31、of Parameter Value Assignments for cdma2000 Spread Spectrum Standards 3 1.4 Overview of Broadcast/Multicast Service 4 Each Broadcast/Multicast flow is identified by a BCMCS_FLOW_ID, which is used to 5 specify a flow between the BCMCS, BCMCSCF (see 2), and Layer 3 Signaling (see Figure 6 1). See 5 fo
32、r detailed descriptions. 7 The BCMCS initiates the service by requesting the BCMCSCF to send a request to Layer 8 3 Signaling to monitor a specific BCMCS flow. Layer 3 Signaling then performs all the 9 necessary air-interface procedures (e.g., search for a frequency carrying the requested 10 BCMCS f
33、low) to obtain the bearer data of the flow and deliver the data to the BCMCS. 11 The BCMCS terminates the service by requesting the BCMCSCF to send a request to 12 Layer 3 Signaling to stop monitoring a specific BCMCS flow. Layer 3 Signaling then 13 performs all the necessary air-interface procedure
34、s to stop delivering the bearer data to 14 the BCMCS. Layer 3 Signaling will also release any air-interface resources (e.g., a 15 dedicated traffic channel) associated with the flow. 16 TIA 1101 1-3 Layer 3 SignalingBCMCSBCMCSBCMCFLOW2Mobile StationBCMCFLOW1BCMCFLOWn.BCMCFLOW2BCMCFLOW1BCMCFLOWn.BMAC

49、 packets 24 received from the BMAC (see 4) and perform the procedures in accordance with 25 3.2 for the packets received before delivering to the BCMCS. 26 If the BCMCSCF receives the BCMC-Monitor.Response (BCMCS_FLOW_ID, result, cause, 27 reason_ind) from Layer 3 Signaling with result equal to “FAILURE”, the BCMCSCF shall 28 perform the following: 29 Relay the response to BCMCS. 30 If the BCMCSCF receives an indication to stop monitor the BCMCS flow, the BCMCSCF 31 shall perform the following: 32 Send the BCMC-Stop-Monitor.Request (BCMCS_FLOW_ID)
