Technical Field

Background

Terrestrial Radio system (TETRA) is a major professional trunked communication system in the world. Currently, external interfaces of different TETRA systems are not uniform, and manufacturers of different TETRA systems do not provide secondary development interfaces, or the cost of secondary development authorization is high, so that people hope to realize interconnection of different network systems by avoiding the use of the secondary development interfaces of the systems.

At present, a communication vehicle-station back-to-back scheme based on vehicle-station tail needle connection is available, and functions of group call voice intercommunication of terminals of cross-communication frequency bands, voice intercommunication in a cluster working mode and a direct working mode and the like can be realized on the premise of not using a secondary development interface of a network system. The basic principle is that the vehicle platforms in two different network systems are interconnected, and terminals in the two different network systems transmit group call data through the interconnected vehicle platforms, so that the interconnection of group call services is realized. However, the above solution can only implement the interconnection of one-way group call service between two network systems, and cannot be used for implementing the interconnection of various different types of services without using a secondary development interface of the system.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention discloses a method for realizing network interconnection, which is shown in figure 1 and comprises the following steps:

s101, receiving service request information of any service type sent by a terminal in a first network system;

specifically, when a terminal in a first network system needs to initiate a service request to a terminal in a second network system, if there is no interconnection channel between the first network system and the second network system, the terminal in the first network system cannot directly send service request information to the terminal in the second network system. Therefore, in the embodiment of the present invention, when a terminal in a first network system initiates a service request to a terminal in an unreachable second network system, the terminal in the first network system is configured to send service request information to a third device between the first network system and the second network system, where the third device is connected to the first network system and the second network system, and the device is used to transfer the service request information sent by the terminal in the first network system to the second network system, thereby indirectly completing interconnection between the first network system and the second network system. That is to say, the idea of the technical solution of this embodiment may be understood as that an interconnection apparatus is disposed between a first network system and a second network system that cannot be interconnected, and the interconnection of the first network system and the second network system is realized through a forwarding connection function of the interconnection apparatus.

It should be noted that, in the embodiment of the present invention, the interconnection apparatus for interconnecting the first network system and the second network system is configured to be capable of implementing forwarding and connection of services of any service type. Therefore, the terminal in the first network system can send the service request information of any service type to the interconnection device, and the interconnection device forwards the service request information to the target terminal in the second network system, thereby realizing the service interconnection of the first network system and the second network system.

The "any service type" is specifically limited to the service types supported by the terminals in the first network system and the second network system, that is, the service interconnection of any service type that can be realized by the technical solution of the embodiment of the present invention means that the service interconnection of any service type supported by the terminals in the first network system and the second network system is realized. For example, the terminal in the first network system may send service request information of the type of single call, group call, short message, status information, packet data, circuit mode data transmission, and the like.

Furthermore, terminal identification information in networks on both sides needs to be written in the home terminal network between different network systems to which the technical solution of the embodiment of the present invention is applied, and each terminal identification information is unique, so that each terminal can explicitly initiate a service request to a terminal of an opposite system. Specifically, when only the service interconnection from the first network system to the second network system needs to be realized, the identification information of all terminals of the first network system and the second network system needs to be written in the first network system at the same time; when the bidirectional interconnection between the first network system and the second network system needs to be realized, the identification information of all terminals in the first network system and the second network system needs to be written in the first network system and the second network system respectively. For example, for a network a and a network B that need to implement bidirectional interconnection, in the network a, identification information of all terminals in the network a and the network B needs to be stored; similarly, in the B network, it is also necessary to store identification information of all terminals in the a network and the B network. Moreover, for the terminals in each terminal group in the a network and the B network, the corresponding group numbers to be interconnected need to be set, so as to selectively realize group call interconnection between the networks on both sides.

S102, analyzing the service request information and confirming a target terminal of the service request information; the target terminal is a terminal in a second network system;

specifically, after receiving service request information sent by a terminal in the first network system, an interconnection device between the first network system and the second network system analyzes the service request information, mainly analyzing to obtain a service type of the service request and a destination terminal.

If the service request information sent by the terminal in the first network system is sent to a terminal in a second network system that can be interconnected with the first network system, for example, the terminal in the second network system roams into the first network system, that is, the destination terminal is in the first network system, then the terminal in the first network system can send the service request information to the destination terminal without using the technical solution of the embodiment of the present invention, but directly through a communication channel in the first network system. Therefore, the technical scheme of the embodiment has a value in realizing interconnection of different network systems without interconnection channels originally. The service request information received by the interconnection apparatus in the embodiment of the present invention is the service request information that the terminal in the first network system wishes to send to the terminal in the unreachable second network system. Therefore, the destination terminal obtained by analyzing the received service request information by the interconnection apparatus is a terminal located in the second network system inaccessible to the first network system.

S103, sending a service request instruction to the destination terminal;

specifically, after the destination terminal of the received service request information is confirmed, the interconnection device sends a service request instruction with the same service type as the service type of the received service request information to the destination terminal in the second network system through the connection with the second network system, and tries to establish service connection with the destination terminal.

And when receiving the service response instruction sent by the destination terminal, executing step S104, and connecting the terminal in the first network system and the destination terminal.

Specifically, when the destination terminal is in an idle state or can respond to a service request instruction sent by the interconnection device, the destination terminal sends a service response instruction to the interconnection device and establishes service connection with the interconnection device. After receiving the service connection of the target terminal, the interconnection device connects the terminal in the first network system initiating the service with the target terminal, so that the terminal in the first network system initiating the service is in service connection with the target terminal. The connecting the terminal in the first network system initiating the service with the destination terminal includes sending a service response message to the terminal in the first network system initiating the service, and establishing a wireless connection or an audio connection for the terminal in the first network system and the destination terminal.

On the contrary, if the interconnection device does not receive the service response instruction of the destination terminal within the set time period, the interconnection device sends information to the terminal in the first network system initiating the service to inform that the service connection cannot be completed.

Further, if the terminal in the first network system initiating the service and the destination terminal implement the voice service, the interconnection device establishes a voice relay connection for the terminal in the first network system initiating the service and the destination terminal by using the audio connection module of the interconnection device. If the terminal in the first network system initiating the service and the target terminal implement the non-voice service, the interconnection device establishes a wireless connection for the terminal in the first network system initiating the service and the target terminal.

It should be noted that, with the technical solution of the embodiment of the present invention, after receiving the service request information sent by the terminal in the first network system, the interconnection apparatus does not directly send the service request to the destination terminal, but actively sends a service request instruction to the destination terminal, and when receiving a service response instruction sent by the destination terminal, that is, when it is determined that the destination terminal is idle or can receive the service request, connects the destination terminal with the terminal of the first network system that initiates the service request. And if the service response instruction sent by the destination terminal cannot be received, informing the first network system terminal initiating the service that the service connection cannot be realized. By adopting the scheme, the occurrence of interconnection false images can be effectively prevented, and the real and effective service interconnection between the service initiating terminal and the service receiving terminal is ensured.

When the technical scheme of the embodiment of the invention is applied to realize network interconnection, firstly, service request information of any service type sent by a terminal in a first network system is received; then, analyzing the service request information and confirming a target terminal of the service request information; the target terminal is a terminal in a second network system; finally, a service request instruction is sent to the destination terminal; and when receiving a service response instruction sent by the target terminal, connecting the terminal in the first network system with the target terminal. By adopting the technical scheme, when a service request of any service type sent by the terminal in the first network system to the inaccessible second network system is received, the request information is analyzed to determine the target terminal, then a service request instruction is sent to the target terminal, and the terminal in the first network system and the target terminal in the second network system are connected after the response instruction of the target terminal is received, so that the service connection of any service type between the terminal in the first network system and the target terminal is realized, and the interconnection among different network systems is realized.

Optionally, in another embodiment of the present invention, the receiving service request information of any service type sent by a terminal in a first network system includes:

correspondingly, the sending the service request instruction to the destination terminal includes:

Specifically, referring to fig. 2, an interconnection apparatus configured to implement interconnection between a first network system and a second network system in the embodiment of the present invention includes a first number of first terminal modules and a second number of second terminal modules. The first number of first terminal modules is a first number of terminal modules having components such as independent baseband, radio frequency unit, antenna, independent serial peripheral, and the like, and may specifically be a multi-mode terminal or an independent terminal. Similarly, the second number of second terminal modules is a second number of terminal modules having components such as independent baseband and rf units, antennas, independent serial peripherals, and the like, and may specifically be a multi-mode terminal or an independent terminal.

In addition, the interconnection device also comprises interconnection control software which is used for realizing the connection control of the first terminal module and the second terminal module, controlling signaling and message forwarding at the same time, realizing the control of various types of service interconnection of the first network system and the second network system, and the like. The interconnection control software can be used as the central control software of the interconnection device, and is used for analyzing various information and signaling received by the device and making a decision and control on the whole work of the interconnection device.

In the embodiment of the present invention, when the service request information sent by the terminal in the first network system to the terminal in the second network system is set to be unreachable, the service request information is transferred to the first terminal module of the interconnection apparatus, so that the interconnection apparatus in the embodiment of the present invention can receive the service request information sent by the terminal in the first network system through the first terminal module, and continue to execute the technical solution in the embodiment of the present invention, thereby implementing service interconnection between the first network system and the second network system.

In fact, the first terminal module and the second terminal module are terminal modules having the same function and the same composition structure. The difference is that the first terminal module mainly realizes the connection with the first network system, and the second terminal module mainly realizes the connection with the second network system. For convenience of difference description, the embodiment of the present invention designates a terminal module connected to a first network system as a first terminal module, and designates a terminal module connected to a second network system as a second terminal.

Each of the first terminal modules has the same function and may be configured to receive service request information sent by a terminal in the first network system, so that the interconnection apparatus may receive the service request information sent by the terminal in the first network system through any one or any plurality of first terminal modules in the first number of first terminal modules. When the interconnection apparatus receives the service request information sent by the terminal in the first network system through the plurality of first terminal modules, the synchronous reception of the multiple paths of service request information is actually realized. Similarly, each of the second terminal modules has the same function and can be used to send a service request instruction to the terminal in the second network system, so that the interconnection apparatus can send a service request instruction to the destination terminal in the second network system through any one of the second number of second terminal modules or any plurality of second terminal modules. When the interconnection apparatus sends a service request instruction to the terminal in the second network system through the plurality of second terminal modules, a multi-path concurrent service request is actually realized.

In the embodiment of the present invention, the numbers of the first terminal module and the second terminal module are respectively a first number and a second number, and the specific number may be set according to an actual interconnection communication demand. Each first terminal module and each second terminal module need to have a mutual corresponding relationship, that is, for each first terminal module, at least one second terminal module needs to correspond to the first terminal module and can establish connection with the first terminal module, and when the first terminal module receives service request information of the first network system, a service request instruction is sent to the second network system through the second terminal module connected with the first terminal module, so that the first network system and the second network system can be interconnected through a connection link between the first terminal module and the second terminal module. Similarly, for each second terminal module, at least one first terminal module is associated with it and is able to establish a connection with it. And an audio connection link capable of controlling on-off is arranged between the first terminal module and the second terminal module which can be interconnected, so that audio communication between the first network system and the second network system is realized.

A simpler way is to configure the same number of first terminal modules (a 1, a 2, a 3, a 4) and second terminal modules (b 1, b 2, b 3, b 4) for the interconnect device, and to set a one-to-one correspondence between the first terminal modules and the second terminal modules (a 1 to b1, a 2 to b 2, a 3 to b 3, a 4 to b 4), as referred to the way shown in fig. 2. In this way, for any first terminal module, when it receives the service request information sent by the first network system, it sends the service request instruction to the destination terminal in the second network system through the second terminal module uniquely corresponding to it. And a controllable audio connection link is configured between each pair of corresponding first terminal module and second terminal module for implementing audio communication between the first network system and the second network system.

Optionally, in another embodiment of the present invention, the receiving, by a first terminal module with a set first number, service request information of any service type sent by a terminal in a first network system includes:

correspondingly, the sending a service request instruction to the destination terminal through a second set number of second terminal modules includes: and sending a service request instruction to the destination terminal through a second terminal module corresponding to the first terminal module for receiving the service request information.

Specifically, in the interconnection apparatus in the embodiment of the present invention, the first terminal module and the second terminal module have a corresponding relationship, and therefore, after receiving the service request information sent by the terminal in the first network system through a certain first terminal module, a service request instruction needs to be sent to a destination terminal of the service request information through the second terminal module corresponding to the first terminal module (i.e., having a connection relationship). After receiving the service response instruction sent by the destination terminal, the service interconnection between the terminal in the first network system and the destination terminal in the second network system is quickly established through the corresponding (i.e. having the connection relation) first terminal module and second terminal module.

Optionally, in another embodiment of the present invention, when the first terminal module receiving the service request information is in a busy service state, the first terminal module receiving the service request information transfers the received service request information to other first terminal modules in the first number of first terminal modules.

Specifically, in the embodiment of the present invention, a busy transfer function is set for a first number of first terminal modules, that is, after the first terminal module receives service request information sent by a terminal in a first network system, if the first terminal module is in a busy service state and cannot process the request information, the first terminal module forwards the service request information to other first terminal modules. For example, referring to fig. 2, if a1 receives service request information sent by a terminal in a first network system, but a1 is in a busy state, the a1 forwards the service request information to a 2, if a 2 is also in a busy state, the a 2 forwards the request information to a 3, and so on.

In order to more vividly and specifically introduce the technical solution of the embodiment of the present invention, the following describes, by way of specific example, a process of implementing service interconnection between different network systems by using the technical solution of the embodiment of the present invention.

In the system architecture shown in fig. 2, it is assumed that an a1 terminal in an a network system wants to send a duplex single call service request to a B1 terminal in an unreachable B network system, as shown in fig. 3, the specific process is as follows: a1 sending duplex single call request information to A1 of the interconnection device; after receiving the request information, the first 1 informs the interconnection control software of receiving the duplex single call request information sent by the A1, and simultaneously sends the request information to the interconnection control software; if the A1 is busy, the A1 forwards the request information to the A2, and after the A2 receives the request information, the A2 informs the interconnection control software of receiving the duplex single call request information sent by the A1 and simultaneously sends the request information to the interconnection control software; the interconnection control software analyzes the duplex single call request information and confirms that the target terminal is B1; then the interconnection control software controls B1 (B2 when A1 is busy) to set call parameters and sends a duplex single call request instruction to B1; b1, after receiving the command, responding to the command and sending a duplex single call response command to B1 (B2 when A1 is busy); and B1 (B2 when A1 is busy) informs the interconnection control software to control A1 (B2 when A1 is busy) to send duplex single-call response information to A1 after receiving the duplex single-call response instruction, and at the moment, the audio connection between A1 and B1 enables the A1 and B1 to realize normal voice receiving and sending, so that duplex single-call service connection between the first network system and the second network system is realized.

According to the above exemplary procedure for implementing duplex single call service connection, half-duplex single call service connection between the first network system terminal and the second network system terminal can also be implemented, and the specific process is similar to the above processing process, and is not described in detail here. It should be noted that, for the half-duplex single call service without feedback, referring to the above exemplary process, when implementing the half-duplex single call service connection, after B1 (B2 when a1 is busy) sends the half-duplex single call request to the B network system, if receiving the half-duplex call establishment notification information sent by the B network system, it indicates that the half-duplex single call service connection is completed, and it is not necessary to control a1 (a 2 when a1 is busy) to send the response information to the a network.

Assuming that an a1 terminal in the a network system wants to send a group call service request to an X group terminal in the unreachable B network system, referring to fig. 4, the implementation process is: a1 sends X group calling request information to A1; after receiving the request information, the first 1 informs the interconnection control software to receive the X group calling request information sent by A1, sends the request information to the interconnection control software, and establishes group calling with A1; if the A1 is busy, the A1 forwards the request information to the A2, and after the A2 receives the request information, the A2 informs the interconnection control software to receive the X group calling request information sent by the A1, simultaneously sends the request information to the interconnection control software, and establishes group calling with the A1; the interconnection control software analyzes the group calling request information of the X group and confirms that the target terminal is the terminal of the X group in the B network system; then, the interconnection control software controls a group B1 (a group B2 when the group A1 is busy) to set call parameters and sends a group call request instruction to the group X terminals; after receiving the instruction, the X group terminal in the B network system establishes a group call, and meanwhile, the B1 receives the notification information that the call sent by the B network system is established. To this end, group call is established between group a1 and group X terminals in the B network system, and the audio connection between a1 (a 2 when a1 is busy) and B1 (B2 when a1 is busy) enables the group call to receive and transmit voice normally.

Assuming that an a1 terminal in the a network system is to send a circuit mode data call request to a B1 terminal in the unreachable B network system, as shown in fig. 5, the implementation process is: a1 sending circuit mode data call request information to A1 of the interconnection device; after receiving the request information, the first 1 informs the interconnection control software of receiving the circuit mode data call request information sent by the A1, and simultaneously sends the request information to the interconnection control software; if the first 1 is busy, the first 1 forwards the request information to the first 2, and after the first 2 receives the request information, the interconnection control software is informed of receiving the circuit mode data call request information sent by the A1 and simultaneously sends the request information to the interconnection control software; the interconnection control software analyzes the circuit mode data call request information and confirms that the destination terminal is B1; then, the interconnection control software controls a second 1 (a second 2 when the first 1 is busy) to set call parameters, sends a circuit mode data call request instruction to a B1 and simultaneously starts a circuit mode data transmission working mode; b1 receives the command, responds to the command, and sends a circuit mode data call response command to B1 (B2 when A1 is busy); then the interconnection control software controls the A1 (A2 when the A1 is busy) to send circuit mode data call response information to the A1, and controls the A1 (A2 when the A1 is busy) to start a circuit mode data transmission working mode. To this end, a circuit mode data call connection is established between a1 and B1, a1 sends circuit mode data to a1, a1 forwards the data to B1, and B1 forwards the data to B1, thereby realizing data transmission from a1 to B1. Conversely, B1 may also transmit data to a1 via this path. It should be noted that, when the terminal of the first network system and the terminal of the second network system establish the circuit mode data transmission service, the voice connection before the first network system and the second network system is not needed to transmit the voice data, and only the wireless or wired connection between the first network system and the second network system is realized, so that the data can be transmitted between the first network system and the second network system 1.

Optionally, in another embodiment of the present invention, when the service request information is a request information for sending a short message or status information, the sending a service request instruction to the destination terminal through a second set number of second terminal modules includes:

Specifically, if the service request information sent by the terminal in the first network system to the terminal in the second network system is a request for sending a short message or status information, the second terminal module of the interconnection device is not required to send a service request instruction to the terminal in the second network system in the whole service connection implementation process, and the short message or status information to be sent is directly sent to the terminal in the second network system through the second terminal module.

When the short message or the state information is sent, the wireless connection or the audio connection is not needed to be established between the first network system terminal and the second network system terminal, but only the information forwarding is realized, so that when the first terminal module receives the short message or the state information, any idle second terminal module is selected to send the short message or the state information to the target terminal.

Optionally, in another embodiment of the present invention, when the service request information is short message information or status information, if all the second terminal modules of the second number of second terminal modules are occupied, the received short message information or status information is stored, and the stored short message information or status information is sent through the idle second terminal module when waiting for the idle second terminal module.

Specifically, the interconnection control software of the embodiment of the present invention has a storage function, and when all the second terminal modules are busy and cannot send short messages or status information, the interconnection control software temporarily stores the short messages or status information, and when an idle second terminal module is waited for, sends the stored short messages or status information to the destination terminal through the idle second terminal module.

The short message service is divided into a single short message service and a group short message service. The service implementation process of the single short message is similar to the process of implementing the single call service, and the phenomenon that the first terminal module forwards the short message to other first terminal modules when the first terminal module is busy also exists. Different from the process of realizing the single call service, when the single short message is forwarded, the short message is directly sent to the target terminal through the idle second terminal module without sending a request instruction to the target terminal in the second network system. The realization process of the group short message service is more concise, when the terminal of the first network system terminal sends the group short message, all the first terminal modules receive the group short message, any first terminal module receiving the short message sends the short message to the idle second terminal module, and the idle second terminal module sends the group short message to each destination terminal.

For example, assuming that an a1 terminal in an a network system is to send a short message or status information to a B1 terminal in an unreachable B network system, a1 sends a short message to a 1; the first 1 forwards the short message to interconnection control software after receiving the short message, and the interconnection control software analyzes the short message to confirm that the target terminal is B1; then the interconnection control software judges whether an idle second terminal module exists, if not, the short message is temporarily stored, and the subsequent operation is executed after waiting for the idle second terminal module; if the second terminal module is idle, selecting one idle second terminal module optionally, controlling the second terminal module to set the short message parameters, and sending the short message content to B1; b1 sending message sending success report to the second terminal module sending message after receiving message; the control software controls the A1 to send a short message sending success report to the A1.

Optionally, in another embodiment of the present invention, the method further includes:

Specifically, with the technical solution of the embodiment of the present invention, after establishing service connections for the terminal in the first network system and the terminal in the second network system, if a service ending instruction sent by the terminal in the first network system is received, or a service timeout hang-up instruction sent by the system is received, it may be considered that the terminal in the first network system has already exited the service at this time, the interconnection apparatus sends a service ending instruction to the destination terminal, so that the destination terminal also exits the service, thereby ending the service connection between the terminal in the first network system and the destination terminal.

Optionally, in another embodiment of the present invention, the sending the service ending instruction to the destination terminal includes:

and sending a service ending instruction to the destination terminal.

Specifically, in the embodiment of the present invention, after receiving a service end instruction sent by a terminal in a first network system, when sending the service end instruction to a destination terminal, first, it is detected and determined whether the terminal and the destination terminal in the first network system are in a circuit mode data transmission state. If the terminal and the destination terminal in the first network system are in the circuit mode data transmission state, firstly sending an instruction to the terminal and the destination terminal in the first network system to enable the terminal and the destination terminal in the first network system to exit the circuit mode data transmission state, and then sending a service ending instruction to the destination terminal.
