Section: 10.5.4.15 Facility
Content: The purpose of the facility information element is to transport supplementary service related information. Within the scope of 3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ]  the content of the Facility information field is an array of octets. The usage of this transportation mechanism is defined in 3GPP TS 24.080[ Mobile radio interface layer 3 supplementary services specification; Formats and coding ]  [24]. The facility information element is coded as shown in figure 10.5.101/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ] . The facility is a type 4 information element with a minimum length of 2 octets. No upper length limit is specified except for that given by the maximum number of octets in a L3 message (see 3GPP TS 44.006[ None ]  [19]).
