Claim:
1. A method for prompting a signal blind area in advance, applied to a mobile terminal, comprising: locating the mobile terminal, and acquiring current location information of the mobile terminal; determining distances between a current location of the mobile terminal and locations of various blind area boundary points recorded in a blind area list; and when one or more of the distances are less than or equal to a preset first blind area distance threshold, sending a prompt of approaching the signal blind area to a user; the method further comprising: deleting blind area boundary point location information from the blind area list; wherein the step of deleting the blind area boundary point location information from the blind area list comprises: when detecting that intensity of a wireless signal currently received by the mobile terminal is greater than or equal to a preset blind area signal intensity threshold, and distances between the current location of the mobile terminal and locations of one or more blind area boundary points recorded in the blind area list are less than or equal to a preset second blind area distance threshold, deleting records of blind area boundary points with distances between the blind area boundary points and the current location of the mobile terminal being less than or equal to the preset second blind area distance threshold from the blind area list; wherein the second blind area distance threshold is less than the first blind area distance threshold.
