A method, device and system for realizing resource reservation

Abstract

The invention discloses a method, a device and a system for realizing resource reservation. The method comprises the following steps: when equipment needs to transmit a data service, judging whether the data service is a real-time service; if so, using a row reservation mode, and if not, using a column reservation mode or asynchronous mode; and when using the row reservation mode, calculating thenumber of the correspondingly reserved media access slots (MAS) and the position of the media access slots (MAS) in the whole MAS matrix according to the requirements of different data services on theservice quality and the service volumes, so as to select the matching row reservation mode to transmit the data service. The embodiment can optimize the distribution of slot resources, can not causewaste of resources due to no data transmitted in the reserved MAS, and enhances the success ratio of the MAS reservation and the utilization rate of the system resources.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method, apparatus and system for realizing resource reservation. Background technique [0002] The existing ultra wideband (UWB, ultra wideband), as a new generation wireless communication technology, is one of the key technologies for realizing high-speed wireless personal area network (WPAN, wireless personal area network) multimedia transmission. UWB can provide wireless connectivity solutions for consumer electronic devices, enabling them to run on a common radio frequency platform to achieve high-speed, interoperable wireless multimedia communications. In the UWB system, there may be multiple wireless devices accessing the channel at the same time, resulting in conflict with each other. At the same time, because the UWB system has the characteristics of occupied frequency bandwidth, high transmission rate and very low transmit power spectral density,...

Problems solved by technology

[0009] In the process of implementing the present invention, the inventor found that the prior art has at least the following disadvantages: the MAS reservation scheme of the ECMA-368 standard is adopted, in which the row reservation adopts the method of whole row reservation, which may cause time resources Wasteful, because the device can only reserve the entire line. Taking the transmission rate of 200Mbps as an example, the traffic that can be transmitted in each line can reach about 800kb

For services with small traffic volume and sensitive delay, it is not necessary to fully occupy the reserved MAS time, so the reserved MAS is not fully utilized. Therefore, when resources are in short supply due to increased network load, This way of reserving the entire line will inevitably cause waste of system resources, resulting in a decrease in network throughput
