MT eCSFB call delivery with CPN Options proposed for Calling Party Number Presentation (CPNP). Note: Calling Party Number (CPN), Calling Party Information (CPI), and Calling Party Number Presentation mean the same thing the following contributions: Ericsson, -- CPN shown while on LTE, call accepted/rejected, requires General Page Message (GPM), CPN, Signal sent before Page Response on LTE (three options). –A r0 [E] eCSFB Call termination.doc Huawei – CPN delivered on LTE and shown when UE is in LTE. Bundling not used. –A r0-HW LTE-1xRTT eCSFB MT Call procedure.doc CTC/ZTE/QC – CPN transmitted when UE is in LTE, but presented to UE after moving 1x Traffic Channel (TCH). Bundles UHDM+AWI. –A r1_CTC_QC_ZTE_e1xCSFB MT call with call accepted for standalone IWS(UHDM+AWI).doc ALU/Mot/QC/KDDI/NEC/Hitachi – CPN forwarded in the HO messages to the target 1xBS. Bundling not used. –A r0 ALU Mot QC KDDI NEC Hit eCSFB MT Call flow procedure IWS-1xBS with HO.doc TSG-A is considering standardizing one or more solutions.

Summary of Potential Impacts to TSG-C for MT eCSFB w/HHO Ericsson proposals –C.S0097 might be affected, but can present CPN and signal to user when UE is in LTE Huawei proposals –C.S0097 affected but can present CPN when UE is in LTE –No bundling CTC/ZTE/QC sends AWI with UHDM in bundled GCSNA. –C.S0097 impact and bundles ALU/QC/Mot/KDDI/NEC/HIT CPI in Handoff messages. –supports C.S v1.0 (a.k.a. GCSNA 1.0) –No UE impact. No Bundling.
