Communication apparatus, control method, and storage medium

A control method to be executed by a communication apparatus that executes concurrent communication with a first base station and a second base station based on Dual Connectivity (DC) defined in cellular communication standards, the first base station operating as a master node in the DC and the second base station operating as a secondary node in the DC, the control method comprising:

• in a case where the state of the communication apparatus has transitioned from an RRC_Inactive state to an RRC_Connected state while settings related to the DC are maintained and connection processing to both the first base station and the second base station is performed, controlling the state of the communication apparatus to maintain the RRC_Connected state in a case where connection processing for establishing a connection to the first base station is successful but connection processing for establishing a connection to the second base station is unsuccessful.

A non-transitory computer-readable storage medium storing therein a program for causing a computer that is included in a communication apparatus to control the state of the communication apparatus that is that executes concurrent communication with a first base station and a second base station based on Dual Connectivity (DC) defined in cellular communication standards of the Third Generation Partnership Project, the first base station operating as a master node in the DC and the second base station operating as a secondary node in the DC,

• wherein the state of the communication apparatus is controlled such that, in a case where the state of the communication apparatus has transitioned from an RRC_Inactive state to an RRC_Connected state while settings related to the DC are maintained and connection processing to both the first base station and the second base station is performed, the RRC_Connected state is maintained in a case where connection processing for establishing a connection to the first base station is successful but connection processing for establishing a connection to the second base station is unsuccessful.
