Protocols NodeB RNC RRC NBAP ALCAP

Protocols : RRC functions Radio Ressource Control  Assigns and manages the radio resources for the mobile Reaction to commands from the Core Network Reaction to request or measurements provided by the mobile Reaction to request or measurements provided by the Node Bs

Protocols : RRC functions RRC functions – RRC connection management – RRC states management – System information broadcast – Paging management – Cell selection – Mobility management in UTRAN – Configuration of radio bearer, transport & physical channels – Ciphering and integrity configuration

Protocols : NBAP functions Common NBAP functions – Cell Configuration Management – Common Transport Channel Management – System Information Mangement – Resource Event Management – Configuration alignment – Measurement on Common Resources

Protocols : NBAP functions Dedicated NBAP functions – Radio Link Management – Radio Link Supervision – Compressed Mode Control – Measurement on Dedicated Resources – DL Power Drifting Correction [FDD]. – Reporting of General Error Situations.

Protocols : ALCAP ALCAP functions – Creation and release of AAL2 channels – Reset of ALL2 ressources
