METHOD FOR VERIFICATIONS AND FAST QOS ESTABLISHMENT
First Claim
1. A wireless communication system comprising a first communication network and a second communication network different from each other;
- and a mobile wireless user terminal that communicates with the networks;
the system comprising;
the first communication network that evaluates a network resource used by the mobile wireless user terminal, and generates and transmits a QoS history information unit indicating the evaluation result to the mobile wireless user terminal;
the mobile wireless user terminal that requests for resource establishment to the second communication network when switching the communicating party from the first communication network to the second communication network and transmits the QoS history information unit to the mobile wireless user terminal; and
the second communication network that, when receiving the request for resource establishment from the mobile wireless user terminal, allocates the network resource to the mobile wireless user terminal based on the QoS history information.

Abstract
A wireless communication system is provided for rapidly establishing the QoS resource on different communication networks. In this system, the NAP (104) evaluates a network resource used by the MT (106), and generates the QoS history information unit indicating the evaluation result. The AAA (140) authenticates the QoS history information unit generated by the NAP (104). The NAP (104) transmits the authenticated QoS history information unit to the MT (106). The MT (106) request for a resource establishment to the NAP (304) when switching the communicating party from the NAP (104) to the NAP (304), and transmits the QoS history information unit. The NAP (304) verifies the authenticity of the QoS history information unit to the AAA (140) when receiving the request for resource establishment from the MT (106) and allocates the network resource to the MT (106) based on the QoS history information unit.

6. A method of establishing a resource when a mobile wireless user terminal switches the communicating party from a first communication network to a second communication network, the method comprising:
-
a first step in which the first communication network evaluates a resource utilization of the mobile wireless user terminal; a second step in which the first communication network generates and transmits a QoS history information unit indicating the evaluation result to the mobile wireless user terminal; a third step in which the mobile wireless user terminal requests for a resource establishment to the second communication network and transmits the QoS history information unit; and a fourth step in which the second communication network allocates the network resource to the mobile wireless user terminal based on the QoS history information unit. - View Dependent Claims (7, 8, 9, 10)
