Definitions
- the present invention relates to wireless communication technologies, and in particular, to a method for implementing conference call and dynamic grouping based on a walkie-talkie. Background technique
- the dispatching station exists only in the trunking communication system and is responsible for functions such as scheduling, grouping, calling, and monitoring. At the same time, the dispatching station relies on the presence of the base station, and uses the internal database of the base station to transmit various signals to the corresponding receiving device through the radio frequency module of the base station.
- the mobile station has been in a relatively passive state during the scheduling and function assignment process, that is, it is controlled by the dispatching station and the network management system. In the traditional application, the mobile station can only perform functions such as calling and information transmission. For calls, there are currently only two major types of calls:
- One is a single call, that is, one mobile station calls another mobile station, and communication occurs between two mobile stations (as shown in Figure 1).
- the second is the group call.
- a single mobile station calls a fixed group of users. This group of users has been determined (as shown in Figure 2).
- the group call here is fixed in advance, and there are two processes for specifying the group.
- One is to write the frequency to the mobile station (for example, the walkie-talkie) (the frequency is to change the frequency corresponding to the channel of the mobile terminal) Timing, defining this walkie-talkie can make calls to those groups and respond to calls from users in this group.
- Another relatively new application is to dynamically group in the dispatcher or network management terminal, and modify the internal settings of the walkie-talkie through the air interface of the base station, similar to another write frequency.
- FIG. 3 is a schematic diagram of a conventional dispatching station.
- a conventional dispatching station is based on a base station.
- the general dispatching station software is installed on a PC, and the PC is connected to the base station through a serial port or an IP network, and uses the base station.
- the transmitting and receiving devices transmit signals to affect the remaining mobile stations or base stations.
- the mobile dispatcher since the console software is installed on the PC, the mobile dispatcher does not Convenient, and the dispatching station depends on the existence of the base station; if it is not a trunking communication system, or each mobile station is in the pass-through mode, the scheduling function cannot be provided.
- this application mode is defined as a conference call mode
- the conference call mode is currently only available in wired telephones, and has not been involved in mobile communications, so it is necessary to extend it to applications in mobile communications, especially in private network communications.

- N the number of transmissions
- the receiving end receives the control packet
- the writing frequency module is started, and the packet number is deleted from the grouping list. If, for some reason, a receiver cannot receive the disbanded control packet, the receiver will automatically release the group after a period of activity that has not been associated with the group.
- the above method for implementing a conference call based on a walkie-talkie may be based on a specific protocol, such as a digital mobile radio (DMR) protocol stack based on a walkie-talkie.
- DMR digital mobile radio
- a general protocol provides an extensible interface, so the extensible interface of the protocol can be considered when designing the protocol stack, and then the human interface module can be used to implement the dynamic grouping of the present invention.
- the method for implementing the walkie-talkie-based conference implementation of the present invention will be described in detail below by using a preset protocol stack as a DMR protocol stack.
- each control frame data packet of the DMR includes a payload, a slot type, and a synchronization pattern, wherein the slot type includes color code, data type, and forward error correction parity redundancy.
- the data type part includes various possible values in the following table: Table 2 Definition of Data Type Information element length value meaning
- 1111 2 Reserved for future expansion As can be seen from Table 2, from 1010 2 to 1111 2 are all prepared for expansion. Specifically, during the implementation process, 1011 2 can be set as a temporary conference call initiated by the mobile terminal, defined as: DG By MS.

- the Group Voice Channel User LC PDU used when initiating the group call is as follows: Table 3 Group Call Control PDU
- the present invention utilizes the extensible interface of the protocol to design a PDU to carry the information that the sender needs to send, including three necessary elements: the ID of the sender, the group ID of the group, and the temporary conference. The group ID of the call.
- an authentication code can also be included.
- some algorithms may be embedded in each mobile terminal, and the identity verification code is closed with the sender address and the receiver address to perform encryption.
- the PDU designed by the present invention is specifically as follows:
- Table 4 is grouped according to the mobile terminal control packet
- the DMR protocol stack is divided into three layers, the call control layer (CCL), the data link layer (DLL), and the physical layer (PL).
- CCL call control layer
- DLL data link layer
- PL physical layer
- the processing on the receiving end is relatively simple, and will not be described here.
- the method for implementing a call conference based on the walkie-talkie according to the present invention can be used in any mode of private network communication, that is, it can be used in the through mode, or in the transit mode and the cluster mode. It is conducive to expanding the application mode of private network communication, which is beneficial for manufacturers to increase product selling points, occupying advantages in competition, and saving time and handling problems quickly and easily in emergencies.

- the specific parameters are as follows: Table 6 sets the number of the terminal
- the group ID of the dynamic grouping for example, the group ID of the dynamic grouping can be 10005;
- the ID of the sender, the group ID of the group, and the group ID of the dynamic group are written into the preset protocol stack module, and are generated according to the encoding format and the extensible interface inherent in the preset protocol stack module. Control package.
- the transmitting end A periodically transmits the control packet (for example, every 3 minutes), so that the late mobile terminal can join the new group.
- a traditional group call can be made to the mobile terminal that has joined the group.
- control frame sent by the sender to the receiver can be encrypted and embedded with an encryption algorithm, which can better ensure the security of the data during transmission.
- the call can be made, and the various calls made at this time will be the same as the normal group call.
- a release step (shown in Figure 16) is also included.
- PDU Dissolution Control Packet
- N the number of transmissions
- the receiving end receives the control packet
- the writing frequency module is started, and the packet number is deleted from the grouping list.
- two ways of dissolving the control packet can be set. One is to send a de-packeted PDU immediately after the group is used. At this time, the PDU is also transmitted 3 times (interval is 3 minutes) to avoid the communication distance. The walkie-talkie did not receive the signal for some reason.
- the other is to automatically delete the group number of the dynamic group without activity after the predetermined time (for example, 30 minutes), which is to prevent some mobile terminals from receiving the disbanded signal. Delete this group number to avoid excessive memory usage after multiple operations.
- the method for implementing dynamic grouping based on the walkie-talkie in the present invention can use the scheduling function by the mobile station in the direct mode, and the usage mode is more changed; the user can purchase and use the base station for the scheduling function, which can be large. Amplitude savings; use mobile-based scheduling system, convenient and flexible, easy to control; especially for emergencies, save time and quickly and easily handle problems.
