[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] It should be understood that the terms "first", "second", "third", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, for example, they can be implemented according to an order other than those given in the diagrams or descriptions of the embodiments of this application.

[0045] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0046] The term "module" as used in this application refers to any known or later developed hardware, software, firmware, artificial intelligence, fuzzy logic, or combination of hardware and / or software code that is capable of performing the functions associated with that element.

[0047] As an important part of the command and dispatch system of various industries, wireless cluster communication has become an indispensable means of communication for collaborative operations, disaster relief and major security activities. For example, the Tetra wireless cluster communication system generally has a dispatch desk set up for the Tetra wireless cluster communication system during user use. The dispatch desk can control the vehicle station to initiate calls to other terminal users. For example, it includes single call service and group call service. The single call service is mainly a point-to-point call between Tetra digital cluster terminals, that is, a voice intercom between one user and another user. The group call service is a call between a single user and a group of users. When performing the group call service, it is necessary to first determine the identification numbers of the group members to connect these groups. Members are added to the group. For some important groups, a corresponding radio will be configured. When a user initiates a speech, the radio will initiate a group call to other members in the group or receive group calls initiated by other members. This configuration method is relatively fixed, so most users can only listen to the current resident group and the main speaker on the Tetra side of the corresponding current resident group during use. In addition, due to the limitation of the number of radios, it is difficult to equip each group with a radio. When the user needs to initiate other group calls, the user needs to manually operate the radio to reconfigure. During wireless communication, some users are not convenient to manually operate the radio due to distance limitations, resulting in the inability to flexibly initiate group calls and inconvenient dynamic scheduling.

[0048] In response to the above problems, an embodiment of the present application provides a group call docking system and method, in which a terminal initiates a group call request to a core network device, and the core network device forwards it to a broadband side device to switch the vehicle station to the group that the user wants to call, so that the user can flexibly make group calls. At the same time, the broadband side device can also initiate a group call to the narrowband side terminal through the broadband side intercom terminal, thereby realizing a two-way group call. Each group call member can initiate group speaking and listening.

[0049] Figure 1 A structural diagram of a first embodiment of a group call docking system provided in an embodiment of the present application, such as Figure 1 As shown, the group call docking system includes a terminal 11, a core network device 12, a broadband side device 13 and a vehicle station 14.

[0050] Among them, the terminal 11 is used to send a designated group call request to the core network device 12 through the first air interface, the core network device 12 is used to forward the designated group call request to the broadband side device 13 through the first ground interface, and the broadband side device 13 is used to switch the vehicle 14 to the designated group according to the designated group call request. When the broadband device 13 obtains the broadband side group call request, it can initiate a group call to the terminal 11 through the core network device 12 according to the broadband side group call request.

[0051] Among them, the designated group includes group members who can make group calls to each other. The designated group call request includes a group call number and terminal initiation information. In this embodiment, the terminal 11 can be a handheld intercom terminal or a car intercom terminal. Each terminal is configured with a number for easy distinction and identification. The group call number is the number of other group members, and the terminal initiation information is the initiator information, such as the initiator's number.

[0052] Exemplarily, when the user of the terminal 11 needs to initiate a group call, a designated group call will be initiated according to the Tetra air interface requirements, that is, a designated group call request is sent to the core network device 12 through the first air interface.

[0053] In the embodiment of the present application, the terminal 11 and the core network device 12 both belong to the Tetra wireless cluster communication system. The user can use the terminal 11 to listen to the speeches of the members of the group or initiate / press a button to speak. For example, the user can use the terminal 11 to listen to the speeches of other terminals in the Tetra cluster communication system or speak to other terminals.

[0054] Exemplarily, the Tetra cluster communication system may include multiple terminals 11, and each terminal 11 may initiate a group call. When multiple terminals 11 are in the same group, they may monitor each other or initiate calls to other members.

[0055] It is worth noting that in the embodiment of the present application, the Tetra cluster communication system belongs to a narrowband wireless communication system, which can transmit services such as voice or telephone. In contrast, the broadband side device 13 belongs to a wired broadband communication system, which has a higher transmission bandwidth than the narrowband wireless communication system and can transmit services such as video.

[0056] In an embodiment of the present application, the broadband side device 13 may include a dispatching station. When the core network device 12 forwards the designated group call request to the broadband side device 13 through the first ground interface, the broadband side device 13 will switch the vehicle station 14 so that the vehicle station 14 switches to the designated group. When the vehicle station 14 switches to the designated group, group members can monitor each other or initiate speeches.

[0057] Exemplarily, the group call request group can be a group specified by terminal 11. For example, if user D wants to talk and listen to user A, user B and user C, terminal 11 can send user A's number, user B's number and user C's number to core network device 12 and forward it to broadband side device 13. Then broadband side device 13 switches the vehicle station 14 to the group of user A, user B, user C and user D. At this time, user A, user B, user C and user D, as group members, can listen to each other's speech or initiate speech.

[0058] Exemplarily, the broadband side device 13 may also have a broadband side intercom terminal, and the user of the broadband side intercom terminal may also initiate a broadband side group call request, which includes the number information of the terminal that the user wants to make a group call to, and then initiates the group call in the core network device 12 through the vehicle station corresponding to the wireless docking channel, so that the user of the broadband side intercom terminal can make a group call to the user of the terminal 11.

[0059] Figure 2 A schematic diagram of the structure of the core network device provided in the embodiment of the present application, such as Figure 2 As shown, it includes a ground network and an air network. The terminal can initiate a designated group call request to the air network of the core network device through the air interface, and then the ground network of the core network device forwards the designated group call request to the broadband side device through the ground interface.

[0060] Figure 3 A structural diagram of Embodiment 2 of the group call docking system provided in the embodiment of the present application, such as Figure 3 As shown, the terminal 31 may be a handheld terminal, which communicates with the eCNS core network in the Tetra private network 32 through a base station.

[0061] The terminal 31 can initiate a designated group call request to call the designated group members, and then the Ecns core network forwards the designated group call request to the second server 33 through the ground interface. The second server 33 extracts the group call number and initiator information from the designated group call request, and forwards it to the monitoring gateway 34 through the SOCKET interface. After the monitoring gateway 34 monitors that a group call is initiated, it forwards the designated group call request to the intranet controller 35. After the intranet controller 35 analyzes and confirms the number, it forwards it to the private network controller 37 through the security access platform 36. The private network controller 37 will allocate corresponding channel resources, select a suitable wireless docking channel based on information such as area and priority, and then send the designated group call request to the docking gateway 38 where the wireless docking channel is located. The docking gateway 38 switches the wireless docking to the designated group through the corresponding vehicle station. After the vehicle station switches to the designated group, the group members can monitor or talk to each other.

[0062] At the same time, the broadband side device can also initiate a broadband side group call through the broadband side intercom terminal, and then confirm the group call number in the broadband group call request through the private network controller 37, and allocate a suitable docking channel according to information such as area and priority, and then send the broadband group call request to the docking gateway 38 corresponding to the docking channel, so that the vehicle station corresponding to the docking channel directly initiates a group call at the air interface of the TETRA private network to call the terminal 31 and realize the group call.

[0063] Exemplarily, the group call docking system also includes a server, which is a second-open server 33, wherein the second-open server 33 is used to obtain a designated group call request sent by the eCNS core network through the first ground interface, and extract the group call number and terminal initiation information in the designated group call request, and forward it to the monitoring gateway 34 in the broadband side device.

[0064] In the embodiment of the present application, the second server 33 can be an intranet server. When performing wireless communication services, transmitting a designated group call request through the intranet server can effectively ensure information security, and the intranet is convenient for installation and maintenance, and can achieve rapid deployment.

[0065] Exemplarily, when wireless cluster communication is used in the public security industry, the second server may be a public security intranet server, and the second server may implement forwarding of group call numbers and terminal-initiated information through a socket interface.

[0066] Exemplarily, based on the above embodiment, the broadband side device includes: an intranet device and a private network connection device.

[0067] The intranet device is used to obtain the group call number and terminal initiation information from the server through the socket interface and forward it to the private network docking device.

[0068] In the embodiment of the present application, the secondary server 33 can send the group call number to the intranet device, and the intranet device can make a group call notification and initiate a group call when receiving the group call number and the terminal initiation information.

[0069] Exemplarily, intranet devices may be set up in a public security intranet to ensure information security.

[0070] The private network docking equipment is used to switch the vehicle station to the specified group according to the group call number and the terminal initiation information.

[0071] In an embodiment of the present application, when the terminal initiates a group call request to make a group call with designated group members, the private network docking device can first confirm whether the group call has been initiated. If it has been initiated, the designated group call request of the user will be directly terminated. If it has not been initiated, the vehicle station will be switched to the designated group, which includes the group members that the user needs to call, and group members can initiate group calls with each other.

[0072] Exemplarily, based on the above embodiment, the intranet device includes: a monitoring gateway and an intranet controller, wherein the monitoring gateway is used to monitor the group call number and terminal initiation information obtained through the socket interface, and forward the group call number and terminal initiation information to the intranet controller.

[0073] In an embodiment of the present application, the monitoring gateway can obtain the group call number and the terminal initiation information from the server through the socket interface, and the monitoring gateway can package the group call number and the terminal initiation information and forward them to the intranet controller.

[0074] For example, when wireless trunking communication is used in the public security industry, the monitoring gateway 34 can be set in the public security intranet.

[0075] The intranet controller is used to analyze and confirm the number information and terminal initiation information and forward the number information and terminal initiation information to the private network docking device.

[0076] In the embodiment of the present application, after the intranet controller receives the number information and the terminal initiation information, it can send a group call initiation message to the private network docking device to notify the private network docking device that there is a group call initiation request.

[0077] Exemplarily, based on the above embodiment, the private network docking device includes: a group belonging controller and a docking gateway. The group belonging controller is used to obtain area information and priority information, determine the corresponding wireless docking channel, and send number information and terminal initiation information to the docking gateway of the wireless docking channel.

[0078] In an embodiment of the present application, the group belonging controller needs to determine the corresponding wireless docking channel based on the area information and priority information. The area information refers to the user's belonging area and the user's belonging area corresponding to the number information. The priority information indicates the priority of the user initiating the designated group call request. The belonging area and priority can be pre-set according to actual conditions.

[0079] For example, for major call transactions such as fire call transactions or emergency call transactions, the priority of the corresponding designated group call request is relatively high. At this time, the wireless docking channel can be determined first or a dedicated wireless docking channel can be used to send number information and terminal initiation information to the docking gateway.

[0080] Exemplarily, the group home controller may also send a group call initiation request to notify the docking gateway.

[0081] The docking gateway is used to switch the vehicle station corresponding to the wireless docking channel to the specified group according to the number information and terminal initiation information.

[0082] In an embodiment of the present application, the designated group includes corresponding group members. When the vehicle station switches to the designated group, the group members can monitor or talk to each other. The determination of the group members is achieved based on the number information and the terminal initiation information.

[0083] Exemplarily, when the number information includes the numbers of user A, user B and user C, and the terminal initiation information includes the number of the group call initiating user, the group members include user A, user B, user C and the group initiating user.

[0084] In an embodiment of the present application, a wireless docking channel can establish a preset corresponding relationship with the vehicle station.

[0085] Exemplarily, in one embodiment, when the vehicle station switches to a designated group, the docking gateway may output a broadband group call docking confirmation to the group home controller.

[0086] In the embodiment of the present application, the docking gateway outputs a broadband group call docking confirmation to the group home controller to complete the closed loop of the entire group call docking process and notify the group home controller to complete the vehicle station switching.

[0087] Exemplarily, the docking gateway may also output broadband group call docking failure information to the group home controller, notifying the group home controller of the vehicle station switching failure.

[0088] Exemplarily, in one embodiment, when the vehicle station is switched to a designated group, it waits to be pulled into the group call request group through a delayed entry method.

[0089] Exemplarily, based on the above embodiment, the broadband side device further includes a broadband side intercom terminal. The broadband side intercom terminal is used to send a broadband group call request, and the broadband group call request includes the number of the terminal making the group call.

[0090] In an embodiment of the present application, the broadband side device can also make a group call through the broadband side intercom terminal to call users in the Tetra cluster communication system. For example, the broadband group call request includes information about group members such as the numbers of group members.

[0091] The private network docking device is also used to send the group call to the core network device through the second air interface according to the broadband group call request, and the core network device is also used to send the group call to the corresponding terminal through the second ground interface to make a call.

[0092] Among them, the group call is used to call the terminals of the group members. In the embodiment of the present application, the second air interface can be an interface in the core network device.

[0093] In an embodiment of the present application, the terminals may include handheld terminals and vehicle-mounted terminals. For example, when the broadband group call request includes the numbers of group members, the core network device will directly initiate calls to the terminals corresponding to these numbers, thereby enabling the broadband side to call users in the Tetra cluster communication system.

[0094] Exemplarily, based on the above embodiment, the broadband side device further includes a router, and the router is used to obtain the broadband group call request sent by the broadband side intercom terminal and forward it to the group home controller.

[0095] In the embodiment of the present application, the broadband side intercom terminal may be a handheld terminal, and the broadband group call request sent by the broadband side intercom terminal may be routed to the group home controller through a router.

[0096] The group home controller is further used to determine a corresponding docking channel according to the broadband group call request, and send the broadband group call request to a docking gateway of the docking channel.

[0097] In an embodiment of the present application, the broadband group call request may include regional information and priority information, etc. The group belonging controller can select a suitable docking channel based on the regional information and priority information contained in the broadband group call request, and then send the group call message to the docking gateway of the docking channel.

[0098] The docking gateway 38 is also used to send the group call message to the vehicle station corresponding to the docking channel, and the vehicle station sends the group call to the core network device through the second air interface according to the group members included in the broadband group call request to make a group call to the terminals of the group members.

[0099] In an embodiment of the present application, the vehicle station obtains the group members in the broadband group call request, and then communicates with the core network device through the second air interface, and the ground interface of the core network device calls the group members.

[0100] In summary, the group call docking system provided in the embodiment of the present application is that the terminal can send a designated group call request to the core network device through the air interface, and then the ground interface of the core network device forwards the group call request to the broadband side device to switch the vehicle station to the designated group, which is convenient for users to quickly complete the group call and improve the dynamic scheduling efficiency. At the same time, the broadband side intercom terminal of the broadband side device can also make a group call to the terminal to realize a two-way call.

[0101] Exemplarily, based on the above embodiments, Figure 4 A flow chart of a group call connection initiated by a speaker of a TETRA network provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, it may specifically include the following steps:

[0102] (1) The terminal 41 of the TETRA network (including handheld and vehicle-mounted terminals) initiates a designated group call according to the TETRA air interface requirements;

[0103] (2) The eCNS core network of the TETRA network 42 forwards the group call request to the secondary server 43 via the ground interface;

[0104] (3) The secondary server 43 extracts the group call number and the initiator information from the group call request and forwards it to the monitoring gateway 44 of the broadband side device through the SOCKET interface;

[0105] (4) The monitoring gateway 44 sends the group call message initiated by the TETRA network to the intranet controller 45;

[0106] (5) The intranet controller 45 analyzes the number information in the group call request and forwards the group call initiation message to the group home controller of the private network, i.e., the private network controller 47, through the secure access platform 46;

[0107] (6) The private network controller 47 allocates corresponding channel resources. First, the private network controller 47 needs to determine whether the corresponding group call has been initiated. If it has been initiated, the request is terminated. If it has not been initiated, a suitable wireless connection channel is selected based on the area and priority.

[0108] (7) The private network controller 47 sends the group call initiation point-to-point to the docking gateway 48 where the wireless docking channel is located;

[0109] (8) The docking gateway 48 switches the TETRA vehicle station corresponding to the wireless docking channel to the corresponding group, i.e., the designated group, and the vehicle station enters the delayed entry mode to be pulled into the group call.

[0110] (9) After the vehicle-to-vehicle group call is initiated, the docking gateway 48 initiates a broadband group call initiation confirmation, closing the loop of this group call docking.

[0111] Exemplarily, based on the above embodiments, Figure 5 A flow chart of a group call connection initiated by a speaker of a broadband side device provided in an embodiment of the present application is shown in FIG. Figure 5 As shown, it may specifically include the following steps:

[0112] (S1) When the broadband-side intercom terminal of the broadband-side device initiates a broadband-side group call, it will be routed to the group-attributing controller, i.e., the private network controller 51;

[0113] (S2) The private network controller 51 confirms the corresponding TETRA group call number and allocates a suitable connection channel based on the area and priority;

[0114] (S3) the private network controller 51 sends the broadband group call point-to-point to the docking gateway 52 corresponding to the designated channel;

[0115] (S4) the docking gateway 52 directly initiates a group call on the air interface of the TETRA private network 53 for the TETRA vehicle station corresponding to the docking channel according to the group in the broadband side group call message;

[0116] (S5) The TETRA private network 53 sends the call initiation to other member devices 54 in the group according to the group configuration of the broadband side group call, thereby implementing the group call.

[0117] The above embodiments have described in detail the group call docking system provided in the embodiments of the present application. The group call docking method of the group call docking system is explained below. For the parts not mentioned in the embodiments of the method, reference can be made to the records of the above embodiments.

[0118] Figure 6 A flow chart of a group call docking method provided in an embodiment of the present application is shown in FIG. Figure 6 As shown, the method includes:

[0119] S601. A terminal sends a designated group call request to a core network device via a first air interface.

[0120] Among them, the designated group call request includes the group call number and the terminal initiation information. In the embodiment of the present application, the core network device includes multiple air interfaces and ground interfaces. The terminal can be a handheld terminal or a vehicle-mounted terminal. The designated group call request represents the intercom terminal to which the user needs to request a group call.

[0121] For example, when a user needs to call user A, user B, and user C, a designated group call request needs to be initiated to request to call user A, user B, and user C.

[0122] S602. The core network device forwards the designated group call request to the broadband side device through the first ground interface.

[0123] In the embodiment of the present application, the core network equipment and the terminal both belong to the Tetra trunking communication system. Exemplarily, the core network equipment includes a TETRA private network.

[0124] S603: The broadband side device switches the vehicle station to the designated group according to the group call number and the terminal initiation information.

[0125] The designated group includes group members who can make group calls to each other.

[0126] In the embodiment of the present application, after the vehicle station switches to the designated group, the user can call the group members in the designated group, and the members in the group can also monitor and initiate intercom.

[0127] Exemplarily, the group call number includes the number of user A, the number of user B and the number of user C, and the group members in the group call request group include user A, user B and user C.

[0128] S604, when the broadband side device obtains the broadband side group call request, it initiates the broadband side group call request to the vehicle station;

[0129] S605, the vehicle station initiates a group call to the core network via the second air interface;
