Abstract
Call setup latency for a packet data call dormant reactivation is reduced by bypassing service negotiation and/or RLP Sync exchange procedures using values stored at the BSC. Previously negotiated parameters may be used to bypass service negotiation. A non-zero RTT value, calculated by a previously performed RLP Sync exchange, is stored at the BSC, and transmitted to the MS upon dormant reactivation. The MS uses the RTT to calculate a RLP REXMIT_TIMER value, bypassing a RLP Sync exchange with the BSC. The service configuration parameters and non-zero RTT may be stored at the BSC in the RLP BLOB of a SCR, which may be transmitted to the MS in an SCM. The SCR may store multiple records, each containing negotiated service configuration parameters and/or a non-zero RTT associated with a service instance, selected by a SRID transmitted by the MS.
