Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

Aiming at the problem that service interruption is easy to occur when a user selects URSP due to lack of processing related to a core network UPF in the existing URSP configuration and updating method, the invention provides a processing method of a routing strategy, and the URSP is updated by reporting an application detection report so as to ensure the service.

As shown in fig. 2, a processing method of a routing policy in an embodiment of the present invention is applied to a PCF, and includes:

step 201, receiving an application detection report reported by a user plane function UPF; wherein, the application detection report is reported when the UPF receives the uplink data stream;

step 202, providing a new routing policy for the terminal sending the uplink data stream according to the application detection report.

The processing method of the routing strategy in the embodiment of the invention is applied to PCF, and can provide the routing strategy for the terminal (namely user equipment) sending the uplink data stream according to the application detection report by receiving the application detection report reported by the UPF when the UPF receives the uplink data stream, namely the URSP is updated for the terminal, so that the user equipment can select more proper PDU for the uplink data stream based on the updated URSP, the capability of the UPF accords with the capability requirement of the data stream, the continuity of the service is ensured, and the user experience is improved.

Optionally, the uplink data stream satisfies a configured event trigger policy;

Here, the configuration of the event trigger policy in the UPF includes: at least one of user ID, data flow identification and event reporting triggering condition, wherein the event triggering strategy can be configured locally in advance by an administrator or configured for UPF by PCF to definitely apply the reporting timer of the detection report, thereby meeting the use requirement of a new routing strategy and avoiding resource waste. The user ID may be an identifier that may uniquely identify the UE, such as a network protocol address IP of the UE, a global positioning address GPSI of the UE, or an international mobile subscriber identity IMSI of the UE; the data flow identifier can be represented by various methods, for example, can be an IP five-tuple in a preset range, can also be a specific type or specific types of APP, and the like; the trigger condition is used for indicating whether the uplink data is reported when the condition is met or not met. Of course, if the UPF defaults to this trigger condition, the routing policy need not include the trigger condition.

In addition, it should be appreciated that the upstream in this embodiment refers to the data stream of the APP on the terminal, such as the data stream of a treasures.

Wherein, the step 201 includes:

and directly receiving an application detection report sent by the UPF.

Here, the application detection report sent by the UPF may be sent to the PCF via the SMF or may be sent directly to the PCF without the SMF forwarding. Therefore, the PCF can receive the application detection report sent by the UPF through the SMF, or directly receive the application detection report sent by the UPF.

Here, the application detection report causes the PCF to update the urs for the UE with the application detection report by carrying at least one of a user ID, a cause of the routing error, an application ID, and a data flow identification. Of course, the application detection report may use APP ID instead of the corresponding application ID (APP type) in addition to the above, and may also include content such as a urs reconfiguration instruction.

Furthermore, in this embodiment, the method further comprises:

and sending the event triggering strategy to the UPF.

In this way, the PCF can configure an event trigger policy for the UPF, so that the UPF can report an application detection report based on the event trigger policy, and update the routing policy in a targeted manner when the uplink data flow satisfies the event trigger policy.

The step of issuing the event trigger policy to the UPF includes:

and directly sending the event triggering strategy to the UPF.

Here, the PCF sends the event trigger policy to the UPF via the SMF, which may be implemented by a session management policy control creation service or a session management policy control update service. Specifically, in the PDU session establishment flow or the modification flow, or in the separate policy establishment update flow after the PDU flow is established, the PCF creates a service npcf_smpolicy control_create or a session management policy control update service npcf_smpolicy_update, etc., to issue to the SMF, and the SMF forwards the event trigger policy to the UPF.

In this embodiment, it should also be appreciated that the interaction between the UPF and the SMF and between the UPF and the PCF may be in the form of service invocation or messaging.

The message sending manner is implemented by adopting a fixed interface between two Network Functions (NF) in the point-to-point architecture, and the two Network Functions (NF) interact with each other through the message sending manner. The service call mode is that for the service architecture, NFs interact in the service call mode, similar to function call.

In summary, the processing method of the routing policy in the embodiment of the present invention is applied to PCF, and first receives an application detection report reported by UPF when receiving uplink data, and then provides a routing policy for a terminal sending the uplink data according to the application detection report, that is, updates the urs p for the terminal, so that the terminal can select a more appropriate PDU for the uplink data based on the updated urs p, so that the capability of the UPF accords with the capability requirement of the data flow, service continuity is ensured, and user experience is improved.

As shown in fig. 3, an embodiment of the present invention provides a method for processing a routing policy, which is applied to a user plane function UPF, and includes:

step 301, when an uplink data stream is received, reporting an application detection report to a policy control function PCF.

Through this step 301, the UPF will report an application detection report to the PCF when receiving the upstream, so that the PCF can provide a routing policy for the terminal sending the upstream based on the application detection report, that is, update the urs p for the terminal, so that the terminal can select a more appropriate PDU for the upstream based on the updated urs p, so that the capability of the UPF accords with the capability requirement of the data flow, ensure the continuity of the service, and improve the user experience.

Considering the need for a new routing policy, optionally, the upstream satisfies a configured event trigger policy;

In this way, the UPF detects the received uplink data stream by the configured event trigger strategy (comprising at least one of user ID, data stream identifier and event report trigger condition) to judge whether the user equipment uses improper PDU to send data because of error of the URSP configured on the user equipment; and then when the uplink data meets an event triggering strategy (namely, the URSP configured on the user equipment is determined to be wrong), reporting an application detection report to the PCF to clearly apply the reporting timer of the detection report, thereby meeting the use requirement for a new routing strategy and avoiding resource waste.

The user ID may be an identifier that may uniquely identify the UE, such as a network protocol address IP of the UE, a global positioning address GPSI of the UE, or an international mobile subscriber identity IMSI of the UE; the data flow identifier can be represented by various methods, for example, can be an IP five-tuple in a preset range, can also be a specific type or specific types of APP, and the like; the trigger condition is used for indicating whether the uplink data is reported when the condition is met or not met. Of course, if the UPF defaults to this trigger condition, the routing policy need not include the trigger condition.

and directly sending an application detection report to the PCF.

Here, the application detection report sent by the UPF may be sent to the PCF via the SMF or may be sent directly to the PCF without the SMF forwarding.

Optionally, the UPF sends the application detection report to the SMF by calling the SMF service or calling the UPF service, and then the SMF sends the application detection report to the PCF (specifically, the application detection report may be sent to the PCF by calling the service, for example, the SMF may call the Notify operation of the nsmf_eventExposure service of the SMF to implement sending the application detection report).

Wherein, before step 301, further comprises:

and acquiring a locally configured event trigger strategy.

Thus, the event trigger policy according to which the UPF detects the uplink data may be configured to the UPF by the PCF, or may be configured locally on the UPF.

It should also be appreciated that the PCF may send the event trigger policy to the UPF via the SMF (e.g., the PCF may forward the event trigger policy to the UPF by the SMF in a PDU session establishment procedure or a modification procedure, or in a separate policy establishment update after the PDU procedure is established, etc., by creating a service npcf_smplicycontrol_create or a session management policy control update service npcf_smplicycontrol_update, etc., to the SMF, or may send the event trigger policy directly to the UPF). Therefore, on the UPF side, the step of receiving the event trigger policy issued by the PCF includes:

and receiving an event triggering strategy directly sent by the PCF.

Here, for the event trigger policy configured by the PCF, the event trigger policy sent by the PCF via the SMF will be correspondingly received for the PCF configuration mode; or, receiving event trigger strategy sent by PCF directly.

In this embodiment, the interaction mode between the UPF and the SMF and the interaction mode between the UPF and the PCF may be a service calling mode or a message sending mode.

In summary, the processing method of the routing policy in the embodiment of the present invention is applied to UPF, and when an uplink data stream is received, an application detection report is reported to PCF, so that PCF can provide a routing policy for a terminal sending the uplink data stream based on the application detection report, that is, update the urs p for the terminal, so that the terminal can select a more appropriate PDU for the uplink data stream based on the updated urs p, so that the capability of UPF accords with the capability requirement of the data stream, service continuity is ensured, and user experience is improved.

As shown in fig. 4, the embodiment of the present invention further provides a processing method of a routing policy, which is applied to SMF, and includes:

Step 401, receiving an application detection report sent by a UPF, where the application detection report is reported when the UPF receives an uplink data stream;

step 402, sending the received application detection report to the PCF.

Here, the SMF forwards the received application detection report sent by the UPF to the PCF, so that after the PCF receives the application detection report, the PCF provides a routing policy for the terminal of the upstream based on the application detection report, that is, updates the urs p for the ue, so that the ue can select a more appropriate PDU for the upstream based on the updated urs p, so that the capability of the UPF accords with the capability requirement of the data flow, service continuity is ensured, and user experience is improved.

The uplink data flow meets a configured event triggering strategy;

In this way, the application detection report forwarded by the SMF is a UPF and is detected by the configured event trigger strategy (comprising at least one of user ID, data flow identification and event report trigger condition), and the uplink data is sent when the uplink data meets the event trigger strategy (namely, the URSP configured on the user equipment is determined to be wrong), so that the reporting time of the application detection report is clarified, the use requirement for a new routing strategy is met, and resource waste is avoided.

In addition, the event-triggered policy sent by the corresponding PCF to the UPF via the SMF, in this embodiment, the method further includes:

receiving an event triggering strategy sent by the PCF;

and sending the received event triggering strategy to the UPF.

In summary, the processing method of the routing policy in the embodiment of the present invention is applied to SMF, and first receives the application detection report sent by UPF, and then forwards the application detection report to PCF, so that PCF provides the routing policy for the terminal of the upstream based on the application detection report after receiving the application detection report, that is, updates the urs p for the ue, so that the ue can select a more appropriate PDU for the upstream based on the updated urs p, so that the capability of UPF accords with the capability requirement of the data flow, service continuity is ensured, and user experience is improved.
