Embodiment
Hereinafter will describe the present invention with reference to the accompanying drawings and in conjunction with the embodiments in detail.Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.
Fig. 1 is that this method comprises according to the flow chart of the pre-established method of the R4 data channel of the embodiment of the invention:
Step S102, relaying ASN-GW receive the pre-established request of data channel from the candidate target BS under the relaying ASN-GW for the first time;
Step S104, in response to the pre-established request of this data channel, relaying ASN-GW finish and grappling ASN-GW between R4 data channel pre-established;
Step S106, relaying ASN-GW receive the pre-established request of data channel from the candidate target BS under the relaying ASN-GW once more, cancellation carry out according to the pre-established request of data channel that receives once more and grappling ASN-GW between R4 data channel pre-established.
The R4 mouth of correlation technique is striden in the pre-established flow process of data channel of ASN-GW switching, do not carry out sharing of R4 data channel, promptly when the candidate's of a plurality of Relay ASN-GW management target BS is initiated the pre-established request of data channel, Relay ASN-GW is with the pre-established flow process that will carry out R4 data channel repeatedly between the grappling ASN-GW, and this can cause the Signalling exchange of R4 mouth too loaded down with trivial details.The inventor finds that it is necessary finishing the pre-established of R6 data channel with a plurality of candidates' target BS, and still same Relay ASN-GW is unnecessary with the repeatedly pre-established process of the R4 data channel of grappling ASN-GW.Therefore, in this method, when the R4 switching takes place when, when Relay ASN-GW receives the pre-established request of candidate's the data channel of target BS, finish the pre-established process with the R4 data channel of grappling ASN-GW, Relay ASN-GW no longer repeated to finish the pre-established process of R4 data channel with grappling ASN-GW when the candidate target BS of this Relay ASN-GW management afterwards sent the pre-established request of data channel.So just can avoid the pre-established unnecessary flow process of bringing that repeats of R4 data channel to repeat, simultaneously because sharing of the pre-established data channel of R4 still can guarantee the effect of pre-established data channel in switching the continuity demand.This method has been simplified the Signalling exchange of R4 mouth, thereby has reduced handover delay, has optimized the performance of handoffs of striding ASN-GW.
In the correlation technique, in the execution phase of switching, grappling ASN-GW also will finish the deletion flow process of pre-established data channel repeatedly with RelayASN-GW, this has also caused the waste of R4 message order, handle more complicated, for this reason, adopt following mode to carry out the deletion of data channel in the present embodiment:
(1) be under the situation of the candidate target BS under the relaying ASN-GW in the chosen target BS of switching, relaying ASN-GW only delete and relaying ASN-GW under all not chosen candidate target BS between pre-established R6 data channel, and keep pre-established R4 data channel.
In the correlation technique,, need delete each self-corresponding R4 data channel respectively,,, then need not to delete, further reduce handling process because it is occupied to share the R4 data channel by this mode for not chosen candidate target BS.
(2) be under the situation of the candidate target BS under the grappling ASN-GW in the chosen target BS of switching, the chosen target BS that relaying ASN-GW determine to switch for the candidate target BS under the grappling ASN-GW after, pre-established R6 data channel between all candidate target BS under deletion and the relaying ASN-GW, and delete pre-established R4 data channel.
In the correlation technique, because the candidate target BS under all relaying ASN-GW is all not chosen, therefore, the pre-established R4 data channel that needs the candidate target BS correspondence under all relaying ASN-GW of deletion, but by this mode, because the R4 data channel then only need once be deleted for sharing, and has further reduced handling process.
Need to prove, can determine in several ways whether relaying ASN-GW is to receive from the pre-established request of the data channel of the candidate target base station BS under the relaying ASN-GW for the first time, for example, relaying ASN-GW can determine whether relaying ASN-GW is to receive from the pre-established request of the data channel of the candidate target base station BS under the relaying ASN-GW for the first time by whether there being pre-established R4 data channel between judgement and the grappling ASN-GW.This mode is simple, is easy to realize.
Preferably, cancellation carry out according to the pre-established request of data channel that receives once more and grappling ASN-GW between the pre-established of R4 data channel comprise: when the pre-established request of data channel that receives was once more responded, relaying ASN-GW cancellation sent the pre-established request of R4 data channel to grappling ASN-GW.
Further, when the pre-established request of data channel that receives was once more responded, relaying ASN-GW was directly to the pre-established response of candidate target BS return data passage that sends the pre-established request of data channel that receives once more.
Fig. 2 is the structured flowchart according to the relaying ASN-GW of the embodiment of the invention, and this relaying ASN-GW comprises: receiver module 22 is used to receive the pre-established request of data channel from the candidate target BS under the relaying ASN-GW; Pre-established module 24 is used under receiver module 22 receives situation from the pre-established request of data channel of the candidate target BS under the relaying ASN-GW for the first time, finish and grappling ASN-GW between R4 data channel pre-established; Under receiver module 22 receives situation from the pre-established request of data channel of the candidate target BS under the relaying ASN-GW once more, cancellation carry out according to the pre-established request of data channel that receives once more and grappling ASN-GW between R4 data channel pre-established.
Fig. 3 is the preferred structure block diagram one according to the relaying ASN-GW of the embodiment of the invention, as shown in Figure 3, this relaying ASN-GW also comprises: first removing module 32, being used in the chosen target BS of switching is under the situation of the candidate target BS under the relaying ASN-GW, under the prerequisite that keeps pre-established R4 data channel, the pre-established R6 data channel between all the not chosen candidate target BS under deletion and the relaying ASN-GW only.
Fig. 4 is the preferred structure block diagram two according to the relaying ASN-GW of the embodiment of the invention, and as shown in Figure 4, this relaying ASN-GW also comprises: determination module 42 is used for determining that the chosen target BS of switching is the candidate target BS under the grappling ASN-GW; Second removing module 44, being used in the chosen target BS of switching is under the situation of the candidate target BS under the grappling ASN-GW, pre-established R6 data channel between all candidate target BS under deletion and the relaying ASN-GW, and delete pre-established R4 data channel.
Preferably, whether pre-established module 24 is used for by existing pre-established R4 data channel to determine whether receiver module 22 is to receive from the pre-established request of the data channel of the candidate target base station BS under the relaying ASN-GW for the first time between judgement and the grappling ASN-GW.
The embodiment 1-3 that describes below combines the technical scheme of above-mentioned a plurality of preferred embodiments.
Embodiment 1
The pre-established method that adopts above R4 data channel of this embodiment describing in detail realizes sharing the R4 data channel, thereby strides the method for the R4 mouth switching of Wimax ASN-GW.The pre-established method of R4 data channel comprises:
Pre-established stage candidate's target BS is when finishing the foundation of data channel between the Relay ASN-GW, if Relay ASN-GW does not finish pre-established with the R4 data channel of grappling ASN-GW, need trigger the flow process of setting up by Relay ASN-GW so with the R4 data channel of grappling ASN-GW.If when also having candidate's target BS to initiate data channel pre-established afterwards, Relay ASN-GW perceives ASN-GW with grappling and has finished after R4 data channel pre-established, has just no longer initiated with the pre-established flow process of the data channel of grappling ASN-GW.
Be divided into two kinds of different scenes in the R4 mouth of striding ASN-GW switches, be respectively: the target BS that (1) is selected is under Relay ASN-GW management, and detailed process will be described in embodiment 2; (2) Xuan Ding target BS is under grappling ASN-GW management, and detailed process will be described in embodiment 3.
Perceive selected target BS under its management at the execution phase Relay ASN-GW that switches, will trigger the flow process of setting up of R4 data channel, and initiation is with the deletion flow process of the pre-established data channel of the unchecked candidate target BS of its management.The ASN-GW of grappling simultaneously perceives the foundation of having finished the R4 data channel with Relay ASN-GW, and promptly Xuan Ding target BS triggers the deletion flow process with the data channel of source BS so under Relay ASN-GW management.If selected target BS is under grappling ASN-GW management, grappling ASN-GW will trigger with the release of the BS of source and with the release of the R4 data channel of RelayASN-GW so, it is chosen that the deletion that in a single day Relay ASN-GW perceives the pre-established data channel of R4 means that the BS of its management does not have, and then initiates the release flow process with the pre-established data channel of the BS of all its management.
Embodiment 2
Fig. 5 is according to the selected BS of the embodiment 2 R4 mouth switching flow figure in Relay ASN-GW side, and as shown in Figure 5, selected BS is as follows at the R4 mouth switching flow of Relay ASN-GW side:
Step 1: target BS comes the pre-established of trigger data passage for Relay ASN-GW by sending Path_PreReg_Req (the pre-established request of passage) message, wherein carry data channel information, and set TPath_PreReg_Reql timer (the pre-established request timer of passage).
After Relay ASN-GW receives the pre-established request of data channel, do not carry out the pre-established of R4 data channel by the Anchor ASN-GW ID judgement that message is carried with this grappling ASN-GW, trigger the pre-established flow process of R4 data channel by transmission Path_PreReg_Req request, and set TPath_PreReg_Req1 timer (the pre-established request timer 1 of passage).
Step 2: reply Path_PreReg_Rsp (the pre-established response of passage) message after the grappling ASN-GW request of receiving and give Relay ASN-GW and stop the TPath_PreReg_Req1 timer, set TPath_PreReg_Rsp1 timer (the pre-established response timer 1 of passage).
After Relay ASN-GW receives the answer of grappling ASN-GW, reply Path_PreReg_Rsp message and give target BS, and set TPath_PreReg_Rsp2 timer (the pre-established response timer 2 of passage).After target BS is received answer, stop the TPath_PreReg_Req1 timer.
Step 3: target BS sends Path_PreReg_Ack (the pre-established affirmation of passage) message and gives Relay ASN-GW, and Relay ASN-GW stops the TPath_PreReg_Rsp1 timer after receiving message.
Relay ASN-GW sends Path_PreReg_Ack message to grappling ASN-GW, but after receiving message, grappling ASN-GW stops the TPath_PreReg_Rsp2 timer.
Step 4: this moment, target BS 2 was finished R6 with grappling ASN-GW, the pre-established flow process of R4 data channel, target BS 1 also will be initiated the pre-established flow process of data channel simultaneously, same target BS 1 sends Path_PreReg_Req asks the ASN-GW to Relay, when Relay ASN-GW receives this request, judge and to have finished pre-established with grappling ASN-GW R4 mouth data channel, then directly reply target BS 1 Path_PreReg_Rsp message, and establish timer TPath_PreReg_Rsp2 and wait for Path_PreReg_Ack message.
Step 5: target BS 1 stops timer TPath_PreReg_Req1 after receiving and replying message, and sends Path_PreReg_Ack message to RelayASN-GW.So far finished the pre-established flow process of target BS 1 with the R6 data channel of Relay ASN-GW.
Step 6: handover execution stage, selected target BS 2 sends Path_Reg_Req (passage is set up request) and gives Relay ASN-GW, the flow process of setting up with the R4 data channel of the ASN-GW of grappling is not also finished in Relay ASN-GW discovery, send Path_Reg_Req so and ask, and timer TPath_Reg_Req2 (passage is set up the request timer 2) is set to grappling ASN-GW.
Step 7: after grappling ASN-GW receives request message, reply Path_Reg_Rsp (passage is set up response), Relay ASN-GW stops timer TPath_Reg_Req1 after receiving answer, and transmit this message and give target BS 2, target BS 2 stops waiting timer TPath_Reg_Req2 after receiving answer.
Step 8: target BS 2 is replied Path_Reg_Ack message and is given Relay ASN-GW, Relay ASN-GW stops waiting timer TPath_Reg_Rsp1 (passage is set up response timer 1), and transmitting Path_Reg_Ack (passage is set up and confirmed) to grappling ASN-GW, grappling ASN-GW stops to wait for TPath_Reg_Ack2 timer (passage is set up and confirmed timer 2) after receiving message.So far Xuan Ding target BS 2 has been finished R4 with grappling ASN-GW, the process of setting up of R6 data channel.
After step 9:Relay ASN-GW receives Path_Reg_Ack, perceive the flow process of setting up of having finished the R6 data channel, begin to trigger the pre-established data channel deletion flow process of other unchecked candidate target BS of this Relay ASN-GW management.Send Path_DeReg_Req (passage removal request) message and give target BS 1, and timer TPath_DeReg_Req1 (passage removal request timer 1) is set.Target BS 1 is replied Path_DeReg_Rsp (passage deletion response) message after receiving the data channel removal request, and optionally Relay ASN-GW replys Path_DeReg_Ack (the passage deletion is confirmed) message for target BS 1.
Step 10: grappling ASN-GW perceives the flow process of setting up of having finished the R4 data channel with RelayASN-GW after receiving Path_Reg_Ack, begin to trigger deletion flow process with the data channel of source BS, send Path_DeReg_Req to source BS, source BS replys Path_DeReg_Rsp message, and optionally grappling ASN-GW replys Path_DeReg_Ack message.
Embodiment 3
Fig. 6 is according to the selected BS of the embodiment 3 R4 mouth switching flow figure in grappling ASN-GW side, and as shown in Figure 6, selected BS is as follows at the R4 mouth switching flow of grappling ASN-GW side:
The target BS 2 of step 1:Relay ASN-GW management is initiated the pre-established request of data channel, Relay ASN-GW receives the current pre-established flow process of not finishing the R4 data channel with grappling ASN-GW of request back judgement, finish the R4 of target BS 2 with Relay ASN-GW and grappling ASN-GW, the pre-established flow process of R6 data channel for grappling ASN-GW forwards.
With flow process unanimity shown in Figure 1, target BS 1 begins to initiate the pre-established request of data channel, judge the pre-established flow process of having finished with the R4 data channel of grappling ASN-GW after the Relay ASN request of receiving, then directly reply target BS 1 up to the pre-established flow process of finishing the R6 data channel.In like manner, the target BS 3 of grappling ASN-GW management is initiated pre-established request, directly finishes the pre-established flow process with the R6 data channel of grappling ASN-GW.
Step 2: the target BS 3 of grappling this moment ASN-GW management is chosen to be the base station that switches at last, so target BS 3 begins to initiate the flow process of setting up of data channel, finishes the foundation with the R6 data channel of grappling ASN-GW.
Step 3: grappling ASN-GW perceives with selected target BS 3 and finishes after the foundation of data channel, initiation is with the deletion flow process of the data channel of source BS, simultaneously because same Relay ASN-GW has before finished the pre-established of R4 data channel, the same deletion flow process of initiating with the R4 data channel of Relay ASN-GW is finished the release of R4 data channel.
Step 4:Relay ASN-GW perceives after the release with the R4 data channel of grappling ASN-GW, judges that promptly the candidate target BS of its management all is not chosen to be target BS, so initiate the release flow process with the R6 data channel of target BS 1 and target BS 2 respectively.
In sum, it is mutual that the scheme that the embodiment of the invention provides has been simplified the flow process of R4 mouth, realized sharing of R4 data channel, reduced handover delay, optimized the performance of handoffs of striding ASN-GW.
