In this step, MME sends MME configuration transmission response message according to eNB configuration transmission response message to eNB.The TNL address that comprises HeNB in the MME configuration transmission response message.Particularly, this MME configuration transmission response message is a MMEConfiguration Transfer message.Wherein, the relevant information of the source node that carries in this message is eNB ID, TAI and the TNL address of HeNB; The target node related information of carrying in this message is eNB ID and the TAI of eNB.
Carrying out above-mentioned step 202 to step 208, promptly finishing eNB and obtained the process of the TNL address of HeNB by MME and HeNB GW.Then, continue to carry out following step 209.
Step 209:eNB sends X2 interface to HeNB and sets up request message.
In this step, current access base station sends X2 interface to the target access base station and sets up request message.Because in the embodiment of the invention one, current access base station is that eNB and target access base station are HeNB, therefore, eNB sets up request message by X2 interface, sets up X2 interface to the HeNB request.Particularly, to set up request message be X2Setup Request message to this X2 interface.The content of this message can for example, can be carried the adjacent cell information of Serving cell and the Serving cell of following information: eNB according to the regulation setting of existing communication agreement in this message.
Step 210:HeNB judges that the access module of self is mixed mode, open mode or closed mode.If the access module of HeNB is mixed mode or open mode, then execution in step 211; If the access module of HeNB is a closed mode, then execution in step 221.
In this step, the HeNB as the target access base station judges the access module of self.Set up in the control procedure at once concrete base-station interface, after step 210, can only enter one of step 211 and step 221, that is,, then can not enter step 221 if enter step 211, otherwise, if enter step 221, then can not enter step 211.
Step 211:HeNB returns X2 interface to eNB and sets up response message.
In this step, the target access base station returns X2 interface to current access base station and sets up response message.Particularly, because the HeNB of mixed mode both can admit the UE that belongs to same C SG, receivability does not belong to the UE of any C S G yet, so HeNB returns X2 interface to eNB and set up response message, to confirm to set up X2 interface.X2 interface is set up closed user group (C SG) identify label (ID) and the access module information that response message comprises HeNB.HeNB sets up between response message affirmation and the eNB by this X2 interface and sets up X2 interface.Particularly, to set up response message be X2Setup Response message to X2 interface.Wherein, the C SGID of HeNB is used for the C SG under eNB indicates this HeNB; The access module information of HeNB is used for indicating this HeNB to belong to the HeNB of mixed mode or belonging to the HeNB of open mode to eNB.X2 interface is set up response message can be by improving realization to existing X2 application protocol (X2-AP), wherein a kind of concrete improved procedure is, in the service cell information cell (Served Cell Information IE) of X2-AP, interpolation is used to carry the cell of access module information.For example, this cell that is used to carry access module information can be access module cell (Access Mode IE).A kind of preferred implementation is, this cell that is used for carrying access module information is an optionally cell of X2-AP.
After this step, between eNB and HeNB, successfully set up X2 interface.In follow-up communication process, can carry out information interaction by this X2 interface between eNB and the HeNB.
Step 221:HeNB returns X2 interface to eNB and sets up failed message.
In this step, the target access base station returns X2 interface to current access base station and sets up failed message.As the HeNB of target access base station set up by this X2 interface that failed message is confirmed and eNB between can't set up X2 interface.Particularly, to set up failed message be X2Setup Failure message to X2 interface.
After this step, between eNB and HeNB, can't set up X2 interface.Then in follow-up communication process, still carry out information interaction between eNB and the HeNB by the S1 interface.
The base-station interface of the invention described above embodiment one is set up control method and has been described the process of setting up X2 interface between eNB and HeNB, access module according to HeNB is judged, if the access module of HeNB is mixed mode or open mode, then between eNB and HeNB, set up X2 interface.
The base-station interface of the following embodiment of the invention two and the embodiment of the invention three is set up control method, on the basis of the process that the invention described above embodiment one puts down in writing, after setting up X2 interface, can realize the UE handoff procedure by X2 interface.
In the embodiment of the invention two, only to set up control method and be used to realize that it is example that UE under the eNB switches to HeNB from this eNB with this base-station interface, current access base station is that eNB and target access base station are HeNB.And, in the embodiment of the invention two, with this eNB for not support that the eNB of CSG sub-district is an example.
The base-station interface of the embodiment of the invention two is set up control method and is comprised following process.
At first, carry out the process of setting up X2 interface between eNB and the HeNB.
Particularly, the process of setting up X2 interface between eNB and the HeNB can realize according to the step 201 among the invention described above embodiment one to step 221.
After this process of setting up X2 interface was finished, its execution result was one of following two kinds of situations, that is: X2 interface is set up success or X2 interface foundation failure.
Then, after the process of setting up X2 interface between eNB and HeNB was finished, when UE need switch, eNB and HeNB switched to HeNB with UE from eNB.Wherein, according to the above-mentioned execution result difference of setting up the process of X2 interface, the method for switching is also different.If the above-mentioned execution result of setting up the process of X2 interface is that X2 interface is set up successfully, when then UE need carry out the access base station switching, therefore the current X2 interface that exists between eNB and the HeNB, preferably finished above-mentioned handoff procedure by X2 interface.If being X2 interface, the above-mentioned execution result of setting up the process of X2 interface sets up failure, when then UE need carry out the access base station switching, the current X2 interface that do not exist between eNB and the HeNB, therefore, adopt the method identical, finish above-mentioned handoff procedure by the S1 interface with existing handoff procedure.
Particularly, between above-mentioned eNB and HeNB, set up in the process of X2 interface, if entered step 211 after the judgement through step 210, HeNB returns X2 interface to eNB and sets up response message, then after step 211, between eNB and HeNB, successfully set up X2 interface, then in follow-up communication process, can carry out information interaction by this X2 interface between eNB and the HeNB.Therefore, when UE need switch, eNB and HeNB switched to HeNB as non-CSG member from eNB with UE by X2 interface.When carrying out handoff procedure,, therefore when the base station of UE is switched, preferably switch by X2 interface because successfully set up X2 interface between eNB and the HeNB.In the embodiment of the invention two, this eNB is not for supporting the eNB of CSG sub-district, then the UE under this eNB is not the member of any CSG, therefore, eNB initiates the handoff procedure based on X2 interface, by based on the handoff procedure of X2 interface, this UE is switched to HeNB with non-CSG member's identity between eNB and the HeNB.
Particularly, between above-mentioned eNB and HeNB, set up in the process of X2 interface, if entered step 221 after the judgement through step 210, HeNB returns X2 interface to eNB and sets up failed message, then after step 221, between eNB and HeNB, can't set up X2 interface, then in follow-up communication process, still carry out information interaction between eNB and the HeNB by the S1 interface.Therefore, when UE need switch, eNB and HeNB switched to HeNB with UE from eNB by the S1 interface.
The base-station interface of the invention described above embodiment two is set up control method, sets up on the basis of process at the X2 interface of the invention described above embodiment one record, increases the step that the base station of UE is switched.For not support that the eNB of CSG sub-district is an example, if successfully set up X2 interface, then eNB and HeNB switch to HeNB as non-CSG member from eNB with UE by X2 interface with eNB; If do not set up X2 interface, eNB and HeNB switch to HeNB with UE from eNB by the S1 interface.
In the embodiment of the invention three, only to set up control method and be used to realize that it is example that UE under the eNB switches to HeNB from this eNB with this base-station interface, current access base station is that eNB and target access base station are HeNB.And, in the embodiment of the invention three, serve as to support that the eNB of CSG sub-district is an example with this eNB.
The base-station interface of the embodiment of the invention three is set up control method and is comprised following process.
At first, carry out the process of setting up X2 interface between eNB and the HeNB.
Particularly, the process of setting up X2 interface between eNB and the HeNB can realize according to the step 201 among the invention described above embodiment one to step 221.Wherein, send X2 interface for step 203:eNB to HeNB and set up request message.In the embodiment of the invention three, because eNB is for supporting the eNB of CSG sub-district, therefore, the X2 interface of the step 203 of the embodiment of the invention three is set up in the request message, comprise that not only the X2 interface of the invention described above embodiment one and the embodiment of the invention two sets up the content of request message, but also can comprise CSG ID and the access module information of eNB.Wherein, the CSG ID of eNB is used for the CSG under HeNB indicates this eNB; The access module information of eNB is used for indicating this eNB to belong to the eNB of mixed mode or belonging to the eNB of open mode or belong to the eNB of " shut " mode" to HeNB.
After this process of setting up X2 interface was finished, its execution result was one of following two kinds of situations, that is: X2 interface is set up success or X2 interface foundation failure.
Then, after the process of setting up X2 interface between eNB and HeNB was finished, when UE need switch, eNB and HeNB switched to HeNB with UE from eNB.Wherein, according to the above-mentioned execution result difference of setting up the process of X2 interface, the method for switching is also different.If the above-mentioned execution result of setting up the process of X2 interface is that X2 interface is set up successfully, when then UE need switch, therefore the current X2 interface that exists between eNB and the HeNB, preferably finished above-mentioned handoff procedure by X2 interface.If being X2 interface, the above-mentioned execution result of setting up the process of X2 interface sets up failure, when then UE need switch, the current X2 interface that do not exist between eNB and the HeNB, therefore, adopt the method identical, finish above-mentioned handoff procedure by the S1 interface with existing handoff procedure.
Particularly, between above-mentioned eNB and HeNB, set up in the process of X2 interface, if entered step 211 after the judgement through step 210, HeNB returns X2 interface to eNB and sets up response message, then after step 211, between eNB and HeNB, successfully set up X2 interface, then in follow-up communication process, can carry out information interaction by this X2 interface between eNB and the HeNB.Therefore, when UE need switch, eNB judged the CSG member condition of UE.If UE is not CSG member, then eNB and HeNB switch to HeNB as non-CSG member from eNB with UE by X2 interface; If UE and HeNB are the members of same CSG, then eNB and HeNB switch to HeNB as CSG member from eNB with UE by X2 interface; If UE is the member of different CSG with HeNB, then eNB and HeNB switch to HeNB with UE from eNB by the S1 interface.
By X2 interface UE is switched to the situation of HeNB from eNB as non-CSG member for eNB and HeNB:, therefore when UE is switched, preferably switch by X2 interface because successfully set up X2 interface between eNB and the HeNB.And because UE is not the member of any CSG, therefore, eNB initiates the handoff procedure based on X2 interface, by the handoff procedure based on X2 interface, this UE is switched to HeNB with non-CSG member's identity between eNB and the HeNB.
By X2 interface UE is switched to the situation of HeNB from eNB as CSG member for eNB and HeNB: in this step, because successfully set up X2 interface between eNB and the HeNB, therefore when the base station of UE is switched, preferably switch by X2 interface.And because UE and HeNB are the members in the same CSG, therefore, eNB initiates the handoff procedure based on X2 interface, by the handoff procedure based on X2 interface, this UE is switched to HeNB with CSG member's identity between eNB and the HeNB.
By the S1 interface UE is switched to the situation of HeNB from eNB for eNB and HeNB: the embodiment of the invention three, might set up successfully at X2 interface between eNB and the HeNB when but UE and HeNB are the member of different CSG, switch by the S1 interface; Also might between eNB and HeNB, set up when failing by X2 interface, switch by the S1 interface.
Wherein, X2 interface is set up successfully but UE and HeNB are under member's the situation of different CSG between eNB and HeNB: because of successfully having set up X2 interface between eNB and the HeNB, therefore when the base station of UE is switched, preferably switch by X2 interface.But because UE is the member of different CSG with HeNB, promptly UE belongs to different CSG with HeNB, therefore, even HeNB is in mixed mode or open mode, still can't compatible this UE.Therefore, eNB still initiates the handoff procedure based on the S1 interface, by the handoff procedure based on the S1 interface, this UE is switched to HeNB between eNB and the HeNB.
Set up at X2 interface between eNB and the HeNB under the situation of failure: particularly, between above-mentioned eNB and HeNB, set up in the process of X2 interface, if entered step 221 after the judgement through step 210, HeNB returns X2 interface to eNB and sets up failed message, then after step 221, between eNB and HeNB, can't set up X2 interface, therefore, in follow-up communication process, still carry out information interaction between eNB and the HeNB by the S1 interface.Therefore, when UE need switch, eNB switched to HeNB by the S1 interface with UE.
The base-station interface of the invention described above embodiment three is set up control method, sets up on the basis of process at the X2 interface of the invention described above embodiment one record, increases the step that the base station of UE is switched.With eNB is to support that the eNB of CSG sub-district is an example, and eNB judges the CSG state of UE and HeNB when switching.Do not belong to any CSG if successfully set up X2 interface and UE, then eNB and HeNB switch to HeNB as non-CSG member from eNB with UE by X2 interface; Belong to same CSG if successfully set up X2 interface and UE and HeNB, then eNB and HeNB switch to HeNB as CSG member from eNB with UE by X2 interface; Do not belong to different CSG if set up X2 interface or UE with HeNB, then eNB and HeNB switch to HeNB with UE from eNB by the S1 interface.
Fig. 3 is the structural representation of the communication system of the embodiment of the invention four.As shown in Figure 3, this communication system comprises at least: UE 31, intermediate node 32, current access base station 33 and target access base station 34.
Wherein, UE 31 is used for finding and reports new sub-district to current access base station 33.Intermediate node 32 is used to realize the interacting message between current access base station 33 and the target access base station 34, so that current access base station 33 obtains the TNL address of target access base station 34.
Current access base station 33 is used for obtaining by intermediate node 32 the TNL address of target access base station 34, and, send X2 interface to target access base station 34 and set up request message.Target access base station 34 is used to judge that the access module of self is mixed mode, open mode or closed mode.If mixed mode or open mode, target access base station 34 is used for returning X2 interface to current access base station 33 and sets up response message, and this X2 interface is set up CSG ID and the access module information that comprises target access base station 34 in the response message.If closed mode, target access base station 34 is used for returning X2 interface to current access base station 33 and sets up failed message.
On the basis of technique scheme, further, current access base station can be eNB, and at this moment, the target access base station is HeNB; Perhaps, current access base station can be HeNB, and at this moment, the target access base station is eNB.In the embodiment of the invention four, be that eNB and target access base station are that HeNB is an example only with current access base station.Above-mentioned intermediate node can be MME, also can be MME and HeNB GW, in the embodiment of the invention four, only comprises that with intermediate node MME and HeNB GW are example.Therefore obtain in the process of TNL address of target access base station 34 at current access base station 33: the eNB as current access base station 33 specifically is used for sending eNB configuration transfer request message to MME.MME specifically is used for sending MME configuration transfer request message according to eNB configuration transfer request message to HeNB GW; And the eNB configuration transmission response message according to HeNB GW transmits sends MME configuration transmission response message to eNB, comprises the TNL address of HeNB in this MME configuration transmission response message.HeNB GW is used to specifically judge that the HeNB that allows eNB and HeNB GW to control sets up X2 interface, transmits MME configuration transfer request message to HeNB; And, transmit the eNB configuration transmission response message that HeNB sends to MME.HeNB specifically is used for returning eNB configuration transmission response message to HeNB GW, comprises the TNL address of HeNB in this eNB configuration transmission response message.
On the basis of technique scheme, further, if current access base station 33 is not for supporting the base station of CSG sub-district, then current access base station 33 also is used for switching to target access base station 34 as non-CSG member from current access base station 33 by intermediate node with target access base station 34.
On the basis of technique scheme, further, if current access base station 33 is for supporting the base station of CSG sub-district, then current access base station 33 specifically is used for sending to target access base station 34 and comprises that the CSG ID of current access base station 33 and the X2 interface of access module information set up request message.And if current access base station 33 is the base station of support CSG sub-district, then current access base station 33 can adopt two kinds of concrete modes to realize switching with target access base station 34.Wherein, mode one: identical for the situation of the base station of not supporting the CSG sub-district with current access base station 33, current access base station 33 switches to target access base station 34 as non-CSG member from current access base station 33 by intermediate node with target access base station 34.Mode two: because current access base station 33 is the base station of support CSG sub-district, therefore current access base station 33 can also be used to judge the CSG member condition of UE 31.And current access base station 33 also is used for when UE 31 is not C SG member with target access base station 34, by X2 interface UE 31 is switched to target access base station 34 as non-CSG member from current access base station 33.Current access base station 33 also is used for by X2 interface UE 31 being switched to target access base station 34 as CSG member from current access base station 33 when UE 31 is the member of same CSG with target access base station 34 with target access base station 34.Current access base station 33 also is used for by the S1 interface UE 31 being switched to target access base station 34 from current access base station 33 when UE 31 is the member of different CSG with target access base station 34 with target access base station 34.
By above-mentioned embodiment as seen, the base-station interface that the present invention proposes is set up control method, receives after X2 interface that current access node sends sets up request message at the target access node, and the target access node is judged self access module.When the target access node is mixed mode or open mode, between current access node and target access node, set up X2 interface; When the target access node is closed mode, between current access node and target access node, do not set up X2 interface.When the base station of UE is switched, preferably switch by X2 interface.Because the signaling of X2 interface needn't be carried out transfer by core net, therefore reduced the signaling traffic of core net, reduced the load of core net.
For example, the base-station interface that the present invention is proposed is set up control method and is applied to a large scale business square.A lot of HeNB have been disposed on this large scale business square.These HeNB can be mixed modes, and under mixed mode, this HeNB is the also non-CSG member of receivability of receivability CSG member both.Concerning UE, if this UE and HeNB are the members of same CSG, then the base-station interface that proposes according to the present invention is set up control method, and this UE can insert the CSG part of this HeNB by X2 interface; If this UE is not the member of CSG, then the base-station interface that proposes according to the present invention is set up control method, and this UE can insert the non-CSG part of this HeNB by X2 interface.If the HeNB that disposes is an open mode, then there is not above-mentioned access restriction more, this UE can insert this HeNB by X2 interface.Thereby in these cases, carry out the switching of base station,, therefore can reduce the signaling traffic load of core net because the X2 interface signaling is not carried out transfer by core net by X2 interface.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being made, is equal to replacement, improvement etc., all should be included within the scope of protection of the invention.
