Below in conjunction with accompanying drawing the preferred embodiment of the present invention is elaborated.
Consult shown in Figure 1ly, in the embodiment of the invention, it is as follows that the server (hereinafter referred to as the 3G server) of management 3G network covers the exemplary flow assess to 3G network:
When user's calling parameter that step 100:3G server basis is obtained determines that with default network configuration parameters existence switches to the 3G subscription of 2G network by 3G network, the value W of the covering performance parameter of 3G network when obtaining the switching of generation network according to this user's calling parameter.
In the embodiment of the invention, the 3G server can pass through HSS(Home Subscriber Server, home signature user server) obtains user's calling parameter, this user's calling parameter can include but not limited to: the call bill data of user in 3G network and 2G network, for example: user ID, calling takies the residential quarter, the duration of call, the value of the covering performance parameter of the 3G network that periodic measurement obtains and number of samples etc., and the 3G server can be determined the current network environment by network configuration parameters or the high-rise network configuration parameters that issues of local initial configuration, this network configuration parameters can include but not limited to: the coverage of 3G network and 2G network and adjacent area corresponding relation, for example: the cell ID of each 3G residential quarter and 2G cell, the subdistrict position district, put etc. switching time, can also comprise the report cycle of the covering performance parameter of configuration in the network configuration parameters.Like this, the 3G server is in conjunction with user's call data and network configuration parameters, can determine whether namely that according to the call bill data in the 3G network existence switches to the 3G subscription of 2G network from 3G network, and according to the adjacent area corresponding relation of 3G network and 2G network, can determine to switch to the target 2G cell at the current place of 3G subscription of 2G network, and obtain this 3G subscription at the call bill data of 2G network according to the identification information of this target 2G cell.
After definite 3G subscription switches to the 2G network from 3G network, the value W of the covering performance parameter of 3G network when the 3G server can also determine that network occurs to be switched according to the call bill data of the 3G network that carries in the user's call data that obtain, wherein, so-called covering performance parameter, better, can be PCCPCHRSCP(Primary Common Control Physical Channel Received Signal Code Power, the Common Control Physical Channel received signal code power).
The value W of the covering performance parameter of 3G network generated the simulation covering performance parameter of the first number of samples when step 110:3G server switched based on the generation network, and according to number and first number of samples of the adjacent 3G residential quarter of the target 2G cell at place after switching with 3G subscription, determine the number of samples of the simulation covering performance parameter that the 3G residential quarter adjacent with above-mentioned target 2G cell is corresponding.
Be specially: the 3G network server determines that according to the identification information of user's calling parameter and the current place of 3G subscription 2G cell this 3G subscription is at the call bill data of 2G network, and determine the duration of call T of 3G subscription in the target 2G cell according to this call bill data, and the report cycle I that determines the covering performance parameter of default 3G network according to network configuration parameters, then, it is that Z and value are the simulation covering performance parameter of W ' that the 3G server generates number of samples, wherein, W '=W
Z namely is above-mentioned the first number of samples, is also referred to as number of samples, and by execution in step 110, the 3G server has generated Z the simulation covering performance parameter that value is W '.Like this operation, purpose are that the duration of call of 3G subscription in the target 2G cell is converted to the simulation covering performance parameter of respective sample number according to the report cycle of covering performance parameter, use for the follow-up 3G network coverage evaluating of carrying out.
Then, the 3G server determines that the number of samples of the simulation covering performance parameter that each 3G residential quarter adjacent with above-mentioned target 2G cell is corresponding is Z ', wherein,
X is the number of the 3G residential quarter adjacent with above-mentioned target 2G cell; Be that each 3G residential quarter adjacent with above-mentioned 2G cell is all to there being the individual simulation covering performance of Z ' parameter.
Further, determine that 3G subscription continues to switch to other target 2G cells by current place target 2G cell, then the 3G server can adopt same way as to generate the simulation covering performance parameter of the second number of samples (consistent with the first number of samples account form) based on the value W of covering performance parameter, and according to switch after number of samples and second number of samples of the adjacent 3G residential quarter of other target 2G cells, determine the number of samples (account form and aforementioned manner are identical) of the simulation covering performance parameter that the 3G residential quarter adjacent with above-mentioned other target 2G cells is corresponding; Wherein, if exist simultaneously with switch before and after the adjacent 3G residential quarter of target 2G cell, then the 3G server can superpose each time to the number of samples that should the 3G residential quarter calculates the simulation covering performance parameter of acquisition.
Step 120:3G server is the covering performance parameter of W and the number of samples ratio of calculating the simulation covering performance parameter that obtains according to value corresponding to each 3G residential quarter respectively, and the coverage condition of corresponding 3G residential quarter is assessed.
(hereinafter referred to as 3G residential quarter X) is as example take any one 3G residential quarter, the 3G server determines that according to user's calling parameter all values of corresponding 3G residential quarter X record are the number of samples z of the covering performance parameter of W first, and the value of determining corresponding 3G residential quarter X record is the number of samples Z ' of the simulation covering performance parameter of W ', then, calculate the ratio A of z and Z ', and the value of A and default covering grade and the corresponding relation between the ratio value mated, according to matching result the network coverage status of 3G residential quarter X is assessed.
The below makes further description by a concrete application scenarios to above-described embodiment take the covering performance parameter as PCCPCH RSCP as example, specifically as shown in Figure 2:
Step 200:3G server importing user call data (as, the user is at the call bill data of 3G network and 2G network) and default network configuration parameters.
In the embodiment of the invention, user's call data mainly comprise: call out the value that takies residential quarter, the duration of call, periodic measurement PCCPCH RSCP; Network configuration parameters mainly comprises the neighboring BS relationship of 2G cell and 3G residential quarter etc. information;
Step 201:3G server judges whether to exist the 3G subscription that is switched to the 2G network by 3G network according to the call bill data of the 3G network that carries in the user's call data that obtain, if then carry out step 202; Otherwise, carry out step 211.
The 3G server can judge whether according to the call bill data of 3G network to exist the suddenly ticket of interruption of conversation, when determining to have this type of ticket, can judge first that 3G subscription corresponding to this type of ticket switched to the 2G network, because, critical edges at 3G network and 2G network, if the signal of 2G network is better than 3G network, 3G subscription can switch to the 2G network voluntarily.
For example: consult shown in Figure 3ly, suppose that 3G subscription at 3G residential quarter A, in moving process, can switch to 2G cell 1.
Step 202:3G server is for the 3G subscription that network switches, the value W of the PCCPCH RSCP of 3G network when record switches have occured.
Step 203:3G server is searched the call bill data of this 3G subscription in the 2G network according to the user totem information of 3G subscription and the identification information of the target 2G cell after the switching.
Be that the 3G server is according to the LAC(location area code of target 2G cell, the lane place), the user ID of cell ID (being Cell ID) and 3G subscription (as, IMSI(International Mobile Subscriber Identity, international mobile subscriber identification code) or TSMI(Temporary MobileSubscriber Identity, the Temporary Mobile Subscriber Identity code)) and switching time point, search 3G subscription and switch to the call bill data that produces behind the target 2G cell.
Does step 204:3G server judge whether to find 3G subscription at the call bill data of target 2G cell? if then carry out step 205; Otherwise, carry out step 211.
Step 205:3G server obtains 3G subscription at the duration of call T of this target 2G cell according to 3G subscription at the call bill data of 2G network.
Step 206:3G server according to 3G subscription in the target 2G cell duration of call T and the 3G network of configuration in the report cycle I of PCCPCH RSCP, calculate the number of samples Z of simulation PCCPCH RSCP.
Step 207:3G server judges according to network configuration parameters whether the target 2G cell at 3G subscription place exists adjacent 3G residential quarter; If, then carry out step 208, otherwise, carry out step 210.
For example, suppose that 3G subscription is current at 2G cell 1, then the 3G server can determine that according to network configuration parameters its adjacent 3G residential quarter is 3G residential quarter A and 3G residential quarter B; Perhaps, suppose 3G subscription at 2G cell 2, then the 3G server determines that according to network configuration parameters only there is 3G residential quarter B its adjacent 3G residential quarter.
The number of samples X of the 3G residential quarter that step 208:3G server statistics is adjacent with the target 2G cell.
Step 209:3G server calculates the number of samples Z ' of simulation PCCPCH RSCP corresponding to each 3G residential quarter according to the number X of the number of samples Z of simulation PCCPCH RSCP and the 3G residential quarter adjacent with the target 2G cell.
Does step 210:3G server judge that 3G subscription switches to another target 2G cell from current target 2G cell? do you (judge that namely the switching in the 2G network has occured 3G subscription? if), then return step 203; Otherwise, carry out step 211.
The 3G server can judge whether 3G subscription the switching between the 2G cell has occured again according to the call bill data of 3G subscription, for example, 3G subscription switches to 2G cell 2 from 2G cell 1, at this moment, 2G cell 1 and 3G residential quarter A and 3G residential quarter B are adjacent, and 2G cell 2 is adjacent with 3G residential quarter B, as seen, behind the number of samples Z ' 1 that calculates simulation PCCPCH RSCP corresponding to 3G residential quarter B based on 2G cell 1, also need to calculate based on 2G cell the number of samples Z ' 2 of simulation PCCPCH RSCP corresponding to 3G residential quarter B, and when 3G residential quarter B being carried out network coverage assessment, the above-mentioned number of samples Z ' 1 of comprehensive reference and Z ' 2.
Step 211:3G server is the PCCPCHRSCP of W and the number of samples ratio of calculating the simulation PCCPCH RSCP that obtains according to value corresponding to each 3G residential quarter respectively, and the network coverage status of corresponding 3G residential quarter is assessed.
For example, suppose that value corresponding to 3G residential quarter C is that the number of samples z of the PCCPCH RSCP of W is 10, and the number of samples Z ' of the simulation PCCPCH RSCP that calculating corresponding to 3G residential quarter C obtains is 0, be that its number of samples ratio is 10:0, so, the 3G server can determine that the network coverage status of 3G residential quarter C is " excellent ".
Again for example, suppose that value corresponding to 3G residential quarter A is that the number of samples z of the PCCPCH RSCP of W is 10, and the number Z ' of the simulation PCCPCH RSCP that calculating corresponding to 3G residential quarter A obtains is 5, be that its number of samples ratio is 10:5, so, the 3G server can determine that the network coverage status of 3G residential quarter A is " very ".And if not with reference to the number Z ' that calculates the simulation PCCPCH RSCP that obtains, then the 3G server may determine that the network coverage status of 3G residential quarter A is " excellent ", thereby can't know that the situation of overburden depth deficiency will appear in 3G residential quarter A.
Again for example: suppose that value corresponding to 3G residential quarter B is that the number of samples z of the PCCPCH RSCP of W is 10, and the number of samples of the simulation PCCPCH RSCP that calculating corresponding to 3G residential quarter B obtains (Z ' 1+Z ' 2) be 9, be that its number of samples ratio is 10:9, so, the 3G server can determine that the network coverage status of 3G residential quarter B is " poor ".And if not with reference to the number of the simulation PCCPCH RSCP that calculate to obtain (Z ' 1+Z ' 2), then the 3G server may determine that the network coverage status of 3G residential quarter B is " excellent ", thereby can't know that the situation of overburden depth deficiency has appearred in 3G residential quarter B.
Other assessment modes all can be analogized with reference to aforesaid way, give unnecessary details no longer one by one at this.
Certainly, the value of above-mentioned number of samples ratio and the corresponding relation between the network coverage status can be summarized actual application environment and be arranged flexibly, and above-mentioned record is only for giving an example.
On the other hand, process if directly go to step 211 by step 202, then be considered as in the case 3G network not occuring to the switching of 2G network, so, when execution in step 211, the number of samples of the simulation PCCPCH RSCP that the 3G server can be corresponding with the 3G residential quarter is designated as 0;
If process and directly go to step 211 by step 204, then be considered as in the case 3G subscription and do not use business (being that the target 2G cell can not disturb adjacent 3G residential quarter) at the 2G network, so, when execution in step 212, the number of samples of the simulation PCCPCH RSCP that the 3G server can be corresponding with the 3G residential quarter is designated as 0.
