RRC Software

The Radio Resource Control (RRC) protocol is used in the control plane of the Third Generation (3G) wireless stack. The RRC software is the implementation of the RRC protocol specification on the UTRAN side as specified in 3GPP TS 25.331 for the Universal Mobile Telecommunication System (UMTS). The RRC layer configures the RLC, MAC, PDCP, and BMC layers. The RRC layer decodes the RRC messages and passes the information to the RRC user (RRU) layer. Also, the RRC layer encodes the RRC messages and passes the encoded message to UE.

The RRC user performs policy related functions such as, measurement control, mobility management, radio resource management, and setting up of channels. The RRC user also invokes services of the RRC layer to send messages to the UEs. The following diagram illustrates the UMTS radio interface protocol architecture.

Trillium RRC software enables telecom equipment manufacturers of Node Bs, Radio Network Controllers, Femtocells, Femtocell Gateways, test equipment, or other products to:

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

Product deliverables consist of C source software, documentation, training, the Trillium XML Test Architecture (XTA), a warranty and technical support.
