Technical Field

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at … …" or "at … …" or "in response to a determination" depending on the context.

Before describing the antenna tuning method provided in the present disclosure, an underlying design of a multi-card terminal in the related art will be described.

Current multi-card terminals mainly include two designs, dual card bi-pass (DSDA, dual SIM Dual Active) and dual card bi-standby (DSDS, dual SIM Dual Standby). Wherein, double-card double-pass means that two SIM cards arranged by the terminal can be connected to two networks at the same time. When a user establishes a call using one of the SIM cards, another call may be established using the other SIM card. And double-card double-standby means that two SIM cards arranged by the terminal can wait for telephone access at the same time, but if one SIM card has established a call, the other SIM card cannot be used.

In the related art, the underlying design for DSDA mode is mainly divided into two types:

the first is completely double-pass, the receiving antennas and the transmitting antennas of the two SIM cards arranged on the terminal are completely independent, and the schematic diagram of the transmitting antennas is shown in figure 1. In this case, the tuning of the terminal to the transmitting antenna is also two independent sets of logic, which do not affect each other. Commonly referred to as FC (Full Concurrency).

The second is a partial double pass, the receiving antennas of the two SIM cards arranged in the terminal are completely independent, and the transmitting antennas share the same path, i.e. share the same transmitting antenna, as shown in fig. 2. Commonly referred to as TS (Tx-Sharing), transmit front-end path Sharing).

For the TS DSDA mode, since two SIM cards share the same transmitting antenna, in the related art, a fixed tuning parameter is configured for the transmitting antenna, where the fixed tuning parameter is configured based on the principle of balancing the transmitting performance of the two SIM cards. Therefore, the emission performance of both SIM cards is not optimal.

When the signal receiving power corresponding to the signals on the two SIM cards is equivalent, the fixed antenna tuning method can better consider the transmitting performance of the two SIM cards. However, when the signal receiving power corresponding to the signal on one of the SIM cards is weak, the transmitting performance of the SIM card will be under a greater test.

In order to solve the above technical problems, embodiments of the present disclosure provide the following antenna tuning method, apparatus, storage medium, and electronic device. The terminal can determine target tuning parameter values based on the signal values of the SIM cards measured in real time, and tune the Tuner parameter value of the shared transmitting antenna based on the determined target tuning parameter values, so that the effect of dynamically inclining to the transmitting capacity of the SIM card with weak network signal quality and ensuring the stability and fluency of the service of the SIM cards is realized.

The antenna tuning method according to the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

Fig. 3 is a flow chart of an antenna tuning method according to an exemplary embodiment of the present disclosure. As shown in fig. 3, the method of the exemplary embodiment may be applied to a terminal, including but not limited to a mobile phone, ipad, etc. The terminal is provided with a plurality of SIM cards, and the plurality of SIM cards share the same transmitting antenna. Specifically, the method of this exemplary embodiment may be performed by an operating system of the above terminal, where the operating system includes, but is not limited to, an android system, an IOS system, and the like. As shown in fig. 3, the exemplary embodiment method may include the steps of:

in step 300, signal quality of the network where the plurality of SIM cards are respectively located is measured, so as to obtain at least one signal value corresponding to each SIM card.

In the embodiment of the present disclosure, the terminal may be provided with two SIM cards, or may also be provided with more than two SIM cards, which is not limited in this disclosure. For convenience of description, the description of the following embodiments will be made with the terminal provided with two SIM cards.

In the TS DSDA mode, the first SIM card and the second SIM card may be connected to both networks at the same time. In popular terms, when a user uses a first SIM card to make a call, another call may be made simultaneously using a second SIM card, or a network game may be made simultaneously using the second SIM card. In this mode, the first SIM card and the second SIM card share the same transmitting path, that is, share the same transmitting antenna, and transmit signals in a time-sharing transmission manner.

For example, the first SIM card may use the shared transmitting antenna to transmit a signal with a standard of NR (New Radio, 5G) and a frequency Band of Band N1. The second SIM card may use the shared transmitting antenna to transmit signals with a standard NR and a frequency Band of Band N28. The above NR Band N1 is the network where the first SIM card is located, and the above NR Band N28 is the network where the second SIM card is located.

The operating system of the terminal can measure and acquire the signal quality of the network NR Band N1 where the first SIM card is located and the signal quality of the network NR Band N28 where the second SIM card is located, so as to obtain at least one signal value corresponding to each SIM card.

For example, the operating system of the terminal may measure and obtain a signal value of the network where the first SIM card is located, which is assumed to be-110 db, and a signal value of the network where the second SIM card is located, which is assumed to be-90 db.

For another example, the operating system of the terminal may measure and acquire a plurality of signal values of the network where the first SIM card is located, which are assumed to be-100 db and 120db, and the signal value of the network where the second SIM card is located, which are assumed to be-70 db and-90 db.

It should be noted that, the network where the first SIM card and the second SIM card are located may be changed based on an actual network environment, and in the above embodiment, the network where the first SIM card is located is NR Band N1, and the description where the network where the second SIM card is located is NR Band N28 is only schematic, so that those skilled in the art may better understand the technical solutions of the embodiments of the present disclosure.

In step 302, a target signal value corresponding to each SIM card is determined based on at least one signal value corresponding to each SIM card.

In an example, if a signal value of the network where each SIM card is located is measured, the signal value is determined to be a target signal value corresponding to the SIM card.

In another example, if a plurality of signal values of a network where one SIM card is located are measured, an average value, a maximum value, or a minimum value of a plurality of signal values corresponding to the one SIM card may be determined as one target signal value corresponding to the one SIM card.

In step 304, a target tuning parameter value for tuning the coordinator Tuner of the transmitting antenna is determined when a plurality of the target signal values satisfy a preset condition.

Before describing the antenna tuning method in this step, it should be first explained that in the TS DSDA mode, a fixed parameter is configured for Tuner of the shared transmitting antenna by default, where the fixed parameter is configured based on a principle that signal transmitting powers corresponding to two SIM cards can be balanced. The antenna tuning method in the step is to tune the fixed parameters based on the signal quality of the network where the two SIM cards are located, which is measured in real time, so as to realize the purpose of dynamically tilting the transmitting capability of the SIM card with weaker network signal quality.

In an alternative example, the preset condition may include: the difference value of any two of the target signal values is larger than a first preset threshold value; or at least two of the plurality of target signal values are less than a second preset threshold.

In the embodiment of the disclosure, when the difference value of the target signal values of the first SIM card and the second SIM card is greater than the first preset threshold, it indicates that the network signal quality of one of the two SIM cards is better and the network signal quality of the other SIM card is worse. At this time, the Tuner of the transmitting antenna can be tuned to enhance the transmitting power of the SIM card with poor network signal quality, so as to ensure the service stability and smoothness of the SIM card. The first preset threshold may be, for example, 10db, or may be 8db, which may be specifically set by the relevant staff based on the actual situation, which is not limited in the present disclosure.

And when the target signal values of the first SIM card and the second SIM card are smaller than the second preset threshold value, the network signal quality of the two SIM cards is poor. At this time, the Tuner of the transmitting antenna can be tuned to enhance the transmitting power of one of the SIM cards, so as to ensure the service stability and smoothness of the SIM card. The second preset threshold may be, for example, -115db, or-118 db, and specifically may be set by the relevant staff based on the actual situation, which is not limited in this disclosure.

In the embodiment of the disclosure, when the target signal values of the first SIM card and the second SIM card meet any of the above conditions, the target tuning parameter value may be determined based on the target signal values of the first SIM card and the second SIM card.

In an alternative example, when the target signal values of the first SIM card and the second SIM card meet any of the above conditions, a first difference value of the target signal values of the first SIM card and the second SIM card may be calculated, and a tuning parameter value corresponding to the first difference value may be taken as the target tuning parameter value.

For example, when the first preset threshold is 10db, the target signal value of the first SIM card is-95 db, and the target signal value of the second SIM card is-106 db, it may be determined that the target signal value of the second SIM card is 11db weaker than the target signal value of the first SIM card and greater than the first preset threshold by 10db. Namely, the target signal values of the two SIM cards meet the preset condition. Thus, a target tuning parameter value for tuning the coordinator Tuner of the transmit antenna may be further determined.

Specifically, since the target signal value of the second SIM card is weaker than the target signal value of the first SIM card by 11db, that is, the first difference is 11db, the terminal operating system needs to increase the transmission power of the second SIM card by 11db by tuning the parameter value of the Tuner of the transmitting antenna. As can be obtained from the foregoing embodiment, the network where the second SIM card is located is NR Band N28, and therefore, the tuning parameter value corresponding to NR Band N28+11db can be determined as the target tuning parameter value.

In another alternative example, after the first difference value is obtained, a second difference value between the first difference value and a preset value may be further calculated, and a tuning parameter value corresponding to the second difference value is taken as the target tuning parameter value. The correspondence between the difference and the tuning parameter value may be preset by a relevant staff based on the simulation result.

For example, when the second preset threshold is-115 db, the target signal value of the first SIM card is-118 db, and the target signal value of the second SIM card is-128 db, it may be first determined that the target signal values of the first SIM card and the second SIM card are both less than the second preset threshold-115 db. Namely, the target signal values of the two SIM cards meet the preset condition. Thus, a target tuning parameter value for tuning the coordinator Tuner of the transmit antenna may be further determined.

Specifically, since the target signal value of the second SIM card is 10db weaker than the target signal value of the first SIM card, that is, the first difference is 10db, at this time, the second difference between the first difference and the preset value may be further calculated. Assuming that the preset value is 3db, the second difference is 7db. Thus, the terminal operating system needs to increase the transmit power of the second SIM card by 7db by tuning the parameter value of Tuner of the transmit antenna. As can be obtained from the foregoing embodiment, the network where the second SIM card is located is NR Band N28, and therefore, the tuning parameter value corresponding to NR Band N28+7db can be determined as the target tuning parameter value.

The above embodiment is explained with the preset value of 3db, but it should be clear that the preset value may be not only 3db, but also other values, which may be specifically set by the relevant staff based on the actual situation.

In step 306, the Tuner is tuned to increase the transmit power of at least one of the plurality of SIM cards based on the target tuning parameter value.

In the embodiment of the disclosure, after the target tuning parameter value is obtained, a parameter value of a Tuner of the transmitting antenna may be configured as the target tuning parameter value.

For example, tuning parameter values corresponding to the above-described nrband n28+11db may be configured to Tuner of the transmit antenna. Or tuning parameter values corresponding to the above-mentioned nrband n28+7db may be configured to Tuner of the transmitting antenna. Thereby increasing the transmit power of the second SIM card.

According to the antenna tuning method provided by the embodiment of the disclosure, at least one signal value corresponding to each SIM card is obtained by measuring the signal quality of the network where the plurality of SIM cards are respectively located. And determining a target signal value corresponding to each SIM card based on at least one signal value corresponding to each SIM card. And when a plurality of target signal values meet a preset condition, determining a target tuning parameter value for tuning a coordinator Tuner of the transmitting antenna. And tuning the Tuner based on the target tuning parameter value to increase the transmitting power of at least one of the plurality of SIM cards. The antenna tuning method provided by the embodiment of the disclosure can dynamically switch the parameter values of Tunner, so that the effect of dynamically inclining to the transmitting capacity of the SIM card with weak network signal quality and ensuring the service stability and fluency of a plurality of SIM cards is realized.

The following describes further some steps of the antenna tuning method described above:

with respect to step 304 described above, in an alternative example, in determining the target tuning parameter value for tuning the coordinator Tuner of the transmit antenna, the following steps may be performed:

In an alternative example, a correspondence table may be acquired and stored in advance in the terminal. The format of the correspondence table may be as shown in table 1 below:

TABLE 1

Tuning parameter values	Difference value
		1	N1+10db，N28-8db
2	N1+11db，N28-9db
		3	N28+6db，N1-4db
4	N28+10db，N1-8db
		5	N28+11db，N1-9db

The corresponding relation table is preconfigured by related staff and stored in the terminal. It should be noted that the correspondence table described above is different when the network signals are different for the same antenna. The embodiment of the present disclosure will be described by taking the above correspondence table corresponding to the case where the network of the first SIM card is NR Band N1 and the network of the second SIM card is NR Band N28 as an example.

Specifically, the contents of table 1 above can be understood as:

When the transmit power of the first SIM card needs to be increased by 10db, the tuning parameter value of Tuner of the transmit antenna may be tuned from a fixed parameter value to 1. When the transmit power of the second SIM card needs to be increased by 6db, the tuning parameter value of Tuner of the transmit antenna may be tuned from a fixed parameter value to 3.

Since the correspondence table is preset by the relevant staff and then stored in the terminal, when the network of the first SIM card is NR Band N1 and the network of the second SIM card is NR Band N28, the maximum tuning capability of the transmitting antenna for both the first SIM card and the second SIM card is preset.

For example, when the network of the first SIM card is NR Band N1 and the network of the second SIM card is NR Band N28, the maximum tuning capability for the first SIM card is 11db and the maximum tuning capability for the second SIM card is 11db, which are obtained from table 1 above. As can be seen from the practical situation, the minimum tuning capability for the first SIM card and the second SIM card is 0, i.e. no tuning is performed.

In an alternative example, tuning may be based on the maximum coordination capacity when the first difference is greater than the maximum coordination capacity. Or may choose not to tune. The setting can be specifically performed by the relevant staff based on actual conditions, and the disclosure is not limited to this.

After understanding the contents in the correspondence table, the foregoing example is followed to describe in detail the antenna tuning method of the present example:

For example, when it is determined that the tuning parameter value corresponding to nrband n28+11db is to be determined as the target tuning parameter value, the operating system of the terminal may determine that the target tuning parameter value is 5 based on the above table 1.

For another example, when it is determined that the tuning parameter value corresponding to nrband n28+10db is to be determined as the target tuning parameter value, the operating system of the terminal may determine that the target tuning parameter value is 4 based on the above table 1.

According to the antenna tuning method provided by the example, the target tuning parameter value can be determined based on the difference value of the target signal values of the two SIM cards, and the parameter value Tunner is dynamically switched based on the target tuning parameter value, so that the purpose of symmetrically inclining to the transmitting capacity of the SIM card with weak network signal quality is achieved, and the service stability and fluency of a plurality of SIM cards are ensured.

In an alternative example, when determining the target tuning parameter value for tuning the coordinator Tuner of the transmitting antenna, it may also be performed based on the following steps:

Determining a first tuning correction value;

As can be seen from the above table 1 together with the actual situation, when the transmitting power of one SIM card is increased by the antenna tuning method according to the embodiment of the present disclosure, the transmitting power of the other SIM card is reduced. And, to a certain extent, the amplitude of the increase of the transmitting power of one SIM card is positively correlated with the amplitude of the decrease of the transmitting power of the other SIM card. Therefore, when the target signal values of the first SIM card and the second SIM card are weak, for example, are about-100 db, the tuning amplitude can be reduced appropriately in order to allow both SIM cards to operate normally.

Specifically, the first tuning correction value may be preset to 5db.

Continuing with the previous example, when the first preset threshold is 10db, the target signal value of the first SIM card is-95 db, and the target signal value of the second SIM card is-106 db, it may be determined that the target signal value of the second SIM card is 11db weaker than the target signal value of the first SIM card, and greater than the first preset threshold by 10db. Namely, the target signal values of the first SIM card and the second SIM card meet the preset conditions. Thus, it may be determined that the first difference of the target signal values of the first and second SIM cards is 11db.

From the foregoing, the first tuning correction value is 5db, and therefore, it can be further determined that the second difference between the first difference 11db and the first tuning correction value 5db is 6db.

Finally, a tuning parameter value 3 corresponding to the second difference value 6db may be determined as the target tuning parameter value based on the above table 1.

It should be noted that the first correspondence relationship and the second correspondence relationship may be the same or different, that is, the second correspondence relationship may be represented by table 1 or other table contents, which is not limited in this disclosure.

According to the antenna tuning method provided by the example, a tuning correction value can be preset, after the first difference value is obtained, a second difference value between the first difference value and the tuning correction value is further calculated, and the second difference value is determined to be the target tuning parameter value, so that the tuning amplitude of the parameter value of the Tuner of the transmitting antenna is reduced, the transmitting power of the second SIM card is enhanced, the transmitting power of the first SIM card is not greatly reduced, and the normal use of networks of two SIM cards is ensured.

In an alternative example, the target tuning parameter value for tuning the coordinator Tuner of the transmitting antenna may be determined when the duration that the plurality of signal values satisfy the preset condition reaches the preset time period.

For example, the target tuning parameter value may be further determined when the duration in which the plurality of target signal values satisfy the preset condition reaches 10 seconds. For another example, the target tuning parameter value may be further determined when the duration in which the plurality of target signal values satisfy the preset condition reaches 8 seconds. The present disclosure is not limited in this regard.

According to the antenna tuning method, when the duration that the target signal values meet the preset conditions reaches the preset time period, the target tuning parameter value is further determined, and Tuner of the transmitting antenna is tuned based on the target tuning parameter value, so that the interface of dynamic tuning is prevented from being frequently called, and the use experience of a user is prevented from being influenced.

Fig. 4 is a flow chart of another antenna tuning method illustrated by the present disclosure according to an exemplary embodiment.

In the description of this embodiment, the same steps as those in any of the foregoing embodiments will be described briefly, and reference will be made to any of the foregoing embodiments specifically. In the description of the present embodiment, how to determine the target tuning parameter according to the uplink block error rates of the plurality of SIM cards, and further tune the Tuner based on the target tuning parameter will be described. As shown in fig. 4, the exemplary embodiment method may include the steps of:

In step 400, signal quality of the network where the plurality of SIM cards are respectively located is measured, so as to obtain at least one signal value corresponding to each SIM card.

The signal quality of the network may be reflected by RSRP (REFERENCE SIGNAL RECEIVED power ) or by SNR (Signal To Noise Ratio, signal-to-noise ratio), which is not limited by the present disclosure.

In step 402, a target signal value corresponding to each SIM card is determined based on at least one signal value corresponding to each SIM card.

In step 404, a first difference of two target signal values satisfying a preset condition is determined.

For example, when the first preset threshold is 10db, the target signal value of the first SIM card is-95 db, and the target signal value of the second SIM card is-106 db, it may be determined that the target signal value of the second SIM card is 11db weaker than the target signal value of the first SIM card and greater than the first preset threshold by 10db. Namely, the target signal values of the first SIM card and the second SIM card meet the preset conditions. Thus, it may be determined that the first difference of the target signal values of the first and second SIM cards is 11db.

In step 406, a first tuning correction value is determined.

In an alternative example, before determining the first tuning correction value, uplink block error rates (blers, block Error Ratio) corresponding to the plurality of SIM cards respectively may be determined.

The uplink block error rate refers to the error probability of a transmission block on a transmitting antenna after CRC check. The higher the block error rate is, the worse the service operation quality of the corresponding SIM card is.

In the embodiment of the disclosure, the operating system of the terminal can monitor and acquire the block error rates of the first SIM card and the second SIM card in real time. For example, the block error rate of the second SIM card obtained by the operating system of the terminal at a certain moment is 12%, and the block error rate of the first SIM card is 6%.

The preset proportion may be set by the relevant staff based on the actual situation, for example, may be 10%. The first preset value may be, for example, 5db.

From the above, the uplink block error rate 12% corresponding to the second SIM card is greater than the preset proportion 10%, and the uplink block error rate 6% corresponding to the first SIM card is less than the preset proportion 10%, where at this time, the first preset value 5db may be determined as the first tuning correction value.

In step 408, a second difference between the first difference and the first tuning correction value is determined.

From the previous, the first difference is 11db, the first tuning correction value is 5db, and the second difference is 6db.

In step 410, a tuning parameter value corresponding to the second difference value is determined as the target tuning parameter value based on a correspondence between the different difference values and different tuning parameter values.

In the embodiment of the present disclosure, it may be determined that the tuning parameter value corresponding to the second difference value 6db is 3 based on the foregoing table 1, where the tuning parameter value 3 is the target tuning parameter value.

The correspondence may refer to the aforementioned first correspondence, second correspondence, or may refer to a third correspondence different from the aforementioned first correspondence and second correspondence, which is not limited by the present disclosure.

In step 412, the Tuner is tuned to increase the transmit power of at least one of the plurality of SIM cards based on the target tuning parameter value.

In the embodiment of the disclosure, after tuning the Tuner of the transmitting antenna based on the target tuning parameter value 3, the transmitting power of the second SIM card may be increased.

In an alternative example, after tuning Tuner of the transmit antenna, the method further comprises:

Continuing with the previous example, if the second SIM card has an obtained block error rate of 11% and the first SIM card has a block error rate of 7% after tuning Tuner of the transmitting antenna based on the target tuning parameter value 3. That is, the uplink block error rate corresponding to the second SIM card is still greater than the preset proportion, and when the uplink block error rate corresponding to the first SIM card is still less than the preset proportion, it indicates that the tuning amplitude at this time still can not promote the service quality of the second SIM card to a normal state. At this time, the tuning amplitude can be increased.

Specifically, a difference between the first tuning correction value and the second preset value may be determined as a new first tuning correction value.

For example, the second preset value may be 1, and at this time, the determined new first tuning correction value is 4db. After the step of determining the first difference and the second difference of the first tuning correction value is performed, the obtained second difference is 7db. Compared with the previous 6db, the tuning amplitude is increased, and the service quality of the second SIM card can be further improved.

The operating system of the terminal may perform the above steps in a loop until the service quality of the second SIM card after improvement reaches a certain standard, or the determined new first tuning correction value is 0, i.e. the tuning amplitude reaches the maximum tuning amplitude.

The antenna tuning method provided by the embodiment of the disclosure determines the first tuning correction value based on a block error rate, and further determines the target tuning parameter value according to a difference value between the first difference value and the first tuning correction value. The corresponding relation between the block error rate and the first tuning correction value is determined by a tuning experiment of related staff under a test network in advance, so that the service stability and fluency of two SIM cards can be balanced better.
