An electronic device including a communication circuitry, a processor, and a memory is provided. The processor of the electronic device receives a user equipment (UE) capability enquiry that includes information indicating the number of carrier aggregation (CA) combinations associated with a network from the network using the communication circuitry and determines UE capability information based on at least one of the number of default CA combinations of the electronic device, the number of CA combinations of a region associated with the network, the number of CA combinations of a country associated with the network, the number of CA combinations corresponding to a supported frequency band of a mobile network operator (MNO) associated with the network, and the number of CA combinations associated with the network.

Method for transmitting carrier combination for carrier aggregation and electronic device therefor

A method of providing call services for an electronic device is provided. The method may include receiving a call request from the user; determining whether the call request is a request for a call via an Internet Protocol (IP) Multimedia System (IMS) network; making, when it is determined that the call request is a request for a call via an IMS network, an attempt to set up the call via the IMS network; determining whether the attempt for the call setup via the IMS network is successful; and performing Circuit Switched Fallback (CSFB) when it is determined that the attempt for the call setup via the IMS network is unsuccessful.
