[0101] The communication method involved in the embodiment of the present disclosure may include at least one of step S201 to step S202. For example, step S201 may be implemented as an independent embodiment, and step S202 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0102] In some embodiments, steps S201 and S202 may be performed in an interchangeable order or simultaneously.

[0103] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0104] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0105] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2 .

[0106] In some embodiments, when a terminal is under the coverage of multiple types of networks, the terminal can switch from a network that has been connected to another type of network to ensure a relatively good communication effect.

[0107] In some embodiments, the network type includes at least one of the following: cellular, WiFi, and Bluetooth. It should be understood that the network types in the embodiments of the present disclosure are not limited to these types and may include other types. The following embodiments mainly use cellular and WiFi to illustrate the technical solutions of the present disclosure.

[0108] For example, when a terminal is connected to a WiFi network, it is also covered by a cellular network. That is, the terminal is covered by both the WiFi network and the cellular network. In this case, the terminal can monitor the channel quality parameters of the WiFi network and the cellular network, and then determine whether to switch from the WiFi network to the cellular network based on the monitoring results.

[0109] It should be noted that monitoring the channel quality parameters of the cellular network may include monitoring the channel quality parameters of at least one cell in the cellular network, and switching of the terminal to the cellular network may refer to switching to a cell in the cellular network.

[0110] In some embodiments, the terminal may monitor the Reference Signal Receiving Power (RSRP) of the cellular network and the Received Signal Strength Indication (RSSI) of the WiFi network. When the RSSI of the WiFi network is less than the RSSI roaming-out threshold and the RSRP of the cellular network is greater than the RSRP roaming-in threshold, it can be determined that the channel quality of the WiFi network is relatively poor and the channel quality of the cellular network is relatively good, and the terminal may switch from the currently connected WiFi network to the cellular network.

[0111] For example, when a terminal is connected to a cellular network, it is also covered by a WiFi network, that is, the terminal is covered by both the WiFi network and the cellular network. In this case, the terminal can monitor the channel quality parameters of the WiFi network and the cellular network, and then determine whether to switch from the cellular network to the WiFi network based on the monitoring results.

[0112] In some embodiments, the terminal may monitor the RSRP of the cellular network and the RSSI of the WiFi network. When the RSRP of the cellular network is less than the RSRP Rove-out threshold and the RSSI of the WiFi network is greater than the RSSI Rove-in threshold, it can be determined that the channel quality of the cellular network is relatively poor and the channel quality of the WiFi network is relatively good, and the terminal may switch from the currently connected cellular network to the WiFi network.

[0113] In the above embodiment, the terminal primarily determines whether to switch from one network to another based on the RSRP of the cellular network and the RSSI of the WiFi network. However, for cellular networks, RSRP does not fully represent channel quality, so RSRP alone is not sufficient to accurately determine cellular network channel quality. Similarly, for WiFi networks, RSSI does not fully represent channel quality, so RSSI alone is not sufficient to accurately determine WiFi network channel quality. Therefore, determining whether to switch from one network to another based solely on the RSRP of the cellular network and the RSSI of the WiFi network may not guarantee that the terminal will receive higher communication quality after switching networks.

[0114] In a first aspect, embodiments of the present disclosure provide a network switching method. Figure 3 is a schematic flow chart illustrating a network switching method according to an embodiment of the present disclosure. The network switching method illustrated in this embodiment can be executed by a terminal.

[0115] As shown in FIG3 , the network switching method may include the following steps:

[0116] In step S301, a channel quality parameter of a first type of network is monitored, wherein the channel quality parameter includes at least one of the following parameters: reference signal received power RSRP, received signal strength indication RSSI, and other parameters.

[0117] In step S302, it is determined whether to switch from the accessed second type network to the first type network according to the channel quality parameter.

[0118] It should be noted that the embodiment shown in FIG. 3 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0119] According to an embodiment of the present disclosure, when a terminal accesses a second type of network and is still under the coverage of a first type of network, the terminal can monitor the channel quality parameters of the first type of network, wherein the channel quality parameters monitored by the terminal include at least one of the following parameters: RSRP, RSSI and other parameters.

[0120] In some embodiments, the first type of network includes at least one of the following: a cellular network; or WiFi.

[0121] In some embodiments, the first type of network includes a cellular network, and the channel quality parameter includes RSRP.

[0122] In some embodiments, the first type of network includes WiFi, and the channel quality parameter includes RSSI.

[0123] For example, when the first type of network includes a cellular network, the channel quality parameters monitored by the terminal for the cellular network may include RSRP and other parameters; when the first type of network includes a WiFi network, the channel quality parameters monitored by the terminal for the WiFi network may include RSSI and other parameters.

[0124] In an embodiment of the present disclosure, when the terminal determines whether to switch from the second type of network to the first type of network, in addition to determining the channel quality of the first type of network based on RSRP and RSSI, other parameters may also be considered. This is conducive to more accurately determining the channel quality of the first type of network, so that the terminal can switch to the first type of network only when it is accurately determined that the channel quality of the first type of network is relatively high, thereby ensuring that the terminal can obtain higher communication quality after switching to the first type of network.

[0125] In some embodiments, the first type of network includes a cellular network, and the other parameters include at least one of the following:

[0126] Signal to Interference plus Noise Ratio (SNR), also known as SINR;

[0127] Packet Data Convergence Protocol (PDCP) Tx data buffer, where PDCP stands for Packet Data Convergence Protocol and Tx stands for transmission.

[0128] Block Error Rate BLER (Block Error Rate), can also be referred to as bit error rate for short.

[0129] It should be noted that when the first type of network includes a cellular network, other parameters are not limited to the above-mentioned SNR, PDCP Tx data buffer, and BLER, and may also include other parameters for characterizing channel quality, such as noise power, channel bandwidth, reference signal receiving quality (RSRQ), etc., which are not limited in this disclosure.

[0130] In some embodiments, when the first type of network includes a cellular network, the terminal can monitor not only the RSRP of the cellular network but also parameters characterizing channel quality, such as the SNR, PDCP Tx data buffer, and BLER. This allows the terminal to more accurately determine the channel quality of the cellular network and only switch to the cellular network when it accurately determines that the channel quality of the cellular network is relatively high, thereby ensuring that the terminal can obtain higher communication quality after switching to the cellular network.

[0131] In some embodiments, the first type of network includes WiFi, and the other parameters include at least one of the following:

[0132] Channel busy and blocked information, such as CCA_busy / wait_dur, where CCA stands for Clear Channel Assessment;

[0133] Automatic anti-interference ANI (Adaptive Noise Immunity);

[0134] The number of transmitted packets retransmitted per second, for example, can be called tx_retry;

[0135] The number of failed transmission packets per second, which can be called tx_bad, for example.

[0136] It should be noted that when the first type of network includes a WiFi network, other parameters are not limited to the above-mentioned channel busy blocking information, ANI, tx_retry, and tx_bad, and may also include other parameters for characterizing channel quality, such as noise power, channel bandwidth, RSRQ, etc., which are not limited in this disclosure.

[0137] In some embodiments, when the first type of network includes a WiFi network, the terminal can monitor not only the RSSI of the WiFi network but also parameters representing channel quality, such as channel congestion information, ANI, tx_retry, and tx_bad. This allows the terminal to more accurately determine the WiFi network's channel quality and only switch to the WiFi network when it accurately determines that the WiFi network's channel quality is relatively high, thereby ensuring higher communication quality after the terminal switches to the WiFi network.

[0138] In some embodiments, determining whether to switch from the accessed second type network to the first type network according to the channel quality parameter includes:

[0139] The value of each parameter in the channel quality parameter satisfies a first association relationship with a first parameter threshold corresponding to the parameter, and it is determined to switch from the accessed second type network to the first type network.

[0140] In some embodiments, for each channel quality parameter, a first parameter threshold corresponding to the parameter may be set. For example, the first parameter threshold may be referred to as a roaming-in threshold of the parameter.

[0141] For example, when the first type of network is a cellular network and the second type of network is a WiFi network, the channel quality parameters of the cellular network may include RSRP, SNR, PDCP Tx data cache, and BLER. The roaming entry threshold of RSRP is RSRP-Rove in, the roaming entry threshold of SNR is SNR-Rove in, the roaming entry threshold of PDCP Tx data cache is PDCP Tx data cache-Rove in, and the roaming entry threshold of BLER is BLER-Rove in.

[0142] The first association relationship between the parameter and the corresponding first parameter threshold value may be different for different parameters. For example, for RSRP, the first association relationship may be RSRP greater than or equal to RSRP-Rove in, while for BLER, the first association relationship may be BLER less than BLER-Rove in.

[0143] For example, when the terminal determines that the RSRP of the cellular network is greater than or equal to RSRP-Rove in, the SNR is greater than or equal to SNR-Rove in, the PDCP Tx data buffer is less than PDCP Tx data buffer-Rove in, and the BLER is less than BLER-Rove in, the terminal can determine that the value of each parameter in the channel quality parameter satisfies a first association relationship with the first parameter threshold corresponding to the parameter. In this case, the terminal can determine that the channel quality of the cellular network is relatively good, and thus switch from the WiFi network to the cellular network, for example, switch to a cell in the cellular network.

[0144] It should be noted that, in some embodiments, when determining whether to switch from the connected second type network to the first type network, in addition to considering whether the value of each parameter in the channel quality parameter of the first type network and the first parameter threshold corresponding to the parameter satisfy the first association relationship, it may also be considered whether the value of each parameter in the channel quality parameter of the second type network and the third parameter threshold corresponding to the parameter satisfy the third association relationship. The third parameter threshold may be referred to as a roaming-out threshold.

[0145] For example, when the first type of network is a cellular network and the second type of network is a WiFi network, the channel quality parameters of the WiFi network may include RSSI, channel busy and blocked information, ANI, tx_retry, and tx_bad. The roaming-out threshold of RSSI is RSSI-Rove out, the roaming-out threshold of channel busy and blocked information is channel busy and blocked-Rove out, the roaming-out threshold of ANI is ANI-Rove out, the roaming-out threshold of tx_retry is tx_retry-Rove out, and the roaming-out threshold of tx_bad is tx_bad-Rove out.

[0146] The third association relationship between the parameter and the corresponding third parameter threshold value may be different for different parameters. For example, for RSSI, the third association relationship may be RSSI less than RSSI-Rove out, while for ANI, the third association relationship may be ANI greater than or equal to ANI-Rove out.

[0147] For example, when the terminal determines that the RSSI of the cellular network is less than RSSI-Rove out, and the channel busy and blocked information is greater than or equal to channel busy and blocked-Rove out, and the ANI is greater than or equal to ANI-Rove out, and the tx_retry is greater than or equal to tx_retry-Rove out, and the tx_bad is greater than or equal to tx_bad-Rove out, in this case, the terminal can determine that the channel quality of the WiFi network is relatively poor, and thus can switch from the WiFi network to the cellular network, for example, switch to a cell in the cellular network.

[0148] In some embodiments, determining whether to switch from the accessed second type network to the first type network according to the channel quality parameter further includes:

[0149] If the value of any parameter in the channel quality parameters does not satisfy the first correlation relationship with the first parameter threshold corresponding to the parameter, a score is determined according to the value of each parameter in the channel quality parameters;

[0150] If the score is greater than or equal to the first score threshold, it is determined to switch from the accessed second type network to the first type network; if the score is less than the first score threshold, it is determined not to switch from the accessed second type network to the first type network.

[0151] In some embodiments, when the value of any parameter among the channel quality parameters of the first type of network monitored by the terminal does not satisfy a first correlation relationship with a first parameter threshold corresponding to the parameter, it can be determined that the parameter is insufficient to indicate that the channel quality of the first type of network is relatively good. In this case, the terminal can determine a score based on the value of each parameter in the channel quality parameter. Since the score is obtained based on each parameter in the channel quality parameter, it can more comprehensively characterize the quality of the channel. For example, when the score is greater than or equal to the first score threshold, the terminal can determine that the channel quality is relatively good, and thus switch from the connected second type of network to the first type of network; when the score is less than the first score threshold, the terminal can determine that the channel quality is relatively poor, and then do not switch from the connected second type of network to the first type of network, that is, continue to communicate in the second type of network.

[0152] In some embodiments, determining whether to switch from the accessed second type network to the first type network according to the channel quality parameter further includes:

[0153] if the value of any parameter among the channel quality parameters does not satisfy a first association relationship with the first parameter threshold corresponding to the parameter, determining a first score according to the value of each parameter among the channel quality parameters of the first type of network, and determining a second score according to the value of each parameter among the channel quality parameters of the second type of network;

[0154] Among them, if the first score is greater than the second score, it is determined to switch from the second type of network to the first type of network; if the first score is less than or equal to the second score, it is determined not to switch from the second type of network to the first type of network.

[0155] In some embodiments, when the value of any parameter among the channel quality parameters of the first type of network monitored by the terminal does not satisfy the first association relationship with the first parameter threshold corresponding to the parameter, it can be determined that the parameter is not sufficient to indicate that the channel quality of the first type of network is relatively good. In this case, the terminal can determine a first score based on the value of each parameter in the channel quality parameters of the first type of network, and determine a second score based on the value of each parameter in the channel quality parameters of the second type of network.

[0156] Since the score is obtained based on each parameter in the channel quality parameter, it can more comprehensively characterize the quality of the channel. For example, when the first score is greater than the second score, the terminal can determine that the channel quality of the first type of network is better than the channel quality of the second type of network, and thus switch from the second type of network to the first type of network. When the first score is less than or equal to the second score threshold, the terminal can determine that the channel quality of the first type of network is not better than the channel quality of the second type of network, and then does not switch from the second type of network to the first type of network, that is, continues to communicate in the second type of network.

[0157] In some embodiments, the method of determining the score based on the value of each parameter in the channel quality parameter includes but is not limited to obtaining the score by weighted summation of each parameter, and inputting each parameter into a model pre-determined by machine learning to output the score.

[0158] In some embodiments, determining whether to switch from the accessed second type network to the first type network according to the channel quality parameter further includes:

[0159] If the value of any parameter in the channel quality parameters does not satisfy the first association relationship with the first parameter threshold corresponding to the parameter, it is determined not to switch from the accessed second type network to the first type network.

[0160] In some embodiments, when the value of any parameter of the channel quality parameters of the first type of network monitored by the terminal does not satisfy the first association relationship with the first parameter threshold corresponding to the parameter, it can be determined that the parameter is not sufficient to indicate that the channel quality of the first type of network is relatively good. In this case, the terminal determines not to switch from the second type of network to which it is connected to to the first type of network, that is, to continue to communicate in the second type of network.

[0161] In some embodiments, determining whether to switch from the accessed second type network to the first type network according to the channel quality parameter includes:

[0162] determining a score based on the value of each of the channel quality parameters;

[0163] If the score is greater than or equal to the first score threshold, it is determined to switch from the accessed second type network to the first type network; if the score is less than the first score threshold, it is determined not to switch from the accessed second type network to the first type network.

[0164] In some embodiments, the terminal may determine a score based on the value of each parameter in the channel quality parameter. Since the score is obtained based on each parameter in the channel quality parameter, the quality of the channel may be comprehensively characterized. For example, when the score is greater than or equal to a first score threshold, the terminal may determine that the channel quality is relatively good, thereby switching from the second type of network to the first type of network; when the score is less than the first score threshold, the terminal may determine that the channel quality is relatively poor, and then the terminal will not switch from the second type of network to the first type of network, that is, continue to communicate in the second type of network.

[0165] In some embodiments, determining whether to switch from the accessed second type network to the first type network according to the channel quality parameter includes:

[0166] Determine a first score based on the value of each parameter in the channel quality parameters of the first type of network, and determine a second score based on the value of each parameter in the channel quality parameters of the second type of network;

[0167] Among them, if the first score is greater than the second score, it is determined to switch from the second type of network to the first type of network; if the first score is less than or equal to the second score, it is determined not to switch from the second type of network to the first type of network.

[0168] In some embodiments, when the terminal can determine a first score based on the value of each parameter in the channel quality parameters of the first type of network, and determine a second score based on the value of each parameter in the channel quality parameters of the second type of network, since the scores are obtained based on each parameter in the channel quality parameters, the channel quality can be more comprehensively represented.

[0169] For example, when the first score is greater than the second score, the terminal may determine that the channel quality of the first type of network is better than the channel quality of the second type of network, and thus switch from the connected second type of network to the first type of network; when the first score is less than or equal to the second score threshold, the terminal may determine that the channel quality of the first type of network is not better than the channel quality of the second type of network, and then do not switch from the connected second type of network to the first type of network, that is, continue to communicate in the second type of network.

[0170] In some embodiments, the method of determining the score based on the value of each parameter in the channel quality parameter includes but is not limited to obtaining the score by weighted summation of each parameter, and inputting each parameter into a model pre-determined by machine learning to output the score.

[0171] In some embodiments, when a first condition is met, a channel quality parameter of the first type of network is monitored, wherein the first condition includes at least one of the following:

[0172] The value of any parameter among the channel quality parameters of the second type of network and the second parameter threshold corresponding to the parameter satisfy a second association relationship;

[0173] The terminal is in the first scenario.

[0174] The terminal may monitor the channel quality parameters of the first type of network only when it determines that the first condition is met (for example, the terminal meets the first condition, or the channel quality parameter meets the first condition), and when the first condition is not met, it is not necessary to monitor the channel quality parameters of the first type of network.

[0175] In some embodiments, the second type of network includes at least one of the following: a cellular network; or a WiFi network. When the first type of network is a cellular network, the second type of network may be a WiFi network; and when the first type of network is a WiFi network, the second type of network may be a cellular network.

[0176] In some embodiments, when the value of any parameter among the channel quality parameters of the second type network satisfies a second correlation relationship with the second parameter threshold corresponding to the parameter, it can be determined that the channel quality of the second type network currently accessed by the terminal is relatively poor.

[0177] In some embodiments, the second type of network is a cellular network, and the channel quality parameter of the second type of network may include at least one of the following: RSRP, SNR, PDCP Tx data buffer, and BLER. Other parameters used to characterize channel quality may also be included, such as noise power, channel bandwidth, RSRQ, etc., which are not limited by the present disclosure.

[0178] In some embodiments, the second type of network is a WiFi network, and the channel quality parameter of the second type of network may include at least one of the following: RSSI, channel busy and blocked information, ANI, tx_retry, and tx_bad. Other parameters used to characterize channel quality may also be included, such as noise power, channel bandwidth, RSRQ, etc., which are not limited by the present disclosure.

[0179] For example, the second parameter threshold can be called a roaming-out threshold. When the second type of network is a cellular network and the first type of network is a WiFi network, the channel quality parameters of the cellular network may include RSRP, SNR, PDCP Tx data cache, and BLER. The roaming-out threshold of RSRP is RSRP-Rove out, the roaming-out threshold of SNR is SNR-Rove out, the roaming-out threshold of PDCP Tx data cache is PDCP Tx data cache-Rove out, and the roaming-out threshold of BLER is BLER-Rove out.

[0180] The second association relationship between the parameter and the corresponding second parameter threshold value may be different for different parameters. For example, for RSRP, the second association relationship may be RSRP less than RSRP-Rove out, while for BLER, the second association relationship may be BLER greater than or equal to BLER-Rove out.

[0181] For example, when the terminal determines that the RSRP of the cellular network is less than RSRP-Rove out, or the SNR is less than SNR-Rove out, or the PDCP Tx data buffer is greater than or equal to PDCP Tx data buffer-Rove out, or the BLER is greater than or equal to BLER-Rove out, the terminal may determine that the value of each parameter in the channel quality parameter satisfies a second association relationship with the second parameter threshold corresponding to the parameter. In this case, the terminal may determine that the channel quality of the cellular network is relatively poor and may consider switching to a WiFi network, thereby starting to monitor the channel quality parameters of the WiFi network.

[0182] In some embodiments, the terminal is in the first scenario and can determine that the channel quality of the second type of network has changed. In this case, the channel quality of the second type of network may deteriorate, so it can be considered to switch to the first type of network, so that the channel quality parameters of the first type of network can be monitored.

[0183] In some embodiments, the second type of network includes a cellular network, and the first scenario includes at least one of the following: initial registration; cell handover; cell reselection; and redirection.

[0184] In some embodiments, the second type of network includes WiFi, and the first scenario includes at least one of the following: initial connection; channel change; WiFi roaming.

[0185] In some embodiments, the first type of network may not be limited to one type of network, and may be one or more types of networks.

[0186] When the terminal determines that it needs to switch to multiple types of networks, the terminal can switch to a network that matches the service among the multiple types of networks based on the association between the service and the network type.

[0187] Taking the first type of network as an example of multiple types of networks, for example, the first type of network includes a new radio (NR) network and a WiFi network in a cellular network, and the second type of network includes a long term evolution (LTE) network in a cellular network. The terminal can monitor the channel quality parameters of the NR network and the WiFi network.

[0188] The terminal can determine the NR network and the WiFi network based on the monitoring results. For example, it can determine score #1 based on each parameter in the channel quality parameters of the NR network, and determine score #2 based on each parameter in the channel quality parameters of the WiFi network, and compare score #1 and score #2. When score #1 is greater than score #2, it can be determined that the channel quality of the NR network is better, and the terminal will switch to the NR network. When score #2 is greater than score #1, it can be determined that the channel quality of the WiFi network is better, and the terminal will switch to the WiFi network.

[0189] When score #1 equals score #2, the terminal determines that it needs to switch to both the NR network and the WiFi network, but this is not possible. Therefore, the terminal can determine the service currently being or to be performed. When the service matches NR, for example, the service includes VoNR (Voice over NR, new air interface voice bearer), the terminal can determine to switch to the NR network. When the service matches WiFi, for example, the service includes VoWiFi (Voice over WiFi, WiFi voice bearer), the terminal can determine to switch to the WiFi network. This helps ensure that the terminal can smoothly carry out the service currently being or to be performed on the network it switches to.
