Problems solved by technology

However, this can consume power from the device, which can become a concern, especially if the user is not located near a power source
In addition, sometimes the link quality of the device may be low, resulting in signal degradation, which may negatively affect the user's communication experience

Embodiment Construction

[0027] Various aspects are now described with reference to the figures. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that these aspects may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing these aspects.

[0028] see figure 1, which depicts a system 100 that supports inter-device handover, according to one aspect. In one example, when people are using mobile devices such as phones to communicate (e.g., voice calls, data calls, applications such as social networking, email, browsers, etc.) while walking from an office building to a personal vehicle, Switching between devices may occur. As the person (and the mobile device) approaches the vehicle (or at roughly the same time as the vehicle's engine is started), c...

Abstract

Some aspects describe inter-device handover without infrastructure assistance. The present application discloses a method for inter-device switching performed by a wireless communication device. The present application discloses a wireless communication device for performing inter-device handover without network assistance. The present application discloses a computer program product comprising a computer readable medium comprising code for performing inter-device switching. The present application discloses at least one processor configured to perform a non-network assisted communication handover.

Description

technical field [0001] The description that follows relates generally to wireless communications and, more specifically, to shared wireless wide area network modems. Background technique [0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, data, video, etc., in order to communicate regardless of where the user is located (e.g., inside or outside a structure) and whether the user is stationary or moving (e.g., , transmitting information while in a vehicle, walking). These systems may be multiple-access systems that can support communication with multiple users by sharing available system resources (eg, bandwidth and transmit power). Multiple access systems include Frequency Division Multiple Access (FDMA) systems, Time Division Multiple Access (TDMA) systems, Code Division Multiple Access (CDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Third Generation Partnership Project ...
