[0033] Example 1

[0034] The method embodiment provided in the first embodiment of the present application can be executed in a mobile phone, a tablet, a satellite phone or a similar computing device. Taking running on a mobile phone as an example, Figure 1 FIG. 1 is a hardware structure diagram of a mobile phone according to an embodiment of the present invention. Figure 1 As shown, the mobile phone may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data.

It can be understood by those skilled in the art that Figure 1 The structure shown is for illustration only and does not limit the structure of the mobile phone. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

[0036] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile phone. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0037] In this embodiment, a communication network adjustment method is provided. Figure 2 is a flow chart of a communication network adjustment method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0038] Step S202, obtaining first communication quality information of a cellular communication network of a target terminal;

[0039] The communication quality information of this embodiment includes call quality information and / or network quality information. Taking call quality information as an example, the call quality information corresponds to data throughput, call jamming, call clarity, and real-time Internet access rate during a call.

[0040] By acquiring information such as the working frequency band, working channel, receiving level, received signal strength indicator (RSSI), power, noise factor, reference signal received power (RSRP), bandwidth and signal-to-noise ratio of the current communication link, one or more of the above parameter information is determined as communication quality information, and the communication quality information can also be calculated based on the mapping relationship between the above parameter information and the communication quality information.

[0041] Step S204, determining whether the first communication quality information meets a preset communication quality requirement;

[0042] Step S206, when the first communication quality information does not meet the preset communication quality requirement, adaptively adjust the parameters of the communication link of the cellular communication network so that the cellular communication network meets the preset communication quality requirement, wherein the parameters of the communication link include at least one of the following: frequency band, bandwidth, modulation mode, main diversity.

[0043] Through the above steps, the first communication quality information of the cellular communication network of the target terminal is obtained; it is determined whether the first communication quality information meets the preset communication quality requirements; when the first communication quality information does not meet the preset communication quality requirements, the parameters of the communication link of the cellular communication network are adaptively adjusted to make the cellular communication network meet the preset communication quality requirements. By obtaining the communication quality information of the cellular communication network of the target terminal, when the communication quality information does not meet the preset communication quality requirements, the parameters of the communication link of the cellular communication network are adaptively adjusted, thereby ensuring the signal strength of the cellular communication network anytime and anywhere, solving the technical problem in the related technology that the communication terminal is prone to weak signals, and the communication terminal can always maintain a good communication connection in crowded places, thereby improving the user experience.

[0044] Optionally, before obtaining the first communication quality information of the cellular communication network of the target terminal, it also includes: reading the number of signal grids of the cellular communication network displayed on the terminal interface of the target terminal; determining whether the number of signal grids is less than a preset number; if the number of signal grids is less than the preset number, determining to obtain the first communication quality information of the cellular communication network of the target terminal.

[0045] First, a relatively simple solution is used to detect whether the call quality of the current communication link is good, such as the number of signal grids displayed on the mobile phone interface. If the number of signal grids is greater than the preset number, such as full grids, the process ends; if the call quality is not good, the number of signal grids is less than the preset number, the first communication quality information is further obtained, and then the signal strength value of the current communication link is calculated based on the first communication quality information. This can prevent the communication network from being triggered to make adaptive adjustments when the signal is good, saving terminal energy consumption.

[0046] In an example of this embodiment, determining whether the first communication quality information meets the preset communication quality requirements includes: determining a signal strength value of the cellular communication network based on the first communication quality information; determining whether the signal strength value exceeds a preset threshold range; and if the signal strength value exceeds the preset threshold range, determining that the first communication quality information does not meet the preset communication quality requirements.

[0047] In this example, the communication quality information includes multiple communication quality parameters, and one or more communication quality parameters of the current communication link, such as the working frequency band, working channel, receiving level, received signal strength indication (RSSI), power, noise coefficient, reference signal received power (RSRP), bandwidth and signal-to-noise ratio, are obtained according to the communication frequency band and channel opened in the communication link. The signal strength value of the current cellular communication network, referred to as signal strength, is calculated by pre-establishing a mapping relationship (mapping table) between the above communication quality parameters and signal strength. Signal strength is an indicator for judging call quality based on the information obtained. In this example, the mapping table may include the relationship between signal strength and one or more communication quality parameters such as communication standard, frequency band, frequency point, bandwidth, number of time slots, modulation mode, reference signal received power, received signal strength indication, signal-to-noise ratio and transmission power. The communication standards include GSM (Global System for Mobile Communication), WCDMA (Wideband Code Division Multiple Access), LTE (Long Term Evolution), NR (New Radio), etc. The frequency bands are the frequency bands supported by terminal equipment and base stations. The modulation methods of GSM include GMSK (Gaussian Filtered Minimum Shift Keying) and 8PSK (8 Phase Shift Keying), and the modulation methods of WCDMA, LTE and NR include QPSK (Quadrature Phase Shift Keying), 16QAM (Quadrature Amplitude Modulation), 64QAM and 256QAM. There is a corresponding signal strength under each communication standard, communication mode, communication frequency band and bandwidth. By establishing a mapping table, when the terminal device performs wireless communication, the mapping table is called to check whether its signal strength value exceeds the preset threshold range. If it exceeds, the communication link is adaptively adjusted.

[0048] When judging whether the signal strength value exceeds the preset threshold range, the absolute value of the difference between the signal strength and the preset signal strength of the communication link is used to judge whether the absolute value exceeds the preset threshold range. If it exceeds, the communication link is adaptively adjusted to meet the current call requirements; if not, the process ends. For example, if the preset signal strength is -85 and the real-time measured signal strength of the current link is -120, then the absolute value of their difference is 35. If the preset threshold range is 10, then the signal strength of the current link does not meet the requirements, and the call quality does not meet the requirements, and it needs to be adaptively adjusted.

[0049] In this embodiment, the adaptive adjustment of the parameters of the communication link of the cellular communication network includes parameter adjustment within the same communication link and parameter adjustment between different communication links. If the adaptive adjustment of the communication link meets the call requirements, the process ends. The adjustment order of the same communication link and different communication links is to first adjust the same communication link, and then adjust the different communication links. During the adaptive adjustment, the link set and the parameter set are switched in sequence (such as from small to large). The adjustment sequence does not need to switch back and forth between different parameters, which is beneficial to saving power consumption of the terminal device. The following describes two adaptive adjustment methods:

[0050] In one implementation of the present embodiment, adaptive parameter adjustment is performed between different communication links, and adaptive adjustment of the communication link and bandwidth of the cellular communication network includes: determining a first communication link where the cellular communication network is currently located, wherein the cellular communication network includes multiple communication links, and each communication link corresponds to a frequency band; starting from the first communication link, performing the following operations in sequence until the last communication link or the adaptive adjustment ends: adaptively adjusting link parameters within the current communication link; after the adaptive adjustment of the current communication link ends, determining whether the adjusted current communication link meets the preset communication quality requirements; if the adjusted current communication link does not meet the preset communication quality requirements, switching the current communication link to the next communication link of the cellular communication network; if the adjusted current communication link meets the preset communication quality requirements, determining that the adaptive adjustment of the cellular communication network ends.

[0051] In this embodiment, adaptive parameter adjustment is performed within the same communication link, and adaptive adjustment of link parameters within the current communication link includes: determining a first bandwidth currently configured for a first communication link, wherein the first communication link includes multiple bandwidths, each bandwidth corresponding to a sub-band of the first communication link; starting from the first bandwidth, performing the following operations in sequence until the last bandwidth or the adaptive adjustment ends: adjusting the modulation mode and / or main diversity of the current communication link within the current bandwidth; determining whether the current communication link after adjustment meets the preset communication quality requirements; if the current communication link after adjustment does not meet the preset communication quality requirements, switching the current bandwidth to the next bandwidth of the current communication link; if the current communication link after adjustment meets the preset communication quality requirements, determining that the adaptive adjustment of the current communication link ends.

[0052] The adjustments between the same communication links mainly include bandwidth, modulation mode and primary diversity. The bandwidth and modulation mode of the same link are supported by the terminal equipment and the wireless communication base station. Figure 3 It is a bandwidth diagram of a cellular communication network in an embodiment of the present invention. The current communication link includes 1 to 7 bandwidths, that is, 7 resource blocks RB (bandwidth units). When the terminal device performs adaptive adjustment, it starts from part 1 of the current communication link. If the call quality requirements are met at 1 (bandwidth 1), the adaptive adjustment is completed and the process ends. The adjustment at 1 can switch different modulation modes to see whether the call quality requirements can be met under each modulation mode. It can also be that the modulation mode is switched once in each frequency band to see whether it can meet the call quality requirements. If the call quality at 1 does not meet the requirements, continue to adjust to the next part 2. If the call quality requirements are met, the process ends; if not, continue to the next part 3, and so on, until all bandwidths of the communication link are adjusted. For example, the current communication link frequency band is B1, and the communication receiving bandwidth is 2110MHz~2120MHz. If the current call quality does not meet the requirements, the terminal device performs adaptive adjustment. The receiving frequency of B1 is 2110MHz~2170MHz, and the adaptive adjustment is performed with a bandwidth of 10MHz. The terminal equipment adaptively switches to 2120MHz~2130MHz to see if it meets the call quality requirements. If it does, the adaptive adjustment ends; if it does not, it continues to switch to the next bandwidth of 2130MHz~2140MHz to see if it meets the call quality requirements. This continues in sequence until the entire bandwidth is adjusted to see if it meets the call quality requirements. The radiation area of ​​a single bandwidth is greater than or equal to one adjustment cell.

[0053] Figure 4It is a schematic diagram of the main diversity of a certain bandwidth in an embodiment of the present invention. Bandwidth 1 includes 4 main diversity. They are PRX (main set reception), DRX (diversity reception), PRX2, and DRX2. When the adaptive communication link is adjusted to a certain bandwidth and resource block, the terminal device automatically checks its current main diversity opening status. If only the main set reception is currently opened and the call quality does not meet the requirements, the terminal device automatically opens the corresponding diversity; if the call quality requirements are still not met, if the frequency band has four-way reception, the terminal device opens other channels again to see whether it meets the call quality requirements. If it meets, the adaptive adjustment ends; if it does not meet, it is adaptively adjusted to the next frequency band. For example, the current communication frequency band is B1, the communication reception bandwidth is 2110MHz~2120MHz, and only the main set reception, that is, PRX, is opened during the current communication. When the mobile phone is adaptively adjusted, DRX is first turned on to see whether it meets the call quality requirements. If it meets, the adaptive adjustment ends; if it does not meet, PRX2 and DRX2 are turned on again in sequence to see whether it meets the call quality requirements. If it does not meet, it is adaptively adjusted to the next bandwidth. If the channel has PRX, DRX, PRX2 and DRX2, adaptive adjustments are performed in sequence. If there are only PRX and DRX, adjust until DRX ends and perform the next bandwidth adjustment; or if there is only PRX, this step is not required for adaptive adjustment. If PRX, DRX, PRX2 and DRX2 of the frequency band are already turned on when the check starts, this step is not required. For example, only PRX is turned on for the call band of B1, and it has DRX, PRX2 and DRX2, so this step is performed in sequence; if B1 only has PRX or PRX and DRX or PRX, DRX, PRX2 and DRX2 are all turned on, then this step is not required for adaptive adjustment, and adaptive adjustment is performed directly to the next bandwidth.

[0054] If the current communication link is adaptively adjusted and still does not meet the call requirements, it will automatically switch to the next communication link for adaptive adjustment in the same way as above. The adaptive adjustment steps and sequence between different frequency bands are the same as those between the same frequency bands, and will not be repeated here. If the communication link still does not meet the call quality requirements, it will continue to automatically switch to the next frequency band until the call quality requirements are met. Figure 5 is a schematic diagram of a multi-channel communication link of a cellular communication network in an embodiment of the present invention. Figure 5As shown, including channels 1 to 8, if the adaptive adjustment of channel 1 does not meet the call quality requirements, it will automatically switch to the next channel 2 for adaptive adjustment; if channel 2 meets the call quality requirements, the adaptive adjustment ends; if it still does not meet the call quality requirements, it will continue to switch to the next channel until all channels of the terminal device are adaptively adjusted. All channel frequency bands of the terminal device can support wireless communication and base stations.

[0055] If the adaptively adjusted communication link meets the preset communication quality requirements, the process ends; if the call requirements are not met, it can also switch to the satellite communication network to further ensure the call quality.

[0056] In an implementation scenario of the present embodiment, after adaptively adjusting the parameters of the communication link of the cellular communication network, it also includes: obtaining second communication quality information of the adjusted cellular communication network; determining whether the second communication quality information meets the preset communication quality requirements; if the second communication quality information does not meet the preset communication quality requirements, switching the current communication link of the target terminal to a satellite communication network, wherein the target terminal is configured with a cellular communication network and a satellite communication network.

[0057] If the terminal device can meet the call quality requirements during the above adaptive adjustment process, the adaptive adjustment is completed and the process ends; if the call quality requirements are still not met after all communication links are adjusted, the terminal device adaptively switches to satellite communication, and the user uses the satellite communication network to ensure the call quality. The satellite used by the satellite communication network can be Beidou satellites, or other satellites such as GPS, GLONASS, Galileo, etc. For example, when the terminal device adaptively adjusts the frequency bands that all base stations can support, and its signal quality still cannot meet the requirements, the terminal device automatically switches to satellite communication.

[0058] Optionally, in the scheme of this implementation scenario, after switching the current communication network of the target terminal to the satellite communication network, it also includes: periodically connecting to the cellular communication network and obtaining current communication quality information of the cellular communication network; determining whether the current communication quality information meets the preset communication quality requirements; if the current communication quality information meets the preset communication quality requirements, switching the current communication network of the target terminal to the cellular communication network.

[0059] When the terminal device switches to the satellite communication network or makes a satellite call, it intermittently connects to the communication network to see if it meets the call quality requirements. If it does not meet the call quality requirements, it continues to conduct satellite communication; if it can meet the normal network call quality requirements, it switches to normal network communication and the process ends. When making intermittent connections during satellite communication, the time can be set to 20s or 30s each time. When making satellite communications, the mobile phone adaptively intermittently connects to the network communication to see if it can be connected and whether the call quality can meet the requirements. If the call quality requirements can be met, the terminal device automatically switches to the wireless network communication and the process ends; if the call quality requirements cannot be met, satellite communication continues. The satellite communication hardware path can be shared with the radio frequency path, or a separate path can be designed and used separately. The satellite communication chip of this embodiment can be integrated in the chip of the cellular communication network, or a separate chip can be used.

[0060] When the adaptive adjustment between the normal communication links fails to meet the requirements, the terminal equipment automatically switches to satellite communication. Because the cost of satellite communication is still relatively expensive, the terminal equipment intermittently connects to the wireless communication network during satellite communication. When it detects that the wireless communication network meets the call requirements, it automatically switches to wireless network communication.

[0061] The solution of this embodiment provides a method for adjusting a communication link. Figure 6 It is an implementation flow chart in an embodiment of the present invention, including: obtaining call quality information of the current cellular communication network; judging whether the signal strength value of the current communication link exceeds the preset value range according to the call quality information; if so, the mobile phone adaptively adjusts the communication link to meet the call requirements; if not, the mobile phone automatically switches to satellite communication, and intermittently connects to the cellular communication network to see whether the call quality requirements are met. If so, switch to a normal cellular communication network; if not, continue to reside in the satellite communication network to ensure smooth mobile phone communication.

[0062] The communication link adjustment method provided in this embodiment can be applied to scenarios where the mobile phone network connection signal is poor, mobile phones and other terminal devices automatically adjust the link, and switch from mobile cellular networks to satellite communications.
