  • Publication number: 20180343590
    Abstract: Embodiments of the present invention disclose a resource obtaining method and a related device, to effectively reduce redundant data transmission between a registrar and a resource server. The method in the embodiments of the present invention includes: receiving, by a registrar, a first request sent by a terminal for obtaining a target attribute included in a resource, where the first request carries a uniform resource identifier URI of the target attribute; determining, by the registrar based on the URI, that the registrar stores the resource to which the target attribute belongs, where the target attribute is partial content included in the resource; and sending, by the registrar to the terminal, a valid target attribute indicated by the URI. The embodiments of the present invention further provide a registrar and a resource server, effectively reducing redundant data transmission between the registrar and the resource server, and saving a network resource.

  • Publication number: 20180310141
    Abstract: A mobile network platform creates a device group according to a member device supporting a mobile network multicast communication manner in a Machine-to-Machine Communications (M2M) group, generates an identifier of an external group corresponding to the device group, and requests a service capability exposure function (SCEF) to create the external group according to the identifier of the external group and an external device identifier of the member device supporting the mobile network multicast communication manner. When receiving an access request for the M2M group, the mobile network platform obtains the device group in the M2M group, learns of the corresponding external group, and then requests the SCEF to access the member device in the external group in a multicast communication manner. Hence, an amount of information generated due to interaction between an M2M platform and an M2M device is reduced, while reducing resource overheads.

  • Publication number: 20170095178
    Abstract: A system for the detection, recording, and analysis of EMG data attained during exercise in real-time is described. The system employs a surface EMG sensor equipped with a Bluetooth or a Wi-Fi module. The sensor transmits sEMG data via Bluetooth or Wi-Fi to a smart device, which processes this data utilizing a preloaded application and informs the user of the efficacy of exercises with key statistics in real-time. A sensor box containing the EMG sensor also contains a pre-amplification circuit, an amplification circuit, a DC-offset circuit, and a signal smoothing and amplifier circuit to maximize the reduction of extraneous noise frequently observed with conventional sEMG sensors. A proprietary mobile device application receives, interprets, records, and displays the EMG data for the user.

  • Patent number: 8351585
    Abstract: A method, system and apparatus for implementing a Multimedia Ring Back Tone (MRBT) service are provided. The method includes: receiving a call request originated by a calling terminal; parsing a tone playing policy specifying whether to play a caller tone or a callee tone or whether to filter a tone; performing caller tone media negotiation or callee tone media negotiation, or performing no tone negotiation according to the parsing result; and playing the caller tone or the callee tone to the caller, or playing no tone. With the technical solution of the present invention, the caller tone service can be implemented in the IMS domain. Whether a caller tone or a callee tone is played to the caller is determined according to a preset policy. Furthermore, the tone filtering service is also implemented. This gives a user freedom in experiencing the MRBT service.

  • Patent number: 8320530
    Abstract: A method for realizing a multimedia call includes the following steps. A call request initiated by a calling terminal is received. An indication of the multimedia negotiation capability of the calling terminal is acquired, in which the indication of the multimedia negotiation capability identifies whether the terminal has the capability of supporting multiple multimedia negotiations or not. It is determined, according to the indication of the multimedia negotiation capability, whether the calling terminal has the capability of supporting multiple multimedia negotiations or not. A multimedia call connection is performed according to the multimedia negotiation capability of the calling terminal. It is determined, according to the factor whether the calling terminal has the capability of supporting multiple multimedia negotiations or not, how to perform the multimedia call connection, so as to flexibly realize the multimedia call connection accordingly.

  • Publication number: 20110143732
    Abstract: A method, an apparatus, a system, User Equipment (UE), and a server for receiving and delivering a media service are disclosed. The method for receiving a media service includes: judging whether a call setup request carries a media service identifier; and receiving media information indicated by the media service identifier if the call setup request carries the media service identifier. At the time of exchanging information, an identifier is carried in the information to indicate the attribute of the media information to be received by the UE, and therefore, the UE can notify the imminent or ongoing service to the user and prepare for receiving the media information according to the attribute of the media information. The identifier also indicates the media service processing capability of the UE, and corresponding operations are performed according to different capabilities of the UE. Therefore, the UE receives the media information that matches its media service processing capability.
