Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

Example one

Referring to fig. 3, which illustrates a method for antenna switching according to an embodiment of the present invention, the method is applied to a mobile terminal, and the method may include:

s301: in the establishing process of the call link, judging whether a first antenna coupled to a transmitting circuit meets a preset antenna switching condition; wherein the first antenna is an initially selected transmit antenna;

s302: coupling the transmitting circuit to a second antenna by controlling the first antenna to switch to the second antenna when the first antenna satisfies a preset antenna switching condition; the second antenna is any one antenna except the first antenna;

s303: and continuing to establish the call link according to the second antenna.

In the embodiment of the invention, the establishment process of the call link mainly refers to the establishment process of the call link between the mobile terminal of the calling party and the external network or the establishment process of the call link between the mobile terminal of the called party and the external network. Generally, a mobile terminal includes two antennas, namely a first antenna and a second antenna, wherein the first antenna is an initially selected transmitting antenna, and the second antenna is any other antenna except the first antenna; the mobile terminal can simultaneously receive signals transmitted from an external network through the two antennas; however, when the mobile terminal transmits a signal to an external network, the signal can be transmitted through only one antenna at the same time. According to the technical scheme shown in fig. 3, in the establishing process of the call link, the antenna switching is controlled by increasing the judgment on whether the first antenna coupled to the transmitting circuit meets the preset antenna switching condition, so that the technical problem that the call link cannot be successfully established to cause call failure when the initially selected first antenna is poor in state or the received signal strength is too weak is avoided, the success rate of establishing the call link by the mobile terminal is improved, the call requirement of a user is ensured, and the user experience is improved.

For step S301, the preset antenna switching condition is used to perform antenna switching from the first antenna to the second antenna when the first antenna coupled to the transmitting circuit satisfies the antenna switching condition; the antenna switching conditions of each antenna are consistent, and the specific antenna switching conditions can be set according to needs.

In the embodiment of the invention, the mobile terminal also comprises a transmitting circuit and a receiving circuit. A measurement circuit is arranged in the receiving circuit and is used for measuring the performance measurement value of the antenna; in particular, by configuring the receive circuitry to receive a mode of signals via the first antenna and the second antenna, the mobile terminal may utilize measurement circuitry in the receive circuitry to obtain performance measurements of the first antenna and performance measurements of the second antenna. The performance measurement value of the antenna is generally used for measuring the performance index of the antenna receiving signal, and can be used as a standard for evaluating the performance of the antenna. In the establishing process of the call link, selecting the antenna with the optimal signal receiving performance to be coupled to the transmitting circuit for signal transmission, so that the success rate of establishing the call link by the mobile terminal can be improved; therefore, for step S301, in a possible implementation manner, referring to fig. 4, the determining whether the first antenna coupled to the transmitting circuit satisfies the preset antenna switching condition specifically includes:

s401: acquiring a performance measurement value of a first antenna and a performance measurement value of a second antenna;

s402: comparing the performance measurement of the first antenna to the performance measurement of the second antenna;

s403: when the performance measurement value of the second antenna is higher than that of the first antenna, confirming that the first antenna meets a preset antenna switching condition;

s404: and when the performance measurement value of the second antenna is not higher than the performance measurement value of the first antenna, confirming that the first antenna does not meet a preset antenna switching condition.

It is understood that the performance measurements of the antenna may include: the signal power, signal strength, sensitivity, noise ratio, and other measurement values that reflect the performance index of the antenna received signal may be specifically set as needed. For example, assuming that the performance measurement value set by the mobile terminal is signal strength, by coupling the first antenna and the second antenna to the receiving circuit, the signal strength values of the first antenna and the second antenna are measured by using the measuring circuit in the receiving circuit, for example, the signal strength value of the first antenna obtained by the mobile terminal is-90 dB, and the signal strength value of the second antenna is-60 dB; the smaller the absolute value of the signal strength is, the stronger the signal strength is, which indicates that the performance of the antenna for receiving signals is better; therefore, when the signal strength value of the second antenna is higher than that of the first antenna, it indicates that the performance of the second antenna is better than that of the first antenna, and at this time, it is a better choice to select the second antenna as the transmitting antenna; therefore, when the signal strength value of the second antenna is higher than the signal strength value of the first antenna, it can be determined that the first antenna satisfies the predetermined antenna switching condition, and then the antenna switching from the first antenna to the second antenna is performed. Assuming that the signal intensity value of the first antenna obtained by the mobile terminal is-50 dB, and the signal intensity value of the second antenna is-60 dB; the signal strength value of the second antenna is lower than that of the first antenna, which shows that the performance of the second antenna is poorer than that of the first antenna, and at the moment, the first antenna is kept to be selected as the transmitting antenna to be a better choice; accordingly, when the signal strength value of the second antenna is lower than the signal strength value of the first antenna, it may be confirmed that the first antenna does not satisfy the preset antenna switching condition, so that the antenna switching from the first antenna to the second antenna is not performed.

In the implementation of fig. 4, since it is necessary to obtain the performance measurement value of the first antenna and the performance measurement value of the second antenna by using the measurement circuit, and then confirm whether the first antenna coupled to the transmission circuit satisfies the preset antenna switching condition by comparing the performance measurement value of the first antenna and the performance measurement value of the second antenna; in some cases, the antenna is temporarily blocked or interfered to bias the performance measurement, resulting in the selection of an antenna that is not the best for received signal performance; and the measurement of performance measurements may add complexity and/or time required for the set-up process for the telephony link; therefore, as for step S301, in another possible implementation manner, referring to fig. 5, the determining whether the first antenna coupled to the transmitting circuit meets the preset antenna switching condition specifically includes:

step S501: counting the failure times of establishing a call link according to the first antenna;

step S502: comparing the failure times with a first preset threshold value;

step S503: when the failure times are equal to a first preset threshold value, confirming that the first antenna meets a preset antenna switching condition;

step S504: and when the failure times are smaller than a first preset threshold value, confirming that the first antenna does not meet a preset antenna switching condition.

It should be understood that the first predetermined threshold, which is a predetermined number of times of failure allowed for establishing a call link according to the first antenna coupled to the transmitting circuit, may be set to 5 times. For example, the mobile terminal first establishes a call link according to an initially selected first antenna coupled to the transmitting circuit, and in case of a first call link establishment failure, the mobile terminal allows multiple attempts to establish a call link with an external network (e.g., a base station); here, the method for allowing the mobile terminal to make multiple attempts may be to transmit the call link establishment request signal in a manner of being powered at each time, or may be to transmit the call link establishment request signal in a manner of being powered up one by one. When the number of times of failure of establishing the call link satisfies 5 times, it indicates that the call link is failed to be established by selecting the first antenna as the transmitting antenna, and the first antenna can be confirmed to satisfy a preset antenna switching condition, so as to execute antenna switching from the first antenna to the second antenna; when the number of times of failure of establishing the call link is less than 5 times, it indicates that the call link is successfully established by selecting the first antenna as the transmitting antenna, and it may be determined that the first antenna does not satisfy a preset antenna switching condition, so that antenna switching from the first antenna to the second antenna is not performed.

Compared with the implementation shown in fig. 4, in the implementation shown in fig. 5, the implementation shown in fig. 5 does not need to use the measurement circuit to obtain the performance measurement value of the first antenna and the performance measurement value of the second antenna, but determines whether the first antenna coupled to the transmitting circuit meets the preset antenna switching condition during the establishment of the call link by counting the number of failures of establishing the call link according to the first antenna and comparing the number with the first preset threshold; the phenomenon that the performance measurement value is deviated due to the fact that the antenna is temporarily shielded or interfered, and therefore the selected antenna is not optimal in received signal performance is avoided.

For step S302, that is, when the performance measurement value of the second antenna of the mobile terminal is higher than the performance measurement value of the first antenna, or the number of times of failure of the mobile terminal to establish the call link according to the first antenna is equal to a first preset threshold, it is determined that the first antenna meets a preset antenna switching condition, and at this time, the mobile terminal couples the transmitting circuit to the second antenna by controlling the first antenna to switch to the second antenna; therefore, after step S302, for a case where the first antenna does not satisfy a preset antenna switching condition, the method further includes:

That is to say, when the performance measurement value of the second antenna of the mobile terminal is not higher than the performance measurement value of the first antenna, or the number of times of failure of the mobile terminal to establish the call link according to the first antenna is less than a first preset threshold, the mobile terminal keeps the initially selected first antenna as the transmitting antenna at this time, and still performs establishment of the call link according to the first antenna.

It should be noted that, after step S303, when the establishment of the call link is performed according to the second antenna, the establishment of the call link is not all successful; the success or failure of the call link establishment is also closely related to the magnitude of the performance measurement value of the second antenna and the number of times of failure of establishing the call link according to the second antenna.

After step S303, when the success or failure of establishing the call link is closely related to the magnitude of the performance measurement value of the second antenna, in a possible implementation manner, the method further includes:

It should be understood that the preset performance threshold refers to a threshold that is preset by the mobile terminal and represents the performance of the antenna for receiving signals when the call link between the mobile terminal and the external network is successfully established. For example, assuming that the performance measurement value set by the mobile terminal is signal strength, when the preset signal strength threshold value of the mobile terminal is-85 dB and the signal strength value of the second antenna is-90 dB, it can be seen that the signal strength value of the second antenna is lower than the preset signal strength threshold value, since the signal strength of the second antenna is too weak, it is not enough to support the mobile terminal to establish a call link with the external network, and the establishment of the call link is failed; when the preset signal strength threshold value of the mobile terminal is-85 dB and the signal strength value of the second antenna is-60 dB, it can be seen that the signal strength value of the second antenna is higher than the preset signal strength threshold value, and at this time, the signal strength of the second antenna is enough to support the mobile terminal to establish a call link with an external network, and the establishment of the call link is successful.

After step S303, when whether the call link is successfully established or not is closely related to the number of times of failure to establish the call link according to the second antenna, in another possible implementation manner, the method further includes:

comparing the failure times with a second preset threshold value;

It should be understood that the second preset threshold refers to a preset number of allowable failures for establishing a call link according to a second antenna coupled to the transmitting circuit; it should be noted that, the values of the second preset threshold and the first preset threshold may be the same or different. For example, assuming that the second preset threshold of the mobile terminal is 5 times, the mobile terminal establishes the call link according to the second antenna coupled to the transmitting circuit, and when the number of failures of trying to establish the call link with the external network according to the second antenna satisfies 5 times, the process of establishing the call link with the external network according to the second antenna is terminated, and the establishment of the call link is failed; when the number of failures of trying to establish the call link with the external network according to the second antenna is less than 5 times, the call link with the external network according to the second antenna is successfully established, which indicates that the call link establishment is successful.

In addition, when the call link is established according to the second antenna coupled to the transmitting circuit, and the call link is failed to be established, the mobile terminal can also switch the second antenna to the third antenna, so that the transmitting circuit is coupled to the third antenna to continuously try to establish the call link; the third antenna is any other antenna except the first antenna and the second antenna, the first antenna is the initially selected transmitting antenna, and the selection sequence of the other antennas such as the second antenna and the third antenna is the antenna sequence selected based on the predefined antenna selection sequence or the random antenna sequence. Thus, after the above steps, the method further comprises:

and continuing to establish the call link according to the third antenna.

For example, assuming that the mobile terminal establishes the call link according to the second antenna, when the number of failed establishment times of the call link satisfies 5 times, it indicates that the call link establishment by the mobile terminal according to the second antenna is failed; at this time, the second antenna may be switched to the third antenna, and then the call link with the external network is attempted to be established according to the third antenna, that is, the mobile terminal may continue to establish the call link according to the third antenna. The mobile terminal performs the establishment procedure of the call link according to the third antenna, and the aforementioned mobile terminal performs the establishment procedure of the call link according to the second antenna may be referred to, and details are not described here.

The embodiment provides an antenna switching method, which is applied to a mobile terminal and used for judging whether a first antenna coupled to a transmitting circuit meets a preset antenna switching condition or not in the establishing process of a call link; coupling the transmitting circuit to a second antenna by controlling the first antenna to switch to the second antenna when the first antenna satisfies a preset antenna switching condition; continuing to establish the call link according to the second antenna; the technical problem that when the initially selected first antenna is poor in state or the received signal strength is too weak, the call link cannot be successfully established, and therefore call failure is caused is solved, the success rate of establishing the call link by the mobile terminal is improved, the call requirement of a user is guaranteed, and user experience is improved.

Example two

Based on the same inventive concept of the foregoing embodiment, referring to fig. 6, which shows a detailed flow of an antenna switching method provided in the embodiment of the present invention, taking the networking diagram established by the calling party call link of fig. 7 as an example, in fig. 7, the networking diagram established by the calling party call link mainly includes: a mobile terminal 701 of a calling party, a base station 702, a switch 703, and a transmitting circuit 704, a receiving circuit 705, a measuring circuit 706, a first antenna 707, and a second antenna 708 built in the mobile terminal 701 of the calling party; wherein the measurement circuit 706 is built in the receiving circuit 705, and the measurement circuit 706 is used for measuring performance measurement values of the first antenna 707 and the second antenna 708 which are coupled to the receiving circuit 705; the calling party call link establishment process is as follows: after the mobile terminal 701 of the calling party is pressed down the dial key, a call link establishment request signal is transmitted to the base station 702 through the first antenna 707 coupled to the transmitting circuit 704, and then the base station 702 transmits the request signal to the switch 703; the switch 703 returns a corresponding response signal to the base station 702, and then the response signal returned from the base station 702 may be simultaneously received by the first antenna 707 and the second antenna 708 coupled to the receiving circuit 705. Based on the calling party call link establishment procedure shown in fig. 7, the detailed procedure may include:

s601: in the establishing process of a call link, acquiring a performance measurement value of a first antenna and a performance measurement value of a second antenna; wherein the first antenna is an initially selected antenna coupled to a transmit circuit and the second antenna is any other antenna than the first antenna;

s602: comparing the performance measurement of the first antenna to the performance measurement of the second antenna;

it should be noted that, for step S602, after comparing the performance measurement value of the first antenna with the performance measurement value of the second antenna, when the performance measurement value of the second antenna is higher than the performance measurement value of the first antenna, step S603 is executed; when the performance measurement value of the second antenna is not higher than the performance measurement value of the first antenna, step S604 is performed.

S603: coupling the transmit circuit to the second antenna by controlling the first antenna to switch to the second antenna when the performance measurement of the second antenna is higher than the performance measurement of the first antenna;

s604: when the performance measurement value of the second antenna is not higher than the performance measurement value of the first antenna, continuing to establish the call link according to the first antenna;

for example, taking the calling party call link establishment procedure shown in fig. 7 as an example, the signal strength values of the first antenna 707 and the second antenna 708 are measured by the measurement circuit 706 built in the receiving circuit 705, assuming that the signal strength value of the first antenna 707 is-90 dB and the signal strength value of the second antenna 708 is-60 dB, since the signal strength value of the second antenna 708 is higher than the signal strength value of the first antenna 707, the first antenna 707 coupled to the transmitting circuit 704 is switched to the second antenna 708, and then a call link is established according to the second antenna 708; assuming that the signal strength value of the first antenna 707 is-55 dB and the signal strength value of the second antenna 708 is-60 dB, since the signal strength value of the second antenna 708 is lower than the signal strength value of the first antenna 707, no antenna switching is performed and the call link is still established according to the first antenna 707.

After step S603, step S605 needs to be executed; comparing the performance measurement value of the second antenna with a preset performance threshold value; when the performance measurement value of the second antenna is lower than the preset performance threshold value, executing step S606; and when the performance measurement value of the second antenna is not lower than the preset performance threshold value, executing step S607.

S605: comparing the performance measurement value of the second antenna with a preset performance threshold value;

s606: when the performance measurement value of the second antenna is lower than the preset performance threshold value, the call link is failed to be established;

s607: and when the performance measurement value of the second antenna is not lower than the preset performance threshold value, the call link is established successfully.

For example, still taking the call link establishment procedure of the calling party shown in fig. 7 as an example, with reference to the above example, assuming that the preset signal strength threshold is-85 dB and the signal strength value of the second antenna 708 is-90 dB, the signal strength value of the second antenna 708 is lower than the preset signal strength threshold, and at this time, the call link establishment is failed; assuming that the preset signal strength threshold is-85 dB and the signal strength value of the second antenna 708 is-60 dB, the signal strength value of the second antenna 708 is higher than the preset signal strength threshold, and at this time, the establishment of the call link is successful.

Through the embodiment, the specific implementation of the embodiment is elaborated in detail, and it can be seen that through the technical scheme of the embodiment, the success rate of establishing the call link is improved, the call requirement of the user is ensured, and the user experience is improved.

s801: counting the number of failures in establishing a call link according to a first antenna coupled to a transmit circuit;

s802: comparing the failure times with a first preset threshold value;

it should be noted that, for step S802, the failure times are compared with a first preset threshold, and when the failure times are equal to the first preset threshold, step S803 is executed; and executing step S804 when the failure times are smaller than a first preset threshold.

S803: coupling the transmit circuit to a second antenna by controlling the first antenna to switch to the second antenna when the number of failures equals a first preset threshold;

s804: when the failure times are smaller than a first preset threshold value, continuing to establish the call link according to the first antenna;

for example, still taking the call link establishment procedure of the calling party shown in fig. 7 as an example, assuming that the first preset threshold of the mobile terminal 701 of the calling party is 5 times, the first antenna 707 coupled to the transmitting circuit 704 is first utilized to transmit a call link establishment request signal to establish a call link, when the number of failures of trying to establish a call link with the base station 702 according to the first antenna 707 satisfies 5 times, the call link establishment according to the first antenna 707 is failed, antenna switching needs to be performed, and then the call link is established according to the second antenna 708; when the number of failures to attempt to establish the communication link with the base station 702 via the first antenna 707 is less than 5 times, the antenna switching is not performed, and the establishment of the communication link is still continued via the first antenna 707.

It should be noted that, after step S803, step S805 needs to be executed to count the number of times of failure of establishing a call link according to the second antenna; then, step S806 is executed to compare the failure times with a second preset threshold; when the failure times are equal to a second preset threshold, executing step S807; and when the failure times are smaller than a second preset threshold, executing step S808.

S805: counting the failure times of establishing a call link according to the second antenna;

s806: comparing the failure times with a second preset threshold value;

s807: when the failure times are equal to a second preset threshold value, the call link is failed to be established;

s808: and when the failure times are smaller than a second preset threshold value, the call link is established successfully.

For example, still taking the calling party talking link establishing process shown in fig. 7 as an example, in combination with the above example, assuming that the second preset threshold of the calling party's mobile terminal 701 is also 5 times, when the transmitting circuit 704 is coupled to the second antenna 708, the calling party's mobile terminal 701 transmits a talking link establishing request signal according to the second antenna 708 to establish a talking link; when the number of failures of attempting to establish the call link with the base station 702 according to the second antenna 708 satisfies 5 times, ending the process of establishing the call link with the base station 702 according to the second antenna 708, the establishment of the call link being failed; when the number of failures to attempt to establish the call link with the base station 702 via the second antenna 708 is less than 5, it indicates that the call link with the base station 702 via the second antenna 708 has been successfully established, and the call link is successfully established.
