Patent ID: 11871294
Assignee: T-MOBILE USA, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 5:
6. A system, comprising:
one or more processors; and
one or more non-transitory computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the system to perform actions comprising:
establishing a Long-Term Evolution (LTE) data connection between a cellular communication device and a first LTE base station using a LTE frequency band, wherein the LTE base station associated with a New Radio (NR) base station for dual connectivity;
establishing an NR data connection between the cellular communication device and the NR base station using a first NR frequency band, wherein the LTE data connection and the NR data connection are used concurrently for dual connectivity with the cellular communication device;
receiving a signal event notification indicating that an LTE signal strength measured by the cellular communication device and associated with a third frequency band has a signal strength that is greater than a threshold, the third frequency band being a next highest frequency band from the first NR frequency band;
in response to receiving the signal event notification, releasing the NR data connection; and
reestablishing the NR data connection using a second NR frequency band having a greater bandwidth than the first NR frequency band.
