CHAPTER 4. Message Flow

4.1 Call Processing Message Flow

4.1.1 Initial Access

The following is the procedure to set the Provisioned Service Flow (SF) of the network-

initiated Dynamic Service Add (DSA) mode in the process of the initial network entry.

An MS periodically receives Downlink Channel Descriptor (DCD), Downlink-MAP (DL-

MAP), Uplink Channel Descriptor (UCD) and Uplink-MAP (UL-MAP) messages from the

RAS in the initial access, acquires the downlink channel synchronization and the uplink

parameter and sets the Provisioned SF connection. The NWG standard defines PMIP and

CMIP to support Mobile IP and the procedure below takes account of both PMIP and CMIP.

But, ACR supports PMIP only.
