Section: 10.5.6.20 WLAN offload acceptability
Content: The purpose of the WLAN offload acceptability information element is to indicate whether traffic can be offloaded using a PDN connection via a WLAN, or not. The values "offloading the traffic of the PDN connection via a WLAN when in S1 mode is acceptable" and "offloading the traffic of the PDN connection via a WLAN when in Iu mode is acceptable" map to "indication that the PDP context is offloadable" as defined in 3GPP TS 23.060[ General Packet Radio Service (GPRS); Service description; Stage 2 ]  [74] and 3GPP TS 23.401[ General Packet Radio Service (GPRS) enhancements for Evolved Universal Terrestrial Radio Access Network (E-UTRAN) access ]  [122]. The value "offloading the traffic of the PDN connection via a WLAN when in S1 mode is not acceptable" and "offloading the traffic of the PDN connection via a WLAN when in Iu mode is not acceptable" map to "indication that the PDP context is not offloadable" as defined in 3GPP TS 23.060[ General Packet Radio Service (GPRS); Service description; Stage 2 ]  [74] and 3GPP TS 23.401[ General Packet Radio Service (GPRS) enhancements for Evolved Universal Terrestrial Radio Access Network (E-UTRAN) access ]  [122]. The procedures in 3GPP TS 23.060[ General Packet Radio Service (GPRS); Service description; Stage 2 ]  [74] when the MS receives the UTRAN offload acceptability value in A/Gb mode or Iu mode apply. The procedures in 3GPP TS 23.401[ General Packet Radio Service (GPRS) enhancements for Evolved Universal Terrestrial Radio Access Network (E-UTRAN) access ]  [122] when the MS receives the E-UTRAN offload acceptability value in S1 mode apply. The WLAN offload acceptability information element is coded as shown in figure 10.5.6.20-1/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ]  and table 10.5.6.20-1/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ] . The WLAN offload acceptability is a type 1 information element.
