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).
– A30-20101025-010r0 [E] eCSFB Call termination.doc• Huawei – CPN delivered on LTE and shown when UE is in LTE. Bundling not used.
– A30-20101025-013r0-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.– A30-20100913-015r1_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.– A30-20101025-005r0 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.

Non functional
composite of proposals
This figure is not a call
flow. It is for ease in
undertanding key
differences between the
options
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.S0097-0 v1.0 (a.k.a. GCSNA 1.0)– No UE impact. No Bundling.
