This application provides a method for returning from a low-standard network to a high-standard network, to resolve a problem that a primary card of a terminal device in dual SIM dual standby single pass mode cannot return to the high-standard network after falling back from the high-standard network to the low-standard network during a data service. The method includes: detecting that a first subscriber identification module SIM card of the terminal device falls back from a first-standard network to a second-standard network; obtaining a registration status of a second SIM card, where the registration status includes an operator of the second SIM card and a network on which the second SIM card camps, and the first SIM card and the second SIM card enable the terminal device to work in the dual SIM dual standby single pass mode; obtaining a target standard network based on the registration status of the second SIM card; and registering the first SIM card with the target standard network.

A transaction management platform may partition an amount associated with a group service plan into a plurality of portions. The transaction management platform may provide a graphical user interface to a primary user device of the plurality of user devices. The transaction management platform may receive, from the primary user device, a request for a transaction associated with a portion of the plurality of portions. The portion may be attributable to a secondary user device of the plurality of user devices. The transaction management platform may provide to the secondary user device of the plurality of user devices a unique link that has been generated based on one or more parameters and that enables the secondary user device to complete the transaction. Based on the secondary user device completing the transaction, the transaction management platform may process the transaction to provide an updated amount.

Accordingly, embodiments herein disclose a method for handling a closed access group (CAG) related procedure in a wireless communication system. A network may receive a radio resource control (RRC) resume request message from a user equipment (UE). The network may determine whether the at least one CAG identifier (ID) broadcasted in a CAG cell is included in an allowed CAG list of the UE (100) in response to the RRC resume request message. The network may proceed with a RRC resume procedure in response to determining that the at least one CAG ID is included in the allowed CAG list.

The present disclosure relates to a communication method, system, base station, and terminal. The method includes: sending, by a first BS, a broadcast message, which comprises: a NID and a PLMN ID, which correspond to each of one or more SNPNs supported by the first BS; receiving, by the first BS, a connection request sent from a terminal, wherein the connection request represents that the first BS supports at least one of one or more SNPNs subscribed by the terminal; establishing, by the first BS, a RRC connection with the terminal; receiving, by the first BS, a RRC connection setup complete message sent from the terminal, wherein the RRC connection setup complete message carries a NID and a PLMN ID, which correspond to a SNPN that the terminal selects to access; and connecting, by the first BS, the terminal to the SNPN that the terminal selects to access.

A method comprising obtaining, from a master user, a device usage allocation applicable to two or more devices, the two or more devices being associated with another user, the another user being different from the master user, obtaining an aggregate measure of device usage associated with the two or more devices, if the aggregate measure of device usage associated with the two or more devices satisfies a condition relative to the device usage allocation, managing an activity of the two or more devices, and sending a notification to at least one of the two or more devices, the notification for presentation to the another user through a user interface of the at least one of the two or more devices.

Providing multi-device services using a network application programming interface. The server obtains the accessibility in-ormation which indicates the plurality of devices and their capabilities. The plurality of devices have a same user identity. In this way, the server can take control on devices of participate for MuD services.

A service registration method, a terminal, and a network side device are provided. The terminal includes a first subscriber identity card module associated with a first subscriber identity card and a second subscriber identity card module associated with a second subscriber identity card. The method includes: accessing a first mobile network based on the first subscriber identity card; and transmitting a voice over wireless fidelity (VoWiFi) registration message of the second subscriber identity card based on the first mobile network.

To enable a private enterprise to subscribe to wireless service provided at a site of the private enterprise using a private radio access network (RAN), one embodiment is directed to a hyperscale network configured to: obtain subscription information for providing the wireless; determine initial configurations for physical entities deployed at the site; store the determined initial configurations in vendors clouds; deploy, in the hyperscale network, virtual entities needed to provide the wireless service; instruct the private enterprise to cause the physical entities deployed at the site to perform initial bootstrap processes whereby the physical entities download the determined initial configurations for use thereby in communicating with at least one of the virtual entities; and provide final configurations to the physical entities and the virtual entities for use thereby in configuring the physical entities and the virtual entities to provide the wireless service at the site using the RAN.

Embodiments of the present disclosure provide a method, an apparatus, and a system for changing an association relationship between an MCPTT user and an MCPTT group. A method for changing an association relationship between an MCPTT user and an MCPTT group is performed by a first network element device, including: receiving an association change request sent by first UE, where the association change request includes request information, the request information is used to indicate that a first MCPTT user requests to change an association relationship between a second MCPTT user and a first MCPTT group, and the first MCPTT user is an MCPTT user using the first UE; and setting the association relationship between the second MCPTT user and the first MCPTT group according to the association change request.
