Abstract

A web browser of an information processing terminal serving as a user agent (UA) is capable of registering function information of a local service that a local server (printer) provides, which is acquired by search, and function information of a service acquired via a site that a server provides. When receiving Invocation in Web Intents, the web browser displays a list of the registered function information to prompt the user to select a service to be used. If function information that has previously been registered has been found by search, the web browser updates display of the list of the registered function information according to a result of the search.

Claims

1. An information processing terminal having a relay function for causing a client that manages data and a service that provides a function using the data managed by the client to cooperate with each other, the information processing terminal comprising:

a first acquisition unit configured to acquire first function information, which is used to request a first service that a network device connected to a network provides, by searching for services via the network using a predetermined network protocol;

a second acquisition unit configured to acquire second function information, which is used to request a second service, via a site of a network device that provides the second service;

a registration unit configured to execute registration processing of the first function information acquired by the first acquisition unit and the second function information acquired by the second acquisition unit using the relay function; and

a control unit configured to control display of a list of function information including the first function information and the second function information registered according to the registration processing,

wherein, if function information that has previously been registered according to the registration processing has been found by a search for services via the network using the predetermined network protocol, the control unit updates display of the list according to a result of the search.

2. The information processing terminal according to claim 1, wherein the result of the search includes a state of a service corresponding to the function information that has previously been registered.

3. The information processing terminal according to claim 2, wherein, if a registration of the function information that has previously been registered has been deleted according the state of the service included in the result of the search.

4. The information processing terminal according to claim 2, wherein a search for acquiring the state is not performed with respect to the second service corresponding to the second function information acquired by the second acquisition unit.

5. The information processing terminal according to claim 2, further comprising a management unit configured to manage function information that has been registered according to the registration processing while distinguishing between the first function information acquired by the first acquisition unit and the second function information acquired by the second acquisition unit.

6. The information processing terminal according to claim 5, wherein the management unit further manages, as extension information of the first function information, a state of a service acquired by using the predetermined network protocol.

7. The information processing terminal according to claim 2, further comprising a setting unit configured to set whether to perform the search based on a state of registration of the first function information by the registration unit,

wherein the first acquisition unit controls execution of the search based on the state of registration of the first function information by the registration unit and a result of setting by the setting unit.

8. The information processing terminal according to claim 7, wherein the first acquisition unit, when not performing the search, performs update processing for acquiring, from a network device that provides the function information that has previously been registered, a state of a service corresponding to the function information that has previously been registered.

9. The information processing terminal according to claim 8, wherein the setting unit is configured to set whether to perform the update processing, and

wherein the first acquisition unit, when not performing the search, controls execution of the update processing based on the result of setting by the setting unit.

10. The information processing terminal according to claim 1, wherein the first acquisition unit searches for a network device connected via the network, and acquires the first function information, which is used to request the first service that the network device provides, and

wherein, if an instruction for registering function information for requesting a service that a network device selected by a user provides has been issued via a screen indicating a result of search for the network device by the first acquisition unit, the registration unit registers the first function information, which is used to request the first service that the network device provides, associated with the issued instruction.

11. A control method for an information processing terminal having a relay function for causing a client that manages data and a service that provides a function using the data managed by the client to cooperate with each other, the control method comprising:

acquiring first function information, which is used to request a first service that a network device connected to a network provides, by searching for services via the network using a predetermined network protocol;

acquiring second function information, which is used to request a second service, via a site of a network device that provides the second service;

executing registration processing of the acquired first function information and the acquired second function information using the relay function;

controlling display of a list of function information including the first function information and the second function information registered according to the registration processing; and

updating, if function information that has previously been registered according to the registration processing has been found by a search for services via the network using the predetermined network protocol, display of the list according to a result of the search.

12. A computer-readable storage medium storing a computer program for realizing a relay function, which causes a computer to execute a control method for causing a client that manages data and a service that provides a function using the data managed by the client to cooperate with each other, the control method comprising:

acquiring first function information, which is used to request a first service that a network device connected to a network provides, by searching for services via the network using a predetermined network protocol;

acquiring second function information, which is used to request a second service, via a site of a network device that provides the second service;

executing registration processing of the acquired first function information and the acquired second function information;

controlling display of a list of function information including the first function information and the second function information registered according to the registration processing; and

updating, if function information that has previously been registered according to the registration processing has been found by a search for services via the network using the predetermined network protocol, display of the list according to a result of the search.
