A transmission system includes: a transmission management system and a fee management system. The transmission management system manages participation time information using a given transmission terminal. The fee management system manages participation fee information. The transmission management system includes a transmission unit that transmits the participation time information to the fee management system. The fee management system includes: a user management unit that manages user identification information and terminal identification information in a manner linked; a reception unit that receives the participation time information transmitted from the transmission management system; a participation time calculation unit that calculates a total participation time of conversation; a participation fee calculation unit that calculates a participation fee; and a participation fee summing unit that refers to the user management unit, sums up participation fees of each transmission terminal, and calculates a total participation fee for each user.

A method and apparatus are configured to recognize mobile terminals positioned within a coverage area for short range communication with a user-specific device, wherein each mobile terminal comprises identification information for the user-specific device. The method and the apparatus provide a customized service corresponding to at least one of the mobile terminals.

A communication system includes: a relay device including: a storage unit configured to store terminal specification information for specifying the third terminal associated with the second terminal, and a first communication control unit configured to connect the third terminal to the first network if an authentication control unit authenticates the terminal authentication information; one or more first terminals connected to a first network; a second terminal connectable to the first network and including a second communication control unit configured to transmit the relay-device specification information and the terminal authentication information to the third terminal through the second network if receiving the relay-device specification information and the terminal authentication information from the relay device; and a third terminal connectable to a second network and including a third communication control unit configured to transmit the terminal authentication information to the relay device through the second network.

Systems and methods for generating charging data records for commercial group-based messages broadcast by a telecommunications network to a group of subscribers are provided. In one aspect, a network element of a telecommunications network is configured to identify individual user devices that successfully received and processed a message that was broadcast over the telecommunications network to a target group of user devices. The identification of the particular devices in the target group of devices that successfully received and processed the broadcast message is used for generating sender based charging or sender-plus-receiver based charging data records for the subscribers of the telecommunication network.
