Description

A kind of method and device thereof that improves user unloading speed
Technical field
The present invention relates to a kind of page download method and device, relate in particular to a kind of method and device thereof that improves downloading rate, it is few but the user experiences requirement than the method that improves page download speed in the higher place to be applied to user in the sub-district.
Background technology
3GPP (3G standard is formulated tissue and is called for short) WCDMA (Wideband Code Division Multiple Access (WCDMA)) R5 version has been introduced the higher access technology-high speed downlink packet of the availability of frequency spectrum and has been inserted (HSDPA) aspect wireless access network, make the R5 version can support the downstream data traffic of higher rate, strengthened greatly downlink data has been used as interactive class, the support of background classes and streaming media service.Just because of the humidification of HSDPA, make each operator to HSDPA (high speed downlink packet access) pay much attention to, all the indispensable function of HSDPA as 3G network.
The HSDPA technology can be brought the raising of the availability of frequency spectrum, thereby can obtain bigger throughput in the unit frequency spectrum.This point is determined, but the impression that how to utilize the HSDPA technology to improve the user under the R5 protocol frame then has a lot of approach, and effect also is not quite similar.
In the web page browsing process of a reality, the network download speed that the user experiences is relevant with numerous factors, and as shown in Figure 1: a complete webpage opening procedure comprises: wireless channel is set up, application layer messages is mutual, the slow start-up course of transport layer, data are downloaded.Carrying is compared with the DCH of R99 version, and the HSDPA carrying can be in the back improves user's perceptual speed in three processes: because the round-trip delay of HSDPA is littler than DCH, so application layer is mutual and the slow start-up course of TCP can comparatively fast be finished; Because the downloading rate of eating dishes without rice or wine of HSDPA is higher than DCH, so the time that it needs when downloading a webpage is short.But it is the same setting up the process HSDPA signaling procedure that carrying is to use with DCH for wireless channel, and the HSDPA technology itself has no idea to reduce its time delay.
In these four time phases, the proportion that wireless channel is set up is very large, especially for the little and frequent business model of the such packet of web page browsing.The time that wireless channel is set up generally is 4 seconds, and application layer is mutual, the slow start-up course of TCP approximately each 1 second, for the big webpage (little webpage generally has only 25Kbytes) of 60Kbytes, the HSDPA typical case urban area circumstance speed about 500kbps was downloaded also about 1 second.Wireless channel was set up and has been taken 4 seconds during 7 second download time of a session constituted, and reached about 60%; Even in addition the transfer rate several times of HSDPA are improved, can not obviously improve user's impression.
Summary of the invention
Technical problem to be solved by this invention provides a kind of method that improves user unloading speed, and it can make full use of the impression that Internet resources improve HSDPA user under the existing protocol framework, bigger influence can not arranged to the power system capacity of HSDPA again simultaneously.
Consider the continuity of web page browsing user network page browsing activity, if this channel is kept not discharging after wireless channel is set up in web page browsing first the user, making follow-up the browsing of user not need to carry out wireless channel sets up again, thereby greatly reduce the whole download time of subsequent web pages, improve the impression of user's download speed.Simultaneously can not keep this channel always, keep channel between the multi-user, to share, after certain hour, still will discharge this channel resource.
Based on above-mentioned theory, the invention provides a kind of method that improves the user side downloading rate, at first in radio network controller, set up a timer; The channel releasing device monitors the data transmission and finishes, and starts timer; Behind timer expiry, the channel releasing device discharges corresponding radio bearer channel.
Wherein, the value T of described timer is distributed by user's webpage and calculate reading time.Its value T is: the read time when getting 60%~95% accumulated probability, it is μ that described read time Dpc obeys average DpcGeometric distributions: Dpc ∈ GEOM (μ Dpc), the average value mu of this distribution DpcBe statistics, promptly people browse the statistical average time of a webpage usually.
Accordingly, the present invention also provides a kind of device that improves the user side downloading rate, comprising:
Timer is built in the radio network controller;
The channel releasing device is used to monitor data and sends when finishing, and starts timer, behind timer expiry, discharges corresponding radio bearer channel.
The present invention is not influencing under the situation of HSDPA power system capacity under the existing protocol framework, makes full use of the speed of download impression that Internet resources improve HSDPA user, bigger influence can not arranged to the power system capacity of HSDPA again simultaneously.The solution that can be used as a kind of characteristic for operator is used, and becomes the bright spot and the competitive advantage of network.
Description of drawings
Fig. 1 is a web page browsing process schematic diagram.
Fig. 2 adopts method of the present invention to carry out the process schematic diagram of network browsing.
Embodiment
As shown in Figure 2 be the business model schematic diagram that the user carries out network browsing, download corresponding one " Packet Call (web page browsing) " of webpage, download the back user that finishes and have a reading time, carrying out next webpage then.Based on the description of front, the invention provides a kind of method that improves user unloading speed, at first in radio network controller, set up a timer; The channel releasing device monitors the data transmission and finishes, and starts timer; Behind timer expiry, the channel releasing device discharges corresponding radio bearer channel.
The value T of timer is distributed by user's webpage and calculate reading time, in this specific embodiment, reading time under satisfied 90% the accumulated probability situation, 90% is the value of compromising between user's impression and the resource-sharing, according to also getting other values according to network planning needs, in general this value can get 60%~95%.It is μ that read time Dpc between packet is called out obeys average DpcGeometric distributions: Dpc ∈ GEOM (μ Dpc), get 90%, in general this value also can get 60%~95%.Read time during accumulated probability is a timer time, the average value mu of this distribution DpcBy providing in the network planning business model hypothesis.This average value mu DpcBeing statistics, generally is about one minute, is exactly the statistical average time that people browse a webpage usually.
Suppose that p is that a timeslice (being assumed to be 1 second) finishes the average probability that the back user finishes to read, the user at the probability that the reading of j timeslice finishes is so: Gemo (j)=p* (1-p) (j-1), j 〉=1.The time of supposing to read usually a webpage is 80s, p=1/80 so, and accumulated probability is that can to calculate this moment timeslice sequence number at 90% o'clock be j=184, and promptly can be set Dpc=184 second, that is to say that the value T that timer is set is 184 seconds.(DPC is exactly T)
Accordingly, the present invention also provides a kind of device that improves the user side downloading rate, comprises timer, is built in the radio network controller;
The channel releasing device is used to monitor data and sends when finishing, and starts timer, behind timer expiry, discharges corresponding radio bearer channel.
The setting of described timer makes the time lengthening of CU channel resource, thereby the number of users of supporting under same business model and cell channel resource situation will reduce, because the time of CU channel much larger than the time that data send, therefore can use the ErlangB formula to calculate the number of users of being supported.The average arrival rate of supposing each user network page browsing is a λ per second, (wherein λ can be calculated by the business model in the network planning speed 1/T that session an is left per second, the mean busy hour speed that for example provides the user in the business model is 1kbps, so for the average webpage size of common 60KBytes, each user have when busy λ=1kbps*3600/ (60k*8)=7.5 webpage/hour; When timer T value much larger than a webpage eat dishes without rice or wine can get session rate of departure=1/T during transmitting time.), in the sub-district, have M user simultaneously the blocking probability during cell configuration N bar channel be B, regulate M according to the ErlangB formula and make the blocking probability that B meets the demands, thereby calculate M.λ wherein, the number of channel N that blocking probability requires, equipment provides provide in the hypothesized model of the network planning.
B = ( λ * M * T ) N / N ! Σ k = 0 k = N ( λ * M * T ) k / k !
From top description as can be seen this scheme be suitable in the sub-district user's few (being suitable for little peak nest and skin honeycomb) but the user experiences requirement than higher place.And various indoor, club's scenes just in time satisfy, and the characteristic solution class that therefore can be used as a kind of HSDPA is used.
