Interest growing in WLAN-3GPP interworking in two main areas: January 2013 doc.: IEEE 802.11-13/0092r0 January 2013 Interest growing in WLAN-3GPP interworking in two main areas: RAN (Radio Access Network) SA (System Architecture) Stephen McCann, RIM Stephen McCann, RIM
RAN Objective Currently being discussed within 3GPP working group RAN2 January 2013 doc.: IEEE 802.11-13/0092r0 January 2013 RAN Currently being discussed within 3GPP working group RAN2 Work item description available at: http://www.3gpp.org/ftp/tsg_ran/TSG_RAN/TSGR_58//Docs/RP-122038.zip Addressing interworking of WLAN and Cellular traffic at the radio level. Objective Project intends to identify opportunities for improved 3GPP radio access and WLAN interworking, in particular through the use of extended knowledge at radio layers.

SA: Optimised mobility taking into account 3GPP RAT type January 2013 doc.: IEEE 802.11-13/0092r0 January 2013 SA: Optimised mobility taking into account 3GPP RAT type Release 12 study on Optimised Offloading to WLAN in 3GPP RAT mobility A study currently being discussed within 3GPP WG SA2 (Work item code: FS_WORM) Work item description available at: http://www.3gpp.org/ftp/tsg_sa/TSG_SA/TSGS_56//Docs/SP-120261.zip Objective Identifying extensions to ANDSF ISRP and possibly ISMP policies in order to enable policy differentiation of 3GPP RATs (e.g. E-UTRAN versus UTRAN, GERAN vs. UTRAN) with respect to WLAN. Studying how mobility between 3GPP RATs could be performed in a more optimised way taking into account the possible availability of WLAN. Stephen McCann, RIM Stephen McCann, RIM
