Trends / Challenges
► Mobile
broadband has taken off
High bandwidths
• High user peak rates
• Low network latency
•
► Smart
Phones (iphone etc) require intensive signaling, i.e. control
processing.
► WCDMA
follows the LTE track in development
Competitive performance with HSPA+
• Support for flat architecture
•
► Home
base-station, will 2010/11 be the break through?
► All IP? Investments in ATM needs smooth migration, i.e. IP over ATM.
► Content Caches in field to offload main pipe to Internet?

The SEC dequeues from its highest priority FQ, an

The Shared Descriptor is only fetched once per FQ
dequeue, and a configurable max number of FDs can be
processed from that FQ.

Challenge: Voice Packets
►Voice
Packets are ciphered/formatted in RNC (3G) and (e)NB (LTE
and 3G flat architecture).
►Voice
packets are large to the number but small to the size (~20
bytes).
►Typically
each active flow has a packet per ~20ms, i.e. it is not
possible to group packets of same flow or latency will increase and
phone conversation will not work (lag severely).
►Hardware
Acceleration is a big benefit but overhead/byte of sending
to accelerator has been a big problem since packets are so small.

RLC / MAC / FP flow on P4080: Example A
►
User data assembled in memory, from GTP-U.
►
When MAC flow control indicates that we can send data:
Core:
1. Checks retransmission buffer.
2. Checks status transmission buffer.
3. Creates RLC headers with status.
4. Checks if C/T MUX is used.
5. Adds pointers to segments and RLC headers.
6. Concatenation/piggyback/pad. of last user-data packet
7. Saves pointers for retransmission buffer
8. Creates FP header/tail.
SEC: segments, adds header, bitshift and cipher. Adds FP header/tail and
computes CRC-7 and CRC-16.
