Abstract
Examples described herein relate to managing reselection for a wireless communication device having a first subscription associated with a first Radio Access Technology (RAT) and a second subscription associated with a second RAT, including determining an occurrence of a barring procedure that bars a target cell or a target frequency for the first subscription for a barring duration and deprioritizing the target cell or the target frequency for the barring duration on the second subscription
Claims30
A method for managing cell reselection for a wireless communication device having a first subscription associated with a first Subscriber Identity Module (SIM) and a second subscription associated with a second SIM, the method comprising:
- determining an occurrence of a barring procedure that bars a target cell or a target frequency for the first subscription;
- determining a mode associated with the second subscription;
- and
- deprioritizing the target cell or target frequency based on the mode.
A wireless communication device, comprising:
- at least one radio frequency (RF) resource;
- a processor configured to connect to a first Subscriber Identity Module (SIM) associated with a first subscription and to a second SIM associated with a second subscription, and configured to:
- determine an occurrence of a barring procedure that bars a target cell or a target frequency for the first subscription;
- determine a mode associated with the second subscription;
- and
- deprioritize the target cell or target frequency based on the mode;
- a memory.
A method for managing reselection for a wireless communication device having a first subscription associated with a first Radio Access Technology (RAT) and a second subscription associated with a second RAT, the method comprising:
- determining an occurrence of a barring procedure that bars a target cell or a target frequency for the first subscription for a barring duration;
- and
- deprioritizing the target cell or the target frequency for the barring duration on the second subscription.
A method for managing reselection for a wireless communication device having a first subscription associated with a first Radio Access Technology (RAT) and a second subscription associated with a second RAT, the method comprising:
- determining that a frequency or the first RAT is being deprioritized on the first subscription for a barring duration;
- determining whether a first Public Land Mobile Network (PLMN) associated with the first subscription is the same as a second PLMN associated with the second subscription;
- and
- deprioritizing, on the second subscription, the frequency or the second RAT in response to determining that the first PLMN and the second PLMN are the same.
