Among them, the MME handles the signal control between the eNodeB serving as the base station and the SGW, and determines the routing for the transmission data of the mobile communication terminal device. The MME performs paging message distribution to the eNodeB, non-access spectrum (NAS) signaling, intra-network handover control, tracking area list management, and the like. In addition, the MME performs selection of SGW and PGW, selection and change of MME for handover, terminal authentication, and the like.

The SGW is a user plane node that performs session control for processing payload traffic according to a set session. It interfaces with eNodeB and S1-U interface, supports handover in 3GPP, sets up PGW and EPS bearer, and delivers PDU (Packet Data Unit) using tunneling.

The PGW is a user plane node that assigns an IP address of a mobile communication terminal device and performs session control in cooperation with an external Internet network and a non-3GPP network. Maintains SGW and external network and routing information for packet service, and performs tunneling and IP routing functions.

In recent years, an LTE-A (LTE Advanced) service has been commercialized, which focuses on using a plurality of LTE bands as one band using a technique called Carrier Aggregation (hereinafter referred to as "CA"). The LTE-A service supports a communication speed as high as an increased bandwidth due to the frequency aggregation technology, and an LTE-A modem must be installed in a mobile communication terminal device.

3 is a flowchart illustrating a method of transmitting a terminal information according to an embodiment of the present invention.

As shown in the figure, the method of transmitting a terminal information according to an embodiment of the present invention includes steps S301 to S305 of receiving a bearer modification request message according to location information change or state information change of a mobile communication terminal apparatus, .

The method further includes a step (S307) of determining a change event of the location information or the state information based on the received bearer modification request message.

In addition, a step S309 of generating a message including identification information on a change event of the position information or the change event of the state information according to a result of the change event discrimination, and transmitting the generated message according to the call processing path .

The method of claim 1, further comprising the steps of: S311 and S313 re-establishing predetermined service quality-related information based on the service quality-related information included in the message received through the call processing path, And sending a modification response message (S315).

Hereinafter, a process of transmitting UE information between nodes in a mobile communication system to which the UE information transmitting apparatus 200 according to an embodiment of the present invention is applied will be described with reference to FIG. 1 to FIG. According to the present invention, a mobile communication system can efficiently operate radio resources by selectively applying CA services according to types of data services.

First, in the PGW 160, service quality related information serving as a reference for providing a service to the mobile communication terminal devices 111 to 116 such as a QoS class identifier (QCI) is preset (S301).

Then, a change event of the state information is generated (S303), in which the state information is changed, such as a change event of the location information in which the location information of the mobile communication terminal apparatuses 111 to 116 is changed or an idle state to an active state, The SGW 150 transmits a modify bearer request message to the PGW 160 (S305). In this bearer modification request message, the location information change and the state information change of the mobile communication terminal units 111 to 116 are separated.

Then, the message receiving unit 210 of the terminal information transmitting apparatus 200 receives the bearer modification request message from the SGW 150 according to the change of the location information or the change of the state information of the mobile communication terminal apparatuses 111 to 116.

In addition, the event determination unit 220 of the terminal information transmission apparatus 200 determines whether a change event of the location information is generated or a change event of the state information is generated based on the received bearer modification request message (S307 ).

The message generating unit 230 of the terminal information transmitting apparatus 200 transmits a message including identification information of a change event of the location information or a change event of the state information according to the result of the determination by the event determination unit 220 And the message transmission unit 240 of the terminal information transmission apparatus 200 transmits the message generated by the message generation unit 230 according to the call processing path (S309).

For example, the message generating unit 230 may generate a credit control request-update (CCR-U) message as a service policy request message including identification information on a change event of location information or a change event of the status information, The message transmission unit 240 transmits the generated CCR-U message to the PCRF 170. [

Here, the PGW 160 receives the bearer modification request message from the SGW 150, and then transmits the CCR-U message to the PCRF 170 in the related art. However, the CCR-U message does not include information related to the change of the location information and status information of the mobile communication terminal units 111 to 116, I could not tell whether the location was changed or the state was changed.

However, according to the embodiment of the present invention, since the CCR-U message includes the identification information of the change event of the location information or the change event of the status information by the mobile communication terminal devices 111 to 116, Based on such identification information, it is possible to discriminate whether the position of the mobile communication terminal units 111 to 116 has been changed or the state has been changed. For example, the message generator 230 inserts an event trigger field into the CCR-U message only when a change event of the location information is generated, and when a change event of the state information occurs, The event trigger field is not inserted so that the change event of the position information and the change event of the status information can be distinguished.

Next, the PCRF 170 receives a message including the identification information of the change event of the location information of the mobile communication terminal units 111 to 116 or the change event of the status information, that is, the CCR-U message, from the PGW 160 do. Then, information on the service type of the data packet can be received from the DPI 190.

Then, the PCRF 170 can discriminate whether the location information change event has occurred or the state information change event has occurred in the mobile communication terminal devices 111 to 116. The PCRF 170 determines service quality-related information for each type of data service for the mobile communication terminals 111 to 116 and transmits a message including the determined service quality-related information to the PGW 160 (S311) . For example, the PCRF 170 may send a Credit Control Answer-Update (CCA-U) message to the PGW 160 as a service policy response message including service quality related information. For example, the QCF value may be included in the service quality-related information included in the CCA-U message. The PCRF 170 may classify the QCI value to initialize the service policy for the change event of the status information, For the change event, the last assigned policy can be applied.

Next, the PGW 160 re-sets the pre-set service quality related information based on the service quality related information included in the message received from the PCRF 170 through the call processing path (S313). In addition, as a response to the bearer modification request message received in step S305, the bearer modification response message (modify bearer answer) is transmitted to the SGW 150 (S315).

In addition, the PGW 160 transmits a message including the service quality related information determined by the PCRF 170 to the SGW 150, and the SGW 150 can transmit the service quality related information to the eNodeB 100. Then, the eNodeB 100 adjusts the scheduling for each type of data service to the mobile communication terminal units 111 to 116 based on the service quality-related information, selectively applies the CA service for each type of data service, Can be efficiently operated.
