7. The positioning method according to claim 6, further comprising sending the positioning request response message to the second user equipment, wherein the positioning request response message comprises the positioning authorization condition.

8. The positioning method according to claim 1, wherein positioning, by the first user equipment, the second user equipment under the positioning authorization condition, and wherein obtaining the location information of the second user equipment comprises receiving, by the first user equipment, geographical location information of the second user equipment that is sent by the second user equipment according to the positioning authorization condition.

9. The positioning method according to claim 8, further comprising:

sending, by the first user equipment, a request message comprising the geographical location information to a server, wherein the request message is used to request the server to send map identifier location information obtained after matching the geographical location information and map information of the server; and

receiving, by the first user equipment, a request response message sent by the server, wherein the request response message comprises the map identifier location information after matching the geographical location information and the map information of the server.

10. The positioning method according to claim 9, further comprising:

performing, by the first user equipment, matching on the geographical location information according to local map information; and

determining, by the first user equipment, the map identifier location information of the second user equipment.

11. The positioning method according to claim 1, wherein positioning, by the first user equipment, the second user equipment under the positioning authorization condition, and wherein obtaining the location information of the second user equipment comprises:

sending, by the first user equipment, a request message comprising an identifier information of the second user equipment to a server, wherein the request message is used to request the location information of the second user equipment;

receiving a request response message sent by the server, wherein the request response message comprises map identifier location information obtained after matching geographical location information of the second user equipment and map information of the server; and
