Description

Information transmission and acquisition method, device and communication equipment

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on September 18, 2023, with application number 202311201765.7 and application name “Information Transmission, Acquisition Method, Device and Communication Equipment”, the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to an information transmission and acquisition method, apparatus, and communication equipment. Background Art

[0003] After the Radio Access Network (RAN) becomes service-oriented (N2 interface service-oriented, RAN control plane service-oriented, etc.), the anchor point between the network and the RAN is no longer the Access and Mobility Management Function (AMF). The RAN can exchange signaling and establish processes with any required Network Function (NF). For example, the RAN can interact with the AMF for mobility-related processes, with the Session Management Function (SMF) for session-related processes, and with the Location Management Function (LMF) for positioning-related processes. The SMF then sends related Quality of Service (QoS) control information to the RAN and user equipment (UE) through the AMF, or the AMF is responsible for QoS management. This no longer meets the system requirements of the RAN service-oriented architecture and prevents normal business operations.

Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0147] The terms "first," "second," and the like in the specification and claims of the present disclosure are used to distinguish similar objects and are not necessarily used to describe a particular order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein may be implemented in a sequence other than those illustrated or described herein.

[0148] In the embodiments of the present disclosure, the term "and / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship. In the embodiments of the present disclosure, the term "plurality" refers to two or more, and other quantifiers are similar.

[0149] In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0150] The following is a brief description of the relevant concepts mentioned in this disclosure.

[0151] 1. Quality of Service (QoS)

[0152] QoS is a description of service transmission quality and also a guarantee mechanism for service transmission quality. Its purpose is to provide end-to-end service quality assurance for various services based on their different needs.

[0153] The concept of QoS flow is introduced in the QoS model of the fifth generation mobile communication technology (5G). QoS flow is the minimum granularity of QoS processing. 5G performs QoS processing based on the granularity of the flow, and the network side forwards data packets based on the QoS flow identifier (QFI).

[0154] 2. QoS Management

[0155] 5GC and NG-RAN ensure service quality (such as reliability and target latency) by mapping packets to appropriate QoS flows and data radio bearers (DRBs). This involves a two-step mapping process: the packet filtering mechanism at the Non-Access Stratum (NAS) layer is responsible for mapping application-layer uplink and downlink user plane data (Internet Protocol (IP) flows) to QoS flows; and the Access Stratum (AS) layer is responsible for mapping uplink and downlink QoS flows to DRBs.

[0156] At the NAS layer, for any QoS flow:

[0157] SMF provides QoS configuration (Profile) and its corresponding QFI to RAN through AMF, or pre-configures the service quality profile (QoS Profile) in the access network. Whether a QoS flow is of GBR type or non-GBR type depends on its corresponding QoS profile. QoS profile contains QoS parameters and QoS attribute information (such as 5QI, ARP, GFBR, MFBR, maximum packet loss rate and RQA, etc.) that the QoS flow needs to meet during transmission. RAN maps QoS flows to DRBs based on QoS profiles and determines how data is processed on the air interface. It can be seen that QoS Profile is used on the RAN side.

[0158] The SMF can provide one or more Quality of Service (QoS) rules to the UE through the AMF, pre-configure them on the UE, or derive them through reflective QoS. The UE classifies and marks uplink user plane data based on the QoS rules, that is, determines the association between uplink services and QoS flows. It can be seen that QoS rules are for the UE.

[0159] The SMF provides one or more upstream and downstream packet detection rules (PDRs) to the UPF. The PDRs contain information for classifying and processing packets arriving at the UPF.

[0160] A QoS rule or PDR contains a packet filter set, which is used to specify a QoS flow for user-plane data. This is done by matching the header characteristics (IP header or Ethernet header) of the received application / service layer data with the packet filter entries (i.e., packet filters) in the packet filter set. A successful match identifies the corresponding QoS flow. This process maps application / service layer data to a QoS flow.

[0161] At the AS level, the Data Radio Bearer (DRB) defines the message processing on the air interface (Uu). Messages transmitted on the same DRB have the same message forwarding processing.

[0162] In the downlink, the RAN maps downlink QoS flows to DRBs based on the QFI and its associated QoS profile. The RAN may establish separate DRBs for different QoS flows with different packet forwarding processing requirements. Multiple QoS flows belonging to the same packet data unit (PDU) session can also be mapped to the same DRB.

[0163] In the uplink, the UE determines the mapping rules of uplink QoS flows to DRBs in two ways:

[0164] (1) Configuring the mapping rules of QoS flows to DRBs to the UE through Radio Resource Control (RRC) signaling;

[0165] (2) The UE obtains the mapping rule through the reflective QoS flow-to-DRB mapping. That is, the UE learns the mapping of the corresponding downlink QoS flow to the DRB based on the received downlink data and applies it to the uplink. The UE always applies the most recently updated matching rule, regardless of whether this rule is derived through reflective QoS mapping or explicitly configured through RRC.

[0166] FIG1 shows a block diagram of a wireless communication system to which the embodiments of the present disclosure are applicable. The wireless communication system includes a terminal 11 and a network-side device 12 .

As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of this disclosure, only the base station in the NR system is used as an example to introduce, and the specific type of the base station is not limited.The core network equipment may include but is not limited to at least one of the following: core network node, core network function, mobility management entity (MME), access mobility management function (AMF), session management function (SMF), user plane function (UPF), policy control function (PCF), policy and charging rules function unit (PCRF), edge application service discovery function (EASDF), unified data management (UDM), unified data storage (UDR), home user server (HSS), centralized network configuration (CNC), network storage function (NRF), network exposure function (NEF), local NEF (L-NEF), binding support function (BSF), application function ( Function (AF), Sensing Function (SF), etc.

[0167] The following describes embodiments of the present disclosure in conjunction with the accompanying drawings. The measurement and measurement configuration methods, apparatuses, terminals, and network devices provided in the embodiments of the present disclosure can be applied to wireless communication systems. The wireless communication system can be a system that uses fifth-generation (5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art will appreciate that the 5G NR system is only an example and not a limitation.

[0168] The embodiments of the present disclosure provide a measurement and measurement configuration method, apparatus, terminal, and network equipment to solve the QoS information transmission problem based on RAN service, reduce signaling transmission, and lower transmission delay.

[0169] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0170] As shown in FIG2 , an embodiment of the present disclosure provides an information transmission method, which is performed by a first network function and includes:

[0171] Step S201: Sending a quality of service configuration file and / or quality of service rules to an access network device; and / or

[0172] sending the quality of service rules to a second network function, the second network function being configured to implement user plane management;

[0173] The first network function is used to implement session management, for example, the first network function is the SMF in 5G.

[0174] It should be noted that the QoS profile is used on the access network side. That is, the QoS profile is used by the access network equipment. The access network equipment uses the QoS profile to map QoS flows to data radio bearers (DRBs) and determine how data is processed on the air interface. The QoS rule is used by the terminal. That is, the terminal needs to classify and mark uplink user plane data based on the QoS rule, that is, determine the association between uplink services and QoS flows.

[0175] In some embodiments, in one implementation, the specific implementation of sending the quality of service configuration and / or quality of service rules to the access network device includes:

[0176] Sending a quality of service configuration file and / or quality of service rules to an access network device by invoking a service-oriented interface with the access network;

[0177] It should be noted that, in this case, the first network function directly sends the quality of service configuration file and / or quality of service rules to the access network device through the service-based interface.

[0178] In some embodiments, in this case, if the access network device receives the quality of service rule directly from the first network function, the access network device needs to send the quality of service rule to the terminal.

[0179] It should be noted that, for the first network function, in one case, if it needs to transmit a quality of service configuration file, the quality of service configuration file can only be directly transmitted to the access network device by calling the service-based interface between the access network; in another case, if it needs to transmit quality of service rules, one of the following methods can be used:

[0180] 1. Transmitting quality of service rules directly to access network devices by invoking the service-oriented interface between the access network and the access network;

[0181] 2. Transmit the quality of service rules to the second network function, and send the quality of service rules to the terminal through the second network function.

[0182] In some embodiments, the second network function may be, for example, a UPF. Since the quality of service rules are directly used by the terminal and the second network function can manage the user plane, the quality of service rules may be transmitted to the terminal via the second network function.

[0183] In some embodiments, upon receiving the quality of service rule, the second network function needs to first send the quality of service rule to the access network device. In some embodiments, the second network function and the access network device may use a point-to-point interface to transmit the quality of service rule, or a service-based interface to transmit the quality of service rule.

[0184] In some embodiments, in this case, if the access network device receives the quality of service rule directly from the second network function, the access network device needs to send the quality of service rule to the terminal.

[0185] In some embodiments, in one implementation, the specific implementation of sending the quality of service rule to the second network function includes:

[0186] Send a session establishment request or a session modification request to the second network function, where the session establishment request or the session modification request includes a quality of service rule.

[0187] That is to say, the quality of service rules can be sent to the second network function through a session establishment request or a session modification request. For example, when the second network function is UPF, the quality of service rules can be sent to UPF through an N4 session establishment request or an N4 session modification request.

[0188] In some embodiments, in one implementation, the method of the embodiment of the present disclosure further includes:

[0189] receiving a PDU session establishment request message or a PDU session modification request message, where the PDU session establishment request message or the PDU session modification request message carries a quality of service requirement;

[0190] The quality of service configuration and / or quality of service rule is generated according to the quality of service requirement.

[0191] It should be noted that the quality of service configuration and / or quality of service rules are generated based on the PDU session of the terminal. In some embodiments, the terminal can send a PDU session establishment request message to the first network function to request the establishment of a PDU session. The PDU session establishment request message can carry a quality of service requirement. The quality of service requirement refers to the quality of service control information related to the PDU session that the terminal expects or allows. The quality of service control information includes but is not limited to quality of service configuration, quality of service rules, etc. The first network device can obtain the quality of service configuration and / or quality of service rules that need to be configured for the terminal based on the quality of service requirement. If the PDU session establishment request message does not carry the quality of service requirement, the first network function can generate the quality of service configuration and / or quality of service rules based on the rules obtained from the policy control function.

[0192] After the PDU session is established, the PDU session can also be modified. In some embodiments, the terminal can send a PDU session modification request message to the first network function to request modification of the PDU session. The PDU session modification request message can carry a quality of service requirement. The quality of service requirement refers to the quality of service control information related to the PDU session that the terminal expects or allows. The first network device can obtain the quality of service configuration and / or quality of service rules that need to be modified based on the quality of service requirement; if the PDU session modification request message does not carry the quality of service requirement, the first network function can generate a modified quality of service configuration and / or quality of service rules based on the rules obtained from the policy control function.

[0193] It should be noted that, as can be seen from the above description, the quality of service configuration and / or quality of service rules can be issued and updated. In some embodiments, after the PDU session of the terminal is released, the quality of service configuration and / or quality of service rules related to the released session also need to be deleted. In some embodiments, in one implementation, the method further includes:

[0194] During the PDU session release process, the quality of service information allocated when the PDU session is established for the terminal is deleted, where the quality of service information includes part or all of the information in the quality of service configuration file and / or quality of service rules.

[0195] It should be noted that during the PDU session release process, the first network function needs to delete part or all of the information in the quality of service profile and / or quality of service rules allocated to the terminal's PDU session, so as to reduce the memory occupied by the quality of service information.

[0196] In some embodiments, in one implementation, during the PDU session release process, deleting the quality of service information allocated when establishing the PDU session for the terminal includes:

[0197] Receiving a PDU session release request sent by the terminal through the access network device;

[0198] According to the PDU session release request, the service quality information allocated when the PDU session is established for the terminal is deleted.

[0199] That is to say, when the terminal needs to release the PDU session, it will send a PDU session release request to the first network function through the access network device. The first network function can delete the relevant information after receiving the PDU session release request. In some embodiments, the PDU session release request includes the service quality information that needs to be released; the first network function obtains the service quality information that needs to be released included in the PDU session release request and deletes the service quality information; in some embodiments, if the PDU session release request does not include the service quality information that needs to be released, the first network function can delete all service quality profiles and / or service quality rules related to the released PDU session. As for the case where the service quality information that needs to be released is not included in the PDU session release request, which service quality information needs to be deleted can be configured on the network side or agreed upon by the protocol.

[0200] In some embodiments, after releasing the PDU session, the terminal also needs to delete part or all of the information in the quality of service rule allocated to it by the first network device.

[0201] In some embodiments, during the process of releasing the PDU session, the access network device also needs to delete part or all of the information in the service quality profile allocated to it by the first network device. The access network device can delete the relevant information when it receives the PDU session release request sent by the terminal, or it can delete the relevant information when it receives the PDU session release response sent by the first network function.

[0202] The following takes the case where the first network function is SMF, the second network function is UPF, and the first network function issues QoS profile and QoS Rule as an example to illustrate the specific application of the embodiment of the present disclosure.

[0203] Application Scenario 1: Under the RAN service-oriented architecture, SMF directly sends the QoS profile to the access network equipment and sends the QoS Rule to the terminal.

[0204] As shown in Figure 3, the specific implementation process includes:

[0205] Step 31: The SMF sends the QoS profile and QoS rule to the access network device by calling the service-oriented interface between the SMF and the access network.

[0206] For example, the SMF sends a service quality information transfer response (Nran_QoS Info Transfer) message to the access network device, where the message carries a QoS profile and a QoS rule.

[0207] The QoS profile is used by the access network device, and the QoS rule is transparently transmitted by the access network device to the terminal for use by the terminal.

[0208] Step 32: The access network device sends a radio resource control downlink transfer (RRC Downlink Transfer) message to the terminal, where the message carries a QoS rule.

[0209] Step 33: After receiving the QoS rule sent by the access network device, the terminal sends a radio resource control downlink transfer response (RRC Downlink Transfer Ack) message to the access network device.

[0210] Step 34: After the access network device receives the RRC Downlink Transfer Ack message sent by the terminal, the access network device sends a QoS Info Transfer Ack message to the SMF through the service-based interface.

[0211] Application scenario 2: In the access network service-oriented architecture, SMF sends the QoS rule assigned to the terminal to the terminal through UPF.

[0212] As shown in Figure 4, the specific implementation process includes:

[0213] Step 41: The SMF sends the QoS profile to the access network device by calling the service-based interface between the SMF and the access network.

[0214] The QoS profile is used by access network devices to map QoS flows to DRBs.

[0215] Step 42: SMF sends an N4 session modification request message to UPF, which carries the QoS rule allocated to the terminal.

[0216] Step 43: After receiving the QoS rule assigned by SMF, UPF replies with N4 session modification response message to SMF;

[0217] Step 44: UPF sends a QoS Configuration Request message to the terminal. The message carries the QoS rule assigned to the terminal. Whether the UPF and the access network device use a point-to-point interface or a service-based interface for message transmission is not limited here.

[0218] Step 45: After receiving the QoS rule assigned by the SMF, the terminal replies with a QoS Configuration Ack message to the UPF.

[0219] Step 46: The access network device invokes the service-based interface between the access network device and the SMF and sends a confirmation message to the SMF. For example, the confirmation message may be a quality of service information transfer response (Nran_QoS Info Transfer Ack) message.

[0220] Application scenario 3: Under the access network service-oriented architecture, when the terminal initiates a PDU session modification, the SMF directly updates the QoS profile to the access network device and updates the QoS Rule to the terminal.

[0221] As shown in Figure 5, the specific implementation process includes:

[0222] Step 51: When the QoS information changes or is updated, the SMF calls the service-based interface to send a service quality information update transfer (Nran_QoS Info Update Transfer) message to the access network device. The message carries the QoS profile and QoS rule.

[0223] Step 52: The access network device sends a radio resource control downlink update transfer (RRC Downlink Update Transfer) message to the terminal, where the message carries a QoS rule.

[0224] Step 53: After receiving the QoS rule, the terminal sends a radio resource control uplink update transfer response (RRC Uplink Update Transfer Ack) message to the access network device.

[0225] Step 54: After receiving the confirmation message sent by the terminal, the access network device calls the service-based interface to send a confirmation message to the SMF. For example, the confirmation message may be a service quality information update transfer response (Nran_QoS Info Update Transfer Ack) message.

[0226] Application Scenario 4: QoS Information Deletion

[0227] This is mainly for nodes that store and manage QoS information. When a terminal initiates a PDU session release request, the QoS information needs to be deleted here. For example, SMF and access network equipment need to delete their own stored QoS information when receiving a PDU session release request sent by the terminal.

[0228] As shown in Figure 6, the specific implementation process includes:

[0229] Step 61: The terminal initiates a PDU session release request to the access network device and the core network.

[0230] Step 62: SMF deletes the QoS information allocated when establishing the PDU session for the terminal.

[0231] Step 63: The SMF and the access network device send a PDU session release response message to the terminal.

[0232] Step 64: After receiving the PDU session release response message, the access network device deletes the QoS profile.

[0233] Step 65: After receiving the PDU session release response message, the terminal deletes the QoS rule allocated by the SMF.

[0234] In some embodiments, the access network device may also delete the QoS profile when receiving the PDU session release request, that is, at this time, the access network device deletes the QoS profile before the SMF deletes the QoS information.

[0235] Application Scenario 5: Carrying QoS Information When a Terminal Initiates a Session

[0236] As shown in Figure 7, the specific implementation process includes:

[0237] Step 71: The terminal sends a PDU session establishment request message to the SMF;

[0238] The PDU session establishment request message carries its own QoS requirements.

[0239] Step 72: The SMF generates a QoS profile and a QoS rule based on the obtained QoS requirements and the rules obtained from the PCF.

[0240] Step 73: The SMF sends the QoS profile and QoS rule to the access network device by calling the service-based interface between the SMF and the access network.

[0241] The QoS profile is used by the access network device, and the QoS rule is transparently transmitted by the access network device to the terminal for use by the terminal.

[0242] Step 74: The access network device sends an RRC Downlink Transfer message to the terminal, where the message carries a QoS rule.

[0243] Step 75: After receiving the QoS rule sent by the access network device, the terminal sends an RRC Downlink Transfer Ack message to the access network device.

[0244] Step 76: After the access network device receives the RRC Downlink Transfer Ack message sent by the terminal, the access network device sends a QoS Info Transfer Ack message to the SMF through the service-based interface.

[0245] Step 77: SMF sends a session establishment response message to the terminal, indicating that the QoS control of the terminal has been completed.

[0246] Application Scenario 6: The terminal carries updated QoS information when initiating session modification

[0247] As shown in Figure 8, the specific implementation process includes:

[0248] Step 81: The terminal sends a PDU session modification request message to the SMF;

[0249] The PDU session modification request message carries its own QoS requirements.

[0250] Step 82: When the QoS information changes or is updated, the SMF calls the service-based interface to send an Nran_QoS Info Update Transfer message to the access network device, which carries the QoS profile and QoS rule.

[0251] Step 83: The access network device sends an RRC Downlink Update Transfer message to the terminal, where the message carries a QoS rule.

[0252] Step 84: After receiving the QoS rule, the terminal sends an RRC Uplink Update Transfer Ack message to the access network device.

[0253] Step 85: After receiving the confirmation message sent by the terminal, the access network device calls the service-based interface to send a confirmation message to the SMF. For example, the confirmation message may be an Nran_QoS Info Update Transfer Ack message.

[0254] Step 86: SMF sends a session modification response message to the terminal, indicating that the QoS control of the terminal has been completed.

[0255] Application Scenario 7: QoS Information Deletion Initiated by Terminal

[0256] As shown in Figure 9, the specific implementation process includes:

[0257] Step 91: The terminal initiates a PDU session release request to the access network device and the core network, carrying the QoS information to be deleted. The QoS information includes part or all of the information in the QoS profile and QoS rule.

[0258] Step 92: SMF deletes the QoS information allocated when establishing the PDU session for the terminal.

[0259] Step 93: The SMF and the access network device send a PDU session release response message to the terminal.

[0260] Step 94: After receiving the PDU session release response message, the access network device deletes the QoS profile.

[0261] Step 95: After receiving the PDU session release response message, the terminal deletes the QoS rule allocated by the SMF.

[0262] In some embodiments, the access network device may also delete the QoS profile when receiving the PDU session release request, that is, at this time, the access network device deletes the QoS profile before the SMF deletes the QoS information.

[0263] Application Scenario 8: QoS information initiated by the terminal is sent through the UPF

[0264] This embodiment is in the access network equipment service architecture. SMF sends the QoS rule assigned to the terminal to the terminal through UPF.

[0265] As shown in Figure 10, the specific implementation process includes:

[0266] Step 1001: The terminal sends a PDU session establishment request message to the SMF;

[0267] The PDU session establishment request message carries its own QoS requirements.

[0268] Step 1002: The SMF generates QoS information based on the QoS requirements sent by the terminal.

[0269] Step 1003: The SMF sends the QoS profile to the access network device by calling the service-oriented interface between the SMF and the access network.

[0270] The QoS profile is used by access network devices to map QoS flows to DRBs.

[0271] Step 1004: SMF sends an N4 session modification request message to UPF, which carries the QoS rule allocated to the terminal.

[0272] Step 1005: After receiving the QoS rule assigned by the SMF, the UPF replies with an N4 session modification response message.

[0273] Step 1006: The UPF sends a QoS Configuration Request message to the terminal, which carries the QoS rule allocated to the terminal.

[0274] There is no restriction on whether the UPF and the access network device use a point-to-point interface or a service-based interface for message transmission.

[0275] Step 1007: After receiving the QoS rule assigned by the SMF, the terminal replies with a QoS Configuration Ack message to the UPF.

[0276] Step 1008: The access network device calls the service-based interface between SMFs to send a confirmation message to the SMF. For example, the confirmation message may be an Nran_QoS Info Transfer Ack message.

[0277] Step 1009: SMF sends a session establishment response message to the terminal, indicating that the QoS control of the terminal has been completed.

[0278] It should be noted that the embodiments of the present disclosure propose a QoS control method under the RAN service-oriented architecture, adopt a new QoS control mechanism, solve the transmission problem of service quality profiles and / or service quality rules based on RAN service-oriented architecture, and reduce signaling transmission and transmission delay compared with the existing 5G system.
