Definitions
- the invention relates to a group communication system according to the preamble of claim 1 and to a group communication method according to claim 7.
- the invention relates to a group communication system, wherein the group communication system at least two
- Communication devices and in particular three or four or five or six communication devices, wherein the communication devices communicate in a radio network, wherein the radio network as a radio network after the one
- Standard works for the short-range radio, wherein over the wireless network primarily a voice communication between a group of people is performed, each person of the group carries a communication device with him.
- a person uses the group uses a teacher function of their assigned communication device, all other people in the group each use a student function of each associated communication device, the group communication system depending on a selection of which the person with teacher function and / or at least a person with student function is hit for the
- Group communication one of at least three
- Moderator mode is active in which the person speaks with the teacher function and hear all persons with pupil function, the second communication state such
- a subscriber mode is active, in which the person with the teacher function is connected to a person with student function through a full duplex connection and the other persons listen to students function and wherein the third communication state is designed such that a private mode is active in which the person with the teacher function is connected to a person with student function through a full-duplex connection and the other persons with student function are excluded from listening.
- a group communication system allows the person with teacher function to address the group or individual persons of the group in different ways, so that both a group lesson and a group lesson
- Short-range radio it is possible to use the group To operate communication device in virtually every country on earth, without violating national regulations for the use of radio frequencies.
- Communication devices by deviating from the A2DP Bluetooth profile, which is also referred to as advanced audio distribution profile, while avoiding the use of the A2DP Bluetooth profile underlying AVDTP Bluetooth profile, which also referred to as Audio / Video Distribution Transport Protocol is to establish a direct data connection between the communication devices, in which case necessary transmission parameters in the electronic units of the communication devices are wired so hard that between the electronic units of the communication devices a previous negotiation of the data connection is avoided. This allows the required data connections to be established quickly and without errors.
- the stream of audio data referred to as the audio stream
- the audio stream to be established between the communication devices in such a way that it is located between the communication device of the person with the teacher function and each one
- Communication device of a person with student function either in a first direction as a simplex audio stream or in a second direction as a simplex audio stream or as a full-duplex audio stream is established. This makes it easy and reliable to realize the different types of communication in the group.
- Monitoring mode is active, in which the person with the Teacher function hears all persons with pupil function and wherein the fifth communication state is formed such that a private and monitor mode is active, in which the person with the teacher function with a person with
- Student function is connected by a full-duplex connection and the person with teacher function is the other with
- the group communication system additionally or alternatively to a first and / or second and / or third communication state, a fourth and / or fifth and / or sixth
- Monitoring mode is active in which the person with the teacher function hears all persons with pupil function
- the fifth communication state is designed such that a private and monitor mode is active, in which the person with the teacher function with a person with
- Student function is connected by a full-duplex connection and the person with teacher function is the other with
- Communication state is designed such that a private and monitoring mode is active mode in which the person with the teacher function with more than one person with
- Student function is connected by a full duplex connection and the person with teacher function hears the other people with student function or by the other people with
- the group communication system can also be used to specifically address the communication requirements of a group.
- the group communication method according to the invention in which a group communication system is used, which is designed in particular according to at least one of the preceding claims and which at least three Communication devices includes, provides the following steps, wherein one of the communication devices is referred to as a master device and a communication device of a person with teacher function forms and wherein at least two other communication devices are referred to as slave devices and form communication devices of a person with teacher function, said Communication a Bluetooth wireless network is used:
- the group communication method provides SBC encoded audio transmission over the L2CAP channels while avoiding packaging this data into frames of a real-time transport (RTP) frame. This allows the audio data to be encoded with little delay.
- RTP real-time transport
- FIG. 1 shows a schematic representation of a group communication system in moderator mode
- FIG. 2 is a schematic representation of a group Communication system in the subscriber mode
- Figure 3 a schematic representation of a group communication system in private mode.
- FIG. 1 shows symbolically six communication devices K1 through K6 in a radio network FNW, which together form a group communication system GKS.
- the communication device Kl is designed as a teacher communication device LK, which is a person with a teacher function
- the communication devices K2 to K6 are designed as student communication devices SK, which are each assigned to a student.
- the group communication system GKS is in a first communication state or a moderator mode in which the person speaks with the teacher function and hears all persons with student function.
- Student function are excluded from communication with the teacher communication device LK.
- the group communication system is designed such that the transmission takes place via asynchronous ACL channels, wherein a point-to-point connection exists in each case between the teacher communication device acting as the master and the student communication devices functioning as slaves.
- This connection is used either as a duplex connection in both directions or as a simplex connection in one direction only.
- a duplex connection communication takes place between the teacher communication device and one of the student communication devices.
- one of the student communication devices In the case of one
- the teacher communication device addresses one or more student communication devices.
- the audio data of the respective communication are SBC coded and transmitted via L2CAP channels.
- the group communication system Furthermore, in the group communication system, the
- Signaling extended to e.g.
- the teacher communication device LK can remotely control the student communication devices SK and, for example, the audio function of a single student communication device SK can be activated by the teacher communication device LK.
- the teacher communication device LK can remotely control the student communication devices SK and, for example, the audio function of a single student communication device SK can be activated by the teacher communication device LK.
