The antenna switching condition is a condition for triggering the current antenna to switch, and specifically includes: selecting two groups of antennas for working from all antennas on a terminal, and determining a main antenna and an auxiliary antenna from the two groups of antennas; specifically, the time sequences of selecting two sets of antennas for working and determining the main antenna and the auxiliary antenna are not necessarily in sequence, the two antennas can be generally performed simultaneously, and after the two sets of antennas for working are determined, the main antenna and the auxiliary antenna are determined simultaneously.
Specifically, the antenna switching condition, in this embodiment, may include: the working state parameter of the current main antenna and/or the auxiliary antenna is smaller than the corresponding threshold value; or the deterioration amount of the current working state parameter of the main antenna and/or the auxiliary antenna in the preset time is larger than the corresponding change threshold. That is, for the antenna switching condition, it can be roughly divided into two types, one of which is that the specific value of the operating state parameter of the antenna is smaller than the corresponding threshold value. The threshold value here generally means that the terminal can normally perform communication without causing excessive power consumption, and there is no real experience of hard injury in the user communication process. In other words, the threshold value represents the tolerance of the user to the terminal. Generally speaking, a user may feel uncomfortable when the power of the terminal is too fast, the network connection is not smooth, and the communication is interrupted, which may cause poor user experience, and may be caused by too low working state parameters of a certain antenna in the current working state. The condition whether the antenna switching can be triggered after the operating state parameter is lower than the threshold value may specifically include which group of antennas in the operating state is used as a reference. When comparing the threshold values, only one antenna of the main antenna and the auxiliary antenna is referred to, and the working state parameter of any antenna is lower than the threshold value, which means that the antenna switching condition is satisfied, or the two antennas are referred to at the same time, and the working state parameter of both antennas is lower than the threshold value, which means that the antenna switching condition is satisfied. It is worth mentioning that the working state parameters of the antenna are various, and the threshold values adopted by referring to different working state parameters are generally different; the states of the terminals are different, and the requirements for the working state parameters are different, for example, when the terminals are in an idle state, there is no use requirement, there is no need to pursue an excessively high working state parameter, and the threshold value at this time may be slightly lower, while when the terminals are in a use state, for example, when the terminals are in a call and are on the internet, it is necessary to maintain good communication quality, and the threshold value at this time may be slightly higher, so as to ensure that the communication quality of the terminals is always at a higher level. In addition, since the operating states of the main antenna and the auxiliary antenna are different, the requirements for the operating state parameters between the main antenna and the auxiliary antenna are not necessarily consistent, for example, the operating state parameters for the main antenna should be higher than those for the auxiliary antenna, that is, the operating state parameters for the main antenna and the auxiliary antenna may also be set to be different.
Secondly, the working state parameters of the current main antenna and/or the auxiliary antenna are suddenly deteriorated in the preset time. The deterioration is that the operating state parameter becomes worse and deteriorates sharply, and the most probable reason may be that the user holds the antenna in the operating state to cause a block, which may cause the operating state parameter of the corresponding antenna to deteriorate greatly in a short time. Correspondingly, due to different types of the working state parameters of the antenna, the corresponding preset time and the corresponding change threshold value can be different; the states of the terminals are different, and the corresponding preset time and the corresponding change threshold value can also be different; because the working states of the main antenna and the auxiliary antenna are different, the requirements on the working state parameters between the main antenna and the auxiliary antenna are not necessarily consistent, and the corresponding preset time and the corresponding change threshold value can also be different.
In addition, in this embodiment, in order to maintain the stability of the terminal, the frequency of switching the antenna is reduced within a possible range, when it is determined whether the antenna switching condition is satisfied, the antenna switching condition may be detected multiple times within a certain time, and whether to perform antenna switching is determined according to the result of the multiple times of detection; for example, if the working state parameter of the main antenna is found to be lower than the threshold value for the first time, and the working state parameter of the main antenna returns to be higher than the threshold value within 1s, the embarrassment that the main antenna is switched and then the main antenna is switched back again can be avoided by multiple times of judgment. Or, a certain protection time may be set after the switching to prevent the antenna from being switched again, for example, when the antenna of the terminal is set to be not switched again within 5s after being switched once, the ping-pong effect may be effectively prevented from occurring.
Specifically, the polling of the operating state parameters of each group of antennas by the baseband processor when the antennas are in the operating state may include: an antenna switching control module in the baseband processor adjusts the switch selection circuit of the N-selection 2 to sequentially communicate each group of antennas with the main transceiving passage; and acquiring working state parameters of each group of antennas in a working state through a diagnosis service module or a radio frequency driving module in the baseband processor. When polling the operating state parameters of each antenna, it is first ensured that the detected antenna needs to be in an operating state, that is, the antenna is connected to the primary transceiving channel or the secondary receiving channel. Because the auxiliary receiving channel only has the function of receiving signals, each antenna is generally accessed to the main receiving and transmitting channel during polling, and the normal communication of the terminal can be ensured. After access, the operational state parameters of the accessed antenna can be obtained through a diagnostic service module (diag) or a Radio Frequency (RF) driver module. In this embodiment, the operating state parameters may include two categories, namely, an uplink parameter and a downlink parameter, where the uplink parameter is related to an uplink channel of the terminal, and the main reference index may include a magnitude of the transmit power of the terminal, or a ratio of the uplink to the maximum transmit power in a unit time. The larger the transmission power is, the worse the communication quality of the uplink signal is, and the communication quality is poor, so that the larger the transmission power is required to ensure communication; similarly, the larger the ratio of the maximum transmission power reached by the uplink in the unit time, the worse the communication quality of the uplink signal. The downlink parameters are related to a downlink channel of the terminal, and may mainly include parameters such as signal strength, signal quality, and the like. Specifically, the specific reference signal strength and signal quality are different according to different network systems, such as a GSM network, a WCDMA/TD-SCDMA network, and an FDD-LTE/TDD-LTE network.
The diagnostic service module or the rf driver module is a component of the baseband processor, and can collect the operating parameters of each antenna in real time, such as the received signal strength, the transmitting power, and other information, and generate a log (log). When the working state parameters of the antenna are polled, the working state parameters of the corresponding antenna can be obtained by adopting any one of the diagnosis service module or the radio frequency driving module. According to different network standards, the frequency of the diagnostic service module or the radio frequency driving module for collecting the working state parameters is different, for example, the collection interval of TD-SCDMA is generally 40ms, and the LTE is 320 ms.
In S402, the same type of operating state parameters of each group of antennas are compared, and a comparison result is generated. Comparing the same type of working state parameters of each group of antennas, it is a process of determining the communication quality relationship among the antennas in each group, and the purpose of antenna switching in this embodiment is to find an antenna with better communication quality as a working antenna, where the communication quality of the main antenna should be the best among all antennas. For comparison of the same type of operating state parameters of each group of antennas, it is obvious that comparison among the same type of operating state parameters should be ensured, and different types of operating state parameters generally cannot be compared; specifically, during the comparison, each group of antennas may compare only one working state parameter, or may compare with reference to multiple working state parameters, and the multiple working state parameters may only refer to the working state parameters of the uplink channel, or only refer to the working state parameters of the downlink channel, or comprehensively consider the working state parameters of the uplink channel and the working state parameters of the downlink channel, which are feasible in this embodiment.
In S403, a corresponding switching command is generated based on the comparison result. The switching instruction at least comprises a target main antenna and a target auxiliary antenna to be switched, wherein the working state parameter of the target main antenna is not weaker than the working state parameters of other antennas, which indicates that the working state parameter of the target main antenna is the best of all the antennas, so that lower power consumption and better user experience can be ensured.
Specifically, in this embodiment, comparing the operating state parameters of the same type of each group of antennas and generating the comparison result may include: and comparing the working state parameters of the same type of each group of antennas through the diagnosis service module or the radio frequency driving module, and generating a comparison result. In the embodiment, the comparison of the working state parameters is directly performed by a diagnostic service module or a radio frequency driving module in the baseband processor, that is, a module for acquiring the working state parameters, and a comparison result is generated. Accordingly, in this case, generating the corresponding switching instruction based on the comparison result may include: and the antenna switching control module determines the target main antenna and the target auxiliary antenna according to the comparison result and generates a corresponding switching instruction. After the diagnosis service module or the radio frequency driving module generates the comparison result, the comparison result can be fed back to the antenna switching control module, and the antenna switching control module generates a specific switching instruction; the switching instruction can be fed back to a specific circuit through the HAL simulation hardware layer, namely the N-to-2 switch selection circuit, and the gating relation of the switch selection circuit is adjusted, so that the switch selection circuit can enable the corresponding antenna to be communicated with the main transceiving passage or the auxiliary receiving passage, namely the target main antenna is communicated with the main transceiving passage, and the target auxiliary antenna is communicated with the auxiliary receiving passage.
Specifically, in this embodiment, comparing the operating state parameters of the same type of each group of antennas and generating the comparison result may further include: the diagnostic service module or the radio frequency driving module sends the acquired working state parameters to the antenna switching control module in real time; the antenna switching control module compares the working state parameters of each group of antennas and generates a comparison result. In the embodiment, the diagnostic service module or the radio frequency driving module, that is, the module for acquiring the working state parameters of the antenna, sends the acquired corresponding working state parameters of the antenna to the antenna switching control module in real time, and the antenna switching control module performs summarization and comparison to generate a comparison result. For the diagnosis service module or the radio frequency driving module, the comparison process is transferred to the antenna switching control module, so that the operation burden of the diagnosis service module or the radio frequency driving module is reduced, and the acquisition of the working state parameters of the antenna can be focused. Accordingly, in this case, generating the corresponding switching instruction based on the comparison result may include: and the antenna switching control module determines the target main antenna and the target auxiliary antenna according to the comparison result and generates a corresponding switching instruction. After the diagnosis service module or the radio frequency driving module generates the comparison result, the comparison result can be fed back to the antenna switching control module, and the antenna switching control module generates a specific switching instruction; the switching instruction can be fed back to a specific circuit through the HAL simulation hardware layer, namely the N-to-2 switch selection circuit, and the gating relation of the switch selection circuit is adjusted, so that the switch selection circuit can enable the corresponding antenna to be communicated with the main transceiving passage or the auxiliary receiving passage, namely the target main antenna is communicated with the main transceiving passage, and the target auxiliary antenna is communicated with the auxiliary receiving passage.
Specifically, in this embodiment, comparing the operating state parameters of the same type of each group of antennas and generating the comparison result may further include: the antenna switching control module acquires working state parameters of each group of antennas from the diagnosis service module or the radio frequency driving module according to a preset time interval; the antenna switching control module compares the working state parameters of each group of antennas and generates a comparison result. In this embodiment, the antenna switching control module actively obtains the operating state parameters of the antennas from the diagnostic service module or the radio frequency driving module according to a certain preset time interval, so that the diagnostic service module or the radio frequency driving module can obtain the operating state parameters of a certain number of antennas at a time, and the operating power consumption of the antenna switching control module is reduced to a certain extent. Accordingly, in this case, generating the corresponding switching instruction based on the comparison result may include: and the antenna switching control module determines the target main antenna and the target auxiliary antenna according to the comparison result and generates a corresponding switching instruction.
