Patent ID: 7792985

Claim:
A method for implementing information flow transmission in a Next Generation Network NGN, comprising: setting, in the NGN, a signaling channel for transmitting a signaling flow of an NGN service, and reserving resources for the signaling channel; and transmitting, by a sending terminal and with a highest priority, the signaling flow of the NGN service split from a customer traffic over the signaling channel to a receiving terminal; wherein the NGN comprises an IP access network, an IP core network and an NGN service subsystem; and the process of setting the signaling channel in the NGN comprises: setting an access network signaling channel for transmitting the signaling flow in an IP access network; and setting a core network signaling channel for transmitting the signaling flow in an IP core network; and wherein the process of the sending terminal transmitting the signaling flow of the NGN service split from the customer traffic over the signaling channel to the receiving terminal comprises: transmitting, by the IP access network, the signaling flow of the NGN service split from the customer traffic sent by the sending terminal to the IP core network over the access network signaling channel comprising: recognizing and splitting, by an access node of the IP access network, the signaling flow of the NGN service from the customer traffic, and transmitting, with the highest priority, the signaling flow to an aggregation node over the access network signaling channel; forwarding, by the aggregation node and with the highest priority, the signaling flow in the access network signaling channel to an edge node over the access network signaling channel according to an identity of the access network signaling channel; and sending, by the edge node, the signaling flow to a border node of the IP core network: and transmitting, by the IP core network, the signaling flow sent by the IP access network over the signaling channel to the receiving terminal over the core network signaling channel.
