A wireless access router for separately controlling a traffic signal and a control signal is provided. In a mobile communication access network structure, in order to optimally support a mobile communication terminal, a control signal and a traffic signal of a base station are divided, and a router is controlled by mobile communication system functions such as a mobility management function, a QoS management function, a session control of the terminal, a mobility control, and a QoS control function that are effectively processed. With a wireless access router having the divided control signal and traffic signal, it is expected the traffic concentration and a packet transmission delay can be prevented.

The wireless access router of claim 1, wherein the access manager further comprises an access controller to perform wireless link establishment/disconnection, or radio resource reservation, or QoS reservation, or session and terminal mobility management functions, or any combination thereof, by transmitting/receiving the control signal to/from the external wireless base station and terminal, and controlling the resource manager, the QoS manager, the session manager, and the mobility manager. 3. The wireless access router of claim 1, wherein the mobile communication system function comprises a handover mobility management function, or a session establishment/disconnection function, or a QoS management function, or a radio resource and terminal/subscriber information management function, or any combination thereof. 4. The wireless access router of claim 1, wherein the mobility manager maintains information on the external wireless base station in a case of a handover of the external wireless base station in the wireless access router. 5. The wireless access router of claim 4, wherein the information on the external wireless base station comprises wireless base station identifier information, or router port information, or a call identifier, or QoS information, or any combination thereof. 6. The wireless access router of claim 1, wherein the access manager transmits/receives a control signal to/from external network elements and performs mobility management function, a terminal and subscriber authentication function, a session establishment/disconnection function for voice and image communication, and a QoS control function. 7. The wireless access router of claim 1, wherein a resource for the link establishment by the resource manager comprises a radio channel, or an Internet protocol address, or a subscriber number, or router port information, or a session, or call QoS information, or any combination thereof. 8. The wireless access router of claim 1, wherein the router comprises: a routing controller to process a routing protocol under control of the access manager; anda routing processor to perform a routing function and a forwarding function. 9. The wireless access router of claim 8, wherein the routing controller comprises: a routing interface to receive a control signal from the access manager and process the control signal;a routing protocol unit to process the routing protocol and generate and manage a routing table;a routing storage unit to store routing table information and information for finding an optimum path of a packet; anda routing application unit to analyze the routing control signal received from the access manager and control the routing function of the Internet protocol packets according to a radio resource for establishing a terminal link. 10. The wireless access router of claim 8, wherein the routing processor comprises: a routing processing controller to process a switching function, or a forwarding function, or a filtering function, or a routing function, or any combination thereof, of the Internet protocol packets according to a control signal of the routing controller;a routing processing manager to manage an internal signal processing function of the routing processor, or a forwarding table generation function of the routing processor, or a packet recombination function of the routing processor, or any combination thereof; anda forwarding unit to transmit the Internet protocol packets by opening a packet transmission path to a corresponding output port with reference to the forwarding table. 11. The wireless access router of claim 1, wherein the wireless access router is an integrated unit which houses the access manager and the router.
