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.

The context is associated with a particular packet service.

Contexts for each network type are supported by different member classes in the RPacketContext:

Symbian OS provides the authentication parameters to support CHAP and PAP authentication methods. Previously only PAP authentication was supported. The CHAP authentication is more secure than the PAP authentication. The additional functions are:

This API is implemented by RPacketContext.

Packet context functions

The RPacketContext API functions enable the clients to do the following:

  • Obtain a secondary packet context from an existing packet. The second packet uses the same context information. The Quality of Service information is not used.

  • Configure the Quality of Service specifications of Release99 and Release4 in the packet context.

  • Modify the negotiated QoS of an active context.

  • Add, remove and change the packet filters in the Traffic Flow template of a context. The clients can also create and delete the Traffic Flow templates.

  • Discover context information for a network interface (NIF) level.

  • Retrieve the current packet network release mode to receive roaming notification between the release modes.
