Description
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.In order to make full use of many antenna directivities technology of TD-SCDMA system, further improve transmission capacity, utilize spatial character to distinguish the signal of different user, introduced SDMA (Space Division Multiple Access, space division multiple access access).
A kind of form of SDMA using spatial character as resource division, utilize the directivity of antenna 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 community, thus capacity.But SDMA is only optimized partial sharing channel in physical layer, cannot carry out further optimizing the advantage with performance TD-SCDMA Using Multi-Antennas of Difference from system level, also the normal operation of RRM (Radio Resource Management, RRM) algorithm is had to certain influence simultaneously.
In order to address the above problem the concept of having introduced cell portion Cell Portion, Cell Portion is actually and a traditional cellular cell will be divided and classified a plurality of subregion Portion as, but they are from belonging in logic same community.The geographical coverage property of Yi Ge community may may have different geographical state or coverage condition in different ，Yi Ge community with the situation of this building on different points.Yao Bayige community apportion becomes a plurality of subregion Portion, and the thought of essence is to do 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 Yuan La unit) pull out separately antenna cover, such as floor of an antenna cover or a plurality of floor, even can cover with different passages not chummery, form different Portion as subregion 1, subregion 2, subregion 3.
Between different Portion, can apply the entire throughput of empty minute skill upgrading community.Specifically on the basis of the indoor covering/SDMA of multichannel, increase reporting of correlation measurement information, as obtained RSCP (the Received SignalCode Power of different Portion uplink receiving signals in UECong community due to base station (NodeB) side, received signal code power), therefore by base station, report the metrical information of the RSCP that comprises that different Portion are corresponding, after the metrical information that network side RNC reception Node B reports, according to Portion corresponding to RSCP the strongest in metrical information, determine the ownership Portion of UE, according to isolation parameter between pre-configured different Portion, determine that the ownership Portion with UE meets the Portion of isolation, can adopt space division multiplexing mode to select to meet UE and current UE in the Portion of isolation and carry out space division multiplexing, 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 occur the movement across Portion, isolation there will not be large variation, and this point is conducive to the Cell Portion realization of auxiliary empty minute.But after having introduced Cell Portion, when terminal moves between the Portion of same community, original and terminal UE 1 is divided another terminal UE 2 of state in sky, because the change of UE1 position is moved between Cell Portion, after mobile, the ownership Portion of UE1 and the ownership Portion of UE2 no longer meet the requirement of isolation, if continuation space division multiplexing, will produce larger interference to each other, traffic affecting normally carries out.Because CellPortion is transparent to terminal, terminal itself does not know whether it movement between Portion has occurred, so the movement between Portion can not trigger any resource reprovision flow process.
Still the correlation technique strategy not proposing for this problem at present.If only use original radio resource management method, terminal changes after the Portion of its ownership, can not trigger any resource reprovision flow process, can only expect to disturb after increase, network side just can trigger Radio Link Detection algorithm RLS (Radio LinkSurveillance, wireless link monitoring) and attempt the adjustment of resource.Because RNC need to have certain time delay to resource adjustment, now user has experienced seriously variation, and larger owing to now disturbing, and may have the risk of call drop in adjustment process.

Embodiment
The radio resource management method and the radio network controller that the present invention are proposed below in conjunction with drawings and Examples illustrate 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, when user terminal UE moves between subregion Portion, may cause no longer meeting empty minute requires and formation strong jamming, have a strong impact on the problem that user uses, in embodiments of the invention one, a kind of radio resource management method is provided, by the method, to user terminal, at by stages Mobile Space-time, divide the multiplexing state change situation that needs to judge in advance and preliminary treatment, as shown in Figure 2, the method comprises:
Step S201, metrical information when network side obtains empty minute state of active user's terminal UE, described metrical information comprises the special uplink channel received signal code power RSCP corresponding from different subregions;
As previously mentioned, network side base station can obtain RSCP (the Received Signal Code Power of different subregions reception signals in UECong community, received signal code power), and can report the metrical information of the RSCP that comprises the special uplink channel corresponding from different Portion to RNC, RSCP is corresponding with Portion, and representative is from this Portion, to receive the RSCP of signal.
Step S202, network side determines that in metrical information, the difference of the strongest RSCP and inferior strong RSCP is less than setting threshold Th, and this difference duration of being less than setting threshold while surpassing scheduled duration, determines that described strong subregion corresponding to RSCP is target partition;
Network side can obtain the difference of the strongest RSCP and inferior strong RSCP in metrical information according to the metrical information that measures, the difference of the strongest RSCP and inferior strong RSCP is less than setting threshold Th, illustrate that UE by stages may occur and moves, in order further to determine whether more accurately that by stages can occur moves, in the present embodiment, can increase by a timer, when determining that difference is less than setting threshold Th first, timer starts timing, if while determining over scheduled duration according to timer, difference is less than setting threshold Th always, in the present embodiment, determine that described strong subregion corresponding to RSCP is target partition.Concrete grammar is not limited to this, can also adopt alternate manner.
In the present embodiment, above-mentioned setting threshold Th specifically can determine according to the coverage condition of real network, and if test UE is when certain minute area edge, it,, in the upward signal received power difference of current subregion and adjacent sectors, advises general span 0dB-10dB; The general scope of selecting of above-mentioned scheduled duration is also relevant with the coverage condition of real network, according to the distance between adjacent sectors and user moving speed (it is generally acknowledged walking speed 3km/h) conversion user from one minute area edge (by stages difference power reaches threshold value Th) move to two subregion intersections 1/2 left and right of (by stages difference power is 0) time used, advise general span 0ms-5000ms.
Step S203, network side obtains the ownership subregion of the UE of the empty minute resource of same current UE, and the isolation of determining described ownership subregion whether and between described target partition meets the empty requirement that divides;
Because the isolation between cell portion is comparatively fixing, belong to the user without by stages, only otherwise occur the movement across subregion, isolation there will not be large variation.Therefore can obtain in advance according to geographical coverage property the isolation of different by stages by network side.While only having the isolation of by stages to be greater than certain threshold value, just think that meeting empty minute requires to meet empty spacer part.Be not that in community, all by stages can adopt space division multiplexing, if move to target partition and whether also meet empty minute requirement with current with its UE of empty minute by prejudging UE in the present embodiment, when within dissatisfied empty minute, requiring, carry out in advance resource adjustment, while specifically adjusting, can adopt existing resource to distribute, concrete adjustment mode is selected as required flexibly, so long as overcome UE, move to the situation that target partition can cause interference, and guarantee that this resource adjustment can not produce the resource adjustment mode of new interference, within all should falling into the present invention's scope required for protection.
