Wireless access network and wireless access system and method

Abstract

This invention relates to a radio access network, a system and a method, in which, the network includes: a signaling server of the control side, a data transmission server of the user side, a radio base station device, a RF connection controller and a RF device, the access system includes one or multiple radio access networks and one or many core networks, the access method includes: the RF device receives the access request signals of the radio terminal and its connection controller transmits them to the radio base station device, which transfers the data of the signaling side to the signaling server of the control side and transfers the data to the data transfer server to be processed and transmitted to the core network to be processed, then the signals received by the core network are sent to the user terminal by a counter process.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a wireless access network and a wireless access system and method. Background technique [0002] The existing UMTS (Universal Mobile Telecommunications System, universal mobile communication system) system is a third-generation mobile communication system that adopts WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) air interface technology, and the UMTS system is usually called It is a WCDMA communication system. The UMTS system adopts a structure similar to that of the second generation mobile communication system, including a radio access network (Radio Access Network, RAN) and a core network (Core Network, CN). Among them, the wireless access network is used to handle all wireless-related functions, while the CN handles all voice calls and data connections in the UMTS system, and realizes switching and routing functions with ...

Problems solved by technology

[0006] The above network architecture is based on the 3GPP Release 4 / 5 / 6 protocol, and its user plane and signaling plane are in the same physical entity, which has poor scalability; the base station and radio frequency cannot be separated, making it difficult to realize site sharing and radio frequency sharing; The failure of nodes in the network will lead to the interruption of services provided within the range controlled by the nodes; and it does not consider how different wireless technologies access the 3GPP core network

[0007] As the 3GPP network evolves to an all-IP network, its original access network cannot be further improved in terms of efficiency, function, and fault tolerance. Therefore, a new access network is needed to meet the improvement of network capabilities. At the same time reduce the cost of network construction, and allow different access technologies to utilize the rich resources and service functions of the 3GPP core network
