Description

  • The present invention relates to an addressing method for bidirectional sending of electronic messages between one Communication application with a sender identification OID and a dialog-capable terminal with a recipient identifier MSISDN over a Transmission system, the terminal for bidirectional communication with Devices with IDs in the OADC format is set up to Identifier format is compatible with MSISDN.
  • Under a message is an electronic broadcast with a content (body), to understand a sender identification and a recipient identification, wherein for the present invention, messages are considered in which Sender ID and recipient ID are separated from the body. The body can be any content. Examples of this are text without and with Formatting, images, films, sound files etc. A prominent example is the in z. B. GSM networks possible sending short text messages (SMS). The further development of communication technology and with it accompanying definition of new communication standards with extended Functionality (UMTS, etc.) will enable messages with SMS in future extended content (e.g. future MMS, EMS, XMS standards etc.).
  • In the network of terminal devices, identifiers are in the general OADC format communicate. The terminal uses an identifier in a special format MSISDN, which can also be switched in the network of end devices. The format the identifier MSISDN can correspond to the format OADC, the format OASDC can also be a standardized short form or long form of the format, Be MSISDN. To be exemplary for the MSISDN of the terminal device Cell phone number in the format +49 171 1234 567. Exemplary for that Format OADC is the format of the "short IDs" often used today named (e.g. 72872 = short ID of the applicant), under the terminals, in particular exchanges (e.g. SMS message centers), at least can be reached within the network of a mobile operator.
  • In the future it will be possible to use the MSISDN instead of the usual phone number in the above-mentioned. Format z. B. an IP address can also be used, as is the case with future cellular standards such as UMTS is discussed.
  • The end device is set up to exchange messages with others Terminal devices whose identification has the more general format OADC, but in particular can have the special format MSISDN.
  • The terminal can e.g. B a cell phone, pager or PDA (personal digital assistant). For the devices mentioned, the identifier would be, for example their respective phone number. In particular, the terminal can be on a Communication standards such as the GSM standard and for which Exchange of text messages (SMS) with other devices on the based on the same communication standard.
  • The communication application is for bidirectional communication with Set up terminals with the identifier MSISDN, d. H. it is for shipping and set up to receive messages. The Communication application at least temporarily an identifier OID that the Communication application clearly identifies. The Communication application can be, for example, a software application for sending emails (Email client). Other examples are internet based services for Sending messages such as B. SMS or emails. The However, the communication application can also be any end device. The identifier OID of a Email clients would be e.g. B. the email address used for sending the Identifier OID of an internet-based service would be e.g. B. a "session identifier" an open internet session.
  • The transmission system can e.g. B. be a physical network, which can work wirelessly or wired, especially that Network of a GSM or UMTS network operator, also and especially in Internet connection.
  • The present invention relates to the case that the terminals are not for sending messages directly to communication applications an identifier of the format OID is set up, d. H. are in this sense the mentions MSISDN and OID incompatible. The end devices are rather for sending messages to end devices with IDs in OADC format set up.
  • An example of this problem is the sending of an email to a GSM Mobile phone illustrated. Many mobile network operators offer a service that does it enables short emails to be sent to a cell phone, where they are sent as SMS be received. For this, the email is sent to a router of the Network operator addressed, e.g. B. at the email address "Mobile number @ 4Mobilfunknetzbetreiber.de ". The router routes the body of the email as an SMS to the specified mobile number, where i. a. the email address of the Sender is added to the body of the SMS. A reply from the cell phone to the Email address of the sender via reply function is i. a. not easily possible because the reply function sends an identifier to the router's OADC addressed SMS would be generated. So far, it has therefore been necessary for the Users of the cell phone of the received SMS the email address of the sender removes and manually into the body of the reply SMS he wrote inserts that then to an email router of its mobile network operator is sent. The email router is equipped with the ability to Extract email address from the body of the SMS and the SMS as email to the forward the extracted email address, d. H. the procedure sets one technically complex email router with recognition intelligence (a "parser") ahead.
  • A similar situation arises when sending SMS to a cell phone via an internet-based service ("SendSMS ™"). For this, a Communication application on the Internet a session at a "SendSMS ™" server established. In this session there will be a text message created and stating the recipient's mobile number to the server transmitted. The server routes the text message as to the specified one SMS directed to mobile phone number in the network of the mobile network operator of the selected cell phones. The sender's address contains that of the cell phone received SMS then the identifier OADC of the SendSMS ™ server. In addition, the text message i. a. another information about the provider of the Internet-based service attached. An identifier that identifies the sender identified and under which a response from the cell phone would be possible not planned so far. It is therefore not possible to use the phone as Reply a message to the still open session of the Send communication application.
  • With the current state of the art, the usual GSM Two-way communication with a cell phone Communication application either not at all or only with increased effort for the Mobile phone users possible and continues to use intelligent routers Mobile operator ahead.
  • The object of the present invention is therefore to provide an addressing method for the transmission of messages between communication applications and end devices of the type mentioned at the beginning, which the bidirectional transmission of messages enabled without technical Make changes to the end devices necessary.
  • This task is solved by an addressing procedure in which the Communication application with the sender identification OIDi, the one to the Terminal sent with the identifier MSISDNj directed message from Transmission system a dynamic response identifier OADCi is assigned. This assignment is made for the terminal MSISDNj. If another message is sent via the transmission system from the same Communication application OIDi or another Communication application OIDm addressed to another terminal MSISDNk, so the Sender identification OIDi or OIDm is also a dynamic one Response identifier OADCi or OADCm assigned, this assignment for the Terminal MSISDNk is valid. The response identifier OADCm can be the same the reply identifier OADCi or different from it.
  • The OIDi-OADCi assignment valid for the MSISDNj terminal is for a determined finite period, the lifetime τ valid. The Reply identifier OADCi becomes a finite pool of n identifiers OADC1 to OADCn taken, each terminal MSISDN such Pool is assigned.
  • The response identifier OADCi is the message to be transmitted as Sender identification attached, so that the MSISDNj Message transmitted the body of the communication device OIDi generated message, MSISDNj as recipient identifier and the Reply identifier includes OADCi as sender identifier.
  • A new message can now be sent as a reply by means of the terminal are written, which may be implemented using a "reply" Function "is automatically addressed to the response identifier OADCi. The message also contains new content (body) and the MSISDNj of the answering device as sender identification. From the contained This is determined by OADCi and the identifier MSISDNj of the answering terminal Transmission system the identifier of the communication application OIDi, on whose message is followed by the reply. The transmission system generates a new message addressed to the OIDi communication application the body of the reply, the identifier OIDi as the new recipient identifier and the identifier MSISDNj of the answering terminal as Sender ID. This message is sent to the OIDi communication application.
  • Particular advantages of the method according to the invention result if the number n of the response identifiers OADC is chosen to be less than 1000, preferably less than 100, in particular less than 10, since the response identifiers are a limited resource in the networks of the mobile radio operators. The number of response identifiers n required for a sequence of the method according to the invention below a maximum error rate in the return addressing is in an interplay with:
    • a) the number of messages per time that are addressed by different communication applications OIDi, j to a terminal MSISDNj, and
    • b) the lifetime τ of the assignment OIDi-OADCi.
  • If the number of messages per time increases, the number of messages remains the same Lifetime more response identifiers needed to the OADC Keep error rate constant. If the lifetime τ is reduced Assignments OIDi-OADCi, the number n of the reply identifiers can be reduced the error rate for the same number of messages per time to keep constant.
  • The selection of a reply identifier OADCi, that of a sender identifier OIDi can be assigned in various ways to implement.
  • In a simple first implementation, the response identifier OADCi by a random process from the entire pool OADC1 to OADCn selected. If the pool size is sufficient (e.g. n> 10) and smaller Number of messages per time by different ones Communication applications OIDi, j addressed to a terminal MSISDNj, results in a Relatively low error rate caused by assignment of only one Reply identifier OADCi to several different sender identifiers OIDi, j, k is caused. The terminal answers to the Reply identifier OADCi, there is no clear assignment to one Sender identification OIDi more. In this case, depending on the implementation No reply or to a (possibly) wrong sender identification delivered.
  • In a preferred second implementation, the risk of Incorrect addressing of the reply is excluded by the fact that when a Message from the Communication application OIDi in the transmission system is checked whether for the terminal MSISDNj already has a currently valid assignment of the sender identification OIDi for a reply identifier OADCi.
  • If there is a valid assignment OIDi-OADCi, it can already existing assignment used for the new message to be transmitted are, whereby preferably the lifetime τi is set outgoing from the time of receipt of the later message from OIDi to MSISDNj.
  • If there is no valid OIDi-OADCi assignment, a free, i.e. H. to the Time of receipt of the message, response identifier not assigned OADCi selected from the pool OADC1 to OADCn. In other words, which is current at the time the message is received by MSISDNj assigned response identifiers OADC are from the pool of OADC excluded that are available for the terminal MSISDNj.
  • From the rest of the pool, for example, a randomly selected a new reply identifier OADCi and be assigned to the sender ID OIDi. This is how this works long error-free until OADC arrives at the time a message is received the terminal MSISDNj all available for the terminal MSISDNj standing reply identifiers are currently assigned.
  • In general, incorrect addressing can be minimized if the Time of receipt of a message directed to the terminal MSISDNj from the communication application OIDi in the transmission system Virtual assignments currently valid for the terminal MSISDNj Sender IDs OADCj, j ∈ [1, n], from the pool available for OADCi be excluded.
  • Another source for possible incorrect addressing when delivering a Answer by the transmission system lies in the finite Lifetime τ of the OIDi-OACDi assignments. Should that for the Communication application OIDi provided reply only after the expiry of the When the service life τ arrive at the transmission system, their treatment depends on the further implementation of the addressing procedure in Transmission system.
  • In a simple first implementation, one is assigned Response identifier OADCi immediately after the end of its service life τ free, d. H. it will be available to the pool Reply IDs for the terminal MSISDNj fed back and can will be awarded again immediately. So the danger is one Incorrect addressing of responses increased significantly. Should the reply identifier OADCi when the communication application OIDi actually arrives directed reply already again another Communication application OIDj would be assigned, so the response would be incorrect Communication application OIDj delivered. This danger can be avoided decrease if the original message of the communication application OIDi and the terminal MSISDNj provide information about the lifetime τ is added. This can happen, for example, that the body the message from the transmission system to the user of the terminal addressed note on the limited lifespan is added, e.g. B in the Form "This. SMS can only be answered within τ". The Information on the limited life τ can also be obtained from Terminal MSISDNj are evaluated themselves, for. B. in the form that after expiration from τ an automated reply using the reply function of Terminal is no longer possible. However, this implies a change in the Terminal implemented functions ahead.
  • In a preferred second implementation, the risk of Incorrect addressing of the reply is further reduced by the fact that a Response identifier OADCi even after its lifetime τi for one further period, the lockout period Ti, from the pool of the available standing response IDs are excluded OADC, d. H. the identifier OADCi stands during the blocking time Ti, which is related to the service life τi not available for assignment to an OID.
  • Further advantages of the method according to the invention result if the Lifetime τ individually to the properties of the sending Communication application OIDi is adapted. Requires that Communication application OIDi, for example, opening a session with a server, such as this when logging in to an IRC server for chatting, an instant Messenger server for sending corresponding messages, a web Mail server for sending emails over the Internet or via "SendSMS ™" server for sending SMS over the Internet is required, the service life τi can be advantageous by the period in which the session of the OIDi communication application is open become. In particular, the transmission system can automatically Send message to the connected MSISDNx devices as soon as the Session of the communication application is ended, which results in that the received messages can no longer be answered.
  • In another advantageous embodiment of the invention The user of the communication application OIDi is a method Option to determine the preferred service life τi offered. The selected option is evaluated by the transmission system and for Determination of the service life τi used. Such an option can be found on particularly simple way in internet-based communication applications to implement. The selectable service life τi is advantageous Transmission system within technically reasonable limits tmin and tmax given, the limits differ individually for each terminal MSISDNj dynamically at the rate of different communication applications OIDx can orient messages addressed to the terminal MSISDNj. If only a few messages are addressed to MSISDNj per time, the maximum lifespan + max are relatively long, so for example a few days. On the other hand, many messages are sent from different communication applications addressed to MSISDNj, so the maximum life tmax relatively short, z. B. 12 to 24 h.
  • As an alternative to the selection option described for the service life τi The transmission system can also be selected by the user be set up that the lifetime τi for each terminal MSISDNj separately according to the number of OIDi, j Automated messages addressed to the MSISDNj terminal per time is chosen and fixed, z. B. analogous to that described above Selection procedure for the maximum life tmax.
  • In a particularly advantageous embodiment of the invention The terminal uses a method for communication today or today future mobile communications standard such as GSM, CDMA or UMTS. Further Advantages arise when the communication application as Internet-based service is designed.
  • Finally, it is possible to switch from the communication application to the Sender identifier OIDi to the terminal with the identifier MSISDNj addressed message to attach a sender ID OIDj to another as the communication application OIDi indicates, to which a possible Reply should be sent.
  • The present method enables bidirectional exchange of Messages between communication applications and end devices also in the case that the proprietary standard of the terminals z. B. in relation to Identifier formats, communication protocols etc. is not compatible with the standard of communication applications. Requirements for the successful transmission of a message is only that the content of the Message from both the end devices and the Communication applications made available to the respective user for use can be, e.g. B. by output on an optical display device (Screen). The method according to the invention thus enables one greater mutual integration of different modern Means of communication as required by many end customers.
  • Further advantages and features of the device according to the invention result itself from the subclaims and the following Embodiments that are explained with reference to the drawing. In this show:

  • Fig. 1 shows a message delivery 6 a communication application 1 with the sender identification OID2 to a terminal 2 to the receiver identifier MSISDN1 via a transmission system 5 in a first implementation of the inventive method. 1 is shown schematically in Fig. Indicated, that the communication applications 1 with the identifiers OID i are located in the network of communications applications. 3 Likewise, the terminals 2 with the identifiers MSISDN are in the network of the terminals 4 . The networks 3 and 4 can be wired or wireless networks or mixed forms thereof. The network of communication applications 3 is connected to the network of terminals 4 via a transmission system 5. The transmission system 5 has suitable interfaces to the network of communication applications 3 and to the network of terminals 4 , which are not shown in FIG. 1, since they are not essential to the invention.
  • The structure of a message 6 , which is sent from a communication application 1 to a terminal 2 , results from FIG. 3. Such a message 6 comprises a body 7 , which represents the content of the message 6 to be transmitted. This body 7 can consist of a simple or formatted text message, as well as any other type of file such as image, sound or film files. Furthermore, part of the message 6 is a recipient container 8 , in which the identifier of the recipient is stored. Finally, part of the message 6 is a sender container 9 , in which the identifier of the sender is stored. In FIG. 3, the sender container 9 contains the sender identification OID2 of the communication application 1 , from which the message 6 is sent. The identifier MSISDN1 of the terminal to which the message 6 is to be transmitted is stored in the recipient container 8 . In addition to the contents shown, body 7 , recipient container 8 and sender container 9 , a message 6 can include further objects, provided the transmission system 5 is set up to transmit corresponding messages 6 . Another object can e.g. For example, it could be the subject line of an email generated by an email application.
  • It can be seen from FIG. 1 that an addressing unit 10 is part of the transmission system 5 . This addressing unit 10 comprises an addressing control 14 , a composer 15 and at least one memory area 11 .
  • The memory area 11 is assigned to a terminal 2 with an identifier MSISDNi. The memory area 11 assigned to a terminal 2 with the identifier MSISDNi can be designed statically or dynamically, that is, it can either always be reserved for a terminal 2 with the identifier MSISDNi belonging to the network of the terminals 4 , or it can only be present if the terminal 2 with the Identifier MSISDNi is dialed into the network of terminals 4 . Finally, the memory area 11 can also be generated dynamically when one or more OID-OADC assignments are to be temporarily stored. In particular, the memory area 11 can be formed by an entry for the identifier MSISDNi in a database.
  • At least one pool 12 is assigned to the memory area 11 , in which the available response identifiers OADCi are stored. Furthermore, the memory area 11 comprises an assignment area 13 , in which the OID-OADC assignments made are stored at least for the duration of their validity.
  • The exact sequence of the first implementation of the method according to the invention will now be described in detail with reference to FIGS. 4 to 10.
  • FIG. 4 shows the processes in the addressing unit 10 upon receipt of a message 6 from a communication application 1 with the sender identification OID 2 , directed to a terminal 2 with the recipient identification MSISDN1. When the message 6 arrives at the addressing unit 10 at the time t2, the composer 15 extracts the recipient identifier MSISDN1 contained in the message 6 and transfers it to the addressing controller 14 . Furthermore, the composer 15 also extracts the sender identification OID of the communication application 1 that sent the message 6 to be transmitted and also transfers this to the addressing controller 14 . The addressing controller 14 selects the memory area 11 assigned to the recipient identifier MSISDN1 and asks in its assignment area 13 whether there is already a currently valid assignment to a reply identifier OADC for the sender identifier OID2. In the example shown, there is no assignment of a reply identifier OADC to the sender identifier OID2 in the assignment area 13 at the time t2. Only currently valid assignments to the sender IDs OID1 and OID5, to which the reply IDs OADC1 and OADCS are assigned, are stored in the assignment area 13 . In addition, the times of receipt of the messages to be transmitted from the communication applications OID1 (here t1) and OID5 (here t5) are also stored in the assignment area 13 in this implementation.
  • In the subsequent step, which can be seen from FIG. 5, the addressing controller 14 selects from the pool 12 in which, in the implementation shown, all those response identifiers OADC are stored which are not currently assigned to a sender identifier OID. In the example shown, the pool 12 comprises a total of 10 response identifiers OADC, namely OADC1 to OADC10. At time t2, the pool includes all of the response identifiers mentioned, with the exception of the identifiers OADC1 and OADC5, which are currently assigned. From this pool 12 , the addressing controller selects the reply identifier OADC whose order number is the smallest, here OADC 2 , and assigns it to the sender identifier OID 2 of the sending communication application 1 . This assignment is stored in the assignment area 13 for the lifetime τ when the message 6 is received by the communication application OID 2 (here t2).
  • In the subsequent method step, which can be seen from FIG. 6, the addressing control 14 takes the assigned return identification OAD C2 valid for the sender identification OID2 from the assignment area 13 and transfers it to the composer 15 .
  • In the final step after all, which is seen in FIG. 7, the composer of the reply identifier OADC2 and the body 7 of the original message 6 generated 15 from the receiver identifier MSISDN1, a new message 6, the network of terminals 4 for transmission to the called terminal 2 is passed with the identifier MSISDN1.
  • From FIGS. 8 to 10, the process flow for the transmission of the reply of the terminal 2 is addressed with the identifier MSISDN1 be seen on the communication application with the identifier 1 OID1. In FIG. 8, a message 6 from the terminal 2 with the identifier MSISDN 1 arrives at the addressing unit 10 at the time t2 + T. The response identifier OADC2 is stored in the recipient container 8 of the message 6 as the recipient address. At the time the message 6 is received by the addressing unit 10 (here t2 + T), the assignment between OID2 and OADC2 made in the method step that can be seen in FIG. 5 still exists in the memory area 11 . Upon receipt of the reply, the composer 15 extracts the sender identification MSISDN1 of the sending terminal 2 contained in the message 6 and the recipient identification OADC2 and transfers this to the addressing controller 14 . The addressing controller 14 queries the memory area 11 , which is assigned to the terminal with the identifier MSISDN1, as to whether there is a valid assignment to the reply identifier OADC2. In the example shown, the assignment OID2-OADC2 is stored in the assignment area 13 .
  • In the next method step, which can be seen from FIG. 9, the addressing controller 14 takes the identifier OID2 assigned to the response identifier OADC2 from the communication application 1 , to which the received message 6 , which was transmitted by the terminal 2 with the identifier MSISDN1, is actually to be addressed and passes this to Composer 15 .
  • In the last process step, which can be seen from FIG. 10, the composer 15 generates a new message 6 from the body 7 , the identifier MSISDN1 of the terminal 2 and the identifier OID2 of the called communication application 1 and transfers it to the network of the communication applications 3 for delivery to the communication application 1 with the identifier OID2.
  • FIGS. 11 and 12 show, finally, a possible implementation of the inventive method, if the reply of the terminal 2 with the identifier MSISDN1, addressed to the communication application 1 with the sender identification OID2 after expiry of the lifetime τ of the assignment OID2-OADC2 in the addressing unit 10 is received. As before, the composer 15 extracts the identifier OADC2 contained in the recipient container 8 from the received message 6 and transfers it, in addition to the sender identifier MSISDN1, to the addressing controller 14 . The addressing control 14 now checks whether there is a currently valid assignment to the identifier OADC2 in the assignment area 13 of the memory area 11 . In the example shown, there is no such assignment anymore, since the assignment OID2-OADC2 made at the time t2 + T when the message is delivered by the communication application 1 with the identifier OID2 to the terminal 2 with the identifier MSISDN 1 no longer exists, since T is greater than the lifetime τ of the assignment made.
  • Fig. 12 shows a possible reaction of the addressing unit 10 on this condition. The addressing control 14 notifies the fact that the reply identifier OADC2 there is no currently valid assignment to an identifier of a communication application OID 1 more, the composer 15. On the basis of this information, the composer 15 creates a new message 6 , addressed to the terminal 2 with the identifier MSISDN 1 and a body 7 , in which it can be seen in any form that is visible to the user of the terminal 2 with the identifier MSISDN1 that the selected one Reply address OADC2 is unknown or the reply takes place after the maximum permissible service life τ has expired and is therefore no longer possible.
  • In summary, a possible implementation of the method according to the invention when delivering a message 6 of a communication application 1 OID1 to a terminal 2 MSISDNj is summarized:
    • 1. The communication application 1 OIDi sends a message 6 addressed to the terminal 2 with the identifier MSISDNj to the transmission system 5 , the message containing a content to be transmitted (body 7), the sender identifier OIDi and the recipient identifier MSISDNj,
    • 2. the transmission system 5 extracts the sender identifier OIDi and the recipient identifier MSISDNj from the message 6 ,
    • 3. The transmission system 5 temporarily assigns the sender identifier OIDi a dynamic response identifier OADCi and stores this assignment in a memory area 11 , which is assigned to the recipient identifier MSISDNi, the assignment of the dynamic reply identifier OADCi to the sender identifier OIDi for a determined finite period τi, the lifetime , remains stored in the memory area 11 and is deleted after the expiry of τi, and
    • 4. The transmission system 5 generates a new message 6 addressed to the terminal 2 MSISDNj consisting of the body 7 and the identifiers OADCi as the sender identifier and MSISDNj as the recipient identifier and transmits these to the terminal 2 with the identifier MSISDNj.
  • A possible implementation of the method according to the invention for transmitting the response of the terminal MSISDNj has the following method steps:
    • 1. The terminal 2 MSISDNi generates a response message 6 , consisting of a new content to be transmitted (body 7), the recipient identifier MSISDNj as the new sender identifier and the reply identifier O-ADCi as the new recipient identifier and transmits this to the transmission system 5 ,
    • 2. the transmission system 5 extracts the new sender ID MSISDNj and the new recipient ID OADCi from the message 6 ,
    • 3. The transmission system 5 calls in the memory area 11 , which is assigned to the terminal MSISDNj, the original sender identification OIDi stored under the response identifier OADCi, and
    • 4. The transmission system 5 generates a new message 6 addressed to the communication application OIDi consisting of the new body 7, the recipient identifier OIDi and the sender identifier MSISDNj and transmits these to the communication application 1 with the identifier OIDi.
