至此,MS/AT切换到CDMA2000并保留在休眠态,MS/AT在HRPD 系统中的A10连接被释放,取而代之的是CDMA2000系统中的A10连接。 At this point, MS / AT is switched to the CDMA2000 and remains in the sleep state, MS / AT in an HRPD system is A10 connection is released, it replaced A10 connection in a CDMA2000 system.

图2的流程也不适用于HRPD休眠态语音呼叫时从HRPD到CDMA2000 的切换。 2 is a flow chart does not apply to the sleep state HRPD to CDMA2000 HRPD speech switch from the call.

对于HRPD休眠态语音呼叫,MS/AT应在CDMA2000系统中建立语音业务,并将HRPD的休眠态数据业务切换到CDMA2000。 HRPD dormant for a voice call, MS / AT should establish a voice service in a CDMA2000 system, the HRPD dormant state and switch data traffic to CDMA2000. 若MS/AT不将HRPD的休眠态数据业务切换到CDMA2000,在遞话过程中PDSN有下行数据发给MS/AT, MS/AT无法接收来自HRPD系统的下行数据。 If the MS / AT in the dormant state does not HRPD data service handover to CDMA2000, if the delivery process PDSN downlink data to the MS / AT, MS / AT can not receive the downlink data from the HRPD system.

可见,现有技术的流程都不适用于HRPD休眠态语音呼叫时MS/AT从HRPD到CDMA2000的切换。 Be seen, the prior art processes do not apply to the sleep state HRPD voice MS / AT to switch from the CDMA2000 HRPD call.
