Abstract

A communication device includes a recognition unit configured to recognize a service provided by a network, a generation unit configured to generate a packet to be transmitted to an external device that provides the service recognized by the recognition unit based on a priority set to the packet according to the recognized service when the service is recognized by the recognition unit, and a connection unit configured to establish a connection with the external device using the packet generated by the generation unit.

Claims

1. A communication device comprising:

a recognition unit configured to recognize a service, using a first priority higher than a second priority, provided by an external device;

a generation unit configured to generate a packet to be transmitted to the external device and to which the first priority is set, in a case that the service is recognized by the recognition unit; and

a connection unit configured to establish a connection with the external device using the packet generated by the generation unit,

wherein the generation unit is further configured to generate a packet to be transmitted to the external device and to which the second priority is set, in a case that no service is recognized by the recognition unit.

2. The communication device according to claim 1, further comprising:

a search unit configured to search for a service from a network,

wherein the recognition unit recognizes the service using the first priority.

3. The communication device according to claim 1, wherein the recognition unit recognizes one of a deletion or an appearance of the service.

4. The communication device according to claim 1, further comprising:

a transmission unit configured to send the packet generated by the generation unit to the external device after the connection by the connection unit.

5. A method for controlling a communication device, the method comprising:

recognizing a service, using a first priority higher than a second priority, provided by an external device;

generating a packet to be transmitted to the external device and to which the first priority is set, in a case that the service is recognized;

generating a packet to be transmitted to the external device and to which the second priority is set, in a case that no service is recognized; and

connecting with the external device using the generated packet.

6. A non-transitory storage medium storing a computer-executable program, which, when executed by a computer, causes the computer to perform a method for controlling a communication device, the method comprising:

recognizing a service, using a first priority higher than a second priority, provided by an external device;

generating a packet to be transmitted to the external device and to which the first priority is set, in a case that the service is recognized;

generating a packet to be transmitted to the external device and to which the second priority is set, in a case that no service is recognized; and

connecting with the external device using the generated packet.
