Detailed Description
Exemplary embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings.
The drawings are schematic illustrations of the present disclosure and are not necessarily drawn to scale. Some of the block diagrams shown in the figures may be functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in hardware modules or integrated circuits, or in a network, processor or microcontroller. Embodiments may be embodied in many different forms and should not be construed as limited to the examples set forth herein. The described features, structures, or characteristics of the disclosure may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough explanation of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that one or more of the specific details can be omitted, or one or more of the specific details can be replaced with other methods, components, devices, steps, etc., in implementing the aspects of the disclosure.
With the rapid development of 5G industrial internet services, the traffic forwarding requirement of a campus network is continuously increased; at present, by sinking a user plane function network element to a campus, the flow of the campus does not need to be forwarded by a session management function network element to improve forwarding efficiency, so as to solve the above problems to a certain extent.
In the related technology, the problems of network security, operator management and the like are solved by deploying a signaling gateway between an SMF and a UPF to forward signaling data; however, the redundant protection of the gateway device is implemented by increasing the number of signaling gateways, which may result in a multiple increase in the number of connections between network elements and the number of IP addresses to be converted, increase the complexity of connections between network elements, and increase the difficulty of network maintenance.
In view of the foregoing problems, the exemplary embodiments of the present disclosure first provide an information transmission method, which can reduce the complexity of the inter-network-element connection and the difficulty of network maintenance to some extent.
The following explains the noun terms appearing herein.
Session Management function network element (SMF): the UPF can be selected based on the granularity of the UE or session, IP addresses can be assigned, charging data collected, and a charging center connected.
User plane function network element (The User plane function, UPF): and the system is responsible for packet routing forwarding, policy enforcement, traffic reporting and the like. The UPF is an anchor point of the session and records the traffic forwarding amount.
Signaling Gateway (SG): and is responsible for relaying signaling messages between the SMF and the UPF.
The system architecture and application scenario of an operating environment of the above information transmission method are exemplarily described below with reference to fig. 1.
Fig. 1 shows a schematic diagram of a system architecture, which system architecture 100 may include a SMF cluster 101, a signaling gateway cluster 102, and a UPF cluster 103; wherein:
the SMF cluster 101 includes a first SMF 1011, a second SMF 1012, a third SMF 1013;
the signaling gateway cluster 102 includes a first signaling gateway 1021, a second signaling gateway 1022; the first signaling gateway 1021 and the second signaling gateway 1022 both store the mapping relationship between the identifier of the UPF and the address of the UPF, and the mapping relationship between the identifier of the SMF and the address of the SMF.
The UPF cluster 103 comprises a first UPF 1031, a second UPF 1032, and a third UPF 1033;
the SMF cluster 101, the signaling gateway cluster 102 and the UPF cluster 103 are sequentially connected, and the SMF cluster 101 performs information transmission with the UPF cluster 103 through the signaling gateway cluster 102; specifically, the signaling gateway cluster 102 forwards the information sent by the SMF cluster 101 to the UPF cluster 103, or forwards the information sent by the UPF cluster 103 to the SMF cluster 101.
In the related art, the signaling gateways in the signaling gateway cluster store the mapping relationship between the addresses of the SMF and the addresses of the UPF that are respectively supported, and the signaling gateways in the signaling gateway cluster share the preset mapping information in the present disclosure; such as: in a scenario that a signaling gateway cluster includes a first signaling gateway and a second signaling gateway, the configuration of the related art is that the first signaling gateway stores mapping information between addresses of SMFs supported by the first signaling gateway and addresses of UPFs, and the first signaling gateway is connected with the SMFs and the UPFs supported by the first signaling gateway based on the stored mapping information; the second signaling gateway stores the mapping information between the addresses of the SMFs supported by the second signaling gateway and the addresses of the UPFs, and the second signaling gateway is connected with the SMFs and the UPFs supported by the second signaling gateway based on the stored mapping information; thus, when the number of signaling gateways in the signaling gateway cluster is increased, the connection relationship is increased in multiples while the mapping information is increased in multiples; the configuration of the present disclosure is that the first signaling gateway and the second signaling gateway both store preset mapping information (i.e., signaling gateway cluster sharing preset mapping information: mapping relationship between identification of UPF and address of UPF, and mapping relationship between identification of SMF and address of SMF), and the first signaling gateway and the second signaling gateway are connected to all SMF and UPF based on sharing preset mapping information; in this way, the SMF or UPF is decoupled from the signaling gateway, and the number of connections and the number of converted addresses between network elements are not increased by the increase of the signaling gateway. Therefore, compared with the related art, the method and the device reduce the number of connections and converted addresses between the network elements, thereby reducing the complexity of the connections between the network elements and the difficulty of network maintenance.
Fig. 2 is a schematic diagram of an implementation flow of an information transmission method provided in the embodiment of the present disclosure, which may be executed by the first signaling gateway 1021, where the first signaling gateway is a signaling gateway in a signaling gateway cluster, and all signaling gateways in the signaling gateway cluster are deployed with preset mapping information, as shown in fig. 2, the method includes the following steps S201 to S203:
step S201, receiving downlink information sent by SMF; the downlink information carries the identifier of the target UPF;
step S202, determining the address of a target UPF corresponding to the identifier of the target UPF based on preset mapping information;
and step S203, sending the downlink information to the target UPF according to the address of the target UPF.
In the information transmission method, global preset mapping information is deployed in each signaling gateway of a signaling gateway cluster. After receiving the downlink information, a first signaling gateway in the signaling gateway cluster determines the address of a target UPF corresponding to the identification of the target UPF carried by the downlink information through preset mapping information, and then forwards the downlink information to the target UPF; because the address of the target UPF is determined according to the identification of the target UPF, the address of the target UPF does not need to be determined according to the address of the SMF, so that the SMF or the UPF is decoupled from the signaling gateway, the number of connections and the number of converted addresses between network elements (the SMF and the UPF) are reduced, and further, the connection complexity between the network elements and the maintenance difficulty of the network are reduced.
Each step in fig. 2 is explained in detail below.
Referring to fig. 2, in step S201, downlink information sent by the SMF is received; the downlink information carries the identification of the target UPF.
Wherein the identification of the UPF is used to distinguish different UPFs. In an embodiment, the identifier of the UPF may be a node number, or may be a Fully Qualified Domain Name (FQDN), which is not limited herein.
The downlink information refers to information sent by the SMF to the target UPF. The destination address initially carried by the downlink information is the address of the first signaling gateway, and the source address is the identifier of the SMF or the address of the SMF. In one embodiment, the SMF may be configured with an identifier of a target UPF and addresses of signaling gateway clusters supporting the SMF and the target UPF; thus, the SMF may carry the identifier of the UPF (final destination address), the identifier of the SMF, or the address of the SMF (source address), the address of the signaling gateway cluster (initial destination address), and send the downlink information to the first signaling gateway in the signaling gateway cluster.
In one embodiment, an association relationship between the address of the signaling gateway cluster supporting the SMF and the target UPF and the SMF or the target UPF may be established; in this way, the address of the cluster of signalling gateways can be determined at the same time as the target UPF is determined.
With continued reference to fig. 2, in step S202, the address of the target UPF corresponding to the identifier of the target UPF is determined based on the preset mapping information.
The preset mapping information comprises a mapping relation between the UPF identifier and the UPF address; therefore, in step S202, the address of the target UPF can be determined by querying the preset mapping relationship according to the identifier of the target UPF.
With continued reference to fig. 2, in step S203, the downlink information is sent to the target UPF according to the address of the target UPF.
In the process of forwarding the downlink information by the first signaling gateway, the first signaling gateway needs to determine a new destination address so as to forward the downlink information to a new destination; namely, the address of the target UPF is determined, and the downlink information is forwarded to the target UPF according to the address of the target UPF, so that the information transmission between the SMF and the UPF is realized.
Step S201 to step S203 may be understood as that the SMF transmits downlink information to the target UPF.
In one embodiment, before forwarding the downlink information to the target UPF, the signaling gateway cluster needs to replace the destination address of the downlink information; at this time, the destination address of the downlink information is an address of the signaling gateway cluster, and before step S203, the method further includes the following steps:
and replacing the destination address of the downlink information with the address of the target UPF.
In the process of forwarding the downlink information by the first signaling gateway, the initial destination address carried by the downlink information is the address of the signaling gateway cluster, so that after determining a new destination address, the first signaling gateway in the signaling gateway cluster needs to replace the initial destination address carried by the downlink information with the new destination address; namely, the address of the signaling gateway cluster carried by the downlink information is replaced by the address of the target UPF; therefore, the forwarding of the downlink information can be realized.
In one embodiment, the SMF needs the target UPF to respond to the downlink information it sends; at this time, the downlink information also carries SMF information, where the SMF information includes an identifier and an address of the SMF, and before step S203, the method further includes the following steps:
and replacing the SMF address carried by the downlink information with the address of the signaling gateway cluster, and reserving the SMF identifier.
The address of the SMF can be regarded as a source address carried by downlink information as required; at this time, the preset mapping information includes a mapping relationship between the identifier of the SMF and the address of the SMF; thus, the address of the SMF carried by the downlink information is replaced by the address of the signaling gateway cluster, so that the signaling gateway cluster receives the response information sent by the target UPF aiming at the downlink information; and the identification of the SMF is reserved, so that the target UPF returns response information to the SMF according to the identification of the SMF.
In one embodiment, the information of the SMF includes an identification of the SMF; at this time, the first signaling gateway forwards the downlink information through the following processes: firstly, determining an address of an SMF corresponding to an identifier of the SMF according to a preset mapping relation; secondly, the address of the SMF is replaced by the address of the signaling gateway cluster, and the identification of the SMF is reserved.
In summary, the information of the SMF at least includes an identification of the SMF.
In the information transmission method, the address of the SMF carried by the downlink information is replaced by the address of the signaling gateway cluster, so that the signaling gateway cluster receives the response information sent by the target UPF aiming at the downlink information; the mark of the SMF is reserved so that the target UPF returns the response information to the SMF according to the mark of the SMF; in this way, the first signaling gateway can forward the response information returned by the target UPF for the downlink information.
In an implementation manner, fig. 3 is a schematic view of an implementation flow of an information transmission method provided in this disclosure, which may be executed by the first signaling gateway 1021, where the first signaling gateway is a signaling gateway in a signaling gateway cluster, and all signaling gateways in the signaling gateway cluster are deployed with preset mapping information, as shown in fig. 3, the method includes the following steps S301 to S303:
step S301, receiving uplink information sent by a UPF; the uplink information carries the identification of the target SMF;
step S302, determining the address of a target SMF corresponding to the identifier of the target SMF based on preset mapping information;
and step S303, sending the uplink information to the target SMF according to the address of the target SMF.
In the information transmission method, global preset mapping information is deployed in each signaling gateway of a signaling gateway cluster. After receiving the uplink information, a first signaling gateway in the signaling gateway cluster determines the address of a target SMF corresponding to the identification of the target SMF carried by the uplink information through preset mapping information, and then forwards the uplink information to the target SMF; because the address of the target SMF is determined according to the identification of the target SMF, the address of the target SMF does not need to be determined according to the address of the UPF, thus, the SMF or the UPF is decoupled from the signaling gateway, the number of connections and the number of converted addresses between network elements (SMF and UPF) are reduced, and further, the complexity of the connections between the network elements and the difficulty of network maintenance are reduced.
Each step in fig. 3 is explained in detail below.
Referring to fig. 3, in step S301, uplink information sent by a UPF is received; the uplink information carries the identifier of the target SMF.
Wherein the identification of the SMF is used to distinguish between different SMFs. In one embodiment, the SMF identifier may be a node number or a Fully Qualified Domain Name (FQDN), which is not limited herein.
The uplink information refers to information transmitted by the UPF to the target SMF. The destination address initially carried by the uplink information is the address of the first signaling gateway, and the source address is the address of the UPF or the identifier of the UPF. In one embodiment, the identification of the target SMF and the addresses of signaling gateway clusters supporting the UPF and the target SMF may be configured for the UPF; thus, the UPF may carry the identifier of the SMF (final destination address), the identifier of the UPF or the address of the UPF (source address), the address of the signaling gateway cluster (initial destination address), and send the uplink information to the first signaling gateway in the signaling gateway cluster.
In one embodiment, an association relationship between the address of the signaling gateway cluster supporting the UPF and the target SMF and the UPF or the target SMF may be established; in this way, the address of the cluster of signalling gateways can be determined at the same time as the target SMF.
With continued reference to fig. 3, in step S302, the address of the target SMF corresponding to the identifier of the target SMF is determined based on the preset mapping information.
The preset mapping information comprises a mapping relation between an SMF identifier and an SMF address; therefore, in step S302, the address of the target SMF can be determined by querying the preset mapping relationship according to the identifier of the target SMF.
With continued reference to fig. 3, in step S303, the uplink information is sent to the target SMF according to the address of the target SMF.
In the process of forwarding the uplink information by the first signaling gateway, the first signaling gateway needs to determine a new destination address so as to forward the uplink information to a new destination; namely, the address of the target SMF is determined, and the uplink information is forwarded to the target SMF according to the address of the target SMF, so that the information transmission between the UPF and the SMF is realized.
Steps S301 to S303 may be understood as a process in which the UPF sends downlink information to the target SMF, but does not require the target SMF to respond to the downlink information.
In one embodiment, before forwarding the uplink information to the target SMF, the signaling gateway cluster needs to replace the destination address of the uplink information; at this time, the destination address of the uplink information is an address of the signaling gateway cluster, and before the step S303, the method further includes the following steps:
and replacing the destination address of the uplink information with the address of the target SMF.
In the process of forwarding the uplink information by the first signaling gateway, the initial destination address carried by the uplink information is the address of the signaling gateway cluster, and therefore, after determining a new destination address, the first signaling gateway in the signaling gateway cluster needs to replace the initial destination address carried by the uplink information with the new destination address; namely, replacing the address of the signaling gateway cluster carried by the uplink information with the address of the target SMF; therefore, the forwarding of the uplink information can be realized.
In one embodiment, the UPF requires the target SMF to respond to the upstream information it sends; at this time, the uplink information also carries information of the UPF, where the information of the UPF includes an identifier and an address of the UPF, and before the step S303, the method further includes the following steps:

Wherein, the address of the UPF can be regarded as a source address carried by the uplink information as required; at this time, the preset mapping information includes a mapping relationship between the identifier of the UPF and the address of the UPF; thus, the address of the UPF carried by the uplink information is replaced by the address of the signaling gateway cluster, so that the signaling gateway cluster receives the response information sent by the target SMF aiming at the uplink information; and the identification of the UPF is reserved, so that the target SMF returns the response information to the UPF according to the identification of the UPF.
