The application layer module 30 includes an API layer module 33 including a handset application layer module 31, a run-time engine 32 that is a driving engine of the application 40, and API functions for executing an application. It is configured to include).

The handset application layer module 31 (HAL) is an abstraction layer for maintaining hardware independence of the platform, and supports upper layers to operate independently of the native system on the handset application layer module 31. For example, in the case of a domestic CDMA terminal, porting only the handset application layer module 31 on the Qualcomm OS (REX) becomes a platform for the terminal, and porting only the handset application layer module 31 to the window environment emulates a window. Becomes

The API layer module 33 is a set of functions that the application 40 can call to the operating system for any processing. The API layer module 33 controls the handset hardware 10 through the handset application layer module 31 and each application. APIs substantially used at 40 are included.

In the present invention, the API layer module 33 of the mobile platform is defined, the API layer module 33 is a group API link table consisting of the API function classified by group, the address of each API function belonging to the group, It further comprises an API group link table consisting of addresses of the group-specific API link tables. This will be described in more detail with reference to FIGS. 2 and 3.

2 is an API group table for explaining the present invention, and shows an embodiment of an API function classified according to groups.

As shown, in the present invention, each API function included in the API layer module 33 is divided into a plurality of groups 110 to 150, and each group 110 to 150 includes a plurality of API functions. .

That is, the API group includes the Network API group 110, the Graphic API group 120, the Kernel API group 130, the File API group 140, and the Utility API. Group 150, etc., network API group 110 consists of network API 1 (NetAPI 1), network API 2 (NetAPI 2), network API 3 (NetAPI 3), and graphical API group 120 With the graphics API 1 to the graphics API 4 (GrpAPI 1 to GrpAPI 4), the kernel API group 130 is composed of the kernel API 1 to the kernel API 3 (KnlAPI 1 to KnlAPI 3).

A method of calling API functions classified by groups as described above will now be described with reference to FIG. 3.

FIG. 3 is a conceptual diagram illustrating an API calling method in an API control method according to an embodiment of the present invention, and illustrates an concept of an application calling an API group and an API function for each group described with reference to FIG. 2.

As shown, the API layer module 33 includes an API group link table 200 and a group API link table 300 to call API functions by groups.

The API group link table 200 is composed of addresses of group API link tables, and the group API link table 300 is composed of pointers to each API function belonging to a specific group, that is, an address where each API function is actually located. .

The network API group of the API group link table 200 is a list linked to point to the network API 1 (NetAPI 1) through the API link table 300 and continuously to the network API 3 (NetAPI 3). It is composed.

Therefore, the application calls the corresponding API function using the API link table 300 and the API group link table 200 for each group. That is, the application links to the corresponding group including the API function to be called using the group-specific API link table address of the API group link table 200, and again returns the API function pointer of the group-specific API link table 300. Call the corresponding API function.

Due to the above call structure, when a specific group of APIs is modified or added to the mobile platform, the API can be upgraded by changing only the corresponding API group link table and the API link table for each group. Referring to Figure 7 as follows. 4 and 5 show how to modify the API, and FIGS. 6 and 7 show how to add the API.

First, FIG. 4 is a conceptual diagram illustrating an API group modification method in an API control method according to an embodiment of the present invention.

4 illustrates a case in which all API functions belonging to a specific API group, that is, the entire group are modified. First, when the modified API functions NetnewAPI 1 and NetnewAPI2 are downloaded, the downloaded API functions NetNet API in the terminal's file system. 1, NetnewAPI2) is installed and loaded into memory.

In addition, in order to enable an application to call the newly installed API function as described above, the API link table of the corresponding API group (Network) of the API link table 310 for each group includes an address of an API function before being modified. The new API link table (nNetwork, 312) consisting of the old API link table (oNetwork) 311 and the address of the modified API function is classified and corrected. At this time, it is preferable to maintain the old API link table 311 in preparation for future recovery.

In addition, when the API link table is added and modified, the API group link table 210 should be modified to include the address of the new API link table 312, so that the application can use the API function before the modification. It is preferable to include the address of the old API link table 311 together.

As described above, the API is updated in groups. When a new API group is downloaded, the API group downloaded to the file system of the terminal is installed, loaded into the allocated memory, and the contents of the API link table are modified.

At this time, in order to modify the API function, the API must be called indirectly through the API group link table 210 and the API link table 310. The API change is always compared with the version in the new API group file by comparing the platform version. It is advisable to check for a match so that modifications are made only when they match.

When the modified API function is loaded and the table is modified as described above, the application links to the Network API group using the API group link table 210 when the API function is called in the Network API group, and the API function in the Network API group. Refer to the scene API link table 312 to call the modified API function can be called.

Meanwhile, a case in which only a specific API in a group is modified will be described with reference to FIG. 5 as follows.

5 is a conceptual diagram illustrating an API modification method of an API control method according to an embodiment of the present invention.

First, when an API function (NetnewAPI 2) to be added in a specific API group (Network API group) is downloaded, the downloaded API function is installed in the file system of the terminal and loaded in the memory.

When the new API function (NetnewAPI 2) is loaded as described above, the API link table of the Network API group, which is the corresponding API group, to which the API function (NetnewAPI 2) to be added is included in the API link table 320 for each group. The table 321 and the scene API link table 322 are classified and modified. At this time, the old API link table 321 is preferably preserved in order to be able to use the API function before the application is modified.

The old API link table 321 is composed of addresses of API functions before the API function is added, and there is no modification. The new API link table 322 is an address of an unmodified API (NetoldAPI 1) function in the Network API group. And the address of the API function (NetnewAPI 2) to be added.

Therefore, when an application calls an API function included in a network API group, the API function (NetnewAPI 2) modified by referring to the new API link table 322 for the corresponding group called by the API group link table 220 is called. Can be called.

Next, FIG. 6 is a conceptual diagram illustrating a method of adding an API group in an API control method according to an embodiment of the present invention, and illustrates a concept of adding a new API group.

As shown, when an API group to be added (New API group) is first downloaded, the downloaded API group is installed in the file system of the terminal and loaded into the memory.

As described above, when loading of a new API group (New API group) consisting of new API functions (NewAPI 1 to 3) is completed, a new API link composed of addresses of the respective API functions (NewAPI 1 to 3). The tables nNew and 331 are newly created.

In order to link to the newly created API link table 331, the API group link table 230 is classified into the old API group link table Old Tbl 231 and the new API group link table New Tbl 232.

The old API group link table (Old Tbl) 231 is composed of addresses of group-specific API link tables before a new API group is added, and the new API group link table (New Tbl, 232) is used before a new group is added. It includes the address of the new API link table 331 of the newly added API group to the address of the group-specific API link tables.

In this case, since the contents of the old API group link table 231 include all of the contents of the new API group link table 232, the old API group link table 231 is preferably deleted.

Therefore, when the application calls an API function, the application links to the added API group by referring to the scene API group link table 232 and belongs to the scene API group by referring to the scene API link table 331 of the newly added API group. Call and use API functions.

Lastly, FIG. 7 is a conceptual diagram illustrating an API addition method among API control methods according to an embodiment of the present invention, and illustrates a concept of adding a new API function to a specific API group.

As shown, when a new API function (NetnewAPI 3) is added within a specific API group (Network API), the API link table 340 consisting of the addresses of each API function is replaced by the old API link consisting of the addresses of previous API functions. It is classified and modified into a new API link table (nNetwork, 342) including the table (oNetwork, 341), the address of the previous API function, and the address of the newly added API function (NetnewAPI 3).

In this case, since the new API link table 342 includes all the contents of the old API link table 341, the old API link table 341 may be deleted.

If the API link table 340 is classified into the old API link table 341 and the new API link table 342 as described above, the API group link table 240 is the old API link table 341 and the new API link table. It is modified to include all addresses of 342.

In this case, when the old API link table 341 is deleted, the API group link table 240 will be modified to include only the address of the new API link table 342.

Therefore, the application refers to the API group link table 240 to link to the corresponding API group, and the corresponding API group is linked to the new API link table 342 so that the application can use the newly added API function. .
