Abstract: Apparatus and methods to support parallel access to services of multiple subscriber identity modules (SIMs) and/or electronic SIMs (eSIMs) by a wireless device are disclosed. The wireless device is a single-radio wireless device that includes wireless circuitry that supports an active voice or video connection via a single radio access network of a cellular wireless network at a time. To send or receive data for a second SIM/eSIM, when an active voice or video connection for a first SIM/eSIM uses the wireless circuitry, the single-radio wireless device can i) establish parallel, linked protocol data unit (PDU) sessions for different SIMs, ii) multiplex traffic for different SIMs over a common radio connection with SIM information embedded in protocol headers for routing by network equipment, and/or iii) use an additional dedicated bearer using a first, active SIM for each data network name (DNN) over which to route for a second, suspended SIM..

Abstract: Systems and methods provide steering of roaming (SoR) information during a user equipment (UE) mobility registration process. In other systems and methods, instead of triggering mobility and periodic registration, a UE performs initial registration until a valid SoR is received in a visited country or network as long as a subscriber identification module (SIM) or a universal SIM (USIM) of the UE indicates that the UE is expected to receive SoR information due to initial registration in a visited public land mobile network (VPLMN).

Abstract: There is provided a method for an access and mobility management function (AMF) in a wireless network, the method comprising: receiving, at the AMF, a registration request message from a user equipment (UE) the registration request message comprising a registration type parameter indicating a mobility registration update; in response to the registration request message, at the AMF, performing a mobility registration procedure for the UE in a visited public land mobile network (VPLMN) the registration procedure including receiving and storing UE context information at the AMF; determining that the UE context information includes a steering of roaming (SoR) indicator for mobility registration indicating that a unified data management (UDM) of a home public land mobile network (HPLMN) requests the VPLMN to retrieve SoR information in response to the registration type parameter indicating the mobility registration update when a SoR container has not been delivered to the UE in a previous registration; and in response to the SoR indicator for mobility registration, retrieving the SoR information from the UDM and delivering the SoR information to the UE in a registration accept message.

Abstract: There is provided a user equipment (UE) comprising: a memory devices to store a registration accept message; and one or more processors to: trigger a first initial registration procedure with a first visited public land mobile network (VPLMN); determine that the registration accept message from the first VPLMN does not include valid steering of roaming (SoR) information; release a connection with the first VPLMN; and instead of triggering a mobility registration or a periodic registration with a second VPLMN, attempt a second initial registration procedure with the second VPLMN.
