Method for supporting quality of service in heterogeneous networks
First Claim
1. A method for supporting a quality of service (QoS) service at a handed over network in heterogeneous networks, the method comprising:
- when there is a need of handover, requesting, at a serving network that is supporting the QoS service to a mobile terminal, the mobile terminal to offer demand QoS information;
sending, at the mobile terminal, a response message containing the demand QoS information of the mobile terminal to the serving network;
checking, at the serving network, whether or not each of candidate networks to which the mobile terminal is to be handed over can support the QoS service; and
determining, at the serving network, one of the candidate networks that can support the QoS service, and providing information on the determined candidate network to the mobile terminal such that the mobile terminal is handed over to the determined candidate network.

Abstract
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.
