2) in the radio network controller side:
Require inaccessible main carrier frequency in the inaccessible request message of receiving, according to inaccessible priority, radio network controller is removed all business of main carrier frequency on the sub-district;
Inaccessible when being assistant carrier frequency when requiring in the inaccessible request message of receiving, radio network controller only remove on the assistant carrier frequency business;
Similar, when receive the base station separate block message the time, be main carrier frequency if separate inaccessible, so only allow to call out with the logical resource on the main carrier frequency, be that assistant carrier frequency so only allows calling with the logical resource on the assistant carrier frequency if separate inaccessible.
3) in base station side:
Because in multi-carrier frequency cell, only allow the user on main carrier frequency, to insert, if so require inaccessible main carrier frequency in the inaccessible request message, the base station should be changed to Primary Common Control Physical Channel (PCCPCH) and downlink pilot frequency channel (DWPCH) unavailablely after receiving inaccessible response so, stops new user to insert whole sub-district.If what inaccessible request message comprised is assistant carrier frequency, the base station just stops the emission of assistant carrier frequency after receiving inaccessible response so, simultaneously, Primary Common Control Physical Channel (PCCPCH) and DWPCH channel should be changed to unavailablely, other that allows still in this case just that new user inserts the sub-district be not by the carrier frequency of obturation.
See also shown in Figure 1, the present invention is based in the multi-carrier frequency cell of carrier frequency resource inaccessible with the embodiment that separates inaccessible implementation method, idiographic flow is as follows:
For seclusion, may further comprise the steps:
Step 1:NODEB (base station) some unusual (for example: radio frequency unit breaks down) occur if investigate, the emission of some carrier frequency in inaccessible certain sub-district is wanted in decision, require the logical resource of inaccessible corresponding carrier frequency so just send the inaccessible request message of resource to RNC, include the carrier frequency unit marks of corresponding carrier frequency in the resource obturation request message.
Step 2: after RNC receives the inaccessible request message of resource, behaviour in service according to own internal resource is judged, think and to carry out block service, again according to the logical resource of the inaccessible affected corresponding carrier frequency of carrier frequency unit marks in the inaccessible request message of resource, according to wanting inaccessible priority, remove the logical resource of corresponding carrier frequency correspondence, updating system information broadcasting then; After if RNC receives the inaccessible request message of resource, behaviour in service according to own internal resource is judged, if think and temporarily can not carry out block service at present, promptly respond the inaccessible failed message of resource to NODEB, need not be with the carrier frequency unit marks in the inaccessible failed message.After NODEB received the inaccessible failed message of resource, it is identical with block service state before that each logical resource should keep.
Step 3: give NODEB if RNC sends inaccessible response (BLOCK RESOURCE RESPONSE) message, after NODEB receives this message, stop the emission of corresponding CF signal.If comprise main carrier frequency in the inaccessible in addition response message, NOEDB should will stop the emission of the PCCPCH and the DWPCH channel of sub-district so, stops the user to insert whole sub-district.If do not comprise main carrier frequency in the inaccessible response message, NOEDB just should not be changed to PCCPCH and DWPCH channel unavailablely so, just still allows the user to insert in this case.
For separating obturation, may further comprise the steps:
Step 1: but the time spent become when the original inaccessible carrier frequency unit of NODEB, the NODEB background net management will be separated inaccessible this carrier frequency unit, it can begin the emission of corresponding CF signal, send then and separate inaccessible indication (UNBLOCK RESOURCE INDICATION) message, separate the request of including in the inaccessible Indication message and separate inaccessible carrier frequency unit marks to RNC.
Step 2:RNC receives and separates inaccessible indication (UNBLOCK RESOURCE INDICATION) message, separates inaccessible carrier frequency unit marks according to request, recovers corresponding affected logical resource.If RNC separates inside the block service failure, will guarantee that RNC is consistent with the resource status among the NODEB by AUDIT (resource audit) process subsequently.
