In the scheme of the present embodiment, it can be led to by the X2 interface of itself between the first eNodeB and the 2nd eNodeB
Letter is the chain of command agreement schematic diagram of X2 interface protocol stack as shown in Fig. 4 (a).Due in the X2 interface agreement of standard, and
The specification for not customizing transmission AP nodal informations (i.e. with the relevant nodal informations of WLAN), therefore, in the scheme of the present embodiment one
In, the first eNodeB, can be by the node of the first AP when sending the nodal information of the first AP to the 2nd eNodeB by X2 interface
Information carries in based on data packet caused by X2 agreements, specifically, is carried in the X2-AP layers of data packet.In certain versions
Top layer can be X2-U layers in this X2 protocol stacks, and as shown in Fig. 4 (b), in the case, the first eNodeB can be by the first AP
Nodal information carry and in the X2-U of data packet and send.
Be transmitted by X2 interface between eNodeB in the present embodiment one be the present embodiment alternative, the present embodiment
It is not limited to through other known interfaces between eNodeB or newly-increased interface come transmission node information.
Step 103：2nd eNodeB receives the nodal information of the first AP.

The nodal information of AP, specifically, if in a step 102, the first eNodeB carries the nodal information of the first AP at X2-AP layers
In, then after the 2nd eNodeB receives the data packet from the first eNodeB by X2 interface, first can be read from X2-AP layers
The nodal information of AP.
Through this embodiment in one step 101~step 103 scheme, the nodal information of the first AP pass through co-sited first
ENodeB is sent to indirectly at the 2nd eNodeB of not co-sited, realizes AP and the nodal information of itself is sent to not co-sited
Purpose at eNodeB.
Step 104：The nodal information of the first AP received is sent to the 2nd AP with itself co-sited by the 2nd eNodeB.
This step 104 can lead to using between the AP and eNodeB of co-sited again on the basis of step 101 to step 103
The ability for crossing privately owned interface communication, by the forwarding of the 2nd eNodeB, by the nodal information with incoherent first AP of the 2nd AP
It has been sent at the 2nd AP, has realized the transmission of nodal information between AP indirectly, the utilization rate of radio resource can be effectively improved.
More preferably, the 2nd eNodeB that the first eNodeB selections receive the first AP nodal informations can have following three kinds of scenes：
Scene one：Defined in the configuration file of the first eNodeB：When the first eNodeB receives the node letter of the first AP
After breath, which is sent to other eNodeBs adjacent with the first eNodeB so that in a step 102, if first
ENodeB is not received by the mark of other eNodeB when receiving nodal information, then can be according to the instruction of configuration file, will
The nodal information of first AP is sent to other eNodeBs adjacent with itself, and (other eNodeB here can be considered second
eNodeB)。
Scene two：First AP can be determined to need to receive before sending the nodal information of itself to the first eNodeB
The mark of the eNodeB of the nodal information, and the mark of eNodeB is sent to the first eNodeB, it is desirable that the first eNodeB will be saved
Point information is sent to corresponding 2nd eNodeB of mark.In order in a step 102, if the first eNodeB is receiving node letter
The mark of other eNodeB is also received while breath, then is sent to the nodal information of the first AP according to mark corresponding
eNodeB。
For example, when the terminal of the first AP of access removes the coverage area of the first AP, and move into the first AP not co-sited the
After the coverage area of two eNodeB, the position switching of terminal need to be carried out, terminal will be on the first AP (source node that position switches)
The mark for reporting the 2nd eNodeB (destination node of position switching) currently moved into, at this point, the first AP can believe the node of itself
The mark of breath and the 2nd eNodeB are sent to the first eNodeB of co-sited, then in a step 102, the first eNodeB is according to second
The nodal information of first AP is sent to the 2nd eNodeB by the mark of eNodeB so that the 2nd eNodeB is knowing terminal immigration
After preceding accessed node, the position handoff procedure of terminal can be correctly completed.
Scene three：First AP can be determined to need to receive before sending the nodal information of itself to the first eNodeB
The mark of 2nd AP of the nodal information, and looked into from upper layer network element (such as wireless controller (Access Controller, AC))
The mark with the 2nd eNodeB of the 2nd AP co-sited is ask out, and the mark of the 2nd eNodeB is sent to the first eNodeB, it is desirable that
Nodal information is sent to corresponding 2nd eNodeB of mark by the first eNodeB.In order in a step 102, if the first eNodeB
The mark of the 2nd eNodeB is also received while receiving nodal information, then is sent out the nodal information of the first AP according to mark
Give the 2nd eNodeB.
For example, when the terminal of the first AP of access removes the coverage area of the first AP, and move into the coverage area with the 2nd AP
Afterwards, the position switching of terminal need to be carried out, terminal will report the 2nd AP currently moved into the first AP (source node that position switches)
The mark of (destination node of position switching), identifies at this point, the first AP can be inquired to AC with the 2nd eNodeB of the 2nd AP co-sited,
And be sent to the first eNodeB, then in a step 102, the first eNodeB is according to the mark of the 2nd eNodeB, by the section of the first AP
Point information is sent to the 2nd eNodeB so that the 2nd eNodeB is receiving the nodal information of the first AP and knowing that terminal needs to access
When two AP, the nodal information of the first AP can be sent to the 2nd AP of co-sited, the position that terminal is correctly completed by the 2nd AP is cut
Change process.
The scheme of the embodiment of the present invention one, which is accomplished that from AP to the eNodeB of not co-sited, sends the nodal information of itself
Process, due to the communication process between two equipment should be it is mutual, the scheme of the embodiment of the present invention two additionally provides
The process of own node information is sent from eNodeB to the AP of not co-sited.
Embodiment two：
As shown in figure 5, being eNodeB in the embodiment of the present invention two to the signaling process of the AP sending node information of not co-sited
Schematic diagram, the method mainly include the following steps that：
Step 201：First eNodeB sends the nodal information of itself to the 2nd eNodeB.
In this step 201, the first eNodeB can be sent out in the way of step 102 in embodiment one to the 2nd eNodeB
Give the nodal information of itself.
Step 202：The nodal information of the first eNodeB received is sent to itself co-sited by the 2nd eNodeB
Two AP.
In this step 202, the 2nd eNodeB can obtain the first eNodeB in the way of step 103 in embodiment one
The nodal information of transmission, and the privately owned interface between the 2nd AP for passing through co-sited send the nodal information of the first eNodeB
To the 2nd AP.
More preferably, the 2nd AP that the first eNodeB selections receive itself nodal information can have following two kinds of scenes：
Scene one：
The nodal information of itself is sent to each adjacent eNodeB by the first eNodeB, and (adjacent eNodeB can be considered here
2nd eNodeB), it is desirable that the nodal information of the first eNodeB is sent to the AP of respective co-sited by adjacent eNodeB.
Scene two：First eNodeB determines to need to receive before sending the nodal information of itself to the 2nd eNodeB
The mark of the AP of the nodal information, and inquire at upper layer network element (such as operation maintenance center (OMC)) corresponding with the mark
2nd eNodeB of AP co-sited, and the node identification of itself is sent to the 2nd eNodeB.In order in step 202, second
The nodal information of first eNodeB can be sent to the 2nd AP of co-sited by eNodeB.
For example, when the terminal of the first eNodeB of access removes the coverage area of the first eNodeB, and move into and first
ENodeB after the coverage area of the 2nd AP of co-sited, need to not carry out the position switching of terminal, terminal will be to the first (positions eNodeB
The source node of switching) report the mark of the 2nd AP destination node of switching (position) currently moved into, at this point, the first eNodeB from
It is inquired in upper layer network element with after the 2nd eNodeB of the 2nd AP co-sited, the nodal information of itself is sent to the 2nd eNodeB,
So that after the nodal information of the first eNodeB is sent to the 2nd AP by the 2nd eNodeB, the 2nd AP would know that be connect before terminal moves into
The node entered, and it is correctly completed the position handoff procedure of terminal.
Other than terminal reports the mark of the 2nd AP to the first eNodeB, if the first eNodeB first passes through embodiment one in advance
Mode know that the coverage area information of the 2nd AP, the then measurement report that the first eNodeB can be reported according to terminal determine that terminal is
The no coverage area for moving into the 2nd AP can be inquired when determining that terminal moves into the coverage area of the 2nd AP from upper layer network element
With the 2nd eNodeB of the 2nd AP co-sited.
Two scheme through this embodiment, the first eNodeB is by the transmittability between eNodeB, by the node of itself
Information is transmitted to the 2nd eNodeB, then by the 2nd eNodeB using the transmittability between the 2nd AP of co-sited, by first
The nodal information of eNodeB is sent at the 2nd AP, realizes the AP that the nodal information of itself is sent to not co-sited by eNodeB
Place.When the scheme of the scheme of the present embodiment two and embodiment one is combined together, it can be achieved that the eNodeB and AP of non-co-sited it
The interaction of intermediate node information reaches interoperability truly.
The present embodiment one and embodiment two realize that the interactive process of nodal information does not include between the eNodeB and AP of co-sited
But it is not limited to apply in following scene：
