Systems, methods, and devices for smart V2X preemptive connection
Smart vehicle-to-everything (V2X) preemptive connections for emergency and/or potential accident scenarios. A V2X-enabled vehicle may determine a current route of the vehicle and high-risk areas through which the vehicle may travel (e.g., a hospital zone, high pedestrian traffic area, etc.). The vehicle may determine a distance (d) from a beginning of the high-risk area and begin establishing a V2X connection upon reaching the determined distance. The V2X-enabled vehicle may also, or alternatively, pre-emptively establish a V2X connection upon detecting an event initiative of an emergency, a hazardous situation, or a potential emergency. Examples of such events may include a sharp turn, a vehicle speed exceeding a speed threshold, a sudden acceleration or declaration, etc. A preemptive V2X connection may, for example, enable vehicles to begin communicating with one another faster in case of a threat, emergency, or unsafe conditions for vehicles in the area.
1 . A user equipment (UE), comprising:
a memory; and
one or more processors configured to, when executing instructions stored in the memory, cause the UE to:
determine a vehicle-to-everything (V2X) connection trigger, the V2X connection trigger comprising the UE arriving at a location that is a preemptive distance from a particular area;
monitor for the V2X connection trigger;
establish a V2X connection in response to detecting the V2X connection trigger; and
communicate, via the V2X connection, with another UE.
2 . The UE of claim 1 , wherein the UE comprises a vehicle control system of a vehicle.
3 . The UE of claim 1 , wherein the particular area is determined based on a travel route designated for the UE.
4 . The UE of claim 1 , wherein the particular area is determined based on a search area defined by a geographic radius.
5 . The UE of claim 1 , wherein the V2X connection trigger is subject to a refresh timer.
6 . The UE of claim 1 , wherein the V2X connection trigger is not subject to a refresh timer.
7 . The UE of claim 1 , wherein the UE is to maintain the V2X connection until detecting an expiration of a V2X connection timer.
8 . The UE of claim 1 , wherein the UE is to maintain the V2X connection until detecting an expiration of a V2X connection event.
9 . The UE of claim 8 , wherein the V2X connection event comprises a distance traveled by the UE.
10 . The UE of claim 1 , wherein the location has a risk level below a threshold and the particular area has a risk level above the threshold.
11 . The UE of claim 1 , wherein the particular area is outside a path along which the UE is traveling.
12 . A method performed by a user equipment (UE), the method comprising:
determining a vehicle-to-everything (V2X) connection trigger, wherein the V2X connection trigger comprises a change in motion of the UE that is associated with a risk level greater than a risk level of the UE prior to activation of the V2X connection trigger;
monitoring for the V2X connection trigger;
establishing a V2X connection in response to detecting the V2X connection trigger; and
communicating, via the V2X connection, with another UE.
13 . The method of claim 12 , wherein the UE comprises a vehicle control system of a vehicle.
14 . The method of claim 12 , wherein the change in motion of the UE comprises at least one of: a rate of change in direction of the UE, a change in center of gravity of the UE, an acceleration of the UE, or a deceleration of the UE.
15 . The method of claim 12 , wherein the V2X connection trigger is configured to activate in anticipation of the UE entering an emergency state with enough time for the UE to establish the V2X connection before the UE enters the emergency state.
16 . The method of claim 15 , wherein the communicating is in response to the UE entering the emergency state and notifies the other UE of the emergency state.
17 . A baseband processor configured to cause a user equipment (UE) to:
determine a vehicle-to-everything (V2X) connection trigger, wherein the V2X connection trigger is configured to activate in anticipation of the UE entering a state associated with a higher risk level than the UE is at during activation of the V2X connection trigger and with enough time for the UE to establish a V2X connection before the UE enters the state;
monitor for the V2X connection trigger;
establish the V2X connection in response to detecting the V2X connection trigger; and
communicate, via the V2X connection, with another UE.
18 . The baseband processor of claim 17 , wherein the V2X connection trigger comprises the UE arriving at a geographic location of a specified distance from an area associated with the higher risk level.
19 . The baseband processor of claim 18 , wherein the area is determined based on a travel route designated for the UE.
20 . The baseband processor of claim 17 , further configured to cause the UE to:
transition from an RRC_idle state to an RRC_connected state in response to detecting the V2X connection trigger.
