The 3rd Generation (3G) Framing Protocol (FP) provides the data and control frame procedures as described in 3GPP specifications. FP is a user plane protocol that exists on the Iub and Iur interfaces. The FP software can work on Radio Network Controllers (RNC) as well as Node Bs. The following features are supported in each both the RNC and Node B behavior models.

DCH FP service provides following functions on the Iub and Iur interface:

  • Transport of TBS for dedicated transport channels
  • Support of transport channel synchronization
  • Support of node synchronization
  • Transport of outer loop power control information from SRNC to Node B
  • Transport of radio interface parameters update information from SRNC to Node B
  • Transport of DSCH TFCI signaling information from SRNC to Node B
  • Supports Transport Bearer replacement for DCH
  • Transport of Rx Timing Deviation from Node B to SRNC

CCH FP service provides following functions on the Iub interface:

  • Transport of TBS for common transport channels
  • Transport channel synchronization for common transport channels
  • Support of node synchronization mechanism
  • Supports transport bearer replacement for DSCH channel

CCH FP service provides following functions on the Iur interface:

  • Transport of MAC-c/sh SDUs from the DRNC to the SRNC for RACH common transport channels
  • Transport of MAC-c/sh SDUs from the SRNC to the DRNC for FACH common transport channel
  • Flow Control between MAC-d and MAC-c/sh for FACH common transport channel
  • Transport of MAC-c/sh SDUs between the SRNC and the DRNC for USCH and DSCH common transport channels
  • Flow Control between MAC-d and MAC-c/sh for DSCH common transport channel
  • Transport of MAC-d flows between the SRNC and the DRNC for HS-DSCH common transport channels
  • Flow Control between MAC-d and CRNC HS-DSCH Flow Control

Trillium 3G FP software enables telecom equipment manufacturers of RNCs, Node Bs or other products to:

  • Accelerate time to market
  • Reduce development costs
  • Reduce project risk of internally developed FP applications

Product deliverables consist of C source software, documentation, training, a warranty and technical support.

PRODUCT INFORMATION

The 3G FP software is a portable C source code with modular design and simple interfaces which can be easily ported into any environment under any operating system.

Extensive debugging capabilities are provided including debug printing and function traces. This is useful in embedded systems in which other symbolic debugging is unavailable. Extensive error checking and recovery mechanisms are available to deal with normal error conditions, which can be enabled using compile time options.

FEATURES + BENEFITS

  • Can operate on both an RNC and Node B to provide the Iub and Iur interfaces.
  • Provides DCH and CCH features.
  • Release99, Release4, and Release5 compliant.
  • Recovers from detected errors and notifies unrecoverable errors.
  • Conforms to Trillium Advanced Portability Architecture (TAPA)
  • Benefits of licensing Trillium software from Continuous Computing
