[0084] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0085] NTN provides two typical satellite access modes: transparent mode and regenerative mode according to the satellite's onboard payload capacity.

[0086] See also Figure 1 The network architecture diagram for different satellite access modes is shown. In regenerative mode, the first interface of the base station or the second interface between the base station and the core network is located on the wireless air interface between the satellite and the ground station. In this mode, the satellite not only performs RF amplification but also has processing capabilities such as modulation / demodulation, encoding / decoding, switching, and routing. In transparent mode, the UE accesses the core network via the satellite and ground station based on the 5G NR (New Radio) wireless interface. In this mode, the satellite does not process signals or waveforms during communication services and only acts as an RF amplifier to forward data.

[0087] like Figure 1 As shown, the delay in regenerative mode includes air interface delay A1 and core network delay A2. The air interface delay, also known as the AN PDB (Access Network Packet Delay Budget), corresponds to the delay between the satellite and the terrestrial UE, while the core network delay, also known as the CN PDB (Core Network PDB), corresponds to the delay between the satellite and the terrestrial core network. The delay in transparent mode includes air interface delay B1 and core network delay B2. The air interface delay corresponds to the delay between the ground base station satellite and the terrestrial UE via the satellite, and this delay is longer than the air interface delay A1. The core network delay corresponds to the delay between the ground base station and the core network, and this delay is shorter than the core network delay A2.

[0088] Since the QoS control technology for satellite access specified by the 3GPP specification is only adapted to access in transparent mode, and the air interface delay and core network delay corresponding to the regeneration mode are different from those in the transparent mode, the existing QoS control technology can no longer adapt to the situation of regeneration mode access. Therefore, it is necessary to provide a QoS control method that can adapt to regeneration mode access in order to improve the service quality of UEs accessing in regeneration mode.

[0089] To facilitate understanding, before introducing the embodiments of the present application, some relevant functional network elements involved in the present application are first introduced.

[0090] UE (User Equipment) accesses the data network (DN) and other services provided by the operator or third parties on the DN by connecting to the operator's network. For ease of explanation, in the embodiments of this application, user terminals, user equipment, terminal devices, or terminals may be collectively referred to as UEs. That is, unless otherwise specified, the UE described in the embodiments of this application can be replaced with user terminals, user equipment, terminal devices, or terminals, and of course, they are also interchangeable.

[0091] The Access and Mobility Management Function (AMF) is a control plane function in 3GPP networks, primarily responsible for access control and mobility management for UEs accessing operator networks. The Security Anchor Function (SEAF) can be deployed within the AMF, or it can be deployed in a separate device. For example, the SEAF is deployed within the AMF. When the SEAF is deployed within the AMF, the two components are collectively referred to as the AMF.

[0092] The Session Management Function (SMF) network element is a control plane function in 3GPP networks. The SMF primarily manages UE (User Data Unit) (PDU) sessions. A PDU session is a channel for transmitting PDUs. The UE can exchange PDUs with the DN through a PDU session. The SMF is responsible for establishing, maintaining, and deleting PDU sessions.

[0093] The Policy Control Function (PCF) is a control plane function in 3GPP networks that provides PDU session policies to the SMF. These policies may include billing, Quality of Service (QoS), and authorization-related policies.

[0094] A 3GPP network is a network that complies with 3GPP standards. Furthermore, a 3GPP network is not limited to the 5G network defined by 3GPP but can also include at least one of 2G, 3G, and 4G networks. 3GPP networks are typically operated by operators.

[0095] The following describes the implementation of the present application in detail with reference to the accompanying drawings and examples.

[0096] In one embodiment, Figure 2 As shown, a QoS control method is provided, which is described by taking the method applied to PCF as an example, including the following steps:

[0097] S210. Determine a first QoS parameter of the UE in the regeneration mode according to satellite access information accessed by the UE in the regeneration mode; wherein, in the regeneration mode, the base station is deployed on the satellite.

[0098] The satellite access information is used to represent the relevant information of the satellite with the base station deployed and accessed by the UE, and may include but is not limited to the access type and satellite identifier. The access type can be divided based on the satellite's orbit, for example, it can be a low-orbit satellite or a high-orbit satellite. The satellite identifier can be used as a unique identifier to distinguish different satellites. It is worth noting that the satellite access information under different access modes can be the same or different, and this application does not impose any restrictions on this.

[0099] In an optional embodiment, the satellite access information may be provided directly by the UE, or provided by other network elements in the core network, and this application does not impose any limitation on this.

[0100] QoS parameters are used to characterize technical parameters used to address issues such as network latency and congestion, and may include, for example, 5QI. The 5QI may be a value dynamically assigned by the core network or a value not assigned to it by the core network. The QoS attribute parameters corresponding to different values may be the same or at least partially different. It should be noted that the QoS parameters corresponding to different access modes are typically at least partially different. The first QoS parameter may be understood as the QoS parameter corresponding to the UE in regeneration mode.

[0101] In an optional embodiment, the QoS attribute parameters may include at least one of GBR (Guaranteed Bit Rate), Non-GBR (Non Guaranteed Bit Rate), MBR (Max Bit Rate), QCI (QoS Class Identifier), ARP (Allocation and Retention Priority) and DC GBR (Delay Critical GBR), which can be set or adjusted according to actual needs. This application does not impose any restrictions on this.

[0102] In an optional embodiment, a first correspondence between different satellite access information and QoS parameters in the regeneration mode can be pre-set; accordingly, when the UE accesses the core network through the regeneration mode, based on the above-mentioned first correspondence, the corresponding QoS parameters are searched according to the satellite access information accessed by the UE through the regeneration mode, and the search result is used as the first QoS parameter.

[0103] In another optional embodiment, a second correspondence between different satellite access information and QoS parameters under different access modes can be pre-set; accordingly, when the UE accesses the core network through the regeneration mode, based on the above second correspondence, the corresponding QoS parameters are searched according to the satellite access information accessed by the UE through the regeneration mode and the mode identifier of the regeneration mode, and the search result is used as the first QoS parameter.

[0104] It should be noted that other methods may also be used to determine the first QoS parameter, and this application does not impose any limitation on this.

[0105] Exemplarily, when the UE accesses the core network through the regeneration mode, satellite access information is provided; the PCF network element determines the first QoS parameter of the UE in the regeneration mode based on the satellite access information sent by the UE or other network elements of the core network.

[0106] S220. Send a first QoS parameter to the SMF network element so that the SMF network element sends a second QoS parameter corresponding to the first QoS parameter to the base station; wherein the second QoS parameter is used by the base station to allocate session resources to the UE.

[0107] The second QoS parameter may be used as reference data for allocating session resources to the UE. The second QoS parameter may be the same as or at least partially different from the first QoS parameter, and this application does not impose any limitation on this.

[0108] In an optional embodiment, after the PCF network element sends the first QoS parameter to the SMF network element, the SMF network element may directly use the first QoS parameter as the second QoS parameter.

[0109] In another optional embodiment, after the PCF network element sends the first QoS parameter to the SMF network element, the SMF network element may process the first QoS parameter to obtain a second QoS parameter. The processing of the first QoS parameter may be implemented using at least one conventional technology, and this application does not impose any limitation thereto.

[0110] Optionally, the SMF network element can encode the first QoS parameter to obtain a second QoS parameter that can adapt to the base station encoding method.

[0111] Alternatively, the SMF network element may add (e.g., concatenate) other parameters based on the first QoS parameter to obtain a second QoS parameter, thereby increasing the richness of the information carried by the second QoS parameter and providing rich data support for the session resource allocation process of the base station. The added other parameters may be determined based on satellite access information or based on other information during the UE access process, and this application does not impose any limitation on this.

[0112] In one specific implementation, the other parameter may be core network latency information determined based on the access type in the satellite access information. The core network latency information is used to characterize the latency of core network data transmission during network communication, such as a time length or a latency level.

[0113] In an optional implementation, both the second QoS parameter and the first QoS parameter include 5QI, thereby avoiding the loss of key information in the first QoS parameter in the second QoS parameter, laying the foundation for the reasonable allocation of subsequent UE session resources, and thus providing a guarantee for improving the subsequent communication service quality.

[0114] In another optional embodiment, the 5QI included in the first QoS parameter and the second QoS parameter is different from the 5QI when the UE accesses the network in transparent mode, where the base station is deployed on the ground. This has the advantage of distinguishing the 5QIs of different access modes, avoiding mixing of 5QIs of different access modes and causing unreasonable allocation of session resources to the UE, thereby helping to improve communication quality in different access modes.

[0115] Exemplarily, the 5QI included in the first QoS parameter and the second QoS parameter may be at least partially different from the 5QI when the UE accesses through transparent mode, that is, the two may be partially different or completely different, and this application does not impose any limitations on this.

[0116] In a specific implementation, the 5QI included in the first QoS parameter and the second QoS parameter is different from the 5QI value corresponding to the transparent mode. For example, the first QoS parameter may be 10, and the second QoS parameter may be 15.

[0117] In another specific implementation, the 5QI contained in the first QoS parameter and the second QoS parameter includes the 5QI corresponding to the transparent mode and indication information of the regeneration mode, so that the 5QI corresponding to different access modes can be distinguished through the indication information of the regeneration mode.

[0118] Among them, the indication information can be implemented in the form of an identifier, and this application does not impose any limitation on the specific presentation method of the indication information.

[0119] Optionally, corresponding indication information may be set only for the regeneration mode, and no corresponding indication information may be allocated for the transparent mode. The 5QIs in different access modes may be distinguished by the presence or absence of the indication information.

[0120] Alternatively, different indication information may be allocated to different access modes, that is, first indication information may be allocated to the regeneration mode, and second indication information different from the first indication information may be allocated to the transparent mode. Different access modes may be distinguished by the two indication information.

[0121] In the embodiment of the present application, by introducing satellite access information of the UE in regeneration mode, the PCF network element determines the first QoS parameter of the UE in regeneration mode based on the satellite access information, and sends the first QoS parameter to the SMF network element. The SMF network element then sends a second QoS parameter corresponding to the first QoS parameter to the base station for the base station to allocate session resources to the UE. The above method provides a new QoS control mechanism applicable to regeneration mode, avoids the QoS control mechanism in the multiplexing transparent mode, and avoids the poor service quality caused by the different delays of different access modes. It improves the rationality of the session resource allocation results for UEs accessing in regeneration mode, thereby improving the service quality of UEs in the case of regeneration mode access.

[0122] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment in which the process of acquiring satellite access information is refined.

[0123] join Figure 3 The steps for obtaining satellite access information shown include:

[0124] S310. Receive a session management policy processing request sent by the SMF network element.

[0125] The session management policy processing request indicates that the UE currently has session management requirements and is used to instruct the PCF network element to process the session management policy.

[0126] Exemplarily, when the UE accesses through the regeneration mode, the SMF network element generates a session management policy processing request; the SMF network element sends the session management policy processing request to the PCF network element; the PCF network element receives and responds to the session management policy processing request sent by the SMF network element.

[0127] In an optional embodiment, the session management policy processing request may include a session management policy creation request; accordingly, the SMF network element generates the session management policy creation request when the UE accesses through the regeneration mode; the PCF network element receives the session management policy creation request and creates a session management policy in response to the session management policy creation request.

[0128] In another optional embodiment, the session management policy processing request may include a session management policy update request; accordingly, the SMF network element generates the session management policy update request when the UE accesses the network in regeneration mode; the PCF network element receives the session management policy update request and, in response to the session management policy update request, updates the previously established session management policy. The session management policy update request may include at least one of a modification request for instructing modification of the session management policy, a change request for instructing change of the session management policy, and a deletion request for instructing deletion of the session management policy.

[0129] S320: Obtain satellite access information accessed by the UE in regeneration mode from the session management policy processing request.

[0130] In an optional embodiment, the session management policy processing request may carry satellite access information accessed by the UE in the regeneration mode; accordingly, the PCF network element may obtain the satellite access information by parsing the session management policy processing request.

[0131] In another optional embodiment, the session management policy processing request may carry access association information of the satellite access information accessed by the UE through the regeneration mode; accordingly, the PCF network element may determine the satellite access information accessed by the UE through the regeneration mode through the access association information and in combination with the pre-set association relationship between different access association information and satellite access information.

[0132] The embodiment of the present application reduces the number of communications between the SMF network element and the PCF network element by merging the transmission process of satellite access information and the transmission process of session management policy processing requests into the same process, thereby reducing unnecessary communication waiting time and improving communication efficiency.

[0133] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment. In this optional embodiment, the process of determining the first QoS parameter in S210 is refined.

[0134] See also Figure 4 The steps of determining the first QoS parameter shown include:

[0135] S410. Determine a PCC policy for a PDU session of the UE according to satellite access information accessed by the UE in the regeneration mode; wherein the PCC policy includes a first QoS parameter of the UE in the regeneration mode.

[0136] The PCC policy involves the management and control of at least one of data transmission, access, and billing in the communication network. It aims to provide users with more flexible data services and perform traffic management and billing control based on different user needs and network conditions, thereby ensuring network stability and security.

[0137] PCC policies can provide policy control and charging control functions. Policy management can include at least one of flow control, priority management, and access control to ensure efficient utilization of network resources and improved service quality. Charging control can manage and control user data usage and implement charging management based on different charging policies, such as those based on at least one factor, such as flow, time, and service quality.

[0138] The PCC policy includes the first QoS parameter of the UE in the regeneration mode, thereby improving the richness of the information carried in the PCC policy.

[0139] In an optional embodiment, a first policy correspondence relationship between different satellite access information and the PCC policy of the PDU session can be established in advance; accordingly, when the UE accesses the core network through the regeneration mode, based on the above-mentioned first policy correspondence relationship, a PCC policy matching the satellite access information of this access is searched.

[0140] In another optional embodiment, a second policy correspondence may be established between different satellite access information and PCC policies for PDU sessions in different access modes. Accordingly, when the UE accesses the core network in regeneration mode, a PCC policy matching the satellite access information for the current access in the regeneration mode is searched based on the second policy correspondence. The QoS parameters carried in the PCC policies for the same satellite access information in different access modes may differ at least in part.

[0141] It is worth noting that the PCC policy determination process may also be implemented in other ways, and this application does not impose any limitation on this.

[0142] Optionally, the PCF network element may obtain satellite access information from the UE or other network elements of the core network and directly determine the PCC policy of the PDU session according to the satellite access information.

[0143] To avoid repeated determination of the PCC policy or redundant determination of an invalid access process, the PCC policy for the UE's PDU session can optionally be determined in response to a session management policy processing request sent by the SMF network element based on the satellite access information accessed by the UE in regeneration mode. Accordingly, the PCF sends a session management policy processing response corresponding to the session management policy processing request to the SMF network element; wherein the session management policy processing response carries the PCC policy.

[0144] The above method of carrying the PCC policy in the session management policy processing response can determine the PCC policy on demand, avoid repeated determination of the PCC policy or redundant determination in the case of invalid access, reduce unnecessary data calculations in the PCF network element, and thus save computing resources of the PCF network element.

[0145] Unlike the traditional PCC policy, the PCC policy of the present application carries the first QoS parameter corresponding to the regeneration mode, so that the determination process of the first QoS parameter can be combined with the determination process of the PCC policy, thereby reducing unnecessary transmission waiting time during the communication process, reducing data processing logic, thereby reducing data calculation volume, and further improving communication efficiency.

[0146] The technical solutions of the above embodiments are based on PCF network elements as the execution body, and the QoS control method is described in detail. The following will be based on SMF network elements as the execution body to describe the QoS control method in detail. It should be noted that for parts not described in detail in the embodiments of this application, please refer to the relevant descriptions of other embodiments.

[0147] See also Figure 5 The QoS control method shown includes:

[0148] S510. Receive a first QoS parameter sent by a PCF network element; wherein the first QoS parameter is determined by the PCF network element according to satellite access information accessed by the UE in a regeneration mode, where the base station is deployed on a satellite in the regeneration mode.

[0149] QoS parameters are used to characterize technical parameters used to address issues such as network latency and congestion, and may include, for example, 5QI. The 5QI may be a value dynamically assigned by the core network or a value not assigned to it by the core network. The QoS attribute parameters corresponding to different values may be the same or at least partially different. It should be noted that the QoS parameters corresponding to different access modes are typically at least partially different. The first QoS parameter may be understood as the QoS parameter corresponding to the UE in regeneration mode.

[0150] In an optional embodiment, the QoS attribute parameters may include at least one of GBR (Guaranteed Bit Rate), Non-GBR (Non Guaranteed Bit Rate), MBR (Max Bit Rate), QCI (QoS Class Identifier), ARP (Allocation and Retention Priority) and DC GBR (Delay Critical GBR), which can be set or adjusted according to actual needs. This application does not impose any restrictions on this.

[0151] Exemplarily, the PCF network element determines a first QoS parameter based on satellite access information accessed by the UE through the regeneration mode, and sends the first QoS parameter to the SMF network element; the SMF network element receives the first QoS parameter for subsequent use.

[0152] S520. Send a second QoS parameter corresponding to the first QoS parameter to the base station; wherein the second QoS parameter is used by the base station to allocate session resources to the UE.

[0153] The second QoS parameter may be used as reference data for allocating session resources to the UE. The second QoS parameter may be the same as or at least partially different from the first QoS parameter, and this application does not impose any limitation on this.

[0154] In an optional embodiment, the first QoS parameter may be directly used as the second QoS parameter.

[0155] In another optional embodiment, the first QoS parameter may be processed to obtain the second QoS parameter. The processing of the first QoS parameter may be implemented using at least one conventional technology, which is not limited in this application.

[0156] Optionally, the first QoS parameter may be coded to obtain a second QoS parameter that can adapt to a coding mode of the base station.

[0157] Alternatively, other parameters may be added (e.g., concatenated) to the first QoS parameters to obtain second QoS parameters, thereby increasing the richness of information carried by the second QoS parameters and providing richer data support for the base station's session resource allocation process. The added other parameters may be determined based on satellite access information or other information during the UE access process, and this application does not impose any limitations on this.

[0158] Exemplarily, the SMF can determine the core network delay information of the UE in the regeneration mode based on the access type in the satellite access information that the UE accesses through the regeneration mode, and add the core network delay information as other parameters to the first QoS parameter to obtain the second QoS parameter.

[0159] The core network delay information is used to characterize the delay of core network data transmission during network communication, for example, it can be the time length or delay level.

[0160] It can be understood that if the satellite access information is the satellite access information that the UE accesses through the transparent mode, the core network delay information of the UE in the transparent mode can also be determined according to the access type of the satellite access information, and the core network delay information can be added to the QoS parameters based on the transparent mode to obtain new QoS parameters adapted to the transparent mode, which are used to instruct the base station to allocate session resources to the UE, thereby applying the QoS control method in this application to the transparent mode and improving the universality of the QoS control method.

[0161] It is worth noting that by adding core network delay information to the second QoS parameter, the richness of the information carried in the second QoS parameter can be improved, providing richer data support for the process of allocating session resources to the UE, thereby improving the rationality of the session resource allocation results and further improving the service quality of the UE communication process.

[0162] In an optional implementation, both the second QoS parameter and the first QoS parameter include 5QI, thereby avoiding the loss of key information in the first QoS parameter in the second QoS parameter, laying the foundation for the reasonable allocation of subsequent UE session resources, and thus providing a guarantee for improving the subsequent communication service quality.

[0163] In another optional embodiment, the 5QI included in the first QoS parameter and the second QoS parameter is different from the 5QI when the UE accesses the network in transparent mode, where the base station is deployed on the ground. This has the advantage of distinguishing the 5QIs of different access modes, avoiding mixing of 5QIs of different access modes and causing unreasonable allocation of session resources to the UE, thereby helping to improve communication quality in different access modes.

[0164] Exemplarily, the 5QI included in the first QoS parameter and the second QoS parameter may be at least partially different from the 5QI when the UE accesses through transparent mode, that is, the two may be partially different or completely different, and this application does not impose any limitations on this.

[0165] In a specific implementation, the 5QI included in the first QoS parameter and the second QoS parameter has a different value from the 5QI corresponding to the transparent mode.

[0166] In another specific implementation, the 5QI contained in the first QoS parameter and the second QoS parameter includes the 5QI corresponding to the transparent mode and indication information of the regeneration mode, so that the 5QI corresponding to different access modes can be distinguished through the indication information of the regeneration mode.

[0167] Among them, the indication information can be implemented in the form of an identifier, and this application does not impose any limitation on the specific presentation method of the indication information.

[0168] Optionally, corresponding indication information may be set only for the regeneration mode, and no corresponding indication information may be allocated for the transparent mode. The 5QIs in different access modes may be distinguished by the presence or absence of the indication information.

[0169] Alternatively, different indication information may be allocated to different access modes, that is, first indication information may be allocated to the regeneration mode, and second indication information different from the first indication information may be allocated to the transparent mode. Different access modes may be distinguished by the two indication information.

[0170] In the embodiment of the present application, by introducing satellite access information of the UE in regeneration mode, the PCF network element determines the first QoS parameter of the UE in regeneration mode based on the satellite access information, and sends the first QoS parameter to the SMF network element. The SMF network element then sends a second QoS parameter corresponding to the first QoS parameter to the base station for the base station to allocate session resources to the UE. The above method provides a new QoS control mechanism applicable to regeneration mode, avoids the QoS control mechanism in the multiplexing transparent mode, and avoids the poor service quality caused by the different delays of different access modes. It improves the rationality of the session resource allocation results for UEs accessing in regeneration mode, thereby improving the service quality of UEs in the case of regeneration mode access.

[0171] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment. In this optional embodiment, a step before receiving the first QoS parameter in S510 is added.

[0172] See also Figure 6 The steps of determining satellite access information shown include:

[0173] S610: Send a session management policy processing request to the PCF network element; wherein the session management policy processing request carries satellite access information accessed by the UE in regeneration mode.

[0174] The session management policy processing request indicates that the UE currently has session management requirements and is used to instruct the PCF network element to process the session management policy.

[0175] Exemplarily, when the UE accesses through the regeneration mode, the SMF network element generates a session management policy processing request; the SMF network element sends the session management policy processing request to the PCF network element; accordingly, the PCF network element receives and responds to the session management policy processing request sent by the SMF network element.

[0176] In an optional embodiment, the session management policy processing request may include a session management policy creation request; accordingly, the SMF network element generates the session management policy creation request when the UE accesses through the regeneration mode; the PCF network element receives the session management policy creation request and creates a session management policy in response to the session management policy creation request.

[0177] In another optional embodiment, the session management policy processing request may include a session management policy update request; accordingly, the MF network element generates the session management policy update request when the UE accesses the network in regeneration mode; the PCF receives the session management policy update request and, in response to the session management policy update request, updates the previously established session management policy. The session management policy update request may include at least one of a policy modification request for instructing modification of the session management policy, a policy change request for instructing change of the session management policy, and a policy deletion request for instructing deletion of the session management policy.

[0178] Furthermore, since the session management policy processing request carries the satellite access information accessed by the UE in the regeneration mode, after obtaining the session management policy processing request, the PCF network element can also obtain the satellite access information carried in the session management policy processing request.

[0179] It is worth noting that the session management policy processing request can directly carry the satellite access information of the UE accessing via the regeneration mode; accordingly, the PCF network element can obtain the satellite access information by parsing the session management policy processing request. Alternatively, the session management policy processing request can carry access association information of the satellite access information of the UE accessing via the regeneration mode; accordingly, the PCF network element can determine the satellite access information of the UE accessing via the regeneration mode by using the access association information and combining it with the pre-defined association between different access association information and satellite access information.

[0180] The embodiment of the present application reduces the number of communications between the SMF network element and the PCF network element by merging the transmission process of satellite access information and the transmission process of session management policy processing requests into the same process, thereby reducing unnecessary communication waiting time and improving communication efficiency.

[0181] Based on the technical solutions of the above embodiments, the present application also provides different implementation methods for the SMF network element to receive the first QoS parameter.

[0182] In an optional embodiment, the SMF network element may directly receive the first QoS parameter sent by the PCF network element.

[0183] In another optional embodiment, the SMF network element can receive the PCC policy for the PDU session of the UE determined by the PCF network element and carry the first QoS parameter in the PCC policy, so as to merge the determination process of the first QoS parameter with the determination process of the PCC policy, thereby reducing unnecessary transmission waiting time during the communication process, reducing data processing logic, thereby reducing the amount of data calculation, and further improving communication efficiency.

[0184] In order to avoid repeated determination of the PCC policy or redundant determination of an invalid access process, optionally, the PCF network element may also respond to the session management policy processing request sent by the SMF network element, determine the PCC policy for the UE's PDU session based on the satellite access information accessed by the UE through the regeneration mode, and send a session management policy processing response to the SMF network element; accordingly, the SMF network element receives the session management policy processing response; wherein, the session management policy processing response carries the PCC policy for the UE's PDU session, and the PCC policy includes the first QoS parameter of the UE in the regeneration mode.

[0185] The above method of carrying the PCC policy in the session management policy processing response can determine the PCC policy on demand, avoiding repeated determination of the PCC policy or redundant determination in the case of invalid access, thereby reducing unnecessary data calculations in the PCF network element and saving computing resources of the PCF network element.

[0186] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment, in which the process of acquiring satellite access information is described in detail.

[0187] See also Figure 7 The steps for obtaining satellite access information shown include:

[0188] S710. Receive a session processing request sent by the AMF network element.

[0189] S720: Obtain satellite access information accessed by the UE in the regeneration mode from the session processing request.

[0190] When a UE accesses the core network, the AMF network element in the core network sends a session processing request to the SMF network element to request that session resources be allocated to the UE, thereby providing communication services to the UE based on the session resources. Accordingly, the SMF network element receives the session processing request, feeds back a session processing response to the AMF network element, and sends a session management policy processing request to the PCF network element, instructing the PCF network element to determine the PCC policy for the PDU session for the UE.

[0191] The session handling request may include a session creation request for instructing session creation and a session update request for instructing session update. The session update request may include at least one of a session modification request for instructing session modification, a session change request for instructing session alteration, and a session deletion request for instructing session deletion. Accordingly, the session management policy handling request may include at least one of a session management policy creation request corresponding to a session creation request, a session management policy modification request corresponding to a session modification request, a session management policy change request corresponding to a session alteration request, and a session management policy deletion request corresponding to a session deletion request.

[0192] Unlike traditional session processing requests, the session processing request in this application can carry satellite access information that the UE accesses through the regeneration mode; accordingly, the SMF network element can directly obtain the satellite access information carried by parsing the session processing request.

[0193] Or optionally, the session processing request can carry access association information associated with the satellite access information; accordingly, the SMF network element can determine the satellite access information accessed by the UE through the regeneration mode through the access association information and in combination with the pre-set association relationship between different access association information and satellite access information.

[0194] The embodiment of the present application determines satellite access information by processing requests based on AMF network elements, providing different feasible methods for SMF network elements to obtain satellite access information, thereby improving the diversity and reliability of satellite access information acquisition methods.

[0195] In an optional embodiment, the SMF network element may directly send the second QoS parameter corresponding to the first QoS parameter to the base station. Alternatively, the SMF network element may also send the second QoS parameter corresponding to the first QoS parameter to the base station through the AMF network element, thereby achieving network access control and mobility management for the UE.

[0196] Among them, the second QoS parameter can use at least one traditional message to realize signaling transmission between SMF network elements, AMF network elements and base stations. This application does not impose any restrictions on this.

[0197] In one specific implementation, the SMF network element may send an N1N2 message to the AMF network element; wherein the message carries a second QoS parameter corresponding to the first QoS parameter, and the N1N2 message is used to instruct the AMF network element to send a PDU session resource establishment request carrying the second QoS parameter corresponding to the first QoS parameter to the base station. Accordingly, the base station allocates session resources for the UE accessing in regeneration mode in response to the session resource establishment request.

[0198] It can be understood that by reusing the existing message transmission mechanism of the AMF network element, the convenience of message transmission between the SMF network element and the base station is improved, while the reuse of the existing network transmission mechanism is realized, and the stability of the network transmission process is improved. The technical solution of the above embodiment takes the SMF network element as the execution subject and describes the QoS control method in detail. The following will take the base station deployed on the satellite as the execution subject to describe the QoS control method in detail. It should be noted that for the parts not described in detail in the embodiments of this application, please refer to the relevant statements of other embodiments.

[0199] See also Figure 8 The QoS control method shown includes:

[0200] S810. Obtain a second QoS parameter sent by the core network; wherein the first QoS parameter corresponding to the second QoS parameter is determined by the PCF network element according to satellite access information accessed by the UE through a regeneration mode, and the base station is deployed on the satellite in the regeneration mode.

[0201] QoS parameters are used to characterize technical parameters used to address issues such as network latency and congestion, and may include, for example, 5QI. The 5QI may be a value dynamically assigned by the core network or a value not assigned to it by the core network. The QoS attribute parameters corresponding to different values may be the same or at least partially different. It should be noted that the QoS parameters corresponding to different access modes are typically at least partially different. The first QoS parameter may be understood as the QoS parameter corresponding to the UE in regeneration mode.

[0202] In an optional embodiment, the QoS attribute parameters may include at least one of GBR (Guaranteed Bit Rate), Non-GBR (Non Guaranteed Bit Rate), MBR (Max Bit Rate), QCI (QoS Class Identifier), ARP (Allocation and Retention Priority) and DC GBR (Delay Critical GBR), which can be set or adjusted according to actual needs. This application does not impose any restrictions on this.

[0203] Exemplarily, the PCF network element determines a first QoS parameter based on the satellite access information accessed by the UE through the regeneration mode, and sends the first QoS parameter to the SMF network element; the SMF network element receives the first QoS parameter and sends a second QoS parameter corresponding to the first QoS parameter to the base station.

[0204] The second QoS parameter may be used as reference data for allocating session resources to the UE. The second QoS parameter may be the same as or at least partially different from the first QoS parameter, and this application does not impose any limitation on this.

[0205] In an optional embodiment, the first QoS parameter may be directly used as the second QoS parameter.

[0206] In another optional embodiment, the first QoS parameter may be processed to obtain the second QoS parameter. The processing of the first QoS parameter may be implemented using at least one conventional technology, which is not limited in this application.

[0207] Optionally, the first QoS parameter may be coded to obtain a second QoS parameter that can adapt to a coding mode of the base station.

[0208] Alternatively, other parameters may be added (e.g., concatenated) to the first QoS parameters to obtain second QoS parameters, thereby increasing the richness of information carried by the second QoS parameters and providing richer data support for the base station's session resource allocation process. The added other parameters may be determined based on satellite access information or other information during the UE access process, and this application does not impose any limitations on this.

[0209] Exemplarily, the SMF can determine the core network delay information of the UE in the regeneration mode based on the access type in the satellite access information that the UE accesses through the regeneration mode, and add the core network delay information as other parameters to the first QoS parameter to obtain the second QoS parameter.

[0210] The core network delay information is used to characterize the delay of core network data transmission during network communication, for example, it can be the time length or delay level.

[0211] It can be understood that if the satellite access information is the satellite access information that the UE accesses through the transparent mode, the core network delay information of the UE in the transparent mode can also be determined according to the access type of the satellite access information, and the core network delay information can be added to the QoS parameters based on the transparent mode to obtain new QoS parameters adapted to the transparent mode, which are used to instruct the base station to allocate session resources to the UE, thereby applying the QoS control method in this application to the transparent mode and improving the universality of the QoS control method.

[0212] It is worth noting that by adding core network delay information to the second QoS parameter, the richness of the information carried in the second QoS parameter can be improved, providing richer data support for the process of allocating session resources to the UE, thereby improving the rationality of the session resource allocation results and further improving the service quality of the UE communication process.

[0213] In an optional implementation, both the second QoS parameter and the first QoS parameter include 5QI, thereby avoiding the loss of key information in the first QoS parameter in the second QoS parameter, laying the foundation for the reasonable allocation of subsequent UE session resources, and thus providing a guarantee for improving the subsequent communication service quality.

[0214] In another optional embodiment, the 5QI included in the first QoS parameter and the second QoS parameter is different from the 5QI when the UE accesses the network in transparent mode, where the base station is deployed on the ground. This has the advantage of distinguishing the 5QIs of different access modes, avoiding mixing of 5QIs of different access modes and causing unreasonable allocation of session resources to the UE, thereby helping to improve communication quality in different access modes.

[0215] Exemplarily, the 5QI included in the first QoS parameter and the second QoS parameter may be at least partially different from the 5QI when the UE accesses through transparent mode, that is, the two may be partially different or completely different, and this application does not impose any limitations on this.

[0216] In a specific implementation, the 5QI included in the first QoS parameter and the second QoS parameter has a different value from the 5QI corresponding to the transparent mode.

[0217] In another specific implementation, the 5QI contained in the first QoS parameter and the second QoS parameter includes the 5QI corresponding to the transparent mode and indication information of the regeneration mode, so that the 5QI corresponding to different access modes can be distinguished through the indication information of the regeneration mode.

[0218] Among them, the indication information can be implemented in the form of an identifier, and this application does not impose any limitation on the specific presentation method of the indication information.

[0219] Optionally, corresponding indication information may be set only for the regeneration mode, and no corresponding indication information may be allocated for the transparent mode. The 5QIs in different access modes may be distinguished by the presence or absence of the indication information.

[0220] Alternatively, different indication information may be allocated to different access modes, that is, first indication information may be allocated to the regeneration mode, and second indication information different from the first indication information may be allocated to the transparent mode. Different access modes may be distinguished by the two indication information.

[0221] S820: Allocate session resources to the UE according to the second QoS parameter.

[0222] In an optional embodiment, the air interface delay information can be determined based on the 5QI included in the second QoS parameter, and session resources can be allocated to the UE based on the air interface delay information, so that the impact of the air interface delay during the UE session can be reduced, thereby improving the UE session quality.

[0223] In another optional embodiment, the air interface delay information can also be determined based on the 5QI and core network delay information included in the second QoS parameter, and session resources can be allocated to the UE based on the air interface delay information. The advantage of doing this is that since the core network delay information is referenced in the process of determining the air interface delay information, the air interface delay information can cover the delay between the UE and the base station and the delay between the base station and the core network, making the air interface delay information more accurate, thereby further improving the rationality and accuracy of the session resources allocated to the UE, and thus improving the session quality of the UE. Among them, the core network delay information can be determined by the SMF network element based on the access type in the satellite access information that the UE accesses through the regeneration mode, or by other network elements based on other information. This application does not impose any restrictions on this.

[0224] In the embodiment of the present application, by introducing satellite access information of the UE in regeneration mode, the PCF network element determines the first QoS parameter of the UE in regeneration mode based on the satellite access information, and sends the first QoS parameter to the SMF network element. The SMF network element then sends a second QoS parameter corresponding to the first QoS parameter to the base station for the base station to allocate session resources to the UE. The above method provides a new QoS control mechanism applicable to regeneration mode, avoids the QoS control mechanism in the multiplexing transparent mode, and avoids the poor service quality caused by the different delays of different access modes. It improves the rationality of the session resource allocation results for UEs accessing in regeneration mode, thereby improving the service quality of UEs in the case of regeneration mode access.

[0225] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment, in which the method for obtaining the second QoS parameter is refined.

[0226] In an optional embodiment, the SMF network element may directly send the second QoS parameter corresponding to the first QoS parameter to the base station. Alternatively, the SMF network element may also send the second QoS parameter corresponding to the first QoS parameter to the base station through the AMF network element, thereby achieving network access control and mobility management for the UE.

[0227] Among them, the second QoS parameter can use at least one traditional message to realize signaling transmission between SMF network elements, AMF network elements and base stations. This application does not impose any restrictions on this.

[0228] In a specific implementation, the SMF network element can send an N1N2 message to the AMF network element; wherein the message carries a second QoS parameter corresponding to the first QoS parameter; the AMF network element sends a PDU session resource establishment request carrying the second QoS parameter to the base station; accordingly, the base station can obtain the PDU session resource establishment request sent by the AMF network element in the core network; and obtain the second QoS parameter from the PDU session resource establishment request.

[0229] It can be understood that the transmission method of the above-mentioned second QoS parameter improves the convenience of message transmission between SMF network elements and base stations by reusing the existing message transmission mechanism of AMF network elements, while realizing the reuse of existing network transmission mechanisms and improving the stability of the network transmission process.

[0230] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment, in which the QoS control process when the UE accesses the core network through the regeneration mode is introduced in detail.

[0231] See also Figure 9The QoS control method shown includes:

[0246] Based on the same inventive concept, embodiments of the present application also provide a service quality control device for implementing the aforementioned service quality control method. The solution provided by this device is similar to the solution described in the aforementioned method. Therefore, the specific limitations in one or more of the following embodiments of the service quality control device can be found in the limitations of the service quality control method above and will not be repeated here.
