摘要

A communication apparatus receives, from a first apparatus which has established a communication session, a signal indicating a state in which the communication session should be maintained. If the signal is not received from the first apparatus within a predetermined period of time while the communication session with the first apparatus is established, and a communication session establishment request is received from a second apparatus, the communication apparatus disconnects the communication session with the first apparatus.

1. A communication apparatus comprising:
a CPU coupled to a memory, wherein the CPU performs control of a reception unit and a control unit; the reception unit receiving, from a first apparatus which has established a communication session, a control signal indicating a state in which the communication session should be maintained, wherein the control signal is different from a signal including non-control data to be transmitted from the first apparatus to the communication apparatus; and the control unit disconnecting the communication session with the first apparatus, if the control signal is not received from the first apparatus within a predetermined period of time while the communication session with the first apparatus is established, and a communication session establishment request is received from a second apparatus, regardless of whether or not the signal including non-control data is received within the predetermined period, wherein the control unit does not disconnect the communication session with the first apparatus, if the request is not received from the second apparatus regardless of whether or not the control signal is received within the predetermined period of time.
