26、38 39 40 41 42 43 TIA/EIA/TSB-64 ASSUMPTIONS AND ISSUES This section describes the assumptions and issues used to govern changes to IS-47-B and TSB- 57 that are required to support dual-mode CDMA CSSs (as per TIMINIS-95). Assumptions for dual-mode CDMA intersystem handoff: 1. 2. 3. 4. 5. 6 7. a. 9.

27、1 o. This document addresses intersystem analog-to-analog handoff, CDMA-to-analog handoff and CDMA-to-CDMA hard handoff. For CDMA-to-CDMA hard handoff, the CSS can be handed off to the same or to a different CDMA frequency assignment. Intersystem CDMA-to-CDMA soft handoff and analog-to-CDMA handoff

28、are for further study. The assumptions made in TSB-57 (Authentication, Signaling Message Encryption and Voice Privacy) apply to this document. Authentication related parameters that were identified in TSB-57 (Authentication, Signaling Message Encryption and Voice Privacy) are included in this docume

29、nt. CDMA uses all of the TSB-57 authentication related parameters with the exception of the VPMASK. An MSC must store the System ID (SID) of adjacent systems. The SID of the target system is passed in the IS-95Analog Handoff Direction Message that is sent from the Serving MSC to the dual-mode CDMA C

30、SS during intersystem CDMA-to-analog handoff. A CDMA system may store the location (latitude and longitude) of border Cell Sites in adjacent CDMA systems. If Mobile Assisted Handoff (MAHO) is used to select the target CDMA Cell Site) for handoff, the Serving MSC shall store the Pilot PN Sequence Off

31、set Index of each border Cell Site in adjacent CDMA systems. The Serving MSC can translate from Pilot PN Sequence Offset Index to CelllD. Ali channels transmitted from a Cell Site (on ali CDMA frequency assignments) use the same Pilot PN Sequence Offset Index. The pilot PN sequence is used by the CD

32、MA air interface to distinguish Ceii Sites. Each Cell Site uses a different shift of the same pilot PN sequence. The length of the pilot PN sequence is 215 chips. Each chip of the sequence has a duration of 813.802 ns. The Pilot PN Sequence Offset Index ranges from O to 511 and defines the actual sh

33、ifi (offset) of this sequence in units of 64 chips. The Handoff Measurement procedure is not required for MAHO because the pilot signal quality is measured by the dual-mode CDMA CSS. New intersystem handoff messages (e.g., FacilitiesDirective2) shall be used to fully support dual-mode CDMA CSSs. The

34、 new intersystem handoff messages can also be used for analog or dual-mode TDMA CSSs. For analog-to-analog handoff of dual-mode CDMA CSSs, the new intersystem handoff messages should be used when the candidateltarget system supports the new messages. For MAHO, the FacilitiesDirective2, HandoffBack2,

35、 and HandoffToThird2 INVOKE messages shall include the TargetCelllD, TargetOneWayDelay, and CDMAPilotStrength parameters for each target Cell Site that is expected to be in the new Active Set after completion of intersystem handoff. See restrictions inside the cover page. 6 EIA TSBb4 94 3234b00 0554

If MAHO is not used, the FacilitiesDirective2, HandoffBack2, and HandoffToThird2 INVOKE messages shall include th

37、e TargetCelllD, TargetOneWay Delay (if available), and CDMASignalQuality parameters for each target Cell Site designated in the HandoffMeasurementRequest2 RETURN RESULT message received from the Target MSC. The ServingCelllD parameter that is sent to candidate/target CDMA systems in intersystem hand

38、off messages, shall contain the CDMA reference Cell Site ID. The CDMA reference Cell Site is the Active Set member having the shortest signal path to the CSS. The CSS derives its time reference from this Cell Site. If other Cell Sites are in the serving systems Active Set, these Cell Site IDS shall

39、not be sent to the candidatehrget systems. The ServingOneWayDelay parameter shall be sent to the candidateharget CDMA systems in intersystem handoff INVOKE messages to provide the delay between the CSS and the Cell Site indicated by the ServingCelllD. This information is used by the candidate/target

40、 system to acquire the CSS. The CSSLocation parameter shall be sent in intersystem handoff INVOKE messages to candidate/target CDMA systems only when the CSSs location can be estimated. Multiple TargetCelllDs and associated parameters may be sent in intersystem handoff messages. This permits the dua

41、l-mode CDMA CSS to immediately have multiple Active Set members in the new serving CDMA system after completion of the intersystem handoff. The EdNo value used for the CDMASignalQuality parameter is a value used in digital communications systems as a measure of performance. The serving system measur

For a CDMA traffic channel, convert the locatio

44、n quality values to the CDMASignaiQuality parameter values. If available, include the TargetOneWayDelay parameter.
