3.1 Vocabulary
– Coverage Class: See definition in 3GPP TS 43.064 [10].
– CS/PS coordination enhancements: refers to an improved CS/PS domain registration coordination function when rerouting is performed in a MOCN or in a GWCN configuration for network sharing. The improved CS/PS domain registration coordination is achieved by extended signalling between the BSS and the CN nodes (see 3GPP TS 23.251 [43]).
– Dedicated Core Networks: Dedicated Core Networks is an optional feature that enables an operator to deploy multiple dedicated core networks within a PLMN where each dedicated core network node may be dedicated to serve specific type (s) of subscribers. The selection of the Dedicated Core Network is based on “UE Usage Type” obtained from the HSS/HLR and operator specific configuration in the SGSN (see 3GPP TS 23.401 [49]).
– EC operation: See definition in 3GPP TS 43.064 [10].
– Extended DRX (eDRX): see 3GPP TS 21.905 [1].
– MS assisted Dedicated Core Network selection: MS assisted Dedicated Core Network selection is an optional feature wherein the selection of the Dedicated Core Network to which a BSS routes LLC PDUs, in addition to the selected PLMN, is based on the “DCN-ID” value provided by the MS (see 3GPP TS 23.401 [49]).
– Network sharing: network sharing is an optional feature that allows different core network operators to connect to the same shared radio access network in a MOCN configuration, and to the same shared radio access network and core network nodes in a GWCN configuration (see 3GPP TS 23.251 [43]). When network sharing is in use within a given cell, the network broadcasts within system information the PLMN identities of the PLMNs sharing the cell. A mobile station supporting network sharing uses this information for its PLMN (re)selection processes and indicates the selected PLMN to the BSS.
– Null-NRI: Has the same format as the NRI and is used to identify the group of SGSNs that belong to a DCN within a PLMN. A ‘null-NRI’ indicates to a radio node (BSC/RNC) that the NAS Node Selection Function shall be used for selecting a CN node to receive a message (see 3GPP TS 23.236 [21]).
– SGSN Group ID: A SGSN Group ID identifies a Dedicated Core Network (DCN) within the PLMN, i.e. the group of SGSNs that belong to a DCN within a PLMN, see 3GPP TS 23.401[49].
