Detailed ways

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The technical solution of the embodiment of the present invention is applied to the communication scenario shown in FIG. 1 . The broadband communication system and the narrowband trunk communication system are connected by a wide-narrowband system fusion communication link, so that the broadband communication system and the narrowband trunk communication system can communicate with each other. The mobile terminal shown in the figure may be a converged terminal or a narrowband terminal. In the fusion terminal (such as the left mobile terminal in Figure 1), a broadband communication module and a narrowband communication module are integrated, and the broadband communication module can realize the communication between the mobile terminal and the broadband communication system. The narrowband communication module enables communication between the mobile terminal and the narrowband trunking communication system; therefore, the converged terminal can both transmit and receive data through the broadband communication system, and can also transmit and receive data through the narrowband trunking communication system. Moreover, for the same type of data, the converged terminal can be transmitted through the narrowband communication module or through the broadband communication module. In the narrowband terminal (such as the right mobile terminal in FIG. 1), only the narrowband communication module is provided. Therefore, the narrowband terminal can only transmit and receive data in the narrowband trunking communication system.

In the above communication system, the fusion of the broadband communication system and the narrowband trunk communication system is realized, so that the broadband communication system and the narrowband trunk communication system can realize mutual service assistance, that is, the narrowband service data can be transmitted to the narrowband cluster through the broadband communication system. The communication system; correspondingly, the broadband service data can also be transmitted to the broadband communication system through the narrowband trunking communication system. On the other hand, the fusion of the broadband communication system and the narrow-band cluster communication system can make the two complement each other and make up for the shortcomings of the broadband communication system and the narrow-band cluster communication system.

In addition, it should be noted that the broadband communication system in the above communication system may be a broadband trunking communication system or a broadband public network communication system, such as a China Mobile 4G communication system. In fact, any communication system that can provide a wider communication link can replace the above-mentioned broadband communication system and implement the technical solution proposed by the embodiment of the present invention.

The specific process of transmitting narrowband service data in the above communication scenario by using the technical solution of the present invention in the above communication scenario is described by taking the example of the fused terminal (the mobile terminal on the left side of FIG. 1) as shown in FIG. In fact, for any type of mobile terminal, in the fused communication system shown in FIG. 1, data transmission can be implemented by referring to the data transmission process introduced in the embodiment of the present invention.

Referring to FIG. 2, the specific process of data transmission proposed by the embodiment of the present invention is as follows:

When the mobile terminal (replaced by the source terminal for convenience of description) needs to send the narrowband service data information, step S201 is performed to detect whether the source terminal is in the narrowband trunking communication system and the broadband communication system at the same time;

Since the source terminal (the left mobile terminal in FIG. 1) integrates the narrowband communication module and the broadband communication module, the source terminal can separately detect the narrowband trunking communication system signal and the broadband communication system signal. When the source terminal simultaneously detects the narrowband trunking communication system signal and the broadband communication system signal, it can be determined that the source terminal is in the narrowband trunking communication system and the broadband communication system at the same time; if the source terminal only detects the broadband communication system signal, the source terminal can be determined Only in the broadband communication system; if the source terminal only detects the narrowband trunking communication system signal, it can be determined that the source terminal is only in the narrowband trunking communication system.

For a narrowband terminal or a broadband terminal, since its internal communication module is single, it can only detect Signals to a communication system, correspondingly, can only be transmitted and received through a single communication system.

If the source terminal is in the narrowband trunking communication system and the broadband communication system, perform step S202, select a narrowband trunking communication system according to the set link configuration policy, or send the narrowband service data information by using the broadband communication system;

For the converged terminal, the link selection policy can be configured during use, that is, when the converged terminal is in the narrowband trunking communication system and the broadband communication system at the same time, the converged terminal can determine which cluster communication system to send the data transmission strategy. For example, the converged terminal can be preferentially used to transmit data by using the narrowband trunking communication system, and when the narrowband trunking communication system is busy, the broadband communication system is used to transmit data; or the converged terminal is preferentially used to transmit data by using the broadband communication system, when the broadband communication system is busy. , using a narrowband trunking communication system to send data.

According to the link selection policy stored by the source terminal, the source terminal selects a communication system to transmit the narrowband service data information in the broadband communication system and the narrowband trunk communication system. Although the broadband communication system is used to transmit broadband service data, the source terminal can still be set to use the bandwidth resource of the broadband communication system to transmit the narrowband service data information to the broadband communication system by using the broadband communication system as the auxiliary channel. At this time, the broadband communication system The narrowband signaling is transmitted in the middle. Since the broadband communication system and the narrowband trunk communication system have a fusion link, the broadband communication system can conveniently forward the narrowband service data to the narrowband trunk communication system.

It should be noted that, in order to facilitate the transmission of narrowband service data by the source terminal through the broadband communication system, the broadband communication system can distinguish whether the received data information is narrowband service data information or broadband service data information, and the source terminal is transmitting narrowband service data information. When the information header is added, information indicating whether the data information is narrowband service data information or broadband service data information is added.

If the source terminal is not in the narrowband trunking communication system and the broadband communication system at the same time, step S203 is performed to send the narrowband service data information by using the communication system;

It can be understood that when the source terminal is only in a certain communication system, the source terminal transmits the narrowband service data information only by means of the broadband communication system or the narrowband trunking communication system.

Similarly, in order to facilitate the transmission of narrowband service data by the source terminal through the broadband communication system, the broadband communication system can distinguish whether the received data information is narrowband service data information or broadband service data information, and when the source terminal transmits narrowband service data information, Adding information in the header to identify whether the data information is narrowband service data information or broadband service data information.

If the source terminal selects the broadband communication system to transmit the above narrowband service data information, the broadband communication After receiving the narrowband service data information sent by the source terminal in step S204, the system performs step S205, and parses the service type of the received narrowband service data information;

The broadband communication system can determine the service type of the received data information by identifying the information type of the received data information, identifying whether the data information is broadband service data information or narrowband service data information, that is, broadband service data. Information, or narrowband business data information.

If the data information received by the broadband communication system is narrowband service data information, the broadband communication system performs step S206, and sends the narrowband service data information to the narrowband trunking communication system connected to the broadband communication system;

Since the broadband communication system is set up to handle broadband services when it is built, the broadband communication system does not have the capability to process narrowband service data. In the technical solution of the embodiment of the present invention, the bandwidth resource advantage of the broadband communication system is mainly utilized, and the processing authority of the narrowband service data is not completely handed over to the broadband communication system. Therefore, when receiving the narrowband service data information, the broadband communication system forwards the data information to the narrowband trunking communication system, and the narrowband trunking communication system makes a judgment of the next processing.

After receiving the narrowband service data information sent by the broadband communication system or the source terminal, the narrowband trunk communication system performs step S208, parses the received narrowband service data information, and confirms the destination terminal of the narrowband service data information;

Since the broadband communication system does not transmit the broadband service data information to the narrowband trunking communication system, and the mobile terminal does not transmit the broadband service data to the narrowband trunking communication system, the narrowband trunking communication system receives from the mobile terminal or the broadband communication system. The data information must be narrowband service data information that it can handle.

After receiving the narrowband service data information, the narrowband trunking communication system analyzes the data information, obtains the destination terminal information therefrom, and confirms the destination terminal of the data information.

If the destination terminal of the data information is within the scope of the system, step S209 is performed to send the narrowband service data information to the destination terminal;

If the destination terminal of the data information is not within the scope of the system itself, but is in the broadband communication system connected to itself, the narrowband trunking communication system performs step S210, the narrowband service data information, and the destination terminal of the narrowband service data information. Send to a broadband communication system connected to itself;

The narrowband trunking communication system forwards the received data information and the destination terminal information of the data information analyzed and confirmed to the broadband communication system connected to itself, which is equivalent to simultaneously transmitting to the broadband communication system. A delivery instruction is sent to control the broadband communication system to transmit the data information to the destination terminal of the data information in the broadband communication system.

Assuming that the destination terminal of the data information is located in the broadband communication system that transmits the data information to the narrowband trunking communication system, the broadband communication system receives the narrowband service data information sent by the narrowband trunking communication system and the narrowband service through step S211. After the information of the destination terminal of the data information, the process proceeds to step S212, and the narrowband service data information is transmitted to the destination terminal according to the information of the destination terminal of the narrowband service data information.

After receiving the data information sent by the narrowband trunking communication system and the destination terminal of the data information, the broadband communication system is equivalent to receiving the issuing instruction of the narrowband trunking communication system, and transmitting the data information to the system within the scope of the system. The destination terminal of the data information.

It should be noted that, if the source terminal does not send the narrowband service data information through the broadband communication system, when the technical solution of the embodiment of the present invention is actually implemented, steps S204 to S206 are not present. The source terminal directly sends the narrowband service data information directly to the narrowband trunking communication system through step S202 or S203. Starting from step S207, the narrowband trunking communication system or the narrowband trunking communication system cooperates with the broadband communication system to complete the transmission of the data information.

Through the above description of the technical solutions of the embodiments of the present invention, it can be seen that the technical solution of the embodiment of the present invention integrates the narrowband trunking communication system with the broadband communication system, and the narrowband service data information can also be transmitted through the broadband communication system, thereby widening the The bandwidth used to transmit narrowband service data information expands the service capacity of the narrowband system and reduces the narrowband service delay.
