Concepts

This section describes the concepts related to the packet data telephony. The packet data telephony API provides interface to access the packet switched service of a network.

• Architecture
  This section provides the architectural relationship between the packet data telephony classes.
• What is the Packet Service ?
  The packet service enables the client applications to control the packet switched connections.
• What is the Packet Context ?
  The packet context encapsulate the functions related to the context of a packet switched network connection. The context of a connection relates to factors such as the protocol type, the access point to the network and the DNS and authentication parameters.
• What is the Packet Quality of Service ?
  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.
