Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art.

In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the present disclosure. One skilled in the relevant art will recognize, however, that the aspects of the disclosure may be practiced without one or more of the specific details, or with other methods, components, devices, steps, etc. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.

Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.
In some embodiments, referring to fig. 1, if members of a VN group are distributed among a plurality of UPF network elements, the UPF network elements may respectively establish an N19 interface connection between them, so as to forward data packets between members in the VN group. When a VN group involves a large number N of UPF network elements, the N19 interfaces of these UPF network elements are connected in a mesh manner, each UPF network element needs to maintain N-1N 19 interfaces, and in the service process, it is required to determine the UPF network element where the target member is located and forward the message to a different target UPF network element. And judging the destination address of the data message and distributing the data message to different UPF network elements. Because the number of interfaces maintained by each UPF network element is more, the workload of the UPF network element is larger, and the performance of the UPF network element is reduced.
In an embodiment of the present disclosure, in order to solve the above technical problems, a network element connection control method is provided. Next, a specific description will be given of a network element connection control method in the embodiment of the present disclosure with reference to fig. 2.
In step S210, an interface between a target UPF network element and a relay UPF network element is established in response to a session in which the target UPF network element in the local area network under the SMF network element has a group member.
In the embodiment of the disclosure, each SMF (Session Management function ) network element may include a 5G local area network, where the local area network refers to a computer group formed by interconnecting multiple computers in a certain area. The 5G local area network may comprise a plurality of UPF network elements and a plurality of terminal UEs. The SMF network element has a session management function and is responsible for processing the service of a user; the UPF network element has a user plane function.
To facilitate interaction between multiple terminal UEs, a relay UPF (User Plane Function ) network element may be provided in the local area network 5G LAN (Local Area Network ). The relay UPF network element is used for forwarding the message. The relay UPF network element may be a general UPF network element in the local area network, for example, may be any one of a plurality of UPF network elements included in the local area network; or may be a dedicated UPF network element, that is, an additional network element that is different from the multiple UPF network elements in the local area network, and is specifically determined according to actual requirements herein.
Referring to fig. 3, a plurality of UPF network elements, such as UPF1, UPF2, UPF3, UPF4, etc., may be included in the local area network. The relay UPF network element may be a separate UPF network element other than UPF1, UPF2, UPF3, UPF4. The type of the relay UPF network element may be the same as or different from the general UPF network element, and interaction with the SMF network element and each UPF network element may be achieved through message forwarding.
After setting up the relay UPF network element, an interface can be established between the target UPF network element with the session and the relay UPF network element in response to the session of VN (Virtual Network) group members of the target UPF network element in the local area network, where the interface can be an N19 interface, and the number of interfaces is one for each target UPF network element. The N19 interface is a user plane interface between two UPFs when using 5G LAN traffic, and routes traffic between different PDU sessions directly without using the N6 interface.
The target UPF network element may be other UPF network elements in the local area network than the relay UPF network element. The number of target UPF network elements may be one or more of the other UPF network elements, specifically determined according to the actual situation. Which UPF network elements are to be the target UPF network element may also be determined according to whether or not a session of a VN group member is present therein. The session in which a VN group member exists here refers to a session in which a target UPF network element exists a VN group member. The session of a VN group member refers to a session between a plurality of members in the VN group. The user groups with the mutual access function can be divided into the same logic domain, namely, specific terminals are divided into the same or different VN groups according to enterprise requirements, members in the same group can carry out intra-group communication, and different group members can carry out logic isolation. The information contained by the VN group may include, but is not limited to: 5G VN group identification, 5G VN group member information, 5G VN data.
The session may be a PDU (Protocol Data Unit) session. A PDU session refers to the process of communicating between a user terminal and a data network. After the PDU session is established, a data transmission channel between the terminal and the data network is established. The PDU session holds important information that may be related to charging, such as data routing for the user plane, qoS (Quality of Service ), charging, slicing, rate, etc.
Based on this, an N19 interface may be established between the target UPF element for each session in which a VN group member exists and the relay UPF element set in the local area network, so as to implement communications between the target UPF element and the relay UPF element. It should be noted that, only when the target UPF network element has a session of a VN group member, an interface between the target UPF network element and the relay UPF network element may be established. If there is no session for the VN group member, there is no need to establish an interface between the target UPF network element and the relay UPF network element.
On the basis, because a relay UPF network element exists, the connection between UPF network elements can be set to be star-shaped connection based on the relay UPF network element, and the relay UPF network element is used for forwarding data messages of all VN groups, and each UPF network element only needs to maintain an N19 interface between the relay UPF, so that the works of the UPF network element on the establishment, forwarding judgment and the like of the N19 interface are optimized, and the performance of the UPF network element is improved.
For example, referring to fig. 3, a relay UPF element may be provided in a local area network under a single SMF element. The SMF network element may include a plurality of UPF network elements, such as UPF1, UPF2, UPF3, UPF4, and if a plurality of UPF network elements each have a session of a group member, an N19 interface may be established between each UPF network element and the relay UPF network element.
Next, referring to fig. 2, in step S220, in response to a session establishment request of a group member, and in response to a message sent by a terminal in the group member to a terminal corresponding to the target member, a target service UPF network element of the target member is determined, and whether the target member belongs to a member of the service UPF network element of the terminal is determined based on the service UPF network element of the terminal.
In the embodiment of the disclosure, the terminal in the VN group member may send a session establishment request to the SMF network element. The SMF network element sends the session suggestion request to the service UPF network element, and the service UPF network element establishes a response and then sends the response to the SMF network element. The terminal sending the session establishment request may be any one of the group members. The session establishment request is used to establish a PUD session between members.
When a 5G LAN session is established by any terminal in the VN group members, the SMF network element issues an N4 rule to the service UPF network element, and meanwhile issues the relationship between the terminal UE and the service UPF network element to the relay UPF network element, so that the relay UPF network element stores the relationship tables of all members in the local area network under the SMF network element and the service UPF network element corresponding to each member. The UPF network element can be connected with the terminal. The serving UPF network element here may be a UPF network element for a terminal connection to establish a request for a session. In particular, when a session is established, the SMF network element may issue a new rule to the serving UPF network element of the terminal connection for which the session is being established. The new rule refers to a new N4 rule, and the new N4 rule may include a name of the VN group, a relationship between the terminal and the UPF network element, and the like. In addition, the relationship between the terminal and the service UPF network element may be issued to the relay UPF network element, so that the relay UPF network element stores a relationship table between all members included in the VN group member in the lan under the SMF network element and the service UPF network element corresponding to each member. The relationship table may determine a correspondence between the terminal represented by each member and the serving UPF network element.
After the session is established, a message can be sent to the terminal corresponding to the target member by responding to the terminal in the group member, the target service UPF network element of the target member is determined, and whether the target member belongs to the member of the service UPF network element of the terminal is judged based on all the terminals included in the service UPF network element of the terminal. The terminal in the group member used for sending the message may be any terminal in the group member, and the terminal may be the same as or different from the session establishment request. Any one of the terminals in the group member may send a message to the target member. The target member may be an intra-group member or an extra-group member, i.e. the target member receiving the message may be in the same VN group as the terminal sending the message, or may be in a different VN group. After determining the target member, the target service UPF network element of the target member may be determined according to the relationship table between all members in the group member and the corresponding service UPF network element issued by the SMF network element. Because the terminal corresponding to the target member can be connected with the UPF network element, the target service UPF network element of the target member can be uniquely determined. For example, referring to fig. 3, if the terminal corresponding to the target member is UE4, it may be determined that the serving UPF network element of UE4 is UPF4. If the terminal corresponding to the target member is UE2, it may be determined that the service UPF network element of UE2 is UPF2.
On the basis, the service UPF network element of the terminal sending the message can judge whether the target member belongs to the member of the service UPF network element, namely, whether the target member belongs to the member of the service UPF network element of the terminal sending the message is determined. For example, there may be a membership table for each service UPF element, where the membership table may include terminals corresponding to all members included in the service UPF element. Based on this, the service UPF network element of the terminal sending the message may determine, according to the member relation table of the service UPF network element itself, whether the target member belongs to a member of the service UPF network element itself of the terminal sending the message. When any one of the member relation tables is successfully matched, the target member can be considered as a member of the service UPF network element of the terminal for sending the message. Further, the message may be processed in different manners according to whether the message belongs to a member of the service UPF network element itself of the terminal sending the message.
For example, if the terminal sending the message is UE2, it may be determined that the service UPF network element of UE2 is UPF2, and the UPF2 may determine whether the target member UE4 receiving the message belongs to the UPF2 itself.
Next, in step S230, if the target member does not belong to a member of the service UPF network element of the terminal, the message is forwarded to the relay UPF network element through the interface, so as to perform a processing operation on the message through the relay UPF network element.
In the embodiment of the disclosure, the terminal corresponding to any group member in the VN group may send the message to the service UPF network element, and when the service UPF network element receives the message, the service UPF network element may process the message in different manners according to whether the target member receiving the message belongs to a member of the service UPF network element of the terminal sending the message.
When the target member does not belong to the member of the service UPF network element of the terminal, the message may be forwarded to the relay UPF network element through the established interface, and the relay UPF network element may further forward the message or discard the message according to the presence state of the target service UPF network element corresponding to the target member. The presence status is used to indicate whether a target service UPF network element corresponding to the target member can be found or not. When the presence state is a target service UPF network element corresponding to the presence target member, the relay UPF network element can further forward the message; when the presence state is that the target service UPF network element corresponding to the target member does not exist, the relay UPF network element can directly discard the message and stop the message sending process.
When the target member belongs to the member of the service UPF network element of the terminal, the terminal can directly send the message to the terminal corresponding to the target member without the set relay UPF network element.
A flow chart of the message processing is schematically shown in fig. 4, and referring to fig. 4, the method mainly comprises the following steps:
in step S410, the service UPF network element receives the VN group message;
in step S420, the service UPF network element determines whether the target member is under the present service UPF network element; if yes, go to step S430; if not, go to step S440;
in step S430, the service UPF network element forwards the message to the target member;
in step S440, the service UPF network element forwards the message to the relay UPF network element;
in step S450, the relay UPF network element queries whether the target member has a corresponding target service UPF network element; if yes, go to step S460; if not, go to step S470;
in step S460, the relay UPF network element forwards the message to the target service UPF network element of the target member, and further goes to step S430;
in step S470, the message is discarded.
In the embodiment of the disclosure, when the VN group member sends the 5G LAN message to other members, the other members may be target members for receiving the message. The service UPF network element corresponding to the member sending the message judges whether the member receiving the message is the member of the UPF, if not, the message is uniformly forwarded to the relay UPF network element, and the relay UPF network element forwards the message to the target service UPF corresponding to the target member according to the target member address; if the relay UPF does not find the target service UPF corresponding to the target member, the message is discarded.
For example, if the terminal UE1 sending the message and the target member UE5 receiving the message both belong to the UPF1, the service UPF network element (UPF 1) corresponding to the UE1 determines that the UE5 belongs to the present UPF network element, then the message is not required to be transferred to the N19 interface, and the message is forwarded by itself. In addition, the relationship between all UEs and the UPF network elements can be obtained according to the relationship table of the relay UPF network elements. If no relay UPF network element is established, multiple interfaces need to be established when UE1 needs to send a message to UE 4. Through the set relay UPF network element, the UE4 can be obtained on the UPF4 according to the relation table, and then the message can be directly sent to the UPF4 through the established N19 interface.
In the embodiment of the disclosure, the transmitted message is forwarded by the relay UPF network element, so that the process of establishing a plurality of interfaces to realize multi-layer forwarding when forwarding is performed by a plurality of UPF network elements is avoided, and convenience is improved. It should be noted that in the embodiment of the present disclosure, the number of SMF network elements may be one or more, a relay UPF network element may be set under each SMF network element, and an interface between a target UPF network element and a relay UPF network element may be established when a session of a group member exists, so that when a target member receiving a message does not belong to a member of a service UPF network element of a terminal sending the message, the message is forwarded to the relay UPF network element through the interface, and the message is forwarded or discarded through the relay UPF network element. In addition, the member information and rules under different SMFs can be transferred through interfaces between the plurality of SMF network elements, so that the plurality of SMF network elements can communicate conveniently.
A flow chart of the interaction is schematically shown in fig. 5, and with reference to fig. 5, mainly comprises the following steps:
in step S502, the terminal UE sends a PDU session establishment request to the SMF network element.
In the process of requesting PDU session establishment of 5G LAN, SMF network element issues new N4 rule to relay UPF network element. In addition, the original N4 rule exists between the terminal UE and the UPF network element, and the new N4 rule is different from the original N4 rule in terms of parameters and representation of parameters. The native N4 rules may contain intra-group member information, interfaces, and other UPF network element information. The new N4 rule may contain information of the group, the relation of the terminal and the UPF network element.
For example, the terminal UE1 sends an N4 rule to the UPF1 network element, where the N4 rule may include which members in the group on the UPF1 network element can perform local forwarding, which members on other UPF network elements, and the address of the corresponding N19 interface, etc. The new N4 rule between the UPF1 network element and the relay UPF network element may include the name of the group, the relation of the terminal UE and the UPF network element.
In step S504, the SMF network element sends an N4 session setup request to the serving UPF network element.
In step S506, the service UPF network element returns a session establishment response corresponding to the N4 session establishment request to the SMF network element;
in step S508, the SMF network element sends an N4 session setup request or an N4 session modification request to the relay UPF network element.
The N4 session establishment request or the N4 session modification request may include information such as a VN group identifier, a terminal UE identifier, and a service UPF network element.
In step S510, the relay UPF network element returns a response corresponding to the N4 session establishment request or the N4 session modification request to the SMF network element.
In step S512, the SMF network element returns a PDU session establishment response to the terminal UE.
In step S514, the terminal UE sends a message of the VN group to the serving UPF network element.
In step S516, the service UPF network element corresponding to the terminal determines that the target member is not in the present UPF network element, and forwards the message to the relay UPF network element.
In step S518, the relay UPF network element sends the message of the VN group to the target member according to the identifier of the target member.
In step S520, the relay UPF network element sends the packet of the VN group to the target service UPF network element corresponding to the target member according to the address of the target member.
In the embodiment of the disclosure, a relay UPF network element is arranged in a local area network of a 5G LAN, so that each UPF network element only needs to maintain one N19 interface, data messages which are not local to a terminal for a target member are uniformly forwarded to the relay UPF network element, and the SMF network element forwards the data messages between the UPF network elements by issuing a specific rule to the relay UPF network element, thereby reducing the maintenance and forwarding judgment processing of each UPF network element on the N19 interface, simplifying the conversion of the network connection of the N19 interface into star connection, and improving the processing capability of a single UPF network element.
