The invention relates to the field of intensive network management, and discloses an SNMP management method, device and system based on MQTT, and the method comprises the steps: supporting the marking of information carrying a link resource, a communication resource and an enterprise private network OLT equipment ID through expanding a community of an SNMP protocol; the expanded SNMP protocol is packaged into an MQTT (Message Queuing Telemetry Transport) protocol; the MQTT protocol is expanded by increasing the hierarchy of publishing the theme so as to support information interaction. According to the invention, by expanding the MQTT protocol, SNMP management of multiple networking environments such as private-to-public and private-to-private can be realized.

According to the enterprise-dedicated Internet of Things special line detection system and method provided by the invention, a novel Internet of Things special line detection architecture is designed, so that the Internet of Things special line state can be rapidly and automatically detected without depending on cooperation of an operator-side Internet element and a network management system, and the detection efficiency is improved. Therefore, the enterprise private network Internet of Things application guarantee level based on the operator Internet of Things private line is improved.

The invention relates to the technical field of wireless communication and terminals, in particular to a communication system, method and device and a medium. The communication system provided by the embodiment of the invention comprises a public network gateway deployed in an operator public network and a user plane data network gateway PGW-U deployed in an enterprise private network, the public network gateway comprises a service gateway SGW and a data intercommunication gateway; by deploying the first S5 / S8 interface in the data intercommunication gateway, the access and data interaction of the 4G terminal under the condition that the operator public network SGW and the enterprise private network PGW-U are safely isolated are realized, and the communication security is improved.

The present disclosure provides a method and device for limiting user terminal access to a UPF, a storage medium and an electronic device, and relates to the technical field of mobile communication. The method comprises: receiving a session establishment request forwarded by an SMF, wherein the session establishment request contains an identifier of a user terminal; querying whether the identifier of the user terminal exists in a whitelist of the UPF according to the session establishment request, wherein the whitelist contains identifiers of a plurality of user terminals stored in advance; and establishing a session between the UPF and the user terminal if the identifier exists. The present disclosure sinks the control point of user access to the edge UPF, which is dedicated to enterprise private networks, and limits user access by setting a whitelist in the edge UPF, thereby limiting user terminal access to the UPF while being applicable to SMFs in a large network position in a neighbor mode.

The present disclosure proposes a virtual private dial-up network access method, a network side system, a system and a storage medium, and relates to the field of mobile communication technology. A virtual private dial-up network access method disclosed in the present disclosure includes: the access and mobility management function AMF receives a VPDN access request from a user, and the VPDN access request includes the data network name DNN of the target VPDN, the account number and key of the target VPDN; the AMF obtains the target session management function SMF supporting the VPDN service through the network storage function NRF, and sends a session management context request to the target SMF; the SMF selects the user plane function UPF supporting the VPDN service to establish a session according to the session management context request, so as to establish a tunnel with the target VPDN through the UPF. Through such a method, the support of 5G network element equipment for VPDN service characteristics can be improved, and the convenience of VPDN access can be improved; there is no need to change the existing enterprise private network equipment on the client side, which is conducive to rapid deployment and promotion of application.

The present application provides an access control method and a communication device based on SIM card information. The method includes: a firewall in an enterprise private network receives an access request from a terminal device, and the access request includes the IP address of the terminal device; the firewall determines the SIM card information corresponding to the IP address, and then performs access control on the access request according to the access control policy associated with the SIM card information. Since the SIM card information is bound to each terminal device, based on the SIM card information, differentiated and refined access control can be implemented for the terminal devices within the enterprise private network.

This disclosure relates to the field of centralized network management, and discloses an SNMP management method, apparatus, and system based on MQTT. The method includes: extending the SNMP protocol community to support tagging that carries information including link resources, communication resources, and the enterprise private network OLT device ID; encapsulating the extended SNMP protocol into the MQTT protocol; and extending the MQTT protocol by adding layers to the published topic to support information exchange. This disclosure, by extending the MQTT protocol, can realize SNMP management in various networking environments, such as private-to-public and private-to-private.

This invention provides a satellite network connection method, apparatus, device, and storage medium, relating to the field of satellite communications. It includes initiating a wireless connection request to a satellite via a public channel to allocate a dedicated channel; receiving configuration information sent by the satellite and configuring the dedicated channel according to the configuration information; sending wireless connection establishment completion information via the dedicated channel for identifying the enterprise through the vehicle terminal identification code and initiating an identity authentication request to the corresponding enterprise cloud platform; receiving authentication and encryption commands; sending them to the enterprise cloud platform, along with identity authentication information, and establishing a dedicated communication tunnel with the enterprise cloud platform. This can support the construction of enterprise private networks independent of operator networks and can also solve the problem of vehicle-to-everything (V2X) services when a vehicle SIM card is invalid for some reason. In particular, when vehicles are sold overseas, if a foreign SIM card is installed, the car manufacturer can still conduct V2X services normally, such as software upgrades and fault diagnosis.

A method performed by a secure network abstraction function (SNAF) entity for operating a private network is provided. The method includes receiving a first control message from a first network entity, and performing a control operation on a second network entity on the basis of the first control message, wherein the first network entity is a control center included in the private network, and the second network entity is at least one of a session management function (SMF) entity, an access and mobility management function (AMF) entity, or a user plane function (UPF) entity, and wherein the first network entity and the SNAF entity are connected via an application programming interface (API), and the SNAF entity and the second network entity are connected via a service-based interface (SBI).
