Home or higher priority PLMN scan in 4G connected mode

摘要

Methods and systems facilitating a preferred network scan in a 4G communications system are disclosed. A user device identifies a new search event when operating in connected state. The user device transitions to idle state, performs a preferred network scan, and returns to connected state.

主权项

1. A computer-implemented method for a user device, comprising:
identifying a new search event for the user device operating in a connected state in a fourth generation (4G) communications system; determining whether the user device is in a discontinuous reception (DRX) mode; responsive to determining that the user device is in the DRX mode, identifying a first DRX wakeup interval of the user device; responsive to determining that the first DRX wakeup interval of the user device does not exceed a first threshold associated with a first frequency to be scanned during a first portion of a preferred network scan, requesting a second DRX wakeup interval greater than the first threshold from a server; performing the first portion of the preferred network scan on the first frequency during an instance of the second DRX wakeup interval; responsive to determining that the second DRX wakeup interval exceeds a second threshold associated with a second frequency to be scanned during a second portion of the preferred network scan, reconfiguring the user device back to the first DRX wakeup interval; and performing the second portion of the preferred network scan on the second frequency during an instance of the first DRX wakeup interval.
