Abstract
Wireless communication at a user equipment (UE) is described. In some cases, a UE may determine that a voice call is about to be setup or in the process of being setup with a cell that supports voice calls. While the voice call is pending, the UE may be motivated to connect to a cell that does not support voice calls. The UE may recognize that the cell does not support voice calls and refrain from connecting to the cell until after the voice call setup, and/or the voice call itself, has completed.
Claims64
A method for wireless communication at a user equipment (UE), comprising:
- determining, while the UE is in radio resource control (RRC) idle mode or in RRC connected mode with a first cell that supports voice calls, that the UE is to participate in a voice call setup operation;
- determining that the UE is to attempt to establish a connection to a second cell while the voice call setup operation is in progress, wherein voice calls are unsupported by the second cell;
- and
- preventing, by the UE, establishment of the connection to the second cell while the voice call setup operation is in progress based at least in part on voice calls being unsupported by the second cell.
A wireless communication user equipment (UE) apparatus, comprising:
- means for determining, while the apparatus is in radio resource control (RRC) idle mode or in RRC connected mode with a first cell that supports voice calls, that the apparatus is to participate in a voice call setup operation;
- means for determining that the apparatus is to attempt to establish a connection to a second cell while the voice call setup operation is in progress, wherein voice calls are unsupported by the second cell;
- and
- means for preventing, by the apparatus, establishment of the connection to the second cell while the voice call setup operation is in progress based at least in part on voice calls being unsupported by the second cell.
A wireless communication user equipment (UE) apparatus, comprising:
- a processor;
- memory in electronic communication with the processor;
- and
- one or more instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
- determine, while the apparatus is in radio resource control (RRC) idle mode or in RRC connected mode with a first cell that supports voice calls, that the apparatus is to participate in a voice call setup operation;
- determine that the apparatus is to attempt to establish a connection to a second cell while the voice call setup operation is in progress, wherein voice calls are unsupported by the second cell;
- and
- prevent, by the apparatus, establishment of the connection to the second cell while the voice call setup operation is in progress based at least in part on voice calls being unsupported by the second cell.
A non-transitory computer-readable medium storing code for wireless communication at a user equipment (UE), the code comprising one or more instructions executable to:
- determine, while the user equipment (UE) is in radio resource control (RRC) idle mode or in RRC connected mode with a first cell that supports voice calls, that the UE is to participate in a voice call setup operation;
- determine that the UE is to attempt to establish a connection to a second cell while the voice call setup operation is in progress, wherein voice calls are unsupported by the second cell;
- and
- prevent, by the UE, establishment of the connection to the second cell while the voice call setup operation is in progress based at least in part on voice calls being unsupported by the second cell.
