Step 1, monitoring objective signaling;
Described target signaling is the RANAP signaling that meets the following conditions simultaneously: with switch relevant, from the target Femto base station of base station, indicated handover operation under this Femto gateway.
The Femto gateway is handled switching relevant signaling, at first will find out signaling to be processed from the process signaling of this gateway, i.e. the target signaling.The target signaling is to satisfy the RANAP signaling of above-mentioned three conditions, if the signaling that monitors is not the target signaling, then still according to prior art this signaling is carried out respective handling; If the Femto gateway detects the target signaling, then it is handled according to the 3GPP agreement, therefrom extract crucial cell, form next signaling, and mail to corresponding Femto base station.Like this, the target signaling just needn't needn't be handled by core net by transparent transmission to core net, but has just obtained processing under this Femto gateway.
Embodiment two
Two steps of embodiment one can realize by following step, as shown in Figure 4.
Step 1 specifically may further comprise the steps:
Step 11, monitoring RANAP signaling;
Step 12, the RANAP signaling that monitors is decoded;
Step 13, judge the signaling type of RANAP signaling according to the Message Type cell of decoded RANAP signaling;
Step 14, judge that according to the signaling type of RANAP signaling whether the RANAP signaling is and switches relevant signaling, if not, then the RANAP signaling is carried out corresponding operating, if the signaling relevant with switching then enters step 15;
Step 15, judge that according to the signaling type of RANAP signaling the RANAP signaling is from core net or from the base station, if from core net transparent transmission RANAP signaling then, if then enter step 16 from the base station;
Step 16, judge the handover operation that the RANAP signaling is indicated according to the related cells in the RANAP signaling target Femto base station whether under this Femto gateway, if not transparent transmission RANAP signaling then, if then change following step 17 over to.
