The present invention relates to the field of communications. Disclosed are an MBMS error processing method, a communications node, and a communications system, which are designed for solving the problem in the prior art that data cannot be transmitted in time when an MBMS error occurs. The method comprises: receiving indication information of an MBMS error; establishing a unicast bearer according to the indication information; and sending data through the unicast bearer, the data being data that a user equipment is receiving through an MBMS bearer or data that the user equipment is interested in to receive when the MBMS error occurs. Also disclosed is a computer storage medium.

A method begins with a managing unit establishing an access policy that designates, for a first group of user devices, a first read time window and a first write time window. The method continues with a storage unit receiving an access request from a user device. The method continues with the storage unit determine whether the access request is received within the first read time window or whether the access request is received within the first write time window. The method continues with the storage unit generating a read response that includes encoded data slices when the access request is a read request and is received within the first read time window. The method continues with the storage unit processing the write request to store encoded data slices when the access request is the write request and is received within the first write time window.
