The embodiment of the invention discloses a method and a device for switching into a system supporting the multi-input multi-output technology, and relates to the technical field of mobile communication. In order to solve the problem that in the prior art, an inter-system is switched into a 3G system supporting the MIMO function, the 3G system only can establish a mobile terminal on the HSDPA loadbearing of a physical layer, but can not fully utilize the MIMO function supporting a MIMO system, the method and a device are provided. The embodiment of the invention provides the method for switching into the system supporting the multi-input multi-output technology, which comprises the following steps: acquiring mobile terminal capability information and target system capability information switched by the same through a radio network controller RNC; determining whether UE and a target system switched by the UE support the multi-input and multi-output technology or not according to the mobile terminal UE capability information and the target system capability information switched by the same; and if the mobile terminal and the target system switched by the same support the multi-inputand multi-output technology, issuing inter-system switching instruction messages carrying MIMO parameters information. The method can increase the system capacity.
Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for switching into a system supporting multiple input and multiple output technologies. Background technique [0002] With the continuous development of mobile communication and the Internet, in the 3G (3rd Generation, third generation mobile communication) system, the functions completed by RNC (Radio Network Controller, radio network controller) are no longer like 2G (2nd Generation, second generation) The BSC (Base Station Controller, base station console) in the mobile communication) system only manages wireless resources and terrestrial resources, and the 3G system also involves participation in high-speed network call admission control algorithms related to QoS (Quality of Service, Quality of Service); Negotiation of network resources between users and the core network; complete monitoring of switching of 1u interface, etc. Wherein, the 3G ...
