Description

Method, device, equipment and medium for processing PFD (pulse frequency division multiplexing) sending failure

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a medium for processing a PFD transmission failure.

Background

The Packet Flow Description (PFD) includes a detection rule for performing application detection, so that Packet flows of different applications in the network can be detected by the PFD, thereby providing differentiated services and application control for different applications, such as Packet interception and redirection, or performing different charging policy processing, such as Flow unification.

Among them, in the existing third Generation Partnership project (3 gpp) technical specification, PFDs are stored in a Unified Data Repository Function (UDR), and a Packet Flow Description Function (PFDF) is defined in a Network open Function (NEF) for acquisition and management of PFDs.

Specifically, the PFD processing flow defined in 3GPP is shown in fig. 1:

when an application initiates a PFD management request to the NEF, the NEF sends a PFD query request to the UDR through the PFDF contained in the NEF, and the UDR returns a PFD to respond. After the PFD is processed by the PFDF, the PFD is pushed to an SMF (Session Management Function) in a PUSH mode or the SMF uses a PULL mode to extract a file from the PFDF, and finally the SMF issues the processed PFD to a User Plane Function (UPF) to realize identification and detection of an application data packet stream of a data Plane.

As can be seen from fig. 1, when the SMF sends a failure response to the NEF, the subsequent processing flow is not given in the prior art. Therefore, in a scenario where multiple SMFs exist in an actual network, if the NEF fails to send the PFD, the consistency of the PFD is affected, and the practical value of application detection based on the PFD is reduced.

Therefore, how to fill the blank of the processing flow when the PFD fails to be sent in a plurality of SMF scenes, keep the consistency of the PFD, and improve the practical value of the application detection based on the PFD is a problem worthy of research.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The first embodiment is as follows:

in the prior art, in the process of sending the PFD to the SMF by the NEF, the PFD may be damaged, so that the PFD sending by the NEF fails, and therefore, for a scene with a plurality of SMFs, the PFD sending by the NEF fails, the consistency of the PFD is affected, and the practical value of application detection based on the PFD is reduced.

Therefore, in order to overcome the above technical problem, an embodiment of the present invention provides a method for processing a PFD transmission failure, as shown in fig. 2, the method includes the following steps:

step S201: if the NEF fails to send the PFD to the first SMF, the NEF sends a first message to other SMFs.

It should be noted that the first SMF is an SMF to which the NEF is to send the PFD, that is, a current SMF to which the NEF is to send the PFD. While the other SMFs are SMFs that have successfully received the PFD.

Since in the embodiment of the present invention, the first message is used to make the other SMFs perform rollback processing on the PFD that has been received by itself. In general, the rollback processing refers to an action of restoring a program or data to a last correct state when the program or data is processed in an error. Therefore, in the embodiment of the present invention, the rollback processing refers to recovering or updating the state of each SMF that has successfully received the PFD.

Specifically, restoring the state of each SMF that has successfully received the PFD means that each SMF that has successfully received the PFD deletes the PFD that has been received by itself, so that each SMF that has successfully received the PFD restores the state before the PFD is sent by the NEF, that is, the state before the PFD is not received. Therefore, each SMF which has successfully received the PFD deletes the PFD which has been received by itself, and the phase of the SMF is changed to be that the NEF never sends the PFD to all SMFs, so that the consistency of the PFD is maintained.

Updating the state of each SMF that has successfully received the PFD means that each SMF that has successfully received the PFD modifies the PFD that has received itself. Therefore, each SMF which has successfully received the PFD modifies the received PFD, so that the modified PFD of each SMF which has successfully received the PFD is consistent with the modified PFD sent in the later period of the NEF, thereby realizing the consistency of the PFD.

Therefore, in this embodiment of the present invention, the using of the first message to enable the other SMF to perform rollback processing on the PFD that has been received by itself includes:

So after the NEF sends the first message to other SMFs, the method further comprises the following steps S202 and S203 for other SMFs, namely:

step S202: the SMF receives a first message sent by the NEF.

Step S203: and rolling back the PFD received by the PFD according to the first message.

And the rollback processing of the PFD that has received itself according to the first message comprises:

deleting or modifying the PFD received by the PFD according to the first message.

Therefore, in the embodiment of the present invention, when the NEF sends the PFD to the multiple SMF scenes, if the NEF fails to send the PFD, the NEF sends the first message to the SMF that successfully receives the PFD, so that the SMF that successfully receives the PFD modifies or deletes the PFD that has been received by itself according to the first message, thereby filling up the blank of the PFD sending failure processing flow in the multiple SMF scenes in the prior art, and maintaining the consistency of the PFD, so as to improve the practical value of performing application detection based on the PFD.

Example two:

since the PFD is stored in the UDR, when an application initiates a PFD management request to the NEF, the NEF needs to push or issue the PFD sent by the UDR to the SMF again. As can be seen from the above embodiments, the first message is used to enable other SMFs to delete or modify the PFD that has been received by themselves. Thus, to keep the PFD consistent, the method further comprises:

and the NEF sends a second notification message to the UDR, wherein the second notification message is used for enabling the UDR to delete or modify the PFD stored by the NEF.

When the first message is used to enable each SMF that has successfully received the PFD to delete the PFD that has been received by itself, the second notification message that enables the UDR to delete the PFD that is stored by itself is sent to the UDR, so that the UDR can delete the PFD that is stored by itself, which is equivalent to that the PFD is never stored by the UDR, thereby achieving consistency of PFDs.

And when the first message is used for enabling each SMF which has successfully received the PFD to modify the PFD which has been received by the SMF, the second notification message which enables the UDR to modify the PFD which is stored by the UDR is sent to the UDR, so that the UDR can modify the PFD which is stored by the UDR, the modified PFD is sent to the ENF, and the NEF sends the modified PFD to each SMF. Therefore, each SMF which has successfully received the PFD can modify the PFD which has been received by itself according to the modified PFD, and the PFD in each SMF can be ensured to be consistent.

Thus, if the first message is for another SMF to modify the PFD that it has received, the method further comprises:

In the embodiment of the present invention, all SMFs to be transmitted with the PFD are collectively referred to as a second SMF.

Therefore, the second notification message is sent to the UDR through the NEF, so that the UDR can delete or modify the PFD stored in the UDR, and thus, with the above-described process of performing rollback processing on each SMF that has successfully received the PFD, a complete processing scheme when the PFD sending fails is formed, which has stronger implementability and improves the practical value of application detection based on the PFD.

In addition, when the NEF initiates a PFD management request, because a PFD call flow initiated by the management platform, or SCS, or AS, or other service platform is received, in order to further improve a complete processing scheme when the PFD fails to be sent, the method further includes:

and the NEF sends a third notification message of the PFD failure to a management platform or an SCS or an AS or other service platforms, so that the management platform or the SCS or the AS or other service platforms execute corresponding processing according to the third notification message.

Therefore, the third notification message of the PF is sent to the management platform or SCS (Services Capability Server) or AS (Application Server) or other service platform by the NEF, so that the management platform or SCS or AS or other service platform can execute corresponding processing, thereby further perfecting the above processing scheme based on "rollback + notification", making the scheme have stronger implementability, and further improving the practical value of Application detection based on the PFD.

It should be noted that, the SCS or AS described above is also defined in the technical specification of 3GPP, and therefore, in the embodiment of the present invention, it is not specifically described again.

Example three:

as can be seen from the PFD processing flow diagram defined in 3GPP shown in fig. 1, when a NEF sends a PFD to an SMF, PUSH mode active PUSH may be adopted, or PUSH mode passive delivery may also be adopted, so that determining that the NEF fails to send the PFD to the first SMF includes:

and if the NEF fails to push or send the PFD to the first SMF, determining that the NEF fails to send the PFD to the first SMF.

The reason why the NEF fails to push or issue the PFD to the first SMF may be that the PFD is damaged in the process of sending the PFD, and then the first SMF sends a failure response to the NEF.

If the PFD is not damaged during the process of transmitting the PFD, the first SMF transmits a success response to the NEF and locally installs or activates the PFD. However, if the PFD is not installed or activated locally due to other reasons, such as a problem with the PFD itself, determining that the NEF fails to send the PFD to the first SMF includes:

That is to say, in the embodiment of the present invention, the manner of determining that the NEF fails to send the PFD to the first SMF may be that the NEF pushes or issues the PFD to the first SMF in a failure manner, or that the NEF fails to install or activate the PFD on the first SMF. It is to be understood that, in the embodiment of the present invention, there is no particular limitation on the manner in which the NEF fails to send the PFD to the first SMF.

Example four:

as can be seen from the foregoing embodiments, the manner of determining that the NEF fails to send the PFD to the first SMF may be that the NEF pushes or issues the PFD failure to the first SMF, or that the NEF fails to install or activate the PFD on the first SMF. When the NEF fails to push or send the PFD to the first SMF, a failure response is sent to the NEF, and when the NEF fails to install or activate the PFD on the first SMF, a first notification message that the PFD fails to install or activate is reported to the NEF.

Therefore, in this embodiment of the present invention, the determining that the NEF fails to send the PFD to the first SMF includes:

That is, when the NEF receives the failure response sent by the first SMF or the first notification message that the PFD fails to be installed or activated reported by the first SMF, it directly determines that the PFD fails to be sent to the first SMF.

As can be seen from the above description, the reason why the PFD received by the SMF is unavailable may be that the PFD is damaged in the process of sending the PFD by the NEF, and the PFD itself has no problem, so when the NEF determines whether sending the PFD to the first SMF fails, the PFD may also be determined according to a failure attempt policy pre-configured by an operator. The failed attempt strategy is that for a certain task, the pointer indicates that the task fails only after the number of failures reaches a preset number or a threshold value. Therefore, in the embodiment of the present invention, the failure attempt policy refers to determining that the NEF fails to send the PFD to the first SMF when the number of times of the failure response sent by the first SMF or the first notification message reaches a preset number of times or a threshold value, that is, the number of times of the failure of the NEF to send the PFD to the first SMF reaches the preset number of times or the threshold value.

Therefore, in the embodiment of the present invention, the method further includes:

the determining that the NEF failed to send the PFD to the first SMF comprises:

That is, when the NEF determines that the PFD transmission to the first SMF fails according to the failure attempt policy pre-configured by the operator, the NEF updates the number of failure responses transmitted by the first SMF, and determines that the PFD transmission to the first SMF fails only if the updated number reaches the preset threshold.

Wherein, if the NEF receives the failure response or the number of times of receiving the first notification message does not reach a preset threshold, the method further comprises:

the NEF sends the PFD to the first SMF.

That is, if the preset threshold specified in the failure attempt policy configured by the operator in advance is 2, that is, the threshold of the number of failure responses or first notification messages set by the operator in advance is 2, and the first SMF is SMF1, when the NEF receives the failure response sent by SMF1 or the first notification message reported for the first time, the number of failure responses sent by SMF1 or the number of first notification messages reported is recorded as 1, and since 1 is smaller than 2, the NEF continues to send the PFD to SMF 1. If after receiving the PFD sent by the NEF, the SMF1 still sends a failure response or a first reported notification message to the NEF, the NEF updates the number of times of the failure response or the first reported notification message sent by the SMF1 to 2 times, and since the preset threshold value of the number of times of the failure response or the first notification message has been reached at this time, the NEF determines that the PFD sent to the SMF1 fails. However, if SMF1 sends a successful response to NEF after receiving the PFD sent by NEF, then NEF will send the PFD to a second SMF after SMF1 that is to be sent the PFD.

Therefore, as can be seen from the above description, when the NEF determines that the PFD transmission to the first SMF fails according to the failure attempt policy pre-configured by the operator, it is possible to avoid the erroneous judgment caused by the PFD damage during the PFD transmission.

In an actual push process, when a failure response sent by a first SMF to a NEF is sent, the failure response may carry specific error information, such as that a PFD is unavailable, or the PFD is damaged, and the like, so the NEF may send a first message to the first SMF according to the specific error information carried in the failure response, where the first message is a notify message, a remove message, a post message, a delete message, a put message, or a patch message, so that the first SMF performs corresponding processing according to the received message, and if the first message is a remove message, the SMF deletes the PFD that has been received by itself according to the remove message.

It should be noted that, the notify message, the remove message, the post message, the delete message, the put message, or the patch message is already defined in the technical specification of 3GPP, and therefore, in the embodiment of the present invention, a specific description thereof is not provided.

Example five:

when the NEF successfully sends the SMF, the NEF may receive a successful response sent by the SMF, and set the corresponding identification information of the sending result for each SMF that has successfully received the PFD according to the successful response, so on the basis of the foregoing embodiment, in the embodiment of the present invention, before the NEF sends the first message to another SMF, the method further includes:

acquiring identification information of a sending result set by the NEF aiming at the other SMFs, wherein the identification information records identification information of the other SMFs;

and determining the other SMFs according to the identification information.

The identification information of the SMF may be ID information of the SMF, but it is understood that the identification information of the SMF may also be other information related to the SMF, which is not specifically limited in this embodiment of the present invention.

Specifically, if SMF1 can successfully receive the PFD sent by NEF, a successful response is sent to NEF, then NEF sets the identification information of the transmission result of SMF1 to the identification information that SMF1 corresponds to the successful transmission, and if the identification information that SMF1 represents the successful transmission is represented by 1, the identification information of the transmission result set for SMF1 is SMF 1-1. If the SMF2 fails to receive the PFD sent by the NEF and sends a failure response to the NEF, the NEF sets the identification information of the sending result of the SMF2 to the identification information of the failed sending corresponding to the SMF2, and if the identification information of the successful sending is represented by 0, the identification information of the sending result set for the SMF1 is SMF 1-0. Then at this point NEF, when determining other SMFs, then determines SMF1 as the other SMF that successfully received the PFD.

Example six:

the NEF, SMF, and UPF described in the above embodiments are all network element nodes in the 5G system, where the NEF, SMF, and UPF network functions may refer to descriptions in the technical specification in 3gpp TS 23.501, and therefore are not described in detail in the embodiments of the present invention. Since the PFDF is defined in the NEF by the 3GPP and is used for acquiring and managing the PFD, a procedure of sending the PFD by the NEF may be specifically performed by the PFDF. Therefore, in the embodiment of the present invention, a PFD transmission failure processing flow will be described in detail with reference to fig. 3:

after the NEF (including the PFDF) initiates a management call to the PFD, it may send a PFD query request to the UDR through the PFDF included in the NEF, where it should be noted that the management call of the PFD initiated by the NEF is initiated by the management platform, SCS/AS, or other service platform to the NEF. And the UDR returns the PFD and an application identifier corresponding to the PFD, wherein the application identifier is used for indicating the PFD to execute a corresponding detection strategy. And the PFDF processes the PFD returned by the UDR after receiving the PFD, and sequentially pushes the PFD to the SMF by adopting a PUSH mode.

Specifically, as shown in fig. 3, the PFDF may send the PFD to SMF1 in PUSH mode or PULL mode, if the PFD is available, SMF1 returns a successful response to NEF, and the PFDF continues to send the PFD to SMF2 in PUSH mode or PULL mode, if the PFD is available, SMF2 returns a successful response to NEF. By analogy, the PFDF repeats the above steps and sends the PFD to the SMFn, and if the PFD is unavailable at this time, the SMFn returns a failure response to the NEF, and carries specific error information (e.g. file unavailable, etc.) in the response.

After receiving the SMFn failure response, the NEF may determine whether PFD transmission to the SMFn fails according to a failure attempt policy configured by an operator, that is, determine whether the number of times of the failure response transmitted by the SMFn reaches a preset failure number or a threshold value, if so, determine that PFD transmission to the SMFn fails, and transmit a remove message to SMF1, SMF2 … SMF (n-1), so that SMF1, SMF2 … SMF (n-1) deletes the received PFD.

Of course, it is understood that the NEF may also send any one of notify message, post message, delete message, put message, or patch message to the SMF1, SMF2 … SMF (n-1), so that the SMF1, SMF2 … SMF (n-1) performs the processing of the response according to the received message.

Meanwhile, after determining that the PFD transmission to the SMFn fails, the NEF may also send a second notification message to the UDR, so that the UDR deletes or modifies the PFD stored in itself. And sending a third notification message to the management platform, the SCS/AS or other service platforms, and feeding back the PFD sending failure to the management platform, the SCS/AS or other service platforms to complete the notification processing process of the PFD sending failure.

Therefore, in the embodiment of the present invention, when the NEF sends the PFD to the multiple SMF scenes, if the NEF fails to send the PFD to the current SMF, the NEF sends the first message to each SMF that has successfully received the PFD, so that the SMF can modify or delete the PFD that has been received by itself according to the first message, which not only fills up the blank of the PFD sending failure processing flow in the multiple SMF scenes in the prior art, but also can maintain the consistency of the PFD, and improve the practical value of the application detection based on the PFD.

In addition, the third notification message is sent to the UDR, the management platform, the SCS, the AS, or other service platforms through the NEF, so that the UDR, the management platform, the SCS, the AS, or other service platforms execute corresponding processing, and thus, a complete processing scheme for failure in sending the PFD is formed with the above process of modifying or deleting the SMF with the PFD that the SMF has received, which has stronger implementability and further improves the practical value of application detection based on the PFD.
