A data transmission method and device, where the method includes determining, by a first station device, that a second station device supports a first service, receiving a device group join request message that is sent by the second station device according to a media access control (MAC) address of a first device group, where the first device group is a device group of the first service and is a device group to which the first station device belongs, sending a device group join response message to another station device in the first device group and the second station device according to the multicast MAC address of the first device group in a contention transmission manner, and performing data transmission of the first service with the second station device in a service window of the first service, where the service window includes a time and/or a channel of service transmission.

A subscriber issues a message to a resource host to request subscription to multiple resources. This message may indicate identifiers of these resources, event notification criteria for each individual resource and define cross-resource notification criteria such as time window type and time window size. The resource host issues cross-resource notifications to the subscriber or its designated notification targets when expected changes on the target resources occur within a time window.

The present disclosure provides a method of controlling a display of a SIM card function menu, the method including: determining whether a preset command corresponding to a corresponding preset function is received from the SIM card; and uninstalling a default function module corresponding to the preset function, in response to no preset command corresponding to the preset function being received from the SIM card. The present disclosure further provides a device having a storage function and a terminal.

A communication device may be configured to access a plurality of subscriptions for a plurality of providers. For example, a communication device may be configured with at least one subscriber identity module (SIM). For a communication device having a plurality of subscriptions accessible thereto, the selection of a subscription to connect to a destination network may be configurable. The selection of a subscription from a plurality of available subscriptions may be based on a cost (e.g., financial cost, data cost, or another resource) associated with connecting to a destination network using different subscriptions. For example, a first subscription may be selected if connection to the destination network is more expensive using a second subscription and/or if the balance on the second subscription is too low.

The present invention discloses methods and systems for selecting at least one SIM card for data communication at a wireless communication device which is capable of housing a plurality of SIM cards. When a switching condition is satisfied, the wireless communication device selects a second SIM card group, and disconnects one or more connections established using any non-second group SIM card. Non-second group SIM cards are SIM cards that are not in the second SIM card group. A selected SIM card from the second SIM card group is then used for data communications. The steps are repeated until (i) the switching condition is no longer satisfied, (ii) no more SIM cards selected from the second SIM card group can be used for data communications or (iii) no more connection is made using non-second group SIM cards

A method is provided in one example embodiment and may include configuring a slice identity for each of a plurality of virtual radio access network (vRAN) slices, wherein each vRAN slice comprises functionality to perform, at least in part, one or more radio protocol operations on subscriber traffic; configuring an allotment of radio resources that can be utilized by each vRAN slice of the plurality of vRAN slices; receiving, by a slice manager, a subscriber profile identity (SPID) for a subscriber; and mapping the SPID for the subscriber to a particular vRAN slice of the plurality of vRAN slices. The method can further include communicating the mapping for the subscriber to the particular vRAN slice to which the SPID is mapped. The method can further include communicating the allotment of radio resources that can be utilized by the particular vRAN slice to the particular vRAN slice.

The present disclosure relates to a communication technique that combines a 5G communication system for supporting a data rate that is higher than that of a beyond 4G system with IoT technology, and a system thereof. The present disclosure may be applied to intelligent services on the basis of 5G communication technology and IoT related technology, such as smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security and safety related services. Disclosed is a method for causing a cellular network itself to receive provisioning of a SIM profile to make it possible to use a normal cellular network service.

A network function and a method for associating a UE of a UE group to a PDU session with in a CN. The NF establishes a shared PDU session for the UE group before all of the UEs in the UE group register with the CN and binds a UE that has not yet registered with the CN to the shared PDU session when the UE registers with the CN, provided the UE will share at least one of a UL UP connection and a DL UP connection associated with the shared PDU session. The NF may be an SMF.
