According to various embodiments, an operating method of an electronic device may provided, and the operating method may comprise determining initiation of a voice call on a first Subscriber Identity Module (SIM), while availing first data services through the first SIM, wherein the initiation of a voice call leads to a fallback from a first Radio Access Technology (RAT), wherein a Default Data Subscription/Service (DDS) is set to the first SIM, registering with a first network through a second SIM, in response to determining the second SIM is registered with a second network with a second RAT, and availing the first data services from the second SIM that is registered with the first network, while engaging in the voice call on the first SIM. Other various embodiments may be possible.

A system includes a subscription storage that stores an APN for identifying a home base station and the service class available for a UE as subscription information, in correspondence with a mobile terminal identifier for identifying UE; a positional information update request receiver for receiving a positional information update request of UE 70 from an MME; and a positional information response transmitter that extracts the available service class included in the positional information update request, from the subscription storage and transmits a positional information update response included with the extracted service class to MME. With this configuration, it is possible to provide a mobile communication system in which, for a plurality of services of a home base station, the owner of a home base station can set the access right for each of the services, and communication data is transferred based on the set access right.

Embodiments include systems and methods for enabling multicast service data transport for mobility between multicast/broadcast service (MBS) supporting and non-MBS supporting access nodes. Various aspects include methods for supporting an MBS session. In some embodiments, an MBS session context may indicate at least one multicast flow identifier (ID) for an MBS session and a unicast Quality of Service (QoS) flow ID for a unicast Packet Data Unit (PDU) session, wherein the MBS session context associates the unicast QoS flow ID with the at least one multicast flow ID.
