Mehtod and apparatus for handover in a heterogeneous wireless communication system

The present invention relates to a method and system for providing handover in a heterogeneous wireless communication network. The present invention provides a handover method between the LTE system and the CS system. The process according to the invention, uses a single radio channel in a call manager of a network having an IMS network for anchoring an LTE network and a call to provide a CS network and a packet communication service of a voice call (Circuit Call), the CS to a terminal which can be connected with the network to the LTE network in a LTE network, the method for providing a handover to the CS network, when from the terminal become a handover request to the base station of the CS network through a node of the LTE network, process to a process with the subscriber station and the session with the partner terminal in communication to set the switches and circuits of the CS network needs to change to the call manager set up and the call manager IP bearer between the opposing terminal, the IP to the terminal during bearer service to the handover command comprises the step of setting to the base station and the radio channel of the CS network. Heterogeneous network handover, LTE, CS.
