message <b>1</b> features. The chronological order between the first header information <b>11</b> and third header <b>13</b> can also be interchanged. Only the second header information <b>12</b> should at the beginning of the short message <b>5</b> to stand. Even more information can head the short message <b>5</b> be added in any order with the first header message <b>11</b> and optionally third head message <b>13</b>Wherein the second header information <b>12</b> always at the beginning of the short message <b>5</b> must stand.

The third header information <b>13</b> is optionally provided. <b>Fig.</b> 3 shows starting after the example <b>Fig.</b> 2 a short message <b>5</b> with integrated third header information <b>13</b>, The same reference numerals denote like elements as in <b>Fig.</b> 2. The structure of the short message in accordance <b>Fig.</b> 3 corresponds to the according to the example <b>Fig.</b> 2 -described construction, with the difference that the third header <b>13</b> in the example of <b>Fig.</b> 3 now additionally in the short message <b>5</b> between the first header information <b>11</b> and the area <b>60</b> is arranged. The third header <b>13</b> differs from the first header <b>11</b> definitely by the identifier in Marking field <b>15</b>, Using this identifier , the second service provider <b>150</b> the first header <b>11</b> of the third header information <b>13</b> differ.

The third header information <b>13</b> shall also submit a code contain the entire electronic mail message features. In the second service provider<b>150</b> then all received by short message electronic Post messages to each other the entire electronic Post message concatenated, the latter by the identifier entire electronic mail message are referenced and in this form, electronic as a linked whole Mail message to the according to the second destination address in Destination address field <b>20</b> addressed recipients <b>175</b> in the second communication network <b>200</b> transfer. Here, the third header <b>13</b> also contain a sequence number, indicating at which point the electronic post message <b>1</b> the respective short message <b>5</b> in the concatenated entire electronic mail message is, so that several electronic highlighted in this manner Mail messages in the second service provider <b>150</b> in the correct order can be chained together. It may also be provided for the labeling the entire electronic mail message and the Marking the sequence number of the respective electronic mail message each own Header information in the short message <b>5</b> provide and a corresponding identifier in Marking field <b>15</b> to distinguish from each other.

By evaluating the data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> is the second service provider <b>150</b> able from the short message <b>5</b> the electronic mail message <b>1</b> from the data part <b>50</b> extract, as the first header information <b>11</b> and optionally further header information of the data part <b>50</b>Such as the third header information <b>13</b> and finally the area <b>60</b> the user data in data part <b>50</b> are always preceded and each have at least one length of the data field, from its length and in the case of the first header information <b>11</b> and the length the range <b>60</b> can be determined. It can also be provided that only in the first header information <b>11</b> by length data fields lengths of all the data part <b>50</b> existing header information <b>11</b>. <b>13</b> and data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> be made so that length corresponding data fields in the further Header information of the data part <b>50</b> and the area <b>60</b> not required are. For this purpose it may be provided that the first length data field <b>40</b> the first header information <b>11</b> the Total length of all header information <b>11</b>. <b>13</b> of the data portion <b>50</b> indicates. Out of the area<b>60</b> with the data fields <b>20</b>. <b>25</b>. <b>30</b>. <b>35</b> then also the and for addressing Identification of the electronic mail message <b>1</b> obtained the information needed for the Transfer the extracted electronic mail message <b>1</b> in the second communication network <b>200</b> to there addressed receiver <b>175</b> and the identification of the transmitter <b>125</b> at the receiver <b>175</b> required are. For the pure transmission the electronic mail message <b>1</b> to the receiver <b>175</b> of the second communication network <b>200</b> is in the range <b>60</b> of the usable data fields only Zieladreßdatenfeld <b>20</b> indispensable. The Quelladreßdatenfeld<b>25</b> and the Name field <b>35</b> serve only to identify the transmitter <b>125</b> and the name data field <b>30</b> is merely titling and thus the identification of electronic mail message <b>1</b> itself. The third header <b>13</b>Whose presence also through a corresponding entry in the second signaling header <b>12</b> is referenced, the second service provider <b>150</b> detect whether the electronic post message <b>1</b> Part of a whole to be concatenated electronic mail message heard. Based on a further in the <b>Fig.</b> 2 header information is not shown, the Presence also by a corresponding Signaling entry in the second header information <b>12</b> is referenced, the second service provider <b>150</b> recognize at which point the whole to be concatenated electronic mail message, the electronic mail message <b>1</b> the short message <b>5</b> is, if this information is not already in the third header information <b>13</b> is included.

Corresponding to the detected position of the electronic post message <b>1</b> in total to be concatenated electronic mail message can then the second service provider <b>150</b> the electronic mail message <b>1</b> of the short message <b>5</b> at the corresponding location to the concatenated entire electronic mail message signature.

The inventive method is not limited to the SMS Short message service limited in GSM mobile network, but applicable for any short message services, in which transmit electronic mail messages with text messages be, wherein the electronic mail message also does not have to be an Internet e-mail.
