Abstract

Disclosed herein is an access point name (APN) access method including: (a) checking whether an APN server is accessible via a wireless network connected to a telematics device that is powered on when an amount of time during which an APN change alarm message can be received has elapsed; (b) checking whether an APN update is necessary using an administration APN pre-stored in the telematics device when the APN server is not accessed, and acquiring APN update data from the APN server when the APN server is accessed; and (c) transmitting and receiving data between the telematics device and a data server using the acquired APN update data.

Claims

1. An access point name (APN) access method comprising:

(a) checking a service state of a wireless network connected to a telematics device when the telematics device is powered on after a specific time has elapsed during a power-off state;

(b) checking whether an APN server is accessible using a pre-stored old APN when the service state of the wireless network is normal;

(c) checking whether an APN update is necessary using an administration APN pre-stored in the telematics device when the APN server is not accessible using the old APN;

(d) receiving APN update data from the APN server using the administration APN when the APN update is necessary;

(e) updating the old APN with a new APN based on the received APN update data; and

(f) transmitting and receiving data between the telematics device and a data server using the new APN, wherein step (c) comprises;

transmitting a message including the administration APN to the APN server; and

when the APN server is accessible using the old APN, acquiring the APN update data from the APN server in response to the telematics device receiving a response message from the APN server indicating that access to the APN server is accepted, the APN update data including a new APN which is different from the old APN.

2. The APN access method according to claim 1, wherein step (b) further comprises:

(b-1) determining whether an access reject message is received from the APN server, which has checked the old APN; and

(b-2) determining that the APN server cannot be accessed when the access reject message is received.

3. The APN access method according to claim 2, wherein step (d) further comprises:

(d-1) transmitting the administration APN to the APN server when the access reject message is received; and

(d-2) receiving the APN update data from the APN server upon determining that the administration APN is equivalent to the pre-stored administration APN.

4. A non-transitory computer-readable medium having a program for performing the APN access method according to claim 1 recorded thereon.

5. A telematics device comprising:

a wireless network access unit checking a service state of a wireless network connected to the telematics device when the telematics device is powered on after a specific time has elapsed during a power-off state;

a server access checking unit checking whether an access point name (APN) server is accessible using a pre-stored old APN when the service state of the wireless network is normal;

an APN update unit checking whether an APN update is necessary using an administration APN pre-stored in the telematics device when the APN server is not accessible using the old APN, receiving APN update data from the APN server using the administration APN when the APN update is necessary, and updating the old APN with a new APN based on the received APN update data; and

a data transmission unit transmitting and receiving data to and from a data server using the new APN,

wherein the APN update unit transmits a message including the administration APN to the APN server, and when the APN server is accessible using the old APN, acquires the APN update data from the APN server in response to the telematics device receiving a response message from the APN server indicating that access to the APN server is accepted, the APN update data including a new APN which is different from the old APN.

6. The telematics device according to claim 5, wherein the server access checking unit includes an old APN access unit which:

determines whether an access reject message is received from the APN server, which has checked the old APN; and

determines that the APN server cannot be accessed when the access reject message is received.

7. The telematics device according to claim 6, wherein the APN update unit:

transmits the administration APN to the APN server when the access reject message is received; and

receives the APN update data from the APN server upon determining that the administration APN is equivalent to the pre-stored administration APN.

8. A telematics device comprising:

a memory configured to store at least one program; and

a processor configured to execute the at least one program,

the at least one program including instructions for;

checking a service state of a wireless network connected to the telematics device when the telematics device is powered on after a specific time has elapsed during a power-off state;

checking whether an APN server is accessible using a pre-stored old APN when the service state of the wireless network is normal;

checking whether an APN update is necessary using a pre-stored administration APN when the APN server is not accessible using the old APN;

receiving APN update data from the APN server using the administration APN when the APN update is necessary;

updating the old APN with a new APN based on the received APN update data; and

transmitting and receiving data to and from a data server using the new APN, wherein the checking of whether the APN update is necessary comprises;

transmitting a message including the administration APN to the APN server; and

when the APN server is accessible using the old APN, acquiring the APN update data from the APN server in response to the telematics device receiving a response message from the APN server indicating that access to the APN server is accepted, the APN update data including a new APN which is different from the old APN.

9. The telematics device according to claim 8, wherein the at least one program includes further instructions for:

determining whether an access reject message is received from the APN server, which has checked the old APN; and

determining that the APN server cannot be accessed when the access reject message is received.

10. The telematics device according to claim 9, wherein the at least one program includes further instructions for:

transmitting the administration APN to the APN server when the access reject message is received; and

receiving the APN update data from the APN server upon determining that the administration APN is equivalent to the pre-stored administration APN.
