Abstract

Bearer attribute information (20) indicating at least one bearer usable by an application and the priority of the bearer is compared with the characteristic information (21) of a communication terminal, thereby generating a bearer list (23) including, of bearers of the bearer attribute information, bearers usable by the communication terminal and the priorities of the bearers. The bearer list is stored in a database (DB). A bearer to be used by the application is selected in accordance with the priority in the bearer list, and the communication process of the application is executed. This allows to implement an application execution environment that sufficiently reflects the application provider'"'"'s intention. The bearer list can be changed by the user via a user interface (24). In this case, the user can change the bearer list only within the range stored in the database. This prevents any arbitrary setting by the user.

Claims

1. A bearer selection method characterized by comprising the steps of:

generating, on the basis of bearer attribute information indicating at least one bearer usable by an application to be executed in a communication terminal and a priority of the bearer, and characteristic information of the communication terminal, which is stored in the communication terminal in advance, a bearer list including, of bearers of the bearer attribute information, bearers usable by the communication terminal and priorities added to the bearers;

storing the generated bearer list in a memory of the communication terminal; and

selecting a bearer to be used by the application in accordance with the priority in the bearer list stored in the memory.

2. A bearer selection method according to claim 1, characterized by further comprising the step of displaying the bearer list stored in the memory.

3. A bearer selection method according to claim 2, characterized by further comprising the steps of:

changing the displayed bearer list on the basis of an input from an input device of the communication terminal; and

storing the changed bearer list in the memory.

4. A bearer selection method according to claim 1, characterized in that

the characteristic information of the communication terminal is information representing resources usable by the communication terminal, and

in the generating step, the bearer list is generated by selecting, of the bearers of the bearer attribute information, bearers included in the resources of the characteristic information as the bearers usable by the communication terminal.

5. A bearer selection method according to claim 4, characterized by further comprising the step of downloading the bearer attribute information from an application server,

wherein in the generating step, the bearer list is generated on the basis of the downloaded bearer attribute information.

6. A bearer selection method according to claim 2, characterized in that in the displaying step, the bearer list stored in the memory is displayed in accordance with a user interface.

7. A bearer selection method according to claim 6, characterized by further comprising the step of changing the bearer list stored in the memory interactively in accordance with the user interface.

8. A bearer selection method according to claim 1, characterized by further comprising the step of changing the priority in the bearer list stored in the memory.

9. A bearer selection method according to claim 1, characterized in that in the selecting step, the bearer is selected in descending order of priority in the bearer list stored in the memory.

10. A bearer selection method according to claim 1, characterized by further comprising the step of using a bearer preset in the communication terminal when the bearer list stored in the memory includes no bearer usable by the application.

11. A bearer selection apparatus characterized by comprising:

a first storage unit which stores bearer attribute information indicating at least one bearer usable by an application to be executed in a communication terminal and a priority of the bearer, and characteristic information of the communication terminal, which is stored in the communication terminal in advance;

an attribute verification unit which generates a bearer list including, of bearers of the bearer attribute information, bearers usable by the communication terminal and priorities added to the bearers by comparing the bearer attribute information with the characteristic information, which are stored in said first storage unit;

a second storage unit which stores the generated bearer list; and

a communication control unit which executes a communication process of the application by selecting a bearer to be used by the application in accordance with the priority in the bearer list stored in said second storage unit.
