Feature Changes
Previous Behavior: Earlier, SCTP downlink traffic passed through the default bearer instead of dedicated
bearer, when the received packet was matched with the packet filter, which was configured in either of the
following ways:
• Only source port or destination port was configured
• IP Address and port was configured
However, when the packet filter was configured for source and destination IP address, and the packet filter
matched with the received packet, traffic passed through the dedicated bearer.
New Behavior: Now, SCTP downlink traffic pass through the dedicated when the received packet is matched
with the packet filter, which was configured in either of the following ways:
• Source and destination IP address
• Only source port or destination port was configured
• IP Address and port was configured
