detailed description

The embodiment of the invention discloses a channel selection method and a terminal, which are used for improving the sensitivity and throughput of a WIFI hotspot. rate. The details are described below.

In order to better understand a channel selection method and terminal disclosed in the embodiments of the present invention, the basic concepts used in the embodiments of the present invention are described below. The factors affecting the WIFI signal of the LTE network include: the isolation of the LTE/WIFI antenna, the working frequency of the LTE, the working bandwidth of the LTE, the signal transmission power of the LTE, the LTE band filter, the astray power of the LTE transmitter, and the signal strength of the WIFI. And the working mode of WIFI. Among them, the isolation of LTE/WIFI antenna, LTE band filter and LTE transmitter spurious power are determined by LTE and WIFI fusion terminal products, which are inherent attributes of products, which are fixed for one terminal. The operating frequency, working bandwidth, and signal transmission power of LTE are determined by the LTE cell where the terminal resides, and vary with the change of the LTE cell where the terminal resides, in the 3rd Generation Partnership Project (3GPP). The protocol specifies that the working frequency and working bandwidth of LTE are completely determined by the base station (BS) in LTE, and the signal transmission power of LTE can be adjusted within the allowable range. The signal strength of the WIFI is determined by the communication distance of the WIFI hotspot, that is, determined by the terminal that establishes the WIFI hotspot and the corresponding station (station, STA). The working mode of WIFI is determined by the quality of the communication signal of the WIFI hotspot, and can be adjusted according to the requirements of Quality of Service (QoS).

Evaluating the interference of the LTE network to the WIFI signal can be performed by the combination of various variable parameters of the LTE network on the sensitivity of the various WIFI operating modes and the interference rate of the throughput. Among them, the influence of the sensitivity of the WiFi can be determined by comparing the absolute value of the sensitivity in the case of LTE network interference with the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard by 5 dB, for example, WIFI without interference. The sensitivity of the channel is 80dB, and when the sensitivity of the WIFI channel is 75dB when there is interference, it indicates that the interference of the LTE network is 5dB. The impact of the throughput rate of WiFi can be determined by reducing the relative value of the throughput rate by 10% in the case of LTE network interference. For example, the throughput of the WIFI channel is 5 Mbps when there is no interference, and the throughput rate of the WIFI channel is 4.5 Mbps when there is interference. , indicating that the relative value of the interference of the LTE network to the throughput rate is reduced by 10%.

Table 1 is an evaluation example of a variable parameter combination, the first behavior is an LTE variable parameter, and the first column is a WIFI variable parameter. Table 1 shows an example in which the WIFI working channel of the terminal is CH1, the WIFI working mode is 802.11b 1 Mbps, and the WIFI signal strength is -50 dBm. The LTE variable parameter in the first line is given in the form of a range, but the interference to the throughput and sensitivity of the WIFI channel may be given by a specific value, or may be a small range. Given, it can also be given in a wide range, for example, it can be given in band 40: 2300 ~ 2400MHz, 2300 ~ 2310MHz, or 2330MHz. Wherein, when the combination of the WIFI variable parameters is unchanged, and the combination of the LTE variable parameters changes, the interference of the LTE network on the throughput and sensitivity of the WIFI channel will change; when the combination of the WIFI variable parameters changes, and When the combination of LTE variable parameters does not change, the interference of the LTE network on the throughput and sensitivity of the WIFI channel will change. The WIFI working channel of the terminal may include CH1-CH14, and the WIFI working mode of the terminal may include 802.11b 1Mbps, 802.11b 2Mbps, 802.11b 5.5Mbps, 802.11b 11Mbps, 802.11g 6Mbps, 802.11g 9Mbps, 802.11g 12Mbps, 802.11. g 18Mbps, 802.11g 24Mbps, 802.11g 36Mbps, 802.11g 48Mbps, 802.11g 54Mbps, 802.11n MCS0, 802.11n MCS1, 802.11n MCS2, 802.11n MCS3, 802.11n MCS4, 802.11n MCS5, 802.11n MCS6, 802.11n MCS7 The WIFI signal strength of the terminal may include -50 to -80 dBm or other signal strength ranges. Therefore, the interference of the LTE network to the WIFI channel may be collected in advance and stored in the terminal. After the terminal establishes the WIFI hotspot, when the WIFI channel is selected, the interference of the stored WIFI channel may be invoked to perform channel selection.
