The method includes the following steps. A second user equipment receives update information issued by a wireless access point (AP). The second user equipment is located within a coverage area of the wireless AP. After detecting that the second user equipment has the update information, a first user equipment establishes a connection with the second user equipment and obtains the update information from the second user equipment. The first user equipment is located outside the coverage area of the wireless AP. In the present invention, the user equipment can update the information without additionally increasing the transmit powers of the wireless AP and the user equipments when located outside the coverage area of the wireless AP, and thus the interference to other equipments is minimized."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, apparatus and system for information transmission","description":"A method, an apparatus and a system for information transmission are provided.
