For example, the processor 400 may estimate the time at which the electronic device 101 switches to the active state based on the paging time and the preparation time of the communication circuit 420 for transition to the active state. For example, the time when the electronic device 101 switches to the active state may include a time that is as far ahead of the paging time as the preparation time of the communication circuit 420.

For example, an operation to change the paging time may include a series of operations for updating at least one of PF or PO related to paging by updating identification information of the electronic device 101. According to one embodiment, the processor 400 determines the time at which the electronic device 101 switches to the active state if the time at which the electronic device 101 switches to the active state is within a specified reference range set based on the frame boundary. You can check the number of consecutive detections (e.g., number of detections) within this reference range. The processor 400 determines the paging point (e.g., PF and/or Alternatively, it may be determined that an operation to change PO) is performed.

As an example, a state that satisfies a specified update condition may include a state in which the number of consecutive detections (e.g., number of detections) within the reference range at which the electronic device 101 switches to the active state exceeds the specified reference number. You can. As an example, a state that does not satisfy the specified update condition may include a state in which the number of consecutive detections (e.g., number of detections) within the reference range at which the electronic device 101 switches to the active state is less than or equal to the specified reference number. there is.

According to one embodiment, when performing wireless communication through a first wireless network (e.g., NR), the processor 400 configures the communication circuit 420 to perform a re-registration procedure to update the paging time. ) can be controlled. For example, the paging point may be updated based on a temporary ID (e.g., 5G-S-TMSI (temporary mobile subscriber identity)) assigned from the network through a re-registration procedure. According to one embodiment, when performing wireless communication through a second wireless network (e.g., LTE), the processor 400 updates the paging time based on an attach procedure or a tracking area update (TAU) procedure.

The communication circuit 420 can be controlled. The processor 400 may update the paging time based on information related to IMSI (eg, accepted IMSI offset) included in the attach response or TAU response.

According to one embodiment, when the processor 400 updates the paging time point (e.g., PF and/or PO), the time point at which the electronic device 101 switches to the active state is set based on the frame boundary. You can check whether it is within the specified standard range. The processor 400 performs an operation to change the paging point in time (e.g., PF and/or PO) when the point in time at which the electronic device 101 switches to the active state is within a specified reference range set based on the frame boundary. The communication circuit 420 can be controlled to do so. For example, the processor 400 updates the paging time point (e.g., PF and/or PO), but determines that the time point at which the electronic device 101 switches to the active state is within a specified reference range set based on the frame boundary. If so, the communication circuit 420 can be controlled to perform an operation to change the paging point (eg, PF and/or PO) regardless of the number of detections.

According to one embodiment, when the processor 400 additionally updates the paging time point (e.g., PF and/or PO), the time point at which the electronic device 101 switches to the active state is within a specified reference range set based on the frame boundary. You can check whether it is included. If the time at which the electronic device 101 switches to the active state is within a specified reference range set based on the frame boundary, the processor 400 sets the electronic device 101 to the active state after a specified time (e.g., guard time). You can check whether the point of transition is within the specified reference range set based on the frame boundary. According to one embodiment, if the processor 400 determines that the point at which the electronic device 101 switches to the active state after a specified time is within a specified reference range set based on the frame boundary, the processor 400 determines that the point in time at which the electronic device 101 switches to the active state is within the specified reference range set based on the frame boundary, Thus, an operation can be performed to change the paging point of time. For example, the designated time may be varied based on the number of times it is detected that the time point at which the electronic device 101 switches to the active state falls within a designated reference range set based on a frame boundary.

According to one embodiment, when the processor 400 includes a plurality of subscriber identification modules 410, the processor 400 may check whether the communication circuit 420 supports communication related to the plurality of subscriber identification modules 410 at the same time. . According to one embodiment, the processor 400 performs communication related to the plurality of subscriber identification modules 410 at the same time based on the frequency band of the wireless communication associated with each of the plurality of subscriber identification modules 410. You can check whether it is supported. For example, the communication circuit 420 may simultaneously support some of the frequency bands supported by the electronic device 101 (or the communication circuit 410) due to constraints in the internal structure of the communication circuit 420. This may be limited. For example, processor 400 may configure wireless communications associated with a first subscriber identity module to use the B7 band of the second wireless communications network, and wireless communications associated with the second subscriber identity module to use the B38 band of the second wireless communications network. When used, it may be determined that wireless communication for the first subscriber identification module and the second subscriber identification module cannot be supported simultaneously. For example, processor 400 may configure wireless communications associated with a first subscriber identity module to use the N2 band of the first wireless communications network, and wireless communications associated with a second subscriber identity module to use the N25 band of the first wireless communications network. When used, it may be determined that wireless communication for the first subscriber identification module and the second subscriber identification module cannot be supported simultaneously.

According to one embodiment, when the processor 400 determines that the communication circuit 420 cannot support communication related to the plurality of subscriber identification modules 410 at the same time, the processor 400 operates the active period of the plurality of subscriber identification modules 410. You can check if there is at least some overlap. According to one embodiment, the processor 400 determines that when the wireless communication associated with the first subscriber identity module is in the RRC standby state or the RRC inactive state, the paging point of the wireless communication associated with the first subscriber identity module is with the second subscriber identity module. You can check whether it is included in the active section of related wireless communication.
