[0091] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0092] I. Call setup process.

[0093] The process of user equipment 1 initiating an IP Multimedia Subsystem (IMS) voice call is shown in Figure 2. User equipment 1 connects to the gNB via satellite and further connects to the IMS network element. The voice call establishment process includes:

[0094] Step 201: Establish a Protocol Data Unit (PDU) session, which is used to transmit IMS services.

[0095] Step 202: User equipment 1 initiates an IMS call establishment request by sending an Invite message 1 using Session Initiation Protocol (SIP) and carrying information about the voice media to be established in the requested Session Description Protocol (SDP).

[0096] Examples of SDP are as follows:

[0097] m = audio 0RTP / AVP 97;

[0098] a = rtpmap:97AMR / 8000 / 1.

[0099] The m-line can be called the media line, representing the type of media as voice service;

[0100] Row 'a' can be called the attribute row, representing the attribute information of this voice service.

[0101] In this context, "97" represents the Real-time Transport Protocol (RTP) payload type, "AMR" indicates that the encoding format is Adaptive Multi-Rate Narrowband (AMR-NB), "8000" represents the sampling rate, and "1" represents mono.

[0102] Step 203: The Session Border Controller (SBC) / P-CSCF sends the invite message 1 to the S-CSCF.

[0103] Optionally, P-CSCF and S-CSCF in Figure 2 are both IMS network elements that provide services to user equipment 1, while IMS network elements that provide services to user equipment 2 are not shown.

[0104] Optionally, the SBC is an important network node in the IMS network, located at the IMS network boundary, playing a crucial role in connecting user equipment to the IMS core network. Its main functions include access permission control, network topology hiding, Network Address Translation (NAT) and NAT traversal, Quality of Service (QoS), and bandwidth policy adjustment. The SBC can include both a control plane and a user plane, or the control plane and user plane can be separated; for example, the SBC control plane (SBC-C) is used for control, and the SBC user plane (SBC-User plane) is used for transmitting media data.

[0105] Optionally, SBC / P-CSCF represents an IMS network element that includes both SBC and P-CSCF functions, such as an SBC that includes P-CSCF functions, or an IMS network element that combines SBC and P-CSCF.

[0106] Step 204: The S-CSCF sends invite message 1 to the application server (AS) that provides services to user equipment 1.

[0107] Step 205: AS sends the processed invite message 1 to S-CSCF, that is, AS processes invite message 1 and sends it back to S-CSCF.

[0108] Step 206: The S-CSCF sends the processed invite message 1 to the user equipment 2.

[0109] Step 207: User equipment 2 replies with a 183 message (i.e., a response message), which contains information about the voice services supported by SDP provided by user equipment 2.

[0110] Optionally, if user equipment 1 provides multiple voice encoding methods in step 2, such as supporting 4.75kbps, 12.2kbps, etc., user equipment 2 will select one of its supported voice encoding methods and carry it through the SDP answer of the 183 message.

[0111] Optionally, after receiving the 183 message, the P-CSCF providing the service for user equipment 2 triggers the establishment of a dedicated QoS flow for transmitting voice services for user equipment 2, which is the same as step 211.

[0112] Step 208: S-CSCF sends Message 183 to AS. AS will process Message 183 and obtain the processed Message 183.

[0113] Step 209: AS sends the processed 183 message to S-CSCF.

[0114] Step 210: The S-CSCF sends the processed 183 message to the SBC / P-CSCF.

[0115] Step 211: The P-CSCF sends a message to the PCF of 5G based on the SDP answer to establish a dedicated QoS flow for transmitting voice services.

[0116] Step 212: After the QoS flow is established, the P-CSCF sends a 183 message to User Equipment 1.

[0117] Step 213: When user device 2 answers the call, user device 2 sends a 200 OK message. When the 200 OK message is sent to user device 1, user device 1 and user device 2 begin their call.

[0118] II. QoS flow establishment process.

[0119] The QoS flow establishment process is shown in Figure 3. Figure 3 is a detailed process of step 211 above, which specifically includes:

[0120] Step 301: After the SDP negotiation is completed, the P-CSCF sends the negotiated SDP information to the PCF.

[0121] Step 302: PCF determines the QoS parameters corresponding to the QoS flow based on the SDP information.

[0122] Step 303: The PCF sends a control policy update message (such as the Npcf_SMPolicyControl_UpdateNotify message) to the SMF, carrying the determined QoS parameters.

[0123] Step 304: Based on the information provided by the PCF, the SMF determines the new QoS flow that meets the QoS requirements. The SMF sends an N1N2 message transmission (such as Namf_Communication_N1N2MessageTransfer) message to the AMF. The N2 SM information contains the QoS parameters corresponding to the QoS flow to be established, and the N1 SM container carries a PDU session modification command to be sent to the user equipment. The PDU session modification command is used to notify the user equipment to create a new QoS flow.

[0124] Step 305: AMF sends an N2 message to the base station, carrying N2 SM information and N1 SM container.

[0125] Step 306: The base station saves the N2 SM information and configures the radio resources for the UE according to the N2 SM information. The configuration of radio resources is used to establish the DRB (data radio bearer) corresponding to the QoS flow.

[0126] The base station sends the N1 SM container to the user equipment.

[0127] Step 307: Send a response message. The sending of the response message can be referred to relevant technologies, and will not be elaborated here.

[0128] Optionally, high-speed voice can provide a better call experience, but it requires strong signal strength and is prone to dropped calls at cell edges; low-speed voice can maintain call continuity at cell edges, but the call experience is poor. Since only one voice codec can be used per call, how to select between high-speed and low-speed voice, and how to switch between them, are problems that need to be solved. Therefore, the voice bearer processing method of this application is proposed.

[0129] Optionally, low bitrate speech refers to speech coding methods with a low coding rate. Low bitrate speech typically refers to speech codecs with a coding rate of less than or equal to 2.4kbps or 1.2kbps. Low bitrate speech can also be understood or replaced with low bitrate speech codec, ultra-low bitrate speech, ultra-low bitrate speech codec, narrowband codec speech, or narrowband speech.

[0130] The voice processing method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0131] Referring to attitude 4, this application embodiment provides a voice bearer processing method, as shown in Figure 4, which includes:

[0132] Step 401, the first network entity performs a first operation, the first operation including any of the following:

[0133] Once the user equipment has established the first voice bearer, the first information is sent to the second network entity.

[0134] When the user equipment establishes a second voice bearer, it receives second information from the second network side entity and determines the first quality of service (QoS) parameter corresponding to the first voice code based on the second information.

[0135] Wherein, the first voice bearer supports a first QoS parameter corresponding to the first voice codec and a second QoS parameter corresponding to the second voice codec, and the first information is used to indicate at least one of the following: the network can meet the first QoS parameter; the network can meet the transmission rate; switch to the first voice codec; switch voice codec;

[0136] Wherein, the second voice bearer supports the second QoS parameter corresponding to the second voice code, and the second information is used to indicate at least one of the following: switching voice code; switching to the first voice code; switching the parameters of the voice code; switching to the first QoS parameter.

[0137] In this embodiment, the first network entity can be a PCF, and the second network entity can be a P-CSCF. The first and second speech codes are different; for example, their coding rates are different.

[0138] Optionally, the aforementioned first or second information can be used to indicate that the network needs to switch, or that the user equipment has already switched, or that the user equipment needs to switch. For example, indicating a switch to the first voice coding can be understood as indicating that the network needs to switch to the first voice coding, or that the user equipment has already switched to the first voice coding, or that the user equipment needs to switch to the first voice coding. Switching voice coding can be understood as the network needing to switch voice coding, or that the user equipment has already switched voice coding, or that the user equipment needs to switch voice coding. The parameters for switching voice coding can be understood as the parameters for which the network needs to switch voice coding, or the parameters for which the user equipment has already switched voice coding, or the parameters for which the user equipment needs to switch voice coding. Switching to the first QoS parameter can be understood as the network needing to switch to the first QoS parameter.

[0139] It should be noted that the speech encoding in this application can be understood or replaced as speech codec, or speech codec. The same applies thereafter, and will not be repeated hereafter.

[0140] Optionally, the aforementioned first voice bearer supporting the first QoS parameter corresponding to the first voice code and the second QoS parameter corresponding to the second voice code can be understood as follows: when transmitting data based on the first voice code using the first voice bearer, the first QoS parameter can be satisfied. In some embodiments, the first voice bearer can be understood as a voice bearer that supports both the first and second voice codes.

[0141] Optionally, the second voice bearer supporting the second QoS parameters corresponding to the second voice codec can be understood as the second voice bearer only supporting the second QoS parameters corresponding to the second voice codec, or the second voice bearer supporting the second QoS parameters corresponding to the second voice codec but not supporting the first QoS parameters corresponding to the first voice codec. In some embodiments, the first voice bearer can be understood as a voice bearer that supports the second voice codec, or as a voice bearer that supports the second voice codec but does not support the first voice codec.

[0142] Optionally, in some embodiments, when the user equipment has established a first voice bearer, a first operation can be performed if the first network entity determines that a voice coding switch is needed. For example, a first message can be sent to a second network entity, enabling the second network entity to notify a fifth network entity (e.g., an AGW) to initiate the first voice coding based on the first message. It should be understood that before the fifth network entity initiates the first voice coding, the fifth network entity communicates with the user equipment based on the second voice coding.

[0143] It should be noted that, in the embodiments of this application, supporting the first QoS parameter can be understood or replaced as supporting the requirements of the QoS profile corresponding to the first speech codec. The first QoS profile includes the first QoS parameter. Similarly, supporting the second QoS parameter can be understood or replaced as supporting the requirements of the QoS profile corresponding to the second speech codec. The second QoS profile includes the second QoS parameter.

[0144] Optionally, in some embodiments, when the user equipment establishes a second voice bearer, it can receive second information from a second network-side entity. At this time, voice coding can be switched, thereby determining the first Quality of Service (QoS) parameter corresponding to the first voice coding based on the second information. This allows the second voice bearer to be modified or the first voice bearer to be re-established based on the first QoS parameter. It should be understood that before modifying the second voice bearer or re-establishing the first voice bearer based on the first QoS parameter, the user equipment communicates with the fifth network entity based on the first voice coding; after modifying the second voice bearer or re-establishing the second voice bearer based on the first QoS parameter, the user equipment can communicate with the fifth network entity based on the second voice coding.

[0145] It should be noted that the voice bearer (e.g., the first voice bearer or the second voice bearer) in the embodiments of this application can be an Evolved Packet System (EPS) bearer, or a QoS flow, or a DRB corresponding to the EPS bearer, or a DRB corresponding to the QoS flow.

[0146] In this embodiment, a first operation is performed by a first network entity. The first operation includes any one of the following: when a user equipment establishes a first voice bearer, sending first information to a second network entity; when a user equipment establishes a second voice bearer, receiving second information from a second network entity, and determining a first Quality of Service (QoS) parameter corresponding to the first voice codec based on the second information; wherein the first voice bearer supports the first QoS parameter corresponding to the first voice codec and the second QoS parameter corresponding to the second voice codec; the first information indicates at least one of the following: the network can meet the first QoS parameter; the network can meet a certain transmission rate; switching to the first voice codec; switching voice codecs; wherein the second voice bearer supports the second QoS parameter corresponding to the second voice codec; the second information indicates at least one of the following: switching voice codecs; switching to the first voice codec; switching voice codec parameters; switching to the first QoS parameter. In this way, voice codec switching can be implemented based on the first and second information to adapt to changes in different network environments and improve the quality of voice calls.

[0147] Optionally, in some embodiments, the method further includes:

[0148] The first network entity receives the first QoS parameter from the third network entity.

[0149] In this embodiment of the application, the aforementioned third network entity can be an SMF.

[0150] Optionally, if the base station determines that the requirements of the QoS profile corresponding to the second voice codec cannot be met, it can send the identifier of the voice bearer corresponding to the voice and N2 SM information to the AMF, wherein the N2 SM information contains the QoS profile corresponding to the first voice codec. The AMF can send the N2 SM information to a third network entity. The third network entity can notify the first network entity based on the N2 SM information of at least one of the following: the first QoS parameters can be met; the transmission rate can be met; switching to the first voice codec; switching voice codecs.

[0151] Optionally, in some embodiments, the method further includes:

[0152] Upon determining that the first voice bearer has been established, the first network entity sends third information to the fourth network entity, the third information including the second QoS parameter corresponding to the second voice code and the first QoS parameter.

[0153] In this embodiment of the application, the fourth network entity can be a base station.

[0154] Optionally, the first network entity may send third information directly or indirectly to the fourth network entity. For example, the first network entity may send an Npcf_SMPolicyControl_UpdateNotify message to the third network entity, carrying the second QoS parameters of the second voice codec through QoS data (QoSData), and carrying the first QoS parameters corresponding to the first voice codec through the parameter identifier (e.g., altQosParamId) of the QoS notification control information (e.g., QoSNotificationControlInfo); the third network entity, based on the information provided by the first network entity, sends a Namf_Communication_N1N2MessageTransfer message to the AMF, carrying the first QoS parameters corresponding to the first voice codec in the Alternative QoS Profile parameter of the N2 SM information, and carrying the PDU Session Modification Command to be sent to the UE in the N1 SM container; the AMF sends an N2 message to the fourth network entity, carrying the N2 SM information and the N1 SM container; the fourth network entity may save the N2 SM information and configure the user equipment according to the N2 SM information; the base station sends the N1 SM container to the user equipment.

[0155] Optionally, in some embodiments, the method further includes:

[0156] The first network entity obtains Session Description Protocol (SDP) information, which is used to determine the establishment of the first voice bearer.

[0157] In this embodiment of the application, after the second network entity completes the SDP negotiation, it sends the negotiated SDP information to the first network entity. The first network entity can determine whether to establish a first voice bearer or a second voice bearer based on the SDP information.

[0158] Optionally, in some embodiments, the method further includes:

[0159] The first network entity sends the first QoS parameter to the third network entity.

[0160] In this embodiment, the third network entity can create a new first voice bearer based on the first target parameter. Alternatively, it can modify the first voice bearer so that the modified voice bearer can support the first QoS parameters corresponding to the first voice codec. This allows the user equipment to perform voice communication on the newly created or modified voice bearer based on the first voice codec.

[0161] Optionally, in some embodiments, the encoding rate of the first speech code is lower than the encoding rate of the second speech code.

[0162] In this embodiment, switching from the second voice codec to the first voice codec can be understood as switching from high-speed voice to low-speed voice. For example, during communication, when network quality degrades, switching from high-speed voice to low-speed voice can ensure the smoothness of voice calls and avoid voice interruptions.

[0163] Of course, in other embodiments, the encoding rate of the first speech code can be higher than that of the second speech code. That is, switching from the second speech code to the first speech code can be understood as switching from low-rate speech to high-rate speech. For example, during communication, when the network quality improves, it is possible to switch from low-rate speech to high-rate speech, thereby improving the audio quality of the voice call and thus enhancing the voice call experience.

[0164] Optionally, embodiments of this application also provide a voice bearer processing method, as shown in FIG5, the voice bearer processing method including:

[0165] Step 501, the second network entity performs a second operation, the second operation including any of the following:

[0166] When the user equipment establishes the first voice bearer, it sends the first message to the fifth network entity based on the first information received from the first network entity.

[0167] When the user equipment establishes a second voice bearer, the second information is sent to the first network entity.

[0168] Wherein, the first voice bearer supports a first QoS parameter corresponding to the first voice codec and a second QoS parameter corresponding to the second voice codec. The first message is used to notify the activation of the first voice codec. The first information is used to indicate at least one of the following: the network can meet the first QoS parameter; the network can meet the transmission rate; switch to the first voice codec; switch voice codec.

[0169] Wherein, the second voice bearer supports the second QoS parameter corresponding to the second voice codec, and the second information is used to indicate at least one of the following: switching voice codecs; switching to the first voice codec; switching the parameters of the voice codec; switching to the first QoS parameter corresponding to the first voice codec.

[0170] Optionally, if a second voice bearer is established on the user equipment, the method further includes any of the following:

[0171] The second network entity receives fourth information from the user equipment, the fourth information indicating at least one of the following: switching the voice coding type; switching to the first voice coding; the bit rate that the user equipment can satisfy;

[0172] The second network entity receives fifth information from the fifth network entity, the fifth information being used to indicate at least one of the following: switching the voice coding type; switching to the first voice coding.

[0173] In this embodiment of the application, the fifth network entity mentioned above can be AGW.

[0174] Optionally, the fourth information is included in a SIP re-invitation, a SIP update message, a SIP message, or a SIP INFO message.

[0175] Optionally, the encoding rate of the first speech code is lower than the encoding rate of the second speech code.

[0176] Optionally, the coding rate of the first speech code is higher than the coding rate of the second speech code.

[0177] Optionally, embodiments of this application also provide a voice bearer processing method, as shown in FIG6, the voice bearer processing method including:

[0178] Step 601, the fifth network entity performs the third operation;

[0179] The third operation includes at least one of the following:

[0180] When the user equipment establishes the first voice bearer, it receives the first message from the first network entity and initiates the first voice encoding according to the first message.

[0181] When the user equipment establishes a second voice bearer and the received data packet carries information encoded in the first voice, the fifth information is sent to the second network entity.

[0182] The first voice bearer supports the first QoS parameter corresponding to the first voice code and the second QoS parameter corresponding to the second voice code, and the first message is used to notify the start of the first voice code.

[0183] Wherein, the second voice bearer supports the second QoS parameter corresponding to the second voice codec, and the fifth information is used to indicate at least one of the following: switching the voice codec type; switching to the first voice codec.

[0184] Optionally, the encoding rate of the first speech code is lower than the encoding rate of the second speech code.

[0185] It should be noted that, in this embodiment of the application, when the user equipment establishes a second voice bearer and the received data packet carries information of the first voice encoding, the fifth network entity can switch the voice encoding to the first voice encoding and then communicate with the user equipment based on the first voice encoding.

[0186] Optionally, embodiments of this application also provide a voice bearer processing method, as shown in FIG6, the voice bearer processing method including:

[0187] Step 701: When the user equipment establishes a second voice bearer and determines to switch from the second voice coding to the first voice coding, the user equipment sends fourth information to the second network entity.

[0188] Wherein, the second voice bearer supports the second quality of service (QoS) parameter corresponding to the second voice codec, and the fourth information is used to indicate at least one of the following: switching voice codecs; switching to the first voice codec; and the bit rate that the user equipment can satisfy.

[0189] In this embodiment, the method by which the user equipment determines whether to perform voice code switching (i.e., switching from the second voice code to the first voice code) can be set according to actual needs. For example, in some embodiments, the need to perform voice code switching can be determined based on the indication of the network-side device, and in some embodiments, the user equipment can determine whether to perform voice code switching based on the results of local statistics.

[0190] Optionally, in some embodiments, the method further includes:

[0191] The user equipment determines whether to switch from the second voice coding to the first voice coding based on the obtained transmission bit rate.

[0192] In this embodiment, the aforementioned transmission bit rate can be obtained locally by the user equipment or indicated by the network-side device. For example, in some embodiments, during voice communication based on the second voice codec by the user equipment, the network-side device or the user equipment determines the transmission bit rate. When the determined transmission bit rate meets a preset rule within a certain time, the system can switch to the first voice codec. The preset rule includes, but is not limited to, at least one of the following:

[0193] When the encoding rate of the first speech code is lower than the encoding rate of the second speech code, and the transmission bit rate is greater than the preset bit rate within a preset time period, the speech code is switched.

[0194] When the encoding rate of the first speech code is lower than the encoding rate of the second speech code, and the duration for which the transmission bit rate is greater than the preset bit rate within a preset time period is greater than the preset duration, the speech code is switched.

[0195] When the encoding rate of the first speech code is higher than the encoding rate of the second speech code, and the transmission bit rate is lower than the preset bit rate within a preset time period, the speech code is switched.

[0196] When the encoding rate of the first speech code is higher than the encoding rate of the second speech code, and the duration during which the transmission bit rate is lower than the preset bit rate is greater than the preset duration within a preset time period, the speech code is switched.

[0197] Optionally, in some embodiments, the method further includes:

[0198] The user equipment receives a fifth indication information from a third network entity, the fifth indication information being used to indicate the transmission bit rate.

[0199] Optionally, the fourth information is included in a SIP re-invitation, a SIP update message, a SIP message message (MESSAGE), or a SIP message (INFO).

[0200] Optionally, the method further includes:

[0201] The user equipment sends the data corresponding to the first voice code to the fifth network device.

[0202] In this embodiment of the application, after a period of time following the user equipment sending the fourth information to the second network entity, the user equipment may send the data corresponding to the first voice code to the fifth network device. For example, after the user equipment receives a new radio resource configuration, the user equipment may send the data corresponding to the first voice code to the fifth network device. This new radio resource configuration is used to establish a first voice bearer or modify a second voice bearer.

[0203] Optionally, to better understand this application, the following embodiments use 5G as an example for illustration. The solution of this application can also be extended to fourth-generation mobile communication technology (4G), sixth-generation mobile communication technology (6G), and seventh-generation mobile communication technology (7G), etc. For example, when extended to 4G, EPS bearer can be used instead of QoS flow, and public data network (PDN) connection can be used instead of PDU session.

[0204] In some embodiments, as shown in Figure 8, the QoS flow establishment process includes:

[0205] Step 801: After the SDP negotiation is completed, the P-CSCF sends the negotiated SDP information to the PCF.

[0206] Step 802: Based on the SDP information, the PCF determines the QoS flow that supports the QoS parameters corresponding to the two voice coding methods.

[0207] Step 803: The PCF sends a control policy update message (such as the Npcf_SMPolicyControl_UpdateNotify message) to the SMF, carrying the second QoS parameter corresponding to the second speech code (i.e., normal speech code) through QosData, and carrying the first QoS parameter corresponding to the first speech code (i.e., low-rate speech code) through the altQosParamId of QosNotificationControlInfo.

[0208] Step 804: Based on the information provided by the PCF, the SMF determines the new QoS flow that meets the QoS requirements. The SMF sends an N1N2 message transmission (e.g., Namf_Communication_N1N2MessageTransfer) message to the AMF. In this message, the Alternative QoS Profile parameter of the N2 SM information carries the first QoS parameter corresponding to the first voice codec (e.g., low-rate voice codec), and the N1 SM container carries the PDU session modification command to be sent to the first user equipment.

[0209] Step 805: AMF sends an N2 message to the base station, carrying N2 SM information and N1 SM container.

[0210] Step 806: The base station saves the N2 SM information and configures the first user equipment according to the N2 SM information;

[0211] The base station sends the N1 SM container to the first user equipment.

[0212] Step 807: Send a response message. The sending of the response message can be referred to relevant technologies, and will not be elaborated here.

[0213] Optionally, as shown in Figure 9, the process to be executed when the speech code changes includes:

[0214] Step 901: The first user equipment communicates with the second user equipment using RTP-1, and the AGW performs transparent forwarding.

[0215] Step 902: The base station determines that it cannot meet the requirements of the current QoS profile, but can meet the QoS profile of the first voice coding (such as the QoS profile of narrowband voice (alternative QoS profile)).

[0216] The current QoS profile corresponds to the QoS profile of the second speech codec (e.g., a regular speech codec).

[0217] The alternative QoS profile corresponds to the QoS profile of the first speech codec (e.g., a low-bitrate speech codec).

[0218] Step 903: The base station sends the PDU session ID and N2 SM information corresponding to the voice to the AMF. The N2 SM information includes the QoS profile corresponding to the first voice encoding.

[0219] Step 904: AMF sends N2 SM information to SMF.

[0220] Step 905: SMF sends a second message to PCF to notify PCF that the first QoS parameter can be met.

[0221] Step 906: PCF sends the first message to P-CSCF;

[0222] Step 907: P-CSCF sends a first message to AGW to notify the initiation of the first voice encoding.

[0223] Optionally, in some embodiments, as shown in FIG10, the user equipment triggering the voice code switching process via IMS signaling includes:

[0224] Step 1001: The first user equipment communicates with the second user equipment using RTP-1 (the RTP corresponding to the second voice code), and the AGW performs transparent forwarding.

[0225] Step 1002: The base station determines that the current transmission bit rate cannot be met and determines a transmission bit rate that can be met.

[0226] Step 1003, optionally, the base station sends a recommended transmission bit rate (i.e., a satisfactory bit rate) to the first user equipment through the Media Access Control (MAC) control element (CE).

[0227] Step 1004: The first user equipment determines the voice coding to switch based on the MAC CE or local statistical results, such as switching from the second voice coding to the first voice coding.

[0228] Step 1005, the first user equipment sends fourth information to the P-CSCF, the fourth information being used to indicate at least one of the following: switching the voice coding type; switching to the first voice coding; and the bit rate that the user equipment can satisfy.

[0229] Step 1006: The P-CSCF sends second information to the PCF based on the fourth information. The second information is used to indicate at least one of the following: switching voice coding; switching to the first voice coding; switching the parameters of the voice coding; switching to the first QoS parameters corresponding to the first voice coding.

[0230] It should be noted that the first user equipment can switch from the second voice codec to the first voice codec, or from the first voice codec to the second voice codec. The switching method is similar and will not be described in detail here.

[0231] Step 1007: PCF determines the first QoS parameter corresponding to the first voice code based on the second information and sends it to SMF.

[0232] Step 1008: The SMF creates a new QoS flow (i.e., the QoS flow corresponding to the first speech codec) based on the first QoS parameter, or modifies an existing QoS flow (i.e., the QoS flow corresponding to the second speech codec). Subsequent procedures can be found in relevant technologies and will not be elaborated here.

[0233] In this embodiment, the user equipment can initiate the switching of voice coding, giving the user equipment more autonomy, and the network-side equipment can guarantee the quality of the call based on the user equipment's request.

[0234] Optionally, in some embodiments, as shown in FIG11, the user equipment triggering the voice code switching process via IMS signaling includes:

[0235] Step 1101: The first user equipment communicates with the second user equipment using RTP-1 (the RTP corresponding to the second voice code), and the AGW performs transparent forwarding.

[0236] Step 1102: The base station determines the acceptable transmission bit rate.

[0237] In step 1103, optionally, the base station sends a recommended transmission bit rate to the first user equipment via a Media Access Control (MAC) control element (CE).

[0238] Step 1104: The first user equipment determines the voice coding to switch based on the MAC CE or local statistical results, such as switching from the second voice coding to the first voice coding.

[0239] Step 1105: The user equipment sends the RTP packet corresponding to the first voice code (i.e., the data corresponding to the first voice code);

[0240] Step 1106: AGW switches to the first voice encoding and sends a fifth message to P-CSCF, the fifth message indicating at least one of the following: switching the voice encoding type; switching to the first voice encoding.

[0241] Step 1107: The P-CSCF sends second information to the PCF based on the fifth information. The second information is used to indicate at least one of the following: switching voice coding; switching to the first voice coding; switching voice coding parameters; switching to the first QoS parameters corresponding to the first voice coding.

[0242] Step 1108: PCF determines the first QoS parameter corresponding to the first voice code based on the second information and sends it to SMF.

[0243] Step 1109: The SMF creates a new QoS flow (i.e., the QoS flow corresponding to the first speech codec) based on the first QoS parameter, or modifies an existing QoS flow (i.e., the QoS flow corresponding to the second speech codec). Subsequent procedures can be found in relevant technologies and will not be elaborated here.

[0244] It should be noted that the first user equipment can switch from the second voice codec to the first voice codec, or from the first voice codec to the second voice codec. The switching method is similar and will not be described in detail here.

[0245] It should be understood that in some embodiments, IMS AS can be used instead of P-CSCF to perform back-to-back user agent (B2BUA) functions, and Multimedia Resource Function Controller (MRFC) can be used instead of AGW.
