Description
Technical field
The present invention relates to the scrambler resource collocation method of a kind of moving communicating field TD SDMA (TD-SCDMA) system, particularly at the collocation method of the shared time slot scrambler resource of multimedia broadcast multi-broadcasting business (MBMS) of single carrier frequency network (SFN).
Background technology
Scrambler is used to distinguish the signal of various information source (be different transmitting terminals, can be understood as sub-district and base station), does not change the bandwidth of spread-spectrum signal.Totally 128 scramblers in the TD-SCDMA system, 4 scramblers of each cell configuration, but general 1 of only using wherein leaves different operators for for all the other 3 and uses.The scrambler of TD-SCDMA system and training sequence (Midamble) are corresponding one by one, receiver comes the impulse response of calculating channel successively with 4 Midamble sign indicating numbers of cell configuration, the maximum is defined as the Midamble sign indicating number that use the sub-district, has determined that the Midamble sign indicating number that use the sub-district just equals to have known corresponding scrambler.Enhancing MBMS (multimedia broadcast multicast) business among the 3GPP has proposed the single-frequency spot net (SFN) that a common cell sign of a kind of usefulness (common cell id) identifies.In this network, identical MBMS service signal is launched in a plurality of sub-districts synchronously.Receiving terminal is considered as multipath signal with the signal that these come from a plurality of sub-districts, by merging these signals the interference of minizone is transformed into useful signal energy, thereby has improved spectrum efficiency, makes higher service rate become possibility.
In the SFN network, be directed to the MBMS business, common cell sign (Common cell id) is used the scrambler and the Midamble sign indicating number of same set of time slot.Among the 3GPP scrambler of SFN sub-district is configured in the sub-district and sets up in the process and finish, with scrambling code information directly as the option of sub-district time slot configuration information.The sub-district if some time slot in this sub-district is used to the MBMS business of SFN network, can issue these time slots and scrambling code information thereof after setting up so in the system information block 5 (sib5) of system broadcasts.In view of scrambler resource in the TD-SCDMA system less, so when not having MBMS professional within a certain period of time, may need to discharge the time slot scrambler resource that it takies, yet existing 3GPP agreement does not provide the method that discharges the professional corresponding time slot scrambler of MBMS in the SFN network as required.
With reference to shown in Figure 1, be the scrambler resource collocation method flow chart of existing MBMS business.This method may further comprise the steps:
Step 101:RNC (Radio Network Controller, radio network controller) sends the sub-district to NodeB (Node B) and sets up request message, carries the scrambling code information of MBMS service needed configuration in described request message;
Step 102:NodeB returns the sub-district to RNC and sets up response, MBMS scrambler configuration successful;
Step 103:NodeB issues broadcast to user terminal, comprises the time slot and the scrambling code information thereof of configuration MBMS business in the described broadcast;
Step 104: discharge the scrambler resource of MBMS business if desired, then RNC sends the sub-district deletion request message to Node B, comprises the scrambler of the MBMS business that needs discharge in the described message;
After step 105:Node B receives this message, send sub-district deletion response message to RNC, the professional corresponding scrambler of MBMS is released.
According to the scrambling code collocation method of the MBMS business of existing SFN network, if the professional shared scrambler of MBMS is different with the scrambler of former sub-district, the scrambler resource of MBMS business just can only discharge by deleting the sub-district when the MBMS service ending so.Change if former sub-district is used for the scrambler of general service, can influence all users under the whole sub-district, by the deletion sub-district, rebuilding the sub-district then, to reconfigure scrambler be rational; But the MBMS service-user that only relates to part SFN network during the MBMS service ending, for the professional shared scrambler resource of corresponding time slot of the MBMS that discharges the SFN network deletion of whole sub-district being rebuild just seems is not quite reasonable.Generally speaking, about the collocation strategy and the imperfection of the MBMS business time-slot scrambler of SFN network, can't satisfy actual application demand in the existing 3GPP agreement.

Present embodiment RNC is that the concrete steps that the MBMS business is set up common cell sign under the SFN pattern are:
Step 201:RNC sends Common transport channel to Node B and sets up request message, sets up the professional corresponding auxilliary Common transport channel SCCPCH of MBMS under the SFN pattern;
Step 202:NodeB replys common signal channel to RNC and sets up response message, finishes the foundation of the SCCPCH of the professional correspondence of MBMS under the SFN pattern;
Step 203:RNC sends the Common transport channel reconfiguration request message to Node B, comprises in the message that the professional corresponding common cell of MBMS identifies the scrambling code information of place time slot;
After step 204:NodeB finishes configuration, reply successful Common transport channel reconfiguration response message and give RNC;
Step 205:NodeB issues broadcast to user terminal, comprises the time slot and the scrambling code information thereof of configuration MBMS business in the described broadcast.
Specifically, when the MBMS service conversation began after the sub-district is set up, RNC at first set up flow process by the Common transport channel of Iub mouth and sets up the professional needed SCCPCH channel of MBMS.
By above step 203 to step 205 as can be known, the configuration of scrambling code information is reshuffled flow process by Common transport channel and is finished, for instance, for example need on 2,3,4,5 time-slot code channels on 2010.8 carrier frequency, launch the MBMS business, so in the reconfiguration request message of Fa Songing, the UARFCN value of corresponding MBMS SFNTimeslot Scamble Ind is 10054, and Time Slot LCR is respectively 2,3,4,5, and corresponding scrambler resource assignment is given Time Slot Parameter ID.
After NodeB finishes the foundation of common cell sign common cell id under the SFN pattern, receiver can obtain these relevant configuration information of MBMS by the system broadcast message of monitoring sib5, has so far just finished the configuration feature of SFN MBMS business time-slot scrambler.
Present embodiment RNC be the concrete steps of the professional change of MBMS scrambler configuration under the SFN pattern details are as follows, wherein, described change comprises three kinds of situations: one, for the MBMS business reconfigures scrambling code information, thereby the pairing scrambling code information of release portion MBMS business; Two, the professional pairing common cell sign of deletion MBMS, the professional pairing scrambling code information of release portion MBMS; Three, the professional pairing common cell sign of the whole MBMS of deletion discharges the professional pairing scrambling code information of whole MBMS.
Present embodiment will be described in detail as follows respectively the above three kinds of situation, logically not constitute a complete explanation but this explanation does not influence present embodiment.
One, reconfigures scrambling code information for the MBMS business.
When scrambler resource is in short supply, need to discharge the professional time slot corresponding scrambler resource of a part of MBMS.Pass through O﹠amp; M (Operation and Maintenance, operation and maintenance) trigger to discharge Common transport channel and reshuffles flow process, finishes the reconfiguring of time slot scrambler of MBMS business.
Reconfigure the professional time slot corresponding scrambler resource of MBMS if desired, then the new time slot configuration with the cell ID correspondence fills in the Common transport channel reconfiguration request message just passable.Specifically, reconfigure in the following steps that scrambling code information is embodied in present embodiment shown in Figure 2 for the MBMS business:
Step 206:RNC sends the Common transport channel reconfiguration request message to Node B, comprises in the message that RNC is which time slot of sub-district is reshuffled the common cell sign;
Step 207:NodeB receives after the reconfiguration request, is configured according to common cell identifying resource new in the message, replys successful response message to RNC after finishing;
Step 208:NodeB issues broadcast to user terminal, comprises the time slot and the scrambling code information thereof of reshuffling the MBMS business in the described broadcast.
For instance, for example emission MBMS business on 2,3,4,5 time-slot code channels on original 2010.8 carrier frequency has been used 2 cover scramblers respectively, the corresponding cover Midamble1 of 2,3 time slots, the corresponding another set of Midamble2 of 4,5 time slots.Need to discharge the scrambler Midamble1 of 2,3 time slots now, the unified Midamble2 that uses of 2,3,4,5 time slots.RNC is in the reconfiguration request message that sends to NodeB so, and corresponding 2,3 time slot Time Slot Parameter ID values also are Midamble2, and the carrier frequency information UARFCN value of 2,3,4,5 time slot correspondences still is 10054.
Two, the professional pairing common cell sign of deletion MBMS, the professional pairing scrambling code information of release portion MBMS.In order to achieve this end, the content of the step 206 of present embodiment and step 207 can change to some extent.
Wherein, step 206 can for: send the common signal channel reconfiguration request message by RNC to NodeB, do not comprise the professional corresponding common cell sign of the MBMS that will delete in the described reconfiguration request message;
Accordingly, step 207 is: NodeB only is configured the common cell sign that not have deletion, then is equivalent to NodeB and has deleted common cell sign on the corresponding time slot, carry out described operation after, NodeB reshuffles response to RNC transmission Common transport channel;
Step 208:NodeB issues broadcast to user terminal, comprises the time slot and the scrambling code information thereof of the MBMS business of reshuffling in the described broadcast.
It is the concrete steps of the professional deletion of MBMS common cell sign under the SFN pattern that above step has constituted RNC.
For instance, for example, emission MBMS business on 2,3,4,5 time-slot code channels on original 2010.8 carrier frequency has been used 2 cover scramblers respectively, the corresponding cover Midamble1 of 2,3 time slots, the corresponding another set of Midamble2 of 4,5 time slots.Need to discharge the common cell sign of 2,3 time slots now.RNC is in the reconfiguration request message that sends to NodeB so, and MBMS SFN Timeslot ScambleInd only fills in 4,5 gap informations, and Time Slot Parameter ID value is Midamble2, and carrier frequency information UARFCN value is 10054.
Three, the professional pairing common cell sign of the whole MBMS of deletion discharges the professional pairing scrambling code information of whole MBMS.
The present invention is by the Common transport channel delete procedure, and the common cell of deletion MBMS business time-slot correspondence identifies.After the MBMS service ending, when needing to discharge the scrambler resource of whole SFN MBMS business time-slot, RNC sends the Common transport channel deletion request message to NodeB, and the professional corresponding common signal channel of deletion SFN MBMS discharges the professional pairing scrambling code information of whole MBMS.Specifically, the step 209 that is embodied in present embodiment shown in Figure 2 is to step 210, and is as follows:
Step 209:RNC sends the Common transport channel deletion request message to NodeB, discharges the professional corresponding common cell sign of MBMS in the SFN network;
After the common signal channel of step 210:NodeB deletion correspondence, send common signal channel deletion response to RNC.
After NodeB successfully deletes the corresponding Common transport channel SCCPCH of SFN MBMS business, reply successful Common transport channel deletion response, just finished the release function of the time slot scrambler of whole MBMS business under the SFN pattern to RNC.
Preferred embodiment two:
In the present embodiment, RNC and NodeB set up process by Common transport channel, finish the resource distribution of the common cell sign under the SFN pattern; By the Common transport channel reconfiguration course, finish the resource modifying and the release of the common cell sign under the SFN pattern.
Present embodiment with the difference of preferred embodiment one is: finish the foundation that the professional corresponding common cell of MBMS identifies in the process setting up of Common transport channel.And preferred embodiment one is after Common transport channel is set up, and finishes the foundation that the professional corresponding common cell of MBMS identifies by the Common transport channel reconfiguration course.Like this, the Common transport channel SCCPCH that execution mode two takies in the MBMS business carries out the configuration of time slot scrambler when setting up, and does not need to initiate a Common transport channel again and reshuffles the time slot scrambler configuration that flow process is finished the MBMS business specially.
The process of present embodiment comprises: 1) the RNC Common transport channel that sends to Node B is set up in the request message, is the common cell sign common cell id configuration scrambler resource of MBMS business under the SFN pattern; 2) after Node B receives this message, send Common transport channel to RNC and set up response message, finish the scrambler configuration of MBMS business; 3) RNC sends in the Common transport channel reconfiguration request message of Node B, for the common cell sign of MBMS business under the SFN pattern is revised or the release scrambler resource; 4) after Node B receives this message, send the Common transport channel reconfiguration response message to RNC.
It is identical with execution mode one to add information unit in the Common transport channel reconfiguration request message, need set up at Common transport channel simultaneously and add the shared time slot scrambling code information of the professional corresponding SCCPCH of MBMS in the request message, as shown in table 2.Under auxiliary publish control physical channel (Secondary CCPCHs), add the indication information (MBMS SFN Timeslot ScambleInd) of MBMS SFN time slot scrambler, content comprises scrambler (Time Slot Parameter ID), place time slot (Time Slot LCR) and carrier frequency information (UARFCN), and the information content is consistent with execution mode one.

In the present embodiment, RNC is that the professional concrete steps of setting up, reshuffling and delete common cell sign common cell id of MBMS are under the SFN pattern:
Step 301:RNC sends Common transport channel to Node B and sets up request message, comprises the professional corresponding common cell sign of MBMS common cell id in the described request message;
Step 302:NodeB replys common signal channel to RNC and sets up response message, finishes the foundation that the professional corresponding common cell of MBMS identifies under the SFN pattern;
Step 303:NodeB issues broadcast to user terminal, comprises the time slot and the scrambling code information thereof of configuration MBMS business in the described broadcast;
Specifically, when the MBMS service conversation began after the sub-district is set up, RNC at first set up flow process by the Common transport channel of Iub mouth and sets up the professional needed SCCPCH channel of MBMS.RNC is setting up in the request message to NodeB transmission Common transport channel, directly carries the professional time slot corresponding scrambling code information of SFN MBMS.
For instance, for example need on 2,3,4,5 time-slot code channels on 2012.4 carrier frequency, launch the MBMS business, the Common transport channel of Fa Songing is set up in the request message so, the UARFCN value of corresponding MBMS SFNTimeslot Scamble Ind is 10062, Time Slot LCR is respectively 2,3,4,5, and corresponding scrambler resource assignment is given Time Slot Parameter ID.
After NodeB finishes foundation, reply successful Common transport channel and set up response message to RNC.So far just finished the configuration feature of SFN MBMS business time-slot scrambler.
When scrambler resource is in short supply, need to discharge a part of FSN MBMS time slot corresponding scrambler resource.Identical with execution mode one, pass through O﹠amp; M triggers the release Common transport channel and reshuffles flow process, finishes reconfiguring of FSN MBMS time slot scrambler.Revise FSN MBMS time slot corresponding scrambler resource if desired, then new scrambling code information is filled in the Common transport channel reconfiguration request message just passable.
Step 304:RNC sends the Common transport channel reconfiguration request message to Node B, comprises in the message that RNC is which time slot of sub-district is reshuffled the common cell sign;
Step 305:NodeB receives after the reconfiguration request, indicates resource according to common cell new in the message and is configured, and replys successful response message to RNC after finishing;
Step 306:NodeB issues broadcast to user terminal, comprises the time slot and the scrambling code information thereof of reshuffling the MBMS business in the described broadcast;
For instance, for example emission MBMS business on 2,3,4,5 time-slot code channels on original 2012.4 carrier frequency has been used 2 cover scramblers respectively, the corresponding cover Midamble1 of 2,3 time slots, the corresponding another set of Midamble2 of 4,5 time slots.Need to discharge the scrambler Midamble2 of 4,5 time slots now, the unified Midamble1 that uses of 2,3,4,5 time slots.RNC is in the reconfiguration request message that sends to NodeB so, and corresponding 4,5 time slot Time Slot Parameter ID values also are Midamble1, and the carrier frequency information UARFCN value of 2,3,4,5 time slot correspondences still is 10062.NodeB receives after the reconfiguration request, is configured according to scrambler resource new in the message, replys successful response message to RNC after finishing.
Be the method for the time slot deletion common cell of sub-district sign, also can still send the common signal channel reconfiguration request message to NodeB and start by RNC.
At this moment, step 304 is: RNC sends the common signal channel reconfiguration request message to NodeB, does not comprise the professional corresponding common cell sign of the MBMS that will delete in the described reconfiguration request message;
Accordingly, step 305 is: NodeB only is configured the common cell sign that not have deletion, after NodeB deletes common cell sign on the corresponding time slot, to RNC transmission Common transport channel reconfiguration response message.
For instance, for example emission MBMS business on 2,3,4,5 time-slot code channels on original 2010.8 carrier frequency has been used 2 cover scramblers respectively, the corresponding cover Midamble1 of 2,3 time slots, the corresponding another set of Midamble2 of 4,5 time slots.Need to discharge the common cell sign of 2,3 time slots now.RNC is in the reconfiguration request message that sends to NodeB so, and MBMS SFN Timeslot ScambleInd only fills in 4,5 gap informations, and Time Slot Parameter ID value is Midamble2, and carrier frequency information UARFCN value is 10054.
Present embodiment is identical with embodiment one, by the Common transport channel delete procedure, and the common cell sign of deletion MBMS business time-slot.After the MBMS service ending, when needing to discharge the time slot scrambler resource of whole SFN MBMS business time-slot, RNC sends the Common transport channel deletion request message to NodeB, the professional corresponding common signal channel of deletion SFN MBMS.
Step 307:RNC sends the Common transport channel deletion request message to NodeB, discharges the professional corresponding common cell sign of MBMS in the SFN network;
After the common signal channel of step 308:NodeB deletion correspondence, send common signal channel deletion response to RNC.
After NodeB successfully deletes the corresponding SCCPCH of SFN MBMS business, reply successful Common transport channel deletion response, just finished the release function of the time slot scrambler of whole MBMS business under the SFN pattern to RNC.
The present invention is by adding information field in the Common transport channel reconfiguration message, reshuffle configuration, modification and the deletion action that flow process is finished the professional scrambler resource of MBMS by means of Common transport channel, can the MBMS business time-slot scrambler that needs discharge be discharged, conserve system resources, satisfy application demand, when needs discharge the scrambler resource of whole MBMS business, carry out the release of scrambler resource simultaneously by the deletion Common transport channel, more reasonable with respect to existing method.
Certainly, the foregoing description is not the further qualification to technical solution of the present invention, and any those of ordinary skill in the art replace or corresponding deformation the technology of the present invention feature being equal to of being done, still within protection scope of the present invention.
