Assignment and handover in a radio communication network

Systems and methods related to performing an assignment and a handover in a radio communication network are provided. In one exemplary embodiment, a method performed by a Mobile Switching Center (MSC) of a radio communication network may include seizing resources for a Time Division Multiplexed (TDM) bearer and an Internet Protocol (IP) bearer for use on a terrestrial A-interface of the radio communication network for an activity to be performed by a target Base Station Controller (BSC) of the radio communication network. Further, the method may include sending, to the target BSC, an indication that requests the activity be performed by the target BSC and that also identifies the seized resources for the TDM bearer and the IP bearer for use on the terrestrial A-interface for the activity
