An identification code circuit for a receiving coil in a magnetic resonance imaging system, is embodied in a main coil. The circuit has a fixed resistance for generating the identification code of the main coil. The main coil has a socket for connecting a sub-coil, so that a coil plug of a sub-coil can be plugged into the socket for connecting to the main coil. The identification code circuit also has a regulating resistance and a sub-coil switch corresponding to the socket. The coil plug of the sub-coil is plugged into the socket to close the sub-coil switch, so that the values of the regulating resistance and said fixed resistance are added together to form a combined resistance value. After said main coil has been connected to a magnetic resonance imaging system, an identification code source voltage value across the combined resistance value is the identification code of the combined main coil and sub-coil. A receiving circuit identification code thus can be generated simply and with reduced cost.

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.

What is required is a method and apparatus for communicating between at least one base station and a core network in a wireless communication system. Signaling messages and voice streams are carried using the Packet Switching Protocol (IP). At least one Voice over IP flow is identified using the CIC field (Circuit Identification Code). The CIC field can be interpreted as the UDP port number of the voice IP stream. Furthermore, a synchronization source or contribution source field of an RTP header may be used as the CIC field.

The invention discloses a method and monitoring equipment for realizing association of a calling control protocol and a media control protocol. the method comprises a calling process performed by soft exchanging equipment of a NGN network aiming at public switched telephone network (PSTN) equipment; when determining the used circuit identifying code in the current calling process does not determine the calling association relation, according to the time interval of calling process message interaction carried out by the PSTN equipment and the soft equipment before the current calling process and during the calling process using the circuit identifying code, a destination node identifier is determined in each destination node identifier which is not determined the calling association relation; the destination identifier and the circuit identifying code are determined to form the calling association relation when the destination node identifier is judged to be associated with the media gateway control protocol events; the invention automatically studies the corresponding relation of CIC and TID under the condition that SS does not provide the corresponding relation of CIC and TID to a monitoring system, thus improving monitoring performance.

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 typesto 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. The embodiment of the invention can avoid the situations of call failures caused by the mismatched TDM terminals which are respectively distributed at the destination substation controller and a core network side and improve the call success ratio.

The embodiment of the invention discloses a call handover method, a call handover device, a media gateway and a base station controller. The call handover method comprises the following steps of: sending a terminal-increasing request message to the media gateway, wherein the terminal-increasing request message carries TDM (Time Division Multiple) type terminal information, coded information corresponding to a TDM type, IP (Internet Protocol) type terminal information, and coded information corresponding to an IP type; receiving a terminal-increasing response message which indicates that the media gateway successfully establishes a TDM terminal and an IP terminal, and sending a handover request message to a target base station controller, wherein the handover request message carries a circuit identification code cell and the IP type terminal information; and receiving a handover request acknowledge message returned from the target base station controller, wherein the handover request acknowledge message carries the TDM type terminal information or the IP type terminal information. The embodiment of the invention can avoid the condition that the call failure is resulted from the mismatch between independently-assigned TDM terminals at the target base station controller and a core network side, and increases the success ratio of calling.

A system and method for performing a traffic process in an integrated network of a VoIP (Voice over Internet Protocol) network and a PSTN (Public Switched Telephone Network) are provided. The system includes: a softswitch which has a plurality of ASPs (Application Server Processes), transmits a data signal to other nodes through an ASP that is selected from among the ASPs, and transmits a heartbeat request message when a CPU (Central Processing Unit) utilization ratio and an SCTP (System Control Transmission Protocol) level congestion of the ASPs exceed respective reference points according to AS (Application Server) / ASP information; and a signaling gateway which updates the reference points of the CPU utilization ratio and the SCTP level congestion in response to the heartbeat request message and transmits a heartbeat acknowledgement message to the softswitch, and checks the CPU utilization ratio and the SCTP level congestion for a plurality of active ASPs within a predetermined CIC (Circuit Identification Code) or SSN (Sub-System Number) range according to the AS / ASP information, to determine the selected ASP when the signaling gateway receives data signal from outside and traffic is distributed.

The invention provides a method and a system for automatically obtaining a speech path number in a No.7 signaling link. The method comprises the following steps of monitoring whether request call signaling exists in the signaling link, if yes, extracting a circuit identification code in the request call signaling and recording all speech path channels managed by the signaling link; monitoring whether end call signaling corresponding to the request call signaling exists in the signaling link according to the circuit identification code, if yes, ending the recording of all speech path channels and respectively storing a recording file generated by each speech path channel; and analyzing all recording files and finding the recording file which conforms to the call voice behavior, wherein the speech path channel corresponding to the recording file is the speech path channel for this call, and the circuit identification code is the speech path number of the speech path channel. The method and the system can automatically obtain the circuit identification code corresponding to each speech path channel in the signaling link and automatically sense whether the speech path number of the speech path channel changes, so that the loss of monitoring data can be avoided.
