Problems solved by technology

If this happens, there will be more data accumulated on the receiving side, so that the reassembly function needs to process a lot of SDU data at a time and submit them to the upper layer, resulting in an instantaneous increase in the processing capacity of the chip
At the same time, if the voice business is processed, this situation will further lead to serious delays in the voice

Abstract

The invention provides a method for reporting a data receipt state in a private network wireless communication system. The method comprises the following step: after a reordering timer is timed out, sending a state PDU if the following sending conditions are met: Condition 1, the packet loss rate for data receipt between the VR-MS and the VR-H is low; and Condition 2, a state forbidding timer is in a closed state or is in a running state for certain time. The method has the advantages that more feedbacks on receipt conditions can be achieved, occupation of excessive sending vacant resources can be avoided, a receipt state between the VR-MS and the VR-H cannot be mistakenly reported, an original protocol architecture and original hierarchical divisions cannot be damaged, and low complexitycan be achieved.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, relates to a method for reporting received data status in a private network wireless communication system. Background technique [0002] At present, the 230MHz frequency band is mainly used in data transmission stations, and undertakes the collection of remote data. Because the rate provided by this frequency band is very low, only some simple communication applications can be used, so it cannot meet the increasing business diversification and large data flow requirements of smart grids and sensor networks. According to the future planning of the State Grid, it is necessary to find a new broadband communication technology to meet the business needs of its distribution network automation, load management, electricity consumption information collection, smart grid user services, emergency repairs and video surveillance in special areas. [0003] The 230MHz freq...
