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.

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.
