Description
Technical field
The present invention relates to wireless domain, particularly a kind of wireless resource allocation methods, Apparatus and system.
Background technology
In more existing 3G, 4G networks, some system frequency ranges divide the concept adopting " multiband, same to community ", such as TD-SCDMA (TimeDivision-SynchronousCodeDivisionMultipleAccess, TD SDMA) system just introduces the concept of " multiband, same to community ", i.e. same community, have two different frequency ranges, but only use a dominant frequency.According to normalized definition in 5.2 of 3GPPTS25.105, following frequency range is allocated to TD-SCDMA technology standard: a) 1900-1920MHz, 2010-2025MHz; B) 1850-1910MHz, 1930-1990MHz; C) 1910-1930MHz; D) 2570-2620MHz; E) 2300-24000MHz; F) 1880-1920MHz.For the TD-SCDMA system of China Mobile, this TD-SCDMA system can use 2010-2025MHZ respectively, 1880-1920MHZ, 2300-2400MHZ, respectively referred to as a frequency range, f frequency range, e frequency range, for convenience follow-up, all represent with a frequency range, f frequency range, e frequency range.China Mobile, when 2007 start to dispose TD-SCDMA network, only uses 2010-2025MHZ, i.e. a frequency range.Therefore, all terminals are all support a frequency range.Along with the continuous expansion of TD-SCDMA network scale and the rising of capacity requirement, China Mobile introduced the deployment of 1880-1920MHZ frequency range and f frequency range in 2010, and therefore part new listing terminal also starts to support 1880-1920MHZ frequency range.This TD-SCDMA system is exactly the system of " multiband, same to community ".Certainly similar also have some other 3G, 4G network system, such as, WCDMA (WidebandCodeDivisionMultipleAccess in 3G, Wideband Code Division Multiple Access (WCDMA)) system or LTE (LongTermEvolution, Long Term Evolution) system etc.It should be noted that, the multiband of TD-SCDMA is disposed completely different from GSM: the 900MHZ frequency range of GSM and 1800MHZ frequency range use two different communities respectively, 1880-1920MHZ and the 2010-2025MHZ frequency range of TD-SCDMA then uses same community, and dominant frequency is generally among 2010-2025MHZ.
In TD-SCDMA system, terminal originating service first will carry out RRC (RadioResourceControl, radio resource control) connection establishment, in the foundation of RRC, UE (userequipment, user terminal) understand the ability telling RNC (RadioNetworkController, radio network controller) UE in RRCConnectionComplete (RRC connection establishment completes) this signaling.RRM (RadioResourceManagement, the RRM) algorithm of the ability that RNC can report according to UE and RNC is that UE distributes suitable Radio Resource (i.e. frequency, time slot, code channel).Such as, in certain RRC process of establishing, UE tells RNC in RRCConnectionComplete, and this UE supports a frequency range, i.e. 2010-2025MHZ.Meanwhile, be also support f frequency range, i.e. 1880-1920MHZ, after RNC have recorded the frequency range tenability of UE, according to the RRM algorithm of RNC setting, suitable frequency range can be distributed to UE in RB (RadioBearer, radio bearer) process of establishing.Because the resource utilization of f frequency range is far below a frequency range, for load sharing and the consideration reducing interference, in the RRM algorithm of RNC is arranged, as long as give tacit consent to UE in prior art to support a frequency range and f frequency range simultaneously, be just preferably UE and distribute f frequency range.But in actual applications, find that UE humorously cannot be transferred to f frequency range, cannot report RBSetupComplete (RB has set up) to RNC sometimes.RNC is after wait certain hour such as 5 second time-out, and report RABAssignmentResponse to CN, cause value is RNLCUeRabOperTimeOut, and namely RAB sets up time-out.

Embodiment
Below in conjunction with Figure of description, the preferred embodiment of the present invention is described, the embodiment of the present invention provides a kind of wireless resource allocation methods, Apparatus and system, to exist in the prior art that exists in prior art to solve, in the system of multiband with community, sometimes UE can because cannot the humorous RNC of being transferred to be the frequency range of its distribution, and the problem that cannot network.
Inventor finds when solving this technical problem, although as mentioned before, RNC can be support f frequency range and the RRM algorithm of self according to the frequency range tenability of terminal to report, UE can be preferably and distribute f frequency range, but this brings serious problems: once the frequency range tenability that UE reports does not conform to the frequency range tenability of self reality, then business can be caused to set up unsuccessfully simultaneously.Typical case is as follows, and it self is support f frequency range that certain model UE reports in RRCConnectionComplete, but in fact, by a large amount of signaling files and test analysis, finds that in fact the UE of this model does not support f frequency range.Which results in RAB sets up unsuccessfully, and business cannot normally be set up.RBSetup is based upon f frequency range by RNC.But UE does not support f frequency range due to actual frequency range ability, humorously cannot be transferred to f frequency range, and RBSetupComplete cannot be reported to RNC.RNC, after wait 5 time-out in second, reports RABAssignmentResponse to CN, and cause value is RNLCUeRabOperTimeOut, and namely RAB sets up time-out.
Based on the wireless resource allocation methods that this embodiment of the present invention provides, mainly based on following two real prerequisites: 1, all in existing network TD-SCDMA system terminals all support a frequency range (2010-2025MHz), but not necessarily all terminals (part terminal) all support f frequency (1880-1920MHz), that is support that the terminal of f frequency range must support a frequency range.2, to be set to f frequency range preferential for the RRM algorithm of RNC.This is because a frequency range is the frequency range that all terminals are all supported, assume responsibility for larger telephone traffic, therefore from the angle of load sharing, the default that f frequency range is preferentially existing network is set.
Embodiment of the present invention flow chart is illustrated in fig. 1 shown below, and comprises the steps:
Step 101, UE report to radio network controller (RNC) in radio resource control RRC connection establishment process, represent that UE supports the information of f frequency range.
Step 102, RNC for for UE priority allocation f frequency range, are UE distribution a frequency range in the frequency allocation rule preset.
Step 103, UE report radio bearer to set up message to RNC.
After the radio bearer that step 104, RNC reception UE reports has set up message, issue the message of reprovision to f frequency range to UE.
Owing to first distributing a frequency range that whole UE all supports in UE access procedure, then reprovision is to f frequency range, thus to avoid because reporting the UE that causes by mistake cannot the humorous RNC of being transferred to be the frequency range that it distributes, and cannot network.
Below in conjunction with Fig. 2, the embodiment of the present invention is described in detail.
Step 201, UE, in RRC process of establishing, report and self support f frequency range in RRCConnectionSetupComplete.
If support the terminal of f frequency range, also necessarily support a frequency range simultaneously, on the contrary quite different.RRCConnectionComplete in this step.
Step 202, judge, in the RRM algorithm of RNC, whether to be set to priority allocation f frequency range, to be, enter step 204; Otherwise enter step 203.
The frequency allocation preset rule in the present embodiment is by the RRM algorithm realization of RNC.
Step 203, RNC just distribute a frequency range for UE, enter step 210.
Step 204, RNC are first the core frequency band a frequency range of UE distribution T D-SCDMA.
In this step, unpromising UE distributes f frequency range (should the frequency range of priority allocation according to RRM algorithm), but distributes a frequency range, can guarantee that UE first can successful access network like this.
Step 205, RNC receive the RBSetupComplete message that UE reports, and trigger RNC and issue RBReconfiguration or PhysicalChannelReconfiguration to UE, by UE reprovision to f frequency range.
RBSetupComplete message flag RB and has been set up.RBSetupComplete message can trigger RNC and issue RBReconfiguration (radio bearer reconfigures message) or PhysicalChannelReconfiguration (physical channel reconfigures message) to UE, by UE reprovision to f frequency range.
Step 206, UE judge whether to support f frequency range, if in fact UE does not support f frequency range, then enter step 208; If in fact UE supports f frequency range, then enter step 207.
In fact may not support f frequency range by the known UE of this step, but it reports self support f frequency range by mistake in RRC process of establishing.
Step 207, reprovision, to f frequency range, enter step 210.
Step 208, UE reply RNC with RBReconfigurationFailure or PhysicalChannelReconfigurationFailure.
The failure cause carried is: InvalidConfiguration/ConfigurationUnsupported (error configurations/configuration is not supported).Owing to there being the rollback mechanism of handoff failure, the failure of RBReconfigurationFailure reprovision or PhysicalChannelReconfigurationFailure physical channel reprovision unsuccessfully can't affect the business that UE carries out.After reprovision failure, UE can continue in the enterprising industry business of a frequency range.RB reprovision failed message or physical channel reprovision failed message are all reprovision failed messages, represent that UE reality does not support f frequency range.
Step 209, RNC record the actual frequency range tenability of this UE, as the foundation of Resourse Distribute when switching in RNC.
If across RNC switch, then by former RNC in RelocationRequired signaling notification target RNC about the ability of this terminal.
Step 210, enter business processing flow.
When this step is specifically implemented, can be carry out follow-up normal call flow.
