Signaling quality of service class for use in multimedia communicatations
First Claim
1. A method in an access network coupled to a packet data network, where the access network includes a radio access network coupled to a packet-switched access network which includes an access point coupled to a multimedia system that provides multimedia session services, comprising:
- generating a message requesting a bearer between the mobile terminal and the access point that includes a signaling quality of service (QoS) indicator, anddetecting the signaling QoS indicator in the message, and in response, establishing a bearer between the mobile terminal and the access point that supports a pre-established signaling QoS profile.

Abstract
A signaling bearer quality of service profile is pre-established and configured in various nodes in an access network. This is a new quality of service class designed to meet the needs of signaling bearers in multimedia sessions. A message requesting a bearer to support a communication between a mobile terminal and an access point to a packet data network is generated. That message includes a signaling quality of service indicator, which when detected, causes a bearer to be established between the mobile terminal and the access point in accordance with the pre-established signaling quality of service profile. The pre-established signaling quality of service profile typically includes low delay and low bit error rates in addition to high priority and accommodation of bursty traffic patterns. A signaling usage indicator may also employed to implement a standard set of minimum signaling bearer capabilities.
