Quality of service support at an interface between mobile and IP network
First Claim
1. A method for establishing a flow comprising:
- receiving at a wireless network node from a mobile station a first request message, said first request message comprising at least one quality of service parameter for the flow;
after receiving the first request message, the wireless network node granting a plurality of quality of service parameters; and
sending from the wireless network node to a packet data switching node a registration request message, the registration request message comprising one or more of the granted quality of service parameters.

Abstract
A signaling regimen between a mobile station MS, a radio node RN, and a packet data switching node PDSN enables a quality parameter to be applied to packets moving between a mobile and a CDMA2000 network. The MS creates a new flow for packets of a certain data type and sends a related quality parameter for that flow to the BS. The BS determines whether an existing or new service instance will carry the new flow, and obtains authorization for the service instance to meet the quality parameter from the PDSN. The BS or PDSN builds a map between flow and a policy that ensures the quality is met, and the map is used to place different packets into the appropriate flow and service instance. Policies and enforcement may differ on uplink and downlink.

14. A signaling protocol method to enable an assured quality on a flow comprising:
-
a radio node receiving from a mobile station a request that includes at least one quality of service parameter for the flow; after the receiving, the radio node sending to the mobile station a grant of a set of quality of service parameters for the flow; after the receiving, the radio node further sending a registration request to a packet data switching node that includes the granted set of quality parameters for the flow; and after sending the registration request, the radio node receiving from the packet data switching node a registration reply that authorizes the flow. - View Dependent Claims (15, 16, 18, 22, 23)

17. A wireless network node comprising:
-
a receiver configured to receive a quality of service parameter request message, the request message comprising at least one quality of service parameter for a flow; a controller configured to determine and to grant at least one quality of service parameter for the flow in response to the request message being received at the receiver; and a transmitter configured to send a registration request message to a packet data switching node in response to the controller determining and granting, the registration request message comprising the granted at least one quality of service parameter; and
the transmitter configured also to send a reply message comprising the granted at least one quality of service parameter to the mobile station. - View Dependent Claims (19, 24)

20. A wireless network node comprising:
-
means for receiving from a mobile station a quality of service parameter request message that comprises at least one quality of service parameter for a flow; controller means for determining and granting at least one quality of service parameters for the flow after the request message is received at the means for receiving; and means for sending, in response to the controller means determining and granting, a registration request message comprising the granted at least one quality of service parameter to a packet data switching node; and
also for sending a reply message comprising the granted at least one quality of service parameter to the mobile station. - View Dependent Claims (21)
