5.2.1 Configuration of LCS entities for GERAN

The configuration of LCS entities for GERAN is presented in figure 2. In the figure, all the functions are considered implemented in different logical nodes. If two logical nodes are implemented in the same physical equipment, the relevant interfaces may become internal to that equipment.

NOTE: Lgd interface is applicable only for an SGSN supporting EPS based interfaces and protocols.

5.2.2 Configuration of LCS entities for UTRAN

The basic configuration of UTRAN LCS is presented in figure 3. The SMLC functionality is integrated in SRNC or, in case a Stand-Alone SMLC entity (SAS) is present, split between SRNC and SMLC.

NOTE: Lgd interface is applicable only for an SGSN supporting EPS based interfaces and protocols.

5.2.3 Configuration of LCS entities for E-UTRAN

The basic configuration of E-UTRAN LCS is presented in figure 3a.
