Abstract:
1. A communication apparatus compatible with a first communication standard and a second communication standard being different from the first communication standard, the communication apparatus comprising: a participating unit configured to participate in a wireless network compatible with the first communication standard, the wireless network having been established in advance by a first other communication device which is not compatible with the second communication standard; a determining unit configure to determine that other communication device being not compatible with the second communication standard including at least the first other communication device has left the wireless network in which the communication apparatus is participating; and an establishing unit configured to leave the wireless network compatible with the first communication standard in responding to a result of a determination of the determining unit, and newly establish a wireless network compatible with the second communication standard; a transmission unit configured to transmit a switching signal which indicates switching from a wireless network compatible with the first communication standard to a network compatible with the second communication standard; and a judging unit configured to judge whether or not other communication device compatible with the second communication standard rejects the switching from a wireless network compatible with the first communication standard to a network compatible with the second communication standard based on a response to the switching signal, from the other communication device compatible with the second communication standard, wherein the establishing unit newly establishes a wireless network compatible with the second communication standard when the other communication device compatible with the second communication standard does not reject the switching from a wireless network compatible with the first communication standard to a network compatible with the second communication standard.
