A method relates to adjusting the ring net bandwidth of embed resilient packet ring dynamically and nondestructively, through adding link volume control system into processing layer of synchronous digital network implements the dynamical and nondestructive adjustment of ring net bandwidth of RPR resilient packet ring embedded in SDH / SONET. When increasing ring net bandwidth, it firstly increases the bandwidth among the processing layer nodes of SDH / SONET, then starts the link volume control system in the SDH / SONET processing layer. The link volume control system nondestructively increases the actual bandwidth of processing layer ring net, finally increases the bandwidth of RPR processing layer ring net: When reducing the bandwidth of ring net, it firstly reduces the bandwidth of RPR processing ring net, then starts the ling volume control system in the SDH / SONET processing net. The link volume control system nondestructively reduces the actual bandwidth in SDH / SONET processing layer link, finally reduces the bandwidth among the processing layer nodes of SDH / SONET.

The invention provides an anti-counterfeiting method based on a high-fidelity hidden figure and an anti-counterfeiting system thereof, and belongs to the technical field of counterfeiting prevention. A surface figure, underlying figures and the corresponding relation thereof are analyzed by using a hidden figure print pre-printing analysis module so that concrete parameter settings are generated. Then the multilayer high-definition underlying figures are hidden by using a high-fidelity hidden figure digital net hanging module under the full-color high-quality surface figure. The high-fidelity hidden figure digital net hanging module performs image quality distortion prediction and optimization compensation for the set printing mode, plate-making printing is performed on the optimized and compensated high-fidelity halftone net figure, a high-fidelity anti-counterfeiting print is outputted, and an appropriate detection means is selected to detect the high-fidelity anti-counterfeiting print so that the anti-counterfeiting objective can be realized. According to the anti-counterfeiting method based on the high-fidelity hidden figure and the anti-counterfeiting system thereof, the quality of the surface figure can be effectively enhanced, the selection range of the surface figure can be enlarged, and the underlying figures are large in modulation amplitude, high in contrast, great in visual effect, high in resolution and wide in the range of color gradation so that the hidden figure anti-counterfeiting means is enabled to be diversified and the anti-counterfeiting performance can be effectively enhanced.

The invention discloses an implementation method for improving the circuit quality of an Integrated Services Digital Network (ISDN). One side of the ISDN is provided with a special signal channel B for sending an error correcting code; a system comprises two calling sides, including a calling terminal and a called terminal, and the two calling sides establish the special signal channel B for sending an the error correcting code; the calling terminal makes H.211 protocol data into a data packet and configures adaptive error correcting code for the data packet; and the calling terminal sends the data packet to the called terminal. The system and the implementation method provided by the invention arrange the special signal channel B for sending the error correcting code on one side of the ISDN network to reduce burst bit errors and slip codes and changes a frame format of the data into a packet format to enhance the stability and the safety of data transmission; and in particular, the implementation method combines the strict data transmission format with an error-correcting technology, so that the transmission quality of the ISDN network circuit is improved greatly.

The present invention provides obtaining mobile users integrated services digital network number method. When radio network controller (RNC) completes interface signaling connection with service universal grouping wireless service support node (SGSN), SGSN judges whether local existing mobile users integrated services digital network number (MSISDN), if existing then not processing; otherwise SGSN obtaining mobile users MSISDN number from home location register (HLR); SGSN transmitting mobile users MSISDN number to RNC. Three modes can be used for SGSN transmitting mobile users MSISDN number to RNC, i.e. configuring obtaining mobile users MSISDN number requesting response message method; utilizing increasing recording MSISDN number public ID message method; or directly in public ID message permanent non-accessed layer user identification cell recording MSISDN method. The present invention can make RNC obtaining mobile users MSISDN number.

A method for interface an IPABX and a local exchange includes the steps of: processing a call originated from an IPABX by a local exchange having one discernible individual by binding a plurality of data transmission lines, that is, a data transmission line trunk group; and processing a call destined to the IPABX through the local exchange. Since the directory number can be managed by a group name, stepping up from the method for fixing the directory number to the line, the expense for the line can be reduced. In addition, the problem of separation between the origination line and the destination line as in the conventional method that the trunk line and the PRI line are together used is settled. Moreover, since there is no need to allocate an additional signaling point, an expense possibly incurred for the allocation of a signaling point and consumption of the signaling point resource can be prevented.

The present application discloses a private network MPTCP authentication method and system, wherein the method includes: the public data network gateway PGW sends the ISDN number of the user equipment UE and the IP address allocated for the UE to multiple channels in advance. Gateway MP_GW; when an MPTCP link is established between the UE and the MP_GW, during the MPTCP three-way handshake process, the UE and the MP_GW use the ISDN number and the The IP address generates an encryption key, uses the encryption key to encrypt the session key to be sent to the other party, and uses the ISDN number and the IP address to decrypt the received session key to obtain the other party’s session key. By adopting the invention, the potential safety hazards existing in the MPTCP protocol can be effectively overcome.
