A resource allocation method and device

Abstract

The embodiment of the invention provides a resource allocation method and device. The method is applied to a satellite communication system, the satellite communication system comprises a satellite device and a terminal device, the satellite device receives a radio resource control (RRC) connection establishment request message sent by the terminal device, and the request message comprises a signaling resource occupation demand between the terminal device and the satellite device; judging whether a special control carrier meeting the resource occupation requirement of the signaling exists or not for the first time; if yes, searching a target carrier from special control carriers meeting the resource occupation requirement of the signaling; If not, searching a target carrier from the voiceservice carriers; and allocating resources for the signaling in the target carrier wave, generating resource allocation information, generating an RRC connection establishment message according to theresource allocation information, and sending the RRC connection establishment message to the terminal device. According to the embodiment of the invention, by adding the carrier capable of bearing the signaling, the success rate of terminal equipment access is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a resource allocation method and a resource allocation device. Background technique [0002] The satellite communication system is composed of satellite equipment, ground stations and terminal equipment corresponding to users. Since the satellite equipment works on orbits of hundreds, thousands, or even tens of thousands of kilometers, the coverage of the satellite communication system is much larger than that of the general mobile communication system. , so the satellite communication system can be used to achieve large-scale coverage; among them, signaling, business data, etc. are transmitted between the terminal equipment and the satellite equipment in the satellite communication system with the carrier as the carrier. [0003] The resource allocation method in the satellite communication system is to allocate resources for signaling only on the dedicated cont...

AI Technical Summary

Problems solved by technology

[0003] The resource allocation method in the satellite communication system is to allocate resources for signaling only on the dedicated control carrier, but the number of dedicated control carriers and the resources on each carrier in the satellite communication system are limited. When the number of users is large, Access failures often occur, which affects the user's access success rate
