For convenience, the embodiment of the present invention will illustrate for the gsm system based on TDMA technology, but the present invention is not limited to this.
Fig. 1 illustrates the method 100 of transmitting audio data in tdd systems according to embodiments of the present invention, and the method 100 can be performed by the device of transmitting audio data, and this device is such as subscriber equipment.As it is shown in figure 1, the method 100 includes:
S110, it is determined that subscriber equipment for sending the ascending time slot of speech data to base station；
S120, determines second speech data according to the first speech data that this subscriber equipment gathers, and this second speech data does not include speech data corresponding with this ascending time slot in this first speech data；
S130, sends this second speech data to this base station.
Specifically, for TDD system, on the one hand, subscriber equipment sends radiofrequency signal at ascending time slot to base station, with the speech data that will collect from user device transmissions to base station, this radiofrequency signal is pulse modulation signal；On the other hand, the speech data of user can be acquired by subscriber equipment at each time slot, and is sent to base station in ascending time slot.Owing to can adopt bigger transmitting power when ascending time slot subscriber equipment sends radiofrequency signal to base station, and then the ongoing voice collecting of subscriber equipment audio parts institute can be produced interference, i.e. up TDD noise.Thus, if the transmitting voice signal that mixing is disturbed by subscriber equipment to those who answer, then can make those who answer hear drone noise due to this up TDD noise, thus having a strong impact on up speech quality.
For this, in embodiments of the present invention, subscriber equipment may determine that the ascending time slot for sending speech data to base station；And subscriber equipment can will remove speech data corresponding with this ascending time slot in the first speech data gathered, the speech data and the corresponding up TDD noise that are about to collection during ascending time slot are all removed, obtain second speech data, and then this second speech data is sent to base station by subscriber equipment in ascending time slot.Not comprising, owing to subscriber equipment is sent in the speech data of base station, the speech data that audio parts collects when ascending time slot, therefore, the second speech data that those who answer receives is this up TDD noise not, and up speech quality can be greatly enhanced.
Therefore, the method of transmitting audio data in the tdd systems of the embodiment of the present invention, it is determined by subscriber equipment and sends the ascending time slot of speech data to base station, and the speech data that subscriber equipment is sent to base station is defined as not including speech data corresponding with ascending time slot, up TDD noise can be eliminated, it is thus possible to promote up speech quality, and Consumer's Experience can be strengthened significantly.
In S110, subscriber equipment determines that this subscriber equipment for sending the ascending time slot of speech data to base station.In embodiments of the present invention, subscriber equipment can based on the host-host protocol between subscriber equipment and base station, it is determined that for sending the ascending time slot of data to base station, and for receiving the descending time slot of the data that base station sends.
Specifically, for instance, for gsm system, the length of each frame is 4.615ms, and wherein each frame includes 8 time slots, and the length of each time slot is 576.92us.Under talking state, subscriber equipment adopts 1 time slot in these 8 time slots to carry out the transmitting of speech data, namely every 4.615ms, just has the pulse transmitting for data that time span is 576.92us.Thus, transmitting signal during gsm system call in simple terms, it is regarded as a signal being modulated in the pulse that frequency is 216.68Hz, when this pulse-modulated signal is sealed in audio parts (such as mike, audio codec etc.) by some paths, the pulse envelope (Envelope) of this pulse-modulated signal can bring about the up TDD noise of gsm system.
In this gsm system, subscriber equipment uses 1 ascending time slot and 1 descending time slot to carry out the transmission of data respectively, and specifies in agreement that ascending time slot falls behind 3 time slots of descending time slot.Base station is after being connected with subscriber equipment, it is possible to be used for ascending time slot and the descending time slot of data transmission to user equipment allocation, it is possible to by mode notifying user equipment such as broadcast.Thus, for subscriber equipment, subscriber equipment based on modes such as the notices of base station, can know the ascending time slot for sending speech data to base station.
It should be understood that the embodiment of the present invention only illustrates for base station to this ascending time slot of subscriber equipment broadcast announcement, but the present invention is not limited to this, and subscriber equipment can also adopt additive method to know ascending time slot relevant information.
In S120, subscriber equipment can adopt various ways so that the speech data that subscriber equipment sends to this base station is not included in the speech data gathered during this ascending time slot and corresponding up TDD noise.
Such as, in embodiments of the present invention, subscriber equipment can directly abandon speech data corresponding with this ascending time slot in the first speech data gathered, and is namely directly discarded in the speech data gathered during this ascending time slot, thus can also be discarded in the up TDD noise that this ascending time slot is likely to seal in.Although should be understood that the program can cause the appearance of voice breakpoint, but owing to the length of each time slot is only 576.92us, interval time being extremely short, receiving of those who answer will not be caused any negative effect.
Again such as, in order to avoid the appearance of voice breakpoint, in embodiments of the present invention, it is also possible to the speech data gathered during this ascending time slot is replaced process, same it can be avoided that this up TDD noise is sent to those who answer.
Specifically, Fig. 2 illustrates the method 120 of determination second speech data according to embodiments of the present invention, as in figure 2 it is shown, the first speech data gathered according to this subscriber equipment determines second speech data, including:
S121, it is determined that the interval adjacent with this ascending time slot；

Therefore, the method of transmitting audio data in the tdd systems of the embodiment of the present invention, it is determined by subscriber equipment and sends the ascending time slot of speech data to base station, and the speech data that subscriber equipment is sent to base station is defined as not including speech data corresponding with ascending time slot, up TDD noise can be eliminated, it is thus possible to promote up speech quality, and Consumer's Experience can be strengthened significantly.
In embodiments of the present invention, when the power of the radiofrequency signal of subscriber equipment transmitting is more big, interference signal more easily seals in audio parts, thus when subscriber equipment adopts maximum power transmission, this up TDD noise is also maximum.It should be understood that this is not meant to only have during subscriber equipment maximum power transmission just can there is this up TDD noise.Specifically, as long as the transmitting power of subscriber equipment is sufficiently large, this radiofrequency signal will seal in audio parts, thus will there is this up TDD noise.
Thus, in embodiments of the present invention, alternatively, as it is shown on figure 3, the method 100 also includes:
S140, it is determined that this subscriber equipment sends the uplink transmission power that upstream data adopts；
S150, it is determined that the magnitude relationship between this uplink transmission power and power threshold；
Wherein, this first speech data gathered according to this subscriber equipment determines second speech data, including:
S124, when determining this uplink transmission power more than or equal to this power threshold, determines this second speech data according to this first speech data.
Specifically, in embodiments of the present invention, can first determine that subscriber equipment sends the magnitude relationship between uplink transmission power and the power threshold that upstream data adopts, when this uplink transmission power is more than or equal to this power threshold, it is believed that the speech data gathered can be produced interference by the radiofrequency signal that subscriber equipment sends, thus can determine this second speech data according to this first speech data, be about in the first speech data gathered and remove the speech data gathered during ascending time slot and corresponding up TDD noise.
And when this uplink transmission power is less than this power threshold, it is believed that the radiofrequency signal of subscriber equipment transmission is relatively low due to power, the speech data gathered will not be produced interference, thus directly the first speech data of subscriber equipment collection can be sent to base station, this first speech data need not be processed.
In embodiments of the present invention, alternatively, this power threshold is the maximum uplink transmission power of this subscriber equipment.Namely, when subscriber equipment adopts maximum uplink transmission power to launch data, the first speech data gathered being processed, speech data corresponding with this ascending time slot in this first speech data being removed, thus eliminating up TDD noise.
It should be understood that the maximum uplink transmission power that the embodiment of the present invention is only this subscriber equipment for this power threshold illustrates, the present invention is not limited to this, and this power threshold can also be other performance number.
Will also be understood that, in various embodiments of the present invention, the size of the sequence number of above-mentioned each process is not meant to the priority of execution sequence, and the execution sequence of each process should be determined with its function and internal logic, and the implementation process of the embodiment of the present invention should not constituted any restriction.
