US 8,477,640 B2 · Method, apparatus and system for information transmission

Abstract

A method, an apparatus and a system for information transmission are provided. 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.

Dependent claims

An information transmission method, comprising:

receiving, by a first user equipment, a beacon message broadcasted by a second user equipment, wherein the beacon message comprising a second information identification stored in the second user equipment;
detecting, by the first user equipment, that the second user equipment has update information through detecting that the second information identification is not identical to a first information identification stored in the first user equipment, wherein each of the first and second information identifications is used to distinguish update information;
establishing, by the first user equipment, a temporary connection with the second user equipment;
and
receiving, by the first user equipment, the update information from the second user equipment through the temporary connection;
wherein the first and second user equipments are wireless communication devices.

3 more elements

An information transmission method, comprising:

broadcasting, by a second user equipment, a beacon message, wherein the beacon message comprising a second information identification stored in the second user equipment;
sending, by the second user equipment, update information to a first user equipment through a temporary connection established when the first user equipment receives the beacon message and detects that the second information identification in the beacon message is not identical to a first information identification stored in the first user equipment, wherein each of the first and second information identifications is used to distinguish update information, and
the first and second user equipments are wireless communication devices.

A user equipment, which is a second wireless communication device, comprising:

a message broadcast unit, configured to periodically generate a beacon message, wherein the beacon message comprising a second information identification stored in the second wireless communication device;
and
a wireless transceiver unit, is configured to send out the beacon message generated by the message broadcast unit, and further to send update information to a first wireless communication device through a temporary connection established when the first wireless communication device receives the beacon message generated by the message broadcast unit and detects that the second information identification in the beacon message is not identical to a first information identification stored in the first user equipment.
