The packet Quality of Service (QoS) encapsulates functions to configure the QoS options for a particular context in GSM networks or service configuration in CDMA networks.
QoS parameters refer the parameters like minimum throughput rates, requested throughput rates, maximum delay and accepted loss rate.
This functionality is implemented by the RPacketQoS class. A context and service configuration is represented by the RPacketContext.
The packet QoS provides the client applications the following functions:
to set the minimum and requested QoS profile parameters
to get the negotiated QoS profile parameters
to query the QoS capabilities of the packet-switched service and notify the clients of a change in their negotiated QoS profile
The QoS is not network dependent. Some network dependent features is included if the telephony server provides full support QoS for different packet services.
Note: RPacketQoS does not depend on the network. The networks like GPRS Release 97, Release 98, Release 99,Release 4, CDMA and CDMA2000 have different QoS specifications. RPacketQos must include the network specified features to provide QoS in these networks.
