Description

Dynamic grouping method, system and terminal

The present invention relates to the field of communication technologies, and more particularly to a dynamic grouping method, system and terminal. Background technique

The cluster communication system was born in the late 1970s and early 1980s. Its working mode is similar to the telephone exchange system, which automatically provides users with designated channels for calling and other services. The basic principle of the cluster system is that the central controller centrally controls and manages each channel in the system. When the user initiates a call, the idle channel is quickly and dynamically allocated to the user. After the call ends, the channel is automatically reclaimed for waiting. User usage greatly improves channel usage. After years of development, emergency calls and group calls have become the most commonly used functions in cluster systems. As business needs increase, the ability to quickly establish calls, prioritize, and dynamically group is also a major requirement for cluster systems.

The group call in the cluster service is to group some members of the system, so that the group call function can pre-set fixed group information and corresponding group member information at the same time. When a group call is directly initiated during application, the group members can be commanded and dispatched. Group calls in cluster services are divided into static groups and dynamic groups (also known as temporary groups). A static group is a set of fixed group information and corresponding group member information in the system. When a group call is directly initiated, the group members can be scheduled and dispatched, and the dynamic group is temporarily grouped according to the temporary needs of the service site to achieve the purpose of group call scheduling.

In the existing individual cluster communication system, the main group unit sends a dynamic grouping instruction to the participant's signaling channel through the cluster system dispatching station or the management terminal, and assigns the dynamic group number to the participant (for example, in the public security application, the temporary organization Police Action Team No.). Once the task is completed, the action team is disbanded, and the dispatching station or management terminal cancels the dynamic group.

In the existing cluster system, due to the number of channels and bandwidth limitations of the cluster system, the following defects exist:

The signaling length in the signaling channel is limited due to the instruction of the dynamic grouping sent by the cluster system dispatching station. System, which limits the number of dynamic group members when sending dynamic grouping instructions. Summary of the invention

The technical problem to be solved by the present invention is to provide a dynamic grouping method, system and terminal for the defects of the above-mentioned dynamic group members of the prior art, such as limited number of dynamic group members, low scheduling efficiency and poor flexibility.

a master control server, configured to generate a grouping instruction according to the grouping request input by the client, and send the grouping instruction to the access server, where the grouping instruction includes a temporary group group number and a terminal corresponding to the temporary group group number;

And an access server, configured to receive the grouping instruction, and send the grouping instruction to the terminal through the mobile communication network, so that the terminal that receives the grouping instruction writes the temporary group group number into the group list to which it belongs.

The present invention also constructs a terminal, where the terminal includes:

a receiving unit, configured to receive a grouping instruction sent by the access server by using a mobile communication network, where the grouping instruction includes a temporary group number and a terminal corresponding to the temporary group number;

Public network for functions such as GPRS, CDMA, GSM and 3G) Transfer the grouping instructions of the temporary group, The cluster network makes a call to the terminal in the corresponding temporary group. In this way, the grouping instruction and the call instruction are sent by different networks, so that the number of terminals of the established temporary group is not limited by the signaling length, and the use of the wireless dispatching station solves the problem that the grouping instruction can only be sent through the cluster system dispatching station. technical problem. The technical scheme of the invention is very flexible and has high scheduling efficiency.

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

FIG. 1 is a flow chart of a dynamic grouping method 100 according to an embodiment of the invention. Referring to FIG. 1, in step 101, the master server generates a grouping instruction according to the grouping request input by the client and sends the grouping instruction. a group instruction, where the grouping instruction includes a temporary group number and a terminal corresponding to the temporary group number. The terminal corresponding to the temporary group number may be one of the terminals or multiple terminals in the temporary group, and the specific manner is not limited.

The client can be a visual scheduling software installed on the computer, and the user who installs the software (for example, but not limited to the public security department) performs the scheduling operation through the software's visual scheduling interface. The visual scheduling interface can display the location of each terminal by region. Each terminal is displayed as an icon on the interface, and of course, other display modes, and the present invention is not limited thereto. The user can form a temporary group by arbitrarily selecting the terminals of each area in the visual scheduling interface. For example, the Shenzhen Public Security Bureau has set up 50 terminals in Futian District. If there is an emergency in a residential area in Futian District, the Municipal Public Security Bureau can immediately select the holdings of the nearest terminals in Futian District from the nearest district through the visual scheduling interface. The icon of the multiple terminals constitutes a temporary group to perform an emergency task, generates a temporary scheduling group list and group member information, and selects a temporary group number that has been registered for the temporary group.

The user can also form a temporary group by arbitrarily selecting the desired terminal in the visual scheduling interface. For example, the Shenzhen Public Security Bureau Futian District has a criminal investigation team 1 (including team members A, B), and Nanshan District has a criminal investigation team 2 (including group members C, D, E), if Shenzhen surrounding cities such as Huizhou City In the case of extraordinarily large criminal cases, senior personnel are urgently needed to support them. Suppose that team member A and group members C and D are experienced investigators, they can immediately select the group A, C, and D icons through the visual scheduling interface to form a temporary group to support the detection of the mega-criminal case. The temporary scheduling group list is generated, and the list includes the group number of the temporary group and the terminal corresponding to the temporary group number (that is, the group member information of the temporary group), and the registered temporary group number is selected for the temporary group. The general cluster network will set a certain number of temporary group numbers that can be used in the cluster network. When the client needs to establish a temporary group, you can select one or more temporary group numbers.

In step 102, the access server receives the grouping instruction output by the master server and sends the grouping instruction to the terminal through the mobile communication network, so that the terminal receiving the grouping instruction writes the temporary group number to the terminal In the list of groups to which it belongs.

The composition of the grouping instruction may have various forms. In an embodiment of the invention, the grouping instruction includes a temporary group number and a terminal number. When the grouping instruction is sent to the terminal, it is sent only to the terminal belonging to the temporary group, and only the terminal belonging to the temporary group can receive it. Assume that the terminal is eight. C, D belong to the member of the temporary group 10000001, then the grouping instruction sent to terminal A is 10000001A, the grouping instruction sent to terminal C is 10000001C, and the grouping instruction sent to terminal D is 10000001D. The representation of the grouping instructions herein is merely an example and is not intended to limit the invention. After receiving the grouping instruction, the terminal parses the grouping instruction, obtains the temporary group number corresponding to the grouping instruction, and writes the temporary group group number into the group list to which it belongs, and can accept the calling task of the wireless dispatching station at any time. In addition to being sent separately, it can of course be implemented by using the group sending method. All terminals can receive the grouping instruction, but only the members belonging to the temporary group write the temporary group number in the group list to which they belong, which is not temporary. The group's terminal ignores the grouping instruction. This method is a waste of resources and increases processing costs, so it is not a preferred method.

In another embodiment of the present invention, the grouping instruction may include a temporary group number and a number of the plurality of terminals. When the grouping instruction is sent, only the terminal belonging to the temporary group is separately sent, and only the terminal belonging to the temporary group Can receive it. Assuming that the terminal VIII and C belong to the member of the temporary group 10000001, the grouping instruction sent to the terminals A and C is 10000001AC. The representation of the grouping instructions herein is merely an example and is not intended to limit the invention. After receiving the grouping instruction, the terminal parses the grouping instruction, obtains the temporary group number corresponding to the grouping instruction, and writes the temporary group group number into the group list to which it belongs, and can accept the calling task of the wireless dispatching station at any time. Of course, it can also be implemented in a group sending manner. All terminals can receive the grouping instruction, but only the terminal belonging to the temporary group writes the temporary group number to the group list to which it belongs, and the terminal that does not belong to the temporary group ignores the Group instructions. This approach compares wasted network resources and processing costs and is therefore not a preferred approach.

After the user scheduling task is completed, the request for releasing the task can be proposed through the visual interface, and then the public wireless network transmits a command to cancel the temporary group to the walkie-talkie, so that all the terminals of the temporary group can be restored to the original call group for daily patrol or Other routine tasks.

In this embodiment, the grouping instructions of the temporary group are transmitted through the mobile communication network (a public network such as GPRS, CDMA, GSM, and 3G functions), and then the cluster network makes a call to the terminal in the corresponding temporary group. In this way, the grouping instruction and the call instruction are sent by different networks, so that the number of terminals of the established temporary group is not limited by the signaling length. The grouping is very flexible and the scheduling efficiency is high, which can improve the ability of the emergency command department (such as the public security department) to respond quickly to emergency situations.

FIG. 2 is a schematic flow chart of a dynamic grouping method 200 according to another embodiment of the present invention. Reference map 1. Steps 201-202 are the same as steps 101-102 in the method 100, and are not described herein again.

In step 203, the client sends a trunking call command to the wireless dispatching station, and the wireless dispatching station initiates a group call of the temporary group and performs wireless communication with the terminal including the temporary group in the group list through the cluster network. The wireless dispatcher and the client can establish communication through a serial port or through a signaling channel. The call mode described herein is not intended to limit the present invention, and other ways in which the call can be made to the terminal are included in the scope of the present invention.

In another embodiment of the present invention, the grouping instructions generated by the master server may also be stored to a database. The database can be integrated into the master server or it can be set up separately.

In still another embodiment of the present invention, any communication or communication line (such as, but not limited to, TCP/IP (Transmission Control Protocol/Internet Protocol) link), any wired or The wireless link can be used to send the temporary group number in the grouping instruction generated by the master server to the system server of the cluster network for storage by the system server of the cluster network for future query and problem tracking, And avoid using other group groups with the same group number.

FIG. 3 is a schematic flow chart of a terminal uploading GPS (Global Positioning System) data according to an embodiment of the invention.

In step 301, the access server receives GPS data uploaded by the terminal through the mobile communication network and sends the GPS data to the main control server;

At step 302, the master server receives and transmits the GPS data to the client to display the location of the terminal on the client. The GPS data is stored and updated by the database.

Terminal uploading GPS information can be real-time or timed. In general, in order to save resources, it is relatively practical to select a timed upload.

4 is a block diagram showing the structure of a dynamic grouping system 400 in accordance with an embodiment of the present invention. As can be seen from FIG. 4, the dynamic grouping system 400 includes a master server 401 and an access server 402.

The master server 401 is configured to generate a grouping instruction according to the grouping request input by the client, and send the grouping instruction to the access server 402, where the grouping instruction includes a temporary group number and a final end corresponding to the temporary group number.

The access server 502 is configured to receive the grouping instruction and send the grouping instruction to the terminal 503 through the mobile communication network, so that the terminal 503 receiving the grouping instruction writes the temporary group group number into the group list to which it belongs .

The terminal 503 is configured to receive and parse the grouping instruction, and determine, according to the parsing result, whether to write the temporary group number in the grouping instruction into the group list to which it belongs.

The wireless dispatching station 504 is configured to receive a trunking call command sent by the master control server 501 through the signaling channel, thereby initiating a group call of the temporary group and performing wireless communication with the terminal 503 including the temporary group in the group list through the cluster network.

The master server 501 can group the terminals in advance and use a GIS (Geographic Information System) map to enable the user-installed visualization software to display the terminal on the client in an icon manner. For example, Shenzhen City will be divided into groups according to administrative areas such as Nanshan District, Futian District, Baoan District and Longgang District. For example, Terminal 1-10 belongs to Nanshan District and Terminal 11-30 belongs to Futian District. If a user (such as the Municipal Public Security Bureau) discovers a robbery incident in the residential area of Nanshan District, the temporary task can be performed by operating the interface of the installed visualization software: Nanshan District A is selected in the GIS map displayed on the visual scheduling interface. The icon of the terminal near the residential area, thus generating a grouping request, the terminal requesting the grouping is, for example, the terminal 8-10, and then selecting a number from the registered temporary grouping number, for example, the number 10000001, then a grouping instruction is generated. The grouping instruction includes a temporary group number 10000001 and a member of the temporary group number - terminal 8-10. The specific representation of the group number is not limited, and may be represented by, for example, an ASCII code (American Standard Code for Information Interchange). Of course, you can also choose other terminal display The manner in which the terminal displayed on the GIS map can be distinguished according to a certain rule is not limited to the present invention.

In order to enable a better positioning terminal, the terminal also needs to locate it by means of the positioning device in time or in real time and upload the GPS data to the access server 502 through the mobile communication network, and then the GPS data is sent by the access server 502 to The master server 501. After receiving the GPS data, the main control server 501 sends the GPS data to the client, so as to display the location of the terminal on the visual interface of the client, for example, displaying the GIS map, and acquiring each terminal in time by updating the GPS data uploaded by the terminal. The exact location.

Additionally, system 500 can also include a database for storing grouping instructions, as well as storing and updating GPS data uploaded by the terminal. The database can be integrated into the master server or it can be set up separately.

The dynamic grouping system 500 utilizes a mobile communication network (for example, GPRS (General Packet Radio Service), CDMA (Code Division Multiple Access), GSM (Global System for Mobile Communications, global mobile communication system, commonly known as "Global Pass"), 3G (3rd Generation Mobile Communication Technology) network, etc. Fast transmission and GPS positioning function of the walkie-talkie, transmitting GPS positioning data and dynamic grouping commands through the mobile communication network, realizing the dynamic grouping function of the cluster private network, Then, the trunking network is used to make a dispatch call.

It can be understood that the access server and the main control server can be integrated or set separately according to requirements, and the present invention does not limit this.

In addition, system 500 can also include a system server for receiving, by, for example, a TCP/IP link, the temporary group number of the server for self-control and saving for future queries and issue tracking, as well as avoiding the use of the same group number by other temporary groups.

The above detailed description of the system for dynamic grouping is equally applicable to the method of dynamic grouping. Similarly, a detailed description of the method of dynamic grouping is equally applicable to a system of dynamic grouping, which will not be described herein.
