Embodiment Construction

[0015] Fig. 2 has shown the network structure involved in the present invention, among the figure fixed network user and mobile user are connected to PSTN network by fixed network exchange and mobile exchange respectively, each extension user of PABX is connected to local exchange by PABX thereby access PSTN network, The ring-back tone service server CRBTS is connected to the PSTN network to complete the storage, management and playback of the ring-back tone. The mode utilizes this service management point to carry out operations such as customizing its personalized ring back tone. Typically, PABX enterprise users can uniformly customize the ring-back tone of each extension in a certain way, such as customizing different extension numbers in groups, such as adopting the ring-back tone for broadcasting enterprise product information advertisements for all extension numbers of the sales department. The R & D department adopts advertising ring back tones that reflect the company's...

Abstract

This invention discloses a method and a system providing ring-back service to PABX including: a user small exchanger receives the call request from a calling user by a called party exchanger, the PABX restrains traditional ring-back sounds and sends extension ring inform information with the called number to the called exchanger, which picks up the called number and sends call successive information to the ring-back server after receiving the ring inform information, the server inquires about the ring-back sound designed by the called number and informs the called exchanger to play it to the calling user.

Description

technical field [0001] The invention relates to ring-back tone service technology, in particular to a method and system for providing ring-back tone service to PABX (Private Branch Exchange). Background technique [0002] During a telephone call, the state information of the line between the switching device and the user equipment is notified to the user through call process tones. Common call process tones include dial tone, busy tone and ringback tone, etc., which are usually fixed by the system. . In the prior art, the PCT patent "Advertising method by using ring-backtone" with the patent number WO 00 / 49793 proposes a method of replacing the ordinary ring-back tone with the ring tone set by the network, thereby allowing the network to pass the ring-back tone To play advertising information. Aiming at the problem that the user cannot independently set the ringback tone in this technology, PCT patent WO 03 / 071815 "Method and Apparatus for providing subscriber-based ringba...
