Definitions
- the invention relates to a method for communication in a wireless communication network, in which a portable communication device is connected during a connection to a stationary communication device via a first wireless communication channel, which is part of a first communication network and which has a first information width. Communication information that is received via the communication channel is output on the portable communication device.
- the invention also relates to an arrangement for communication in a wireless communication network with a transportable communication device which has a first transmitting and receiving unit and at least one first information output unit, and with a first stationary communication device which is part of a first communication network and which has a second transmitting and has a receiving unit which corresponds to the first transmitting and receiving unit.
- a portable communication device is connected during a connection to a stationary communication device, for example a converter, via a first wireless communication channel, which is part of the radio telephone network.
- the information width realized is sufficient to transmit voice, video or text information.
- Communication information that is received via the communication channel, ie voice, video and text information, is output on the portable communication device.
- Bluetooth For more independent handling of a radio telephone or a similar communication device, it is known under the brand name "Bluetooth" that the communication information is transmitted wirelessly to a second, lighter, portable communication device that can be worn on the head, for example. This makes it possible to make a phone call independently of the radio telephone.
- LAN local area network
- WLAN wireless local area network
- FWA fixed wireless access
- communication information in the ⁇ -wave range is transmitted between communication devices.
- W-WAN wireless wide area network
- the FWA method also has the disadvantage of a relatively low bandwidth and the need for a quasi line of sight between the network participants.
- the object of the invention is now to improve the presentation of the received communication information.
- this task is solved in that the communication information in the form of digitized video and audio information is transmitted with a first information width.
- the transportable communication device is connected to a second stationary communication device via a second wireless communication channel, which has a second information width.
- the communication information is at least partially sent to the second stationary communication device and output there.
- the second information width is at least equal to the first information width.
- the communication information consists of audio and video information and that the audio and / or video information is sent to the second stationary communication device and output there.
- the second communication channel is part of a second communication network.
- the second stationary communication device is also a subscriber in the LAN.
- the information sent wirelessly by the portable communication device on the second communication channel can be received by the second stationary communication device and passed on to the LAN.
- the transportable communication device can become a direct participant in the W-LAN and for the communication information to be sent to the second stationary communication device via the W-LAN.
- the method is also developed in that the second information width is equal to or greater than the first information width and that the received communication information is converted in the transportable communication device to a transmission format of the second communication channel.
- the portable communication device can temporarily store data that arrives with a small first data width and forwards it with a larger second data width.
- the implementation of the communication information is useful, as in all 'rule log archiving le of the first and second communication channels are different. This means that the entire process can also be used for such different protocols. It is also possible to design the method in such a way that the connection of the transportable communication device to the second stationary communication device is established automatically when the transportable communication device comes within range of the second stationary communication device.
- the task according to the invention is achieved in that a second stationary communication device is provided, which has a second information output unit and a receiving unit, and in that the transportable communication device has a transmitting unit which corresponds to the receiving unit and an interface between the second transmitting unit - And receiving unit and the transmitting unit is provided.
- the transportable communication device In addition to the first transmission and reception unit, the transportable communication device also has at least one additional transmission unit. Via the interface, the communication information that was received on the first communication channel is then sent to the transmitting unit, which then sends the communication information to the receiving unit in the stationary communication device. This can then e.g. in addition to the output on the first information output unit on the second information output unit.
- Such W-LAN interfaces can be implemented in a size that can be physically very well integrated into a smaller, portable communication device. There are also no problems in providing the required energy.
- the arrangement according to the invention can be further developed in that the second stationary communication device is part of a second communication network.
- the portable communication device can itself be a participant, e.g. in a wireless network.
- a further embodiment of the invention is characterized in that the first information output unit contains a first screen and the second information output unit contains a second screen, the second screen being larger than the first screen.
- the transmission unit is part of a third transmission and reception unit and the reception unit is part of a fourth transmission and reception unit.
- This configuration makes it possible for the second communication channel not only to be used to pass on communication information to the second stationary communication device, but also vice versa.
- microphones can be installed in a conference room via which the voice input takes place, which is then forwarded to the portable communication device via the second communication channel.
- the portable communication device 1 is designed as a cell phone.
- the portable communication device 1 is connected to a first stationary communication device 2 via a first communication channel 3.
- the first stationary communication device 2 is a member of a first communication network 4, in this case a radio telephone network constructed as a W-WAN.
- a video conference is connected between the first stationary communication device 2 and the portable communication device 1, i.e. audio and video data are exchanged via the first communication channel 3.
- a first transmission and reception unit 5 in the first stationary communication device 2 is connected to a second transmission and reception unit 6 in the transportable communication device 1.
- the video information is displayed on a first information output unit 7 in the transportable communication device 1, but in one unsatisfactory size and quality.
- a transmission unit 8 is also arranged in the transportable communication device 1. This is connected via an interface 9 to the second transmitting and receiving unit 6. As a result, communication information received by the second transmission and reception unit 6 can be forwarded to the transmission unit 8.
- a second stationary communication device 10 is also provided in the arrangement. This is provided with a receiving unit 11.
- the transmitting unit 8 now sends the communication information to the receiving unit 11 via a second communication channel 12.
- the communication information is face 9 converted to format that corresponds to the protocol in the second communication channel 12.
- a second information output unit 13 is arranged in the second stationary communication device 10. The communication information is then output in a better size and quality on this.
- This second information output unit 10 is a large wall-mounted plasma screen with a stereo audio playback system.
- the receiving unit 11 is connected in a suitable manner in the second stationary communication device 10 to the receiving unit 11.
- the second stationary communication device 10 is part of a second communication network 14, in the form of a WLAN.
- the connection in the second communication channel 12 is established automatically when the portable communication device 1 comes into the reception area of the second communication network 14. This allows a person to enter the reception area of the second communication network 14 while the connection is being established via the first communication channel 3, in order to be able to follow the video conference in substantially better quality.
- transportable communication device first stationary communication device first communication channel first communication network first transmitting and receiving unit second transmitting and receiving unit first information output unit transmitting unit interface second stationary communication device receiving unit second communication channel second information output unit second communication network
