Radio Network Objects (cont.)
• RNC : network element in a radio access network, which is in charge of controlling the use and
integrity of the radio resources
• WBTS : base transceiver station of the third generation network
• WCELL : cell of the third generation network
• CoCo : managed logical object in the radio network configuration management, displaying the
transmission in the Iub interface and specifying the Iub link configuration to the ATM level
• FMCx : managed object in the radio network configuration management, including the parameters
for measuring the transmission frequencies
• HOPx : information indicating handover decision parameters which control the handover from the
serving cell to a specified neighbouring cell
• ADJx : relationship that is defined between a wideband code division multiple access (WCDMA) cell
and a neighbouring cell
• WSMLC : serving mobile location centre that is used in a third generation network and that has
specific parameters for each radio network controller
• WLCSE : logical object that contains WCDMA cell specific location parameters that are needed for
the positioning algorithms

AAL2 Multiplexing
• Feature since RAN04
• Enable statistical multiplexing gain
• Save Iub transmission capacity
• Reduce the number of VCC between BTS and RNC

Iub Dimensioning (cont’)
• Iub capacity = U-Plane + CNBAP + DNBAP + AAL2sig + O&M
• 150 CPS (~ 64 kbps) of O&M is recommended per BTS.
• Min CNBAP, DNBAP and AAL2SIG is 39 CPS each and max 2100 per WAM
• The CNBAP bandwidth requirement depends on,
• the call setup
• radio link addition (soft handover)
• the RRI period
• The DNBAP capacity requirement depends on,
• the number of calls
• call lengths
• RLM report period

Iub Dimensioning (cont’)
• Signaling load 6 – 7 % of Iub capacity
