A cell handover method suitable for td-lte public network trunking system

Abstract

The invention discloses a method for cell switchover suitable for a TD-LTE public network trunking system. The method for cell switchover suitable for the TD-LTE public network trunking system comprises the steps that when a group composed of a plurality of mobile radio stations conducts cross-cell switchover, a temporary small network is constituted by the mobile radio stations needing switchover according to a preset threshold; a bridge group user is selected from the small network, wherein two sets of transceivers are assembled to the bridge group user so that communication can be conducted on networks at two different frequencies at the same time; information sent by a source base station is transmitted to other group users in the temporary small network by the bridge group user. Switchover from the source access station to a target access station is achieved through the bridge group user and after the bridge group user enters a target network, the other group users sequentially enter the target access station through negotiation between the bridge group user and the target access station. According to the scheme, collision in the process of switchover of the group is remarkably reduced, so that time of interruption of services of the mobile radio stations is reduced, and the mobile radio stations are compatible with an existing wireless network.

Description

Technical field [0001] The present invention relates to the field of wireless communication, in particular to a cell handover method of a TD-LTE public network trunking system. Background technique [0002] With the development of the fourth-generation mobile communication network, the trunking communication system will also evolve to the fourth-generation trunking communication system. The traditional trunking communication system is mainly dedicated to meet the business nature and use environment of different industry sectors. Requirements, formed a variety of different cluster communication systems. However, for general enterprises, logistics, transportation and other departments, these industry departments have relatively low requirements for cluster networks, and they mainly reflect economic benefits. Therefore, these departments generally adopt a shared trunking communication system that shares frequency resources and network infrastructure, or use a public mobile communic...

Problems solved by technology

[0006] In the current patent, there is no switching method for simultaneous switching of a large number of group users in the public network cluster system, but all the information of the group users is sent from the source base station to the target base station together, but in the actual situation, not all group users Group users will switch, and the appropriate switching of group users and the user's parameter information at that time cannot be determined
