TABLE 1
| Content providing method and apparatus | Latitude and longitude coordinates |
| ContextA | (x1，y1) |
| ContextB | (x2，y2) |
| ContextC | (x3，y3) |
| ...... | ...... |

For example, the first terminal acquires Cell information Info-Cell2 of a mobile communication network Cell in which it is located, and takes the Cell information Info-Cell2 of the mobile communication network Cell in which it is located as its own first location information.
Step 207: the method comprises the steps that a first terminal sends an acquisition request message to a content server, wherein the acquisition request message carries first position information of the first terminal;
for example, the first terminal sends an acquisition request message to the content server, where the acquisition request message carries first location information Info-Cell2 of the first terminal, and the first location information of the first terminal is Cell information of a mobile communication network Cell where the first terminal is located.
Step 208: the content server receives the acquisition request message and acquires the latitude and longitude coordinates of the first terminal according to the first position information of the first terminal;
specifically, if the first location information of the first terminal is the longitude and latitude coordinates of the location of the first terminal, the content server directly extracts the longitude and latitude coordinates of the first terminal from the acquisition request message;
if the first position information of the first terminal is the cell information of the mobile communication network cell in which the first terminal is currently located, the content server acquires the longitude and latitude coordinates of the first terminal according to the cell information of the mobile communication network cell in which the first terminal is currently located;
and if the first position information of the first terminal is the gateway address of the mobile communication network accessed by the first terminal, the content server acquires the longitude and latitude coordinates of the first terminal according to the gateway address of the mobile communication network accessed by the first terminal.

Step 209: the content server calculates the distance between the second terminal corresponding to each content in the content storage platform and the first terminal according to the longitude and latitude coordinates of the first terminal and the longitude and latitude coordinates of the second terminal corresponding to each inner space in the content storage platform;
specifically, the content server scans each piece of content in the content storage platform, acquires the longitude and latitude coordinates of the second terminal corresponding to the scanned content from the content storage platform, and calculates the distance between the second terminal corresponding to the scanned content and the first terminal according to the longitude and latitude coordinates of the first terminal and the longitude and latitude coordinates of the second terminal corresponding to the scanned content.
For example, scanning is started from a first piece of content of the content storage platform shown in table 1, when ContextA is scanned, longitude and latitude coordinates (x1, y1) of the second terminal corresponding to the scanned content ContextA are obtained, and according to the longitude and latitude coordinates (x0, y0) of the first terminal and the longitude and latitude coordinates (x1, y1) of the second terminal corresponding to the scanned content ContextA, the distance between the first terminal and the second terminal corresponding to the scanned content ContextA is calculated asWhen the content ContextB is scanned, acquiring longitude and latitude coordinates (x2, y2) of a second terminal corresponding to the scanned content ContextB, and calculating the distance between the first terminal and the second terminal corresponding to the scanned content ContextB as the distance between the first terminal and the second terminal corresponding to the scanned content ContextB according to the longitude and latitude coordinates (x0, y0) of the first terminal and the longitude and latitude coordinates (x2, y2) of the second terminal corresponding to the scanned content ContextBIn the same manner as described above, the distance between the second terminal and the first terminal corresponding to each content in the content information table shown in table 1 is calculated.
Step 210: the content server acquires a content information list from the content information table according to the distance between the first terminal and the second terminal corresponding to each content, wherein the content information list comprises the content and the distance between the first terminal and the second terminal corresponding to the content;
specifically, the content server selects, from the content storage platform, a content whose distance between the second terminal and the first terminal is smaller than a preset distance, or selects, from the content storage platform, a preset number of contents whose distance between the publisher and the recipient is the smallest, and combines the selected content and the distance between the second terminal and the first terminal corresponding to the selected content into a content information list.
The content server can select the content of which the distance between the second terminal and the first terminal is smaller than the preset distance from the content information table, so that the content issued by a publisher near the receiver or the content issued by a publisher in the same city as the receiver can be acquired through the preset distance; for example, assuming that the preset distance is 1000 meters, the content issued by the publisher whose receiver is within the range of 1000 meters can be acquired, so that the content issued by the publisher near the receiver is acquired; for another example, assuming that the preset distance is 10 kilometers, the content issued by the publisher whose receiver is within the range of 10 kilometers can be acquired, so that the content issued by the publisher located in the same city as the receiver is acquired.
Step 211: the content server processes the content in the content information list, and then sends an acquisition response message to the first terminal, wherein the acquisition response message carries the acquired content information list.
The content server sorts the content in the content information list according to the distance between the second terminal and the first terminal, then sends an acquisition response message to the first terminal, the acquisition response message carries the acquired content information list, the first terminal receives the acquisition response message sent by the content server, and after the first terminal receives the acquisition response message, the content information list carried by the acquisition response message can be displayed to a receiver.
