Method and apparatus for providing multiple quality of service levels in a wireless packet data services connection
First Claim
1. A method for providing packet data services, the method comprising:
- establishing a single Point-to-Point Protocol (PPP) layer for communication by multiple data applications between a mobile station and a wireless network;
sending and receiving data through said single PPP layer using a first Radio Link Protocol layer having a reliable grade of service for a first type of data application; and
sending and receiving data through said single PPP layer using a second RLP layer having a low latency grade of service for a second type of data application, wherein the first RLP layer is configured for data retransmissions, and the second RLP is not configured for data retransmissions.

Abstract
The packets generated by each of multiple packet data applications are provided to a single Point-to-Point Protocol (PPP) stack and a single High-level Data Link Control (HDLC) framing layer to convert data packets into byte streams suitable for transmission through Radio Link Protocol (RLP) connections. Each of the resultant multiple byte streams is then provided to one of multiple RLP connections having different retransmission and delay properties. The RLP connection selected for sending data from each application is based on the grade of service most appropriate for the application. At the receiver, the data from the multiple RLP connections is provided to a single PPP stack.

20. A wireless network comprising:
a packet control function (PCF) apparatus comprising a control processor and a memory, wherein the control processor is configured to execute instructions stored in the memory for;
establishing a first Radio Link Protocol (RLP) layer having a reliable grade of service;
establishing a second RLP layer having a low latency grade of service different from the reliable grade of service;
receiving data from a mobile station through the first RLP layer; and
receiving data from the mobile station through the second RLP layer wherein the first RLP layer is configured for data retransmissions, and the second RLP is not configured for data retransmissions. - View Dependent Claims (21, 22, 23, 24)
