Apparatus for controlling multi-mode radio access and method for the same
First Claim
1. An apparatus for controlling multi-mode radio access comprising:
- a physical layer;
a radio system layer connecting with the physical layer for performing medium access control;
a radio adaptation layer, which connects with the radio system layer, at least comprising;
a configuration controller used to establish or control at least a radio link according to a signal packet so as to perform seamless handoff within different radio systems and set corresponding traffic control parameters; and
a traffic controller used to transmit a data packet according to the traffic control parameters and requirements of quality of service (QoS) of the data packet; and
a network layer for passing the data packet and signal packet to the radio adaptation layer, the network layer using an Internet protocol (IP) so as to make the apparatus able to roam within the different radio systems and support QoS mechanisms.

Abstract
A method and apparatus for controlling multi-mode radio access, more particularly, to a method and apparatus that supports multi-mode reconfigurable, quality of service (QoS) and seamless handoff in different radio systems so as to provide wire-line like QoS guarantee. The apparatus includes a network layer, a radio adaptation layer, a radio system layer and a physical layer. Therein, the radio adaptation layer is used to control the radio modules disposed in the radio system layer to support the QoS needed in the upper layer. The radio adaptation layer is also used to build up, correct and seamlessly change the radio link, and ensures that the packets from the upper layers can be orderly delivered to the lower layer with preset QoS.

17. A packet-transmitting method for controlling multi-mode radio access comprising:
-
recognizing a format of a received packet; determining if the received packet is a signaling packet; passing the received packet to a configuration controller if the received packet is the signaling packet, establishing a corresponding radio link according to parameters of the signaling packet and present network resources, and setting corresponding parameters of a traffic controller to fit predetermined requirements of QoS; and passing the received packet to the traffic controller if the received packet isn'"'"'t the signaling packet but a data packet, controlling a quality of a connection according to predetermined parameters of traffic control and then sending out the data packet orderly. - View Dependent Claims (18, 19, 20)

21. A seamless handoff method for controlling multi-mode radio access comprising:
-
determining if handoff is necessary according to a status of a present radio link, further comprising; reporting the status of the present radio link; determining if a quality of the present radio link degrades; obtaining an information of a radios system and determining if the handoff is necessary; and modifying a setting of a radio module to improve the quality of the present radio link if the handoff isn'"'"'t necessary; switching to a new radio link; releasing an old radio link; translating QoS attributes for mapping parameters; and setting parameters of a traffic controller to fit the new radio link. - View Dependent Claims (22, 23)

24. A radio link releasing method for controlling multi-mode radio access comprising:
-
issuing a message for releasing a radio link as an application program of an upper layer terminates a connection actively; passing the message for releasing the radio link to an end of a network; releasing the radio link by a radio module if a number of other connections existing in the radio link is zero and informing a call admission control that the radio link is released; and informing the call admission control that the connection is terminated if the number of other connections existing in the radio link is not zero. - View Dependent Claims (25, 26)
