Problems solved by technology

[0013] The technical problem to be solved by the present invention is to provide a switching method between an optical channel and a radio channel to overcome the long switching discovery time in the existing switching method in the prior art, the switching time cannot meet the requirements of real-time multimedia transmission, and shorten the switching time. These disadvantages caused by the time delay lead to excessive use of network capacity stations

Embodiment Construction

[0066] The method of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0067] The core idea of ​​the present invention is: when the optical interface is interrupted due to occlusion or movement of the mobile station, quickly switch the data carried by the optical interface to the radio interface, wait until the optical interface returns to normal, and then transfer the data that needs to be carried by the optical interface Switch back from the wireless interface. Comprehensive allocation of resources is performed between the optical interface and the radio interface according to the transmission code rate required by the quality of service. The present invention also uses the high-level wireless interface to protect the low-level optical interface, so that the unreliable optical interface can transmit real-time multimedia services guaranteed by QOS (Quality of Service), widen the application range of...

Abstract

A method for realizing switch ¿C over between optical channel and radio channel includes setting up correlation of radio channel and optical channel between setting up terminal and switching in point, judging whether optical channel is blocked or not, sending switch over data of optical channel to radio channel, executing switch over of optical channel to radio channel, carrying out detection on switch over of radio channel to optical channel, sending switch over data of radio channel to optical channel and executing switch over of radio channel to optical channel.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a vertical switching method between an optical interface at a lower layer and a wireless interface at an upper layer in the field of wireless communication. Background technique [0002] With the increasing popularity of wireless communication and the increasing demand for bandwidth, the radio (RADIO) spectrum is becoming increasingly tight, and new technical means need to be sought to solve the shortage of radio spectrum. Although the optical (OPTICAL) spectrum has the characteristics of fast transmission speed, no RADIO interference and simple implementation in specific environments (such as in-car and indoor), but the optical channel is easily blocked and the coverage is small, so the optical channel cannot guarantee The reliability of mobile terminal communication. How to use optical (OPTICAL) channel and radio (RADIO) channel comprehensively to construct a reliable air...
