System and method for cohesive radio operation

[0001] A standard system may use a radio transceiver that operates according to a standard wireless communication protocol (e.g., IEEE 802.11 standard). The system may contain multiple wireless devices that communicate with the central computer using one or more access points. As defined in the 802.11 standard, these communications can use the 2.4 GHz frequency band. The system may further comprise a radio transceiver that operates in accordance with another wireless communication protocol (e.g., Bluetooth®). Bluetooth works in the same frequency band as the 802.11 standard and is designed for short-range wireless communication using low power levels.

[0002] Each radio transceiver has its own operating system that controls its operating parameters (eg, state, safety, settings). In particular, these operating systems are independent of each other. For example, if an 802.11 radio transmitter modifies its parameters, the Bluetooth wireless transceiver does not regulate its operations based on the modified parameters of the 802.11 transceiver. Also, the operation of both the receiver and the transmitter in the same frequency band may lead to interference in the broadcast-receiving signal, signal deterioration and / or reduced functionality of each transceiver. For example, performing functions in the 802.11 transceiver may affect or limit the functionality of the Bluetooth transceiver. If so, the user may conclude that it is difficult to manage the transmitting / receiving of signals by the transceivers of the receivers due to interference. [0003] Also problematic in the multiple transceiver and multiprotocol system is that the user is not presented or is not notified of concurrent operations, which may be implemented in transmitter-receivers. In addition, each transceiver may have a separate interface through which the user must coordinate the use of one transceiver while monitoring or controlling the operation of another transceiver. that the user is not presented or is not notified of simultaneous operations that may be carried out in the transmitter-receivers. In addition, each transceiver may have a separate interface through which the user must coordinate the use of one transceiver while monitoring or controlling the operation of another transceiver. that the user is not presented or is not notified of simultaneous operations that may be carried out in the transmitter-receivers. In addition, each transceiver may have a separate interface through which the user must coordinate the use of one transceiver while monitoring or controlling the operation of another transceiver.

[0004] US 2004/0176122 presents IEEE 802.11 transceivers and Bluetooth, which work in a coordinated manner in one telecommunications terminal. The Bluetooth transceiver receives access to a shared communication channel from the IEEE 802.11 transceiver by requiring access.

[0005] US 20002/0061031 describes reducing interference or preventing collisions among multiple wireless WLAN networks.

Summary of the Invention [0006] The invention is in accordance with the appended claims.

[0008] Furthermore, the method of transmitting a signal comprising data from a first radio transceiver to a second radio transceiver determines whether the operation of the second transceiver will interfere with the first radio transceiver based on the data in the signal and regulate the operation of the second radio transceiver as a function of the data .

[0009] Furthermore, the radio transceiver operating in accordance with the first communication protocol includes a receiver for receiving a first signal from another radio transceiver operating in accordance with the second communication protocol, the first signal including operation data of another transceiver, and an operating element. for adjustable operation of the radio transceiver as a function of data.

Detailed Description [0011] Fig. 1 shows an embodiment of a coherent radio system 5 according to the invention. The system 5 may comprise a server 10 connected to the communication network 15. The wired communication network 15 is further connected to the access point ("AP") 20. As may be understood by those skilled in the art, there may be several APs, and the network may comprise any number and types components (eg telephones, faxes, etc.).

[0012] The AP 20 allows the transmission and reception of wireless signals according to the first communication protocol ("FCP") (e.g., 802.11b protocol), using a particular frequency band (e.g., 2.4 GHz band). As one skilled in the art can understand, the AP 20 may include an element (e.g., an antenna) that improves and / or increases the AP 20's ability to send and receive wireless signals.

[0013] The system 5 further comprises a first radio transmitter ("FRT") 25 and a second radio transmitter ("SRT") 30. According to the invention, FRT 25 and SRT 30 may be incorporated into one computer system (e.g. personal computer, laptop, mobile phone, PDA, handheld computer, etc.) or separate computer systems (eg distributed computing environment). FRT 25 and / or SRT 30 may have a corresponding user interface (s). As can be understood by those skilled in the art, the user interface may include, for example, a set of regulators, an operational display, a connector for wired or wireless connection of subsequent devices, antennas, etc.

[0014] The FRT communicates using the first FCP communication protocol, enabling the sending and receiving of signals by the AP 20 and the FCP 35 device (e.g., personal computer, laptop, mobile phone, PDA, handheld computer, etc.) using the first protocol. communication (FCP). As one skilled in the art can understand, an FRT may include an element (e.g., an antenna) (not shown) that improves and / or increases the ability to send and receive wireless signals.

[0015] The SRT 30 may operate in accordance with a second communication protocol ("SCP") (e.g., Bluetooth®) that uses the same frequency band as the FCP. The SRT 30 can communicate with an SCP 40 device that operates using SCP. For example, the SCP device 40 may be a slave device (e.g., a scanner, a printer, a PDA, personal data management devices, a PC card, a headset, etc.). As a slave device, the SCP 40 device can send signals to and receive signals from the SRT 30 using SCP.

[0016] In one embodiment of the invention, the system user 5 may select a particular channel for operating the FRT 25. The FRT 25 may operate in one of several communication channels in the frequency band. As known to those skilled in the art, the frequency band used by the 802.11 network has fourteen channels available for use. However, some countries limit the availability of channels. For example, only channels 1 - 11 are available for use in the United States; on the other hand, channels 1 - 13 are available in most European countries. Only channel 14 is available in Japan. The selected channel will allow communication between devices that operate using FCP (eg FRT 25 and FCP 35). As can be understood by those skilled in the art, the channel selection for the FRT 25 operation may alternatively be made by a program or subroutine.

[0017] After selecting the channel, the FRT 25 sends a signal 45 to SRT 30. The signal 45 may include data for the selected channel. In further embodiments, the data may relate to the operation or intended operation of the FRT 25. For example, the data may disclose operational parameters such as a task being implemented or intended to be performed by the FRT 25, changing the FRT settings and / or changing the FRT state 25. How can they understand those skilled in the art, transmission and reception of signal 45 can be implemented by similar programming interface provided in FRT 25 and SRT 30, using for example the common application interface of the program (common application program interface - "API") or

- 4 alternatively, using a hardware interface such as a common processor when the FRT 25 and SRT 30 are embedded in the same computing system.

After receiving the signal 45, the SRT 30 may regulate its operation using the operating element as a function of the data contained in the signal 45. For example, the SRT 30 may receive channel data that the FRT 25 is currently using or intending to use. The SRT 30, acting in accordance with the SCP, may modify its channel avoidance action that uses or intends to use the FRT 25. In this way, the SRT 30 may regulate its operation in advance before it interferes with FRT operations in the channel.

[0019] Contrary to the prior art, the invention provides a priori knowledge of a channel SRT that is used by FRT 25. A signal 45 from FRT 25 can signal to SRT 30 which channel uses FRT 25. As a result, SRT 30 can modify its bitmask to prevent data transmission in the channel. As a result, SRT 30 does not have to "learn" by having data packets interfering with the channel activity used by the 802.11 device.

[0020] In a further embodiment of the invention, the signal 45 may be transmitted from SRT 30 to FRT 25. For example, the signal 45 may include bit mask data SRT 30. In this way, the FRT 25 can prevent the channels used by the SRT 30 from being selected.

[0021] Fig. 2 shows a further embodiment of a coherent radio system 5. This further embodiment also comprises a server 10 connected to a communication network 15 that is further connected to an AP 20. The AP 20 transmits wireless signals to the FRT 25 and / or SRT 30. The user may select a channel to operate FRT 25. Then, FRT 25 sends signal 45 to SRT 30 with channel selection data. In this embodiment, the SRT 30 may correspond to a further signal 50 that includes data response data included in the signal 45 originally sent by the FRT 25. For example, the SRT 30 may use the channel for an important purpose that can not be interrupted. This next signal 50 to FRT 25 may contain data that inform FRT 25, that the use of a channel by SRT 30 is critical and can not be interrupted or deteriorated in any way. The FRT 25 can then select the next channel based on the data from the next signal 50.

An example of a method 100 according to the invention is shown in Fig. 3. In step 110, FRT 25 transmits a signal 45 to SRT 30. As described above, the signal 45 may include data regarding the operation of FRT 25. In step 120, SRT 30 determines on the basis of the data in signal 45, whether the operation of SRT 30 interferes or will interfere with FRT 25. For example, if the data in signal 45 shows that FRT 25 will use channel two for operation, SRT 30 may want to terminate communication in channel two.

[0023] If the operation of SRT 30 does not interfere with or interfere with FRT 25, then SRT 30 may continue its operation as shown in step 130. However, if SRT 30 interferes with or interferes with FRT 25, the SRT 30 may regulate

- its operation on the basis of data in signal 45 from FRT 25, as shown in step 140. With reference to the example given above, SRT 30 may interrupt communication in channel two. If the SRT 30 uses Bluetooth as SCP, communication interruption in channel two may be accomplished by changing the bit mask SRT 30. For example, entering a zero value into the bit mask may indicate that channel two is "bad" and should not be used (i.e. skipped in AFH).

[0024] Fig. 4 shows a further embodiment of the method 200 according to the invention. In step 210, FRT 25 transmits signal 45 to SRT 30. As described above, signal 45 may include FRT 25 operation data. In step 220, SRT 30 determines whether its performance interferes with or interferes with FRT 25. If SRT 30 does not interfere and will not interfere with the operation of FRT 25, method 200 goes to step 230 where SRT 30 continues its current and / or intended action.

[0025] If SRT 30 determines that its operation interferes with or interferes with the operation of FRT 30, method 200 goes to step 240 where SRT 30 determines whether its current or intended action has priority over FRT 25. As seen in step 250, if the SRT 30 does not take priority over the FRT 25, the SRT 30 regulates its operation on the basis of signal 45 from FRT 25. However, as seen in step 260, if SRT 30 takes precedence over FRT 25 and SRT 30, it transmits next signal 50 to FRT 25, indicates that SRT 30 takes precedence. In step 270, FRT 25 receives the next signal 50 and adjusts its operation on this basis. In this way, the data in the next signal 50 may show that the operation of the SRT 30 is critical and should not be interrupted and / or deteriorated. In response, FRT 25 can prevent actions (e.g.

[0026] According to the invention, signals 45, 50 may include data that respectively depict the operation of FRT 25 and SRT 30. In response to signals 45, 50, FRT 25 or SRT 30 they may decide on their own performance, thereby optimizing the operation of the system. by enabling FRT 25 and SRT 30 to make competent decisions about their operation. However, in a further embodiment, signals 45, 50 may include a command. For example, FRT 25 may perform critical operation. In this way, signal 45 from FRT 25 to SRT 30 includes a command that instructs SRT 30 to stop using channel two. In one example, the SRT 30 must listen to the commands and abandon the channel two until the next instruction by the FRT 25, until a certain time is reached (e.g. meter) or until SRT requests 30 to grant FRT 25 permission to use channel two. In the second example, the FRT 25 may change the operation of the SRT 30 by, for example, blocking SRT access to channel two (e.g., by changing the bit mask SRT 30).

[0027] The system 5 according to the invention can furthermore be used to improve data security. In this way, data transmission that requires the highest security can be given priority over the broadcasting. For example, SRT 30 can be set to "wide-open setting". As can be understood by those skilled in the art, any transmission from SRT 30 is detected by all devices

- 6 in the SRT 30 reception-reception range. Thus, if the FRT 25 performs or intends to perform a safe operation, the signal 45 may include data that represents the SRT 30 that it should improve its safety (e.g., by the "closed to all" setting). "-" closed-to-all ").

[0028] A further embodiment of the system 5 according to the invention is for communication using the voice over internet protocol ("VoIP"). For example, the FRT 25 may use VoIP and thus require uninterrupted or non-aggravated operation to maintain sound quality. Thus, signal 45 from FRT 25 to SRT 30 can inform SRT 30 to prevent connection with a sound profile that could interfere with and impair sound quality if it would have a connection permit.

[0029] A further embodiment of the system 5 is to improve the user experience with FRT 25 and SRT 30. For example, as stated above, each radio transceiver may have its own user interface. If so, the user may be required to adjust the SRT 30 settings after making the FRT 25 changes. However, the system 5 according to the invention allows the automatic adjustment of the SRT 30 after the user has made changes to the FRT 25.

[0030] As may be understood by those skilled in the art, the invention may further be used to provide information on the status of a radio stack, coexistence (e.g., AFH), an error remover console, mesh networks, mobile satellites, wireless local area networks, extensive computer networks and wireless personal networks.

[0031] The invention has been described in connection with radio transmitters 25, 30, FCP communication protocols, SCP and 45, 50 signals. As one skilled in the art can understand, the invention can also be successfully implemented. According to the embodiments, various modifications and variations can be made without departing from the scope of the invention as set forth in the following claims. Accordingly, the description and drawings should be treated as illustrative rather than restrictive.
