Publication number: 20090109930Abstract: A method is related to support a QoS service at a handed over network in heterogeneous networks. A serving network requests the mobile terminal to offer demand QoS information, when there is a need of handover. The mobile terminal sends a response message containing the demand QoS information to the serving network, and each candidate network maps the demand QoS information to its network resources to judge whether or not to support the QoS service. And the serving network determines one of the candidate networks that can support the QoS service depending on the judgment of the candidate networks, and provides information on the determined candidate network to the mobile terminal such that the mobile terminal is handed over to the determined candidate network.Type: ApplicationFiled: October 29, 2008Publication date: April 30, 2009Applicant: POSTECH ACADEMY-INDUSTRY FOUNDATIONInventors: Young Joo Suh, Deok Jin Kim, Wan Seon Lim, Joo Young Baek
