Description

A Handheld Terminal with Base Station Relay Function

technical field

The present invention relates to the field of communication technology, in particular to a hand-held terminal with a base station relay function. the

Background technique

In modern communication, the typical network communication is the most common, and also includes mail, telephone, fax, satellite phone, telegram and so on. Each communication method has its own advantages and disadvantages, as well as its rationale for existence. the

Usually our telephone communication uses the terminal to transmit the signal to the base station, and then the base station transmits it to the range of the base station where the receiving terminal is located, and then the base station transmits the signal to the receiving terminal. In this case, the communication will be affected by the number of visits to the base station at that time, the density and distance of the base station, and there are certain disadvantages for small-scale, localized communication with high frequency, high individual mobility, and far away from the base station. Therefore, for regionally strong communications, communications can be carried out independently without using the base station of the communications operator. It is a mobile terminal with integrated communication and relay functions, especially in special places such as mining areas, tunnels and even battlefields, where communication independence and information forwarding are required. the

However, our group communication usually does not have the functions of priority and data forwarding, nor does it have confidentiality for communication information. the

Contents of the invention

The purpose of the present invention is to provide a handheld terminal with a base station relay function. The terminal itself has relay, receiving and sending functions, and identification functions. The relay function is integrated into the handheld computer, which is also a hand-held mobile base station, and a hand-held mobile terminal with telephone communication function and data processing function. It can communicate with different priority terminals separately, so that it can Ensure the confidentiality of information in communication; provide fast data processing and forwarding for communication between multiple terminal devices. the

Including the handheld computer, it also includes the local communication part and the relay communication part, the local communication part and the relay communication part are integrated in the handheld computer; 

The local communication part uses the signal transmitting part to send the signal to be transmitted to the transmitter through additional identity and address information; the signal receiving part will share the receiver with the relay part, and then identify the signal to determine that it is a local signal , into the processor, and then voice output;

In the relay communication part, after the receiver receives the signal, it identifies it, and after it is determined that the signal is not received locally, it processes it, filters out the noise and strengthens it, and then sends it to the transmitter for transmission.

First of all, for communication between two terminals that are relatively far away from the signal attenuation distance, it is necessary to perform relay enhancement on the signal on the propagation path, so the base station is required to perform the function of relay enhancement. For communication in a small area, the relay function can be placed in the hand-held mobile terminal, and this device can realize this function. The realization of relay function is the basis of micro-cell transmission. the

In addition, when we coordinate and communicate in a team, there are different priority levels. The invention of our device is based on this requirement. Usually our walkie-talkies can communicate one-to-many, but there is no priority. This device can communicate collectively with devices with higher priority first, and communicate with devices with lower priority through setting. At the same level, point-to-point communication and one-to-many communication are possible. A lower-level device can only communicate with a higher-level device, but cannot communicate beyond the level. the

This requires our equipment to have a high-performance CPU to coordinate the progress of various communications. the

Compared with the prior art, the present invention has the beneficial effects of:

The relay function is placed in the handheld mobile terminal, and the realization is micro-cellular transmission; to ensure the confidentiality of information in the communication, the collective communication can be performed on the devices with relatively high priority first, and the devices with low priority can be communicated through the settings. Communication; peer-to-peer communication and one-to-many communication can be carried out at the same level; lower-level devices can only communicate with higher-level devices, and cannot communicate beyond the level.

Description of drawings

Accompanying drawing 1 is a structural block diagram of an embodiment of the present invention;

Accompanying drawing 2 is the work flowchart of the present invention.

Detailed ways

The internal structure is shown in Figure 1. Since it is a mobile base station and group communication equipment, its specific form is a mobile terminal device, and its specific functions include communication and relay. the

(1) Local communication part:

The signal transmission part of the local communication sends the signal to be transmitted to the transmitter after adding identity and address information.

The signal receiving part of the local communication will share the receiver with the relay part, and then identify the signal, after confirming that it is a local signal, enter the processor, and then output the voice. the

(2) Relay communication part:

After the receiver receives the signal, it recognizes it, and after it is determined that the signal is not received locally, it processes it, filters out the noise and strengthens it, and then sends it to the transmitter for transmission.

(3) Communication methods between devices

As shown in Figure 2, it is assumed that the device priority is pre-divided into three levels, ABC, and each level has three different terminals in use. If A1 needs to communicate with all terminals of B, but the distance is far away, the intermediate terminal can be used for relay, and other level devices cannot receive the communication content sent by A1.

Such a mobile terminal can get rid of the shackles of the base station, independently carry out group communication, and has a relatively confidential priority group communication method, which is superior to broadcast-style walkie-talkies and point-to-point communication mobile phones, and can be widely used in mining areas, tunnels, etc. Operational communication at the site. the
