Embodiment 1

[0102] Embodiment 1 of the present invention provides an information transmission method for the base station in the LTE1800 trunking system to perform an ftp upgrade to the user terminal, to describe the specific implementation process of the embodiment of the present invention in detail, see Figure 6 :

[0103] Step 601: transmission preparation for ftp upgrade.

[0104] In this stage, each user terminal that needs to be upgraded or information transmitted is mainly notified through a suitable method. The content to be transmitted includes: specific upgrade method, upgrade file information verification information, version number, etc. If the user terminal and the base station already have a default agreement, this step can be omitted. A typical implementation is as follows: obtain the UE terminal ID and IP that need to be multicast upgraded; send the information required for the upgrade to the UE terminal, including the name of the upgrade file, version number, IP addres...

Embodiment 2

[0114] Embodiment 2 of the present invention provides an information transmission method for user terminal ftp upgrade in the LTE1800 trunking system, see Figure 7 ,include:

[0115] Step 701: Receive the data content of the information to be delivered sent by the base station in the form of carousel through the concurrent channel.

[0116] In this step, the user terminal not only receives the ftp upgrade file information broadcast by the base station, but also receives the extended frame number and current extended frame number information of the initial file block sent by the base station, so as to obtain the real-time extended frame number, and deduce The sequence number of the file block.

[0117] In addition, the user terminal will also timely confirm whether the file block is received correctly by receiving the file block self-verification information sent by the base station, which greatly reduces the interaction time between the user terminal and the base station due...

Abstract

The invention provides an information transmission method and an information transmission device for an eNodeB and user equipment. The eNodeB information transmission method comprises the steps of: sending data content of information to be transmitted in a carousel form through concurrence information channels; and completing the information transmission through a subsequent information transmission method judged by the user equipment according to receiving time expectation of unreceived part when the transmitted data content reaches a set threshold value. The invention provides the enhancement type multicast information transmission method and the enhancement type multicast information transmission device for a large amount of user equipment, the enhancement type multicast information transmission method comprises a wireless remote information transmission method and a new multicast transmission method, ensures the efficiency and reliability of information transmission, and eliminates the connectionless feature of traditional multicast. The information transmission method and the information transmission device effectively ensure the information transmission efficiency between the eNodeB and the user equipment based on the strategy of shortest overall expectation time.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for transmitting information between a base station and a user terminal. Background technique [0002] LTE1800 trunking system is a dedicated command and dispatch mobile communication system based on TD-LTE technology. It works at 1800MHz. Its feature is that all available channels in the system are shared by all users, and it has the function of automatic channel selection. It is a wireless communication system with shared resources, shared costs, shared channel equipment, multi-purpose services and high-efficiency command and dispatch functions. Since the trunking system mainly focuses on command and dispatch communication, its application requirements can cover transportation, public safety, special communication, enterprise production process and other fields, and it can especially play its advantages in responding to emergencies and natural...
