Abstract:
1. A method for managing shared information which is generated between first and second communication devices in a communication system, comprising: generating the shared information at each of the first and second communication devices; transmitting identifying information from the first communication device to the second communication device, wherein the identifying information identifies a piece of the shared information generated in the first communication device; making an association between same pieces of the shared information generated at respective ones of the first and second communication devices based on the identifying information; and storing associated pieces of the shared information at respective ones of the first and second communication devices, wherein the shared information is generated at each of the first and second communication devices by: transmitting original information in first data processing units from one of the first and second communication devices to the other communication device by using a low power channel and a normal power channel that defines beginning and ending points of separate frames of the original information being transmitted; and generating the shared information in second data processing units at each of the first and second communication devices based on information which was received in the first data processing units by the other communication device by using a normal power channel, wherein the shared information in the second data processing units is stored in a first storage section, wherein the associated pieces of the shared information at respective ones of the first and second communication devices are stored in a second storage section.
