When Fig. 4 is Resources allocation from synchronous sketch map between MBS radio resource manager and the main MBS radio resource manager;
Fig. 5 is from the synchronous sketch map between MBS radio resource manager and the main MBS radio resource manager when discharging resource; And
Fig. 6 is a sketch map of dividing the Radio Resource that is used for MBS in the descending sub frame.
Embodiment
For a SFN (Single Frequency Network that the network planning is good; Be called for short SFN); From the Radio Resource of descending sub frame, extract a part of Radio Resource and insert (as shown in Figure 6) as MBS; And be that unit carries out unified management to the Radio Resource that is used for MBS with MBS Zone, just there is a MBS radio resource manager in each MBS Zone, be used for MBS Radio Resource unified management in this MBS Zone scope.For there being the overlapping situation of MBS Zone, how to share the problem that this part is used as the MBS Radio Resource of MBS access with regard to the MBS radio resource manager that has two MBS Zone.
The present invention proposes the problem that two kinds of methods solve the resource coordination management between this MBS Zone with overlapping relation.
Method one: the coordinated management of the MBS Radio Resource that the radio resource manager (being respectively A and B) with two MBS Zone of overlapping relation is realized through the MBS Radio Resource sharing synchronously.MBS radio resource manager A is to accomplish through the affirmation of radio resource manager B to the management of MBS Radio Resource.
Wherein, several kinds of situation below all can trigger between the MBS radio resource manager of two MBS Zone synchronously:
1) the MBS radio resource manager of certain MBS Zone is reserved, is distributed or the deletion resource.
2) timing cycle is synchronous.
3) active request.The MBS radio resource manager of certain MBS Zone can be initiatively obtains the situation that takies of the other side MBS Radio Resource to the MBS radio resource manager request that has a MBS Zone of overlapping relation with it.
For reduction situation 1) in the MBS radio resource manager between synchronizing frequency, can adopt following measure:
1) professional for the MBS real-time, that fixed-bandwidth demand and duration are arranged, can be the disposable distribution of the Radio Resource of this service needed.
2) professional for MBS short, burst; Can reserve a part of Radio Resource to the MBS radio resource manager of each MBS Zone; Short like this, burst service resource can directly be used for that part of Radio Resource that this MBS Zone reserves, and therefore can avoid synchronous to business short, burst.
3) if MBS business short, burst is not used MBS Radio Resource reservation mode; And employing source synchronous mode; If then the MBS Radio Resource becomes the distribution of work first; And professional transmit finish after, immediately this part Radio Resource is not changed to and idlely synchronously has the MBS radio resource manager of the MBS Zone of overlapping relation, but wait a timer of presetting just synchronous then to other; If preset timer then before, have new weak point, burst service, then still can use this a part of Radio Resource, and reset timer.
Wherein, the synchronizing process for newly-increased MBS program distribution Radio Resource comprises following steps:
When one of them radio resource manager A by after the newly-increased MBS program of linchpin MBS Zone reserves Radio Resource, need send the MBS Radio Resource to another one radio resource manager B and reserve report message, report MBS Radio Resource that its is reserved.
After radio resource manager B received this message, then the branch situation was handled.Situation 1: if current this reserved resource that do not use of B, the MBS Radio Resource that then returns to A is reserved in the report acknowledge message indication with a success.Situation 2: if B need use this reserved resource; Then will adjudicate this reserved resource according to pre-configured strategy is that A uses or uses as B; If the result of judgement is used by A for this reserved resource, the indication with a success is reported in the acknowledge message in the MBS Radio Resource reservation of then returning to A; If the result of judgement is used by B for this reserved resource, the indication with a failure is reported in the acknowledge message in the MBS Radio Resource reservation of then returning to A.
After radio resource manager A receives that the MBS Radio Resource is reserved the report acknowledge message, handle according to indicating bit.If be designated as success, then be indicated as newly-increased MBS program reserved resource success; If indicating bit is failure, then show this reserved resource failure.If also have remaining MBS Radio Resource to use, then radio resource manager A can repeat said process.
The MBS Radio Resource is reserved report message can have following several kinds of modes.Mode 1 comprises the MBS resource identification of total reservation.Mode 2, if be the multiple programs reserved resource, then MBS Radio Resource reservation report message can comprise program marker and the indication of corresponding program reserved resource.Mode 3, the processing when clashing for ease of the MBS Radio Resource of MBS Zone with overlapping relation, the MBS Radio Resource is reserved the reserved resource indication that report message can comprise program marker, program priority and corresponding program.Mode 4, if be the multiple programs reserved resource, then the MBS Radio Resource is reserved report message and can be included as the mark whether the multiple programs reserved resource is bound.
The MBS Radio Resource is reserved the report acknowledge message can have following several kinds of modes.Mode 1 comprises and confirms result's indication, confirms that the result is successfully or fails; If reserved resource clashes, then radio resource manager B can utilize the program priority in the MBS allocation of radio resources report message to judge whether this reserved resource is successful.Mode 2; If the MBS Radio Resource is reserved the reserved resource mark that report message comprises multiple programs mark and corresponding program; Then the MBS Radio Resource is reserved the mark that the report acknowledge message can only comprise resource reservation success program marker or resource reservation failure program, perhaps comprises each program marker in the MBS resource reservation report message and reserves the mark of success or not.Mode 3; If the MBS Radio Resource is reserved the reserved resource mark that comprises multiple programs mark and corresponding program in the report message; If the whole reservation confirmation successes of all program resources; Then the MBS Radio Resource is reserved the report acknowledge message only needs an affirmation successfully to indicate, if the whole reservation confirmation failures of all program resources, then the MBS Radio Resource is reserved the report acknowledge message only needs one to confirm the failure indication.Mode 4; If it is the multiple programs reserved resource that the MBS Radio Resource is reserved report message, include the mark whether the program resource binds simultaneously, if for binding; As long as there is a program resource reservation to confirm failure, then the MBS Radio Resource is reserved report message and is carried affirmation failure indication.
After receiving that the MBS Radio Resource is reserved the report acknowledge message, be failure, then need reserved resource again if confirm the result; If just partial programme resource reservation failure, and the program resource do not need to bind, and then only needs get final product for failure program reserved resource again.
Reserve in the report message at the MBS Radio Resource, the MBS resource mark of reservation can have multiple expression mode.After the resource reservation success, the MBS radio resource manager can be given the MBS in the MBS Zone professional framing functional module the resource reservation result notification.
Synchronizing process when wherein, discharging MBS program resource is following:
After normal release of MBS program resource of the MBS Zone that one of them radio resource manager A is had jurisdiction over, radio resource manager A need be to the resource mark of the synchronous MBS Radio Resource that discharges of B.But A has jurisdiction over after the MBS program resource of MBS Zone discharges in advance, need send the MBS Radio Resource to B and discharge report message, reports the MBS resource mark that it has discharged.
MBS radio resource manager B receives the resource mark of the MBS Radio Resource of the release in the MBS allocation of radio resources report message, thinks that this Radio Resource is current can use.Return MBS Radio Resource report acknowledge message for simultaneously MBS radio resource manager A.
Wherein, the MBS Radio Resource discharges the information that report message should comprise the MBS Radio Resource of current release at least.The information of the MBS Radio Resource that discharges has multiple mode.Mode 1: directly adopt to discharge program marker; The reserved resource that in MBS allocation of radio resources report message, can include program marker and corresponding program; After the MBS radio resource manager is received and discharged program marker, just know that corresponding MBS Radio Resource discharges.Mode 2: the MBS resource mark of directly carrying release.Mode 3: the mark of current existing MBS program, the program marker that does not have to occur means and needs to discharge.If be all to discharge, then existing MBS program marker number is 0.
Process when wherein, active request MBS Radio Resource is synchronous is following:
MBS radio resource manager A sends MBS wireless resource information request message to MBS radio resource manager B, and request B reports the resource information of its current MBS Radio Resource that takies.
MBS radio resource manager B sends MBS wireless resource information response message to MBS radio resource manager A.
MBS radio resource manager A returns MBS wireless resource information response confirmation message to MBS radio resource manager B.
Wherein, MBS wireless resource information response message should comprise at least that current this MBS radio resource manager has distributed and the resource mark of the MBS Radio Resource that using, or comprises the program marker and the corresponding resource mark of each program.
Timing cycle is meant that synchronously the MBS radio resource manager is initiatively to having the synchronous situation that himself takies the MBS Radio Resource of MBS Zone of overlapping relation with it.MBS radio resource manager A initiatively reports the process of its current MBS Radio Resource occupied information following to the MBS radio resource manager B that has an overlapping relation with it:
MBS radio resource manager A sends MBS wireless resource information response message to MBS radio resource manager B.
MBS radio resource manager B returns MBS wireless resource information response confirmation message to MBS radio resource manager A.
Wherein, MBS wireless resource information response message should comprise at least that current this MBS radio resource manager has distributed and the resource mark of the MBS Radio Resource that using or comprise the program marker and the corresponding resource mark of each program.
Source synchronous under above various situation is to be that example describes with two MBSZone with overlapping relation.In fact, the MBS radio resource manager is that the MBS radio resource manager that MBS Zone with its place has all MBS Zone of overlapping relation carries out synchronous synchronously the time.
Method two: in the radio resource manager (supposing to be respectively A and B) of two MBS Zone with overlapping relation, selecting one is main MBS radio resource manager, and remaining is from the MBS radio resource manager.The management of MBS Radio Resource is all accomplished on main MBS radio resource manager, from the MBS radio resource manager management of MBS Radio Resource is all accomplished through main MBS radio resource manager.When the MBS Radio Resource reserved or distributed to the MBS radio resource manager need, through applying for accomplishing to main MBS radio resource manager; During from MBS radio resource manager release MBS Radio Resource, also to notify main MBS radio resource manager.
Below several kinds of situation all can trigger from the MBS radio resource manager and send message to main MBS RRM:
1) having jurisdiction over MBS Zone from the MBS radio resource manager has new-programme to need distributing radio resource.
2) have jurisdiction over MBS Zone and discharge MBS program resource from the MBS radio resource manager after.
For reducing the synchronizing frequency between the principal and subordinate MBS radio resource manager, can adopt following three kinds of modes:
1) professional for the MBS real-time, that fixed-bandwidth demand and duration are arranged, main MBS radio resource manager can be the disposable distribution of the Radio Resource of this service needed.
2) for short, burst service; Can reserve a part of Radio Resource from the MBS radio resource manager to each; Therefore short, burst service like this Radio Resource can be avoided frequently to main MBS radio resource manager requests resource allocation business short, burst directly by distributing that part of Radio Resource of reserving from the MBS radio resource manager.
3) if short, burst service does not use reserved resource; And adopt the main MBS radio resource manager method of salary distribution equally; In the success of MBS allocation of radio resources; Short, burst MBS is professional transmit finish after, be not immediately this part Radio Resource to be changed to the free time to report to main MBS radio resource manager from the MBS radio resource manager, but just report after waiting a preset timer then; If preset timer then before, if having new weak point, MBS is professional in burst, then still can use this a part of Radio Resource, and reset timer.
When being had jurisdiction in the MBS Zone new-programme distributing radio resource, comprise following steps from the MBS radio resource manager:
Send MBS allocation of radio resources request message from the MBS radio resource manager to main MBS radio resource manager.
Main MBS radio resource manager is received behind the MBS allocation of radio resources request message of MBS radio resource manager transmission, is the program distribution Radio Resource of request; And bring radio resource manager through MBS allocation of radio resources response message from MBS with the allocation of radio resources result.
After receiving MBS allocation of radio resources response message from the MBS radio resource manager, return MBS allocation of radio resources response confirmation message for main MBS radio resource manager.
Wherein, MBS allocation of radio resources request message can have dual mode.Mode 1 is to the total bandwidth and the duration of all programs of request, must comprise total bandwidth and duration in mode 1 message.Mode 2 is to request needed bandwidth of each program and duration; Therefore mode 2 comprises the program marker of each program and the bandwidth and the duration of each program at least, the mark whether mode 2 can also increase the program priority flag and bind for the Radio Resource of each program distribution.
The MBS radio resource request message is adopted mode 1, and MBS allocation of radio resources response message should have the allocation result mark at least, and allocation result is labeled as success or failure, is successfully for allocation result, then need be with going up the resource mark of distributing.
To request mode 2, then MBS allocation of radio resources response message has following manner.Mode 1, to multiple programs, whether successful response message comprise program marker and resource allocation mark, if the successful program of resource allocation, then also will be with the resource mark that goes up to the MBS Radio Resource of this program distribution.Mode 2 if multiple programs distributes the program resource all to fail, also can be come mark with a total failure, and need not be to each program marker failure.Mode 3 if multiple programs distributes all successes of program resource, also can be come mark with a total success, is the MBS resource mark of all program distribution with going up then.Mode 4 to multiple programs and have the request of program bound flag, can only represent with a total mark whether successfully current resource allocation; Have only all program resource allocation successes, just have and distribute successful mark; As long as have the program resource allocation unsuccessful, then be with the resource allocation fail flag; To all program resource allocation case of successful, can use to all program distribution go out total MBS resource mark and represent, also can represent with the resource mark of the MBS Radio Resource of the correspondence of program marker and distribution thereof.
During from MBS radio resource manager release Radio Resource, comprise following steps:
Send the MBS Radio Resource from the MBS radio resource manager to main MBS radio resource manager and discharge report message.
After main MBS radio resource manager received that the MBS Radio Resource discharges report message, it is available now that mark discharges the MBS Radio Resource, gives simultaneously from the MBS radio resource manager and return MBS Radio Resource release report acknowledge message.
Wherein, the MBS Radio Resource discharges the MBS wireless resource information that report message should comprise current release at least.The MBS wireless resource information that discharges has multiple mode.Mode 1 directly adopts to discharge program marker, because main MBS radio resource manager knows that it is the resource information of this program distribution.Mode 2 is directly carried the MBS resource mark of release.Mode 3, the program marker of current existing MBS program, the program marker that does not have so to occur means and needs to discharge.If be all to discharge, then existing MBS program marker number is 0.
No matter adopting method one still is method two; According to the final framework of confirming of MBS (Multicast andBroadcast Service is called for short MBS), the position of MBS radio resource manager both can be positioned at BS; Also can be positioned at the gateway (ASNGateway is called for short AGW) of access service network.In addition, the MBS radio resource manager with two MBS Zone of overlapping relation possibly reside on the identical entity, also possibly reside on the different entities; If they reside on the identical entity, then can manage the MBS Radio Resource of MBS Zones with overlapping relation by a MBS radio resource manager, do not relate to synchronizing process.
In each MBS Zone, except the MBS radio resource manager of being responsible for the MBS RRM, (be called ownership MBS radio resource manager here), also have relaying MBS radio resource manager.When the synchronization message between two MBS radio resource managers can not be gone directly, then need relaying MBS radio resource manager relay synchronization message.Just adopt method for the moment, the MBS Radio Resource coordinated management that has between the MBS Zone of overlapping relation is to realize through ownership MBS radio resource manager separately; When adopting method two, have MBS Radio Resource coordinated management between the MBS Zone of overlapping relation and belong to the MBS radio resource manager through the principal and subordinate and realize.With reference to accompanying drawing, specify embodiment of the present invention below.
