Embodiment 1

[0037] 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.

[0038] 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.

[0039] 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 ...

Embodiment 2

[0045] The present invention will be described below from the perspective of coexistence modules.

[0046]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 mul...

Embodiment 3

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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, the WiFi broadcast channel conflicts with the WiMAX channel, and informs the WiMAX device through the internal interface, WiMAX The device send...

Abstract

The invention discloses a method, a device and a system for eliminating channel confliction between multimode terminal systems. The embodiment of the invention learns the time when a WiFi broadcast channel and a WiMAW channel generate confliction, adjusts the transmission of the WiFi broadcast channel or the WiMAW channel according to the time when the confliction is generated, avoids the confliction of the WiFi broadcast channel and the WiMAW channel generated at the time when the confliction is generated, thereby solving the problem that interference is generated to the WiMAW channel when WiFi equipment transmits WiFi broadcast messages through the WiFi broadcast channel, and ensuring normal communication of the multimode terminal.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, device and system for eliminating channel conflicts between multi-mode terminal systems. Background technique [0002] With the continuous development of World Interoperability for Microwave Access (WiMAX: World Interoperability for Microwave Access) technology and Wireless Fidelity (WiFi: Wireless Fidelity) technology, it is becoming more and more difficult to realize the coexistence of WiMAX devices and WiFi devices in a multi-mode terminal. However, there is interference between WiMAX technology and WiFi technology, which will inevitably affect the normal communication of multi-mode terminals. One of the most important problems to be solved when multi-mode terminals coexist. [0003] In order to realize the coexistence of the WiMAX device and the WiFi device, the existing technology adopts the sleep mode of the WiMAX device to realize the coexistence of the W...
