Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a schematic representation of a communication system according to the invention which includes a docking station according to the invention, and

(2) FIG. 2 is a flow chart for an embodiment of the invented method.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

(3) FIG. 1 is a schematic representation of a present preferred communication system 60 according to the invention having a communication infrastructure 8, which may, for example, be a local area network or wide area network of a company. A tablet PC 90 or other mobile communication device can be connected to the communication infrastructure 8. The tablet PC 90 is usually connected to a communications network 29, such as a wireless infrastructure (WLAN or cellular network). Generally the tablet PC 90 or other mobile communication device will be outside of the company IT structure to which it is to be connected. The tablet PC 90 contains an NFC and/or Bluetooth interface, or has an RFID adhesive label. The tablet PC 90 or the adhesive label attached to it stores, in addition to information for establishing a P2P connection to a docking station 10, a certificate 40. That certificate contains authorization information that was issued by the infrastructure management of the company to which the tablet PC 90 is to be connected. Alternatively, the certificate could be a certificate issued by a third-party but authorized by the respective companies whose communication infrastructure will be accessed by the mobile device. The NFC or Bluetooth interface 93 generates a wireless transmission, by which the tablet PC 90 can signal its presence in the vicinity of the docking station 10. In addition, this interface is used to transmit the certificate 40 to the docking station 10.

(4) The docking station 10 in turn comprises a cradle 12, which is shown in FIG. 1 as a rounded surface, for setting down, or storing the tablet-PCs 90. The cradle sits on a transfer device 20 which has a housing that supports the cradle and other components of the docking station. If desired the cradle may be integrally formed with the housing. Alternatively the cradle may not be attached to or rest on the transfer device 20. In addition, the docking station 10 includes a detection device 23 (for example, an RFID circuit) for detecting the presence of the tablet-PCs 90.

(5) The tablet-PC 90 and the docking station 10 each have a P2P wireless interface 14 to establish an appropriate communication link 24. The docking station 10 also comprises an Ethernet interface 16 to establish an additional communication link 26 (Ethernet connection) with the communication infrastructure 8 of the company. The detection device, authentication device, first interface, second interface and transfer device can be attached to either or both of the housing and the cradle.

(6) Once the tablet-PC 90 comes close to or within the radio range of the docking station 10, this approach is detected and the certificate 40 is transmitted to the docking station 10 via the NFC-/Bluetooth interface 14. The certificate 40 is validated through a dedicated or shared service—which can be local or in the cloud—which then sends the data required to establish a P2P connection from the tablet PC 90 to the docking station 10. The docking station 10 then establishes the P2P connection via WLAN. This connection is then passed to the LAN 26 by means of a transfer device 20 in the form of an Ethernet switch and/or router in the docking station 10.

(7) It should be noted that the tablet PC 90 only represents the mobile communications devices or telecommunications devices that can be connected to the communication infrastructure 8 by means of the present invention using the docking station 10.

(8) If the WLAN connection 24 between the tablet PC 90 and the docking station 10 breaks, the connection to the LAN 26 is also interrupted. The tablet PC 90 then switches to the preferred wireless network 29 and logs itself in into the wireless network 29.

(9) The docking station 10 also preferably has built-in speaker 19. This speaker 19 can be used to improve the audio quality of the docking station 10—either in addition to or instead of using the speakers of the tablet PC 90. The docking station 10 also preferably includes a connector for connecting an external display 17, which can be used for the replication of the tablet PC 90 display on an external monitor, if the tablet PC 90 permits. Alternatively, the docking station may support the wireless connection of playback devices, such as via the “Digital Living Network Alliance” DLNA standard (see http://www.dlna.org/ or wireless USB.

(10) A firewall 18 is also preferably integrated in the docking station 10 that can reliably prevent malware or unwanted software to pass via the docking station 10 onto the communication infrastructure 8. The firewall can be software in a non-transitory memory and provides that protection without regard to the configuration of the communication device 90 to be connected via the docking station 10 to the communication infrastructure 8. The docking station 10 also preferably includes a memory 13 that stores the authentication key that identifies the docking station in question as the standard docking station for a specific communications device 90. This way, the corresponding communication device 90 can immediately be connected to the communication infrastructure 8 via the docking station 10 without validating the certificate via an appropriate service. The validation and the connection are therefore possible even if the validation service is not currently available.

(11) The docking station 10 also preferably comprises a universal charging station 11 for charging the battery of a communication device 90 connected via the docking station 10. Preferably the charging station can charge that battery wirelessly regardless of the specific configuration and features of the communication device. This considerably improves the convenience of the docking station 10 and the versatility of its use.

(12) The docking station 10 preferably further includes an Ethernet port (not shown) to which for example a PC can be connected, according to the principle of “one-wire-to-the-desk” or “only one cable to the desk”.

(13) The external monitor 17 can be connected, for example via an HDMI, DVI or VGA cable to the docking station 10.

(14) The use of a mechanical switch or a press-contacting surface (on which the communication terminal 90 can be placed) can be provided instead of, or in addition to, the above-described capability of a wireless detection by the docking station 10 of the approach or presence of a communication device 90.

(15) It should be noted that, with the present invention, any mobile communication device such as smart phones, tablet PCs, etc. can be connected to a company's IT structure in a safer, more convenient and flexible way. By using the peer-to-peer wireless connection, traffic can be diverted advantageously from the WLAN infrastructure that would or could otherwise be used by the mobile device.

(16) The sequence of a present preferred method according to the invention for connecting a mobile communication device 90 to an at least partially wire-based communication infrastructure 8 of a company is summarized in FIG. 2. In step S1, a Near Field Communication (NFC connection) or an RFID connection is first established between the tablet computer 90 and the docking station 10 as soon as the tablet PC 90 has come within a selected distance of the docking station 10 at which that connection can be established. Thereafter, a certificate 40 is sent from the tablet PC 90 to the docking station 10 via the aforementioned link (see step S2). In step S3, the certificate 40 is checked. If the certificate is valid, a P2P wireless connection between the tablet PC 90 and the docking station 10 is established in step S4. This connection is then passed in step S5 to the LAN which connects the docking station 10 to the communication infrastructure 8. After that, the communication between the tablet PC 90 and the company can take place in step S6. This communication is maintained as long as the P2P wireless connection between Tablet PC 90 and the docking station 10 as well as the LAN connection 26 between the docking station 10 and the communication infrastructure 8 works. As indicated in step S7 when a check of the proper functioning of this connection indicates that it no longer or adequately works, the tablet PC 90 automatically switches according to step S8 to a communication with a wireless network 29 of his choice so that it maintains at least some communication capabilities. For example, that wireless network may provide Internet access, but may not provide access to the company communications infrastructure.

(17) It should be noted that the described characteristics of the represented embodiments of the invention, such as the type and design of the individual equipment parts, interfaces and communication links may be otherwise embodied within the scope of the following claims, unless otherwise stated or prohibited for technical reasons.
