Problems solved by technology

If the call of the ISDN user in the end office is connected to the ISDN processing module of the tandem office through NO. It is undoubtedly very cumbersome and complicated to convert with ISDN signaling messages. In addition, most ISDN new service signaling messages are processed by the end office, and it is impossible to transmit them to the tandem office for processing through NO.7. In this way, many new ISDN services It cannot be realized in the original way
[0010] Since the existing technology is implemented based on PSTN users, how to transmit special information for ISDN user access, such as transmission medium request, access transfer and connection number, and ISDN2B+D has two B channels, the same How to deal with the two calls initiated by the calling number, how to judge the forwarding on busy service, etc., the existing technology does not have a good solution, which limits the functional application range of the No. 7 access tandem office and increases the number of transformations cost

Embodiment Construction

[0026] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] What the present invention provides is a method for realizing ISDN user access by using No. The function of accessing the tandem office makes it suitable for the access of two different users of PSTN / ISDN at the same time.

[0028] Below in conjunction with accompanying drawing, the implementation of technical solution of the present invention is described in further detail:

[0029] Such as figure 1 As shown, after the No. 7 access tandem office is introduced, the calls of the ISDN access users at the end office are all tandem to the tandem office for processing.

[0030] Such as figure 2 As shown, in the call flow when the ISDN access user of the present invention is calling, the tandem office can know that the calling party is an ISDN user according to the sign in the IAM (Initial Address initial address) message. Send the ...

Abstract

This invention discloses one method to realize ISDN user interface by use of seven signal, which comprises the following steps: establishing seven number interface collection place and end place connection and aligning user data; adding said collection place to process the said ISDN user main call and called situation and to send relative information to ISDN call; This invention method need no alternation of any network rack and hardware to extend business function.

Description

technical field [0001] The invention relates to a program-controlled switching access technology in the communication field, in particular to a method for realizing user access by using No. 7 signaling in a communication network. Background technique [0002] Today, with the rapid development of the communication industry, only relying on high technology and high quality to ensure trouble-free telephone communication can no longer meet the needs of users, and at the same time it is not enough for telecom network operators to maintain an advantage in market competition, even if they adopt low prices The strategy, the role played in the competition is also limited. The needs of users require operators to quickly provide diversified value-added services to meet their various needs. This market diversification trend requires that more and stronger intelligent services and mobile services must be introduced into the network to improve the network's adaptability to services. [...
