Bearer Control Mode (BCM) selection at IP-CAN session establishment or IP-CAN session
modification (as a consequence of an SGSN change). It will be done using the "PCC Rule Request"
procedure.
If the Bearer-Control-Mode AVP is not received from PCRF, the IP-CAN session is not terminated.
The value negotiated between UE/SGSN/GGSN is considered as the BCM. The following values are
considered for each of the service types:
 GGSN: The negotiated value between UE/SGSN/GGSN is considered.
In the following scenarios UE_ONLY is chosen as the BCM:
Scenario 1:
 UE-> UE_ONLY
 SGSN-> UE_ONLY
 GGSN-> UE_ONLY
 PCRF-> NO BCM
Scenario 2:
 UE-> UE_ONLY
 SGSN-> UE_ONLY
 GGSN-> Mixed
 PCRF-> NO BCM
 GTP-PGW: BCM of UE_NW is considered.
 IPSG: BCM of UE_ONLY is considered.
 HSGW/SGW/PDIF/FA/PDSN/HA/MIPV6HA: BCM of NONE is considered.
