The temperature measured by the temperature sensor 610 may include the temperature of a part of the electronic device 101 in which the temperature sensor 610 is disposed. The application processor 620 may check whether the temperature measured by the temperature sensor 610 satisfies a specified condition. The specified condition may include a condition in which the temperature measured by the temperature sensor 610 is equal to or greater than (or exceeds) a specified value (eg, 35.5 degrees).

The communication processor 640 may perform one or more operations for releasing the RRC connection of the first cellular communication. According to an embodiment, the communication processor 640 is set to report when the strength of a signal transmitted by a node connected through the first cellular communication (eg, the first node 450 of FIG. 5A) is smaller than a specific value. An A2 event measurement report (A2 measurement report) may be transmitted. The A2 event measurement report transmitted by the communication processor 640 may be transmitted regardless of the strength of a signal transmitted (or broadcasted) by the node 450 connected through the first cellular communication. For example, the communication processor 640 may transmit the A2 event measurement report in a situation where the strength of a signal transmitted by the node 450 connected through the first cellular communication is higher than a specific value.

Upon receiving the A2 event measurement report, the first cellular communication network (eg, the second network 294 of FIG. 2 ) may determine whether to release the first cellular communication according to whether the A2 event measurement report is received. The first cellular communication network 294 may receive the A2 event measurement report and release the RRC connection between the electronic device 101 and the first cellular communication network 294 .

The SCGF transmitted by the communication processor 640 may be transmitted regardless of the strength of a signal transmitted (or broadcasted) by the node 450 connected through the first cellular communication. The first cellular communication network 294 may receive the SCGF and release the RRC connection between the electronic device 101 and the first cellular communication network 294 .

The communication processor 640 may perform relatively faster release of the first cellular communication by transmitting the SCGF without the A2 event measurement report.

The communication processor 640 may perform a series of operations for maintaining RR release of the first cellular communication after the release of the first cellular communication is completed.

Upon receiving the B1 event measurement report, the network of the first cellular communication (eg, the second network 294 of FIG. 2 ) may determine whether to connect the RRC connection of the first cellular communication according to whether or not the B1 event measurement report is received. there is. When the B1 event measurement report is received, the first cellular communication network 294 may perform an RRC connection between the electronic device 101 and the first cellular communication network 294 again. Accordingly, the communication processor 640 may maintain the release state of the first cellular communication by not transmitting the B1 event measurement report.

Although the embodiment described above describes releasing and/or maintaining the RRC connection of the first cellular communication based on throughput and/or temperature, the electronic device 101 is not limited to throughput and/or temperature. However, the RRC connection of the first cellular communication may be released and/or maintained in consideration of various conditions.

The list of applications may be generated based on a user's selection of the electronic device 101, or may be received from a server (eg, the electronic device 104 of FIG. 1) existing outside the electronic device 101. .

Alternatively, the list of applications may be generated based on characteristics of services provided by the applications. For example, as the connected cellular communication of the electronic device 101 is switched, an application providing a service that is difficult to perform smoothly (eg, voice over NR (VoNR)) may be included in the list of applications.

When the application processor 620 detects an inactive state of the display 630 while an application included in the list of applications for which release of the RRC connection of the first cellular communication is prohibited is running, the throughput and/or temperature are specified. Regardless of whether the condition is satisfied, the connection of the first cellular communication may be maintained without disconnecting the first cellular communication.

According to another embodiment, the electronic device 101 temporarily and/or non-temporarily stores a list of applications for which disconnection of the first cellular communication is permitted (eg, the memory 130 of FIG. 1 ) can include The list of applications may be generated based on a user's selection of the electronic device 101, or may be received from a server (eg, the electronic device 104 of FIG. 1) existing outside the electronic device 101. .

Alternatively, the list of applications may be generated based on characteristics of services provided by the applications. For example, as the connected cellular communication of the electronic device 101 is switched, an application that provides a service capable of performing a smooth service (eg, a streaming service that uses a method of receiving data at designated time intervals) is an application of the application. may be included in the list.

The application processor 620 determines that the inactive state of the display 630 is longer than a specified time while the application included in the list of applications allowed to release the first cellular communication is running, and the throughput and/or temperature A series of operations for releasing the RRC connection of the first cellular communication may be performed in response to checking whether or not satisfies the specified condition and that the throughput and/or temperature satisfy the specified condition.

The electronic device 101 may support both the embodiment described in the description of FIG. 6 and the embodiment described in the description of FIG. 5B.

The application processor 620 may detect that the display 630 is deactivated and check whether the throughput satisfies a specified condition. In response to the throughput satisfying a specified condition, disconnection of the first cellular communication may be waited for.

Disconnection of the first cellular communication is performed by data (eg, 10 seconds) for a specified time (eg, 10 seconds) of a timer (eg, RRC inactivity timer) of the network (eg, the second network 294 of FIG. 2 ) of the first cellular communication. Alternatively, it may be performed when transmission and/or reception of a packet) does not occur.

As the application processor 620 receives information indicating that the first cellular communication is disconnected from the communication processor 640, it may not check whether throughput and/or temperature satisfy specified conditions.

If the application processor 620 does not receive information indicating that the connection of the first cellular communication is disconnected, the application processor 620 checks whether the throughput and/or temperature satisfy specified conditions, and the throughput and/or temperature meet the specified conditions. If satisfied, a series of operations for disconnection of the first cellular communication (eg, A2 measurement report transmission and/or SCGF transmission) may be performed.
