Description
Technical field
The present invention relates to the mobile communication technology field, be meant a kind of method of controlling the 3-G (Generation Three mobile communication system) service transmission rate especially.
Background technology
3-G (Generation Three mobile communication system) can be supported various types of multimedia services, comprises that maximum rate reaches the mutual or background service of 384 kilobits/second (384kbps) even 2 mbit/(2M bps).In general, under the same conditions, professional speed is high more, needs the system resource of consumption also just many more.Simultaneously, the system resource that is consumed also is subjected to the distance between travelling carriage and the base station and the influence of this travelling carriage surrounding environment, and promptly travelling carriage is far away more from the base station, and surrounding environment is strong more to the decline of signal, and then the system resource of Xiao Haoing is just many more, otherwise just few more.
Because the total resource of system is limited, especially therefore the power resource of base station, just relates to and how system resource is carried out this key issue of reasonable distribution.If in the abominable place of a certain environment, system is that a user sets up the business of speed up to 2M bps, then may cause the most resources in the system all to be consumed, and can not provide the necessary service or even the service of general speech business for other user by this user.Therefore, in order to prevent that some users to the consuming excessively or wasting of system resource, must carry out certain restriction to the business of its foundation.
In order effectively to distribute and the using system resource, normally used method is that the transmission rate of customer service is controlled, and particularly the transmission rate of the non-real-time service of some two-forties is controlled.For example, when the user is distant from the base station, the transmission rate of this customer service is lowered, thereby reduce of the consumption of this business to system resource, otherwise, when the user is closer from the base station, can improve the transmission rate of this customer service, because the reason that path loss is less, the transmitting power that the base station needs may still can keep a lower value.Like this, by rational control transmission speed, system just can distribute to Limited resources the user of varying environment different business, thereby improves the utilization ratio of system resource, has also improved the capacity of system simultaneously.
Realize the reasonable control to service rate, method commonly used is to control according to the size of the down transmitting power of business.Figure 1 shows that the flow chart based on transmitting power control transmission speed of prior art.
Though such scheme, has reduced professional consumption to the system power resource to a certain extent by the measurement of down transmitting power having been finished the rate controlled to customer service.But there are following problems:
1) do not take into full account the service efficiency of resource.Because data service has the characteristic of data source burst, in whole communication process, the data of transmission constantly change.To the measurement of down transmitting power, can only reflect the power of this user's actual consumption, but can not reflect the power resource utilization ratio of this user's reality.Therefore, such rate controlled promptly allows to reduce the consumption of user to resource, but when carrying out rate controlled, is the comparison blindness, can not control accurately according to the level of resources utilization of reality.Even in parameter configuration not at that time, probably reduced the level of resources utilization of system.
2) do not take into full account the difference of the level of resources utilization between the different user.Because the method for description of the Prior Art can not obtain certain user's real resource utilization ratio, therefore, can not carry out the control of otherness to different user according to the difference between the different user level of resources utilization.

Figure 2 shows that and use the flow chart based on level of resources utilization control transmission speed of the present invention.
Step 201 according to service request from user, is its minimum transmission rate (Rmin) of distributing initial transmission rate (R), peak transfer rate (Rmax) and satisfying its operation quality requirement (QoS);
Step 202, this user's maximum resource utilization ratio (Emax) and least resource utilization ratio (Emin) are set according to the concrete method for expressing of the level of resources utilization that sets in advance, and corresponding Upper threshold (Th) and Lower Threshold (Tl) are set for this user, set Emax, Emin, the method for expressing of Th and Tl is consistent with the concrete method for expressing of the level of resources utilization, and the value of Th and Tl arrives within the Emax scope at Emin, obtain the current level of resources utilization of this user (E), the current level of resources utilization of this user also is identical with the concrete method for expressing of the level of resources utilization that sets in advance;

Figure 3 shows that the flow chart that obtains the level of resources utilization.
Step 304, by the rate controlled module receive from the base station and or mobile station measurements, obtain the current level of resources utilization of user and representation thereof, and use its representation active user's the level of resources utilization is judged.
Above-mentioned speed rates process can be carried out rate controlled simultaneously at the uplink and downlink of a link, also can only carry out rate controlled at the upstream or downstream of a link.That is to say, if the level of resources utilization difference of uplink and downlink, the speed adjustment of up-downgoing also can be different, for example improve the transmission rate of up link, and the transmission rate of reduction down link perhaps, is only carried out rate controlled to the upstream or downstream of a link, for example, only reduce the transmission rate of down link.
The method of the level of resources utilization (E) of obtaining the user is a lot, and therefore, the method for the expression level of resources utilization is also a lot, lifts two kinds of simple methods at this:
Method one: path loss method.Promptly use the distance (L) between base station and the travelling carriage, as the representation of this user resources utilization ratio.If distance is big more, then path loss is big more, reach same received signal intensity, just need higher transmitting power, so this user has the lower level of resources utilization.Otherwise distance is more little, and then path loss is more little, so this user has than the higher level of resources utilization.Suppose in a certain sub-district, the minimum of path loss and maximum are respectively Lmin and Lmax, minimum and the maximum of then representing the user resources utilization ratio with Lmin and Lmax, accordingly, threshold T h that is disposed and Tl also represent with the distance between base station and the travelling carriage, and Th and Tl belong to Lmin within the Lmax scope, and Th represents the minimum range between base station and the travelling carriage, and Tl represents the ultimate range between base station and the travelling carriage.
Method two: for down link signal, can adopt pilot signal quality of reception method.Be the signal quality (S) of the pilot signal that receives of user application, as the representation of this user resources utilization ratio.Because pilot signal is to send with certain power from the base station, if the signal quality that the user receives is lower, show that then the residing environment of this user is more abominable, so this user's the level of resources utilization is lower.Otherwise,, show that then the residing environment of this user is better, so this user's the level of resources utilization is higher if the signal quality that the user receives is higher.Suppose in a certain sub-district, minimum and maximum that the user receives the signal quality of pilot signal are respectively Smin and Smax, minimum and the maximum of then representing the user resources utilization ratio with Smin and Smax, accordingly, threshold T h that is disposed and Tl also represent with the signal quality of the received pilot signal of user, and Th and Tl belong to Lmin within the Lmax scope, Th represents the better quality of signal value of the pilot signal that the user is received, and Tl represents the value that the signal quality of the pilot signal that the user is received is relatively poor.
From the annexation of user and base station, up link is similar substantially with the residing environment of down link, that is to say, the level of resources utilization that uplink downlink is corresponding respectively is close.Thus, when carrying out rate controlled,, also can carry out the control of transmission rate simultaneously to uplink downlink even only obtained the level of resources utilization of up link or down link.Processing can reduce some measurement signaling and processing procedures like this.For example, using pilot signal receiving quality method can be carried out the control of transmission rate after obtaining the level of resources utilization of down link simultaneously simultaneously to uplink downlink.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being made, is equal to and replaces and improve, and all should be included within protection scope of the present invention.
