The URSP information comprises indication information indicating that the terminal creates a PDU Session, service flow description information of a service needing to create a PDU Session and route description information of a route used to create a PDU Session. The present scheme can well solve the problems of poor flexibility, maintainability and implementability in the differentiated rate control of the non-GBR QoS Flow in the prior art.

Description

Technical Field

[0001] This invention relates to the field of terminal technology, and in particular to an information transmission method, apparatus, PCF entity, terminal, and business operation support system. Background Technology

[0002] QoS (Quality of Service) is a means of providing differentiated services to different users and services. The network schedules and forwards resources based on QoS parameters to achieve different latency, speed, and reliability performance. In 5G networks, the smallest granularity for achieving differentiated QoS guarantees is the QoS Flow. Depending on whether an absolute rate guarantee can be provided, QoS Flow can be divided into non-GBR (no bit rate guarantee, i.e., no minimum transmission rate guarantee) QoS Flow and GBR (guaranteed bit rate) QoS Flow. Currently, by setting parameters such as Session-AMBR (Session Aggregate Maximum Bit Rate), it is possible to implement upper limit rate control for non-GBR QoS flows under a PDU (Protocol Data Unit) session. That is, for a given PDU-Session, once Session-AMBR is set, the sum of the rates of all non-GBR QoS flows under that PDU-Session will be limited by Session-AMBR. For example, in a scenario where general traffic rate limiting does not affect the unrestricted rate of targeted services, a session may have three non-GBR QoS flows (F1, F2, F3). Initially, Session-AMBR is set to 2Gbps. When general traffic exceeds the limit (defined here as the sum of F1 and F2 traffic), according to the traffic over-limit rate limiting requirement, Session-AMBR is set to 1Gbps. Then, these three non-GBR QoS flows... The sum of the flow rates will not exceed 1Gbps, but F3, as a targeted service flow, has differentiated rate requirements (i.e., no rate limit). This method cannot achieve a rate for F3 exceeding 1Gbps. To achieve further differentiated rate control for non-GBR QoS flows, Session-AMBR will no longer be applicable, and it can only be achieved by configuring the flow-level MBR (Maximum Bit Rate) and rule priorities on a per-flow basis.

[0003] As shown above, existing solutions address the issue of differentiated rate control for non-GBR QoS flows to some extent, but their flexibility, maintainability, and implementability are very poor. This is reflected in: 1) Numerous rule configurations: Configuration needs to be performed flow-by-flow based on the rule requirements of each flow; the more rules there are, the more configuration data is required. 2) Complex PCC (Policy Control and Billing) updates and maintenance: Rule priorities must be planned in advance; if a non-GBR flow needs to change its priority, the entire PCC rule configuration list may need to be updated. In scenarios such as subscriptions and promotions of targeted services with no rate limits, this will severely impact service implementation.

[0004] In other words, existing technologies suffer from very poor flexibility, maintainability, and implementability in managing differentiated rates for non-GBR QoS Flows. Summary of the Invention

[0162] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0163] This invention addresses the shortcomings of existing technologies in differentiated rate control of non-GBR QoS Flows, which suffer from poor flexibility, maintainability, and implementability. It provides an information transmission method applicable to Packet Control Function (PCF) entities, such as... Figure 1 As shown, it includes:

[0164] Step 11: If it is confirmed that a Protocol Data Unit Session (PDU Session) needs to be created for a non-GBR QoS Flow that does not guarantee bit rate QoS, generate User Routing Policy (URSP) information;

[0165] Step 12: Transmit the URSP information to the terminal; wherein, the rate parameter information of the non-GBR QoS Flow is without rate limit; the URSP information includes: indication information instructing the terminal to create a PDU Session, service flow description information of the service for which a PDU Session needs to be created, and route description information of the route used to create the PDU Session.

[0166] Specifically, the indication information includes an indication value. If the indication value is a first value, it indicates that the terminal is instructed to create a PDU Session; if the indication value is a second value, it indicates that the terminal is instructed not to create a PDU Session; and / or,

[0167] The service flow description information includes service flow IP address information, service identification information, and / or website URL information; and / or,

[0168] The routing description information includes slice information, data network name (DNN) information, PDU session type information, time information, and / or location information.

[0169] The information transmission method provided in this embodiment of the invention generates User Routing Policy (URSP) information when it is confirmed that a Protocol Data Unit (PDU) Session needs to be created for a non-GBR QoS Flow that does not guarantee bit rate QoS. The URSP information is then transmitted to the terminal. The rate parameter information of the non-GBR QoS Flow has no rate cap. The URSP information includes: an instruction to the terminal to create a PDU Session, service flow description information of the service for which a PDU Session needs to be created, and route description information of the route used to create the PDU Session. This method enables the generation of an URSP that will definitely trigger the terminal to create a new PDU Session for a non-GBR QoS Flow with differentiated rate control requirements, and transmits this URSP to the terminal. This instructs the terminal to create a new PDU Session for the non-GBR QoS Flow with differentiated rate control requirements, and transmits the non-GBR QoS Flow on the newly created PDU Session to meet the differentiated rate control requirements of the non-GBR QoS Flow. This achieves separate control of the non-GBR QoS Flow, avoids configuring flow-level MBRs and rule priorities per flow, and thus guarantees non-GBR QoS. The flexibility, maintainability, and implementability of the differentiated rate control for flow effectively solve the problem of poor flexibility, maintainability, and implementability in existing technologies for differentiated rate control of non-GBR QoS flows.

[0170] Furthermore, before generating URSP information, the process also includes: receiving policy subscription information sent by the business operation support system; and, based on the policy subscription information, confirming whether a PDU Session needs to be created for the non-GBR QoS Flow.

[0171] The policy subscription information includes: user identification information and policy coding information.

[0172] Regarding "confirming whether a PDU Session needs to be created for non-GBR QoS Flow", the embodiments of this invention provide the following two implementation methods:

[0173] In the first method, determining whether a PDU Session needs to be created for a non-GBR QoS Flow based on the policy subscription information includes: determining whether the non-GBR QoS Flow exists based on the policy encoding information in the policy subscription information; and if it exists, confirming that a PDU Session needs to be created for the non-GBR QoS Flow.

[0174] The second method involves determining whether a PDU Session needs to be created for a non-GBR QoS Flow based on the policy subscription information. This includes: determining whether the current PDU Session meets the non-GBR QoS Flow requirements based on the service flow information of the current PDU Session and the policy coding information in the policy subscription information; if not, confirming that a PDU Session needs to be created for the non-GBR QoS Flow; if so, continuing the operation of determining whether a PDU Session needs to be created for the non-GBR QoS Flow based on the policy subscription information; wherein the service flow information includes the rate control information of the current PDU session; and the policy coding information includes the required rate information of the non-GBR QoS Flow.

[0175] The service flow information for the current PDU session is available on the PCF. Because the PCF controls the rate of service flows for all PDU sessions, it knows the service flow information for the current PDU session.

[0176] In this embodiment of the invention, generating User Routing Policy (URSP) information includes: generating URSP information based on service flow related information; wherein the service flow related information includes at least one of the following: service identifier information; application identifier information; service server IP address information; application server IP address information; URL information; and data network access identifier (DNAI) information.

[0177] The business flow-related information is carried in the policy signing information, or the business flow-related information is generated by the PCF entity.

[0178] This invention also provides an information transmission method applied to a terminal, such as... Figure 2 As shown, it includes:

[0179] Step 21: Receive User Routing Policy (URSP) information transmitted by the Packet Control Function (PCF) entity;

[0180] Step 22: Based on the URSP information, create a Protocol Data Unit Session (PDU Session) for the non-GBR QoS Flow that does not guarantee bit rate QoS.

[0181] Step 23: Transmit the non-GBR QoS Flow on the PDU Session; wherein the rate parameter information of the non-GBR QoS Flow is without rate limit; the URSP information includes: indication information instructing the terminal to create a PDU Session, service flow description information of the service for which a PDU Session needs to be created, and route description information of the route used to create the PDU Session.

[0182] Specifically, the indication information includes an indication value. If the indication value is a first value, it indicates that the terminal is instructed to create a PDU Session; if the indication value is a second value, it indicates that the terminal is instructed not to create a PDU Session; and / or,

[0183] The service flow description information includes service flow IP address information, service identification information, and / or website URL information; and / or,

[0184] The routing description information includes slice information, data network name (DNN) information, PDU session type information, time information, and / or location information.

[0185] The information transmission method provided in this embodiment of the invention receives User Routing Policy (URSP) information transmitted by a Packet Control Function (PCF) entity; creates a Protocol Data Unit (PDU) Session for a non-GBR QoS Flow that does not guarantee bit rate QoS based on the URSP information; and transmits the non-GBR QoS Flow on the PDU Session. The rate parameter information of the non-GBR QoS Flow is unlimited. The URSP information includes: an instruction to the terminal to create a PDU Session, service flow description information of the service for which a PDU Session needs to be created, and route description information of the route used to create the PDU Session. This method enables the creation of a new PDU Session for a non-GBR QoS Flow with differentiated rate control requirements, and the transmission of the non-GBR QoS Flow on the newly created PDU Session. This satisfies the differentiated rate control requirements of the non-GBR QoS Flow, achieves separate control of the non-GBR QoS Flow, avoids configuring flow-level MBRs and rule priorities per flow, and thus guarantees non-GBR QoS. The flexibility, maintainability, and implementability of the differentiated rate control for Flow effectively solve the problem of poor flexibility, maintainability, and implementability in existing technologies for differentiated rate control of non-GBR QoSFlow.

[0186] This invention also provides an information transmission method applied to a business operation support system, such as... Figure 3 As shown, it includes:

[0187] Step 31: Send policy subscription information to the Packet Control Function (PCF) entity; wherein the policy subscription information includes first information, or the first information and second information; the first information includes: user identification information and policy coding information; the second information includes: service flow related information.

[0188] The information transmission method provided in this embodiment of the invention sends policy subscription information to the Packet Control Function (PCF) entity. The policy subscription information includes first information, or the first information and second information. The first information includes user identification information and policy coding information. The second information includes service flow related information. This supports the PCF entity in generating a URSP (Ultimate Request for Service) that will trigger the terminal to create a new PDU Session for a non-GBR QoS Flow with differentiated rate control requirements. The PCF entity then transmits this URSP to the terminal, instructing the terminal to create a new PDU Session for the non-GBR QoS Flow with differentiated rate control requirements and transmit the non-GBR QoS Flow on the newly created PDU Session. This satisfies the differentiated rate control requirements of the non-GBR QoS Flow, enabling separate control of the non-GBR QoS Flow. This avoids configuring flow-level MBR and rule priorities per flow, thus ensuring flexibility, maintainability, and implementability in the differentiated rate control of non-GBR QoS Flows. This effectively solves the problem of poor flexibility, maintainability, and implementability in the differentiated rate control of non-GBR QoS Flows in the prior art.

[0189] The service flow related information includes at least one of the following: service identification information; application identification information; service server IP address information; application server IP address information; URL information; and data network access identifier (DNAI) information.

[0190] The information transmission method provided in the embodiments of the present invention will be further described below in conjunction with multiple aspects such as the PCF entity, the terminal, and the business operation support system. Hereinafter, the PCF entity is referred to as PCF and the business operation support system is referred to as BOSS.

[0191] To address the aforementioned technical problems, embodiments of the present invention provide an information transmission method, specifically a rate control method. By forming a URSP that will inevitably trigger the UE (terminal) to establish a new PDU Session for non-GBR QoS Flows with differentiated rate control requirements, the method solves the problems of poor flexibility, maintainability, and implementability in differentiated rate control of non-GBR QoS Flows.

[0192] Specifically, the solutions provided in the embodiments of the present invention can be as follows: Figure 4 As shown, it includes:

[0193] Step 41: Configure relevant policies or policy templates for PCF;

[0194] Specifically, for non-GBR QoS Flows with differentiated rate control requirements, PCF configures relevant policies or policy templates.

[0195] Step 42: BOSS performs policy signing, and the obtained policy signing information includes user identification information and policy coding information; optionally, it may include business flow related information.

[0196] Specifically, regarding policy-based subscriptions: For non-GBR QoS flows with differentiated rate control requirements, users subscribe to policies on the BOSS side, such as allowing unlimited rate for a specific service. The policy subscription information includes: user identification information and policy encoding information, optionally including: service flow-related information (this information can also be generated by the PCF itself), and the service flow-related information includes at least, but is not limited to, at least one of the following application-related information: service identification information, application identification information, service server IP address information, application server IP address information, URL information, and data network access identifier (DNAI) information.

[0197] Step 43: BOSS sends strategy contract information to PCF;

[0198] In other words, the BOSS transmits the contract information (i.e., the strategy contract information) to the PCF.

[0199] Step 44: The PCF generates URSP rules based on the policy subscription information and sends them to the UE through the Access and Mobility Management Function (AMF) (entity).

[0200] Specifically, the PCF, based on the policy subscription information from step 42 (which may include policy coding information and service flow related information), forms URSP rules and sends them to the UE through the AMF. The URSP rules contain information instructing the UE to establish a new PDU session (i.e., the aforementioned instruction information), and also include, but are not limited to, service flow information (i.e., the aforementioned service flow description information, which can also be understood as non-GBR QoS Flow information with differentiated management requirements) and routing description information (i.e., the routing description information of the routes used to create the PDU Session).

[0201] More specifically, the information in this URSP rule includes at least three parts:

[0202] (1) Instruction information for the UE to create a new PDU Session, which indicates whether the UE needs to create a PDU Session, such as 1 for needing to create one and 0 for not needing to create one.

[0203] (2) Service flow description information, used to inform the UE which specified services to create a new PDU Session. Service flow information may include at least one of the following: service flow IP address information, service identification information, URL information, etc.

[0204] (3) Route description information, which is used to inform the UE of the route for creating a new PDU session. The route description information may include at least one of the following: slice information, data network name (DNN) information, PDU session type information, time information, location information, etc.

[0205] Furthermore, regarding step 44, the timing of generating a new URSP and distributing the URSP rule to the UE via the AMF can be achieved using any of the following methods:

[0206] Option A: After receiving the policy subscription information, the PCF determines that it is a non-GBR QoS Flow service with differentiated rate control requirements based on the policy encoding information. Then, it generates a URSP policy containing information instructing the UE to create a new PDU session and immediately triggers the transmission of the policy to the UE through the AMF.

[0207] Option B: After receiving the policy subscription information, the PCF determines whether the current PDU session can meet the requirements of non-GBR QoS Flow with differentiated rate control based on the policy encoding information and the current PDU Session's service flow information. If it does not meet the requirements, a URSP policy containing information instructing the UE to create a new PDU session is generated and transmitted to the UE through the AMF. If it meets the requirements, a new URSP is not generated for the time being, and the system continues to check whether the requirements are met (i.e., whether a new URSP needs to be generated). If the requirements are not met, a URSP policy containing information instructing the UE to create a new PDU session is generated and transmitted to the UE through the AMF.

[0208] For example, if the current PDU session's session AMBR has been adjusted to a rate-limited value, it cannot meet the requirement of unlimited rate for targeted services. In this case, the PCF generates a URSP policy containing information instructing the UE to create a new PDU session for the non-GBR QoS Flow corresponding to the targeted service, and passes it to the UE through the AMF. Otherwise, if the current PDU session's session AMBR has not been adjusted to a rate-limited value and can still meet the requirement of unlimited rate for targeted services, a new URSP will not be generated for the time being. When the session AMBR value changes to a point where it can no longer meet the requirement, a URSP policy containing information instructing the UE to create a new PDU session will be generated and passed to the UE through the AMF.

[0209] Among them, the policy coding information itself can cover the policy subscription requirements (e.g., iQiyi's policy coding 2001 can cover its required rate information of 10Mbps; while iQiyi's policy coding 2002 can cover its required rate information of 20Mbps). The service flow information here can include the rate control information of the current PDU session (e.g., Session AMBR; to determine whether the current rate control can meet the differentiated requirements, please refer to the examples above).

[0210] Step 45: After receiving the URSP rule from the PCF, the UE creates a new PDU session according to the new PDU session instruction, and transmits the non-GBR QoS Flow for the differentiated rate control requirement on the new PDU session; the rate of the non-GBR QoS Flow will no longer be limited by the session-AMBR parameter control of other PDU sessions containing non-GBR QoS Flows.

[0211] As can be seen from the above, the solutions provided by the embodiments of the present invention involve:

[0212] 1. Functions of the PCF side:

[0213] (1) It is necessary to support the formation of URSP rules that include instructions for UEs to create new PDU sessions based on policy subscription information.

[0214] (2) For scheme A in step 44, it is necessary to support the immediate generation of URSP rules containing instructions for the UE to create a new PDU session after receiving the policy subscription information, and immediately trigger the process to be transmitted to the UE through AMF.

[0215] (3) For Scheme B in step 44, it is necessary to support the determination of whether the current PDU session can meet the requirements of non-GBR QoS Flow with differentiated rate control requirements after receiving the policy subscription information, based on the policy encoding information and the service flow information of the current PDU Session. If it does not meet the requirements, a URSP policy containing information indicating that the UE should create a new PDU session should be generated and transmitted to the UE through the AMF. If it meets the requirements, a new URSP should not be generated for the time being. When it cannot meet the requirements, a URSP policy containing information indicating that the UE should create a new PDU session should be generated.

[0216] 2. Functions on the UE side:

[0217] (1) It is required to support the creation of a new PDU session after receiving the URSP rule of the PCF, and to transmit the non-GBR QoS Flow of the differentiated rate control requirement on the new PDU session.

[0218] 3. Functions on the BOSS side:

[0219] (1) Policy signing information must be supported, which may include: business flow related information, and the business flow related information includes at least one of the following: business identification information, application identification information, business server IP address information, application server IP address information, URL information, DNAI information, etc.

[0220] In summary, compared with existing technologies, this solution solves the problem of poor flexibility, maintainability, and implementability in the differentiated rate management of non-GBR QoS Flows by proposing a URSP scheme that will always trigger the UE to create a new PDU Session for non-GBR QoS Flows with differentiated rate control requirements. This solution has very practical guiding significance for real-world deployment and business development.

[0221] This invention also provides an information transmission device applied to a Packet Control Function (PCF) entity, such as... Figure 5 As shown, it includes:

The URSP information includes: indication information instructing the terminal to create a PDU Session, service flow description information of the service requiring PDU Session creation, and route description information of the route used to create the PDU Session. This enables the device to generate an URSP that will definitely trigger the terminal to create a new PDU Session for a non-GBR QoS Flow with differentiated rate control requirements, and transmits this URSP to the terminal. This instructs the terminal to create a new PDU Session for the non-GBR QoS Flow with differentiated rate control requirements, and transmits the non-GBR QoS Flow on the newly created PDU Session to meet the differentiated rate control requirements of the non-GBR QoS Flow. This achieves separate control of the non-GBR QoS Flow, avoids configuring flow-level MBRs and rule priorities per flow, and thus guarantees non-GBR QoS. The flexibility, maintainability, and implementability of the differentiated rate control for flow effectively solve the problem of poor flexibility, maintainability, and implementability in existing technologies for differentiated rate control of non-GBR QoS flows.

The policy subscription information includes first information, or the first information and second information. The first information includes user identification information and policy coding information. The second information includes service flow related information. This supports the PCF entity in forming a URSP (Ultimate Request for Service) that will inevitably trigger the terminal to create a new PDU Session for a non-GBR QoS Flow with differentiated rate control requirements, and transmits it to the terminal. This instructs the terminal to create a new PDU Session for the non-GBR QoS Flow with differentiated rate control requirements, and transmit the non-GBR QoS Flow on the newly created PDU Session to meet the differentiated rate control requirements of the non-GBR QoS Flow.

The URSP information includes: an instruction to the terminal to create a PDU Session, a service flow description of the service requiring PDU Session creation, and a route description of the route used to create the PDU Session. This enables the PCF entity to generate an URSP that will definitely trigger the terminal to create a new PDU Session for a non-GBR QoS Flow with differentiated rate control requirements, and transmits this URSP to the terminal. This instructs the terminal to create a new PDU Session for the non-GBR QoS Flow with differentiated rate control requirements, and transmits the non-GBR QoS Flow on the newly created PDU Session to meet the differentiated rate control requirements of the non-GBR QoS Flow. This achieves separate control of the non-GBR QoS Flow, avoids configuring flow-level MBRs and rule priorities per flow, and thus guarantees non-GBR QoS.

This operational data can be collected as a single dataset or distributed across different locations (including different storage devices), and can exist, at least in part, solely as electronic signals within the system or network.

[0294] When a module can be implemented using software, considering the current level of hardware technology, modules that can be implemented in software can be implemented using hardware circuits by those skilled in the art to achieve the corresponding functions, without considering cost. These hardware circuits include conventional very-large-scale integrated circuits (VLSI) or gate arrays, as well as existing semiconductors such as logic chips and transistors, or other discrete components. Modules can also be implemented using programmable hardware devices, such as field-programmable gate arrays, programmable array logic, and programmable logic devices.

[0295] The above describes the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
