One method includes performing, by a user equipment (UE) corresponding to multiple networks, sending a mobile terminated (MT) filter assistance information by: determining, by the UE, the MT filter assistance information; and sending, by the UE, the MT filter assistance information to a network. Another method includes receiving, by a UE including Multi-SIMs corresponding to multiple radio access networks (RANs), a paging message from a RAN of the multiple RANs, wherein the paging message comprises a first indication indicating a paging cause; and the paging message comprises a second indication indicating whether the paging cause is supported in the paging message. ## Claims ### Claim 1 A method for wireless communication, comprising: in response to a trigger condition, performing, by a user equipment (UE) corresponding to multiple networks comprising a first network and a second network, sending a mobile terminated (MT) filter assistance information by: determining, by the UE, the MT filter assistance information; and sending, by the UE, the MT filter assistance information to the first network, wherein: the UE indicates a MT filter revoke indication to the first network, and the MT filter assistance information that is stored in the first network is deleted upon receiving the MT filter revoke indication from the UE. ### Claim 2 (depends on 1) The method according to claim 1, wherein: the UE registers with the multiple networks by at least one of the following: registering the multiple networks with multiple subscriber identity modules (Multi-SIMs); or registering the multiple networks with a subscriber identity module (SIM). ### Claim 3 (depends on 1) The method according to claim 1, wherein: the multiple networks comprise at least one of the following: multiple radio access networks (RANs) comprising a first RAN and a second RAN; multiple core networks (CNs) comprising a first CN and a second CN; or a RAN and a CN. ### Claim 4 (depends on 1) The method according to claim 1, wherein: the MT filter assistance information comprises at least one of the following: an indication that the UE only is paged for a voice service comprising at least one of the following: a multimedia telephony (MMTel) voice service or circuit switched (CS) domain voice service for a evolved packet system (EPS); an indication that the UE is not be paged at all; a packet data network (PDN) connection for a MT notification and paging restriction; or a timer configuration for the MT filter assistance information, the timer configuration including a timer length. ### Claim 5 (depends on 1) The method according to claim 1, wherein: the trigger condition comprises that the UE detects a paging from the first network. ### Claim 6 (depends on 1) The method according to claim 1, wherein: the UE sends the MT filter revoke indication without entering into a connected state with the first network. ### Claim 7 (depends on 1) The method according to claim 1: further comprising: sending, by the UE, a resume request with the MT filter revoke indication to the first network, and receiving, by the UE, a RRCConnection release from the first network. ### Claim 8 (depends on 1) The method according to claim 1, wherein: the UE is at an inactive state with the first network; and the UE sends the MT filter revoke indication to the first network by a resume cause. ### Claim 9 (depends on 1) The method according to claim 1, further comprising: sending, by the UE, the MT filter revoke indication by entering into a connected state with the first network. ### Claim 10 (depends on 1) The method of claim 1: further comprising sending, by the UE, a message to indicate to revoke the MT filter assistance information to the first network; and receiving, by the UE, a RRCConnection release from the first network. ### Claim 11 (depends on 1) The method according to claim 1, wherein: the UE starts a timer when sending the MT filter assistance information; the UE deletes the MT filter assistance information upon the timer being expiry; and the UE resumes a paging detection. ### Claim 12 (depends on 1) The method according to the claim 1, wherein: the UE receive a timer configuration from an access stratum (AS) signalling or a non-access stratum (NAS) signalling; the NAS signalling comprises a register accept message; the AS signalling comprises at least one of the following: a system information (SI) or a dedicated AS signaling. ### Claim 13 (depends on 1) The method according to claim 1, wherein: in response to receiving the MT filter revoke indication form the UE, the first network sends the MT filter revoke indication to a RAN node. ### Claim 14 An apparatus comprising: a memory storing instructions; and a processor in communication with the memory, wherein, when the processor executes the instructions, the processor is configured to cause the apparatus to perform, corresponding to multiple networks comprising a first network and a second network, in response to a trigger condition, sending a mobile terminated (MT) filter assistance information by: determining the MT filter assistance information; and sending the MT filter assistance information to the first network, wherein: the apparatus indicates a MT filter revoke indication to the first network, and the MT filter assistance information that is stored in the first network is deleted upon receiving the MT filter revoke indication from the apparatus. ### Claim 15 A non-transitory computer-readable program medium storing instructions, wherein: the instructions, when executed by a processor in an apparatus, are configured to cause the processor to perform, corresponding to multiple networks comprising a first network and a second network, in response to a trigger condition, sending a mobile terminated (MT) filter assistance information by: determining the MT filter assistance information; and sending the MT filter assistance information to the first network, wherein: the apparatus indicates a MT filter revoke indication to the first network, and the MT filter assistance information that is stored in the first network is deleted upon receiving the MT filter revoke indication from the apparatus.
