PAGE 2 Background In C23-20021021-013, Qualcomm proposed Page w/Channel Assignment, where the MS goes directly to the Traffic Channel without sending a page response. In C23-20030217-020, Motorola proposed a RESPONSE_IND field for the Page w/Channel Assignment, to indicate to the mobile whether or not a page response is required. The values of RESPOND_IND are as follows: –’00’: MS does not send page response (i.e. same as Qualcomm proposal) –’01’: MS must send page response, in assured mode –’10’: MS must send page response, in unassured mode The page response is useful if the BS wants early confirmation that the MS is “present”, while still reducing call setup time –Page response on access channel is currently significantly faster than TCH acquisition QUESTION: what is the relative benefit of ’10’ compared to ’01’?

PAGE 4 Assumptions Two important metrics: – “Call Setup Time”: Time for MS to arrive on Traffic Channel, defined here to be the time from the MS receiving the GPM to the MS receiving the BS Ack Order on the traffic channel –“MS Declared Present”: Time when BS has sufficient information to declare MS “present”, defined here to be the time from the MS receiving the GPM to the time the BS either successfully receives the PRM or the BS Ack Order being sent on the F- TCH, whichever event comes first MS time stamps used in the analysis are average values derived from mobile logs ATime from MS receiving GPM to BS receiving PRM (assumption: transmitting BS Ack Order takes 80 ms) 210 ms BTime from MS receiving GPM to MS receiving BS Ack Order on PCH290 ms CTime from MS receiving GPM to MS receiving ECAM483 ms DTime from MS receiving ECAM to MS receiving BS Ack Order on F-TCH580 ms EAccess probe retransmission delay (assumption: ACC_TMO = 1, PAM_SZ = 2, MAX_CAP_SZ = 3, ACH_SZ = 4) 540 ms FTime from MS receiving ECAM to BS acquiring TCH preamble (assumption: transmitting BS Ack Order takes 40 ms) 540 ms

PAGE 6 Observations For “MS Declared Present”, page response modes (’01’ and ’10’) are 330 ms faster than no page response mode (’00’) –Page response modes still improve call setup time, but without delaying “MS Declared Present” indication –Page response mode should be available as an option For the two page response modes, unassured mode (’10’) outperforms assured mode (’01’) –Unassured mode (’10’) is the best option for when fast “MS Present” indication is needed Slightly slower than assured mode for “1 st probe failed / 2 nd probe successful” case, only because current TCH acquisition delay is slightly longer than probe retry delay Also saves PCH capacity –Assured mode (’01’) should also be included for cases where page response is absolutely needed
