<p>A method for ensuring continuity of Quality of Service in a Resource and Admission Control System, the method includes the steps of that: when a terminal user moves from a transport layer entity to another transport layer entity, after the current transport layer entity has completed the link layer mobility switching (403) operation, the link layer mobility event of the terminal user is notified to the Resource and Admission Control System to which the terminal user belongs. The Resource and Admission Control System judges whether the terminal user moves in a control range of the same Resource and Admission Control System, if it is yes, the reserved resource of the terminal user is searched in a database itself, and the resource is reserved on the current transport layer entity according to the resource reserved. Using the invention, in the next generation network, when the terminal user moves among different transport layer entities under the control of the same Resource and Admission Control System, the continuity of Quality of Service should be ensured.</p> |
