Embodiment
The present invention provides carrier frequency method of adjustment, system, base station and the device in a kind of frequency division systems; Basic thought is; When idle local carrier frequency or free local carrier frequency are arranged in the base station, the radio-resource-configuration of recovered failure carrier frequency on the local carrier frequency of free time or free local carrier frequency; When not having idle local carrier frequency or free local carrier frequency in the base station; Select a normal carrier frequency as being seized carrier frequency; And seized carrier frequency fault through resource status Indication message notice radio network controller; To be seized the Radio Link of carrier frequency and adjust to other carrier frequency, radio network controller and base station are deleted respectively and are seized the resource distribution of other except that Radio Link on the carrier frequency, are being seized the radio-resource-configuration of recovered failure carrier frequency on the corresponding local carrier frequency of carrier frequency.
In order to make those skilled in the art person understand the present invention program better, the present invention is done further detailed description below in conjunction with accompanying drawing and execution mode.
NodeB is the entity in the wireless network, comprises one or more sub-districts.In NodeB, home cell is the general name of a cover software and hardware resources, and is corresponding one by one with the sub-district.The sign of home cell (Local Cell Id) is given RNC and Node B by administrator configurations; The corresponding relation of home cell and sub-district is given RNC by administrator configurations.For a sub-district that N carrier frequency arranged, comprise N part resource in its corresponding home cell and can carry N carrier frequency respectively, we claim that a resource wherein is a local carrier frequency.Sometimes; The software and hardware resources that has some not included in home cell among the NodeB, purpose are as redundancy backup, when they are activated; Can be brought into by NodeB becomes local carrier frequency in certain home cell, we claim that the resource of these redundancy backups is free local carrier frequency.Sometimes; Local carrier frequency number is greater than the number of corresponding district carrier frequency in the home cell of administrator configurations; After the sub-district is set up, have in the home cell on the local carrier frequency of part and do not carry corresponding carrier frequency, we are referred to as idle local carrier frequency this part local carrier frequency; According to the concrete difference that realizes of NodeB, these idle local carrier frequency of back are set up in the sub-district possibly also can be marked as free local carrier frequency.
Below introduce method of the present invention.When certain carrier frequency among the NodeB breaks down, comprising:
When idle local carrier frequency or free local carrier frequency are arranged in the NodeB, the radio-resource-configuration of recovered failure carrier frequency on an idle local carrier frequency or free local carrier frequency.
The radio-resource-configuration of said recovered failure carrier frequency comprises that broadcasting, pilot tone, common signal channel, the high speed downlink packet on the recovered failure carrier frequency inserts (High Speed Downlink PacketAccess, HSDPA) shared channel, public-measurement, Radio Link and special measurement.
The radio-resource-configuration of recovered failure carrier frequency on an idle local carrier frequency or free local carrier frequency can keep user on the fault carrier frequency to recover and being connected of base station, thereby continue to converse or carry out data service.
When not having idle local carrier frequency or free local carrier frequency in the NodeB, Fig. 3 shows the flow chart of the inventive method embodiment under this situation, and is as shown in the figure, comprising:
Step 301: select a normal carrier frequency to be seized carrier frequency, and seized carrier frequency fault through resource status Indication message notice RNC as quilt.
Can be seized carrier frequency according to the selective sequential from low to high of carrier frequency priority.For example, normally, the priority of carrier frequency is according to arranging as follows from high to low:
1, main carrier frequency;
2, the many carrier frequency of HSDPA carrier frequency and number of users;
3, the few carrier frequency of HSDPA carrier frequency and number of users;
4, do not dispose the many carrier frequency of HSDPA and number of users;
5, do not dispose the few carrier frequency of HSDPA and number of users.
Seized in the carrier frequency process selecting, can be according to priority from low to high order carry out, promptly undertaken by 5 to 1 order, can make the possibility of the influence that the high user of the grade of service receives minimum like this, also can reduce affected number of users simultaneously as far as possible.
The said carrier frequency of being seized can be selected in the NodeB scope at current fault carrier frequency place, and is not limited only to the sub-district at current fault carrier frequency place.
Seized carrier frequency fault through resource status Indication message notice RNC, further, seized carrier frequency place cell status and change into and degrading.Said degrade to refer to have the part carrier frequency unavailable in the multi-carrier frequency cell.
Step 302:RNC will be seized the Radio Link of carrier frequency and adjusted to other carrier frequency, and RNC and NodeB delete respectively and seized the resource distribution of other except that Radio Link on the carrier frequency.
Preservation is seized the Radio Link on the carrier frequency and it is adjusted to other carrier frequency, can the user that this quilt is seized on the carrier frequency be adjusted to other carrier frequency further, thereby keep these users' connection.
RNC and NodeB preserve the resource distribution of being seized carrier frequency separately, and therefore, RNC and NodeB delete the quilt of preserving separately respectively and seize the resource distribution of other except that Radio Link on the carrier frequency.
Can also delete presumable common signal channel and corresponding transport network layer resource, HSDPA shared channel, public-measurement and special measurement.Above-mentioned these configurations are all relevant with carrier frequency.After carrier frequency was seized, this carrier frequency no longer was present in this sub-district, and the configuration to carrier frequency has not just needed yet so, therefore, deletes these resources here.
If being seized has the user on the carrier frequency; This step is deleted respectively at RNC and NodeB and is seized on the carrier frequency before the resource distribution of other except that Radio Link; NodeB also must back up these user's radio resource configuration informations; And RNC utilizes the radio-resource-configuration of NodeB backup, and (Dynamic Channel Allocation, the user who DCA) this quilt is seized on the carrier frequency adjusts on the normal carrier frequency through dynamic channel allocation.One skilled in the art will appreciate that be this area conventional techniques means through the corresponding user of DCA adjustment radio-resource-configuration to other carrier frequency.
Step 303: seized the radio-resource-configuration of recovered failure carrier frequency on the corresponding local carrier frequency of carrier frequency.
Comprise one or more combination in broadcasting, pilot tone, common signal channel, HSDPA shared channel, public-measurement, Radio Link and the special measurement on the recovered failure carrier frequency.Can be one or several combination in the content of above-mentioned recovery, reason be and need recovers according to the original configuration of fault carrier frequency.For example, do not have Radio Link on the fault carrier frequency originally,, just need not reply Radio Link here.Again for example, common signal channel only can if fault is assistant carrier frequency, just need not recover common signal channel when recovering so on main carrier frequency.
Because the radio-resource-configuration of fault carrier frequency is recovered rapidly, user's connection can not broken off on the fault carrier frequency.In other words, can keep the user on the fault carrier frequency to recover and being connected of base station being seized on the carrier frequency, thereby continue to converse or carry out data service.
Further, can also may further comprise the steps:
Step 304: after fault carrier frequency corresponding software and hardware resource is recovered from fault; The base station detects idle local carrier frequency; On the local carrier frequency of free time, recover to be seized the radio-resource-configuration of carrier frequency; Seized carrier frequency through resource status Indication message notice RNC and recover, it is normal that cell status recovers.
The sub-district use that degrades is mentioned in the front, in this step, and the cell recovery normal condition; If do not carry out recovering step after the carrier frequency in the sub-district breaks down, the carrier frequency number can reduce.
Below introduce a full implementation example of the inventive method.
Fig. 4 shows the flow process of this full implementation example.
Step 401: whether inspection has idle local carrier frequency or free local carrier frequency in the NodeB, if execution in step 402 then, if otherwise execution in step 403.
Step 402: the local carrier frequency that will select is included the corresponding home cell of fault carrier frequency in; And on this this locality carrier frequency the radio-resource-configuration of recovered failure carrier frequency; Comprise broadcasting, pilot tone, common signal channel, HSDPA shared channel, public-measurement, Radio Link and special measurement on the recovered failure carrier frequency, change step 408 over to.
Step 403: select a normal carrier frequency as being seized carrier frequency, RNC is seized carrier frequency fault through resource status Indication message notice, is seized carrier frequency place cell status and changes into and degrading.
The carrier frequency step is seized in said selection, normally, can select according to carrier frequency priority order from low to high, and the priority of carrier frequency is according to arranging as follows from high to low:
1, main carrier frequency;
2, HSDPA carrier frequency, the carrier frequency that number of users is many;
3, HSDPA carrier frequency, the carrier frequency that number of users is few;
4, do not dispose the many carrier frequency of HSDPA and number of users;
5, do not dispose the few carrier frequency of HSDPA and number of users.
Saidly selecting according to carrier frequency priority order from low to high, promptly is that from 5 to 1 order is selected.
Step 404: judge to be seized whether the user is arranged on the carrier frequency, if, execution in step 405; If not, execution in step 406.
Step 405:NodeB backup user's radio resource configuration information, and RNC utilizes the radio-resource-configuration of NodeB backup, and the user who this quilt is seized on the carrier frequency through DCA adjusts on the normal carrier frequency.
Step 406:RNC will be seized the Radio Link of carrier frequency and adjusted to other carrier frequency; RNC and NodeB delete respectively and are seized the resource distribution of other except that Radio Link on the carrier frequency, comprise presumable common signal channel and corresponding transport network layer resource, HSDPA shared channel, public-measurement, special measurement.
Step 407:, comprise one or more combination in broadcasting, pilot tone, common signal channel, HSDPA shared channel, public-measurement, Radio Link and the special measurement on the recovered failure carrier frequency being seized the radio-resource-configuration of recovered failure carrier frequency on the corresponding local carrier frequency of carrier frequency.
Because the radio-resource-configuration of fault carrier frequency is recovered rapidly, the user's connection on the fault carrier frequency can not broken off.
Step 408: after fault carrier frequency corresponding software and hardware resource is recovered from fault; The base station detects idle local frequency; On the local frequency of free time, recover to be seized the radio-resource-configuration of carrier frequency, seized carrier frequency recovery, cell status recovery normally through resource status Indication message notice RNC.
Through above-mentioned steps, can keep the user on the fault carrier frequency to recover and being connected of base station being seized on the carrier frequency, thereby continue to converse or carry out data service.
