CLAIMS What is claimed is: 1. A method of controlling charging data record generation in a node, comprising: a first step of the data service node generating a charging data record (S-CDR) according to data usage for a session-set terminal; Determining whether the data usage of the session-set terminal is equal to or greater than a predetermined reference value; If the result of the determination is greater than or equal to a predetermined reference value, returning to the first step, and if less than the reference value, stopping generation of a billing data record (S-CDR) and returning to the second step; It is achieved by the charging data record generation control method in a packet data service network comprising a.

Details of the above object and technical configuration of the present invention and the resulting effects thereof will be more clearly understood from the following detailed description based on the accompanying drawings.

First, Figure 1 is a block diagram of a packet data service network for explaining the present invention.

As shown, the packet data service network to which the charging data record generation control method of the present invention is applied is an asynchronous IMT-2000 network, and is a node B (node-B) 110 for wireless section communication with the mobile communication terminal 100. ), A wireless network controller (RNC) 120 for controlling the Node B, a home location register (HLR) 130 that manages subscriber information and additional service information, and is connected and moved between the wireless network controller 120 and the IP network. A data service node (SGSN) 140 that monitors the location of a communication terminal and performs security technology and access control functions, and a data service gateway node (GGSN) as a gateway for being connected to the data service node 140 to provide packet data services. , 150).

In order to perform charging for data service usage of the mobile communication terminal 100 in the packet data service network, the data service node 140 and the data service gateway node 150 are respectively charged data records (G-CDR, S). -CDR is generated and delivered to the billing gateway 160, the billing gateway 160 is billing data (G-CDR) received from the data service gateway node 150 and billing received from the data service node 140 Data (S-CDR) is delivered to the billing server that handles billing.

Meanwhile, the data service node 140 and the data service gateway node 150 generate charging data records according to data usage time or data usage. In the former embodiment of the present invention, the terminal does not use data for a long time. If it is not in the shaded area or stops the generation of billing data record, and in the latter case the generation of billing data record is stopped if the data usage of the terminal is less than a certain reference amount.

That is, in the present invention, when the user does not use data, the charging traffic is controlled in two ways.

First, when the billing data record is generated in the data service node 140 and the data service gateway node 150 over time, the terminal 100 sets the data service node 140 and the data service gateway node 150. If it is determined that the data is not used for a long time or the session is lost to the shadowed area, the wireless network controller 120 releases the radio resource. In this manner, the wireless network controller 120 releases the radio resource. It is called a preservation state.

That is, when the wireless network controller 120 recognizes that the terminal should be switched to the retention state, the wireless network controller 120 transmits parameter information corresponding to the transition condition to the retention state to the data service node 140, and the data service node 140 transmits the parameter information. This parameter information is checked to request the release of radio resources to the radio network controller 120, and then generation of the billing data record (S-CDR) is stopped.

In this case, since the data service gateway node 150 cannot know that the terminal is in the preservation state, the data service node 140 is in the preservation state of the current terminal through the option field of the PDP context update request message to the data service gateway node 150. It transmits information indicating that the data service gateway node 150 receives the information, and also stops the generation of the billing data record (G-CDR).

Second, when the data service node 140 and the data service gateway node 150 generate the charging data record according to the data usage, the data service node 140 and the data service gateway node 150 respectively use the data usage for charging. With reference value of, if the terminal does not transmit and receive data traffic above the reference value, generation of charging data record is stopped.

The generation control method of the charging data record in the packet data service network will be described in more detail with reference to FIGS. 2 to 4.

First, FIG. 2 is a flowchart illustrating a session creation process in a packet data service network.

As shown, when the data service node 140 receives an PDP context activation request message from the mobile communication terminal 100 to receive a packet data service (S101), the data service gateway node ( In step S102, a PDP context creation request message (Create PDP Context Request) is transmitted.

Next, as the data service gateway node 150 responds to the PDP context creation request from the data service node 140 (Create PDP Context Response) (S103), the data service node 140 is connected to the terminal 100. If the PDP context activation request from the (Activate PDP Context Accept) is accepted (S104), and thus a session is generated between the terminal 100, the data service node 140 and the data service gateway node 150 (S105). The data service node 140 and the data service gateway node 150 generate charging data S-CDR and G-CDR according to time or data usage, respectively (S106-1 and S106-2).

Next, FIG. 3 is a flowchart illustrating a charging data record generation control method according to an embodiment of the present invention, which illustrates a process of controlling generation of charging data as radio resources are released when charging data is generated over time. .

As shown, when a session is generated between the terminal 100, the radio network controller 120, the data service node 140, and the data service gateway node 150 according to the process described with reference to FIG. 2 (S201), the data service Node 140 and data service gateway node 150 start generating charging data records, respectively (S202-1, S202-2).

Subsequently, when the wireless network controller 120 recognizes that the packet data service use state of the terminal 100 does not perform data transmission / reception, which is a transition condition to a preservation state (S203), the data service In operation S204, the node 140 transmits information indicating that the terminal is to be switched to a preservation state.

Here, the state in which data transmission and reception are not performed includes a case in which the terminal 100 does not use a data service for a long time and a case where the terminal 100 is in a shaded area.

Next, when the data service node 140 receives information indicating that the session-set terminal 100 is to be switched to a retention state from the wireless network controller 120, the data service node 140 releases the radio resource to the wireless network controller 120. In operation S205, the radio network controller 120 releases the radio resources allocated to the terminal 100 (S206).

In addition, the data service node 140 transmits to the data service gateway node 150 the PDP context update request message including information indicating that the terminal is in a preservation state (S207), and a charging data record (S-CDR). The generation of is stopped (S208-1).

In addition, the data service gateway node 150 recognizes that the terminal is in a preservation state according to the information included in the PDP context update request message received from the data service node 140, and determines that the billing data record (G-CDR) of the billing data record (G-CDR). The generation is stopped (S208-2).

Next, FIG. 4 is a flowchart illustrating a charging data record generation control method according to another embodiment of the present invention, wherein the data service node 140 and the data service gateway node 150 generate charging data records according to data usage, respectively. In this case, the generation of the charging data record is controlled according to the process illustrated in FIG. 4.

That is, since the process of controlling the generation of the charging data record using the data usage is equally applied to the data service node 140 and the data service gateway node 150, the process of FIG. 4 is described below for convenience of description. It will be described as the execution process in 140).

As shown, the data service node 140 generating a charging data record (S-CDR) according to the data usage with respect to the terminal 100 having session set up (S301) (S302) is the data of the session set terminal 100 It is determined whether the amount of usage is greater than or equal to a predetermined reference value (S303).

As a result of the determination, the data service node 140 continuously generates the charging data record when the reference value is greater than or equal to a predetermined reference value (S302). ).

In the case of controlling the generation of the billing data record according to the data usage, since the generation of the billing data record should be resumed when the data usage exceeds the reference value again, the data service node 140 continues even after the generation of the billing data record is stopped. The method determines whether the data usage is equal to or greater than the reference value (S303), and if it is determined to be equal to or greater than the reference value, the generation of the billing data record is restarted (S302).

As those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features, the embodiments described above should be understood as illustrative and not restrictive in all aspects. Should be. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.
