1. A method, comprising:
determining, by a device, that a user device associated with a first location is located in a second location,
the first location being associated with an initial packet data network gateway (PGW) of a provider network,
the second location being associated with a target PGW of the provider network;
determining, by the device, that the user device moved from being located at the first location to being located at the second location that is at least a threshold distance from the first location;
wherein the user device is located at the second location for a threshold amount of time;
determining, by the device and based on determining that the user device is located at the second location for the threshold amount of time, that the user device is to be handed off from a first connection with the initial PGW to a second connection with the target PGW; and
causing, by the device, one or more bearers associated with the first connection to be dropped and one or more bearers associated with the second connection to be established, based on determining that the user device moved from being located at the first location to being located at the second location that is at least at the threshold distance from the first location and for the threshold amount of time,
the user device remaining connected to the provider network when disconnecting from the initial PGW and connecting to the target PGW,
the target PGW being established without an initial startup,
the first connection being dropped and the second connection being established after the user device finishing streaming network traffic via the initial PGW, and
the first connection being dropped and the second connection being established prior to finishing the streaming of the network traffic via the initial PGW based on a threshold reduction in network performance.
