building pdrs and fars in CreateSession

[ranomine]

Hi @louisroyer,

Thanks a lot for your nice code.
Would you have by chance a small example of building fars and pdrs MAPs to be used in CreateSession?

Many thanks

Roch.

To create a FarMap, you have to first create an array of CreateFar IEs, and then you can call NewFARMap(fars []*ie.IE) (farmap *FARMap, err error, cause uint8, offendingIE uint16)

	import "github.com/wmnsk/go-pfcp/ie"
	createFar := ie.NewCreateFAR(
		ie.NewFARID(1), // FAR ID is 1
		ie.NewApplyAction(0x01), // set the DROP flag
	),
	f := make([]*ie.IE, 0)
	f = append(f, createFar)
	farMap, _, _,_ := NewFARMap(f)
	
	// same (but not detailed here) for pdrMap
	// …
	a.CreateSession(pdrMap, farMap)

This is the same thing for PDRs with NewPDRMap(pdrs []*ie.IE) (pdrmap *PDRMap, err error, cause uint8, offendingIE uint16), and CreatePDR IE (containing at least a PDR ID, a Precedence, a PDI and a FAR ID).

If your question was about what they should contain exactly, everything is detailed on TS 129.244.

Perfect!

Merci beaucoup :)
