[0137] DTMF technology is a signal transmission method used to indicate key input. Through DTMF technology, two tone signals with different frequencies can be used to represent a key input. The key input can be a number, letter, or symbol.

[0138] In some embodiments, DTMF technology can map a key input to a unique tone combination (i.e., a combination of a high-frequency tone and a low-frequency tone). When a user triggers a key on a terminal, the terminal can transmit two tone signals included in the tone combination mapped to the triggered key, thereby representing the triggered key through the transmitted tone combination. The receiving terminal can then identify the triggered key by recognizing the received tone signals and restore the key input content issued by the terminal.

[0139] Referring to FIG2 , FIG2 is a schematic diagram of a DTMF keyboard according to an embodiment of the present disclosure. As shown in FIG2 , the DTMF keyboard may include 16 keys, namely “0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, *, #”. Each key may be mapped to a tone combination, and the tone combinations mapped to different keys are different. For example, key 1 may be mapped to a tone combination consisting of a low-frequency tone with a frequency of 697 Hz and a high-frequency tone with a frequency of 1209 Hz, key 2 may be mapped to a tone combination consisting of a low-frequency tone with a frequency of 697 Hz and a high-frequency tone with a frequency of 1336 Hz, and so on.

[0140] In some embodiments, each DTMF transmission process needs to be implemented using a set of DTMF signaling, which may include the following four signalings:

[0141] START DTMF: Request signaling to initiate DTMF signaling, used to indicate the start of sending DTMF signals;

[0142] START DTMF ACK: DTMF signaling confirmation signal, indicating that the START DTMF signaling has been received and is ready to start sending DTMF signals;

[0143] STOP DTMF: Request signaling to stop DTMF signaling, used to instruct to stop sending DTMF signals;

[0144] STOP DTMF ACK: DTMF signaling confirmation signal, indicating that the STOP DTMF signaling has been received and the sending of DTMF signals has stopped.

[0145] DTMF technology is often used in everyday situations, such as making phone calls (e.g., entering extension numbers), entering account numbers, ID numbers, passwords, and recharge numbers. DTMF technology is also commonly used in satellite communications. However, because satellites (especially the Tiantong satellites in geostationary orbit) are far above the Earth, transmission takes a long time. Entering multiple keys also increases the transmission time. Consequently, when entering multiple keys over a satellite network, the cumulative delay can lead to significant transmission delays. If the waiting time set on the receiving end is shorter than the time required to transmit these multiple keystrokes, transmission failure may occur. For example, if entering a keystroke takes approximately 3 seconds, dialing a 5-digit extension number will take approximately 15 seconds. If the waiting time set on the receiving end is less than 15 seconds, the extension call will fail.

[0146] Therefore, how to realize DTMF transmission in satellite communications has become a technical problem that needs to be solved urgently in satellite communications.

[0147] The above embodiments are mainly illustrated by taking DTMF transmission in satellite communication as an example. In more possible implementation methods, DTMF transmission can be used in any communication scenarios such as 4G, 5G, 6G, Internet of Vehicles and their improved versions. In addition, DTMF transmission may have the problem of large transmission delay due to the continuous accumulation of delays of multiple key presses. The embodiments of the present disclosure do not limit the specific application scenarios.

[0148] FIG3 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG3 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0149] Step S3101: The terminal obtains the coded data corresponding to the first DTMF key that is triggered.

[0150] In some embodiments, the terminal may detect the triggering of the DTMF button, and when detecting that the DTMF button is triggered, obtain the coded data corresponding to the first triggered DTMF button.

[0151] In some embodiments, when it is detected that a DTMF button is triggered, encoding may be performed based on the button information of the first triggered DTMF button to obtain encoded data corresponding to the first triggered DTMF button.

[0152] In some embodiments, upon detecting a DTMF signal generated by triggering a DTMF button, it may be determined that the DTMF button is triggered, and the button information of the triggered DTMF button may be acquired based on the DTMF signal.

[0153] Among them, the DTMF signal may include two tone signals (such as a high-frequency tone signal and a low-frequency tone signal), and these two tone signals can be used as a tone combination. The mapping relationship between different tone combinations and triggered keys can be pre-set, so that the triggered DTMF key can be determined based on the triggered key mapped to the tone combination corresponding to the received DTMF signal.

[0154] Optionally, after the DTMF key is determined, key information of the determined DTMF key may be acquired, so that encoding may be performed based on the acquired key information to achieve acquisition of encoded data.

[0155] The key information may be the content represented by the DTMF key, for example, the key information may be numbers, letters, symbols, etc. represented by the DTMF key, but is not limited thereto.

[0156] Optionally, when encoding is performed based on the acquired key information, it can be implemented based on any encoding standard, or in other words, when encoding is performed based on the acquired key information, it can be implemented using any encoding algorithm.

[0157] For example, the key information may be encoded based on the American Standard Code for Information Interchange (ASCII), but is not limited thereto.

[0158] Step S3102: The terminal sends a first signaling to the network device.

[0159] The first signaling may include a coded data corresponding to the first DTMF key that is triggered.

[0160] Optionally, the encoded data may be located in a protocol data unit (PDU) of the first signaling, but is not limited thereto, and the encoded data may also be located at other locations in the first signaling.

[0161] In some embodiments, the first signaling may include indication information, which can be used to indicate the number of DTMF keys corresponding to the encoded data carried by the first signaling, so that the network device can know how many DTMF keys correspond to the encoded data carried by the first signaling based on the indication information carried by the first signaling.

[0162] Optionally, the indication information may be located in a data packet header of the first signaling, but is not limited thereto, and the indication information may also be located at other locations in the first signaling.

[0163] The first signaling described in step S3102 carries the coded data corresponding to the first DTMF key that is triggered, and thus the number of DTMF keys indicated by the carried indication information is 1.

[0164] In some embodiments, the name of the first signaling is not limited, and it can be, for example, "DTMF signaling" or the like.

[0165] In some embodiments, the network device may receive first signaling sent by the terminal.

[0166] In some embodiments, the names of signaling, information, etc. are not limited to the names described in the embodiments, and terms such as "signaling", "information", "message", "signal", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0167] Step S3103: The network device sends a confirmation message to the terminal.

[0168] In some embodiments, the network device may send an Acknowledgment (ACK) message to the terminal upon receiving the first signaling sent by the terminal.

[0169] The confirmation message may be used to indicate that the network device has received the first signaling.

[0170] In some embodiments, the name of the confirmation message is not limited, and it can be, for example, "confirmation receipt message", "confirmation receipt message", "confirmation feedback", etc.

[0171] In step S3104, the terminal caches the coded data corresponding to the DTMF key that is triggered after the first signaling is sent, until receiving a confirmation message returned by the network device.

[0172] It should be noted that since signaling transmission between the terminal and the network device takes time, especially signaling transmission in satellite communications, the transmission delay will be greater, and it will take about 3 seconds (s) for the network device to receive the first signaling sent by the terminal.

[0173] In some embodiments, after the first signaling is sent, the terminal may continue to detect the triggering of the DTMF button to timely monitor the triggering of the DTMF.

[0174] In some embodiments, when it is detected that a DTMF button is triggered, encoding can be performed based on the button information of the triggered DTMF button to obtain the encoding data corresponding to the triggered DTMF button. The implementation method can be found in step S3101 and will not be repeated here.

[0175] After the coded data are acquired, the acquired coded data may be cached so that when a sending opportunity arrives, the cached coded data may be sent to the network device at once.

[0176] Optionally, the encoded data may be cached in a buffer of the terminal, so that when a sending opportunity is reached, the cached encoded data may be obtained from the buffer for sending.

[0177] In some embodiments, terms such as "time", "duration", "period", "time window", and "window" can be replaced with each other, and terms such as "moment", "time point", "time", and "time position" can be replaced with each other.

[0178] Step S3105: The terminal continues to send the first signaling to the network device.

[0179] In some embodiments, the terminal may continue to send the first signaling to the network device after receiving the confirmation message returned by the network device. In other words, the terminal may use the confirmation message returned by the network device as a sending opportunity to continue sending the first signaling when the sending opportunity is reached.

[0180] The first signaling described in step S3105 may carry coded data corresponding to multiple triggered DTMF buttons, and the indication information carried may be used to indicate that the number of corresponding DTMF buttons is 1.

[0181] It should be noted that the above steps S3103 to S3105 can be repeated steps. Each time the terminal sends the first signaling to the network device, the network device can execute step S3103 to return a confirmation message to the terminal; in addition, each time the terminal sends the first signaling to the network device, the terminal can execute step S3104 to cache the encoded data generated after the signaling is sent, so that when the confirmation message returned by the network device is received through step S3105, the first signaling can be sent to the terminal, and the first signaling can include multiple cached encoded data.

[0182] The coded data generated after the current signaling is sent may be generated within a time period starting from the sending time of the first signaling and ending at the receiving time of the confirmation message.

[0183] Through the solution provided by the embodiment of the present disclosure, after a terminal sends a first signaling including first coded data to a network device, the coded data can be cached to send a first signaling including multiple coded data, thereby achieving the effect of sending multiple DTMF key presses at a time. For the second and subsequent first signalings, each first signaling includes coded data corresponding to multiple DTMF key presses triggered within a first time period, where the first time period starts at the time the previous first signaling is sent and ends at the time the confirmation message is received.

[0184] In some embodiments, each time the network device receives the first signaling, it may decode the received first signaling to determine the DTMF button triggered on the terminal.

[0185] In some embodiments, the network device can obtain indication information from the received first signaling to determine the number of DTMF keys corresponding to the encoded data carried by the first signaling based on the indication information, and then decode according to the determined number of DTMF keys to determine the triggered DTMF key.

[0186] Refer to Figure 4, which is a schematic diagram of a signaling interaction process according to an embodiment of the present disclosure. As shown in Figure 4, the first signaling can be DTMF signaling (DTMF signalling). When a DTMF button is triggered, the terminal can send DTMF signalling to the network device. The encoded data corresponding to the first DTMF button triggered is carried in the sent DTMF signalling in the form of a signaling PDU to send the first DTMF button triggered to the network device. After receiving the DTMF signalling, the network device can send a confirmation message (that is, DTMF signaling ACK) to the terminal.

[0187] After receiving the DTMF signaling ACK sent by the network device, the terminal can continue to send DTMF signaling to the network device. The encoded data of the second and multiple cached triggered keys are carried in the sent DTMF signaling in the form of signaling PDU to send the second and multiple triggered keys to the network device. After receiving the DTMF signaling, the network device can still send DTMF signaling ACK to the terminal.

[0188] After receiving the DTMF signaling ACK sent by the network device, the terminal can continue to send DTMF signaling to the network device. The latest cached encoded data of multiple triggered keys are carried in the sent DTMF signaling in the form of signaling PDU, so as to send the multiple keys triggered after the last signaling to the network device. After receiving the DTMF signaling, the network device can still send DTMF signaling ACK to the terminal, and so on, until the key triggering is completed.

[0189] Optionally, the network device may extract the PDU of the received DTMF signal and decode it to identify the corresponding DTMF key.

[0190] Optionally, the DTMF signal may also indicate the number of DTMF keys corresponding to the carried coded data, so that the network device will also know how many DTMF keys are received when decoding.

[0191] Through the solution provided by the embodiment of the present disclosure, the DTMF signaling process can be modified. When the upper layer performs DTMF operations, the terminal can convert the identified keys into encoded data and store it in a buffer, so that when the signaling can be sent, the encoded data can be sent to the network device as the signaling PDU content, so as to achieve the purpose of sending multiple keys at one time. The triggered multiple keys can be transmitted to the network device through two or three signals, which greatly shortens the DTMF transmission delay, reduces the occurrence of transmission failure problems caused by inputting too many keys, and increases the success rate of DTMF services.

[0192] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.

[0193] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.

[0194] In some embodiments, terms such as "certain", "preset", "preset", "setting", "indicated", "a certain", "any", and "first" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., or as specific A, a certain A, any A, or first A, etc., but not limited to this.

[0195] In some embodiments, the determination or judgment can be performed by a value represented by 1 bit (0 or 1), or by a true or false value (Boolean value) represented by true or false, or by comparison of numerical values ​​(for example, comparison with a predetermined value), but is not limited thereto.

[0196] In some embodiments, "not expecting to receive" can be interpreted as not receiving on time domain resources and / or frequency domain resources, or as not performing subsequent processing on the data after receiving it; "not expecting to send" can be interpreted as not sending, or as sending but not expecting the recipient to respond to the content sent.
