The BCFE is used to deliver the RRC services, which are required at the GC-SAP. The BCFE can use the lower layer services provided by the Tr-SAP and U-SAP. - Paging of idle mode UE(s) is controlled by the paging and notification control function entity (PNFE). The PNFE is used to deliver the RRC services that are required at the Nt-SAP. The PNFE can use the lower layer services provided by the Tr-SAP and U-SAP. - The Dedicated Control Function Entity (DCFE) handles all functions specific to one UE. The DCFE is used to deliver the RRC services which are required at the DC-SAP and can use lower layer services of U/A-SAP and Tr-SAP depending on the message to be sent and on the current UE service state. - In TDD mode, the DCFE is assisted by the Shared Control Function Entity (SCFE) location in the C-RNC, which controls the allocation of the PDSCH and PUSCH using lower layers services of U-SAP and Tr-SAP. - The Transfer ode Entity (TE) handles the mapping between the different entities inside the RRC layer and the SAPs provided by RLC.

20 19 NTE: Logical information exchange is necessary also between the RRC sublayer functional entities. ost of that is implementation dependent and not necessary to present in detail in a specification. Figure 1 shows the RRC model for the UE side and Figure 2a and Figure 2b show the RRC model for the UTRAN side. NTE: Some further clarification in the diagrams may be beneficial to acknowledge the fact that a DC-SAP for example might be offered over a dedicated channel (with RRC terminated in SRNC) whereas GC-SAP and Nt-SAP may be offered over BCCH, PCH respectively in which cases RRC is located in Node B. It could be concluded from the figure that these channels use the same SAP offered by RLC (Tr-SAP, U- SAP, A-SAP) whereas in fact they will use different SAPs, though the SAP type might be the same NAS NAS Access Stratum GC-SAP GC-SAP...

22 21 5 RRC Services provided to upper layers The RRC offers the following services to upper layers, a description of these services is provided in [2]. In case of DS-41 system, the SAPs and primitives defined in TS will be provided by RRC on UTRAN side as well as on UE side. - General Control - Notification - Dedicated control 6 Services expected from lower layers 6.1 Services expected from Layer Services expected from Layer 1 7 Functions of RRC The RRC performs the functions listed below, a more detailed description of these functions is provided in : - Broadcast of information provided by the non-access stratum (Core Network). - Broadcast of information related to the access stratum. - Establishment, maintenance and release of an RRC connection between the UE and UTRAN - Establishment, reconfiguration and release of Radio Bearers - Assignment, reconfiguration and release of radio resources for the RRC connection - RRC connection mobility functions - Routing of higher layer PDUs - Control of requested QoS. - UE measurement reporting and control of the reporting. - uter loop power control. - Control of ciphering. - Slow DCA. - Broadcast of DA relay node neighbour information - Collation of DA relay nodes neighbour lists and gradient information - aintenance of number of DA relay node neighbours - Establishment, maintenance and release of a route between DA relay nodes - Interworking between the Gateway DA relay node and the UTRAN - Contention resolution (TDD mode) - Paging/notification.

23 22 - Initial cell selection and re-selection in idle mode. - Arbitration of radio resources on uplink DCH - RRC message integrity protection - Timing advance (TDD mode) The following functions are regarded as further study items: - Congestion control. - Arbitration of the radio resource allocation between the cells. 8 RRC procedures 8.1 RRC Connection anagement Procedures Broadcast of system information UE UTRAN SYSTE INFRATIN Figure 3: Broadcast of system information General The purpose of this procedure is to broadcast system information from the UTRAN to idle mode- and connected mode UEs in a cell System information structure The system information elements are broadcast in system information blocks. A system information block groups together system information elements of the same nature. Different system information blocks may have different characteristics, e.g. regarding their repetition rate and the requirements on UEs to re-read the system information blocks. The system information is organised as a tree. A master information block gives s to a number of system information blocks in a cell, including scheduling information for those system information blocks. The system information blocks contain the actual system information and/or s to other system information blocks including scheduling information for those system information blocks. Figure 4 illustrates the relationship between the master information block and the system information blocks in a cell.

24 23 aster information block System information block 1 System information block 2 System information block n System information block 2.1 System information block 2.m Figure 4: The overall structure of system information System information blocks Table specifies all system information blocks and their characteristics. The area scope column in table specifies the area where a system information block is valid. If the area scope is cell, the UE shall read the system information block every time a new cell is entered. If the area scope is PLN, the UE shall check the value tag for the system information block when a new cell is entered. If the value tag for the system information block in the new cell is different compared to the value tag for the system information block in the old cell, the UE shall re-read the system information block. The UE mode/state column in table specifies in which UE mode or UE state the IEs in a system information block are valid. If the UE mode is idle mode, the UE shall use the IEs given by the system information block in idle mode. If the UE mode is connected mode, the UE shall use the IEs given by the system information block in connected mode. If the UE state is CELL_FACH, the UE shall use the IEs given by the system information block when in state CELL_FACH. In state CELL_DCH, the UEs fulfilling the Additional requirements column shall use the IEs given by the system information block when in state CELL_DCH. The transport channel column in table specifies where the system information block is broadcast. If the transport channel is BCH, the UE shall read the system information block on a BCH transport channel. If the transport channel is FACH, the UE shall read the system information block on a FACH transport channel. The scheduling information column in table specifies the position and repetition period for the SIB.
