Abstract

The present disclosure proposes a network diversity based error reporting method and a user equipment using the same method. The user equipment using the proposed method in the event of a network error would establish a first connection with a first network, establish a second connection with a second network which is a different type of network from the first network, establish a first failure report corresponding to the first connection in response to failing to connect with the first network, transmit through the second connection the first failure report to the second network in response to establishing the first failure report, establish a second failure report corresponding to the second connection in response to failing to connect with the second network, and transmit through the first connection the second failure report to the first network in response to establishing the second failure report.

establishing a first connection with a first network;

establishing a second connection with a second network which is a different type of network from the first network;

establishing a first failure report corresponding to the first connection in response to failing to connect with the first network;

transmitting through the second connection the first failure report to the second network in response to establishing the first failure report;

establishing a second failure report corresponding to the second connection in response to failing to connect with the second network; and

transmitting through the first connection the second failure report to the first network in response to establishing the second failure report.

2. The method of claim 1, wherein the first network is a wireless local area network (WLAN) and the second network is a cellular network, and after the step of establishing the second connection with the second network, claim 1 further comprises:

transmitting wireless data through the first connection using the WLAN; and

transmitting wireless data through the second connection using the cellular network.

3. The method of claim 2, wherein the first failure report comprises a location information and a signal source information, wherein the location information of the first failure report comprises a basic service set identification (BSSID) and the signal source information of the first failure report comprises a signal strength and a signal quality information.

4. The method of claim 1, wherein the step of establishing the second failure report further comprises:

measuring from a neighboring cell to gather a cellular information comprising an operating frequency, a measured signal strength, and a measured signal quality of the neighboring cell.

5. The method of claim 4, wherein the second failure report further comprises the cellular information of the neighboring cell, a location information, and a signal source information wherein the location information of the second failure report comprises a physical cell identifier and the signal source information of the second failure report comprises a signal strength and a signal quality information.

6. The method of claim 1, wherein the step of establishing the second connection with the second network further comprises:

receiving a first signaling request from the first network which is a WLAN to connect to the second network which is a cellular network; and

initiating the second connection to the cellular network in response to the first signaling request while maintaining the first connection.

7. The method of claim 6, wherein the step of failing to connect with the first network is determined when a signal strength or a signal quality of the first network is below a non-zero threshold.

8. The method of claim 7, wherein transmitting through the second connection the first failure report to the second network in response to establishing the first failure report further comprises:

transmitting the first failure report through the first connection to the first network.

9. The method of claim 1, wherein the step of establishing the first connection with the first network further comprises:

receiving a second signaling request from the second network which is a cellular network to connect to the first network which is a WLAN; and

initiating the first connection to the WLAN in response to the second signaling request while maintaining the second connection.

10. The method of claim 9, wherein the step of failing to connect with the second network is determined when a signal strength or a signal quality of the second network is below a non-zero threshold during a RRC measurement event.

11. The method of claim 10, wherein transmitting through the first connection the second failure report to the first network in response to establishing the second failure report further comprises:

transmitting the second failure report through the second connection to the second network.
