Filed:

Mar 3, 2021

Appl. No.:

17/191316

Inventors:

- Chicago IL, US
Si Chen - Chicago IL, US

Assignee:

Motorola Mobility LLC - Chicago IL

International Classification:

H04W 36/00
H04W 76/19
H04W 4/029

Abstract:

Techniques for multiple call types for a call event are described and may be implemented via a wireless device to enable multiple connections for wireless calls. For instance, redundant connections for a call event of a wireless device are established via different call types and utilized to exchange call media of the call event. In at least some implementations, call media from the different call types is combined to provide a combined media stream for output as part of the call event. Thus, techniques for multiple call types for a call event are applicable to increase call quality in different scenarios and environments, such as in situations where a primary call connection experiences an anomaly condition that causes quality call degradation.

International Classification:

H04W 76/19
H04W 4/029

Abstract:

Techniques for call type selection based on failure probability are described and may be implemented via a wireless device to adapt to a variety of different wireless scenarios. Generally, the described techniques provide a wireless device with the ability to implement a wireless call event via different call types, e.g., different radio access technologies (RATs). For instance, when a first call type frequently experiences failure at a particular location, a second call type is utilized to initiate calls at the location, such as based on call records for historic call events.

International Classification:

G05D 1/02
G05D 1/00
H04W 4/024

Abstract:

A method, a communication device and a computer program product for navigating to a location with communications to a wireless network. The method includes detecting, via a processor of a communication device, a loss of a first communication signal from a wireless network and receiving signal loss location data corresponding to a first location where the first communication signal from the wireless network was lost. The method further includes retrieving, from a memory of the communication device, first navigation data corresponding to a first route between a starting location and an end location. The method further includes generating and presenting, on an output device of the communication device, second navigation data based on the first navigation data and the signal loss location data. The second navigation data corresponds to a second route between a current location and the first location where communications to the wireless network are available.

International Classification:

H04W 36/12
H04W 36/16

Abstract:

Techniques for call recovery for call failure are described and may be implemented via a wireless device to adapt to a variety of different wireless scenarios. For instance, when multiple call failures for a call occur over a particular set of radio access technologies, an IP-based call and/or a direct device-to-device call can be implemented to complete the call.

Abstract:

Techniques for optimal device position for wireless communication are described, and may be implemented via a mobile device to identify an orientation in which to place a mobile device to achieve optimum wireless signal. Generally, the described techniques enable the mobile device to be dynamically calibrated for wireless communication by identifying signal attributes at multiple different device positions, and enabling the mobile device to be placed at a position that exhibits optimum wireless signal. Further, wireless tasks to be performed on a mobile device can be placed into a task queue and executed when the mobile device is detected at a location and/or position that exhibits optimum wireless signal.

Abstract:

Techniques for process based antenna configuration are described, and may be implemented via a wireless device to identify different usage scenarios and to adapt antenna configurations to optimize wireless performance based on the scenarios. For instance, the described techniques enable a wireless device to be calibrated for wireless communication by identifying different obstruction states of a wireless device that correspond to ways that the wireless device is held (e.g., grasped) by a user in different scenarios. The obstruction states are then correlated to antenna positions in the wireless device to prioritize (e.g., activate) antennas that are relatively unobstructed, such as by activating unobstructed antennas and/or deactivating obstructed antennas. Further, calibration can take into specific processes (e.g., applications) and specific users to calibrate an optimize wireless performance based on ways in which a user typically interacts with a process.
