Description
Technical Field
The invention relates to the field of communication talkback, in particular to a communication method of public network talkback and traditional talkback based on a single-terminal gateway.
Background
Traditional talkbacks (such as TETRA, PDT, DMR) can not only establish a private network and implement trunking talkback within the coverage area of the private network, but also implement direct talkback (including wireless analog talkback) between terminals when there is no network signal, or extend the distance of direct talkback between terminals through relays. The coverage range of the traditional talkback is limited by a direct distance or a self-built private network coverage range, generally achieves coverage of a city or a region level, and is difficult to achieve national coverage.
The public network talkback depends on a wireless data network (hereinafter referred to as a network) of an operator as a data link transmission layer, and realizes a cluster talkback function in a wide area range in a range covered by an IP network. But in the case of no network, public network talkback cannot be used.
In actual use, under the condition of no network, the traditional talkback is a good complement of the public network talkback. In the presence of a network, the wide area coverage characteristic of public network talkback is a good extension of traditional talkback. Therefore, on the basis of public network talkback coverage, the talkback gateway is deployed in the region which can not be covered by the public network, interconnection and intercommunication between the traditional talkback and the public network talkback are achieved, the effect of extending public network talkback coverage can be achieved, and the method is a universal choice in the industry.
The current talkback gateway is realized by placing terminals or modules of two different talkback systems together, and outputting an electric signal to trigger a talkback key of a terminal or module of a second system when the terminal or module of a first system receives talkback and plays voice, so that the terminal or module of the second system can acquire the voice played by the terminal or module of the first system and send the voice to the second talkback system, and the aim of transmitting the talkback voice of the first system to the second system is fulfilled; vice versa, the same is true for the implementation. Such a gateway, whether it appears to be not a whole in appearance, is actually a physical connection made using terminals or modules of two different systems. The connection mode between two terminals or modules may not be limited to electrical signals, but may have various physical or logical connection modes, for example, a serial port, an IP protocol, etc. may be used to notify a key signal. But two terminals or modules, which are essentially two terminals or modules controlled by separate central control units. For the gateway thus implemented, we call it a dual-termination gateway. The dual-terminal gateway is not easy to carry and has higher cost.
The coverage area of the public network is not constant, and the coverage area of the public network is changed into the coverage area without the public network due to network congestion or the fact that the terminal moves into a sheltering area. And if the terminal enters the area without public network coverage, the gateway service can not be provided any more. Even if a standby gateway exists at this time, people need to know the condition that the gateway does not work and manually switch. How is the best network selected from the standby gateways at the time of handover? After the switch, if the original gateway recovers its function and conflicts with the standby gateway, how to do it? These are all real problems. In summary, in the process of implementing the technical solution of the present invention, the inventors of the present application find that the above-mentioned technology has at least the following technical problems:
in the prior art, intercommunication and interconnection between the traditional intercom system and the public network intercom system are realized by deploying a double-terminal gateway, so that the technical problems of inconvenient carrying and high cost exist.
In addition, the conventional dual-terminal gateways are all statically configured gateways, and cannot dynamically adapt to the change of the network coverage environment: the problem that the gateway service conflicts and the like exists even if a standby gateway exists, the switching cannot be timely and effectively carried out, the optimal standby gateway cannot be selected during the switching, or after the standby gateway is switched to and the original gateway is recovered.
Disclosure of Invention
The invention provides a public network talkback and traditional talkback communication method based on a single-terminal gateway, which solves the problems that the intercommunication interconnection between the traditional talkback system and the public network talkback system in the prior art is not convenient to carry due to the adoption of a double-terminal gateway, the cost is higher, and the gateway cannot dynamically adapt to the change of network coverage.
In order to solve the technical problems, the application provides a public network talkback and traditional talkback communication method based on a single-terminal gateway, wherein the method is used for enabling a public network talkback system and a traditional talkback system to communicate through the single-terminal gateway; the single-terminal gateway is a terminal K in a public network intercom system and a traditional intercom system; the terminal K can work in a public network talkback mode and a traditional talkback mode simultaneously; the terminal K can become a gateway through static configuration and dynamic selection.
The invention realizes a single-terminal gateway based on a dual-mode terminal which can work in the traditional talkback and the public network talkback. Not only can a single terminal be deployed as a gateway by using the existing static configuration mode, but also the most suitable terminal can be dynamically selected and temporarily deployed as the gateway by combining the geographical position information. In fig. 1, C, D or E can be dynamically used as a gateway as required, thereby achieving A, B, C, D, E, M, N simultaneous intercommunication.
According to the single-terminal gateway provided by the invention, two talkback modes are used and switched in the same terminal. The gateway may be deployed in a static configuration or may be dynamically generated by the system according to an algorithm. Therefore, in the coverage range of public network talkback, possible terminals can be found near any person needing to communicate, and the terminals are dynamically designated as gateways, so that intercommunication and interconnection are achieved. Meanwhile, a plurality of gateways can exist in the system at the same time, and a plurality of traditional talkback areas are communicated at the same time.
Furthermore, the terminal K can become a gateway through static configuration, and can also be selected to become a single-terminal gateway by a public network intercom system through combining position information.
Furthermore, the dynamic single-terminal gateway can move and can normally provide gateway service in the moving process.
Further, the working process of the terminal K becoming the dynamic single-terminal gateway is as follows:
firstly, judging whether the terminal K becomes a gateway or not, if so, improving the talkback priority level of the terminal K in the public network;
then judging the specific talkback mode of the terminal K receiving the voice;
if the voice is in the traditional talkback mode, the terminal K opens a sending channel of the public network talkback mode and then forwards the voice received in the traditional talkback mode to a public network talkback system;
if the public network talkback mode is adopted, the terminal K opens a sending channel of the traditional talkback mode and then forwards the voice received by the public network talkback mode to a traditional talkback system.
Further, the process of dynamically selecting the terminal K as the dynamic single-terminal gateway by the public network intercom system is as follows:
the terminal in the gateway mode within the public network talkback coverage reports the position of the terminal to the server at any time, the terminal keeps connection with the server, the server marks the state of the terminal keeping connection as on-line, and marks the state of the terminal losing connection as off-line;
being in gateway mode does not mean that it is currently a gateway, and being in gateway mode merely marks: 1) the method comprises the steps that a server is required to detect whether the server is online or not, and if the server is not online, the server is required to search a terminal which can communicate with the server and designate the terminal as a gateway; 2) the terminal can be selected as a gateway by the server; 3) a terminal in gateway mode can only send on one mode when pressing PTT key for talkback, on public network talkback mode when it is on-line, and on traditional talkback mode when it is off-line.
When a server detects that a certain terminal in a gateway mode is disconnected, a communication area is determined based on the traditional talkback coverage range by taking the position reported by the terminal last as the center;
in the communication area, if no gateway exists currently, the server selects an online terminal J which is closest to the offline person, is not in the communication area of any existing gateway and is in a gateway mode, sends an instruction to enable the terminal J to become a gateway, and binds the service relationship between the gateway and the offline terminal;
in the communication area, if a gateway exists at present, the server binds the service relationship between the gateway and the offline terminal; when finding that the disconnected terminal is online again, the server releases the service relationship bound between the terminal and the gateway;
when the gateway binding the service relationship moves out of the communication area of the dropped terminal, the service relationship between the gateway and the dropped terminal needs to be released, and the gateway is selected again in the communication area of the terminal releasing the service relationship.
When the gateway does not have any bound service relationship, the server informs the gateway to exit the gateway, and the gateway becomes a common terminal staying in the gateway mode.
Furthermore, one gateway can bind service relationships with a plurality of dropped terminals.
Further, the processing flow when the dynamic single-terminal gateway is disconnected is as follows:
when the terminal as the gateway is disconnected, the terminal also exits the gateway to become a common terminal staying in a gateway mode, and the server marks the terminal to exit the gateway; when the server finds that the gateway is disconnected, the server selects an online terminal which is closest to the disconnected gateway and is in a gateway mode as a substitute gateway in a communication area of the gateway;
and the server transfers all the service relationships bound by the disconnected gateway to the alternative gateway, and uses the disconnected gateway as a disconnected terminal and binds the service relationships with the alternative gateway.
The terminal can work in a public network talkback mode and a traditional talkback mode simultaneously, and specifically detects a network where the terminal is located to obtain a network type of an intercom system supported by a region where the terminal is located; and the terminal is switched to a corresponding working mode based on the obtained talkback system network type, and works according to a protocol specified by the mode when the working mode needs talkback. The network types of the intercom system include: the system comprises a public network intercom system based on WCDMA/EVDO/TD-SCDMA/TDD-LTE/FDD-LTE and a traditional intercom system based on DMR/TETRA/PDT/analog intercom. The single-terminal dynamic gateway in the application is a dual-mode single terminal, the dual modes work in a public network talkback mode and a traditional talkback mode simultaneously, and a traditional talkback system and a public network talkback system are both composed of corresponding talkback terminals and networks.
One or more technical solutions provided by the present application have at least the following technical effects or advantages:
because only one terminal is adopted to communicate as the dynamic single-terminal gateway, and the dynamic single-terminal gateway can move and can dynamically select and configure, the technical problems that the existing intercommunication interconnection between the traditional intercom system and the public network intercom system is inconvenient to carry due to the adoption of a double-terminal gateway, the cost is high, and the change of the network coverage environment cannot be automatically adapted are solved.

Detailed Description
The invention provides a public network talkback and traditional talkback communication method based on a single-terminal gateway, which solves the technical problems that the cost of a double-terminal gateway is higher and the gateway cannot be dynamically switched according to the network coverage change in the intercommunication and interconnection between the traditional talkback system and the public network talkback system in the prior art, realizes the intercommunication and interconnection between the traditional talkback system and the public network talkback system which are completed by the single-terminal gateway in the method, has lower cost, and has the technical effects of dynamically selecting a proper gateway according to an algorithm and adapting to the network coverage change.
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflicting with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described and thus the scope of the present invention is not limited by the specific embodiments disclosed below.
The dual-mode single terminal, namely the dynamic single terminal gateway, can become a gateway through static configuration, and can also become a gateway through dynamic selection by a server side through an algorithm in combination with the position information.
The terminal becomes a gateway for providing a service after becoming a gateway. The work flow supports that the voice received from the traditional talkback mode is sent through the public network talkback mode; otherwise, the voice received from the public network talkback mode is sent through the traditional talkback mode. The terminal which becomes the gateway needs to improve the talkback priority of the terminal in the public network so as to ensure that the talkback of the public network can be interrupted in a robbing way and the voice forwarding is completed. The work flow refers to fig. 2.
The single terminal which becomes the gateway can still move like a common mobile terminal, and normally provides gateway service in the moving process.
Referring to fig. 3, the system dynamically selects a gateway as follows:
1, the terminal in the public network talkback coverage reports the position of the terminal (GPS/Beidou) to the server at any time and keeps connection with the server. The server marks the state of the terminal which keeps connection as online and the state of the terminal which loses connection as offline.
And 2, when the server detects that a certain terminal is disconnected, determining a communication area based on the traditional talkback coverage range (such as a direct talkback range of 1-3 KM) by taking the position reported by the terminal last as the center.
3.1 in the communication area, if no gateway exists at present, the server selects an online terminal which is closest to the offline person, is not in the communication area of any existing gateway and is in a gateway mode, sends an instruction to enable the online terminal to become a gateway, and binds the service relationship between the gateway and the offline terminal.
3.2 in the communication area, if the gateway exists at present, the server binds the service relationship between the gateway and the disconnected terminal. One gateway can bind service relations with a plurality of dropped terminals.
And 4, when the server finds that the disconnected terminal is online again, releasing the service relation bound between the terminal and the gateway.
And 5, when the gateway bound with the service relationship moves out of the communication area of the dropped terminal, the service relationship between the gateway and the dropped terminal needs to be released, and the gateway is selected in the communication area of the terminal with the service relationship released again.
6, when the gateway does not have any bound service relationship, the server informs the gateway to exit the gateway and becomes a normal terminal staying in the gateway mode.
Referring to fig. 4, the gateway needs to remain online to provide services, and when the gateway is disconnected, the process flow is:
1, when the gateway is disconnected, the gateway needs to automatically quit the gateway, namely, the gateway is automatically quitted to be the disconnected terminal in the gateway mode.
2, when the server finds that the gateway is disconnected, the server needs to select an online gateway mode terminal closest to the disconnected gateway as a substitute gateway in the communication area of the gateway.
And 3, the server transfers all the service relationships bound by the disconnected gateway to the alternative gateway, and the disconnected gateway is used as the service relationship bound by the disconnected terminal and the alternative gateway.
Because only a single terminal is adopted as a gateway for communication, and the single terminal gateway can move and can be combined with position information to dynamically select and switch by a public network talkback server, the technical problems that the existing intercommunication interconnection between a traditional talkback system and a public network talkback system adopts a double-terminal gateway, which is inconvenient to carry, has higher cost and cannot automatically adapt to the change of network coverage environment are solved, the intercommunication interconnection between the traditional talkback system and the public network talkback system which are completed by adopting the single terminal gateway is realized, the cost is lower, and the technical effect of dynamically selecting a proper gateway according to an algorithm to adapt to the change of the network coverage environment is achieved.
