Embodiment
The invention provides a kind of packet switch method, its core concept is that the step that switching condition is judged is carried out in increase in switching flow, by default switching condition the initiation or the execution of current switching is controlled.This determining step can be carried out to switch and finish preceding any time, by any interdependent node in switching, for example enforcements such as travelling carriage, base station controller or general access network controller.Judge and to be provided with according to practical application with switching condition, for example, the unusual switching that causes for short trouble, the switch reasons that can switching condition is set to cause is eliminated before switching is finished, for example a kind of again comparatively general setting is that switching condition is set to travelling carriage must not switchback in a period of time after cutting out from certain sub-district.The present invention also provides the communication apparatus that is applied to above-mentioned packet switch method.Below respectively the inventive method and equipment are elaborated.
Embodiment one, a kind of packet switch method, flow process comprises as shown in Figure 1:
The handoff request that A1, travelling carriage will comprise the switch reasons sign sends to source GANC or source BSS;
Switching can be by Mobile Originated, for example, may be that travelling carriage finds that by local measurement the GAN link-quality descends, thereby send handoff request; Switch and also may initiate by network side, for example, source GANC or source BSS find the load balancing strategy of uplink quality fault or Virtual network operator, switch by link-quality indication information notice travelling carriage, and travelling carriage sends handoff request etc. according to this information;
For reaching the purpose of accurate recording switch reasons, the reason that may cause switching can be classified and is identified, for example,, can adopt the switch reasons table of comparisons as shown in the table for the switching that cuts out from the GAN sub-district:
| The switch reasons sign | Switch reasons is described |
| 0 | Radio jink failure, excessive as packet loss |
| 1 | The network link problem |
| 2 | Small area jam |
| 3 | GANC is subjected to outside world |
| 4 | Service quality is unacceptable, and is too big as postponing |
| 5 | GANC can not provide the business of travelling carriage request |
| 6 | The user manually selects to switch |
| 7 | Other unknown causes |
After A2, source GANC or source BSS receive handoff request, the switch reasons sign that record wherein carries;
A3, source GANC or source BSS judge that in carrying out follow-up handover operation process described switch reasons identifies pairing switch reasons and whether still exists, if then continue to carry out follow-up handover operation, then cancellation is switched if not;
According to existing switching flow, the follow-up handover operation that source GANC or source BSS may carry out comprises:
Send a handover request to service general grouping service wireless (GPRS, General Packet RadioService) support node (SGSN, Serving GPRS Support Node);
Receive the Handover Request Acknowledge that described SGSN returns;
Send switching command to described travelling carriage;
In said process, whether source GANC or source BSS can eliminate the reason that causes switching is at any time judged, and, judge also to be not limited to only carry out once, can be set in the front/rear execution of some step, the cycle that also can fix carries out or triggers execution by dependent event, satisfy as message arrival, network settings condition, do not finish as long as switch, source GANC or source BSS find to cause the reason elimination of switching at any time, can cancel switching;
According to practical situations,, after source GANC or source BSS can be chosen in and receive the Handover Request Acknowledge that described SGSN returns, carry out switching condition and judge as a kind of reasonable method; This moment, source GANC or source BSS can send handover cancelling message to SGSN if being judged as cancellation switches, and cancelled this and switched, and SGSN receives after the handover cancelling message that notification target BSS or target GANC are released to and switches the link circuit resource that distributes.For making SGSN, target GANC or target BS S know the cause of handoff failure, also can comprise the reason that cancellation is switched in the handover cancelling message that source GANC or source BSS send.
Switching to the GERAN sub-district with the Mobile Origination that is positioned at the GAN sub-district below is example, provides a kind of realization signaling process that adopts said method, as shown in Figure 2, comprising:
A1, travelling carriage are determined the switching of initiation from GAN sub-district, current source to target GERAN sub-district; The reason that travelling carriage is made above-mentioned switching judging may be to find that by local measurement the GAN link-quality descends, or receive that general access packet uplink quality indication (GA-PSR UplinkQuality Indication) message that GANC sends finds uplink quality fault etc., switch reasons can be represented by corresponding sign in the switch reasons table of comparisons that presets; Suppose that current switch reasons is the up-link wireless link failure, corresponding switch reasons sign " 0 ";
A2, travelling carriage send the general access grouping that comprises switch reasons sign " 0 " switch Reference News (GA-PSR Handover Information) to source GANC as handoff request, start switching; Carry cell list in this message, and the measurement report of each sub-district, GANC can select the best sub-district of signal quality as Target cell according to the receiving level strength of each sub-district in the report;
A3, source GANC write down general access grouping and switch switch reasons sign " 0 " in the Reference News;
Above-mentioned a1～a2 is the handover trigger stage, and GANC determines can initiate to switch preparation behind the Target cell;
A4, source GANC send grouping handoff request (PS Handover Required) message and switch to the SGSN request;
A5, SGSN send grouping handoff request (PS Handover Request) message and set up Radio Resource to target BS S request;
A6, target BS S are the travelling carriage Resources allocation, send grouping Handover Request Acknowledge (PS HandoverRequest Acknowledge) message and inform the resource allocation success to SGSN;
Above-mentioned a4～a6 is a handoff preparation phase, promptly finishes to switch after the target BS S notice SGSN resource allocation success and prepares;
A7, SGSN send grouping and switch confirmation request (PS Handover Required Acknowledge) message to source GANC; By this message, SGSN informs that source GANC is the travelling carriage assigned radio resource in target GERAN sub-district;
A8, source GANC carry out switching condition and judge, judge whether the switch reasons of corresponding switch reasons sign " 0 " still exists; If current up link has been recovered normally to judge that then switch reasons does not exist, carry out a9, otherwise continue to carry out a11;
A9, source GANC send packet switch cancellation (PS Handover Cancel) message to SGSN, cancel this switching, and carry reason;
A10, SGSN send deletion packet flow context (DELETE BSS PFC) message informing target BS S and are released to the link circuit resource that travelling carriage distributes after receiving the packet switch cancellation message that source GANC sends.
A11, source GANC continue to carry out follow-up handover operation, send general access grouping switching command (GA-PSR Handover Command) message to travelling carriage, order switching mobile station to target GERAN sub-district;
A12, travelling carriage send grouping and switch access (PS Handover Access) message to target BS S;
A13, target BS S send grouping physical message (Packet Physical Information) to travelling carriage;
A14, travelling carriage send Routing Area Update (Routing Area Update Request) message to target BS S;
A15, when target BS S receives the Routing Area Update message of travelling carriage or correctly receives the RLC/MAC data block that travelling carriage sends, think to switch and finish, send grouping and switch and finish (PS HandoverComplete) message to SGSN, finish switching flow.
In above-mentioned concrete signaling process, source GANC carries out switching condition to judge after receiving the Handover Request Acknowledge that SGSN returns, certainly, whenever source GANC also can carry out this judgement after receiving the handoff request of travelling carriage, as long as travelling carriage is also in the GAN sub-district, source GANC just can switch after finding the switch reasons elimination in cancellation.
In the above-described embodiments, adopted by source GANC or source BSS and carry out the method that switching condition is judged in switching, certainly, this judgement also can be undertaken by travelling carriage, and example is as follows.
Embodiment two, a kind of packet switch method, flow process comprises as shown in Figure 3:
B1, travelling carriage are initiated to the switching of target GERAN sub-district or target GAN sub-district from GAN sub-district, source or GERAN sub-district, source, handoff request is sent to source GANC or source BSS; And write down the switch reasons sign of corresponding switch reasons, with similar among the embodiment one, the switch reasons sign can obtain by actual switch reasons being carried out classifying and numbering;
B2, travelling carriage judge that in carrying out follow-up handover operation process described switch reasons identifies pairing switch reasons and whether still exists, if then continue to carry out follow-up handover operation, then cancellation is switched if not;
According to existing switching flow, the follow-up handover operation that travelling carriage may be carried out comprises:
The switching command that reception sources GANC or source BSS send;
Send to insert and ask target BS S or target GANC;
In said process, whether travelling carriage can be eliminated the reason that causes switching is at any time judged, and, judge and also be not limited to only carry out once, can be set in the front/rear execution of some step, the cycle that also can fix carries out or triggers execution by dependent event, does not finish as long as switch, travelling carriage finds to cause the reason elimination of switching at any time, can cancel switching;
According to practical situations, as a kind of reasonable method, travelling carriage carries out switching condition and judges after can being chosen in the switching command of receiving source GANC or source BSS transmission; Switch if be judged as cancellation this moment, travelling carriage can send to switch cancels message or packet cell change failed message to source GANC or source BSS, send packet switch cancellation message (PS Handover Cancel) to SGSN by source GANC or source BSS again, cancel this and switch, SGSN receives after the handover cancelling message that notification target BSS or target GANC are released to and switches the link circuit resource that distributes.For making source GANC or source BSS know the cause of handoff failure, the switching that travelling carriage sends is cancelled in message or the packet cell change failed message also can comprise the reason that cancellation is switched.
Switching to the GERAN sub-district with the Mobile Origination that is positioned at the GAN sub-district below is example, provides a kind of realization signaling process that adopts said method, as shown in Figure 4, comprising:
B1, travelling carriage are determined the switching of initiation from GAN sub-district, current source to target GERAN sub-district; Suppose that current switch reasons is the up-link wireless link failure, corresponding switch reasons sign " 0 ";
B2, travelling carriage send general access grouping switch Reference News to source GANC as handoff request, start switching; Carry cell list in this message, and the measurement report of each sub-district, GANC can select the best sub-district of signal quality as Target cell according to the receiving level strength of each sub-district in the report;
B3, travelling carriage write down the switch reasons sign " 0 " of current switching;
B4, source GANC receive handoff request, determine to initiate to switch preparation behind the Target cell, and process is with a4～a6 among the embodiment one;
B5, SGSN send grouping and switch confirmation request message to source GANC; By this message, SGSN informs that source GANC is the travelling carriage assigned radio resource in target GERAN sub-district;
B6, source GANC send general access grouping switching command message to travelling carriage, order switching mobile station to target GERAN sub-district;
B7, travelling carriage carry out switching condition to be judged, judges whether the switch reasons of corresponding switch reasons sign " 0 " still exists; If current up link has been recovered normally to judge that then switch reasons does not exist, carry out b8, otherwise continue to carry out b11;
B8, travelling carriage send general access grouping switching and cancel (GA-PSR Handover Withdraw) message to source GANC, and the notice cancellation is switched;
B9, source GANC send cancellation packet switch cancellation message to SGSN, cancel this switching, and carry the cancellation reason;
B10, SGSN send deletion packet flow context (DELETE BSS PFC) message informing target BS S and are released to the link circuit resource that travelling carriage distributes after receiving the packet switch cancellation message that source GANC sends.
B11, travelling carriage are carried out the access of target GERAN sub-district, and process is with a12～a15 among the embodiment one.
In above-mentioned concrete signaling process, travelling carriage is to carry out switching condition to judge after receiving the general access grouping switching command message that source GANC sends, certainly, travelling carriage also can be after sending handoff request whenever carry out this judgement, as long as travelling carriage also in the GAN sub-district, just can switch after finding the switch reasons elimination in notification source GANC cancellation.
In addition, carrying out switching condition by network side or end side respectively in above-mentioned two embodiment judges, in actual applications, can also be in conjunction with above-mentioned two kinds of judgment modes, all use the switching condition judgment mechanism at network side and end side, any one party discovery switch reasons is eliminated and can be initiated handover cancelling, and in this case, switch reasons both need have been preserved by terminal also be needed to send to network side by handoff request.
More than, provided several employing switch reasons and whether disappeared as the present invention program of switching condition, in addition, also can be simply by the control of switching time being avoided the unusual generation of cutting of returning, example is as follows.
Embodiment three, a kind of packet switch method, flow process comprises as shown in Figure 5:
C1, travelling carriage start switching timer after switching to current GAN sub-district, source of living in or GERAN sub-district, source;
C2, travelling carriage determine to need to initiate new the switching in current area;
C3, travelling carriage judge whether described switching timer is overtime, if then carry out the initiation of switching, then forbid the initiation of switching if not.
In said method, a kind of typical situation is that travelling carriage is currently located at the GERAN sub-district, and it initiates the new Target cell that switches is the GAN sub-district; At this moment, as a kind of reasonable method, travelling carriage is forbidden the initiation of switching, can be by in the measurement report that is reported to source BSS, getting rid of the mode of this target GAN sub-district, like this, measurement report promptly can not be triggered to the switching flow of this GAN sub-district, reaches to forbid the purpose switched.
Certainly, the switching timer that travelling carriage starts also can be associated with specific sub-district, and only when the switching object of travelling carriage was the specific cell of association, just whether overtime execution was judged to timer.For example, switching timer is related with preceding cell-of-origin of once switching, avoid switchback in the short time; Or, with the GAN cell association of current registration, avoid between GAN sub-district and GERAN sub-district, frequently switching.
The timing length of switching timer can send to travelling carriage by system message or control signaling by source BSS in the travelling carriage; Perhaps, also can notify travelling carriage when the mobile station login by GANC; Perhaps, also can define voluntarily by travelling carriage.
In a last embodiment, adopt the mode of carrying out switching timing control by travelling carriage; Switching timer also can be arranged on network side, and example is as follows.
Embodiment four, a kind of packet switch method, flow process comprises as shown in Figure 6:
D1, travelling carriage are after switching to current GAN sub-district, source of living in or GERAN sub-district, source, and source GANC or source BSS start switching timer for this travelling carriage;
D2, travelling carriage are initiated new the switching in current area, handoff request is sent to source GANC or source BSS;
D3, source GANC or source BSS judge whether the switching timer of this travelling carriage is overtime before carrying out follow-up handover operation, if then continue to carry out follow-up handover operation, then refuse this handoff request if not.
D1 source GANC or source BSS start switching timer in travelling carriage incision back.
In said method, a kind of typical situation is that travelling carriage is currently located at the GERAN sub-district, and it initiates the new Target cell that switches is the GAN sub-district; At this moment, as a kind of reasonable method, the handoff request of source BSS refusal travelling carriage can comprise Reason For Denial by switching refuse information notice travelling carriage, switching in the refuse information, moves as switching timer; Perhaps source BSS also can not respond handoff request, allows travelling carriage judge whether to continue request voluntarily and switches to the GAN sub-district.The timing length of timer can be defined voluntarily by source BSS or source GANC among source BSS or the source GANC.
In order to make travelling carriage understanding source BSS or source GANC to the control situation of switching timing, can adopt the method for timer length being notified travelling carriage, for example, send to travelling carriage by system message or control signaling by source BSS; Perhaps, also can notify travelling carriage when the mobile station login by GANC.
Certainly, the switching timer that source BSS or source GANC start also can be associated with specific sub-district, and only when the switching object of travelling carriage was the specific cell of association, just whether overtime execution was judged to timer.For example, the cell-of-origin that switching timer and travelling carriage are cut before this sub-district is related, avoid switchback in the short time.In addition, a kind of typical situation is, travelling carriage is currently located at the GERAN sub-district, and the switching timer that source BSS starts and the GAN cell association of the current registration of travelling carriage are avoided travelling carriage frequently switching between GAN sub-district and GERAN sub-district.
Under above-mentioned timer and situation that specific cell is associated, handoff request for fear of travelling carriage can not get response or execution for a long time, a kind of reasonable method is, source BSS or the source GANC travelling carriage that sends a notification message, inform the destination object that the current permission of travelling carriage is switched: for example, source BSS or source GANC can be behind timer expiries, and the notice travelling carriage is current can be again to switch trial to the affiliated partner of timer; Perhaps, if travelling carriage at the switching timer run duration, repeatedly sends handoff request, source BSS or source GANC also can be according to corresponding adjustment strategies, and the notice travelling carriage attempts switching to other targets that do not belong to the timer affiliated partner.
In fact whether embodiment one, two and three, four schemes of having described respectively based on two kinds of different judgment mechanisms, eliminate scheme of judging and the scheme that adopts timer to switch reasons and also can comprehensively use.For example, before handover trigger, judge whether to allow handover trigger by timer; After handover trigger, judge whether to continue to carry out to switch the such scheme use of can arranging in pairs or groups flexibly at any time according to the state of switch reasons.
