Description

TECHNICAL FIELD OF PARTIAL UPGRADE OF HANDHELD TERMINAL SOFTWARE WITH PARTIAL PATCH AND HANDHELD TERMINAL PERFORMING THE SAME}

The present invention relates to a method for upgrading portable terminal software and a portable terminal for performing the same, and more particularly, to a method for partially upgrading the portable terminal software and a portable terminal for performing the same.

Recently, the hardware of the portable terminal is rapidly developing to high specifications, and the functions provided by the portable terminal based on such high specifications are also complicated and diverse. Accordingly, the types and functions of the software mounted on the portable terminal are also very complicated, and the production and supply of patches for error elimination and enhancement of the software is becoming a conventional follow-up process.

A patch is a series of machine instructions or programs issued to solve various errors and improve functions after software used in electronic devices such as computers and portable terminals is distributed. If this patching process is not done properly, the problem occurs in the portable terminal without the error being resolved, resulting in time, cost and security losses.

The user of the portable terminal needs to upgrade his portable terminal software using a patch to prevent such losses. In order to upgrade the portable terminal software, a user typically needs to visit a service center of the portable terminal or directly access the service site of the portable terminal through an internet communication network and directly download and install the corresponding patch.

A method of avoiding such a cumbersome process and improving the usability in upgrading the portable terminal software has been proposed. Korean Laid-Open Patent No. 2006-0065079 ("Method for providing a software upgrade of a communication terminal using a short message") generates an upgrade notification short message for software upgrade and transmits it to the communication terminal, and transmits an upgrade notification short message from the communication terminal. When the upgrade request signal is received, a version of software corresponding to the upgrade request signal is transmitted to the communication terminal.

In addition, Korean Patent Publication No. 2000-0018398 ("Software Upgrade Method of Mobile Communication Terminal Using Wireless Communication") stores software data received from a base station in a downloading data storage unit, and stores existing software stored in a flash ROM. After moving to the RAM, the downloading data stored in the downloading data storage unit is read out and upgraded to the flash ROM.

In addition, Korean Patent No. 10-0538627 ("How to upgrade the software part of the wireless communication terminal") compares the software currently installed in the wireless communication terminal with the new software to be upgraded to download different parts of the wireless communication terminal Upgrade the software, but at this time, modify the distributed loading (scatter loading) file of the software downloaded to the terminal to minimize the change of the software.

However, the method of Korean Patent Laid-Open Publication No. 2000-0018398 is a method of upgrading the entire software code stored in a flash ROM, which is inefficient as a method for removing an error caused by only a part of the software code, and a flash ROM is Because of the limited number of erases and writes, frequent upgrades to software code stored in flash ROMs result in shortened flash ROM lifetimes.

In addition, the Korean Patent No. 10-0538627 has a problem in that the software upgrade on the RAM area by the modification of the distributed loading file is erased when it is placed in the non-energized state.

Accordingly, an object of the present invention is to provide a partial upgrade method of portable terminal software using a partial patch and a portable terminal performing the same in order to minimize the burden of upgrading the portable terminal software.

1 is a flowchart illustrating a method of partially upgrading portable terminal software using a partial patch according to an embodiment of the present invention.

Referring to FIG. 1, a software partial patch is downloaded from a base station (BS) (step S110).

The software partial patch may comprise a software patch for at least one application program interface function. The application program interface (API) refers to an interface that allows an application program to use functions of other programs such as a computer operating system (OS) or a database management system (DBMS). The software of the portable terminal includes at least one function including the at least one API instruction, which is hereinafter referred to as an API function.

The software partial patch may include a patch for a specific API function included in specific software of the portable terminal. The specific API function to which the software partial patch is applied is stored in a storage space corresponding to a specific block address or a specific page address in the volatile storage unit 367. The software partial patch may include the specific block address or the specific page address in the volatile storage unit 367 to which the software partial patch is applied.

The volatile storage unit unit 367 may include at least one volatile memory. The volatile memory device may be one of an synchronous DRAM (SDRAM) and an synchronous RAM (SRAM). The software code stored in the nonvolatile storage unit 361 may be loaded and executed in the volatile storage unit 367 by an operating system of the portable terminal.

The nonvolatile storage unit 361 may include at least one non-volatile memory. The nonvolatile memory device may store software code and a software partial patch for driving and functioning the portable terminal.

Through scatter loading, the software binary code may be loaded to a specific address in the volatile storage unit in units of an object code or the like. By creating a separate object code for each API function and adjusting the linker options, one API function can be mapped to one or more integer blocks or pages.

The block means the minimum unit of the physical storage space divided into the same size, and the page means the minimum unit of the address space divided into the same size. One page may have a size of 512 bytes or 2048 bytes. For example, a storage device having an 8K address space and a 4K physical storage space may be divided into eight pages and four blocks divided by the size of 1K word. Given within four pages may correspond to one of the four blocks.

From the base station to at least one API function through any one of a short message service (SMS), a multimedia messaging system (MMS) and a broadband messaging service (BMS). You can download a partial patch for the software.

Next, it is determined whether the software of the portable terminal is the application target of the downloaded software partial patch (step S120). In this case, identification information of the downloaded software partial patch may be compared with identification information of the portable terminal.

The identification information of the downloaded software partial patch may include a portable terminal model ID to which the downloaded software partial patch is to be applied and version information of the downloaded software partial patch.

The identification information of the portable terminal may include a model ID of the portable terminal, software version information of the portable terminal, and version information of a software partial patch already stored in the portable terminal.

In determining whether the software of the portable terminal is the application target of the downloaded software partial patch, the portable terminal model ID to which the downloaded software partial patch is to be applied and the model ID of the portable terminal coincide with each other. It may be determined whether the version is higher than the software version of the portable terminal and the version of the software partial patch already stored in the portable terminal.

For example, when the downloaded version of the software partial patch is 1.2, the software version of the portable terminal is 1.0, and the version of the software partial patch already stored on the portable terminal is 1.1, Top downloaded software part patches are applied.

In addition, when the downloaded software partial patch version is 1.1, the software version of the portable terminal is 1.0, and the version of the software partial patch already stored in the portable terminal is 1.2, the upper level is downloaded to the software of the portable terminal. The software partial patch you received is not applied.

Next, when the software of the portable terminal is the application target of the downloaded software partial patch, the downloaded software partial patch is stored in the nonvolatile storage unit of the portable terminal (step S130). In this case, the downloaded software partial patch may be stored in a form recognized by an embedded file system (hereinafter referred to as EFS) or a memory chunk.

The EFS may be at least one of a RAM Disk, a RAMFS, a Compressed RAM File System (CRAMFS), a Journaling Flash File Systems (JFFS2), a Network File System (NFS), and a PROC File System.

The memory chunk refers to a chunk of raw binary code including only a minimum of headers, which does not require separate parsing to grasp contents.

After the storage of the software partial patch is completed, the user is asked to determine whether to apply the stored software partial patch in at least one of beep sound, ring tone, vibration, and text and when to apply the stored software partial patch. A notification can be made (step S140). The application point is as described later.

After the storage of the software partial patch is completed (step S130) or the user is informed to determine whether to apply the stored software partial patch and when to apply (step S140), whether or not to apply the stored software partial patch from the user Can be determined (step S150).

When the application of the stored software partial patch is permitted from the user, an application time point of the stored software partial patch may be determined from the user (step S160). The application time point may be any one of the next restart of the portable terminal, the next loading of the software to which the stored software partial patch is applied, and immediately after the downloaded software partial patch is stored.

Next, the stored software partial patch is applied to the software binary code in the volatile storage unit of the portable terminal (step S170).

Specifically, the software binary code applied to the software partial patch stored in the nonvolatile storage unit may be loaded by a boot loader or an operating system when the portable terminal is reset. Can be. In this case, the software binary code to be applied may be replaced with the contents of the software partial patch and loaded into the volatile storage unit.

Alternatively, at the next loading of the software to which the stored software partial patch is applied, the software binary code to be applied may be replaced with the contents of the software partial patch and loaded into the volatile storage unit.

Alternatively, as soon as the downloaded software partial patch is stored, the software binary code to be applied may be replaced with the contents of the software partial patch and loaded into the volatile storage unit.

When the stored software partial patch is applied at the next loading of the software to which the stored software partial patch is applied or immediately after the downloaded software partial patch is stored, the applied software is already loaded into the volatile storage unit. If it is running, any one of unloading the software to be applied and restarting the portable terminal may be performed.

The operating system of the portable terminal may stop the operation of the software to be applied and unload it from the volatile storage unit when the software to be applied is already loaded and executed in the volatile storage unit.

Alternatively, the operating system of the portable terminal may restart the portable terminal when the operation of the software that is the application target or the unloading from the volatile storage unit is not possible.

If the size of the stored software partial patch is larger than the size of the software binary code to be applied, the software binary code to be upgraded is upgraded to a portion equal to the size of the software binary code to be applied among the stored software partial patches. A portion of the stored software portion patch except for the size of the software binary code that is the application target may be stored in an empty storage space in the volatile storage unit.

If the size of the stored software partial patch is smaller than the size of the software binary code to which the application target is applied, upgrade the software binary code to which the application target is applied with the stored software partial patch, and the stored software in the storage space of the software binary code to which the application target is applied. You can fill parts with null values except for the size of the partial patch.

2 is a conceptual diagram illustrating a method of upgrading a software binary code to which a software partial patch is applied by using a software partial patch of various sizes. For the sake of simplicity, the size of the software binary code to which the software partial patch is applied corresponds to the size of the unit block or the unit page of the volatile storage unit 367.

Referring to FIG. 2, the size of a software partial patch applied to block 3 or page 10 in the volatile storage unit 367 is equal to the size of the storage space of the software binary code. For example, if the size of the software partial patch and the storage space of the software binary code to be applied are equal to 2,048 bytes, the software partial patch is assigned to block 3 or 10 in the volatile storage unit unit 367. You can apply it directly to the page.

In another case, the size of the software partial patch applied to block 20 or page 5 in the volatile storage unit 367 is larger than the storage space of the software binary code to be applied. For example, if the size of the software portion patch is 3,072 bytes and the storage space of the software binary code to be applied is 2,048 bytes, the 2,048 byte portion of the software portion patch may be applied first. The remaining 1,024 byte portion of the software portion patch may be stored in any empty storage space in the volatile storage unit portion 367. In this case, the divided and stored two parts can be executed as one binary code by scatter loading and function entry / exit code.

In another case, the size of the software partial patch applied to block 34 or page 3 in the volatile storage unit 367 is smaller than the storage space of the software binary code to be applied. For example, if the size of the software partial patch is 1,536 bytes and the storage space of the software to be applied is 2,048 bytes, the entire software partial patch may be applied to the storage space of the software to be applied. The remaining 512 bytes of the storage space of the software to be applied may be filled with a null value.
