Description

Charging method and system for D2D service

Technical Field

The present invention relates to wireless communication systems, and in particular, to a charging method and system for D2D service.

Background

In the evolution of mobile networks, mobile networks are increasingly showing the characteristics of broadband networks. With the wide application 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 popular, data traffic in the same area (i.e., under the same base station and in the range of nearby base stations) becomes larger. These Data flows all need to detour to a Public Data Network Gateway of the core Network, such as a Gateway GPRS Support Node (GGSN) or a packet Data Gateway (P-GW), which greatly increases the backhaul bandwidth requirement, increases the delay of IP communication, and also increases the burden of the Public Data Network Gateway.

As mobile networks become more broadband, increasing IP data traffic also places higher demands on public data network gateways of the core network. In order to cope with the increasing demand of IP data traffic, the operators must add more public data network gateways, but monthly charges of each user are in a downward trend, and the investment and income of the operators are unbalanced more and more.

In addition, due to the large number of applications of proximity services, for example, providing location-based friend search and communication, such as launching Facebook, Foursquare, etc., discovery of game players in proximity locations, game pairing with game players in proximity locations, discovery and pushing of commercial advertisements in specific places, such as football field ticket assignment, inter-terminal communication of the internet of things, etc., even if the UE communicates in a small range, IP packets must bypass to a public data network gateway located at an upper layer and then be sent to the destination UE, thereby causing the bypass phenomenon of IP data flow. For the communication between UEs in the neighboring area, the industry proposes a WIFI-like direct communication technology between neighboring UEs, where two UEs that are physically adjacent, such as two UEs within 1Km range, utilize the spectrum resources of the operator, mutual discovery is realized through a burst pulse technology for increasing power and a broadcasting mechanism similar to WIFI, and establishes point-to-point direct connection wireless communication, realizes Device-to-Device (D2D) services utilized by the point-to-point direct connection wireless communication, and the UEs utilizing the D2D services can directly communicate without passing through a core network, the operator cannot acquire the service type, service establishment times and service usage of the D2D service, therefore, the charging system cannot sense basic information of charging such as transmission flow, duration and the like of the service using D2D, so that an operator cannot accurately charge the service D2D.

In summary, in the direct connection communication technology of the related art, the D2D service utilizes the spectrum resource of the operator, but the operator cannot charge the D2D service by using the prior art, so the operator wants to provide a method for charging the D2D service.

Currently, in order to reduce the cost and complexity of manual Drive Test by using dedicated devices, the Third Generation Partnership project (3 GPP) organizes the Minimization of Drive Test (MDT) function in Release 10(Release-10) of Universal Terrestrial Radio Access Network (UTRAN) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN) systems. The UTRAN includes a base station (Node B) and a Radio Network Controller (RNC), and the corresponding Core Network (CN, Core Network) includes a Home Subscriber Server (HSS), a Mobile Switching Center (MSC), a Serving GPRS Support Node (SGSN), and the like. The E-UTRAN includes an evolved Node B (eNB), and the corresponding core network includes an HSS, a Mobile Management Entity (MME), and the like. The MDT function automatically collects measurement information using a User Equipment (UE), reports the measurement information to a Radio Access Network (RAN) through a Control Plane (Control Plane) signaling, and reports the measurement information to a Trace Collection Entity (TCE) of an Operation and maintenance system (OAM) through the RAN. The application scenarios of the MDT function mainly include coverage optimization, capacity optimization, mobility optimization, common channel parameter optimization and the like.

In the prior art, the MDT function supports signaling-based MDT (signaling-based MDT) and management-based MDT (management-based MDT). The signaling-based MDT activation process generally includes an OAM sending a message to an HSS to activate MDT measurement of a certain UE, the HSS sending MDT configuration information of the UE to an MME, the MME sending the MDT configuration information of the UE to an eNB, and the eNB finally sending the MDT configuration information to the UE. Signaling-based MDT typically specifies a UE with an International Mobile Subscriber Identity (IMSI) or an International Mobile Station Equipment Identity (IMEI), or adds regional information to limit the UE's selection. The management-based MDT activation procedure is typically an OAM sending message to the eNB to activate MDT measurements for certain UEs, selecting a UE by the eNB, and sending MDT configuration information to the selected UE.

In the prior art, the MDT function supports the UE to perform MDT measurement in a CONNECTED (CONNECTED) state, and MDT performed in the CONNECTED state is called immediate MDT (immediate MDT). Immediately, MDT means that the UE performs MDT measurement in a connection state according to MDT configuration information and reports the measurement information to the radio access network in time, and then reports the measurement information to the TCE through the radio access network. The UE may be configured with immediate MDT configuration information for guiding the UE to perform immediate MDT measurement and reporting. The MDT configuration information is configured by the network to the UE when the UE is in a connected state. The MDT configuration information is invalidated after the specified time is exceeded, and for immediate MDT configuration information, the MDT configuration information is also invalidated after the UE enters the idle state.

In the prior art, a flow of implementing signaling-based immediate MDT is shown in fig. 1, and the flow includes the following steps:

in step 101, the OAM sends an immediate MDT configuration message based on signaling to the core network, which is used to activate a specific UE to start MDT measurement (assuming that the UE is in a connected state at this time).

Step 102, the core network stores the immediate MDT configuration message of the UE.

Step 103, the core network sends the immediate MDT configuration message of the UE to the eNB.

Step 104, the eNB sends the immediate MDT configuration message of the UE to the UE.

And 105, after receiving the immediate MDT configuration message, the UE performs corresponding MDT measurement and report.

In step 106, the UE reports the MDT measurement report to the eNB through an MDT report (report) message.

In step 107, the eNB reports the received MDT measurement report to the TCE.

In the prior art, the implementation flow of management-based immediate MDT is shown in fig. 2, and the flow includes the following steps:

in step 201, the OAM sends an immediate MDT configuration message based on management to the eNB to activate some UEs to start MDT measurement.

In step 202, the eNB saves the MDT configuration message.

Step 203, when the eNB detects the UEs meeting the measurement condition, the eNB issues an MDT configuration message to the UEs.

And step 204, after receiving the MDT configuration message, the UE performs corresponding MDT measurement and report.

In step 205, the UE reports the MDT measurement report to the eNB through an MDT report message.

In step 206, the eNB sends a Cell traffic tracking (Cell traffic track) message to the core network through S1 connection (S1 connection), where the Cell traffic tracking message carries parameters such as a Tracking Recording Session Reference (TRSR), a tracking Reference (TR, track Reference), a serving Cell global identity (serving Cell CGI), and a tracking collection entity IP address (TCE IP address) related to the MDT report.

And step 207, the core network refers to the terminal identification information according to the parameters carried in the Cell traffic Trace message, and sends the found corresponding relation between the terminal identification and the TR and TRSR to the TCE.

In step 208, the eNB reports the received MDT measurement report to the TCE.

Step 209, after receiving the MDT measurement report reported by the eNB, the TCE obtains the terminal identifier according to the TR and TRSR therein and the corresponding relationship between the TR and TRSR received from the core network and the terminal identifier.
