Abstract:
The disclosure generally relates to preemptively searching and selecting LTE-Direct Expressions to maintain continuity in availing services via LTE-Direct and thereby support uninterrupted device-to-device (D2D) communication when a current LTE-Direct session experiences loss or degradation. For example, in various embodiments, a wireless device may establish a first D2D connection with a peer device to access a service shared at the peer device. The wireless device may further discover at least one alternate peer device sharing the service while the first D2D connection is active such that a second D2D connection with the at least one alternate peer device can be established in response to loss and/or degradation associated with the first D2D connection.
