A system and method of communication, comprising establishing a first connection between the user equipment and a first non-public packet switched network which assigns a first non-public packet switched network address to user equipment; establishing an open signaling channel which communicates between the user equipment and a remote server through a cellular telephone network according to a public switched telephone network address associated with an International mobile subscriber identity; communicating an identification of the first non-public network and the first non-public packet switched network address over the open signaling channel to the remote server; and establishing a real time voice communication from the remote server to the user equipment through the first connection based on a call routed through the remote server to the public switched telephone network address.

The invention discloses a fax system and method based on satellite mobile communication. The fax system comprises a first fax machine, a satellite mobile terminal, a mobile communication satellite, agateway station subsystem, a core network, a relay media gateway, a public switched telephone network (PSTN) and a second fax machine. The faxing method comprises the following steps: a data fax method between two first fax machines and a data fax method between the first fax machines and a second fax machine. By using the fax method, the fax service application problem based on a satellite mobilecommunication network can be solved, the fax service interconnection and intercommunication problem of the satellite mobile communication network and a traditional PSTN network is solved, and alternate transmission of voice services and fax services is achieved. In conclusion, the system has the advantages of being complete, high in intelligent degree, convenient to use and the like.

The invention relates to a method and a system for transmitting TDM services in MicroTCA, which includes adding TDM channels on the backplane of a standard MicroTCA platform by using AMC Ports 18 to 20, and adding TDM channels and switching networks on the corresponding AMC boards at the same time. A standard chassis supports 9 slots of TDM services, and each slot provides 32 time slots, which can meet the needs of many services to access the TDM switching network and achieve the purpose of transmitting TDM services on the MicroTCA platform.

The invention relates to a multilevel relativity bearing type automatic mapping method for an electric power communication network, and belongs to the field of electric power communication networks. According to the multilevel relativity bearing type automatic mapping method, through proceeding from the primary production and operation characteristics of electric power and analyzing from top to bottom step by step, a multilevel relativity bearing type model is emphatically established among primary electric power services, electric power communication services and a communication network. In the model, an electric power network resource on the highest layer of the model comprises electric power transmission lines and electric power distribution lines; a communication channel provided by the electric power communication network is a direct resource for supporting the operation and the production of the electric power lines, and electric power services supported by the electric power communication channel comprise relay protection, stability control, and the like; a communication network system formed by a transmission network, a data network and a switch network provides direct support for the communication channel above the communication network system; and an optical cable network is virtually used for bearing and transmitting the communication channel. The relativity multilevel bearing type automatic mapping method has the advantages that graphics among resources at different levels in the communication network are automatically generated and pushed upwards; and the graphics in the communication network are automatically pushed upwards from a transmission layer to a service layer, and difficulties with the transmission layer and the service layer during graphical management of the communication network are solved.
