NIST Scan 流程

1. SSscheduler::pause_scanning ()
2. Mac::send_scan_result (void *res, int size)
3. MIHAgent::process_scan_response (Mac *mac, void *rsp, int size)
3.1 MIHScan::process_scan_response (int macAddr, void *rsp, int size)
4. Handover1::process_scan_conf (struct mih_scan_rsp *rsp)

NIST Handover 重要function

Define old link(ss & old BS) and new link(ss & new BS)
void Mac::send_link_handover_imminent (int macTerminal, int oldPoA, int macPoA){ if (mih_ && ((subscribedEventList_ >> MIH_LINK_HANDOVER_IMMINENT)& 0x1) ) {
link_handover_imminent_t *e = (link_handover_imminent_t*) malloc (sizeof (link_handover_imminent_t)); e->linkIdentifier.type = linkType_; e->linkIdentifier.macMobileTerminal = macTerminal; e->linkIdentifier.macPoA = oldPoA; e->newLinkIdentifier.type = linkType_; e->newLinkIdentifier.macMobileTerminal = macTerminal; e->newLinkIdentifier.macPoA = macPoA; e->macOldAccessRouter = oldPoA; e->macNewAccessRouter = macPoA; mih_->recv_event (MIH_LINK_HANDOVER_IMMINENT, e); } //else we don't need to do anything}
