eu improvement in fdd-tdd joint operation networks

摘要

summary eu enhancement in fdd-tdd joint operation networks to support new features where fdd carriers and tdd carriers offer different services with different qos or with different coverage or different mobility robustness, network eu enhancements of fdd-tdd are proposed. In one embodiment, an idle dual mode eu cams in a source cell and determines a target cell based on the cn domain and / or additional paging information contained in an enhanced paging message. in another embodiment, a dual mode eu may establish an rrc connection to a tdd bearer source cell, then be handovered or redirected to a target cell supporting voice over ims. handover or redirection is based on the cn domain and / or the additional paging information contained in the enhanced paging message.
