Abstract: This disclosure describes a communication system associated with a radio access technology (RAT). The communication system includes an Internet protocol (IP) multimedia subsystem (IMS) server, and one or more processors configured to perform operations. The operations include receiving, from a user equipment device (UE) camped on the RAT, a request for IMS Packet Data Unit (PDU) establishment or IMS session initiation protocol (SIP) registration; sending to the UE a rejection message associated with the SIP registration or the IMS PDU establishment; receiving, from the UE, an IMS failure message that comprises an IMS failure cause; determining, based on the IMS failure message, whether the IMS failure cause is temporary or permanent; and responsive to determining that the IMS failure is temporary, temporarily disabling the RAT for the UE.

Abstract: Apparatuses and computer-readable storage media for handling timers for mobile terminated circuit-switched fallback (MT CSFB) calls. An apparatus for a user equipment (UE) includes processing circuitry operably coupled to a data storage device. The data storage device is configured to store a value of an extended service request for mobile terminated services (EXT-MT) timer. The value of the EXT-MT timer is less than a value of a guard timer of a Visitor Location Register (VLR). The processing circuitry is configured to start the EXT-MT timer and generate an extended service request message to be transmitted to a Mobility Management Entity (MME) responsive to a paging for an MT CSFB call, and attempt to select a radio access technology of a different type of network if the EXT-MT timer expires before the UE successfully performs inter system change and a circuit switched fallback cancellation request was not received from a subscriber.

Abstract: This disclosure describes a user equipment device (UE). The UE includes one or more antennas; one or more radios, where each of the radios is configured to perform cellular communication using a plurality of radio access technologies (RATs) that support voice over an Internet protocol (IP) multimedia subsystem (IMS); one or more processors coupled to the one or more radios, where the one or more processors are configured to cause the UE to perform operations including: sending, via a first RAT, a first request for IMS registration to an IMS server; receiving, from the IMS server, an IMS rejection message indicating failure of the IMS registration; determining, based on the IMS rejection message, that the IMS registration failure is temporary; responsively re-attempting IMS registration with the IMS server; and determining to camp on the first RAT in response to receiving an IMS acceptance message from the IMS server.

Abstract: A wireless device may transmit, using a first SIM associated with a first radio, a first attach request to a network node and transmit, using a second SIM associated with a second radio, a second attach request to the network node. Additionally, the wireless device may receive, operating in a multiple-subscriber identity module (MSIM) mode, an attach reject message including an attach reject cause code from the network node. The wireless device may transition, based at least in part on reception of the attach reject message, the second SIM to a limited service camped state, disable one of the first radio or second radio, transition to a single-SIM mode, and communicate with the network node via the first SIM.

Abstract: This disclosure relates to a user equipment (UE) circuitry comprising a processor, wherein the processor is configured to: receive a message indicating a redirection from a first radio network to a second radio network while the UE is registered in the first radio network under a first location area code (LAC); initiate a cell search for radio cells of the second radio network, wherein a specific LAC is assigned to at least one radio cell of the second radio network; and connect to a first radio cell found by the cell search based on a comparison of a LAC of the first radio cell and the first LAC under which the UE is registered in the first radio network.
