Abstract: A wearable device and an image signal processing apparatus thereof are provided. The image signal processing apparatus comprises an image acquisition device, an image data processing module, and an application processor; the application processor is used for controlling, when detecting that the wearable device enables a shooting preview mode, the image data processing module to switch from a sleep state or a power-down state to a working state; the image acquisition device is used for acquiring original image data; the image data processing module is used for obtaining the original image data and processing the original image data.

Abstract: Disclosed are a system-on-chip and a method for managing a working mode thereof, and a smart wearable device. The method comprises the following steps: in a working mode, a master control subsystem controlling a functional subsystem to implement a corresponding function, and responding to interrupt signals of the functional subsystem and a secondary control subsystem; in a dormant mode, the secondary control subsystem responding to the interrupt signal of the functional subsystem, and the master control subsystem prohibiting responding to the interrupt signal of the functional subsystem; and in an ultra-low power consumption mode, the master subsystem being powered off, and the secondary control subsystem responding to the interrupt signal of the functional subsystem. In the present disclosure, on the premise of meeting a normal function requirement of the system-on-chip, the power consumption of the system-on-chip is reduced to the greatest possible extent.

Abstract: A method for implementing MIP registration or deregistration includes obtaining, by a physical entity in which a destination MIP Foreign Agent (FA) resides, an identity of a mobile terminal (MT ID) and address information of an anchor proxy mobile node or an authenticator; sending a message carrying the MT ID to the anchor proxy mobile node or the authenticator; and implementing MIP registration or deregistration for the mobile terminal corresponding to the MT ID using a credential, in which the credential corresponding to the MT ID is acquired from the anchor proxy mobile node or authenticator.

Abstract: A method, a system and an apparatus for performing mobile Internet protocol deregistering, includes that the network element in the ASN to which the terminal attaches detects whether the MS terminates unconventionally, and sends the message with the MS identifier of the MS which terminates unconventionally to the ASN GW/DP. The ASN GW/DP instructs the ASN GW/FA to release the link resource with the MS and release the link resource with the HA proving service for the MS.

Abstract: Embodiments of the present invention provide a method for receiving Multicast and Broadcast Service (MBS), include: adding information of a next MBS_MAP message in a current MBS_MAP message; determining receiving information of the next MBS_MAP message according to the current MBS_MAP message and the information added in the current MBS_MAP message, receiving the next MBS_MAP message according to the receiving information determined, and receiving the MBS service according to the next MBS_MAP message received. The embodiments of the present invention also provide two other methods, apparatus and a system for receiving the MBS service. The method, system and apparatus provided by the embodiments of the present invention implement the continuous receiving of the MBS service without the requirement of frequent receiving the DL_MAP message.
