Abstract
Disclosed are a method and apparatus for allowing a Software Defined Radio (SDR) terminal to perform a vertical handover between different services. The vertical handover method includes: receiving a handover request from an application service which is currently being executed; selecting a new application service which is a handover target from among a plurality of application services, in response to the handover request; installing the new application service in the SDR terminal so that the new application service is executable by the SDR terminal; and performing a handover to the new application service. Accordingly, since handover is performed seamlessly between different services, continuity of service may be ensured.
