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

Claim 0:
1. A method, comprising:
establishing a Long-Term Evolution (LTE) data connection between a cellular communication device and an LTE base station using a first LTE frequency band, wherein the LTE base station is 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 generated by the cellular communication device, wherein the signal event notification indicates that an LTE signal strength measured by the cellular communication device is greater than a threshold;
in response to receiving the signal event notification, releasing the NR data connection;
identifying a second NR frequency band that is (a) currently available for use by the cellular communication device and (b) has a greater bandwidth than the first NR frequency band; and
reestablishing the NR data connection using the second NR frequency band in response to the second NR frequency band having the greater bandwidth than the first NR frequency band.
