Abstract: Example configuration methods and apparatus are described. An example communications system includes a master node and a secondary node that jointly provide a service for a terminal. One example method includes generating configuration information for a signaling radio bearer (SRB) by the secondary node, where the SRB is used to transmit a radio resource control (RRC) message between the secondary node and the terminal. The secondary node sends the configuration information for the SRB to the master node, so that the configuration information for the SRB is sent to the terminal through the master node. The secondary node receives a result of configuring the SRB by the terminal by using the configuration information for the SRB. In this way, the SRB can be established on the secondary node, and used for RRC message transmission between the secondary node and the terminal.

Abstract: Disclosed is a method for recovering phosphorus from sludge rich in chemical phosphorus precipitates using a high-protein biomass waste, comprising introducing the sludge rich in chemical phosphorus precipitates into an anaerobic fermenter, adding a certain amount of a high-protein biomass by-product, sealing the fermenter and fermenting for 4-7 days. The method can effectively increase the phosphorus release efficiency from the sludge, and also generate volatile short-chain fatty acids and ammonia nitrogen in high concentrations. After dewatering, phosphorus and part of ammonia nitrogen can be recovered in a form of high-purity struvite crystals only by addition of a magnesium salt and adjustment of pH to 7.5-9.0. The volatile short-chain fatty acids can be used as an economical carbon source. The method allows simultaneous utilization of two solid wastes to recover carbon, nitrogen and phosphorus resources, and can reduce the usage of chemical reagents, saving the treatment cost.

Abstract: Provided in embodiments of the present application are a junk feature acquisition method, an apparatus, a server and a readable storage medium. The method is used on a first server, and the method comprises: obtaining storage paths to be analyzed; storage paths to be analyzed being: a storage path of a file corresponding to an application (app) installed on an electronic device; filtering out a target storage path out of the storage paths to be analyzed, the target storage path comprising: a storage path matching a file feature of a non-junk file in a pre-determined white list; making a storage path obtained by filtering into a junk feature. Using a method provided in an embodiment of the present application to acquire a junk feature can increase junk feature acquisition effectiveness and decrease labor consumption.

Abstract: The present invention discloses a method and system for obtaining access information in a Multimedia Broadcast/Multicast Service (MBMS). The method includes the following steps: during an eMBMS session, a broadcast/multicast service center (BM-SC) configures access information in one or more MBMS session signaling, and sends the MBMS session signaling to an MBMS gateway within a service area of the BM-SC; wherein the access information at least includes radio access technology type information. The present invention also discloses a method and system for charging in an MBMS. The methods and systems of the present invention can take the access information including the radio access technology type as the basis of charging, supply communication operators with a charging manner of distinguishing radio access technology types, and adopt different rates corresponding to the MBMS service areas of different radio access technology types, and thus charging can be further detailed.
