The present invention relates to a mobile communication service, and in particular, location-based based on an area for monitoring user location information in a Long Term Evolution (LTE) / Evolved Packet Core (EPC) network including an Evolved Universal Terrestrial Radio Access Network (EUTRAN). A method and system for location-based PCC control in a mobile communication system suitable for performing PCC control, and a packet data network gateway device for location-based PCC control.

3rd Generation Partnership Project (3GPP) mobile communication systems based on Wideband Code Division Multiple Access (WCDMA) radio access technology are widely deployed around 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 interface, and adequate power consumption of the terminal are demanding requirements. In addition, the prevention of unnecessary latency in the network node and the 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 the mobile communication systems for meeting the aforementioned requirements. EPC is a set of network nodes for 3GPP LTE (Long Term Evolution) system. EPC has evolved the core network of the existing 3GPP system architecture to support Evolved UMTS Terrestrial Radio Access Network (EUTRAN), which is an evolved RAN, and to improve the efficiency of packet networks. It has an efficient network structure that simplifies. A wireless communication system including an EPC and an EUTRAN is called an evolved packet system (EPS).

The EPC network is divided into three logical entities: PDN-GW (Packet Data Network Gateway), Serving-GW (Serving GW), and MME (Mobility Management Entity).

First, in the user plane, the PDN-GW is a global mobility anchor for mobility between 3GPP access technology and non-3GPP access technology (such as CDMA2000, WiMAX, or WIFI) and a gateway to an external network. Protocol is a session control and user plane that allocates protocols and interworks with external Internet networks and non-3GPP networks, maintains routing information with Serving-GW and external networks for packet services, and provides tunneling and IP Has routing function.

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

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

The MME 106 is an EUTRAN access mobile communication switching station in charge of signal control between the eNB 102 and Serving-GW 110, which will be described later. The MME 106 may route data received from the UE 100 to somewhere. It may be responsible for the subscriber information and mobility management, session management, idle subscriber management, paging, subscriber authentication function and the like of the subscriber information and the UE (100).

The MME 106 transmits a bearer modification request (MBR) message to the Serving-GW 110 according to a change in the location information of the UE 100, thereby modifying a bearer response (MBA: Modify Bearer Answer (MBA). When a request)) message is received, a communication service may be provided to the UE 100 through the modified bearer. In this case, the MBR message may include ECGI information as user location information.

The SGSN 108 is a UTRAN access mobile communication switching center that determines where to route incoming data from the UE 100, and manages subscriber information and mobility of the UE 100, session management, idle subscriber management, It can play the role of paging, subscriber authentication function, etc.

Serving-GW 110 is a serving gateway device that manages the mobility of the UE 100 between the eNB 102 and the second eNB, between the 3GPP network and the EUTRAN, and processes payload traffic according to an established session. Session control function can be performed. In addition, Serving-GW 110 interworks with eNB 102, supports handover within LTE network or between LTE network / 3GPP, sets up PDN-GW 112 and EPS bearer, and tunneling ( A packet data unit (PDU) may be delivered using tunneling, and an MBR message transmitted from the MME 106 may be transmitted to the PDN-GW 112.

The PDN-GW 112 is a packet data network gateway device for allocating IP of the UE 100 and controlling sessions interworking with the PDN 1 and the Non-3GPP network. The PDN-GW 112 serves the Serving-GW 110 and the PDN for packet services. Maintains routing information and performs tunneling and IP routing functions. In addition, the PDN-GW 112 may serve to deliver the PDU to the Serving-GW 110 and the PDN 1.

The PDN-GW 112 may prestore ECGI information of a region to be monitored. In addition, ECGI change reporting may be performed to the PCRF 114 through the trigger setting on the prestored ECGI information.

In response to receiving the MBR message from the Serving-GW 110, the ECF information is checked based on the ECGI information included in the MBR message to check whether there is a match, and only for the matching ECGI information, the PCRF 114. ) Can be used to report ECGI changes. However, ECGI information that does not match is not reported to the PCRF 114 and may be discarded.

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

The OFCS 118 is a billing processing device that collects billing information generated by the PDN-GW 112, processes the billing system into billing data required by the billing system, and transmits the billing data. The OFCS 118 may accommodate various billing protocols such as Radius, Diameter, and GTPP to provide a unified billing (BS) interface.

The PCRF 114 is a charging policy rule processing apparatus. The PCRF 114 may provide dynamic QoS and charging rules according to a service data flow to perform communication policy and charging processing in a communication network. .

Accordingly, when the PCRF 114 receives a credit control request (CCR) message from the PDN-GW 112, the PCRF 114 may check whether the location of the user UE 100 is changed based on the ECGI value included in the CCR message.

Based on this, it is possible to enable a more granular location-based service of the ECGI unit, which is a smaller area unit than the eNB 102, and in particular, the location-based service for the ECGI of the specific eNB 102 rather than the location-based service for all the ECGI. Can be enabled.

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 performs connection establishment with the MME 106 for a connection request of the UE 100. In addition, the MME 106 may perform authentication with the UE 100 according to the connection request of the eNB 102, so as to confirm location information of the UE 100, for example, ECGI information. In addition, the UE (through the radio resource control (RRC) connection process between the UE 100 and the eNB 102 and the session establishment between the MME 106 and the Serving-GW 110 and the PDN-GW 112). Data transmission / reception at 100).

Thereafter, the UE 100 user moves and is located where the UE 100 has a different ECGI value. That is, since the ECGI may be a smaller unit of area than the eNodeB, for example, one university area may be divided into a plurality of ECGI units. In this case, the eNB 102 checks the changed location, that is, the changed ECGI through paging with the UE 100, and transmits the corresponding information to the MME 106 through reconnection establishment.

Accordingly, the MME 106 transmits a bearer modification request to the Serving-GW 110 through a Modify Bearer Request (MBR) message including changed ECGI information of the UE 100 in step 202, and the Serving-GW 110. The MBR message is transmitted 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 checks whether the UE matches the previously stored ECGI information.

In this case, in step 208, a credit control request (CCR) update message is transmitted to the PCRF 114 to perform reporting according to the ECGI change of the UE 100. In step 210, the PCRF 114 transmits a CCA (Credit Control Answer / Response) message, which is a response message to the CCR update message, to receive it.

After receiving the CCA message, the PDN-GW 112 transmits a Modify Bearer Answer / Response (MBA) message to the Serving-GW 110 in response to the MBR message in step 212, and the Serving-GW 110 sends the message. By transmitting the MBA message to the MME 106, PCC control according to the changed ECGI of the UE 100 is performed through this operation procedure.

The triggering method for each ECGI in the PDN-GW 112 will be described in detail with reference to FIGS. 3 to 4.

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

Referring to FIG. 3, the PDN-GW 112, which is a packet data network gateway device, includes a service processor 300, a receiver 302, a message generator 304, an ECGI list DB 306, a transmitter 308, and the like. It may include.

In detail, the receiver 302 may receive an MBR message from the Serving-GW 110 and may receive a CCA message from the PCRF 114.

The service processor 300 may check the ECGI information in the MBR message transmitted from the receiver 302 and check whether the trigger is set by comparing the ECGI information with previously stored ECGI information.

For example, trigger setting information for each ECGI may be represented as shown in Table 1 below.

ECGI value What to do Explanation 1234AB34DDF REPORT Report ECGI Changes in PCRF 1234AB34DDA REPORT Report ECGI Changes in PCRF Default DISCARD Do not report to the PCRF for ECGI values not set

That is, since the trigger is set for each ECGI as shown in Table 1, it is possible to determine whether to match the ECGI information of the UE 100 with previously stored ECGI information.

Accordingly, the service processing unit 300 may perform ECGI change report on the PCRF 114 only for ECGI information matching the previously stored ECGI information, and discard the mismatched ECGI information without reporting it to the PCRF 114. .

The message generator 304 may generate a bearer setup request and an IP allocation request message to be transmitted to the Serving-GW 110 under the control of the service processor 300, and the MME 106 may perform an ongoing call or a new call of a specific UE. A delete request message for the call connection request can be generated. The MBA message may be generated 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 the ECGI information of the region to be monitored, and may also include trigger setting information for the stored ECGI information as shown in Table 1 above.

The transmitter 308 transmits a message generated through the message generator 304 to the MME 106, and may transmit a message such as a bearer setup request, an IP allocation request, and a call deletion request. In addition, the CCR message may be transmitted to the PCRF 114, and under the control of the service processor 300, the MCR message may be transmitted in response to the MBR message of the Serving-GW 110.

4 is a flowchart illustrating an operation procedure of a packet data network gateway device 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 the changed location information of the UE 100, in step 402, whether there is an ECGI in which a trigger is set by comparing the corresponding ECGI information with the ECGI information previously stored in the ECGI reform DB 306. Will be checked.

In step 404, if it is determined whether matching ECGI information is stored with the ECGI information of the UE 100 in step 404, the process proceeds to step 406 to generate a CCR update message including whether to change the ECGI of the UE 100 The report is sent to the PCRF 114. Thereafter, when the CCA message is received in response to the CCR update message from the PCRF in step 408, the MBA message is transmitted to the Serving-GW 110 in step 410.

On the other hand, in step 404 it is determined whether the match between the pre-stored ECGI information and the ECGI information of the UE 100 is not matched, the trigger is not set ECGI, and proceeds to step 412 and reports to the PCRF 114 The ECGI information is discarded.

As described above, in the embodiment of the present invention, the location information of the user terminal device is received by monitoring the location information of the user in the LTE / EPC network, and the location information of the received user terminal device is an area monitored by the PDN-GW. In this case, location information is reported by PCRF.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but is capable of various modifications within the scope of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the scope of the appended claims, and equivalents thereof.

Even if it is possible to prevent the need to report the location information of all changed user terminal devices, it is suitable for removing unnecessary operation procedure between the PCRF and the PDN-GW.
