Assigning a UE to a carrier based on the UE ping-ponging between base stations

A method for controlling a UE situated in both a coverage area of a first base station and a coverage area of a second base station involves detecting that the UE is ping-ponging between being served by the first base station and being served by the second base station and determining that the second base station is a relay base station. Further, the method involves, responsive to detecting the ping-ponging and determining that the second base station is a relay base station, (a) determining a carrier on which the first base station provides service and on which the second base station does not provide service, and (b) based on the first base station providing service on the determined carrier and the second base station not providing service on the determined carrier, causing the UE to be served by the first base station on the determined carrier.

Embodiments of this application provide an information processing method and an apparatus. When a terminal device accesses or camps on a first cell served by a second network device, the terminal device records and stores first information of the terminal device in the first cell, where the first information may include connection failure report information of a radio link failure (RLF) or a handover failure, and/or measurement information obtained by performing measurement by using a minimization of drive tests (MDT) technology. After accessing a second cell, the terminal device may send, through the second cell, the first information to a first network device to which the second cell belongs, and a RAT corresponding to the second cell is different from a RAT corresponding to the first cell.

Employing signal to interference-noise ratio in determining initiation of a user equipment handover event in a 5G or other next generation network

Determining to initiate a user equipment handover event based on a signal-to-interference-plus-noise ratio value is disclosed. The disclosed subject matter can employ the signal-to-interference-plus-noise ratio value in lieu of a reference signal receive power value. In an aspect, a handover based on the signal-to-interference-plus-noise ratio value can generally be determined faster and with greater reliability than basing the handover on the reference signal receive power value. In an aspect, some embodiments can substitute a determined uplink signal-to-interference-plus-noise ratio value for a downlink signal-to-interference-plus-noise ratio value. In some embodiments, a predicted signal-to-interference-plus-noise ratio value can be determined based on historical channel characteristics, hysterical wireless network environment features, or other historical data. A predicted signal-to-interference-plus-noise ratio value can be validated to a determined current signal-to-interference-plus-noise ratio value, permitting a validated predicted value to be employed until a next validation event.
