Transmitting handover method, related equipment and communication system

Abstract

The invention discloses a transmitting handover method, related equipment and a communication system. When the method is applied to a base station, the base station receives a target base station service channel request instruction, and the service channel request instruction is an instruction that a transmitting terminal embeds base station request information in a voice super frame under a specific condition; the service channel request instruction is processed to obtain service channel information of the target base station; and the target base station service channel information is fed back to the transmitting terminal in a target mode, so that the transmitting terminal switches the voice transmitting service to the target base station service channel, and the target mode represents amode of continuously issuing a plurality of reverse information. The service channel of the pre-switching station is issued by adopting the reverse information packet format, so that continuous transmitting and seamless switching of the terminal are realized, and the purposes of ensuring the continuity of the voice of a transmitter in the non-participated station transmitting handover process of the terminal, ensuring that the voice of a receiver does not drop words and improving the user experience are achieved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a transmission handover method, related equipment and a communication system. Background technique [0002] DMR (Digital Mobile Radio) digital trunking communication standard is an open standard designed and formulated by ETSI (European Telecommunications Standards Institute) to meet the mobile communication needs of low-end professional and commercial users in European countries. In DMR digital trunking communication, voice service is the most important and frequently used function, and users expect high voice service quality under any circumstances. [0003] In the process of using the terminal, it is unavoidable to perform inter-cell handover during voice. For the cell switching process during voice transmission, the existing methods all have the problem of voice drop and discontinuity, which may lose key voice information, affect user judgment and decision-making, and ...

AI Technical Summary

Problems solved by technology

For the cell switching process during voice transmission, the existing methods all have the problem of voice drop and discontinuity, which may lose key voice information, affect user judgment and decision-making, and cause accidents and heavy losses in emergency situations.

[0004] In order to solve the above problems, the existing solutions all have a process in which the terminal changes from the voice transmission state to the signaling reception state, and retransmits the voice header and encrypted header information. This process leads to discontinuous voice transmission, word drop, and affects user experience.
