Step 305, according to user's detailed record of surfing the Net, determine and cause the poor GPRS network problem of user's quality of service used.
Concrete, obtain the state of user's online by field 5, obtain the data transmission performance in the upper network process of user by field 15,16,17.For example, when user surf the Net failure, data transmission performance poor (retransmission rate higher than 10%, downloading rate is lower than 50kbps), in conjunction with field 18 ~ 22 fixer network problems.Concrete grammar is as follows:
If 18 numbers of field are greater than 0, the wireless coverage existing problems of community, user place are described in the upper network process of user;
If 19 numbers of field are greater than 0, the local resource heavy congestion of user place is described in the upper network process of user;
If 20 numbers of field are greater than 0, illustrate in the upper network process of user,
If 21 numbers of field are greater than 0, illustrate that in the upper network process of user, community, the user place poor downlink transfer that causes of overlay environment is of poor quality;
If 22 numbers of field are greater than 0, illustrate that in the upper network process of user, user place subzone network state exists abnormal.
In addition, to reflect that user uploads each time or field 5 and the field 15 of the quality of service of downloading process, upload each time with reflection user respectively or downloading process in the field 18 to 22 of the Network Abnormal that occurs carry out correlation analysis, thereby determine and cause the poor GPRS network problem of user's quality of service used;
For example, user unloading speed (field 15) in the detailed record of analysis user online and the correlation of wireless connections loss number of times (field 20), the diamond block of Fig. 4 represents a user's wireless connections loss number of times and user unloading speed, as seen in Figure 4 along with the decline of user unloading speed, wireless connections are lost number of times and be there is no obvious increase, illustrate that between user unloading speed and wireless connections loss number of times, correlation is not high, therefore wireless connections loss is not the main cause that causes user unloading speed low.
The above, be only preferred embodiment of the present invention, is not intended to limit protection scope of the present invention.
