Embodiment Construction

[0024] In order to provide an implementation plan for improving the utilization rate of the time-frequency resources occupied by the base stations of the high-speed railway private network, the embodiment of the present invention provides a method and device for allocating time-frequency resources of the high-speed railway private network. The preferred embodiments are described, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention. And in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0025] An embodiment of the present invention provides a time-frequency resource allocation method for a high-speed railway private network, such as figure 1 shown, including:

[0026] Step S101, determining the designated area that the train will pass through and the ti...

Abstract

The invention discloses a time frequency resource allocation method and device of a high speed railway special network. The method comprises that an assigned region that a train is going to pass and a time period that the train passes the assigned region are conformed; a time frequency resource occupied by a public network base station to which the assigned region is attributed is conformed; and during the time period, an assigned time frequency resource is withdrawn from the time frequency resource occupied by the public network base station, and the withdrawn assigned time frequency resource is allocated to the high speed railway special network base station to which the assigned region is attributed. With the help of the scheme provided by the embodiment of the invention, a use efficiency of the time frequency resource occupied by the high speed railway special network base station is enhanced.

Description

technical field [0001] The present invention relates to the technical field of high-speed railway private network in the technical field of mobile communication, in particular to a time-frequency resource allocation method and device for high-speed railway private network. Background technique [0002] In the scenario where mobile communication networks, such as LTE (Long Term Evolution, Long Term Evolution) networks are used to provide broadband wireless access for mobile devices on trains traveling on high-speed railways, in order to ensure service quality, construction of high-speed railway private networks can be adopted scheme. This makes the public network and high-speed railway private network coexist in the area along the high-speed railway. In order to avoid mutual interference between the public network and the high-speed railway private network, different operating frequencies can be configured for the high-speed railway private network base stations and public n...
