A mobile network hotspot sharing method includes starting hotspot sharing, receiving, from a hotspot access device for a shared hotspot and after starting the hotspot sharing, a connection request, performing authentication on the connection request, and after the authentication on the connection request succeeds, allowing the hotspot access device to access the shared hotspot. Then, the hotspot sharing device receives data from the hotspot access device, and sends the data using an uplink network interface card of the shared hotspot, where the uplink network interface card includes a subscriber identity module (SIM) card that has activated mobile network data and that is in the hotspot sharing device, and the SIM card includes a non-default data service card.

Methods, systems, and devices for wireless communications are described that support subscriber identification module (SIM) prioritization based on service priority and quality of service (QoS) parameters. A user equipment (UE) may identify a set of available RF components for communications at the UE that may be shared between a first SIM and a second SIM. The UE may identify multiple resource partitions of the set of available RF components, each resource partition providing resources for contemporaneous communications of both the first SIM and the second SIM. The UE may select one of the resource partitions for the contemporaneous communications based on service level priorities associated with each SIM and which resource partition provides sufficient RF resources to satisfy the QoS parameters associated a highest service level priority of the multiple SIMS.

Methods, systems, and devices for wireless communications are described. An example method may include identifying that a user equipment (UE) includes a first subscriber identification module (SIM) card in a first card slot of a plurality of card slots of the UE is associated with a first operator and associated with a first subscription for which use of the UE is subject to a contractual obligation to the first operator. The method may further include determining that the UE is in communication with a first radio access network of the first operator and communicating in accordance with a second subscription associated with a second SIM card in a second card slot, the communicating allowed based at least in part on the first SIM card associated with the first operator being in the first card slot and the UE being in communication with the first radio access network.

In accordance with an embodiment, an electronic device includes a secure element configured to implement a plurality of operating systems; and a near field communication module coupled to the secure element by a single bus and by a routing circuit configured to route routing data between the plurality of operating systems and a receive circuit of the near field communication module.

The present invention provides a method for a user equipment, UE, device to hand over a connection to a first data network from a first access network of a first mobile communications network to a second access network of a second mobile communications network, in which a communication tunnel is established in the first communications network to a non-3GPP interworking function and after the handover to the second mobile communications network, the second network establishes a connection to that N3IWF.

Resource scheduling method, communications device, network device and storage medium are disclosed. The method is applied to a communications device including UE1 and UE2. The method includes: sending a time-division multiplexing pattern request to a network side device, where the network side device includes a first network side device and/or a second network side device; receiving response information of a time-division multiplexing pattern sent by the network side device according to the time-division multiplexing pattern request, where the response information of a time-division multiplexing pattern includes configuration information of a time-division multiplexing pattern and/or confirmation information of a time-division multiplexing pattern; and determining, according to the response information of a time-division multiplexing pattern, a first transmission time window for the UE1 and a second transmission time window for the UE2, where the first transmission time window and the second transmission time window do not overlap.

An improved core network that allows a UE to still initiate and/or receive communications via a native SIM line even if the registration of a virtual line fails is described herein. For example, the UE may include embedded virtual line settings that, when enabled, cause the UE to transmit a virtual line registration request to the core network. The core network can determine whether the UE is authorized to register a virtual line. If the UE is authorized, the core network can register a native SIM line, register the virtual line, and transmit a single message to the UE indicating that the native SIM and virtual lines are registered. If the UE is not authorized, the core network still registers the native SIM line and transmits a single message to the UE indicating that the native SIM line is registered.

A method of wireless communication performed by a user equipment (UE) includes: operating in a Dual SIM Dual Standby (DSDS) mode in which a first subscriber identity module (SIM) is designated as a default data subscription (DDS); transmitting a sounding reference signal (SRS) from a communication port of the UE, wherein the SRS has a timing offset assigned by a network associated with the first SIM; receiving paging messages from a network associated with a second SIM; determining an offset adjustment to avoid a collision between the SRS and the paging messages; sending a request to the network associated with the first SIM to adjust the timing offset according to the offset adjustment; and receiving an offset change configuration from the network associated with the first SIM.
