Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure.
Unless specifically stated otherwise, the descriptions of "first", "second", etc. in this disclosure are used to distinguish different objects, and are not used to indicate the meaning of size or timing, etc.
Fig. 1 illustrates a schematic diagram of a shunt system of some embodiments of the present disclosure.
As shown in fig. 1, the shunt system 100 of this embodiment includes: the core network device 110 includes, for example, a core network SMF network element 111, a core network UPF network element 112, etc., a proxy gateway 120, and a sinking edge UPF network element 130.
The core network device 110 provides network services such as terminal access and mobility management, authentication management, session management, and policy control. The core network SMF network element 111 performs N4 signaling interaction with the edge UPF network element 130, and completes a offloading function of an UL CL (Uplink Classifier) local network in cooperation with the edge UPF network element 130. The core network UPF network element 112 may provide data services of an external network for the terminal, and an N9 interface is between the core network UPF network element 112 and the edge UPF network element 130. The local Network and the external Network are both Data Networks (DNs).
The proxy gateway 120 is, for example, a custom InterWorking Function (C-IWF) gateway. The proxy gateway 120 includes functions of signaling proxy forwarding, routing management, message processing, transmission encryption, authentication and the like, provides a security proxy and an access authentication management function for customizing signaling/data of a private network sink access network element, can perform switching proxy, adjustment and adaptation on signaling interacted by various network elements, and meets and supports the signaling interaction function of various network elements.
The edge UPF network element 130 is a sinking private network element device, and is configured to provide edge access and enterprise customized network services for a user, and needs to perform N4 signaling interaction with the core network SMF network element 111 to complete a offloading function of the UL CL local network.
The UL CL is inserted into the edge UPF network element 130, so that the edge UPF network element 130 performs offloading based on the traffic detection rule and the traffic forwarding rule provided by the core network SMF network element 111, and the terminal does not sense the insertion and deletion of the UL CL.
In some embodiments, the core network SMF network element 111 is configured to send the offload message; a proxy gateway 120 configured to perform the offloading method of any of the embodiments to adapt the offloading message; and the edge UPF network element 130 is configured to send the response message according to the adapted offloading message and perform offloading. The specific procedures are described with reference to the following examples.
According to the embodiment of the disclosure, whether the manufacturer of the core network SMF network element is the same as the manufacturer of the edge UPF network element is judged through the proxy gateway, if the manufacturers are different, the message communicated between the edge UPF network element and the core network SMF network element is adapted and then sent, so that the edge UPF network element and the core network SMF network element under different manufacturers can be communicated normally.
Fig. 2 (a) and 2 (b) show schematic diagrams of two upstream offload design logics of different vendors for some embodiments of the present disclosure.
As shown in fig. 2 (a), a vendor sets a ULCL and a PSA (PDU Session Anchor) in the edge UPF network element 130, and an N9 interface is also between the ULCL and the PSA. The corresponding splitting paths of the upstream splitting design logic shown in fig. 2 (a) are N3-N9-N6. Where N3, N9, N6 represent network interfaces.
As shown in fig. 2 (b), a vendor only has a ULCL in the edge UPF network element 130. The corresponding splitting paths of the upstream splitting design logic shown in fig. 2 (b) are N3-N6.
Fig. 3 illustrates a schematic diagram of a proxy network-based offloading method according to some embodiments of the present disclosure.
As shown in fig. 3, the flow dividing method of this embodiment includes the following steps.
Suppose that the manufacturer of the edge UPF network element is manufacturer a, the manufacturers of the core network SMF network element and the core network UPF network element are manufacturers B, and the manufacturer of the core network SMF network element is different from the manufacturer of the edge UPF network element. Vendor a and vendor B employ different upstream offload design logic.
In step 300, initially, the terminal and the SMF network element of the core network interactively establish a PDU session, request access to the internal network, trigger UL CL offload, and also request access to the external network. And after passing the security authentication, the edge UPF network element establishes a security channel and can perform communication interaction with the core network. And the edge UPF network element establishes coupling with the core network SMF network element through the proxy gateway.
The terminal is, for example, user Equipment (UE).
In step 310, the core network SMF network element selects an edge UPF network element as an anchor point of the PDU session and establishes an UL CL session, and the core network SMF network element sends a breakout message (e.g., an UL CL message) to the proxy gateway for the edge UPF network element, where the breakout message includes a traffic detection rule and a traffic forwarding rule for indicating which traffic should be forwarded to which network element (e.g., the core network UPF network element or the edge UPF network element).
If the terminal requests to access the internal network, the shunting message comprises a group of corresponding flow detection rules and flow forwarding rules, and the flow detection rules and the flow forwarding rules are used for indicating that the flow indicated by the flow detection rules is forwarded to the edge UPF network element; if the terminal requests to access the external network, the shunting message comprises another group of corresponding flow detection rules and flow forwarding rules, and the flow detection rules and the flow forwarding rules are used for indicating that the flow indicated by the flow detection rules is forwarded to a core network UPF network element.
The traffic Detection Rule is, for example, PDR (Packet Detection Rule). The traffic Forwarding Rule is, for example, FAR (Forwarding Action Rule).
In step 320, after receiving the shunting message, the proxy gateway first determines whether the manufacturer of the SMF network element of the core network is the same as the manufacturer of the UPF network element of the edge, and if so, only replaces the related routing information in the message; if the difference is different, the message is adapted, and the message is converted into a message which can be identified by the manufacturer to which the edge UPF network element belongs.
The relevant routing information in the replacement message includes, for example: and respectively replacing the source address and the destination address of the shunting message by a proxy gateway address and an edge UPF network element address from the SMF network element address and the proxy gateway address of the core network.
The proxy gateway can pre-store the corresponding relation between the network element address and the manufacturer to which the network element belongs, then acquire the manufacturer information to which the core network SMF network element belongs according to the address information of the core network SMF network element, and acquire the manufacturer information to which the edge UPF network element belongs according to the address information of the edge UPF network element. Or, the proxy gateway may pre-store the correspondence between the network element address and the manufacturer, the model, and the version of the network element, then obtain the manufacturer information, the model, and the version information of the core network SMF network element according to the address information of the core network SMF network element, and obtain the manufacturer information, the model, and the version information of the edge UPF network element according to the address information of the edge UPF network element.
Wherein adapting the message comprises: and adapting a first uplink shunt rule in the shunt message, which is matched with a first uplink shunt design logic corresponding to a manufacturer to which the core network SMF network element belongs, to a second uplink shunt rule matched with a second uplink shunt design logic corresponding to a manufacturer to which the edge UPF network element belongs.
Wherein adapting the message comprises: and adapting a first uplink shunt rule in the shunt message, which is matched with a first uplink shunt design logic corresponding to a manufacturer, a model and a version of the core network SMF network element, to a second uplink shunt rule matched with a second uplink shunt design logic corresponding to a manufacturer, a model and a version of the edge UPF network element.
For example: if the first uplink shunting rule is an N3-N9-N6 shunting path and the second uplink shunting rule is an N3-N6 shunting path, adapting the N3-N9-N6 shunting path in the shunting message to be the N3-N6 shunting path; or if the first uplink splitting rule is an N3-N6 splitting path and the second uplink splitting rule is an N3-N9-N6 splitting path, adapting the N3-N6 splitting path in the splitting message to be the N3-N9-N6 splitting path.
Wherein adapting the message comprises: and supplementing the private attributes corresponding to the manufacturers to which the edge UPF network elements belong in the shunting messages. Private attributes include, for example: the identification session belongs to the private attribute of the upstream offload. For example, the edge UPF network element has a private attribute "ZTEPsa2F" to identify that the session belongs to the ULCL, the private attribute is not present in the breakout message, and the proxy gateway supplements the private attribute in the breakout message to enable the edge UPF network element to identify the breakout message.
In step 330, the proxy gateway sends the adapted offload message to the edge UPF network element.
In step 340, after receiving the shunting message, the edge UPF network element sends a response message to the proxy gateway.
In step 350, after receiving the response message, the proxy gateway first determines whether the manufacturer of the SMF network element of the core network is the same as the manufacturer of the edge UPF network element, and if so, only replaces the related routing information in the message; if the difference is not the same, the message is adapted, and the message is converted into a message which can be identified by a manufacturer of the SMF network element of the core network.
The related routing information in the replacement message includes, for example: and replacing the source address and the destination address of the response message by the proxy gateway address and the core network SMF network element from the edge UPF network element address and the proxy gateway address respectively.
Wherein adapting the message comprises: and deleting the corresponding private attribute of the manufacturer to which the edge UPF network element belongs in the response message. For example, the edge UPF network element has a private attribute "ZTEPsa2F" identifying that the session belongs to the ULCL, the private attribute is present in the response message, and the proxy gateway deletes the private attribute in the response message so that the core network SMF network element can recognize the response message.
In step 360, the proxy gateway sends the adapted message to the SMF network element of the core network.
In step 370, the core network SMF element updates the core network UPF element rule to provide the tunnel information for the terminal to access the external network.
At this time, the terminal can access the internal network through the edge UPF network element to realize local distribution. If the edge UPF network element adopts the uplink splitting design logic shown in fig. 2 (a), the terminal performs splitting through the splitting paths N3-N9-N6. If the edge UPF network element adopts the uplink splitting design logic shown in fig. 2 (b), the terminal performs splitting through the splitting paths N3-N6. At this time, the terminal can also access the external network through the UPF network element of the core network.
In step 380, the SMF network element of the core network updates RAN (radio access network) side information and provides the information of the distribution channel corresponding to the edge UPF network element.
According to the embodiment of the disclosure, whether the manufacturer of the core network SMF network element is the same as the manufacturer of the edge UPF network element is judged through the proxy gateway, if the manufacturers are different, the message communicated between the edge UPF network element and the core network SMF network element is adapted and then sent, so that the edge UPF network element and the core network SMF network element under different manufacturers can be communicated normally.
