Problems solved by technology

[0010] Since the message between the NGN gateway and the softswitch is transmitted through the IP network, there will be a certain delay in the message when the network condition is not good
Traditional switches have a limited waiting time for HookoffAck messages in channel-associated signaling, and some switches only have a waiting time of 20 milliseconds or even shorter; Up to hundreds of milliseconds, in this case, the traditional switch will cause the call to fail due to waiting for the HookoffAck message to time out
[0011] It can be seen that the above-mentioned method for NGN system to realize channel-associated signaling is completely controlled by the softswitch, that is, the NGN gateway will respond to the peer switch with the HookoffAck message only after receiving the occupancy confirmation message of the softswitch. The impact of the delay on the response time limit of the NGN gateway message will reduce the success rate of the associated call

Embodiment Construction

[0031] The next generation network system provided by the present invention realizes the method for road-associated signaling, comprising: the exchange sends a HookoffFw message to the NGN gateway; the NGN gateway sends an occupation message to the softswitch after receiving the message, and at the same time, sends a HookoffAck response message to the exchange; After receiving the response message, the switch starts to interact with the NGN gateway for the sender signal; when the NGN gateway finishes the sender signal interaction, if it receives the occupancy confirmation message of the softswitch, it continues the follow-up process of the call; If the occupation confirmation message is not received, the call is released.

[0032] The above-mentioned technical solution of the present invention will be described in more detail below in conjunction with the accompanying drawings and preferred embodiments.

[0033] Under the condition that the NGN network has a certain time delay...

Abstract

A method for achieving channel associated signaling of the next generation network system comprises the following steps: (a) transmitting an occupation message to a soft switch after a gateway receives a call request message transmitted by a switch, and simultaneously transmitting an off-hook response message to the switch; (b) carrying out register signal interaction with the gateway after the switch receives the response message; and (c) monitoring an occupation acknowledgement message transmitted from the soft switch in the register signal interaction process of the gateway, and continuing the subsequent calling process if the gateway receives the occupation acknowledgement message when the register signal interaction is ended, or else, releasing the call. The method has the characteristic of relatively longer register signal interaction time, and can adjust the message interaction process, thereby minimizing the influence caused by network delay.

Description

technical field [0001] The invention relates to a network element signaling interaction method of a next generation network (NGN, Next Generation Network), in particular to a method for realizing channel-associated signaling in an NGN system. Background technique [0002] In the NGN system, the implementation of channel-associated signaling is jointly completed by the gateway and the softswitch system. The gateway side mainly implements the channel-associated signal interaction with the traditional switch, while the softswitch implements the control and service processing of the channel-associated signaling. [0003] The process of initiating a channel-associated call from a traditional switch to an NGN is as follows: figure 1 shown, including the following steps: [0004] 101: The traditional exchange sends a HookoffFw message to the NGN gateway, and initiates a channel-associated signaling call; [0005] 102: The NGN gateway sends an occupation message to the softswitch...
