## Abstract

Embodiments herein provide a method and system of reporting a charging information for a Device-to-Device (D2D) communication established using a wireless network. The method includes recording by a first electronic device the charging information associated with a D2D communication session. The D2D communication session is established between the first electronic device and a second electronic device. Further, the method includes determining by the first electronic device whether the charging information meets charging criteria during the D2D communication session. The charging criteria are generated by a network node in a secure environment of the first electronic device. Further, the method includes reporting the charging information to the network node in the wireless network in response to determining that the charging information meets the charging criteria.

## Claims

### Claim 1

A method for reporting information by a first terminal in a communication system, the method comprising:
performing a device to device (D2D) communication with at least one second terminal when the at least one second terminal and the first terminal are out of coverage of any network node;
recording usage information according to the communication;
generating at least one usage information report from the recorded usage information based on a predetermined period;
identifying whether the first terminal returns to a coverage for a network node of the any network node; and
transmitting the generated at least one usage information report, when the first terminal returns to the coverage of the network node.
