The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The disclosure discloses a terminal including a transmission and reception unit and at least one processor. The at least one processor controls the transmission and reception unit so that the transmission and reception unit receives a message such as an SMS, an MMS, or an OTT including event download information from a communication operator server, searches for event download information from the received message such as the SMS, the MMS, or the OTT, transmits the event download information to another terminal if necessary, and receives an event from a profile server with reference to the event download information.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect that a first subscription, of a plurality of subscriptions associated with the UE, is associated with an active service on a first cellular network. The UE may search, for a second subscription of the plurality of subscriptions, for radio access technologies (RATs) and frequency bands that are compatible with a dual active mode of the UE. In some aspects, the UE may detect that the active service on the first cellular network has ended. Accordingly, the UE may search, for the second subscription, for RATs and frequency bands that are compatible with the dual active mode of the UE and for RATs and frequency bands that are incompatible with the dual active mode, before expiry of a timer associated with a power saving state. Numerous other aspects are described.

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE).

Embodiments herein disclose a method performed by a terminal in a mobile communication system. The method includes performing a registration procedure on a first standalone non-public network (SNPN), selecting a second SNPN based on a predetermined condition, and transmitting, to a network entity, a registration request message on the second SNPN for an initial registration, in case that the second SNPN differs from the first SNPN.

A method performed by, and a system embedded within, a communication device operating in a communication network, performing the steps of: obtaining a plurality of caller identification codes for the caller device, where each of the caller identification codes identifies the caller device in a network; obtaining at least one rule for selecting a caller identification code from the plurality of caller identification codes according to a characteristic of the called device; obtaining a characteristic of the called device; selecting a caller identification code from the plurality of caller identification codes according to the characteristic of the destination telephone identification, or caller environment or destination environment parameters, or caller decision on the time of making the call; and forwarding the selected caller identification code to any of another communication network and a terminal device of a communication network.

Various embodiments disclosed that describe systems to facilitate paging an idle subscriber identity module using a connected subscriber identity module operating in a single radio configuration. According to some embodiments, a system can comprise receiving a paging request that is designated for a first device of a communication device, wherein the communication device comprises the first device and a second device; determining whether the second device is in an active state; and in response to the determining that the second device is in the active state, transmitting a message to second device indicating that the paging message was received for the first device.

A terminal registration processing method and device are provided. The method includes: detecting that an identity card is inserted into at least one card slot; reading an identifier of the identity card; acquiring, from a database, a network identity corresponding to the identifier, wherein the database stores a correspondence between a network identity and an identifier of a registered card; and registering the identity card according to a result of acquiring the network identity.

Methods are disclosed for provisioning and/or controlling operator profiles in terminals, each having an integrated circuit card identified by an integrated circuit card identifier. According to one aspect, a discovery server is configured with an authorization table including associations of integrated circuit card identifier, service provider identifier, and operator identifier(s). The discovery server receives, from a data preparation node, an event registration request that includes a number of elements. The discovery server determines whether the event is authorized. If so, the event is registered. This enables a terminal to seek to retrieve the event, to contact the data preparation node, and to eventually perform the profile operation. Some embodiments enable the network-initiated provisioning and/or controlling of operator profiles in machine-to-machine devices.

A data volume exchange server includes a terminal IF unit configured to receive an exchange request for a contract data volume of an own country and a contract data volume of another country from terminals of subscribers having contract data volumes of telecommunication carriers of countries different from each other, a data volume exchange unit configured to perform matching of a pair in which another country that requests a contract data volume in one of the received exchange requests matches the own country that provides a contract data volume in another of the received exchange requests, and a server IF unit configured to instruct the communication servers of the telecommunication carriers in the countries to transfer a contract data volume of a matched subscriber of the own country as an exchanged data volume of a subscriber of the other country who is a matching partner.

This application provides a frequency band control method in an abnormal scenario of a dual-card terminal and a terminal device, and relates to the field of communications technologies. In solutions of this application, for a dual-card user scenario that supports a 5G SA mode or a 5G NSA mode, it is determined whether a frequency band combination of two cards is in a blacklist and whether signal quality of a primary card and/or signal quality of a secondary card meet/meets a preset threshold. If the frequency band combination of the two cards is in the blacklist and the signal quality of the primary card and/or the signal quality of the secondary card are/is less than the preset threshold, an NR capability of a terminal device is controlled to fall back, for example, an SA capability is disabled, or an NR link in an ENDC link is released, to improve the signal quality of the two cards. Further, when the frequency band combination of the two cards changes and a changed frequency band combination of the two cards is not in the blacklist, the NR capability of the terminal device may be controlled to be restored. In the solutions of this application, a case in which signal quality deteriorates because the dual-card terminal device works on a problem frequency band combination can be alleviated.
