Embodiment Construction

[0033] The present invention proposes a method for multiple non-collinear time slots to call a collinear time slot, and the purpose is to realize the call between multiple non-collinear time slots and multiple users on the collinear time slot by out-of-office users , And can talk normally.

[0034] The implementation process of the present invention will be described below in conjunction with the drawings.

[0035] figure 1 It is the call flow chart of the method provided by the present invention, and the specific execution steps are as follows:

[0036] Step 101. The out-of-office user calls the user on the co-line time slot through the public signaling digital interface;

[0037] Step 102. The system confirms receipt of the incoming call message;

[0038] Step 103. Determine whether it is the first call between the calling signal and the collinear time slot, if yes, go to step 104; if not, go to step 106;

[0039] Step 104. Record the calling number and called party line time slot;

Abstract

The invention relates to a system that a plurality of non-collinear time-slots call a collinear time-slot, and a method in the communication technical field. The system comprises an outside user, anda plurality of users on a collinear time-slot; the outside user is connected with the users on the collinear time-slot through a common digit interface. The method is to make calls and talks among a plurality of users on a plurality of non-collinear time-slots and one collinear time-slot, and includes processing the calls and the time-slot release. The method provided by the invention realizes that through a plurality of non-collinear time-slots, the calls and the talks can be made among the outside users and a plurality of users on one collinear time-slot, solves the squeak problem in the prior art as a group calling is made, and saves the time-slot resource on a digit 2M.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a system and method for calling a collinear time slot from multiple non-collinear time slots. Background technique [0002] ISDN: ISDN (Integrated Services Digital Network) is a communication network developed and evolved based on the Integrated Digital Telephone Network (IDN). It can provide end-to-end digital connections to support voice and non-voice A variety of telecommunications services within. Users can access the network through a limited set of standard multi-purpose user-network interfaces. [0003] ISDN supports a wide range of services, not only can provide voice services, but also can provide various non-speech services such as data, image and fax. Not only can provide instant connection when users need to communicate, but also provide dedicated line services. [0004] ISDN-PRI and ISDN-BRI: The former (ISDN-PRI) is also called ISDN 30B+D, that is, 30 B...
