Fig. 1 shows the realization flow of dead zone of cell removing method of the present invention, and as shown in Figure 1, described method comprises the steps:
Step 101, network management system is the network element establishment monitoring model managed and stores;
Specifically, in this step, at least one network element managed for network management system creates monitoring model; Wherein, described monitoring model can comprise network element utilization ratio, dead zone of cell scope and adjacent area network element monitoring model three attribute; Network element utilization ratio can be determined by calculating telephone traffic, and dead zone of cell scope can be determined by calculating Diao Hua district, community scope, and adjacent area network element monitoring model can be some, and each adjacent area network element monitoring model includes above-mentioned three attribute simultaneously.
Step 102, when finding the network element that there is dead zone of cell, obtains the adjacent area network element monitoring model of the monitoring model of described network element;
Specifically, both can have been there is the network element of dead zone of cell by existing scientific discovery about the network element how finding to exist dead zone of cell, can also by analyzing the monitoring model of network element, obtain the network element that there is dead zone of cell, when realizing for the latter, it is specially the dead zone of cell range data that network management system analyzes the monitoring model of described network element, when the dead zone of cell of the monitoring model of a certain network element is greater than default first threshold value, described network element is monitored as key monitoring object; When the dead zone of cell scope of the monitoring model monitoring the network element as key monitoring object further is greater than default Second Threshold, it is determined that described network element exists dead zone of cell, obtains the adjacent area network element monitoring model of the monitoring model of this network element.
Step 103, according to described adjacent area network element monitoring model, using adjacent area network element low for the network element utilization ratio of adjacent area network element monitoring model as network element for subsequent use, and strengthens the transmitted power of described network element for subsequent use;
Before this step, described method also comprises: the adjacent area network element corresponding with described adjacent area network element monitoring model according to the default cycle is mutual, upgrade the network element utilization ratio of the monitoring model of described adjacent area network element, dead zone of cell scope and adjacent area network element monitoring model, with the validity of the relevant data that ensure the monitoring model of adjacent area network element, the cycle of renewal can be set usually, as one week upgrades once.
In this step, according to the quantity of dead zone of cell scope and adjacent area network element, according to the network element utilization ratio order from low to high of adjacent area network element monitoring model, it is determined that network element for subsequent use; Specifically, obtain the network element utilization ratio attribute of each adjacent area network element from adjacent area network element monitoring model, and sort according to height, select adjacent area network element from low to high, when selected adjacent area network element transmitted power sum can blind area, coverage cell, using selected adjacent area network element as network element for subsequent use; Here, the quantity of network element for subsequent use is determined jointly according to the quantity of the dead zone of cell scope of fault network element and adjacent area network element.
Here, the transmitted power of the described network element for subsequent use of described enhancing is specially: determines the power enhancing degree of network element for subsequent use according to the network element utilization ratio of the quantity of dead zone of cell scope, network element for subsequent use and network element for subsequent use and strengthens.
In addition, present method also comprises: when the network element that there is dead zone of cell recover normal after, reduce the transmitted power of described network element for subsequent use, cancel the monitoring of described fault network element as key monitoring object.
Fig. 2 shows the realization flow of the specific embodiment of dead zone of cell removing method of the present invention, as shown in Figure 2, the occurrence scene of described specific embodiment is at Telecommunications Management Network (TelecomManagementNetwork, TMN) wireless network control device (RadioNetworkController, RNC) in network management system, when network element power-off, there is serious alarm in network management system, and network management system detects that blind area situation occurs in community; Detailed implementation step is as follows:
Step 201, network management system is that all network elements managed create monitoring model;
Here, described monitoring model comprises network element utilization ratio, dead zone of cell scope, adjacent area network element monitoring model three attribute. Wherein, network element utilization ratio can be determined by calculating telephone traffic; Dead zone of cell scope can Diao Hua district, general-purpose computations community scope be determined, adjacent area monitoring model comprises the monitoring model of some adjacent areas, and the monitoring model of each adjacent area comprises above-mentioned three attribute.
Specifically, dead zone of cell scope can represent with Area; This value can reflect the scope of blind area, current area, thus can calculate the coverage power that it needs, and concrete calculation formula can be labeled as W=k* (Area), and k is weighting, the coverage power that k=Wmax/Sarea representation unit area needs. Wherein, Wmax is the power of network element under normal communication state; Sarea is the cell coverage area of network element. In addition, in addition it is also necessary in advance to blind area design two threshold values: the first threshold value, represents with variable BlindArea1; Second Threshold, represents with variable BlindArea2.
Network element utilization ratio can represent with Rate; This value can reflect the call scenarios of network element, and Rate is more little, represents that the call of network element is more few, otherwise, then more big; Can effectively be judged by this value, the network element for subsequent use that whether can act on other adjacent area network elements of current network. Wherein, so-called network element for subsequent use here is relative concept, is for subsequent use, and really is for subsequent use relative to other network elements.
Above-mentioned monitoring model also can relate to the quantity of adjacent area, it is possible to obtain the value of this variable by calculating the quantity of the adjacent area monitoring model of the monitoring model of network element. Can represent with Number; By obtaining this value, it is possible to learn the situation around fault network element, Number is more big, represents that the adjacent area network element device that can utilize is more many, and alternative is more big, keeps the probability of network element stabilized communication more big; Otherwise the network element device for subsequent use that can utilize is more few, and alternative is more few, keep the probability of network element stabilized communication more little.
Step 202, network management system stores the monitoring model of each network element, analyzes the dead zone of cell range data of each monitoring model;
Specifically, when the dead zone of cell scope of monitoring model of a certain network element is more than the first threshold value BlindArea1, webmaster includes this network element in key monitoring object, the dead zone of cell scope being used as the monitoring model of the network element of monitored object of attaching most importance to exceedes default Second Threshold BlindArea2, and webmaster will obtain and resolves the monitoring model that this network element is corresponding.
Here, this step can also comprise: when monitoring model corresponding to this network element of network management system by obtaining, adjacent area network element monitoring model can be obtained from database, then by mutual with adjacent area network element, upgrade the data such as the dead zone of cell scope of the reported by network elements corresponding to the network element monitoring model of described adjacent area, network element utilization ratio, adjacent area network element monitoring model, can effectively ensure the up-to-date property of all attributes of the monitoring model of current network like this.
Step 203, takes out the attribute of network element utilization ratio from the monitoring model of adjacent area network element, and sorts according to height, selects the adjacent area network element currently with lower network element utilization ratio as network element for subsequent use;
Specifically, in this step, the number of the adjacent area Network element object of the lower network element utilization ratio selected needs jointly to determine according to the dead zone of cell scope of fault network element and the quantity of adjacent area network element. Its account form is as follows: when fault network element (network element of dead zone of cell occur) has four adjacent area network elements, the transmitted power of each network element is respectively W1, W2, W3, W4, network element utilization ratio is followed successively by Rate1, Rate2, Rate3, Rate4, and the dead zone of cell scope of fault network element obtains its transmitted power W=k* (Area) needed; As W1 > W, then with network element corresponding to W1 as network element for subsequent use, otherwise calculate W1+W2, if W1+W2 is > W, then with network element corresponding to W1, W2 as network element for subsequent use, until network element transmitted power for subsequent use and the power W that is greater than fault network element needs; If the idle power sum of all adjacent areas network element is not greater than W, then whole adjacent areas network element is needed to carry out the power that best endeavors undertake fault network element needs.
Step 204, network management system receives the network element for subsequent use determined, analyzes network element attribute for subsequent use, and calculating each network element for subsequent use is cover the transmitted power that should strengthen when the blind area of prior fault network element;
Specifically, in this step, each network element for subsequent use needs the transmitted power account form strengthened as follows: obtain its transmitted power needed according to the blind area scope of fault network element, W=k* (Area); The network element utilization ratio Rate of the monitoring model according to network element for subsequent use can calculate its power proportions that can undertake fault network element. Such as when fault network element has four adjacent network elements, network element utilization ratio is followed successively by Rate1, Rate2, Rate3, Rate4, is selected the network element for subsequent use of Rate1, Rate2, Rate3 tri-fault network element power as a supplement by step 203. It undertakes the power ratio of enhancing successively: (1-Rate1): (1-Rate2): (1-Rate3), and the enhancing power undertaken successively is: W (1-Rate1), W (1-Rate2), W (1-Rate3).
Step 205, network management system, by, after the calculating of step 204, carrying out issuing message, notifies the size of power that selected network element for subsequent use strengthens its transmitted power and to be strengthened, it is achieved automatically regulate the function of fault network element adjacent network elements power.
Step 206, after automatically regulating, communication system recovers normal.
, it is also possible to manually utilize the attribute of each module of webmaster, here the fault of analyzing and positioning current network, orients reason, deals with problems.After fault network element recovers normal communication, described fault network element can report message recovery to network management system automatically.
Step 207, the recovery that network management system receives fault reported by network elements is normally after upper row (UpMessage) message, issue descending (DownMessage) message to network element for subsequent use, reduce the transmitted power of network element for subsequent use, before returning to, release network element for subsequent use to the covering in described fault network element region.
Step 208, network management system cancels the key monitoring to fault network element, makes the dead zone of cell scope of the monitoring model of current network leave Second Threshold, enters normal region.
There is the embodiment of dead zone of cell in the present invention under can also providing other scenes, be specifically as follows by dynamic data management module, it has been found that community is in blocked state, and blind area state occurs in community; Managing module by alarm, it has been found that community occurs moving back the problem of clothes, there is blind area state etc. in community.
