    摘要： Systems, methods, and apparatus are described that employ specially designed interference patterns to build an in-band side channel without degrading the effective throughput of the main channel. A first device (100) includes a control component (130) that generates control information and an interference component (140) that transmits the control information (450) through emission of patterned interference data concurrently while other users are transmitting other data (420). A second device (300) receives the patterned interference data and the other data via a single antenna (350) and decodes the patterned interference data to extract the control data (450). The first device (100) transmits the other data (420) on a side channel (440) that resides in the same spectrum as the main channel (410) in which the other data (420) is emitted. The first device (100) encodes the interference patterns such that the control data (450) can be safely transmitted and extracted without effecting other data transmission. In one aspect, devices (100, 200, 300) can employ a dynamic cooperation multi-access channel (DC-MAC) protocol (1510) to schedule transmission of the other data (420) on the main channel (410), and to employ the side channel (440) for control and coordination.

    摘要： A method and device for detaching a user equipment (UE) are disclosed in the present invention. The UE is registered with a mobility management entity (MME) in a packet switched (PS) network and a mobile switching center (MSC) in a circuit switched (CS) network. When the UE needs to detach from the PS network, the MSC receives a Detach Request with a Detach Type indicating the detaching from the PS network only; after receiving the Detach Request, the MSC deletes the context of the PS core network entity and clears the connection between the MSC and the MME. An MME for performing UE detachment is also disclosed in the present invention. The present invention helps reduce the time delay during the subsequent handover and quickly provide users with communications services, so as to improve user's experience and meet the carriers' requirements.
