Embodiment Construction

[0027] In the present invention, when the old switch is transformed, it is connected to the media gateway through an inter-module connection relay, making it a module of the media gateway. Then use the semi-fixed connection method to provide fixed tones.

[0028] The semi-fixed connection means that in the program-controlled switching system, a transparent path is provided between the two links of the semi-fixed connection, that is, the two links are not physically fixed, but controlled by the program. A connection is established between the two. This can improve the flexibility and accuracy of the connection.

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] As shown in Figure 1, the media gateway and the switch are connected through an inter-module connection relay. The dial tone that the switch user needs to hear when off-hook and the busy tone that the other party needs to hea...

Abstract

The present invention discloses a method providing an immobile sound in an access equipment, which comprises the following procedures: the immobile sound resource on a media gateway is fixedly jointed to a time slot of the exchange network of the media gateway, and the time slot is called time slot A; a circuit between a media gateway and an exchanger module is half-fixedly jointed to a time slot of an exchange network of a media gateway, and the time slot is called time slot B; the time slot A and the time slot B are half-fixedly jointed; a circuit between a media gateway and an exchanger module is half-fixedly jointed to a time slot of an exchange network of an exchanger, and the time slot is called time slot C; when the client makes a call, the soft exchange is reported by the media gateway, the soft exchange informs the media gateway to play the immobile sound to the client, the client time slot and the time slot C are connected by the media gateway, and the telephone plays the immobile sound. The present invention does not need to select the connecting circuit between the exchange time slot and the module at each dynamic state, and the stability and the efficiency of the system can be improved.

Description

technical field [0001] The present invention relates to the field of NGN (Next Generation Network, next generation network), in particular to a method for providing fixed tone in an access device. Background technique [0002] The PSTN (Public Switched Telephone Network, Public Switched Telephone Network) network of a traditional operator has been in operation for quite a long time, and once brought huge benefits to the operator. However, the PSTN equipment on the existing network cannot provide new services due to the long operating time, complex models, and aging equipment. However, users have increasingly strong demands for personalized services, so traditional operators need to optimize and transform the PSTN network. [0003] It is a good solution to transform the existing PSTN end office and use it as an access module of the media gateway in the NGN network. Softswitch technology provides an ideal platform for users under the old PSTN equipment. But in terms of techn...
