Network for communication, that is, drone networking. Specifically, after the drone is connected to the Internet, it can obtain the unmanned aerial system (UAS) service. For example, the drone controller can remotely control the flight of the drone through the network, and the drone can transfer data through the network. The information is sent to the cloud, and the drone can also obtain timely obstacle avoidance assistance through the network. Among them, in order to control the flight of the drone through networking, the drone will request to establish a session on the user plane to connect with its controller. This session is called a command and control (command and control, C2) communication-related session, that is, a C2 communication session. , or may also be referred to as a C2 session, or may also be referred to as a C2 connection, or may also be referred to as a C2 communication-related session. In this application, for the convenience of description, C2 communication is used as an example for description in the following.

4. USS, UTM, UTM/USS: UAV networking requires the authentication and authorization of the UAV itself. If a session related to C2 communication needs to be established, the authentication and authorization of C2 communication is also required. These authentication authorizations need to be carried out in a third party. carried out in the entity. The third-party entity may include an unmanned aerial system service provider (UAS service supplier, USS) and/or an unmanned aerial system traffic management (UAS traffic management, UTM) network element.

It should be understood that a UAS service supplier (USS): An entity that supports the safe and efficient use of airspace by providing services to the operator or pilot of the drone to meet the operational requirements of the drone . USS can provide any subset of functionality to meet the provider's business objectives. It should be noted that this name is only for convenience to express its function, and should not constitute any limitation to this application, and this application does not exclude the possibility of adopting other names in subsequent standards.

It should also be understood that unmanned aerial system traffic management (UTM): a set of functions and services used to manage a range of automated equipment operations (e.g. drone certification, drone business authorization, drone policy management , airspace UAV flow control). It should be noted that this name is only for convenience to express its function, and should not constitute any limitation to this application, and this application does not exclude the possibility of adopting other names in subsequent standards.

In addition, the entities of the USS and the UTM may be one entity, may be in an inclusive relationship, or may be in a parallel relationship, which is not limited in this application. In the embodiments of this application, USS, UTM, and USS/UTM refer to the same entity, and its name may be a service entity or the like.

In order to facilitate understanding of the embodiments of the present application, by way of example, the following describes application scenarios of the embodiments of the present application in detail.

FIG. 2 shows a schematic diagram of an application scenario of an embodiment of the present application. As shown in Figure 2, the UAS of the unmanned aerial vehicle system can exchange information and communicate wirelessly with the UTM through the access network (radio access network, RAN) and core network (core network, CN). In addition, optionally, the UAVC or the UAV can exchange information with the access network and the core network; the UAVC can also exchange information with the UAV through the access network or the core network, and can also exchange information with the UAV through the UTM.

It should be understood that the UAVC and the UAV may be located in the same access network or core network, or may be located in different access networks or core networks, which is not limited in this embodiment of the present application.

For the convenience of description, in the subsequent application of this application, the terminal device is the UAV or the UAV controller, the session management network element in the core network is the SMF network element, and the network capability exposure network element in the core network is the NEF network element, which is example to illustrate. Further, the UAV is abbreviated as UAV, the UAV controller is abbreviated as UAVC, the SMF network element is abbreviated as SMF, and the NEF network element is referred to as NEF. That is, UAVs described later in this application can be replaced by drones, UAVCs can be replaced by drone controllers, SMFs can be replaced by session management network elements, and NEFs can be replaced by network capability exposure network elements.

When the application scenario of the UAV changes, the UAV controller may need to modify the control mode, and the quality of service (QoS) of the C2 communication flow under different control modes is different, so the control mode Updates are always accompanied by QoS updates for flows that are communicated by the C2. For example, more precise control is required during the landing of the drone, and higher QoS is required at this time, that is, the QoS update of the flow of C2 communication is required. However, for a C2 control mode, it may correspond to one or more QoS parameters. Therefore, when a C2 control mode corresponds to a QoS parameter that directly indicates the modification of the C2 control mode, that is, the update of the C2 control mode, The corresponding network element can map it to the update of the corresponding QoS parameter.

Generally, the QoS update process of the flow of C2 communication is as follows: first, the network on the UAVC side updates the QoS through the session modification process; then, after the QoS update is completed, the UAV is notified by other means such as C2 communication; The network then performs QoS update. In the above QoS update method, the network on the UAVC side performs the QoS update first, and the network on the UAV side performs the QoS update later. Therefore, in a short period of time, it may not be possible to ensure that the QoS updates on the UAV and UAVC sides are synchronized in time, that is, There may be a large QoS update delay from when the UAVC initiates the QoS update to the UAV completes the QoS update. In particular, when UAVC and UAV access different base stations, or base stations and core networks, or different public land mobile networks (PLMNs), the above-mentioned QoS update delay may further increase.

The present application proposes a method for QoS update of quality of service, which can reduce the QoS update delay from the UAVC side to the UAV side.

FIG. 3 shows a schematic flowchart of a method 300 for quality of service (QoS) update provided by the present application.

S301, the first network element receives first update information, where the first update information indicates the update of the QoS of the first session of the first terminal device, where the first session is used by the first terminal device to communicate with the second terminal device session.

In a possible implementation manner, the first terminal device and the second terminal device belong to the same UAS system. For example, when the first terminal device is a UAVC and the second terminal device is a UAV, the UAVC accesses the first 3GPP communication system, the UAV accesses the second 3GPP communication system, and the communication between the UAVC and the UAV requires a third-party entity, such as UTM.

It should be understood that, in this embodiment of the present application, the first network element belongs to a third-party entity, not a 3GPP system, and is independent of each PLMN, and provides services for the first and second terminal devices at the same time, and the access of the first and second terminal devices is different. PLMN. For example, the first network element may be a USS, a UTM network element, a network element formed by a USS and a UTM network element, or other possible network elements, the names of which are not limited in this application.

In a possible implementation manner, the first update information includes at least one of QoS parameters and QoS rules of the first session of the first terminal device. Therefore, the first network element can determine the opposite end that needs to be updated, that is, the related information of the QoS flow of the second session on the side of the second terminal device.

It should be understood that QoS parameters refer to QoS requirements associated with QoS flows, including but not limited to QoS parameters (QoS parameters), QoS characteristics (QoS characteristics), and the like. QoS parameters may also be referred to as QoS Flow level QoS parameters, QoS reference, QoS flow descriptions, QoS Information, and the like. Specifically, the QoS parameters may include one or more of the following: 5QI (5G QoS Identifier, 5G QoS identifier), ARP (allocation and retention priority, allocation and retention priority), RQA (Reflective QoS Attribute, reflective QoS attribute) , Notification control, Flow Bit Rates, Aggregate Bit Rates, Default values, Maximum Packet Loss Rate, Resource Type , Priority Level, Packet Delay Budget, Packet Error Rate, Average Window, Maximum Data Burst Volume, etc.

It should also be understood that QoS rules are used to classify and mark user plane traffic (UL User plane traffic), that is, based on QoS rules, traffic (traffic) can be associated with QoS Flows (QoS Flows), which can also be called Flow Description (Flow description) )Wait. Specifically, the QoS rule may include one or more of the following: QoS flow identifier, source IP address, destination IP address, protocol identifier, source port, destination port, service type, flow type, flow label, security parameter Index, packet filter direction, source MAC address, destination MAC address, ether type, precedence value, etc.

This application does not limit the specific names and contents of QoS parameters and QoS rules.

It should be understood that the first update information may be composed of one or more information elements, and one or more information elements constituting the first update information may be existing or new. It should also be understood that the first update information may be a first update message, or the first update information may also be included in a certain message, such as a session modification request message. This application does not limit this.

In this embodiment of the present application, there are two optional specific implementation manners for the first network element to receive the first update information:

Manner 1: The first network element receives the first update information from the first terminal device, that is, the first update information is generated in the first terminal device. Therefore, the first network element may receive the first update information from the first terminal device through one or more other network elements, wherein the first update information may be included in multiple messages, for example, the first terminal device includes the first update information The first update message is sent to the intermediate network element, and the intermediate network element includes the first update information in the second update message and sends it to the first network element, which is not limited in this application.

Optionally, for the first manner above, the first update information is mobile mode update information, that is, the mobile mode update information is generated in the first terminal device. It should be understood that the mobile mode update information may also be referred to as control mode update information of C2 communication, the mobile mode update information requesting authorization to update the mobile mode of the first terminal device or the second terminal device. It should also be understood that the update of the mobility mode needs to be implemented through the update of a series of information or parameters, including the update of the QoS parameters of the session. Therefore, in the relevant network element, it may be the first network element or other network elements. The mapping relationship between the mobility mode and the QoS parameter is stored, and the first network element can determine the QoS parameter that needs to be updated after receiving the first update information.

Manner 2: The first network element receives the first update information from the second network element, that is, the first update information is generated in the second network element. Therefore, the first network element may receive the first update information sent by the second network element, or the first network element may receive the first update information from the second network element through other network elements, which is not limited in this application.

It should be understood that the second network element is a network element in the first communication system accessed by the first terminal device, for example, a session management network element, such as SMF; or, for example, a network capability exposure network element, such as NEF. It should also be understood that when the first network element receives the first update information from the second network element through other network elements and the second network element is an SMF, the first network element may receive the first update information from the SMF through the NEF.

Optionally, for the second way, before the first network element receives the first update information from the second network element, the method may further include step S1:

S1, the first terminal device sends a session modification request message to the second network element, the session modification request message requests the update of the QoS of the first session of the first terminal device, and accordingly, the second network element receives the message from the first terminal device. Session modification request message.

Specifically, after the second network element receives the session modification request message from the first terminal device, the second network element will determine the first update information according to the session modification request, and send the first update information to the first network element .

In this embodiment of the present application, for the first update information to indicate the update of the QoS of the first session of the first terminal device, there are two optional specific indication situations:

Scenario 1: The first update information notifies the first terminal device that the QoS of the first session of the first terminal device is updated. Optionally, the first update information indicates that the QoS of the first session of the first terminal device is about to be updated or has been updated. In this case, the first update information may be the first update notification information.

Scenario 2: The first update information requests to authorize the update of the QoS of the first session of the first terminal device. At this time, the first update information may be the first update authorization request information.

S302: The first network element sends second update information according to the first update information, where the second update information indicates the update of the QoS of the second session of the second terminal device, where the second session is used by the second terminal device to communicate with A session in which the first terminal device communicates.

Specifically, in this embodiment of the present application, the first network element sends the second update information to the third network element according to the first update information. Optionally, the third network element is a network element in the second communication system accessed by the second terminal device, for example, a session management network element in the second communication system, such as an SMF; another example is a network capability exposure network element, For example, NEF, etc.; or other network elements, which are not limited in this application.

In a possible implementation manner, the second update information is second update request information, that is, the second update request information requests to update the QoS of the second session of the second terminal device.

Therefore, in the present application, after the first network element receives the relevant information about the QoS update of the first session on the first terminal device side, the first network element instructs the second terminal device side to update the QoS of the second session , so that the QoS updates of the sessions on both sides of the first terminal device and the second terminal device can be synchronized, and the QoS update delay from the first terminal device end to the second terminal device end can be reduced.

Optionally, for the first situation and the second situation in the above step 301, the method 300 may further include multiple steps respectively.

For the first case, that is, when the first update information notifies the first terminal device that the QoS of the first session of the first session is updated, the method 300 may include S303-S304.

S303: The first network element sends first update subscription request information to the second network element, where the first update subscription request information subscribes to the update of the QoS of the first session of the first terminal device.

Specifically, in this embodiment of the present application, the first network element may directly send the first update subscription request information to the second network element, or the first network element may also send the first update to the second network element through other network elements Subscription request information. This application does not limit this.

In a possible implementation manner, the first update subscription request information includes QoS flow description information, where the QoS flow description information indicates packet filtering information of the QoS flow. It should be understood that the packet filtering information of the QoS flow refers to the address information of the origin and destination of the QoS flow, and the like.

In another possible implementation manner, the first update subscription request information includes information of the first terminal device, for example, address information and/or identification information of the first terminal device.

S304: The first network element receives first update subscription response information from the second network element, where the first update subscription response information indicates that the update subscription of the QoS of the first session of the first terminal device is successful.

Specifically, in the embodiment of the present application, when the first network element receives the first update subscription response information from the second network element, it can be understood that the first update subscription response information is generated in the second network element. Optionally, the first network element may directly receive the first update subscription response information sent by the second network element, or the first network element may also receive the first update subscription response information sent by the second network element through other network elements.

Therefore, the first network element subscribes to the update of the QoS of the first session of the first terminal device, that is, the update of the QoS of the first session does not need to be authorized by the first network element, and the first terminal device can further independently decide whether to Updating the QoS at both ends increases the initiative of the terminal equipment, thereby facilitating the synchronization of QoS updates on the first terminal equipment and the second terminal equipment, and reducing the end-to-end QoS update delay from the first terminal equipment to the second terminal equipment.

For the second situation, that is, when the first update information requests to authorize the update of the QoS of the first session of the first terminal device, the method 300 may further include steps S305-S306.

S305: The first network element determines, according to the first update information, to allow the update of the QoS of the first session of the first terminal device.

Specifically, in this embodiment of the present application, after receiving the first update information, the first network element will, according to the first update information, determine whether to allow the update of the QoS of the first session of the first terminal device.

In a possible implementation manner, the first network element stores the mapping relationship between the mobility mode and the QoS, and when the first update information is the mobility mode update information: the first network element can determine whether to allow the mobility according to relevant network policies, etc. Mode update, so as to further judge whether to allow the update of the QoS of the first session of the first terminal device according to the mapping relationship; or, the first network element first maps the mobility mode to QoS, and then judges whether to allow the first session of the first terminal device. QoS updates.

S306: The first network element sends first update response information, where the first update response information indicates that the update of the QoS of the first session of the first terminal device is allowed.

Specifically, in this embodiment of the present application, after the first network element determines whether to allow the QoS update of the first session of the first terminal device, the first network element will send the first network element to the second network element or the first terminal device. Update response information, where the first update response information indicates whether to allow the update of the QoS of the first session of the first terminal device.

Therefore, the method for obtaining the authorization of the first network element is required to update the QoS of the first session of the first terminal device, that is, whether the QoS of the first terminal device can be updated is determined by the first network element. Relevant regulations, policies, etc. are determined, thereby avoiding potential public safety hazards caused by the first terminal device side deciding to allow the QoS update of the first session, and improving the flexibility of the first network element. Thereby, the realization of synchronization of QoS update on the side of the first terminal device and the second terminal device is further ensured, and the end-to-end QoS update delay from the first terminal device to the second terminal device is reduced.

It should be understood that the QoS update of the relevant session mentioned in this application specifically refers to the update of the QoS requirements (QoS requirements) of a specific QoS flow (QoS Flow) in the relevant session, and a session includes one or more QoS flows.

It should also be understood that the terminal device for performing the above method may also be a chip or a chip system provided in the terminal device; for the first network element performing the above method, it may also be a chip provided in the first network element. or a chip system; for the second network element performing the above method, it may also be a chip or a chip system arranged in the second network element; for the third network element performing the above method, it may also be a chip or a chip system arranged in the third network element A chip or a chip system in the cell; this is not limited in this embodiment of the present application.

It should be understood that, in the above steps S301-S306, (1) the first network element may be a USS, a UTM, or a network element formed by USS and UTM network elements, etc.; (2) the second network element is The network element in the first communication system accessed by the first terminal device is, for example, a session management network element, such as SMF, and, for example, is a network capability opening network element, such as NEF, etc.; (3) a third network element Accessing a network element in the second communication system for the second terminal device, for example, a session management network element, such as SMF, or, for example, a network capability opening network element, such as NEF, etc.; (4) the first terminal device . The second terminal device may be UAVC or UAV. Optionally, the first network element and the first terminal device, the second network element or the third network element can exchange information through other network elements. For example, the first network element and the second network element can be opened through network capabilities. Network elements (such as NEFs) exchange information. This application does not limit this.

In order to facilitate understanding of a QoS update method provided by this application, the following, as an example and not a limitation, take the first network element as the UTM, the second network element as the first SMF, the third network element as the second SMF, and the first network element as the UTM. The terminal device is a UAVC, the second terminal device is a UAV, and the information exchange between the first network element and the second network element is performed through NEF as an example, with reference to the specific example methods shown in FIGS. Scenario one (S301-S302, S303-S304) and scenario two (S301-S302, S305-S306) are described in detail.

It should be noted that some of the steps mentioned below are the same as the above-mentioned method 300 , and the relevant details will not be repeated here. For the specific process, refer to the relevant steps of the method 300 .

Fig. 4 shows a schematic flow chart of a specific example method 400 of a method for quality of service QoS update provided by the present application.

S401, the UTM sends first update subscription request information to the NEF, the first update subscription request information subscribes to the update of the QoS of the first session of the UAVC, and correspondingly, the NEF receives the first update subscription request information sent by the UTM.

In a possible implementation manner, the service operation (Nnef_EventExposure_Subscribe operation) provided by the UTM invoking the NEF includes the first update subscription request information, or other messages include the first update subscription request information, which is not limited in this application.

S402, the NEF sends the first update subscription request information to the first SMF, and correspondingly, the first SMF receives the first update subscription request information sent by the NEF.

For the specific process of the above steps S401 and S402, reference may be made to S303 in the method 300.

S403: The first SMF sends first update subscription response information to the NEF, where the first update subscription response information indicates that the update subscription of the QoS of the first session of the first terminal device is successful. Correspondingly, the NEF receives the first update subscription sent by the first SMF. Update subscription response information.

S404, the NEF sends the first update subscription response information to the UTM, and accordingly, the UTM receives the first update subscription response information.

For the specific processes of the above steps S403 and S404 , reference may be made to S304 in the method 300 .

S405, the UAVC sends a session modification request message to the first SMF, where the session modification request message requests to update the QoS of the first session of the UAVC. Correspondingly, the first SMF receives the session modification request message sent by the UAVC.

In a possible implementation manner, the session modification request message includes first update information, and in this case, the first update information is mobile mode update information, or may also be called control mode update information of C2 communication.

S406, the first SMF sends the first update information to the NEF, where the first update information notifies that the QoS of the first session of the UAVC is updated, and accordingly, the NEF receives the first update information sent by the first SMF.

Specifically, the first SMF determines whether the subscribed QoS update matches the requested QoS update according to the received first update subscription request information and the session modification request message, that is, determines whether the requested QoS update is subscribed, and After it is determined that the requested QoS update is subscribed, the first update information is sent to the NEF. For example, the session modification request message includes a first QoS rule, and the first update subscription request message includes a second QoS rule. If the first QoS rule matches the second QoS rule, it is determined whether the requested QoS update is subscribed. Here, the matching of the first QoS rule and the second QoS rule refers to that the included contents are partially or completely the same, for example, the source and destination Internet Protocol addresses (Internet protocol addresses, IP addresses) are the same. This application does not limit the specific manner of how to determine whether the subscribed QoS update matches the requested QoS update.

In a possible implementation manner, when the session modification request message in S405 includes the mobile mode update information, the first SMF can determine the QoS that needs to be updated according to the mapping relationship between the mobile mode and the QoS, and pass the first update information. to indicate the update of the QoS of the first session of the UAVC.
