Description
Technical field
The present invention relates to field of mobile communication, the reconciliation blocking method is blocked in particularly a kind of sub-district.
Background technology
In 3G (Third Generation) Moblie TD SDMA (TD-SCDMA) standard, it is NBAP (Node B Application Part that the sub-district is blocked, NBAP) a kind of basic process in the agreement, in this process, (Controlling Radio Network Controller CRNC) blocks designated cell according to the request of base station (Node B) to the control radio network controller.
Fig. 1 is the flow chart that process is blocked in the sub-district in the prior art.As shown in Figure 1, sub-district of the prior art obstruction process comprises the steps:
Step 101, Node B sends resource to CRNC and blocks request (Block Resource Request) message.
When initiating sub-district obstruction process, Node B sends Block Resource Request message by the control port of Node B to CRNC, and this message is carried the designated cell sign, and CRNC carries out blocking operation to designated cell with request.
Step 102, CRNC carries out blocking operation to designated cell.
Block Resource Request message is also carried and is blocked priority indication information element (BlockingPriority Indicator IE), CRNC carries out the value decision of the detailed process of blocking operation by Blocking PriorityIndicator IE, Blocking Priority Indicator IE has three kinds of values, is used for representing respectively three kinds of sub-districts obstruction classifications: high priority, normal priority and low priority.
When initiating high priority sub-district obstruction, CRNC forbids the relevant resource of the sub-district of appointment immediately, promptly blocks designated cell.After designated cell got clogged, this sub-district can not be admitted new business again.
When initiating normal priority sub-district obstruction, CRNC need judge the state of designated cell, if this sub-district is in idle condition, blocks this sub-district immediately; If designated cell is non-idle condition, promptly also have the user making a phone call or surfing the Net in the sub-district, CRNC need wait for a period of time.After waiting for a period of time, if designated cell still is busy state, CNRC initiatively discharges the online user of designated cell, blocks this sub-district then.The timer cell (Shutdown Timer IE) that the concrete stand-by period of CRNC is carried by Block Resource Request message is determined.In addition, need to prove, in actual applications, CRNC receive behind the Block Resource Request can the detection of dynamic designated cell state, if also have the user making a phone call or surfing the Net in the sub-district, represent that then the sub-district is busy,, then represent the sub-district free time if there is not the user making a phone call or surfing the Net in the sub-district.
Wherein, initiatively discharge the online user and be meant the business of forcing the release user using, for example forced interruption conversation when user's communication.
When the sub-district of initiating low priority was blocked, CRNC also needed to judge the state of designated cell, if designated cell is in idle condition, blocks this sub-district immediately; If busy state, CRNC need wait for after the sub-district is changed idle condition into just can block this sub-district, promptly needs to wait for and just blocks this sub-district when not having the online user in the sub-district.Because when uncontrollable online user discharges business, so in this case, the concrete stand-by period can't be determined.
Step 103, CRNC returns resource to Node B and blocks response (Block Resource Response) message.
NBAP agreement regulation, after CRNC carried out the blocking operation success to designated cell, CRNC sent Block Resource Response message to Node B.
Based on above-mentioned sub-district blocking method, Fig. 2 is the unblock flow chart of process of sub-district in the prior art.As shown in Figure 2, the district's blocking method of going to the lavatory of the prior art comprises the steps:
Step 201, Node B sends resource indication (unBlock ResourceIndication) message that unblocks to CRNC.
When the initiation sub-district unblocked process, Node B sent unBlock Resource Indication message by the control port of Node B to CRNC, and this message is carried the sign of designated cell, and CRNC carries out the operation that unblocks to designated cell with request.
Step 202, CRNC carries out the operation that unblocks to designated cell.
CRNC recovers the employed related resource of designated cell, the designated cell that promptly unblocks, and after designated cell was unblocked, new business can be continued to admit in this sub-district.
As seen, in the sub-district blocking method that prior art provided, when initiating normal priority sub-district obstruction, if designated cell is not an idle condition, CRNC need wait for a period of time, after waiting for a period of time, if designated cell still is busy state, CNRC could block designated cell after initiatively discharging the online user of designated cell, when the sub-district of initiating low priority was blocked, if designated cell is not an idle condition, CRNC also needed to wait for after designated cell becomes idle condition and just can carry out blocking operation, therefore, the execution efficient of sub-district obstruction is lower.
Summary of the invention
In view of this, the invention provides a kind of sub-district and block the reconciliation blocking method, can improve the execution efficient that the sub-district is blocked.

Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, scheme of the present invention is described in further detail.
Fig. 3 is the flow chart of a kind of sub-district provided by the present invention blocking method.As shown in Figure 3, this method may further comprise the steps:
Step 301, Node B sends resource to CRNC and blocks request (Block Resource Request) message, and this message is carried the designated cell sign, blocked priority indication information element (Blocking PriorityIndicator IE) and timer cell (Shutdown Timer IE).
Step 301 can be with reference to the content of step 101 in the prior art.
Step 302, CRNC judges that according to Blocking Priority Indicator IE the sub-district blocks classification, if classification is blocked when being high priority in the sub-district, direct execution in step 307 then; If when sub-district obstruction classification was normal priority, then execution in step 303; If when sub-district obstruction classification was low priority, then execution in step 303.
Step 303, CRNC identifies according to designated cell, judges whether designated cell is idle condition, if then execution in step 307; Otherwise execution in step 304.
CRNC judges that the method for cell status is the content of prior art, will not give unnecessary details herein.
Step 304, CRNC sends cell re-configuration request (Cell ReconfigurationRequest) message to Node B, request is with the Primary Common Control Physical Channel of designated cell (Primary CommonControl Physical Channel, P-CCPCH) the transmission power level minimum value that is configured to set in advance.
According to the relevant regulations of the 9.2.3.9 of 3GPP agreement 25.433 versions joint, P-CCPCH transmission power level span is-15 to 40 dBms (dbm), and visible minimum value is-15dbm.
It will be appreciated by those skilled in the art that, when the user sets up professional a sub-district, for example conversation, afterwards, subscriber equipment can constantly be measured the intensity of the P-CCPCH transmitting power of this sub-district and neighbor cell, and the measured value of P-CCPCH transmitting power is reported radio network controller, and (Radio NetworkController, RNC), RNC judges whether that according to these values needs switch to other neighbor cells with the user.Generally speaking, if the signal of sub-district, subscriber equipment place is very weak, be that its P-CCPCH transmission power level that receives this sub-district is very little, and there is a signal better cell, it is bigger to be that the user receives the P-CCPCH transmission power level of this sub-district, subscriber equipment can initiatively switch to the good adjacent TD-SCDMA sub-district of signal or global system for mobile communications (Global System for MobileCommunications, GSM) sub-district.
In the present invention, the P-CCPCH transmission power level of the sub-district that gets clogged is reduced to after the minimum value, the power of user's Traffic Channel can not be affected, and can not cause that promptly the user goes offline, and still, the user can initiatively switch to the good sub-district of signal.And in the prior art, when initiating normal priority sub-district obstruction, if designated cell is non-idle condition, CRNC need wait for a period of time, after waiting for a period of time, if designated cell still is busy state, CNRC can initiatively discharge the online user of designated cell, and in the process that initiatively discharges, CNRC can force to discharge the business that the user is using, for example forced interruption conversation when user's communication promptly causes conversation loss.
In addition, in actual environment, because there is path loss in signal in communication process, so the P-CCPCH transmission power level that this community user actual reception arrives will be littler, like this, the easier triggering of RNC user initiatively switches to the good neighbor cell of signal.
Step 305, Node B is according to Cell Reconfiguration Request message, the minimum value that the P-CCPCH transmission power level of designated cell is configured to set in advance.
In this step, also can further comprise the steps: after the minimum value that the P-CCPCH transmission power level of designated cell is configured to set in advance
If configuration successful, then Node B returns cell re-configuration success response (CellReconfiguration Response) message to CRNC, the reprovision that CRNC is provided with designated cell successfully identifies, the expression designated cell the P-CCPCH transmission power level in the obstruction process once by successful reprovision mistake, as the reference of the follow-up method that unblocks, execution in step 306 again after reprovision is set successfully identifies; Otherwise Node B returns cell re-configuration failure (Cell Reconfiguration Failure) message to CRNC, and execution in step 306 then.
Need to prove, if reprovision failure, the subscriber equipment that then can not effectively trigger designated cell initiatively switches to other good neighbor cells of signal by designated cell, but still can block flow performing by the sub-district of prior art, that is to say, can not interrupt even flow process is blocked in reprovision failure, sub-district, still can carry out smoothly.
306, if classification is blocked when being normal priority in the sub-district, CRNC judges whether designated cell is idle condition, if then execution in step 307; Otherwise, CRNC waits for a period of time, after waiting for a period of time, if designated cell changes idle condition into, then execution in step 307, if or busy state, CNRC initiatively discharges the online user of designated cell, execution in step 307 then, and wherein, described wait duration is the value of the Shutdown Timer IE that carries of Block Resource Request message;
If when sub-district obstruction classification was low priority, CRNC judged whether designated cell is idle condition, if then execution in step 307; Otherwise CRNC waits for that designated cell changes execution in step 307 after the idle condition into.
Step 307, CRNC carries out blocking operation to designated cell.
Step 308, CRNC returns resource to Node B and blocks response (Block Resource Response) message.
So far, this flow process finishes.
Based on above-mentioned sub-district blocking method, Fig. 4 is the unblock flow chart of method of a kind of sub-district provided by the present invention.As shown in Figure 4, this method may further comprise the steps:
Step 401, Node B sends resource indication (unBlock ResourceIndication) message that unblocks to CRNC, and this message is carried designated cell and is identified.
Step 402, CRNC identifies according to designated cell, and designated cell is carried out the operation that unblocks.
Step 403, CRNC judges whether that the reprovision that is provided with designated cell successfully identifies, if once by successful reprovision mistake, then execution in step 404 in the obstruction process of sub-district for the P-CCPCH transmission power level of expression designated cell; Otherwise, process ends.
Step 404, CRNC sends cell re-configuration request (Cell ReconfigurationRequest) message to Node B, the P-CCPCH transmission power level of designated cell is revised in request, and CellReconfiguration Request message is carried the P-CCPCH transmission power level.
Step 405, the P-CCPCH transmission power level that Node B carries according to Cell Reconfiguration Request message, revise the P-CCPCH transmitting power of designated cell, that is to say, the P-CCPCH transmission power level of sub-district is revised as the performance number that Cell Reconfiguration Request message is carried.
In addition, after step 405, can comprise the steps: further that also Node B judges whether modification is successful, if success, then Node B returns cell re-configuration success response (CellReconfiguration Response) message to CRNC; Otherwise, Node B returns cell re-configuration failure (Cell Reconfiguration Failure) message to CRNC, after sending failed message, Node B can directly be set at the P-CCPCH transmission power level a predefined default value, wherein, the concrete numerical value of default value is determined on a case-by-case basis.
So far, this flow process finishes.
To sum up, in the present invention, when sub-district obstruction classification is high priority, directly designated cell is carried out blocking operation; And when sub-district obstruction classification is normal priority, if the state of sub-district is non-idle condition, then after the minimum value that the P-CCPCH transmission power level of designated cell is configured to set in advance, CRNC judges whether designated cell changes idle condition into, if, then designated cell is carried out blocking operation, otherwise, CRNC waits for a period of time, after waiting for a period of time, if designated cell changes idle condition into, then designated cell is carried out blocking operation, if or busy state, CNRC initiatively discharges the online user of designated cell, then designated cell is carried out blocking operation; And when sub-district obstruction classification is low priority, if the state of sub-district is non-idle condition, then after the minimum value that the P-CCPCH transmission power level of designated cell is configured to set in advance, CRNC judges whether designated cell changes idle condition into, if, then designated cell is carried out blocking operation, otherwise CRNC waits for after designated cell changes idle condition into designated cell is carried out blocking operation.
As seen, when sub-district obstruction classification is normal priority, because the minimum value that the P-CCPCH transmission power level of designated cell is configured to set in advance, the subscriber equipment that can trigger designated cell switches to other good neighbor cells of signal by designated cell, if whole subscriber equipmenies of designated cell all switch to other neighbor cells, then designated cell changes idle condition into, can carry out blocking operation to designated cell immediately, improved the execution efficient that the sub-district is blocked, and for blocking classification when being low priority in the sub-district, also be similarly, can improve the execution efficient that the sub-district is blocked.
In addition, blocking classification for the sub-district is normal priority, with the P-CCPCH transmission power level of the sub-district that gets clogged is after the minimum value, the power of the Traffic Channel of subscriber equipment can not be affected, the online user can not go offline or call drop because P-CCPCH power reduces in the sub-district like this, but the P-CCPCH transmitting power of this sub-district that the user receives declines to a great extent, so the user can initiatively switch to other good neighbor cells of signal by this sub-district.
