The invention relates to the technical field of Internet of Things communication, discloses an Internet of Things multi-Android client state synchronization method, and solves the problems of poor state consistency, high back-end dependence, large delay and insufficient compatibility in the prior art. According to the scheme, the method comprises the steps that after a client completes initialization, MQTT connection with a rear end is established, an MQTT state message pushed by the rear end is monitored, after the message is received, equipment state information is obtained through analysis, local state cache and a UI interface are updated, meanwhile, the client serves as a distribution node, a UDP synchronization message containing the equipment state and the IP of the distribution node is established, and the UDP synchronization message is sent to the client. The UDP synchronization message is broadcasted to the local area network, other clients in the local area network receive the UDP synchronization message and then verify whether the distribution node IP is the client in the local area network, if the verification is passed, the message is analyzed, the state updating timestamp and the local cache timestamp are compared, and the local state cache and the UI interface are updated only when the state updating timestamp is larger.

The application relates to the technical field of communication, in particular to a 5G local area network communication method and device, a 5G local area network access equipment and a program product. The method comprises the following steps: a first session establishment request and a second session establishment request are sent to a 5G core network; a session policy returned by the 5G core network is received; a first virtual network interface and a second virtual network interface are created and configured inside the 5G local area network access equipment; two-layer communication data from a local area network device or sent to the local area network device is transmitted through the first virtual network interface and a first PDU session; three-layer IP communication data from a remote operation and maintenance end or sent to the remote operation and maintenance end is transmitted through the second virtual network interface and a second PDU session; wherein a logical isolation policy is configured between the first virtual network interface and the second virtual network interface. The method can effectively reduce the hardware cost and power consumption, is easy to deploy, the radio frequency interference is easy to control, and the interlayer communication is not easy to conflict.
