2. INTERFACES Cu Interface: electrical interface between the USIM and ME. Uu Interface: radio interface between UE and UTRAN . Iu Interface: this connects UTRAN to the CN. Iur Interface: allows soft handover between RNCs . Iub Interface: the Iub connects a Node B and an 3. GENERAL ARCHITECTURE Radio interface protocols can be divided into twocategories: horizontal layers and vertical planes. Horizontal layers can be broadly divided into twocategories: ACCESS STRATUM(AS) and NON-ACCESSSTRATUM (NAS). Vertical planes can be broadly classified into USERPLANE and CONTROL PLANE which takesplace over Uu and Iu interfaces. 4. GENERAL ARCHITECTURE 5. CONTROL PLANE Protocols for controlling the radio access bearersand the connection between the UE and thenetwork. Has three layers: physical layer, data-link layerand network layer. Data link layer comprises of MAC and RLC. Network layer comprises of RRC ,MM,GMM and CM. RLC,MAC and PHY are also present in USER PLANE. 6. USER PLANE U-plane is responsible for the transfer of user data, such as voice or application data through the access stratum. It consists of Applications ,CN protocols and RAN protocols. CN comprises of Data Protocols such as IP,PPP,OSP and others. RAN comprises of PDCP,BMC,RLC,MAC and PHY. 7. MOBILITY MANAGEMENTMobility management allows mobile phones towork by tracking where the subscribers are,allowing calls, SMS and other mobile phoneservices to be delivered to them.Functions: Location management Network registration Security function 8. MM PROCEDURESCOMMON PROCEDURES:The common procedures basically include: TMSI reallocation procedure. Authentication procedure. Identification procedure.Information procedure.SPECIFIC PROCEDURE: Normal location updating procedure; Periodic updating procedure; IMSI attach procedure. 9. CONNECTION MANAGEMENT PROCEDURES: Establish, Maintain release MM connection between the mobile station andthe network over which an entity of the upper CMlayer can exchange information with its peer. 10. LOCATION UPDATE The cells broadcast their cell identities. The MS periodically listens to the broadcast cellidentity, and compares it with the cell identity storedin the MSs buffer. If the comparison indicates that the location hasbeen changed, then the MS sends the locationupdate message to the network. It takes place either when MS detects when locationhas been changed or periodically. 11. CONNECTION MANAGEMENT Connection management (CM) sub layer consistsof Call control Supplementary services Short message service Session management GPRS SMS 12. Call Control Call-establishment proceduresA call can be either a mobile-originated call (MOC) ora mobile terminated call (MTC). Call-clearing procedures It can be initiated either by the UE or by the network. Call-information-phase proceduresInforms the user about call-related events, such asuser suspension or resume Miscellaneous proceduresinclude in-band tones and announcements, statusinquiry, and callreestablishment. 13. Supplementary Services value-added services that may or may not beprovided by the network operator advice of charge (AoC), call forwarding (CF),and call waiting (CW) supplementary services services belong to the NASShort Message Service non-real-time service a store and-forward service in which messages can be stored on the SMSC an delivered when the destination UE is available. 14. Session Management protocol is to support packet data protocol(PDP)context handling of the user terminal. communicating entities do need to know about thecharacteristics of the data to be transferred, it isperformed by the PDP context-activation procedureGPRS Short Message Service protocol task handles the SMS service while the UE isattached to the PS CN 15.
