Will be received.

In the location inquiry step (B), the OTA server 130 inquires the location to the location information server 142 using the SMSReqeust (location inquiry message) to send a message (OTA message). The aforementioned SMSRequest may be a CDMA MAP standard message, and the location information server 142 may be a home location register (HLR).

In the OTA channel setting step (C), in order to set up the OTA channel, the OTA server 130 uses the terminal location information inquired in the location inquiry step (B) to the exchange 141 for a SMDPP (Short Message Delivery Point to Point) Send a message. The SMDPP message includes a mobile identity number (MIN), an electronic serial number (ESN), a service indicator, a teleservice indicator, and an SMS_Bearer_Data, of which SMS_Bearer_Data includes an Over The Air Parameter, which includes a START command for starting an OTA channel. Administration) Request (OTA channel setup request message) is included. Here, the Over The Air Parameter Administration (OTAPA) Request may be a CDMA OTA standard message, and is a message defined in the IS-683 standard and the IS-725 standard. In addition, the channel of the terminal 150 moves to a traffic channel, receives an OTAPA request from the exchange 141, and sets up an OTA channel. Accordingly, smdpp from the exchange 141 to the OTA server 130. Message (OTA channel setup response message) is sent. The exchange 141 mentioned above may be a mobile switching center (MSC).

In the protocol performance inquiry step (D), the OTA server 130 sends an SMDPP message containing SMS_Bearer_Data including a Protocol Capability equest to the exchange 141 to send a Protocol Capability Response (Protocol Performance Response message). You will receive a smdpp message that includes SMS_Bearer_Data.

In the new map information providing step (E) in which the updated map information is actually transmitted to the terminal 150, the OTA server 130 includes the SMS_Bearer_Data including the OTA Download Reqeust to the exchange 141. By transmitting the SMDPP message, the update map information is transmitted through the OTA channel set in the terminal 150.

In the new map information providing confirmation step (F), the OTA server 130 transmits the SMDPP including the SMS_Bearer_Data including the Commit Request to the exchange 141 and responds thereto (map information updating). Acknowledgment message).

In the OTA channel release step (G), the OTA server 130 includes SMS_Bearer_Data including an OTAPA Request (OTA channel release request message) including a STOP command for releasing the OTA channel preset to the corresponding exchange 141. The OTA channel is released by transmitting the SMDPP message to the corresponding exchange 141 to release the preset traffic channel.

In the map information update response step (H), the OTA server 130 transmits a Service_Response (OTA service response message) including the MDN and the result code to the navigation server 120.
