Charging method and device for off-line point-to-point opposite communication

Abstract

The charge method for off-line P2P communication in user terminal comprises: communicating off-line with another terminal user, recording and sending the communication information to communication network for charge by the network.. Thereby, even there is no UTRAN, the charge can be executed normally.

Description

field of invention [0001] The present invention relates to a communication network, in particular to a charging method and device for off-line point-to-point peer-to-peer (P2P: Peer to Peer) communication. technical background [0002] In a traditional cellular mobile communication system, a user terminal must pass through a base station to communicate with another user terminal. figure 1 It shows the traditional communication mode in the TD-SCDMA system, user terminals UE1 and UE2 exchange information through the universal mobile communication system terrestrial radio access network (UTRAN) composed of base station (Node B) and radio network controller (RNC). However, when two user terminals residing in the same cell are very close to each other, it should be a more reasonable method to use direct communication, which is the so-called point-to-point peer-to-peer communication, or P2P for short. P2P communication is typically applied in a TDD wireless system where the uplin...

Problems solved by technology

However, when the UE performs offline P2P communication, since the UE performing offline P2P communication is completely out of the control of UTRAN, UTRAN cannot directly obtain the necessary information required for P2P communication charging in the way of traditional communication mode or online P2P communication mode , especially when offline P2P communication occurs outside the wireless network coverage area, synchronous billing is more difficult
