Definitions

  • the present invention relates to a method for realizing a callback system for mobile telecommunication terminals as well as the devices for the telecommunication terminals, e.g. in the form of hardware implemented circuit functions or a program which enables the semi-automatic application and implementation of the method; In addition, it relates to a corresponding telecommunication terminal and server system.
  • callback The method used by callback systems is colloquially called callback and works in principle as follows: A subscriber calls a special call number of the callback system. With the call, the callback system learns the caller number, e.g. by the fixed assignment of the called call number to the call number or by the prior art call number transmission of the telecommunication networks. The calling party now announces to the callback system the call number to be called, e.g. by dialing, then hang up and wait for the callback of the callback system. The callback system dials both numbers, that of the calling and the calling party, via two separate connections and connects them system-internally, so that a call connection between both parties arises when both accept the call.
  • the caller Depending on the tariff classification of a telecommunication network used, the caller incurs costs when calling the callback system, whereby the callback system operators can make this connection cheaper or even free of charge by means of special telephone numbers of the network operators for "shared cost services" or "free call".
  • the callback system selects the respectively most favorably priced telecommunications network or network operator available to it.
  • the call-back system allows the call-back system to offer both calls at a lower cost compared to the costs incurred by the caller by a call to the caller by their network operator Cost advantages are usually not incurred for calls within a telecommunications network of a network operator
  • the domain of the callback systems are connections between the telecommunication networks of different network operators, in particular mobile telecommunication networks, but especially connections to foreign countries.
  • the callback system should be expandable in a special form by suitable services and / or features and integrated into existing callback systems in order to extend them to the functionality of the inventive method.
  • the task solution aims, because of the particularly high cost-saving potential on recalling telecommunications terminals with a flat-rate, but is not limited thereto.
  • This object is achieved by a callback system based on the inventive method.
  • the method describes a decentralized unbalanced callback system for mobile telecommunication terminals, in which the mobile telecommunication terminal to call itself makes the callback, which is why this callback system is a decentralized System is, and thus only one connection, just the callback to the caller, must be established, which is why this callback system is a single-ended system.
  • the callback generally only takes place when the user of the mobile telecommunication terminal accepts the call, which requires a telecommunication terminal-specific action, eg the actuation of a key. Due to the call acceptance action to be performed by the user, this process is also referred to as semi-automatic.
  • the indication of a callback request may e.g. by a suitable list kept in the recalling system with authorized subscribers, or by a suitable signaling used by the calling and recalling system, which is transmitted by means of the infrastructure of the current mobile telecommunication networks or other transmission paths.
  • the callback system rejects when the callback request is recognized when its user performs a telecommunications terminal specific action to accept the incoming call, e.g. by pressing a special key, which is why the system is called semiautomatic, the incoming connection is called off and then the caller is called back.
  • the subscriber requesting the callback does not need an inventive device on his telecommunications terminal, but only the subscriber executing the callback.
  • both the subscriber requesting the callback and the caller executing the callback require the inventive device on their telecommunications terminals.
  • the callback system can be supplemented by a callback system server system, which is looped into a caller and callback connection.

  • the method is based on an appropriate signaling which indicates to the means of the called mobile telecommunication terminal or of the callback system server system a callback instruction, and to one or more lists for the definition, recognition and generation of suitable signaling.
  • the callback system device In an incoming call without callback signaling, the callback system device remains passive on a mobile telecommunication terminal, thus leaving the normal functional flow available for that device, such as setting up a call connection upon actuation of a call pickup key on an incoming call without callback signaling.
  • the callback device In the case of an incoming call with a callback signaling, and after a telecommunication terminal-specific action for the call acceptance by the user and after successful verification of recall-system-specific parameters, the callback device becomes active. It takes over the control of the mobile telecommunication terminal or takes as much influence to automatically reject first the incoming call and then perform a call back to the caller, otherwise the callback device also remains passive.
  • the caller number transmitted with the incoming call is the signaling and thus functions in all telecommunications networks with the feature for transmitting the caller number. Therefore, in order to detect signaling, the call-back system will keep listening to incoming calls and keep a list of call numbers of subscribers authorized to request a call-back called a caller number transmitted in an incoming call If the caller number is found in the subscriber list, this is regarded as verified callback signaling, which callback system is noted internally in a flag or in another suitable manner. described paragraph.

  • the callback system device of a mobile telecommunication terminal is designed for reception, evaluation and optionally now also for the transmission of further signaling.
  • the signaling in the basic form by the caller number is extended for this purpose by two further suitable signaling options: the signaling by telephone number modification by means of a change in the caller number at one or more locations and / or by an extension of the caller number, which also takes place via the connection of the telecommunications network, and a freely definable signaling via a data network connection.
  • a call number modification is made by changing one or more phone numbers of the phone number consisting of the numbers 0 to 9 and the special characters "*" and "#" a phone number, a phone extension is created by adding or adding additional characters of the phone number in or to the phone number. This can be done in principle at any point of the phone number and it can be inserted in principle one or more characters. Practically, however, there are some issues to consider in order for the extension number to be accepted and transmitted in standard telecommunications networks.

  • the current signaling by telephone number modification is currently restricted to ISDN networks and currently not usable for mobile telecommunication terminals.
  • outgoing signaling via data transmission via the Internet is possible and thus constitutes a preferred application.

  • the callback system facility must be able to service and use these interfaces.
  • the purpose of using a mobile telecommunication terminal with the callback system device is primarily the effective use of the callback system server system.
  • the callback system server system can also evaluate the caller number of the callback requesting telecommunication terminal as signaling, the information about the call number of the recalling mobile telecommunication terminal, also referred to below as the destination call number, is still missing in this signaling. This must be redone in a suitable manner, as in conventional callback systems, for example by dialing by DTMF or by voice over the established speech connection. Signaling via data transmission considerably improves this process by transferring all necessary information to the server system via the data connection, which takes place simultaneously or at least practicably before the connection-oriented connection is established.
  • the server system thus knows the caller number and destination number even before the connection is established, optionally the caller's authorization and optionally further relevant information or information. This speeds up the process for the user and makes it transparent. The user no longer needs to know explicitly that he is establishing a connection with a callback system. If the user dials a telephone number, the call-back system device also "listens" here and compares it with the telephone numbers in the subscriber list.
  • the callback system could, for example, proceed as described in the basic form, ie call the destination subscriber directly using the own call number as a signaling, for which the device does not have to become active. In the primary application, the connection to the destination subscriber via a callback system.
  • the call number of the callback system server system is assigned in the substitution list of the destination number, and this in turn the signaling type and all other relevant information is listed in the signaling list, for example, data connection as signaling and as data to be sent the caller number, destination call and an authorization string used for the authorization, eg the IMEI or a manually entered authorization code, optionally also a protocol or the data coding, eg 7-bit ASCH, sequence, encryption, etc.

  • the purpose of the callback system server system is to introduce further services and / or features into a connection between callback requesting and callback subscribers.
  • the connection must be looped via the callback system server system, wherein the callback system server system is connected to one or more telecommunication networks, preferably those according to the ISDN standard or comparable.
  • this initially works in such a way that the call-back requesting subscriber calls the call-back system server system and transmits the callback request itself and the call number of the callback subscriber by means of suitable signaling.
  • the appropriate signaling has already been described and explained with reference to the callback system device for mobile telecommunication terminals.
  • the callback system server system therefore first requires a callback system device with at least one subscriber list and at least one signaling list.
  • the number of lists depends on how the lists are organized for many callback systems. Thus, e.g. the call numbers of all subscribers authorized for a callback request are summarized by the server system in a subscriber list, or a subscriber list is kept for each known and / or registered callback subscriber.

If the signaling of a callback request is detected, the further procedure differs depending on the type of signaling. First, the incoming call of a callback requesting subscriber is either not yet accepted or accepted and held.
  • a caller number can also be assigned a callback number by means of the substitution list, but only a single one for the sake of clarity.

As with this, there is the possibility of the destination number by dialing, so e.g. by DTMF-coded number transmission over the voice connection to transmit.

Based on the signaling list, the call-back system device finally determines the signaling type and details thereof for the signaling to the callback system with the destination phone number.
  • the callback system device only calls the destination subscriber using the signaling given on the basis of the lists, if all checks in the sense of the callback system are positive; otherwise, as already described, it is advisable internally to a conventional callback system, which also serves as a supplementary application on the callback system Server system can be implemented, forwarded or, for example, to an automatic announcement or the incoming call from the callback requesting participant is rejected.

  • a tariff cost saving occurs when the tariff of the caller is cheaper than that of the caller, or when the caller calls out of the fixed network, because typically the billing rates of the telecommunications providers are such that a call from a mobile network in a fixed network cheaper is as the other way around.

  • the caller number serves as a signaling for a callback request.
  • the callback system device in Fig. 1 "listens" to incoming calls and immediately checks to see if the caller number is listed in the subscriber list. If not, then the callback system in Fig. 1 remains in place
  • An exemplary use case of the basic feature is a prepaid tariff child mobile phone and a parent cell phone having the inventive callback system facility and a flat rate tariff which also provides for connections to the child mobile phone cellular network Wirks If the child calls the parent mobile phone by means of the child mobile phone as a known and authorized subscriber of the callback system, the child is called back to the practically free flatrate tariff, which is at least much cheaper considering the basic costs.

  • the principle of the server characteristic is based on the basic characteristic. In this case, further types of signaling can now be used.
  • the connection to the recalling subscriber is preferably routed via the callback system server system 7 called subscriber C.
  • the principle of the server characteristic is based on the fact that the telecommunication terminal 5 or 6 of a subscriber A knows that a known subscriber B can be called with a telecommunication terminal 4 by means of a callback system. While the subscriber A on a callback request to subscriber B in the basic characteristics of the callback system on it and therefore should be prepared that his call is initially rejected and he now has to wait for the callback of B, the same connection recording is running in the Server version of the callback system in the preferred application now semiautomatic led over subscriber C or the callback system server system 7, transparent for A from.
  • E either hears the ringing tone until C connects it to the now available connection to B, or A For example, if an immediate call is accepted by C, a suitable automatic announcement is heard, such as "Please wait" until the connection can be switched to B. Due to the transparency of the callback system and suitable subscriber information by the callback system server System 7, the callback system must be activated user A no longer knows that he is using this callback system.This case occurs, for example, when another person uses subscriber A's mobile phone for a call and calls a callback system subscriber registered in the callback system facility of the mobile telephone.
  • a subscriber B must first verbally inform a subscriber A that he can be called by means of the callback system.
  • mutually the numbers and from B to A further details on the type of signaling communicated, because compared to the basic characteristics must now be initialized in the server version in the preferred application in which both participants mobile telecommunications terminals with the callback system device, both callback system facilities .
  • A inputs and stores the telephone number of B in the subscriber list of his mobile telephone with the callback system device and assigns the call number of C to the substitution list and the type of signaling for the connection to C in the substitute list Signaling list.
  • This one-time operation can be made very simple, depending on the complexity of the menu navigation and option management of the recall system, e.g. by activating a simple setting option "via server" in the settings menu of the callback system, in which case the number of A in the substitution list is automatically assigned to the call number of the callback system server system and again automatically default entries in the signaling list for this connection.
  • B must enter the telephone number of the telecommunication terminal 5 or 6 of A in the subscriber list of the callback system in its telecommunication terminal 4. Furthermore, for the preferred signaling of the Rufhummermodlot by a "99" for example for the two-digit number sequence XX before or a "12" for example, for the two-digit number sequence YY after the country code in the signaling list the call back to C, the call number from the callback system- Server system 7, registered. This is identical for every callback request made via C, which is why this can also be implemented as the basic setting of the callback system and is no longer used by the user. which must be carried out. However, B must also inform C in a suitable manner about the authorization of A as the callback requesting subscriber, so that the relevant lists in the callback system server system are initialized accordingly.
  • the transmission of the initialization data and the initialization of the participating callback system facilities can be done instead of verbally or manually in any other common and appropriate form.
  • a suitable interface to the user e.g.
  • This process can be centralized and simplified by means of a specific telephone service or via a special internet page or via a special initialization menu in the callback system device in the mobile telecommunication terminals, in which the input is only made at one point by the calling subscriber B and the corresponding ones Data in form eg a configuration SMS is sent to all other participants involved.
  • a now wants to call B then he dials as usual the telephone number of B. If B is a recall system known to the call-back system in A's mobile telephone, then it becomes active after the call button has been actuated or through a corresponding connection. It replaces the telephone number of B with that of C and calls C instead of B. At the same time it signals according to the information of the signaling list C the callback request and the destination telephone number.
  • the mobile telephone 6 signals via a data network and the landline telephone 5 via the connection-oriented connection, this must be done via call number signaling, because a landline phone by definition can not have the inventive device of the callback system. This is also just an optional application, not the preferred one.
  • the mobile phone 6 could also signal by means of call number signaling or by means of modified call number signaling via the connection-oriented connection.
  • the callback system server Once the callback system server has received the signaling and also the incoming call of the caller specified in the signaling A, recognizable by the caller ID, calls and signals itself B, provided positive identification and verification of A and B, and waits for the call rejection and then on the callback by or from B.
  • the upcoming call from A is not yet accepted or accepted and issued an automatic announcement to A, informing him that the connection is made equal, eg "Please wait!”.
  • the callback system becomes active as soon as B accepts the call by pressing the call acceptance key or by a corresponding procedure. It rejects the coming call of C, so that no toll call connection arises, and immediately calls itself back C. Subscriber B thus hears a ringing tone after picking up, which can be replaced by a specific tone or tone sequence under the control of the callback system device but also for the indication of a callback setup.
  • the callback system server system detects B's coming call, it establishes a connection between A and B in-server. It can not execute a callback, but only mediate.
  • An exemplary use case of the Serverausgargung is that of a frequently traveling person A, for example, a sales representative of a company XYZ with a mobile phone and a phone number RNA, under which he should always be reachable, even if he is abroad and there another SIM and RNC number of a local provider uses. Other sales representatives and family members and friends should always reach him by means of a mobile phone under the number RNA.
  • This is possible inexpensively by means of the callback system in the server version using a so-called Rufhummerfoli- service by substitution list.
  • the mobile phones of all persons involved must be equipped with the callback system device and their lists are initialized accordingly.
  • RNA phone number under which he is currently reachable
  • RNC any number RNC, as long as he is logged into the network. If an authorized subscriber B now calls the telephone number RNA, then the call diverted by the callback system to the callback system server system is forwarded there to A by means of the callback method, regardless of the caller's number currently having it communicated to the callback system server system. Caller B only ever receives the code into the landline to the callback system server system. Depending on the tariff used by A, this or his company also incurs the costs for the callbacks from the current mobile network to the fixed network. This also applies abroad if a server of the callback system server system is stationed there. This eliminates the roaming costs.
