BCM Bearer Control Mode indicates “mobile station only” or “mobile station / network”. If the BCM is “mobile station only”, the mobile station requests any additional Packet Data Protocol (PDP) contexts for the PDP Address / Access Point Name (APN) pair. If the BCM is “mobile station/network”, then the mobile station and the Packet Data Network GateWay (P-GW) or Gateway GPRS Support Node (GGSN) may request additional PDP contexts.
