BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication service, and more particularly, to a mobile communication service providing a mobile communication service, which is based on an area for monitoring user location information in an LTE (Long Term Evolution) / EPC (Evolved Packet Core) network including an EUTRAN (Evolved Universal Terrestrial Radio Access Network) A location-based PCC control method and system in a mobile communication system suitable for performing PCC control, and a packet data network gateway apparatus for location-based PCC control.

A 3rd Generation Partnership Project (3GPP) mobile communication system based on WCDMA (Wideband Code Division Multiple Access) radio access technology is widely deployed all over the world. HSDPA (High Speed Downlink Packet Access), which can be defined as the first evolutionary phase of WCDMA, provides 3GPP mobile communication system with highly competitive wireless access technology in the mid-term future.

However, as the requirements and expectations of users and operators continue to increase and competition for developing wireless access technologies continues, there is a need to evolve new technologies in 3GPP mobile communication systems in order to gain competitiveness in the future. Reduced cost per bit, increased service availability, the use of flexible frequency bands, simple structure and open interfaces, and proper power consumption of terminals are becoming a requirement. In addition, prevention of unnecessary latency at the network node and efficient use of network resources can also promote the technology evolution in 3GPP.

In 3GPP Release 8, a network architecture called EPC is described as one of mobile communication systems for meeting the above-mentioned requirements. EPC is a set of network nodes for 3GPP LTE (Long Term Evolution) system. The EPC supports the Evolved UMTS Terrestrial Radio Access Network (EUTRAN), which is an evolved RAN, by evolving the core network of the existing 3GPP system architecture. In addition, in order to increase the efficiency of the packet network, The network structure is simplified. A wireless communication system including EPC and EUTRAN is called an evolved packet system (EPS).

Next, as another user plane entity, the Serving-GW is a mobility anchor for mobility between 3GPP accesses (E-UTRAN, UTRAN, GERAN). Serving-GW interworks with eNodeB and S1-U interface as session control and user plane node that handles payload traffic according to the established session and supports Inter LTE / 3GPP handoff .

Next, the MME is a control plane entity responsible for mobility management of UEs moving between different EUTRAN eNodeBs and also for session management.

The HLR / HSS 10 can be collectively referred to as a subscriber server as a home location register and a home subscriber server, and is a network node including a database including subscriber information on a wireless communication system, And location-related data.

The eNB 102 is an EUTRAN access type base station equipment and can perform functions such as RF transmission and transmission and reception, signal strength and quality measurement, baseband signal processing, and channel card resource management.

The NB 104 is a base station equipment of the UTRAN access method and can perform functions such as RF transmission and transmission and reception, signal strength and quality measurement, baseband signal processing, and channel card resource management.

The MME 106 is an EUTRAN access-type mobile communication exchange for signal control between the eNB 102 and a Serving-GW 110, which will be described later. The MME 106 is used to route data received from the UE 100 And manage subscriber information and mobility of UE 100, session management, idle subscriber management, paging, subscriber authentication, and the like.

The MME 106 transmits a Modify Bearer Request (MBR) message to the Serving-GW 110 according to the location information change of the UE 100, and transmits a Modify Bearer Answer (MBA) Request) message, the UE 100 can provide the communication service through the modified bearer. At this time, the MBR message may include ECGI information as user location information.

The SGSN 108 is a UTRAN-access mobile switching center that determines where to route the incoming data from the UE 100 and controls the mobility management of the subscriber information and the UE 100, session management, Paging, and subscriber authentication functions.

Serving-GW 110 is a serving gateway device that manages the mobility of UE 100 between eNB 102 and second eNB, between 3GPP network and EUTRAN, and handles payload traffic according to a set session A session control function can be performed. In addition, the Serving-GW 110 interworks with the eNB 102, supports handover between the LTE network and the LTE network / 3GPP, sets an EPS bearer with the PDN-GW 112, tunneling to the PDN-GW 112, and transmits the MBR message delivered from the MME 106 to the PDN-GW 112.

The PDN-GW 112 is a packet data network gateway device that assigns an IP of the UE 100 and performs session control in cooperation with the PDN 1 and the Non-3GPP network. The PDN-GW 112 includes a Serving-GW 110 and a PDN (1) and routing information, and can perform tunneling and IP routing functions. In addition, the PDN-GW 112 may be responsible for delivering PDUs to the Serving-GW 110 and the PDN 1.

The PDN-GW 112 may store ECGI information of the monitored area. The ECGI information can be reported to the PCRF 114 via the trigger setting for previously stored ECGI information.

If the MBR message is received from the Serving-GW 110, it is checked whether the MBRI message is matched with the previously stored ECGI information based on the ECGI information included in the MBR message. Only the matching ECGI information is transmitted to the PCRF 114 ) Can perform the ECGI change report. However, unmatched ECGI information is not reported to the PCRF 114 and can be discarded.

The OCS 116 is an on-line billing processing device, and can receive a billing information of a subscriber requiring real-time billing information, and can provide a credit management function such as a limit service.

The OFCS 118 collects the billing information generated by the PDN-GW 112 and processes it into billing data requested by the billing system and transmits the billing data.

The PCRF 114 is a charging policy rule processing apparatus capable of performing communication policies and charging processing in a communication network by providing dynamic QoS and charging rules according to a service data flow .

When the CCR 114 receives a CCR (Credit Control Request) message from the PDN-GW 112, the PCRF 114 can determine whether the UE 100 has changed its location based on the ECGI value included in the CCR message.

Based on this, it is possible to enable a more detailed location-based service of the ECGI unit, which is smaller than the eNB 102. In particular, the location based service for ECGI of the specific eNB 102, . ≪ / RTI >

2 is a flowchart illustrating a location-based PCC control procedure in a mobile communication system according to an embodiment of the present invention.

Referring to FIG. 2, in step 200, the eNB 102 first establishes a connection with the MME 106 in response to a connection request of the UE 100. FIG. The MME 106 performs authentication with the UE 100 according to the connection request of the eNB 102 and can confirm the location information of the UE 100, for example, the ECGI information. The RNC 110 performs radio resource control (RRC) connection between the UE 100 and the eNB 102 and establishes a session between the MME 106 and the Serving-GW 110 and the PDN- 100 to transmit and receive data.

Thereafter, the user of the UE 100 moves and is located in a place having a different ECGI value. That is, the ECGI may be a smaller area unit than the eNodeB, so, for example, one university area may be divided into a plurality of ECGI units. In this case, the eNB 102 confirms the changed position, that is, the changed ECGI through the paging with the UE 100, and the corresponding information is transmitted to the MME 106 through reconnection setting or the like.

In step 202, the MME 106 transmits a bearer modification request to the Serving-GW 110 through an MBR (Modify Bearer Request) message including the changed ECGI information of the UE 100, And transmits the MBR message to the PDN-GW 112.

In step 206, the PDN-GW 112 checks the changed ECGI information of the UE 100 in the MBR message received from the Serving-GW 110, and confirms whether the ECGI information matches with the previously stored ECGI information.

In step 208, a CCR (Credit Control Request) update message is transmitted to the PCRF 114 to report on the ECGI change of the UE 100 in step 208. In step 210, the PCRF 114 transmits a credit control answer / response (CCA) message, which is a response message to the CCR update message, and receives the message.

The PDN-GW 112 having received the CCA message transmits a Modify Bearer Answer / Response (MBA) message in response to the MBR message to the Serving-GW 110 in step 212, and the Serving- MBA message to the MME 106, thereby performing PCC control according to the changed ECGI of the UE 100 through this operation procedure.

The triggering method for each ECGI in the PDN-GW 112 will be described in detail with reference to FIG. 3 to FIG.

3 is a schematic block diagram of a packet data network gateway apparatus for location-based PCC control in a mobile communication system according to an embodiment of the present invention.

3, the PDN-GW 112 serving as a packet data network gateway apparatus includes a service processing unit 300, a receiving unit 302, a message generating unit 304, an ECGI list DB 306, a transmitting unit 308, .

Specifically, the receiving unit 302 can receive the MBR message from the Serving-GW 110 and receive the CCA message from the PCRF 114. [

The service processing unit 300 can check the ECGI information in the MBR message transmitted from the receiving unit 302 and check whether the trigger is set by comparing the ECGI information with previously stored ECGI information.

For example, information on whether or not a trigger is set for each ECGI can be expressed as shown in Table 1 below.

ECGI value What you will do Explanation 1234AB34DDF REPORT Report ECGI changes in PCRF 1234AB34DDA REPORT Report ECGI changes in PCRF Default DISCARD ECGI values not set are not reported to the PCRF

That is, since the trigger is set for each ECGI as shown in Table 1, it can be determined whether or not the ECGI information of the UE 100 is matched with the stored ECGI information.

Therefore, the service processing unit 300 can perform the ECGI change report to the PCRF 114 only for the ECGI information matched with the previously stored ECGI information, and can discard the unmatched ECGI information without reporting it to the PCRF 114 .

The message generating unit 304 may generate a bearer setup request and an IP allocation request message to be delivered to the Serving-GW 110 under the control of the service processing unit 300. The MME 106 may generate a bearer setup request and an IP allocation request message, And generate a deletion request message for the call connection request. And generate an MBA message in response to the CCR message reported to the PCRF 114 and the MBR message of the Serving-GW 110. [

The ECGI list DB 306 may store ECGI information of a region to be monitored and may include trigger setting information for ECGI information stored as shown in Table 1 above.

The transmitting unit 308 transmits a message generated through the message generating unit 304 to the MME 106, and can transmit a message such as a bearer setup request, an IP allocation request, and a call deletion request. Also, the CCR message can be transmitted to the PCRF 114 and the MBS message can be transmitted in response to the MBR message of the Serving-GW 110 under the control of the service processing unit 300.

4 is a flowchart illustrating an operation procedure of a packet data network gateway apparatus for location-based PCC control in a mobile communication system according to an embodiment of the present invention.

Referring to FIG. 4, in step 400, the PDN-GW 114 receives an MBR message from the Serving-GW 110.

Since the MBR message includes the ECGI information which is changed position information of the UE 100, the ECGI information is compared with the ECGI information stored in the ECGI repository DB 306 in step 402, .

If it is determined that the previously stored ECGI information matches the ECGI information of the UE 100 in step 404, the UE 100 proceeds to step 406 to generate a CCR update message including the ECGI change of the UE 100 To the PCRF 114 and reported. If the CCA message is received from the PCRF in response to the CCR update message in step 408, the MBS message is transmitted to the Serving-GW 110 in step 410.

In step 404, it is determined whether ECGI information previously stored matches the ECGI information of the UE 100. If the ECGI information is not matched, it is determined that the ECGI is not set. Therefore, the ECGI proceeds to step 412 and reports to the PCRF 114 The corresponding ECGI information is discarded.

As described above, the embodiment of the present invention monitors location information of a user in an LTE / EPC network and receives location information of a user terminal device. The location information of the received user terminal device is monitored in the PDN-GW , The location information is reported to the PCRF.
