Problems solved by technology

[0018] The present invention is proposed for the problem that the selection means of the number analyzer for analyzing the called number is relatively simple, and the forward office cannot participate in the number analysis process of the softswitch. For this reason, the main purpose of the present invention is to provide a call Analytical method and device to solve one of the above problems

Embodiment 1

[0059] This embodiment describes the application of the softswitch in the international gateway office, so as to realize the source division of the number analysis according to various conditions. In the international gateway office, the softswitch not only needs to clear the landing service but also carry out the transfer service. For example, an incoming call from a British Telecom trunk may be a service that needs to be unblocked by a softswitch, or it may be a service that is transferred to Vietnam. Therefore, the address nature of the called number may be different for the incoming call of the same trunk group, so you can pass The nature of the called address performs number pre-analysis, so that different number analyzers are selected for analysis.

[0060] For example, according to the international telephone numbering rules, the international direct dialing code of my country is 86, and the international direct dialing code of Vietnam is 84. Assume that a softswitch i...

Embodiment 2

[0063] This embodiment describes entering into different number analysis processes according to the type of the calling user, so as to implement source division of the number analysis according to various conditions. In the PSTN network, the calling user categories include: operator, ordinary user, priority user, ordinary free user, ordinary regular user, priority free user, priority regular user, etc. These categories indicate the characteristics of the calling user . If in the call pre-analysis on the softswitch side, the pre-analysis condition is configured as "caller type", the pre-analysis values ​​are various caller types specified in the PSTN network; the pre-analysis processing method is "replace the number analyzer", Replace it with the number analyzer set on the softswitch side according to the calling user category. Then use the new number analyzer to analyze the called number, and the call is continued. In this way, in the number analysis configuration of the sof...

Embodiment 3

[0066] This embodiment describes how to use the call analysis method of the embodiment of the present invention to solve the problem that the external module of the soft switch wants to participate in the number analysis process of the soft switch. The softswitch is connected with terminals such as SCP and other softswitches in the actual networking. SCP can provide narrowband intelligent services; other softswitches and this softswitch form a cross-domain network. In some business logic, these external modules may wish to participate in the number analysis process of this softswitch. These external modules can make an agreement with this softswitch: execute a special number analyzer for some calls based on some specific information; The number analyzer implements specific business logic.

Abstract

The invention discloses a method and a device for analyzing calls. The method comprises the following steps: receiving messages from a call bureau on a softswitch; obtaining related information of calling / called number on the softswitch according to the messages; carrying out call pre-analytical matching on the softswitch for the related information of the calling / called number according to pre-analytical matching conditions; and processing the calls corresponding to the successfully-matched related information of the calling / called number on the softswitch. The method for analyzing the calls realizes flexible configuration for number analyzing codes in the softswitch.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a call analysis method and device in a Next Generation Network (NGN for short). Background technique [0002] At present, the Public Switched Telephone Network (PSTN) public telephone network includes a long-distance network and a local network, and the network level is divided into five levels. The long-distance network is composed of four-level long-distance switching centers such as the regional center C1, the provincial center C2, the regional center C3, and the county center C4. The local network is composed of the fifth-level switching center, namely, the end office C5 and the tandem office Tm. [0003] With the development of economy and society and the improvement of telephone penetration rate, the network structure of the telephone network must constantly change to meet the demand. The update of communication technology, especially the emergence of the next-generation...
