Abstract

According to an embodiment, an electronic device comprises: at least one communication processor configured to support first network communication and second network communication, wherein the at least one communication processor is configured to: receive a measurement command of at least one parameter associated with the second network communication based on the first network communication, identify whether a network communication other than the first network communication and the second network communication is activated, and based on identifying that the other network communication is activated, skip measurement on the at least one parameter associated with the second network communication.

First claim

What is claimed is:

1. An electronic device, comprising:
first communication circuitry configured to perform first network communication;
second communication circuitry configured to perform second network communication; and
at least one communication processor operatively coupled to the first and second communication circuitry and configured to support the first network communication and the second network communication, wherein the at least one communication processor is configured to:
receive, based on the first network communication, a measurement command of at least one parameter associated with the second network communication;
identify whether a third network communication other than the first network communication and the second network communication is activated:
in a case that the third network communication is identified as being activated, skip measurement on the at least one parameter associated with the second network communication; and
in a case that the third network communication is identified as being deactivated, measure the at least one parameter associated with the second network communication, and cause to report a result of the measured at least one parameter.

2. The electronic device of claim 1 , wherein the at least one communication processor is configured to:
form a connection of the second network communication based on a reporting of the at least one parameter and transmit and/or receive user data based on at least one of the first network communication or the second network communication;
identify activation of the third network communication while transmitting or receiving the user data based on at least one of the first network communication or the second network communication,
transmit a message for releasing the connection of the second network communication based on the identifying the activation of the third network communication.

3. The electronic device of claim 1 , wherein the at least one communication processor is further configured to:
transmit a connection request based on the first network communication and wherein the measurement command is received after transmitting the connection request.

4. The electronic device of claim 3 , wherein the at least one communication processor is configured to: transmit the connection request based on at least one of a request from an application executed on the electronic device, a request received via the first network communication, or an event of transmission of the connection request identified by the at least one communication processor.

5. The electronic device of claim 1 , wherein the at least one communication processor is configured to:
set up a voice over LTE (VoLTE) call based on the first network communication according to a request for the VoLTE call; and
receive a data radio bearer (DRB) release message including the measurement command based on at least one of the setup of the VoLTE call or a termination of the VoLTE call.

6. The electronic device of claim 1 , wherein the at least one communication processor is configured to receive a Radio Resource Control (RRC) connection reconfiguration message including the measurement command based on the first network communication.

7. An electronic device, comprising:
first communication circuitry configured to perform first network communication;
second communication circuitry configured to perform second network communication; and
at least one communication processor operatively coupled to the first and second communication circuitry and configured to support the first network communication and the second network communication, wherein the at least one communication processor is configured to:
receive, based on the first network communication, a measurement command of at least one parameter associated with the second network communication;
identify whether a third network communication other than the first network communication and the second network communication is activated;
identify whether a Packet Data Network (PDN) configured to use the second network communication, other than an Internet PDN configured based on the first network communication, is activated; and
skip measurement on the at least one parameter associated with the second network communication based on the third network communication being activated and no additional PDN being activated.

8. The electronic device of claim 7 , wherein the at least one communication processor is configured to: identify whether a PDN list activated on the electronic device includes a PDN meeting a preconfigured condition for at least one of a PDN identifier or a Quality-of-Service (QoS) Class Identifier (QCI).

9. The electronic device of claim 7 , wherein the at least one communication processor is configured to:
identify deactivation of the additional activated PDN while performing measurement on the at least one parameter associated with the second network communication, based on presence of the additional PDN activated; and
skip measurement of the at least one parameter associated with the second network communication based on identifying deactivation of the additional PDN.

10. The electronic device of claim 7 , wherein the at least one communication processor is configured to:
identify activation of the additional activated PDN while skipping measurement on the at least one parameter associated with the second network communication based on absence of the additional PDN activated; and
start measurement of the at least one parameter associated with the second network communication, based on identifying activation of the additional PDN.

11. The electronic device of claim 7 , wherein the at least one communication processor is configured to: based on the identifying activation of the additional PDN, start measurement on the at least one parameter based on the measurement command being identified as valid.

12. A method for operating an electronic device configured to support first network communication and second network communication, the method comprising:
receiving, based on the first network communication, a measurement command of at least one parameter associated with the second network communication;
identifying whether a third network communication other than the first network communication and the second network communication is activated;
in a case that the third network communication identified as activated, skipping measurement on the at least one parameter associated with the second network communication; and
in a case that the third network communication is identified as deactivated, measuring the at least one parameter associated with the second network communication and reporting a result of the measured at least one parameter.

13. The method of claim 12 , further comprising:
forming a connection of the second network communication based on a reporting of the at least one parameter and transmit and/or receive user data based on at least one of the first network communication or the second network communication;
based on identified activation of the third network communication while transmitting and/or receiving the user data based on at least one of the first network communication or the second network communication,
transmitting a message for releasing the connection of the second network communication based on the identified activation of the third network communication.

14. The method of claim 12 , wherein receiving the measurement command includes:
setting up a Voice over Long Term Evolution (LTE) (VoLTE) call based on the first network communication, based on a request for the VoLTE call; and
