[0071] In terrestrial network (TN) voice solutions, traditional Voice over Long-Term Evolution (VOLTE) voice bearers sample voice data every 20 milliseconds (ms) and transmit it via semi-static / semi-permanent scheduling (SPS) at base stations. With the development of NTN, IoT NTN can be used to implement IMS voice calls, including both high-latency and low-latency packet formats. For example... Figure 1 As shown, large-latency packets are assembled into data packets with a time interval of 500ms, and may even be assembled into data packets with a time interval of 1 second. A large number of voice samples are combined into a single data packet for transmission, resulting in low header overhead. This can be transmitted on either anchor or non-anchor carriers. For example... Figure 2 As shown, the hourly delay packets are composed of 80ms each, or even smaller, and can be scheduled using SPS. The one-way voice delay is small, approaching the 400ms one-way voice delay defined by the International Telecommunication Union (ITU), and is close to the performance of the Geostationary Synchronous Orbit-Mobile Radio-1 (GMR-1), which is closer to the performance of Tiantong or Maritime.

[0072] For high-latency packet assembly, the one-way voice latency is large, far exceeding the ITU-defined 400ms one-way voice latency. Combined with core network latency, this can lead to occasional short-distance intercoms, and packet loss has a significant impact. For low-latency packet assembly, a small number of voice samples are combined into a single data packet for transmission, resulting in large header overhead, high network resource consumption, and complex network scheduling. Due to frequent data scheduling and transmission, downlink control information (DCI) is used, and scheduling the narrowband physical downlink control channel (NPDCCH) incurs extremely high overhead.

[0073] Existing voice call solutions have their terminal voice sampling and packet assembly methods and base station scheduling modes fixed during the initial configuration process, meaning they can only operate according to these predetermined methods. However, in real-world applications, user needs for voice services are dynamic, and existing configuration methods cannot meet the changing demands of real-world voice scenarios.

[0074] Based on this, in various embodiments of this application, the first network device of NTN determines a first value of the first terminal based on first information, or determines a first value of the first terminal and a first value of the second terminal based on second information; wherein, the first information at least indicates the remaining available resources of the first network device; the second information at least indicates the theoretical capacity of a first cell of the first network device corresponding to one or more candidate first values, one first value corresponds to one voice packetization method, the first cell represents the cell where the first terminal accesses the first network device, and the second terminal includes some or all terminals other than the first terminal that access the first cell. With the above scheme, the first network device can adjust the voice packetization method of the terminal according to the remaining available resources of the first network device, or adjust the voice packetization method of the terminal according to the theoretical capacity of the cell where the terminal accesses the first network device, thereby improving the flexibility of voice packetization and enabling the packetization method to match the changing needs in real voice scenarios, thus improving the capacity of NTN voice services.

[0075] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0076] First, the overall interaction flow of the voice communication method according to the embodiments of this application will be described. The overall interaction flow of the voice communication method includes... Figure 3 The voice communication flow shown is a semi-static adjustment of the voice packet grouping method, and Figure 4 The voice communication process is shown by dynamically adjusting the voice packet method.

[0077] like Figure 1As shown, the voice communication process using the semi-static adjustment voice packet method includes the following steps:

[0078] Step 1: The first terminal of the first network device connected to NTN initiates a voice call.

[0079] Here, a first terminal connected to the first network device of the NTN initiates a voice call to a third terminal. The first terminal can be understood as the calling terminal or calling user; the third terminal can be understood as the called terminal or called user. The cell where the first terminal connects to the first network device is called the first cell, and multiple terminals can connect to the first cell. NTN network equipment may include one or more of the following: base stations, NTN base stations, access network equipment, and Radio Access Network (RAN) equipment.

[0080] Step 2: The first network device of NTN determines whether there exists n that satisfies T. n ≥x n +t 占 .

[0081] Here, n represents the first value, and n is an integer greater than or equal to 1; in practical applications, a set of alternative n values ​​can be set. n The speech packet period is represented by the smallest packet period of α milliseconds (ms) and the first value is n. n It equals n×α, that is, T n = n × α. x n Characterizing the first time-domain resource, the candidate first time-domain resources include, but are not limited to, one or more of 18, 28, and 48; x n To determine the temporal resources occupied by a single voice packet scheduling operation based on theoretical calculations using n×α milliseconds as the packet grouping method, this application embodiment determines x based on n and α. n The calculation method is not restricted, in (n×α) and x n There is a correspondence between them, meaning that once n and α are determined, x can be uniquely determined or calculated. n . t 占 Characterizing the second time-domain resource, t 占 =∑ i x ni The method of grouping packages is also called the package model.

[0082] The first network device of the NTN determines or calculates whether there exists n that satisfies T. n ≥x n +t 占 Or determine or calculate that satisfies T n ≥x n +t 占 The minimum value of n (the first value). Specifically:

[0083] 1) Select the smallest n from the candidates n, that is, choose n from the candidates n. min ,calculate and t 占 And determine whether it meets the requirements. If satisfied Then jump to step 3 and take n. MO =n min ;

[0084] 2) If Then using n min+1 calculate and t 占 And determine whether it meets the requirements. If satisfied Then jump to step 3 and take n. MO =n min +1.

[0085] 3) Continue this calculation to obtain the minimum n. MO ;exist In this case, the system will jump to the voice communication process that dynamically adjusts the voice packet method.

[0086] It should be noted that the smallest n MO It can be understood as the smallest first value.

[0087] Step 3: The first network device records that T satisfies n ≥x n +t 占 The minimum value of n is denoted as n, where n is the bearer corresponding to the first terminal and the corresponding minimum value of n. MO .

[0088] Step 4: The first network device will obtain n MO Inform the core network.

[0089] Step 5: The core network transmits the n of the first terminal through the second network device of NTN. MO Inform the third terminal.

[0090] Here, the core network will use the n of the first terminal. MO The second network device of NTN is informed, and the second network device of NTN will transmit the n of the first terminal. MO Inform the third terminal. The third terminal represents the terminal that conducts voice calls with the first terminal; that is, the third terminal can be understood as the called terminal or the called user.

[0091] Step 6: The second network device of NTN accessed by the third terminal determines whether its remaining available resources are sufficient for the third terminal to access voice services.

[0092] Here, the NTN's second network device determines whether its remaining available resources meet the resource requirements of the third terminal's voice service. In other words, the NTN's second network device determines whether the cell accessed by the third terminal has an n value that satisfies T. n ≥x n +t 占 The details are as follows:

[0093] 1) Select the smallest n from the candidates n, that is, choose n from the candidates n. min ,calculate and t 占 And determine whether it meets the requirements. If satisfied Then jump to step 7 and take n. MT =n min ;

[0094] 2) If Then using n min+1 Calculate and t 占 And determine whether it meets the requirements. If satisfied Then jump to step 7 and get n. MT =n min +1.

[0095] 3) Continue this calculation to obtain the minimum n. MT ;exist In this case, the system will jump to the voice communication process that dynamically adjusts the voice packet method.

[0096] Step 7: The second network device record of NTN satisfies T n ≥x n +t 占 The minimum value of n is denoted as n, where n is the bearer corresponding to the third terminal and the corresponding minimum value of n. MT .

[0097] Step 8: NTN's second network device comparison n MO and n MT If n MO ≥n MT Then take n f =n MO If n MO <n MT Then take n f =n MT .

[0098] Step 9: NTN's second network device records n f For the new nMT That is, the n recorded by the second network device MT Updated to n f .

[0099] Step 10: The second network device of NTN will calculate n f Periodically notify the core network and third-party terminals.

[0100] Step 11: The core network will... f Inform the first network device and the first terminal of NTN.

[0101] It should be noted that the first terminal and the third terminal obtain n f In the case of n, according to the updated n f Values ​​are used as packet assembly methods for voice services; the first and second network devices of the NTN can use T = min(n f ,n 原有用户 )×α is used as the scheduling model to schedule speech packets. T=min(n f ,n 原有用户 )×α can be understood as the first scheduling cycle.

[0102] It should be noted that, in Figure 3 In steps 2 and 6, if the calculation This requires triggering a voice communication process that dynamically adjusts the voice packet composition method.

[0103] like Figure 4 As shown, the voice communication process that dynamically adjusts the voice packetization method includes the following steps:

[0104] Step 1: The first network device of NTN determines whether there exists a value of m that satisfies m≤Y based on the estimated number of users m of the first cell. n The estimated number of users in the first community is equal to the sum of the current number of users and the number of new users.

[0105] Here, Y n This represents the cell capacity or theoretical capacity when using voice packet grouping method n; it can be determined based on the voice packet period and x. n Determine Y n For example, the period of the voice packet can be compared with x. n The quotient is rounded down to obtain Y. n .

[0106] If there exists a value of n that satisfies m≤Y n Then, the smallest n value that satisfies the equation is selected as n. f Proceed to step 2. If there is no value of n that satisfies m ≤ Y n Then, no adjustments to the process are needed, and the process can be completed.

[0107] Step 2: The first network device of NTN will n f Inform the core network and all terminals accessing the first cell.

[0108] Step 3: The core network will... f Inform the second network device of NTN and all terminals connected to the first network device of NTN.

[0109] It should be noted that NTN's second network device can also perform this function. Figure 4 The process shown is as follows: Figure 4 The first and second network devices in the system can be interchanged.

[0110] The following examples will illustrate this.

[0111] For example, in an industry implementing a 20ms voice sampling period, i.e., α = 20, based on the terminal implementation, the first value for the voice packetization method includes three types: 80ms, 120ms, and 500ms, i.e., n = 4, 6, and 25, respectively. The corresponding x values ​​are... n The values ​​are 18, 28, and 48.

[0112] like Figure 5 As shown, user a initiates a voice call to user b at base station A, and user b connects to a cell of base station B. It is known that there is already a voice user 2 in this cell of base station A, using a 500ms voice packet grouping method, α = 20ms, n = 25, and a single voice packet scheduling takes 48ms. There is also a voice user 2 in cell of base station B, which also uses the 500ms voice packet grouping method.

[0113] Based on the overall interaction flow of the voice communication method shown in the above embodiments, this application will describe the embodiments using the first network device and the terminal (including the first terminal and / or the third terminal) of the NTN as the execution subjects. It should be noted that the implementation principle of the voice communication method with a single execution subject can be understood in the same way as the relevant content of the overall interaction flow embodiment of the voice communication method described above, and will not be repeated below.

[0114] This application provides a voice communication method applied to a first network device of an NTN. For example... Figure 6 As shown, the method includes:

[0115] Step 601: Determine the first value of the first terminal based on the first information, or determine the first value of the first terminal and the first value of the second terminal based on the second information.

[0116] Wherein, the first information at least indicates the remaining available resources of the first network device; the second information at least indicates the theoretical capacity of the first cell of the first network device corresponding to one or more candidate first values, one first value corresponds to one voice packet grouping method, the first cell represents the cell where the first terminal accesses the first network device, and the second terminal includes some or all terminals other than the first terminal that access the first cell.

[0117] Here, the first network device of NTN acquires or determines first information, and determines the first value of the first terminal based on the first information to obtain the voice packetization method of the first terminal; or, it acquires second information, and determines the first value of the first terminal and the first value of the second terminal based on the second information to obtain the voice packetization method of the first terminal and the voice packetization method of the second terminal. The first network device of NTN can obtain the second information from a local database, or from a non-local database (e.g., a cloud database, a cloud server, etc.) or from other devices or network functions. The first value of the first terminal and the first value of the second terminal can be the same or different. The first value can be represented by n, where n is an integer greater than or equal to 1. In practical applications, a set of alternative n values ​​can be set. The second information can be represented by Y. n This indicates that voice services include voice calls. Theoretical capacity can be simply referred to as capacity.

[0118] To improve the efficiency and accuracy of determining the first value, in one embodiment, the first information includes one or more of the following:

[0119] One or more candidate speech packet cycles, where a speech packet cycle represents the product of a first value and a minimum number of packet cycles;

[0120] One or more candidate first time-domain resources, where the first time-domain resource represents the time-domain resources occupied by a scheduled speech packet;

[0121] The second time-domain resource represents the sum of time-domain resources occupied by a single scheduling voice packet of all second terminals in the first cell.

[0122] Here, the voice packet period can be T or To. n The smallest packet period can be represented by α; when the first value is represented by n, the speech packet period is equal to n × α. The first time-domain resource can be represented by x. n This indicates that the candidate first time-domain resources include, but are not limited to, one or more of 18, 28, and 48. The second time-domain resource can be represented by t. 占 express,

[0123] It should be noted that, depending on the implementation method, the minimum sampling packet period for voice is αms. The terminal side can superimpose n minimum packets to form a large-delay packet and transmit it as a single frame of voice data. That is, n × α milliseconds constitute one frame of voice data. n To determine the temporal resources occupied by a single speech packet scheduling based on a theoretically calculated packet grouping model of n×α milliseconds, this application embodiment defines x based on nα. n The calculation method is not restricted. Taking a 500ms large packet as an example, α = 20ms, n = 25, downlink is restricted, and the downlink control information (DCI) scheduling method under the current Physical Downlink Control Channel (PDCCH) is adopted. Based on the signal-to-interference plus noise ratio (SINR), modulation and coding scheme (MCS), and repetition count, the downlink takes up 40ms. Adding the time occupied by two DCIs (4 + 4 = 8ms), the total time occupied by one voice packet scheduling is 48ms, i.e., x n =48ms, the scheduling period is equal to the voice packet period T = n × α = 500ms, Y n Let n be the cell capacity when using voice packet grouping method, i.e. It can be seen that, due to the uniform configuration of the scheduling period for network devices, when there are different packet sizes within the same cell, scheduling must be performed according to the minimum packet period to meet the latency requirements, i.e., T = n min ×α. When a terminal or user in the cell initiates a voice service, the network device triggers a semi-static adjustment of the voice packet composition method for the voice communication process. The network device can establish or identify the type of Radio Resource Control (RRC) connection establishment cause through the dedicated voice bearer, such as emergency call or high priority access, as a decision trigger condition. Other identifiers can also be set according to actual needs for decision-making.

[0124] To improve the efficiency of determining the first value, in one embodiment, the second information includes one or more of the following:

[0125] The theoretical capacity of the first cell corresponds to one or more candidate first values, the first value indicates the voice packet grouping method, and the theoretical capacity of the first cell is determined based on the voice packet period and the first time domain resources;

[0126] One or more candidate speech packet cycles, where a speech packet cycle represents the product of a first value and a minimum number of packet cycles;
