Description

上記目的を達成するための一手段として、本発明の通信装置は以下の構成を有する。すなわち、通信装置であって、提供装置により第１のプロトコルを介して提供される第１のサービスを利用して所定の処理を実行する実行手段と、前記実行手段により前記所定の処理を実行中に、前記提供装置による前記第１のサービスの提供が停止した場合、前記第１のプロトコルとは異なる第２のプロトコルを介して、前記第１のサービスに対応する第２のサービスを前記提供装置が提供しているかを判定する判定手段と、前記判定手段により、前記第２のサービスを前記提供装置が提供していると判定された場合には、前記所定の処理を継続し、前記第２のサービスを前記提供装置が提供していないと判定された場合には、前記所定の処理を停止する制御手段と、を有することを特徴とする。 As a means for achieving the above object, the communication apparatus of the present invention has the following configuration. In other words, the communication device is an execution unit that executes a predetermined process using the first service provided by the providing device via the first protocol, and the execution unit is executing the predetermined process. In addition, when the provision of the first service by the providing device is stopped, the providing device provides a second service corresponding to the first service via a second protocol different from the first protocol. When the determination unit determines whether the providing device provides the second service, the predetermined process is continued, and the second process is continued. Control means for stopping the predetermined processing when it is determined that the providing device does not provide the service.

Claims

A communication device,
Execution means for executing predetermined processing using a first service provided by a providing device via a first protocol;
When provision of the first service by the providing device is stopped while the predetermined process is being executed by the execution means, the first service is transmitted via a second protocol different from the first protocol. Determining means for determining whether the providing device provides a second service corresponding to
If it is determined by the determination means that the providing device is providing the second service, the predetermined processing is continued, and the providing device does not provide the second service. If it is determined, a control means for stopping the predetermined process;
A communication apparatus comprising:

Further comprising an acquisition means for acquiring information indicating a service providing status provided by the providing apparatus by a plurality of protocols;
The communication apparatus according to claim 1, wherein the determination unit determines whether the providing apparatus provides the second service based on the information acquired by the acquisition unit.

The communication apparatus according to claim 2, further comprising a management unit that manages the information acquired by the acquisition unit in association with the protocol information from which the information is acquired.

When the obtaining unit obtains information indicating that the providing device provides the second service via the second protocol, the management unit provides that the second service is provided. The communication apparatus according to claim 3, wherein the communication apparatus is managed in association with the second protocol.

When the acquisition unit acquires information indicating that the providing apparatus stops providing the second service via the second protocol, the management unit is provided with the second service. The communication apparatus according to claim 4, wherein information indicating that the information is discarded.

6. One of the first protocol and the second protocol is UPnP (Universal Plug and Play), and the other is mDNS (Multicast Domain Name System). The communication device according to any one of the above.

The communication apparatus according to claim 1, wherein the predetermined process is a print process.

2. The information processing apparatus according to claim 1, further comprising notification means for notifying a user of failure of the predetermined processing when the determination means determines that the providing device does not provide the second service. 8. The communication device according to any one of items 7.

A communication device control method comprising:
An execution step of executing a predetermined process using a first service provided by a providing device via a first protocol;
If the provision of the first service by the providing device is stopped during the predetermined processing, the second service corresponding to the first service is provided via a second protocol different from the first protocol. A determination step of determining whether the providing device provides the service of 2;
If it is determined that the providing device is providing the second service, a continuation step of continuing the predetermined process;
If it is determined that the providing device does not provide the second service, a stopping step of stopping the predetermined process;
A control method characterized by comprising:

The program for functioning a computer as a communication apparatus of any one of Claim 1 to 8.
