Section: 10.5.5.24 Inter RAT information container
Content: The purpose of the Inter RAT information container information element is to supply the network with Iu mode related information that needs to be transferred at PS inter-system handover to Iu mode (see 3GPP TS 43.129[ None ]  [113]). The Inter RAT information container information element is coded as shown in figure 10.5.150/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ] . The Inter RAT information container information element is a type 4 information element with a minimum length of 3 octets and a maximum length of 250 octets. The Inter RAT information container contains: - predefined configuration status information; - mobile station security information to be used after handover to Iu mode, which includes the START-PS value that is stored by the MS at handover from Iu mode to A/Gb mode (see 3GPP TS 33.102[ 3G security; Security architecture ]  [5a]); and/or - the specific Iu mode radio capabilities of the mobile station, i.e. UE RAC (see 3GPP TS 25.331[ None ]  [23c]). Figure 10.5.150/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ] : Inter RAT information container information element The value part of the Inter RAT information container information element is the INTER RAT HANDOVER INFO as defined in 3GPP TS 25.331[ None ]  [23c]. If this field includes padding bits, they are defined in 3GPP TS 25.331[ None ]  [23c].
