Abstract

The invention discloses a dense user area-orientated wireless network reconstructed communication method, which belongs to the technical field of honeycomb mobile communication networks. The method is characterized in that: the method is realized among the terminals, a base station, a wireless network controller and a core network (CN), and according to the distance information between communication terminals and the request of the terminals, the base station determines that the current communication between different terminals adopts conventional communication, direct communication of point-to-point terminals or direct communication of autonomous multicast terminals, and then sends the selective communication mode and the corresponding transmission information to the communication terminals in a signaling mode to perform control; the CN takes charge of judging the cell home of the terminals, performing authentication and encryption and acquiring terminal position information; and the wireless network controller calculates the distance between the communication terminals. The method has the advantages of low signaling overhead, frequency spectrum resource saving, reduction of transmitting power consumption and improvement of capacity of network users.

Description

technical field [0001] The present invention provides a wireless network reconfiguration communication method oriented to a dense user area, which belongs to the field of communication technology, and particularly relates to a physical architecture based on an existing cellular mobile communication network. According to the location information of a mobile terminal and user requests, The method of realizing conventional communication with variable logical structure, point-to-point terminal direct communication and autonomous multicast terminal direct communication through signaling control is mainly used to meet the needs of large-capacity user access in dense user areas. Background technique [0002] The wireless network represented by mobile communication and wireless local area network has become an important high-tech pillar industry in all countries in the world. At present, the commercial third-generation mobile communication system (3G) is developing steadily; the rap...
