A system is configured to receive an indication that a connection with a user device is to be lost, the connection being associated with a call between the user device and another user device; provide an instruction, to one or more devices, to maintain the call when the connection is lost, the one or more devices being responsible for processing the call; detect that the connection is lost; provide, to the one or more devices, a first notification that the connection is lost, the first notification causing the one or more devices to maintain the call based on the instruction to maintain the call when the connection is lost; detect that the connection is re-established; and provide, to the one or more devices, a second notification that the connection is re-established, the second notification causing the one or more devices to re-establish the call. |

1. A method comprising:
determining, by a device, that a connection with a first user device is to be lost,
the connection being associated with a call between the first user device and a second user device; providing, by the device and based on determining that the connection with the first user device is to be lost, an instruction, to one or more devices, to maintain the call when the connection is lost,
the one or more devices being responsible for processing the call,the instruction causing the one or more devices to not terminate at least one of signaling or protocols that are used to maintain the call when the connection is lost, andthe one or more devices including one or more of a base station, a serving gateway, or a packet data network (PDN) gateway; detecting, by the device, that the connection is lost; providing, by the device and to the one or more devices, a first notification indicating that the connection is lost,
the first notification causing the one or more devices to maintain the call based on the instruction to maintain the call when the connection is lost; detecting, by the device, that the connection is re-established; and providing, by the device and to the one or more devices, a second notification indicating that the connection is re-established,
the second notification causing the one or more devices to re-establish the call between the first user device and the second user device. |
