Wireless network system and communication method thereof

Abstract

The embodiment of the invention discloses a wireless network system. The wireless network system comprises a controller resource pool which is formed by all or part of controllers in a wireless network; the controller resource pool comprises a first controller and a second controller, wherein the first controller is used for establishing a primary affiliation connection with a base station, and the second controller is used for establishing a secondary affiliation connection with the base station and establishing a new primary affiliation connection with the base station when a fault occurs in the primary affiliation connection. The embodiment of the invention also discloses a communication method of the wireless network system, the controllers and the base station. By the scheme provided by the embodiment of the invention, the reliability of the network is improved, the utilization ratio of equipment resources is increased, the capability of burst flow resistance is improved, the cost is reduced, the service interrupting time by fault-tolerant switching is shortened, and the requirement for high reliability of an operator is met.

Description

technical field [0001] The invention relates to the communication field, in particular to a wireless network system and a communication method thereof. Background technique [0002] With the explosive growth of demand for mobile services, such as voice services and data services, operators begin to increase capacity requirements for base station controllers in the radio access network, such as radio network controllers (Radio Network Controller, RNC). Technological progress has provided a guarantee for a substantial increase in equipment capacity and integration. While its capacity is increasing, the responsibility of the base station controller as the core part of the wireless access network is gradually increasing. [0003] Taking the Universal Mobile Telecommunications System (UMTS) system as an example, the RNC in the network system is connected to surrounding network elements such as core network and base station through various interfaces. The interface connection ca...
