摘要：Mobile business can only be used within the coverage area of the wireless networks at present. If there is some temporary utilization such as emergency business in disaster area and some conferences or link failure, the users cannot receive M-business services. Owing to the infrastructureless structure and self-organized feature of 4G system, this paper proposes 4G-based mobile business model supported for emergency environment (EMBM). EMBM consists of cluster structure based on 4G system, Bi-connectivity backbone network construction and node business-function setting. The most important novelty of EMBM is that it can be used in emergency environment. The cluster structure is infrastructureless. EMBM constructs Bi-connectivity backbone network based on relevant theorem in graph theory and algorithm in computation geometry, such Bi-connectivity structure can provide real-time multimedia services to Mobile business. ? 2010 IEEE.
