Abstract: A contrast enhanced imaging method and system, under a first mode, include: transmitting ultrasonic waves at a first frame rate to a tissue containing micro-bubbles and receiving echo signals thereof to generate a first contrast enhanced image; transmitting ultrasonic waves at a second frame rate greater than the first frame rate and receiving echo signals thereof to generate a second contrast enhanced image; and generating a super-resolution image; and may, under a second mode, include: transmitting ultrasonic waves at a third frame rate greater than the first frame rate to the target tissue containing the contrast micro-bubbles and receiving echo signals thereof to generate a third contrast enhanced image; freezing the third contrast enhanced image; and generating a super-resolution image based on the echo signals of the third ultrasonic waves for a period of time before freezing. With the present disclosure, users can easily collect the data for super-resolution imaging.

Abstract: Embodiments of the present invention relate to a radio self-backhaul method, device, and system in an evolved network. With the radio self-backhaul method, device, and system provided in the embodiments of the present invention, the NodeB sends the uplink data to the core network by using the cable transmission link without occupying the radio resources of other NodeBs. This implements the radio self-backhaul for the NodeB, saves the radio transmission resources of the NodeB, and mitigates the impact on the radio network throughput.

Abstract: A method, a device, and a system for transmitting Packet Switched (PS) services are provided. The method includes: receiving an Activate Packet Data Protocol (PDP) Context Request message of PS services sent by a User Equipment (UE), in which the Activate PDP Context Request message carries an Access Point Name (APN) for identifying a first service network or a second service network (s201); establishing a corresponding transmission channel according to the APN (s202); and transmitting the PS services to the corresponding service network through the established transmission channel (s203). Through the method and the device, different networks are selected to transmit the PS services according to the APN for identifying different networks in the Activate PDP Context Request message of PS services sent from the UE, thereby implementing distribution of the PS services.

Abstract: Embodiments of the present invention disclose a method, a communication apparatus and a communication system for handover processing. The method for handover processing includes: when a terminal having a capability of supporting an optimized handover and a non-optimized handover needs to be handed over from a first network to a second network, determining whether the terminal is incapable of performing an optimized handover, if it is determined that the terminal is incapable of performing the optimized handover, performing a non-optimized handover. The embodiments of the present invention further provide a communication apparatus and a communication system accordingly. The technical solutions enable a handover between different networks to be implemented in more scenarios.

Abstract: A system and method for supporting handovers between different radio access technologies is provided. A method for communications device operations includes sending a request to a controller of the communications device to change an operating mode of the communications device, and receiving a transmission responsive to the request. The method also includes in response to determining that the controller has granted the request to change the operating mode and that the communications device is operating in a border cell, changing the operating mode of the communications device, tuning at least one receiver of the communications device to an alternate radio access technology (RAT), and initiating a handover with the alternate RAT.
