Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and a terminal for processing communication interference.
Background
With the rapid development of mobile internet, public places, offices, and home network devices increasingly use WiFi (wireless fidelity) technology to obtain internet services. The wireless terminal can convert the wireless network signal into a WiFi signal and share the WiFi signal to peripheral WiFi equipment. However, the wireless network signal and the WiFi signal may interfere with each other. For example: interference exists between a 2.4G Band (2.4GHz) of WiFi and a Band7 (Band 7 operates at 2.5-2.57GHz) of LTE (Long Term Evolution), and between a 2.3G Band and a 2.5G Band of WiMAX (Worldwide Interoperability for Microwave Access), wherein the 2.4G Band of WiFi is divided into 1-13 channels (only 14 channels are used in japan) as shown in table 1. Specifically, the Band7 of LTE and the 2.5G frequency Band of WiMAX affect the radio frequency indexes of the 10-13 channels of WiFi, so that WiFi cannot work normally when the channels are 10-13; and the 2.3G frequency band of WiMAX will affect the radio frequency index of 1-4 channels of WiFi, resulting in that WiFi can not work normally in 1-4 channels. When wireless network signals and WiFi signals interfere with each other, WiFi cannot work normally, service interruption occurs, and user embodiment is not good. There is thus a need to reduce or avoid interference between wireless network signals and WiFi signals.
The mutual interference between a wireless network and a WiFi frequency band is a problem in the industry all the time, and the current main solution is to reduce the interference by methods such as hardware design, radio frequency parameter and power optimization. The main emphasis on software is that by acquiring the current working frequency band of LTE, changing or switching WiFi working channels (if there is interference), it may cause the current WiFi access client to be disconnected, and user experience is poor.
TABLE 1
The main solutions at present include:
1. frequency division multiplexing scheme: migrating a wireless network working channel to be far away from a WiFi frequency band or migrating the WiFi working channel to be far away from the wireless network frequency band, wherein part of frequency band resources are required to be sacrificed in the scheme;
2. time division multiplexing scheme: based on a DRX (Discontinuous Reception) scheme, HARQ (Hybrid Automatic Repeat reQuest) processing and uplink scheduling restriction are adopted. This scheme requires sacrificing part of the traffic rate performance.
3. The power control scheme comprises the following steps: primarily by limiting the power of the wireless network and WiFi network. This scheme requires sacrificing traffic coverage performance.
4. The terminal automatic processing scheme comprises the following steps: the method mainly comprises the steps of automatically closing a WiFi interference channel for protecting the wireless network frequency band, and automatically closing the wireless network frequency band for protecting the WiFi frequency band. The current solution of the scheme is to judge whether the current access frequency band of the wireless wide area network and the working channel of the WiFi wireless local area network have interference or not after acquiring the current working frequency band of the wireless network, and if so, the WiFi working channel is switched. The method has the problems that if the client is accessed at the current WiFi side, the client accessed at the current WiFi side is disconnected if the WiFi working channel is switched, and the user embodiment is poor. The other solution is that according to the customization requirements of different operators, mutual interference is reduced by directly shielding WiFi partial channels interfering with the wireless network, and the solution has poor universality and cannot solve the mutual interference problem between the wireless network accessing different frequency bands and the WiFi.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
Fig. 1 is a flowchart of a method for processing communication interference according to a first embodiment of the present invention, as shown in fig. 1, the method of the present embodiment includes:
and step 12, selecting and setting a WiFi working channel from the non-interference channels of the current WiFi.
According to the embodiment of the invention, when a terminal is networked according to preset configuration information, the preset configuration information is inquired by acquiring the access frequency band of the current wireless wide area network, the non-interference working channel range of WiFi is acquired, and then the WiFi is set to work in a non-interference working channel; when the terminal is not networked, the operator information corresponding to the SIM is acquired, the preset configuration information is inquired, the access frequency band distributed by the operator corresponding to the SIM is acquired, the corresponding WiFi non-interference working channel range is acquired, and then the WiFi is set to work in a non-interference working channel.
In the method of this embodiment, when the terminal operates in different wireless frequency bands according to the wireless network, the WiFi automatically selects and operates in a non-interfering operating channel, and it can be found that the operating channel ranges of the WiFi are different when the terminal uses different SIM cards (registers wireless networks of different frequency bands or wireless operators belonging to different frequency bands) in networking and non-networking.
Fig. 2 is a flowchart of a communication interference processing method according to a second embodiment of the present invention, as shown in fig. 2, the method includes:
step 101: after the terminal is started, obtaining SIM card information;
further, the terminal obtains MCC (Mobile Country Code) and MNC (Mobile Network Code) information of the SIM card by reading the SIM card.
The MCC resources are uniformly distributed and managed by the International Telecommunication Union (ITU), the country to which the mobile subscriber belongs is uniquely identified, 3 countries are in total, and the number of the countries is 460;
the MNC is used for identifying the mobile network to which the mobile client belongs. The MNC is composed of two to three decimal numbers, for example, MNC of china mobile is 00, 02 and 07, MNC of china unicom is 01, 06, 09, MNC of china telecom is 03. MNCs are generally uniformly distributed by the relevant telecommunications administration of a country, and one operator may own one or more MNCs (depending on the scale of service provision), but different operators may not share the same MNC. Due to the special meaning of MNC, it is not allowed to change once it is set in the network.
Step 102: the terminal registers and connects to the wireless network according to the SIM card information;
further, the wireless network refers to a wireless wide area network, such as a 3G/LTE network.
Step 103: the terminal judges whether the wireless network is successfully connected, if so, the step 104 is executed, and if not, the step 106 is executed.
Step 104: the terminal acquires the access frequency band of the current wireless network.
Step 105: the terminal queries the non-interference working channel range of WiFi through the MCC and MNC information of the current SIM card according to preset configuration information, and then executes step 107;
further, the access frequency band of the device after connecting to the wireless network can be obtained in advance through the MCC and the MNC. Since the international Telecommunication union Telecommunication Standardization organization (ITU-T for ITU Telecommunication Standardization Sector) has promoted that each country customizes Telecommunication operating frequency bands of different operators, as shown in table 2, WiFi interference channels corresponding to a part of radio frequency bands allocated by each operator in china.
TABLE 2
Step 106: the terminal queries the non-interference working channel range of the WiFi through the current wireless access frequency band according to the preset configuration information, and executes step 107.
Further, the access frequency Band of the wireless wide area network may be, for example, Band7 of LTE, 2.3G frequency Band and 2.5G frequency Band of WiMAX. The 2.5G frequency bands of both the Band7 of LTE and WiMAX have interference with CH10-CH13 channels of WiFi; interference exists between the 2.3G frequency band of WiMAX and the CH1-CH4 channel of WiFi; the 2.5G frequency bands of both the Band7 of LTE and WiMAX have no interference with the CH1-CH9 channels of WiFi; the 2.3G frequency band of WiMAX does not interfere with the CH5-CH13 channel of WiFi.
Step 107: the terminal selects and sets a WiFi operating channel within the range of the non-interference operating channel of the current WiFi.
Furthermore, the embodiment of the invention does not limit the channel range and the division mode of the WiFi wireless local area network. In particular embodiments, how to adjust the operating channel may be determined according to the WiFi channel range of the actual application. For example: if the actually applied WiFi channel range is 1-13, the working channel can be adjusted to any one of 5-13 channels in order to avoid interference with the 2.3G frequency band of WiMAX; if the WiFi channel range in practical application is 1-14, the working channel may be adjusted to any one of 5-14 channels in order to avoid interference with the 2.3G frequency band of WiMAX.
Further, when the working channel is adjusted to any one of the 5-13 channels, the working channel may be randomly selected, or may be selected according to a certain rule, for example, the working channel may be realized by a WiFi module according to a channel automatic selection algorithm of each chip manufacturer, and an optimal channel is preferentially selected.
