Paging message is directly sent to the Home eNodeB of UE access, avoid paging message is sent to recorded in paging message with
The corresponding base station of track area list, to be effectively reduced network burden.
As described above, there are certain situation, UE can not receive paging message, to also make sound to paging message
It answers.If core net does not receive the page response of UE, carries out second and page.At this point, according to recording in paging message
Paging message is sent to the corresponding base station of tracking area list, and in a broadcast manner sends paging message by tracking area list
To corresponding base station.
In this step, contacting for tracking area and corresponding Home eNodeB is established by Home eNodeB unique mark.Specifically
Say, when Home eNodeB is established S1 with femto gateway (HeNB GW) and is connect, HeNB GW record Home eNodeB unique marks with
Then paging message is broadcast to the corresponding Home eNodeB of tracking area by the correspondence of tracking area according to the corresponding relationship.This
The specific implementation flow of step is as follows：
Home eNodeB establishes SCTP (Stream Control Transmission with the signaling convergence module in HeNB GW
Protocol, Flow Control Transmission Protocol) connection, and S1-SETUP signalings are sent to signaling convergence module, the S1-SETUP
Signaling carries the tracking area of base station unique mark and base station service, at this point, signaling convergence module record SCTP couplings number, base station
The correspondence of unique mark and tracking area.HeNB GW can get the tracking area of all Home eNodeB services.
This step sends the paging message for the transmission that fails in once paging, is had again by secondary paging
