System and method for indicating coverage types for user devices in dual connectivity wireless networks
Systems and methods described herein improve a customer experience for non-standalone celular networks by displaying a secondary cell group (SCG) network icon after data activity ends while a user device likely remains in SCG coverage. When connected to the SCG, the user device detects inactivity on the connection and initiates a first timer, based on the detecting, while continuing to present an SCG-related icon. If the first timer expires while the user device is in an idle state, the user device initiates a second timer, while continuing to present the SCG-related icon. If the user device detects an active connection before expiration of the second timer, the user device initiates a third timer while continuing to present the SCG-related icon. If the user device fails to detect a connection to the SCG before expiration of the third timer, a master cell group (MCG)-related icon is displayed.
1. A user device comprising:
a communication interface;
a memory storing instructions; and
one or more processors configured to execute the instructions to:
establish a connection to one or more secondary cell groups (SCGs) in a wireless network;
present, in response to the establishing, a SCG-related network icon on the user device;
detect inactivity on the connection to the one or more SCGs;
initiate a first timer, based on the detecting, while continuing to present the SCG-related network icon;
initiate a second timer, while continuing to present the SCG-related network icon, if the first timer expires while the user device is in an idle state;
detect, before expiration of the second timer, an active connection with a master cell group (MCG);
initiate a third timer in response to detecting the active connection with the MCG and while continuing to present the SCG-related network icon; and
switch presentation of the SCG-related network icon to presentation of a MCG-related network icon when the third timer expires and the user device is not connected to one of the SCGs.
2. The user device of claim 1 , wherein detecting the inactivity includes detecting a radio link failure with the SCG or expiration of a network inactivity timer.
3. The user device of claim 1 , wherein one or more of the first timer, the second timer, and third timer have configurable intervals.
4. The user device of claim 1 , wherein the second timer includes a second configurable time interval that is larger than a first configurable time interval of the first timer.
5. The user device of claim 4 , wherein the third timer includes a third configurable time interval that is less than the second configurable time interval.
6. The user device of claim 1 , wherein the SCG includes a next generation Node B using millimeter wave (mmWave) radio frequencies.
7. The user device of claim 1 , wherein the MCG includes a wireless station for a Long Term Evolution network.
8. The user device of claim 1 , wherein the one or more processors are further configured to execute the instructions to:
switch presentation of the SCG-related network icon to presentation of the MCG-related network icon when the second timer expires while the user device is in the idle state.
9. The user device of claim 1 , wherein at least one of the one or more processors in included in a modem of the user device.
10. The system of claim 1 , wherein at least one of the one or more processors further executes an operating system of the user device.
11. A method performed by a user device, the method comprising:
establishing a connection to one or more secondary cell groups (SCGs) in a wireless network;
presenting, in response to the establishing, a SCG-related network icon on the user device;
detecting inactivity on the connection to the one or more SCGs;
initiating a first timer, based on the detecting, while continuing to present the SCG-related network icon;
initiating a second timer, while continuing to present the SCG-related network icon, if the first timer expires while the user device is in an idle state;
detecting, before expiration of the second timer, an active connection with a master cell group (MCG);
initiating a third timer in response to detecting the active connection with the MCG and while continuing to present the SCG-related network icon; and
switching presentation of the SCG-related network icon to presentation of a MCG network icon when the third timer expires and the user device is not connected to one of the SCGs.
12. The method of claim 11 , wherein detecting the inactivity includes detecting a radio link failure with the SCG or expiration of a network inactivity timer.
13. The method of claim 11 , wherein the second timer includes a configurable time interval of more than about 60 seconds, and wherein the third timer includes a configurable time interval of between about 0 to about 4 seconds.
14. The method of claim 11 , wherein the first timer includes a configurable time interval of at least about 3 seconds.
15. The method of claim 11 , wherein the SCG includes a next generation Node B using millimeter wave (mmWave) radio frequencies.
16. The method of claim 11 , wherein the MCG includes a wireless station for a Long Term Evolution network.
17. The method of claim 11 , further comprising:
switching presentation of the SCG-related network icon to presentation of the MCG-related network icon when the second timer expires while the user device is in the idle state.
18. A non-transitory, computer-readable storage media storing instructions executable by one or more processors of a user device, which when executed cause the user device to:
establish a connection to one or more secondary cell groups (SCGs) in a wireless network;
present, in response to the establishing, a SCG-related network icon on the user device;
detect inactivity on the connection to the one or more SCGs;
initiate a first timer, based on the detecting, while continuing to present the SCG-related network icon;
initiate a second timer, while continuing to present the SCG-related network icon, if the first timer expires while the user device is in an idle state;
detect, before expiration of the second timer, an active connection with a master cell group (MCG);
initiate a third timer in response to detecting the active connection with the MCG and while continuing to present the SCG-related network icon; and
switch presentation of the SCG-related network icon to presentation of a MCG-related network icon when the third timer expires and the user device is not connected to one of the SCGs.
19. The non-transitory, computer-readable storage media of claim 18 , wherein the MCG includes a wireless station for a Long Term Evolution network, and wherein the SCG includes a next generation Node B using millimeter wave (mmWave) radio frequencies.
20. The non-transitory, computer-readable storage media of claim 19 , wherein the instructions, when executed, further cause the user device to:
switch presentation of the SCG-related network icon to presentation of the MCG-related network icon when the second timer expires while the user device is in the idle state.
