Hi,
My two cents on context activation race: the collision between a network initiated context activation and UE initiated context activation. There is a potential issue if the modem and ofono try to assign the same CID at the same time Basically the sequence of AT commands looks like the following for the activation of PDP context: AT+CGDCONT=CID,X,Y,Z OK A+CGACT= CID,1 OK The collision can only occur if the +CGDCONT (or +CGDSCONT) command from Ofono is sent at the same time as PDP context activation URC from the modem, and both use the same CID. But in that case, the modem should not reply "OK" to the PDP context configuration command, but "ERROR". And Ofono should not consider that the PDP configuration command as successful. Moreover, the "OK" for the context configuration and the context activation URC are sent of the same control channel so they cannot be sent in parallel but only in sequence. Sjur, is that a correct assumption?
