Abstract: The provided is a construction method for a flood storage area ecological wetland oriented to multi-target collaborative promotion. The construction method includes: I. carrying out ecological wetland construction on a flood storage area by taking promotion of agricultural production as a goal; II. according to a water purification target of the flood storage area of the ecological wetland and a current pollution condition in the flood storage area, constructing the ecological wetland based on improvement of the water purification target when the flood storage area does not reach the water purification target at present; and III, in order to improve the biodiversity, carrying out the following ecological wetland construction on the flood storage area. In the method, agricultural production, water purification and biodiversity improvement of the flood storage area are comprehensively considered. The method is the most effective way for multi-target collaborative promotion of the flood storage area.

Abstract: In a file repair method for a user equipment (UE), the UE receives a target file multicasted by a network side in a file download transmission (FDT) manner. The method includes transmitting, by the UE, a multicast attempt repair request for the target file to the network side in a first time period after determining that the target file needs to be repaired, where the first time period does not exceed a time period of a Back-off time of a current session, receiving, by the UE, a feedback message transmitted by the network side, where the feedback message instructs the UE to perform multicast repair, and performing, by the UE, the multicast repair on the target file in response to the received feedback message.

Abstract: System and methods for mitigating circuit-switched fallback delay. A user equipment may initiate connection of the user equipment to a packet-switched network. A request may be sent by the user equipment to the packet-switched network to access a circuit-switched service. A timer may be started to determine elapsed duration between sending the request and receiving a response from the packet-switched network that confirms resource allocation to access the circuit-switched service. The user equipment may select in response to timer expiration, indicating absence of response to the request, a particular algorithm when implemented initiates connection of the user equipment to a particular circuit-switched network to access the circuit-switched service.
