When a service is released in a portable terminal that supports different communication modes due to a network problem, the call connection method and apparatus reconnects the service to another network. The call connection method includes performing a first service through a first network, analyzing, when the connected first service is released, the cause of disconnection, acquiring, when the cause of disconnection is a problem in the first network, connection information, and attempting to connect a second service through a second network based on the connection information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Service connection apparatus and method in portable terminal","description":"A call connection method and apparatus are disclosed.
