Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a voice call method and device. Background Art

[0002] During a voice call of a terminal device, the network device can enable the transmission time interval (TTI) bundling function of the terminal device. In this way, the terminal device can send multiple identical voice data packets to the network device through multiple consecutive subframes; after the network device receives the multiple identical voice data packets, it sends a positive acknowledgment (ACK) message or a negative acknowledgment (NACK) message to the terminal device; in the case where the terminal device receives an ACK message from the network device, the terminal device can continue to send subsequent voice data packets in a TTI bundling manner; in the case where the terminal device receives a NACK message from the network device, the terminal device needs to send the multiple identical voice data packets to the network device again through multiple consecutive subframes until receiving an ACK message from the network device.

[0003] However, such a voice call method may result in poor call quality of the terminal device. For example, when the base station carries too many users, voice data packet transmission is congested, resulting in the other party not being able to hear the sound, or the sound being heard being stuck, etc., resulting in a poor user experience. Summary of the invention

[0004] The present application provides a voice call method and apparatus, which are helpful to improve the voice call quality of terminal equipment, thereby improving the user experience.

[0005] In a first aspect, a voice call method is provided, comprising: a terminal device sends voice data packets to a network device in a transmission time interval TTI bundling manner; in the case of abnormal voice data packet sending, the terminal device sends a first request to the network device, the first request is used to request the network device to query the capability information of the terminal device; the terminal device receives a second request from the network device, the second request is used to request to query the capability information of the terminal device; in response to the second request, the terminal device sends first capability information to the network device, the first capability information includes first indication information, the first indication information is used to indicate that the terminal device currently does not support the TTI bundling function; the terminal device receives second indication information from the network device, the second indication information is used to instruct the terminal device to turn off the TTI bundling function; in response to the second indication information, the terminal device sends voice data packets to the network device in a non-TTI bundling manner.

[0006] In the voice call method of the present application, when the terminal device sends a voice data packet to the network device in a TTI bundling manner, if the terminal device determines that the voice data packet is sent abnormally, the network device is actively triggered to send an indication message to the terminal device for instructing the terminal device to turn off the TTI bundling function, so that the terminal device can switch from sending the voice data packet in a TTI bundling manner to sending the voice data packet in a non-TTI bundling manner after receiving the indication message. In this way, when the terminal device sends a voice packet abnormally because the scheduling resources of the network device are small and it is difficult to meet the terminal device sending the voice data packet to the network device in a TTI bundling manner, the terminal device sends the voice data packet in a non-TTI bundling manner, compared with the terminal device sending the voice data packet in a TTI bundling manner, the terminal device sends the voice data packet in a non-TTI bundling manner, and the scheduling resources of the network device that need to be occupied each time the voice data packet is sent are less. Therefore, the scheduling resources supported by the network device for the terminal device can more easily meet the terminal device's demand for scheduling resources for sending voice data packets, which helps to reduce the transmission delay of the voice data packet, thereby helping to improve the voice call quality of the terminal device and improve the user experience.

[0007] It should be understood that the voice data packet sent to the network device in a TTI bundling manner can be understood as the terminal device sending multiple redundant versions of the voice data packet through multiple consecutive uplink subframes. The first indication information can be preset information for indicating that the terminal device currently does not support the TTI bundling function, and after the network device receives the first capability information, it can determine that the terminal device currently does not support the TTI bundling function according to the first indication information included in the first capability information, thereby instructing the terminal device to turn off the TTI bundling function. The second indication information can be preset information for instructing the terminal device to turn off the TTI bundling function, and after the terminal device receives the second indication information, it can determine that the network device instructs the terminal device to turn off the TTI bundling function according to the second indication information, and continue to send voice data packets in a non-TTI bundling manner.

[0008] In certain implementations of the first aspect, after the terminal device sends the voice data packet to the network device in a non-TTI bundling manner, the method further includes: the terminal device determines whether the transmission quality of the voice data packet has improved; if the transmission quality of the voice data packet has not improved, the terminal device falls back to sending the voice data packet to the network device in a TTI bundling manner.

[0009] It should be understood that the terminal device falls back to sending voice data packets to the network device in a TTI bundling manner, which can be understood as the terminal device turning on the TTI bundling function again after determining that the transmission quality of the voice data packets has not improved, and continuing to send voice data packets to the network device in a TTI bundling manner. Since the transmission quality of the voice data packets has not improved after the terminal device switches the mode of sending voice data packets to the network device from the TTI bundling mode to the non-TTI bundling mode, the transmission quality of the voice data packets is better when the terminal device sends voice data packets to the network device in a TTI bundling mode than when sending voice data packets in a non-TTI bundling mode. It can be seen that when the transmission quality of the voice data packets has not improved, the terminal device falls back to sending voice data packets to the network device in a TTI bundling mode, which can make the transmission quality of the voice data packets fall back to at least the transmission quality when the voice data packets are sent in a TTI bundling mode, thereby helping to avoid the deterioration of the call quality of the terminal device.

[0010] In certain implementations of the first aspect, the terminal device falls back to sending voice data packets to the network device in a TTI bundling manner, including: the terminal device sends the first request to the network device again; the terminal device receives the second request from the network device; in response to the second request, the terminal device sends second capability information to the network device, the second capability information includes third indication information, and the third indication information is used to indicate that the terminal device currently supports the TTI bundling function; the terminal device receives fourth indication information from the network device, and the fourth indication information is used to instruct the terminal device to turn on the TTI bundling function; in response to the fourth indication information, the terminal device sends voice data packets to the network device in a TTI bundling manner.

[0011] It should be understood that the terminal device sending the first request to the network device again can be understood as the terminal device needs to trigger the network device to query the capability information of the terminal device again. The third indication information can be preset information for indicating that the terminal device currently supports the TTI bundling function, and after the network device receives the second capability information, it can determine that the terminal device currently supports the TTI bundling function according to the third indication information included in the second capability information. The fourth indication information can be preset information for instructing the terminal device to turn on the TTI bundling function, and after the terminal device receives the fourth indication information, it can determine that the network device indicates to turn on the TTI bundling function according to the fourth indication information.

[0012] In certain implementations of the first aspect, before the terminal device sends the second capability information to the network device, the method further includes: based on the fact that the transmission quality of the voice data packet has not improved, the terminal device updates the support status of the TTI bundling function by the terminal device to support the TTI bundling function.

[0013] It should be understood that if the transmission quality of voice data packets is not improved, the terminal device needs to fall back to sending voice data packets in TTI bundling mode. Therefore, the terminal device can first update the support status of the TTI bundling function to support the TTI bundling function. In this way, when the network device queries the capability information of the terminal device, the second capability information sent by the terminal device to the network device may include information for indicating that the terminal device currently supports the TTI bundling function (third indication information), so that the network device can send information (fourth indication information) to the terminal device based on the third indication information to instruct the terminal device to turn on the TTI bundling function, so that the terminal device can continue to send voice data packets in TTI bundling mode.

[0014] In certain implementations of the first aspect, the terminal device determines whether the transmission quality of the voice data packet has improved, including: when at least one of the following conditions is met, the terminal device determines that the transmission quality of the voice data packet has not improved: the average cache duration of the voice data packet sent in a non-TTI bundling manner within a first preset time length is greater than the average cache duration of the voice data packet sent in a TTI bundling manner within the first preset time length; the average cache duration of the voice data packet sent in a non-TTI bundling manner within the first preset time length minus the average cache duration of the voice data packet sent in a TTI bundling manner within the first preset time length is greater than a first threshold; the packet loss rate of the voice data packet sent in a non-TTI bundling manner within a second preset time length is greater than the packet loss rate of the voice data packet sent in a TTI bundling manner within the second preset time length; or, the packet loss rate of the voice data packet sent in a non-TTI bundling manner within the second preset time length minus the packet loss rate of the voice data packet sent in a TTI bundling manner within the second preset time length is greater than a second threshold.

[0015] It should be understood that the first preset duration and the second preset duration may be preset positive values, such as 1 minute, etc. The first preset duration and the second preset duration may be the same or different. The first threshold and the second threshold may be preset positive values, such as the first threshold may be 50 ms, the second threshold may be 10%, etc.

[0016] In certain implementations of the first aspect, the method further includes: the terminal device determines whether the voice data packets sent in the TTI bundling manner are sent abnormally based on the cache duration and / or packet loss rate of the voice data packets sent in the TTI bundling manner.

[0017] It should be understood that the cache time can also be called buffer time. The longer the cache time of the voice data packet, the longer the transmission delay of the voice data packet may be. The packet loss rate can be understood as the ratio of the number of voice data packets discarded by the terminal device within a period of time to the total number of voice data packets sent by the terminal device. The higher the packet loss rate, the longer the transmission delay of the voice data packet may be. Therefore, the cache time of the voice data packet and / or the packet loss rate are related to the transmission quality of the voice data packet. The terminal device can determine whether the voice data packet sent in TTI bundling mode is abnormal through the cache time and / or packet loss rate of the voice data packet.

[0018] In certain implementations of the first aspect, the determination of whether the voice data packets sent in the TTI bundling manner are abnormally sent includes: when at least one of the following items is met, the terminal device determines that the voice data packets sent in the TTI bundling manner are abnormally sent: the average cache time of the voice data packets sent in the TTI bundling manner within a third preset time length is greater than or equal to a third threshold; and / or the packet loss rate of the voice data packets sent in the TTI bundling manner within a fourth preset time length is greater than or equal to a fourth threshold.

[0019] It should be understood that the third preset duration and the fourth preset duration are preset durations, and the third preset duration and the fourth preset duration may be the same or different. The third threshold and the fourth threshold are preset positive numbers. The average cache duration of the voice data packets sent in a TTI bundling manner within the third preset duration can be understood as the average value of the cache duration of the voice data packets sent by the terminal device in a TTI bundling manner within the third preset duration. The packet loss rate of the voice data packets sent in a TTI bundling manner within the fourth preset duration can be understood as the ratio of the number of voice data packets discarded by the terminal device within the fourth preset duration to the voice data packets sent in a TTI bundling manner.

[0020] In certain implementations of the first aspect, the determination of whether the voice data packets sent in the TTI bundling manner are sent abnormally includes: determining that the voice data packets sent in the TTI bundling manner are sent abnormally when any of the following items are met: the number of occurrences of a first event within a first time period is greater than or equal to a fifth threshold, and the first event is that the average cache duration of the voice data packets sent in the TTI bundling manner within a fifth preset time length is greater than or equal to a sixth threshold; and / or the number of occurrences of a second event within a second time period is greater than or equal to a seventh threshold, and the second event is that the packet loss rate of the voice data packets sent in the TTI bundling manner within a sixth preset time length is greater than or equal to an eighth threshold.

[0021] It should be understood that the fifth threshold and the seventh threshold are preset positive values, and the fifth threshold and the seventh threshold may be the same or different. The first time period and the second time period may be understood as preset durations, for example, the first time period may be 10 minutes, and the second time period may be 15 minutes. The first time period and the second time period may also be the entire process of the terminal device sending voice data packets in a TTI-bundled manner, that is, during the entire process of the terminal device sending voice data packets in a TTI-bundled manner, the terminal device continuously accumulates the number of occurrences of the first event and / or the number of occurrences of the second event until it is determined that the voice data packets sent in a TTI-bundled manner are abnormally sent.

[0022] In certain implementations of the first aspect, before the terminal device sends the first capability information to the network device, the method further includes: based on the abnormal sending of the voice data packet, the terminal device updates the support status of the TTI bundling function of the terminal device to not supporting the TTI bundling function.

[0023] It should be understood that in the case of abnormal voice data packet sending, the terminal device needs to switch from sending voice data packets in TTI bundling mode to sending voice data packets in non-TTI bundling mode. Therefore, the terminal device can first update the terminal device's support for the TTI bundling function to not supporting the TTI bundling function, so that the capability information of the terminal device queried by the network device includes indication information for indicating that the terminal device does not support the TTI bundling function, thereby allowing the network device to instruct the terminal device to send voice data packets in non-TTI bundling mode.

[0024] In certain implementations of the first aspect, the first request is a tracking area update TAU request, and the TAU request is used to request the network device to update the location information of the terminal device.

[0025] It should be understood that when the terminal device sends a TAU request to the network device, the network device will query the capability information of the terminal device. Therefore, when the first request is a TAU request, the terminal device can actively trigger the network device to query the capability information of the terminal device, so that when the capability information of the terminal device includes a function for indicating that the terminal device does not support the TTI bundling function, the network device can instruct the terminal device to send voice data packets in a non-TTI bundling manner. In this way, the terminal device can actively trigger the closing of the TTI bundling function, so that when the voice data packet sending is abnormal, the terminal device switches from sending voice data packets in a TTI bundling manner to sending voice data packets in a non-TTI bundling manner, thereby helping to improve the voice call quality of the terminal device.

[0026] In a second aspect, a voice call device is provided, which is used to execute the method in any possible implementation of the first aspect. Specifically, the device includes a module for executing the method in any possible implementation of the first aspect.

The processing circuit is used to receive a signal through the input circuit and transmit a signal through the output circuit, so that the processor executes the method in any possible implementation of the first aspect.

[0063] It should be understood that Figure 1 The communication system 100 shown is only an example, and the present application does not limit the specific architecture of the applicable system, nor does it limit the number and form of various devices included in each communication system.

[0064] Currently, during a voice call of a terminal device, in order to improve the success rate of the terminal device sending voice data packets, the network device may enable a transmission time interval (TTI) bundling function of the terminal device.

[0065] To facilitate understanding of the embodiments of the present application, Figures 2 to 4 The TTI bundling function and related terms involved in the embodiments of the present application are described in detail.

[0066] 1. Transmission time interval (TTI) is the basic time unit for scheduling resources. It can be used to indicate the duration of transmitting a media access control (MAC) data packet. For example, a TTI can be used to indicate that the duration of transmitting a MAC transport block is 1ms. A TTI can also be understood as a subframe, that is, each subframe is used to transmit a TB.

[0067] It can be understood that a TTI can usually be identified by a TTI index, where the TTI index can also be expressed as TTI#.

[0068] 2. Hybrid automatic repeat request (HARQ) can be understood as a function of sending a redundant version (RV) of a data packet to a network device when a data packet sent by a terminal device to a network device is not sent successfully, such as when a NACK is received from the network device.

[0069] It can be understood that the HARQ process can usually be identified by a HARQ index, where the HARQ index can also be expressed as HARQ#.

[0070] In the embodiments of the present application, various terms and English abbreviations, such as transmission time interval, TTI bundling, NACK, ACK, TAU, etc., are illustrative examples given for the convenience of description and shall not constitute any limitation to the present application. The present application does not exclude the possibility of defining other terms that can achieve the same or similar functions in existing or future protocols.

[0071] It should be understood that turning on the TTI bundling function may also be referred to as turning on the TTI bundling function or activating the TTI bundling function; turning off the TTI bundling function may also be referred to as deactivating the TTI bundling function, which is not specifically limited in the embodiments of the present application. For ease of description, the following describes the voice call method by taking turning on the TTI bundling function and turning off the TTI bundling function as examples.

[0072] Figure 2 The flowchart of a method 200 for enabling a TTI bundling function of a terminal device by a network device is shown in FIG. The method 200 is applicable to the communication system 100 and includes the following steps:

[0073] S201, the terminal device sends UE capability information to the network device, the UE capability information including indication information for indicating that the terminal device supports the TTI bundling function. Correspondingly, the network device receives the UE capability information from the terminal device.

[0074] It should be understood that the capability information of the terminal device can be sent to the network device during the process of the terminal device attaching to the network device, or it can be sent by the terminal device to the network device in other cases. This application does not specifically limit the timing and specific sending method of the terminal device sending UE capability information to the network device.

[0075] S202: The network device sends information to the terminal device to instruct the terminal device to enable the TTI bundling function. Correspondingly, the terminal device receives information from the network device to instruct the terminal device to enable the TTI bundling function.

[0076] S203: In response to the information instructing the terminal device to enable the TTI bundling function, the terminal device sends a voice data packet to the network device in a TTI bundling manner. Correspondingly, the network device receives the voice data packet from the terminal device.

[0077] Combine the following Figure 3 and Figure 4 Taking the data packet sent by the terminal device to the network device as the first voice data packet and the number of redundant versions of the voice data packet when sending the voice data packet in a TTI bundling manner as 4 as an example, the process of the terminal device sending the voice data packet in a non-TTI bundling manner and a TTI bundling manner is described in detail.

[0078] Figure 3 The following is a schematic diagram of a process in which a terminal device sends a voice data packet in a non-TTI bundling manner. Figure 3As shown, the terminal device sends RV 0 of the first voice data packet to the network device at TTI 0; when the network device fails to successfully receive RV 0 of the first voice data packet, it sends NACK to the terminal device, and correspondingly, the terminal device receives the NACK at TTI 4; then, the terminal device sends RV 1 of the first voice data packet to the network device at TTI 8; when the network device fails to successfully receive RV 1 of the first voice data packet, it sends NACK to the terminal device again, and correspondingly, the terminal device receives the NACK at TTI 12; then, the terminal device sends RV 2 of the first voice data packet to the network device at TTI 16; when the network device successfully receives RV 2 of the first voice data packet, it sends ACK to the terminal device, and correspondingly, the terminal device receives the ACK at TTI 20, then the terminal device determines that the first voice data packet is sent successfully. Among them, since at TTI 0, TTI 8 and TTI 16, the terminal device sends the redundant version of the first voice data packet, the HARQ process index identifiers corresponding to TTI 0, TTI 8 and TTI 16 are the same, that is, the HARQ process index identifiers are all 0; since at TTI 4, TTI 12 and TTI 20, the terminal device receives the NACK or ACK sent by the network device to the terminal device in response to the redundant version of the first voice data packet sent by the terminal device, the HARQ process index identifiers corresponding to TTI 4, TTI 12 and TTI 20 are the same, that is, the HARQ process index identifiers are all 4.

[0079] Figure 4 FIG. 1 is a schematic diagram of a process in which a terminal device sends a voice data packet in a TTI bundling manner. Figure 4As shown, the terminal device sends four redundant versions (RV 0, RV 1, RV 2 and RV 3) of the first voice data packet to the network device in four consecutive uplink subframes (TTI 0, TTI 1, TTI 2 and TTI 3) respectively; when the network device fails to successfully receive the four redundant versions (RV 0, RV 1, RV 2 and RV 3) of the first voice data packet, it sends a joint NACK to the terminal device, and correspondingly, the terminal device receives the NACK in TTI 7; then, the terminal device again sends four redundant versions (RV 0, RV 1, RV2 and RV 3) of the first voice data packet to the network device in four consecutive uplink subframes (TTI 16, TTI 17, TTI 18 and TTI 19); when the network device successfully receives the four redundant versions (RV 0, RV 1, RV 2 and RV 3) of the first voice data packet, it sends ACK to the terminal device, and correspondingly, the terminal device receives the NACK in TTI 23 receives the ACK, the terminal device determines that the first voice data packet is sent successfully. Among them, since at TTI 0, TTI 1, TTI 2, TTI 3, TTI 16, TTI 17, TTI 18 and TTI 19, the terminal device sends the redundant version of the first voice data packet, so the identifiers of the HARQ process indexes corresponding to TTI 0, TTI 1, TTI 2, TTI3, TTI 16, TTI 17, TTI 18 and TTI 19 are the same, that is, the identifiers of the HARQ process indexes are all 0; since at TTI 7 and TTI 23, the terminal device receives the NACK or ACK sent by the network device to the terminal device in response to the redundant version of the first voice data packet sent by the terminal device, the identifiers of the HARQ process indexes corresponding to TTI 7 and TTI 23 are the same, that is, the identifiers of the HARQ process indexes are all 7. In addition, the data packets sent or received by the terminal device from TTI 8 to TTI 15 have nothing to do with the process of the terminal device sending the first voice data packet in a TTI bundling manner. This application does not specifically limit the identifier of the HARQ process index corresponding to the data packets sent or received from TTI 8 to TTI 15.

[0080] It should be understood that Figure 3 This is only an illustrative example of the process of a terminal device sending a voice data packet in a non-TTI bundling manner. Figure 4 It is only an illustrative example of the process in which the terminal device sends voice data packets in a TTI-bundled manner. When the terminal device sends voice data packets in a non-TTI-bundled manner or a TTI-bundled manner, other time slot ratios may be used; the TTI index and HARQ process index may also use other identification information, and should not constitute any limitation to the present application.

[0081] Although sending voice data packets to the network device in a TTI bundling manner can improve the success rate of the network device receiving voice data packets and reduce the number of retransmissions of the voice data packets by the terminal device. However, since the terminal device needs to send multiple identical voice data packets to the network device in a plurality of consecutive TTIs when sending voice data packets to the network device in a TTI bundling manner, the terminal device needs more scheduling resources each time it transmits voice data packets to the network device compared to sending voice data packets to the network device in a non-TTI bundling manner. Therefore, in the case where the scheduling resources of the network device are small and it is difficult to meet the needs of the terminal device to send voice data packets to the network device in a TTI bundling manner, such as when the base station carries too many users, if the network device turns on the TTI bundling function of the terminal device, it may cause the voice data packets to be difficult to be scheduled by the network device in time, resulting in a large transmission delay of the voice data packets, which may cause the voice call quality of the terminal device to deteriorate, such as the other end cannot hear the sound, or the sound heard is stuck, etc., resulting in a poor user experience.

[0082] It should be understood that scheduling resources can be understood as wireless resources, or as time domain resources and / or frequency domain resources configured by network equipment for terminal equipment, etc. This application does not make specific limitations on this.

[0083] In order to solve the above technical problems, the present application provides a voice call method and device, which actively triggers the network device to turn off the TTI bundling function when the terminal device sends voice data packets to the network device in a TTI bundling manner, and when the voice data packets are sent abnormally, so that the terminal device can send voice data packets in a way that can be switched from the TTI bundling mode to the non-TTI bundling mode. When the scheduling resources of the network device are small and it is difficult to meet the terminal device sending voice data packets to the network device in a TTI bundling mode, the terminal device can send voice data packets to the network device in a non-TTI bundling mode. In this way, compared with the terminal device sending voice data packets to the network device in a TTI bundling mode, the terminal device needs to occupy less scheduling resources of the network device each time it sends a voice data packet, which helps to improve the voice call quality of the terminal device and improve the user experience.

[0084] Combine the following Figure 5 The voice call method of the present application is described in detail. The embodiment shown in the present application illustrates the voice call method provided by the present application from the perspective of device interaction. The specific form and quantity of each device shown therein are only examples and should not constitute any limitation on the implementation of the method provided by the present application. Below, taking the terminal device and the network device as the execution subject as an example, the voice call method of the embodiment of the present application is described in detail.

[0085] It should be understood that the terminal device can be the terminal device itself, or it can be a chip, chip system or processor that supports the terminal device to implement the voice call method, or it can be a logic module or software that can implement all or part of the terminal device; the network device can be the network device itself, or it can be a chip, chip system or processor that supports the network device to implement the voice call method, or it can be a logic module or software that can implement all or part of the network device. Please do not make specific limitations on this.

[0086] Figure 5 Schematic diagram of a flow chart of a voice call method 500 provided in an embodiment of the present application. Figure 5 As shown, the method 500 includes the following steps:

[0087] S501: The terminal device sends a voice data packet to the network device in a TTI bundling manner. Correspondingly, the network device receives the voice data packet sent from the terminal device in a TTI bundling manner.

[0088] A voice data packet can be understood as a data packet sent by a terminal device to a network device during a voice call to carry the user's voice information. A voice data packet can also be understood as a transport block (TB).

[0089] The voice data packet sent to the network device in a TTI bundling manner can be understood as the terminal device sending multiple redundant versions of the voice data packet through multiple consecutive uplink subframes. For example, assuming that the terminal device needs to send voice data packet 1 to the network device, then in the case where the terminal device sends voice data packets to the network device in a TTI bundling manner, the terminal device needs to send multiple redundant versions of voice data packet 1 to the network device. After the network device receives the voice data packet sent in a TTI bundling manner, it can soft-merge the redundant versions of the received multiple voice data packets and parse the voice data packets after the soft-merging process.

[0090] It should be understood that TTI bundling can also be called TTI binding, TTI Bundling, etc., and the embodiments of the present application do not make specific limitations on this.

[0091] S502: When the voice data packet is sent abnormally, the terminal device sends a first request to the network device, the first request is used to request or trigger the network device to query the capability information of the terminal device. Correspondingly, the network device receives the first request from the terminal device.

[0092] It should be understood that the abnormal transmission of voice data packets can also be understood as congestion in uplink transmission of voice data packets, or poor voice call quality of the terminal device. In the case of abnormal transmission of data packets other than voice data packets, the terminal device does not send the first request to the network device.

[0093] S503: In response to the first request, the network device sends a second request to the terminal device, where the second request is used to query the capability information of the terminal device. Correspondingly, the terminal device receives the second request from the network device.

[0094] Optionally, the second request may be a UE capability query request.

[0095] S504: In response to the second request, the terminal device sends first capability information to the network device, the first capability information including first indication information, the first indication information being used to indicate that the terminal device currently does not support the TTI bundling function. Correspondingly, the network device receives the first capability information from the terminal device.

[0096] The first capability information can be understood as the UE capability information of the terminal device. The first indication information is used to indicate that the terminal device currently does not support the TTI bundling function, which can be understood as the terminal device determining that the terminal device itself does not support the TTI bundling function when determining that the voice data packet is sent abnormally. Before the terminal device determines that the voice data packet is sent abnormally, during the process of sending the voice data packet in TTI bundling, the terminal device supports the TTI bundling function.

[0097] The first indication information may be preset information for indicating that the terminal device currently does not support the TTI bundling function, and after the network device receives the first capability information, it can determine that the terminal device currently does not support the TTI bundling function according to the first indication information included in the first capability information, thereby instructing the terminal device to turn off the TTI bundling function. Exemplarily, the first indication information may be UE-TTI Bundling-FALSE, UE-TTI Bundling-0, etc.

[0098] S505: The terminal device receives second indication information from the network device, where the second indication information is used to instruct the terminal device to disable the TTI bundling function. Correspondingly, the terminal device receives the second indication information from the network device.

[0099] The second indication information may be preset information for instructing the terminal device to turn off the TTI bundling function, and after the terminal device receives the second indication information, it can determine, based on the second indication information, that the network device instructs the terminal device to turn off the TTI bundling function, and continue to send voice data packets in a non-TTI bundling manner. Exemplarily, the second indication information may be TTI Bundling-FALSE, TTI Bundling-0, etc.

[0100] S506: In response to the second indication information, the terminal device sends a voice data packet to the network device in a non-TTI bundling manner. Correspondingly, the network device receives the voice data packet sent from the terminal device in a non-TTI bundling manner.

[0101] It should be understood that after the terminal device receives the second indication information, it will send the voice data packet to the network device in a non-TTI bundling manner. The non-TTI bundling manner can also be understood as a normal voice data packet sending manner, that is, when the terminal device needs to send a voice data packet to the network device, it does not need to send the voice data packet and the redundant version of the voice data packet in multiple consecutive uplink subframes, but sends the voice data packet in one uplink subframe.

[0102] The voice data packets sent by the terminal device to the network device in a non-TTI bundling manner may be voice data packets that have not been successfully sent among the voice data packets sent by the terminal device to the network device in a TTI bundling manner during the process of the terminal device executing S501. Exemplarily, in S501, the terminal device sends the first voice data packet to the network device in a TTI bundling manner, that is, the terminal device sends RV0 of the first voice data packet, RV1 of the first voice data packet, RV2 of the first voice data packet, and RV3 of the first voice data packet in four consecutive uplink subframes. If RV0 of the first voice data packet, RV1 of the first voice data packet, RV2 of the first voice data packet, and RV3 of the first voice data packet are not sent successfully, and the terminal device receives the second indication information from the network device, the terminal device continues to send the first voice data packet to the network device in a non-TTI bundling manner, that is, the terminal device sends RV0 of the first voice data packet in one uplink subframe.

[0103] The voice data packet sent by the terminal device to the network device in a non-TTI bundling manner may be a subsequent voice data packet of the voice data packet sent by the terminal device to the network device in a TTI bundling manner during the process of the terminal device executing S501. Exemplarily, in S501, the terminal device sends the first voice data packet to the network device in a TTI bundling manner, that is, the terminal device sends RV0 of the first voice data packet, RV1 of the first voice data packet, RV2 of the first voice data packet and RV3 of the first voice data packet in four consecutive uplink subframes. If RV0 of the first voice data packet, RV1 of the first voice data packet, RV2 of the first voice data packet and RV3 of the first voice data packet are sent successfully, and the terminal device receives the second indication information from the network device, the terminal device continues to send the voice data packets subsequent to the first voice data packet, such as the second voice data packet, to the network device in a non-TTI bundling manner.

[0104] In the voice call method of the present application, when the terminal device sends a voice data packet to the network device in a TTI bundling manner, if the terminal device determines that the voice data packet is sent abnormally, the network device is actively triggered to send an indication message to the terminal device for instructing the terminal device to turn off the TTI bundling function, so that the terminal device can switch from sending the voice data packet in a TTI bundling manner to sending the voice data packet in a non-TTI bundling manner after receiving the indication message. In this way, when the terminal device sends a voice packet abnormally because the scheduling resources of the network device are small and it is difficult to meet the terminal device sending the voice data packet to the network device in a TTI bundling manner, the terminal device sends the voice data packet in a non-TTI bundling manner, compared with the terminal device sending the voice data packet in a TTI bundling manner, the terminal device sends the voice data packet in a non-TTI bundling manner, and the scheduling resources of the network device that need to be occupied each time the voice data packet is sent are less. Therefore, the scheduling resources supported by the network device for the terminal device can more easily meet the terminal device's demand for scheduling resources for sending voice data packets, which helps to reduce the transmission delay of the voice data packet, thereby helping to improve the voice call quality of the terminal device and improve the user experience.

[0105] As an optional embodiment, before S502, method 500 also includes: S507, the terminal device determines whether the voice data packets sent in the TTI bundling manner are sent abnormally based on the cache length and / or packet loss rate of the voice data packets sent in the TTI bundling manner; if so, the terminal device continues to execute S502.

[0106] It should be understood that the cache time can also be called buffer time. The longer the cache time of the voice data packet, the longer the transmission delay of the voice data packet may be. The packet loss rate can be understood as the ratio of the number of voice data packets discarded by the terminal device within a period of time to the total number of voice data packets sent by the terminal device. The higher the packet loss rate, the longer the transmission delay of the voice data packet may be. Therefore, the cache time of the voice data packet and / or the packet loss rate are related to the transmission quality of the voice data packet. The terminal device can determine whether the voice data packet sent in TTI bundling mode is abnormal through the cache time and / or packet loss rate of the voice data packet.

[0107] Two specific implementations of S507 are described in detail below.

[0108] A first possible implementation: When at least one of the following items is met, the terminal device determines that the voice data packets sent in the TTI bundling manner are sent abnormally: the average cache duration of the voice data packets sent in the TTI bundling manner within a third preset time length is greater than or equal to a third threshold; and / or the packet loss rate of the voice data packets sent in the TTI bundling manner within a fourth preset time length is greater than or equal to a fourth threshold.

[0109] It should be understood that the third preset duration and the fourth preset duration are preset durations, and the third preset duration and the fourth preset duration may be the same or different. The third threshold and the fourth threshold are preset positive numbers, for example, the third threshold may be 300ms, and the fourth threshold may be 5%. The average cache duration of the voice data packets sent in a TTI bundling manner within the third preset duration may be understood as the average value of the cache duration of the voice data packets sent by the terminal device in a TTI bundling manner within the third preset duration. The packet loss rate of the voice data packets sent in a TTI bundling manner within the fourth preset duration may be understood as the ratio of the number of voice data packets discarded by the terminal device within the fourth preset duration to the voice data packets sent in a TTI bundling manner.

[0110] A first possible implementation of S507 includes three cases, which are described in detail as follows.

[0111] Case 1: The average cache duration of the voice data packets sent by the terminal device in the TTI bundling manner within the third preset duration is greater than or equal to the third threshold, and it is determined that the voice data packets sent in the TTI bundling manner are abnormally sent.

[0112] The terminal device may periodically determine whether the average cache duration of the voice data packets sent in a TTI bundling manner within a third preset duration is greater than or equal to a third threshold. Specifically, the terminal device can start a timer with a preset timing length; each time the timer is completed, start a timer with a timing length of a third preset time length; after the timer with a timing length of the third preset time length is completed, calculate the average cache duration of the voice data packets sent by the terminal device in a TTI bundling manner during the current timing of the timer with a timing length of the third preset time length, and determine whether the average cache duration is greater than or equal to a third threshold; if not, start the timer with a preset timing length again; after the timer with a timing length of the preset timing length is completed again, start the timer with a timing length of the third preset time length again, after the timer with a timing length of the third preset time length is completed, calculate the average cache duration of the voice data packets sent by the terminal device in a TTI bundling manner during the current timing of the timer with a timing length of the third preset time length, and determine whether the average cache duration is greater than or equal to the third threshold, and so on, until it is determined that the voice data packets sent in the TTI bundling manner are sent abnormally, or until an indication information is received from the network device to instruct the terminal device to turn off the TTI bundling function, and the process of determining whether the voice data packets sent in the TTI bundling manner are sent abnormally ends. Exemplarily, the third preset time length is 1s, the third threshold value is 100ms, and the preset timing length is 5s. In the process of sending voice data packets in TTI bundling, the terminal device periodically calculates the average cache time of the voice data packets sent in TTI bundling within 1s every 5s, and compares the average cache time with 100ms; if the average cache time is greater than or equal to 100ms, it is determined that the voice data packets sent in TTI bundling are abnormally sent; if the average cache time is less than 100ms, the timer is started again.

[0113] When a timer with a preset timing length is not set in the terminal device, the terminal device periodically determines whether the average cache time of the voice data packets sent in the TTI bundling manner within the third preset time length is greater than or equal to the third threshold. It can be understood that the terminal device can continuously determine whether the average cache time of the voice data packets sent in the TTI bundling manner within the third preset time length is greater than or equal to the third threshold. Exemplarily, assuming that the third preset duration is 1s, and the terminal device starts sending voice data packets in a TTI bundling manner at 10:00:00, then at 10:00:01 the terminal device calculates the first average cache duration of the voice data packets sent in a TTI bundling manner from 10:00:00 to 10:00:01, and determines whether the first average cache duration is greater than or equal to the third threshold; if not, then at 10:00:02 the terminal device calculates the second average cache duration of the voice data packets sent in a TTI bundling manner from 10:00:01 to 10:00:02, and determines whether the second average cache duration is greater than or equal to the third threshold, and so on, until it is determined that the voice data packets sent in a TTI bundling manner are abnormally sent, or until an indication message is received from the network device to instruct the terminal device to turn off the TTI bundling function.

[0114] Case 2: The packet loss rate of the voice data packets sent by the terminal device in the TTI bundling manner within the fourth preset time length is greater than or equal to the fourth threshold, and it is determined that the voice data packets sent in the TTI bundling manner are abnormally sent.

[0115] It should be understood that the implementation method of Case 2 is similar to that of Case 1, that is, in Case 2, the terminal device may also periodically determine whether the packet loss rate of the voice data packets sent in a TTI bundling manner within the fourth preset time length is greater than or equal to the fourth threshold. Please refer to the above description and will not repeat it here.

[0116] Case three: the average cache duration of the voice data packets sent by the terminal device in the TTI bundling manner within the third preset time length is greater than or equal to the third threshold; and the packet loss rate of the voice data packets sent in the TTI bundling manner within the fourth preset time length is greater than or equal to the fourth threshold, determining that the voice data packets sent in the TTI bundling manner are abnormally sent.

[0117] It should be understood that situation three is a combination of situation two and situation one. Please refer to the above description and will not be repeated here.

[0118] A second possible implementation method: When any of the following items is met, it is determined that the voice data packets sent in a TTI bundling manner are sent abnormally: the number of occurrences of the first event in the first time period is greater than or equal to the fifth threshold, and the first event is that the average cache duration of the voice data packets sent in the TTI bundling manner within the fifth preset time length is greater than or equal to the sixth threshold; and / or the number of occurrences of the second event in the second time period is greater than or equal to the seventh threshold, and the second event is that the packet loss rate of the voice data packets sent in the TTI bundling manner within the sixth preset time length is greater than or equal to the eighth threshold.

[0119] It should be understood that the fifth threshold and the seventh threshold are preset positive values, and the fifth threshold and the seventh threshold may be the same or different. The first time period and the second time period may be understood as preset durations, for example, the first time period may be 10 minutes, and the second time period may be 15 minutes. The first time period and the second time period may also be the entire process of the terminal device sending voice data packets in a TTI-bundled manner, that is, during the entire process of the terminal device sending voice data packets in a TTI-bundled manner, the terminal device continuously accumulates the number of occurrences of the first event and / or the number of occurrences of the second event until it is determined that the voice data packets sent in a TTI-bundled manner are abnormally sent.

[0120] The fifth preset duration may be the same as or different from the third preset duration in the first possible implementation mode described above; the sixth threshold value may be the same as or different from the third threshold value in the first possible implementation mode described above. The specific implementation mode of the first event may refer to the situation one in the first possible implementation mode described above, which will not be described in detail here. The sixth preset duration may be the same as or different from the fourth preset duration in the first possible implementation mode described above; the eighth threshold value may be the same as or different from the fourth threshold value in the first possible implementation mode described above. The specific implementation mode of the second event may refer to the situation two in the first possible implementation mode described above, which will not be described in detail here.

[0121] The second possible implementation of S507 includes three cases, which are described in detail as follows.

[0122] In the first case, the terminal device determines that the number of occurrences of the first event in the first time period is greater than or equal to the fifth threshold, and the first event is that the average cache duration of the voice data packets sent in the TTI bundling manner within the fifth preset time length is greater than or equal to the sixth threshold, and the voice data packets sent in the TTI bundling manner are determined to be abnormal.

[0123] When the first time period is a preset duration, during the process of sending voice data in a TTI bundling manner, the terminal device periodically accumulates the number of occurrences of the first event in the first time period before determining that the voice data packet sent in a TTI bundling manner is abnormal, and determines whether the number of occurrences of the first event is greater than or equal to the fifth threshold. Specifically, after the terminal device starts to send voice data packets in a TTI bundling manner, a timer with a timing length of the first time period is started, and the number of occurrences of the first event is accumulated; if the number of occurrences of the first event is greater than or equal to the fifth threshold before the timer with a timing length of the first time period times out, it is determined that the voice data packet sent in the TTI bundling manner is abnormal, and the timing is stopped, and the accumulation of the number of occurrences of the first event is stopped; if the number of occurrences of the first event is less than the fifth threshold when the timer with a timing length of the first time period times out, the terminal device starts the timer with a timing length of the first time period again, re-accumulates the number of occurrences of the first event, and determines whether the new number of occurrences of the first event is greater than or equal to the fifth threshold, until it is determined that the new number of occurrences of the first event is greater than the fifth threshold, or, an indication message from the network device is received to instruct the terminal device to turn off the TTI bundling function, and the process of determining whether the voice data packet sent in the TTI bundling manner is abnormal is ended.

[0124] When the first time period is a preset duration, the terminal device, in the process of sending voice data in a TTI bundling manner, only accumulates the number of occurrences of the first event in the first first time period, and determines whether the number of occurrences is greater than or equal to the fifth threshold. Specifically, after the terminal device starts to send voice data packets in a TTI bundling manner, it starts a timer with a timing length of the first time period, and accumulates the number of occurrences of the first event; if the number of occurrences of the first event is greater than or equal to the fifth threshold before the timer with a timing length of the first time period times out, it is determined that the voice data packet sent in the TTI bundling manner is abnormal, and the timing is stopped, and the accumulation of the number of occurrences of the first event is stopped; if the number of occurrences of the first event is less than the fifth threshold when the timer with a timing length of the first time period times out, it is determined that the voice data packet sent in the TTI bundling manner is not abnormal, and the timing is stopped, and the accumulation of the number of occurrences of the first event is stopped.

[0125] The first time period is the entire process of the terminal device sending voice data packets in a TTI bundling manner, that is, during the entire process of the terminal device sending voice data packets in a TTI bundling manner, the terminal device continuously accumulates the number of occurrences of the first event until it is determined that the voice data packets sent in the TTI bundling manner are abnormally sent, or until it receives indication information from the network device for instructing the terminal device to turn off the TTI bundling function, and the process of determining whether the voice data packets sent in the TTI bundling manner are abnormally sent ends.

[0126] In the second case, the terminal device determines that the number of occurrences of the second event in the second time period is greater than or equal to the seventh threshold, and the second event is that the packet loss rate of the voice data packets sent in the TTI bundling manner within the sixth preset time length is greater than or equal to the eighth threshold, and it is determined that the voice data packets sent in the TTI bundling manner are abnormal.

[0127] It should be understood that the second situation is similar to the implementation of the first situation, that is, when the second time period is a preset duration, the terminal device can periodically accumulate the number of occurrences of the second event in the second time period before determining that the voice data packet sent in the TTI bundling mode is abnormally sent during the process of sending voice data in the TTI bundling mode, and judge whether the number of occurrences of the second event in each period is greater than or equal to the fifth threshold; or, the terminal device accumulates the number of occurrences of the second event only in the first second time period during the process of sending voice data packets in the TTI bundling mode, and judges whether the number of occurrences is greater than or equal to the fifth threshold. When the second time period is the entire process of the terminal device sending voice data packets in the TTI bundling mode, during the entire process of the terminal device sending voice data packets in the TTI bundling mode, the terminal device continuously accumulates the number of occurrences of the second event until it is determined that the voice data packet sent in the TTI bundling mode is abnormally sent, or until the indication information from the network device is received to instruct the terminal device to turn off the TTI bundling function, the process of determining whether the voice data packet sent in the TTI bundling mode is abnormally sent ends. The specific implementation process of the second situation can refer to the above description, which will not be repeated here.

[0128] In the third case, the terminal device determines that the voice data packets sent in the TTI bundling manner are abnormally sent through the first event occurring a number of times within the first time period that is greater than or equal to the fifth threshold, and the first event is that the average cache duration of the voice data packets sent in the TTI bundling manner within the fifth preset time length is greater than or equal to the sixth threshold; and the second event occurring a number of times within the second time period that is greater than or equal to the seventh threshold, and the second event is that the packet loss rate of the voice data packets sent in the TTI bundling manner within the sixth preset time length is greater than or equal to the eighth threshold.

[0129] It should be understood that the third situation is a combination of the second situation and the first situation. Please refer to the above description and will not be repeated here.

[0130] As an optional embodiment, after S506, method 500 also includes: S508, the terminal device determines whether the transmission quality of the voice data packet has improved; S509, if the transmission quality of the voice data packet has not improved, the terminal device falls back to sending the voice data packet to the network device in a TTI bundling manner.

[0131] It should be understood that the terminal device falls back to sending voice data packets to the network device in a TTI bundling manner, which can be understood as the terminal device turning on the TTI bundling function again after determining that the transmission quality of the voice data packets has not improved, and continuing to send voice data packets to the network device in a TTI bundling manner. Since the transmission quality of the voice data packets has not improved after the terminal device switches the mode of sending voice data packets to the network device from the TTI bundling mode to the non-TTI bundling mode, the transmission quality of the voice data packets is better when the terminal device sends voice data packets to the network device in a TTI bundling mode than when sending voice data packets in a non-TTI bundling mode. It can be seen that when the transmission quality of the voice data packets has not improved, the terminal device falls back to sending voice data packets to the network device in a TTI bundling mode, which can make the transmission quality of the voice data packets fall back to at least the transmission quality when the voice data packets are sent in a TTI bundling mode, thereby helping to avoid the deterioration of the call quality of the terminal device.

[0132] As an optional embodiment, the method 500 further includes: if the transmission quality of the voice data packet improves, the terminal device maintains the current state.

[0133] It should be understood that if the transmission quality of voice data packets improves, it means that the way the terminal device sends voice data packets to the network device is switched from the TTI bundling method to the non-TTI bundling method, which can improve the transmission quality of voice data packets and thus improve the call quality of the terminal device. Therefore, the terminal device continues to send voice data packets in a non-TTI bundling method, thereby improving the call quality of the terminal device and improving the user experience.

[0134] The specific implementations of S508 and S509 are described in detail below.

[0135] In a possible implementation, S508 may be specifically implemented in the following manner: when at least one of the following conditions is met, the terminal device determines that the transmission quality of the voice data packet has not improved. The following describes the four conditions in detail.

[0136] Condition 1: the average buffering time of the voice data packets sent in a non-TTI bundling manner within the first preset time period is greater than the average buffering time of the voice data packets sent in a TTI bundling manner within the first preset time period.

[0137] It should be understood that the first preset duration can be a preset positive value, such as 1 minute. The voice data packet sent in a non-TTI bundling manner is a voice data packet sent by the terminal device during the execution of S506. The voice data packet sent in a TTI bundling manner refers to the voice data packet sent by the terminal device during the execution of S501. The average cache duration of the voice data packet sent in a TTI bundling manner within the first preset duration can be calculated and cached by the terminal device during the execution of S501 by the terminal device.

[0138] Since the cache duration affects the transmission delay of voice data packets, when the terminal device determines that the average cache duration of voice data packets sent in a non-TTI bundling manner within a first preset duration is greater than the average cache duration of voice data packets sent in a TTI bundling manner within the first preset duration, the terminal device can determine that after the voice data packets sent in a TTI bundling manner are switched to voice data packets sent in a non-TTI bundling manner, the transmission delay of the voice data packets increases, that is, the transmission quality of the voice data packets deteriorates.

[0139] Optionally, when the average cache duration of voice data packets sent in a non-TTI bundling manner within a first preset time period is equal to the average cache duration of voice data packets sent in a TTI bundling manner within the first preset time period, the transmission quality of the voice data packets is neither improved nor deteriorated. Therefore, the terminal device can continue to send voice data packets in a non-TTI bundling manner, so that fewer scheduling resources are used compared to switching again to sending voice data packets in a TTI bundling manner.

[0140] The average buffering time of the voice data packets sent in TTI bundling mode within the first preset time can be calculated as follows:

[0141] When the terminal device receives the second indication information and starts to send voice data packets in a TTI bundling manner, the terminal device immediately starts a timer with a timing length of the first expected duration, or starts a timer with a timing length of the first expected duration after the seventh preset duration; when the timer with a timing length of the first expected duration times out, the terminal device calculates the average cache duration of the voice data packets sent in a TTI bundling manner during the timing of the timer with a timing length of the first expected duration as the average cache duration of the voice data packets sent in a TTI bundling manner within the first preset duration. The seventh preset duration is a preset positive value, such as 1 minute.

[0142] The average buffering time of the voice data packets sent in a non-TTI bundling manner within the first preset time length can be calculated in the following way:

[0143] The first estimated duration can be understood as the third estimated duration in the first possible implementation of S507. At this time, in the process of the terminal device executing S507, when the terminal device determines that the average cache duration of the voice data packets sent in a TTI bundling manner within the third preset duration is greater than or equal to the third threshold, the terminal device caches the average cache duration greater than or equal to the third threshold. In the process of the terminal device executing S508, the average cache duration of the voice data packets sent in a non-TTI bundling manner within the first preset duration can be the average cache duration greater than or equal to the third threshold cached by the terminal device.

[0144] The first estimated duration can be understood as the fifth estimated duration in the second possible implementation of S507. At this time, in the process of the terminal device executing S507, when the terminal device determines that the number of occurrences of the first event is greater than or equal to the fifth threshold, the average cache duration within the fifth preset duration of each first event in multiple first events can be cached. In the process of the terminal device executing S508, the average cache duration of the voice data packet sent in a non-TTI bundling manner within the first preset duration can be the average cache duration within the largest fifth preset duration among the multiple first events cached by the terminal device; it can also be the average cache duration within the smallest fifth preset duration among the multiple first events cached by the terminal device; it can also be the average value of the average cache duration within the fifth preset duration among the multiple first events cached by the terminal device. Exemplarily, the first event occurs three times, and the average cache times within the fifth preset time lengths of the three first events are 200ms, 180ms and 220ms respectively. Then, the average cache time of the voice data packets sent in a non-TTI bundling manner within the first preset time length can be the smallest average cache time within the fifth preset time length of the three first events (180ms); it can also be the largest average cache time within the fifth preset time length of the three first events (220ms); it can also be the average value of the average cache times within the fifth preset time lengths of the three first events (200ms).

[0145] Condition 2: the average cache duration of voice data packets sent in a non-TTI bundling manner within the first preset duration minus the average cache duration of voice data packets sent in a TTI bundling manner within the first preset duration is greater than the first threshold.

[0146] The first threshold is a preset positive value. When the value of the average cache duration of the voice data packets sent in a non-TTI bundling manner within the first preset time period minus the average cache duration of the voice data packets sent in a TTI bundling manner within the first preset time period is greater than the first threshold, it means that compared with the voice data packets sent in a TTI bundling manner, the voice data packets sent in a non-TTI bundling manner have a larger transmission delay, and therefore, the terminal device can determine that the transmission quality of the voice data packets has not improved.

[0147] It should be understood that the calculation method of the average cache time of the voice data packets sent in a non-TTI bundling manner within the first preset time length and the average cache time of the voice data packets sent in a TTI bundling manner within the first preset time length is similar to the calculation method in condition one. Please refer to the description above and will not be repeated here.

[0148] Condition three: the packet loss rate of the voice data packets sent in a non-TTI bundling manner within the second preset time length is greater than the packet loss rate of the voice data packets sent in a TTI bundling manner within the second preset time length.

[0149] It should be understood that the second preset time length can be a preset positive value, such as 1min, etc. When the cache time length of the voice data packet is greater than or equal to the preset packet loss time length, the terminal device will discard the voice data packet; in addition, after the terminal device discards the voice data packet, it is necessary to retransmit the voice data packet. Therefore, a large packet loss rate can also be understood as a large transmission delay of the voice data packet. Therefore, when the terminal device determines that the packet loss rate of the voice data packet sent in a non-TTI bundling manner within the second preset time length is greater than the packet loss rate of the voice data packet sent in a TTI bundling manner within the second preset time length, the terminal device can determine that after the voice data packet sent in a TTI bundling manner is switched to a voice data packet sent in a non-TTI bundling manner, the transmission delay of the voice data packet increases, that is, the transmission quality of the voice data packet deteriorates.

[0150] Optionally, when the packet loss rate of voice data packets sent in a non-TTI bundling manner within a second preset time length is equal to the packet loss rate of voice data packets sent in a TTI bundling manner within the second preset time length, the transmission quality of the voice data packets is neither improved nor deteriorated. Therefore, the terminal device can continue to maintain the voice data packets sent in a non-TTI bundling manner, so that fewer scheduling resources are used compared to switching again to voice data packets sent in a TTI bundling manner.

[0151] The packet loss rate of the voice data packets sent in a TTI bundling manner within the second preset time length can be calculated in the following way:

[0152] When the terminal device receives the second indication information and starts to send voice data packets in a TTI bundling manner, the terminal device immediately starts a timer with a timing length of the second expected duration, or starts a timer with a timing length of the second expected duration after the eighth preset duration; when the timer with a timing length of the second expected duration times out, the terminal device calculates the packet loss rate of the voice data packets sent in a TTI bundling manner during the timing of the timer with a timing length of the second expected duration as the packet loss rate of the voice data packets sent in a TTI bundling manner within the second preset duration. The eighth preset duration is a preset positive value, such as 1 minute.

[0153] The packet loss rate of the voice data packets sent in a non-TTI bundling manner within the second preset time period can be calculated in the following way:

[0154] The second estimated duration can be understood as the fourth estimated duration in the first possible implementation of S507. At this time, when the terminal device executes 507, when the packet loss rate of the voice data packets sent by the terminal device in a TTI bundling manner within the fourth preset duration is greater than or equal to the fourth threshold, the terminal device caches the packet loss rate greater than or equal to the fourth threshold; when the terminal device executes S508, the packet loss rate of the voice data packets sent in a non-TTI bundling manner within the second preset duration can be the packet loss rate greater than or equal to the fourth threshold cached by the terminal device.

[0155] The second estimated duration can also be understood as the sixth estimated duration in the second possible implementation of S507. At this time, during the process of the terminal device executing 507, when the terminal device determines that the number of occurrences of the second event is greater than or equal to the seventh threshold, the terminal device caches the packet loss rate within the sixth preset duration of multiple second events; during the process of the terminal device executing 508, the voice data packet sent in a non-TTI bundling manner can be the packet loss rate within the sixth preset duration of the largest of the multiple second events cached by the terminal device; it can also be the packet loss rate within the sixth preset duration of the smallest of the multiple second events cached by the terminal device; it can also be the average packet loss rate within the sixth preset duration of multiple second events cached by the terminal device. Exemplarily, the second event occurs three times, and the packet loss rates of the three second events within the sixth preset time period are 20%, 18% and 22% respectively. Then, the packet loss rate of the voice data packet sent in a non-TTI bundling manner within the second preset time period can be the smallest packet loss rate within the sixth preset time period among the three second events (18%); it can also be the largest packet loss rate within the sixth preset time period among the three second events (22%); it can also be the average packet loss rate within the sixth preset time period of the three second events (20%).

[0156] Condition 4: the packet loss rate of voice data packets sent in a non-TTI bundling manner within a second preset time length minus the packet loss rate of voice data packets sent in a TTI bundling manner within the second preset time length is greater than the second threshold.

[0157] The second threshold is a preset positive value. When the packet loss rate of the voice data packets sent in a non-TTI bundling manner within the second preset time length minus the packet loss rate of the voice data packets sent in a TTI bundling manner within the second preset time length is greater than the second threshold, it means that compared with the voice data packets sent in a TTI bundling manner, the voice data packets sent in a non-TTI bundling manner have a larger transmission delay, and therefore, the terminal device can determine that the transmission quality of the voice data packets has not improved.

[0158] It should be understood that the calculation method of the packet loss rate of the voice data packets sent in a non-TTI bundling manner within the second preset time length and the packet loss rate of the voice data packets sent in a TTI bundling manner within the second preset time length is similar to the calculation method in condition three. Please refer to the description above and will not be repeated here.

[0159] In a possible implementation, S509 can be specifically implemented in the following manner: the terminal device sends a first request to the network device again; the terminal device receives a second request from the network device; in response to the second request, the terminal device sends second capability information to the network device, the second capability information includes third indication information, and the third indication information is used to indicate that the terminal device currently supports the TTI bundling function; the terminal device receives fourth indication information from the network device, and the fourth indication information is used to instruct the terminal device to turn on the TTI bundling function; in response to the fourth indication information, the terminal device sends voice data packets to the network device in a TTI bundling manner.

[0160] The terminal device sending the first request to the network device again can be understood as the terminal device needs to trigger the network device to query the capability information of the terminal device again. The first request sent to the network device again can be the same as the first request sent by the terminal device in S502. The third indication information can be preset information for indicating that the terminal device currently supports the TTI bundling function, and after the network device receives the second capability information, it can determine that the terminal device currently supports the TTI bundling function according to the third indication information included in the second capability information. Exemplarily, the third indication information can be UE-TTIBundling-TRUE, UE-TTI Bundling-1, etc. The fourth indication information can be preset information for instructing the terminal device to turn on the TTI bundling function, and after the terminal device receives the fourth indication information, it can determine that the network device indicates to turn on the TTI bundling function according to the fourth indication information. Exemplarily, the fourth indication information can be TTI Bundling-TRUE, TTIBundling-1, etc.

[0161] It should be understood that the specific implementation of the above S509 is similar to that of S502 to S506, which will not be described in detail here, and reference may be made to the above description.

[0162] In a possible implementation, in the above-mentioned S509 specific implementation, before the terminal device sends the second capability information to the network device, method 500 also includes: based on the fact that the transmission quality of the voice data packet has not improved, the terminal device updates the terminal device's support for the TTI bundling function to support the TTI bundling function.

[0163] It should be understood that if the transmission quality of voice data packets is not improved, the terminal device needs to fall back to sending voice data packets in TTI bundling mode. Therefore, the terminal device can first update the support status of the TTI bundling function to support the TTI bundling function. In this way, when the network device queries the capability information of the terminal device, the second capability information sent by the terminal device to the network device may include information for indicating that the terminal device currently supports the TTI bundling function (third indication information), so that the network device can send information (fourth indication information) to the terminal device based on the third indication information to instruct the terminal device to turn on the TTI bundling function, so that the terminal device can continue to send voice data packets in TTI bundling mode.

[0164] As an optional embodiment, before S505, the method 500 further includes: based on the abnormal transmission of the voice data packet, the terminal device updates the support status of the TTI bundling function of the terminal device to not supporting the TTI bundling function.

[0165] It should be understood that in the case of abnormal voice data packet sending, the terminal device needs to switch from sending voice data packets in TTI bundling mode to sending voice data packets in non-TTI bundling mode. Therefore, the terminal device can first update the terminal device's support for the TTI bundling function to not supporting the TTI bundling function, so that the capability information of the terminal device queried by the network device includes indication information for indicating that the terminal device does not support the TTI bundling function, thereby allowing the network device to instruct the terminal device to send voice data packets in non-TTI bundling mode.

[0166] As an optional embodiment, the first request is a tracking area update (TAU) request, and the TAU request is used to request the network device to update the location information of the terminal device.

[0167] It should be understood that when the terminal device sends a TAU request to the network device, the network device will query the capability information of the terminal device. Therefore, when the first request is a TAU request, the terminal device can actively trigger the network device to query the capability information of the terminal device, so that when the capability information of the terminal device includes a function for indicating that the terminal device does not support the TTI bundling function, the network device can instruct the terminal device to send voice data packets in a non-TTI bundling manner. In this way, the terminal device can actively trigger the closing of the TTI bundling function, so that when the voice data packet sending is abnormal, the terminal device switches from sending voice data packets in a TTI bundling manner to sending voice data packets in a non-TTI bundling manner, thereby helping to improve the voice call quality of the terminal device.

[0168] As an optional embodiment, before S502, method 500 also includes: determining whether the TTI bundling function is in an on state; S502 is specifically implemented in the following manner: when the TTI bundling function is in an on state, the terminal device sends a first request to the network device.

[0169] In a possible implementation, determining whether the TTI bundling function is in an on state can be specifically implemented in the following manner: determining whether the identifier of the TTI bundling function cached by the terminal device is a first identifier, the identifier of the TTI bundling function includes a first identifier and a second identifier, wherein the first identifier indicates that the TTI bundling function is in an on state, and the second identifier indicates that the TTI bundling function is in an off state; when the identifier of the TTI bundling function is the first identifier, determining that the TTI bundling function is in an on state. Exemplarily, the first identifier may be TTI Bundling-1, and the second identifier may be TTIBundling-0.

[0170] As an optional embodiment, the second indication information is a radio resource control (RRC) connection establishment message, and the RRC connection establishment message includes information for instructing the terminal device to turn off the TTI bundling function.

[0171] As an optional embodiment, before S501, method 500 also includes: the network device determines whether the signal to interference plus noise ratio (SINR) of the voice data packet received from the terminal device is lower than a first threshold value; if so, sends a third request for requesting a power headroom report (PHR) to the terminal device; the terminal device sends the PHR to the network device in response to the third request; if the network device determines that the power headroom of the terminal device is lower than the second threshold value, it determines that the channel quality of the terminal device is poor; in the case of poor channel quality of the terminal device, the network device sends a fifth indication information to the terminal device for instructing the terminal device to send voice data packets in a TTI bundling manner; S501 is specifically implemented in the following manner: the terminal device sends the voice data packet in a TTI bundling manner in response to the fifth indication information.

[0172] It should be understood that the order of execution of the above methods does not necessarily mean the order in which they are executed. The order in which each process is executed should be determined by its function and internal logic.

[0173] Combination of the above Figure 5 , describes in detail the voice call method of the embodiment of the present application, and the following is combined with Figure 6 and Figure 7 , the voice call device of the embodiment of the present application is described in detail.
