Example two
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for configuring an antenna of a terminal according to a second embodiment of the present invention, where the terminal includes at least two antennas, and the method includes:
and S11, acquiring the current signal quality parameter value of the terminal.
In an embodiment of the present invention, the terminal may be a mobile phone, a notebook computer, a wearable device, and the like, which is not particularly limited in this respect.
In the embodiments of the present invention, the antenna refers to a device capable of effectively radiating electromagnetic waves in a specific direction in space or capable of effectively receiving electromagnetic waves in a specific direction in space, and the antenna is a converter that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually, free space) or vice versa. Therefore, it is known that the antennas have both transmitting and receiving functions, and there is a possibility that some antenna is used only for reception (for example, a broadcast antenna) in the field.
In the embodiment of the present invention, the terminal may operate in multiple communication systems, and the terminal includes at least two antennas.
Specifically, the step S11 of acquiring the current signal quality parameter value of the terminal includes:
acquiring a current communication system from a storage unit of the terminal;
and acquiring a signal quality parameter value corresponding to the current communication system from a modulation and demodulation unit of the terminal.
In the embodiment of the present invention, different transmission and communication systems correspond to different parameters representing signal quality, see table 1, for example, when the communication system is GSM, the corresponding parameter representing signal quality is RSSI. The following description will be made by taking the terminal as a mobile phone, the mobile phone does not occupy channel resources in idle mode, as long as it wants to communicate with the network, first, a request for allocating channels is provided to the network, wherein the signal request is sent on a common control channel, after receiving a signal request message sent from the mobile phone on the common control channel, the base station notifies the network, the network determines which channel to allocate to the mobile phone according to the occupation condition of the channel, the allocation result of the channel is sent to the mobile phone by the base station, and after receiving the message, the mobile phone jumps to a dedicated channel according to the indication of the network. After the mobile phone jumps to the dedicated control channel, it sends a service request to the base station to tell the base station that i/i has occupied the channel allocated to you and tell the network what kind of service needs to be performed, such as GSM, which can support many kinds of services, such as sending and receiving short messages, making calls, etc., for different services, the network may allocate different channel resources. After authentication request, service request confirmation, encryption mode, signal distribution and the like are carried out between the network and the mobile phone, the mobile phone can carry out communication. That is to say, when the terminal and the base station are in communication connection, the base station feeds back a communication system and an operating frequency band that can be connected to the terminal, and after the connection, the terminal writes information related to communication, such as the communication system and the operating frequency band, into a storage unit of the terminal, and then calculates a signal quality parameter from a modulation unit of the terminal.
TABLE 1
And S12, when the signal quality parameter value is smaller than a preset threshold value, acquiring the antenna containing the current working frequency band as the antenna to be selected.
It should be noted that, whether they are transmitting antennas or receiving antennas, they always operate within a certain frequency range (frequency bandwidth), i.e. an operating frequency band, and the frequency bandwidth of an antenna has two different definitions — one is: under the condition that the standing-wave ratio SWR is less than or equal to 1.5, the working frequency bandwidth of the antenna is wide; one means that: the antenna gain drops by a frequency bandwidth in the range of 3 db. In a mobile communication system, which is generally defined as the former one, the frequency bandwidth of an antenna is specifically the operating frequency range of the antenna when the standing-wave ratio SWR of the antenna does not exceed 1.5. Generally, there is a difference in antenna performance at each frequency point within the operating bandwidth, but the performance degradation caused by this difference is acceptable.
In the embodiment of the present invention, the preset threshold may be set by the terminal manufacturer and written in the storage unit, and the preset thresholds corresponding to different communication systems and different working frequency bands may be different, which is not specifically limited in the present invention.
In the embodiment of the present invention, the antennas do not necessarily include all working frequency bands, for example, the terminal includes 3 antennas, the antenna 1 is suitable for a low frequency band, the antenna 2 is suitable for a medium frequency band and a high frequency band, and the antenna 3 is suitable for a low frequency band, a medium frequency band and a high frequency band, if the current antenna is 3, the working frequency band is the high frequency band, and when the signal quality parameter value is smaller than a preset threshold value, the antenna 2 and the antenna 3 including the current working frequency band are obtained, and the antenna 1 is not operated.
Preferably, the preset threshold is a preset difference;
if the signal quality parameter value is smaller than the preset threshold, acquiring an antenna containing a current working frequency band as an antenna to be selected further includes:
acquiring a last signal quality parameter value;
obtaining a difference value obtained by subtracting the last signal quality parameter value from the current signal quality parameter value;
and when the difference is smaller than the preset difference, acquiring the antenna containing the current working frequency band as the antenna to be selected.
In the embodiment of the present invention, the last signal quality parameter value is a value of a signal quality parameter obtained last time relative to the current signal quality parameter obtained last time, and it can be understood that the storage unit of the terminal may store the signal quality parameter value obtained each time.
Specifically, the current signal quality parameter value is 60, the last signal quality parameter value obtained last time is 70, a difference obtained by subtracting the last signal quality parameter value from the current signal quality parameter value is-10, and when the preset difference is-5, the difference is smaller than the preset difference, and then screening of the antenna containing the current working frequency band needs to be performed.
S13, for any antenna to be selected, acquiring a signal quality parameter value of the antenna in each tuning state;
step S13 is performed after step S12 is performed, the antenna itself will operate in a tuning state, and when the usage scenario of the terminal changes, the signal quality parameter of the antenna becomes poor, which means that the antenna performance of the antenna in the current tuning state is not good enough, so the goal is to find the antenna with the best performance and tuning state.
In the embodiment of the present invention, the antenna may be capable of switching among a plurality of tuning states, so that when switching to each tuning state, a corresponding signal quality parameter value may be obtained.
Preferably, for any one of the antennas to be selected, the obtaining the signal quality parameter value of the antenna in each tuning state includes:
and sequentially switching the tuning states of any antenna to be selected to obtain the signal quality parameter value of the antenna in each tuning state.
Furthermore, the terminal also comprises a tuning device connected with each antenna; wherein each of said tuning means comprises at least two tuning states;
then, sequentially switching the tuning states of any one of the antennas to be selected, and acquiring the signal quality parameter value of the antenna in each tuning state includes:
for any antenna to be selected, acquiring all tuning states of the tuning device connected with the antenna;
and sequentially switching each tuning state of each tuning device.
In the embodiment of the present invention, the tuning means is controlled by the processing unit of the terminal, so that the tuning state can be sequentially switched according to the determination result obtained in step S12.
For example, referring to table 2, when the signal quality parameter value in step S12 is smaller than the preset threshold, an antenna having a current operating frequency band is obtained as an antenna to be selected, where the antenna to be selected includes an antenna 1 and an antenna 2, the tuning device corresponding to the antenna 1 has three tuning states a1, B1, and c1, the antenna 2 has three tuning states a2, B2, and c2, the current antenna is the antenna 1, and the current tuning state is a1, the tuning states B1 and c1 of the antenna 1 are sequentially switched, the tuning state may be switched by a tuning device a connected to the antenna 1, the switching direction may be switched to c1 first and then to B1, the signal quality parameter values corresponding to B1 and c1 are obtained, the tuning state of the antenna 2 is switched, the tuning state may be switched by a tuning device B connected to the antenna 2, the switching direction may be sequentially switched according to the sequence of a2, b2, and c2, or sequentially switched according to the sequence of b2, a2, and c2, which is not specifically limited in this respect, and then the signal quality parameter values corresponding to the tuning states of the antenna 2 are respectively obtained, it should be noted that the signal quality parameter values in table 2 do not represent actual values, but are only used for example.
TABLE 2
And S14, comparing the acquired signal quality parameter values to obtain an optimal signal quality parameter value.
In the embodiment of the present invention, the storage unit of the terminal may store the signal quality parameter value of each tuning state to which the terminal is switched, store the corresponding tuning state, and compare all the obtained signal quality parameter values after the tuning state of each antenna to be selected is switched, so as to obtain the optimal signal quality parameter value.
Referring to table 2, all the signal quality parameter values of the antenna to be selected, i.e. the signal quality parameter value 50 of the antenna 1, the tuning state a1, and the signal quality parameter value 55 of the antenna 2, the tuning state a2, are obtained from the storage unit, and as can be seen from table 2, the value of the tuning state b2 of the antenna 2 is the best among all the signal quality parameter values, so that the optimal signal quality parameter value is 70.
And S15, selecting a main antenna according to the optimal signal quality parameter value and switching the tuning state of the main antenna.
In an embodiment of the present invention, each tuning state corresponds to a signal quality parameter value, and each tuning state corresponds to a corresponding antenna.
Referring to table 2, according to the optimal signal quality parameter value 70, it is known that the current optimal tuning state is b2, the processing unit of the terminal selects the antenna 2 corresponding to the optimal signal quality parameter value 70 as a main antenna, and switches the tuning state of the main antenna to b 2.
In this embodiment of the present invention, if the to-be-selected antenna includes an antenna 1 and an antenna 2, the optimal signal quality parameter value of the antenna 1 is 80, and the optimal signal quality parameter value of the antenna 2 is also 80, any one of them may be selected, the antenna 1 may be used as a main antenna, and the antenna 2 may be used as a main antenna, and when the antenna 1 is used as a main antenna, the tuning state corresponding to the optimal signal quality parameter value 80 of the antenna 1 is switched to, and when the antenna 2 is used as a main antenna, the tuning state corresponding to the optimal signal quality parameter value 80 of the antenna 2 is switched to, which is not specifically limited in this respect.
Compared with the prior art, the antenna configuration method of the terminal disclosed by the invention comprises the steps of firstly obtaining the current signal quality parameter value of the terminal; when the signal quality parameter value is smaller than a preset threshold value, acquiring an antenna containing a current working frequency band as an antenna to be selected; then, for any antenna to be selected, acquiring a signal quality parameter value of the antenna in each tuning state; comparing the obtained signal quality parameter values to obtain an optimal signal quality parameter value; and finally, selecting a main antenna and switching the tuning state of the main antenna according to the optimal signal quality parameter value. The technical problems that in the prior art, the requirement on hardware of terminal equipment is high, the design workload is large and the implementation effect is poor are solved, the tuning states of the antennas are sequentially switched, so that the problem that in the prior art, a large number of tests are required to obtain a configuration parameter library is reduced, compared parameters in antenna tuning are signal quality parameters, the comparison mode is scientific and feasible, an optimal main antenna can be dynamically selected according to the comparison result, the optimal tuning state selection is achieved, the performance of the current antenna of the terminal is optimal, and the signal receiving capability of the antenna in the terminal equipment is improved.
