METHOD AND APPARATUS FOR PERFORMING VERTICAL HANDOVER IN SDR TERMINAL
First Claim
1. A vertical handover method which is performed by a Software Defined Radio (SDR) terminal capable of selectively executing at least one of a plurality of application services, the method comprising:
- receiving a handover request from an application service which is being currently executed;
selecting a new application service which is a handover target from among the 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.

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.

10. An apparatus for vertical handover which is included in a Software Defined Radio (SDR) terminal capable of selectively executing at least one of a plurality of application services, comprising:
-
at least one service execution unit which is software-reconfigurable and capable of executing various application services; and a handover execution unit to perform a handover between the application services that are executable by the SDR terminal; and a Software Communication Architecture (SCA) core framework, when receiving a handover request from the service execution unit which executes an application service, to generate a service execution unit for executing an application service that is a handover target, and to control execution of a handover of the SDR terminal in connection with the service execution unit and the handover execution unit. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
