Abstract: A method for optimizing PWS message reception in multi-SIM multi-standby UE and UE thereof are disclosed. In an embodiment, the method includes receiving a scheduling information of SIBs containing a PWS message from a first network entity and the scheduling information of SIBs containing the PWS message from second network entity.

The method checks whether the PWS message identifier is present in a secondary CBS configuration list of the second SIM, and terminates reception of the SIBs by the second SIM when the PWS message identifier is absent. A CBS notification is sent by the first SIM, containing the PWS message to a CBS controller in the absence of error while receiving the PWS message from the SIBs.
