The invention discloses a method for implementing circuit identification in an optical network unit (ONU) system based on EOC (Ethernet over Coaxial cable). The method comprises the following steps: after initialization, emptying a temporary CNU (Coaxial Network Unit) MAC (Media Access Control) address learning table TT, polling a MAC address learned by each CNU, obtaining the user side MAC address of each user port of each CNU one by one, and writing the MAC addresses into the TT; comparing the TT with a global CNU MAC address learning table TG, and synchronizing the TT into the TG; and transferring messages of the CNUs to an Ethernet exchange chip through an coaxial cable, transmitting the messages to a CPU (central processing unit) according to a message redirection rule, analyzing the source MAC addresses of the messages by the CPU after receiving the messages, searching corresponding serial numbers and user port numbers of the CNUs when judging that the source MAC addresses exist in the TG, analyzing the messages and adding circuit identification information to the messages by the CPU, and finally forwarding the messages by the Ethernet exchange chip. By adopting the method, the corresponding circuit identification information can be added to the messages from the CNUs; and the method has the advantages of lower requirements on hardware, simpleness for implementation, short development cycle and low cost.

A private communications network and method of private communications network operation. One or more communications servers each have connected communications devices. From communications devices users enter called party numbers that may include a carrier access code (CAC) and carrier identification code (CIC). The called party number is checked for a CAC and any identified CAC/CIC is parsed from the called party number. The parsed called party number and the CAC/CIC are passed independently of each other over a private network to a public network gateway server. The public network gateway server directs the parsed called party number to a carrier network identified by the CIC, connecting the user to the called party.

This invention discloses a method for transmitting information on signaling kinks based on No.7 signaling system containing a sending end and a receiving end directing to the link or connecting with the link by a switch point. The method includes 1. adding a virtual relay in the exchange device of send/receive ends, each one is assigned with corresponding circuit identification code(CIC) and arranged in the virtual relay group, the said information includes the route information corresponding to the virtual relay 2. The sending end selects the information only needing transferred on the signaling link to be transmitted to the receiving end by the virtual relay which utilizes original parameters, adaptive parameters or self-defined ISUP information to transfer necessary information.

The invention discloses a call-switching method, a call-establishing method and a call-processing method as well as a device and a system. The call-switching method comprises the following steps: sending a terminal-adding request message with TDM type terminal information, terminal information corresponding to TDM types, IP type terminal information and coded information corresponding to IP types to a media gateway; receiving a terminal-adding response message indicating that the media gateway successfully establishes TDM terminals and IP terminals; sending a switching request message with a circuit identifier cell and the IP type terminal information to a destination substation controller; and receiving a switching request acknowledgement message which is returned by the destination substation controller and carries the TDM type terminal information or the IP type terminal information.

A proxy switch, communication method for use in a mobile network are described. A proxy switch is deployed between a base station subsystem and a mobile station center. It receives signaling messages and either retransmits them, blocks them, converts them, or siphons them to an alternative network. Besides providing an ability to offload offload mobile traffic it provides a platform for new communication services. A mobile communications network has at least one BS, at least one MS, at least one MSC, and at least one switch in communication with at least one of the BSs and the at least one of the MSCs. A BS is in trunk line communication with the switch and the trunk line communication is organized as bearer circuits, each bearer circuit identifiable with a circuit identification code (CIC). The switch receives signaling messages from the the BS and determines if a call corresponding to the signaling message is to be handled by the alternative communication network. If so, the switch assigns a CIC for a bearer circuit for the call and communicates the CIC to the BS. Thereafter, the switch receives information on the CIC-identified bearer circuit and forwards the received information to the alternative network.
