Based on the hardware structure of the mobile terminal, the invention provides various embodiments of the method.

First embodiment

Fig. 3 is a basic flowchart of an antenna switching control method provided in this embodiment, where the antenna switching control method includes:

s301, whether antenna switching is completed or not is detected, and the antenna switching is used for re-determining the communication relation among at least three groups of antennas, the main receiving and transmitting channel and the auxiliary receiving channel, so that new main antennas, auxiliary antennas and idle antennas are selected.

In the embodiment of the present invention, the antenna switching means that the main antenna is switched, for example, the terminal includes 3 sets of antennas Ant0, Ant1, and Ant2, in a time period from t0 to t1 (not including time period t1), the antenna Ant0 is used as the main antenna, the antenna Ant1 is used as the auxiliary antenna, and the antenna Ant2 is used as the idle antenna, at time period t1, Signal quality parameters of the antennas Ant0, Ant1, and Ant2 change due to a change in a user holding the terminal, a terminal placement state, and the like, and the following description takes a Signal quality parameter as RSSI (Received Signal Strength Indication) as an example, for example, Signal Strength values of the antennas Ant0, Ant1, and Ant2 become: RSSI (Ant0, t1) — 98dbm, RSSI (Ant1, t1) — 90dbm, RSSI (Ant2, t1) — 106dbm, RSSI of antenna Ant1 is 8dbm greater than RSSI of antenna Ant0, antenna switching is performed and completed at time t2, after switching, antenna Ant1 is used as a main antenna, antenna Ant0 is used as an auxiliary antenna, antenna Ant2 is used as an idle antenna, and the time difference between t2 and t1 is in the order of milliseconds, for example, t2-t1 is 0.5 ms.

S302, when the fact that the antenna switching is completed is detected, starting a first hysteresis device, wherein hysteresis parameter values of the first hysteresis device are matched with communication quality parameters of a main antenna of the multi-antenna terminal during the antenna switching;

based on the above description, the first hysteresis device is activated at time t2, and the first hysteresis device and the second hysteresis device referred to below function to disable the antenna switching function during operation, and antenna switching is not performed even if the RSSI of each antenna satisfies the antenna switching condition; the implementation mode comprises the implementation mode of pure software, the implementation mode of pure hardware and the implementation mode of combination of software and hardware, the pure software can be realized by programming through a computer program, the pure hardware mode can be realized by adding a special timer in the terminal, and the combination of software and hardware calls the timer in the terminal through software to realize the timing function.

In this embodiment, the hysteresis parameter value of the first hysteresis device has different values in different scenarios, and specifically, the hysteresis duration of the first hysteresis device is related to the communication quality parameter of the main antenna after the previous antenna switching, for example, when the communication quality parameter of the main antenna represents that the signal of the main antenna is strong, the hysteresis duration is longer, the next switching is later, when the communication quality parameter of the main antenna represents that the signal of the main antenna is poor, the hysteresis duration is shorter, the next switching is earlier, so that the individual requirements of different signal qualities of the multi-antenna terminal on the antenna switching are taken into account, and in order to take account of different signal qualities, the embodiment may configure different hysteresis parameter values for different signal qualities.

Since the hysteresis parameter value of a hysteresis device such as a timer cannot be changed after the hysteresis device is started, in order to ensure the normal and accurate operation of the hysteresis device, the configuration process of the first hysteresis device needs to be completed before the first hysteresis device is started, as shown in fig. 4, the method specifically includes the following steps:

s401, acquiring communication quality parameters of a main antenna when the multi-antenna terminal is switched over;

different transmission scenes have different consideration points for different communication quality parameters, for example, when it is determined that the current scene type of the multi-antenna terminal for communication transmission is an uplink transmission scene, the maximum transmission power ratio, the minimum transmission power and the channel estimation parameter of the main antenna are used as main indexes for balancing the uplink signal quality, and the communication quality parameters as the main antenna can better represent the communication quality. Then it is. At this time, obtaining the communication quality parameter of the main antenna when the multi-antenna terminal switches the antenna comprises:

Bearing the assumption that the communication quality parameter is the RSSI of the main antenna, and since the switching rule is determined, the antenna with the largest RSSI is selected as the main antenna, so that at time t1, it can be confirmed that the antenna Ant1 will be the main antenna after switching; then, at this time, the communication quality parameter acquired in this step S401 is RSSI (Ant1, t1) — 90 dbm.

In other embodiments of the present invention, the communication quality parameter may include two or more parameters, for example, bit error rate, signal-to-noise ratio and RSSI, or may include the maximum transmission power ratio in the uplink parameter and RSSI in the downlink parameter.

S402, determining a hysteresis parameter value matched with the communication quality parameter of the main antenna when the multi-antenna terminal is switched at the current antenna according to a preset mapping relation between the communication quality parameter and the hysteresis parameter value;

the mapping relationship may be stored in a text or table manner, and now, for example, the communication quality parameter is RSSI, and the mapping relationship is stored in a table manner, in some embodiments, the mapping relationship is shown in table 1 below:

TABLE 1

In table 1, different RSSI ranges correspond to different hysteresis parameter values, and it can be seen from table 1 that the duration of the hysteresis parameter value is much longer than the antenna switching time, so that multiple times of antenna switching can be avoided within the hysteresis time period, and the power consumption is reduced.

For example, if the communication quality parameter is RSSI (Ant1, t1) — 90dbm, then the corresponding hysteresis parameter value is 8 seconds.

In this embodiment, the mapping relationship may be configured as shown in fig. 9, a user may select a system configuration or a manual configuration according to needs, the system configuration is configured by the system, and the manual configuration may require the user to set hysteresis parameter values corresponding to each RSSI range.

When the communication quality parameters include a plurality of communication quality parameters, a weighting mode can be adopted, and a final hysteresis parameter value can be obtained by performing weight addition calculation according to hysteresis parameter values corresponding to the communication quality parameters, or a final hysteresis parameter value can be obtained by directly performing weight addition calculation on hysteresis parameter values corresponding to the communication quality parameters.

S403, configuring a first hysteresis device according to the hysteresis parameter value.

Taking the first hysteresis device as an example of the first timer, in this case, configuring the first hysteresis device according to the hysteresis parameter value includes: determining a time value corresponding to the hysteresis parameter value; the counting time value of the first timer is set as a time value. Taking the hysteresis parameter value as 8 seconds as an example, the corresponding time value is 8 seconds, and the timing value of the first timer is set to 8 seconds.

Since the communication quality and the hysteresis parameter value have a positive correlation, in other embodiments of the present invention, a calculation formula of the communication quality and the hysteresis parameter value may be set, for example, y is k x + b, where y is the hysteresis parameter value, x is the communication quality parameter, and k is a scaling factor, and is generally kept unchanged. In this case, step S402 is: according to a preset calculation formula, a hysteresis parameter value matched with the communication quality parameter of the main antenna when the multi-antenna terminal is switched over at the current antenna is calculated, for example, x is RSSI, at this time, the hysteresis parameter value y is 0.5 x +55, where the unit of x is dbm, at this time, the communication quality parameter of the main antenna is RSSI (Ant1, t1) — 90dbm, and then the corresponding hysteresis parameter value y is 0.5-90 +55 ═ 10 seconds.

In other embodiments of the present invention, after each antenna switching of the terminal, the communication quality parameter of the main antenna may change, and in order to ensure that the hysteresis parameter value of the first hysteresis device is matched with the communication quality parameter of the main antenna of the terminal in real time, as shown in fig. 5, after step S403, the method further includes the following steps:

s501, after each antenna switching, detecting whether the communication quality parameter of the main antenna of the terminal changes; if the change occurs, executing step S502, and if the change is not sent, returning to continue executing step S501;

taking the example of completing the antenna switching at time t2, the first hysteresis device counts for 8 seconds, and at time t3(t3 is t2+8 seconds) after 8 seconds, after the first hysteresis device finishes counting, the antenna switching algorithm is started, parameter values such as RSSI of each antenna are acquired as target communication parameters of the multi-antenna terminal, so as to determine whether the antenna switching needs to be performed again, for example, the signal strength values of the antennas Ant0, Ant1 and Ant2 are: RSSI (Ant0, t3) — 106dbm, RSSI (Ant1, t3) — 98dbm, RSSI (Ant2, t3) — 90dbm, RSSI of antenna Ant2 greater than RSSI of antenna Ant1 by 8dbm, satisfying the switching condition, performing antenna switching, completing switching at t4(t4 ═ t3+0.1 seconds), after switching, antenna Ant2 as the main antenna, antenna Ant1 as the auxiliary antenna, and antenna Ant0 as the idle antenna. At this time, since the RSSI of the main antenna is-90 dbm at the time t2 and the time t4, no change occurs, and the step S501 is returned to be continuously executed;

taking the example of completing the antenna switching at time t4, the first hysteresis device counts for 8 seconds, and at time t5(t5 is t4+8 seconds) after 8 seconds, after the first hysteresis device finishes counting, the antenna switching algorithm is started, parameter values such as RSSI of each antenna are acquired as target communication parameters of the multi-antenna terminal, so as to determine whether the antenna switching needs to be performed again, for example, the signal strength values of the antennas Ant0, Ant1 and Ant2 are: RSSI (Ant0, t5) — 98dbm, RSSI (Ant1, t5) — 104dbm, RSSI (Ant2, t5) — 108dbm, RSSI of antenna Ant0 greater than RSSI of antenna Ant1 by 6dbm, satisfying the switching condition, performing antenna switching, completing switching at t6(t6 ═ t5+0.1 seconds), after switching, antenna Ant0 as the main antenna, antenna Ant1 as the auxiliary antenna, and antenna Ant2 as the idle antenna. At this time, since the RSSI of the main antenna is-90 dbm at time t4 and-98 dbm at time t6, the change occurs, and the step S502 is continuously executed;

s502, searching a new hysteresis parameter value matched with the new main antenna communication quality parameter;

in table 1, the hysteresis parameter value corresponding to-98 dbm is searched for 6 seconds;

s503, configuring a first hysteresis device according to the new hysteresis parameter value.

At this time, the first hysteresis device is configured according to the new hysteresis parameter value, specifically, the timing value of the first timer is set to 6 seconds.

And S303, when the timing of the first hysteresis device is finished, acquiring a target communication parameter of the multi-antenna terminal to judge whether antenna switching needs to be carried out again, wherein the target communication parameter is used for representing the performance of the antenna.

The first hysteresis device is used for timing for 8 seconds, and after 8 seconds, at the time point of t3(t3 is t2+8 seconds), the first hysteresis device is used for timing completion, an antenna switching algorithm is started, parameter values such as RSSI (received signal strength indicator) of each antenna are obtained to be used as target communication parameters of the multi-antenna terminal, so as to judge whether antenna switching needs to be carried out again, for example, the signal strength values of the antennas Ant0, Ant1 and Ant2 are: RSSI (Ant0, t3) — 106dbm, RSSI (Ant1, t3) — 98dbm, RSSI (Ant2, t3) — 90dbm, RSSI of antenna Ant2 greater than RSSI of antenna Ant1 by 8dbm, satisfying the switching condition, performing antenna switching, after switching, antenna Ant2 as the main antenna, antenna Ant1 as the auxiliary antenna, and antenna Ant0 as the idle antenna.

The embodiment aims at the defect that the power consumption is large due to the fact that the antenna switching algorithm is frequently operated by the existing multi-antenna terminal to conduct antenna switching, the hysteresis device with a certain hysteresis time is arranged, after the antenna switching is successfully conducted for one time, the hysteresis device is started, the antenna switching algorithm is not conducted any more within the hysteresis time of the hysteresis device even if the signal parameters of each antenna meet the antenna switching condition, and whether the antenna switching needs to be conducted or not is judged again only after the hysteresis time of the hysteresis device is ended, so that the problem that the power consumption is large due to the fact that the antenna switching is conducted by the existing multi-antenna terminal when the antenna switching algorithm is frequently operated is solved, and the ping-pong effect is controlled in the; meanwhile, the lag time of the lag device is related to the communication quality parameter of the main antenna after the previous antenna switching, for example, when the communication quality parameter of the main antenna represents that the signal of the main antenna is strong, the lag time is longer, the next switching is later, when the communication quality parameter of the main antenna represents that the signal of the main antenna is poor, the lag time is shorter, the next switching is earlier, so that the individual requirements of different communication qualities of the multi-antenna terminal on the antenna switching are considered, and the use experience of a user is further enhanced.

Second embodiment

Fig. 6 is a detailed flowchart of an antenna switching control method according to a second embodiment of the present invention, where the antenna switching control method includes:

s601, configuring a hysteresis strategy, a mapping relation and working parameters.

As shown in fig. 8, the hysteresis strategy includes three modes, i.e., a communication quality parameter adaptive mode, an operating parameter adaptive mode and a non-hysteresis mode; when the configured hysteresis policy is the communication quality parameter adaptive mode, the first hysteresis device is enabled, when the configured hysteresis policy is the working parameter adaptive mode, the second hysteresis device is enabled, when the configured hysteresis policy is the non-hysteresis mode, the first hysteresis device and the second hysteresis device are disabled, and the user can select from the interface shown in fig. 8.

The configuration interface of the mapping relationship is shown in fig. 9, which has already been described above and is not described again.

The working parameters include state parameters such as an operating state inside the terminal and scene parameters such as a working scene outside the terminal, and a configuration interface of the working parameters is as shown in fig. 10.

The operation of the antenna switching algorithm can optimize the antenna signal to reduce the power consumption of the device, but the switching algorithm itself will bring certain power consumption, so how to optimize the two is a problem that needs to be considered in a critical way, and the hysteresis parameter is configured according to the communication quality parameter and the like during switching, only the terminal operation parameter is considered, and the user behavior factor is not considered, so that a second hysteresis device is provided.

The scheme for configuring the second hysteresis device based on the state parameters considers the dynamic balance of the power consumption of the terminal under different working states (namely the operation of the user on the terminal), and configures different hysteresis parameters N for different states; for example: assuming that the antenna signal strength and the like have a large influence on the power consumption of the terminal in a call state and the power consumption caused by the switching algorithm is negligible, at this time, the minimum hysteresis parameter (such as 3 seconds) can be used to ensure that the signal strength of the main antenna is maximum and reduce the power consumption, assuming that the antenna signal strength and the like have a small influence on the power consumption of the terminal in a standby state and the power consumption caused by the switching algorithm is large, at this time, the large hysteresis parameter (such as 10 seconds) can be used to reduce the power consumption caused by frequently triggering the switching algorithm; on the basis, after one switching, the current working state is detected, and the corresponding hysteresis parameter is determined, so that each working state has lower power consumption.

The scheme for configuring the second hysteresis device based on the environmental parameters considers the dynamic balance of the power consumption of the terminal under different working scenes (namely the use habits of users on the terminal), and configures different hysteresis parameters for different scenes; for example: supposing that in a scenario where a user needs to use a terminal frequently (for example, the user is determined to be in a company according to a time period, a location, and the like), the influence of the antenna signal strength and the like on the power consumption of the terminal is large, and the power consumption caused by a switching algorithm is negligible, at this time, a minimum hysteresis parameter (N ═ 3 seconds) can be used to ensure that the signal strength of a main antenna is maximum, and the power consumption is reduced, and supposing that in a scenario where the user does not need to use a mobile phone frequently (for example, according to a time end), the influence of the antenna signal strength and the like on the power consumption of the terminal is small, and the power consumption caused by the switching algorithm is large, at this time, a large hysteresis parameter (; on the basis, after one switching, the current working scene is detected, and the corresponding hysteresis parameter is determined, so that each scene has lower power consumption.

S602, when the antenna switching is triggered, the hysteresis strategy is read, and a first hysteresis device and a second hysteresis device are configured.

When the antenna switching is triggered, the maximum RSSI among the RSSI of each antenna is obtained as the RSSI of the main antenna after the switching, for example, assuming that the RSSI of each antenna satisfies the antenna switching condition at time t1, the antenna switching is triggered, and at this time, the hysteresis policy is read, and the first hysteresis device and the second hysteresis device are configured.

In this embodiment, after triggering the antenna switching, the following steps are performed:

acquiring a hysteresis strategy;

The maximum RSSI of the RSSI of each antenna is obtained as the RSSI of the main antenna after switching, for example, the RSSI of the main antenna after switching is-90 dbm, the RSSI is searched in table 1, the corresponding hysteresis parameter value is determined to be 8 seconds, and the first hysteresis device is configured to delay for 8 seconds.

Reading the configuration result of the working parameters, and if the configuration is that the state parameters are effective, executing the following steps:

acquiring the running state of the multi-antenna terminal; the running state comprises a call state (single voice, video call and the like based on the mobile network), a data service state (video online playing, data uploading and downloading and the like based on the mobile network), a standby state, a dormant state and the like;

the correspondence between the operating conditions and the hysteresis parameter values may be as shown in table 2 below:

operating state	Hysteresis parameter value	Operating state	Hysteresis parameter value
				State of conversation	3 seconds	Standby state	15 seconds
Data traffic status	4 seconds	Dormant state	60 seconds
				……

TABLE 2

As can be seen from table 2, the dependency degree of the operating state on the signal quality and the hysteresis parameter value have a negative correlation, that is, the larger the dependency degree of the operating state on the signal quality, the smaller the hysteresis parameter value is, so as to ensure the communication quality, and the smaller the dependency degree of the operating state on the signal quality, the larger the hysteresis parameter value is, so as to reduce the power consumption of the device.

For example, if the current operation state of the terminal is the data service state, the hysteresis parameter value corresponding to the operation state is 4 seconds, and then the second hysteresis device is configured according to the hysteresis parameter value.

Reading the configuration result of the working parameters, and if the configuration result is that the environmental parameters are effective, executing the following steps:

acquiring a working scene of the multi-antenna terminal; the working scene comprises working at a company, resting at the company, working at home, resting at home, using a mobile phone by a user, not using the mobile phone by the user and the like;

the method for acquiring the working scene is various, for example, the method is determined by combining the terminal position and the time period, for example, when the terminal is determined to be in the company through GPS positioning and the current time period is 9:00-12:00, the working scene is judged to be on work at the company, when the terminal is determined to be in the company through GPS positioning and the current time period is 12:00-14:00, the working scene is judged to be at rest at the company, when the terminal is determined to be at home through GPS positioning and the current time period is 9:00-12:00, the working scene is judged to be at home for work, and when the terminal is determined to be at home through GPS positioning and the current time period is 19:00-8:00, the working scene is judged to be at rest at home.

The method can also be used for determining the illumination intensity, if the illumination sensor of the terminal detects that the ambient illumination intensity is less than 0.2Ix, the terminal is considered to be in a dark scene, and the user does not use the mobile phone, and if the illumination sensor of the terminal detects that the ambient illumination intensity is greater than 12.56Ix and less than 550Ix, the terminal is considered to be in a normal indoor scene, and the user uses the mobile phone. Whether the user uses the mobile phone or not can be judged in other modes, such as instantaneous acceleration of the terminal, distance between the terminal and the user, grip strength of the user detected by the pressure sensor and the like, and further description is omitted.

Determining a hysteresis parameter value matched with the operation state of the multi-antenna terminal according to the corresponding relation between a preset working scene and the hysteresis parameter value;

the correspondence between the working scenario and the hysteresis parameter value can be shown in table 3 below:

working scene	Hysteresis parameter value	Working scene	Hysteresis parameter value
				Company working	3 seconds	Rest at company	15 seconds
At home working	4 seconds	Rest at home	60 seconds
				The user is using the mobile phone	8 seconds	User does not use mobile phone	100 seconds
……

TABLE 3

As can be seen from table 3, the degree of dependence of the operating scene on the signal quality and the hysteresis parameter value have a negative correlation, that is, the larger the degree of dependence of the operating scene on the signal quality is, the smaller the hysteresis parameter value is, so as to ensure the communication quality, and the smaller the degree of dependence of the operating scene on the signal quality is, the larger the hysteresis parameter value is, so as to reduce the power consumption of the device.

For example, if the current working scenario of the terminal is at home for rest, the corresponding hysteresis parameter value is 60 seconds, and then the second hysteresis device is configured according to the hysteresis parameter value.

In the present embodiment, it is assumed that the operating parameter is configured such that the operating state is active, and at time t1, the operating state is a talk state, at which time the second hysteresis device delays by 3 seconds.

And S603, switching the antenna, and determining a subsequent flow according to a hysteresis strategy.

And S605, when the hysteresis strategy is in the working parameter self-adapting mode, starting the second hysteresis device, and executing the step S607 after delaying for 3 seconds.

S606, when the hysteresis policy is not hysteresis, the first hysteresis device and the second hysteresis device are disabled, and step S607 is directly executed.
