LINK-FAULT TOLERANCE IN A DISTRIBUTED ANTENNA SYSTEM

摘要

Certain features relate to improving the link-fault tolerance in a distributed antenna system (DAS) by utilizing a series of synchronous Ethernet frames. A receiving remote unit or a head-end unit in the DAS can predict the start of incoming Ethernet frames based on frame information extracted from previously received Ethernet frames. For example, a remote unit can be configured to receive one or more Ethernet frames, each of the one or more Ethernet frames including a start-of-frame field. After a period of time corresponding to the frame repetition rate, the remote unit can search for an additional start-of-frame field, indicating the receipt of the next Ethernet frame. The remote unit can extract the payload data from the next Ethernet frame based on the predicted value for the additional start-of-frame field.

1. A method, comprising:
receiving, by a remote unit of a distributed antenna system, one or more Ethernet frames, each of the one or more Ethernet frames including a start-of-frame field, the one or more Ethernet frames associated with a frame repetition rate; extracting a payload of a first Ethernet frame of the of the one or more Ethernet frames based on the start-of-frame field included in the first Ethernet frame; predicting, after a period of time corresponding to the frame repetition rate, a value for an additional start-of-frame field included in an additional Ethernet frame; and extracting an additional payload from the additional Ethernet frame based on the value for the additional start-of-frame field.
