Communication apparatus, control method, and storage medium
A communication apparatus includes a transition unit and a control unit. In a case where a wireless communication path to each of a first base station and a second base station is established, the transition unit transitions from an RRC_CONNECTED state to an RRC_INACTIVE state compliant with a 3rd Generation Partnership Project (3GPP) standard. In a case where the transition unit transitions to the RRC_INACTIVE state, the control unit performs control to selectively execute operating in a first mode for waiting for a notification signal from each of the first and second base stations or operating in a second mode for waiting for a notification signal from either the first base station or the second base station, based on a state of the communication apparatus.
1. A communication apparatus comprising:
one or more memories having instructions stored therein; and
one or more processors that, upon execution of the instructions, are configured to:
after a wireless communication path to each of a first base station and a second base station is established, transition from an RRC_CONNECTED state to an RRC_INACTIVE state compliant with a 3rd Generation Partnership Project standard; and
after transitioning to the RRC_INACTIVE state, perform control to select a mode from a first mode in which the communication apparatus is configured to receive a notification signal from each of the first and second base stations and a second mode in which the communication apparatus is configured to receive a notification signal from either one of the first base station and the second base station while not receiving a notification from the other one of the first base station and the second base station,
wherein the selection is made based on a state of the communication apparatus.
2. The communication apparatus according to claim 1 ,
wherein the first base station is a base station for a master cell compliant with the 3rd Generation Partnership Project standard, and
wherein the second base station is a base station for a secondary cell.
3. The communication apparatus according to claim 1 , wherein the selection is made based on a movement state of the communication apparatus.
4. The communication apparatus according to claim 1 , wherein the one or more processors is further configured to determine whether the communication apparatus is moving,
wherein, in a case where the communication apparatus is determined to be moving, the first mode is selected.
5. The communication apparatus according to claim 1 , wherein the selection is made based on a power supply state of the communication apparatus.
6. The communication apparatus according to claim 1 , wherein the selection is made based on a service provided by the communication apparatus.
7. The communication apparatus according to claim 1 , wherein the communication apparatus establishes the wireless communication path to each of the first and second base stations using a dual connectivity function compliant with the 3rd Generation Partnership Project standard.
8. The communication apparatus according to claim 1 , wherein the notification signal is a paging channel signal compliant with the 3rd Generation Partnership Project standard.
9. The communication apparatus according to claim 1 , wherein the selection is made periodically.
10. A control method for controlling a communication apparatus, the control method comprising:
transitioning, after a wireless communication path to each of a first base station and a second base station is established, from an RRC_CONNECTED state to an RRC_INACTIVE state compliant with a 3rd Generation Partnership Project standard; and
performing control to, after transitioning to the RRC_INACTIVE state, select a mode from a first mode in which the communication apparatus is configured to receive a notification signal from each of the first and second base stations and a second mode in which the communication apparatus is configured to receive a notification signal from either one of the first base station and the second base station while not receiving a notification from the other one of the first base station and the second base station,
wherein the selection is made based on a state of the communication apparatus.
11. A non-transitory computer-readable storage medium storing a computer program for causing a computer to execute a method comprising:
transitioning, after a wireless communication path to each of a first base station and a second base station is established, from an RRC_CONNECTED state to an RRC_INACTIVE state compliant with a 3rd Generation Partnership Project standard; and
performing control to, after transitioning to the RRC_INACTIVE state, select a mode from a first mode in which the communication apparatus is configured to receive a notification signal from each of the first and second base stations and a second mode in which the communication apparatus is configured to receive a notification signal from either one of the first base station and the second base station while not receiving a notification from the other one of the first base station and the second base station,
wherein the selection is made based on a state of the communication apparatus.
