Embodiment one
Fig. 2 is the first embodiment of the present invention, is the example that the base station from home triggering terminal is moved back the net flow process.In the present embodiment, suppose that terminal (terminal use) is the CSG member of base station from home, and the current serving BS of terminal is this base station from home (that is, terminal is current is linked in the wireless network by this base station from home).
Specifically comprise following steps:
Step 201: base station from home is received the CSG member management request of cancellation terminal (terminal use) as its closed subscriber group (CSG) membership qualification, comprises this terminal (terminal use's) sign in this request.Wherein, the local management interface on the base station from home be can use, relevant request and parameter imported by the mode of manual input by the owner of base station from home.
Base station from home sends deletion CSG member request to base station from home management system (WiMAX Femto Management System), with the qualification of request cancellation terminal as this base station from home CSG member.Base station from home sends to the base station from home management system by this message with the sign of above-mentioned terminal iidentification and base station from home self.
Above-mentioned terminal (terminal use) sign, comprise MAC Address (Media Access ControlAddress, Media Access Control address), MSID (Mobile Station Identify, mobile station identification), Real-NAI (Real Network Access Identity, live network inserts sign), USI (UniversalServices Interface Identity, general service interface sign) etc.
Step 202: the base station from home management system is handled deletion CSG member request, and the agreement base station from home is deleted terminal from its CSG member.
What deserves to be explained is, the base station from home owner also can by other modes notify the base station from home management system he want terminal is deleted from the CSG member of his base station from home, for example, this owner can inform his demand by the mode of telephone operator, informs the sign of terminal and the sign of base station from home etc. simultaneously.In this case, step 201 can not carried out.
Step 203: the base station from home management system sends deletion CSG member to base station from home and asks response, and the notice base station from home is with terminal deletion from its CSG member's tabulation.This message need be carried the sign of above-mentioned terminal.
Step 204: base station from home is carried out the instruction with terminal deletion from its CSG member's tabulation, and initiates a message to terminal, moves back net with indicating terminal.
In this step, because this base station from home is the serving BS of terminal, then base station from home needs suitable this terminal of processing, and base station from home can send to nullify to terminal orders (DREG_CMD (Ation Code=0x00)) to come triggering terminal to move back net (Network Exit).
Before triggering terminal was moved back net, base station from home can also be judged the current business of carrying out of terminal, whether needed to postpone triggering terminal with decision and moved back net, the situation that for example following example is described:
First example, if base station from home know terminal current carrying out urgency traffic (as, dial 110), then base station from home can postpone to carry out the instruction with terminal deletion from its CSG member's tabulation, and allow this urgency traffic continue to carry out (that is, temporarily do not send and nullify order) to terminal.Base station from home can know in several ways whether terminal is carrying out urgency traffic, such as:
Mode one, base station from home can be known the current urgency traffic that carrying out of terminal by the idle message of terminal.Terminal can be carried a marker bit in its idle message when carrying out urgency traffic, indicate terminal and will carry out urgency traffic, and base station from home can be known according to the state of this marker bit;
Mode two, base station from home can be known the current urgency traffic that carrying out of terminal by the contextual information of terminal.Terminal can comprise relevant indication information in its contextual information when carrying out urgency traffic.This contextual information can perhaps be preserved by the anchor point authentication device (Anchor Authenticator) of terminal by the serving BS (at this moment, this base station from home is exactly the serving BS of terminal) of terminal.If preserved by the anchor point authentication device, then base station from home can ask to judge whether this terminal is carrying out urgency traffic to the anchor point authentication device.
When knowing that terminal is being carried out urgency traffic, after base station from home can wait until that the urgency traffic of terminal is finished, send to terminal again and nullify order; Perhaps, base station from home can wait for that also terminal finishes urgency traffic, when carrying out network re-entry, and the request of refusal terminal network re-entry.
Second example, the strategy that depends on base station from home (can be disposed by operator, also can dispose voluntarily) by the owner of base station from home, if current terminal just in execution priority than higher business (for example, conversation), then base station from home also can postpone triggering terminal and moves back net, wait for terminal this business is finished after again triggering terminal move back net.In this example, base station from home also can use the method for aforesaid way two, promptly by the contextual information of terminal, judges the current business of whether carrying out of terminal, and whether performed business is higher priority business.
Step 205: terminal is carried out and is moved back the net flow process.
Terminal move back the net flow process, comprise that terminal discharges the IP address, nullify data channel, and stop the charging of terminal etc.
Step 206: base station from home with terminal from its CSG member deletion of tabulating.
Certainly, base station from home also can ask to respond later any time the deletion CSG member who receives step 203, with terminal deletion from its CSG member's tabulation.
By the foregoing description, it is unexpected to avoid terminal mentioned above to meet with, unexpected service disconnection.Simultaneously, move back the support of net function by base station from home to postponing triggering terminal, terminal can be withdrawed from from network after level and smooth end current business (particularly urgency traffic) again, make base station from home to provide service to the user more humanely, improve user's satisfaction.This embodiment has also solved under this scene, and Internet resources can not get the problem of normal process,, moves back net by triggering terminal that is, reaches the purpose of releasing network resources, has avoided network resources waste.
What deserves to be explained is, what above-mentioned steps 204 was described is that base station from home directly comes triggering terminal to move back the example of net to terminal transmission cancellation order, in fact base station from home also can no longer be with this terminal its CSG member's this status report give terminal the anchor point authentication device (for example, the mode of false information of more than reporting an error sends to the anchor point authentication device with above-mentioned state), initiate to make the flow process of terminal exiting network then by the anchor point authentication device.
In this case, the anchor point authentication device need send terminal exiting network Indication message (NetExit_MS_State_ChangeReq) to the IAD of terminal; IAD sends data channel de-registration request message (Path_Dereg_Req) to base station from home then; Receive after the above-mentioned message that base station from home sends to terminal and nullifies order, moves back net with triggering terminal.In this implementation, when needs delay triggering terminal was moved back net, base station from home can postpone to send above-mentioned state to the anchor point authentication device; Also can determine whether that needing to postpone triggering terminal moves back net by the anchor point authentication device, at this moment, the anchor point authentication device can be known the type of the current business of carrying out of terminal according to the method for describing in the step 204.
The method that present embodiment proposes is specially adapted to the scene that base station from home is disposed separately, i.e. the covering of base station from home becomes the isolated island shape, and it does not have available neighbours base station.
Embodiment two
Fig. 3 is the second embodiment of the present invention, and is the same with first embodiment, suppose that terminal (terminal use) is the CSG member of base station from home, and the current serving BS of terminal is this base station from home.But different with first embodiment is, present embodiment supposes that this base station from home has available neighbours base station, i.e. the deployment of base station from home is not an isolated island.Specifically comprise following steps:
Step 301 is to step 303: with step 201 to step 203.
Step 304: base station from home is carried out the instruction with terminal deletion from its CSG member's tabulation, and selects suitable target BS for this terminal, and triggering switches to this terminal on the target BS.
In this step, because this base station from home is the serving BS of terminal, then base station from home needs suitable this terminal of processing.At this moment, this base station from home can be in its neighbours base station, select one or several suitable base stations, and send handoff request (HO_Req) message to these base stations, carry out the handoff preparation phase (Handover Preparation Phase) that terminal is switched to trigger, deserving to be called and stating these neighbours base stations is the candidate target base station that terminal is switched.
With the method for describing in the step 204, before sending above-mentioned handoff request message, base station from home also can be judged the current business of carrying out of terminal, whether needing to postpone triggering terminal with decision switches, for example, current terminal is being carried out urgency traffic, after then base station from home can wait until that this urgency traffic is finished, triggering terminal is switched again, and this can depend on the strategy of base station from home.
In this step, what deserves to be explained is that above-mentioned candidate target base station (the neighbours base station of this base station from home) can be a macro base station, also can be other base station from home.
Step 305: after the handoff request of above-mentioned base station from home is sent, in the presence of terminal, base station from home (serving BS) and candidate target base station (one or more), finish the handoff preparation phase of terminal.
In the handoff preparation phase implementation, base station from home can send terminal handoff request (MOB_BSHO_REQ) message to terminal, need carry out handover operation with the notice terminal, simultaneously above-mentioned candidate target base station is informed terminal; When switching preparatory stage, above-mentioned candidate target base station (one or more) can obtain the contextual information of terminal, and prepares for follow-up handover execution stage.
Step 306: after handoff preparation phase is finished, base station from home can initiatively send to switch to the candidate target base station (one or more) of above-mentioned selection at once confirms (HO_Cnf) message, so that these target BS are carried out the preparation of waiting for that the terminal switching enters; Base station from home can wait for that also terminal sends handoff request (MOB_HO-IND) message to it, the preferred target BS of carried terminal in this request message, at this moment, base station from home only need send above-mentioned switch acknowledgment message to this target BS, makes it to carry out the preparation of waiting for that the terminal switching enters.
Step 307: terminal sends distance measurement request (RHG REQ) message to target BS, carry out to switch, switch near it a target BS from base station from home on.
Step 308: target BS sends handoff completion message to base station from home, and base station from home is responded to switch to target BS and finished acknowledge message.
Step 309: with step 206, base station from home is with the deletion from its CSG member's tabulation of this terminal.
Certainly, base station from home also can be deleted CSG member and ask to respond later any time in receiving step 303, with terminal deletion from its CSG member's tabulation.
What deserves to be explained is, claim the execution phase (HandoverAction Phase) of step 306 to step 309 is switched for terminal.In fact, step 306 can not carried out yet, and after switching preparatory stage (being after the step 305), terminal can directly send distance measurement request (RHG REQ) message to target BS, carries out handover operation.
By the foregoing description, it is unexpected to avoid terminal mentioned above to meet with, and unexpected service disconnection has guaranteed the professional continuity (terminal switches to can continue current ongoing business on other base stations) of terminal execution simultaneously., can guarantee that more terminal finishes some important business (for example, urgency traffic) earlier, and then switch on other base stations postponing the support of triggering terminal handoff functionality by base station from home, improve user's satisfaction.This embodiment has also solved under this scene, and Internet resources can not get the problem of normal process, that is, switch by triggering terminal, reaches to make original Internet resources continue the purpose that can be used by terminal, has avoided network resources waste.
The method that present embodiment proposes is specially adapted to the deployment scenario that base station from home has the neighbours base station.
It should be noted that in above-mentioned two embodiment, describe that base station from home can be received the request of the requirement cancellation terminal of base station from home owner input as this base station from home CSG membership qualification by for example local management interface as step 201.
At this moment, as a kind of distortion to the foregoing description, base station from home also can be carried out triggering terminal earlier and move back net or switching, and then sends deletion CSG member request to the base station from home management system.For example, in embodiment one, at first execution in step 204 and 205, and then execution 201-203 and 206; In embodiment two, at first execution in step 304 to 308, and then carry out 301-303 and 309.Perhaps, adopt another kind of distortion, that is, the base station from home triggering terminal is moved back net or switching and base station from home to the concurrent execution that sends a request message of base station from home management system, for example in first embodiment, step 204-205 can with the concurrent execution of step 201-203; In a second embodiment step 304-308 can with the concurrent execution of step 301-303.No matter adopt the distortion of which kind of mode, its essence is all identical with principle, therefore, repeats no more.
Existing network technology also provides a kind of function that hot line keeps (Hot-Lining) that is referred to as.The basic purposes of this function is, the business of carrying out when terminal meets with unexpected problem, and when causing normally carrying out, the professional hot line that network is being carried out terminal is hung up, and the reason that is suspended of its business of notice terminal.Wait for that terminal (terminal use) has solved after this problem, recovers the business of terminal again.For example, terminal is being carried out data service, at this moment, the account balance deficiency of terminal, promptly terminal has suffered from problem.Then network can use above-mentioned hot line to keep function, terminal data service is hung up, and notify the terminal use its Sorry, your ticket has not enough value.After the wait user supplements with money again (that is, it is sufficient that remaining sum has become), network is removed above-mentioned hot line again and is kept, and recovers terminal data service.Wherein, hot line maintenance application function (HLA, Hot-Lining Application) and hot line maintenance equipment (HLD, Hot-Lining Device) are two important function entities that the existing techniques in realizing hot line keeps.
HLA generally serves as the data of the terminal that is in the hot line hold mode, is in the transmission of terminal of hot line hold mode and the data of reception and can be transferred to the HLA buffer memory; After treating that terminal hot line hold mode is removed, HLA can mail to real destination with its data in buffer again; The hot line that HLD is used for carrying out terminal traffic keeps.For example, terminal is mail to extraneous hijacking data and forwards HLA to, perhaps the external world is mail to the hijacking data of terminal and forwarded to HLA.The hot line that the aaa server of terminal and above-mentioned HLA can be used for triggering terminal traffic keeps.
Embodiment mentioned above one and embodiment two are base station from home is receiving that with terminal triggering terminal is moved back the example of net or switching from its CSG member's tabulation after the deletion.In fact, base station from home also can be before triggering terminal be moved back net or is switched, and the hot line that triggers terminal keeps, and notifies terminal (terminal use) its reason that is kept by hot line by hot line maintenance mechanism.
Embodiment three
Fig. 4 is the third embodiment of the present invention, and is the same with first embodiment, suppose that terminal (terminal use) is the CSG member of base station from home, and the current serving BS of terminal is this base station from home.Different is that the indication that terminal is deleted was received in the family expenses base station from its CSG member's tabulation after, the hot line that at first triggers terminal kept, and specifically comprises following steps:
Step 401 is to step 403: with step 201 to step 203.
Step 404: base station from home reports the incident of this terminal of cancellation as its CSG member to HLA.
Receive after the indication with the deletion from CSG member's tabulation of base station from home of this terminal, base station from home needs this information is reported HLA.The address of HLA can configured in advance in the family expenses base station, or be kept in the contextual information of terminal, base station from home can get access to the address of HLA.In this step, HLA can also return response message to base station from home, and this message of notice base station from home is received.HLA can also pass through this response message, notifies base station from home HLA whether this terminal can be changed to the hot line hold mode.If not can, then base station from home can use embodiment one or two method that terminal is handled.
Step 405:HLA sends the indication that triggers the maintenance of terminal execution hot line to the aaa server of terminal.
Step 406:AAA server sends hot line to HLD and keeps indication, and HLD keeps the indication response message to aaa server response hot line simultaneously.
What deserves to be explained is that HLD generally is arranged in IAD, can certainly be positioned at other places.
Step 407 send to be chargeed to aaa server to 408:HLD and is stopped request, is used to stop the charging to current active business.Then, HLD sends a charging that has hot line maintenance mark to aaa server again and begins request, and the terminal that is used to begin being in the hot line hold mode is chargeed.
Step 409: at this moment, the business datum of terminal all is sent to HLA.
After this, HLA can notify the terminal use, and its terminal has not been the CSG member of base station from home, and its business of carrying out may will be interrupted.HLA can notify the terminal use by a lot of modes, for example, and voice suggestion, perhaps short message prompt or the like.
After terminal had solved current existing problems, for example the base station from home owner increased to terminal its CSG member once more, and base station from home can receive the indication from the base station from home management system, similar step 403, and only message becomes increases CSG member's response.Base station from home can send an event notice to HLA once more, inform that this terminal of HLA has become its CSG member, then this moment, HLA will send a hot line and keep removing message by the aaa server to terminal, the hot line of cancelling terminal keeps, and makes terminal recover its business normally.If when the hot line to terminal keeps finishing, terminal (does not for example have to solve the problem that exists, maximum duration timer expiry to the maintenance of terminal hot line), HLA can trigger execution terminal exiting network is operated, perhaps cancel the hot line of terminal is kept, and trigger terminal carried out by base station from home and move back net or handover operation.Certainly, the above-mentioned maximum duration timer that the terminal hot line is kept also can be placed on the base station from home, is judged by base station from home, keeps under the unrevoked situation at timer expiry and hot line, and the base station from home triggering is carried out terminal and moved back net or switching.
Embodiment four
Fig. 5 is the fourth embodiment of the present invention, different with the 3rd embodiment is, in the present embodiment, base station from home with terminal by the aaa server of the event notice of deletion from its CSG member tabulation to terminal, and trigger hot line hold mode to terminal by aaa server, specifically may further comprise the steps:
Step 501 is to step 503: with step 201 to step 203.
Step 504: base station from home sends the notice terminal by the Indication message of deletion event from its CSG member's tabulation to IAD (HLD).
Step 505: IAD (HLD) sends above-mentioned incident to the aaa server of terminal.
IAD (HLD) can send to aaa server with above-mentioned incident by the Access-Request message in the radius protocol.
The hot line that the decision of step 506:AAA server triggers terminal keeps, and sends response message to IAD (HLD).
Aaa server can notify HLD to initiate the hot line of this terminal is kept by the Access-Accept message in the radius protocol.
Step 507: IAD (HLD) can also send response message to base station from home, and network will be carried out the information that hot line keeps to terminal notify this base station from home.
Step 508 is to step 510: with step 407 to 409.
Identical with embodiment three, after this, HLA can it be deleted from the CSG tabulation of base station from home with suitable method notice terminal.Similar with the 3rd embodiment, if the solution of terminal success this problem, then base station from home can pass through IAD (HLD) once more to aaa server transmission message, the notice terminal becomes its CSG member again, then aaa server can send indication to HLD, releasing keeps the hot line of terminal, and recovers the business of terminal.
In the present embodiment, what deserves to be explained is that in general, HLD is arranged in IAD, then base station from home can directly send above-mentioned message to this IAD (HLD) according to the method for embodiment description.If HLD is not positioned at IAD, base station from home still can be notified aaa server with above-mentioned event message by IAD, at this moment, aaa server can find the HLD into Terminal Service, and sends the indication of carrying out/cancelling the maintenance of terminal hot line to this HLD.
In addition, what deserves to be explained is, in above-mentioned two embodiment (embodiment three, four), base station from home also can be according to embodiment one described method, when finding that terminal is being carried out urgency traffic or higher priority business, the hot line that postpones to trigger terminal keeps, and to guarantee preferentially to carry out urgency traffic or higher priority business, this does not influence the essence of embodiment three, four.
