Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the specific embodiment of the invention is described in further detail.
For the defect of prior art, the embodiment of the present invention provides state method to set up, node and network, and the forwarding capability state of node can be set as required, thus save node energy consumption, reduce the interference to adjacent area.
The process of carrying out the setting of forwarding capability state to network side sending node ability information for node that following embodiment describes.The state method to set up signaling process figure that Fig. 3 provides for the embodiment of the present invention one.As shown in Figure 3, the method that the embodiment of the present invention provides comprises:
S301, node is to network side sending node ability information, and described node capacity information comprises whether described node supports forwarding capability.
S302, the node capacity information that network side receiving node sends.
S303, network side is described node configuration forwarding capability state information according to described node capacity information.
S304, network side is sent to described node by described forwarding capability state information, and for forwarding capability state described in described Node configuration, described forwarding capability state comprises opening, closed condition and resting state.
S305, node receives the forwarding capability state information for described node configuration that described network side sends.
S306, node arranges the forwarding capability state of described node according to described forwarding capability state information, and described forwarding capability state comprises opening, closed condition and resting state.
What above-described embodiment was described is, by node, to network side sending node ability information, carries out the setting of forwarding capability state, has realized the forwarding capability state that node can be set as required, thus save node energy consumption, reduce the interference to adjacent area.
Following embodiment describe for take the state method to set up flow process that node is main body, the state method to set up flow chart that Fig. 4 provides for the embodiment of the present invention two.As shown in Figure 4, described method comprises:
S401, node is to network side sending node ability information, and described node capacity information comprises whether described node supports forwarding capability.
Particularly, during initial network entry, new node can report to network side the node capacity information of oneself, this information to comprise whether supporting forwarding capability; Or, when node is when working, if forwarding module breaks down, or possess forwarding capability after node device upgrading, node is initiatively to network side sending node ability information.
S402, described node receives the forwarding capability state information for described node configuration that described network side sends.
Node is sent to node capacity information after network side, and network side can for Node configuration forwarding capability state, and be sent to node by this information as required for node configuration forwarding capability state information, and node receives this information.
Particularly, have the access of new node or network side need dilatation or currently have node to report link failure if current, need to readjust topology, now to configure all or part of node be opening to network side;
If current network does not have new node access demand or band resource limited, now network side decision node is configured to closed condition;
If current in the networking initial stage, the possibility that has new node to add is larger, in order to support fast new node, and saves electric energy, and now network side configuration node is resting state.
S403, described node arranges the forwarding capability state of described node according to described forwarding capability state information, and described forwarding capability state comprises opening, closed condition and resting state.
Wherein, opening refers to that the forwarding module of node normally works, and comprises and sends broadcast channel, synchronizing channel, pilot tone and Random Access Channel.Closed condition refers to that the forwarding module of node does not send downstream signal and do not receive upward signal yet, and network side do not have the context of node forwarding capability, the frequency, bandwidth, community ID, the network interface (X2, S1 interface etc.) that use such as forwarding capability.When node need to start forwarding capability, must configure the context of forwarding capability.The identical point of resting state and closed condition is, the forwarding module of node does not send all downstream signals, but network side has the context of node forwarding capability, when node need to start forwarding capability, do not need to reconfigure the context of forwarding capability, node can start forwarding capability at once.
Therefore, if the described forwarding capability state of described node is set to opening, described node can send downstream signal, or receives upward signal; If described node forwarding capability state is set to closed condition, stop sending downstream signal, and the contextual information of the forwarding capability module BRN of deletion of node; If the described forwarding capability state of node is set to resting state, stop sending downstream signal.
Alternatively, described method also comprises: the described forwarding capability state that described node completes setting is sent to described network side.
