Embodiment
In the embodiment of the invention, when NodeB determines to be adjusted into the HS-SCCH of UE configuration and/or HS-SICH resource, directly will be carried in the radio link parameter update request, send to RNC for HS-SCCH and/or the HS-SICH resource information that UE reconfigures.When RNC receives this update request, directly initiate the physical channel reconfiguration course, and then be embodied as the HS-SCCH of UE configuration and the adjustment of HS-SICH resource.
Fig. 1 is the flow chart of resource adjusting method embodiment of the present invention, and this flow process comprises the steps:
Step 101 when NodeB determines to be adjusted into the HS-SCCH of UE configuration and/or HS-SICH resource, sends the radio link parameter update request to RNC, and carrying NodeB in this request is HS-SCCH and/or the HS-SICH resource information that UE reconfigures.
Here, NodeB can determine whether to be adjusted into the HS-SCCH and/or the HS-SICH resource of UE configuration according to the UE current wireless link ambient conditions of self adding up at present.Such as, NodeB can determine whether to be adjusted into the HS-SCCH and/or the HS-SICH resource of UE configuration according to the current data transmission efficiency of UE.
Perhaps NodeB can determine whether to be adjusted into the HS-SCCH and/or the HS-SICH resource of UE configuration according to wireless environment to the interference power that UE causes.
Perhaps NodeB can determine to be adjusted into the HS-SCCH and/or the HS-SICH resource of UE configuration when configuration breaks down for the HS-SCCH of UE and/or HS-SICH resource can't to work.
Perhaps, shared NodeB by too many user when finding HS-SCCH and/or the HS-SICH resource of distributing to UE, cause the scheduling of resource difficulty, and also have comparatively idle HS-SCCH and/or HS-SICH resource simultaneously, then NodeB can determine to be adjusted into the HS-SCCH and/or the HS-SICH resource of UE configuration.
In addition, NodeB is that the HS-SCCH and the HS-SICH resource of UE configuration all occurs in pairs, and NodeB can dispose a pair ofly for UE, also can dispose many to HS-SCCH and HS-SICH resource.When needs when UE sends data, NodeB will distribute to the physical resource information notice UE of UE by a HS-SCCH who distributes to this UE; After UE received data, the HS-SICH by this HS-SCCH correspondence was to NodeB return data reception result and channel quality indication.
In this step, when NodeB is adjusted into the HS-SCCH of UE configuration and/or HS-SICH resource, can be adjusted into the one or more pairs of HS-SCCH and the HS-SICH resource of UE configuration, we can say that also NodeB can be adjusted into all or part of HS-SCCH and the HS-SICH resource of UE configuration.Such as NodeB is that UE has disposed two couples of HS-SCCH and HS-SICH resource, if NodeB finds in wherein a pair of HS-SCCH and the HS-SICH resource, one or all break down in the time of can't using, NodeB can be adjusted into the UE configuration this to HS-SCCH and HS-SICH resource; Shared by a lot of UE if NodeB is found to be a pair of HS-SCCH and the HS-SICH resource that UE distributes, cause scheduling of resource efficient to reduce, then NodeB can determine to be adjusted into the UE configuration this to HS-SCCH and HS-SICH resource.
And described a pair of HS-SCCH and the HS-SICH resource that is adjusted into UE configuration can be adjusted among a pair of HS-SCCH of UE configuration and the HS-SICH one for: NodeB, or all.Such as determining that the HS-SCCH in a pair of HS-SCCH and the HS-SICH resource breaks down as NodeB, then can adjust with this to the corresponding HS-SCCH of HS-SICH in HS-SCCH and the HS-SICH resource; Also can dispose a pair of HS-SCCH and HS-SICH resource for UE again.Specifically how to adjust, determine according to resource distribution situation at that time.
If NodeB has only disposed a pair of HS-SCCH and HS-SICH resource for UE, and NodeB determines only to need to adjust one of them channel resource, when then NodeB HS-SCCH that will reconfigure for UE and/or HS-SICH resource sent to RNC, a channel resource information that can only will reconfigure was carried in the radio link parameter update request and sends to RNC.Usually, NodeB needs the HS-SCCH and/or the HS-SICH resource that will reconfigure for UE, offers RNC in couples, to guarantee each corresponding relation to HS-SCCH and HS-SICH resource.
Step 102 after RNC receives radio link parameter update request from NodeB, is initiated the physical channel reconfiguration course.
Specifically comprise: RNC is with the HS-SCCH that reshuffles and/or the corresponding UE of HS-SICH resource information notice that carry in the radio link parameter update request that receives; After UE receives this notice, carry out physical channel and reshuffle, and return physical channel to RNC and reshuffle success or failure response message.
Step 103, RNC reshuffles response message according to the physical channel that UE returns, and judges whether radio link parameter update is successful, and sends the radio link parameter update response to NodeB.
If RNC receives the physical channel that UE returns and reshuffles successful respond information, then RNC determines the radio link parameter update success, send the radio link parameter update success response to NodeB, carrying in this success response is the new HS-SCCH that disposes of UE and/or the configuration take-effective opportunity of HS-SICH resource.Usually, this can be reshuffled in Connection Frame Number (CFN) field that is carried at the radio link parameter update success response opportunity of coming into force.
If RNC receives the physical channel reconfiguration failure response message that UE returns, then RNC determines the radio link parameter update failure, send the radio link parameter update failure response to NodeB, and RNC can further carry failure cause in the radio link parameter update failure response that returns to NodeB.
In addition, if behind RNC the UE that the HS-SCCH that reshuffles and/or HS-SICH resource information notice is corresponding, in setting-up time length, do not receive that always the physical channel that UE returns reshuffles response message, then RNC determines the radio link parameter update failure, send the radio link parameter update failure response to NodeB, and RNC can further carry failure cause in this failure response.
Also have a kind of special circumstances to need explanation, after RNC receives radio link parameter update request from NodeB, find the HS-SCCH that reconfigures and/or the HS-SICH resource of carrying in this request, the Radio Link of corresponding UE is released, then RNC directly returns the radio link parameter update failure response to NodeB, and can carry failure cause in this response.
