POWER SCAN FOR ESTABLISHING CIRCUIT SWITCHED FALLBACK (CSFB) CALL |
摘要 |
In a method of wireless communication, a UE receives a redirection message from a first radio access technology (RAT) to move to a second RAT. The UE scans frequencies of the second RAT indicated in the received redirection message from the first RAT and does not detect a cell. The UE scans a third RAT and collects system information from a detected cell in the third RAT but does not camp on the detected cell in the third RAT. The UE scans frequencies of the second RAT indicated in the collected system information and detects a cell. The UE then performs a call setup with the detected cell of the second RAT. |

1. A method of wireless communication, comprising:
receiving a redirection message from a first radio access technology (RAT) to move to a second RAT; scanning frequencies of the second RAT indicated in the received redirection message from the first RAT but not detecting a cell; scanning a third RAT; collecting system information from a detected cell in the third RAT but not camping on the detected cell in the third RAT; scanning frequencies of the second RAT indicated in the collected system information, detecting a cell when scanning frequencies of the second RAT indicated in the collected system information; and performing a call setup with the detected cell of the second RAT. |
