Abstract: The embodiments provide a bandwidth scheduling method and an apparatus to resolve a problem in the prior art that a transmission delay is relatively large and user experience is relatively poor when a baseband unit and a radio remote unit are networked by using a passive optical network. The method includes: allocating, by a baseband unit, radio resources used for data transmission between N first radio frequency units and a terminal to the N first radio frequency units connected to the baseband unit, where N is an integer greater than 0; and then allocating, by the baseband unit based on the radio resources of the N first radio frequency units, bandwidth resources used for data transmission between the baseband unit and the N first radio frequency units to the N first radio frequency units.

Abstract: The present invention discloses a method for synergistic stabilization/solidification of red mud and phosphogypsum. The method includes: grinding and mixing red mud and phosphogypsum, adding deionized water, uniformly stirring the mixture to prepare slurry, adjusting a pH value of the slurry to 7.5-8.5, adding a conditioner and conducting stirring, adding a stabilizer and an anti-permeability agent, uniformly stirring the mixture to obtain a gel product, and conducting solidification for 12-24 h to solidify the red mud and phosphogypsum, to obtain a red mud-phosphogypsum solidified material. In the present invention, the neutralization reaction between acidic ions in phosphogypsum and basic ions in red mud is adopted to reduce a pH value of the red mud and a transfer capability of pollutants in waste residues; synergistic solidification processing is conducted on two types of solid wastes: red mud produced in the aluminum smelting industry and phosphogypsum produced in the phosphorus chemical industry.

Abstract: A method of communication between a base band unit (BBU) and a plurality of remote radio units (RRUs) via a point-to-multipoint time division multiplexing passive optical network (TDM-PON) system is provided. The method can be performed by an ONU and comprises receiving Ethernet packets from the Ethernet interface of an RRU of the plurality of RRUs, performing time-division multiplexing of the Ethernet packets to generate multiplexed packets, storing in a buffer of the ONU the multiplexed packets based on a pre-determined buffer starting time and buffer size, packaging the multiplexed packets in the buffer to fixed length transmission blocks (TBs) having pre-allocated time slots for TDM-PON upstream transmission, and transmitting the TBs to an optical line terminal (OLT) that is communicatively coupled to the BBU such that no contention of TBs occurs at the OLT.

Abstract: The present invention discloses a method and a base station for allocating bandwidth for subscriber stations and a backhaul station through taking into joint consideration uplink and down bandwidth requests from respective subscriber stations in a wireless single-hop self-backhaul network. Upon receipt of information on bandwidth requests from the subscriber stations, the base station takes uplink and downlink bandwidth requests into joint consideration, allocates bandwidth for the subscriber stations and the backhaul station, and then notifies the subscriber stations and the backhaul station. Since bandwidth allocation is no longer based on uplink and downlink resources separately, a relatively high system bandwidth utilization ratio can be achieved and uplink and downlink bandwidth fairness for asymmetric traffic be ensured even if the network is overloaded.

Abstract: In this invention, a proxy device is introduced between control device and implementing device in a communication network, to achieve the management related to work status monitoring between control device and implementing device, so that the load of control device handling message(s) related to status monitoring. Specifically, the proxy device firstly obtains the work status information of multiple implementing devices, and reports them to the control device via one or more uplink report messages; after receiving the uplink report message(s) from the proxy device, the control device obtains the work status information of multiple implementing devices based on the above uplink report message(s). The solutions in this invention are especially applicable to device status monitoring based on heartbeat mechanism in soft switch network.

Abstract: The objective of the present invention is to provide a solution for detecting timeslot conflict between Optical Network Units (ONUs) in an Optical Line Terminal (OLT). When all ONUs are deactivated and there is still any light signal in the upstream, each ONU is notified to switch off the power supply of its transmitter one by one to detect whether there is any failure ONU; when all ONUs are deactivated and there is no light signal in the upstream, the failed ONU can be located through ranging the ONUs separately. The solution can be implemented through software update, without affecting the intrinsic hardware design.
