The air, space and ground integrated network is the key technology for future 6G networks, and the deployment of network elements to satellites is a key feature. In the terrestrial network scenario, both the network and the terminal are on the ground, and the terminal position is determined using two-dimensional coordinates, which is relatively simple.

Figure 1 shows a schematic diagram of the on-board network and terminal scenario of the future satellite network. As shown in Figure 1, the terminal and the network can be connected through the mobile network. Among them, the terminal can be on the ground or in high, medium or low orbit, and the terminal can be in the form of a satellite, satellite communication module or other aircraft.

In view of the problems existing in related technologies, the present disclosure proposes a session policy processing method, which is applied to the session functional unit and the policy functional unit. The session functional unit and the policy functional unit are deployed in satellites in high, medium and low orbits. Figure 2 shows a flow chart of a session policy processing method. As shown in Figure 2, the session policy processing method at least includes the following steps:

In addition, the session function unit can also update and control the session policy based on the judgment of the update trigger conditions, and adjust the session policy in real time, thereby achieving control of the session quality of the user device under different circumstances and optimizing the user experience. experience, improved to a certain extent User return rate.

Each step of the session policy processing method is described in detail below.

In step S210, when the user equipment initiates a session request, the session function unit reports policy establishment information and sends a session policy establishment request to the policy function unit.

In an exemplary embodiment of the present disclosure, the session functional unit is deployed in the satellite's high, medium and low orbits, can interact with the policy functional unit, and perform session policy establishment, session policy change, session policy termination, etc.

Specifically, the session function unit can obtain policy establishment information such as user subscription information, spatial location information, and orbit parameter information to determine whether to trigger a session policy change.

In addition, the session functional unit can also perform according to the requirements of the policy functional unit to adjust the quality of user sessions. Generally, the adjusted quality of user sessions can include QoS (Quality of Service, Quality of Service) and maximum session rate. Not only that, you can also adjust the policy change conditions, that is, update the trigger conditions.

The policy functional unit is also deployed on satellites in high, medium and low orbits and can interact with the session functional unit to implement session policy establishment, session policy change and session policy termination.

Specifically, the policy function unit can obtain user subscription information, formulate a session control policy based on user subscription information, spatial location information, orbit parameter information and other policy establishment information, and issue the corresponding session policy to the session function unit.

In the star network scenario, the establishment of session policy is completed by the interaction between the session functional unit and the policy functional unit, and is used when the user establishes a session.

The session functional unit reports network and user information, session parameters, and spatial location orbit parameters of users and session units. The policy functional unit allocates corresponding maximum session rates and QoS to users based on the obtained user subscription information, etc., as well as session policy updates. Trigger conditions, such as changes in spatial location, etc.

When the user equipment initiates a session request, the user can initiate an access request to the session functional unit.

Further, the session function unit requests the policy function unit to establish session policy control and provides policy establishment information.

In an optional embodiment, the policy establishment information includes: user subscription information, spatial location information, and orbit parameter information.

Specifically, user subscription information may include network ID (Identity document, identification), user ID, session ID, session type, session grouping, etc.; spatial location information may include user location, session functional unit spatial location, etc.; orbit parameter information may include User track parameters and session functional unit track parameters, etc.

In step S220, the policy function unit responds to the session policy establishment request, determines the session policy and update trigger conditions corresponding to the policy establishment information, and sends the session policy and update trigger conditions to the session function unit.

In an exemplary embodiment of the present disclosure, when the policy function unit receives the session policy establishment request sent by the session function unit, it may respond to the policy establishment request, determine the session policy corresponding to the policy establishment information, and update the trigger condition.

In an optional embodiment, the session policy and the update triggering condition corresponding to the policy establishment information are obtained from the user management unit corresponding to the policy functional unit.

The policy function unit obtains the session policy configured by the user's subscription information from the user management unit, and responds by issuing a policy control response, providing the user with session maximum rate, QoS, etc., and issuing session update trigger conditions, that is, update trigger conditions.

Among them, the update triggering conditions may include changes in contract conditions and changes in spatial location. Specifically, changes in contract conditions may include changes in session maximum rate, session QoS changes, etc.; changes in spatial location will lead to changes in session conditions, such as changes in the user's spatial location, updates to the user's track parameters, changes in the location and track of the relative session functional unit, etc. .

It is worth noting that the update triggering condition may be one or more, which is not specifically limited in this exemplary embodiment.

After the session policy and update triggering conditions are determined, the session policy and update triggering conditions can be sent to the session functional unit.

In step S230, the session functional unit stores and implements the session policy to provide user equipment with services corresponding to the session policy.

In an exemplary embodiment of the present disclosure, after the session function unit receives the session policy and the update trigger condition issued by the policy function unit, the session function unit stores and implements the session policy, and provides the user device with the corresponding session maximum rate. and QoS services.

Therefore, the session policy is established by the session functional unit reporting network and user information, session parameters, and the spatial location and orbital parameters of the session functional unit and the user. Further, based on the obtained user subscription information, the policy function unit allocates the corresponding maximum session rate and QoS to the user, as well as trigger conditions for session policy update, such as track relative movement trigger, etc.

After establishing a session policy, you can also control changes to the session policy when the update triggering conditions are met.

In an optional embodiment, Figure 3 shows a schematic flowchart of a method for changing session policies and updating trigger conditions. As shown in Figure 3, the method may at least include the following steps: In step S310, when the session function When the unit meets the update trigger condition, it sends a change session request to the policy function unit, and the change session request includes the changed policy establishment information.

In the star network scenario, the session rate change is completed interactively by the session functional unit and the policy functional unit, and is used when the update triggering conditions of the session policy are met.

When the session functional unit triggers a policy control change request, the policy functional unit can update the new session policy and update the triggering conditions.

When the session functional unit meets the update triggering conditions of policy control, for example, the subscription session changes, it can request the policy functional unit to change the session policy, and carry the obtained changed policy establishment information, such as changed user subscription information, etc. Among them, when the user track position, session unit track position, relative position, etc. are changed, the changed track parameter information can be carried.

In step S320, the policy function unit obtains the current resource information, and updates the session policy and update triggering conditions according to the session change request and the current resource information.

When the policy functional unit receives a change session request from the session functional unit, the change session request may be processed.

Further, the current resource information at this time can be obtained, such as whether the current resource is occupied or how much is occupied, etc.

Furthermore, the policy function unit can comprehensively analyze the current resource information and change session requests to update the session policy and update trigger conditions.

In step S330, the policy function unit delivers the updated session policy and the update trigger condition to the session function unit, so that the session function unit stores and implements the updated session policy and update trigger condition.

After the policy function unit updates the session policy and updates the trigger conditions, it can deliver the updated session policy and update trigger conditions to the session function unit, including the authorized session maximum rate and QoS, as well as the update trigger conditions.

The session functional unit can store and update session policies and update trigger conditions in real time, and provide users with corresponding session maximum rate and QoS session services.

In an optional embodiment, Figure 4 shows a schematic flowchart of another method of changing session policies and updating trigger conditions. As shown in Figure 4, the method may at least include the following steps: In step S410, the policy function The unit updates the configuration of the session policy and update trigger conditions, and sends the updated session policy and update trigger conditions to the session function unit.

The policy functional unit can also trigger change requests due to changes in user session policies.

When the maximum session rate of users on the same track as the session functional unit increases or other changes occur, the policy functional unit can configure a new session policy. The policy functional unit issues a new session policy and updates the trigger conditions to the session functional unit through a policy change request.

In step S420, the session functional unit responds to the policy functional unit and stores and implements the updated session policy and the updated trigger condition.

The session functional unit responds to the policy functional unit, and stores and executes the updated session policy and updated trigger conditions to provide users with new session policies, such as increasing the maximum session policy for users on the same track, etc.

In this exemplary embodiment, when the policy function unit triggers a session policy change, the session policy can be adjusted, thereby achieving session quality control under different circumstances, improving the session policy change solution, and ensuring user equipment from two aspects session quality and user experience.

Therefore, the change of the session policy may be the session functional unit or the policy functional unit triggering the control change condition to update the new session policy and update the triggering condition.

After establishing or updating a session policy, you can also terminate the corresponding session policy.

Policy termination includes two types: policy control termination initiated by the session functional unit and policy control termination initiated by the policy functional unit.

In an optional embodiment, Figure 5 shows a schematic flowchart of a method for terminating a session policy. As shown in Figure 5, the method may at least include the following steps: In step S510, when the session function unit terminates the session policy When, a policy termination request is sent to the policy functional unit.

The session functional unit can terminate the session policy when the user's subscription changes, or the session functional unit itself moves. At this time, the policy functional unit and the session functional unit need to delete the user-related session policy and control information.

The session functional unit decides to terminate the provision of session policies due to user subscription changes or when it moves. Therefore, it can initiate a policy termination request. The policy termination request may include user ID and other information.

In step S520, the policy function unit responds to the policy termination request and deletes the policy control information corresponding to the session policy.

The policy functional unit may respond to the policy termination request sent by the session functional unit and provide the user's policy control information corresponding to the session policy. The policy control information may include information on the method of formulating the session policy.

In step S530, the session functional unit deletes the session policy and updates the trigger condition.

In addition, the session functional unit will also delete the session policy that has been established or updated, and the corresponding update trigger conditions.

In this exemplary embodiment, the session function unit can actively initiate the termination of the session policy, providing a way to terminate the session policy, which facilitates real-time adjustment of the status of the session policy according to the actual situation and optimizes the user's service experience.

In an optional embodiment, Figure 6 shows a schematic flowchart of another method for terminating a session policy. As shown in Figure 6, the method may at least include the following steps: In step S610, when the policy function unit terminates the session strategy, Sends a policy termination request to the session functional unit.

When the policy function unit initiates policy control termination, the policy function unit can terminate the session policy of the session function unit, so that the policy function unit and the session function unit delete user-related session policies and control information.

When the policy function unit knows that the user track has changed and requires timely termination of the user's session, the policy function unit can send a policy termination request as needed. The policy termination request may include user ID, etc.

In step S620, the session functional unit responds to the policy termination request, deletes the session policy and updates the trigger condition.
