Analyzing device information to proactively request attachment to a non-standalone architecture node with minimum signaling associated with a telecommunication signal
A computer-implemented method according to one embodiment includes collecting device information from at least a first device, and receiving, from the first device, a first request to attach to a first base station. In response to receiving the first request, it is determined whether a signal broadcasted from the first base station includes public land mobile network (PLMN) information of a first type of telecommunication signal. In response to a determination that the signal broadcasted from the first base station includes the PLMN information, a second request is sent to a core network to connect the first device to a node associated with the first type of telecommunication signal of the first base station. In response to receiving an indication that the first device is authorized to connect, a connection is allowed to be established between the first device and the node associated with the first type of telecommunication signal.
