Abstract
Systems, methods, and devices for wireless communication by a wireless communication device are described. A circuit switched fallback from an LTE cell to a GERAN cell is initiated. A system information type 3 message is received. The GERAN cell is accessed based on the system information type 3 message without receiving a system information type 13 message. A circuit switched connection is established on the GERAN cell. Other aspects, embodiments, and features are also claimed and described.
Claims30
A method for wireless communication by a wireless communication device, the method comprising:
- initiating a circuit switched fallback from an LTE cell to a GERAN cell;
- receiving a system information type 3 message;
- accessing the GERAN cell based on the system information type 3 message without receiving a system information type 13 message;
- and
- establishing a circuit switched connection on the GERAN cell.
An apparatus for wireless communication, comprising:
- a processor;
- a communications interface;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory, the instructions being executable by the processor to:
- initiate a circuit switched fallback from an LTE cell to a GERAN cell via the communications interface;
- receive a system information type 3 message via the communications interface;
- access the GERAN cell, via the communications interface, based on the system information type 3 message without receiving a system information type 13 message;
- and
- establish a circuit switched connection on the GERAN cell via the communications interface.
A computer-program product for wireless communications, the computer-program product comprising a non-transitory computer-readable medium having instructions thereon, the instructions comprising:
- code for causing a wireless communication device to initiate a circuit switched fallback from an LTE cell to a GERAN cell;
- code for causing the wireless communication device to receive a system information type 3 message;
- code for causing the wireless communication device to access the GERAN cell based on the system information type 3 message without receiving a system information type 13 message;
- and
- code for causing the wireless communication device to establish a circuit switched connection on the GERAN cell.
