Method and apparatus for data communication while base station is disrupted in wireless communication system
First Claim
1. A method for data communication while a Base Station (BS) is disrupted in a wireless communication system, the method comprising:
- responsive to a plurality of Mobile Stations (MSs) receiving a preamble signal from a cluster header through a dedicated control channel while the BS is disrupted, transmitting a message requesting cluster member subscription to the cluster header;
configuring, in a cluster header, a cluster member list, and broadcasting the cluster member list;
receiving a data transmission request message at the cluster header from a source MS using the broadcasted cluster member list; and
one of unicasting and broadcasting a response message for the data transmission request of the source MS to a target MS among the plurality of MSs based on the response message.

Abstract
A method provides data communication while a Base Station (BS) is disrupted in a wireless communication system. The method includes, when a plurality of Mobile Stations (MSs) receive a preamble signal from a cluster header through a dedicated control channel while the BS is disrupted, sending a message requesting cluster member subscription to the cluster header, in the cluster header, including the plurality of MSs in a cluster member, configuring a cluster member list, and broadcasting the cluster member list, in a source MS among the plurality of MSs, sending a data transmission request message to the cluster header using the broadcasted cluster member list, in the cluster header, one of unicasting and broadcasting a response message for the data transmission request of the source MS, and, in the source MS, transmitting data to a target MS among the plurality of MSs based on the response message.
