Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a service message transmission method and equipment.
Background
Broadband Trunking Communication (B-TrunC) is a dedicated broadband Trunking system protocol standard for "LTE digital transmission + Trunking voice Communication" in Time Division Long Term Evolution (TD-LTE) specified by the broadband Trunking industry alliance, and the protocol mainly specifies broadband Trunking service functions such as Trunking voice, Trunking video, and media Trunking scheduling, has the characteristics of flexible bandwidth, high spectral efficiency, low Time delay, and high reliability, and can meet the requirements of professional users on voice Trunking, broadband data, emergency command scheduling, and the like. Before the introduction of B-TrunC systems, customers may have deployed corresponding narrowband cluster systems, such as Police Digital Trunking (PDT) systems, which are widely used in the public security industry. To reduce costs, it is desirable to configure the B-TrunC system to securely interconnect with existing PDT systems. Especially, end-to-end data encryption and decryption in the B-Trunc system and the PDT system are important.
The encryption card used in the PDT system needs to obtain call information such as "number of main speaker, group number" and the like (ems (Embedded signaling) when the encryption card is transmitted together with voice, and individual transmission is called lch (link Control header)) and "encryption related information" (eems (encrypted Embedded signaling) when the encryption card is transmitted together with voice, and individual transmission is called PI). After the receiving end of the group obtains the information, the receiving end can decrypt the voice data by using the encryption card.
However, in the PDT system, because of the problem of air interface bandwidth, a call message "number of a main speaker, group number" or "encryption related information" is carried alternately every 360ms, that is, 720ms is required to obtain complete information for decryption, the delay is large, and if the terminal is delayed, the time for monitoring the group later is also affected. And the broadband system B-Trunc is not limited by the system bandwidth, and the user perception is better. Therefore, when the bandwidth and the narrow bandwidth are communicated, the receiving end in the B-TrunC system can only receive the complete number of the main speaking end, the group number or the encryption related information for 720ms, and cannot decrypt the voice data in time, which causes a large delay when the receiving end in the B-TrunC system receives the voice data of the narrow bandwidth trunking system, and affects the user experience.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all embodiments of the present invention. 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.
Fig. 1 is a schematic structural diagram of a cluster system according to an embodiment of the present invention. As shown in fig. 1, the cluster system provided in this embodiment includes a narrowband cluster system 100, a B-TrunC system 200, and a gateway device 300 responsible for data transmission of the narrowband cluster system 100 and the B-TrunC system 200. The narrowband trunking system 100 has a plurality of terminal apparatuses 101, and the B-TrunC system 200 also has a plurality of terminal apparatuses 102. When the terminal device 101 communicates with the terminal device 102, the initiator is a master, and the receiver is a receiver, that is, the terminal device 101 may be either a master or a receiver, and similarly, the terminal device 102 may be either a master or a receiver. The terminal device 101 and the terminal device 102 may be a child story machine, a mobile phone, a tablet, a vehicle-mounted terminal, or the like. The implementation manner of the terminal is not particularly limited in this embodiment, as long as the terminal device can perform service packet transmission.
The network Transport Protocol (RTP) provides an end-to-end delivery service with Real-time features for data, such as interactive video and audio or analog data under multicast or unicast network services.
The narrowband cluster system may be a Police Digital Trunking (PDT).
At present, in the B-TrunC system, a "number and group number of a main talker" or "encryption related information" is carried every 60ms, that is, a receiving end in the 120ms B-TrunC system is required to receive the complete "number and group number of the main talker" or "encryption related information" and perform voice data decryption. However, in the PDT system, because of the problem of air interface bandwidth, a "number and group number of a main speaker" or "encryption related information" is carried alternately every 360ms, when the wide and narrow bands are intercommunicated, a receiving end in the 720ms B-TrunC system is required to receive the complete "number and group number of the main speaker" or "encryption related information", and cannot decrypt the voice data in time, which causes a large delay to the receiving end in the B-TrunC system to receive the voice data, and affects the user experience. In order to solve the technical problem, this embodiment provides a service packet transmission method, which can decrypt, in time, the voice data sent by the PDT system and received by the receiving end in the B-TrunC system, reduce the internal delay of the receiving end in the B-TrunC system for processing the voice data sent by the PDT system, and improve user experience. The following examples are given for the purpose of illustration.

In this embodiment, before the master in the narrowband trunking system sends the service packet, the network transport protocol RTP packet is first sent to the gateway device, and then sent by the gateway device to the receiving ends of other broadband systems in the group, so as to establish the communication connection between the master and the receiving ends.
Specifically, the RTP packet includes a plurality of RTP packets. The RTP message alternately carries the relevant identification and encryption relevant information of the main speaking end in the narrow-band cluster system.

In this embodiment, the gateway device has a processor and a memory, and the memory is used for storing data.
Specifically, the correspondence between the relevant identifier of the master speaker in the narrowband cluster system and the relevant encryption information may be stored in a database or a preset table of a memory.

Specifically, one or more receiving terminals in the B-TrunC system may be determined by the group identifier, and the first service packet is sent to the one or more receiving terminals in the B-TrunC system.
In this embodiment, an interval period for the B-TrunC system to send or receive a packet (RTP packet or service packet) may be a second preset duration. Wherein the second preset duration of the inter-period of the B-TrunC system is 60ms (milliseconds).
For example, when the interval period of the B-TrunC system is 60ms, after the interval period (120ms) of two B-TrunC systems, one or more receiving terminals in the B-TrunC system can receive the relevant identification and encryption relevant information of the main speaking terminal in the complete narrowband trunking system, and can process the voice data in time (e.g., parse and play the voice data).

According to the embodiment, the related identification and the encryption related information of the main speaking end in the narrow-band cluster system can be sent to the receiving end in the B-trunC system according to the interval period of the B-trunC system, and after the interval period of the two B-trunC systems, the receiving end in the B-trunC system can receive the related identification and the encryption related information of the main speaking end in the complete narrow-band cluster system, so that the time delay of the receiving end in the B-trunC system for receiving the voice data in the narrow-band cluster system is reduced, and the user experience is improved.
