detailed description

As a new generation of communication technology, 5G has many advantages such as high bandwidth, low latency, high reliability, and ubiquitous network, which promotes the rapid development and change of vertical industries such as smart medical care, smart education, and smart agriculture. MEC is one of the key technologies in the evolution of 5G. It is an IT service platform with wireless network information application programming interface (API, Application Programming Interface) interaction capabilities, as well as computing, storage, and analysis capabilities. 5G networks relying on MEC can provide users with localized services, thereby improving user experience and giving full play to the value of edge networks.

The 5G industry private network is based on 5G+MEC technology and is oriented to different industry demand scenarios. In order to provide targeted solutions, it can introduce different technology combinations such as service quality (QoS, Quality of Service), end-to-end network slicing, network Open capabilities, edge cloud, etc.

The 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) provides a reference design for the combination of 5GC and MEC in standards TS23.501 and TS23.502. Figure 1 is a schematic diagram of the architecture of the combination of 5GC and MEC defined by 3GPP, as shown in Figure 1:

MEC is composed of three parts: MEC platform infrastructure layer, MEP and MEC application layer (ME APP). Among them, the platform infrastructure layer is based on a general server and adopts the method of network function virtualization (NFVi, Network Functions Virtualization) to provide the underlying hardware for MEP computing, storage and other physical resources. The MEP includes ME Services (MEServices) and application functions (AF, Application Function). ME Services provides a platform for multiple applications to run independently for ME APP. AF includes functions such as data distribution, wireless network information management, network acceleration, and business registration, and is open to ME APP through an open API. MEPs are used to implement edge computing functions and carry edge computing applications. Based on the NFVi architecture, ME APP encapsulates the functional components of MEP into virtual applications, including local distribution, wireless caching, augmented reality, business optimization, positioning and other applications, and opens them to third-party business applications through standard interfaces to realize capability openness with call.

In order to enable vertical industries to have low-latency, high-bandwidth, and high-reliability edge applications, the UPF is lowered to the campus to be close to the MEC. When the UE accesses the MEC through the 5GC, the user access request is forwarded to the MEC edge server through the local distribution function of the UPF. There are three types of local offload technologies in the 5G network currently defined by 3GPP:

1. Uplink Classifier (ULCL, Uplink Classifier) mode. ULCL is a function of UPF. It can locally forward packets that meet the filtering rules issued by SMF. Among them, the filtering rules issued by SMF represent the five-tuple of data packets based on UE, that is, source IP address and destination IP address. , source port number, destination port number, protocol type. ULCL supports PDU sessions with Ethernet type IPv4/IPv6/IPv4v6. The insertion and deletion of ULCL is determined by the SMF and completed by controlling the UPF through the N4 interface. Third-party platforms such as MEP can configure ULCL forwarding rules through the network opening function of 5GC.

2. IPv6 bifurcation point (BP, Branching Point) mode. This method only supports PDU sessions under IPv6 type. UPF implements local distribution based on the IPv6 address prefix of the data packet. Similar to the ULCL method, the insertion and deletion of BPs are determined by the SMF and completed by controlling the UPF through the N4 interface. Third-party platforms such as MEP can configure BP forwarding rules through the network opening function of 5GC.

3. Dedicated DNN mode. Each MEC corresponds to a dedicated DNN. When a UE creates a PDU session to access a MEC, it needs to carry the DNN corresponding to the MEC it wants to access in order to successfully complete the access. According to the DNN carried in the PDU session, the 5GC selects the corresponding UPF to forward the UE's access request to the corresponding MEC.

The above-mentioned local distribution method can enable terminals to access local MEPs. However, in the actual application scenarios of vertical industries, in addition to the requirements for terminals to access local MEPs, there is also a requirement for wide-area interconnection between MEPs. There is also a terminal Access to other non-local MEP requirements. Such as data sharing between different hospitals in the smart medical industry, remote collaborative diagnosis and other scenarios. In related technologies, the UPF defined by 3GPP only supports the PDU session from the UE to the data network, and does not support the connection between data networks. That is to say, UPF only supports the data connection between the terminal and the MEP, and does not support the data connection between the MEPs. In addition, one MEC may correspond to multiple DNNs. Correspondingly, the MEPs in each MEC also correspond to multiple DNNs. In practical applications, the UE cannot automatically obtain the DNNs corresponding to each MEP and the information corresponding to the application in the MEP to be accessed. Server IP address. If you want to access a certain MEP, you need to manually configure the DNN of the MEP to be accessed and the IP address of the application server. If you want to access multiple MEPs, you need to manually switch to the DNN corresponding to each MEP. In this way, it is inefficient for the UE to obtain the DNN corresponding to the MEP, and the user experience is not good.

Based on this, an embodiment of the present application provides a method for accessing a system. The UE sends a first request to the first system for accessing the second system, and the first system forwards the first request to the The second device directly connected to the second system, so that the second system returns a first response to the UE based on the first request forwarded by the second device, and the first response carries information of the second system used to access the second system DNN, in this way, when the UE wants to access the second system, it can obtain the DNN corresponding to the second system through the first system, and does not need to manually configure the DNN of the second system that needs to be accessed, thereby improving the UE's ability to obtain the DNN corresponding to other systems Efficiency, also improves the efficiency of UE accessing other systems. And by setting the first device and the second device, the wide-area interconnection and intelligent routing functions between different systems are realized.

The application will be further described in detail below in conjunction with the accompanying drawings and embodiments. For the convenience of understanding, this application takes the system as an MEP and the device as a gateway as an example to further describe the method for accessing the system provided by this application in detail.

Fig. 2 is a schematic diagram of the implementation flow of the method for accessing the system provided by the embodiment of the present application. The method is applied to the first system. As shown in Fig. 2, the method includes:

Step 201: Receive a first request from a UE; the first request is used to request access to a second system. Here, the UE can directly access the first MEP through the UPF, but cannot directly access the second MEP through the UPF. If the UE needs to access the second MEP, it sends a first request for accessing the second MEP to the first MEP, and the first MEP receives the first request from the UE.

It should be noted that, in this embodiment of the application, the first system is the first MEP, the second system is the second MEP, the first device is the first gateway, and the second device is the second gateway to access the A systematic approach is described.

Step 202: The first device directly connected to the first system forwards the first request to the second device directly connected to the second system, so that the second system forwards the request based on the information forwarded by the second device. The first request returns a first response to the UE; the first response carries the DNN of the second system for accessing the second system.

Here, the first MEP is directly connected to the first gateway, the first gateway is directly connected to the second gateway, and the second gateway is directly connected to the second MEP. After receiving the first request, the first MEP first forwards the first request to the first gateway, forwards the first request to the second gateway through the first gateway, and finally forwards the first request to the second gateway through the second gateway. Two MEPs. After receiving the first request, the second MEP returns a first response to the UE based on the first request.

The UE needs to obtain the DNN corresponding to the second MEP before it can access the second MEP, so the first response returned by the second MEP carries the DNN of the second MEP.

Figure 3 is a schematic diagram of a 5G industry cloud-network integration architecture provided by the embodiment of the present application, as shown in Figure 3:

Based on the combined architecture of 5GC and MEC defined by 3GPP in Figure 1, a new device, Industry Gateway (IGW, Industry Gateway), is introduced. IGW is deployed between UPF and MEP, and is directly connected to MEP.

Figure 4 is a schematic diagram of another 5G industry cloud-network integration architecture provided by the embodiment of the present application, as shown in Figure 4:

MEP1 is directly connected to IGW1, and MEP2 is directly connected to IGW2. IGW1 and IGW2 are connected through the I5 interface. In this way, the communication connection between MEP1 and MEP2 can be realized through IGW1 and IGW2.

In an embodiment, the first request carries the identifier of the second system, and the first device directly connected to the first system forwards the first request to the second device directly connected to the second system. equipment, including:

Acquiring the identifier of the second system carried in the first request;

Based on the obtained identifier of the second system, the first request is forwarded to the second device by the first device.

Here, the first request is used to request access to the second MEP, and the first request carries the identifier of the second MEP. After receiving the first request, the first MEP first performs authorization verification on the first request sent by the UE, and verifies whether the UE is authorized to send the first request to the first MEP. After the permission verification is successful, the first MEP obtains the identity of the second MEP carried in the first request, and after obtaining the identity of the second MEP, the first MEP determines that the UE wants to access the second MEP, so it forwards the first request to to the second gateway corresponding to the second MEP.

By obtaining the identity of the second MEP in the first request and forwarding the first request based on the identity of the second MEP, the first request can be forwarded to the gateway of the corresponding MEP in a targeted manner, which improves the UE's ability to obtain the desired Efficiency of the DNN for accessing MEPs.

In an embodiment, the first request carries an identifier of an application configured in the second system.

Here, the first request sent by the UE carries the identifier of the configuration application in the second MEP to be accessed, and if the UE wants to access the configuration application, it needs to obtain the server IP address corresponding to the configuration application. After the first MEP forwards the first request to the second MEP through the first gateway and the second gateway, after receiving the first request, the second MEP obtains the identifier of the configuration application carried in the first request. Determine the server IP address corresponding to the setting application according to the identification of the setting application, and write the server IP address into the first response and return it to the UE.

By carrying the identifier of the configuration application in the first request, the server IP address corresponding to the configuration application can be obtained from the second MEP, so that the UE can access the configuration application in the second MEP based on the first response.

In an embodiment, before the first device directly connected through the first system forwards the first request to the second device directly connected through the second system, the method further includes:

Sending first configuration information to the first device, so that the first device establishes a connection with the second device based on the first configuration information; wherein,

The first configuration information represents a communication configuration corresponding to the second system.

Here, before forwarding the first request through the first gateway, a communication connection is first established between the first gateway corresponding to the first MEP and the second gateway corresponding to the second MEP, so as to realize wide-ranging communication between the first MEP and the second MEP. domain interconnection. A specific method for establishing a connection is: sending the first configuration information to the first gateway, so that the first gateway establishes a connection with the second gateway based on the first configuration information. The first configuration information represents the communication configuration corresponding to the second MEP.

By sending the first configuration information to the first gateway and establishing a connection between the first gateway and the second gateway, the wide-area interconnection between the first MEP and the second MEP can be realized, so that the UE can obtain the second MEP through the first MEP. The DNN corresponding to the MEP.

In an embodiment, the first configuration information includes at least one of the following: routing rules between the first system and the second system, services between the first system and the second system rules, the access duration between the first system and the second system, and the priority of each rule between the first system and the second system.

Here, the first configuration information specifically includes at least one of the following:

A routing rule between the first MEP and the second MEP. The routing rule is used to set the routing configuration for communication between the first MEP and the second MEP, and the routing rule includes a routing rule identifier, a packet detection rule, a packet processing mode, and a packet destination interface. Wherein, the routing rule identifier is used to uniquely identify a routing rule within a dedicated network system. Packet inspection rules include the direction of packet forwarding: uplink in to the network server and downlink out to the terminal, and IP packet quintuple: source IP address, destination IP address, source port, destination port, protocol number of the transport layer protocol . Packet processing methods include discarding, forwarding, copying, and retransmission. The packet destination interface includes an identifier of the destination interface.

Service rules between the first MEP and the second MEP. The service rules specifically include bandwidth requirements, delay requirements, reliability requirements, and traffic restriction requirements for communication between the first MEP and the second MEP.

The access duration between the first MEP and the second MEP. The access time represents a time limit for communication between the first MEP and the second MEP, and if the communication time exceeds the access time, the first gateway will disconnect from the second gateway.

The priority of each rule between the first MEP and the second MEP. When the first MEP communicates with the second MEP, there are multiple communication rules between them, and each rule corresponds to a priority. In order to improve communication efficiency, the first gateway will prioritize the implementation of rules with higher priority. For example, in the case of high network load, the first gateway will preferentially forward the data packets corresponding to the rules with higher priority.

After sending the first configuration information to the first gateway, the first MEP sends an Internet Security Protocol (IPsec, Internet Protocol Security) policy to the first gateway. The IPsec policy includes but is not limited to the encryption algorithm, key and message transmission mode used in the message transmission process. Based on the IPsec policy, a secure channel for data transmission can be established between the first gateway and the second gateway.

By specifically setting the configuration for communicating with the second MEP in the first configuration information, a data transmission channel can be established between the first gateway and the second gateway, realizing wide-area interconnection between the first MEP and the second MEP.

In this embodiment of the application, the UE sends a first request to the first system to request access to the second system, and the first system forwards the first request to the second device directly connected to the second system through the directly connected first device , so that the second system returns a first response to the UE based on the first request forwarded by the second device, and the first response carries the DNN of the second system for accessing the second system, so that the UE wants to access the second system In the case of two systems, the DNN corresponding to the second system can be obtained through the first system, and there is no need to manually configure the DNN of the second system that needs to be accessed, thereby improving the efficiency of the UE in obtaining the DNN corresponding to other systems, and also improving the UE's access to other systems s efficiency. And by setting the first device and the second device, the wide-area interconnection and intelligent routing functions between different systems are realized.

The specific process is to forward the first response to the second gateway, forward the first response to the first gateway through the second gateway, forward the first response to the first MEP through the first gateway, and return the first response through the first MEP to UE.

The UE needs to obtain the DNN corresponding to the second MEP before it can access the second MEP, so the first response returned by the second MEP carries the DNN of the second MEP.
