Abstract

A method for sending a message is provided. The method includes: detecting whether a user is located in a target place; if the user is not located in the target place, detecting whether an entrance of the target place is opened; and if the entrance of the target place is opened, sending a prompt message to a device carried by the user.

First claim

What is claimed is:

1. A method for sending a prompt message to a wearable device of a user to indicate a status of an entrance among a plurality of entrances of a target place, comprising:
detecting, by a server device, whether the user is located in the target place based on a first message sent from the wearable device carried by the user and a pre-stored message corresponding to the target place, the first message indicating a location of the user and the pre-stored message indicating a location of the target place, wherein the server device determines whether the user is located in the target place based on whether the two locations are identical;
if it is determined that the user is not located in the target place, detecting, by the server device, whether an entrance of the target place is opened; and
if it is determined that the entrance of the target place is opened, sending, by the server device, the prompt message to the wearable device to indicate the state of the entrance to the user via the wearable device;
wherein the server device determines whether the user is located in the target place based on the first message and the pre-stored message corresponding to the target place comprises:
when the first message is a first device list and the pre-stored message is a second device list, detecting whether the user is located in the target place based on a similarity between the first device list and the second device list, the first device list being a list of devices which are connected in a first network covering a place where the user is currently located, and the second device list being a list of devices which are connected in a second network covering the target place; and
when the first message is a first location message of the wearable device of the user and the pre-stored message is a second location message of the target place, detecting whether the user is located in the target place based on the first location message and the second location message; and

wherein when the first location message is a geographic position message of the wearable device and the second location message is a geographic position message of the target place, detecting, by the server device, whether a distance between the wearable device and the target place is less than a predetermined threshold; and
when the first location message is an Internet Protocol (IP) address of the wearable device and the second location message is an address of a network segment corresponding to the target place, detecting, by the server device, whether the IP address of the wearable device is contained in the address of the network segment.

2. The method of claim 1 , wherein detecting whether the user is located in the target place further comprises:
receiving, by the server device, a second message sent from a device in the target place, and
detecting, by the server device, whether the user is located in the target place based on the second message.

3. The method of claim 2 , wherein detecting, by the server device, whether the user is located in the target place based on the second message comprises:
when the second message is a movement-indicating message, detecting whether the user is moving in the target place during a preset time period based on the movement-indicating message; and
when the second message is a monitoring message obtained from monitoring of the target place, detecting whether the user leaves the target place based on the monitoring message.

4. The method of claim 3 , wherein detecting whether an entrance of the target place is opened comprises:
receiving state messages sent from entrance-opening sensors of the target place, each of the entrance-opening sensors being associated with a corresponding entrance of the plurality of the entrances;
detecting whether one of the state messages indicates that the corresponding entrance, of the target place is in an opened state; and
if it is detected that one of the state messages indicates that the corresponding entrance of the target place is in the opened state, determining that the corresponding entrance of the target place is opened.

5. The method of claim 1 , wherein detecting, by the server device, whether the entrance among the plurality of the entrances of the target place is opened comprises:
receiving state messages sent from entrance-opening sensors of the target place, each of the entrance-opening sensors being associated with a corresponding entrance of the plurality of the entrances;
detecting whether one of the state messages indicates that the corresponding entrance of the target place is in an opened state; and
if it is detected that one of the state messages indicates that the corresponding entrance of the target place is in the opened state, determining that the corresponding entrance of the target place is opened.

6. The method of claim 2 , wherein detecting, by the server device, whether the entrance among the plurality of the entrances of the target place is opened comprises:
receiving state messages sent from entrance-opening sensors of the target place, each of the entrance-opening sensors being associated with a corresponding entrance of the plurality of the entrances;
detecting whether one of the state messages indicates that the corresponding entrance of the target place is in an opened state; and
if it is detected that one of the state messages indicates that the corresponding entrance of the target place is in the opened state, determining that the corresponding entrance of the target place is opened.

7. A server device for sending a prompt message to a wearable device of a user to indicate a status of an entrance among a plurality of entrances of a target place, comprising:
a processor; and
a memory for storing instructions executable by the processor; wherein the processor is configured to perform:
detecting whether the user is located in the target place based on a first message sent from the wearable device carried by the user and a pre-stored message corresponding to the target place, the first message indicating a location of the user and the pre-stored message indicating a location of the target place, wherein the server device determines whether the user is located in the target place based on whether the two locations are identical;
if it is determined that the user is not located in the target place, detecting whether an entrance of the target place is opened; and
if it is determined that the entrance of the target place is opened, sending the prompt message to the wearable device to indicate the state of the entrance to the user via the wearable device;
wherein the server device determines whether the user is located in the target place based on the first message and the pre-stored message corresponding to the target place comprises:
when the first message is a first device list and the pre-stored message is a second device list, detecting whether the user is located in the target place based on a similarity between the first device list and the second device list, the first device list being a list of devices which are connected in a first network covering a place where the user is currently located, and the second device list being a list of devices which are connected in a second network covering the target place; and
when the first message is a first location message of the wearable device of the user and the pre-stored message is a second location message of the target place, detecting whether the user is located in the target place based on the first location message and the second location message; and

wherein when the first location message is a geographic position message of the wearable device and the second location message is a geographic position message of
