As shown in FIG. 2, the apparatus may be included in PGW (2) of SPGW in FIG. A setting unit 21, a second setting unit 22, a receiving unit 23, a comparing unit 24, an assigning unit 25, and a transmitting unit 26.

The first setting unit 21 is for setting the PDN type per APN according to the communication standard to one of IPv4, IPv6, and IPv4v6. For example, the first setting unit 21 sets the APN A to IPv6, the APN B to IPv4, Such as IPv4v6 or the like, in a table or the like.

The second setting unit 22 is for setting the PDN Type for the specific APN to one of IPv4 Preference and IPv6 Preference added separately from the PDN Type according to the communication standard of the first setting unit 21. For example, 1 setting unit 21 may change the IPv6 as the PDN Type set for the APN A to the IPv6 Preference or set the IPv4 Preference to the IPv4 Preference set as the PDN Type set for the APN B.

The receiving unit 23 is for receiving the PDN Type information of the IP requested to be allocated from the MME 3 through a CSR (Create Session Request) message received from the MME 3. For example, from the MME 3, (CSR) message transmitted in the CSR (Create Session Request) message and obtain the PDN Type information included in the received CSR (Create Session Request) message.

The comparing unit 24 compares the PDN Type of the first APN obtained from the CSR (Create Session Request) message with the corresponding APN of the APN-specific PDN Type set in the first and second setting units 22 through the receiver 23, The first APN obtained from the CSR (Create Session Request) message is the same as the specific APN set in the added PDN Type (i.e., IPv4 Preference or IPv6 Preference) of the second setting unit 22 (Hereinafter referred to as the first PDN Type) set in the second setting unit 22 and the PDN Type of the IP requested to be allocated from the MME 3 (hereinafter referred to as the second PDN Type) That is, the second PDN types obtained from the CSR (Create Session Request) message can be compared with each other through the receiver 23.

The assigning unit 25 is for assigning IP according to the comparison result of the comparing unit 24. For example, the assigning unit 25 can assign an IP as follows based on the IP assigning table of FIG.

For example, if the first PDN Type (indicating the PDN Type set in the first and second setting units) for the specific APN is IPv4 Preference and the second PDN Type (CSR PDN Type: obtained from the CSR message through the receiver) PDN Type) is IPv4, IPv6, or IPv4v6, IPs of IPv4, IPv6, or IPv4 can be allocated, respectively. This is in accordance with the IP allocation scheme added according to the present embodiment in addition to the communication standard.

As another example, if the first PDN Type (GW-setting) for a specific APN is an IPv6 Preference and the second PDN Type (CSR PDN Type) is IPv4, IPv6, or IPv4v6, an IP of IPv4, IPv6, or IPv6 is allocated . This is in accordance with the IP allocation scheme added according to the present embodiment in addition to the communication standard.

As another example, if the first PDN Type (GW-setting) for a specific APN is IPv4 and the second PDN Type (CSR PDN Type) is IPv4, IPv6, or IPv4v6, an IP of IPv4, Reject, or IPv4 is allocated . This is the same as the communication standard.

As another example, if the first PDN Type (GW-setting) for a specific APN is IPv6 and the second PDN Type (CSR PDN Type) is IPv4, IPv6, or IPv4v6, an IP of Reject, IPv6, or IPv6 is allocated . This is the same as the communication standard.

As another example, when the first PDN Type (GW-setting) for a specific APN is IPv4v6 and the second PDN Type (CSR PDN Type) is IPv4, IPv6, or IPv4v6, the IP of IPv4, IPv6, or IPv4v6 is allocated . This is the same as the communication standard.

The transmitting unit 26 includes an IP of the corresponding PDN Type allocated through the assigning unit 25 in a CSR (Create Session Response) message as a response message to a CSR (Create Session Request) message received via the receiving unit 23 And transmits it from the PGW 2 to the MME 3.

FIG. 3 is a flowchart of a method for allocating IP in the PGW of the LTE system according to the embodiment of the present invention, and is performed in the PGW (2) of FIG.

The PGW 2 sets the PDN Type for each APN to one of IPv4, IPv6 and IPv4v6 according to the communication standard through the first setting unit 21 (S301) The PDN Type is set to one of an IPv4 Preference and an IPv6 preference as a PDN Type separately added to the communication standard (S303).

Next, the PGW 2 receives the CSR (Create Session Request) message from the MME 3 (S305), and confirms the APN information included in the CSR (Create Session Request) message (S307).

If it is determined in step S307 that the corresponding APN corresponds to a specific APN having a GW-setting PDN type set in step S303, the GW-setting PDN Type (i.e., IPv4 Preference or IPv6 preference) (S309).

In step S309, if the GW-setting PDN Type additionally set in step S303 for a specific APN is IPv4 Preference and the PDN Type of the CSR message received in step S305 is IPv4, IPv6, or IPv4v6, the PGW (2) , IPv6, or IPv4.

If the PDN Type of the CSR message received in step S305 is IPv4, IPv6, or IPv4v6, the GW-setting PDN Type set in step S303 for the specific APN is IPv6 Preference in step S309 and the PGW (2) , IPv6, or IPv6.

On the other hand, if it is determined in step S307 that the corresponding APN corresponds to an APN having a GW-setting PDN type set according to the standard in step S301, the GW-setting PDN Type (i.e., IPv4, IPv6 , IPv4v6) (S311).

In step S311, if the GW-setting PDN Type set in accordance with the standard in step S301 is IPv4 and the PDN Type of the CSR message received in step S305 is IPv4, IPv6, or IPv4v6 for the corresponding APN You can assign IPv4, Reject (reject IP allocation), or IP of IPv4.

As another example, if the GW-setting PDN Type set according to the standard in step S301 is IPv6 and the PDN Type of the CSR message received in step S305 is IPv4, IPv6, or IPv4v6, IPv6, or IPv6. this is

As another example, when the GW-setting PDN Type set according to the standard in step S301 is IPv4v6 for the APN and the PDN Type of the CSR message received in step S305 is IPv4, IPv6, or IPv4v6, IPv4, IPv6, or IPv4v6 Lt; / RTI >

Finally, the PGW 2 sends the IP of the PDN Type allocated in the step S309 or S311 to the Create Session Response (CSR) message as a response message to the CSR (Create Session Request) message received in the step S305, (S313)

4 is a flowchart illustrating an example of a PDN Type-based IP allocation method set in the present invention.

First, the UE 1 as a user terminal requests a connection to the LTE network through an Attach Request message, and the PDN Type is accessed in IPv4v6 as an example (S401).

Then, the MME 3 requests subscriber information through the ULR (User Location Request) message to the HSS 4 (S402).

The HSS 4 transmits the PDN Type value for each APN to the MME 3 through the ULA (User Location Answer) message in response to the ULR message in step S402, and the PDN Type value for each APN for the corresponding subscriber, A, and IPv4 (S403).

The MME 3 requests the PGW 2 to allocate an IP to the APN A in PDN Type IPv4 through a CSR (Create Session Request) message (S404).

The PGW (2) compares the IPv6 Preference, which is the PDN Type set for the APN A, with the IPv4, which is the PDN Type of the CSR, and allocates the preferred PDN Type if the preferred PDN Type can be allocated. PDN Type of CSR is assigned. That is, the PGW (2) allocates the IP of IPv4 which is the PDN type of the CSR according to the table of FIG. 6, even though the GW-setting PDN Type is IPv6 Preference and the CSR PDN Type is IPv4 for APN A S405).

The PGW 2 transmits the IP address of the IPv4 allocated in step S405 to the MME 3 in the CSR (Create Session Answer) message. At this time, since the PDN Type allocated from the network is different from the request of the UE 1, The Cause of the CSR is transmitted to the New PDN due to network preference (S406).

Finally, the MME 3 transmits an Attach Accept message to the UE 1 (S407).

FIG. 5 is a flowchart illustrating an example of a PDN Type-based IP allocation method set according to a communication standard in the present invention.

First, the UE 1 as a user terminal requests connection to the LTE network through an Attach Request message. In this case, a PDN Type is connected in IPv4v6 as an example (S501).

Then, the MME 3 requests subscriber information through the ULR (User Location Request) message to the HSS 4 (S502).

The HSS 4 transmits the PDN Type value for each APN to the MME 3 through the ULA (User Location Answer) message in response to the ULR message in step S402, and the PDN Type value for each APN for the corresponding subscriber, A, and IPv4 (S503).

The MME 3 requests the PGW 2 to allocate an IP to the APN A in PDN Type IPv4 through a CSR (Create Session Request) message (S504).

The PGW 2 compares the PDN Type of the APN A, which is the PDN Type, with the IPv4 of the PDS Type of the CSR, and as a result, the PDN Type is different. Therefore, the PGW 2 rejects the IP allocation according to the table of FIG. 6 (S505) CSR (Create Session Answer) message to the MME 3, and the Cause of the CSR is transmitted to the Preferred PDN Type not supported according to the communication standard to reject the call (S506).

Finally, the MME 3 transmits an Attach Reject message to the UE 1 (S507).

Meanwhile, according to the method for allocating IP in the LTE system, a computer-readable recording medium on which a program for causing the computer to execute the method can be implemented.

Meanwhile, according to the method for IP allocation in the LTE system described above, an application stored in a medium can be implemented in order to combine the method with hardware and execute the method.
