The 5GC introduces the concept of slicing, and provides guaranteed differentiated services for users. The wireless base station, the bearing network and the core network of the existing network adopt a static configuration mode for slice butt joint. The core network may be a network interface in which the UPF respectively interfaces with different VLANs of the bearer network when the N3 interface enables the subinterface, that is, the core network respectively corresponds to different slices, and different subinterfaces under the N3 interface of the UPF are statically configured with different slice IDs. The bearer network (IPRAN) configures corresponding VLAN channels for different slices. The wireless base station can configure different VLANs to bind different slice IDs and is in butt joint with corresponding VLANs of the bearer network.
In the existing network configuration mode, when the service or network is adjusted, such as VLAN and slice adjustment, the data adjustment of massive wireless base stations and the core network side configuration adjustment are difficult to be performed cooperatively, and the adjustment time of the wireless base stations is far longer than that of the core network, so that the service interruption time caused by network adjustment is increased.
Aiming at the problems in the related art, the disclosure provides a method for processing slice information, which is applied to a user plane functional network element. Fig. 1 shows a flow chart of a processing method of slice information, which, as shown in fig. 1, comprises at least the following steps:
step S110, a first incidence relation between the user incidence information and the slice information is determined, and a second incidence relation between the interface tunnel information and the user incidence information is determined.
And S120, establishing a third association relationship between the slice information and the interface tunnel information by using the first association relationship and the second association relationship.
Step S130, a fourth incidence relation between the interface tunnel information and the target interface is determined, and a target incidence relation among the slice information, the interface tunnel information and the target interface is established according to the third incidence relation and the fourth incidence relation.
In the exemplary embodiment of the disclosure, a plurality of association relations are established in the user plane functional network element, a data base and a theoretical support are provided for establishing a target association relation, and the problem that the two sides of the wireless side and the core network side are difficult to cooperate when the existing network service and network adjustment are carried out is solved from the perspective of the execution side. In addition, a dynamic target association relation among the slice information, the interface tunnel information and the target interface is established, so that the problem of a service terminal caused by static binding is solved, the time cost for establishing the target association relation is saved, the utilization efficiency of the network slice is further improved, and the application scene of the network slice is enriched.
Each step of the method for processing the slice information will be described in detail below.
In step S110, a first association relationship between the user association information and the slice information is determined, and a second association relationship between the interface tunnel information and the user association information is determined.
In an exemplary embodiment of the present disclosure, the UPF, as a 5GC network User plane network element, mainly supports routing and forwarding of UE (User Equipment) service data, data and service identification, action and policy execution, and the like.
When a user performs 5G (5th Generation Mobile Communication Technology, fifth Generation Mobile Communication Technology) registration, user association information may be acquired to establish a first association relationship between the user association information and slice information.
In an alternative embodiment, fig. 2 is a flowchart illustrating a method for establishing a first association relationship between user association information and slice information, where as shown in fig. 2, the method at least includes the following steps: in step S210, the user-related information is acquired, and the slice information in the user-related information is extracted.
The user association information may be registration and subscription information of a core network SMF (Service Management Function)/UPF when a user performs 5G registration and establishes PDU (Packet Data Unit) session connection. The user association information may be provided by the SMF network element.
In order to extract the slice information in the user-related information, information such as DNN (Data Network Name), SUPI (Subscription Permanent Identifier), TAI (tracking area identity), and slice in the user registration and Subscription information may be extracted to obtain the slice information.
In step S220, a first association relationship between the user association information and the slice information is established.
Since the slice information is extracted from the user-associated information, the user-associated information has an association relationship with the slice information, and thus, a first association relationship between the user-associated information and the slice information can be established and obtained through the association relationship.
In the exemplary embodiment, the first association relationship is established by extracting the slice information in the user association information, the corresponding relationship between the user association information and the slice information is followed, the establishment mode is simple and accurate, and data support is provided for subsequently establishing the target association relationship.
Further, a second association relationship between the interface tunnel information and the user association information can be established.
In an alternative embodiment, fig. 3 is a flowchart illustrating a method for establishing a second association relationship between interface tunnel information and user association information, where as shown in fig. 3, the method at least includes the following steps: in step S310, a packet session is created, and interface tunnel information corresponding to the packet session is extracted.
The user equipment initiates a Request for PDU Session establishment, namely a PDU Session establishment Request signaling. The PDU Session is a data packet Session, and a key field "PDU Session ID" carried by the PDU Session identifies an ID of the PDU Session applied for establishment, the ID is unique for each terminal, and the numbering range is limited to the UE.
Further, interface tunnel information associated with the packet session may also be extracted.
The interface tunnel information may be N3 interface tunnel information. The N3 interface tunnel information is associated with a packet session created by the user equipment.
The N3 interface is an interface between the NG RAN (5G radio access network) and the UPF, and uses the GTP-U protocol to perform tunneling of user data. The GTP-U Protocol is used for a tunneling Protocol between a pair of GTP-U tunnel end nodes, and encapsulates User data transmitted from the UE over an IP/UDP (Internet Protocol, User data packet Protocol).
In step S320, a second association relationship between the user association information and the interface tunnel information is established.
Since interface tunnel information such as the N3 interface tunnel information is associated with the packet drawing created by the user device, second association information between the user association information and the interface tunnel information can be established.
In the exemplary embodiment, the second association relationship is established by extracting the interface tunnel information corresponding to the data packet session, the corresponding relationship between the user association information and the interface tunnel information is followed, the establishment mode is simple and accurate, and data support is provided for subsequently establishing the target association relationship.
In step S120, a third association relationship between the slice information and the interface tunnel information is established by using the first association relationship and the second association relationship.
In an exemplary embodiment of the present disclosure, after determining a first association relationship between the user association information and the slice information and a second association relationship between the interface tunnel information and the user association relationship, a third association relationship between the slice information and the interface tunnel information may be established through the first association relationship and the second association relationship.
In an optional embodiment, a third association relationship between the slice information and the interface tunnel information corresponding to the user association information is established based on the user association information in the first association relationship and the second association relationship.
And taking the same user association information in the first association relationship and the second association relationship as a reference, so that the slice information corresponding to the user association information in the first association relationship corresponds to the interface tunnel information corresponding to the user association relationship in the second association relationship, and determining the correspondence between the slice information and the interface tunnel information as a third association relationship.
In step S130, a fourth association relationship between the interface tunnel information and the target interface is determined, and a target association relationship between the slice information, the interface tunnel information, and the target interface is established according to the third association relationship and the fourth association relationship.
In an exemplary embodiment of the present disclosure, a fourth association relationship between the interface tunnel information and the target interface may also be established.
In an alternative embodiment, fig. 4 is a flowchart illustrating a method for establishing a fourth association relationship between interface tunnel information and a target interface, where as shown in fig. 4, the method at least includes the following steps: in step S410, an uplink initial packet is obtained, and interface tunnel information and a target interface of the uplink initial packet are extracted.
When the core network SMF/UPF performs 5G registration and establishes PDU session connection, the corresponding uplink initial message can also be obtained. The uplink initial message includes an incoming terminal interface identifier/VLAN, a GTP tunnel, and the like.
GTP is a set of IP-based higher layer protocols, is located in protocols such as TCP (Transmission Control Protocol)/IP or UDP/IP, and is mainly used for supporting communication protocols of General Packet Radio Service (GPRS) in GSM (Global System for Mobile Communications ), UMTS (Universal Mobile Telecommunications System), and LTE (Long Term Evolution) networks.
Further, the interface tunnel information and the target interface of the uplink initial message are extracted. It should be noted that the target interface and the VLAN channel have a one-to-one correspondence relationship, and therefore, after the target interface is determined, the determination is equivalent to the determination of the VLAN channel.
In step S420, a fourth association relationship between the interface tunnel information and the target interface is established.
Since the interface tunnel information extracted from the same uplink initial message has an association relationship with the target interface, the interface tunnel information and the target interface can be associated with each other through the same uplink initial message to obtain a fourth association relationship.
In the exemplary embodiment, the fourth association relationship is established by extracting the interface tunnel information and the target interface in the uplink initial message, the association relationship between the interface tunnel information and the target interface is followed, the establishment mode is simple and accurate, and data support is provided for subsequently establishing the target association relationship.
After the fourth incidence relation is determined, a target incidence relation among the slice information, the interface tunnel information and the target interface can be established through the third incidence relation and the fourth incidence relation.
In an optional embodiment, a target association relationship is established among the slice information, the target interface and the interface tunnel information corresponding to the interface tunnel information based on the interface tunnel information in the third association relationship and the fourth association relationship.
And taking the same interface tunnel information in the third association relation and the fourth association relation as a reference, so that the slice information corresponding to the interface tunnel information in the third association relation corresponds to the target interface corresponding to the interface tunnel information in the fourth association relation, and a target association relation can be formed among the interface tunnel information, the slice information and the target interface.
Since the target association relationship is generated based on the user's registration at this time, the target association relationship is a dynamic association relationship between the three.
It should be noted that the target association relationship may also be a dynamic association relationship between only the slice information and the target interface, and this exemplary embodiment is not particularly limited in this respect.
After the target association relationship is generated, a dynamic relationship table recording the target association relationship can be generated, so that the target association relationship can be edited through the dynamic relationship table.
In an alternative embodiment, fig. 5 is a flowchart illustrating a method for editing a target association relationship through a dynamic relationship table, where as shown in fig. 5, the method at least includes the following steps: in step S510, a dynamic relationship table is generated that records the slice information, the interface tunnel information, and the target association relationship of the target interface.
The dynamic relation table is used for recording the target incidence relation among the slice information, the interface tunnel information and the target interface information. After the dynamic relation table is established, the forwarding of the service data can be realized according to the target association relation in the dynamic relation table.
In step S520, when the user equipment corresponding to the user association information goes offline, the target association relationship corresponding to the user association information is deleted in the dynamic relationship table.
Since the target association relationship is generated based on the user at the time of 5G registration, when the user equipment used by the user goes offline, it indicates that the target association relationship no longer exists, and therefore, the corresponding target association relationship can be deleted from the dynamic relationship table.
In the exemplary embodiment, the target association relationship is recorded and edited through the dynamic relationship table, so that the target association relationship is in a dynamic binding state, and the problem that the wireless side and the core network side are difficult to cooperate due to static binding is solved.
The following describes a detailed description of a method for processing slice information in the embodiment of the present disclosure in conjunction with an application scenario.
Fig. 6 shows a schematic structural diagram of a method for processing slice information in an application scenario, and as shown in fig. 6, a wireless base station, a bearer network, and a core network of a current network adopt a static configuration mode for slice docking. The static configuration mode is realized on two sides of the GNB (gNodeB, 5G base station) side and the UPF side.
The core network may be a network interface in which the UPF respectively interfaces with different VLANs of the bearer network when the N3 interface enables the subinterface, that is, the core network respectively corresponds to different slices, and different subinterfaces under the N3 interface of the UPF are statically configured with different slice IDs. The bearer network (IPRAN) configures corresponding VLAN channels for different slices. The wireless base station can configure different VLANs to bind different slice IDs and is in butt joint with corresponding VLANs of the bearer network.
In the static configuration mode, when the service or network is adjusted, such as VLAN and slice adjustment, the data adjustment of massive wireless base stations and the core network side configuration adjustment are difficult to be performed cooperatively, and the adjustment time of the wireless base stations is far longer than that of the core network, so that the service interruption time caused by network adjustment is prolonged
However, the method for establishing the target association relationship of the dynamic binding of the slice information, the target interface and the interface tunnel information is only implemented on one side of the user plane functional network element, and is not implemented on two sides of the 5G base station and the user plane functional network element, so that the problem that the wireless side and the core network side are difficult to cooperate when the existing network service and the network are adjusted can be solved from the aspect of the execution side.
Fig. 7 is a flowchart illustrating a processing method of slice information in an application scenario, and as shown in fig. 7, when a user performs 5G registration, user association information may be acquired to establish a first association relationship between the user association information and the slice information.
And acquiring the user associated information, and extracting the slice information in the user associated information.
The user association information may be registration and subscription information of the core network SMF/UPF when the user performs 5G registration and establishes PDU session connection.
In order to extract slice information in the user-related information, information such as DNN, SUPI, TAI, and slice in the user registration and subscription information may be extracted to obtain slice information.
And establishing a first association relation between the user association information and the slice information.
Since the slice information is extracted from the user-associated information, the user-associated information has an association relationship with the slice information, and thus, a first association relationship between the user-associated information and the slice information can be established and obtained through the association relationship.
And creating a data packet session and extracting interface tunnel information corresponding to the data packet session.
The user equipment initiates a PDU Session Establishment application, namely a PDU Session Establishment Request signaling. The PDU Session is a data packet Session, and a key field "PDU Session ID" carried by the PDU Session identifies an ID of the PDU Session applied for establishment, the ID is unique for each terminal, and the numbering range is limited to the UE.
Further, interface tunnel information associated with the packet session may also be extracted.
The interface tunnel information may be N3 interface tunnel information. The N3 interface tunnel information is associated with a packet session created by the user equipment.
And establishing a second association relation between the user association information and the interface tunnel information.
Since interface tunnel information such as the N3 interface tunnel information is associated with the packet drawing created by the user device, second association information between the user association information and the interface tunnel information can be established.
After a first association relation between the user association information and the slice information and a second association relation between the interface tunnel information and the user association relation are determined, a third association relation between the slice information and the interface tunnel information can be established through the first association relation and the second association relation.
And establishing a third association relation between the slice information corresponding to the user association information and the interface tunnel information according to the user association information in the first association relation and the second association relation.
And taking the same user association information in the first association relationship and the second association relationship as a reference, so that the slice information corresponding to the user association information in the first association relationship corresponds to the interface tunnel information corresponding to the user association relationship in the second association relationship, and determining the correspondence between the slice information and the interface tunnel information as a third association relationship.
And acquiring an uplink initial message, and extracting interface tunnel information and a target interface of the uplink initial message.
When the core network SMF/UPF performs 5G registration and establishes PDU session connection, the corresponding uplink initial message can also be obtained.
Further, the interface tunnel information and the target interface of the uplink initial message are extracted. It should be noted that the target interface and the VLAN channel have a one-to-one correspondence relationship, and therefore, after the target interface is determined, the determination is equivalent to the determination of the VLAN channel.
And establishing a fourth incidence relation between the interface tunnel information and the target interface.
Since the interface tunnel information extracted from the same uplink initial message has an association relationship with the target interface, the interface tunnel information and the target interface can be associated with each other through the same uplink initial message to obtain a fourth association relationship.
And establishing a target association relation among the slice information, the target interface and the interface tunnel information corresponding to the interface tunnel information by taking the interface tunnel information in the third association relation and the fourth association relation as a basis.
And taking the same interface tunnel information in the third association relation and the fourth association relation as a reference, so that the slice information corresponding to the interface tunnel information in the third association relation corresponds to the target interface corresponding to the interface tunnel information in the fourth association relation, and a target association relation can be formed among the interface tunnel information, the slice information and the target interface.
Since the target association relationship is generated based on the user's registration at this time, the target association relationship is a dynamic association relationship between the three.
After the target association relationship is generated, a dynamic relationship table recording the target association relationship can be generated, so that the target association relationship can be edited through the dynamic relationship table.
And generating a dynamic relation table for recording the slice information, the interface tunnel information and the target association relation of the target interface.
The dynamic relation table is used for recording the target incidence relation among the slice information, the interface tunnel information and the target interface information.
And when the user equipment corresponding to the user association information is offline, deleting the target association relation corresponding to the user association information in the dynamic relation table.
Since the target association relationship is generated based on the user at the time of 5G registration, when the user equipment used by the user goes offline, it indicates that the target association relationship no longer exists, and therefore, the corresponding target association relationship can be deleted from the dynamic relationship table.
In the method for processing the slice information in the application scene, a plurality of incidence relations are established in a user plane functional network element, a data base and a theoretical support are provided for establishing a target incidence relation, and the problem that the two sides of a wireless side and a core network side are difficult to cooperate when the current network service and network adjustment are carried out is solved from the aspect of an execution side. In addition, a dynamic target association relation among the slice information, the interface tunnel information and the target interface is established, so that the problem of a service terminal caused by static binding is solved, the time cost for establishing the target association relation is saved, the utilization efficiency of the network slice is further improved, and the application scene of the network slice is enriched.
