Method, apparatus and system for information transmission

The present invention provides a method, an apparatus and a system for information transmission. A first base station may identify, according to indication information, global information and local information from uplink information transmitted by a user device: if the indication information indicates that the uplink information contains global information, the first base station uploads the global information to a core network device, and if the indication information indicates that the uplink information contains local information, the first base station transmits the local information to a neighboring base station directly such that the neighboring base station can transmit the local information downlink to user devices in cells that the neighboring base station covers, thereby shortening the transmission path of data information, reducing the transmission delay of data information, improving the transmission speed of data transmission. Since it is unnecessary to forward the local information by means of a core network, the transmission delay of the local information is reduced, thereby reducing the delay of a communication system. In addition, the load of the core network can also be reduced in cases where the local information is not processed by the core network.
