Section: 10.5.4.4 Auxiliary states
Content: The purpose of the auxiliary states information element is to describe the current status of the auxiliary states of a call in the call control states "active" and "mobile originating modify" (see 3GPP TS 24.083[ Call Waiting (CW) and Call Hold (HOLD) supplementary services; Stage 3 ]  [27] and 3GPP TS 24.084[ Multi Party (MPTY) supplementary service; Stage 3 ]  [28]). The auxiliary states information element is coded as shown in figure 10.5.87/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ] , table 10.5.100/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ]  and table 10.5.101/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ] . The auxiliary states is a type 4 information element with 3 octets length.
