Description
Technical field
The present invention relates generally to wireless communication field, more specifically, relates to a kind of emission mode selection/switching mechanism, a kind of radio configuration setting device, a kind of multi-community/multimedia cooperation device and a kind of emission mode selection/switching method.
Background technology
At 3GPP TS36.300 (3GPP TS36.300VO.4.0, " E-UTRA and E-UTRANOverall de scription Stage2 ", in January, 2007) in, two kinds of MBMS emission modes that are used among the E-UTRA/E-UTRAN have been defined: emission of many sub-districts and the emission of single sub-district.Whether the main distinction between these two kinds of emission modes is: utilize SFN (single frequency network) operation to eat dishes without rice or wine merging naturally of radiofrequency signal in transmission.The emission of many sub-districts utilizes the SFN operation, by merging the signal from other sub-districts, improves cell-edge performance.But, the synchronization mechanism that the SFN action need is extra, and on MTCH (MBMS (multimedia broadcast multi-broadcasting business) point multipoint message traffic channel), need bigger transmitting power, with the coverage cell edge.The emission of single sub-district is with similar at the unicast service of some particular service demands and less user situation.The overall performance of single sub-district emission may be not as the emission of many sub-districts, and the emission of still single sub-district can be adopted the QoS (service quality) that improves at unique user the MBMS business as HARQ technology such as (mixing automatic repeat requests).
The emission mode of E-MBMS (MBMS of evolution) is determined by traffic performance, network design situation and user distribution situation.In order further to improve MBMS performance and radio resource efficiency, in the session cycle, the emission mode of MBMS business will dynamically change according to actual state.
Here, will describe the single sub-district emission of E-MBMS deployment scenario, and emission mode selection and switching judging will be discussed.
The essential characteristic of E-MBMS single sub-district emission is: do not need the signal from other sub-districts is merged.But this does not also mean that in many cell MBMSs retaining zone, can not use the emission of single sub-district.The deployment of E-MBMS single sub-district emission and the physical layer synchronization state of eNB (base station of evolution) are irrelevant.No matter whether eNB is synchronous, all can use the single sub-district of E-MBMS emission mode.
In addition, single sub-district is launched and is not meant that the emitting area with the MBMS business only is confined in the cell coverage area.Some adjacent coverage cell also can be utilized single sub-district emission mode.In this case, carry out to the sub-district emission of single sub-district one by one, and each sub-district is carried out the single sub-district emission of himself respectively.
According to the relevant discussion (R3-061973 " eMBMSdefinition ", in November, 2006) of E-MBMS SFN zone definitions, except that the SFN zone, the emission of single sub-district can be deployed in Anywhere.Fig. 1 shows the example of the single sub-district emission of E-MBMS deployment scenario.
Some rules that the emission of single sub-district is disposed to E-MBMS are summarized as follows:
-single sub-district emitting area can be arranged in the sub-district (sub-district shown in the Reference numeral 1) of many cell MBMSs retaining zone;
-single sub-district emitting area can be arranged in the outer sub-district (sub-district shown in the Reference numeral 2) of many cell MBMSs retaining zone;
-single sub-district emitting area cannot be arranged in the sub-district in SFN zone;
-single sub-district emitting area can be arranged in the sub-district in the maximum SFN zone except that the SFN zone, but, in maximum SFN zone, adopt the sub-district of single sub-district emission not have adjacent boundary to each other, that is, these sub-districts should be (sub-districts shown in the Reference numeral 3) separated from one another;
-single sub-district emitting area can be arranged in the sub-district (sub-district shown in the Reference numeral 4) of SFN protection zone;
-single sub-district emitting area needn't only be confined in the cell coverage area, also can be the continuous overlay area (zone shown in the Reference numeral 5) of several sub-districts;
-a plurality of sub-districts of belonging to single sub-district emitting area can be the sub-districts of same eNB, also can not be; And
-at a MBMS business, can there be a plurality of single sub-districts emitting area simultaneously.

Embodiment
To a preferred embodiment of the present invention will be described in detail, having omitted in the description process is unnecessary details and function for the present invention with reference to the accompanying drawings, obscures to prevent that the understanding of the present invention from causing.
1. emission mode is selected
Emission mode is and the relevant notion of RAN (wireless access network), is one of radio configuration parameter at the E-MBMS business.Functional definition (R3-062015 " LS on LTE-MBMS Discussions in RAN3 " according to MCE (the many sub-district/multicast coordination entity of Multi-cell/MulticastCo-ordination Entity), in November, 2006), emission mode is selected and can be carried out in MCE.A service conversation (Session) can have single sub-district emission mode and many sub-districts emission mode simultaneously in different emitting areas.Some cell coverage areas among the SA (coverage) can adopt single sub-district emission mode, and other cell coverage areas can adopt many sub-districts emission mode.
When MCE when SAE GW (System Architecture Evolution gateway) receives MBMS service conversation/updating message, MCE starts the radio configuration set handling and service dispatching is handled, select comprising emission mode, and the final result that emission mode is selected is included in the radio configuration parameter of this MBMS business and sends to related eNB.
The principal element that influences the emission mode selection comprises:
-coverage (SA) definition;
-network design situation comprises the cell neighboring relation of each sub-district and the SFN operational capacity of each sub-district of determining by maximum SFN zone definitions; And
-by counting the MBMS user distribution situation of (Count ing) result indication.
SA has defined the maximum region of this professional emission, has only those sub-districts that are positioned at the zone that SA and maximum SFN zone overlap each other could adopt many sub-districts emission mode.But, also need to judge the adjacency state of these sub-districts by cell neighboring relation and count results.
Count results reflects whether there is at least one user in this sub-district.Do not exist user's sub-district not need to launch this business datum, and have influence on the connectivity of other minizones.
The sub-district that is positioned at the overlapping region in SA and maximum SFN zone and is connected with each other is many sub-districts of MBMS service selection emission mode for this reason.These sub-districts also constituted should business the SFN zone, and in the maximum SFN zone, may have a plurality of SFN zones that should business.Be positioned at the overlapping region in SA and maximum SFN zone but single sub-district emission mode can only be adopted in disjunct each other other sub-districts.
Be positioned at SA but sub-district beyond the overlapping region in SA and the maximum SFN zone single sub-district of MBMS service selection emission mode for this reason.
According to above analysis, need to keep some as can be known among the MCE and be used for the information that emission mode is selected, comprise neighbor cell list, maximum SFN zone and the sub-district map information of SA and sub-district map information, each sub-district.
Fig. 2 shows the schematic diagram of selecting relevant basic structure among the MCE with emission mode.
Fig. 2 shows SAE AW100, MCE200 and eNB300, and shows basic structure relevant with emission mode selection/switching among the MCE200.MCE200 comprises that memory 210 and radio configuration are provided with module 220.Radio configuration is provided with module 220 and comprises emission mode selection/handover module 230, and, trigger the emission mode of emission mode selection/handover module 230 and select to handle or the emission mode hand-off process according to MBMS session initiation/updating message of receiving from SAE GW100 or from the results messages of counting again that eNB300 receives.Memory 210 is used to preserve the information of neighbor cell list, maximum SFN zone and sub-district mapping relations of mapping relations information, each sub-district of SA and sub-district, as the auxiliary initial conditions of emission mode selection/switching.Radio configuration is provided with the most definite emission mode of module 220 and is notified to corresponding eNB300.
Emission mode selection/handover module 230 comprises that overlapping region determination module 2300, subdistrict position determination module 2310, sub-district distribution situation determination module 2320 and emission mode determine/judge module 2330.When radio configuration is provided with module 220 and receives MBMS session initiation/updating message, overlapping region determination module 2300 is determined the SA of this MBMS business and the overlapping region of maximum SFN according to the SA and the mapping relations information of sub-district and the information of maximum SFN zone and sub-district mapping relations that are kept in the memory 210.Subdistrict position determination module 2310 is at each sub-district in the SA, determine whether this sub-district is in by in the overlapping region determination module 2300 determined above-mentioned overlapping regions, be in the sub-district in the overlapping region and be not in sub-district in the overlapping region thereby the microzonation in the SA is divided into.Subdistrict position determination module 2310 will not be in sub-district in this overlapping region and directly is notified to emission mode and determines/judge module 2330, and emission mode determines/and judge module 2330 is at these sub-districts, selects single sub-district emission mode.The cell notification that subdistrict position determination module 2310 will be in this overlapping region is given sub-district distribution situation determination module 2320.Sub-district distribution situation determination module 2320 is according to count results message and the neighbor cell list that is stored in each sub-district in the memory 210 from eNB300, define the distribution situation of the sub-district of users interest, what thereby users interest will be arranged divides into non-adjacent sub-district (not having the sub-district of users interest adjacent with other) and abutting subdistrict (having the sub-district of users interest adjacent with other) for a short time, and the information of non-adjacent sub-district and abutting subdistrict is notified to emission mode determines/judge module 2330.Emission mode determines/judge module 2330 is at non-adjacent sub-district, and select single sub-district emission mode, and, select many sub-districts emission mode at abutting subdistrict.At last, radio configuration is provided with module 220 selected emission mode is notified to corresponding eNB300 (being in each corresponding sub-district).
In the process that this MBMS business is carried out, eNB300 will periodically send again count results message and reflect distribution situation to the professional users interest of this MBMS.When sub-district distribution situation determination module 2320 receives again count results message, according to message of count results again and the neighbor cell list that is stored in each sub-district in the memory 210 from eNB300, redefine the distribution situation of the sub-district of users interest, thereby the sub-district that users interest will be arranged is reclassified as non-adjacent sub-district and abutting subdistrict, and the information of non-adjacent sub-district and abutting subdistrict is notified to emission mode determines/judge module 2330.Emission mode determines/judge module 2330 is at non-adjacent sub-district, and select single sub-district emission mode, and, select many sub-districts emission mode at abutting subdistrict.After this, emission mode determines/judge module 2330 is at each sub-district, judges whether emission mode of this time selecting is identical with the emission mode that is using before.If at a certain sub-district, this time the emission mode of selecting is identical with the emission mode that is using before, then needn't switch emission mode, therefore, does not need to send emission mode to the eNB300 corresponding with this sub-district and switches message; If at a certain sub-district, this time emission mode of selecting is different with the emission mode that is using before, then needs to switch emission mode, and therefore, radio configuration is provided with module 220 emission mode of this selection is notified to the eNB300 corresponding with this sub-district.
Concrete emission mode selection course at a MBMS business is as shown described in 3.
At step S301, the radio configuration among the MCE200 is provided with module 220 and receives the processing procedure that MBMS session initiation/updating message has triggered the emission mode selection.
At step S302, the information of the SA that MCE200 (overlapping region determination module 2300) preserves according to wherein (memory 210) and the mapping relations information of sub-district and maximum SFN zone and sub-district mapping relations are determined the overlapping region of this professional SA and maximum SFN.
At step S303, the counting process of execution cycle property is handled in the sub-district in SA zone, and whether the result of counting is used for judging has in this sub-district this business users interest.
The periodic follow-up New count of then attaching most importance to of counting process, Ji Shuo results messages is the trigger condition (will be described with reference to figure 4 after a while) of carrying out the emission mode hand-off process again.
At step S304, MCE200 (subdistrict position determination module 2310) judges the relation of the overlapping region of the sub-district of the SA that this is professional and maximum SFN.For the sub-district that is not in this overlapping region, the direct execution in step S308 of MCE200, (emission mode is determined/judge module 2330) selects the emission mode of these sub-districts is single sub-district emission mode.For the sub-district that is in this overlapping region among those SA, MCE200 execution in step S305 carries out the result treatment process to counting/counting again.
At step S305, MCE200 (sub-district distribution situation determination module 2320) carries out counting/processing of counting again.
For a MBMS session initiation/updating message that newly receives, the processing that begins to count.MCE200 determines whether the sub-district in the overlapping region of the sub-district of these SA and maximum SFN has this business users interest.Do not have user's interested sub-district for those, do not need to carry out the transmission of this MBMS business datum, and then have influence on the connecting property of other sub-districts.
Can trigger the judgment processing that emission mode switches for the results messages of counting again, equally also be to determine the distribution situation (after a while, will with reference to figure 4 be described) of user interested in the sub-district.
At step S306, MCE200 (sub-district distribution situation determination module 2320) judges the distribution situation that the users interest sub-district is arranged in the overlapping region, with determine these sub-districts in abutting connection with situation.If these sub-districts are adjacent to each other, MCE200 execution in step S307 then, the emission mode of determining these sub-districts is many sub-districts emission mode.Otherwise MCE200 execution in step S308, the emission mode of selecting these sub-districts are single sub-district emission mode.
At step S307, it is many sub-districts emission mode that MCE200 (emission mode is determined/judge module 2330) selects emission mode.
At step S308, it is single sub-district emission mode that MCE200 (emission mode is determined/judge module 2330) selects emission mode.
At step S309, the radio configuration among the MCE200 is provided with module 220 selected emission mode is notified to corresponding eNB300.
At last, at step S310, select processing to finish according to emission mode of the present invention.
For many sub-districts emission mode, only adopt PTM (putting multiple spot)) emission.If many sub-districts emission mode is selected in the MCE decision, then MCE will use " label (Label) " value to determine relevant RB (radio bearer) configuration of this business.But,, can adopt PTP (point-to-point) and PTM (putting multiple spot) emission for single sub-district emission mode.The RB configuration of MCE and uncertain single sub-district emission mode business, and just notified at this service selection single sub-district emission mode to relevant eNB, and select PTP or PTM and RB configuration according to actual state by eNB self.
2. emission mode switches
During a session, because user mobility and ON/OFF (ON/OFF) operation, the distribution of MBMS service-user may change.This will have influence on the connectivity characteristic of sub-district.In order to improve the level of resources utilization, need to consider that emission mode switches, because the emission of single sub-district will utilize than manying sub-district emission less resources.
Similar with above-mentioned emission mode selection, in the emission mode switching judging, need equally to consider above-mentioned whole factors, but the trigger condition that emission mode switches is to count (re-counting) result again.When eNB obtained again count results, eNB should send to MCE with this result.Then, MCE starts the processing of emission mode switching judging.The basic procedure of switching judging selects flow process identical with emission.If switching judging result is identical with preceding emission mode selection, then MCE needn't take any operation.Otherwise MCE need be provided with parameter with relevant radio configuration with the emission mode of newly selecting and be notified to relevant eNB.
Fig. 4 shows the basic procedure at the emission mode hand-off process of a MBMS business.
Represent with identical Reference numeral that with the step that Fig. 3 is similar the step different with Fig. 3 goes out with thick frame wire frame.
At step S303, in the process that this MBMS business is carried out, the counting process of execution cycle property is handled in the sub-district in SA zone, because the periodicity of counting process repeats, periodically produces the results messages of counting again; As MCE200 (sub-district distribution situation determination module 2320) when receiving again count results message, trigger the emission mode hand-off process.
At step S305, MCE200 (sub-district distribution situation determination module 2320) carries out the processing of counterweight New count, redefines the distribution situation of user interested in the sub-district.
At step S306, MCE200 (sub-district distribution situation determination module 2320) rejudges the distribution situation that the users interest sub-district is arranged in the overlapping region, determine these sub-districts in abutting connection with situation.If these sub-districts are adjacent to each other, MCE200 execution in step S307 then, the emission mode of determining these sub-districts is many sub-districts emission mode.Otherwise MCE200 execution in step S308, the emission mode of selecting these sub-districts are single sub-district emission mode.
At step S307, it is many sub-districts emission mode that MCE200 (emission mode is determined/judge module 2330) selects emission mode.
At step S308, it is single sub-district emission mode that MCE200 (emission mode is determined/judge module 2330) selects emission mode.
At step S401, MCE200 (emission mode is determined/judge module 2330) compares emission mode and the original emission mode of newly selecting at each sub-district.
If at a certain sub-district, the new emission mode of selecting is different with original emission mode, then at step S402, MCE200 (emission mode is determined/judge module 2330) determines to need to switch emission mode, emission mode result with new selection substitutes original emission mode, and at step S309, the radio configuration among the MCE200 is provided with the emission mode that module 220 will newly select and is notified to the eNB300 corresponding with this sub-district.
If at a certain sub-district, the new emission mode of selecting is identical with original emission mode, and then at step S403, MCE200 (emission mode is determined/judge module 2330) determines not need to switch emission mode, keep original emission mode, need not execution in step S309.
At last, at step S310, finish according to emission mode hand-off process of the present invention.
