  1. BSPM & F-QPCH IssuesChair, SWG231/13/04

  2. Related Ballot Comments • LU-TC-15, QC-TC-107 (BSPM Periodicity) • MOT-TC-12, LU-TC-10 (How long to wait for BSPM) • QC-TC-74, VIA-TC-1 (QPCH usage for BCMCS) • QC-TC-89 (BCMCS_FLOW_ID based paging) • QC-TC-154 (BSPM_SEQ_NUM in another msg)

  3. Services Types • Type 1 Services • “TV channel” like programs • Set of flows in a given sector not expected to change very frequently • Every couple of hours, days, weeks? • When users wants to watch BCMCS flow X, MS will look for BCMC info to determine where/how to watch BCMCS flow X • Think of it as MS originated BCMC • Type 2 Services • Group calls, etc. • Set of flows in a given sector expected to change very frequently • Every few seconds, few minutes? • When BCMCS flow X is added, idle mobiles need to be notified so they can decide to monitor • Think of it as MS terminated BCMC

  4. Rev D Support for Type 1 Services • BSPM is the right message • Periodicity for BSPM needs to be defined to help mobiles • LU-TC-15, QC-TC-107 • Need to define how long MS should wait to receive BSPM once woken up at slot per defined period • MOT-TC-12, LU-TC-10 • No need to notify idle mobiles when BCMCS flows added/removed from BSPM • F-QPCH support not needed • Differential BSPM not critical • Needed only to update mobiles currently watching BCMCS

  5. Rev D Support for Type 2 Services • Currently Differential BSPM being used for Type 2 service • Differential BSPM is essentially a group page mechanism • Differential BSPM needs to be sent more frequently than BSPM periodicity chosen for Type 1 Service due to latency requirements • F-QPCH support very useful • F-QPCH used to notify idle mobiles about differential BSPM being transmitted • Is differential BSPM the right approach for Type 2 services? • Alternatives: • Group Page on F-CCCH • New message on F-BCCH • Is current F-QPCH BI indicator the correct approach? • Alternatives: • BCMC tri-state on mobiles PI indicator (VIA-TC-1) • BCMCS_FLOW_ID hashed F-QPCH slots with BI indicators • BCMCS_FLOW_ID hashed F-QPCH slots with BCMCS_FLOW_ID hashed PI indicators
