Fig. 2 is referred to, shows wireless transmission resources collocation method in a kind of wireless Mesh netword of the embodiment of the present invention Flow chart, this method are applied to the main Mesh nodes in the wireless Mesh netword shown in Fig. 1.As shown in Fig. 2 this method include with Lower step：

S110, main Mesh nodes obtain the network configuration information of current wireless Mesh netword.

The node number that network configuration information includes the traffic type information that is carried of whole network, network can accommodate. After wireless Mesh netword is built, its traffic type information carried and the number of nodes that can be accommodated have been configured.

For example, traffic type information can include：Based on delay sensitive business, supplemented by burst service；With burst service Based on, supplemented by delay sensitive business；Delay sensitive business and burst service are taken into account.

S120, main Mesh nodes include the money of subframe according to network configuration information, one wireless transmission resources frame of configuration The quantity of subframe corresponding to Source Type and every kind of resource type.

Generally, after a wireless Mesh netword structure is completed, network configuration information has configured completion, according to network Resource type that each wireless transmission resources frame that configuration information can configure current wireless Mesh netword is included and every kind of The quantity of subframe corresponding to resource type；In other words, after the completion of a wireless Mesh netword structure, the wireless biography of the Mesh network Sub-frame number corresponding to the resource type and every kind of resource type that defeated resource frame is included has been fixed.Different is wirelessly transferred money In source frame, the Mesh nodes that scheduling resource is distributed may be different.

The resource type of wireless transmission resources frame includes static allocation resource and dynamic dispatching resource.Static allocation resource is led to Normal pre-configured resource is used by which Mesh node, and the necessary signaling message and delay sensitive of network are maintained for transmitting Business；Dynamic dispatching resource can distribute to different Mesh nodes in the different periods, be generally used for transmitting burst service, example Such as, when some node has transmission burst service demand, for the node distribution dynamic dispatching resource.

In a kind of possible implementation of the application, in wireless Mesh netword, what a wireless transmission resources frame included Subframe is Transmission Time Interval (Transmission Time Interval, TTI), i.e. a subframe is a TTI.Main Mesh Node can determine that each wireless transmission resources frame is included according to the number of nodes that whole wireless Mesh netword can accommodate TTI resource quantities.

The number of nodes that wireless Mesh netword is accommodated is more, the TTI number of resources that a wireless transmission resources frame is included Amount is also more.But the TTI resource quantities that a wireless transmission resources frame includes are more, whole wireless Mesh netword renewal The speed of critical system message can be slower.

Then, main Mesh nodes can determine a wireless transmission resources according to the type of service of current wireless Mesh netword Frame includes the resource type of subframe.

For example, the type of service of current wireless Mesh netword is based on delay sensitive business, supplemented by burst service, then one Individual wireless transmission resources frame includes static allocation resource and dynamic dispatching resource simultaneously, and based on static allocation resource；And for example, Current wireless Mesh netword is based on burst service, supplemented by delay sensitive business, then a wireless transmission resources frame includes simultaneously Static allocation resource and dynamic dispatching resource, and based on dynamic dispatching resource.
