Description
Technical field
The present invention relates to mobile communication technology field, particularly relate to a kind of wireless resource allocation methods and system.
Background technology
At present, the third generation (The Third Generation, being called for short 3G) mobile communication technology is in global extensive use, along with the development of wireless technology and the continuous proposition of user's request, communication system and user terminal (User Equipment, be called for short UE) all constantly realizing New function, improve old function.Thus the function of communication system and user terminal gets more and more, and wireless capability is also more and more stronger.
In the evolution of 3G mobile communication technology, the compatibility issue of network to terminal capability will be caused.Because network side cannot know the wireless capability that whole reality of terminal are supported, then can accurately be not its distributing radio resource according to the practical capacity of terminal, thus cause quality of service deterioration or business to be set up unsuccessfully.Therefore accurately according to terminal practical capacity distributing radio resource, improve the ability of system compatible terminal, just become the important topic improving network service quality and user's susceptibility.
At 3GPP(The Third Generation Partnership Project, third generation partner program) TS25.331 agreement in define the signaling of two its wireless access capabilities of terminal to report, RRC(Radio Resource Control respectively, radio resource control) connection establishment completes (RRC Connection Setup Complete) and UE ability information (UE Capability Information), and these two signalings are all that terminal offers network side.When terminal originating service, wireless resource control connection request (RRC Connection Request) message can be sent out to network, network issues wireless heterogeneous networks connection establishment (RRC Connection Setup) to UE, then UE returns network side radio resources control connection establishment and completes (RRC Connection Setup Complete) message, its ability of active reporting.Or, network side also can initiatively to UE query capability, network issues UE capability query (UE Capability Enquiry) message to UE, UE reports UE ability information (UE Capability Information) message, and network issues UE ability information to UE again and confirms (UE Capability Information Confirm) message.
After radio network controller (Radio Network Controller is called for short RNC) gets UE ability, first carry out this locality and preserve.RNC receives core net (Core Network, be called for short CN) RAB assignment request (the Radio Access Bearer Assignment Request that sends, be called for short RAB assignment request) message, RNC resolves the information such as type of service, speed that RAB assignment request band gets off.RRM (the Radio Resource Management of RNC, being called for short RRM) algorithm is according to the UE wireless access capability of local preservation before, such as uplink physical channel ability (uplinkPhysChCapability), down physical channel ability (downlinkPhysChCapability) etc., distribute the business that the Radio Resources such as frequency, time slot, code channel carry RAB assignment request for UE.Then, the Radio Resource distributed is issued base station by wireless link reconfigured preparation (Radio Link Reconfiguration Prepare) or wireless link request (Radio Link Setup Request) message, sets up (Radio Bearer Setup) message by radio bearer and issue UE.Last base station and UE work on the Radio Resource of correspondence, and business is set up.
But mainly there is following deficiency in existing said method:
1, when RNC is to UE distributing radio resource, the ability of failing outside the UE wireless capability considering to carry in RRC connection setup complete message and UE capability information message.Said method is only according to the capability distribution Radio Resource that UE reports in RRC connection setup complete message or UE capability information message, and the ability outside the ability of failing to consider that these two message are carried.Such as HSPA(high-speed packet access) the adjoint DPCH(DPCH of business) multiplexing capacity.If network side is supported multiplexing, UE does not support, and network side cannot know whether UE supports, then RNC gives tacit consent to the support of UE ability, is assigned with multiplexing resource to UE, beyond UE ability, then quality of service deterioration or business will be caused to set up unsuccessfully;
2, when RNC is to UE distributing radio resource, the ability of failing to consider that part model UE reports and the inconsistent situation of its practical capacity.Existing network is by terminal, some is early production, and software or hardware existing defects, the actual wireless capability supported may not conform to the wireless capability reported (as descending every time slot greatest physical number of channel of the support reported be greater than actual support).Because RNC cannot know the practical capacity of UE, conventionally, the capability distribution Radio Resource that RNC reports in RRC connection setup complete message or UE capability information message according to UE, the Radio Resource of distribution can exceed UE practical capacity, then quality of service deterioration or business will be caused to set up unsuccessfully.

For the ease of setting forth the present invention, be described in further detail below with reference to the enforcement of drawings and the specific embodiments to technical solution of the present invention.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.
Provide a kind of system in the embodiment of the present invention to the distribution method of terminal distribution Radio Resource, realize in network element device RNC.As shown in Figure 1, the wireless resource allocation methods based on IMEI of the present embodiment, mainly comprises the steps:
Step 1, set up the actual tenability case library of UE;
In the database of RNC, set up the case library of the UE actual support wireless capability based on IMEI, the UE ability in case library has following features: do not report in RRC connection setup complete message and UE capability information message, part terminal is not supported, the RRM algorithm of RNC supports to giving tacit consent to UE during UE distributing radio resource; Or, report in RRC connection setup complete message or UE capability information message, the actual tenability of part terminal be less than its ability reported, the RRM algorithm of RNC according to the ability reported to UE distributing radio resource.
The IMEI of step 2, acquisition UE;
In the present embodiment, concrete acquisition process is as follows: RNC receives the Initial Direct Transfer(initial direct-sending that UE reports) after message, DownlinkDirectTransfer(is descending direct transfers for structure) message is handed down to UE, requires that UE reporting terminal identifies IMEI(International Mobile Equipment Identity International Mobile Station Equipment Identification); RNC monitors that the UplinkDirectTransfer(that reports of UE is up to direct transfer) message, extract UE identification response UplinkDirectTransfer(Identity Response) (Identity response) message first eight bits of IMEI of carrying preserving.
In said process, RNC is by structure DownlinkDirectTransfer(Identity Request) message is handed down to UE, indicates inquiry IMEI; And by monitoring UplinkDirectTransfer(Identity Response) message, extract and preserve first 8 of its IMEI carried.
When step 3, RRM algorithm are to UE distributing radio resource, call each subalgorithm;
RRM allocation of radio resources algorithm can arrange corresponding subalgorithm for often kind of capability class, and each subalgorithm inquires about the UE ability needed for oneself respectively.
In the present embodiment, when in business process of establishing, RNC is to UE distributing radio resource, according to front 8 capability for registration of inquiring about this model terminal in terminal capability case library of IMEI.
Concrete, when RNC is traffic assignments Radio Resource after receiving RAB assignment request message, RRM subalgorithm inquires about the ability that oneself needs in case library.
Composition graphs 1, subalgorithm 1 is the ability outside specifying for agreement, as the ability outside the UE wireless capability that carries in RRC connection setup complete message and UE capability information message, then subalgorithm 1 according to the IMEI of UE front 8 from DBS(Data Base System, Database Systems) whether be whether 1(namely support) if inquiring about this UE capable field value, if Query Result is for supporting, then subalgorithm is according to existing algorithm assigns Radio Resource, if Query Result is not supported, then subalgorithm does not distribute this ability corresponding Radio Resource, therefore the operation result of subalgorithm can not exceed corresponding ability, the Radio Resource finally distributed to UE also can not exceed UE ability.
Subalgorithm 2 be for UE actual support be less than its ability reported, then subalgorithm 2 whether according to first 8 of IMEI, to inquire about this UE capable field value from DBS be that namely whether 1(be less than), if Query Result is for being not less than, then subalgorithm is according to existing algorithm assigns Radio Resource, if Query Result is for being less than, then subalgorithm is UE distributing radio resource by system specific capability, and system specific capability is the most conservative value of this ability that each model terminal has been supported.According to the operation result of each subalgorithm, RRM draws finally to the Radio Resource that UE distributes.
Be be UE distributing radio resource according to the actual tenability of UE or system specific capability due to each subalgorithm, therefore the operation result of subalgorithm can not exceed UE practical capacity, and the Radio Resource finally distributed to UE also can not exceed UE practical capacity.
Fig. 2 is the explanation of field of the case library table of the embodiment of the present invention, and the data type providing field supplies to implement reference.The present embodiment specifically describes as follows:
One, first in the Operation and Maintenance webmaster of RNC, terminal capability case library is set up, case library and database.Field IMEINO is major key field, and value is 8 integers, and default value is 00000000, is defined as numeric type (number) in network management data storehouse.
In order to reduce the data maintenance amount of case library, field IMEINO fills out the first eight bits of IMEI, and the first eight bits of IMEI can represent a kind of terminal of model.Except IMEINO field, also comprise UE capable field, be specially capability class (Type) field, the value of capability class field can only be 0 or 1, is defaulted as 1, is defined as numeric type (number) in network management data storehouse.
In the present embodiment, the implication of UE capable field has two kinds:
(1) whether a kind of expression terminal supports this ability (the field DpchInd in the present embodiment represents whether terminal supports DPCH multiplexing capacity), value 0 represents not to be supported, value 1 expresses support for, and this ability cannot report in RRC connection setup complete message and UE capability information message;
(2) whether the another kind of ability representing that reality is supported is less than the ability reported, and value 0 represents and is less than, and value 1 represents and is not less than, and this ability can report in RRC connection setup complete message and UE capability information message.The field of two kinds of implications can have multiple respectively, is defined as required by RNC manufacturer.
As shown in Figure 3, field DLMaxPhyChPerTsInd wherein represents whether descending every time slot greatest physical number of channel of the actual support of terminal is less than its descending every time slot greatest physical number of channel reported.
Must comprise a default record in case table, the UE ability of register system acquiescence, the IMEINO of default record is 00000000, and other field value is 1, and default record can not be revised.The modes such as manufacturer can be tested by IOT, Pilot office test, the test of commercial net collect the information of the UE not meeting default capabilities, will insert in table for information about, as dispatching from the factory initial configuration together with default record.User can delete non-default record, retouching operation, and user also can collect the information of the UE not meeting default capabilities voluntarily simultaneously, will configure into case library for information about.Case library is synchronized to RNC Foreground Data storehouse from webmaster.
Two, the IMEI number of UE is obtained
Refer to Fig. 4, concrete obtaining step is as follows:
1) in business initiation process, RNC receives initial direct-sending (the Initial Direct Transfer) message that UE reports, and judges it is CS territory or PS territory according to the domain identifier carried in initial direct-sending.If CS territory, construct descending direct-sending message DownlinkDirectTransfer(MM:Identity Request) be handed down to UE, the domain identifier wherein carried is filled out as CS, NasMessage is totally 3 bytes, and first byte of NasMessage, the second byte, the 3rd byte are filled out respectively as 0x05,0x18,0x02.If PS territory, construct descending direct-sending message DownlinkDirectTransfer(GMM:Identity Request) be handed down to UE, the domain identifier wherein carried is filled out as PS, NasMessage is totally 3 bytes, and the first byte, the second byte, the 3rd byte are filled out respectively as 0x08,0x15,0x02.Start timer T and wait for that UE reports IMEI.
2) during timer T, RNC monitors the UplinkDirectTransfer message that UE reports, and resolves the NasMessage wherein carried.Calculate NasMessage.data [0] & 0x0F result and equal 0x05, be expressed as MM(mobility management messages, mobile management message) message, result of calculation equals 0x08, be expressed as GMM(GPRS mobility management messages, GPRS mobile management message) message.Calculate NasMessage.data [1] & 0x3F result and equal 19, be then the Identity Response of MM process, result of calculation equals 16, be then the Identity Response of GMM process.Calculate NasMessage.data [3] & 0x07 result and equal 0x02, then the UE carried is designated IMEI.
RNC carries out analysis judgment after receiving up direct-sending message, if meet 3 conditions: domain identifier is CS territory, is MM message, is the Identity Response of MM process simultaneously, or meet 3 conditions: domain identifier is PS territory, is GMM message, is the Identity Response of GMM process simultaneously, judge that the UE carried is designated IMEI again, then kill timer T, extract the first eight bits of the IMEI in NasMessage and preserve, flow process terminates.Otherwise exit judgement, continue to monitor next up direct-sending message, until timer T is overtime.
From the low 4bit of NasMessage the 4th byte, represent an IMEI to the low 4bit of the 8th byte, every 4bit, totally 8, the corresponding relation of bit and the IMEI of each byte refers to Fig. 5.
Three, in the RRM allocation of radio resources algorithm of RNC, several subalgorithms are increased, a kind of UE ability in the corresponding case library of each subalgorithm.After receiving RAB assignment request message, when the allocation of radio resources algorithm of RRM is traffic assignments Radio Resource, call RRM subalgorithm one by one.
The first eight bits of this user IMEI of subalgorithm reading and saving, is assigned to DBS by the UE capable field name of front 8 and the required inquiry of IMEI and searches, and after DBS finds the value of this corresponding UE capable field according to 8 IMEI, return value is to subalgorithm.If without the record of this IMEI in UE ability case library, DBS searches unsuccessfully, then return the value (namely field IMEINO value is the value of this UE capable field of the record correspondence of 00000000) of default record to subalgorithm.
If subalgorithm inquiry is ability outside the UE wireless capability that carries in RRC connection setup complete message and UE capability information message.When DBS return value is 1, subalgorithm is according to existing algorithm assigns resource, and when DBS return value is 0, subalgorithm does not distribute this ability corresponding Radio Resource, and the resource of distribution is supported without the need to this ability.
If whether the ability that the capable field implication of subalgorithm inquiry is actual support is less than the ability reported.When DBS return value is 1, subalgorithm is according to existing algorithm assigns resource, and when DBS return value is 0, subalgorithm is that UE distributes respective wireless resource according to the system specific capability of this ability.System specific capability is the most conservative value of this ability that each model business terminal has been supported, and specific capability value is defined (the system specific capability value that the present embodiment defines descending every time slot greatest physical number of channel is 12) in a program by subalgorithm.
Such as IMEI first eight bits is the terminal initiation packet territory background business of 86021900, and after receiving RAB assignment request, RRM allocation of radio resources algorithm assigns Radio Resource carries this business.Call subalgorithm 1, the value getting this model terminal corresponding field DpchInd from DBS is 1, then according to former algorithm, acquiescence UE supports that DPCH is multiplexing, is UE distributing radio resource.Call subalgorithm 2, the value getting field DLMaxPhyChPerTsInd is 0, then by system specific capability Resources allocation, namely think that descending every time slot greatest physical number of channel that this UE supports is 12, the resource that subalgorithm 2 ensures UE to distribute meets descending every time slot greatest physical number of channel and is not more than 12.
Such as IMEI first eight bits is the terminal initiation packet territory background business of 86021901, and after receiving RAB assignment request, RRM allocation of radio resources algorithm assigns Radio Resource carries this business.Call subalgorithm 1, the value getting this model terminal corresponding field DpchInd from DBS is 0, then subalgorithm 1 filters out multiplexed resource, and what ensure UE to distribute is non-multiplexed resource.Call subalgorithm 2, the value getting field DLMaxPhyChPerTsInd is 1, then according to existing algorithm assigns resource, the resource of distributing for UE meets descending every time slot greatest physical number of channel and is not more than descending every time slot greatest physical number of channel that UE reports.
After the computing of RRM allocation of radio resources algorithm is complete, by the details of the Radio Resource such as frequency, time slot, code channel distributed, issue base station by wireless link reconfigured preparation (Radio Link Reconfiguration Prepare) or wireless link request (Radio Link Setup Request) message, set up (Radio Bearer Setup) message by radio bearer and issue UE.Subsequent base stations and RNC by wireless link reconfigured response (Radio Link Reconfiguration Response), (after the messaging negotiates such as Radio Link Setup Response, wireless link reconfigured confirmation (Radio Link Reconfiguration Commit), base station switches on new Radio Resource and works in wireless link response.UE also switches to after receiving message on new Radio Resource and works, and returns radio bearer set up (Radio Bearer Setup Complete) message to RNC.Successfully set up to this business.
After business is set up, other scene is also had to need for user redistributes Radio Resource, such as: minizone cell update in handover between cells, RNC, intra-cell resource adjustment, another business concurrent etc. in RNC.The present invention program is adopted to be UE distributing radio resource in these scenes, minizone cell update success rate, intra-cell resource in handover between cells success rate, RNC can be improved in RNC and is adjusted to power, service concurrence success rate, avoid RNC to exceed UE ability to the Radio Resource that UE distributes and the quality of service that causes worsens or call drop, contribute to the UE of the different ability of Web-compatible.
