Wireless network system and communication method thereof

Abstract

The embodiment of the invention discloses a wireless network system, which comprises a controller resource cell including all or some controllers in a wireless network. The controller resource cell includes a first controller and a second controller. The first controller is used for establishing a master attribution link with a base station, and the second controller is used for establishing a slave attribution link with the base station. When the master attribution link fails, the second controller is used for establishing a new master attribution link with the base station. The embodiment of the invention further discloses a communication method of the wireless network system, a controller and a base station. The scheme provided by the embodiment of the invention improves the reliability of network, increases utilization ratio of device resources and resistance to burst flow, reduces cost, shortens time for disaster-tolerant switching / interrupting service, and can satisfy high reliability requirement of a network operator.

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...

Problems solved by technology

[0008] After analysis, the inventor believes that the success rate of disaster recovery switching in the first network architecture decreases, resulting in low reliability of the entire disaster recovery solution and a long time for disaster recovery switching

[0009] The second type of network architecture has huge disaster recovery projects and slow recovery speed, resulting in low reliability of the entire disaster recovery solution
