A method of a mobile device for performing communication with at least one peripheral device in a wireless communication system, the method comprising: if the mobile device receives emergency communication related information transmitted from another user's mobile device that senses an emergency situation, or receives the emergency communication related information from a base station, the mobile device operating as a temporary client for the emergency communication; else if the mobile device neither receives emergency communication related information transmitted from another user's mobile device that senses an emergency situation, nor receives the emergency communication related information from a base station, the mobile device: determining to operate as a temporary host, activating an emergency mode and connecting with at least one peripheral device, collecting status information associated with the at least one connected peripheral device, checking access status with a base station and if access with the base station is possible, transferring the obtained status information for the at least one peripheral device to the base station and, upon receiving host indication information from the base station, transferring the host indication information to the peripheral device indicated by the host indication information, and receiving control information from the peripheral device, the method characterized by further steps of: else if the access with the base station is not possible, determining a priority of status information of the mobile device and a priority status of the at least one peripheral device, and determining the host for the emergency communication supported on the emergency mode among the mobile device and the at least one peripheral device based on the determined priority. if the mobile device receives emergency communication related information transmitted from another user's mobile device that senses an emergency situation, or receives the emergency communication related information from a base station, the mobile device operating as a temporary client for the emergency communication; else if the mobile device neither receives emergency communication related information transmitted from another user's mobile device that senses an emergency situation, nor receives the emergency communication related information from a base station, the mobile device: determining to operate as a temporary host, activating an emergency mode and connecting with at least one peripheral device, collecting status information associated with the at least one connected peripheral device, checking access status with a base station and if access with the base station is possible, transferring the obtained status information for the at least one peripheral device to the base station and, upon receiving host indication information from the base station, transferring the host indication information to the peripheral device indicated by the host indication information, and receiving control information from the peripheral device, determining to operate as a temporary host, activating an emergency mode and connecting with at least one peripheral device, collecting status information associated with the at least one connected peripheral device, checking access status with a base station and if access with the base station is possible, transferring the obtained status information for the at least one peripheral device to the base station and, upon receiving host indication information from the base station, transferring the host indication information to the peripheral device indicated by the host indication information, and receiving control information from the peripheral device, the method characterized by further steps of: else if the access with the base station is not possible, determining a priority of status information of the mobile device and a priority status of the at least one peripheral device, and determining the host for the emergency communication supported on the emergency mode among the mobile device and the at least one peripheral device based on the determined priority. else if the access with the base station is not possible, determining a priority of status information of the mobile device and a priority status of the at least one peripheral device, and determining the host for the emergency communication supported on the emergency mode among the mobile device and the at least one peripheral device based on the determined priority.
