Description

Method and device for processing POTS call of traditional telephone service

Technical Field

The present invention relates to the field of network communications, and in particular, to a method and apparatus for POTS call processing in a conventional telephone service.

Background

The traditional Telephone Service (POTS) is still a basic Telephone Service. POTS services mainly include: two-way voice path, dial tone, ringing signal, user dialing, etc. The ringing signal is sent to the terminal and is used for reminding the user of a prompt signal for calling; when the terminal is off-hook, the sending of the ringing signal is stopped, which is called ring-off.

With the development of semiconductor technology, the integration of boards is increasing, and POTS boards with different port numbers, such as 16 ports, 32 ports, 64 ports, etc., in a POTS system can provide POTS services with different user scales. When a POTS board receives multiple concurrent POTS calls at the same time, it will usually send a ringing signal to the corresponding ports of the concurrent POTS calls at the same time; if the ring-off happens to a plurality of ports at the same time, the impact current generated by the ring-off of each port is superposed, the instantaneous impact current exceeds the limit of the system power supply, the system is reset due to the power supply falling, the normal POTS service is influenced, and the usability of the system is deteriorated. If the number of the ports ringing simultaneously is limited by setting the upper limit of the ports ringing simultaneously, and if the number exceeds the upper limit, the system will refuse the new POTS call; thus, although the surge current at the time of ring-off can be controlled within an acceptable range to keep the system power supply stable at the time of ring-off, the call loss rate of the system increases, so that the usability of the system becomes poor.

Detailed Description

In a POTS system, a ringing signal has a ratio of on-off, a period with ringing is called off, a period without ringing is called off, a ringing period is the sum of on-off, and a ratio of on-off of the ringing signal is on: and (7) breaking. As shown in fig. 1, it is a diagram of the ring signal interruption ratio, where T1 is continuous, T2 is called off, one ring period is T1+ T2, and the interruption ratio is T1: T2. Different POTS systems may set different stutter ratios including, but not limited to, 1: 1, 1: 2, 1: 3, 1: 4, etc.

Referring to fig. 2, a flowchart of a method for processing a POTS call in a conventional telephone service according to an embodiment of the present invention is shown, where the method includes:

201: the network device divides a ringing period into N time sequences, wherein N is an integer value which is greater than or equal to 2.

The network device may divide the ringing period equally into N time sequences at regular intervals. Preferably, the time interval is the duration of the ringing period, and N is the quotient of the ringing period divided by the duration. For example, the ring signal has a 1: 4 on-off ratio, one ring period is 10 seconds, with 2 seconds on-off and 8 seconds off-off; the ringing period, i.e. 10 seconds, can be divided into 5 time sequences on average, i.e. 0 th, 2 nd, 4 th, 6 th, and 8 th seconds from the start time, according to the sequence, i.e. 2 seconds; the ringing period may be equally divided into 10 time sequences at 1 second intervals.

The network device may also divide the ring period into N time sequences at specific regular intervals. For example, the ringing signal has a 1: 4 ratio of on and off, and a ringing period of 10 seconds, with 2 seconds on and 8 seconds off. The ringing period, i.e., 10 seconds, may be divided into 4 time sequences, i.e., 0 th second, 1 st second, 3 rd second, and 7 th second, at time intervals that are incremented by multiples of 1 second.

202: a plurality of concurrent POTS calls are received.

A network device receives multiple concurrent POTS calls, which may be understood as multiple ports of the network device being called simultaneously.

One of ordinary skill in the art will appreciate that 201 may be performed before or after 202.

203: and dividing ports corresponding to the multiple concurrent POTS calls into M groups, wherein M is an integer value which is greater than or equal to 1 and less than or equal to N.

When the number of ports corresponding to the multiple concurrent POTS calls is less than N, M may be 1, or may be the number of ports corresponding to the multiple concurrent POTS calls; preferably, M is 1.

When the number of ports corresponding to the multiple concurrent POTS calls is greater than or equal to N, M is equal to N.

The number of ports of different ones of the M packets may be different.

204: assigning different ones of the M packets to different ones of the N timings.

The M packets may be sequentially assigned according to the N time sequences; the M packets may also be distributed in reverse order according to the N time sequences. For example, the ring cycle is divided into 3 time sequences, the ports are divided into 3 packets, and the 1 st to 3 rd packets can be sequentially allocated according to the 1 st to 3 rd time sequences, that is, the 1 st group is allocated at the 1 st time sequence, the 2 nd group is allocated at the 2 nd time sequence, and the 3 rd group is allocated at the 3 rd time sequence; the 1 st to 3 rd packets may be assigned in reverse order according to the 1 st to 3 rd time sequences, i.e., the 3 rd group is assigned at the 1 st time sequence, the 2 nd group is assigned at the 2 nd time sequence, and the 1 st group is assigned at the 3 rd time sequence.

205: and sending a ringing signal to the ports in the groups according to the time sequence of each group.

For example, the ring signal of the system has a 1: 3 on-off ratio, and a ring period of 8 seconds, with 2 seconds on-off and 6 seconds off-off. The system receives 58 POTS calls simultaneously and needs to send a ring signal to the corresponding port 1 to port 58. As shown in fig. 3, the ringing period is divided into 4 time sequences, and the 4 time sequences are 0 th second, 2 nd second, 4 th second and 6 th second, respectively. The 58 ports are divided into 4 groups, the first group being port 1 to port 15, the second group being port 16 to port 30, the third group being port 31 to port 44, and the fourth group being port 45 to port 58. Arranging 4 packets according to 4 time sequences, and sending a ringing signal according to the time sequence of the port, specifically: sending a ringing signal from the port 1 to the port 15 in 0 th second from the starting time; sending a ringing signal from port 16 to port 30 at 2 seconds from the start time; sending a ringing signal to the terminal from the port 31 to the port 44 in the 4 th second from the starting time; the ringing signal is sent to the terminal from port 45 to port 58 for the 6 th second from the start time.

By adopting the technical scheme provided by the embodiment of the invention, the ringing period of the system is divided into N time sequences, the ports corresponding to a plurality of concurrent POTS calls are divided into M groups, and the ringing signals are sent according to the group time-sharing sequence, so that the total impact current of the system generated by ring-cutting can be reduced to one M of the original total impact current, the stability of a system power supply is improved, and the number of the concurrent POTS calls does not need to be limited; thus, the problem of poor usability of the POTS system when a large number of concurrent POTS calls are received in the prior art can be solved.

The transmitter 405 is specifically configured to send a ring signal to the ports according to the time sequence of the ports of each packet allocated by the allocation module.

For example, the ring signal of the system has a 1: 3 on-off ratio, and a ring period of 8 seconds, with 2 seconds on-off and 6 seconds off-off. The time sequence dividing module 401 equally divides the ringing period into 4 time sequences, where the 4 time sequences are the 0 th, 2 nd, 4 th and 6 th seconds of the start, respectively.
