Abstract
Embodiments of the present invention provide a resource allocation method and apparatus. A central control node determines a target backhaul node for a normal small cell from M candidate backhaul nodes and communication link resource information between the normal small cell and the target backhaul node based on access link resource pre-occupation information of the normal small cell, link quality information between the normal small cell and each of the M candidate backhaul nodes, and available backhaul link resource information sent by the M candidate backhaul nodes.
Claims18
A resource allocation method, comprising:
- receiving, by a central control node, a first message sent by a first cell, wherein the first message comprises access link resource pre-occupation information regarding resource occupation on an access link to the first cell;
- receiving, by the central control node, a second message sent by the first cell, wherein the second message comprises link quality information between the first cell and each of M candidate backhaul nodes, and M is an integer greater than or equal to 2;
- receiving, by the central control node, available backhaul link resource information sent by the M candidate backhaul nodes;
- determining, from the M candidate backhaul nodes, by the central control node, a target backhaul node for the first cell and communication link resource information between the first cell and the target backhaul node based on the access link resource pre-occupation information, the link quality information between the first cell and each of the M candidate backhaul nodes, and the available backhaul link resource information sent by the M candidate backhaul nodes;
- sending, by the central control node, a third message to the first cell, wherein the third message comprises an identifier of the target backhaul node and the communication link resource information between the first cell and the target backhaul node;
- wherein determining, from the M candidate backhaul nodes, by the central control node, the target backhaul node for the first cell based on the access link resource pre-occupation information;
- the link quality information between the first cell and each of the M candidate backhaul nodes, and the available backhaul link resource information sent by the M candidate backhaul nodes comprises:
- calculating, by the central control node, based on the access link resource pre-occupation information, the link quality information between the first cell and each of the M candidate backhaul nodes, and the available backhaul link resource information sent by the M candidate backhaul nodes, a corresponding throughput sum of all subscribers served by the first cell for each candidate backhaul node, to obtain M throughput sums;
- and
- determining, by the central control node, a candidate backhaul node corresponding to a maximum throughput sum in the M throughput sums as the target backhaul node.
