Patent number: 9839021Abstract: A method, an apparatus and a system for selecting a downlink primary carrier for transmitting data are disclosed. The method includes the following steps: A terminal obtains primary carrier selection information configured by a network; and the terminal determines a downlink carrier corresponding to an uplink carrier of the terminal as a downlink primary carrier for transmitting data according to the primary carrier selection information. In the embodiments of the present invention, the network selects a downlink carrier corresponding to an uplink carrier of the terminal as a downlink primary carrier for transmitting data. The terminal needs to detect only the downlink primary carrier, and the downlink carrier needs to be switched or detected only if the primary carrier receives a signaling message for detecting or receiving other carriers, so it is not necessary to switch or detect the downlink carrier frequently, which reduces battery consumption of the terminal.Type: GrantFiled: September 16, 2014Date of Patent: December 5, 2017Assignee: Huawei Technologies Co., Ltd.Inventors: Lixia Xue, Yujuan He, Chaojun Li

Patent number: 9763133Abstract: A plurality of cache servers, connected to a packet forwarding apparatus, forwarding a packet transmitted and received between a storage apparatus that holds a content under management in store and a user terminal, temporarily holds at least part of the content under management in store. A controller decides an on-screen resolution at the terminal, based on information contained in a content request message from the terminal, and selects a cache server that holds a content of the on-screen resolution in store. The controller instructs the selected cache server to deliver the content. The cache server instructed calculates a bit rate based on a signal received from the terminal. The cache server reads content from the terminal, which is to have the on-screen resolution and a bit rate not higher than the calculated bit rate. The content is stored in a packet and transmitted, then delivered without reducing the user's QoE.Type: GrantFiled: July 4, 2012Date of Patent: September 12, 2017Assignee: Rakuten, Inc.Inventor: Kazunori Ozawa
