Multi-cell information source generating and sending method and device for LTE signal shielding system

The invention discloses a multi-cell information source generating and sending method and a device for an LTE signal shielding system. The method comprises the steps of generating data according to the number of frequency points of a service base station in a shielding area; and setting that P frequency points and Q cells exist in the shielding area, if P is less than Q, generating a group of databy each frequency point, combining each group of data with a plurality of cell data, generating P groups of data corresponding to the Q cells in total, and transmitting the combined P groups of datathrough medium radio frequency processing. According to the information source generating and sending method and the device, data of multiple cells under one frequency point can be integrated, under the condition that multiple cells exist at one frequency point, the number of data needing to be generated by a shielding system can be reduced, the number of transmitting channels needed by the shielding system is reduced, and
