Abstract: Disclosed in the present invention are a permanent-magnet magnetic levitation rail transit control system and method based on 5G communication technology. The system comprises: an intelligent control center, a 5G communication platform, a train security system, an Internet of things monitoring system, and a passenger service system. In the present invention, targeted at the problem of being difficult to ensure barrier-free transmission of signals even by means of beamforming technology due to high moving speed of a permanent-magnet magnetic levitation rail transit system and small coverage of 5G base stations, a multi-connectivity scheme is used, and the intelligent control center selects two 5G base stations for signal transmission at the same time depending on distribution of 5G base stations along a line, wherein one 5G base station is the current closest base station, and the other 5G base station is the next base station to be approached.

Abstract: The present invention provides a method for establishing an enterprise group and a corresponding apparatus. According to an example, an IM application server may determine, according to a received join-group request for adding a first user to an inside group, whether identity information of the first user matches attribute information of the inside group. If the identity information of the first user matches the attribute information of the inside group, the server may add the first user to the inside group, and send a first notification message to a client corresponding to the first user. If the identity information of the first user does not match the attribute information of the inside group, the server may create an inter-enterprise group including the first user and all members of the inside group, and send a second notification message to the client corresponding to the first user.

Abstract: The present disclosure discloses a task management method based on an instant message, a client and a server. According to an example of the method, the client displays instant messages in a group on a message display interface. When a task conversion operation for any one of the instant messages is obtained on the message display interface, the client sends the task conversion operation for the instant message to the server. When receiving the task conversion operation, the server converts the instant message into a target task to be processed and sends the target task to the client. When receiving the target task from the server, the client displays the target task on a task display interface.
