Section: 11.8 Non-IP data transfering over SGi 11.8.1 General
Content: When support of Non-IP data is provided at the Gi/SGi interface, different Point-to-Point (PtP) tunneling techniques may be used. When using PtP tunneling by UDP/IP encapsulation subclause 11.8.2 below shall be followed. Other techniques as described in clause 11.8.3 below may be used. The Gi/SGi based Non-IP data delivery is applicable to the User Plane CIoT EPS Optimization and the Control Plane CIoT EPS Optimization (see 3GPP TS 23.401[ General Packet Radio Service (GPRS) enhancements for Evolved Universal Terrestrial Radio Access Network (E-UTRAN) access ]  [77] and 3GPP TS 23.060[ General Packet Radio Service (GPRS); Service description; Stage 2 ]  [3]).
