TECHNIQUES AND APPARATUSES FOR QUICK RELEASE OF RADIO RESOURCE CONTROL CONNECTION AFTER SESSION TERMINATION

WIPO Patent Application WO/2019/061251

A1

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an extended service request (ESR) message to a base station based at least in part on determining that a session of the UE has been terminated, wherein the session uses a first radio access technology (RAT). The UE may receive a redirection message instructing the UE to switch to a second RAT based at least in part on transmitting the ESR message. The UE may remain camped on the first RAT despite receiving the redirection message. The UE may transmit a tracking area update (TAU) message to the base station while remaining camped on the first RAT, wherein the TAU message includes an indication that the UE does not require a bearer. Numerous other aspects are provided.
