RESOURCE RESERVATION METHOD AND APPARATUS
First Claim
1. A resource reservation method, wherein the method is applied to a WiFi system, and the method comprises:
- receiving, by a destination node, a resource reservation request sent by a source node, and sending a resource reservation response to the source node, wherein the resource reservation response comprises a reservation time, and the resource reservation response is used to enable another node, which can monitor the resource reservation response, in the WiFi system to set a network allocation vector of the another node according to the reservation time; and
determining, by the destination node, whether data sent by the source node is received within a predetermined time; and
if the data is not received, sending a resource release instruction, so that the another node initializes the network allocation vector of the another node, and re-contends for a resource.

Abstract
A resource reservation method applied to a WiFi system includes: receiving, by a destination node, a resource reservation request sent by a source node, and sending a resource reservation response to the source node, where the resource reservation response includes a reservation time, and the resource reservation response is used to enable another node, which can monitor the resource reservation response, in the WiFi system to set a network allocation vector of the another node according to the reservation time; determining, by the destination node, whether data sent by the source node is received within a predetermined time; and if the data is not received, sending a resource release instruction, so that the another node initializes the network allocation vector of the another node, and re-contends for a resource, thereby solving a hidden node problem and also ensuring that a network resource is fully and properly used.

9. A resource reservation apparatus, wherein the apparatus is applied to a WiFi system, and the apparatus comprises:
-
a receiving unit, configured to receive a resource reservation request sent by a source node; a sending unit, configured to send a resource reservation response to the source node after the resource reservation request is received, wherein the resource reservation response comprises a reservation time, and the resource reservation response is used to enable another node, which can monitor the resource reservation response, in the WiFi system to set a network allocation vector of the another node according to the reservation time; a first determining unit, configured to determine whether data sent by the source node is received within a predetermined time; and a resource releasing unit, configured to, when the first determining unit determines that the data sent by the source node is not received, send a resource release instruction to the another node, so that the another node initializes the network allocation vector of the another node, and re-contends for a resource. - View Dependent Claims (10, 11, 12, 13)
