Definitions
- Such group communication systems are commonly used in applications where use of a network provider, such as a telecommunications service provider, is not possible or desirable.
- a disadvantage of communication systems concerned is that the bidirectional communication, in particular the simultaneous speaking and listening, is limited. Reason for this is that only one bidirectional
- Channel for example, for speaking and listening, can be opened, and that further participants of the
- Network operators and teleconferencing systems with central administrative units are known, allow a
- Object of the present invention is therefore to develop group communication systems in particular their
- the invention relates to a method for operating a group communication system (GKS), wherein the group communication system at least three communication devices, preferably a plurality, for example, 6 and more
- the communication devices are equipped with technology to communicate in at least one wireless network, each communication device at least for the transmission of a sound in particular
- Voice signal provides a communication channel.
- the invention is characterized in that a direct
- Each communication channel is bidirectional
- a network provider in particular a network node, for example in the form of a transmission tower of which all communication devices
- a radio network connection in particular a LAN, is used for the radio connection, for example.
- the radio connection via a mobile network connection, in particular via a
- Each communication device has and provides a router function. In this way, it is possible to divide group communication systems into groups again, with each communication device being between two relevant groups of communication devices between them
- each communication device has an address server function, in particular a dynamic address allocation
- the communication devices have a unique internal address, which is present for example in the form of a hardware address or a unique personalization of the devices. If a group communication system is now established, one of the
- Communication devices an address server function and allows the other communication devices as participants in the
- the communication device with the address server function assigned identifications, whereupon the direct communication of all devices can be established with each other.
- another communication device can take over the address server function and also allow and address other communication devices to the group communication system.
- Each communication device may therefore, depending on the operating state, be able to invite further communication devices to the group communication system in order to participate in the network of direct communication between all the devices.
- the allocation of the identifications is preferably carried out
- each communication device has a repeater function
- the function of the repeater allows group communication systems to have longer ranges
- provided repeater function participates in the direct speech-Hörthetic or only passes through the communication channel.
- the Communication device also provides a bridge function.
- the bridge function can be similar to the
- GKS group communication system
- an ad hoc network offers the advantage that, independent of the presence of any network operators or other infrastructures, a group communication system according to the present invention can be established.
- the ad hoc network is thereby spanned by the communication devices themselves with no central network account or the same is defined, but rather a network of meshes of all devices with each other with connections of the devices with each other (so-called mesh network) is established.
- the group communication system GKS a plurality of Subgroups GKS-I and GKS-II, the subgroups with each other some, especially all
- At least one communication device is connected as a network bridge or as a router between a plurality of ad hoc networks, consisting of a plurality of communication devices, for providing an overarching group communication system.
- Router functions a direct communication, to
- the group communication system has an interface to an external network, in particular to the Internet, wherein the
- the group communication system Due to the accessibility from an external network can over the interface, for example, from the Internet, the group communication system called and contacted. In this case, either communications can be transmitted to the entire group communication system, or only individual communication devices or subgroups of several communication devices are addressed.
- FIG. 1 shows a group communication system BIP with a total of four communication devices K1, K2, K3, K4.
- this communication device Kl would then use the other communication devices K2 to K4 to participate in the
- Each communication device Kl to K4 has a direct communication to all other devices, each one
- Communication channel is designed as a bidirectional communication channel. For example, that communicates
- the communication device K2 communicates with the
- a headset 10 is shown in the form of a headphone with microphone.
- the headset 10 includes while headphones 11 and a microphone 12 wherein the headphone audio playback 13 and the microphone
- Audio recording 14 takes place.
- the headset 10 can be connected to the communication devices Kl to K4 either via a
- Connection 16 for example a Bluetooth connection
- FIG. 2 shows by way of example a further arrangement of FIG
- Communication channels CHxy between the communication devices K1 to K7 are corresponding to the system of FIG. 1
- Group communication system are enabled.
- Routing function of the communication device K2 are interconnected. This way can be a direct
- Communication between K1 and K5 is made via the routing function of K2 and a bi-directional speech-to-hearing connection is provided.
- GKS-I and GKS-II The range of the group communication system GKS-I, formed from K1 to K5, does not fully cover the range of the group communication system GKS-II formed of K6 and K7. It is not possible to connect all communication devices via one
- Range limit 30 addition completely directly.
- geographical conditions can also lead to problems of direct communication, such as
- the channels CH67, CH46 and CH24 In order to establish a communication link between K7 and K2, the channels CH67, CH46 and CH24 must be connected in series, so that the communication devices K4 and K6 fulfill a repeater function and the bidirectional
- Radio links wherein the radio links are provided either directly or through the corresponding functionalities by other communication devices.
- an interface 40 to an external network is shown on the communication device K7.
- the interface 40 is presently wireless Interface formed with an antenna 41, which accesses the Internet, for example via a mobile Internet standard, in particular LTE or other standards.
- signals 42 can be sent to the Internet and calls from the Internet can be received.
- data connections of all kinds are additionally conceivable.
