摘要

A method for rejoining a network after network disconnection of a mobile terminal and related devices are provided. The method includes: a gateway determining whether to disconnect from a target mobile terminal; if yes, feeding back network disconnection information of the target mobile terminal to a server; receiving a supplementary broadcast frame instruction sent by the server; and the gateway sending a supplementary broadcast frame according to the supplementary broadcast frame instruction.

說明書

Sending the supplementary broadcast frame instruction to the gateway device and the at least one other gateway device within the first preset distance range relative to the gateway device includes:

determining a predicted movement direction of the target mobile terminal according to the movement track; and

sending the supplementary broadcast frame instruction to the gateway device and other gateway devices which are within the first preset distance range and in the predicted movement direction relative to the gateway device.

For example, referring to FIG. 1, assuming that the target mobile terminal uploads the locating information once at each gray dot, the movement track (the track of gray dots in FIG. 1) of the target mobile terminal may be determined according to the locating information. Therefore, it can be predicted that the predicted movement direction of the target mobile terminal is from the gateway m to the gateway k. In this case, the gateway k may be used as an object for receiving the supplementary broadcast frame instruction, while the gateway n may not be used as an object for receiving the supplementary broadcast frame instruction.
