Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the application and use process, under the condition of mobile edge calculation, a UPF and a session anchor point thereof sink and are far away from a control plane which is centrally deployed, an AF adjusts a strategy and issues the strategy to the UPF, and translation of control logic needs to be performed between intermediate NF (Network Function) s.
In one embodiment, in a deployment mode of mobile edge computing, when both an application server and a session anchor point are deployed far away from a control plane, the application server directly performs policy control on the session anchor point.
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for controlling a session anchor according to an embodiment of the present invention, where the method includes:
s100, receiving a strategy which is directly sent by an application server through a capability open interface of the session anchor point and used for controlling the session anchor point.
Specifically, in the AF using process, the AF detects that the current anchor point cannot meet the service requirement, and triggers policy updating, for example, the anchor point needs to be replaced; the AF initiates an update request to the session anchor, and the AF issues a control policy to the session anchor through the capability open interface of the session anchor, for example, the request carries the deployment condition of the application server.
Further, the application server AF directly issues policy control through an N6 port using an open interface of capabilities provided by the session anchor point. Therefore, the path is effectively shortened, the mutual translation process of the control strategy by the intermediate network element is avoided, and the logic is simplified.
S200, identifying the strategy, and directly implementing the strategy or forwarding the strategy according to the strategy.
Specifically, after receiving the control information from the application server, the session anchor identifies and executes a policy, and according to the different policies, the UPF decision is executed at the session anchor or reported to the SMF for further decision. For example, the policy such as QoS may be enforced by the session anchor, but for example, the policy may need to be reported to the SMF for decision enforcement. Specifically, for example, after the AF informs the deployment condition of the application of the session anchor, the AF is required to reselect a server, the session anchor identifies the policy and informs the SMF, and after the SMF receives the policy, taking the replacement anchor as an example, the SMF determines that the server of the AF is in the LDN (LiuLin intelligent Network distribution technology, LiuLin Delivery Network, LDN technology for short), and selects a new session anchor. At this time, a process of establishing an ULCL (Uplink classifier) is initiated, and a flow of inserting the ULCL is executed.
In one embodiment, the step of receiving the policy for controlling the session anchor directly sent by the application server through the capability open interface of the session anchor further includes:
and acquiring the successful attachment of the user terminal, and establishing the connection between the user terminal and an application server of a core network.
Specifically, the successful attachment of the user terminal registered in the core network is acquired, and the connection between the user terminal and the application server of the core network is established.
Further, in the initial attach process of the ue registered in the core network, a session anchor point is selected for the ue by an Access and mobility management Function (AMF) core network according to a policy, and the ue is successfully attached to the session anchor point to establish a connection between the ue and an application server of the core network.
Under the deployment mode of mobile edge computing, an application server deployed far away from a control surface can directly control a session anchor point by issuing a strategy through a capability open interface provided by the session anchor point.
Referring to fig. 3 and 4, fig. 3 and 4 are a reference block diagram and a timing flow diagram of a session anchor control method in a session anchor situation according to an embodiment of the present invention, and referring to fig. 3, the session anchor of the user plane function UPF provides an ability open interface for an application server AF to use for issuing a policy. As shown in fig. 4, the whole process includes:
step 1) the User terminal UE (i.e. User Equipment) successfully attaches to a session anchor point PSA.
The PSA, i.e., PDU Session Anchor, PDU, Protocol Data Unit, refers to a Protocol Data Unit, and is a UPF, terminating N6 interface according to the Protocol specification of 3GPP 23.502, please refer to fig. 3.
And step 2) after the user terminal UE is attached to the PSA, the application server AF performs data interaction with the user plane function and the session anchor Point (PSA).
And 3) in the using process of the AF, detecting and finding that the current anchor point can not meet the service requirement, and triggering strategy updating. For example, the user terminal needs to be accessed nearby when the position is changed; or QoS does not meet the service requirements, etc., resulting in the need to replace the session anchor.
The strategy described in this step can be of many kinds, not limited to replacing anchor points, but also can be a strategy directly executed by the PSA.
And 4) the AF issues a strategy to the session anchor point through the capability open interface of the session anchor point, and the AF initiates an updating request to the session anchor point, wherein the updating request carries the deployment condition of the application server, for example.
And 5: after receiving the policy request of the AF, the session anchor identifies the policy, and according to the difference of the policies, the UPF may locally execute the policy, or send the policy to the session management function SMF, which is locally executed by the UPF in this example.
Step 6: after receiving the strategy, the UPF session anchor point executes the strategy and implements the strategy in the subsequent packet forwarding process.
In another embodiment, please refer to fig. 5 and 6, and fig. 5 and 6 are a reference block diagram and a timing flowchart of a control method of a session anchor point in the case of multiple session anchors according to an embodiment of the present invention. Under the deployment mode of mobile edge computing, under the scene of a multi-session anchor point, under the condition that an application server and the session anchor point are both deployed far away from a control surface, the application server directly carries out policy control on the session anchor point. In a multi-session anchor Point scenario, an ULCL (Uplink classifier) or a BP (branch Point) provides a capability interface to support policy control, so that a session anchor Point can report a policy to be executed by the ULCL or the BP.
In the context of the ULCL, the method of this embodiment requires that the session anchor point can directly provide an ability open interface to the application server, and the interface between the session anchor point and the ULCL can support the ability control, specifically, an interface that requires the interaction of the support ability between the session anchor point and the ULCL, and the session anchor point can report the policy issued by the application server to the ULCL, and the ULCL implements the policy.
In a ULCL scenario, traffic on the current AF server (LDN) needs to be directed to another AF server due to policy adjustments during AF usage. And the current AF informs that the re-shunting is needed through the capability open interface of the session anchor point, and after recognizing the strategy, the session anchor point forwards the strategy to the corresponding ULCL to execute the strategy. For example: in terms of the operation policy of the AF, the AF informs, through the session anchor point, that part of the original LDN-based traffic of the ULCL needs to go to the Internet again, and the specific process is as shown in fig. 4, and includes the following steps:
according to the protocol specification of 3GPP 23.501, an uplink classifier ULCL manages a plurality of session anchors, the session anchors share one IP, and a user terminal does not sense the IP; the BP manages a plurality of session anchor points, and each session anchor point is sensed by the user terminal and corresponds to one IPV 6.
Step 2, the application server AF and the session anchor point 1 carry out data interaction;
and 3, in the using process of the AF, the AF detects that the current anchor point can not meet the service requirement, for example, due to the operation strategy of the AF, part of the service which originally walks the LDN needs to walk the Internet again.
The policy here is merely an example, and is not limited to this policy, and any policy that requires ULCL or BP enforcement is applicable.
Step 4, the AF issues a policy, such as a service offloading policy in this embodiment, to the session anchor point 1 of the UPF through the capability open interface of the session anchor point;
and step 5, after receiving the policy request of the AF, the session anchor point 1 further forwards the policy request to the uplink classifier ULCL or BP to which the request belongs.
And 6, after receiving the policy request, the ULCL or BP executes the policy and implements the policy in the subsequent packet forwarding process. In this embodiment, the original LDN flow is led to the Internet.
In one embodiment, the step of receiving the policy for controlling the session anchor directly sent by the application server through the capability open interface of the session anchor further includes:
and defining a capability open interface between the session anchor point and the application server, so that the application server directly issues a control strategy to the session anchor point through the capability open interface.
Specifically, the session anchor point can directly provide an ability open interface for the application server, and an interface between the session anchor point and the application server needs to be defined first, and the interface can be defined according to actual needs. Further, the session anchor provides an ability-opening interface to the application server, and the specific implementation is to agree a set of message structures between the session anchor and the application server, and agree what the session anchor can do with a certain interface, as shown in fig. 3, for example, by agreeing a set of message structures between the application server and the session anchor, the session anchor can directly receive the policy issued by the application server through the N6 interface, and when the session anchor receives the policy issued by the application server AF through the N6 interface, the session anchor performs corresponding processing on the received policy.
In one embodiment, the step of forwarding the policy comprises:
forwarding the policy to a session management function, and implementing the policy through the session management function;
or forwarding the strategy to an uplink classifier, and implementing the strategy through the uplink classifier.
Specifically, in the case of one session anchor point, the UPF may locally execute the policy, or may send the policy to the session management function SMF, and execute the policy by the SMF; and under the condition of a plurality of session anchors, the AF issues a strategy to the session anchor of the UPF through the capability open interface of the session anchor, the session anchor further forwards the received strategy request to the uplink classifier ULCL to which the session anchor belongs, the uplink classifier ULCL executes the strategy, and the strategy is implemented in the subsequent packet forwarding process.
In one embodiment, the step of forwarding the policy to an upstream classifier, and the step of implementing the policy by the upstream classifier further includes:
and defining interface support capability control between the session anchor point and the uplink classifier so as to enable the session anchor point and the uplink classifier to interact with each other.
Specifically, an interface requiring interaction of support capability between the session anchor point and the ULCL is required, and interface support capability control between the session anchor point and the uplink classifier is required to be defined first, so that the session anchor point and the uplink classifier can interact with each other, the session anchor point can report a policy issued by an application server to the ULCL, and the ULCL implements the policy. Further, there is a definition process of an interface supporting capability interaction between the session anchor point and the uplink classifier ULCL, which may refer to a definition process of an application server providing a capability open interface by the session anchor point, and is not described herein again.

The technical scheme provided by the invention effectively shortens the path, avoids the mutual translation process of the control strategy by the current intermediate network element, simplifies the control logic and realizes the quick implementation of the AF strategy.

Specifically, after receiving the control information from the application server, the session anchor identifies and executes a policy, and according to the different policies, the UPF decision is executed at the session anchor or reported to the SMF for further decision. For example, after the AF informs a session anchor point of the deployment of an application server, the AF requires to reselect a server, the session anchor point recognizes the policy, and informs the SMF, and after the SMF receives the policy, taking a replacement anchor point as an example, the SMF determines that the server in the LDN (LiuLin intelligent Network distribution technology, LiuLin Delivery Network, LDN technology for short) has the AF, and selects a new session anchor point.
