Patent ID: 11863594
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. An electronic device, comprising,
a memory;
at least one antenna module comprising at least one antenna; and
at least one communication processor configured to communicate with a first communication network, a second communication network, and an IP multimedia subsystem (IMS) network, through the at least one antenna module,
wherein the at least one communication processor is configured to:
in receiving a first call request, control the electronic device to perform a call by voice communication connection through the second communication network,
based on identifying that the call is disconnected, start a first timer associated with returning to the second communication network from the first communication network and store information for a cell of the second communication network, as first cell information, in the memory, and
connect to the first communication network,
based on identifying that a second call request is received before the first timer expires, control the electronic device to perform connection with the second communication network based on the first cell information stored in the memory, and
based on identifying that a triggering signal of an application corresponding to the first communication network is received before the timer expires, control the electronic device to initialize the first timer and the stored first cell information and maintain the connection to the first communication network.
