Problems solved by technology

However, due to the use of one-way single-circuit connection, once the circuit is disconnected or fails, the call cannot be carried out normally, resulting in poor call reliability and lower user experience satisfaction

Embodiment 1

[0033] See figure 1 , the call service implementation method provided in this example specifically includes:

[0034] After detecting that the calling terminal is off-hook, the calling side end office allocates the calling subscriber circuit to the calling terminal;

[0035] The calling side end office receives the call request sent by the calling terminal, establishes a main call circuit to the called side end office according to the received call request, and initiates a main outgoing call to the called side end office;

[0036] After receiving the main outgoing call, the called terminal office allocates a called subscriber circuit for the corresponding called terminal, and feeds back a ringback response to the calling side end office;

[0037] The called end office detects that the called terminal is off-hook, and sends a call message to the calling end office;

[0038] After receiving the call message, the calling side end office establishes a backup call circuit to the ...

Embodiment 2

[0061] In order to better understand the present invention, the present invention will be further described below in conjunction with a complete call flow.

[0062] In this example, for the convenience of expression and understanding, for the calling side, define the main call circuit as the main outgoing call circuit, and the backup call circuit as the backup outgoing call circuit; for the called side, define the main call circuit as the main The call circuit is a standby incoming call circuit; in this example, the information between the calling service processing module and the called service processing module is selected to be processed through the NO.7 / NO. signaling processing module, wherein, NO.7 signaling processing The module refers to the No.7 signaling software module, and the No.1 information processing module refers to the No.1 Suilu China No.1 software module, collectively referred to as the No.7 / No.1 information processing module. Below, the present invention wi...

Abstract

The invention discloses an implement method and a system for call services. A call is conducted through a way that one way rings and double ways are consecutive in a sound mixing mode in a call implement method. An existing consecutive method with a one-way single circuit is changed, so that in the calling process, when one way of a calling circuit breaks over or is disconnected, the other way of a calling circuit still can work normally. Therefore, normal operation of the call can be ensured, and the call can be affected only when all built call circuits break over or are disconnected. In addition, when one way of the calling circuit is interfered, the other way of the calling circuit still can work normally, and accordingly capacity of anti-interference can be improved, and quality of the call is ensured. Through the implement method, reliability of normal operation of the call services is improved, the quality of the call is ensured, and accordingly a degree of satisfaction of user experience is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a calling service realization method and a calling service system. Background technique [0002] Compared with wireless and VOIP (Voice over Internet Protocol) calls, PSTN (Public Switched Telephone Network) telephones have superior performance such as high connection rate and fixed short delay characteristics, and their applications are increasingly widespread. Facing private networks, military networks The high reliability requirements of high-end users such as high-end users, the national standard for trunk call loss is 3 / 10,000, which cannot meet the high call completion rate and high reliability requirements of such high-end users. Obviously, wireless and VOIP are more difficult to meet the requirements of high-end users in this respect. [0003] In the current PSTN circuit switching to realize the call service process, the caller and the called party are connected in one-way and ...
