10 Error handling

29.1193GPPGPRS Tunnelling Protocol (GTP) specification for Gateway Location Register (GLR)Release 17TS

The error handling on the interface between the IM_GSN and other nodes is the same as that in the network without the GLR. See 3GPP TS 29.060. One exception is that the IM_GSN doesn’t have a Restart Counter because the IM_GSM stores no PDP and MM context and therefore the synchronisation of the status of these with other GSNs is not needed.
