Abstract
The present invention provides a method and an apparatus for providing radio access in a communication system by inter-working between at least two packet-based networks, such as heterogeneous cellular networks including a cellular network and an Internet Protocol (IP)-based wireless data network. The method includes enabling a packet routing path across the cellular and wireless data networks to provide a quality of service metric and an indication for mobility information associated with a user of a mobile device. The method further comprises transferring the quality of service metric and the indication for mobility information on the packet routing path in response to a service request across the networks. To provide wireless radio access, an IP-based communication system may use a wireless router, such as a base station router (BSR) and an inter-working unit. The inter-working unit may enable a packet routing path to provide a Quality of Service (QoS) metric and an indication for mobility information, such as mobility context information, associated with a user of a mobile device. In this way, instead of using a Mobile-IP client of the mobile device, the inter-working unit may …
