Publication number: 20180343590Abstract: 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.Type: ApplicationFiled: August 1, 2018Publication date: November 29, 2018Applicant: Huawei Technologies Co., Ltd.Inventors: Sichen Wang, Jiaxin Yin, Yongjing Zhang, Mitch Tseng

Publication number: 20180310141Abstract: 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.Type: ApplicationFiled: June 15, 2018Publication date: October 25, 2018Inventors: Jiaxin Yin, Sichen Wang, Ying Gao, Jiaming Wu, Yaoye Zhang, Yongjing Zhang

Publication number: 20170095178Abstract: 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.Type: ApplicationFiled: April 11, 2016Publication date: April 6, 2017Inventors: Marco Schoen, Kurt Scott, Feng Lin, Sichen Wang, Yun Zhang, Lin Yang

Patent number: 8351585Abstract: 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.Type: GrantFiled: December 24, 2009Date of Patent: January 8, 2013Assignee: Huawei Technologies Co., Ltd.Inventors: Lingyan Wu, Yuan Bao, Guojun Xu, Haoyu Wang, Shanyang Ke, Sichen Wang, Ruinan Sun

Patent number: 8320530Abstract: 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.Type: GrantFiled: May 4, 2009Date of Patent: November 27, 2012Assignee: Huawei Technologies Co., Ltd.Inventors: Sichen Wang, Hui Huang, Peng Wang
