All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Examples
The embodiment provides a method applied to time slot resource multiplexing of a TDMA data chain, which comprises the following steps:
as shown in fig. 1, in the TDMA data chain, data transmissions of different traffic types share link-level radio resources that have been allocated, and then a scheduler performs scheduling according to priorities of the traffic types;
when the new service type needs data transmission, a forwarding path is acquired through a routing table, and link-level wireless resources are allocated by judging whether the link-level wireless resources on the forwarding path meet the data transmission requirement of the new service type. Wherein:
when the link-level wireless resource on the forwarding path meets the data transmission requirement of the newly added service type, the new link-level wireless resource is not required to be allocated;
when the link-level wireless resource on the forwarding path does not meet the data transmission requirement of the newly added service type, the new link-level wireless resource needs to be allocated.
Therefore, the wireless resource allocation times are reduced, the complexity of wireless resource management is reduced, and the utilization rate of the link wireless resources is improved.
Specifically: the method for judging whether the link-level wireless resource on the forwarding path meets the data transmission requirement of the newly added service type comprises the following steps:
acquiring the allocated wireless resource on the link;
acquiring a wireless resource actualrounce actually occupied by current data transmission on a link;
acquiring wireless resource demandResource required by newly added service types on a link;
configuring a wireless resource threshold value X% when a link is idle;
judging whether the current link can be multiplexed according to the expression (allocResource-actualResource) > demandResource: if the expression is established, the data transmission of the newly added service type does not need to be carried out without distributing new link-level wireless resources, and if the expression is not established, the data transmission of the newly added service type needs to be carried out by distributing new link-level wireless resources.
Examples:
a data transmission schematic of the traffic type as shown in fig. 2. Wherein:
node1 has the data transmission requirement that the service type is 1 and the destination is Node3, and obtains the forwarding path as Node1- > Node2- > Node3 after routing through the routing table. Allocating wireless resources for links between nodes on the forwarding path;
the Node4 has the data transmission requirement of the service type 2 and the destination Node3, and obtains the forwarding path of Node4- > Node2- > Node3 after routing through the routing table. And allocating wireless resources for the links between the nodes node4 and node2, judging whether the link-level wireless resources between the nodes node2 and node3 can meet the data transmission requirement of the service type 2, and if so, not needing to be allocated.
The implementation flow is as shown in fig. 3, and existing service data is being transmitted between the nodes node1 and node 2:
the node1 has the data transmission requirement of the newly added service type, and the data needs to be transmitted to the node2;
acquiring wireless resource information of data transmission requirements of the newly added service type;
acquiring current link-level wireless resource information;
and judging whether the newly added wireless resources are needed to meet the data transmission of the newly added service types according to the rule of wireless resource multiplexing.
If the radio resources satisfy the multiplexing, the data can be directly transmitted to the node2 without newly allocating the resources. If the resources cannot meet multiplexing, new wireless resources are needed, and after the new wireless resources are updated to the node2, data transmission can be performed.
