An electronic shelf label communication system, comprising a processor, a plurality of wireless access points and a plurality of electronic shelf label groups, wherein each of the wireless access points is corresponding to the plurality of electronic shelf label groups, and each of the electronic shelf label groups comprises a plurality of electronic shelf labels; the processor is configured to send update data comprising a plurality of update data packages to the wireless access point corresponding to the electronic shelf label group where the electronic shelf label requiring data update is located; the wireless access point is configured to: send, upon receipt of the update data sent by the processor, a group wakeup message to the electronic shelf label requiring data update, wherein the group wakeup message comprises a plurality of countdown durations for receiving the update data by the electronic shelf label requiring data update; and send, after the electronic shelf label requiring data update wakes up according to each of the countdown durations for receiving the update data, the unsent update data packages corresponding to the electronic shelf label to the electronic shelf labels requiring data update in a same electronic shelf label group simultaneously, until all of the update data packages corresponding to the electronic shelf label are sent, wherein the adjacent update data packages, which are sent by the wireless access point, are sent to different electronic shelf labels, and there is a countdown duration for receiving the update data between different batches of update data packages of the same electronic shelf label; the electronic shelf label is configured to: wake up periodically, receive the group wakeup message and obtain the plurality of countdown durations for receiving the update data; and wake up again according to each of the countdown durations for receiving the update data, and receive the unreceived update data packages once, until all of the update data packages are received. each of the wireless access points is corresponding to the plurality of electronic shelf label groups, and each of the electronic shelf label groups comprises a plurality of electronic shelf labels;
