When the mapping of eNodeB ID to RNC ID, a LAC can be chosen out of this preset LAC to construct RNC ID, this
When, in the RNC ID other codes all can be now net code.
RNC ID after mapping in the present embodiment be the RNC ID that existing net is not present, can to avoid after mapping RNC ID with
Now the RNC ID in net repeats that RIM message mistake is caused to transmit.
404: target SGSN sends Direct Information Transfer message to BSC or RNC, takes in the message
With above-mentioned RNC ID as source address；
Wherein, target SGSN can according to the RIM routing address in the RAN Information Relay message received,
From dns lookup to corresponding BSC or RNC.
After 405:BSC or RNC receives the Direct Information Transfer message, returns and carry Target cell
System information Direct Information Transfer message give the SGSN, wherein the message also carries above-mentioned
The address as a purpose RNC ID；
406: the SGSN Direct Information Transfer for receiving the system information for carrying Target cell disappears
After breath, according to the above-mentioned mapping relations saved, the RNC ID in the message is replaced with into corresponding eNodeB ID, sends packet
Message containing the eNodeB ID is to MME；
Wherein, SGSN can obtain RIM routing letter in the Direct Information Transfer message received
Breath, extracts the RAI information in the RIM routing iinformation, obtains corresponding MME in DNS query according to the RAI information.
The Direct Information Transfer that 407:MME receives the system information of above-mentioned carrying Target cell disappears
After breath, the system information of the Target cell is sent to the corresponding eNodeB of the eNodeB ID.
The above method provided in this embodiment receives RIM request message by SGSN, by eNodeB identity map therein
