1. A method performed by a first wireless access network node for providing random network access configuration to one or more mobile stations, comprising:
receiving a message from a second wireless access network node comprising an indicator for updating random access channel configuration at the first wireless access network node;
obtaining, based on the message, an optimized random access channel configuration for the first wireless access network node for reducing contention among the one or more mobile stations in obtaining network resource for random access to the first wireless access network node;
broadcasting the optimized random access channel configuration optimized for the first wireless access network node to the one or more mobile stations; and
receiving a random access request generated by one of the one or more mobile stations and transmitted according to transmission parameters selected from a plurality of transmission parameters indicated in the optimized random access channel configuration,
wherein the indicator is generated by the second wireless access network node, and the message is sent by the second wireless access network node and received by the first wireless access network node in response to the indicator being higher than a predetermined threshold value; and
wherein the indicator comprises an aggregation of any combination of flag for random access channel optimization, cell information, beam or synchronization signal and physical broadcast channel information, uplink or supplementary uplink information, or high speed mode support information.
