Figure 23: LOAD-QUERY Call Flow
1
CBC sends LOAD-QUERY message to HNB-GW.

HNB-GW forwards the LOAD-QUERY enquiry message to corresponding HNBs in SERVICE AREA
LIST provided in the message.

Collision Case:
a
At a Time, ASR5x00 allows One Load query for a particular service area. If one LOAD QUERY is
in process then in that time frame other load queries are dropped for those service areas.
b
If TCP connection is down then the response to be sent to CBC can be dropped. RESET message from
CBC takes care of such situation. Other collisions are either taken care by HNB or by SABP timeout.
