Description

A kind of radio resource management method and radio network controller
Technical field
The present invention relates to communication technical field, relate in particular to a kind of radio resource management method and radio network controller.
Background technology
TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, TD SDMA) be a kind of technical standard of third generation radio communication, the radio transmitting method of TD-SCDMA shows outstanding aspect transmission capacity.For the many antenna directivities technology that makes full use of the TD-SCDMA system further improves transmission capacity, utilize spatial character to distinguish the signal of different user, introduced SDMA (Space Division Multiple Access, space division multiple access inserts).
SDMA is a kind of form of spatial character as resource division, utilize the directivity of antenna to optimize the use of wireless frequency-domain and reduce system cost, make the user who is positioned at different directions or distinct coverage region use identical running time-frequency resource, expanded the resource pool of sub-district, thus the elevator system capacity.But SDMA only optimizes the part shared channel in physical layer, can't further optimize the advantage of dividing from system level with performance TD-SCDMA multi-antenna space, also there is certain influence while to the operate as normal of RRM (Radio Resource Management, RRM) algorithm.
In order to address the above problem the notion of having introduced cell portion Cell Portion, Cell Portion is actually and will classifies a traditional cellular cell branch as a plurality of subregion Portion, but they are from belonging to same sub-district in logic.The geographical coverage property of a sub-district may be different with the situation of this building, and a sub-district may have different geographical state or coverage condition on different points.Become a plurality of subregion Portion to a sub-district apportion, the thought of essence is to do the differentiation management according to the coverage property of geographic area.The application scenarios of Cell Portion comprises the indoor coverage mode of multichannel, as shown in Figure 1, a multichannel RRU (Radio Remote Unit, radio frequency far draws the unit) pull out antenna separately and cover, such as an antenna covers a floor or a plurality of floor, even can cover not chummery with different passages, form different Portion such as subregion 1, subregion 2, subregion 3.
Can use empty entire throughput of dividing the skill upgrading sub-district between the different Portion.Specifically on the basis of the indoor covering/SDMA of multichannel, increase reporting of measurement of correlation information, as because base station (NodeB) side can obtain RSCP (the Received SignalCode Power of UE up received signal of different Portion in the sub-district, received signal code power), therefore report the metrical information of the RSCP that comprises different Portion correspondences by the base station, after the metrical information that network side RNC reception Node B reports, determine the ownership Portion of UE according to the Portion of RSCP correspondence the strongest in the metrical information, determine that according to isolation parameter between pre-configured different Portion the ownership Portion with UE satisfies the Portion of isolation, can adopt the space division multiplexing mode to select to satisfy that UE and current UE carry out space division multiplexing among the Portion of isolation, therefore can more effectively give play to the advantage of TD-SCDMA.
Because the loss of indoor environment mainly comes from penetration loss, isolation between Cell Portion is comparatively fixing, belong to without the user between Portion, only otherwise moving of Portion occur striding, isolation big variation can not occur, and this point helps the auxiliary empty minute realization of Cell Portion.But after having introduced Cell Portion, terminal is between the Portion of same sub-district when mobile, original and terminal UE 1 is in another terminal UE 2 of empty branch state, because the change of UE1 position is moved between Cell Portion, the ownership Portion of the ownership Portion of UE1 and UE2 no longer satisfies the requirement of isolation after moving, if the continuation space division multiplexing will produce bigger interference to each other, traffic affecting normally carries out.Because CellPortion is transparent to terminal, promptly terminal itself does not know whether it moving between Portion taken place, so moving between Portion can not triggered any resource reprovision flow process.
Still there is not correlation technique strategy at present at this problem proposition.If only use original radio resource management method, after then terminal changes the Portion of its ownership, can not trigger any resource reprovision flow process, after can only expecting to disturb increase, network side just can trigger Radio Link detection algorithm RLS (Radio LinkSurveillance, Radio Link monitoring) and attempt the adjustment of resource.Adjustment needs certain time delay to resource owing to RNC, user experience this moment serious variation, and, may have the risk of call drop in the adjustment process because interference this moment is bigger.

Embodiment
Below in conjunction with drawings and Examples radio resource management method and the radio network controller that the present invention proposes illustrated in greater detail.
The present invention to use cell portion Cell Portion technology and is supporting in the environment of SDMA in order to solve, user terminal UE is between subregion Portion when mobile, may cause no longer satisfying and require and the formation strong jamming empty the branch, have a strong impact on the problem that the user uses, in embodiments of the invention one, a kind of radio resource management method is provided, divide multiplexing need state change situation in advance to judge and preliminary treatment user terminal at the by stages Mobile Space-time by this method, as shown in Figure 2, this method comprises:
Metrical information when step S201, network side obtain active user's terminal UE sky branch state, described metrical information comprises the special uplink channel received signal code power RSCP corresponding with different subregions;
As previously mentioned, the network side base station can obtain RSCP (the Received Signal Code Power of UE different subregion received signals in the sub-district, received signal code power), and can report and comprise with the metrical information of the RSCP of the corresponding special uplink channel of different Portion and give RNC, RSCP is corresponding with Portion, and representative is the RSCP from this Portion received signal.
Step S202, network side determine the difference of the strongest RSCP in the metrical information and time strong RSCP less than setting threshold Th, and this difference determines that the subregion of described strong RSCP correspondence is a target partition when surpassing scheduled duration less than duration of setting threshold;
Network side can obtain the strongest RSCP and the inferior difference of RSCP by force in the metrical information according to the metrical information that measures, the difference of the strongest RSCP and time strong RSCP is less than setting threshold Th, illustrate that UE the by stages may take place moves, in order to determine whether more accurately that further the by stages can take place moves, can increase by a timer in the present embodiment, timer picks up counting when determining difference less than setting threshold Th first, if when determining to surpass scheduled duration according to timer, difference in present embodiment determines then that always less than setting threshold Th the subregion of described strong RSCP correspondence is a target partition.Concrete grammar is not limited thereto, and can also adopt alternate manner.
Above-mentioned setting threshold Th specifically can determine according to the coverage condition of real network in the present embodiment, and when certain divided area edge, it advised general span 0dB-10dB in the upward signal received power difference of current subregion and adjacent sectors as test UE; The general scope of selecting of above-mentioned scheduled duration is also relevant with the coverage condition of real network, move to about 1/2 of two subregion intersections (the by stages difference power is 0) the used time according to distance between the adjacent sectors and user moving speed (it is generally acknowledged walking speed 3km/h) conversion user from a branch area edge (the by stages difference power reaches threshold value Th), advise general span 0ms-5000ms.
Step S203, network side obtain the ownership subregion with the UE of empty the branchs resource of current UE, and determine described ownership subregion whether and the isolation between described target partition satisfy the requirement of empty branch;
Because the isolation between cell portion is comparatively fixing, belongs to the user without the by stages, only otherwise occur striding moving of subregion, isolation big variation can not occur.The isolation that therefore can network side can obtain different by stages in advance according to geographical coverage property.The isolation that has only the by stages is during greater than certain threshold value, just thinks to satisfy and emptyly divides requirement promptly to satisfy empty spacer spare.Promptly be not that space division multiplexing can be adopted in all by stages in the sub-district; if moving to target partition, UE whether also satisfies the empty requirement that divides with its empty UE that divides by prejudging in the present embodiment with current; carry out the resource adjustment when requiring in advance in dissatisfied empty the branch; when specifically adjusting; can adopt existing resources to distribute; concrete adjustment mode is selected as required flexibly; move to the situation that target partition can cause interference so long as overcome UE; and guarantee that this resource adjustment can not produce the resource adjustment mode of new interference, all should fall within the present invention's scope required for protection.
The radio resource management method that proposes in the embodiment of the invention can be in the environment that utilizes Cell Portion technology, under changing, user terminal makes pre-judgments in advance and preliminary treatment before the Portion, avoid owing to no longer satisfying the empty strong jamming that divides the isolation condition to cause after moving, thereby guaranteed professional excellent perception of normally carrying out with the user.
Provide under the different situations network side among the step S203 below and adjust several preferred implementations of resource allocation, wherein a kind of situation is the current idling-resource that has, have under the situation of idling-resource, select in the present embodiment current UE and/or with the UE of empty the branchs resource of current UE in carry out the resource adjustment, wherein adjusting afterwards, the sky branch state of described current UE is disengaged.
Having under the situation of idling-resource, preferably use idling-resource, form new sky branch because use other resource to adjust the empty branch of other UE of participant, need also to guarantee can not cause new interference whether the requirement of satisfied empty branch waits judgement promptly to need to carry out isolation.And when using idling-resource, the used resource of current UE can be adjusted on the idling-resource, also can with the UE of empty the branchs resource of current UE in UE adjust on the idling-resource, also can both all adjust, as long as satisfy adjust after the sky branch state of current UE be disengaged.Like this,, can not cause interference, so and owing to be to use new resources rather than space division multiplexing resource can not cause new interference no matter whether UE takes place to move between Portion yet.
In the present embodiment, when the UE with the empty branch resource of current UE only had one, selection wherein any UE all could.Have when a plurality of at the UE with the empty branch resource of current UE, preferably that current UE is used resource is adjusted on the described idling-resource.Remove empty branch state and need adjust all and the current empty UE that divides because will guarantee current UE in this case, may make idling-resource cause resource anxiety etc. inadequately.
