CSCuo63213 - MME: SLs interface support
Feature Changes
SLs Interface Support
Important:
For this release, this feature is Lab/Trial Quality only.
The SLs interface is used to convey LCS Application Protocol (LCS-AP) messages and parameters between the MME
to the Evolved Serving Mobile Location Center (E-SMLC). It is also used for tunnelling LTE Positioning Protocols
(LPP between the E-SMLC and the target UE, LPPa between the E-SMLC and the eNodeB), which are transparent to
the MME.
