Systems and Methods for Improved Mobility and Quality of Service in a Wireless Network
First Claim
1. For a mobile node visiting a packet-switched wireless access network, said access network using a tunnelling-type micro-mobility protocol and a Quality of Service (QoS) routing protocol to route packet data to and from said mobile node, and comprising an access router to which said mobile node may attach, a mobility agent and a gateway, a method of configuring said access network to route packet data toward said mobile node which method comprises:
- receiving in said access network a handover indication of said mobile node or a login request therefrom;
in response to receiving said handover indication or login request, computing a QoS route for said mobile node at a location in said access network remote from said mobility agent, which QoS route is useable to route packets between said mobility agent and said mobile node; and
transmitting said QoS route and said handover indication or login request from said remote location toward said mobility agent;
wherein upon receipt of said handover indication or login request, said mobility agent may handle both mobility configuration and QoS route configuration for said mobile node as part of said network layer handover.

Abstract
For a mobile node visiting a packet-switched wireless access network, said access network using a tunnelling-type micro-mobility protocol and a Quality of Service (QoS) routing protocol to route packet data to and from said mobile node, and comprising an access router to which said mobile node may attach, a mobility agent and a gateway, a method of configuring said access network to route packet data toward said mobile node which method comprises the steps of: (a) receiving in said access network a handover indication of said mobile node or a login request therefrom; (b) in response to said handover indication or login request computing a QoS route for said mobile node, which QoS route is useable to route packets between said mobility agent and said mobile node; (c) performing step (b) at a location in said access network remote from said mobility agent; and (d) transmitting said QoS route and said handover indication or login request from said remote location toward said mobility agent; whereby upon receipt of data transmitted in step (d) said mobility agent may handle both mobility configuration and QoS route configuration for said mobile node as part of said network layer handover.

21. A packet-switched wireless access network comprising:
-
an access router to which said mobile node may attach; a mobility agent; and a gateway, wherein, in response to either a handover indication or a login request being made by a mobile node, a QoS route for said mobile node is generated in said wireless access network at a location remote from said mobility agent, which QoS route is useable to route packets between said mobility agent and said mobile node; wherein said QoS route and said handover indication or login request are transmitted from said remote location toward said mobility agent; and when said QoS route and said handover indication or login request are received at said mobility agent, said mobility agent handles both mobility configuration and QoS route configuration for said mobile node.

22. A computer-readable memory storing computer-executable instructions for operating an packet switched wireless access network, the memory comprising:
-
computer-executable instructions for receiving in said access network a handover indication of said mobile node or a login request therefrom; computer-executable instructions for computing a QoS route for said mobile node, which QoS route is useable to route packets between said mobility agent and said mobile node in response to said handover indication or login request; and computer-executable instructions for transmitting said QoS route and said handover indication or login request from said remote location toward said mobility agent; wherein said computer-readable memory is remote of said mobility agent. - View Dependent Claims (23, 24)
