Abstract:
1. A wireless communication system comprising: a plurality of wireless access networks each including a base station and a packet control apparatus; a plurality of node apparatuses each connecting one of said wireless access networks to an IP network; and an authentication server storing communication quality level information assured previously by contract for each of a plurality of wireless mobile stations, each of said wireless access networks assuring a communication quality of packet flow between the node apparatus connected to said packet control apparatus and a particular wireless mobile station according to a first communication quality request from the particular wireless mobile station in communication with said base station, wherein at least one of said base station and said packet control apparatus in each of said wireless access networks includes: means for converting a second communication quality request into a third communication quality request acceptable to communication resources of the wireless access network, wherein the second communication quality request is selected from a plurality of stored parameter entries of the first communication quality request received from the particular wireless mobile station with reference to the communication quality level information acquired from said authentication server and included in a communication quality parameter group in a range assured to the particular wireless mobile station, means for controlling the communication quality of packet flow for the wireless mobile station according to the third communication quality request; and means for notifying the node apparatus connected to the packet control apparatus of the second communication quality request, wherein each of said node apparatuses includes: means for storing second communication quality requests notified from said wireless access network, means for notifying, when a wireless mobile station in communication with said node apparatus moves to another wireless access network corresponding to another node apparatus, said another node apparatus, which is a handover target, of the second communication quality request corresponding to the wireless mobile station; and means for notifying, when receiving the second communication quality request of the wireless mobile station from said another node apparatus, the wireless access network, connected to the node apparatus, of the received second communication quality request, wherein, when a wireless mobile station having moved into the another wireless access network, at least one of the base station and the packet control apparatus of each of said wireless access network converts, when receiving the second communication quality request from the node apparatus, the received second communication quality request into a fourth communication quality request acceptable to communication resources of the another wireless access network, and controls the communication quality of packet flow for a wireless mobile station having moved into the another wireless access network according to the fourth communication quality request.
