Abstract

The invention provides a method and equipment for dynamically selecting UE speeds. A UE at the center of a cell adopts a larger access speed and users on the rim of the cell adopt lower access speeds so that upstream access speeds of users at the center zone can be modified and a KPI is not affected. Moreover, repeated configuration times of an RB are reduced and an access success rate and a call drop rate of a PS are modified.

Description

A kind of method and apparatus of Dynamic Selection UE speed

Technical field

The present invention relates to mobile communication technology, particularly a kind of method and apparatus of Dynamic Selection UE speed.

Background technology

In the TD-SCDMA system, in order to improve user's impression, and timely release code resource, each producer all adopts similar algorithms, by 4A and the 4B measurement event of stipulating in the agreement, judges user uplink or descending sign indicating number resource requirement, carry out raising speed and reduction of speed timely, thereby guarantee to satisfy user's sign indicating number resource requirement, unwanted sign indicating number resource can be discharged again, dynamically allocate resource.But adopt in such a way, user's RB (radio bearer) reprovision number of times will become many, and this will influence user impression, increase the call drop probability, and when the sign indicating number resource abundance of residential quarter, it is also nonsensical to carry out lifting speed frequently.

For solving the problems of the technologies described above, the modes such as initial access rate by improving the user and maximum rate of attempting in the industry satisfy rate requirement, and the measuring period by delaying 4B or increase the frequency that mode such as 4B times of reporting is slowed down reduction of speed, thereby reduce the dynamic adjustment number of times of user's RB reprovision, to promote user's impression.

But these methods have been brought following problem:

1, because the speed when inserting increases, causes the required code channel resource of user to increase, thereby cause the UE need be with bigger power emission, in case underpower just will cause user's access failure.

2, because in the middle of promoting or maximum rate, the slow mode of reduction of speed, it is more to cause UE to rest on time of big speed, in case UE moves to cell edge region, if the UE underpower just will cause call drop, influence the user and experiences, and causes the KPI deterioration.

3, adopt the mode of slow reduction of speed, can not in time the unwanted sign indicating number of user resource be discharged to other users, influence other users' professional and impression.

Embodiment

For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.

Main thought of the present invention is: to being positioned at the UE of center of housing estate, because path loss is lower, the UE transmitting power is enough, can adopt bigger access rate; And to being in the user of cell edge, if the transmitting power deficiency then adopts lower access rate, can improve central area user's up access rate like this, and can not impact KPI, and, can reduce RB and reshuffle number of times, and improve access success rate and the cutting off rate of PS.

Access comprises: the speed adjustment in the switching access of initial access, minizone, the access of the switching in the residential quarter and the residential quarter etc.

On this basis, a yard resource early warning thresholding can be set further, in order to monitoring the sign indicating number resources left situation in the residential quarter, and utilize relevant measurement event that the transmitting power of UE is monitored, in due course UE be carried out reduction of speed.And, can also utilize 6A and 6B measurement event, UE is carried out raising speed restriction or reduction of speed.

Fig. 1 is the schematic flow sheet of the method for the present invention's one preferable Dynamic Selection UE speed.Referring to Fig. 1, this method comprises:

Step 101: according to the path loss of UE, the UE lower to path loss improves the access rate of this UE; The UE higher to path loss reduces the access rate of this UE.

In this step, the path loss that can calculate UE based on power and the RSCP (received signal code power) of PCCPCH (Primary Common Control Physical Channel), and according to the maximum transmission power of UE, the path loss of UE and the ISCP (Interference Signal Code Power) of time slot n, the maximum that calculating makes the signal to noise ratio (SIR) of time slot n satisfy the UE of default SIR thresholding allows speed, and allows speed to determine the access rate of UE according to this maximum.

According to SIR _n=P _{UE_MAX}-(P _PCCPCH-RSCP _PCCPCH)-ISCP _n-10log (K/2)＞SIR _ThresholdCan release:

When UE switches to Target cell, obtain the PCCPCH RSCP value of Target cell by 1G or 2A measurement report, and calculate the maximum permission speed of UE according to formula (1); If the maximum speed that allows greater than the present rate of UE, then allows this UE to allow speed or present rate to insert with maximum, otherwise UE can only insert with the minimum value among both.

1G event: when UE measures the best cell change of same frequency, report this measurement event;

2A event: when UE measures the best cell change of alien frequencies, report this measurement event.

When during UE is calling out maintenance, attempting raising speed, obtain the RSCP value of the PCCPCH of nearest moment residential quarter by periodic measurement report, and calculate UE at time slot n during with the targeted rate emission of current application according to formula (1), whether the SIR that can reach satisfies default SIR thresholding, if satisfy, then allow this UE to insert with the targeted rate of current application; If do not satisfy, then selecting a speed as the targeted rate of the current application of UE greater than the UE present rate and in less than the speed of the targeted rate of the current application of UE, continue to carry out aforesaid operations, if be down to the UE present rate until the targeted rate of the current application of UE, still do not satisfy, then do not allow this UE to carry out raising speed.

Step 102: a yard resource early warning thresholding is set, when the residue available code resource is lower than yard resource early warning thresholding, if there is UE to report one or more 4B events, then this UE is carried out reduction of speed.

The 4A event: when the transmission channel traffic carrying capacity surpassed certain thresholding, UE reported this measurement event;

The 4B event: when the transmission channel traffic carrying capacity was lower than certain thresholding, UE reported this measurement event.

Step 103: if UE reports the 6A event, then record the present rate of UE, before receiving the 6B event, do not allow this UE raising speed to surpass the present rate that records; If after UE reports the 6A event, and before receiving the 6B event, receive the 4B event, then this UE carried out reduction of speed.

The 6A event: when the UE transmitted power surpassed certain thresholding, UE reported this measurement event;

The 6B event: when the UE transmitted power was lower than certain thresholding, UE reported this measurement event.

Corresponding to said method, the present invention also provides a kind of equipment of Dynamic Selection UE speed, and this equipment be used for to be judged the path loss of UE, and the UE lower to path loss improves the access rate of this UE; The UE higher to path loss reduces the access rate of this UE.
