Disclosed is a device for providing compatibility with passive optical networks, wherein two uplink burst clock and data recovery units respectively recover received uplink data in accordance with two standards, and respectively transmit the recovered uplink data to their respective uplink delineation, descrambling and forward error correction (FEC) decoding units; then the two uplink delineation, descrambling and FEC decoding units perform delineation on the received recovered uplink data in accordance with two standards, and after the delineation is successful, transmit processed Gigabit Passive Optical Network Transmission Convergence (GTC) frames to a GTC deframing unit; finally, the GTC deframing unit transmits the deframed data to different processing units for processing. Also disclosed are a method for providing compatibility with passive optical networks, an optical line terminal, and a computer storage medium.

The present invention discloses a communication method and communication equipment for low-cost user equipment, wherein the method includes: a control station acquires low-cost user equipment information of low-cost user equipment in a communication system; Generate user equipment management policy information; the control station communicates with the low-cost user equipment according to the user equipment management policy information. The present invention solves the problem that the existing network cannot be effectively used for communication of low-cost user equipment, which causes the increase of the investment cost of the telecom operator's network construction, effectively saves the investment cost of the telecom operator's network construction, and maintains stable customers resources while improving communication efficiency.

The present invention provides a message transmission method and device. The method includes: a first network device receives a first message sent by a second network device through an inter-system cascading port, and adds a first message to the first message. The remote RMT identifier is used to obtain the second message; the first network device judges whether it is necessary to configure the Perform pruning processing on the second message; if the sending port of the second message is a multi-homing port, the first network device performs pruning processing on the second message; if the second message The sending port is a single-homing port, the first network device deletes the first RMT identifier in the second message, and sends the first message through the single-homing port after obtaining the first message ; In this way, packets can be forwarded with high reliability in a multi-homing scenario.

An evolution system, frame compatible with diverse frequency range Wimax systems and a production method thereof are disclosed, sub-carrier wave and circulation prefix of the compatible Wimax system are the same as each other, number N of the evolution system IFFT is determined to be larger than or equal to sum of numbers of IFFTs corresponding to each compatible Wimax system; in accordance with the number and spacing of the sub-carrier wave of the Wimax system, transmission rate of the evolution system is obtained; data points of the signal are transmitted according to the transmission rate as well as coded and modulated; the data points carrying information of diverse frequency range Wimax systems are arrayed at diverse positions of N point IFFT in terms of each system frequency range, these position are not mutually superposed; the arrayed N data points is performed IFFT operation of N point at each time so as to transform to OFDM time frequency symbols, and the circulation prefix having the length same as the Wimax system is added to the OFDM symbols which is then transmitted; a plurality of symbols combine into a frame. The invention enables the terminals of diverse frequency range Wimax systems to be accessible to the evolution system.
