Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a wireless access method, apparatus and terminal equipment. Background Technology

[0002] When a user connects to the network using a terminal device, if the terminal device is simultaneously connected to both a Wireless Fidelity (WiFi) network and a cellular network, the terminal device will select the appropriate network for transmission based on the service the user is using (including but not limited to voice, data, and video).

[0003] If the frequency used to access a WiFi network is close to the frequency used to access a cellular network, interference may occur between the two networks, potentially damaging hardware or degrading service quality in the terminal device. In related technologies, when a terminal device accesses a WiFi network, it randomly selects one from a pool of available frequencies. If the cellular connection is active, there may be scenarios where the WiFi access point's frequency and the cellular network's frequency are very close, causing interference and reducing the reliability of the terminal's hardware, potentially damaging it and impacting the user experience.

[0081] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0082] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0083] To facilitate understanding, the following will be combined with... Figure 1 The application scenarios applicable to the embodiments of this application will be described.

[0084] Figure 1 This is a schematic diagram illustrating an application scenario provided in an embodiment of this application. Please refer to [link / reference]. Figure 1 The system includes a terminal device 101, a base station 102, and a WiFi access point 103. The terminal device 101 can be a mobile phone, tablet computer, etc. The terminal device 101 contains a smart chip. The terminal device 101 can access a cellular network via the base station 102, and it can also access a WiFi network via the WiFi access point 103. When the terminal device 101 accesses the network, its smart chip can determine the frequency for accessing the cellular network and the WiFi network.

[0085] In related technologies, when a terminal device accesses a WiFi network, it randomly selects an access frequency from the candidate access frequencies as the access frequency of the WiFi access point. If the cellular network is in a connected state, there may be a situation where the access frequency of the WiFi access point and the access frequency of the cellular network are very close, resulting in interference between the WiFi network and the cellular network.

[0086] In this embodiment, when a terminal device accesses a network, it determines the WiFi access point to be connected and at least one candidate access frequency for that WiFi access point. It also obtains the cellular wireless connection status of the terminal device. Based on the cellular wireless connection status, it determines the target WiFi frequency of the WiFi access point from at least one candidate access frequency. In this process, because the target WiFi frequency of the WiFi access point can be determined from at least one candidate access frequency based on the cellular wireless connection status of the terminal device, instead of randomly selecting the access frequency of the WiFi access point, interference between the WiFi network and the cellular network is avoided, improving the reliability of the terminal hardware and the user experience.

[0087] The method described in this application will now be illustrated through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other; identical or similar content will not be repeated in different embodiments.

[0088] Figure 2 This is a flowchart illustrating a wireless access method provided in an embodiment of this application. Please refer to... Figure 2 The method may include:

[0089] S201. Obtain the status and frequency of the cellular wireless connection of the terminal device.

[0090] The execution entity in this application embodiment can be a terminal device, or a chip, chip module, or wireless access device disposed in the terminal device. The wireless access device can be implemented through software or a combination of software and hardware. The terminal device can be a mobile phone, tablet computer, etc. The cellular wireless connection state can be idle or connected.

[0091] If a terminal device establishes a connection with a cellular network but does not transmit service data through the cellular network, the terminal device's cellular wireless connection state is idle. If a terminal device establishes a connection with a cellular network and is transmitting service data through the cellular network, the terminal device's cellular wireless connection state is connected.

[0092] The status and frequency of the cellular wireless connection of a terminal device can be determined through the application processor in the terminal device.

[0093] For example, after terminal device 1 enables cellular network, it accesses the cellular network and uses it for service transmission. At this time, the application processor of terminal device 1 obtains the cellular wireless connection status of terminal device 1 as connected.

[0094] S202. Determine the target WiFi frequency for WiFi wireless connection based on the status and frequency of the cellular wireless connection.

[0095] The target WiFi frequency for a WiFi wireless connection can be determined as follows: determine the Wi-Fi access point to be connected and at least one candidate access frequency of the WiFi access point; based on the status and frequency of the cellular wireless connection, determine the target WiFi frequency from at least one candidate access frequency.

[0096] The candidate access frequency can be determined based on the access frequency provided by the WiFi access point to be connected.

[0097] For example, if the WiFi access point to be connected provides access frequencies of 2.4GHz and 5GHz, then when terminal device 1 requests to access the WiFi network through the WiFi access point, the selectable access frequencies of the WiFi access point are 2.4GHz and 5GHz.

[0098] The target WiFi frequency can be determined as follows: if the cellular wireless connection is in an idle state, then any one of the at least one candidate access frequency is selected as the target WiFi frequency; if the cellular wireless connection is in a connected state, then the frequency of the current cellular wireless connection of the terminal device is obtained, and the target WiFi frequency is determined from at least one candidate access frequency based on the frequency of the current cellular wireless connection.

[0099] After determining the target WiFi frequency based on the status and frequency of the cellular wireless connection, the terminal device can access the WiFi access point according to the target WiFi frequency through the smart chip in the terminal device.

[0100] When the cellular wireless connection is in an idle state, after the terminal device connects to the WiFi network according to the target WiFi frequency, if the frequency of the cellular wireless connection is not below the intermediate frequency band, the current frequency of the cellular wireless connection of the terminal device needs to be reselected to a frequency below the intermediate frequency band. The intermediate frequency band can be a frequency band less than or equal to 2 GHz.

[0101] When determining the frequency for the adjusted current cellular wireless connection, the operator providing cellular network services to the terminal device is identified. Below the multiple mid-frequency bands of the cellular network provided by the operator, the frequency of the cellular network with the highest priority is determined as the frequency for the reselected current cellular wireless connection, according to the corresponding frequency priority.

[0102] For example, when terminal device 1 connects to a WiFi network, the candidate access frequencies are 2.4GHz and 5GHz. At this time, the application processor of terminal device 1 determines that the cellular wireless connection state of terminal device 1 is idle. Therefore, the smart chip of terminal device 1 determines that the candidate access frequency 2.4GHz is the target WiFi frequency. After terminal device 1 connects to the target WiFi frequency, the application processor of terminal device 1 obtains that the current cellular wireless connection frequency of terminal device 1 is 2.3GHz. Since the current cellular wireless connection frequency of terminal device 1, 2.3GHz, is greater than 2GHz, it is determined that the mobile operator providing cellular network services for terminal device 1 is operator B. Operator B provides cellular network frequencies in the low-frequency band including 700MHz~900MHz. The smart chip of terminal device 1, according to the corresponding frequency priority, determines the highest priority cellular network frequency, 700MHz, as the frequency for the reselected cellular wireless connection.

[0103] When the cellular wireless connection is in connected state, obtain the absolute value of the difference between each candidate access frequency and the current cellular wireless connection frequency; based on the absolute value of the difference between each candidate access frequency and the current cellular wireless connection frequency, determine the target WiFi frequency from at least one candidate access frequency, where the absolute value of the difference between the target WiFi frequency and the current cellular wireless connection frequency is the largest.

[0104] The maximum absolute value of the difference between the target WiFi frequency and the current cellular wireless connection frequency can avoid interference between WiFi and cellular networks, ensuring the quality of network services used by users through their terminal devices.

[0105] For example, when terminal device 1 accesses a WiFi network, the candidate access frequencies are 2.4GHz and 5GHz. At this time, the application processor of terminal device 1 determines that the cellular wireless connection state of terminal device 1 is connected, and the cellular wireless connection frequency is 2.3GHz. Based on the cellular wireless connection frequency and the candidate access frequencies, the absolute value of the difference between the candidate access frequency 2.4GHz and the cellular wireless connection frequency 2.3GHz is determined to be 0.1GHz. The absolute value of the difference between the candidate access frequency 5GHz and the cellular wireless connection frequency 2.3GHz is determined to be 2.7GHz. The absolute value of the difference between the candidate access frequency 5GHz and the cellular wireless connection frequency is greater than the absolute value of the difference between the candidate access frequency 2.4GHz and the cellular wireless connection frequency. Therefore, the candidate access frequency 5GHz can be determined as the target WiFi frequency.

[0106] The wireless access method provided in this application determines a WiFi access point to be connected and at least one candidate access frequency for the WiFi access point; obtains the cellular wireless connection status of the terminal device; and determines the target WiFi frequency for Wi-Fi wireless connection based on the cellular wireless connection status and frequency. In this process, because the target WiFi frequency for the WiFi access point can be determined from at least one candidate access frequency based on the cellular wireless connection status of the terminal device, instead of randomly selecting the access frequency of the WiFi access point, interference between the WiFi network and the cellular network is avoided, improving the reliability of the terminal hardware and the user experience.

[0107] Based on any of the above embodiments, the following, in conjunction with Figure 3 The detailed process of the wireless access method is explained.

[0108] Figure 3 This is a flowchart illustrating another wireless access method provided in an embodiment of this application. Please refer to... Figure 3 The method includes:

[0109] S301. Obtain the status and frequency of the cellular wireless connection of the terminal device.

[0110] The cellular wireless connection status can be either idle or connected.

[0111] S302. If the cellular wireless connection is in an idle state, determine any one of the at least one candidate access frequency as the target WiFi frequency.

[0112] For example, terminal device 1 requests access to a WiFi network, and the candidate access frequencies for the WiFi access point are 2.4GHz and 5GHz. If the application processor of terminal device 1 determines that the cellular wireless connection is in an idle state, then the smart chip of terminal device 1 can determine the candidate access frequency 2.4GHz as the target WiFi frequency.

[0113] S303. Obtain the frequency of the current cellular wireless connection of the cellular network currently accessed by the terminal device.

[0114] The frequency of the current cellular wireless connection of the cellular network currently accessed by the terminal device can be obtained through the application processor of the terminal device.

[0115] For example, after terminal device 1 accesses the cellular network, the application processor of terminal device 1 obtains the cellular wireless connection status as idle and the current cellular wireless connection frequency as 2.3GHz.

[0116] S304. Determine whether the frequency of the current cellular wireless connection is greater than or equal to the preset frequency.

[0117] If not, proceed with S305.

[0118] If so, execute S306.

[0119] The preset frequency can be 2GHz.

[0120] S305. Determine the frequency of the current cellular wireless connection as the frequency of the cellular wireless connection of the cellular network accessed by the terminal device.

[0121] If the current cellular wireless connection frequency is less than or equal to 1 GHz, there is no need to update the current cellular wireless connection frequency.

[0122] For example, after terminal device 1 accesses the cellular network, the application processor of terminal device 1 obtains the cellular wireless connection status as idle and the current cellular wireless connection frequency as 700MHz. At this time, the current cellular wireless connection frequency of 700MHz is determined to be the cellular wireless connection frequency of the cellular network accessed by terminal device 1.

[0123] S306. Among the cellular network frequencies that the terminal device can currently access, determine the first cellular network frequency.

[0124] The first cellular network frequency can be determined as follows: determine the network type and corresponding frequency priority of the cellular network in the area where the terminal device is located; based on the network type and frequency priority of the cellular network, determine the first cellular network frequency among the cellular network frequencies that the terminal device can currently access.

[0125] For example, suppose the mobile operator providing cellular network services to terminal device 1 is operator A, and operator A provides low-frequency bands for cellular network services ranging from 700MHz to 1GHz. Terminal device 1's cellular wireless connection is in an idle state, and the current cellular wireless connection frequency is 2.3GHz. The current cellular wireless connection frequency of terminal device 1 is higher than the preset frequency of 1GHz. Then, within the mid-frequency band of the cellular network provided by the operator, the smart chip of terminal device 1 determines the frequency of the highest priority cellular wireless connection as 800MHz, based on the network standard and frequency priority of the cellular network. The smart chip of terminal device 1 then determines 800MHz as the first cellular network frequency.

[0126] S307. Reselect the current cellular wireless connection frequency of the terminal device as the first cellular network frequency.

[0127] For example, if the current cellular wireless connection frequency of terminal device 1, as illustrated above, is 2.3 GHz, and the first cellular network frequency is 800 MHz, then the current cellular wireless connection frequency of the cellular network accessed by the terminal device will be reselected to the first cellular network frequency of 800 MHz.

[0128] Optionally, if the terminal device disconnects from the WiFi access point and the time interval is greater than or equal to a preset threshold, the terminal device's current cellular wireless connection frequency is reselected to the frequency of the initial cellular wireless connection.

[0129] The preset threshold can be configured according to the network environment and network quality. For example, the preset threshold can be 1 second.

[0130] For example, according to the example above, the current cellular wireless connection frequency of terminal device 1 is 2.3GHz, and the first cellular network frequency is 800MHz. When terminal device 1 disconnects from the WiFi access point, and the time interval is determined to be greater than a preset threshold of 1 second, terminal device 1 will reselect the current cellular wireless connection frequency to 2.3GHz.

[0131] S308. If the cellular wireless connection status is connected, obtain the absolute value of the difference between each candidate access frequency and the current cellular wireless connection frequency.

[0132] For example, terminal device 1 requests access to a WiFi network. The candidate access frequencies for the WiFi access point are 2.4GHz and 5GHz. Terminal device 1's cellular wireless connection state is connected, and the current cellular wireless connection frequency is 2.3GHz. The absolute value of the difference between the candidate access frequency 2.4GHz and the current cellular wireless connection frequency 2.3GHz is 0.1GHz. The absolute value of the difference between the candidate access frequency 5GHz and the current cellular wireless connection frequency 2.3GHz is 2.7GHz.

[0133] S309. The candidate access frequency with the largest frequency difference from the current cellular wireless connection frequency is determined as the target WiFi frequency.

[0134] For example, based on the absolute value of the difference between each candidate access frequency and the frequency of the current cellular connection as illustrated in the examples above, the candidate access frequency with the largest difference from the current cellular connection frequency can be determined to be 5GHz. This candidate access frequency, 5GHz, with the largest difference from the current cellular connection frequency, is then determined as the target WiFi frequency.

[0135] S310. Determine whether the absolute value of the difference between the target WiFi frequency and the frequency of the current cellular wireless connection is less than or equal to the first threshold.

[0136] If so, execute S311.

[0137] If not, proceed to S312.

[0138] The first threshold can be 1 GHz.

[0139] S311. Obtain the degree of mutual interference between the terminal device's WiFi wireless connection and cellular wireless connection.

[0140] The degree of mutual interference between the WiFi wireless connection and the cellular wireless connection of the terminal device can be obtained in the following way: obtain a first correspondence, which includes the degree of mutual interference between multiple WiFi frequencies and multiple cellular wireless connection frequencies; determine the degree of mutual interference between the WiFi wireless connection and the cellular wireless connection of the terminal device based on the target WiFi frequency, the current cellular wireless connection frequency and the first correspondence.

[0141] For example, the first correspondence can be shown in Table 1:

[0142] Table 1

[0143]

[0144] Assuming the current cellular wireless connection frequency is 2.567 GHz and the target WiFi frequency is 2.422 GHz, based on the target WiFi frequency, the current cellular wireless connection frequency, and the first correspondence shown in Table 1, the mutual interference level between the WiFi network provided by the WiFi access point and the cellular network is determined to be -86.

[0145] S312. Determine whether to activate the coexistence mechanism between WiFi wireless connection and cellular wireless connection of terminal device based on the degree of mutual interference.

[0146] The coexistence mechanism is a time-division multiplexing mechanism.

[0147] The coexistence mechanism between WiFi and cellular wireless connections on a terminal device can be determined as follows: if the mutual interference level is less than or equal to a second threshold, the coexistence mechanism is not activated; if the mutual interference level is greater than the second threshold, the coexistence mechanism is activated.

[0148] In the first correspondence, the degree of mutual interference between each WiFi frequency and the frequency of cellular wireless connection has its corresponding second threshold.

[0149] For example, based on the mutual interference levels shown in Table 1 above, the second threshold can be determined as shown in Table 2:

[0150] Table 2

[0151]

[0152] If a terminal device is simultaneously connected to both WiFi and cellular networks, and the mutual interference between the WiFi and cellular networks exceeds a second threshold, then the priority of the network services currently used by the terminal device can be determined, and the time period for network usage can be determined based on the priority order.

[0153] For example, terminal device 1 is simultaneously connected to both a WiFi network and a cellular network, and the mutual interference between the WiFi and cellular networks exceeds a second threshold. In this case, it is determined that terminal device 1 is using the network for voice calls and web browsing. The priority order of the services being used is voice calls, followed by web browsing. Therefore, after simultaneously connecting to both the WiFi and cellular networks, according to the priority order of the services being used, voice call data transmission is performed first, followed by web browsing data transmission.

[0154] For example, assuming the second threshold is -80, based on the mutual interference level illustrated in S312, the mutual interference level between the WiFi network and the cellular network provided by the WiFi access point is determined to be -86. According to Table 2, the current cellular wireless connection frequency is determined to be 2.567GHz, the target WiFi frequency is 2.422GHz, and the corresponding second threshold is -75. If the mutual interference level is less than or equal to the second threshold, then after accessing the WiFi access point at the target WiFi frequency of 2.422GHz, the multiplexing mechanism between the WiFi network and the cellular network is determined to be a normal coexistence mechanism.

[0155] S313. Connect to the WiFi access point according to the target WiFi frequency.

[0156] For example, if the target WiFi frequency is 5GHz, then terminal device 1 will access the WiFi access point according to the target WiFi frequency of 5GHz.

[0157] The wireless access method provided in this application determines a WiFi access point to be connected and at least one candidate access frequency for the WiFi access point. It acquires the cellular wireless connection status of the terminal device. If the cellular wireless connection status is idle, any one of the at least one candidate access frequency is determined as the target WiFi frequency, and the current cellular wireless connection frequency of the terminal device is updated. If the cellular wireless connection status is connected, the absolute value of the difference between each candidate access frequency and the current cellular wireless connection frequency is acquired. The candidate access frequency with the largest frequency difference from the current cellular wireless connection frequency is determined as the target WiFi frequency, and the WiFi access point is accessed according to the target WiFi frequency. If the absolute value of the difference between the target WiFi frequency and the current cellular wireless connection frequency is less than or equal to a first threshold, a multiplexing mechanism between the WiFi network and the cellular network provided by the WiFi access point is determined based on the degree of mutual interference. In the above process, since the target WiFi frequency of the WiFi access point can be determined from at least one candidate access frequency based on the cellular wireless connection status of the terminal device, instead of randomly selecting the access frequency of the WiFi access point, interference between the WiFi network and the cellular network is avoided, improving the hardware reliability and user experience of the terminal device.

[0158] Based on any of the above embodiments, the detailed process of the wireless access method will be illustrated below.

[0159] Example 1: The cellular wireless connection status of mobile phone 1 is idle.

[0160] When mobile phone 1 is connected to a cellular network, the current cellular wireless connection frequency is 2.3GHz. Mobile phone 1 is not using the cellular network for data transmission. If mobile phone 1 requests access to a WiFi network, and the WiFi access point provides access frequencies of 2.4GHz and 5GHz, then mobile phone 1's application processor can determine that the candidate access frequencies for the WiFi access point are 2.4GHz and 5GHz. At this time, mobile phone 1's application processor obtains that mobile phone 1's cellular wireless connection status is idle, so mobile phone 1 determines the candidate access frequency 5GHz as the target WiFi frequency and accesses the WiFi network through the WiFi access point according to the target WiFi frequency of 5GHz. At this time, it is determined that the current cellular wireless connection frequency of mobile phone 1 (2.3GHz) is greater than the preset frequency of 2GHz. Therefore, mobile phone 1's smart chip, within the low-frequency band (700MHz~900MHz) of the cellular network provided by the operator, determines the first cellular network frequency as 700MHz according to the network standard and frequency priority. Mobile phone 1's smart chip then reselects the frequency of the terminal device's current cellular wireless connection to the first cellular network frequency of 700MHz.

[0161] Example 2: The cellular wireless connection status of mobile phone 1 is connected, and the absolute value of the difference between the target WiFi frequency and the current cellular wireless connection frequency is greater than the first threshold.

[0162] When mobile phone 1 is connected to a cellular network and making a voice call, the current cellular wireless connection frequency is 2.3GHz. If mobile phone 1 requests access to a WiFi network, and the WiFi access point provides access frequencies of 2.4GHz and 5GHz, then the application processor of mobile phone 1 can determine that the candidate access frequencies of the WiFi access point are 2.4GHz and 5GHz. At this time, mobile phone 1 obtains the absolute value of the difference between each candidate access frequency and the current cellular wireless connection frequency, as shown in Table 3:

[0163] Table 3

[0164]

[0165] According to Table 3, the absolute value of the difference between the candidate access frequency 5GHz and the current cellular wireless connection frequency is the largest. Therefore, the candidate access frequency 5GHz is selected as the target WiFi frequency. Mobile phone 1 connects to the WiFi access point according to the target WiFi frequency of 5GHz.

[0166] After mobile phone 1 connects to the WiFi network, if the absolute value of the difference between the target WiFi frequency of 5GHz and the current cellular wireless connection frequency of 2.3GHz is greater than the first threshold of 1GHz, then mobile phone 1 can connect to the WiFi network at the target WiFi frequency and connect to the cellular network at the current cellular wireless connection frequency.

[0167] Example 3: The cellular wireless connection status of mobile phone 1 is connected, and the absolute value of the difference between the target WiFi frequency and the current cellular wireless connection frequency is less than or equal to the first threshold.

[0168] When mobile phone 1 is connected to a cellular network and making a voice call, the current cellular wireless connection frequency is 5GHz. If mobile phone 1 requests access to a WiFi network, and the WiFi access point provides access frequencies of 5GHz and 6GHz, then mobile phone 1's application processor can determine that the candidate access frequencies of the WiFi access point are 5GHz and 6GHz. At this time, mobile phone 1 obtains the absolute value of the difference between each candidate access frequency and the current cellular wireless connection frequency, as shown in Table 4:

[0169] Table 4

[0170]

[0171] According to Table 3, the absolute value of the difference between the candidate access frequency 6GHz and the current cellular wireless connection frequency is the largest. Therefore, 6GHz is selected as the target WiFi frequency. Mobile phone 1 connects to the WiFi access point at the target WiFi frequency of 6GHz.

[0172] After mobile phone 1 connects to the WiFi network, if the absolute value of the difference between the target WiFi frequency (6GHz) and the current cellular wireless connection frequency (5GHz) is equal to the first threshold (1GHz), then the mutual interference level between the wireless network provided by WiFi access point router 3 and the cellular network is determined to be -65. If the mutual interference level is greater than the second threshold (-70), then the multiplexing mechanism is determined to be time-division multiplexing. At this time, it is determined that mobile phone 1 is using network services including voice calls and web browsing. The priority order of network services is voice calls, followed by web browsing. Therefore, after mobile phone 1 connects to both the WiFi network and the cellular network simultaneously, according to the priority order of network services, it first uses the network for voice call data transmission, and then for web browsing data transmission.

[0173] The wireless access process provided in this application embodiment illustrates the following: A WiFi access point to be connected and at least one candidate access frequency for that WiFi access point are determined. The cellular wireless connection status of the terminal device is obtained. If the cellular wireless connection status is idle, any one of the at least one candidate access frequency is selected as the target WiFi frequency, and the current cellular wireless connection frequency of the terminal device is updated. If the cellular wireless connection status is connected, the absolute value of the difference between each candidate access frequency and the current cellular wireless connection frequency is obtained. The candidate access frequency with the largest frequency difference from the current cellular wireless connection frequency is selected as the target WiFi frequency, and the WiFi access point is accessed according to the target WiFi frequency. If the absolute value of the difference between the target WiFi frequency and the current cellular wireless connection frequency is less than or equal to a first threshold, a multiplexing mechanism between the WiFi network and the cellular network provided by the WiFi access point is determined based on the degree of mutual interference. In the above process, since the target WiFi frequency of the WiFi access point can be determined from at least one candidate access frequency based on the cellular wireless connection status of the terminal device, instead of randomly selecting the access frequency of the WiFi access point, interference between the WiFi network and the cellular network is avoided, improving the reliability of the terminal hardware and the user experience.
