Embodiment
Basic thought of the present invention is: when distributing RU for DPCH, if idle RU can satisfy the requirement of described DPCH, just idle RU is distributed to described DPCH; When idle RU can't satisfy requiring of described DPCH,, then distribute idle RU and can take RU and give described DPCH if the idle RU and the resource summation that can take RU can satisfy the requirement of described DPCH.
For making those skilled in the art understand the present invention better, be further described in detail below in conjunction with specific embodiment.
Fig. 1 is the flow chart of embodiment 1.
In the time need distributing RU, promptly can trigger the method for embodiment 1 for new DPCH.
Wherein, when needs are set up new Radio Link, or when carrying out radio link reconfiguration, all needing is that new DPCH distributes RU.
In step 101, judge whether idle RU can satisfy the requirement of DPCH.
If idle RU can satisfy the requirement of described DPCH, then in step 102, distribute idle RU to give described DPCH.
If idle RU can't satisfy the requirement of described DPCH, then in step 103, can idle RU and the resource summation that can take RU satisfy the requirement of described DPCH.
The Provisioning Policy that can take RU has a lot, and a kind of strategy is that the RU that distributes to HS-PDSCH is set to take RU.Another kind of strategy is pre-configured RU set, when needs take RU, to be assigned to the RU of HS-PDSCH as taking RU in this RU set.
The third strategy is that the unnecessary RU that distributes to HS-PDSCH is set to take RU.
In actual applications, to the RU of HS-PDSCH distribution greater than the HSDPA business demand, this part RU greater than the HSDPA business demand that distributes to HS-PDSCH is called unnecessary RU sometimes.
Do you so, how to judge that HS-PDSCH has been assigned with unnecessary RU? can judge whether HS-PDSCH has been assigned with unnecessary RU, and judgment condition can be provided with one or more according to the judgment condition that presets.When a plurality of judgment condition is set, have only and satisfy all judgment condition, could determine that HS-PDSCH has been assigned with unnecessary RU.
Be that example describes so that a judgment condition to be set below.
As Rule of judgment, when setting up each HSDPA business in the sub-district, can determine the professional needed service rate summation Vreq of all HSDPA with the HSDPA service rate.If distribute to service rate summation Vru that the RU of HS-PDSCH can reach greater than Vreq, show that then this HS-PDSCH has been assigned with unnecessary RU.
As can be seen, also can other parameter as judgment condition, specifically adopt which parameter or what parameters should decide according to specific requirement as judgment condition, repeat no more here.
If idle RU and the resource summation that can take RU can satisfy the requirement of described DPCH, then in step 104, distribute idle RU and can take RU and give described DPCH.
Distributing idle RU for DPCH and can take RU the time, can the idle RU of priority allocation, that is, all idle RU are distributed to DPCH.Not enough part is replenished by taking RU.
When distributing idle RU for DPCH and can take RU, also can priority allocation can take RU, that is, all RU that takies are distributed to DPCH.Not enough part is replenished by idle RU.But this method of salary distribution is very big to the influence of other business, does not therefore recommend to adopt this method of salary distribution.
If idle RU and the resource summation that can take RU can't satisfy the requirement of described DPCH, then in step 105, distribute RU for described DPCH, return failure information.
Adopt embodiment 1 described method, when idle RU can't satisfy requiring of DPCH,, can distribute idle RU and can take RU and give described DPCH if satisfy condition.Thereby improved the success rate of distributing RU for DPCH.When the RU that takies when having distributed to the unnecessary RU of HS-PDSCH, can also improve the utilance of RU effectively.
But for the quality of the business of the occupied RU of The Long-term Effect (for example HSDPA business) not, DPCH be temporary transient to taking of RU.When new idle RU, DPCH should be adjusted to new idle RU, the RU of release busy, the business of returning occupied RU from the RU that takies.Below, 2 pairs of these methods specify in conjunction with the embodiments.Fig. 2 is the flow chart of embodiment 2.
Compare with flow process shown in Figure 1, in Fig. 2, increased the process that RU adjusts.Step 201 among Fig. 2～step 205 is identical with rapid 101～step 105 among Fig. 1.
After step 204, when new idle RU (step 206), judge whether new idle RU equals or more than the employed RU of taking of certain DPCH (step 207).
When a plurality of uses can take the DPCH of RU, described a plurality of DPCH are ranked, successively each DPCH is judged then.
Wherein, can rank to described a plurality of DPCH, perhaps in chronological order described a plurality of DPCH be ranked, also can rank to described a plurality of DPCH by other parameter by the quantity that takies RU.
If new idle RU equals or more than the employed RU of taking of certain DPCH, then can distribute new idle RU to give this DPCH (step 208).
If new idle RU less than the employed RU that takies of any one DPCH, does not then distribute new idle RU can take the DPCH (step 209) of RU to any one use.
After new idle RU distributed to the DPCH that certain use can take RU, (Dynamic Channel Allocation DCA) can adjust to new idle RU from the taken RU of its use with described DPCH by existing dynamic channel allocation.
After DPCH adjusted to new idle RU from the taken RU of its use, the employed RU of taking of DPCH was released.The described RU of taking should be used to its original business (for example HSDPA business) again.
In the TDD system, the scope of DCA can be at least a in frequency, time slot, the code channel.Can finish the DCA process by following step:
RNC sends radio link reconfiguration and prepares (Radio Link Reconfiguration Prepare) message to Node B, and notice Node B prepares radio link reconfiguration;
Node B returns radio link reconfiguration ready (Radio Link ReconfigurationReady) message to RNC, and RNC is ready for notice;
After RNC learns that Node B is ready, send radio link reconfiguration and submit to (Radio LinkReconfiguration Commit) message to give Node B.So far, finish the DCA process.
In the TDD system, can prepare message by radio link reconfiguration frequency, time slot, the code channel of Radio Link are reshuffled.
In embodiment 2 described methods, when new idle RU, preferentially new idle RU is distributed to the DPCH that use can take RU.In actual applications, also can priority allocation give new DPCH.When new idle RU can not be assigned to new DPCH, newer idle RU is distributed to the DPCH that use can take RU.
If pay the utmost attention to new idle RU is distributed to new DPCH, then when new idle RU (step 206), judge that can new idle RU satisfy the requirement of new DPCH.
Wherein, a plurality of if new DPCH has, then earlier described a plurality of DPCH are ranked, successively each DPCH is judged then.
Wherein, can rank to described a plurality of DPCH by the demand of RU, or in chronological order described a plurality of DPCH be ranked, also can rank to described a plurality of DPCH by other condition.
If new idle RU can satisfy the requirement of certain new DPCH, then new idle RU is distributed to this DPCH; If new idle RU can't satisfy the requirement of any one new DPCH, then judge and new idle RU can be distributed to the DPCH (step 207) that certain takies RU.
When new idle RU can't satisfy requiring of any one new DPCH, also execution in step 207 but remake further judgement not.Judge that can new idle RU and the resource summation that can take RU satisfy the requirement of certain new DPCH.
If new idle RU and the resource summation that can take RU can satisfy the requirement of certain new DPCH, then will new idle RU with can take RU and distribute to this DPCH;
If new idle RU and the resource summation that can take RU can't satisfy the requirement of any one new DPCH, then execution in step 207.
In above-mentioned two embodiment, RNC is after described DPCH distributes RU, can be by relevant message, and for example Radio Link is set up message or radio link reconfiguration message, with the RU information notice Node B that distributes.Node B will at first judge on the RU that distributes whether carrying out a certain business (for example HSDPA business), if then stop this current business.Then, described RU is used for described DPCH.
Based on said method, the present invention also provides a kind of device of DPCH Resources allocation that is.Fig. 3 is the structural representation of this device, and this device comprises: the first judging unit S31, the first allocation units S32, the second judging unit S33 and the second allocation units S34.
When needs are set up new Radio Link, or when carrying out radio link reconfiguration, all needing is that new DPCH distributes RU.When distributing RU, at first utilize the first judging unit S31 to judge whether idle RU can satisfy the requirement of DPCH for DPCH.
If idle RU can satisfy the requirement of described DPCH, then the first allocation units S32 distributes to described DPCH with idle RU.
If idle RU can't satisfy the requirement of described DPCH, then the second judging unit S33 judges that can idle RU and the resource summation that can take RU satisfy the requirement of described DPCH.
The Provisioning Policy that can take RU has a lot, and a kind of strategy is that the RU that distributes to HS-PDSCH is set to take RU.Another kind of strategy is pre-configured RU set, when needs take RU, to be assigned to the RU of HS-PDSCH as taking RU in this RU set.
The third strategy is that the unnecessary RU that distributes to HS-PDSCH is set to take RU.
In actual applications, to the RU of HS-PDSCH distribution greater than the HSDPA business demand, this part RU greater than the HSDPA business demand that distributes to HS-PDSCH is called unnecessary RU sometimes.
Do you so, how to judge that HS-PDSCH has been assigned with unnecessary RU? can judge whether HS-PDSCH has been assigned with unnecessary RU, and judgment condition can be provided with one or more according to the judgment condition that presets.When a plurality of judgment condition is set, have only and satisfy all judgment condition, could determine that HS-PDSCH has been assigned with unnecessary RU.
If idle RU and the resource summation that can take RU can satisfy the requirement of described DPCH, then the second allocation units S34 distributes idle RU and can take RU and gives described DPCH.If idle RU and the resource summation that can take RU can't satisfy the requirement of described DPCH, distribute RU then for described DPCH, return failure information.
Adopt device shown in Figure 3, when idle RU can't satisfy requiring of DPCH,, can distribute idle RU and can take RU and give described DPCH if satisfy condition.Thereby improved the success rate of distributing RU for DPCH.When the RU that takies when having distributed to the unnecessary RU of HS-PDSCH, can also improve the utilance of RU effectively.
But for the quality of the business of the occupied RU of The Long-term Effect (for example HSDPA business) not, DPCH be temporary transient to taking of RU.When new idle RU, DPCH should be adjusted to new idle RU, the RU of release busy from the RU that takies.Below, specify in conjunction with the device of Fig. 4.
Compare with device shown in Figure 3, device shown in Figure 4 has increased the 3rd judging unit S41 and the 3rd allocation units S42.
When new idle RU, the 3rd judging unit S41 will judge whether new idle RU equals or more than the employed RU of taking of certain DPCH.
When a plurality of uses can take the DPCH of RU, described a plurality of DPCH are ranked, successively each DPCH is judged then.
Wherein, can rank to described a plurality of DPCH, perhaps in chronological order described a plurality of DPCH be ranked, also can rank to described a plurality of DPCH by other parameter by the quantity that takies RU.
If new idle RU equals or more than the employed RU of taking of certain DPCH, then the 3rd allocation units S42 distributes to this DPCH with new idle RU.
If new idle RU less than the employed RU that takies of any one DPCH, then can't distribute to the DPCH that any one use can take RU with new idle RU.
In device shown in Figure 4, when new idle RU, preferentially new idle RU is distributed to the DPCH that use can take RU.In actual applications, also can priority allocation give new DPCH.When new idle RU can not be assigned to new DPCH, newer idle RU is distributed to the DPCH that use can take RU.Specify below in conjunction with Fig. 5.
Compare with device shown in Figure 4, device shown in Figure 5 has increased by the 4th judging unit S51.
When new idle RU, the 4th judging unit S51 will judge that can new idle RU satisfy the requirement of new DPCH, if can, then trigger the first allocation units S32; Otherwise, trigger the 3rd judging unit S41.
Wherein, a plurality of if new DPCH has, then earlier described a plurality of DPCH are ranked, successively each DPCH is judged then.
Wherein, can rank to described a plurality of DPCH by the demand of RU, or in chronological order described a plurality of DPCH be ranked, also can rank to described a plurality of DPCH by other condition.
In device shown in Figure 5, can also increase by one the 5th judging unit.When the 4th judging unit S51 judgement learnt that new idle RU can't satisfy requiring of any one DPCH, the 5th judging unit can judge further that can new idle RU and the resource summation that can take RU satisfy the requirement of certain new DPCH.If, can, then trigger the second allocation units S34; Otherwise, trigger the 3rd judging unit S41.
Described device is after DPCH distributes RU, and RNC can be by relevant message, and for example Radio Link is set up message or radio link reconfiguration message, with the RU information notice Node B that distributes.Node B will at first judge on the RU that distributes whether carrying out a certain business (for example HSDPA business), if then stop this current business.Then, described RU is used for described DPCH.
