Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

An embodiment of the present invention provides a method for eliminating channel conflicts between multi-mode terminal systems. Embodiments of the present invention also provide corresponding devices and systems. Each will be described in detail below.

Embodiment one,

The present invention will be described below from the perspective of a multi-mode terminal, wherein the WiFi device and WiMAX are located in the multi-mode terminal.

A method for eliminating channel conflicts between multi-mode terminal systems. First, the multi-mode terminal knows the time when the WiFi broadcast channel conflicts with the WiMAX channel. For example, it can calculate the superframe number at which the WiFi broadcast channel conflicts with the WiMAX channel. The transmission of the WiFi broadcast channel and the WiMAX channel is adjusted according to the time when the conflict occurs.

Wherein, the WiMAX channel refers to the WiMAX synchronization channel and the broadcast channel, and the WiMAX synchronization channel and the broadcast channel are located in the same subframe (subframe), that is, in the first subframe of each superframe, the WiMAX base station (BS: Base Station) will send the preamble and the broadcast message to the WIMAX device through the synchronization channel and the broadcast channel respectively at the fixed position of each superframe, wherein, a superframe is composed of 4 frames, and a frame is composed of 8 subframes, and the frame duration is, That is, the frame length is 5ms. The WiFi device will periodically transmit WiFi broadcast messages, such as sending a WiFi beacon (Beacon) for synchronization in the WiFi management frame. The transmission cycle of the WiFi Beacon is generally 100 time units (TU: TimeUnit). That is 102.4ms.

As shown in Figure 1, the specific process of this embodiment is as follows:

101. The multimode terminal learns the time when the WiFi broadcast channel conflicts with the WiMAX channel;

102. The multimode terminal adjusts the transmission of the WiFi broadcast channel or the WiMAX channel according to the time when the conflict occurs, so as to avoid the conflict between the WiFi broadcast channel and the WiMAX channel.

As can be seen from the above, in this embodiment, by knowing the time when the WiFi broadcast channel and the WiMAX channel conflict, and then adjusting the transmission of the WiFi broadcast channel or the WiMAX channel according to the time of the conflict, avoiding the conflict between the WiFi broadcast channel and the WiMAX channel Time conflicts occur, thereby solving the problem of interference to the WiMAX channel when the WiFi device transmits WiFi broadcast information through the WiFi broadcast channel, and ensuring the normal communication of the multi-mode terminal.

Embodiment two,

The present invention will be described below from the perspective of coexistence modules.

A method for eliminating channel conflicts between multi-mode terminal systems. First, the coexistence module learns the sending time of the WiFi broadcast message transmitted through the WiFi broadcast channel, and then obtains the generation time between the WiFi broadcast channel and the WiMAX channel according to the learned sending time of the WiFi broadcast message. The time of conflict, such as calculating the superframe number at which the WiFi broadcast channel and the WiMAX channel will conflict, and finally inform the multi-mode terminal of the conflict time in a certain way, so that the multi-mode terminal can adjust according to the conflict time The transmission of the WiFi broadcast channel and the WiMAX channel avoids the conflict between the WiFi broadcast channel and the WiMAX channel at the time when the conflict should occur. The WiMAX device in the multimode terminal will not send information through the WiMAX channel, or let the WiMAX device in the multimode terminal sleep, that is, neither receive nor send information, or let the WiFi device in the multimode terminal not send WiFi broadcast messages, Or adjust the time when the WiFi device sends a WiFi broadcast message, or the WiFi device in the multi-mode terminal goes to sleep, etc. It should be noted that the WiFi device can be a WiFi base station (AP) or a WiFi terminal (AT). When the WiFi device is a WiFi base station, it is possible to change the time for the WiFi device to send the WiFi broadcast message through the WiFi broadcast channel before the conflict occurs, or to allow the WiFi device not to send the WiFi broadcast message through the WiFi broadcast channel at the time when the conflict occurs; When the WiFi device is a WiFi terminal, the WiFi device can be allowed to sleep at the time when the conflict occurs.

Wherein, the coexistence module can be placed in the multimode terminal or in the WiMAX base station.

As shown in Figure 2, the specific process of this embodiment can be as follows:

201. Obtain the sending time of the WiFi broadcast information transmitted through the WiFi broadcast channel;

202. Know the time when the WiFi broadcast channel conflicts with the WiMAX channel according to the sending time;

203. Notify the multimode terminal of the time when the conflict occurs, so as to avoid the conflict between the WiFi broadcast channel and the WiMAX channel.

It can be seen from the above that the coexistence module of this embodiment can obtain the time when the WiFi broadcast channel conflicts with the WiMAX channel by knowing the sending time of the WiFi broadcast information transmitted through the WiFi broadcast channel, and inform the multi-mode terminal, so that the multi-mode terminal can adjust the transmission of the WiFi broadcast channel or WiMAX channel according to the time of the conflict, avoiding the conflict between the WiFi broadcast channel and the WiMAX channel at the time of the conflict, thereby solving the problem of WiFi devices transmitting through the WiFi broadcast channel The problem of interference to WiMAX channels when WiFi broadcasts information ensures the normal communication of multi-mode terminals.

Embodiment three,

According to the methods described in the above embodiments, the following will take sending a WiFi Beacon through a WiFi broadcast channel as an example for further detailed description.

In this embodiment, the present invention is mainly described by taking the case where the coexistence module is located inside the multi-mode terminal as an example.

Assume that the first WiFi Beacon after the multi-mode terminal enters coexistence is sent at the 0th superframe, the mth frame, and the nth downlink subframe of the WiMAX channel, where m and n are both integers, and m=1～ 4, n=1-8.

First of all, the coexistence module needs to obtain the sending time of the WiFi Beacon, and then according to the sending time, it knows that the WiFi Beacon will interfere with the WiMAX channel in a certain superframe, that is, the WiFi broadcast channel conflicts with the WiMAX channel, and informs the WiMAX device through the internal interface, WiMAX The device sends a request message to the WiMAX base station, requesting to sleep at the conflicting superframe, and finally the WiMAX device accepts the instruction sent by the WiMAX base station about allowing the WiMAX device to sleep at the conflicting superframe, that is, receives the permission from the WiMAX base station After the message that the WiMAX device sleeps at the conflicted superframe, the WiMAX device sleeps at the conflicted superframe.

As shown in Figure 3, the concrete steps of this embodiment can be as follows:

301. The coexistence module in the multi-mode terminal obtains the sending time of the WiFi Beacon, that is, the WiFi Beacon is sent at the time of the superframe, the mth frame, and the nth downlink subframe of the WiMAX channel;

302. The coexistence module in the multimode terminal calculates the superframe number at which the WiFi Beacon interferes with the WiMAX channel according to the acquired transmission time of the WiFi Beacon, that is, the superframe number at which the WiFi broadcast channel conflicts with the WiMAX channel; the calculation method can be as follows :

Conflicting superframe number = rounding (WiFi Beacon transmission period * integer - (4-m+1) * frame length + subframe length * (n-1)) / superframe length, simplified as:

Conflicted superframe number = rounded (WiFi Beacon transmission period * integer - (5-m) * frame length + subframe length * (n-1)) / superframe length, where m is any of 1 to 4 An integer, n is any integer from 1 to 8.

Alternatively, the following algorithm can be used:

Conflicting superframe number = rounding (WiFi Beacon transmission period * integer - (4-m) * frame length + subframe length * (8-n+1)) / superframe length, simplified as:

Conflicted superframe number = rounded (WiFi Beacon transmission period * integer - (4-m) * frame length + subframe length * (9-n)) / superframe length, where m is any of 1 to 4 An integer, n is any integer from 1 to 8.

303. The coexistence module in the multimode terminal notifies the WiMAX device in the multimode terminal through the internal interface of the superframe number calculated in step 302 before the conflict occurs;

304. The WiMAX device in the multimode terminal sends a request message to the WiMAX base station, requesting to sleep at the superframe corresponding to the superframe number, that is, the conflicting superframe;

305. The WiMAX base station notifies the WiMAX device through a message, allowing the WiMAX device to sleep at the conflicting superframe;

306. The WiMAX device sleeps at the conflicting superframe according to the instruction of the WiMAX base station, so as to avoid conflicting with the WiFi broadcast channel.

As can be seen from the above, the coexistence module in the multimode terminal of this embodiment can obtain the superframe number of the conflict between the WiFi broadcast channel and the WiMAX channel by knowing the transmission time of the WiFi Beacon, and notify the superframe number to the user through the internal interface. For the WiMAX device in the multimode terminal, in order to avoid conflicts, the multimode terminal allows the WiMAX device to sleep at the superframe corresponding to the superframe number, thereby solving the problem of WiMAX channel interference caused by the WiFi Beacon sent by the WiFi device, and ensuring that the multimode Normal communication of the terminal.

Embodiment four,

Different from the third embodiment, the coexistence module of this embodiment is not located in the multimode terminal, but located in the WiMAX base station.

Assume that the first WiFi Beacon after the multi-mode terminal enters coexistence is sent at the 0th superframe, the mth frame, and the nth downlink subframe of the WiMAX channel, where m is any integer from 1 to 4, and n Any integer from 1 to 8.

First, the coexistence module needs to obtain the sending time of the WiFi Beacon, and then learn that the WiFi Beacon will interfere with the WiMAX channel in a certain superframe according to the sending time, that is, obtain the superframe number where the WiFi broadcast channel conflicts with the WiMAX channel, and generate information about The message of the superframe number sends the message about the superframe number to the WiMAX device in the multimode terminal through the WiMAX base station, and instructs the WiMAX device to sleep at the superframe corresponding to the superframe number, and the WiMAX After receiving the indication, the device sleeps at the superframe corresponding to the superframe number, that is, the conflicting superframe, so as to avoid conflict with the WiFi Beacon sent by the WiFi device.

As shown in Figure 4, the concrete steps of this embodiment can be as follows:

401. The coexistence module in the WiMAX base station obtains the sending time of the WiFi Beacon, that is, the WiFi Beacon is sent at the time of the superframe, the mth frame, and the nth downlink subframe of the WiMAX channel;

402. The coexistence module in the WiMAX base station calculates the superframe number at which the WiFi Beacon interferes with the WiMAX channel according to the acquired transmission time of the WiFi Beacon, that is, the superframe number at which the WiFi broadcast channel conflicts with the WiMAX channel; the calculation method can be found in the implementation Step 302 in Example 3 is not redundant here.

403. The coexistence module in the WiMAX base station generates a message about the superframe number;

404. The WiMAX base station sends the message about the superframe number to the WiMAX device in the multimode terminal, and instructs it to sleep at the superframe corresponding to the superframe number;

405. The WiMAX device sleeps at the superframe corresponding to the superframe number according to the instruction sent by the WiMAX base station, so as to avoid conflict with the WiFi broadcast channel.

It can be seen from the above that in order to save the signaling traffic between the WiMAX equipment and the WiMAX base station, the coexistence module can be placed in the WiMAX base station. In this way, after the WiMAX base station knows the superframe number of the conflict between the WiFi broadcast channel and the WiMAX channel, it can The WiMAX device can be notified directly through a message to sleep at the superframe where the conflict occurs, without sending a request message by the WiMAX device. Moreover, the coexistence module in this solution can also obtain the superframe number of the conflict between the WiFi broadcast channel and the WiMAX channel by knowing the sending time of the WiFi Beacon. Normal communication of the terminal.

Whether to place the coexistence module in the multimode terminal or in the WiMAX base station can be determined according to the operator's strategy.

In addition, in the third and fourth embodiments, in addition to allowing the WiMAX device in the multimode terminal to sleep at the time when the conflict occurs, similarly, the WiMAX device in the multimode terminal can also be allowed to sleep at the time when the conflict occurs The information is not transmitted through the WiMAX channel, that is, the WiMAX device does not send information through the WiMAX channel, or does not receive information sent by the WiMAX base station through the WiMAX channel.

Embodiment five,

Similar to Embodiment 3, the coexistence module in this embodiment is also placed in the multi-mode terminal; different from Embodiments 3 and 4, this embodiment avoids the interference of WiFi broadcast channel and WiMAX by controlling the transmission of WiFi Beacon. If the channel conflicts, for example, at the superframe where the WiFi broadcast channel conflicts with the WiMAX channel, the WiFi device does not send a WiFi Beacon; for another example, the time for the WiFi device to send a WiFi Beacon can be changed to avoid conflicts and so on.

The following will take the WiFi device not to send WiFi Beacon at the superframe where the WiFi broadcast channel conflicts with the WiMAX channel as an example.

Assume that the first WiFi Beacon after the multi-mode terminal enters coexistence is sent at the 0th superframe, the mth frame, and the nth downlink subframe of the WiMAX channel, where m is any integer from 1 to 4, and n Any integer from 1 to 8.

First, the coexistence module needs to obtain the sending time of the WiFi Beacon, and then according to the sending time, it knows that the WiFi Beacon will interfere with the WiMAX channel in a certain superframe, that is, it knows the superframe number of the conflict between the WiFi broadcast channel and the WiMAX channel, and through the internal The interface informs the WiFi device that the WiFi device is required not to send a WiFi Beacon at the conflicting superframe, and finally, the WiFi device does not send a WiFi Beacon at the conflicting superframe.

As shown in Figure 5, the specific steps of this embodiment can be as follows:

501. The coexistence module in the multi-mode terminal obtains the sending time of the WiFi Beacon, that is, the WiFi Beacon is sent at the time of the superframe, the mth frame, and the nth downlink subframe of the WiMAX channel;

502. The coexistence module in the multimode terminal calculates the superframe number at which the WiFi broadcast channel conflicts with the WiMAX channel according to the acquired transmission time of the WiFi Beacon. For the calculation method, refer to step 302 in Embodiment 3, which is not repeated here.

503. The coexistence module in the multi-mode terminal notifies the WiFi device in the multi-mode terminal of the superframe number calculated in step 502 through the internal interface before the conflict occurs, and requires the WiFi device not to send a WiFi Beacon at the conflicting superframe ;

504. The WiFi device does not send the WiFi Beacon at the conflicting superframe, that is, goes to sleep, so as to avoid conflict with the WiMAX channel.

As can be seen from the above, the coexistence module in the multimode terminal of this embodiment can obtain the superframe number of the conflict between the WiFi broadcast channel and the WiMAX channel by knowing the transmission time of the WiFi Beacon, and notify the superframe number to the user through the internal interface. For the WiFi devices in the multi-mode terminal, in order to avoid conflicts, the multi-mode terminal allows the WiFi device not to send WiFi Beacon at the superframe corresponding to the superframe number, thus solving the problem that the WiFi device sending WiFi Beacon interferes with the WiMAX channel, ensuring Normal communication of multimode terminals. Compared with Embodiments 3 and 4, this embodiment does not need to negotiate with the WiMAX base station, that is, it can save signaling traffic with the WiMAX base station.

Embodiment six,

Similar to Embodiment 5, this embodiment also avoids the conflict between the WiFi broadcast channel and the WiMAX channel by controlling the transmission of the WiFi Beacon. For example, at the superframe where the WiFi broadcast channel and the WiMAX channel conflict, the WiFi device does not send the WiFi Beacon ; Another example, you can change the time when the WiFi device sends the WiFi Beacon, so as to avoid conflicts and so on. However, the coexistence module in this embodiment is located in the WiMAX base station instead of the multi-mode terminal.

The following will take the WiFi device to change the WiFi Beacon at the superframe where the WiFi Beacon conflicts with the WiMAX channel as an example.

Assume that the first WiFi Beacon after the multi-mode terminal enters coexistence is sent at the 0th superframe, the mth frame, and the nth downlink subframe of the WiMAX channel, where m is any integer from 1 to 4, and n Any integer from 1 to 8.

First, the coexistence module needs to obtain the sending time of the WiFi Beacon, and then according to the sending time, learn the superframe number of the conflict between the WiFi Beacon and the WiMAX channel, and generate a message about the superframe number. The message of the frame number is sent to the WiMAX device in the multimode terminal. After receiving the message, the WiMAX device notifies the WiFi device through the internal interface. The WiFi device appropriately changes the time to send the WiFi Beacon according to the current service to avoid the communication with the WiMAX channel. conflict.

As shown in Figure 6, the specific steps of this embodiment can be as follows:

601. The coexistence module in the WiMAX base station obtains the sending time of the WiFi Beacon, that is, the WiFi Beacon is sent at the time of the superframe, the mth frame, and the nth downlink subframe of the WiMAX channel;

602. The coexistence module in the WiMAX base station calculates the superframe number at which the WiFi broadcast channel conflicts with the WiMAX channel according to the acquired transmission time of the WiFi Beacon. The calculation method can refer to step 302 in Embodiment 3, and it is not redundant here.

603. The coexistence module in the WiMAX base station generates a message about the superframe number;

604. The WiMAX base station sends the message about the superframe number to the WiMAX device in the multimode terminal;

605. The WiMAX device notifies the WiFi device of the message about the superframe number through an internal interface;

606. After receiving the message about the superframe number, the WiFi device appropriately changes the time for sending the WiFi Beacon according to the current service, so as to avoid conflict with the WiMAX channel.

After this time, the coexistence module in the WiMAX base station can recalculate the superframe number of the conflict between the WiFi Beacon and the WiMAX channel.

As can be seen from the above, the coexistence module in the WiMAX base station of this embodiment can obtain the superframe number of the conflict between the WiFi broadcast channel and the WiMAX channel by knowing the transmission time of the WiFiBeacon, and notify the superframe number to the multimode through the WiMAX base station The terminal makes the WiFi device in the multi-mode terminal change the time of sending WiFi Beacon, thereby avoiding the conflict between the WiFi broadcast channel and the WiMAX channel, solving the problem that the WiFi device sending WiFi Beacon interferes with the WiMAX channel, and ensuring the normal operation of the multi-mode terminal communication.

Certainly, compared with the fifth embodiment, this embodiment needs to negotiate with the WiMAX base station, that is to say, the signaling traffic with the WiMAX base station is increased, so the fifth embodiment is better than the sixth embodiment. Whether to place the coexistence module in the multimode terminal or in the WiMAX base station can be determined according to the operator's strategy.

In addition, it is explained that in Embodiment 5 and Embodiment 6, except at the time when the conflict occurs, the WiFi device is not allowed to send WiFi broadcast messages through the WiFi broadcast channel, or the WiFi device is adjusted to send WiFi broadcast messages through the WiFi broadcast channel In addition to the time of the message, when the WiFi device is a WiFi terminal, the WiFi device can also be made to sleep. Since the implementation scheme is similar, it is not redundant here.

Embodiment seven,

In order to better implement the above method, the present invention also provides a multi-mode terminal correspondingly, as shown in FIG. 7 , including an acquisition unit 701 and an adjustment unit 702; Can be located in a WiMAX base station.

The obtaining unit 701 is configured to obtain the time when the WiFi broadcast channel conflicts with the WiMAX channel;

For example, when the coexistence module is located in the multi-mode terminal, it can know the time when the WiFi broadcast channel conflicts with the WiMAX channel through the internal interface; when the coexistence module is located in the WiMAX base station, it can receive information about the WiFi broadcast channel and WiMAX The time when the channel conflicts occurs to know the time when the WiFi broadcast channel conflicts with the WiMAX channel and so on. The so-called time of knowing that the WiFi broadcast channel conflicts with the WiMAX channel may be the acquisition of the superframe number at which the WiFi broadcast channel conflicts with the WiMAX channel.

The adjustment unit 702 is configured to adjust the transmission of the WiFi broadcast channel or the WiMAX channel according to the time when the conflict occurs acquired by the acquisition unit 701;

For example, if the coexistence module is located in the WiMAX base station, the adjustment unit 702 can directly accept the instruction sent by the WiMAX base station about allowing the WiMAX device in the multi-mode terminal to sleep at the time when the conflict occurs, so that the WiMAX device can be in sleep at the time when the conflict occurs. Dormancy at the time when the conflict occurs at the time of the conflict, or allow the WiMAX device not to transmit information through the WiMAX channel at the time of the conflict; or

The WiFi device in the multi-mode terminal can be allowed to sleep at the time when the conflict occurs, or the WiFi device can not send WiFi broadcast information through the WiFi broadcast channel at the time when the conflict occurs. Before changing the time for WiFi devices to send WiFi broadcast information through the WiFi broadcast channel, etc. Of course, letting the WiFi device sleep at the conflicting time mentioned here refers to when the WiFi device is a WiFi device other than a WiFi base station, such as a WiFi terminal.

Wherein, when the coexistence module is located in the multimode terminal, the adjustment unit 702 may also include:

The sending unit 7021 is configured to send a request message to the WiMAX base station, the request message requests the WiMAX base station to allow the WiMAX device to sleep at the time of the conflict obtained by the obtaining unit 701;

The processing unit 7022 is configured to accept an instruction sent by the WiMAX base station about allowing the WiMAX device to sleep at the time when the conflict occurs, the instruction is made by the WiMAX base station according to the request message sent by the sending unit 7021 .

It can be seen from the above that the multimode terminal in the embodiment of the present invention can adjust the transmission of the WiFi broadcast channel or the WiMAX channel according to the time when the conflict occurs by knowing the superframe number of the conflict between the WiFi broadcast channel and the WiMAX channel, so as to avoid the WiFi broadcast channel The conflict occurs with the WiMAX channel at the time when the conflict occurs, thereby solving the problem of interference to the WiMAX channel caused by the WiFi broadcast message sent by the WiFi device, and ensuring the normal communication of the multi-mode terminal.

The second acquiring unit 802 is configured to know the time when the WiFi broadcast channel conflicts with the WiMAX channel according to the transmission time acquired by the first acquiring unit 801;

The notification unit 803 is configured to notify the multimode terminal of the time when the conflict is learned by the second acquisition unit 802 to adjust the transmission of the WiFi broadcast channel or the WiMAX channel;

For example, when the coexistence module is located in the multi-mode terminal, the notification unit 803 can notify the WiMAX device or WiFi device in the multi-mode terminal of the conflicting time learned by the second acquisition unit 802 through the internal interface, so as to adjust the WiFi broadcast channel or the WiMAX channel transmission.

Wherein, when the coexistence module is located in the WiMAX base station, the notification unit 803 may also include:

a message generating unit 8031, configured to generate a message about the time of conflict obtained by the second obtaining unit 802;

The sending unit 8032 is configured to send the message about the time of the conflict generated by the message generating unit 8031 to the multimode terminal through the WiMAX base station, so as to adjust the transmission of the WiFi broadcast channel or the WiMAX channel.

The coexistence module of the present invention can know the sending time of the WiFi broadcast message transmitted through the WiFi broadcast channel, and then calculate the time when the WiFi broadcast channel conflicts with the WiMAX channel according to the sending time, and inform the multimode terminal of the conflicting time , so that the multi-mode terminal can adjust the transmission of the WiFi broadcast channel or the WiMAX channel according to the time when the conflict occurs, avoiding the conflict between the WiFi broadcast channel and the WiMAX channel at the time when the conflict occurs, thereby solving the problem of WiMAX when the WiFi device sends a WiFi broadcast message The problem of channel interference is guaranteed to ensure the normal communication of multi-mode terminals.

Embodiment nine,

In order to better implement the above method, the present invention also correspondingly provides a communication system, as shown in FIG. 9 , including a coexistence module 901 and a multi-mode terminal 902;

The coexistence module 901 is configured to know the sending time of the WiFi broadcast message, know the time when the WiFi broadcast channel conflicts with the WiMAX channel according to the obtained sending time, and notify the multimode terminal 902 of the learned time when the conflict occurs, the WiFi broadcast message Messages are sent over the WiFi broadcast channel;

The multimode terminal 902 is configured to learn from the coexistence module 901 the time when the WiFi broadcast channel conflicts with the WiMAX channel, and then adjust the transmission of the WiFi broadcast channel and the WiMAX channel according to the acquired conflict time.
