Fig. 1 shows the method 100 of transmitting audio data in tdd systems according to an embodiment of the present invention, this method
100 can be executed by the device of transmitting audio data, which is, for example, user equipment.As shown in Figure 1, this method 100 includes:
S110 determines user equipment for sending the ascending time slot of voice data to base station；
S120 determines second speech data according to the first voice data that the user equipment acquires, the second speech data
It does not include voice data corresponding with the ascending time slot in first voice data；
S130 sends the second speech data to the base station.
Specifically, for TDD system, on the one hand, user equipment sends to base station in ascending time slot and penetrates
Frequency signal, by collected voice data from user device transmissions to base station, which is pulse modulation signal；Separately
On the one hand, user equipment can be acquired in voice data of each time slot to user, and base station is sent in ascending time slot.
Since biggish transmission power can be used when ascending time slot user equipment sends radiofrequency signal to base station, and then user can be set
The ongoing voice collecting of standby audio parts institute generates interference, i.e. uplink TDD noise.Thus, if user equipment will mix
The transmitting voice signal of interference then can make those who answer hear drone noise to those who answer due to uplink TDD noise, from
And seriously affect uplink speech quality.
For this purpose, in embodiments of the present invention, when user equipment can determine the uplink for sending voice data to base station
Gap；And user equipment can will remove voice data corresponding with the ascending time slot in the first voice data of acquisition, i.e., will
The voice data and corresponding uplink TDD noise acquired during ascending time slot all removes, and obtains second speech data, in turn
The second speech data is sent to base station in ascending time slot by user equipment.Since user equipment is sent to the voice number of base station
Audio parts collected voice data in ascending time slot, therefore, the second speech data that those who answer receives are not included in
Not uplink TDD noise, uplink speech quality can be greatly enhanced.
Therefore, in the tdd systems of the embodiment of the present invention transmitting audio data method, pass through determine user equipment
To base station send voice data ascending time slot, and by the voice data that user equipment is sent to base station be determined as do not include with it is upper
The corresponding voice data of row time slot can eliminate uplink TDD noise, so as to promote uplink speech quality, and can be significant
Ground enhances user experience.
In S110, user equipment determines the user equipment for sending the ascending time slot of voice data to base station.At this
In inventive embodiments, user equipment can be determined based on the transport protocol between user equipment and base station for sending to base station
The ascending time slot of data, and the descending time slot of the data for receiving base station transmission.
Specifically, for example, for gsm system, the length of each frame is 4.615ms, wherein when each frame includes 8
Gap, the length of each time slot are 576.92us.Under talking state, user equipment is carried out using 1 time slot in this 8 time slots
The transmitting of voice data just has the hair that the pulse that a time span is 576.92us is used for data that is, every 4.615ms
It penetrates.Thus, transmitting signal when gsm system is conversed in simple terms, it is believed that being one is modulated at the arteries and veins that frequency is 216.68Hz
The signal rushed to, when the pulse-modulated signal seals in audio parts (such as microphone, audio codec by some paths
Deng) in when, the pulse envelope (Envelope) of the pulse-modulated signal can bring about the uplink TDD noise of gsm system.
In the gsm system, user equipment uses 1 ascending time slot and 1 descending time slot to carry out the transmission of data respectively,
And provide that ascending time slot falls behind 3 time slots of descending time slot in agreement.Base station can be set after connecting with user equipment to user
Back-up is used in the ascending time slot and descending time slot of data transmission, and can pass through the modes notifying user equipments such as broadcast.Thus,
For user equipment, user equipment can the modes such as notice based on base station, know for sending voice data to base station
Ascending time slot.
It should be understood that the embodiment of the present invention is only said so that base station notifies the ascending time slot to user equipment broadcast as an example
It is bright, but the present invention is not limited thereto, and user equipment can also know ascending time slot relevant information using other methods.
In S120, user equipment can use various ways, so that the voice data that user equipment is sent to the base station
It does not include the voice data acquired during the ascending time slot and corresponding uplink TDD noise.
For example, in embodiments of the present invention, user equipment can be abandoned directly in the first voice data collected and is somebody's turn to do
The corresponding voice data of ascending time slot, i.e., be directly discarded in the voice data acquired during the ascending time slot, thus can also lose
Abandon the uplink TDD noise that may be sealed in the ascending time slot.It should be understood that although the program will lead to the appearance of voice breakpoint, but
Since the length of each time slot is only 576.92us, interval time is extremely short, will not cause any negative shadow to receiving for those who answer
It rings.
In another example in order to avoid the appearance of voice breakpoint, it in embodiments of the present invention, can also be to during the ascending time slot
The voice data of acquisition is replaced processing, equally can be avoided uplink TDD noise being sent to those who answer.
Specifically, Fig. 2 shows the methods 120 of determining second speech data according to an embodiment of the present invention, such as Fig. 2 institute
Show, second speech data determined according to the first voice data that the user equipment acquires, comprising:
S121 determines the time interval adjacent with the ascending time slot；
S122 determines voice data corresponding with the time interval in first voice data；
S123 replaces with voice data corresponding with the ascending time slot in first voice data and the time interval phase
The voice data answered, and replaced first voice data is determined as the second speech data.
In embodiments of the present invention, user equipment can be determined as this in previous time slot for adjacent with the ascending time slot
Time interval；It can also be determined as the time interval in the latter time slot for adjacent with the ascending time slot；Can also will with this
Ascending time slot is adjacent to be determined as the time interval in previous time slot and/or in a part of time slot of the latter time slot.As a result,
User equipment can replace with voice data corresponding with the ascending time slot in first voice data and the time interval phase
The voice data answered replaces the voice data that may introduce uplink TDD noise, using other voice data so as to complete
It totally disappeared except uplink TDD noise.
Thus, in embodiments of the present invention, optionally, the time interval be it is adjacent with the ascending time slot in preceding time slot or
It is adjacent with the ascending time slot in rear time slot；Or
The time interval include it is adjacent with the ascending time slot in preceding half-slot and it is adjacent with the ascending time slot
Half-slot afterwards.
It should be understood that the only voice data replacement to be acquired in the time interval adjacent with the ascending time slot of the embodiment of the present invention
It is illustrated for voice data corresponding with the ascending time slot, but the present invention is not limited thereto, other non-phases can also be used
The voice data of adjacent time slot replaces voice data corresponding with the ascending time slot, equally can be avoided uplink TDD noise
It is sent to those who answer, to can also eliminate uplink TDD noise, promotes uplink speech quality, and user can be enhanced significantly
Experience.
For example, in embodiments of the present invention, which includes adjacent with the ascending time slot at first 3/4ths
Time slot and adjacent with the ascending time slot in rear a quarter time slot；In another example in embodiments of the present invention, between the time
Every including adjacent with the ascending time slot in preceding a quarter time slot and adjacent with the ascending time slot rear 3/4ths
A time slot etc..
Therefore, in the tdd systems of the embodiment of the present invention transmitting audio data method, pass through determine user equipment
To base station send voice data ascending time slot, and by the voice data that user equipment is sent to base station be determined as do not include with it is upper
The corresponding voice data of row time slot can eliminate uplink TDD noise, so as to promote uplink speech quality, and can be significant
Ground enhances user experience.
In embodiments of the present invention, when the power of the radiofrequency signal of user equipment transmitting is bigger, interference signal is easier
Audio parts are sealed in, thus when user equipment uses maximum power transmission, uplink TDD noise is also the largest.But Ying Li
Solution, this is not meant to can just there be the uplink TDD noise when only user equipment maximum power transmission.Specifically, if with
When the transmission power of family equipment is sufficiently large, which will seal in audio parts, thus will have uplink TDD and make an uproar
Sound.
Thus, in embodiments of the present invention, optionally, as shown in figure 3, this method 100 further include:
S140 determines that the user equipment sends the uplink transmission power that upstream data uses；
S150 determines the size relation between the uplink transmission power and power threshold；
Wherein, this determines second speech data according to the first voice data that the user equipment acquires, comprising:
S124, it is true according to first voice data when determining that the uplink transmission power is greater than or equal to the power threshold
The fixed second speech data.
Specifically, in embodiments of the present invention, it can first determine that user equipment sends the uplink transmitting that upstream data uses
Size relation between power and power threshold, when the uplink transmission power is greater than or equal to the power threshold, it is believed that
The radiofrequency signal that user equipment is sent can generate interference to the voice data of acquisition, it is possible thereby to true according to first voice data
The fixed second speech data, i.e., will be removed in the first voice data of acquisition the voice data acquired during ascending time slot and
Corresponding uplink TDD noise.
And when the uplink transmission power be less than the power threshold when, it is believed that user equipment send radiofrequency signal due to
Power is lower, interference will not be generated to the voice data of acquisition, it is possible thereby to the first voice number for directly acquiring user equipment
According to base station is sent to, without handling first voice data.
In embodiments of the present invention, optionally, which is the maximum uplink transmission power of the user equipment.Exist
When user equipment is using maximum uplink transmission power transmitting data, the first voice data of acquisition is handled, by this first
