Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information transmission and acquisition method, device and communication equipment. Background Art

[0002] After the Radio Access Network (RAN) is service-oriented (N2 interface service-oriented, RAN control plane service-oriented, etc.), the anchor point between the network and RAN is no longer the Access and Mobility Management Function (AMF). RAN can interact with any network function (NF) in need for signaling and process establishment. For example, RAN and AMF can interact with mobility-related processes, with Session Management Function (SMF) for session-related processes, and with Location Management Function (LMF) for positioning-related processes.

[0144] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0145] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein, for example, are implemented in a sequence other than those illustrated or described herein.

[0146] In the embodiments of the present application, the term "and / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0147] In the embodiments of the present application, 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 application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0148] The relevant concepts mentioned in this application are briefly described below.

[0149] 1. Quality of Service (QoS)

[0150] QoS is an expression of service transmission quality and also a guarantee mechanism for service transmission quality. Its purpose is to provide end-to-end service quality guarantee for various services according to their different needs.

[0151] The concept of QoS flow is introduced in the 5G QoS model. QoS flow is the minimum granularity of QoS processing. 5G performs QoS processing based on the granularity of flow, and the network side forwards data packets based on the QoS flow identifier (QFI).

[0152] 2. QoS Management

[0153] 5GC and NG-RAN ensure the quality of service (such as reliability and target latency) by mapping messages to appropriate QoS flows and data radio bearers (DRBs). This involves two steps of mapping: the message filtering mechanism at the NAS layer is responsible for mapping the uplink and downlink user plane data (IP flows) related to the application layer to QoS flows; the AS layer is responsible for mapping the uplink and downlink QoS flows to DRBs.

[0154] At the NAS level, for any QoS flow:

[0155] SMF provides QoS configuration (Profile) and its corresponding QFI to RAN through AMF, or pre-configures 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 profile and determines how data is processed on the air interface. It can be seen that QoS Profile is used on the RAN side.

[0156] SMF can provide one or more QoS rules to UE through AMF, pre-configure on UE, or derive one or more QoS rules through reflective QoS. UE classifies and marks uplink user plane data based on QoS rules, that is, determines the association between uplink services and QoS flows. It can be seen that QoS rules are for UE.

[0157] SMF provides one or more upstream and downstream PDRs (Packet Detection Rules) to UPF. PDR contains information for classifying and processing packets arriving at UPF.

[0158] QoS rule or PDR contains a packet filter set (Packet Filter Set), which is used to specify a QoS flow for user plane data. That is, based on the header features (IP header or Ethernet header) of the received application / service layer data, it is matched with the packet filter entry (Packet Filter) in the packet filter set. After a successful match, the corresponding QoS flow is found. This process is the process of mapping application / service layer data to QoS flow.

[0159] At the AS level, DRB (Data Radio Bearer) defines the message processing on the air interface (Uu). Messages transmitted on the same DRB have the same message forwarding processing.

[0160] In the downlink, RAN maps the downlink QoS flow to the DRB based on the QFI and its associated QoS Profile. RAN may establish independent DRBs for different QoS flows with different message forwarding processing requirements. Multiple QoS flows belonging to the same packet data unit (PDU) session can also be mapped to the same DRB.

[0161] In the uplink, the UE determines the mapping rules of the uplink QoS flow to the DRB in two ways:

[0162] (1) The mapping rules of QoS flows to DRBs are displayed to the UE through RRC signaling;

[0163] (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.

[0165] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings. The measurement, measurement configuration method, device, terminal and network equipment provided in the embodiments of the present application can be applied to a wireless communication system. The wireless communication system can be a system using the fifth generation (5th Generation, 5G) mobile communication technology (hereinafter referred to as a 5G system). Those skilled in the art can understand that the 5G NR system is only an example and is not a limitation.

[0166] The embodiments of the present application provide a measurement and measurement configuration method, apparatus, terminal and network equipment to achieve the purpose of solving the QoS information transmission problem based on RAN service, reducing signaling transmission and lowering transmission delay.

[0167] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0168] like Figure 2 As shown, an embodiment of the present application provides an information transmission method, which is performed by a first network function and includes:

[0169] Step S201, sending a quality of service configuration file and / or quality of service rules to an access network device; and / or

[0171] The first network function is used to implement session management, for example, the first network function is the SMF in 5G.

[0172] 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, which maps the QoS flow to the data radio bearer (DRB) based on the QoS profile and determines how the data is processed on the air interface. The QoS rule is used for the terminal, that is, the terminal needs to classify and mark the uplink user plane data based on the QoS rule, that is, determine the association between the uplink service and the QoS flow.

[0173] Optionally, in one implementation, the specific implementation of sending the quality of service configuration and / or quality of service rule to the access network device includes:

[0174] Sending a quality of service configuration file and / or quality of service rules to an access network device by calling a service-oriented interface with the access network;

[0175] It should be noted that, in this case, the first network function directly sends the quality of service configuration file and / or the quality of service rule to the access network device through the service-oriented interface.

[0176] Optionally, in this case, if the access network device directly receives the quality of service rule from the first network function, the access network device needs to send the quality of service rule to the terminal.

[0177] It should be noted that, for the first network function, in one case, if it needs to transmit a service quality configuration file, the service quality configuration file can only be directly transmitted to the access network device by calling the service-oriented interface between the access network; in another case, if it needs to transmit a service quality rule, one of the following methods can be used:

[0178] 1. Transmit the service quality rules directly to the access network equipment by calling the service-oriented interface between the access network and the access network;

[0179] 2. Transmit the quality of service rule to the second network function, and send the quality of service rule to the terminal through the second network function.

[0180] Optionally, the second network function may be, for example, a UPF. Since the quality of service rule is directly used by the terminal and the second network function can implement user plane management, the quality of service rule may be transmitted to the terminal via the second network function.

[0181] Optionally, after receiving the quality of service rule, the second network function needs to send the quality of service rule to the access network device first. Optionally, the second network function and the access network device can use a point-to-point interface to transmit the quality of service rule, or use a service-oriented interface to transmit the quality of service rule.

[0182] Optionally, in this case, if the access network device directly receives the quality of service rule from the second network function, the access network device needs to send the quality of service rule to the terminal.

[0183] Optionally, in one implementation, the specific implementation of sending the quality of service rule to the second network function includes:

[0184] Sending a session establishment request or a session modification request to the second network function, wherein the session establishment request or the session modification request includes a quality of service rule.

[0185] That is to say, the quality of service rules can be sent to the second network function via 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 via an N4 session establishment request or an N4 session modification request.

[0186] Optionally, in one implementation, the method in the embodiment of the present application further includes:

[0187] receiving a PDU session establishment request message or a PDU session modification request message, wherein the PDU session establishment request message or the PDU session modification request message carries a quality of service requirement;

[0188] The quality of service configuration and / or quality of service rule is generated according to the quality of service requirement.

[0189] 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. Optionally, 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.

[0190] After the PDU session is established, the PDU session can also be modified. Optionally, 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.

[0191] It should be noted that, from the above description, it can be known that the quality of service configuration and / or quality of service rules can be issued and updated. Optionally, 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. Optionally, in one implementation, the method further includes:

[0192] During the PDU session release process, the service quality information allocated when the PDU session is established for the terminal is deleted, and the service quality information includes part or all of the information in the service quality configuration file and / or the service quality rule.

[0193] 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.

[0194] Optionally, in one implementation, the implementation of deleting the quality of service information allocated when establishing the PDU session for the terminal during the PDU session release process includes:

[0195] Receiving a PDU session release request sent by the terminal through an access network device;

[0196] According to the PDU session release request, the service quality information allocated when the PDU session is established for the terminal is deleted.

[0197] 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, and the first network function can delete the relevant information after receiving the PDU session release request. Optionally, the PDU session release request includes the service quality information that needs to be released; when the first network function obtains the service quality information that needs to be released included in the PDU session release request, it deletes the service quality information; optionally, 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 a network-side configuration or a protocol agreement.

[0198] Optionally, 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.

[0199] Optionally, 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.

[0200] 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, and the specific application of the embodiment of the present application is illustrated as follows.

[0201] Application Scenario 1: In the RAN service-oriented architecture, SMF directly sends QoS profile to the access network equipment and QoS Rule to the terminal.

[0202] like Figure 3 As shown, the specific implementation process includes:

[0203] Step 31, SMF sends QoS profile and QoS rule to the access network device by calling the service-oriented interface between the SMF and the access network;

[0204] For example, the SMF sends a service quality information transfer response (Nran_QoS Info Transfer) message to the access network device, and the message carries a QoS profile and a QoS rule.

[0205] 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.

[0206] Step 32: The access network device sends a radio resource control downlink transfer (RRC Downlink Transfer) message to the terminal, and the message carries a QoS rule.

[0207] 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.

[0208] 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-oriented interface.

[0209] Application scenario 2: In the access network service-oriented architecture, SMF sends the QoS rule assigned to the terminal to the terminal through UPF.

[0210] like Figure 4 As shown, the specific implementation process includes:

[0211] Step 41, SMF sends QoS profile to the access network device by calling the service-based interface between the SMF and the access network;

[0212] Among them, QoS profile is used by access network equipment for mapping between QoS flows and DRBs.

[0213] Step 42: SMF sends an N4 session modification request message to UPF, which carries the QoS rule allocated to the terminal.

[0214] Step 43: After receiving the QoS rule assigned by SMF, UPF replies N4 session modification response message to SMF;

[0215] 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.

[0216] Step 45: After receiving the QoS rule assigned by the SMF, the terminal replies with a QoS Configuration Ack message to the UPF.

[0217] Step 46: The access network device calls the service-based interface between the access network device and the SMF to send a confirmation message to the SMF. For example, the confirmation message may be a service quality information transfer response (Nran_QoS Info Transfer Ack) message.

[0218] 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.

[0219] like Figure 5 As shown, the specific implementation process includes:

[0220] Step 51: When the QoS message changes or is updated, the SMF calls the service-oriented interface to send a service quality information update transfer (Nran_QoS Info Update Transfer) message to the access network device, and the message carries a QoS profile and a QoS rule.

[0221] Step 52: The access network device sends a radio resource control downlink update transfer (RRC DownlinkUpdate Transfer) message to the terminal, where the message carries a QoS rule.

[0222] 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.

[0223] 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_QoSInfo Update Transfer Ack) message.

[0224] Application Scenario 4: QoS Information Deletion

[0225] When the node that stores and manages QoS information receives a PDU session release request initiated by the terminal, the QoS information needs to be deleted here. For example, SMF and access network equipment need to delete the QoS information they store when receiving the PDU session release request sent by the terminal.

[0226] like Figure 6 As shown, the specific implementation process includes:

[0227] Step 61: The terminal initiates a PDU session release request to the access network device and the core network.

[0228] Step 62: SMF deletes the QoS information allocated when establishing the PDU session for the terminal.

[0229] Step 63: The SMF and the access network device send a PDU session release response message to the terminal;

[0230] Step 64: After receiving the PDU session release response message, the access network device deletes the QoS profile.

[0231] Step 65: After receiving the PDU session release response message, the terminal deletes the QoS rule allocated by the SMF.

[0232] Optionally, 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.

[0233] Application Scenario 5: The terminal carries QoS information when initiating a session establishment

[0234] like Figure 7 As shown, the specific implementation process includes:

[0235] Step 71, the terminal sends a PDU session establishment request message to the SMF;

[0236] The PDU session establishment request message carries its own QoS requirements.

[0237] Step 72, SMF generates QoS profile and QoS rule according to the obtained QoS requirements and the rules obtained from PCF;

[0238] Step 73: SMF sends QoS profile and QoS rule to the access network device by calling the service-based interface between the SMF and the access network.

[0239] Among them, QoS profile is used by access network devices, and QoS rule is transparently transmitted by access network devices to terminals for use by terminals.

[0240] Step 74: The access network device sends an RRC Downlink Transfer message to the terminal, where the message carries a QoS rule.

[0241] Step 75: After receiving the QoS rule sent by the access network device, the terminal sends an RRCDownlink Transfer Ack message to the access network device.

[0242] 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.

[0243] Step 77: SMF sends a session establishment response message to the terminal, indicating that the QoS control of the terminal has been completed.

[0244] Application Scenario 6: The terminal carries updated QoS information when initiating session modification

[0245] like Figure 8 As shown, the specific implementation process includes:

[0246] Step 81, the terminal sends a PDU session modification request message to the SMF;

[0247] The PDU session modification request message carries its own QoS requirements.

[0248] 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.

[0249] Step 83: The access network device sends an RRC Downlink Update Transfer message to the terminal, and the message carries a QoS rule.

[0250] Step 84: After receiving the QoS rule, the terminal sends an RRC Uplink UpdateTransfer Ack message to the access network device.

[0251] 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.

[0252] Step 86: SMF sends a session modification response message to the terminal, indicating that the QoS control of the terminal has been completed.

[0253] Application Scenario 7: QoS Information Deletion Initiated by Terminal

[0254] like Fig. 9 As shown, the specific implementation process includes:

[0255] 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, where the QoS information includes part or all of the information in the QoS profile and QoS rule.

[0256] Step 92: SMF deletes the QoS information allocated when establishing the PDU session for the terminal.

[0257] Step 93: SMF and access network equipment send a PDU session release response message to the terminal.

[0258] Step 94: After receiving the PDU session release response message, the access network device deletes the QoS profile.

[0259] Step 95: After receiving the PDU session release response message, the terminal deletes the QoS rule allocated by the SMF.

[0260] Optionally, 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.

[0261] Application Scenario 8: QoS information initiated by the terminal is sent through UPF

[0262] In this embodiment, under the service-oriented architecture of access network equipment, SMF sends the QoS rule assigned to the terminal to the terminal through UPF.

[0263] like Fig.10 As shown, the specific implementation process includes:

[0264] Step 1001: The terminal sends a PDU session establishment request message to the SMF;

[0265] The PDU session establishment request message carries its own QoS requirements.

[0266] Step 1002: SMF generates QoS information based on the QoS requirements sent by the terminal.

[0267] Step 1003: SMF sends QoS profile to the access network device by calling the service-oriented interface between the SMF and the access network.

[0268] The QoS profile is used by access network devices to map QoS flows between DRBs.

[0269] Step 1004: SMF sends an N4 session modification request message to UPF, which carries the QoS rule allocated to the terminal.

[0270] Step 1005: After receiving the QoS rule assigned by SMF, UPF replies with an N4 session modification response message.

[0271] Step 1006: The UPF sends a QoS Configuration Request message to the terminal, which carries the QoS rule allocated to the terminal.

[0272] There is no limitation on whether the UPF and the access network device use a point-to-point interface or a service-based interface for message transmission.

[0273] Step 1007: After receiving the QoS rule assigned by the SMF, the terminal replies with a QoS ConfigurationAck message to the UPF.

[0274] 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.

[0275] Step 1009: SMF sends a session establishment response message to the terminal, indicating that the QoS control of the terminal has been completed.
