Method and system for D2D service charging

Abstract

The invention discloses a method and system for device to device (D2D) service charging. The charging method comprises the following steps that: an eNB sends an instant minimization-of-drive-test (MDT) configuration message to a D2D terminal, wherein a D2D charging indication is carried by the instant MDT configuration message; and the D2D terminal collects D2D charging information according to the instant MDT configuration message and sends the information to the eNB by an MDT charging report. In addition, the invention also provides a charging system for D2D services. According to the technical scheme provided by the invention, D2D service charging is realized by utilizing an MDT way.

Description

technical field [0001] The present invention relates to a wireless communication system, in particular to a charging method and system for a D2D service. Background technique [0002] In the evolution of mobile networks, mobile networks increasingly show the characteristics of broadband networks. With the widespread use of smart phones, media data streams are transmitted more and more frequently in mobile networks. Particularly, as social applications and location-based communication applications become more and more popular, the data traffic in the same area (that is, under the same base station, within the range of adjacent base stations) is increasing. These data flows need to detour to the public data network gateway of the core network, such as the gateway GPRS support node (GGSN, Gateway GPRS Support Node) or packet data gateway (P-GW, Public Data Network-Gateway), which greatly increases the backhaul bandwidth requirements , which increases the delay of IP communica...

AI Technical Summary

Problems solved by technology

In order to cope with the growing demand of IP data traffic, operators must add more public data network gateways, but the average monthly fee for each user is showing a downward trend, which also makes the investment and income of operators more and more unbalanced

[0004] In addition, due to the large number of applications of proximity business, for example, providing location-based friend search and communication, such as launching Facebook, Foursquare, etc., discovery of game players in proximity, game matchmaking with game players in proximity, specific venues The discovery and push of commercial advertisements, such as the transfer of football tickets, communication between IoT terminals, etc., even if the UE communicates in a small area, the IP data packet must be detoured to the public data network gateway located on the upper layer, and then sent to the Destination UE, thus causing detours of IP data flow

For the communication between UEs in the adjacent area, the industry has proposed a WIFI-like direct connection communication technology between adjacent UEs. Two UEs that are physically adjacent, such as two UEs within a range of 1Km, use the operator's spectrum resources. Through the burst pulse technology of increasing power, and the broadcast mechanism similar to WIFI to realize mutual discovery, and establish point-to-point direct wireless communication, realize the device-to-device (D2D, Device to Device) of this point-to-point direct wireless communication For services, UEs using D2D services can communicate directly, and the communication process does not need to go through the core network, so operators cannot obtain the service type, service establishment times, and service usage of D2D services, so the billing system cannot perceive the use of D2D services The basic billing information such as transmission traffic and duration, etc., makes it impossible for operators to accurately bill D2D services

[0005] To sum up, in the direct connection communication technology of the related technology, the D2D service uses the spectrum resources of the operator, but the operator cannot use the existing technology to charge the D2D service, so the operator hopes to provide a solution for charging the D2D service method
