Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is described in detail.
Consult shown in Fig. 1, in the embodiment of the present invention, to cover to 3G network the exemplary flow assessed as follows for the server (hereinafter referred to as 3G server) of management 3G network:
When step 100:3G server determines that existence switches to the 3G subscription of 2G network by 3G network according to the user's calling parameter obtained and the network configuration parameters of presetting, obtain the value W of the covering performance parameter that 3G network when network switches occurs according to this user's calling parameter.
In the embodiment of the present invention, 3G server can pass through HSS(Home Subscriber Server, home signature user server) obtain 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, such as: user ID, calling takies community, the duration of call, the value and number of samples etc. of the covering performance parameter of the 3G network that periodic measurement obtains, and the network configuration parameters determination current network conditions that 3G server can be issued by the network configuration parameters of local initial configuration or high level, this network configuration parameters can include but not limited to: the coverage of 3G network and 2G network and adjacent area corresponding relation, such as: the cell ID of each 3G community and 2G cell, subdistrict position district, switching time puts etc., the report cycle of the covering performance parameter of configuration can also be comprised in network configuration parameters.Like this, 3G server is in conjunction with user's call data and network configuration parameters, namely can determine whether to there is the 3G subscription switching to 2G network from 3G network according to the call bill data in 3G network, and according to the adjacent area corresponding relation of 3G network and 2G network, the target 2G cell at the current place of 3G subscription being switched to 2G network can be determined, and obtain the call bill data of this 3G subscription at 2G network according to the identification information of this target 2G cell.
After determining that 3G subscription is switched to 2G network from 3G network, 3G server can also determine the value W of the covering performance parameter that 3G network when network switches occurs according to the call bill data of the 3G network carried in the user's call data obtained, wherein, so-called covering performance parameter, preferably, can be PCCPCHRSCP(Primary Common Control Physical Channel Received Signal Code Power, Common Control Physical Channel received signal code power).
When step 110:3G server switches based on generation network, the value W of the covering performance parameter of 3G network generates the simulation covering performance parameter of the first number of samples, and according to the number of the adjacent 3G community of the target 2G cell at place after switching with 3G subscription and the first number of samples, determine the number of samples of the simulation covering performance parameter that the 3G community adjacent with above-mentioned target 2G cell is corresponding.
Be specially: 3G network server determines the call bill data of this 3G subscription at 2G network according to the identification information of user's calling parameter and 3G subscription current place 2G cell, and according to the duration of call T of this call bill data determination 3G subscription in target 2G cell, and the report cycle I of covering performance parameter of the 3G network preset is determined according to network configuration parameters, then, 3G server generates number of samples and is Z and value is the simulation covering performance parameter of W ', wherein, W '=W
namely Z is above-mentioned first number of samples, and also referred to as number of samples, by performing step 110,3G server generates the simulation covering performance parameter that Z value is W '.Such operation, object is the simulation covering performance parameter duration of call of 3G subscription in target 2G cell being converted to respective sample number according to the report cycle of covering performance parameter, carries out the use of 3G network coverage evaluating for follow-up.
Then, 3G server determines that the number of samples of the simulation covering performance parameter that each 3G community adjacent with above-mentioned target 2G cell is corresponding is Z ', wherein,
x is the number of the 3G community adjacent with above-mentioned target 2G cell; Namely each 3G community adjacent with above-mentioned 2G cell is all to there being Z ' individual simulation covering performance parameter.
Further, determine that 3G subscription is continued to switch to other target 2G cells by current place target 2G cell, then 3G server can adopt same way 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 the number of samples of the adjacent 3G community of other target 2G cells and the second number of samples, determine the number of samples (account form is identical with aforementioned manner) of the simulation covering performance parameter that the 3G community adjacent with other target 2G cells above-mentioned is corresponding; Wherein, if exist simultaneously with switch before and after the adjacent 3G community of target 2G cell, then 3G server can by each time to superposing by the 3G community number of samples that calculates the simulation covering performance parameter of acquisition.
The value that step 120:3G server is corresponding according to each 3G community is respectively the number of samples ratio of the covering performance parameter of W and the simulation covering performance parameter of calculating acquisition, assesses the coverage condition of corresponding 3G community.
For any one 3G community (hereinafter referred to as 3G community X), according to user's calling parameter, 3G server first determines that all values that corresponding 3G community X records are the number of samples z of the covering performance parameter of W, and determine that value that corresponding 3G community X records 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 is mated with the corresponding relation between default covering grade and ratio value, assess according to the network coverage status of matching result to 3G community X.
Below for covering performance parameter for PCCPCH RSCP, by a concrete application scenarios, further description is made to above-described embodiment, specifically as shown in Figure 2:
Step 200:3G server imports user call data (e.g., user is at the call bill data of 3G network and 2G network) and default network configuration parameters.
In the embodiment of the present invention, user's call data mainly comprise: calling takies the value of community, the duration of call, periodic measurement PCCPCH RSCP; Network configuration parameters mainly comprises the neighboring BS relationship of 2G cell and 3G community etc. information;
Step 201:3G server judges whether to there is the 3G subscription being switched to 2G network by 3G network according to the call bill data of the 3G network carried in the user's call data obtained, if so, then carry out step 202; Otherwise, carry out step 211.
3G server can judge whether according to the call bill data of 3G network the ticket that there is call interruption suddenly, when determining to there is this type of ticket, first can judge that the 3G subscription that this type of ticket is corresponding has been switched to 2G network, because, in the critical edges of 3G network and 2G network, if the signal of 2G network is better than 3G network, 3G subscription can be switched to 2G network voluntarily.
Such as: consult shown in Fig. 3, suppose that 3G subscription is at 3G community A, in moving process, can switch to 2G cell 1.
Step 202:3G server, for the 3G subscription that there occurs network switching, records the value W of the PCCPCH RSCP of 3G network when switching.
Step 203:3G server, according to the identification information of the target 2G cell after the user totem information of 3G subscription and switching, searches the call bill data of this 3G subscription in 2G network.
Namely 3G server is according to the LAC(location area code of target 2G cell, lane place), the user ID of cell ID (i.e. Cell ID) and 3G subscription (as, IMSI(International MobileSubscriber Identity, international mobile subscriber identification code) or TSMI(Temporary MobileSubscriber Identity, Temporary Mobile Subscriber Identity code)) and switching time point, search the call bill data produced after 3G subscription is switched to target 2G cell.
Does step 204:3G server judge whether to find the call bill data of 3G subscription at target 2G cell? if so, then carry out step 205; Otherwise, carry out step 211.
Step 205:3G server obtains the duration of call T of 3G subscription at this target 2G cell according to 3G subscription at the call bill data of 2G network.
Step 206:3G server is according to the report cycle I of PCCPCH RSCP in the 3G network of the duration of call T of 3G subscription in target 2G cell and configuration, the number of samples Z of calculating simulation PCCPCH RSCP.
value the W '=W of simulation PCCPCH RSCP.
According to network configuration parameters, step 207:3G server judges whether the target 2G cell at 3G subscription place exists adjacent 3G community; If so, then carry out step 208, otherwise, carry out step 210.
Such as, suppose that 3G subscription is current at 2G cell 1, then according to network configuration parameters, 3G server can determine that its adjacent 3G community is 3G community A and 3G community B; Or suppose that 3G subscription is at 2G cell 2, then 3G server determines its adjacent 3G community Jin You 3G community B according to network configuration parameters.
The number of samples X of the 3G community that step 208:3G server statistics is adjacent with target 2G cell.
The number of samples Z of step 209:3G server according to simulation PCCPCH RSCP and the number X of the 3G community adjacent with target 2G cell, calculates the number of samples Z ' of simulation PCCPCH RSCP corresponding to each 3G community.
Does step 210:3G server judge that 3G subscription switches to another target 2G cell from current target 2G cell? do you (namely judge that 3G subscription there occurs the switching in 2G network?) if so, then return step 203; Otherwise, carry out step 211.
According to the call bill data of 3G subscription, 3G server can judge whether 3G subscription there occurs the switching between 2G cell again, such as, 3G subscription is switched to 2G cell 2 from 2G cell 1, now, 2G cell 1 is adjacent with 3G community A and 3G community B, and 2G cell 2 is adjacent with 3G community B, visible, after the number of samples Z ' 1 calculating simulation PCCPCH RSCP corresponding to 3G community B based on 2G cell 1, also need the number of samples Z ' 2 calculating simulation PCCPCH RSCP corresponding to 3G community B based on 2G cell, and Dui 3G community B carry out the network coverage assessment time, want comprehensive reference above-mentioned number of samples Z ' 1 and Z ' 2.
The value that step 211:3G server is corresponding according to each 3G community is respectively the number of samples ratio of the PCCPCHRSCP of W and the simulation PCCPCH RSCP of calculating acquisition, assesses the network coverage status of corresponding 3G community.
Such as, suppose that value that 3G community C is corresponding be 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 community C obtains is 0, namely its number of samples ratio is 10:0, so, 3G server can determine that the network coverage status of 3G community C is for " excellent ".
Again such as, suppose that value that 3G community A is corresponding be 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 community A obtains is 5, namely its number of samples ratio is 10:5, so, 3G server can determine that the network coverage status of 3G community A is for " good ".And if not with reference to the number Z ' calculating the simulation PCCPCH RSCP obtained, then 3G server may determine that the network coverage status of 3G community A is for " excellent ", thus cannot know that 3G community A will occur the situation of overburden depth deficiency.
Again such as: suppose that value that 3G community B is corresponding be 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 community B obtains (Z ' 1+Z ' 2) be 9, namely its number of samples ratio is 10:9, so, 3G server can determine that the network coverage status of 3G community B is for " poor ".And if not with reference to the number (Z ' 1+Z ' 2) calculating the simulation PCCPCH RSCP obtained, then 3G server may determine that the network coverage status of 3G community B is for " excellent ", thus cannot know that the situation of overburden depth deficiency has appearred in 3G community B.
Other assessment modes all can be analogized with reference to aforesaid way, and this is no longer going to repeat them.
Certainly, the corresponding relation between the value of above-mentioned number of samples ratio and network coverage status can be summarized actual application environment and arrange flexibly, and above-mentioned record is only citing.
On the other hand, if directly go to step 211 process by step 202, be then considered as in the case the switching of 3G network to 2G network does not occur, so, when performing step 211, the number of samples of simulation PCCPCH RSCP corresponding for 3G community can be designated as 0 by 3G server;
And if directly go to step 211 process by step 204, then be considered as 3G subscription in the case and do not use business (namely target 2G cell can not disturb adjacent 3G community) at 2G network, so, when performing step 212, the number of samples of simulation PCCPCH RSCP corresponding for 3G community can be designated as 0 by 3G server.
Based on above-described embodiment, consult shown in Fig. 4, in the embodiment of the present invention, 3G server comprises determining unit 40, computing unit 41 and assessment unit 42, wherein,
Determining unit 40, when switching to the 3G subscription of 2G network for determining to exist according to the user's calling parameter obtained and the network configuration parameters of presetting by 3G network, determine the value W of the covering performance parameter that 3G network when network switches occurs according to described user's calling parameter;
