Fig. 1 is the flow chart of the method for the network node in control of the present invention network area.Wherein, method of the present invention is mainly carried out by control system, and described control system is to be arranged on application module in the network equipment etc.This network equipment be a kind of can be according to the program of prior storage, automatically, the modernization intelligent electronic device that carries out at high speed massive values computation and various information processings, its hardware includes but not limited to microprocessor, FPGA, DSP, embedded device etc.The described network equipment includes but not limited to: base station, eNodB etc.
In step S1, described control system is obtained the feature information network of the first network in the network area, and wherein, described feature information network comprises the network node information as bunch head.
Wherein, described first network comprises any network that can exist in the blind area mode, preferably, and the self-organizing network of described first network for existing in the blind area mode, for example, wireless sense network etc.The feature information network of described first network can adopt any form of presentation for expression information to represent, preferably, the feature information network of described first network adopts predefined function to represent.
For example, when only having one as the network node of bunch head in described first network, be used for representing that the predefined function of the feature information network of described first network is:
f charact＝f(BA charact，ID(CH i)，L(CH i)，S j) (1)
Again for example, when having when a plurality of as the network node of bunch head in described first network, be used for representing that the predefined function of the feature information network of described first network is:
F charact = F { BA charact , Σ i = 1 M ID ( CH i ) , Σ i = 1 M L ( CH i ) , Σ j = 1 N S j } - - - ( 2 )
Wherein, in above-mentioned formula (1) and (2), the implication of each parameter is as follows:
CH iIt is the index number of the network node of i conduct bunch head;
M is the number as the network node of bunch head;
BA CharactProperty parameters for first network;
ID (CH i) be i number information or address information as the network node of bunch head in first network;
L (CH i) be that first network is as i the geographical location information as the network node of bunch head;

Wherein, the described control system mode of obtaining the feature information network of the first network in the network area includes but not limited to: 1) network equipment by the feature information network of the described first network of storage offers described control system; 2) described control system generates or upgrades the feature information network etc. of described first network based on each network node information of the described first network of collecting voluntarily.For example, after each network node in the wireless sense network that exists in the blind area mode is waken up, described control system first based on this wireless sense network in gateway communicate by letter to gather the relevant information that comprises as the network node of bunch head, and then upgrade parameter in aforementioned formula (1) or (2), in order to obtain the feature information network of this wireless sense network.
In step S2, the communication equipment 2 that described control system sends to described feature information network in the second network that is in described network area and can adopt the communication protocol of described first network to communicate.
Wherein, described second network comprises any network that is different from first network and can merges with first network, preferably, includes but not limited to mobile cellular network, wireless broadband network etc.Described communication equipment 2 comprises the equipment that anyly can receive and send messages with the communication protocol of first network, also can receive and send messages with the communication protocol of second network, preferably, includes but not limited to dual-mode handset, bimodulus PDA etc.
For example, described control system belonging network equipment as the base station etc., sends the predefined function of blind area to described communication equipment 2.
Then, in step S3, described communication equipment 2 wake up based on described feature information network or the described first network of dormancy in as the network node 3 of bunch head, and then by network node 3 beginnings as bunch head wake up step by step or the described first network of dormancy in other network nodes.
For example, after described communication equipment 2 is received feature information network, after first the network equipment under the described control system is replied confirmation, then with maximum transmission power periodic broadcast Beacon signaling in order to wake the network node of conduct bunch head up; Subsequently, enter normal mode of operation by park mode after receiving the Beacon signaling as the network node of bunch head, and reply to communication equipment 2 and determine message; Then, the routing table information that backs up in advance according to self as the network node of bunch head sends and activates signaling to the sub-network node of its down hop, as shown in Figure 2, the sub-network node of down hop is entered normal mode of operation and is replied acknowledge message to his father's network node by park mode after receiving and activating signaling, subsequently, the routing table information that the sub-network node of down hop backs up in advance according to self again sends and activates signaling to the sub-network node of its down hop, wake so step by step network node up, until the network node of all terminals all is waken up.
Again for example, when described communication equipment 2 is wanted the deviated from network zone, if the network node as bunch head in first network changes, described communication equipment 2 send leave group message and as the relevant information of the network node of new bunch head to the network equipment under described control system, otherwise described communication equipment 2 directly sends its leave message signaling to the network equipment under described control system; Then, after described communication equipment 2 receives confirmation message from the network equipment under described control system, send sleep messages to the network node as bunch head, subsequently, network node as bunch head sends sleep messages to the all-ones subnet network node of its down hop, and enters park mode by normal mode of operation after the route stand-by table; Then, the sub-network node of down hop sends sleep messages to the all-ones subnet network node of its down hop, and enter park mode by normal mode of operation after the route stand-by table ... dormant network node so step by step is until the network node of all terminals is all by dormancy.
Need to prove, abovementioned steps S1 and S2 be also discontinuous execution in time, for example, after described control system is obtained the feature information network of the first network in the network area, it is not the operation of execution in step S2 immediately, but through after scheduled duration, described control system finds that the Monitoring Data of some blind area in network area that its belonging network equipment covers upgrades in this scheduled duration, the operation of described control system execution in step S2.
As a kind of optimal way, method of the present invention also comprises step S4 (not giving diagram).
