the first terminal broadcasts the preset information including the first location via radio frequency, in other embodiments, such as: the first terminal tries to broadcast the information directly to the second terminal equipment held by other team members which can receive the information and meet the receiving conditions through limited distance transmission modes such as radio frequency, Bluetooth and the like.
Step 304, the server sends the preset information including the first position to the second terminal;
and the server sends the received preset information comprising the first position to the second terminal. Accordingly, the second terminal receives the preset information including the first location. For the second terminal that can't directly receive above-mentioned preset information through limited distance transmission methods such as radio frequency, bluetooth, will send the preset information including first position to the second terminal through the server, for example: and pushing the message leaving information, the position information, the message leaving time and other related information of the team leader to second terminal equipment held by the team members according with the team forming conditions.

Such as: an application program on second terminal equipment acquires first position information of a first terminal, acquires current position information, namely second position information, of the second terminal through a GPS, and judges whether preset information playing conditions are met or not by calculating the distance between the second position and the first position.
Step 307, if the distance is greater than the preset threshold, the second terminal obtains the moving speed of the second terminal, calculates the moving time T according to the moving speed and the distance,
when the moving time of the second terminal is T/N, the second terminal recalculates the distance between the second position of the second terminal and the first position of the first terminal;
if the distance between the second position of the second terminal and the first position of the first terminal is greater than the preset threshold, the second terminal obtains the moving speed of the second terminal, and the moving speed can be obtained through a map SDK on the second terminal or through setting a time interval and obtaining the moving distance in the time interval, and the moving speed is calculated. And calculating the time for the second terminal to move to the first position according to the acquired moving speed and the distance, and recalculating the distance between the current position of the second terminal and the first position of the first terminal by the second terminal when the moving time of the second terminal is T/N. And if the distance is still larger than the preset threshold value, repeating the steps until the distance between the second position of the second terminal and the first position of the first terminal is not larger than the preset threshold value.
In this embodiment, when the moving time is T/N, the second terminal recalculates the distance between the second position of the second terminal and the first position of the first terminal. Wherein N is any natural number greater than 1. In other embodiments, other algorithms may be employed, including but not limited to: and acquiring the moving speed of the second terminal in real time, and calculating the distance between the second position of the second terminal and the first position of the first terminal in real time.

And if the distance between the second position of the second terminal and the first position of the first terminal is not greater than the preset threshold value, the second terminal plays preset information including the first position. In other embodiments, such as: when the second terminal held by the team member is already in the message information range including the first position sent by the team leader, the message information is automatically activated and is displayed to the team member in a corresponding mode. The showing mode includes, but is not limited to, the player turning left or right at the first position, etc.
In summary, in the location-based information broadcasting method provided in this embodiment, the first terminal records the preset information including the first location, and sends the preset information including the first location to the server, the server sends the preset information including the first location to the second terminal, and the second terminal calculates the distance between the second location of the second terminal and the first location of the first terminal, and if the distance is not greater than the preset threshold, the second terminal broadcasts the preset information including the first location; the problem that the team leader can not find a way or can not walk a branch when communicating a route with the team members in real time in the existing team traveling is solved; the technical effects that team members can accurately acquire route information and efficient and safe group traveling is achieved. The first terminal and/or the second terminal directly broadcast the preset information to second terminal equipment held by other team members which can receive the preset information and meet the receiving conditions through limited distance transmission modes such as radio frequency, Bluetooth and the like; the problem of at wired or wireless network signal disappearance such as mobile network or wifi or relatively poor environment, can also realize the effect of the high-efficient safe trip of group more thoroughly through limited distance transmission mode broadcast route information such as radio frequency, bluetooth.
