Creating the materials: – – The purpose of this template is to harmonise the contents of this customer delivery and to provide you guidance as to which information is typically requested by the customers on features. When relevant neighbours are missing from the SIB11. SIB11bis solves an inconsistency problem in 3GPP TS 25.331. Confidental 5 © Nokia Siemens Networks DRAFT <dnxxxxxxx> Issue <y-y> . which may lower the performance in call success rates. In demanding environments. but in the specifications the physical size of SIB11 data has capacity only for 47 cells. the UE cannot make optimal cell selection. which has prevented the usage of complete neighbouring cell lists for idle mode UEs. 3GPP R6 introduces SIB11bis. System Information Block type 11bis (SIB11bis) provides extension segments for SIB11. 32 inter-frequency and 32 inter-system neighbouring cells for idle mode UEs.Introduction This feature belongs to operating software. the interfrequency and inter-system neighbour cell lists may remain incomplete. which allows operator to define 32 intra-frequency. All these neighbours were originally intended to be included in SIB11. As the intra-frequency neighbours are typically given the highest priority. the existing size of SIB11 may not be enough. SIB11bis is a backward compatible solution to correct the problem in SIB11. Benefits for the operator Complete neighbouring cell lists can be provided to guarantee the optimal cell re-selection and end-user QoS. Confidental 6 © Nokia Siemens Networks DRAFT <dnxxxxxxx> Issue <y-y> . SIB11 is guaranteed to be able to contain 47 as maximum number of neighbors with any configuration (35 if HCS is used). After the decoding UE has full knowledge of all defined neighbouring cells Confidental 7 © Nokia Siemens Networks DRAFT <dnxxxxxxx> Issue <y-y> . Then the encoded RRC SYSTEM INFORMATION message and the transmission schedule is transmitted to BTS using NBAP: SYSTEM INFORMATION UPDATE REQUEST message. inter- frequency and/or inter-system) becomes greater than can be encoded to • • • • SIB11. BTS then decodes the NBAP message and starts to transmit RRC SYSTEM INFORMATION messages according the given schedule. UE then receives and decodes the contents the RRC SYSTEM INFORMATION message. The amount of neighbouring cells that can fit to SIB11 depends on the parameter values of neighbouring cells. SB1 and SIB18 are updated accordingly and transmission schedule is calculated.Functional description • When the amount of defined neighbouring cells (intra-frequency. SIB11bis is taken to use. The remaining neighbouring cells are encoded to SIB11bis and MIB. SB1 and SIB18 • Update to MIB and SIB1 is the support of the new SIB type extension IE • Update to SIB18 is the support of listing the PLMN identities for the cells present in SIB11bis Confidental 8 © Nokia Siemens Networks DRAFT <dnxxxxxxx> Issue <y-y> .331 are done to contents of MIB.Implementation in RAN • New SIB type is introduced to NBAP and RRC protocols • The neighbouring cells that do not fit into SIB11 are packed to SIB11bis • When SIB11bis is used corresponding updates required by the 3GPP TS 25.
