Abstract

An electronic device is provided. The electronic device includes a first communication processor and a second communication processor, the second communication processor is configured to receive, from the first communication processor, a first report condition for measurement information for a signal from at least one which corresponds to a second network communication, identify a second report condition which corresponds to connection failure of the electronic device to a first base station corresponding to the second network communication, and transfer the first measurement information to the first communication processor, and the first communication processor is configured to transmit, to a base station corresponding to a first network communication, the first measurement information received from the second communication processor.

First claim

What is claimed is:

1. An electronic device comprising:
a first communication processor configured to support a first network communication with a first network; and
a second communication processor configured to support a second network communication with a second network different from the first network,
wherein the second communication processor is further configured to:
receive, from the first communication processor, a first report condition for measurement information for a signal from at least one base station corresponding to the second network communication, wherein the first communication processor identifies the first report condition based on a message received from a base station supporting the first network communication before a connection between a first base station corresponding to the second network communication and the electronic device through the second network communication is established,
identify a second report condition corresponding to a connection failure of the electronic device to the first base station corresponding to the second network communication,
based on an identification of the connection failure to the first base station, in a case that first measurement information for a signal from the first base station satisfies the second report condition, transfer the first measurement information to the first communication processor, and
based on the connection failure to the first base station not being identified, in a case that the first measurement information for the signal from the first base station satisfies the first report condition, transfer the first measurement information to the first communication processor, and

wherein the first communication processor is further configured to transmit, to the base station corresponding to the first network communication for establishment of the first base station and the electronic device through the second network communication, the first measurement information received from the second communication processor.

2. The electronic device of claim 1 , wherein the second communication processor is further configured based on the identification of the connection failure to the first base station, in a case that the second report condition is not satisfied, refrain from transferring the first measurement information to the first communication processor.

3. The electronic device of claim 1 , wherein the second communication processor is further configured to, based on the identification of the connection failure to the first base station, in a case that the second report condition is not satisfied and the first report condition is satisfied, refrain from transferring the first measurement information to the first communication processor.

4. The electronic device of claim 1 ,
wherein the first report condition indicates whether a value of the first measurement information is greater than a first threshold value, and
wherein the second report condition indicates whether the value of the first measurement information is greater than a second threshold value different from the first threshold value.

5. The electronic device of claim 4 , wherein the second communication processor is further configured to set, as the second threshold value, one of measurement information reported in response to the connection failure to the first base station or a value calculated from the measurement information reported in response to the connection failure.

6. The electronic device of claim 4 , wherein the second communication processor is further configured to set a value calculated from the first threshold value as the second threshold value.

7. The electronic device of claim 1 , wherein the second communication processor is further configured to, as at least part of the transferring of the first measurement information to the first communication processor, based on the first measurement information satisfying the second report condition and a number of connection failures to the first base station being greater than or equal to a threshold count, transfer the first measurement information to the first communication processor.

8. The electronic device of claim 1 , wherein the second communication processor is further configured to, based on the identification of the connection failure to the first base station, in a case that the first measurement information does not satisfy the second report condition, transfer the first measurement information to the first communication processor in response to identifying that a value of the first measurement information is greater than a specified third threshold value.

9. The electronic device of claim 1 , wherein the second communication processor is further configured to:
as at least part of the transferring of the first measurement information to the first communication processor in a case that the first measurement information satisfies the second report condition during a specified time duration and based on the identification of the connection failure to the first base station, transfer the first measurement information to the first communication processor, and
in response to the specified time duration elapsing, in a case that the first measurement information for the signal from the first base station having a history of connection failures satisfies the first report condition, transfer the first measurement information to the first communication processor.

10. An electronic device comprising:
a first communication processor configured to support a first network communication with a first network; and
a second communication processor configured to support a second network communication with a second network different from the first network,
wherein the second communication processor is further configured to:
receive, from the first communication processor, a first report condition for measurement information for a signal from at least one base station corresponding to the second network communication, wherein the first communication processor identifies the first report condition based on a message received from a base station supporting the first network communication before a connection between a first base station corresponding to the second network communication and the electronic device through the second network communication is established,
identify a second report condition corresponding to a connection release of the electronic device from the first base station corresponding to the second network communication,
based on an identification of the connection release from the first base station after establishing a connection to the first base station, in a case that first measurement information for a signal from the first base station satisfies the second report condition, transfer the first measurement information to the first communication processor, and
based on the connection release from the first base station not being identified, in a case that the first measurement information for the signal from the first base station satisfies the first report condition, transfer the first measurement information to the first communication processor, and

wherein the first communication processor is further configured to transmit, to the base station corresponding to the first network communication for establishment of the first base station and the electronic device through the second network communication, the first measurement information received from the second communication processor.

11. The electronic device of claim 10 , wherein the second communication processor is further configured based on the identification of the connection release from the first base station, in a
