Method for realizing a telecommunications service in an intelligent communications network, which connects at least one first and one second telecommunications terminal, and method for implementing in a communications system

p0001A method for implementing a telecommunications service in a least a first and a second telecommunications terminal connected intelligent communications network and method for performing in a communication system

p0002The invention relates to a method for implementing a telecommunications service in an intelligent communications network (IN) according to the preamble of claim 1 and a telecommunication system for implementing the method according to the preamble of patent claim 10th

p0003Telecommunications services in communication networks, in addition to basic services, such as the transmission of data, and other services offered by the network. Known services include the ability to provide specific numbers for service user, the use of which has a different charging result, as well as Virtual Private Network (VPN) or Universal Personal Telecommuniea- tions (UPT).

p0004In public networks, these services can in special centralized facilities - puters as powerful Com - be implemented. The amendment of existing and introduction of new services are made only on centralized control points. An example of such a centralized service control is the intelligent network (Intelligent Network, IN), which has been standardized in its Grundar- architecture of ETSI (European Telecomunication Standards Institute) and ITU-T (International Telecomunications Union) according to the Q.1200 series is.

p0005The basic idea of ​​the intelligent network is the separation of switching functions and service functions. The mechanisms that build a connection are no longer fully in the individual exchange, but are centralized in a powerful computer, also called service center, from where they can be easily changed. From here, corresponding data will be passed to local exchanges that control where call setup to another comparison.

p0006So far, new services for participants could only be offered once the local exchange of the subscriber was reequipped for it. This led to expensive conversion processes and long lead times for the introduction of new services. In solving the centralized control of change and / or introduction of services on the other hand, a retrofitting of individual exchanges is no longer necessary.

p0007Is called within a telecommunications service in an intelligent network, the call is performed by means of a connection request of a subscriber of the network. For this, a service number, for example, is elected an IN prefix ( "01") and a service code ( "80") of the participants. An IN-enabled switching center (SSP, Service Switching Point) can detect the presence of an IN service using the selected numeric string "0180" by comparison with the content of an interdepartmental called trigger table. The contents of the trigger table is set and changed by the network operator. The trigger can Aside from the choice of the service number and connection states such as "busy", "no answer" and "stand" act.

p0008If the switch is not designed for use in intelligent networks, through a predetermined connection route to connect to an assigned IN-Ver is built ittlungsstelle and transmit the dialed string as a parameter to this.

p0009Once the presence of an IN service is detected in the switching center, the reference to the IN-Services- begins kennzahl selected service as a function of an associated application program to expire, which is selected by the trigger table. The service is by_Anwendungsprogramm in a service control point (SCP, Service _Control Point) realizes and controls the further handling of the call. This procedure is described in the ITU-T Recommendation Q.1214.

p0010A possible sequence of the telecommunications service, the announcement of an announcement device of the IN be, for example, is in an Intelligent Peripheral (IP), which allows the participants a management of the service arranged. The subscriber can then by virtue of a software menu which he desires information from the OGM device specific calls. In addition, the intelligent peripheral to the participant's request, which uses a first calling terminal to accept, to establish a connection to a second terminal. The then called by the telecommunications service subscriber who uses the second terminal, but can not achieve a change of affiliation with use of the service.

p0011Accordingly, the present invention seeks to provide a method for implementing an IN telecommunications service indicate which is initiated without a call from a service user and each of the IN service relevant in every terminal is allowed to change a connection.

p0012This object is achieved proceed according to the features of claim 1 and apparatus according to the features of claim 10th

p0013An essential point of the invention is that of telecommunications services by a first telecommunication terminal in the service center first activated and then by an automatically executed movement of such data starts the same without the help of the first terminal. Then, in an experiment conducted by the service call at least a first connection with the intelligent network is set up, which can reduce a the terminal-use subscriber at his own request again to get up a second connection.

p0014Accordingly, it is not necessary to start the service within the intelligent network, which allows the first and further terminals send an announcement message by calling the terminal. Rather, the service automatically after it is activated by the first terminal to the answering mode by means of an application program (also called IN Service Logic) after an automatic start due to a previously conducted data comparison by.

p0015The first connection is preferably established between an announcement device or another communication device of the intelligent network and the first and / or at least one other terminal, while the second connection between the first and / or further terminal and a second and / or further terminal is established. This terminal can be configured as a different form of telecommunications device, such as a telecommunications system or a call center representative means the second and / or other well.

p0016For such automatic start of the service, the application program is triggered by a trigger in a preferred embodiment, the start in the form of a "virtual phone number", which is initially generated by the central unit and is transmitted to a service provider within the intelligent network, triggered or , This "virtual number" is used for (SSP) to be recognized as a service call and from the SSP to the service center (SCP) to be dispatched for execution of the application program in an IN-enabled switching center. The "virtual Number "for example, can then be sent to the central office when a data comparison leads to a positive result. In this way is a start of the service, which has been initiated by a connection request of the first terminal, made possible by a different type of event.

p0017Upon activation of the telecommunications service reference data from the first terminal whose user occurs later as one of the service user input. The reference data split into connection data and content data. The link data include this example, the telephone numbers of the party to be called by the service terminal, whereas the content data hold those data contain, which are to be carried out in the later data compared with data that are transmitted from the second terminal, compared. From the comparison result of the launch of the service is made conditional. In addition to these data parameters are input, such as input formats, times and conditions are intended to prevent a start of the service. Similarly, several numbers of the various terminals of the participant who has initially via the first terminal activates the service, can be entered. This ensures the availability of the subscriber in a call to be performed later by the service.

p0018The arranged in the service center application program calls after starting the service on the first and other terminals to establish with them a first connection to an announcement device of the intelligent network, which may be configured for example in an Intelligent Peripheral. Participants will - after having a predetermined announcement message based on the comparison results obtained - prompted by the service center via the IP to send a first message on the desired structure of the second connection to the second terminal to the service center. In this way they can have a Change the connection that existed previously with the announcement device, initiate. The service center then causes the breakdown of the first compound and the construction of the second connection between the first and further devices on the one hand and the second terminal on the other hand on the switch.

p0019A second message including request signals for requesting the transmitted data and / or the comparison results or other data, is sent from the first and / or further telecommunication terminal to the service center. By means of this second message, which can be transmitted chronologically before the first message, a service user has the ability to query for example, cancellation data that are necessary to cancel the flight.

p0020According to a preferred embodiment, the messages on the desired structure of the second connection can by means of a voice storage system, such as Interactive Voice RESPONSE (IVR) can be queried by the service center. The user of the terminal may then signal by pressing a button in a simple way the message to the service center.

p0021A telecommunication system with a service control point in an intelligent communications network (IN) has advantageously to perform the method a first memory means for storing the application program, a second memory means for storing reference data, and other activation data, comparing means for comparing the enthalteneen in the reference data content data with the transmitted data and means for assembly and disassembly of the first and second connection.

p0022Further embodiments result from the dependent claims. Additional benefits and advantages can the following description in conjunction with the drawings are taken. In the figures:

p0023Fig. 1 is a schematic representation of the method involving apparatus aspects, and

p0024FIGS. 2a and 2b is a flow diagram of an embodiment of the method.

p0025Fig. 1 shows a communication network IN, which has the possibility of realizing centralized services provided. A first terminal 1 is like a second terminal 3 with an intelligent network 2 via a service center 4 (SCP) connected. In the service center 4, the application program is set up, representing the Service Logic of service.

p0026About an intelligent peripheral 5 is an announcement establishing the IN with the service center 4 and a switching center 6 (SSP), which is designed for smart grids, respectively. About the exchange 6 more terminals 7 are connected to the intelligent network.

p0027In a first step Sl of the participants, which uses the first terminal 1 is activated, the service in the service center 4 through the transmission of reference data. The reference data includes link data over those connections via which information, in particular announcement messages are to be sent and content data hergenommen for a cross-check. The service center 4 thus receives the necessary data for later execution of services such as the telephone numbers of ac- tivierenden participant and other telephone numbers of other

p0028Participants to call their terminal later. The phone numbers are among the connection data. include contrast to the content data, the data to be compared, because of their comparison result takes place starting of the telecommunications service.

p0029_Aus this information generates the service center 4 is a "virtual number" as a trigger that is used to start the service. This virtual number will now be sent to a service provider, not shown here, or a suitable other communication device that can communicate with the second terminal. 3 Alternatively, data can be retrieved from the second terminal via the service center 4 (step S2) and launched in the presence of all relevant data of the actual telecommunication service in a query mode.

p0030After the presence of the transmitted data in a step S3 compared these to the content data that has been entered during the activation process. If the predetermined by the service comparison results are available, in a step S4, an announcement message is generated by the service center and transmitted in a step S6, the announcement device and the switch 6 to the terminal to be called. For this purpose, a controlled carried by the service center 4 call to each of the terminals 7 (step S5).

p0031With the announcement message, the participants of the terminals 7 are prompted to specify whether they want to change this first connection with the announcement device. Provided that the terminals 7-use Participants may affirm in an IVR method, for example by pressing a button (step S7), the first connection is terminated with the announcement device and a second connection to the terminal 3 through the switch 6 and the service center 4 built up ( step S8). Figures 2a and 2b show the flow diagram of one embodiment of the inventive method using the example of an information service for passengers. This information service for passengers to check for delays. The passenger activated this a "Delay Notification Service" in the service center (step Sl), by transferring a flight number, the date and time of departure to the service center as content data. Furthermore, he calls the latest call time, for example by typing "call until 14:00". He additionally configured call destinations as connection data, may be a terminal, for example, a person who is to pick him up at the arrival point. He can also specify additional numbers of additional terminals belonging to him.

p0032In a step S2, a call center received a Flughafengesellschaft the ursprüngichen flight number and flight number as well as the new departure times after notification of a delay to the smart grid. In a step S3 takes place in the service center, a data comparison with respect to the flight number and the identification of passengers to be recalled instead. In such a data comparison will be verified within the service center if a request on the part of the subscriber who uses the first terminal, is present on the specific flight number. If this check is in the affirmative, accessing a memory table as content data, the flight times, which are assigned to the respective flight number implies. When a comparison of flight times leads to the finding that a delay of

p0033Flight is present outside a predetermined time frame, is accessed to all telephone numbers that the subscriber has previously transmitted during the activation process as a connection data. Then generate the service center in a step S4, an announcement message, the contents of the delay of the departure of each of these numbers is to be sent. In a step S5, the service center calls initiated to the terminal of the passenger and terminals Another participant, in which the announcement device is arranged a connection between the intelligent peripheral, and the terminals builds.

p0034_Anschließend starts the service center in a step S6, the transmission process for sending the greeting message to the passenger and other participants.

p0035In a step S7, the service center initiated by a software menu, a voice messaging system (IVR), which the other participants as well as the passenger has a waste wonder mode offers the option sent further information for a cancellation of the flight, for example, by e-mail to get. Furthermore, the participants of the other terminals will be prompted to send a message over a desired configuration of a second connection between the terminals of the passenger or the other party and the call center of the carrier to the service center. Provided that the other participants have sent such a connection request as a message to the central Services- which different numbers accessing a spectral in Dienstezen- arranged storage area includes. There is then a function of the respective participant who expresses such a connection request, the assembly of a telephone number data set, which may contain, among other things, the number of the Deutsche Bahn, which can be used connection for late flight connection as a replacement. Participants Unless during the inquiry conducted by the Software menu INXpress selection for a second connection to the airline decide in a step S8, this connection is established via INXpress. In addition, a breakdown of the first connection between the terminals of the participants and the Intelligent Peripheral durchgeführ. The part- participants can thus automatically initiate a change of connections.

p0036All features disclosed in the application documents are features essential to the invention claimed, so far as it individually or in combination, over the prior art are new.
