The OTASP processing method of the mobile communication terminal to receive the OTA data from the data received before the call disconnection when performing the OTASP processing again.

The above-mentioned OTASP service is to alleviate the inconvenience of the subscriber visiting the dealership and registering the subscription. The OTASP service can be directly used by the subscriber by directly using the mobile terminal purchased through a convenience store or other distribution store. Say a service to help.

That is, the above-described OTASP service simplifies the complicated procedure of registration between subscriber and operator through reliable data communication between voice call establishment, and provides a function to support secure and reliable registration procedure in real time. The characteristics of OTASP are as follows.

Set up CSC (Customer Service Center) and Voice calls of network operators.

Over the Air (OTA) programming of multiple NAMs (Number Assignment Modules).

Authentication key generation and shared secret data (SSD) renewal.

Unlike other supplementary service functions, the above-described OTASP is a system for enabling a service before a terminal and a subscriber are registered in a network, as shown in FIG. 1. The terminal (MS) 1, the base station 2, It is composed of MSC (3), OTAF (OTA function) (4), HLR (5), AuC (6), CSC (7) to provide OTASP services.

2 is a signal flow diagram illustrating a process for the above-described OTASP service.

As shown in FIG. 2, the mobile communication terminal connects the OTA call to the OTAF 4 via the MSC 3 in order to receive the mobile communication service (S1), where the mobile communication terminal performs the OTA call connection. Refers to a mobile communication terminal that supports a plurality of NAM (Number Assignment Module) and is reprogrammed after initial programming. In addition, it must support IMSI (Temporary Mobile Station Identity) and TMSI (Temporary Mobile Station Identity), and can generate A-key (Authentication Key) and update Shared Secret Data (SSD).

After the OTA call connection is established between the mobile communication terminal 1 and the OTAF 4 having the above-described functions, the mobile communication terminal is registered as a service subscriber of the service provider by performing an OTA session processing process for the OTASP service. The mobile communication service can be provided.

The above-described OTA session processing includes a series of processes for registering an electrical serial number (ESN), programming a NAM, generating an authentication key, assigning a mobile identfication number (MIN) to a mobile terminal, and generating a subscriber profile. Say.

By the OTA session processing as described above, the mobile communication terminal of the present invention is subscribed to the mobile communication service provider, thereby providing a mobile communication service.

However, the OTASP service process in the prior art as described above, the OTASP and the OTAF in the state that the processing by the OTA session is not completed while performing the OTA session processing to the OTA (over the air) (4) When the call is disconnected, the downloaded data before the disconnection is not stored in the terminal and all data are deleted. Therefore, the process of OTASP service needs to be performed again from the beginning.

Accordingly, the present invention is to solve the above-mentioned problems in the prior art, the data downloaded by the OTA session processing when the OTA call connection is disconnected during the OTASP processing of the mobile communication terminal for providing the mobile communication service and OTASP of a mobile communication terminal that facilitates the subscriber registration process of the mobile communication terminal by performing the OTASP service processing process after the downloaded procedure before the call is stopped by notifying the breakpoint of the OTA session processing process. Its purpose is to provide a treatment method.

OTP processing method for registration in the service provider of the mobile communication terminal of the present invention for achieving the above object, OTA processing between the mobile communication terminal and OTF, the mobile communication terminal and OTAF (OTAF) A first process of performing an OTI call connection between the first process, a second process of transmitting and receiving a message according to an OTA session processing process in the call connection state, and an OTI session processing process of the second process A third process of storing, by the mobile communication terminal, a received message from the OTAF; and reconnecting an OTI call between the mobile communication terminal and the OTAF when the call is disconnected during the processing of the third process. A fourth process of notifying the OTAF of the OTI wire processing stored in the third process by the mobile communication terminal, and after the fourth process Characterized in that obtained by processing from a fixed period after the first message stored in the last in the third process, a fifth process for performing OTA session processing.

The fourth process includes steps 4-1 of reconnecting an OTT call, and session configuration information for requesting OTI session processing information previously terminated by the OTT after the OTT call reconnection. And step 4-2 of transmitting the request message and step 4-3 of transmitting the session configuration information response message to the OTAF according to the request of step 4-2.

The session configuration information request message is composed of an OTASP message type field.

The session configuration information response message is composed of an OTASP message type, an OAT session result code, a session processing completion, a download message number, and a message ID field received after a call drop.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

3 is a flowchart illustrating an OTP processing method of a mobile communication terminal according to an embodiment of the present invention. As shown in FIGS. 1 and 3, the mobile communication terminal 1 and OTAF (over) are used for OTASP processing. The OTA call is connected between the air function (4) (S11).

After the OTA call is connected in step S11, the OTA session processing is performed by exchanging messages between the mobile communication terminal 1 and the OTAF 4. Herein, the OTA session processing process is performed by registering an electrical serial number (ESN), programming a NAM, generating an authentication key, assigning a mobile identfication number (MIN) to a mobile terminal, and a subscriber profile, as described in the above-described prior art. It is a series of processes to create. The mobile communication terminal 1 temporarily stores the message when the transmission of the message (parameter) received from the OTAF 4 is completed in the above-described OTA session processing, and then stores the entire message in the nonvolatile memory when the transmission of the specific message is completed. (S12).

The OTAF 4 determines whether the OTA call is disconnected while the above-described OTA session processing is performed in step S12 (S13).

If the OTA is disconnected as a result of the determination of S13, the call of the OTA is reconnected between the mobile communication terminal and the OTAF again (S14).

After the OTA call is reconnected by the S14 process, the OTAF 4 transmits a Session Configuration Request message to the mobile communication terminal, requesting processing information of the message transmission immediately before the OTA call is disconnected (S15). ). 4 shows the structure of the session configuration request message described above, and the session configuration request message is composed of an OTASP message type field.

Next, the mobile communication terminal 1 receiving the session configuration request message by the above-described step S15 transmits the session configuration response message to the OTAF 4 (S16). 5 shows the structure of the session configuration response message. As shown in FIG. 5, an OTASP message type (OTASP_MSG_TYPE), a result code (RESULT_CODE), a session processing completion (SESSION_COMPLETE), a RESERVED, and a download message number are shown. (NUM_MSG_ID), and a message ID (MSG_ID) field having message information received after a call drop.

The OTASP message type (OTASP_MSG_TYPE) field of the above-mentioned messages is set to '00010000' as to identify processing for the OTASP service.

The RESULT_CODE field is a field indicating the result of message transmission and reception during OTA call processing.

The SESSION_COMPLETE field is set to '1' if the previous OTA session terminated normally, or set to '0' if it did not terminate normally to identify whether the OTA session terminated normally. do.

The RESERVED field is filled with '0000000' as 7 bits to fill it with 8 bits because the session processing completed field is 1 bit.

The download message index (NUM_MSG_ID) field allows the mobile communication terminal to identify the number of messages received from the OTAF 4.

The message ID (MSG_ID) field enables identification of the last downloaded message during the OTA session processing before the OTA call is disconnected from the OTAF (4).

3, the OTAF 4 which has received the session information by the above-described step S16 re-performs the OTA session process from the process just before the OTA call is terminated (S17).

Thereafter, after OTA session processing by S17 is terminated and OTA call disconnection does not occur in step S13, the OTA session processing is not terminated by determining whether the entire processing of the OTASP service is terminated. If the OTA session processing is terminated, the S17 process is performed, and if the OTA session processing is terminated, the process for the OTASP service is terminated (S18).

The present invention described above does not perform an OTASP process from the beginning by storing parameter values previously transmitted when an OTA call is disconnected during an OTASP service procedure, but after a procedure that is received before the OTASP call is disconnected. By doing so, the OTASP process can be performed more quickly.
