Public network talkback equipment, heartbeat processing method of public network talkback equipment and medium

Abstract

The invention discloses a heartbeat processing method for public network interphone equipment. The method specifically comprises the following steps that the initial state is set to be 0, Tc, Ta, m1,m2, n1 and n2 are set, Tc is the periodic sending period of heartbeat packets in a quiescent period, Ta is a basic threshold value, m1 and m2 are threshold value adjusting parameters, and n1 and n2 are periodic adjusting parameters; When one-time communication of the public network talkback device is finished, the timer starts timing; Comparing the timing of the timer with Ta, m1 * Ta and m2 * Tarespectively to obtain a comparison result, and sending heartbeat packets to the system end by the hand according to the comparison result in different periods; And when the timer is greater than thesleep period defined in the 3GPP protocol, the hand station stops sending the heartbeat packet to the system end. Different heartbeat packet sending periods are set according to different silence durations, so that the voice service is ensured, and meanwhile, the cruising ability of the public network talkback equipment is improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication methods, in particular to a public network intercom device, a heartbeat processing method and a medium for the public network intercom device. Background technique [0002] 4G wireless network technology no longer distinguishes between circuit domain and packet domain services, and the technology of VOIP (voice over IP) will become the mainstream. However, the biggest technical difficulty in adopting the IP method is how to guarantee QoS (Quality of Service), especially the time delay. [0003] The POC (POC, Push to talk Over Cell) public network walkie-talkie running on the 4G network also uses IP to carry voice, because the carrier is a data channel and lacks QoS guarantee for real-time voice services, resulting in unsuitable control of delay. [0004] In order to solve this problem, the industry generally adopts the method that, in order to maintain the link connection with the ...

Problems solved by technology

However, the method of sending heartbeat small packets at high frequency will quickly exhaust the power of the mobile station. In addition, sending frequent small packets regularly will also increase the load on the transmission network.

In order to reduce the frequency of sending packets, you can also use the method of increasing the data storage buffer, but this method will increase the service delay and affect the user's service experience
