Embodiment Construction

[0033] Please refer to Figure 1, it is a digital trunking system with a new recording server functional entity on the basis of the existing digital trunking network based on CDMA2000 technology. As shown, the system includes:

[0034] MS, it is a terminal device that can support storage of user information, group information, scheduling area judgment, and response to traditional group paging and paging trunking services;

[0035] BSS, which includes BTS supporting group calls, BSC and PDC interacting with the network side;

[0036] PDS, which can realize call control and talk right management of group calls;

[0037] PHR, which can save the registration information and location information of cluster users and groups, realize the authentication, authorization and billing functions of cluster users, as well as the location update and group management functions;

[0038] RS, the RS implements the negotiation and recording functions with the PDS voice channel, and saves the rel...

Abstract

The present invention discloses a digital cluster system. A voice recording server is added on the basis of the existing digital cluster network entity; the voice recording server realizes the functions of negotiation with the voice channel of a dispatching server and voice recording, and stores related calling information to a dispatching home location register. The establishing and the releasing steps of the cluster group calling of the system are that: first, the voice recording server negotiates a voice chain with the dispatching server during the establishment process of the cluster group calling; second, after the cluster group calling is established, the voice recording of the cluster group calling is performed and is stored, and the corresponding calling information is recorded into the database of the dispatching home location register; third, the dispatching server informs the voice recording server to stop the voice recording of a specific cluster group calling during the releasing process of the cluster group calling. The present invention solves the problem that the existing digital cluster system can not realize the functions of fully recording all the cluster group calling, searching the history recording and playing back on the premise of not influencing the normal cluster group calling, and thus can meet the operation requirement of the user of certain specific professions.

Description

technical field [0001] The invention relates to the field of digital trunking communication, in particular to a digital trunking system and a method for establishing and releasing a trunking call. Through the system and method, functions such as recording, querying and playback of all calls in the trunking system can be realized. Background technique: [0002] The mobile communication technology has been developed to the third generation, and trunking communication has increasingly become an indispensable communication service. Trunking communication refers to a dedicated dispatching communication method, including dedicated command and dispatching communication. During use, trunking users can join calls at the same time, and calls work in simplex mode. In a broad sense, various wireless communication systems with dispatching communication functions, including wireless intercom systems, can be included in the category of trunking communication systems. [0003] Trunking com...
