Abstract

After a calling subscriber station triggers the creation of a voice communication to a called subscriber station, a condition for the creation of the communication is checked in a switching unit of the communication network. An input is required in the calling subscriber station in order to check the condition, and if the condition is met, a voice communication to the called subscriber station is created.

Method for the conditional establishment of a voice connection via a communication network and communication network

The invention relates to a method for the conditional structure ei ^¬ ner voice connection over a communication network, wherein said establishing a voice connection is released to a called subscriber station by a calling subscriber station, and a corresponding communication network.

The rapid technical development in the field of telecommunications has led to the development and provision of a large number of different telecommunications services in recent years. A particularly well-known and widely used service - which is activated, for example, in situations in which a subscriber to be called does not want to be disturbed - is the so-called voice mailbox service, which is implemented by an answering machine in a communication network. This service gives a calling subscriber station or a calling subscriber whose connection request to a called subscriber station or a called subscriber is rejected, the possibility of leaving a voice message in a storage device which the called subscriber station or the called subscriber can listen to it later.

However, for the calling subscriber station this is associated with costs for the voice message being recorded on the mailbox and secondly for the called subscriber station it is associated with costs for listening to the voice message recorded on the mailbox. It is also disadvantageous that all calls to this voice mailbox are forwarded to a voice mailbox of this type, even though the called subscriber has few particularly important calls, for example, even during a call. take court decisions or during the night against Wür ^¬ de.

The invention is therefore based on the object, a method for conditionally setting up a voice connection via a communica ^¬ cation network and specify a corresponding communication network, which enable that is disturbed to calling parti ^¬ mer in certain situations substantially only in urgent cases.

This object is solved by the features of the independent claims. Advantageous and expedient further developments result from the dependent claims.

According to the invention, the establishment of a voice connection to a called subscriber station is triggered by a calling subscriber station, a condition of the connection establishment is checked in a switching unit of the communication network, an input at the calling subscriber station being required for checking, and a voice connection when the condition is met to the called subscriber station.

By querying a condition before the final establishment of a voice connection or before the signaling of an incoming call to the called subscriber station, on the one hand, the called subscriber is prevented from being disturbed by each call to his telephone number, and on the other hand, it enables the called subscriber to be urgent Cases or in the case of calls from certain people even when he actually does not want to be disturbed and has, for example, set up a diversion of all calls to a voice mailbox. The input that is required for checking at the calling subscriber station is a further input that - in addition to the input of the Pααf number for triggering the connection establishment - is additionally required A development of the invention provides that for checking the condition of the calling subscriber station, an identifier is entered, the identifier input is compared with a in the switching device or the associated device stored identifier, and the Bedin is ^¬ supply satisfied when the entered and the stored identifier match. This further development is based on the idea of assigning a subscriber a second identifier in addition to his telephone number. Unlike the phone number, this identifier is not necessarily required to establish a connection to this subscriber. This identifier is only queried if the "Conditional connection establishment" feature described above is activated. By storing a subscriber-specific identifier in a switching facility and forwarding this secret number to a certain group of people, such as family, friends or colleagues, it is achieved that only the specific group of people is able to establish a voice connection to the by entering the secret number to build calling participants and thus to disturb them.

Another development provides that an announcement containing the identifier is transmitted to the calling subscriber station before the identifier is entered at the calling subscriber station. This enables, for example, an announcement to be made after a connection has been set up by a calling subscriber station: "The called subscriber currently only wants to be disturbed in urgent cases. If you want to disturb the called subscriber now, press 1 (ID). To go to an electronic voice mailbox, press 2. " This leaves it up to the calling subscriber to decide whether he wants a voice connection and thus a disruption to the called subscriber despite the particular situation in which the called subscriber is. Further provides an embodiment of the invention is that the device of the related configuration of a speech ^¬ described connection from the subscriber station to be called by ^¬ can be guided, for example by an appropriate input at the keyboard to the calling subscriber station.

To achieve the object, a communication network is also specified, which is set up in particular to carry out the method according to the invention or one of its developments.

The invention is described in more detail below on the basis of preferred exemplary embodiments, the figures listed below serving to explain them:

FIG. 1 block diagram of a mobile radio network;

Figure 2 message flow diagram of a method for the conditional establishment of a voice connection.

In FIG. 1, a cellular mobile radio network is shown as an example of the communication network, which consists of a multiplicity of mobile switching centers MSC, which are networked with one another or enable access to a fixed network PSTN. Furthermore, these mobile switching centers MSC are each connected to at least one base station controller BSC, which can also be formed by a data processing system. Each base station controller BSC is in turn connected to at least one base station BS. Such a base station BS is a radio station which can establish a radio connection to other radio stations, so-called mobile stations G_MS, R_MS, via a radio interface. Information or data can be transmitted between the mobile stations G_MS, R_MS and the base station BS assigned to these mobile stations G_MS, R_MS by means of radio signals. The transmission of the data can be carried out according to methods known per se for data transmission within predetermined frequency channels. le, which can also be described by the corresponding carrier frequency.

The range of the radio signals of a base station essentially defines a radio cell FZ. The totality of all radio ^¬ cells of a mobile network thus determines the Abdeckungsbe ^¬ range of the mobile network.

Depending on the embodiment variant, a processor device PE together with a memory device SPE can be integrated in a base station controller BSC, a mobile switching center MSC (shown in the figure) or another central device of the mobile radio network, which is set up in terms of program technology to carry out the method according to the invention or its further developments is.

For the transmission of data, in particular voice data, a connection is established from a calling mobile station R_MS to a called mobile station G_MS by means of signaling methods known per se by means of the mobile radio network and then data is transmitted by means of known transmission methods.

The message flow between a calling mobile station R_MS and a called one is shown below with reference to FIG

Mobile station G_MS is described via a switching device R_MSC of the calling mobile station R_MS and a switching device G_MSC of the called mobile station G_MS, the establishment of the conditional connection being set up in the switching device G_MSC of the called mobile station G_MS. In contrast to the example described with reference to FIG. 1, the called and the calling mobile station are located in different radio cells, which in turn are assigned to different switching devices (mobile switching centers). In state 1, the feature "Conditional connection ^¬ building" is not activated. Depending on whether or not redirection to the voice mailbox is set up, all calls destined for the called mobile station G_MS are forwarded to the voice mailbox or to the called mobile station G_MS.

In step 2, a corresponding message is generated at a mobile station G_MS to be called and activated to the switching device G_MSC of the mobile station to be called in order to activate the "conditional connection establishment" feature. The generation of the message in the mobile station G_MS to be called can be triggered either by a corresponding subscriber input using the keyboard or automatically by selecting a specific user profile which describes certain settings of the mobile station G_MS to be called.

Appropriate processing of this message in the switching facility G_MSC of the mobile station to be called leads to state 3, in which the “conditional connection establishment” feature is activated for calls directed to the mobile station G_MS to be called.

If the call number of the called mobile station G_MS is now entered in step 4 at the calling mobile station R_MS, a connection setup is triggered in step 5. It is recognized in the switching facility G_MSC of the called mobile station G_MS that the performance feature "conditional connection establishment" is activated for the called mobile station G_MS. Therefore, the desired voice connection is not initially established, but instead the following announcement is sent to the calling mobile station R_MS in step 6: "The subscriber you want only wants to be disturbed in urgent cases. Select 1, if you still want to be connected, select 2 to be connected to the subscriber's voice mailbox. " Would now be at the at the calling mobile station R_MS "2" is ^¬, no voice connection to the called mobile ^¬ would be built station G_MS; instead, a connection is established or a call is diverted to the voice mailbox or

Connection establishment is terminated. If, on the other hand, "1" is entered in step 7 on the calling mobile station R_MS, a connection is established in step 8 to the called mobile station G_MS. For this purpose, a ringing tone is output at the called mobile station G_MS, for example, which prompts the subscriber of the called mobile station G_MS to accept the call. The acceptance of the call in step 9 leads to state 10, in which after the complete establishment of the voice connection there is a voice connection between the calling mobile station R_MS and the called mobile station G_MS.

By pressing a "end call key" on the calling mobile station R_MS in step 11 or the called mobile station G_MS in step 13, a connection termination is triggered in step 12, which results in the state 14 "call ended".

In step 15, in order to deactivate the “conditional connection establishment” feature, a corresponding message is again generated at the mobile station G_MS to be called and transmitted to the switching device G_MSC of the mobile station to be called. Appropriate processing of this message in the switching facility G_MSC of the mobile station to be called leads to state 16, in which the “conditional connection establishment” feature is deactivated again.

Another embodiment of the invention provides instead of steps 6 and 7 described above that the following announcement is transmitted to the calling mobile station R_MS: "If you want to be connected to the subscriber X you want, enter the subscriber's connection ID X a. " Now at the calling mobile station If an identifier is entered for R_MS, in particular in the form of a secret number, it is transmitted to the switching device G_MSC of the mobile station to be called and compared there with an identifier stored for subscriber X (user of the called mobile station G_MS). If the entered and stored identifier match, a connection is set up to the called mobile station G_MS; otherwise a connection is established or a call is diverted to the voice mailbox or the connection is terminated.

In addition to the above-described embodiment variants of the invention, a large number of further embodiment variants are within the scope of the invention, which are not described further here, but can simply be put into practice on the basis of the illustrated exemplary embodiments. In particular, this can be corresponding implementations in a fixed network environment.
