Description

The The invention relates to a method and a communication device to implement a dialing operation, starting from a first communication terminal and directed to a second communication terminal.

at A connection of telephone calls have different Procedures formed how and at what time digits one Call number to be evaluated. With a similar telephone becomes usual every dialed digit transmitted from the phone after their entry without delay to the relevant exchange. The Exchange usually evaluates with analog switching technology Immediately remove each incoming digit and build as soon as the evaluation this results in a connection to a remote exchange on. When entering a phone number, for example, "03022730431", where the digits one after the other are transmitted to the central office Evaluation of the first digit "0" that it is a long-distance call is. Along with an evaluation of the following two digits "30" can be obtained through the central office already after evaluation of only three digits a line to be set up to an exchange in Berlin. The others Numbers "22730431" are successively handed over to a Berlin exchange, this exchange Now successively evaluates the remaining digits and the connection to the associated Trunk - in this example, a head of the German Bundestag - durchschaltet. The above-mentioned method in which each accruing digit is evaluated immediately will, is usually characterized as an on-going choice, characterized by that connection step by step is constructed from different connecting sections.

at The use of digital technology in the exchanges can numbers entered on a telephone continue to be sent to one associated Notified to the exchange but it usually has the possibility, to collect the incoming digits and then evaluate them together. In such a collection of dialing digits now results for the exchange the difficulty, the actual End of the dialing digit entry to recognize, because only after fully received destination number the evaluation of the destination number can be done.

be based the exchanges on voice-over-IP technology, so will according to protocol specifications and according to the opposite circuit significantly different routing method is expected that the full Dialing numbers together in a data packet at an exchange or a Switching station functionally corresponding switching device arrive. While specific voice-over-ip devices to these specifications prepared, especially when coupled with traditional ones analog or digital telephones via an appropriate gateway the problem that with the gateway, the dialing digits may be one by one arrive, but this gateway the dialing numbers only protocol compliant together in one for that forwarded field of a data packet. Thus results for the task of the gateway to cache the dialing digits and to collect and after complete Input of the dialing digit sequence in a common data packet.

Is solved this usually by waiting the expiration of a timer after entering a respective one Digit, where the time until the expiration of the timer for slow Number input must be sufficiently dimensioned, since too early tripped switching attempt leads to incorrect connections or rejection of the connection request, what again to more limited Acceptance or frustrations in entering the numbers Operators of a telephone. By the use of this too for slow operation sufficiently sized timer can do it to significant delays in the call establishment of over Voice-over-IP links lead mediated connections.

It The object of the invention is as fast as possible Processing of dialed digits for one largely delay-free Allow connection establishment.

Is solved this object by a method for implementing a dialing operation according to claim 1, and a communication device according to claim 13.

advantageous embodiments and further developments of the invention are specified in the dependent claims.

In the method according to the invention for converting a dialing operation initiated by a first communication terminal and directed to a second communication terminal by means of a communication device - in particular a conversion device - notes of one of the communication devices of the first communication terminal sequentially supplied and consisting of at least two Known to be processed Kenntonfolge be detected and / or recognized. For a respective detected tone a Kenntoninformation descriptive of the tone is detected. In addition, will an identification tone information is formed in such a way that the detected identification information is appended to a sequence of identification information which is assigned to the identification code preceding the respective identification tone. Furthermore, a comparison of Kenntonketten information with at least one reference phone number information, wherein in accordance with the Kenntonketten information with the reference phone number information of the dialing process is triggered to the second communication terminal.

The In this case, the method is advantageous in that the dialing process after the arrival of a last note to the second communication terminal without further delays can be discontinued. In contrast, becomes common in known methods waits for a timer expiration until a dialing is initiated.

Preferably a key is a signal that has a dial digit to address a Destination terminal represents and for a connection is used. In addition, a key can but also represent a signal by means of which between a terminal and a Switching station features are signaled or user actions on the terminal the exchange according to a pre-defined protocol.

Preferably the communication device makes a transition between two different ones Networks with different protocols ready. In particular, in one between the first communication terminal and the communication device provided first protocol dialing numbers transmitted sequentially and individually be while in a second protocol between the communication device and the second communication terminal device transmitted knowledge block by block can be. In this case, it may be necessary that through the communication terminal collected all the sequentially arriving notes and as one common entity. This may be for Formation of the unity of knowledge Be important, the end of dial digit sequence to recognize. This is fast and delay-free by the method according to the invention possible. Thus lets after receipt of the last Kennons the Kenntonfolge delay Establish connection to the second communication terminal. In this way, by the method of acceptance in a increased the first communication terminal user because there are no unnecessary waiting times when establishing a connection. This can continue especially in the case of solving emergency calls especially be important, since in this case a delayed switching through a Connection request undesirable is to get the user as soon as possible with an emergency center connect to.

Under the first and the second communication terminal are in particular voice terminals such as telephones or as so-called soft clients called telephony applications a workstation, alternatively terminals or application programs for Multimedia or data connections under these terms can be.

The Communication device is in particular a transition device between Lines with different protocols or between networks, referring to different from their structure or protocols used. About this can For example, the connection to the first communication terminal via a wired analog telephone method - for example PCM-coded (PCM: Pulse Code Modulation) - to be performed while the connection to the second communication terminal via a packet-switched network, for example based on an Internet Protocol (IP) can be. Known communication protocols based on the Internet Protocol, For example, methods according to SIP (Session Initiation Protocol) - defined through the IETF (Internet Engineering Task Force) - or after H.323, the latter protocol being adopted by ITU-T (International Telecommunication Union, Telecommunication Standardization Sector) was specified.

Known in the context of the invention preferably protocol-compliant implementations of dialing digits that have been entered via a user interface of the first communication terminal. In addition to the dialing digits 1 to 9, special characters such as the "#" character can also be understood as an identification tone.These notes are transmitted in chronological succession with different or uniform distances to each other to the communication device according to the inventive method A characteristic tone information describing an identification tone may in particular be a representation as characters "1", "2", "3", ..., in any desired form, for example according to ASCII or Unicode coding (ASCII: American Standard Code for Information Interchange) - can be coded. According to the invention, a sequence of identification information is created according to the arrival order of the notes, the summary of the identification sequence relating to a common character string being referred to as identification tone chain information. An identification chain information "54321" is thus an illustration of a call number received by the communication device as a result of having known for the dialed digits 5-4-3-2-1.

The Method is particularly advantageous, if preferably for frequently selected communication partner a recording of the corresponding telephone number information as the at least one reference telephone number information takes place. The least a reference phone number information can, for example, as List of reference telephone number information to be constructed. But also every other representation of the at least one reference telephone number information is conceivable, preferably with the fastest possible access to the individual reference telephone number information values are reached should.

In an alternative advantageous embodiment, each on and outgoing connection are analyzed and the corresponding telephone number information, which is in the signaling, in which at least one Reference numbers information be recorded. It should be noted that the process in particular is advantageous if the inventive comparison of Kenntonketten information with the entries the at least one reference telephone number information runs much faster than an otherwise scheduled timer would expire at the end of the dial tone chain to recognize.

Preferably can in an advantageous embodiment of the invention with detected agreement the identification tone information establishing a connection with the stored reference telephone number information immediately triggered be by the Kenntonketten information or the hit in the list of reference telephone number information as destination address information for the Established connection to the second communication terminal becomes.

In a further advantageous embodiment of the method can upon arrival of the notes each successive, the identification chain information to each newly arrived Kennton be extended. Upon arrival of a Dialing sequence 5-4-3-2-1 can thus after receipt of the fourth dialing digit 2 to the on this At the time of the existing identification tone information "543", the identification information "2" is appended so that the identification chain information "5432" results The last identification information thus results as identification tone information the entire chosen one Number. This is listed in the Example the telephone number information "54321." Now applies over a certain period of time no further tone and results in the comparison no match between the tag information and one of the reference phone number information, so the dialing process can be triggered after a timer expires. About that In addition, this can be chosen Number information recorded as additional reference phone number information, so that further connection attempts to the same phone number afterwards to a coincidence in Comparison between the tag information and the reference phone number information to lead.

In a further advantageous embodiment of the method can be considered be that only not yet included phone number information as a new entry in the at least one reference phone number information be included, so no duplicate entries in this List of reference telephone number information can be found. On this way, it can be ensured that an investigation regarding the Comparison as possible done quickly can be.

In a further advantageous embodiment of the method can in addition the analysis of the notes about that also directed to the first communication terminal and thus be evaluated in the opposite direction signaling. The signaling, for example, as a packet-oriented data packets Network can arrive be analyzed such that it extracts the sender or source call information contained therein be added to the list of reference phone number information to become. Thus can be achieved in a quick manner that all usually associated with the first communication terminal Communication partner in the reference telephone number information list by means of their numbers are recorded.

Furthermore may prove to be advantageous in the at least one reference phone number information only valid and save as destination numbers to use numbers. The validity can be guaranteed, for example, by storing the telephone number information as a reference phone number information only takes place as soon as a connection is established positive way could be completed. This is for example by lifting the called remote site given.

The validity of the telephone numbers can also be guaranteed, for example, in an alternative development of the method such that a coupling of the communication device to a server takes place, which can send a query to an electronic telephone book. Such an electronic directory can have a list of valid destination numbers. This can For example, for a company to be a company phone book, which includes all employees of the company and their contact options. Alternatively, this may also be an available on the Internet electronic directory, which can be queried for example via HTTP messages (Hypertext Transfer Protocol) or by means of LDAP (Lightweight Directory Access Protocol).

Further advantageous embodiments and further developments of the method according to the invention are described below explained in more detail with reference to a drawing.

there each show a schematic representation of the

1 a block diagram of a communication system comprising components for carrying out the method according to the invention;

2 a block diagram of an alternative communication system, in which an access to an electronic telephone book is provided;

3 a flowchart of method steps of an embodiment of a communication device according to the invention.

In 1 schematically a block diagram of a communication system is indicated, in which a first communication terminal EG1 is coupled via a connecting line AL to a gateway device GW. The first communication device EG1 is an analog telephone, for example, and the connection line AL is a line for transmitting analog signals from the first communication terminal EG1 to a first interface of the gateway device GW. The gateway device GW represents the inventive communication device or the inventive conversion device and is also coupled to an Internet Protocol network IPN by means of a second interface. In the exemplary embodiment, it is assumed that the gateway device GW a packet-oriented communication protocol, z. B. SIP, and in this way communicates with packet-oriented devices in the Internet Protocol network IPN. While any internet protocol based transmission protocols are conceivable, in the following only one embodiment variant based on SIP will be explained in more detail.

Im - in the Figurine stylized as a cloud - Internet Protocol Network IPN is, for example, a so-called gatekeeper GK as a connection-controlling component of the SIP network intended. About that addition is a SIP-compliant second communication terminal EG2 - preferably an IP phone or a communication application on a workstation - as well arranged in the Internet Protocol Network IPN.

integral Components of the gateway device GW are moreover a SIP user agent SUA, the for communication with components of the Internet Protocol network IPN is provided, as well as a choice of evaluation WA for analysis from above the connection line AL incoming signals and a message evaluation device MA. After all the gateway device GW also comprises a telephone number memory RUNOSP, in turn, a phone number list RUNOL for storage the invention at least a reference telephone number information includes.

in the Frame of the embodiment Let it be assumed that the first communication terminal EG1 and the second communication terminal EG2 each in a Hibernation are, as a triggering step of the method according to the invention the first communication terminal EG1 by lifting it telephone receiver leaves hibernation.

in the The following will now be done by a user by pressing dialpad or by selecting one stored number from a phone number memory a sequence of knowing entered at the first communication terminal EG1. The one given dialing digits be as knowledgeable about the Connecting line AL to the gateway device GW individually and in succession, in particular, while maintaining pauses between the known.

at The arrival of the first can already be done by the gateway device GW a protocol-compliant data packet according to SIP are generated that for one to be performed Connection setup can be used. This connection setup but can only be triggered will all be needed as soon as possible dialing digits arrived there as per the SIP protocol it is obligatory that all dialing numbers are the for one Addressing a destination number are necessary, together in an address field of a data packet.

It is now checked by the gateway device GW for each incoming dialing digit, if a destination number has already been fully received, so that the possibly already generated data packet structure can be filled and sent to the Internet Protocol network IPN. An evaluation as to whether the end of a dialing digit sequence has already been reached is carried out using several procedures: For example, it is examined whether a previously defined time span has elapsed after an incoming identification tone is exceeded, so that this is interpreted as an indication that the dialing digit sequence is completed; In addition, it can be examined whether a predefined, particularly excellent identification tone - for example an identification tone specified by the "#" character - arrives - which explicitly defines the end of the dialing digit sequence.

Additionally done according to the invention by means of Wahlauswertungseinrichtung WA an analysis of the current and the already arrived notes. Each incoming tone is included in the gateway device GW Arrival by appropriate wiring of the first interface recognized and converted into a descriptive Kenntoninformation this, which then subsequently by means of data processing technology Functions can be processed further. For an identification sequence 7-6-5-4-3-2-1 Thus, the first characteristic is a signal representing the number 7, by Detection in the gateway device GW is converted into the associated identification information "7". After detection of the first identification information is a query the number memory RUNOSP, whether for this key or for this Identification information An entry in the telephone number list RUNOL exists is. In the present example, for the number "7" there is no entry in the number list RUNOL exists, so that the election evaluation device WA reported back is that the comparison has delivered a negative test result. In The gateway device GW thus becomes either a timer or timer sequence Waited or there is an arrival of another dialing number on the first interface. This is in the present example by the Key to the dialing digit 6, since according to the example the dialing digit sequence 7-6-5-4-3-2-1 in succession will arrive.

When second identification tone is now at the gateway device GW the Kennton 6, which in turn is converted into a corresponding identification information "6". For this Signal tone and the already preceding identification tone with the identification information "7" will now be an identification information formed such that both values in succession as Kenntonketten information be further processed. This would be In the present example, the identification tone chain "76" is now triggered checked is whether in the phone number memory RUNOSP an entry for this Identification tone information is present. This is in the present example not the case, so again a negative test result to the electoral evaluation device WA returned becomes. Again, the timer expiration or the arrival of a another dialing digit maintained.

To a certain time delay - due to Breaks between the incoming Knowledge - is now another key by the first communication terminal EG1 to the gateway device Transfer GW. This characteristic is according to the embodiment a representation the dialing digit 5, so that the gateway device GW the associated identification information "5" from the incoming Can determine the characteristic tone. Once again, an identification information formed from the just received Kennton and the already previous knowledge is composed so that the identification chain information "765" results Formation of the identification chain information can on the one hand the chain information can be reassembled in each pass or it can in one pass to the tag chain information of the previous pass resorted be so that only the last digit to the previous Kenntonketten information attached must become. For the Resulting tag information "765" will now be repeated by the election evaluation WA a comparison of this identification tone information triggered with the stored reference telephone number information. It a query is again made to the telephone number memory RUNOSP - for example by means of a query job Q from the election evaluation device WA and the call number memory RUNOSP -, in turn, an investigation the number list RUNOL. Again results in the present embodiment no agreement of the comparison. As a result, once again in this run Disagreement reported to the election evaluation WA.

The mentioned method steps are now processed dial number for dialing digit repeatedly, so that in the following the input of the notes 4-3-2 is skipped, since analogue to the steps just described.

Meets now after the processing of the knowledge 2 the one of the dialing digit 1 defining characteristic tone at the gateway device GW, so is again formed to this key 1 Kenntoninformation "1" and formed a Identification chain information about all Kennton information generated. The keychain information is in this case the chain "7654321" for this Label information becomes again a comparison with the list of the reference telephone number information - the telephone number list RUNOL - aimed at. A corresponding query job Q is from the election evaluation device WA and sent to the phone number memory RUNOSP.

Assuming that there is an entry for the reference telephone number information "7654321" in the telephone number list RUNOL, the comparison of the given telephone code information "7654321" with the stored reference telephone number information provides a positive check fergebnis. This positive test result is transmitted to the election evaluation device WA, from which it can draw the conclusion that the last dialing digit has arrived and can now be carried out in the following immediately without further delay, a connection to the entered phone number. The identification tone information or the matching reference number information is then entered by the gateway device GW in a preferably pre-established data packet for a connection. Alternatively, the data packet can only be generated at this time. Via the SIP user agent SUA likewise contained in the gateway device GW, a connection to the telephone number "7654321" is then initiated into the packet-oriented network IPN.

Of the Establishment of a connection in the Internet Protocol network IPN takes place based on known protocols and known mechanisms. For example A message is sent to a gatekeeper by the SIP user agent SUA GK about transmits a data path DP1, to determine the Internet address of the addressed destination numbers "7654321" the gatekeeper GK the destination Internet address to the SIP user agent SUA has returned This can be a connection to the desired target device - the second Communication terminal EG2 - build up via the data path DP2. Thus, the connection between the first communication terminal EG1 and the second communication terminal EG2 signaled through the gateway device GW. As a result of this will be about this both communication terminals EG1 and EG2, ringing and ringing tones issued.

The Process therefore offers the particular advantage that after arrival the last dialing digit immediately a connection can be initiated.

If now alternatively a dial digit sequence arrives, which has not yet been stored in the telephone number list RUNOL, so the process in this case can not speed up the connection setup cause because a timer expires after the most recently received one Notification or arrival of a unique end identifier has to wait, but can a data representation this incoming dialing digit sequence used to also be included in the phone number list RUNOL to be able to. This has the advantage that thus in a further connection attempt to the same number then an entry in the number list RUNOL will be found, so in this case, a faster connection possible will be.

The Component that performs the investigation, whether already an entry in the telephone number list RUNOL is present, and beyond that Recording a new entry in the phone number list RUNOL initiated, is in the present embodiment referred to as message evaluation device MA. The message evaluator MA is between the election evaluator WA and the SIP user agent SUA arranged. The message evaluator MA is on this Way in the signaling path between the connecting line AL and the Internet Protocol network IPN arranged or has access to a message traffic between the connection line AL and the Internet Protocol Network IPN. The message evaluator MA now offers the possibility in case of mismatch the comparison and at the completion of the dialing digit sequence simultaneously with initiating the connection setup by means of an insert job S the phone number list RUNOL to expand an entry namely to the entry of the current dialing digit sequence. Preferably This recording of a new entry can be made only if A connection setup could be successfully performed to the validity to verify the phone number. Thus it would be ensured that no erroneous or invalid Posts be included in the telephone number list RUNOL. Furthermore, can the message evaluator MA also from the Internet Protocol network Analyze IPN incoming messages and source number information included in these messages also in the phone number list RUNOL record, so that after a all usually for a while with the first communication terminal EG1 frequently in Contacting communication partners in the telephone number list RUNOL are included.

In 2 is analogous to 1 in turn, a communication system shown, comprising a first communication terminal EG1, a gateway device GW and a second communication terminal EG2. Furthermore, a gatekeeper GK is again shown in an Internet Protocol network IPN. The gateway device GW again comprises a selection evaluation device WA, a message evaluation device MA and a SIP user agent SUA. A telephone number memory RUNOSP, however, is not included in the gateway device GW. The function of the telephone number memory RUNOSP, however, is taken over by the combination of a telephone book server TS with an electronic telephone book ET, the telephone book server TS can manage the corresponding electronic telephone book ET, configure, manage and query. The electronic telephone book server TS is arranged in the Internet Protocol network IPN and can be via Internet-based protocols, such as LDAP (Lightweight Directory Access Protocol). A query is in the 2 again indicated by a query Q.

The electronic telephone book ET is, for example, a database that includes all the contact addresses of persons of a company. In addition, the electronic telephone book ET may also be an internet telephone directory listing all registered users of a particular region or country. When establishing a connection from the first communication terminal EG1 to the second communication terminal EG2, a query can therefore be sent to the telephone book server TS for checking the dialing digits or the associated acknowledgments, so that analogous to the representation in FIG 1 a query can be made for the validity of a key chain information. The successive queries digit by digit takes place analogously to the explained procedure in 1 , So that each incoming Kennton a Kenntonketten information of the previously accumulated knowledge is formed and the Kenntonketten information is compared with each entries of the electronic telephone book ET.

In addition, a combination of 1 and 2 be useful - not shown - in which on the one hand a phone number memory RUNOSP and on the other hand a telephone book server TS is provided. In this case, a comparison can be made with respect to the telephone number list RUNOL and, in addition, a comparison with the entries in the electronic telephone book ET. This has the advantage that on the one hand registered users are included in the electronic telephone book ET but still be able to contact individual users who are not registered in the electronic telephone book ET in a fast way by comparing them with the telephone number list RUNOL.

The in the 1 and 2 presented methods are particularly advantageous if a database query or a query of the telephone number list RUNOL can be performed much faster than a usually provided timer sequence for detecting an end of a dial digit sequence.

Based 3 is now in a functioning of the gateway device GW descriptive flow chart again the procedure already with reference to the 1 and 2 has been explained. Starting situation of 3 Let be an idle state of the first communication terminal EG1 and also an idle state of the gateway device GW. The latter corresponds to the state 1 in the 3 , If a signaling or a data packet now arrives at one of the inputs - the first or the second interface - of the gateway device GW, the gateway device distinguishes at which input this signaling or the data packet has arrived. This is by the branching number 2 indicated in the figure.

Lies Now a signal at the analog input of the connection line AL, so the left branch of the flowchart is traversed. Is against it a data packet at the input of the Internet Protocol network IPN, so will go through the right branch of the flowchart.

If the signal now arrives at the analogue input of the connecting cable AL, then it is assumed that this is the first dialing digit of a dialing digit chain. This will be in the step 3 indicated by the setting of a loop variable X to the value 1, wherein such a step may not be performed explicitly in an implementation of the gateway device GW. For clarification of the method steps with reference to the flow chart, however, the use of a loop variable seems reasonable. In step 4 the currently creating characteristic tone is recognized as an incoming dialing digit and recorded as associated identification information. In the following step 5 For this identification information, a query of the telephone number memory with respect to the dialed numbers accumulated up to this point in time takes place. In the branch 6 an evaluation is made for the identity code sequence to match the comparison values of the telephone number list RUNOL.

If there is a match, a transition is made to the step 10 if not, a transition to branching 7 , In step 10 if a flag designated as HITER is set to "yes", then a transition is made to the step 11 ,

If the identification chain has been identified as not matching, a transition to the query takes place, as already mentioned 7 , This waits for the arrival of a note of the dial digit sequence or on the time-out of a timer, depending on which event occurs before. If a next characteristic tone arrives, then in the step 8th the run counter X increments and processing again at step 4 so that the newly entered characteristic tone is detected and processed as identification information. Conversely, in the query 7 that no further tone arrives and thus a time-out of the timer occurs, so is the step 9 the flag TREFFER is set to "no", followed by a transition to the execution step 11 ,

In step 11 Now a connection or a call is initiated. This is followed by a transition to the query 12 after successful call setup It checks whether the previous match check found a match. This is determined by the value of the flag TREFFER. If no hit was found, then in the step 13 creates an additional entry in the telephone number list RUNOL. Thereupon, a transition to the connection state takes place 30 , Returns the query in the query step 12 If a match has been found, then a transition to the connection state is made directly 30 completed.

Not shown in the figure, in addition, a review of incoming notes in terms of of predefined, particularly distinguished acquaintances, the define an end of an identification sequence. For example could an identification sequence can be terminated by selecting the "#" key or the "*" key. Upon arrival Such Kennons the Kenntonfolge is completed. When checking against the Reference phone number information can be the Kenntonketten information which is associated with the identification Identification information # or * included. Alternatively, the identification tone information only all previously received notes include, without the Signal tone information # or * is recorded. A review of Kenntonketten information after the arrival of the "#" - or "*" - needs knowledge but not mandatory become. It can be triggered directly without delay a dialing, since such a tone uniquely determines the end of the dial digit sequence.

Starting from the query 2 is now treated in another branch of the diagram what happens when an incoming data packet arrives at the entrance to the Internet Protocol network IPN. This is shown in the flow chart on the right. There is first a transition to the process step 20 in which a sender or source address is extracted from the incoming traffic. This extracted address will be on it in step 21 added to the phone number list RUNOL. This completes the administrative steps and it can be done in step 22 the call to the analogue input is output.

Furthermore, there is a transition to the state 30 representing a connection state of the gateway device, wherein between step 22 and step 30 If necessary, further steps necessary for switching through a connection can be carried out, but these need not necessarily be displayed to explain the idea according to the invention.

Next the illustrated by the drawing shown Embodiments, Many other embodiments of the invention are conceivable. For example can stored as reference telephone number information Information at intervals on validity checked be so invalid become entries deleted can be. In this case, in one embodiment, each entry of the at least one Referenced call number information assigned a validity expiration date become.

One about the Connection line AL coupled first communication terminal EG1 does not have to be mandatory for an analogous protocol may be provided. The invention can be about that out for every one Insert a scenario in which signals or Packets arrive individually at another output of the communication device should be passed on together and summarized, so that a grouping of incoming data and possibly an intermediate buffering from already arrived but not further processed information is required.
