Abstract: Disclosed are a method, a device and a system for data communication control. In the method for data communication control, data sent from a first communication device is received by a data forwarding device, where the data is transmitted through at least two types of physical interfaces in sequence. The data is then forwarded by the data forwarding device to a second communication device that is preconfigured. During the process of sending the data by the first communication device, the data is physically isolated by at least two types of physical interfaces, and then forwarded to the second communication device that is preconfigured. Even if the first communication device is illegally invaded by outsiders, the outsiders only know the IP address of the first communication device but fail to know the IP address of the destination of the physically isolated data.

Abstract: A call forwarding device based on an IMS includes a terminal and an IMS communication system connected to the terminal. The IMS communication system is respectively connected to an IMS special service number device, an IMS user database and an IMS maintenance device. After the terminal establishes a communication with the IMS special service number device, a forwarding condition and a forwarding number set through an IVR, and a calling number and a called number of the terminal are saved in the IMS user database. When the calling number of the terminal dials the called number, the IMS communication system detects a status of the called number, and a communication is established between the calling number and the forwarding number of the terminal according to the forwarding condition.

Abstract: A method and a device for two-stage dialing for audio and video communications based on IMS. The call request sent from the user terminal is acquired, where the call request includes the target number that the user terminal dials on the IMS, and the target number is allocated by the IMS. The communications link is established between the user terminal and the IMS according to the target number. The operation navigation prompt is sent to the user terminal, and the service confirmation information of the two-stage dialing fed back from the user terminal according to the operation navigation prompt is received. The target number is dialed through the user terminal, and the service option selected by the user is confirmed by receiving the service confirmation information for the two-stage dialing fed back by the user terminal based on the operation navigation prompt.

Abstract: The disclosure discloses a technology for communication between different instant messaging protocols and SIP protocol, the technology comprises a conversion method, a gateway and a device, wherein inputting first information using an instant messaging non-SIP standard protocol or second information using a SIP standard protocol; converting the first information using the instant messaging non-SIP standard protocol into the second information using the SIP standard protocol, or converting the second information using the SIP standard protocol into the first information using the instant messaging non-SIP standard protocol; outputting the second information using the SIP standard protocol or the first information using the instant messaging non-SIP standard protocol. By means of the method, the disclosure provides technical support for audio, video and information communication between instant messaging systems and communication systems of the SIP standard protocol.

Abstract: Disclosed is a secure communication method of an IMS system based on a key file. The method includes obtaining an IMS account before sending the account and authentication information to a background server by a UE; generating an electronic work order by the background sever according to the received authentication information to enable customer service personnel to manually audit the authentication information and the IMS account according to a preset rule and the electronic work order; generating an encrypted key file and sending the file to the UE when determining the correctness of the authentication information and the IMS account; and activating the IMS account according to the key file and performing network communication according to the IMS account. The disclosure improves the communication security of the IMS system by using the activated IMS account for network communication.

Abstract: A method for triggering IMS communication based on a data communication protocol. In a data communication protocol, the various collected sensed data is defined in accordance with regulations specified in the present invention. Connection to a mobile phone, a computer or a hardware device or the like is established by Bluetooth, or by a virtual serial port, or by RS485 or RS232 or the like. If receiving set data matching the data communication protocol, the mobile phone, the computer or the hardware device or the like into which an IMS system client program is embedded automatically triggers the embedded IMS system client program to communicate through an IMS system. Different telecommunication numbers are triggered by different data. The data between the mobile phone, the computer or the hardware device and the data communication protocol is in a SIP-MESSAGE format.

Abstract: A network device may include one or more processors. The one or more processors may receive a call from a services processor to allocate network address translation resources for a data packet. The one or more processors may determine an identifier associated with the services processor. The one or more processors may allocate network address translation resources using a network address port translation manager based on the identifier. The network address translation port manager may be a two-level port bitmap management system that determines a translated source port for the data packet.
