Communication apparatus and method providing robust service in the presence of deteriorated radio conditions

摘要

Data communication using wireless service discovery is continuously provided even if a radio wave condition temporarily deteriorates or movement of an apparatus occurs. If a temporary deterioration in wireless radio wave environment is found in a communication apparatus including a service discovery function, a search is made again at a raised transmission power. Forcible disconnection processing from a higher-level layer is prevented when communication at the network layer level is ongoing.
